de novo kaposi's sarcoma in renal transplantation. case report and brief review.this report describes a de novo development of kaposi's sarcoma in a puerto-rician man 9 months after a cadaveric renal transplant. progression of the disease was observed despite local irradiation, while the patient remained immunosuppressed with prednisone and azathioprine. this was accompanied by depressed immunologic tests. discontinuation of azathioprine and addition of chemotherapy (bleomycin and vincristine), while continuing prednisone to maintain functional survival of renal allograft, ...197659624
partial characterization of a herpes-type virus (k9v) derived from kaposi's sarcoma.a herpes-type virus that was originally isolated from a cell culture (designated k9v) derived from a tumor biopsy specimen from a patient with kaposi's sarcoma was partially characterized. the host range of k9v, as determined by the induction of virus-specific cytopathology, synthesis of antigens, and plaque formation, was limited to human cells and particularly to fibroblasts. immunofluorescence and complement fixation assays confirmed the specificity of the presence of cytomegalovirus (cmv)-ty ...1977195073
opportunistic infections and kaposi's sarcoma among haitians: evidence of a new acquired immunodeficiency state.twenty haitian patients, hospitalized from 1 april 1980 to 20 june 1982, had pneumocystis carinii pneumonia, central nervous system toxoplasmosis, esophageal candidiasis, cryptococcosis, disseminated cytomegalovirus, progressive herpes simplex virus, chronic enteric coccidiosis, or invasive kaposi's sarcoma. ten patients died. opportunistic infections were frequently multiple and were recurrent in three patients. in seven patients disseminated tuberculosis preceded the other infections by 2 to 1 ...19836299151
oncological consequences of impaired immune surveillance against ubiquitous viruses.the immune system is constantly challenged by ubiquitous viruses. multiple immune defenses have evolved to meet these challenges, and thus immunocompetent individuals successfully respond to infection without sequela. x-linked lymphoproliferative syndrome patients, renal allograft recipients, and acquired immunodeficiency syndrome patients share impaired immune surveillance as a common feature. such individuals are variously susceptible to numerous untoward complications following infection with ...19836309892
seminal fluid excretion of cytomegalovirus related to immunosuppression in homosexual men.seminal fluid samples from 84 danish homosexual men were successfully cultured to determine the prevalence of cytomegalovirus excretion. ten (15%) out of 66 men positive for the antibody were found to be excreting the virus. although the proportion excreting was inversely related to age (p less than 0.01), three men aged over 30 and with many years of homosexual experience excreted the virus. in addition, a 50 year old man with kaposi's sarcoma excreted the virus. a further study of the ratio of ...19836307459

hsv, cmv, and hpv in human neoplasia.we are studying the role of sexually transmitted viruses in the development of human tumors. the persistence of herpes simplex virus, cytomegalovirus, and human papillomavirus nucleic acid sequences has been examined using cloned viral dna sequences as probes. the relationship of the viruses to various stages in the progression of neoplasia is examined, with particular reference to the role of viral and/or cellular genes in the initiation, promotion, and maintenance of the neoplastic phenotype. ...19846330227
toxicity, immunosuppressive effects and carcinogenic potential of volatile nitrites: possible relationship to kaposi's sarcoma.volatile nitrite in the form of amyl nitrite was used for 100 years for the treatment of angina pectoris. in spite of recognized toxicity, its use in this form was considered safe. during the 1960s prescriptions were not required for purchase of amyl nitrite (called poppers) and its use for recreational purposes became popular. with reinstatement of the prescription requirement in 1969, non-medicinal, street-variety volatile nitrites were made commercially available in the form of mixtures of im ...19846150466
african kaposi's sarcoma and aids.16 zambian patients with kaposi's sarcoma (ks) were studied to determine whether they had evidence of lymphopenia with decreased t helper/t suppressor (th/ts) ratios or previous infection with opportunistic pathogens. serological tests for viruses commonly associated with the acquired immunodeficiency syndrome (aids) were also carried out. 12 patients had a decreased th/ts and 2 of these were also lymphopenic. serological evidence for infection with toxoplasma and with pneumocystis was present b ...19846142209
speculations on the viral etiology of acquired immune deficiency syndrome and kaposi's sarcoma.the acquired immune deficiency syndrome (aids) appeared in the united states in late 1978 and has spread at an epidemic rate through the four major coastal cities of this country. the disease appears to show the same epidemiologic distribution as hepatitis b virus infection, and for this reason, most investigators feel that this new disease is caused by a blood-borne sexually transmitted virus. a number of viral agents have been suggested as the cause of aids, but to date, no virus has been cons ...19846330223
lymphadenopathy-associated viral antibody in aids. immune correlations and definition of a carrier state.we investigated whether serologic evidence of lymphadenopathy-associated virus (lav), an exogenous human t-cell lymphotropic and cytopathic retrovirus, correlated with the acquisition and transmission of the acquired immunodeficiency syndrome (aids). serum from 17 of 25 patients with aids contained circulating igg anti-lav antibody (all of 5 adults with cancer and 6 of 12 adults and 6 of 8 children with opportunistic infections, with or without kaposi's sarcoma). all of eight homosexual men with ...19846092953
htlv-iii serology distinguishes atypical and endemic kaposi's sarcoma in africa.serum samples from african patients with kaposi's sarcoma and acquired-immuno-deficiency-syndrome-related (aids-related) disorders and from normal subjects in uganda and zambia were tested for antibodies to the human t-lymphotropic retroviruses (htlv) types i, ii, and iii. nearly 90% of patients with aids-related disorders or with atypical, aggressive kaposi's sarcoma were seropositive for htlv-iii in both countries, whereas only 17% of patients with classic endemic kaposi's sarcoma were seropos ...19852857417
