| the structural mechanism for half-the-sites reactivity in an enzyme, thymidylate synthase, involves a relay of changes between subunits. | thymidylate synthase (ts), a half-the-sites reactive enzyme, catalyzes the final step in the de novo biosynthesis of deoxythymidine monophosphate, dtmp, required for dna replication. the cocrystal structure of ts from pneumocystis carinii (pcts), a new drug target for an important pathogen, with its substrate, deoxyuridine monophosphate (dump), and a cofactor mimic, cb3717, was determined. the structure, solved at 2.6 a resolution, shows an asymmetric dimer with two molecules of the substrate du ... | 1999 | 10529228 |
| development of a pcr assay for diagnosis of pneumocystis carinii pneumonia based on amplification of the multicopy major surface glycoprotein gene family. | we have evaluated a pcr technique using primers based on pneumocystis carinii major surface glycoprotein (msg) genes, a multicopy gene family, for utility in detection of p. carinii in bal and oropharyngeal samples obtained from immunosuppressed patients. these primers were able to detect p. carinii dna in as little as 16 fg of genomic dna. pcr using msg primers detected p. carinii dna in 7 smear-positive bal samples (100% sensitivity), and found no p. carinii dna in 12 smear-negative bal sample ... | 1999 | 10529878 |
| impact of bacterial pneumonia and pneumocystis carinii pneumonia on human immunodeficiency virus disease progression. pulmonary complications of hiv study group. | the course of pneumonia caused by pyogenic bacteria and pneumocystis carinii was examined in a multicity cohort study of hiv infection. the median duration of survival among 150 individuals following initial bacterial pneumonia was 24 months, compared with 37 months among 299 human immunodeficiency virus (hiv)-infected control subjects matched by study site and cd4 lymphocyte count (p<.001). for 152 subjects with p. carinii pneumonia, median survival was 23 months, compared with 30 months for 28 ... | 1999 | 10530443 |

| corticosteroids as adjunctive therapy for severe pneumocystis carinii pneumonia in non-human immunodeficiency virus-infected patients: retrospective study of 31 patients. | the aim of this retrospective study was to assess whether corticosteroid adjunctive therapy (cat) could prevent death in immunocompromised patients with severe pneumocystis carinii pneumonia (pcp) who do not have human immunodeficiency virus (hiv) infection, similarly to what has been demonstrated for hiv-infected patients. the charts of all non-hiv-infected patients who were admitted to two medical intensive care units between 1988 and 1996 because of severe pcp, defined by an arterial oxygen p ... | 1999 | 10530464 |
| analysis of pneumocystis carinii introns. | pneumocystis carinii is an ascomycete phylogenetically related to schizosaccharomyces pombe. little is known about gene regulation in p. carinii. the removal of introns from pre-mrna requires spliceosomal recognition of the intron-exon boundary. in s. pombe and higher eukaryotes, this boundary and a branch site within the intron are conserved. we recently demonstrated that p. carinii cdc2 cdna can complement s. pombe containing conditional mutations of cdc2, an essential gene involved in cell cy ... | 1999 | 10531280 |

| effects of mutations in pneumocystis carinii dihydropteroate synthase gene on outcome of aids-associated p. carinii pneumonia. | sulpha drugs are widely used for the treatment and long-term prophylaxis of pneumocystis carinii pneumonia (pcp) in hiv-1-infected individuals. sulpha resistance in many microorganisms is caused by point mutations in dihydropteroate synthase (dhps), an enzyme that is essential for folate biosynthesis. we assessed whether mutations in the dhps gene of p. carinii were associated with exposure to sulpha drugs and influenced outcome from pcp. | 1999 | 10533864 |

| pattern of opportunistic pulmonary infections in hiv sero-positive subjects: observations from pondicherry, india. | prospective analysis for a period of six-and-a-half years was done in 190 patients with hiv infection, which showed post-primary tuberculosis with sputum positive for acid-fast bacilli in 65% of cases. extrapulmonary forms of tuberculosis especially lymph nodes infection was more frequent. cervical group of lymph node involvement was the commonest presentation. procedures such as fnac/biopsy of lymph nodes and pleura provided the immediate diagnostic yields. these procedures must be considered e ... | 1999 | 10534938 |
| [pyrimethamine and sulfadoxine as a preventive treatment for pneumocystis carinii and toxoplasma encephalitis]. | few studies have been reported on the potential usefulness of fansidar combination at a fixed doses of pyrimethamine and sulfadoxine as prophylaxis for pneumonia by pneumocystis carinii and toxoplasmic encephalitis. | 1999 | 10535188 |
| pneumocystis carinii pneumonia: a clinical review. | pneumocystis carinii pneumonia (pcp) is an opportunistic infection that occurs in immunosuppressed populations, primarily patients with advanced human immunodeficiency virus infection. the classic presentation of nonproductive cough, shortness of breath, fever, bilateral interstitial infiltrates and hypoxemia does not always appear. diagnostic methods of choice include sputum induction and bronchoalveolar lavage. the drug of choice for treatment and prophylaxis is trimethoprim-sulfamethoxazole, ... | 1999 | 10537385 |
| infectious complications in chronic lymphocytic leukaemia. | infections are the major cause of morbidity and mortality in patients with chronic lymphocytic leukemia (cll). predisposition to infection in cll is mediated through various abnormalities including both the immune defects inherent in the primary disease (impairment in humoral and cellular immunity) and in the further immunosuppression related to the management of cll. hypogammaglobulinemia is probably the most important immune defect in terms of risk of severe bacterial infections, its frequency ... | 1999 | 10543369 |
