| rapid diagnosis of acute eosinophilic pneumonia (aep) in a patient with respiratory failure using bronchoalveolar lavage (bal) with calcofluor white (cw) staining. | a diagnosis of exclusion, acute eosinophilic pneumonia (aep) is an acute febrile illness with respiratory impairment, diffuse pulmonary infiltrates, and bronchoalveolar lavage (bal) fluid eosinophilia. whether pulmonary eosinophilia in aep is primary or secondary remains undetermined. we report here a 22-year-old auto mechanic with severe aep and acute respiratory failure who required intubation and ventilatory support. the patient's bronchoalveolar lavage (bal) fluid was analyzed using cultures ... | 1997 | 9219061 |
| survival of adults with aids in the united kingdom. | accurate estimates of expected survival times and survival rates of aids patients are important both for estimating the prognosis of individuals and for monitoring the progress of the hiv/aids epidemic as new treatments are introduced. they are also needed for projecting future numbers of aids cases. data on reported aids cases held at the phls aids centre at the communicable disease surveillance centre and the scottish centre for infection and environmental health confirmed the time, age, and r ... | 1997 | 9219423 |
| aseptic meningitis from trimethoprim-sulfamethoxazole in an hiv-infected adolescent. | adolescents infected with the human immunodeficiency virus (hiv) often confront the clinician with difficult medical problems. besides the host of opportunistic infections, which can affect these patients, side effects from medications can be frequent and, at times, life-threatening. we report a case of aseptic meningitis secondary to trimethoprim-sulfamethoxazole therapy for prophylaxis against pneumocystis carinii in an hiv-infected adolescent. | 1997 | 9220510 |
| discovery of selective, small-molecule inhibitors of rna complexes--ii. self-splicing group i intron ribozyme. | self-splicing group i intron rna was chosen as a potential therapeutic target for small-molecule intervention. high-throughput screening methodologies have been developed to identify small organic molecules that regulate the activities of these catalytic introns. group introns derived from pathogenic pneumocystis carinii and phage t4 were used as model systems. inhibitors identified from a library of approximately equal to 150,000 compounds were shown to regulate biochemical reactions including ... | 1997 | 9222512 |
| impact of treatment changes on the interpretation of the concorde trial. | the concorde trial compared two policies of therapy with zidovudine (zvd) in individuals with asymptomatic hiv infection: immediate or deferred zdv. participants in both groups could stop their blinded trial therapy for several reasons and/or could start open-label zdv. the difference in survival and disease progression between the two groups was estimated allowing for treatment changes. | 1997 | 9223734 |
| fulminant pneumocystis carinii pneumonia in 4 patients with dermatomyositis. | between 1989 and 1996, 4 cases of pneumocystis carinii pneumonia (pcp) were observed in patients seronegative for the human immunodeficiency virus who were receiving corticosteroid therapy for dermatomyositis in our institution. these cases were considered unusual in light of the short delay of their onset after initiation of immunosuppressive therapy and their fulminant course: 3 of these patients died of pcp occurring during the first month of treatment with prednisone. in all 4 patients lymph ... | 1997 | 9224230 |
| opportunistic infections and psychosocial stress in hiv. | persons infected with the human immunodeficiency virus (hiv) are susceptible to both opportunistic infections and psychosocial crises at varying stages of their disease. many interventions, including lifestyle changes and chemoprophylaxis, may help prevent, delay or lessen the extent of the morbidities associated with immunodeficiency. in appropriate patients, prophylaxis for infections with pneumocystis carinii, mycobacterium avium complex and toxoplasma helps to reduce morbidity. | 1997 | 9225668 |
| extrapulmonary pneumocystosis. | extrapulmonary pneumocystosis is an exceedingly rare complication of pneumocystis carinii pneumonia (pcp). prior to the advent of the human immunodeficiency virus type 1 (hiv-1) epidemic, only 16 cases of extrapulmonary pneumocystosis in individuals who were immunocompromised by a variety of underlying diseases had been reported. since the beginning of the hiv-1 and related pcp epidemic, at least 90 cases of extrapulmonary pneumocystosis have been reported. this review briefly presents a history ... | 1997 | 9227859 |
