Hepatitis B virus (HBV) infection is one of the serious health problems in the world as HBV causes severe liver diseases. Moreover, HBV reactivation has occasionally been observed in patients with resolved HBV infection and patients using immunosuppression and anticancer drugs. Large-scale hospital data focused on HBV infection and severe liver function were analyzed at our hospital, located in an urban area adjacent to Tokyo, the capital city of Japan. A total of 99,932 individuals whose blood samples were taken at 7,170,240 opportunities were analyzed. The HBV surface antigen (HBsAg)-positive group had a more frequent prevalence of patients with higher transaminase elevations than the HBsAg-negative group. However, among the HBsAg-negative group, patients who were positive for anti-HBV surface antibody and/or anti-HBV core antibody, had more severe liver conditions and fatal outcomes. More careful attention should be paid to alanine transaminase (ALT) elevations higher than 1000 IU/L in patients who had current and previous HBV infection.

Background: The Tokyo Guidelines (TG; 2013) indicated that emergency cholecystectomy is an important early treatment option for acute cholecystitis; however, surgical intervention is not necessarily indicated in patients with advanced age. We evaluated percutaneous transhepatic gallbladder aspiration (PTGBA), percutaneous transhepatic gallbladder drainage (PTGBD), and the administration of antibiotics alone as treatment options for acute -cholecystitis., Methods: From January 2010 to December 2017, 159 patients with acute cholecystitis were treated at our institution. The data from these patients were retrospectively analyzed., Results: Of these 159 cases, 109 underwent PTGBA, 28 underwent PTGBD, and 22 were administered antibiotics alone. None of the 159 patients needed urgent (early) cholecystectomy, and all patients were discharged without mortality. PTGBA was unsuccessful in only 6 of 109 patients; PTGBD was performed in these 6 cases. Long-term follow-up was conducted in all cases. Of the 159 patients, 146 had gallbladder stones initially, while 13 had none at the time of presentation. Of these 146 patients with gallbladder stones, 84 underwent elective cholecystectomy, while 62 did not. Of the 84 patients who underwent elective cholecystectomy, 2 developed choledocholithiasis; of the 62 patients who did not undergo elective cholecystectomy, 5 developed choledocholithiasis and 2 developed acute cholecystitis. The incidences of choledocholithiasis and acute cholecystitis did not significantly differ between the 2 groups (p = 0.06)., Conclusions: Despite the recommendations in the TG (2013), emergency cholecystectomy was not needed in any of the present patients with acute cholecystitis. Acute cholecystitis can be successfully treated with -PTGBA or PTGBD, which are simple procedures with good short- and long-term safety. These procedures are highly recommended for patients with acute cholecystitis, especially in the elderly population., (© 2019 S. Karger AG, Basel.)
