Kidney dysfunction is a frequent yet underrecognized complication of COVID-19 and a major driver of poor outcomes. Data from sub-Saharan Africa remains limited, despite the region’s vulnerability to resource constraints and delayed diagnosis. We evaluated the burden, predictors, and mortality associated with kidney dysfunction among hospitalized COVID-19 patients in northern Tanzania.
We performed a hospital-based cross-sectional study of adults with RT-PCR–confirmed COVID-19 admitted to Kilimanjaro Christian Medical Centre between March 2020 and January 2022. Demographic, clinical, and laboratory variables were extracted from medical records. Kidney dysfunction was defined as serum creatinine >108 µmol/L (men) or >97.2 µmol/L (women). Logistic regression identified predictors, and Cox proportional-hazards modeling assessed mortality risk.
Among 504 patients (mean age 62.7 ± 17.4 years; 56% male), kidney dysfunction occurred in 215 (42.6%). Independent predictors included age ≥ 60 years (AOR 2.11; 95% CI 1.09–4.07), male sex (AOR 1.56; 95% CI 1.07–2.67), and hypertension (AOR 1.51; 95% CI 1.02–2.24). Mortality among those with kidney dysfunction reached 54%, escalating to 74% during the fourth COVID-19 wave. Advanced age remained a strong predictor of death (AHR 2.32; 95% CI 1.16–4.64).
Kidney dysfunction was highly prevalent and strongly associated with mortality among hospitalized COVID-19 patients in Tanzania. Older age, male sex, and hypertension independently predicted kidney involvement and poor outcomes. Mortality more than doubled in patients with kidney dysfunction and peaked during later pandemic waves, highlighting the combined effects of patient vulnerability and health system constraints. Routine kidney function monitoring, early correction of reversible factors, and strengthened nephrology preparedness should be integral to pandemic response strategies in resource-limited settings, transforming lessons from COVID-19 into readiness for future global health crises.