| the activity of triple combinations of antifolate biguanides, with and without folinic acid, against plasmodium falciparum in vitro. | at least two triple combinations of biguanides, proguanil-atovaquone-dapsone and ps-15-atovaquone-dapsone, may be useful in treating drug-resistant infections of falciparum malaria. each of these triple combinations can be considered as two synergistic combinations: proguanil-atovaquone and cycloguanil-dapsone, and ps-15-atovaquone and wr99210-dapsone, respectively. since folinic acid might mitigate the possible side-effects produced by such drug combinations, both combinations were administered ... | 1997 | 9229018 |
| temporal trends and factors associated with survival after pneumocystis carinii pneumonia in california, 1983-1992. | the authors investigated quarterly trends in survival after the diagnosis of pneumocystis carinii pneumonia for 19,607 patients in california in the decade from january 1, 1983, through december 31, 1992. subjects included all cases for whom p. carinii pneumonia was the initial (and only) acquired immunodeficiency syndrome (aids)-defining diagnosis as reported to the california human immunodeficiency virus/aids surveillance registry. there was a period of rapidly improving survival from approxim ... | 1997 | 9230773 |
| pneumocystis carinii pneumonia in malawian children. | sixty children aged between 1 and 23 months admitted to queen elizabeth central hospital in blantyre, malawi for diagnosis of acute lower respiratory tract infections (alri) were investigated for laboratory diagnosis of pneumocystis carinii pneumonia (pcp) by indirect immunofluorescence assay on nasopharyngeal secretions. p. carinii was found in five of the 60 children. three pcp cases had aids. the clinical presentation of children with pcp was of little diagnostic value and all the children we ... | 1997 | 9230974 |
| care for the patient with aids in the icu: outcomes and ethics. | hiv infection and aids are common diagnoses in many intensive care units (icus) in the united states. although pneumocystis carinii currently represents only one quarter of all diagnoses for which hiv-infected persons are admitted to the icu, it is the disease with the most clinically applicable outcome data and, therefore, is a model for ethical decision-making regarding patients with hiv infection in the icu. despite advances in diagnosis and treatment of hiv-related p. carinii, recent studies ... | 1997 | 9233138 |
| [pulmonary alveolar proteinosis: ultrastructural study of 4 cases]. | pulmonary alveolar proteinosis (pap) is a rare and diffuse lung disease characterized by the abnormal deposition of pas positive, lipoproteinaceous material in the alveolar spaces. it has been related, mainly, to alterations in the immune state and to secondary infections. we studied four cases of pap diagnosed by light microscopy. in two cases we were able to demonstrate disseminated histoplasmosis related to immunodeficiency states (aids and malnutrition), one case with pneumocystis carinii in ... | 1997 | 9235071 |
| [radiographic findings in pneumocystis carinii pneumonia and its complications in hiv patients]. | we have performed a retrospective study of 61 cases of pneumocystis carinii pneumonia (pcp) among the human immunodeficiency virus (hiv) seropositive population at the 11th health area of the comunidad de madrid with microbiological diagnosis until january 1994. we made an epidemiologic analysis of this pcp group and compared it with the epidemiologic data of the general hiv population in madrid. besides, we studied the radiologic manifestations and their possible associations with several facto ... | 1997 | 9235078 |
| infection and pathogenicity of chimeric simian-human immunodeficiency viruses in macaques: determinants of high virus loads and cd4 cell killing. | chimeric simian-human immunodeficiency viruses (shivs) carrying envelope glycoproteins derived from a t cell-macrophage dual-tropic primary isolate (human immunodeficiency virus type 1 [hiv-1] strain dh12) were constructed. when inoculated into macaque monkeys, shiv(md14) carrying simian immunodeficiency virus-derived nef established significantly higher virus loads than did shiv(md1), which contains the hiv-1 nef gene. three patterns of cd4 cell depletion were observed in infected monkeys: expo ... | 1997 | 9237701 |
| [extrapulmonary and disseminated pneumocystosis in aids. a review of the literature]. | we present a literature review about extrapulmonary and disseminated pneumocystosis in aids. the prevalence of such infections seems low but is probably under-estimated. disseminated pneumocystosis occurs in patients with profound immunosuppression, who do not receive prophylaxis against pneumocystis carinii pneumonia or are treated with aerolized pentamidine. the lack of specificity of symptoms may delay the diagnosis. most organs may be involved. three different presentations may be individual ... | 1997 | 9238445 |
