- Abstract
Background & Aims: Systemic corticosteroids may cause HBV reactivation, but the impact on patients with previous HBV exposure is poorly defined. We aimed to study the risk of HBsAg seroreversion and hepatitis flare in patients with previous HBV exposure., Methods: Patients who were negative for HBsAg and received corticosteroids between 2001-2010 were included. Patients who were positive for antibody to HBsAg (anti-HBs) and/or to HBcAg (anti-HBc) were defined as having previous HBV exposure. The primary endpoint was HBsAg seroreversion; the secondary endpoint was hepatitis flare (alanine aminotransferase >80 U/L) at 1 year., Results: A total of 12,997 patients fulfilled the inclusion criteria: anti-HBs positive only (n = 10,561); anti-HBc positive only (n = 970); anti-HBs & anti-HBc positive (n = 830) and anti-HBs & anti-HBc negative (n = 636). HBsAg seroreversion occurred in 165 patients. Patients who were anti-HBc positive only had a higher risk of HBsAg seroreversion (1-year incidence 1.8%) than those negative for both anti-HBs & anti-HBc (0%; p = 0.014). Patients with previous HBV exposure had a similarly low risk of liver failure as unexposed individuals (1.1% vs. 0.9%). The risk of a hepatitis flare started to increase in those receiving corticosteroids at peak daily doses of 20-40 mg (adjusted hazard ratio [HR] 2.19, p = 0.048) or >40 mg (aHR 2.11, p = 0.015) prednisolone equivalents for <7 days, and was increased at treatment durations of 7-28 days and >28 days (aHR 2.02-3.85; p <0.001-0.012)., Conclusions: In HBsAg-negative patients who were only anti-HBc positive, high peak daily doses of corticosteroids increased the risk of hepatitis flare, but not seroreversion. The rate of liver failure was low and similar in HBV exposed and unexposed individuals; there were no deaths, nor any requirement for liver transplantation., Lay Summary: It is important to know the hepatitis B virus (HBV) status before starting corticosteroid therapy. Patients with resolved HBV infection without detectable immunity are at an increased risk of HBV surface antigen seroreversion after corticosteroid therapy. High peak daily doses of corticosteroids (>40 mg prednisolone equivalents) increase the risk of hepatitis flare, but not seroreversion, in patients with previous exposure to HBV, irrespective of the duration of treatment. Interval monitoring of liver biochemistries is essential for the early detection of hepatitis flares in these patients., (Copyright © 2019 European Association for the Study of the Liver.

- Abstract
Background: Although malignant pleural mesothelioma (MPM) is generally a disease associated with more advanced age, the association of age, treatment, and outcomes has not been well-characterized. We evaluated the impact of age on outcomes in patients with MPM to provide data for use in the treatment selection process for elderly patients with potentially resectable disease., Patients and Methods: Overall survival (OS) of patients younger than 70 and 70 years or older with Stage I to III MPM who underwent cancer-directed surgery or nonoperative management in the Surveillance, Epidemiology, and End Results database (2004-2010) was evaluated using multivariable Cox proportional hazard models and propensity score-matched analysis., Results: Cancer-directed surgery was used in 284 of 879 (32%) patients who met inclusion criteria, and was associated with improved OS in multivariable analysis (hazard ratio, 0.71; P = .001). Cancer-directed surgery was used much less commonly in patients 70 years and older compared with patients younger than 70 years (22% [109/497] vs. 46% [175/382]; P < .001), but patients 70 years and older had improved 1-year (59.4% vs. 37.9%) and 3-year (15.4% vs. 8.0%) OS compared with nonoperative management. The benefit of surgery in patients 70 years and older was observed even after propensity score-matched analysis was used to control for selection bias., Conclusion: Surgical treatment is associated with improved survival compared with nonoperative management for both patients younger than 70 years and patients aged 70 years or older., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2016 Elsevier Inc.