the use of dna probes in studies of human cytomegalovirus.hybridization assays provide a sensitive and rapid means for studying the molecular biology of viral replication and for identifying viral nucleic acid in biological specimens. such assays are attractive because the detection of virus does not require intact virions or concomitant viral protein synthesis, both of which may be absent in a latently infected cell or in a virus-associated tumor. for molecular and clinical studies on human cytomegalovirus (hcmv), we have cloned and characterized subg ...19852992841
immunohistopathology of lymph nodes in htlv-iii infected homosexuals with persistent adenopathy or aids.lymph node biopsies from 43 male homosexuals with persistent generalized lymphadenopathy and from ten acquired immunodeficiency syndrome patients, all with serum antibodies to human t-cell leukemia virus iii, were studied with regard to histopathology, immunohistology, and t-cell subsets in cell suspensions. all acquired immunodeficiency syndrome biopsies except one with kaposi's sarcoma had the same histopathological pattern of follicular depletion, whereas the persistent generalized lymphadeno ...19852410110
aids epidemic sparks campaign to encourage condom use.the acquired immune deficiency syndrome (aids) is fueling a campaign that encourages use of the condom to combat the spread of sexually transmitted diseases. condom use is being advocated even when one partner is practicing another form of contraception. the threat of aids has spread beyond the original risk groups -- homosexual and bisexual men, intravenous drug users, and transfusion recipients -- to include heterosexual men and women. researchers from the centers for disease control said a ...198512280299
clinical investigations of lymphadenopathy, including lymph node biopsies, in 24 homosexual men with antibodies to the human t-cell lymphotropic virus type iii (htlv-iii).the findings of 27 lymph node biopsies performed on 24 homosexual patients with lymphadenopathy are presented. six had acquired immune deficiency syndrome (aids) and 18 lymphadenopathy only, of whom one subsequently developed aids. all these patients had antibodies to the human t-cell lymphotropic virus type iii (htlv-iii) suggesting that htlv-iii is currently the commonest cause of lymphadenopathy in homosexual men. the histopathological findings of six of seven nodes from aids patients showed ...19863004630
kaposi's sarcoma and htlv-iii: a study in nigerian adult males.sera from 37 adult nigerian men with kaposi's sarcoma (ks), 30 contemporaneous controls bearing primary cell carcinoma of the liver (pcl), and 150 healthy non-tumour-bearing negative controls were tested for antibody to human t-cell lymphotropic virus type iii/lymphadenopathy associated virus (htlv-iii/lav) by enzyme-linked immunosorbent assays (elisa). certain immunocellular functions were also measured: the chemotactic locomotion of peripheral blood monocytes towards casein, delayed-type cutan ...19863021963
hla-associated susceptibility to acquired immunodeficiency syndrome in italian patients with human-immunodeficiency-virus infection.to investigate the contribution of genetic susceptibility to infection with human immunodeficiency virus, 50 subjects with lymphadenopathy syndrome (las) and 7 subjects with acquired immunodeficiency syndrome (aids) and kaposi's sarcoma were typed for hla a, b, c, and dr antigens. the frequency of b35 was significantly higher in las patients who progressed to aids than in those who did not or in healthy controls. the association between dr5 and aids/kaposi's sarcoma was also confirmed in these p ...19862877328
eosinophilic vasculitis leading to amaurosis fugax in a patient with acquired immunodeficiency syndrome.a 49-year-old bisexual man with generalized lymphadenopathy and antihuman t lymphocyte virus, type iii, (htlv-iii) antibodies presented with recurrent, unilateral amaurosis fugax. a temporal artery biopsy specimen showed eosinophilic vasculitis. the patient then developed acquired immunodeficiency syndrome with kaposi's sarcoma. we describe this patient because of the unusual association of large vessel vasculitis and acquired immunodeficiency syndrome.19863767551
acquired immunodeficiency syndrome.the acquired immunodeficiency syndrome (aids) was recognized as a distinct clinical entity in 1981 and was characterized by unexplained opportunistic infections and an aggressive form of kaposi's sarcoma. high risk groups for contracting aids include homosexual men, parenteral drug users, hemophiliacs, recipients of blood and blood products, and heterosexual contacts of such individuals. immunologic abnormalities associated with aids include lymphopenia, functional t-cell deficits, b-lymphocyte ...19863331210
early warning skin signs in aids and persistent generalized lymphadenopathy.distinctive patterns of skin disease other than kaposi's sarcoma have been in patients with aids, in others with persistent generalized lymphadenopathy (pgl) and in a group at high risk of developing aids. we found a chronic acneiform folliculitis on the face, back, chest and buttocks, extensive cutaneous fungal infections and a striking neck and beard impetigo. these skin diseases were not present in asymptomatic male homosexual control subjects, 32% of whom were found to have antibodies to hum ...19863008802
epithelioid angiomatosis: a distinct vascular disorder in patients with the acquired immunodeficiency syndrome or aids-related complex.unusual cutaneous vascular neoplasms distinct from kaposi's sarcoma were observed in five patients with the acquired immunodeficiency syndrome (aids) or human immunodeficiency virus (hiv)-1 infection. the cutaneous lesions were solitary or multiple papules and nodules. in some patients the lesions also affected internal organs. histologically the neoplasms were composed of proliferating blood vessels and cells with epithelioid features. immunoperoxidase studies of one lesion showed that the cell ...19872887942
pathophysiology and epidemiology of epidemic kaposi's sarcoma.the epidemic form of kaposi's sarcoma (ks) that occurs in patients with the acquired immune deficiency syndrome (aids) produces lesions that, histopathologically, are indistinguishable from those of classical ks or of the endemic form of the disease seen in children and adults in certain areas of africa. there are, however, important differences in the pathogenesis of the disease in the different groups affected by the neoplasm. compared with classical ks in people of eastern european and medite ...19873299718
