Context: The pattern of acute kidney injury (AKI) differs significantly between developed and developing countries. Aims: The aim of th study was to determine the pattern and clinical outcomes of AKI in Lagos, Southwest Nigeria. Settings and Design: A retrospective review of hospital records of all patients with a diagnosis of AKI over a 20-month period. Subjects and Methods: Records of 54 patients were reviewed. Information retrieved included, bio-data, etiology of AKI, results of laboratory investigations, and patient outcomes. Statistical Analysis Used: Continuous data are presented as means while categorical data are presented as proportions. The Student's t-test was used to compare means while Chi-square test was used to compare percentages. Logistic regression analysis was used to determine the factors that predicted in-hospital mortality. Results: Twenty-seven (50%) of the patients were male. The mean age of the study population was 39.7 years ± 16.3 years. Sepsis was the etiology of AKI in 52.1% of cases. Overall, in-hospital mortality was 29.6%. Patients who died had a shorter mean duration of hospital stay (9.2 days vs. 33.9 days [P < 0.01]), lower mean serum bicarbonate (19.5 mmol/L vs. 22.9 mmmol/L [P = 0.02]), were more likely to be admitted unconscious (82.4% vs. 17.6% [P = 0.01]) and to have been admitted to the Intensive Care Unit (37.5% vs. 7.9% [P = 0.01]). In addition, when dialysis was indicated, patients who did not have dialysis were more likely to die (58.3% vs. 41.7% [P = 0.02]). Conclusions: The pattern of AKI in this study is similar to that from other developing countries. In-hospital mortality remains high although most of the causes are preventable.
