A Retrospective Study of Acute Renal Failure in Children: Its Incidence, Etiology, Complications and Prognosis

Background: Acute renal failure (ARF) developed due to various causes and may lead to significant morbidity and mortality among pediatric patients.

Objectives: The study was conducted to determine the incidence, etiology, outcome of treatment and clinical presentation of ARF in pediatric patients in Somalia.

Methods: Comprehensive case history of 39 pediatric patients below 12 years of age, admitted with renal diseases in four tertiary care hospitals in Hargeisa and Borama cities in Somalia during December 2015 to November 2016. They were subjected to clinical investigation and laboratory test analysis based on the inclusion criteria of renal insufficiency characterized by serum creatinine level more than 1.5 mg/dl.

Results: ARF was most commonly found in five to 12 years age group (53.8%) compared to infant (zero to one year) and pre-school (one to five years) children (23.08%). Mean age of presentation was 6.14 years. Male female ratio in this study was 1.2: 1. Most common presenting clinical feature in our study was oliguria (97.43%), swelling (69.2%), fever (84.1%), abdomen pain and nausea-vomiting (41.02%). Common clinical signs were edema (66.66%), altered sensorium (51.28%), hematuria (48.71%) and hypertension (38.46%). Snake bite and acute post streptococcal glomerulonephritis were the two most common causes of ARF in children in our study. Common complications were hypertension (38.46%), anemia (35.89%), hyperkalemia (25.64%) and infection (20.51%), all of which were within the previously reported range. The factors which correlated positively with increased mortality and morbidity were females with age below one year , etiology like septicemia and systemic lupus erythematosus (SLE), high peak serum creatinine concentration and complicated by disseminated intravascular coagulation (DIC).

Conclusion: Many causes of ARF are preventable and it should be possible to reduce mortality and morbidity due to ARF through purposive preventive measure and availability of the better medical facility.
