Malignant peritoneal mesothelioma (MPM) is a rare malignant tumor with peritoneal thickening. Tuberculous peritonitis also shows peritoneal thickening, so differentiating between the two is important but difficult if latent tuberculosis infection (LTBI) is present. We herein report a patient with MPM and LTBI. ⋯ Interferon gamma release assay (IGRA) results were positive, suggesting tuberculous peritonitis. He underwent a laparoscopic omental biopsy and was diagnosed with MPM, which can occur together with LTBI. If peritoneal thickening is observed, an IGRA should be performed early, and the possibility of LTBI should be considered.

Observational Study
Association of the Low-density Lipoprotein Cholesterol/High-density Lipoprotein Cholesterol Ratio with Glecaprevir-pibrentasvir Treatment.
Objective The change in serum lipid levels by direct-acting antiviral (DAA) treatment for chronic hepatitis C varies depending on the type of DAA. How the lipid level changes induced by glecaprevir-pibrentasvir (G/P) treatment contribute to the clinical outcome remains unclear. We conducted a prospective observational study to evaluate the effectiveness of G/P treatment and the lipid level changes. ⋯ Specifically, the TC and LDL-C levels increased during and after treatment, and the HDL-C levels increased after treatment. G/P treatment may be associated with a reduced thrombotic risk. Therefore, validation in large trials is recommended.

Treatment with anti-programmed cell death-1 (PD-1) antibodies improves the anti-cancer immune response and can provide a meaningful clinical benefit to cancer patients. However, this treatment can result in specific autoimmune toxicities, termed immune-related adverse events (irAEs). ⋯ However, reports on nontuberculous mycobacterial infection during anti-PD-1 antibody treatment are still rare. We herein report the first case of Mycobacterium mageritense infection during anti-PD-1 antibody treatment.

Glecaprevir/pibrentasvir (GLE/PIB) is a pan-genotype anti-hepatitis C virus (HCV) therapy with high efficacy and safety. However, evidence supporting retreatment following failure of the GLE/PIB regimen is limited. ⋯ With combination therapy of sofosbuvir/velpatasvir plus ribavirin (SOF/VEL+RBV) for 24 weeks, all 3 patients had achieved a sustained viral response (SVR) at 24 weeks after completing treatment. SOF/VEL+RBV therapy was effective for retreatment of HCV after failure of GLE/PIB therapy.
