| 2,4-diamino-6,7-dihydro-5h-cyclopenta[d]pyrimidine analogues of trimethoprim as inhibitors of pneumocystis carinii and toxoplasma gondii dihydrofolate reductase. | three previously unreported (r,s)-2,4-diamino-5-[(3,4,5-trimethoxyphenyl) alkyl]-6,7-dihydro-5h-cyclopenta[d]pyrimidines 15a-c were synthesized as analogues of trimethoprim (tmp) and were tested as inhibitors of pneumocystis carinii, toxoplasma gondii, and rat liver dihydrofolate reductase (dhfr). the length of the alkyl bridge between the cyclopenta[d]pyrimidine and trimethoxyphenyl moiety ranged from one in 15a to three carbons in 15c. the products were tested as competitive inhibitors of the ... | 1998 | 9526565 |
| medical management of the pregnant woman infected with human immunodeficiency virus type 1 and her child. | heterosexual contact and intravenous drug use continue to result in new cases of human immunodeficiency virus type 1 (hiv-1) infection among adolescents and women of childbearing age. in north american and european surveys, 0.1% to 0.3% of childbearing women are infected with hiv; rates are 10 to 20 times higher in some inner-city areas. timely, comprehensive, and well-coordinated care of the pregnant hiv-infected mother offers a unique opportunity to significantly influence two lives simultaneo ... | 1998 | 9523401 |
| the demography, clinical manifestations and natural history of human immunodeficiency virus (hiv) infection in an older population in singapore. | in this retrospective study, we report 43 cases (41 males and 2 females) of human immunodeficiency virus (hiv) infection in the singapore population aged 50 years and above at first presentation. we found an increasing proportion of these older individuals among our hiv-seropositive patients; from 4.8% in 1991 to 16.7% by mid-1996. the mean age at presentation was 59.2 years (range 50 to 75 years). they were mainly heterosexuals (93%) and the majority (79.1%) were previously or currently married ... | 1997 | 9522969 |
| anti-pneumocystis activities of aromatic diamidoxime prodrugs. | aromatic dicationic compounds, such as pentamidine, have potent antimicrobial activities. clinical use of these compounds has been restricted, however, by their toxicity and limited oral activity. a novel approach, using amidoxime derivatives as prodrugs, has recently been proposed to overcome these limitations. although results were presented for amidoxime derivatives of only one diamidine, pentamidine, the authors in the original proposal claimed that amidoxime derivatives would work as effect ... | 1998 | 9517949 |
| frequency and determinants of use of antiretroviral and prophylactic therapies against pneumocystis carinii pneumonia (pcp) before aids diagnosis in italy. | to determine the frequency and the determinants of use of antiretroviral drugs and prophylaxis for pneumocystis carinii pneumonia (pcp) among hiv-infected individuals before aids diagnosis, a questionnaire was sent to all physicians reporting at least one aids case during the first six months of 1994 to the italian national aids registry. information on cases diagnosed between 1 january and 31 march 1995 was collected. information was obtained for 878 (66.4%) of the 1323 persons with aids: 447 ( ... | 1998 | 9517872 |
| olecranon bursitis caused by infection with candida lusitaniae. | we describe a 59-year-old woman with diabetes and chronic asthma treated with prednisone and methotrexate who developed chronic olecranon bursitis caused by candida lusitaniae. infection, especially with unusual microbial pathogens, should be considered in cases of chronic bursitis in patients taking immunosuppressive medicine, even if the classic signs of septic bursitis are absent. infection with c. lusitaniae, a component of the normal mycoflora, may be a marker of serious immunosuppression, ... | 1998 | 9517788 |
| declining morbidity and mortality among patients with advanced human immunodeficiency virus infection. hiv outpatient study investigators. | national surveillance data show recent, marked reductions in morbidity and mortality associated with the acquired immunodeficiency syndrome (aids). to evaluate these declines, we analyzed data on 1255 patients, each of whom had at least one cd4+ count below 100 cells per cubic millimeter, who were seen at nine clinics specializing in the treatment of human immunodeficiency virus (hiv) infection in eight u.s. cities from january 1994 through june 1997. | 1998 | 9516219 |
