RESUMEN
BACKGROUND: Baveno VI criteria for screening varices needing treatment (VNT) have not yet been validated in an exclusive pediatric and adolescent set of the population, in whom baseline parameters differ in relation to adults. Therefore, our primary objective was to validate Baveno VI and its expanded form in children below 18 years of age. The secondary aim was to elicit whether any revision of the above criteria with a target of not missing more than 5% VNT could be more accurate for this age group. MATERIALS AND METHODS: The work was carried out in two medical institutes, over a span of 3 years. Consecutively enrolled patients below 18 years of age, with compensated cirrhosis confirmed by liver biopsy, were evaluated for related blood parameters, transient elastography (TE) and esophagogastroduodenoscopy. RESULTS: Out of the 33 recruited patients, five (15.15%) met the criteria for VNT. The sensitivity, specificity, PPV and NPV of Baveno VI and Expanded Baveno VI were observed as 60%, 92.3%, 60% and 92.3%, and 20%, 100%, 100% and 88%, respectively. We found that the Revised Baveno VI criteria with TE <19 kPa and platelet count of >175×109 cells/L, with sensitivity 100%, specificity 79%, PPV 45%, NPV 100% and accuracy of 82%, are more appropriate for this age group. CONCLUSION: We propose that further multicentrer studies with a larger sample size should be conducted before incorporating Revised Baveno VI criteria for high-risk varices in patients below 18 years in future guidelines.
RESUMEN
BACKGROUND: Prednisolone dosing regimen based on body surface area (BSA) or body weight (BW) in managing uncomplicated nephrotic syndrome (NS) has been a matter of controversy. METHODS: In this parallel-arm randomized clinical trial, 60 children with uncomplicated NS in relapse were randomized to receive either of two regimens. Children of BW cohort received prednisolone (2 mg/kg/day) till remission (or 6 weeks for first episode); followed by 1.5 mg/kg on alternate days for 4 weeks (or 6 weeks for first episode). Children randomized for BSA cohort received prednisolone (60 mg/m2/day) till remission (or 6 week for first episode); followed by 40 mg/m2 on alternate days for 4 weeks (or 6 weeks for first episode). The primary endpoint was 6-month relapse-free survival in the intention-to-treat population (clinical trial registry of India CTRI/2015/03/005655). RESULTS: The 6-month relapse-free survival rates were similar for both BSA cohort 73.33% (22/30) and BW cohort 70% (21/30) (p = 1, OR 0.19, 95% CI 0.07-0.52). Requirement of cumulative steroid to achieve initial remission (96.1 ± 57.8 vs 63.58 ± 40.2 mg/kg, p = 0.014) and over 6-month study period (104.34 ± 50.82 vs 73.88 ± 42.95 mg/kg, p = 0.015) were significantly higher in BSA cohort in comparison to BW cohort. However, time taken in achieving remission during enrolment episode in both BSA and BW groups was comparable (7 ± 1.7 vs 6.9 ± 1.4 days, p = 0.81). While both treatments were well tolerated, the number of adverse events was one and half times as common in the BSA group than BW group (37 vs. 22 events). CONCLUSIONS: In treating children with uncomplicated NS, both BSA and BW regimens were equally effective in achieving initial remission and maintaining disease remission. Due to fewer adverse events and lesser cumulative steroid exposure with BW based regimen, it may be considered as better option over BSA regimen.
