Liver Articles: Short Takes

DBE van Wessel et al. JPGN 2017; 65: 370-74.  This retrospective study showed an increase in biliary atresia incidence in preterm infants compared with full-term: 1.06 per 10,000 compared with 0.52/10,000. In addition, 4-year transplant-free survival rates were significantly worse at 21%, whereas 4-year survival rates was 61%. Clearance of jaundice (with Kasai) was achieved in only 23%.

ES Björnsson et al. Clin Gastroenterol Hepatol 2017; 15: 1635-36. This study examined response to steroids in 18 patients with drug-induced autoimmune hepatitisKey findings: 14 patients had elevated antinuclear antibodies & there were none with elevated smooth muscle antibodies. Infliximab was most frequent agent (n=11) and nitrofurantoin was other frequent agent (n=3).  Overall, 40% improved after discontinuation of medication, the remainder had prompt responses to corticosteroids.  Relapse did not occur when corticosteroids were discontinued.  Among the infliximab group, there was no evidence of liver injury after transitioning to alternative tumor necrosis factor-α inhibitor.

M Balwani et al. Hepatology 2017; 66: 1314-22. Acute Hepatic Porphyrias -Review. Current recommendations include gene sequencing to confirm all biochemical cases. Biochemical tests are spot urine testing of porphobilinogen (PBG), 5-aminolevulinic acid (ALA), and porphyrins. A normal urine PBG in symptomatic patients “excludes the three most common acute hepatic porphyrias.”  For those with abnormal studies, this reference is a handy.

S Wirth et al. Hepatology 2017; 66: 1102-10.  This study examined the effectiveness of sofosbuvir and weigh-based ribavirin dosing in 12-17 year olds with genotype 2 & 3 Hepatitis C infection.  Duration of treatment was 12 weeks for genotype 2 and 24 weeks for type 3.  Overall, SVR12 was achieved in 51 of 52 (98%); one patient with genotype 3 did not achieve SVR12.

F Kanwal et al. Gastroenterol 2017; 153: 996-1005. This study, a retrospective cohort of 22,500 VA patients treated for hepatitis C infection, showed that direct-acting antivirals (DAAs) lowered, but did not eliminate, the risk of hepatocellular carcinoma (HCC). Among the 87% who achieved an SVR, the adjusted hazard ratio for HCC was 0.28.  This was true as well as among patients with cirrhosis.. Hazard ratio for those with compensated cirrhosis was 0.32 compared with 0.18 among those without cirrhosis.
