리툭시맙(Rituximab)은 CD20에 대한 키메라형 IgG1 단클론 항체로 스테로이드 의존성 또는 난치성 신증후군에 대한 새로운 치료약제로 이용되고 있다. 그러나 리툭시맙의 약제 부작용에 대해서는 아직까지 더 많은 연구가 필요하다. 저자들은 스테로이드 의존성 신증후군을 앓고 있던 9세 남아에서 수차례의 리툭시맙 사용 후 기쿠치병(Kikuchi-Fujimoto disease)이 병발한 증례를 보고하는 바이다. 기쿠치병은 자연 회복의 양성 경과를 보이는 조직구 괴사성 림프절염으로 아직 원인은 알려져 있지 않다. 이 증례에서는 환자의 말초 혈액 B 면역세포 수치가 매우 감소되었을 때 발병하였으며, 이후 환자의 B 면역세포가 회복되면서 서서히 자연 소실되었다. 이 증례는 비록 병리 조직학적 진단은 뒷받침되지 못하였지만 임상적으로 진단된 기쿠치병이 리툭시맙 사용의 부작용으로 발생할 수 있다는 연관성을 시사하는 첫 번째 보고로써, 소아 신증후군에서 리툭시맙 사용의 안전성에 대한 이해의 폭을 넓히고자 하였다.

Community acquired pneumonia(CAP) is the most prevalent disease among pneumonia patients and progressed to severe pneumonia. A retrospective study was performed to evaluate antibiotic regimens according to guidelines of Infectious Disease Society of America. From January to October 2005, chart review of 50 patients with CAP was peformed in terms of microbiology and laboratory data of each regimen. Temperature, WBC count, ALT, AST and alkaline phosphatase of each patient were examined for liver toxicity. In three patients received levofloxacin appeared to have normalized temperature and improved cough. The patients who received cefmetazole -aminoglycoside appeared to have worsen LFT(Liver function test). Many patients in flomoxef-aminoglycoside group received mechanical ventilation because of the basis diseases like tuberculosis, diabetes mellitus and hypertension. In conclusion, antibiotic therapy for the treatment of CAP should be selected according to tolerance, bacteria and severity of disease.

Background: Chronic lymphoid leukemia (CLL) is the most frequent type of adult leukemia. The Rai and Binet staging systems have been well recognized as standards for assessing the treatment requirements and overall survival in CLL patients. However, there is a need to seek newer prognostic markers to identify stable or progressive forms of CLL that will facilitate risk-adapted treatment strategies. Currently a molecular biomarker ZAP-70 has attracted interest as providing prognostic information in CLL patients. Objective: To determine the frequency of ZAP-70 positivity in B-CLL patients at disease presentation. Materials and Methods: From January 2011 to September 2014, 89 patients were diagnosed to have chronic lymphoid leukemia. Complete blood count was done on an automated analyzer (Cell Dyne, Abott Architect, USA), while immunophenotyping was conducted for each patient to establish the diagnosis of the disease. ZAP-70 expression was evaluated by flow cytometry. Data were compiled and analyzed by SPSS version 21. Results: Out of the total of 89 B-CLL patients, 62 (69.7%) were male and 27 (30.3%) were females with a male to female ratio of 2:1. The mean age was $57.5{\pm}12.1years$. The frequency of ZAP-70 positivity in our B-CLL patients was found to be 13.5%. ZAP-70 positivity was significantly correlated with stage III disease and high absolute lymphocytic count (P<0.05). No correlation of ZAP-70 could be established with age and gender (p>0.05). Conclusions: The frequency of ZAP-70 in our patients appears low. It is approximately half that in international data. We would recommend to screen all the newly diagnosed patients with CLL for ZAP-70 protein expression for risk stratification, family counseling and to predict overall survival.