an autopsy-proved case of aids in taiwan.the first case of aids positively identified in a non-foreigner in taiwan was a 25-year-old unmarried male who had practiced homosexuality for ten years. the patient began to have abdominal pain accompanied with loose stools and weight loss in june 1985, followed by fever, cough, headache, dizziness, and loss of memory. facial hyperpigmentation and extensive oroesophageal candidiasis were noted. laboratory studies showed severe lymphopenia with a reversed t-helper to t-suppressor ratio, cutaneou ...19873304320
human immunodeficiency virus-associated kaposi's sarcoma in a pediatric renal transplant recipient.an 11-year-old boy developed kaposi's sarcoma and progressive t lymphocyte deficiency 5 years after cadaveric kidney transplantation for end-stage renal disease. he had received 17 individual red blood cell transfusions prior to and during transplantation in 1980. human immunodeficiency virus (hiv) was cultured from blood in cerebrospinal fluid and hiv antibodies were detected with enzyme immunoassay and immunoblot techniques. the recipient of the donor's other kidney was well and hiv antibody-n ...19873306430
oral mucosal manifestations of aids?oral lesions of opportunistic infections and neoplasms are associated with immunosuppression caused by the human immunodeficiency virus (hiv). these include oral candidiasis, viral lesions such as warts, herpes simplex, herpes zoster and hairy leukoplakia, as well as kaposi's sarcoma and an aggressive form of periodontal disease. many of these can occur as the first clinical signs of hiv infection. thus, careful oral examination is an important part of the clinical evaluation.19873315352
kaposi's sarcoma in a young man in absence of aids or other known causes of immune suppression.kaposi's sarcoma (ks) in young individuals is unusual and most often associated with cellular immunodeficiency caused by infective or other neoplastic diseases. it has recently been highly associated with the acquired immunodeficiency syndrome (aids). we report the case of a heterosexual 29 year aged man with no evidence of underlying malignancy or infectious diseases. antibodies to the human immunodeficiency virus (hiv) were absent on repeat testing. his immunological profile demonstrated eleva ...19873435654
effect of t4 count and cofactors on the incidence of aids in homosexual men infected with human immunodeficiency virus.we prospectively evaluated potential markers and cofactors for the acquired immunodeficiency syndrome (aids) in 86 homosexual men who were seropositive for human immunodeficiency virus antibodies. during three years of follow-up, 19 men developed aids. risk of aids was clearly predicted by the total number of circulating okt4-positive lymphocytes (t4 count) at enrollment, while the corresponding t8 count was unrelated to subsequent aids development. subjects in manhattan had a higher risk of kap ...19873491911
neoplastic complications of htlv-iii infection. lymphomas and solid tumors.neoplastic disease arose in 29 of 200 patients infected with human t lymphotropic virus type iii (htlv-iii) seen at a suburban hospital. seventeen patients had kaposi's sarcoma, one of whom also had colon carcinoma. nine patients had lymphoproliferative disorders (seven lymphomas, one t suppressor cell chronic lymphocytic leukemia, and one multiple myeloma), including three with concomitant kaposi's sarcoma and one with colon cancer. one other patient had colon cancer, one had a seminoma, and on ...19873493690
origin and transmission of aids. multi-use hypodermics and the threat to the soviet union: discussion paper.health authorities in the soviet union have attempted to downplay the prevalence of infection with human immunodeficiency virus (hiv) in the soviet population and to suppress the publication of scientific articles on acquired immunodeficiency syndrome (aids). nonetheless, there is some evidence that the ussr may have more aids cases than any other country in europe. particularly prevalent are cases of kaposi's sarcoma in persons under 40 years of age. it is hypothesized that the multi-use of ...19873612664
suramin therapy in aids and related disorders. report of the us suramin working group.suramin sodium is a reverse transcriptase inhibitor with in vitro activity against the human immunodeficiency virus (hiv), the causative agent of acquired immunodeficiency syndrome (aids). ninety-eight patients with aids manifest as opportunistic infections (n = 38), aids with kaposi's sarcoma (n = 38), aids-related complex (n = 20), or aids-associated non-hodgkin's lymphoma (nhl) (n = 2) were treated with suramin sodium at 0.5, 1.0, or 1.5 g/wk for six weeks followed by maintenance therapy with ...19873650339
aids in india: a report of three cases with review of literatures.sera from 3500 individuals including patients of non-hodgkin's lymphoma, patients with sexually transmitted diseases, leprosy, jail inmates, healthy laboratory workers and patients on hemodialysis were screened for antibodies against human immunodeficiency virus (hiv) as a sero surveillance exercise of one of the centers set up by the india council of medical research at the postgraduate institute of medical education & research, candigarh. three individuals were found to be strongly positive by ...19883048289
upper gastrointestinal kaposi's sarcoma in patients positive for hiv antibody without cutaneous disease.six patients with antibodies to the human immunodeficiency virus (hiv) and with persistent gastrointestinal symptoms of hiv infection but without cutaneous lesions of kaposi's sarcoma underwent endoscopy. four also underwent barium meal examination. in all six cases small lesions were seen in the stomach at endoscopy, and histological examination of biopsy specimens taken from the lesions confirmed the diagnosis of kaposi's sarcoma. the barium meal examinations were reported as normal in three p ...19883122968
t4+ cell production of interferon gamma and the clinical spectrum of patients at risk for and with acquired immunodeficiency syndrome.to fully characterize the relationship between the clinical manifestations of human immunodeficiency virus infection and t4+ cell defects, we determined t4+ cell number and interferon gamma (ifn-gamma) production in 238 patients. for asymptomatic homosexuals, patients with acquired immunodeficiency syndrome (aids)-related complex (arc), and patients with fully established aids, clinical status correlated linearly with both t4+ cell number and t4+ cell-derived (antigen-stimulated) ifn-gamma secre ...19883132901
