    Abstract:
    BACKGROUND: Acute kidney injury (AKI) is a common contributor to morbidity and mortality in newborns, with prevalences varying by population and hospital. A study of AKI in newborns in tertiary care centers in Thailand, a developing country with limited resources, has not been conducted yet. METHODS: The aim of this study was to determine the prevalence of AKI in newborns in a tertiary care hospital in southern Thailand and to investigate the etiology, mortality and risk factors of mortality. The records of patients aged <30 days with high serum creatinine, admitted from 1984 to 2007, were retrospectively reviewed. RESULTS: Eighty-eight boys and 51 girls were enrolled; 61.4% were premature and 56.5% had a birth weight <2500 g. The prevalence of newborn AKI increased from 0.9 to 6.3% during the 24-year study period. Thirty-nine and 65% had renal failure within 2 and 7 days post-birth, respectively. Sepsis was the most common cause of AKI (30.9%) followed by hypovolemia (18.7%), kidney, ureter and bladder (KUB) anomalies (12.2%), congestive heart failure (12.2%) and birth asphyxia (11.5%). Indomethacin caused AKI in 24.4% with gestational age <32 weeks. Sepsis-induced AKI had the highest mortality rate (65.1%) with an overall mortality rate of 38.8% and nearly 14 times the risk of death compared to hypovolemia-induced AKI. CONCLUSIONS: The prevalence of newborn AKI in our Thai tertiary center over 24 years was 6.3% of admitted newborns. Sepsis was the most common cause of AKI and sepsis-induced AKI is the most common cause of death. Disease etiology was the only risk factor for mortality.
