Abstract
DI PINTO, Diana and ADRAGNA, Marta. Renal manifestations in children with Alagille syndrome. Arch. argent. pediatr. [online]. 2018, vol.116, n.2, pp.149-153. ISSN 0325-0075. http://dx.doi.org/10.5546/aap.2018.149.
Introduction. Alagille syndrome (AS) is a cholestatic disease secondary to scarcity of interlobular bile ducts. It is associated with extrahepatic manifestations, and renal involvement is frequent. Objectives. To describe the prevalence, type and outcome of renal pathology in children with AS. Patients and Methods. The presence and outcome of renal pathology was retrospectively studied in 21 children who met AS criteria. Results. Renal pathology was observed in 18 patients (85.7%): (1) ultrasound variations in 7 patients (6 cases of bilateral renal dysplasia and 1 case of renal agenesis); (2) distal renal tubular acidosis in 2 patients; (3) a drop in glomerular filtration and/or proteinuria in 16 patients. The frequency of a drop in glomerular filtration was similar between patients with and without pathological kidney ultrasound findings. Conclusions. Our study confirms a high prevalence of renal involvement, which enhances the importance of diagnosis and renal function follow-up in children with AS.