cultured, aids-related kaposi's sarcoma cells express endothelial cell markers and are weakly malignant in vitro.up to 30% of patients with acquired immunodeficiency syndrome (aids) suffer from kaposi's sarcoma (aids-ks). the histogenesis and neoplastic nature of this tumor is still controversial. we have established cell cultures of ks biopsies from 7 patients with aids. all donors were seropositive for the human immunodeficiency virus i (hiv-i), cytomegalovirus (cmv) and hepatitis b virus (hbv). the tumors were histologically shown to be ks. cell cultures derived from these tumors all expressed the endot ...19883141299
antibody to the aids virus in kaposi's sarcoma in nigeria.the present study has investigated whether kaposi's sarcoma (ks) in nigeria is associated with infection with the aids virus variously called human t-cell lymphotropic virus type iii (htlv-iii), lymphadenopathy/aids virus (lav), and aids-associated retrovirus (arv). serum samples from 40 ks patients, 30 patients with malignant melanoma of the foot (contemporaneous controls), and 50 normal nontumour-bearing controls were tested for anti-aids virus antibody by enzyme-linked immunosorbent assay (el ...19883162540
[human immunodeficiency virus infections (hiv-1 and hiv-2) in dakar. epidemiologic and clinical aspects].the authors report on the results of an investigation carried out on 109 hiv seropositives ascertained by the dakar central hospital between february 20, 1987 and may 31, 1988. these seropositives affected 44 patients with aids (0.78% of admitted patients) and 65 seropositive people of which 43 blood donors (1.35% of donors). both viruses are present in about equal number: 50 hiv1 seropositives, 44 hiv2 seropositives, and 15 composite seropositives. sex-ratio is 3,9 in favour of males; this figu ...19883221781
cutaneous manifestations of human immunodeficiency virus in lusaka, zambia.of the 1124 human immunodeficiency virus (hiv)-infected patients studied, one or more cutaneous lesions were found in 113 (98.3%) of the 115 patients with acquired immunodeficiency syndrome (aids) and in 541 (53.6%) of 1009 patients with aids-related complex (arc). kaposi's sarcoma, multidermatomal, necrotic herpes zoster, and pruritic maculopapular rashes are common cutaneous manifestations of aids and its related complex (arc) in zambia. the maculopapular rash results from a lymphoplasmacytic ...19882971691
antibody-dependent cellular cytotoxicity (adcc)-mediated destruction of human immunodeficiency virus (hiv)-coated cd4+ t lymphocytes by acquired immunodeficiency syndrome (aids) effector cells.the acquired immunodeficiency syndrome (aids) is defined in clinical terms by the development of kaposi's sarcoma and/or severe opportunistic infections in persons without predisposing conditions. a hallmark of the syndrome has been a decrease in the number of cd4+ t helper cells. the reduction in the frequency of the cd4+ lymphocytes has been postulated to be primarily the result of human immunodeficiency virus (hiv) tropism and cytophathogenicity for the t-cell subset. yet only a small percent ...19882975670
ocular complications of the acquired immunodeficiency syndrome.the acquired immunodeficiency syndrome (aids) affects the ocular structures in several ways. kaposi's sarcoma has been observed on the bulbar conjunctiva of the globe. retinal complications, however, are of major concern. cotton-wool spots are commonly seen in aids patients and are usually of no consequence, except that they must be distinguished from the early stages of cytomegalovirus (cmv) retinitis, seen in 20-40% of these patients. cmv causes a necrotic-type retinitis potentially leading to ...19882845260
kaposi's sarcoma of the oral cavity: a study of 134 patients with a review of the pathogenesis, epidemiology, clinical aspects, and treatment.since our first description and profile of patients with kaposi's sarcoma (ks) in 1984, the relative rate of ks in patients with the acquired immunodeficiency syndrome has dropped from 34% to 20%. however, the absolute number is increasing. the pathogenesis of ks is still obscure, and its interaction with the human immunodeficiency virus infection remains unclear. cause of death is usually opportunistic infections in both endemic and epidemic ks. the most common intraoral site is the palate, whi ...19883059252
cytogenetic study of kaposi's sarcoma associated with acquired immunodeficiency syndrome.we performed cytogenetic studies on direct preparations and short-term cultures from kaposi's sarcoma cells obtained from malignant pericardial effusion. the patient, a 46-year-old man with human immunodeficiency virus infection, initially presented with metastatic kaposi's sarcoma. despite therapy, his tumor proved aggressive, and the patient died of widespread pulmonary involvement nine months after diagnosis. cytogenetic analysis revealed a predominant karyotype of 48,x,-y, t(2;7)(q32;q36), + ...19883395219
vitamin b12 malabsorption in patients with acquired immunodeficiency syndrome.we have examined 11 patients with the acquired immunodeficiency syndrome (aids) for evidence of subclinical vitamin b12 malabsorption. three subjects (27%) had low levels of vitamin b12. eight subjects (73%), including these 3 subjects plus 5 others with normal vitamin b12 levels, had abnormal schilling test results. in addition, 15% of an unselected population of 121 patients with aids and 7% of 27 patients without aids who were seropositive for human immunodeficiency virus type 1 (hiv-1) had l ...19892774781
biopsy pathology of hiv infection: experience at st stephen's hospital, london.in a 3 year period from the beginning of january 1985 to the end of december 1987, 474 biopsies obtained from 266 patients with serological evidence of human immunodeficiency virus infection were examined. most frequent were skin biopsies of which 52% showed kaposi's sarcoma, and transbronchial lung biopsies of which 40% showed pneumocystis carinii pneumonia. other opportunistic infections were much less common; mycobacterium avium intracellulare was found in six biopsies and cytomegalovirus in ...19892785082
empirical treatment without bronchoscopy for pneumocystis carinii pneumonia in the acquired immunodeficiency syndrome.an empirical approach to treating pneumocystis carinii pneumonia was adopted in a prospective study of 73 men with antibodies to human immunodeficiency virus 1 (hiv-1) presenting with respiratory problems. at presentation 49 patients (group 1) were thought to have a history, findings at clinical examination, chest radiograph, and arterial blood gas tensions typical of pneumocystis pneumonia, and empirical treatment was begun immediately. twenty four patients (group 2) were thought to have featur ...19892788935
