Granulicatella species are rare, nutritionally variant streptococci that cause infective endocarditis. Their clinical and microbiological characteristics remain unknown. We reviewed five years of Granulicatella cases in our hospital database (Jan 2017-Jun 2022), finding 6 Granulicatella adiacens cases and 1 Granulicatella elegans case. Clinical backgrounds and bacteremia sources were diverse; 3 cases developed polymicrobial bacteremia. Antimicrobial testing showed non-susceptibility to penicillin G in 4 of 7 cases (57.1%), and high susceptibility to carbapenems and vancomycin in all cases. Determining optimal antibiotic therapy for Granulicatella infections is vital in this era of antimicrobial resistance.

記述言語：日本語出版者・発行元：日本皮膚科学会-西部支部

71歳,女性。1年前に右膝と両側前腕に皮下硬結を自覚し,その後左臀部にも皮下硬結が出現した。右膝に20×10cm,左臀部に10×7cm,右前腕に10×7cm,左前腕に2個の7×5cmの板状皮下硬結がみられた。皮膚生検では皮下脂肪組織に非乾酪壊死性類上皮細胞肉芽腫を認め,sIL-2Rは1697.0U/mlと高値であった。胸部CTでは縦隔リンパ節の軽度腫大があり,Gaシンチグラフィーでは四肢と左臀部の皮下硬結部に高度な集積を認め,extensive subcutaneous sarcoidosisと診断した。膝関節屈曲制限が生じる懸念があったためプレドニゾロン25mg/day内服を開始したところ,皮下病変は速やかに縮小し,sIL-2Rは418.3U/mlまで低下した。皮下型サルコイドーシスではトラニラストやミノサイクリン内服で軽快する症例や,無治療で軽快する症例もあるが,本症例では,右膝部皮下病変の拡大による歩行障害が懸念されたため,ステロイド内服による治療を選択した。広範な皮下型病変を呈するサルコイドーシスでは,sIL-2Rや皮膚病変のサイズなどを総合的に評価し,病勢を検討することが必要である。(著者抄録)

OBJECTIVES: The aim of this study was to determine the characteristics of hypozincemia in long COVID patients. METHODS: This study was a single-center retrospective observational study for outpatients who visited the long COVID clinic established in a university hospital during the period from 15 February 2021 to 28 February 2022. Characteristics of patients with a serum zinc concentration lower than 70 μg/dL (10.7 μmol/L) were compared with characteristics of patients with normozincemia. RESULTS: In a total of 194 patients with long COVID after excluding 32 patients, hypozincemia was detected in 43 patients (22.2%) including 16 male patients (37.2%) and 27 female patients (62.8%). Among various parameters including the background characteristics of the patients and medical histories, the patients with hypozincemia were significantly older than the patients with normozincemia (median age: 50 vs. 39 years). A significant negative correlation was found between serum zinc concentrations and age in male patients (R = -0.39; p < 0.01) but not in female patients. In addition, there was no significant correlation between serum zinc levels and inflammatory markers. General fatigue was the most frequent symptom in both male patients with hypozincemia (9 out of 16: 56.3%) and female patients with hypozincemia (8 out of 27: 29.6%). Patients with severe hypozincemia (serum zinc level lower than 60 μg/dL) had major complaints of dysosmia and dysgeusia, which were more frequent complaints than general fatigue. CONCLUSIONS: The most frequent symptom in long COVID patients with hypozincemia was general fatigue. Serum zinc levels should be measured in long COVID patients with general fatigue, particularly in male patients.

ハンセン病に対する免疫抑制療法を背景に発症した播種性糞線虫症の1例

症例は30歳代ネパール人男性で、下痢と嘔気を主訴とした。ハンセン病(LL型)と新型コロナウイルス感染症の既往があり、らい反応に対して長期間のステロイド製剤内服による免疫抑制療法を行っていた。各種検査所見より、糞線虫の過剰感染状態による播種性糞線虫症と診断した。栄養状態は不良で、寄生虫の消化管内過剰増殖に伴う腸管浮腫を認め、イベルメクチンは吸収不良で血中濃度が不十分であった。多臓器不全を併発したため集学的治療を行ったが第36病日に死亡した。日本では糞線虫症は稀であるが、インバウンドの増加に伴い播種性糞線虫症のリスクが増加する可能性があり、ステロイドの長期内服などで免疫抑制状態の可能性がある場合は寄生虫スクリーニングを行う必要があると考えられた。

Buruli ulcer is the third most common mycobacterial infection worldwide and is mainly diagnosed in tropical regions. Globally, this progressive disease is caused by Mycobacterium ulcerans; however, Mycobacterium ulcerans subsp. shinshuense, an Asian variant, has been exclusively identified in Japan. Because of insufficient clinical cases, the clinical features of M. ulcerans subsp. shinshuense-associated Buruli ulcer remain unclear. A 70-year-old Japanese woman presented with erythema on her left backhand. The skin lesion deteriorated without an apparent etiology of inflammation, and she was referred to our hospital 3 months after disease onset. A biopsy specimen was incubated in 2% Ogawa medium at 30 °C. After 66 days, we detected small yellow-pigmented colonies, suggesting scotochromogens. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI Biotyper; Bruker Daltonics, Billerica, MA, USA) indicated that the organism was Mycobacterium pseudoshottsii or Mycobacterium marinum. However, additional PCR testing for the insertion sequence 2404 (IS2404) was positive, suggesting that the pathogen was either M. ulcerans or M. ulcerans subsp. shinshuense. Further examination by 16S rRNA sequencing analysis, focusing on nucleotide positions 492, 1247, 1288, and 1449-1451, we finally identified the organism as M. ulcerans subsp. shinshuense. The patient was successfully treated with 12 weeks of clarithromycin and levofloxacin treatment. Mass spectrometry is the latest microbial diagnostic method; however, it cannot be used to identify M. ulcerans subsp. shinshuense. To accurately detect this enigmatic pathogen and uncover its epidemiology and clinical characteristics in Japan, more accumulation of clinical cases with accurate identification of the causative pathogen is essential.

The worldwide spread of tick-borne diseases (TBDs) has become a public health concern. Therefore, this study aimed to clarify trends in the incidence of Japanese spotted fever (JSF), one of Japan's most prevalent TBDs. Weekly infectious disease reports were used to calculate the annual incidence rates (AIRs) of JSF. Data were stratified by age and sex, and joinpoint regression analysis was performed to estimate the annual percentage change (APC). AIR and APC were geographically compared among the 47 prefectures. A total of 3,453 JSF cases were observed from 2001 to 2020. The AIR per 100,000 population was 0.03 in 2001, which increased approximately 10-fold to 0.33 in 2020. The average APC (AAPC) during the study period was 12.3% (95% CI: 10.7-13.9). By age group, the incidence of JSF increased more rapidly among the older population: 11.5% (95% CI: 10.1-12.9) in those aged ≥ 65 years and 8.9% (95% CI: 6.4-11.5) in those aged < 50 years. Although the AIR over the past two decades was higher in climatically warm regions located in southwestern Japan and on the Pacific coast, increases in the AAPC were notable in colder regions located in eastern Japan. The incidence of JSF continues to increase in Japan, especially among older populations and in eastern prefectures, where the disease has not been previously diagnosed.