| cd8+ t lymphocyte counts as an adjunctive predictor of cytomegalovirus retinitis in patients with acquired immunodeficiency syndrome. | we encountered a case of cytomegalovirus (cmv) retinitis with spontaneous regression in association with an increased number of cd8+ but not cd4+ t lymphocytes in a patient with acquired immunodeficiency syndrome (aids). thus, we examined the number of cd4 and cd8 counts at the diagnosis of cmv retinitis and compared with those of pneumocystis carinii pneumonia (pcp). all 21 patients with a confirmed diagnosis of pcp (22 episodes) and 14 cmv retinitis patients were included in this study. althou ... | 1997 | 9240493 |

| epidemiology of hiv/aids in women and children in the usa. | in the usa, the aids epidemic has shown dramatic increases among women and children in the past decade with more than 70,000 cases in women and 7000 cases in children reported. acquired immunodeficiency syndrome is the seventh leading cause of death in children aged 1-4 years and the fourth leading cause of death among women aged 25-44 years. data from the national survey of childbearing women, a blinded serosurvey of blood specimens left over from routine metabolic screening of most infants bor ... | 1997 | 9240851 |
| meta-analysis of prophylactic treatments against pneumocystis carinii pneumonia and toxoplasma encephalitis in hiv-infected patients. | in a meta-analysis, we examined the efficacy of aerosolized pentamidine, trimethoprim-sulfamethoxazole, and dapsone or dapsone/pyrimethamine for the prevention of pneumocystis carinii pneumonia and toxoplasma encephalitis in patients with hiv infection. of 22 trials, 13 compared trimethoprim-sulfamethoxazole with aerosolized pentamidine, nine compared dapsone alone or in combination with pyrimethamine with aerosolized pentamidine, and eight compared trimethoprim-sulfamethoxazole with dapsone/pyr ... | 1997 | 9241108 |
| central nervous system pneumocystosis in a patient with aids. | extrapulmonary involvement with pneumocystis carinii has been described in 0.5%-2.5% of persons with aids. one hundred nine patients with aids and confirmed extrapulmonary pneumocystosis were identified, and seven of these patients (including our patients) had central nervous system (cns) pneumocystosis. of these seven patients, six had prior aids-related complications, and three had previous p. carinii pneumonia. six patients had cns symptoms, one of whom underwent a focal neurological examinat ... | 1997 | 9243039 |
| a pneumocystis carinii multi-gene family with homology to subtilisin-like serine proteases. | copies of multi-gene family, named prt1 (protease 1), encoding a subtilisin-like serine protease were cloned from the opportunistic fungal pathogen pneumocystis carinii. comparison of the nucleotide sequence of a genomic clone and a cdna clone of prt1 from p. carinii f. sp. carinii revealed the presence of seven short introns. several different domains were predicted from the deduced amino acid sequence: an n-terminal hydrophobic signal sequence, a pro-domain, a subtilisin-like catalytic domain, ... | 1997 | 9245811 |
| steady-state effects of vitronectin and fibronectin on the binding, uptake, and degradation of pneumocystis carinii in rat alveolar macrophages. | pneumocystis carinii pneumonia remains a serious complication of immunodeficiency. vitronectin (vn) and fibronectin (fn) accumulate in the lung during p. carinii infection and bind to the organism, thereby enhancing macrophage release of tnf alpha. it is not known whether vn and fn also regulate uptake and degradation of p. carinii by macrophage when present in concentrations similar to those in the lung during pneumonia. to address this, macrophages were cultured with 35s-radiolabeled p. carini ... | 1997 | 9246575 |
| understanding the devastation of aids. | a patient admitted to your unit this morning presents a dauntingly complex clinical picture. maria dejesus, 34 years old, has hiv infection, which progressed to aids last year with an episode of pneumocystis carinii pneumonia. she's also experienced recurrent vaginal and esophageal candidiasis and cryptococcal meningitis, and her more recent history includes peripheral neuropathy, causing pain and numbness, as well as cognitive and motor function problems. her admission was prompted by diarrhea ... | 1997 | 9247379 |
| penetration of dapsone into cerebrospinal fluid of patients with aids. | it has been proposed that dapsone in combination with pyrimethamine could be used for prophylaxis of both pneumocystis carinii pneumonia and encephalitis due to toxoplasma gondii. ten patients with aids undergoing lumbar puncture for diagnostic purposes were studied in order to assess the penetration of dapsone into csf. blood and csf samples were obtained between 3 and 72 h following administration. six patients had received oral dapsone for at least 1 month at the dosage regimen of 100 mg twic ... | 1997 | 9249213 |