erythroplastic lesion on the mandibular marginal gingiva.carcinoma of the gingiva is a significant risk to patients because the asymptomatic characteristics of erythroplastic lesions are not always readily identified. this case report shows the similarity in clinical appearance of squamous cell carcinoma of the gingiva to the common inflammatory changes associated with periodontal disease. a similar clinical presentation might be seen in any lesion with increased vascularity, including kaposi's sarcoma associated with human immunodeficiency virus infe ...19892794260
sporotrichosis in the acquired immunodeficiency syndrome.kaposi's sarcoma and disseminated sporotrichosis of the skin and joints developed simultaneously in a homosexual man with antibodies to human immunodeficiency virus. there was no identified source of exposure to sporothrix organisms. sporotrichosis may be a presenting opportunistic infection associated with acquired immunodeficiency syndrome and tends to be disseminated at the time of diagnosis.19892808849
bacillary (epithelioid) angiomatosis and concurrent kaposi's sarcoma in acquired immunodeficiency syndrome.two patients with acquired immunodeficiency syndrome developed simultaneous kaposi's sarcoma and bacillary (epithelioid) angiomatosis. the distinguishing clinical and histologic features of these two vascular proliferations associated with human immunodeficiency virus disease are described. the lesions of bacillary (epithelioid) angiomatosis contained bacteria, while the lesions of kaposi's sarcoma did not. with erythromycin therapy, the lesions of bacillary (epithelioid) angiomatosis cleared, w ...19892817918
recovery of human immunodeficiency virus and detection of p24 antigen in bronchoalveolar lavage fluid from adult patients with aids.published reports indicate that hiv is recovered from bal fluid of patients with aids who have lip but not with other aids-related pulmonary disease. our experience has been different. ten bal specimens from nine patients with aids were cultured directly in peripheral blood mononuclear cells, and all ten cultures were positive for hiv as indicated by examination of the culture supernatant by reverse transcriptase assay and enzyme immunoassay for hiv antigen. five of the specimens were also posit ...19892500312
non-cryptosporidial diarrhoea in human immunodeficiency virus (hiv) infected patients.thirty of 81 consecutive hiv antibody positive patients referred with non-cryptosporidial diarrhoea had no potential infectious cause; most had aids related complex rather than the full blown syndrome. opportunistic infections with cytomegalovirus (cmv), mycobacterium avium-intracellulare (mai), and herpes simplex virus (hsv), which allowed a diagnosis of aids to be made, were found in 19 patients and were the presenting features of aids in five. other potential pathogenic species included entam ...19892539310
cells derived from sporadic and aids-related kaposi's sarcoma reveal identical cytochemical and molecular properties in vitro.we have established 40 cell cultures from biopsies of 5 patients with sporadic kaposi's sarcoma (ks) and compared them with cell cultures derived from ks biopsies of aids patients. immunocytochemical staining of sporadic ks cells revealed the same endothelial cell markers as those expressed on aids-ks cells, indicating that both types of ks might be of endothelial cell origin. in contrast to clinical features, in vitro growth properties showed no differences. ks cells of both types reveal a low ...19892543647
oral manifestations of hiv infection in 75 dutch patients.seventy-five consecutive hiv-infected patients, including 33 aids cases were examined. one or more oral mucosal lesions were observed in 57 (76%); candidiasis was the most common finding (52%). others included hairy leukoplakia (16%), periodontal disease (16%) and kaposi's sarcoma (4%). diversity of study design and methods allowed no reliable comparison with other reports.19892545871
ocular manifestations of acquired immune deficiency syndrome.the ocular complications of acquired immune deficiency syndrome (aids) include: (1) a noninfectious microangiopathy, most often seen in the retina, consisting of cotton-wool spots with or without intraretinal hemorrhages and other microvascular abnormalities; (2) opportunistic ocular infections, primarily cytomegalovirus (cmv) retinitis; (3) conjunctival, eyelid, or orbital involvement by those neoplasms seen in patients with aids (i.e., kaposi's sarcoma and lymphoma); and (4) neuro-ophthalmic l ...19892549483
diagnosis of pulmonary disease in human immunodeficiency virus infection: role of transbronchial biopsy and bronchoalveolar lavage.the value of transbronchial biopsy and bronchoalveolar lavage was assessed in the diagnosis of pulmonary disease in patients infected with the human immunodeficiency virus (hiv). seventy four transbronchial biopsy and 66 bronchoalveolar lavage specimens (60 paired specimens) from 80 examinations in 64 patients were reviewed. pneumocystis carinii was the most common pathogen isolated (43 patients). bronchoalveolar lavage was superior to transbronchial biopsy for the diagnosis of this pathogen, th ...19892549653
aids-associated kaposi's sarcoma: a molecular model for its pathogenesis.kaposi's sarcoma is a mesenchymal tumor that is frequently observed in aids patients. although the tumor is clearly associated with hiv-1 infection, little is known about the molecular events underlying its pathogenesis. here we consider the potential roles of specific cytokines and the virally encoded tat product in inducing the tumor.19892561910
kaposi's sarcoma in a homosexual--10 years on.kaposi's sarcoma is seen in one of several clinical settings. before the recognition of the acquired immune deficiency syndrome (aids) in the early 1980s, the most frequent presentation of kaposi's sarcoma in the uk was the so-called 'classical' form of the disease. the most common form of kaposi's sarcoma in this country is now that associated with aids, which particularly affects young male homosexuals. here we describe a homosexual man who has developed many kaposi's sarcoma tumours during th ...19892591081
aids and the lung. introduction.damage to the immune system induced by the human immunodeficiency virus (hiv) leads to a spectrum of opportunistic infections of which the lung is the most common site. in europe and north america, pneumocystis carinii pneumonia is the presenting symptom in 64% of cases of acquired immunodeficiency syndrome (aids) and occurs at some point in 80% of aids victims. this infection is less common in africa, where tuberculosis is the predominant opportunistic infection. other aids-related lung infe ...19892595618
