Etiology and outcome of chronic renal failure in hospitalized children in Ho Chi Minh City, Vietnam

The aim of this study was to investigate the etiology and treatment modalities and to determine mortality risks in hospitalized children with chronic renal failure (CRF) in Ho Chi Minh City, Vietnam. We reviewed the records of 310 children with CRF hospitalized in Ho Chi Minh City from January 2001 to December 2005. The average annual number cases was 4.8 per million child population native to Ho Chi Minh City. Median age was 14 years; 85% of patients were in end-stage renal failure. Associated illnesses were anemia (96%), hypertension (74%), and cardiopulmonary diseases (39%). Causes of included glomerulonephritis (30%) and congenital/hereditary anomalies (20%), but in 50% of children, the etiology was unavailable. Seventy-three percent of cases with end-stage renal failure did not benefit from renal replacement therapy. During hospitalization, 47 patients (15%) died. Mortality risks were higher in young children (1-4 years), in boys, and in patients with acquired pathologies. Severe metabolic acidosis was the main predictive factor of mortality by multivariate regression analysis. Our data shows a poor outcome due to late referral and limited facilities for renal replacement therapy in children with CRF hospitalized in Ho Chi Minh City.
