Disease: Rhinocerebral mucormycosis

Invasive nasal and paranasal mucormycosis in a patient with severe dengue fever and multiple risk factors: A case report and literature review

mycolabadmin

A 50-year-old woman in Vietnam developed a rare and deadly fungal infection called mucormycosis while recovering from dengue fever. She had weakened immunity from taking steroids for other conditions and from the dengue virus itself. The infection caused black, dead tissue to rapidly spread in her nose and around her eye. Despite treatment with antifungal medications, the infection progressed, and she died within days. The case shows how important it is to watch for dangerous opportunistic infections in dengue patients, especially those already dealing with weakened immune systems.

The expression of fungal CotH, human glucose-regulated protein 78 (GRP78), and predicted miRNAs in macrophages and diabetic mice infected with Rhizopus oryzae

Mucormycosis is a serious fungal infection caused by Rhizopus oryzae that is particularly dangerous for people with diabetes. This study shows that a fungal protein called CotH3 attaches to a human cell receptor called GRP78, allowing the fungus to invade cells more easily in diabetic patients. The research found that diabetes increases GRP78 production, making fungal invasion more likely, while antifungal treatment (liposomal amphotericin B) can reduce the expression of both CotH3 and GRP78.

Invasive Rhinocerebral Mucormycosis Is a Rare Complication in Systemic Juvenile Idiopathic Arthritis Patient

A 5-year-old girl with a serious joint disease called systemic juvenile idiopathic arthritis developed a dangerous fungal infection in her nasal cavity and brain area. The fungal infection, caused by a mold organism called Lichtheimia, occurred because her immune system was severely weakened by medications used to treat her arthritis. Doctors treated the infection with antifungal drugs and surgery, and the patient eventually recovered by switching to a different arthritis medication. This case highlights how the strong medications needed to control some childhood arthritis can unexpectedly cause serious fungal infections.