acquired immunodeficiency syndrome.a report entitled "kaposi's sarcoma and pneumocytosis carinii pneumonia among homosexual men in new york city and california" in the mmwr in july 1981 alerted the world to the appearance of a completely new disease. the opportunistic infections and cancers occurring in these patients had previously only been seen in patients who were immunosuppressed. homosexual men were the first as a major risk group to be identified. others quickly followed. the pattern of occurrence clearly indicated an infe ...19892599843
zidovudine for treating aids. what physicians need to know.zidovudine (retrovir) is the only drug found to be useful for managing human immunodeficiency virus (hiv) infection in patients with acquired immunodeficiency syndrome (aids) and aids-related complex. the drug is virostatic, ie, it prevents replication of hiv by inhibiting the enzyme reverse transcriptase. zidovudine is well tolerated and provides short-term benefits by improving the quality of life and extending survival time. it is expensive and can be toxic, however, so its use requires close ...19892662155
the chicago aids autopsy study: opportunistic infections, neoplasms, and findings from selected organ systems with a comparison to national data. chicago associated pathologists.the chicago acquired immunodeficiency syndrome (aids) autopsy study evaluated the first 38 aids autopsies through january 1, 1985 from 14 participating institutions in the chicago area. a complete analysis of neoplasms and opportunistic infections from this material as well as a discussion of pathologic features that may be associated only with human immunodeficiency virus (hiv) infection is presented and compared with national data. among the neoplasms nodular kaposi's sarcoma was present post- ...19892668939
[infection by the human immunodeficiency virus (hiv) in french guyana. dermato-venereologic problems].dermato-venereal manifestations in hiv infection and its severe evolution stage, aids, is of particular importance in tropical zones: we may be suspicious of the viral infection and consequently to request serologic tests to confirm it. we get an explanation of the virus transmission during heterosexual relations by the frequent occurrence and importance of the genital manifestations, leading to consider aids as a true sexually transmitted disease. beside the classical opportunistic infections, ...19892725241

kaposi's sarcoma: a light and electron microscopic study.a patient with diabetes mellitus who developed the typical classic lesions of kaposi's sarcoma is described. our patient presented with a reddish-purple papulonodular lesion on the right foot of five months' duration. a skin biopsy specimen showed a proliferation of spindle cells forming numerous vascular slits and a diffuse extravasation of erythrocytes. the patient's sera was negative for human immunodeficiency virus (hiv) antibodies and cytomegalovirus (cmv) antibodies. ultrastructural examin ...19902229644
therapeutic approaches to neoplasms in aids.the multifactorial etiology of kaposi's sarcoma (ks), which is seen primarily in men, includes genetic predisposition and immunosuppression. recently, the ks seen in association with human immunodeficiency virus (hiv) infection has been shown to be mediated by the production of certain growth factors. hiv per se may also play an etiologic role via its tat gene. therapeutic options include irradiation for local or cosmetic control, interferon-alpha, combinations of antiretroviral agents and inter ...19902237135
upper airway obstruction due to tonsillar lymphadenopathy in human immunodeficiency virus infection.head and neck manifestations of human immunodeficiency virus (hiv) infection are common and include diffuse cervical lymphadenopathy, cutaneous and mucosal kaposi's sarcoma, mucosal herpes simplex infection, upper aerodigestivetractcandidiasis, and parotidlymphadenopathy and cysts. recurrent otitis media and chronic sinusitis have been noted in the pediatric hiv population. we describe a patient with hiv-associated tonsillar and adenoid lymphadenopathy and upper airway obstruction. pathologic an ...19902340129
infection of the heart by the human immunodeficiency virus.heart muscle disease in the acquired immune deficiency syndrome (aids), characterized by electrocardiographic changes or congestive cardiomyopathy, is a documented clinical problem, but its pathogenesis is obscure. in aids the heart is known to be involved by a variety of opportunistic infections as well as kaposi's sarcoma, but no causative relation with the development of cardiomyopathy has been established. this study reports evidence for direct infection of the heart in aids, not by an oppor ...19902371952
approaches to interferon combination therapy in the treatment of aids.high-dose interferon alfa (ifn alfa) therapy induces an overall response rate of 25% to 30% in unselected patients with acquired immunodeficiency syndrome (aids)-related kaposi's sarcoma. up to 50% of patients with relatively preserved immune reactivity respond to treatment. however, when dosages of 20 x 10(6) units or more per day are used to induce responses, constitutional and hematologic side effects may be significant. therefore, efforts are being made to lower the effective dose of ifn alf ...19902405490
predictive value of cd4 lymphocyte numbers for the development of opportunistic infections and malignancies in hiv-infected persons.infection with the human immunodeficiency virus (hiv) results in progressive depletion of the cd4 subset t-lymphocytes and the development of opportunistic infections and certain malignancies. charts were reviewed for 185 hiv-infected individuals with 265 aids-defining illnesses (adis) who had t-lymphocyte subset analyses performed within 2 months prior to or 1 month following the diagnosis. also included were 22 hiv-infected patients with oral candidiasis and 20 with asymptomatic infection. sig ...19911677419
hypothyroidism due to destruction of the thyroid by kaposi's sarcoma.a case of hypothyroidism that manifested as depression and deteriorating functional status and that ultimately resulted in the death of a 41-year-old patient with aids is described. postmortem examination revealed destruction of the thyroid gland by kaposi's sarcoma. analysis of stored serum samples revealed that the patient had become profoundly hypothyroid during his terminal illness. practitioners are reminded of the need to exclude metabolic causes when treating encephalopathy in patients in ...19911962092
experience with rehabilitation in the acquired immunodeficiency syndrome.patients with the acquired immunodeficiency syndrome (aids) represent a novel referral population for rehabilitation services. limited information about the rehabilitation needs of individuals with human immunodeficiency virus infection is available. we reviewed 51 consecutive patients with aids referred to a rehabilitation consult service. common problems encountered included generalized deconditioning (27%) and neurologic dysfunction (45%). neurologic presentations were diverse and included he ...19911878178
