Pneumocystis infectious disease

This study tests a drug called Sintilimab, which is normally used for cancer, to see if it can help people with HIV who have infections that won't go away with standard treatment. The drug works by 'waking up' exhausted immune cells. Fifty adults with HIV and a hard-to-treat infe…

This study compares two common antibiotic combinations—vancomycin with piperacillin/tazobactam versus vancomycin with meropenem—to see which is less harmful to the kidneys. About 852 hospitalized adults with serious infections will be randomly assigned to one of the two combos. T…

This study looks at which second-choice treatment works best for a serious lung infection called PCP when the usual antibiotic cannot be used due to allergies, side effects, or failure. About 416 adults with weakened immune systems (from HIV, transplants, cancer, or other causes)…

This study looks at how long steroids should be given to adults with severe Pneumocystis pneumonia (PCP), a serious lung infection common in people with weakened immune systems. About 416 participants who improve within 10 days will either stop steroids early or continue for 21 d…

This study tests whether adding corticosteroids (low or moderate dose) to standard care can reduce deaths from severe Pneumocystis pneumonia (PJP) in non-HIV patients in the ICU. PJP has a very high death rate of 60-80% in this group. The trial will compare two steroid doses agai…

This trial tests whether low or moderate doses of the steroid methylprednisolone can reduce deaths in patients with severe community-acquired pneumonia. It will enroll 1500 ICU patients with pneumonia caused by adenovirus or Pneumocystis jirovecii. The study uses an adaptive desi…

This study tests whether a lower dose of the antibiotic TMP-SMX works as well as the standard dose to prevent a serious lung infection called PJP in people who have just had a kidney transplant. About 1,084 adult first-time kidney transplant recipients will take either a low or s…

This study tests whether a short course of the steroid prednisolone can prevent paradoxical immune reconstitution inflammatory syndrome (IRIS) in people with AIDS who have low CD4 counts and are starting HIV treatment. About 131 participants will receive either prednisolone or no…

This observational study will look at 10,000 adults in intensive care units (ICUs) around the world during a single 24-hour period. Researchers want to find out how common infections and antibiotic-resistant bacteria are, how they are treated, and how patients recover. No new tre…

This research project aims to understand why older adults get more infections and why those infections can be more serious. By following 23,000 people aged 60 and older, scientists will collect health data and samples like blood and stool to study how the immune system changes wi…

This study will collect blood samples from 30,000 adults in the UK with various health conditions, including blood clots, infections, heart disease, diabetes, and more. The samples will be used to develop and fine-tune new diagnostic tests for the cobas® lumira device, which allo…

This study will follow 300 adults with severe infections in the ICU to see how levels of specialized pro-resolving mediators (SPMs)—natural molecules that help stop inflammation—change over time. Researchers will use blood samples already collected during routine care, so no extr…
