        중증열성혈소판감소증후군

        김계형 ( Kye Hyung Kim ),오명돈 ( Myoung Din Oh ) 대한내과학회 2014 대한내과학회지 Vol.86 No.3

        Severe fever with thrombocytopenia syndrome (SFTS) is firstly reported in China in 2011. It is an emerging infectious disease in China, Japan and South Korea. It is caused by novel bunyavirus, called SFTS virus. The vector of SFTS is Haemaphysalis longicornis tick and domesticated animals may serve as intermediate hosts. The clinical manifestations of SFTS are fever, vomiting, diarrhea, thrombocytopenia and leukopenia. In severe cases, multiple organ failure, disseminated intravascular coagulopathy, and central nervous systems manifestation are present. The case-fatality rate is 6-30%. There is no effective antiviral therapy and supportive care is the main treatment.

        국립공원 종사자의 중증열성혈소판감소증후군 혈청유병률 및 위험요인

        김동휘(Dong-Hwi Kim),김계형(Kye-Hyung Kim),이종윤(Jongyoun Yi),고미경(Mee Kyung Ko),박성준(Sung-Jun Park),유석주(Seok-Ju Yoo),이관(Kwan Lee),박지혁(Ji-Hyuk Park) 한국농촌의학 지역보건학회 2021 농촌의학·지역보건 Vol.46 No.3

        이번 연구는 임업 종사자 중 하나인 국립공원 종사자를 대상으로 진드기 매개 감염병인 SFTS 혈청유병률을 확인하고 관련된 위험요인을 조사하고자 시행하였다. 2016-2017년에 실시한 “쯔쯔가무시증 및 라임병 고위험군에 대한 감염실태 조사” 사업으로 수집된 763명의 혈청 검체와 설문조사 결과를 이용하였고, 혈청분석은 Double-antigen sandwich enzyme-linked immunosorbent assay로 IgG와 IgM을 포함한 전체 항체를 검사하였다. 국립공원 종사자 763명의 SFTS 혈청유병률은 1.4%였다. 일반적 특성 중 성별로는 여성이 1.7%로 더 높았고, 연령별로는 30-49세에서 2.0%로 가장 높았다. 학력에 따라 고등학교 졸업 이하가 2.5%로 더 높았고, 기관별로는 국립공원사무소 분소 및 기타기관이 1.7%로 더 높았다. 근무기간에 따라 15년 이상이 2.2%로 가장 높았으며, 지역적으로는 북부에서 3.1%로 가장 높았다. 다변량 로지스틱 회귀분석 결과 학력, 탐방 프로그램 운영, 매일 작업복을 갈아입음이 최종 모델에 포함되었다. 이 중 탐방 프로그램을 운영할 경우는 교차비가 3.48(95% 신뢰구간=1.01-12.01)로 통계적으로 유의하게 높았다. 학력과 매일 작업복을 갈아입음은 통계적으로 유의하지 않았다. 이번 연구는 진드기에 노출될 수 있는 고위험 직업군인 국립공원 종사자를 대상으로 SFTS의 혈청유병률을 파악하기 위한 조사를 국내에서 최초로 시행하였다는 점에서 의미가 크다. 국립공원 종사자는 진드기 매개 감염병의 고위험 직업군임에도 불구하고 작업 중 SFTS 예방을 위한 작업환경 및 습관과 관련된 예방활동이 부족한 것으로 생각되며, 국립공원 종사자에 대한 체계적인 예방 교육 및 훈련을 보다 강화할 필요가 있다. Objectives: This study was carried out to understand the seroprevalence and risk factors for severe fever with thrombocytopenia syndrome (SFTS) among the Korea National Park Service (KNPS) workers. Methods: We used the stored serum samples (763) and survey results collected from the previous investigation on scrub typhus and Lyme disease among the KNPS workers during 2016-2017. The serum samples were analyzed by double-antigen sandwich enzyme-linked immunosorbent assay, which was used to test the total antibody including IgG and IgM. Results: The SFTS seroprevalence among the KNPS worrkers was 1.4%. In multivariate logistic analysis, the national park exploration programs (odds ratio, 3.48; 95% confidence interval, 1.01-12.01) was significantly associated with the seroprevalence of SFTS. Conclusion: This study was the first serological study of SFTS among forestry workers in South Korea. Although the KNPS workers are at a high-risk group of SFTS, the prevention activities related to the working environment and habit was insufficient. Thus, systematic prevention education and training for the KNPS workers need to be strengthened.