| pneumocystis carinii in wildlife. | pneumocystis carinii is a eukaryotic organism capable of causing life-threatening pneumonia (pcp) in immunocompromised hosts. despite intensive investigation in human and laboratory animal hosts, information on the occurrence and nature of infections in wild animals is scarce, although characterisation of infections in wild-animal populations may help to elucidate the life-cycle and transmission of this elusive organism. due to the interspecific differences in prevalence and intensity of p. cari ... | 1998 | 9512987 |
| detection of pneumocystis carinii dna by pcr amplification in various rat organs in experimental pneumocystosis. | pneumocystosis is usually a disease of the lungs, but the number of cases of extrapulmonary pneumocystosis has greatly increased during the aids epidemic. much remains unknown about the frequency and mechanisms of dissemination. in the present study, a systematic search for pneumocystis carinii by pcr with primers specific for mitochondrial rrna was performed in the lung, liver, spleen and kidney of 12 immunosuppressed rats and two immunocompetent rats. the amplified products were analysed by so ... | 1997 | 9511814 |
| ubiquinone synthesis by pneumocystis carinii: incorporation of radiolabeled polyprenyl chain and benzoquinone ring precursors. | radiolabeled mevalonic acid was incorporated in vitro into pneumocystis carinii ubiquinone homologs, coq9 and coq10, demonstrating the isoprenoid branch pathway forming the polyprenyl chain of ubiquinone is functional in the organism. radiolabeled shikimic acid, tyrosine and p-hydroxybenzoic acid were also incorporated into the two ubiquinone homologs, indicating that p. carinii also possessed the biochemical pathway for de novo synthesis of the coq benzoquinone ring. | 1997 | 9508445 |

| infections in systemic lupus erythematosus patients. | infection is a frequent problem in patients with systemic lupus erythematosus (sle), especially in those hospitalised with complications of disease. infections contribute greatly to the morbidity of patients and are one of the commonest causes of death. the high frequency and unusual spectrum of infections can be attributed to the multiple disturbances of immune function in sle in combination with the effects of immunosuppressive therapy. high doses of corticosteroids are particularly implicated ... | 1997 | 9494681 |
| emerging pathogens for pneumonia in singapore. | the death rate from pneumonia in singapore has increased steadily over the past decade. the emerging respiratory pathogens may have contributed to this increased mortality. new challenges have arisen from changes in the characteristics of the host and the susceptibilities of the various pathogens to antibiotics. there has been a 60-fold increase in the incidence of penicillin resistance in streptococcus pneumoniae, the major pathogen for community-acquired pneumonia (cap). gram-negative bacilli ... | 1997 | 9494674 |
| clinical characteristics and natural history of human immunodeficiency virus infected patients seen at a general hospital in singapore. | the number of patients with human immunodeficiency virus (hiv) infection in singapore has risen over the years. a considerable proportion of them present with acquired immunodeficiency syndrome (aids). in this study, we document the clinical characteristics and natural history of a consecutive series of 50 patients who were found to have hiv infection when they were seen at a tertiary care hospital. the majority were in the 30 to 49 age group and the most common mode of acquisition was heterosex ... | 1997 | 9494659 |
| [pneumocystosis of splenic localization in the course of hiv infection: a new indication for splenectomy. description of a case]. | pneumocystis carinii is a common cause of interstitial pneumonitis in aids patients: it affects 85% of patients with cell-mediated immunodeficiencies. extrapulmonary infection is much more infrequent and it is observed only in these patients who receive aerosolized pentamidine prophylaxis because of minimal systemic distribution of the drug. no case of extrapulmonary disease was observed in patients receiving systemic prophylaxis for pneumocystis carinii with cotrimoxazole. the pathogenesis of e ... | 1997 | 9494189 |
