To identify risk factors for the occurrence of Kaposi's sarcoma and Pneumocystis carinii pneumonia in homosexual men, we conducted a case-control study in New York City, San Francisco, Los Angeles, and Atlanta. Fifty patients (cases) (39 with Kaposi's sarcoma, 8 with pneumocystis pneumonia, and 3 with both) and 120 matched homosexual male controls (from sexually transmitted disease clinics and ...
Pneumocystis is a major cause of pneumonia in immunocompromised individuals, including those with AIDS and those receiving immunosuppressive therapy. During the early stage of the AIDS epidemic, there were approximately 20,000 cases of Pneumocystis pneumonia (PcP) per year. The incidence of PcP started to decline when prophylaxis was recommended in 1989 for HIV-infected patients with a CD4+ cel...
Pneumocystis jirovecii causes pneumonia in immunosuppressed individuals. However, it has been reported the detection of low levels of Pneumocystis DNA in patients without signs and symptoms of pneumonia, which likely represents colonization. Several studies performed in animals models and in humans have demonstrated that Pneumocystis induces a local and a systemic response in the host. Since P ...
A diagnostic method for pneumocystis carinii a causative agent of pneumonia in immunodeficient rats.
Immunodeficient animals are in demand in current biomedical research, and they contribute to medical progress. In Pneumocystis infections, a specific histological diagnostic tool may be immunochemistry (IC). However, it was recently reported that the antibody (3F6) was not suitable for detecting Pneumocystis in rats. We purchased another antibody [PNC007] from a commercial source for IC. We cou...
To develop and evaluate severity-adjusted indicators of treatment timeliness and adequacy for inpatient care of first episode of HIV-related pneumocystis pneumonia, a retrospective cohort study (n = 414) using medical record review was conducted in six California medical centers (1 January 1983-30 June 1987). Measures included patient baseline characteristics and complexity, process-of-care ind...
The technique of immunoblotting for detecting soluble Pneumocystis carinii antigen(s) in bronchoalveolar lavage fluid specimens from patients with AIDS and Pneumocystis pneumonia was evaluated. A soluble 67 kilodalton polypeptide that was immunoreactive with an anti-P carinii monoclonal antibody (2G2) was found in the supernatants of 26 lavage samples from patients with pneumocystosis. Intact o...
Inducible bronchus-associated lymphoid tissue (iBALT) is an ectopic lymphoid structure composed of highly organized T cell and B cell zones that forms in the lung in response to infectious or inflammatory stimuli. Here, we develop a model for fungal-mediated iBALT formation, using infection with Pneumocystis that induces development of pulmonary lymphoid follicles. Pneumocystis-dependent iBALT ...
Only a few cases of pneumocystis pneumonia (PCP) in Cushing's syndrome have been published in the literature so far. In the majority of these patients, the pneumonia occurred after reduction of the hypercortisolism with medicamentous treatment. We report two cases of PCP during conservative treatment of hypercortisolism. We describe clinical, imaging and laboratory findings in two patients and ...
Pneumocystis pneumonia (PcP) develops in immunocompromised patients. Alveolar macrophages play a key role in the recognition, phagocytosis, and degradation of Pneumocystis, but their number is decreased in PcP. Our study of various inflammatory components during PcP found that myeloid-derived suppressor cells (MDSCs) accumulate in the lungs of mice and rats with Pneumocystis pneumonia (PcP). We...
BACKGROUND Detection of Pneumocystis jiroveci colonization in lungs or oral samples due to high sensitivity of PCR methods results in undue treatment of patients without any symptoms of Pneumocystis pneumonia. The aim of the present study is to demonstrate Pneumocystis carinii in rats, immune suppressed by oral and subcutaneous administration of dexamethasone. MATERIAL/METHODS Blood, oral, na...
