사립체 근병증은 사립체 호흡 사슬의 장애로 인한 것으로 내분비계 관련 증상이 흔히 동반되고 그 중 당뇨병이 상대적으로 높은 빈도를 보인다고 알려져 있다. 사립체 근병증에서의 당뇨병은 사립체 기능 장애로 인한 인슐린 분비의 결함으로 발생하고, 대개 인슐린 의존성이나 당뇨병성 케톤산증으로 발현하거나 자가 항체가 검출되는 경우는 드물다. 저자들은 사립체 근병증 환자에서 당뇨병성 케톤산증으로 발현하고 Anti-GAD antibody와 Anti-insulin auto-antibody가 모두 양성으로 확인된 인슐린 의존성 당뇨병을 진단하였기에 이를 기존의 문헌과 비교하여 보고하는 바이다.

The Guillain-Barre Sydrome (GBS) is post-infectious autoimmune disease and it could be caused by auto-antibodies produced after infections. Mycoplasma pneumoniae is one of rare cause of GBS and known to be associated with antibody to galactocerebroside (GalC) which is a major neutral glycolipid constituent of myelin. We report a case of GBS with immunoglobulin M GalC antibody after M. pneumoniae infection.

We present an 8 years old girl who was diagnosed at 6 months of age of Progressive Familial Intrahepatic Cholestasis type 2. Although liver transplantation (LT) was classically considered curative for these patients, cholestasis recurrence with normal gamma-glutamyl transpeptidase (GGT), mediated by anti-bile salt export pump (BSEP) antibodies after LT (auto-antibody Induced BSEP Deficiency, AIBD) has been recently reported. Our patient underwent LT at 14 months. During her evolution, patient presented three episodes of acute rejection. Seven years after the LT, the patient presented pruritus with cholestasis and elevation of liver enzymes with persistent normal GGT. Liver biopsy showed intrahepatic cholestasis and giant-cell transformation with very low BSEP activity. Auto-antibodies against BSEP were detected therefore an AIBD was diagnosed. She was treated with Rituximab and immunoadsorption with resolution of the AIBD. As a complication of the treatment she developed a pneumocystis infection successfully treated with corticoids, cotrimoxazol and anidulafungin.

Aim: The aim of this study was to investigate the frequency and correlation between auto-antibodies to survivin and MUC1 variable number tandem repeats (VNTR) in colorectal cancer (CRC), which can provide valuable information for the design of immunotherapeutic vaccines for this disease. Methods: Enzyme-linked immunosorbent assays (ELISA) were used to examine the level of auto-antibodies against survivin and MUC1 VNTR in the serum of 135 CRC patients and 95 healthy volunteers. Results: Using mean absorbance + 2 standard deviations (SD) of the healthy samples as a cut-off value, the positive rates of survivin and MUC1 VNTR auto-antibodies in CRC were 31.1% and 18.5%, respectively. Altogether, the survivin and MUC1 VNTR positive samples accounted for 36.3% of the CRC patients, and 7.4% were positive for both. Conclusion: A significant positive correlation was found between levels of specific antibodies against survivin and MUC1 VNTR in the serum of CRC patients (r = 0.3652, P < 0.0001), suggesting that vaccines against both targets would elicit immune responses more effectively.

Although high-dose chemotherapy and autologous stem cell transplantation (HDCT/autoSCT) have improved the prognosis for patients with high-risk neuroblastoma (NB), event-free survival rates remain in the range of 30 to 40%, which is unsatisfactory. To further improve outcomes, several clinical trials, including tandem HDCT/autoSCT, high-dose $^{131}I$-metaiodobenzylguanidine treatment, and immunotherapy with NB specific antibody, have been undertaken and pilot studies have reported encouraging results. Nonetheless, about half of high-risk NB patients still experience treatment failure and have no realistic chance for cure with conventional treatment options alone after relapse. Therefore, a new modality of treatment is warranted for these patients. In recent years, several groups of investigators have examined the feasibility and effectiveness of reduced-intensity allogeneic stem cell transplantation (RI alloSCT) for the treatment of relapsed/progressed NB. Although a graft-versus-tumor effect has not yet been convincingly demonstrated in the setting of relapsed NB, the strategy of employing RI alloSCT has provided hope that treatment-related mortality will be reduced and a therapeutic benefit will emerge. However, alloSCT for NB is still investigational and there remain many issues to be elucidated in many areas. At present, alloSCT is reserved for specific clinical trials testing the immunomodulatory effect against NB.