Purpose: This study investigated predictors of unresponsiveness to second-line intravenous immunoglobulin (IVIG) treatment for Kawasaki disease (KD). Methods: This was a single-center analysis of the medical records of 588 patients with KD who had been admitted to Asan Medical Center between 2006 and 2014. Related clinical and laboratory data were analyzed by univariate and multivariate logistic regression analyses. Results: Eighty (13.6%) of the 588 patients with KD were unresponsive to the initial IVIG treatment and received a second dose. For these 80 patients, univariate analysis of the laboratory results obtained before administering the second-line IVIG treatment showed that white blood cell count, neutrophil percent, hemoglobin level, platelet count, serum protein level, albumin level, potassium level, and C-reactive protein level were significant predictors. The addition of methyl prednisolone to the second-line regimen was not associated with treatment response (odds ratio [OR], 0.871; 95% confidence interval [CI], 0.216-3.512; P=0.846). Multivariate analysis revealed serum protein level to be the only predictor of unresponsiveness to the second-line treatment (OR, 0.160; 95% CI, 0.028-0.911; P=0.039). Receiver operating characteristic curve analysis to determine predictors of unresponsiveness to the second dose of IVIG showed a sensitivity of 100% and specificity of 72% at a serum protein cutoff level of <7.15 g/dL. Conclusion: The serum protein level of the patient prior to the second dose of IVIG is a significant predictor of unresponsiveness. The addition of methyl prednisolone to the second-line regimen produces no treatment benefit.

Purpose: This study examined the factors affecting the treatment of diabetes mellitus foot patients who had undergone a Syme amputation. Materials and Methods: This study included 17 patients diagnosed with a diabetes mellitus foot and who had undergone a Syme amputation from January 2010 to January 2014. Some of the risk factors (age, body mass index [BMI], disease duration, smoking, ankle brachial index [ABI], HbA1c, serum albumin, total lymphocyte, C-reactive protein [CRP], and serum creatine) that affect the successful Syme amputation were analyzed. Results: The healing rate of a Syme amputation was significantly higher when the lymphocyte count was above $1,500mm^3$ (p=0.029). The factors affecting the surgical outcome according to multivariate analysis were HbA1c and the BMI (p=0.014, p=0.013). Regarding reamputation, there was a significant difference with HbA1c, lymphocyte, and BMI (p=0.01, p=0.03, and p=0.01). No significant differences were observed with age, disease duration of diabetes mellitus, smoking, ABI, serum albumin, CRP, and serum creatine. Conclusion: The HbA1c level, BMI and total lymphocyte count are risk factors that must be considered for successful Syme amputation in patients with diabetic foot disease.

Background: Most patients with influenza recover spontaneously or following treatment with an anti-viral agent, but some patients experience pneumonia requiring hospitalization. We conducted a retrospective review to determine the incidence and risk factors of pneumonia in hospitalized patients with influenza A or B. Methods: A total of 213 patients aged 18 years or older and hospitalized with influenza between January 2012 and January 2015 were included in this study. A reverse-transcriptase polymerase chain reaction assay was used to detect the influenza A or B virus in the patients' sputum samples. We collected demographic and laboratory data, combined coexisting diseases, and radiologic findings. Results: The incidence of pneumonia was higher in patients in the influenza A group compared to those in the influenza B group (68.6% vs. 56.9%), but this difference was not statistically significant. The presence of underlying respiratory disease was significantly associated with pneumonia in the influenza A group (adjusted odds ratio [OR], 3.975; 95% confidence interval [CI], 1.312-12.043; p=0.015). In the influenza B group, the white blood cell count (adjusted OR, 1.413; 95% CI, 1.053-1.896; p=0.021), platelet count (adjusted OR, 0.988; 95% CI, 0.978-0.999; p=0.027), and existence of an underlying medical disease (adjusted OR, 15.858; 95% CI, 1.757-143.088; p=0.014) were all significantly associated with pneumonia in multivariate analyses. Conclusion: The incidence of pneumonia was 65.7% in hospitalized patients with influenza A or B. The risk factors of pneumonia differed in hospitalized patients with influenza A or B.

