Abstract VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory somatic) syndrome has a poor prognosis, with infections being a major cause of death. Raoultella ornithinolytica is an environmental bacterium found predominantly in soil and water. Although R. ornithinolytica can cause various infections, necrotizing fasciitis due to this bacterium has not been reported. We describe the case of an 84-year-old Japanese male with VEXAS syndrome who developed septic shock and necrotizing fasciitis while he was under immunosuppressive therapy. The pathogen was initially misidentified as R. planticola by mass spectrometry but later confirmed by whole-genome sequencing as extended spectrum β-lactamase (ESBL) produced by R. ornithinolytica. Although a life-saving leg amputation was required, the patient recovered with appropriate antibiotic therapy. R. ornithinolytica is thus able to cause severe skin infections in immunocompromised individuals.

Abstract In Japan, antiviral agents for COVID-19 were freely available until September 2023 as part of national policy. This study evaluated changes in these agents’ prescribing patterns and the patient outcomes following the policy shift. We conducted a multicenter retrospective study at four hospitals in Japan’s Okayama and Kagawa prefectures from January 2022 to March 2024. The study period was divided into the public-expenditure phase (January 2022 to September 2023) and the post-expenditure phase (October 2023 to March 2024). We extracted the hospitalized patients’ clinical data from the electronic database. The study’s primary outcome was the antiviral prescription rate; the secondary outcome was in-hospital mortality. Among the 302 hospitalized patients (median age 85 years), 52.0% were classified as having a mild condition. Of the patients with mild conditions, 37.7% were diagnosed in outpatient settings prior to hospitalization. During the public-expenditure phase, 47.4% of the patients received antivirals as outpatients, mainly molnupiravir (80.9%). In the post-expenditure period, 80.0% of the patients were prescribed antivirals, mostly molnupiravir (91.7%). The antiviral prescription rate was significantly higher after the policy change. The overall in-hospital mortality was 15.8%, with no significant difference between the two periods (17.0% vs. 10.5%). Despite the termination of government funding, antiviral prescriptions remained frequent at community hospitals located in highly aging regions of western Japan such as Okayama and Kagawa prefectures. Mortality remains high among the elderly, highlighting the need for continued antiviral therapy and booster vaccinations.
