Anti-Therapeutic Action: Breakthrough infections despite prophylaxis

Breakthrough Invasive Mould Infections Under Posaconazole Prophylaxis in Patients With Haematologic Malignancies: A Case–Control Study

This study examined cases where patients receiving posaconazole to prevent fungal infections still developed serious mould infections despite the medication. Researchers compared 29 patients who developed these breakthrough infections with 46 control patients who did not. They found that over half of patients with breakthrough infections died, compared to only 20% of controls, and that surgical treatment significantly improved survival for certain types of fungal infections.

Consecutive non-Aspergillus Fungal Invasive Infections in Chronic Granulomatous Disease: Data from the French National Reference Center for Primary ImmunoDeficiencies and literature review

This study examines rare but serious fungal infections in patients with chronic granulomatous disease, a genetic immune disorder. Researchers analyzed 122 cases of non-Aspergillus fungal infections from French hospitals and published literature, finding that these infections often occur despite preventive antifungal medications and are challenging to diagnose. The infections were found in the lungs most commonly but could spread to bones, brain, and other organs, with treatments including antifungal drugs, surgery, and in some cases bone marrow transplants.
