Histoplasmosis, a fungal infection caused by Histoplasma capsulatum, is endemic in many parts of the world. However, this is not common in Japan. ⋯ The histological findings coupled with molecular confirmation led to final a diagnosis. This case emphasizes the diagnostic challenges associated with histoplasmosis in immunocompromised patients and underscores the importance of considering it in the differential diagnosis of any atypical presentation in rheumatic patients.

Eosinophilic pneumonia is a known side effect of dupilumab; however, diffuse alveolar hemorrhage has not yet been reported in association with dupilumab. We herein report a case of diffuse alveolar hemorrhage caused by dupilumab. A 57-year-old man with severe asthma was unable to discontinue oral steroids and thus was prescribed dupilumab. ⋯ Bronchoscopy revealed diffuse alveolar hemorrhage characterized by hemosiderin-phagocytic macrophages in the bronchoalveolar lavage fluid without eosinophils. The steroid dosage improved the respiratory status and resolved the infiltrate shadow. Dupilumab may thus cause diffuse alveolar hemorrhage, which can be differentiated using bronchoscopy.

X-linked agammaglobulinemia (XLA) is associated with an increased risk of gastrointestinal cancers including gastric cancer (GC). We herein report the case of a 30-year-old male patient with XLA who developed GC and extensive atrophic gastritis. ⋯ Immunoglobulin deficiency makes these patients susceptible to progressive atrophic gastritis and the associated risk of GC. Therefore, patients with XLA are advised to undergo an evaluation for Helicobacter pylori infection as well as monitoring for GC.

Objective The long-term impact of personalized diet and exercise programs for steatotic liver disease (SLD) remains unclear. Materials The subjects of this retrospective cohort study included 104 consecutive Japanese patients with SLD. The long-term treatment efficacy of personalized diet and exercise treatment was evaluated two years after the start of observation. ⋯ According to the liver function tests and physical findings, the rate of decrease in the RRH group (17 cases) was significantly higher than that in the IH group (17 cases) using a PS-matched analysis. Conclusion The present study indicated the long-term favorable efficacy of personalized diet and exercise programs for SLD. In particular, this RRH program was effective in improving the findings of liver function tests and might help to sustain diet and exercise.