        Vancomycin frequently induces hypersensitivity reactions including red man syndrome (RMS) and anaphylaxis. Lowering infusion rate with antihistamine premedication is usually effective to reduce RMS, however, desensitization should be considered for severe reactions not responding to usual measures. Here, we report a case of a patient with pyogenic spondylitis who had developed hypersensitivity reaction to vancomycin, got a full recovery with vancomycin desensitization. A 63-year-old man was transferred to our hospital for back pain, proved to pyogenic spondylitis. As methicillin-resistant Staphylococci aureus infection was suspected, vancomycin was administrated. But, he showed hypersensitivity reactions such as hypotension, dyspnea and severe flushing after vancomycin administration at previous hospital. Readministration of vancomycin at a lower infusion rate with premedication was tried. Three hours after vancomycin infusion, he developed fever, chills, rash and hypotension. Thrombocytopenia was occurred after administration of other antibiotics including cefazolin and teicoplanin. Vancomycin administration was attempted according to a rapid desensitization protocol. The infusion rate of vancomycin was increased to the standard rate. After the desensitization, he successfully completed the full course of treatment with vancomycin. Vancomycin desensitization could be the option for the vancomycin hypersensitivity when other antibiotics are not feasible.

        Diabetic foot infection is one of the important complications in patients with advanced diabetes mellitus. Limb threatening infections such as osteomyelitis, abscess, and necrotizing fasciitis are frequently accompanied by the disease. Non-tuberculous mycobacterium (NTM) is a rare causative organism of diabetic foot infection. Thus, if one is not suspicious or meticulous, infection due to NTM will be easily overlooked and this will result in delayed diagnose and treat. Therefore, it is necessary to consider NTM as the causative organism if the wound does not respond to the conventional antibiotic treatment and the culture from the adequately obtained specimen reveals atypical acid-fast bacilli. We present a case of diabetic foot infection with osteomyelitis and abscess due to Mycobacterium mageritense, one of the rapid growing mycobacteria, that was successfully treated with surgical debridement and appropriate antibiotic treatment.

        Infectious diseases imported from other countries have increased as more and more Koreans are going abroad for various purposes. Tsutsugamushi disease from other endemic area such as Southeast Asia is important, because it can occur in any season and eschar may be absent. We report a case of imported tsutsugamushi disease acquired in the Philippines. A patient presented with fever, headache, and maculopapular skin rash. However, eschar was absent. Polymerase chain reaction (PCR) for 56-kDa gene of Orientia tsutsugamushi using buffy coat was positive. Serum indirect immunofluorescent antibody assay was initially negative but became positive with a titer of 1:320 at follow-up, Sequencing analysis revealed the strain to be 100% identical to the TW73R strain identified in Taiwan. After the patient received doxycycline, body temperature normalized in 12 hours. Tsutsugamushi disease is one of the differential diagnoses that should be included for patients with fever who have recently returned from Southeast Asian countries. PCR for O. tsutsugamushi using patient's buffy coat was useful for early diagnosis.

