Pneumocystosis
MONDO:0019121Human pneumocystosis is caused by an infectious agent, which (after recent nomenclature and taxonomy revisions) is now classed as the fungus Pneumocystis jiroveci. The prevalence is unknown. Pneumocystis jiroveci is an opportunistic infectious agent, developing in immunosuppressed patients. It is an air-borne infection, localized to the lungs. However, extrapulmonary involvement is seen in AIDS patients. The disease manifests progressively with coughing, respiratory problems (dyspnea) and fever, followed by acute respiratory insufficiency and death within a few weeks in untreated cases. The most reliable diagnostic method is bronchoalveolar lavage. The treatment of choice is cotrimoxazole.
Also known as: PCP, PJP, Pneumocystis, Pneumocystis Pneumonia, Pneumocystis carinii pneumonia, Pneumocystis jirovecii pneumonia, Pneumocystis pneumonia, pneumocystosis

Could a shorter steroid course be just as good for HIV-Related pneumonia?
Disease control ENROLLING_BY_INVITATIONThis study compares a shortened steroid regimen (8 days for moderate, 14 days for severe pneumonia) against the standard 21-day course in 196 HIV patients with Pneumocystis pneumonia. The goal is to see if the shorter treatment is non-inferior in preventing death and complication…

Hospital at home: new study tests home care for infections
Disease control OngoingThis study looks at whether a special team of doctors and nurses can treat adults with suspected infections at home, instead of sending them to the hospital. About 500 people will be randomly assigned to either standard hospital care or home-based care from a mobile response team…

Could a simple spit test replace the dreaded deep nose swab?
Knowledge-focused OngoingThis study compares new, less invasive ways to collect samples for respiratory virus testing—like a nasal wash or saliva—against the standard deep nose swab. Researchers want to see if these gentler methods work just as well and cause less pain. About 1,000 adults in the emergenc…