| predicting in-hospital mortality of patients with aids-related pneumocystis carinii pneumonia: an example of hierarchically optimal classification tree analysis. | a non-linear statistical classification methodology known as hierarchically optimal classification tree analysis (cta) offers promise of outperforming linear alternatives. we present the first example of cta in medicine, for an application that uses four attributes (age, body mass index, alveolar-arterial oxygen gradient, prior history of aids) to predict in-hospital mortality for a sample of 1339 patients with aids-related pneumocystis carinii pneumonia. we also illustrate use of a hold-out (cr ... | 1997 | 9249918 |
| the results of direct and indirect treatment comparisons in meta-analysis of randomized controlled trials. | when little or no data directly comparing two treatments are available, investigators often rely on indirect comparisons from studies testing the treatments against a control or placebo. one approach to indirect comparison is to pool findings from the active treatment arms of the original controlled trials. this approach offers no advantage over a comparison of observational study data and is prone to bias. we present an alternative model that evaluates the differences between treatment and plac ... | 1997 | 9250266 |
| pneumocystis carinii cysts are susceptible to inactivation by chemical disinfectants. | the inactivation efficacy of eight disinfectants commonly used in laboratories and animal rooms to inactive pneumocystis carinii cysts was estimated by experimental infection in c.b-17-scid mice. the disinfectants examined in this study were 70% ethyl alcohol, 10% iodoform, 0.5% hypochlorous acid, two 1% quanternary ammonium salts, 3% hydrogen peroxide, sodium chlorite and 1% cresol soap. the lung homogenates from p. carinii infected c.b-17-scid mice were treated with each disinfectant for 15 mi ... | 1997 | 9250487 |
| late infections following allogeneic bone marrow transplantation: suggested strategies for prophylaxis. | bone marrow transplant recipients remain at risk for infections for a variable period of time even after adequate hematologic reconstitution. late infections are a significant cause of morbidity and can be fatal in 4-15% of these patients. patients with chronic graft versus host disease (gvhd) and unrelated-donor transplant recipients, even without gvhd, are at particular risk. most late infections occur in the first post-transplant year, the majority are caused by bacteria, particularly encapsu ... | 1997 | 9250782 |

| clinical spectrum of x-linked hyper-igm syndrome. | we report the clinical and immunologic features and outcome in 56 patients with x-linked hyper-igm syndrome, a disorder caused by mutations in the cd40 ligand gene. upper and lower respiratory tract infections (the latter frequently caused by pneumocystis carinii), chronic diarrhea, and liver involvement (both often associated with cryptosporidium infection) were common. many patients had chronic neutropenia associated with oral and rectal ulcers. the marked prevalence of infections caused by in ... | 1997 | 9255191 |
| defective antigen-induced lymphocyte proliferation in the x-linked hyper-igm syndrome. | we examined t-cell proliferation in five patients with x-linked hyper-igm syndrome (xhim), using a panel of antigens and lectins. all patients had impaired antigen-induced proliferation, whereas their lectin responses were normal. thus, in addition to severely depressed antibody responses, patients with xhim have a defect in antigen-specific t-cell proliferation, which may explain their susceptibility to pathogens such as pneumocystis carinii. | 1997 | 9255207 |
| [prevention of parasitic infections (excluding toxoplasmosis) in immunocompromised patients]. | immunocompromised patients, notably those with cell mediated immunity deficiency, are at risk for severe and life-threatening parasitic infections. severity and frequency of pneumocystis carinii pneumonia have led to systematically initiate prophylaxis for high-risk patients such as patients with hiv infection, hemopathy or renal transplants. cotrimoxazole has shown the best efficacy both in primary and secondary prophylaxis. side effects, notably skin rash, constitute the major limiting factor ... | 1997 | 9255333 |
| endocrine modulation of the neurotoxicity of gp120: implications for aids-related dementia complex. | hiv infection often involves the development of aids-related dementia complex, a variety of neurologic, neuropsychologic, and neuropathologic impairments. a possible contributor to aids-related dementia complex is the hiv envelope glycoprotein gp120, which damages neurons via a complex glutamate receptor- and calcium-dependent cascade. we demonstrate an endocrine modulation of the deleterious effects of gp120 in primary hippocampal and cortical cultures. specifically, we observe that gp120-induc ... | 1997 | 9256504 |
