united states aids activity.the tables in this report present data on cases reported to the centers for disease control by may 26, 1986, of acquired immunodeficiency syndrome (aids). as of that date, a total of 21,065 cases (20,771 involving adults and 294 involving children under 18 years of age) had been reported. 11,541 (55%) of aids victims have died. the majority of cases in both the adult and pediatric populations have involved pneumocystis carinii pneumonia without kaposi's sarcoma. 47% of aids cases have occurr ...198612267771
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
the global aids situation -- updated, june 1990.the global aids and hiv situation, in terms of prevalence, by region and sex, means of transmission, progress in treatment, and the tasks undertaken by the who global programme on aids are summarized as of june 1990. over 250,000 cases of aids had been reported to who from over 150 countries by mid-1990. because of under-reporting who estimates that actually 700,000 cases of aids exist. who predicts 1 million cases by 2000. 6-8 million persons with hiv are estimated, and 15-20 million are pr ...199012283394
diagnosing symptomatic hiv infection and aids in adults.the us centers for disease control in 1982 listed conditions and infections then associated with aids. that case definition, used as a model for many countries, was designed primarily for epidemiologic surveillance and now includes more than 20 conditions. the definition, however, requires diagnostic and laboratory technologies which are not always available in developing countries. the world health organization (who) therefore published the bangui definition in 1985 which uses clinical crite ...199312288934
[characteristics of human immunodeficiency virus infection in the san juan de dios general hospital].a prospective clinical study was conducted between january 1991 and june 1992 of 92 hiv seropositive patients attending the adult outpatient clinic of the san juan de dios general hospital in guatemala city. 52 of the patients met the us centers for disease control clinical criteria for aids. limitations in the diagnostic and laboratory facilities of the hospital hampered identification of some opportunistic infections. 74 of the 92 patients were male. 3 of the 18 infected women gave birth du ...199212290621
managing illness.although most infants infected with hiv manifest no symptoms of their infected status at birth, hiv-infected children usually develop clinical signs of hiv/aids much sooner after infection than do adults. a small percentage of children manifest no signs of hiv infection until reaching age 10 years or older. more than half of all hiv-infected children live for more than 5 years. it is extremely important that hiv-infected children lead normal lives, being allowed to play with friends, go to sc ...199812294836

aids and africa.this article describes the aids situation in africa and pinpoints the differences, so far as they are known, between that continent and the us and europe. there is currently evidence of infection in up to 15% of the general urban population of some african countries, although it is impossible to estimate the total number of cases. among san francisco homosexuals who are sero-positive, about 1/3 are expected to develop aids within 5 years; among infected newborns the development of aids is even ...198712340978
pneumocystis carinii pneumonia in critically ill patients with malignancy: a descriptive study.there are few data on pneumocystis carinii pneumonia (pcp) in critically ill human immunodeficiency virus (hiv)-negative patients. improved knowledge of the presenting symptoms of and prognostic factors for pcp may help to reduce the high mortality rate associated with pcp in such patients. we retrospectively studied 39 consecutive patients with acute pcp-related respiratory failure and malignancy who were treated at 2 intensive care units (icus) during a 10-year period. univariate logistic regr ...200212355379
presenting syndromes of human immunodeficiency virus.over the past 2 decades, numerous changes have occurred in the demographics and clinical course of the human immunodeficiency virus (hiv) infection. since the initial reports of mucosal candidiasis, severe weight loss, and pneumocystis carinii pneumonia as presenting manifestations of the late stages of immunodeficiency, clinicians have recognized a wide spectrum of manifestations associated with hiv disease. the original reports of severe immunodeficiency were simply the "tip of the iceberg." a ...200212374253
local delivery of the viral interleukin-10 gene suppresses tissue inflammation in murine pneumocystis carinii infection.the relationship between tissue inflammation and clearance of the opportunistic pathogen pneumocystis carinii is poorly understood. we asked whether the anti-inflammatory cytokine interleukin-10 (il-10) is released during the host response to infection with p. carinii and whether local delivery of the il-10 gene could suppress tissue inflammatory responses without compromising clearance of infection. control and cd4-depleted mice were inoculated with p. carinii, and at serial intervals after ino ...200212379687
