RESUMO
Introduction: COVID-19 pandemic is associated with secondary opportunistic fungal infections. These have an aggressive course with a high mortality rate. We present our experience of seven cases of post-COVID-19 fungal pyelonephritis. Methods: An observational study over a period of 8 months of May to December 2021 was carried out at our tertiary care hospital, including all patients with features of fungal pyelonephritis in post-COVID-19 setting. The patient demographics, details of previous COVID-19 infection, details of present admission and management were collected. The endpoints were either discharge from the hospital or death. Results: Seven patients were included. Mean age of presentation was 42 years (range: 20-63 years, standard deviation ± 14.2). Male-to-female ratio was 6:1. One patient was diabetic. Two patients were asymptomatic, one had mild infection, and four patients had severe COVID-19 infection as per National Institute of Health criteria. In the present admission, all patients had symptomatic pyelonephritis with laboratory parameters showing elevated D dimer, C reactive protein, and total leukocyte counts. In all seven patients, ultrasound of kidney ureter bladder region showed bulky kidney, color Doppler showed main renal arterial thrombosis in two patients, segmental arterial thrombosis in another patient. Computed tomography scan was suggestive of changes of pyelonephritis in all patients with multiple renal hypodense areas. All patients required nephrectomy with biopsy suggestive of changes of necrotizing fungal inflammation. Three patients expired. Conclusion: Management of post-COVID-19 fungal pyelonephritis should be aggressive and suspicious laboratory and imaging findings should be treated by early nephrectomy.