| pneumocystis carinii contains a functional cell-division-cycle cdc2 homologue. | pneumocystis carinii causes life-threatening pneumonia in immunocompromised patients. the inability to culture p. carinii has hampered basic investigations of the organism's life cycle, limiting the development of new therapies directed against it. recent investigations indicate that p. carinii is a fungus phylogenetically related to other ascomycetes such as schizosaccharomyces pombe. the cell cycles of s. pombe and homologous fungi are carefully regulated by cell-division-cycle molecules (cdc) ... | 1998 | 9490647 |

| use of fiberoptic bronchoscopy in bone marrow transplant recipients. | bone marrow transplantation (bmt) has become the therapy of choice for a number of malignant and nonmalignant hematologic and nonhematologic disorders. a frequent complication after bmt is pulmonary disease which is associated with a high mortality rate. we examined the results of 79 bronchoscopies performed between may 1991 and may 1995 in 62 patients for the evaluation of pulmonary complications after bmt. in all cases bronchoalveolar lavage (bal) was performed, in 10% transbronchial biopsy (t ... | 1998 | 9490561 |
| [pneumocystis carinii otitis]. | background: pneumocystis carinii (pc) otitis is a rare opportunistic infection of the acquired immunodeficiency syndrome (aids). initially hearing loss and otalgia occur with thickening of the tympanic membrane and the bordering skin of the ear canal. otorrhea, ear polyps, perforation of tympanic membrane, destruction of mastoidal bone, and participation of cranial nerves are observed. diagnosis is established histologically. the treatment of the parasite is by trimethoprim-sulfamethoxazole comb ... | 1997 | 9487488 |
| pneumocystis carinii inhibits cyclin-dependent kinase activity in lung epithelial cells. | pneumocystis carinii remains an important cause of pneumonia in patients with aids. attachment of the organism to epithelial cells is a central event in establishing infection, impairing the growth potential of lung epithelial cells and thereby slowing repair. in light of investigations documenting a central role for cyclin-dependent kinases in controlling the cell cycle, we addressed the hypothesis that p. carinii inhibits epithelial cell growth by interfering with host epithelial cyclin-depend ... | 1998 | 9486986 |
| [pulmonary cryptococcosis during hiv infection. 15 cases]. | we reviewed the records of 15 human immunodeficiency virus (hiv) infected patients with pulmonary cryptococcosis (pc). pc was the first aids-defining manifestation in nine patients. hiv infection was identified simultaneously with the onset of pc in 4 patients. the cd4+ lymphocyte count was low in all cases (median, 24/m3). chest radiography showed interstitial infiltrates in 13 instances, associated with pleural effusion in 5 cases and hilar adenopathy in 2 cases. in one case, chest-x-ray showe ... | 1997 | 9480480 |
| characterization of natural occurring pneumocystis carinii pneumonia in pigs by histopathology, electron microscopy, in situ hybridization and pcr amplification. | macroscopic, histologic, ultrastructural, microbiologic, in situ hybridization (ish) and pcr detection results in three 8-week-old pigs naturally infected with pneumocystis carinii (pc) are described. all animals had a nonsuppurative interstitial pneumonia and intra-alveolar pneumocystis organisms with foamy eosinophilic and pas positive appearance. ultrastructurally, pc trophozoites and cysts were observed in pigs no. 2 and no. 3, with the former being much more numerous. pc organisms were loca ... | 1998 | 9476643 |

| simultaneous pneumocystis carinii and pneumococcal pneumonia in human immunodeficiency virus-infected children. | three children with acquired immunodeficiency syndrome who had pneumonia develop were infected simultaneously with pneumocystis carinïi and streptococcus pneumoniae. such coexistence has not been previously reported in children. one patient received prophylactic treatment against pneumocystis carinïi before his illness. | 1998 | 9470024 |
| improved survival among hiv-infected individuals following initiation of antiretroviral therapy. | clinical trials have established the efficacy of antiretroviral therapy with double- and triple-drug regimens for individuals infected with the human immunodeficiency virus (hiv), but the effectiveness of these regimens in the population of patients not enrolled in clinical trials is unknown. | 1998 | 9466638 |
