Therapeutic plasma exchange (TPE) is a strategy for treating cold agglutinin disease (CAD) in order to manage hemolytic complications. However, there are no reports of hemolysis during TPE. ⋯ To avoid low temperatures, the patient and extracorporeal circulation were kept warm by covering and heating them, and finally, he was able to successfully receive TPE three times. Although our approach still has room for improvement, our management protocol appears to be an effective treatment modality for such cases.

Objective In recent years, there has been a growing focus on health risks associated with alcohol consumption. The present study investigated whether or not the genetic variant of aldehyde dehydrogenase 2 (ALDH2) influences the risk of gastric cancer among individuals identified as hazardous drinkers using the Alcohol Use Disorders Identification Test (AUDIT), which provides a comprehensive assessment of hazardous drinking behavior. Patients We enrolled men with hazardous drinking behavior (AUDIT score ≥ 8) who had undergone gastric cancer screening (either endoscopy or a barium X-ray examination of the upper gastrointestinal tract) between April 2013 and March 2020 within 1 year from entry and who had subsequently undergone at least one more gastric cancer screening up to March 2021. ⋯ The cumulative incidence of gastric cancer in the less-active group was higher than in the active ALDH2 group (p=0.01, hazard ratio: 4.6, 95% confidence interval: 1.2-16.7). Alcohol consumption was lower in the less-active ALDH2 group than in the active ALDH2 group, although no marked difference was observed in the AUDIT score. Conclusion In individuals with hazardous drinking behavior, a heightened risk of gastric cancer was observed among those with less-active ALDH2 variants, even when their alcohol consumption was comparatively lower than in those with active ALDH2 variants.

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.