the interferons. mechanisms of action and clinical applications.the interferons (ifn) are one of the body's natural defensive responses to such foreign components as microbes, tumors, and antigens. the ifn response begins with the production of the ifn proteins (alpha, beta, and gamma), which then induce the antiviral, antimicrobial, antitumor, and immunomodulatory actions of ifn. recent advances have led to food and drug administration approval of five clinical indications for ifn. interferon alfa is approved for hairy-cell leukemia, condyloma acuminatum, k ...19911715409
granulomatous vasculitis occurring after cutaneous herpes zoster despite absence of viral genome.granuloma annulare, sarcoidal and other granulomatous dermatitides, pseudolymphoma, lymphoplasmacytoid lymphoma, and kaposi's sarcoma have been described as sequelae of herpes zoster. we report a new postzoster reaction, granulomatous vasculitis, that caused flat-topped papules restricted to the affected dermatome. polymerase chain reaction failed to detect varicella-zoster virus in a biopsy specimen. these results suggest that granulomatous vasculitis occurs without persistence of the viral gen ...19911648109
pathogenesis of hiv-related malignancies.human immunodeficiency virus (hiv)-1 infection is associated with increased frequency of kaposi's sarcoma and high-grade b-cell lymphoma. several other cancers in hiv-1-infected individuals have been reported, although without statistically significant increase in their respective occurrences. although hiv-1 does not infect either kaposi's sarcoma-derived spindle cells or b lymphocytes in vivo, viral proteins in vitro have been shown to be mitogenic to both kaposi's sarcoma-derived spindle cells ...19911751580

kaposi's sarcoma in a child after autologous bone marrow transplantation for non-hodgkin's lymphoma.a case of kaposi's sarcoma in a child with no serologic evidence of human immunodeficiency virus (hiv) infection is reported. a 7-year-old boy with stage iv non-hodgkin's lymphoma, after conventional chemotherapy, underwent autologous bone marrow transplantation (abmt). five months later he presented with supraclavicular mass and mediastinal enlargement. a bone marrow biopsy showed hypoplasia with no signs of the underlying disease, whereas the excised mass revealed a typical histologic pattern ...19911873788
hiv-related malignancies.since the recognition of kaposi's sarcoma as a manifestation of the acquired immunodeficiency syndrome, subsequent malignancies such as non-hodgkin's b-cell lymphoma and primary central nervous system lymphoma have been found to be associated with individuals infected with the human immunodeficiency virus (hiv). the epidemiology, clinical manifestations, and current concepts of pathogenesis are reviewed in this article. in addition, the relation between hiv and other malignancies, including hodg ...19911873928
adverse virus-drug interactions.over the last 3 decades, epidemiologists and clinicians have identified a few clinical entities that appear to result when a viral infection and a chemical exposure overlap and interact. ampicillin rash during infectious mononucleosis, reye's syndrome following salicylate ingestion and certain viral infections, and the association of aids-related kaposi's sarcoma with abuse of nitrite inhalants and infection due to human immunodeficiency virus are examples of such phenomena. preclinical research ...19911925290
human immunodeficiency virus-related lymphoma. prognostic factors predictive of survival.in an attempt to determine factors predictive of survival in patients seropositive for human immunodeficiency virus (hiv) with acquired immune deficiency syndrome (aids)-related lymphoma, the authors studied 60 such patients, all of whom were treated with curative intent. eleven patients presented with lymphoma primary to the brain (p-cns); the remaining 49 had systemic aids-related lymphoma. patients with p-cns lymphoma had more severe underlying hiv-related disease than did patients with syste ...19911933784
gastric adenocarcinoma associated with human immunodeficiency virus (hiv) infection.gastric adenocarcinoma developed in a 33-year-old homosexual man with human immunodeficiency virus (hiv) infection. this type of cancer is very rare in a man of his young age and in the absence of other factors. the tumor was aggressive and led to rapid death. whereas kaposi's sarcoma and lymphomas have been associated with hiv, there are only a few documented cases of adenocarcinoma associated with a suppressed immune system. the association between hiv infection and the virulence of this tumor ...19911938507
urological manifestations of hiv-related disease. a case of aids-associated testicular seminoma, kaposi's sarcoma and possible intracranial lymphoma.a wide variety of pathologies afflicting the genitourinary tract can be displayed by patients infected with the human immunodeficiency virus (hiv), including both infective and neoplastic conditions. treatment can often be offered for such conditions using a combination of therapeutic approaches. these conditions should be looked for specifically in patients with hiv infection as treatment may improve their quality of life. a case is presented of a testicular seminoma (appearing in association w ...19912004234
pancreatic involvement in human immunodeficiency virus infection.involvement of the pancreas by human immunodeficiency virus (hiv) infection has not been adequately addressed and is the object of this review. i analyzed the english language literature, including single case reports of pancreatic involvement and larger series reporting detailed pathological findings of patients with hiv infection. nonspecific pathological changes in the pancreas are frequently seen at autopsy of hiv-infected patients, but are not more common than in controls. several types of ...19912007747
characterization of long-term survivors of acquired immunodeficiency syndrome. the long-term survivor collaborative study group.of 4,073 reported patients diagnosed with aids from 1978 through 1983, 821 (20%) were not reported to be dead by january 1987. of these apparent long-term survivors, 780 (95%) were reported from 14 states or from local areas where collaborating health departments conducted special follow-up investigations: 119 (15%) were found to be alive, 475 (61%) were dead, and 186 (24%) were lost to follow-up. health departments obtained consent to collect additional clinical and laboratory information on 48 ...19912007973
