An entirely different spectrum of disease is seen in infants with chikungunya as compared to older children who need to be carefully observed for. The morbidity and mortality of the disease may be avoided by the rational use of drugs and close monitoring of all infants.

Auxiliary partial orthotopic liver transplantation (APOLT) in metabolic liver disease (MLD) has the advantage of correcting the metabolic defect, preserving the native liver for gene therapy in the future with the possibility of withdrawal of immunosuppression. Methods: Retrospective analysis of safety and efficacy of APOLT in correcting the underlying defect and its impact on neurological status of children with MLD. Results: A total of 13 APOLT procedures were performed for MLD during the study period. The underlying aetiologies being propionic acidemia (PA)-5, citrullinemia type 1 (CIT1)-3 and Crigler-Najjar syndrome type 1 (CN1)-5 cases respectively. Children with PA and CIT1 had a median of 8 and 4 episodes of decompensation per year, respectively, before APOLT and had a mean social developmental quotient (DQ) of 49 (<3 standard deviations) as assessed by Vineland Social Maturity Scale prior to liver transplantation. No metabolic decompensation occurred in patients with PA and CIT1 intraoperatively or in the immediate post-transplant period on protein-unrestricted diet. Patients with CN1 were receiving an average 8-15 h of phototherapy per day before APOLT and had normal bilirubin levels without phototherapy on follow-up. We have 100% graft and patient survival at a median follow-up of 32 months. Progressive improvement in neurodevelopment was seen in children within 6 months of therapy with a median social DQ of 90. Conclusions: APOLT is a safe procedure, which provides good metabolic control and improves the neurodevelopment in children with selected MLD.

To analyze the clinical characteristics and the outcomes of living donor liver transplantation in children with Alagille syndrome (AGS). Clinical data of children with AGS who underwent liver transplantation between July 2009 and May 2019 in our unit were retrospectively analyzed. Primary end‐points were patient and graft survival. Ten children with AGS underwent living donor liver transplantation at a median age of 28 months (range, 12‐84 months). Jaundice was the most common initial symptom and was noted after a median duration of 20 days after birth (range, 7‐60 days). Two patients had undergone Kasai porto‐enterostomy for misdiagnosis of biliary atresia. The most common indication for transplantation was severe pruritus with poor quality of life. Explant livers in three children showed cirrhosis with early well‐differentiated hepatocellular carcinoma. We have 100% patient and graft survival at a mean follow‐up of 32 months (range 3‐72 months). The median z‐score for weight and height at liver transplantation was −2.66 (range: −6.44 to −0.9) and −3.6 (range: −7.96 to −0.93) while at follow‐up was −1.7 (range: −3.4 to −0.35) and −2.1 (range: −3.9 to −1.4), respectively. The estimated glomerular filtration rate was normal pretransplant and follow‐up. This is the first series of LDLT for Alagille syndrome in the Indian sub‐continent. We report excellent post‐transplant outcomes in contrast to outcomes reported from Western literature.

Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the CF transmembrane conductance regulator gene. CF liver disease develops in 5%-10% of patients with CF and is the third leading cause of death among patients with CF after pulmonary disease or lung transplant complications. We review the pathogenesis, clinical presentations, complications, diagnostic evaluation, effect of medical therapies especially CF transmembrane conductance regulator modulators and liver transplantation in CF associated liver disease.

Permanent neonatal diabetes mellitus (PNDM) is characterized by the onset of diabetes within the first six months of life and insulin dependence life long. It has been recently discovered that mutation in KCNJ11 gene encoding Kir6.2, the pore forming subunit of ATP sensitive potassium channel (K ATP) is the most common cause and such patients may respond better to oral sulphonylurea drugs than insulin. Here is a rare case of permanent neonatal diabetes due to R20IC mutation in KCNJ11 gene.
