Objective This study explored the prognostic factors of in-hospital mortality in patients with Pneumocystis pneumonia (PCP) without human immunodeficiency virus (HIV) infection, using a Japanese nationwide inpatient database. Methods We extracted the data of patients with PCP without HIV infection between July 2010 and March 2022 from the Diagnosis Procedure Combination database. We performed multivariable logistic regression analyses to identify the prognostic factors of in-hospital mortality in with PCP without HIV infection. ⋯ Higher in-hospital mortality was associated with advanced age, male sex (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.06-2.00), a low Barthel index score, non-hematological malignancy (OR, 1.81; 95% CI, 1.22-2.70), receipt of mechanical ventilation (OR, 2.49; 95% CI, 1.47-4.21), and administration of antibiotics (OR, 1.52; 95% CI, 1.12-2.06) and antifungal drugs (OR, 1.83; 95% CI, 1.26-2.67). Lower in-hospital mortality was associated with connective tissue disease and vasculitis (OR, 0.55; 95% CI, 0.37-0.81), hematological malignancy (OR, 0.59; 95% CI, 0.38-0.93), and early trimethoprim-sulfamethoxazole treatment (OR, 0.63; 95% CI, 0.44-0.90). Conclusions These findings will help physicians identify patients who may benefit from early aggressive therapeutic interventions.

A 68-year-old woman was diagnosed with leiomyosarcoma (LMS) based on preoperative biopsy of the gastric body. As tumor invasion confined to the submucosa with no breaking of the submucosal layer was confirmed on endoscopic ultrasonography (EUS), the patient underwent endoscopic submucosal dissection (ESD) for gastric LMS, resulting in complete tumor resection. ⋯ This is an extremely rare case of gastric LMS that underwent ESD after a precise preoperative diagnosis, with no signs of recurrence after treatment. ESD may be an acceptable option for gastric LMS when EUS findings allow this treatment method.

A 76-year-old woman with persistent diarrhea was referred to our hospital. She had purpura, peripheral eosinophilia (18,177/μL), and an elevated serum IgG4 level (819 mg/dL). Abdominal computed tomography revealed massive ascites and bowel edema. ⋯ Biopsies of the gastrointestinal mucosa revealed dense eosinophilic infiltration, indicating eosinophilic gastroenteritis (EG) associated with the hypereosinophilic syndrome. The number of IgG4-positive cells increased in the duodenal mucosa; however, the diagnostic criteria for IgG4-related disease (IgG4-RD) were not met. Whether or not EG with ascites is a manifestation of IgG4-RD warrants further investigation.
