Disease: Toxoplasmosis

Access to diagnostic testing for invasive fungal diseases and other opportunistic infections in Mexican health care centers caring for patients living with HIV

This study examined the availability of diagnostic tests for fungal and other serious infections in Mexican HIV clinics. Researchers found that most clinics, especially smaller primary care facilities, lack modern rapid testing equipment needed to quickly diagnose dangerous infections like cryptococcosis and histoplasmosis. These infections are common in people with advanced HIV and can be life-threatening, making access to rapid diagnosis crucial for treatment and survival.

Disseminated histoplasmosis with bone marrow infiltration in a newly diagnosed HIV patient

mycolabadmin

A Colombian patient living in Spain developed a serious fungal infection (histoplasmosis) that spread throughout his body and affected his bone marrow, which was discovered during his HIV diagnosis. Doctors identified the infection by examining bone marrow cells under a microscope and confirmed it with fungal culture and genetic testing. The patient was treated with antifungal medication (liposomal amphotericin B) along with HIV medications and recovered well, highlighting the importance of bone marrow testing in severely immunocompromised HIV patients.

Multicenter performance evaluation of the “quanty TOXO (RH region)” kit (Clonit) for molecular diagnosis of toxoplasmosis

mycolabadmin

Researchers from seven French hospitals tested a commercial DNA test kit called “quanty TOXO” that detects Toxoplasma gondii, a parasite causing serious infections in pregnant women and people with weakened immune systems. The kit performed well overall, correctly identifying infection in nearly 95% of positive cases and showing no false positives. However, the test sometimes missed infections when parasite levels were very low, suggesting doctors should run tests twice to increase detection chances.