연구배경: 기관지폐포세척술로 얻은 기관지폐포세척액의 총세포 숫자와 감별숫자는 특발성폐섬유증을 포함한 간질성 폐질환의 진단과 예후 및 치료방침의 결정에 유용한 검사방법이다. 그러나 기관지폐포세척액 처리 방법에 대한 표준 방법 (standard method)이 아직 정립되어 있지 않고, 병원마다 처리 방법이 상이한 경우가 많아 검사 결과의 해석에 어려움이 많은 실정이다. 이에 본 연구에서는 기관지폐포세척액의 처리방법 중에서 면거즈 (cotton gauze)로 걸르는 방법, 세척액의 원심 분리 후 재부유하는 방법, 기관지폐포세척액의 보관 시간등이 총세포숫자와 감별숫자에 미치는 영향을 관찰하였다. 방 법: 활동성 폐질환이 없는 6명의 사람에 대해서 기관지내시경을 하여 얻은 기관지폐포세척액을 모아서 siliconized glass tube에 분주한 후, 0, 1, 2, 4겹의 면거즈 (pore size: 1mm)로 걸른후 일부를 trypan blue로 염색한 후 hemocytometer로 총세포숫자를 계수하고 일부는 cytocentrifuge한 후 Wright-Giemsa stain을 하여 감별숫지를 하였다. 그리고 일부의 세척액을 두 겹의 거즈로 걸른 후에 원심분리(400g, 30min) 하고 RPMI1640으로 재부유액을 만들어 총세포숫자와 감별숫자를 하였다. 그리고 나머지는 $4^{\circ}C$ 냉장고에 보관하였다가 2시간, 24시간, 48시간 후에 각각 같은 방법으로 총세포숫자와 감별숫자를 하였다. 결 과: 기관지폐포세척액을 면거즈로 거르지 않은 경우와 여러겹의 면거즈로 걸른 경우 총세포숫자와 감별숫자에 차이가 없었으나 기관지폐포세척액을 면거즈로 거르지 않았을 경우 두 예(33%)에서 점액사 때문에 세포가 뭉치고 겹쳐져서 총세포숫자와 감별숫자가 어려웠다. 기관지폐포세척액을 원심분리하였을 경우 총세포숫자는 감소하였으나 ($24{\pm}18%$), 감별숫자에는 차이가 없었다. 보관시간에 따른 총세포숫자에 있어서 2시간 보관했을 경우에는 총세포숫자의 감소가 없었으나 24시간 이상 보관시 유의하게 감소하였으며 (24시간: $28{\pm}21%$, 48시간: $41{\pm}24%$), 감별숫자에 있어서는 보관시간에 따른 차이는 없었으나 48시간 보관시에는 세포변성으로 감별숫자가 어려웠다. 결 론: 기관지폐포세척액의 총세포숫자와 감별숫자를 위한 기관지폐포세척액의 처리과정에서 면거즈로 걸러서 두시간 아내에 처리하는 것이 좋으며 원심분리는 하지 않는 것이 좋을 것으로 생각된다.

Background: Essential thrombocythemia (ET) is a clonal hemopoietic stem cell myeloproliferative neoplasm characterized by persistent thrombocytosis along with megakaryocytic hyperplasia. In the last decade following the identification of an acquired JAK2 V617F mutation, there has been acceleration in our understanding of this disease. The rational of this study was to determine the mutational profile of JAK2 V617F in Pakistan patients with ET. Materials and Methods: In this retrospective cross sectional study, 21 patients with ET were enrolled from January 2011 to December 2014. Patients were diagnosed based on WHO criteria for essential thrombocythemia. Complete blood count was done on an automated hematology analyzer, while JAK2 V617F expression was evaluated by polymerase chain reaction. Results: The mean age was $56.7{\pm}19.0$ years (range 18-87) and the male to female ratio was 1:1.1. The frequency of JAK2 V617F positivity in our ET patients was found to be 61.9%. The mean hemoglobin was $11.7{\pm}2.4$ g/dl with a total leukocyte count of $13.3{\pm}8.1{\times}109/l$ and a platelet count of $1188{\pm}522{\times}109/l$. Positive correlations for JAK2 V617F mutation were established with high TLC count and raised LDH (P<0.05). No correlation of JAK2 V617F could be established with age and gender (P>0.05). Conclusions: JAK2 V617F mutation frequency in our ET patients was similar to those reported previously. Screening for the mutation in all suspected essential thrombocythemia cases could be beneficial in differentiating patients with reactive and clonal thrombocytosis.
