Background: Acute nephritic syndrome (ANS) is major cause of morbidity in developing countries. This study is an attempt to evaluate the clinical characteristics, complications and outcome of acute nephritic syndrome.

Methods:This hospital based descriptive study was conducted at a tertiary care hospital in Kerala, South India. 103 children with ANS were analysed. Detailed clinical examination and relevant laboratory investigations were done. These children were followed up for 1 year.

Results: Out of 103 patients studied 64% were male and 36% were female. The peak age group was 6 to 8 years. Skin infection was the most common predisposing condition (68.9%). Hypertension was present in 60.1% of patients. 26.2% of patients developed complications. Of these Acute renal failures was the most commonly encountered complication (18.4%). Proteinuria (87.4%) and microscopic hematuria (80.6%) were the most consistent features.  82.5 % patients had low C3 at the time of diagnosis. Majority of patients with low C3 level had positive ASO titre. (p = 0.014). At 3month follow up C3 became normal in 95.2% of patients. At 3 months’ majority of patients with normal C3 had incomplete recovery. (p = 0.010). At the end of 12m, microscopic heamaturia was present in 4 patients, persistent hypertension in 2 patients, 11 patients had proteinuria. These patients are kept under long term follow up.

Conclusions:Complications and morbidity is significantly high during the acute phase in ANS. This study highlights the need for long term follow up of these patients.
