We describe a case of nephrotic syndrome (NS) after a 7 months treatment with D-penicillamine in a 14 years old girl with Wilson’s disease , with a prompt regression at the discontinuation of the drug. Kidney function, proteinuria in particular, must be always monitored during the chelating therapy, and the drug must be discontinued as soon as signs of renal injury are detected.

Background: Autoimmune liver disease (AILD) includes autoimmune hepatitis (AIH) and autoimmune sclerosing cholangitis (ASC). AILD is often associated with other extra-hepatic immune-mediated disorders (EDs), but there are few pediatric studies available to date. In this study we evaluated the association between AILD and EDs in our pediatric series., Methods: In this single centre retrospective study 48 patients (39 AIH and 9 ASC children) were evaluated. Thirty-six children were primarily referred to our Centre for liver disease suspicion, while the remaining twelve had a previous diagnosis of EDs. All the patients were screened for various EDs at AILD diagnosis and yearly during the follow-up., Results: Mean duration of follow-up was 9 years and 1 month. Twenty-two (46%) patients had a diagnosis of EDs. Ulcerative colitis (UC) was the most frequent EDs (9 patients), followed by autoimmune thyroid disease (5 patients) and celiac disease (5 patients). In 7 out of 9 UC patients, ASC was present., Conclusions: Our study showed a high association (46%) between AILD and EDs. In particular, in 8 out of 9 ASC patients UC was diagnosed (p-value 0.007). It is important to look for EDs in AILD children and, conversely, AILD in EDs children with abnormal liver function tests., (Copyright © 2018. Published by Elsevier Ltd.)

Introduction: Posterior reversible encephalopathy syndrome (PRES) with status epilepticus may occur after liver transplant. This may rarely lead to refractory epilepsy and hippocampal sclerosis (HS)., Case Description: We report the first case of epilepsy surgery in a liver-transplanted patient with refractory temporal lobe epilepsy. A 3-year-old girl underwent liver transplant for congenital biliary atresia. Four days after transplant she manifested PRES with status epilepticus, but she recovered within a couple of weeks. At the age of 5 years she started presenting complex partial seizures, that became refractory to antiepileptic drugs (AED), worsening psychosocial performances. The pre-surgical work-up identified a left HS and temporal pole alterations. A left antero-mesial temporal lobectomy was performed, leading to epilepsy remission and allowing AED withdrawal., Conclusion: Drug-resistant temporal lobe epilepsy and HS may occur as sequelae of PRES with status epilepticus related to liver transplant and cyclosporine use. In this setting early epilepsy surgery may reduce the time of chronic exposure to AED and severe illness due to repeated seizures. This option might have additional advantages in the subgroup of epileptic patients with liver transplant, preserving the liver from the potential damage due to multiple AED trials and their interaction with commonly used immunosuppressant drugs., (Copyright © 2016 European Paediatric Neurology Society.

Alpha1-antitrypsin deficiency is an autosomal recessive disease characterized by reduced serum levels of alpha1-antitrypsin (AAT) due to mutations in the SERPINA1 gene causing early onset pulmonary emphysema and, occasionally, chronic liver disease. We report an incidental finding of a novel null AAT allele, Q0Milano, consisting of a 17 nucleotides deletion in exon 3 of SERPINA1 gene, in an Italian child with persistently increased liver enzymes, a mild decrease in circulating AAT levels and without any pulmonary disease. Q0Milano variant results in an unfunctional protein lacking of AAT active site, as the resultant protein is truncated near PiS locus involved in AAT protein stability.

We describe the case of an 11-year-old obese child with nonalcoholic steatohepatitis and Wilson's disease. Nonalcoholic steatohepatitis, although frequently found in patients with obesity, can also be caused by other etiologies, including Wilson's disease, which must therefore always be ruled out in the obese child.
