Genotype correlates with the natural history of severe bile salt export pump deficiency Highlights NAPPED is the largest global database of genotyped patients with BSEP deficiency. The genotype of patients with BSEP deficiency predicts survival with native liver. Genotype predicts long-term benefit of interruption of enterohepatic circulation. Serum bile acids can be a surrogate marker for long-term outcome. Treatment of patients with BSEP deficiency should be based on genotype.

Mutations in ATP8B1 can lead to familial intrahepatic cholestasis type 1 (FIC1) deficiency, or progressive familial intrahepatic cholestasis type 1 (PFIC1). The rarity of FIC1 deficiency has largely prevented a detailed analysis of its natural history, effects of predicted protein truncating mutations (PPTMs), and possible associations of serum bile acid (sBA) concentrations and surgical biliary diversion (SBD) with long-term outcome. We aimed to provide novel insights by using the largest genetically defined cohort of FIC1 deficiency patients to date. This multicenter, combined retrospective and prospective study included 130 patients with compound heterozygous or homozygous predicted pathogenic ATP8B1 variants. Patients were categorized according to the number of PPTMs (i.e., splice site, frameshift due to deletion or insertion, nonsense, duplication); FIC1-A (n=67; no PPTM), FIC1-B (n=29; one PPTM) or FIC1-C (n=34; two PPTMs). Survival analysis showed an overall native liver survival (NLS) of 44% at age 18y. NLS was comparable between FIC1-A, FIC1-B, and FIC1-C (%NLS at age 10y: 67%, 41%, and 59%, respectively; P=0.12), despite FIC1-C undergoing SBD less often (%SBD at age 10y: 65%, 57%, and 45%, respectively; P=0.03). sBAs at presentation were negatively associated with NLS (NLS at age 10y; sBAs <194 µmol/L: 49% versus sBAs ≥194 µmol/L: 15%; P=0.03). SBD decreased sBAs (230 [125-282] to 74 [11-177] μmol/L; P=0.005). SBD (HR 0.55, 95% CI 0.28-1.03, P=0.06) and post-SBD sBA concentrations <65μmol/L (P=0.05) tended to be associated with improved NLS.
Conclusion:Less than half of FIC1 deficiency patients reach adulthood with native liver. The number of PPTMs did not associate with the natural history or prognosis of FIC1 deficiency. sBA concentrations at initial presentation and after SBD provide limited prognostic information on long-term NLS.
Objectives:
Limited data exist about the impact of the coronavirus disease 2019 (COVID-19) pandemic on the training and clinical practice of young doctors. The aim of this study was to evaluate the impact on paediatric gastroenterologists in training posts during the first wave of the European COVID pandemic.
Methods:
All Young members of European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) (YE) members received a multiple-choice questionnaire concerning the impact (if any) on their clinical practice, mental health, quality of care provided and fellowship/training experience. The survey was conducted between May 22, 2020 and June 10, 2020.
Results:
Of the 144 responders (40% of YE members), 85% (n = 123) reported an impact of COVID-19. Ninety-six percent reported an impact on their clinical practice, including more virtual patient consultation (n = 91), underutilization of ambulatory care (n = 113) and reduced or lack of planned admissions (n = 75). Endoscopy restrictions to semi-urgent or emergency cases were reported in 82 and lack of medical equipment/drugs (n = 47) were also reported.
Reported adverse mental health issues included poor concentration, increased stress levels, an impact on family life in 62% and a reduced quality of care in 45%; this was more often reported in doctors from Southern Europe (54%) than in those from other geographical areas.
Seventy-seven percent reported an impact on the content of their fellowship, including lack of participation in national/international meetings, withdrawn research time and limited mentoring.
Conclusions:
The impact of the COVID-19 pandemic has been shown to affect the clinical practice, training and mental health of YE members. Adaptations of training programmes and targeted strategies to improve the clinical practice of young practitioners are needed and proposed in this manuscript.
In adult therapy, arsenic trioxide (ATO) and all-trans-retinoic acid (ATRA) are recognized as active treatment of relapsed acute promyelocytic leukemia (APL). The efficacy of this combination in pediatric APL has not yet been well established. We report the case of a 6-year-old girl with relapsed APL, with a PML-RARα mutation, treated with a combination of ATO and ATRA. Over a period of 5 months, she received in total, 75 doses of intravenous ATO and 40 doses of oral ATRA. Currently, 22 months after relapse, she is still in complete remission. Here, we describe treatment of a relapsed APL in a child with limited treatment of ATO and ATRA and review the literature.
