Clinical, Paraclinical Characteristics in Children with Renal Tubular Acidosis

Abstract

This descriptive study describes the clinical, paraclinical characteristics in children with renal tubular acidosis. In this study, 36 children with renal tubular acidosis were hospitalized in the National Hospital of Pediatrics from June, 2012 to July, 2017. Among the patients, 64.0% were male; the male/female ratio was 1.8/1. The average age of the patients was 7.7 ± 4.6 years. There were 29 type 1 renal tubular acidosis patients (80.6%) and 7 type 2 renal tubular acidosis (19.6%). The most common clinical signs were slow weight gain (100%), polyuria and vomiting were 25.7%, excessive water drinking (16.7%), diarrhea (13.9%), weak lower limb (11.1%), and apnea (8.3%). The laboratory values on admission were: blood pH 7.23 ± 0.11; HCO3- 12.5 ± 5.07; serum sodium 136 ± 7mmol/l; potassium 2.9 ± 0.5 mmol/l; chloride 112 ± 9 mmol/l. The study concludes that 53.8% of the clinical, paraclinical characteristics in children with Renal Tubular Acidosis were inconspicuousness, which effected the children’s growth. The study recommends a long-term strategy for diagnosis and follow–up treatment of renal tubular acidosis.
