RESUMO
INTRODUCTION AND AIM: Multiple prognostic scores are available for acute liver failure (ALF). Our objective was to compare the dynamicity of model for end stage liver disease (MELD), MELD-sodium, acute liver failure early dynamic model (ALFED), chronic liver failure (CLIF)-consortium ACLF score and King's College Hospital Criteria (KCH) for predicting outcome in ALF. MATERIALS AND METHODS: All consecutive patients with ALF at a tertiary care centre in India were included. MELD, MELD-Na, ALFED, CLIF-C ACLF scores and KCH criteria were calculated at admission and day 3 of admission. Area under receiver operator characteristic curves (AUROC) were compared with DeLong method. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), likelihood ratio (LR) and diagnostic accuracy (DA) were reported. RESULTS: Of the 115 patients included in the study, 73 (63.5%) died. The discrimination of mortality with baseline values of prognostic scores (MELD, MELD-Na, ALFED, CLIF-C ACLF and KCH) was modest (AUROC: 0.65-0.77). The AUROC increased on day 3 for all scores, except KCH criteria. On day 3 of admission, ALFED score had the highest AUROC 0.95, followed by CLIF-C ACLF 0.88, MELD 0.81, MELD-Na 0.77 and KCH 0.52. The AUROC for ALFED was significantly higher than MELD, MELD-Na and KCH (P < 0.001 for all) and CLIF-C ACLF (P = 0.05). ALFED score ≥ 4 on day 3 had the best sensitivity (87.1%), specificity (89.5%), PPV (93.8%), NPV (79.1%), LR positive (8.3) and DA (87.9%) for predicting mortality. CONCLUSIONS: Dynamic assessment of prognostic scores better predicts outcome. ALFED model performs better than MELD, MELD, MELD-Na, CLIF-C ACLF scores and KCH criteria for predicting outcome in viral hepatitis- related ALF.

INTRODUCTION: Hypersplenism in cirrhosis is not infrequent and may compromise with quality of life and therapy. Splenectomy is a therapeutic option, but information on results of splenectomy is scarce. MATERIAL AND METHODS: Consecutive patients with cirrhosis who underwent splenectomy between 2001-2010 were included in the study. Safety, efficacy of splenectomy and subsequent influence on therapy were evaluated. RESULTS: Thirty three patients (mean age 30.9 ± 11.6 years, 19 men, viral 48.5%, autoimmune 15.1%, cryptogenic 36.4%) underwent splenectomy. Twenty were Child's A, 13 Child's B. Twenty patients had > 6 months follow up. Common indications were inability to treat with interferon, transfusion-dependent anemia, recurrent mucosal bleeds, and large spleen compromising quality of life. Median hospital stay was 7 (4-24) days. There was no splenectomy related mortality. Twenty three (70%) patients had post-operative complications, most commonly infections. Two patients required percutaneous drainage of post-operative collections, and 1 needed re-exploration for intra-abdominal bleed. Subsequent to splenectomy platelet count (44,000 to 151,000/mm 3 , p < 0.01) and TLC (2,500 to 13,400/mm 3 , p < 0.01) had sustained increase in all patients except one. Five HCV cirrhotics completed interferon and ribavirin therapy, 4 achieved sustained viral response. The quality of life improved and there was no recurrence of infections, mucosal bleed or anemia requiring transfusions in any patient. In patients on long term follow up (median duration 27 months), the median Child's score improved from 6 at baseline to 5 at follow up (p < 0.05). CONCLUSIONS: Splenectomy was safe and effective in patients with cirrhosis, and improved therapeutic options as well as Child's score.