granulocyte-macrophage colony-stimulating factor mitigates the neutropenia of combined interferon alfa and zidovudine treatment of acquired immune deficiency syndrome-associated kaposi's sarcoma.the combined use of zidovudine (zdv) and interferon (ifn) alfa-2a has been shown to have antiretroviral and antitumor potential benefit in the treatment of acquired immune deficiency syndrome (aids)-associated kaposi's sarcoma (ks). however, the clinical use of this combination is frequently complicated by the overlapping myelotoxicity of these agents. we report here the results of a phase i/ii study in which granulocyte-macrophage colony-stimulating factor (gm-csf) was used for those ks patient ...19912016623
antiretroviral therapy and immunomodulators in patients with aids.a number of studies have illustrated the effectiveness of hematopoietic growth factors in managing treatment-related cytopenias in patients with human immunodeficiency virus (hiv) infection. one of these factors, granulocyte-macrophage colony-stimulating factor, has been shown to restore absolute neutrophil counts in patients with acquired immunodeficiency syndrome (aids) and kaposi's sarcoma receiving a combination of zidovudine (azt) and interferon alfa. a combination of granulocyte colony-sti ...19912018046
pathogenesis of aids-associated kaposi's sarcoma.kaposi's sarcoma (ks) is a mesenchymal tumor of unclear etiopathogenesis. the epidemic form of ks occurs in up to 30% of hiv-infected individuals with lesions that have mixed cellularity, spindle cell proliferation, and neoangiogenesis. although not completely defined, the spindle cells, thought to be the tumor cells of ks, are of mesenchymal cell origin, with features resembling endothelial and smooth muscle cells. the establishment of in vitro and in vivo model systems (aids-ks cell culture an ...19912022594
oral kaposi's sarcoma in a woman as a first indication of hiv infection.although kaposi's sarcoma has been well described in homosexual men at risk for infection with the human immunodeficiency virus, there have been fewer reports of ks in women, and most of these have been in women who became infected with hiv through intravenous drug use. this report describes a woman who had no history of intravenous drug use in whom intraoral ks and hairy leukoplakia were the first indication of her infection with hiv.19912022789

oral signs and symptoms in 160 greek hiv-infected patients.one hundred and sixty hiv-infected greek patients were prospectively examined and the oral signs and symptoms were recorded. at the time of oral examination, 76 patients were asymptomatic seropositive, 47 were in arc stage and 37 had aids. one or more oral findings were recorded in 90.6% of the patients while a total of 33 different lesions were observed. the more common oral lesions (highly suspicious) were candidiasis (61%), hairy leukoplakia (24%), periodontitis (19%), necrotizing gingivitis ...19921316436
inhibition of development of kaposi's sarcoma-related lesions by a bacterial cell wall complex.in vitro and in vivo model systems for the study of human immunodeficiency virus (hiv)-associated kaposi's sarcoma (ks) were used to evaluate compounds for their potential as therapeutic agents. a sulfated polysaccharide-peptidoglycan compound (sp-pg) produced by bacteria controlled the in vitro growth of acquired immunodeficiency syndrome (aids)-associated, ks-derived spindle-shaped cells (aids-ks cells) at noncytotoxic concentrations. angiogenesis induced by aids-ks cells in the chicken chorio ...19921371891
immunologic markers of progression to acquired immunodeficiency syndrome are time-dependent and illness-specific.since prevalent cohorts may be biased by the duration of human immunodeficiency virus (hiv) infection (onset bias), it is useful to assess the potential predictive value of markers in incident cohorts of hiv-positive subjects for whom the date of seroconversion is known or can reliably be estimated. of 131 homosexual men with hiv-1 seroconversion from new york city and washington, dc, who were evaluated annually beginning in 1982, 60 developed acquired immunodeficiency syndrome (aids) by the end ...19921384311
effects of cytokines from activated immune cells on vascular cell growth and hiv-1 gene expression. implications for aids-kaposi's sarcoma pathogenesis.kaposi's sarcoma (ks) arises more frequently in homosexual and bisexual men than in other groups of hiv-1 infected individuals. clinico-epidemiologic data indicate that homosexuals often are infected with multiple microbial agents and/or subjected to other antigenic stimuli, preceding or accompanying hiv-1 infection. signs of immune activation, in fact, frequently have been detected in these individuals, and the onset of ks can precede any sign of immunodeficiency. these data have suggested that ...19921431144
recognizing the oral manifestations of aids.the first sign of hiv infection may be an unusual or rapidly progressive condition of the oral cavity, including malignancies such as kaposi's sarcoma. early diagnosis of these oral conditions can lead to early diagnosis of hiv infection and subsequent treatment with antiretroviral agents that may improve the prognosis. this illustrated review outlines the presenting signs and symptoms of the most common oral manifestations of the aids virus, including hairy leukoplakia, candidiasis, kaposi's sa ...19921449978
hiv disease and aids in women: current knowledge and a research agenda.the study of the clinical manifestations, progression, and outcome of human immunodeficiency virus (hiv) infection in women has begun in earnest. aids-defining diseases that are more common in women than in men include wasting syndrome, esophageal candidiasis, and herpes simplex virus disease, whereas kaposi's sarcoma is rare. non-aids-defining gynecological conditions such as vaginal candida infections and cervical pathology are prevalent among women at all stages of hiv infection. associations ...19921453325
human immunodeficiency virus as a risk factor in miscellaneous cancers.the association of malignancies, such as non-hodgkin's lymphoma and kaposi's sarcoma, with human immunodeficiency virus infection has been recognized since the beginning of the epidemic. however, an increasing number of tumors not diagnostic of acquired immunodeficiency syndrome has been described in this setting. taking into consideration that survival of patients with human immunodeficiency virus infection is increasing because of improvement of supportive care and better control of human immu ...19921457506
