Introduction: Health-related quality of life (HRQoL) is a measure of health outcomes. It assesses the subjective and overall impact of diseases on daily life. It also provides multidimensional data about physical wellbeing, family and peers relations. HRQoL studies on siblings are limited., Objective: To compare HRQoL among siblings of pediatric patients with chronic rheumatic diseases, kidney or liver transplant and healthy children whose siblings had no chronic conditions., Results: The siblings of children with kidney transplant (n: 65), liver transplant (n: 35), and chronic rheumatic diseases (n: 36) were compared to the healthy children group (n: 51). The total siblings group had a lower, statistically significant score in the physical well-being, social support and peers, and financial resources dimensions. The siblings of kidney transplant patients had a low score in the physical wellbeing (p < 0.02; effect size [ES]: 0.66) andfinancial resources (p < 0.01; ES: 0.66) dimensions. The siblings of liver transplant patients perceived a lower physical well-being (p = 0.04), less social support and peers (p < 0.01), and difficulties in relation to school environment (p < 0.02) and financial resources (p <0.01). The siblings of those with chronic rheumatic diseases had a lower score in the physical well-being (p < 0.05; ES: 0.44) and social support and peers (p <0.01; ES: 0.58) dimensions., Conclusion: HRQoL among healthy children whose siblings have a chronic disease was lower in the physical well-being, social support and peers, and financial resources dimensions compared to the healthy children group., Competing Interests: None, (Sociedad Argentina de Pediatría.)

After the implementation of universal hepatitis A virus vaccination in Argentina, the outcome of pediatric acute liver failure (PALF) remains unknown. We aimed to identify variables associated with the risk of liver transplantation (LT) or death and to determine the causes and short-term outcomes of PALF in Argentina. We retrospectively included 135 patients with PALF listed for LT between 2007 and 2016. Patients with autoimmune hepatitis (AIH), Wilson's disease (WD), or inborn errors of metabolism (IEM) were classified as PALF-chronic liver disease (CLD), and others were classified as "pure" PALF. A logistic regression model was developed to identify factors independently associated with death or need of LT and risk stratification. The most common etiologies were indeterminate (52%), AIH (23%), WD (6%), and IEM (6%). Overall, transplant-free survival was 35%, whereas 50% of the patients underwent LT and 15% died on the waiting list. The 3-month risk of LT or death was significantly higher among patients with pure PALF compared with PALF-CLD (76.5% versus 42.5%; relative risk, 1.8 [1.3-2.5]; P < 0.001), and 3 risk factors were independently associated with worse outcome: international normalized ratio (INR) ≥3.5 (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.3-7.2]), bilirubin ≥17 mg/dL (OR, 4.4; 95% CI, 1.9-10.3]), and pure PALF (OR, 3.8; 95% CI, 1.6-8.9). Patients were identified by the number of risk factors: Patients with 0, 1, or ≥2 risk factors presented a 3-month risk of worse outcome of 17.6%, 36.6%, and 82%, respectively. In conclusion, although lacking external validation, this simple risk-staging model might help stratify patients with different transplant-free survival rates and may contribute to establishing the optimal timing for LT., (Copyright © 2019 by the American Association for the Study of Liver Diseases.)

Background: We had previously described a left lateral segment hyper-reduction technique capable of sizing the graft according to the volume of the abdominal cavity of the recipient., Aim: The purpose of our study was to evaluate our 14-year live-donor liver transplantation experience with in situ graft hyper-reduction in children under 10 kg of weight., Patients and Methods: Between January 1997 and May 2011, we performed 881 liver transplants. Two hundred and seventy-seven (n = 277) involved pediatric recipients, of which 102 (37 %) were from live donors. Thirty-five (n = 35) patients under 10 kg of weight underwent hyper-reduced living donor liver transplants. There were 21 females (60 %) and 14 males (40 %), with a median age of 12 months (range 3-23) and a median weight of 7.7 kg (range 5.6-10)., Results: Median operative time was 350 min (range 180-510). Median cold ischemia time was 180 min (range 60-300). Twenty-six (n = 26) patients required intraoperative transfusion of blood products. There were 49 postoperative complications involving 26 patients (74 % morbidity rate). One-, 3-, and 5-year survival rates were 87, 79, and 74 %, respectively. Twenty-eight patients are currently alive., Conclusions: Hyper-reduced grafts provide an alternative approach for low-weight pediatric recipients. The relatively high immediate postoperative morbidity could be related to the complexity of these patients.

HRQOL in children after LT has not been systematically measured in transplant recipients from South American countries. The aim of this study was to determine the HRQOL using a validated measure for children. The CHQOL-PF50 was completed by the parents of 54 patients after the clinical assessment. Subscale mean scores were compared with both a normal population (n = 274) and a group of chronic illness patients with Juvenile Idiopathic Arthritis (n = 23). Compared with the normal population, LT recipients had lower subscales scores for general health perceptions, role/social emotional, mental health, and parental impact on time. Bodily pain was significantly lower in our study group. Both mean physical and psychosocial summary scores were lower compared to the normal population but similar to the JIA group. Within the LT population, gender, original diagnosis, type of immunosuppression, type of transplant and time elapsed since LT did not significantly influence any of the summary scores. Our study showed LT children's physical and psycho-social areas were lower compared with those of the general population. LT children had less limitations due to pain. Family functioning appeared normal.
