Anti-glomerular basement membrane (GBM) disease with isolated diffuse alveolar hemorrhage (DAH) is rare. We herein report a 91-year-old man admitted with hypoxia and diagnosed with anti-GBM disease with DAH based on positive bronchoalveolar lavage and serum antibody test results. ⋯ Rituximab 375 mg/m2 was administered 4 times weekly; thereafter, DAH relapse was not observed, and the glucocorticoid dosage was tapered. Rituximab was thus effective in treating anti-GBM disease with isolated DAH in an extremely elderly patient.

Multicenter Study Observational Study
The Clinical Evaluation of Third-generation Cephalosporins as Definitive Therapy for Enterobacter spp. and Klebsiella aerogenes Bacteremia.
Objective Third-generation cephalosporins (3GCs) may be susceptible in vitro to Enterobacter spp. and Klebsiella aerogenes. However, treatment with mainly fourth-generation cephalosporins or carbapenems is currently recommended. Diversification of antimicrobial agents in therapy is required to avoid the selection pressure of resistant organisms by broad-spectrum antimicrobial agents. ⋯ There were no significant differences between groups in rates of switching to a susceptible antimicrobial or adding another agent, relapse within 30 days, or death within 30 days. In the 3GC group, source control was associated with favorable clinical outcomes. Conclusion Definitive 3GC therapy for susceptible Enterobacter spp. and Klebsiella aerogenes bacteremia is as clinically effective and valuable a targeted therapy as non-3GC therapy and can be implemented under conditions in which infection source control measures are in place.