        Toxoplasmosis is a rare but fatal complication in hematopoietic stem cell transplant recipients, usually associated with allogeneic hematopoietic stem cell transplantation (HSCT). We report a case of cerebral toxoplasmosis in a patient with multiple myeloma, following tandem autologous stem cell transplantation. A 55-year-old Korean male presented with weakness in both legs that had progressed to both arms. A magnetic resonance imaging scan of the brain revealed multiple, variablesized ring-enhancing lesions with surrounding edema in the cerebral hemispheres and brain stem. Stereotactic biopsy revealed bradyzoites of Toxoplasma gondii in the brain tissue. The patient received trimethoprim-sulfamethoxazole, followed by pyrimethamine and sulfadiazine, accompanying treatment for progressive multiple myeloma. Cerebral toxoplasmosis should be considered as one of the differential diagnoses in patients with neurologic signs following autologous HSCT.

        Background: Herpes zoster develops via reactivation of the latent varicella zoster virus (VZV) in neuronal ganglia as host immunity declines. In Korea, seroprevalence of VZV is very high and population at risk for herpes zoster is increasing. The goal of this study is to evaluate the infection rate of the VZV and the lifetime prevalence of herpes zoster, and to determine the genotype of VZV. Material and Method: Serum IgG antibody titer was measured in 399 patients. Lifetime prevalence of herpes zoster was evaluated through a survey of 2,054 participants. VZV was isolated by cell culture technique using MRC-5 cells. To determine the genotype of VZV, ORF 22, 38, 54, 62 were amplified by PCR, and after digestion of the PCR products with enzymes pst I, bgl I, and sma I, restrictionfragment- length-polymorphism (RFLP) was analysed. The amplified ORF 22 PCR product was sequenced and checked for single nucleotide polymorphisms. Results: The overall seroprevalence of VZV IgG in adults was 93.9% (375/399). The overall lifetime prevalence of herpes zoster was 13.7% (282/2,054). Of the patients with herpes zoster, 17.7% (50/282) of patients experienced postherpetic neuralgia for more than one month. All 22 VZV isolates were of J genotype; 21 (95.4%) isolates were all pstI^(+) bgl/I^(+) smaI^(-) and 1 (4.5%) isolate was pstI^(-) bgl/I^(+) smaI^(-) (pOka) genotype. Conclusions: The seroprevalece of VZV IgG antibody was 93.9% in adults. The lifetime prevalence of herpes zoster was 13.7%. The genotype of VZV isolated from adults over 60 years old were all of J genotype.

        반복적인 부비동염으로 내원한 Good 증후군 1예

        송경호,김계형,김충종,박경운,전상훈,김홍빈,김남중,오명돈,최강원 대한감염학회 2007 감염과 화학요법 Vol.39 No.5

        Good 증후군은 흉선종과 면역결핍이 동반되는 질환으로, B세포의 감소로 인한 범저감마글로불린혈증과 CD4^(+)T세포의 감소로 인한 세포성 면역저하가 동시에 나타나는 것을 특징으로 한다. 본 증례는 18개월 전부터 발생한 반복적인 부비동염을 주소로 내원한 43세 남자 환자로, 내원 1년 전 흉선종절제수술을 시행받았으며, 면역학적 검사상 범저감마글로불린혈증과 T세포의 감소 등의 이상 소견이 발견되었다. 정주 면역글로불린과 경험적 항생제(amoxicillin/clavulanic acid) 사용 후 부비동염이 호전되었으며, 예방접종과 정기적인 면역글로불린 투여 후 특이 합병증없이 경과 관찰 중이다. Good's syndrome is the association of thymoma with immunodeficiency, characterized by hypogammaglobulinemia, B-cell lymphopenia and variably defects in cellular immunity with CD4^(+) T-cell lymphopenia and an inverted CD4^(+):CD8^(+) T-cell ratio. We report a 43-year-old male patient who presented with a 18-month history of productive cough and postnasal drip. One year ago, he underwent the operation for resection of a thymoma. Despite of appropriate management, sinusitis relapsed multiple times. He was found to have hypogammaglobulinemia with nearly absent B cells(4/μL). The CD4^(+) T-cell count was 554/μL with an inverted CD4^(+):CD8^(+) T-cell ratio of 0.6. His symptoms and signs improved with antibiotic treatment and monthly administration of intravenous immunoglobulin (IVIG, 400 mg/kg).