fatal sepsis in an aids patient during therapy for pneumocystis carinii pneumonia.the case of a patient with a newly diagnosed hiv infection and pneumocystis carinii pneumonia is presented. despite treatment with high-dose trimethoprim/sulfamethoxazole (tmp/smx) and prednisone with initial improvement, the patient acutely deteriorated with severe acidosis and died on the 4th day of hospitalization. cryptococcus neoformans grew the next day in broncheoalveolar lavage (bal) and blood culture. as simultaneous presence of more than one opportunistic infection can occur in these p ...200212382094
lung diseases at necropsy in african children dying from respiratory illnesses: a descriptive necropsy study.accurate information about specific causes of death in african children dying of respiratory illnesses is scarce, and can only be obtained by autopsy. we undertook a study of children who died from respiratory diseases at university teaching hospital, lusaka, zambia.200212383668
ineffectiveness of trimethoprim-sulfamethoxazole prophylaxis and the importance of bacterial and viral coinfections in african children with pneumocystis carinii pneumonia.african human immunodeficiency virus type 1 (hiv-1)-infected children were evaluated to define the burden of pneumocystis carinii pneumonia (pcp) and its interaction with bacterial and viral pathogens. p. carinii was identified in 101 (43.7%) of 231 episodes of pneumonia among 185 hiv-1-infected children (median age, 4.5 months; range, 1.7-27.3 months). receipt of trimethoprim-sulfamethoxazole (tmp-smx) prophylaxis was not associated with a significant reduction (36%; 95% confidence interval [ci ...200212384847
[adult t-cell leukemia/lymphoma. clinical aspects].background data: adult t-cell leukemia/lymphoma (atl) is a malignant proliferation of activated cd4+ t lymphocytes. the disease is almost exclusively found in patients living in retrovirus htlv-1 endemic areas. virology: in atl, monoclonal htlv-1 provirus is integrated into atypical lymphocytes, called clover-leaf lymphocytes. the pathogenic mechanism leading to htlv-1-induced leukemogenesis remains obscure. the disease generally occurs after a long latency period. four clinical subtypes: the di ...200112385062

diagnosis of diffuse cd8+ lymphocytosis syndrome in hiv-infected patients.the diffuse infiltrative lymphocytosis syndrome (dils) in hiv-infected persons is characterized by a persistent circulating cd8+ lymphocytosis. certain hiv-infected persons appear to respond to their infection by developing an oligoclonal expansion of cd8+ lymphocytes. these cells infiltrate multiple organs, but the salivary glands and the lung constitute the major sites involved in this process. this infiltrative process resembles in many aspects a sjögren-like syndrome, owing to the visceral l ...200212402804
surveillance for aids-defining opportunistic illnesses, 1992-1997.acquired immunodeficiency syndrome (aids)-defining opportunistic illnesses (ois) are the major cause of morbidity and mortality among persons infected with human immunodeficiency virus (hiv). as a result of new treatments that reduce mortality for persons with aids, the number of persons living with aids is increasing, and the incidence of aids is decreasing. in 1997, an estimated 271,245 persons were living with aids in the united states and thus were at high risk for ois. in 1997, an estimated ...199912412613
meta-analysis of diagnostic procedures for pneumocystis carinii pneumonia in hiv-1-infected patients.sputum induction is a simple and noninvasive procedure for pneumocystis carinii pneumonia (pcp) diagnosis in human immunodeficiency virus-1-positive patients, although less sensitive than bronchoalveolar lavage (bal). in order to obtain an overview of the diagnostic accuracy of sputum induction, a systematic review and meta-analysis of studies reporting the comparative sensitivity and specificity of bal (the "gold standard") and sputum induction was performed. the odds ratio and related 95% conf ...200212412693
aids-related pneumocystis carinii pneumonia with disappearance of cystic lesions after treatment.a 21-year-old hemophiliac with human immunodeficiency virus (hiv) infection was admitted to our hospital because of bilateral pneumothoraces associated with pneumocysis carinii pneumonia (pcp). he underwent chest tube drainages and intravenous pentamidine therapy, resulting in clinical improvement. two months after treatment for pcp, cystic lesions that had existed before treatment disappeared on chest computed tomography. we concluded that pneumocystis carinii infection might be associated with ...200212413019
pneumocystis carinii in a patient with hypercalcemia and renal failure secondary to sarcoidosis.a case of severe dyspnea, hypercalcemia and renal failure secondary to sarcoidosis is reported. the clinical diagnosis of sarcoidosis in a 48-year-old man was confirmed by histology and cytology. transiently decreased numbers of cd4+ t cells (282/microliter) indicated impaired immunity in the absence of hiv-infection during the acute phase of the disease. surprisingly, numerous "trophozoites" of pneumocystis carinii were detected by immunofluorescence staining and pcr in the bronchoalveolar flui ...200212416284
pneumocystis carinii cell wall beta-glucan induces release of macrophage inflammatory protein-2 from alveolar epithelial cells via a lactosylceramide-mediated mechanism.infiltration of the lungs with neutrophils promotes respiratory failure during severe pneumocystis carinii (pc) pneumonia. recent studies have shown that alveolar epithelial cells (aecs), in addition to promoting pc attachment, also participate in lung inflammation by the release of cytokines and chemokines. herein, we demonstrate that a pc beta-glucan rich cell wall isolate (pcbg) stimulates the release of macrophage inflammatory protein-2 (mip-2) from isolated aecs through a lactosylceramide-d ...200312419803

surfactant improves oxygenation in infants and children with pneumonia and acute respiratory distress syndrome.pneumonia in childhood may be associated with surfactant dysfunction and severe acute respiratory distress syndrome (ards). the aim of this study was to investigate the effects of surfactant treatment on oxygenation in 8 infants (age range: 1 mo to 13 y) with severe respiratory failure owing to viral, bacterial or pneumocystis carinii pneumonia.200212463314
synthesis of new 2,4-diaminopyrido[2,3-d]pyrimidine and 2,4-diaminopyrrolo[2,3-d]pyrimidine inhibitors of pneumocystis carinii, toxoplasma gondii, and mycobacterium avium dihydrofolate reductase.a concise new route allowing easy access to five previously unreported 2,4-diamino-6-(substituted benzyl)pyrido[2,3-d]pyrimidines (2a-e) was developed, involving condensation of 2,4-dipivaloylamino-5-bromopyrido[2,3-d]pyrimidine (6) with an organozinc halide in the presence of a catalytic amount of [1,1'-bis(diphenylphosphino)ferrocene]dichloropalladium(ii).ch(2)cl(2), followed by removal of the pivaloyl groups with base. also prepared via a scheme based on the taylor ring expansion/ring annulat ...200312467708
lethal t cell immunodeficiency induced by chronic costimulation via cd27-cd70 interactions.it has been proposed that hiv-1, in addition to directly infecting and killing cd4+ t cells, causes t cell dysfunction and t cell loss by chronic immune activation. we analyzed the effects of chronic immune activation in mice that constitutively expressed cd70, the ligand for the tumor necrosis factor receptor family member cd27, on b cells. cd70 transgenic (cd70 tg) mice showed a progressive conversion of naive t cells into effector-memory cells, which culminated in the depletion of naive t cel ...200312469117
evidence for the requirement of t cell costimulation in the pathogenesis of natural pneumocystis carinii pulmonary infection.pneumocystis carinii pneumonia (pcp) is a frequent and serious opportunistic infection in immunocompromized patients. although the pathogenesis of pcp-mediated lung injury is poorly understood, a central involvement of host inflammatory responses has been implicated. we have found that while the loss of specific t cell costimulatory signals increases susceptibility to the spontaneous pneumocystis infection, pcp-induced pulmonary injury (and subsequent morbidity and mortality) involves other inta ...200212473434
[pneumocystis carinii pneumonia in patients without acquired immunodeficiency syndrome (aids)].the incidence of pneumocystis carinii pneumonia (pcp) may rise due to a more extensive use of immunosuppressive therapy. information and guidelines in the last decade regarding prevention, diagnosis and treatment of the disease were based upon data collected in patients with acquired immuno deficiency syndrome (aids). however, scientific data regarding risk factors, clinical manifestations and treatment of pcp in patients without aids is accumulating. the major risk factors for acquiring pcp are ...200212476635
pneumocystis carinii pneumonia in a patient with stage iv ovarian cancer.immunocompromised persons are considered to be at risk of developing pneumocystis carinii pneumonia, although the incidence of this condition is much lower compared to the human immunodeficiency virus-positive group. it is important to identify specific individuals at high clinical risk to guide the chemoprophylaxis of p. carinii pneumonia.200212477458
improved survival with highly active antiretroviral therapy in hiv-infected patients with severe pneumocystis carinii pneumonia.although the incidence of pneumonia (pcp) has declined, mortality of patients who require intensive care for this disease remains high. highly active antiretroviral therapy (haart) might alter the course of pcp either via effects on the immune system or through anti- actions; however, haart has not been studied in patients acutely ill with pcp.200312478071

ribozyme-catalyzed excision of targeted sequences from within rnas.we demonstrate that a group i intron-derived ribozyme from the opportunistic pathogen pneumocystis carinii can bind an rna in trans and excise from within it an internal segment, resulting in the splicing of the remaining ends of the rna back together (the trans excision-splicing reaction). the reaction is intramolecular with regard to substrate. the ribozyme targets its substrate by base pairing with two or three noncontiguous regions on the substrate, and the reaction occurs through a nucleoti ...200212484771
rituximab for refractory childhood autoimmune hemolytic anemia.chronic childhood autoimmune hemolytic anemia is an uncommon disorder that is associated with significant morbidity. treatment with high dose steroids, splenectomy and frequent blood transfusions results in a myriad of complications including growth failure, bone demineralization, cushing's syndrome, immunosuppression, and transfusional hemosiderosis.200212489491
pneumocystis carinii pneumonia in patients in the developing world who have acquired immunodeficiency syndrome.we review pneumocystis carinii pneumonia (pcp) in patients in the developing world (i.e., africa, asia, the philippines, and central and south america) who have acquired immunodeficiency disease (aids). during the first decade of the aids pandemic, pcp rarely occurred in african adults. more recent reports have noted that pcp comprises a significantly greater percentage of cases of pneumonia than it did in the past. this trend dramatically contrasts with that observed in industrialized nations, ...200312491205
natural history of human immunodeficiency virus disease in southern india.there are few reports of the natural history of human immunodeficiency virus (hiv) infection from asia. in a retrospective analysis of 594 patients (72.9% male; baseline cd4 cell count, 216 cells/microl) receiving care at yrg center for aids research and education, a tertiary hiv referral center in southern india, the mean duration of survival from serodiagnosis was 92 months. ninety-three percent of the patients acquired infection through heterosexual contact. the most common acquired immune de ...200312491206

diversity at the locus associated with transcription of a variable surface antigen of pneumocystis carinii as an index of population structure and dynamics in infected rats.pneumocystis carinii expresses a surface glycoprotein called msg. different isoforms of msg are encoded by a gene family spread over at least 15 telomeric sites. only one locus, called ucs, supports the production of msg mrna. previous studies showed that p. carinii populations from individual rats exhibited high degrees of diversity with respect to the msg genes attached to the ucs locus. this diversity could have been generated primarily in the rats studied. alternatively, the rats may have be ...200312496148
a single-copy gene encodes kex1, a serine endoprotease of pneumocystis jiroveci.we have cloned and characterized the kex1 gene of pneumocystis jiroveci. unlike the case for pneumocystis carinii, in which the homologous prt-1 genes are multicopy, kex1 is a single-copy gene encoding a protein homologous to fungal serine endoproteases, which localize to the golgi apparatus. thus, substantial biological differences can be seen among pneumocystis species.200312496214
bronchiolitis obliterans and lung transplantation: evidence for an infectious etiology.bronchiolitis obliterans (ob) or bronchiolitis obliterans syndrome (bos) remains a major hurdle in the long-term survival of lung transplant recipients. the pathogenesis of ob or bos remains to be fully discerned, but it is hypothesized that allogenic or nonallogenic insults result in the release of chemokines and t lymphocytes propagating the injury and ultimately recruiting fibroblasts culminating in intraluminal proliferation. infectious agents, with or without other exogenous factors, have b ...200212497548

pneumocystis jiroveci internal transcribed spacer types in patients colonized by the fungus and in patients with pneumocystosis from the same french geographic region.pneumocystis jiroveci (human-derived pneumocystis) infections can display a broad spectrum of clinical presentations, of which pulmonary colonization with the fungus may represent an important part, occurring frequently in patients with various underlying diseases and presenting alternative diagnoses of acute pneumocystosis (pneumocystis carinii pneumonia [pcp]). there are few data concerning the p. jiroveci genotypes involved in pulmonary colonization, whereas several genotypes responsible for ...200312517845
il-10 modulates host responses and lung damage induced by pneumocystis carinii infection.host responses to pneumocystis carinii infection mediate impairment of pulmonary function and contribute to the pathogenesis of pneumonia. il-10 is known to inhibit inflammation and reduce the severity of pathology caused by a number of infectious organisms. in the present studies, il-10-deficient (il-10 knockout (ko)) mice were infected with p. carinii to determine whether the severity of pathogenesis and the efficiency of clearance of the organisms could be altered in the absence of il-10. the ...200312517967
pneumonia due to candida krusei.a case of post-transplantation pneumonia due to candida krusei is reported. a 42-year-old man was admitted 28 days after heart transplantation with cough, pleuritic pain and fever. a chest computed tomograph showed multiple alveolar infiltrates bilaterally. he received broad-spectrum antibiotics, fluconazole for oral candidiasis, and cotrimoxazole for possible pneumocystis carinii. a short-lived period of improvement was followed by respiratory failure. cultures of bronchial washings grew c. kru ...200212519355
[hiv screening in pregnancy--too many failures?].danish official guidelines recommend that women belonging to risk groups should be offered hiv testing during pregnancy. universal hiv testing during antenatal care is not required. we describe three infants with vertically acquired hiv infection born to mothers, who, despite belonging to high-risk groups (one from thailand, two from sub-saharan africa), had not been offered an hiv test during pregnancy. the infants, born within a one-year period, presented with aids-defining symptoms during the ...200212523030
the first isolation of nocardia nova from an hiv-1 infected individual in japan.nocardia species are opportunistic pathogens of immunocompromised patients. we report a case of nocardia nova infection complicating pneumocystis carinii pneumonia (pcp) in an hiv-1 infected individual. a 27-year-old man with hemophilia a was admitted on october 17, 2000, with fever and dyspnea. cd4 cell counts were 5/microl on admission. prophylaxis against pcp was administered by inhalation of pentamidine isethionate because he was allergic to sulfamethoxazole-trimethoprim (smz-tmp). he was di ...200212525899
chronic pneumocystis carinii pneumonia associated with extensive pneumatocele formation in a child with human immunodeficiency virus infection.we describe a 12-year-old boy with pneumocystis carinii pneumonia complicated by extensive pneumatocele formation as the presenting manifestation of human immunodeficiency virus infection. this report emphasizes the importance of considering pneumocystis carinii infection in the differential diagnosis of pneumonia associated with pneumatocele formation in children.200312526077
risk for pneumocystis carinii transmission among patients with pneumonia: a molecular epidemiology study.we report a molecular typing and epidemiologic analysis of pneumocystis carinii pneumonia (pcp) cases diagnosed in our geographic area from 1990 to 2000. our analysis suggests that transmission from patients with active pcp to susceptible persons caused only a few, if any, pcp cases in our setting.200312533297
follicular bronchiolitis (fbb) associated with legionella pneumophilia infection.an 8-month-old girl with respiratory distress and stridor was admitted to the authors' hospital. two days later, she died of respiratory insufficiency due to pneumonia. autopsy confirmed the presence of follicular bronchiolitis (fbb) in both lungs. after considering her clinical course, the authors focused on three pathogens: legionella pneumophilia, pneumocystis carinii, and mycobacterium tuberculosis. only legionella pneumophilia was detected by both immunohistochemistry and pcr.200212537768
prediction of dihydrofolate reductase inhibition and selectivity using computational neural networks and linear discriminant analysis.a data set of 345 dihydrofolate reductase inhibitors was used to build qsar models that correlate chemical structure and inhibition potency for three types of dihydrofolate reductase (dhfr): rat liver (rl), pneumocystis carinii (pc), and toxoplasma gondii (tg). quantitative models were built using subsets of molecular structure descriptors being analyzed by computational neural networks. neural network models were able to accurately predict log ic(50) values for the three types of dhfr to within ...200312543137
epidemiology and outcome of clostridium difficile infection and diarrhea in hiv infected inpatients.clostridium difficile causes diarrhea in hiv infected patients but reports of prevalence, risk factors, and outcome vary. we studied the impact of c. difficile in 161 hiv infected inpatients admitted to cook county hospital. patients with c. difficile had more hospital admissions in the previous 6 months (p =.04), spent more days in the hospital in the previous 3 months (p =.02), more often had previously received h2 blockers or treatment for pneumocystis carinii (p <.05), and had a more frequen ...200212543536