Objectives : The aim of this study was to know the immunity reponse of Esubwhaltong-tang(hereafter referred to ESWTT) to rheumatoid arthrits in CIA(collagen induced arthritis) mice. Methods : For this purpose, ESWTT was orally administerd to mice with arthritis induced by collagen II and then value of immunocyte in paw joint, cytokine(IL-6, $TNF-{\alpha}$), rheumatoid factor(IgG and IgM) and collagen II specific antibody in the serum were measured. Results : 1. The cytotoxicity was not shown on hFLSs and liver. 2. Marginal erosion, necrotic chodrocytes, cartilage and bone degradation were improved in histological section of paw joints from CIA mice(ESWTT extract administration group). 3. Total cell number of paw joint in CIA mice(ESWTT extract administration group) was decreased significantly. 4. The absolute number of CD3+, CD3+/CD69+, CD4+, CD4+/CD25+, CD49b+, CD3+/CD49b+ cells in CIA mice(ESWTT extract administration group) were decreased significantly. 5. The levels of IL-6 and $TNF-{\alpha}$ in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 6. The levels of total IgG and IgM in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 7. The level of collagen II specific antibody in the serum of CIA mice(ESWTT extract administration group) was decreased significantly. Conclusions : Comparison of the results for this study showed that ESWTT had immunomodulatory effects of suppressing. So we expect that ESWTT could be used as an effective drugs for not only rheumatoid arthritis but also auto-immune disease.

Anti double-stranded DNA (Anti-ds DNA)항체의 검출은 SLE의 진단에 중요하며 American College of Rheumatologists의 SLE 진단기준에 포함되어 있다. 또한 SLE 질병의 활성도와 Anti-ds DNA 항체 수준의 상관성이 보고되어 있으며 Anti-ds DNA 항체 정량검사는 SLE의 치료 전, 후 추적에 매우 유용하다. Anti-ds DNA 항체의 검출을 위한 검사 방법으로 방사면역측정법(radioimmunoassay, RIA)을 이용한 Farr assay, Crithidia luciliae를 이용한 면역형광 측정법(immunofluorescence Test, CLIFT), 효소면역측정법(enzyme-linked immunosorbent assay, ELISA), 화학발광면역 측정법(chemiluminescence immunoassay, CLIA)이 있다. 본원에서 방사면역측정법(radioimmunoassay, RIA)으로 Anti-ds DNA 항체 검사 과정에서 lipemic한 검체의 경우 침전물의 형성이 원활하지 않거나 침전물도 같이 흡입되는 상황이 발생 하였고, 이러한 문제점을 해결하기 위해 lipemic 검체가 분석 결과에 미치는 영향 정도를 평가하였다. 2012년 9월부터 2013년 2월까지 Anti-ds DNA 항체 검사가 의뢰된 검체 중 lipemic한 검체(n=81)를 선택하여 마이크로 원심분리기로 전처리(고속 원심분리: 14,000 rpm 5 mins)한 후 동시에 Anti-ds DNA 항체 검사(Anti-ds DNA kit, Trinity Biotech, Ireland)를 시행하였다. 실험군 1 (lipemic 검체의 Anti-ds DNA 항체 농도 ${\leq}7IU/mL$)에서 y=0.3636x+4.7322, $R^2=0.0238$, Pearson 상관계수는 0.154, paired t-test (P=0.003), Difference (%) mean 65.7의 결과를 얻었으며 통계적으로 유의한 차이를 보였다. 그러나 실험군 2 (lipemic 검체의 Anti-ds DNA 항체 농도 ${\geq}8IU/mL$)에서 y=0.9837x+0.2982, $R^2=0.994$, Pearson 상관계수는 0.997, paired t-test (P=0.181), Difference (%) mean -5.53을 보였고 통계적으로 유의한 차이가 없음을 확인할 수 있었다. 임상에서 SLE (systemic lupus erythematosus)의 진단에 중요한 역할을 하는 Anti-ds DNA 항체 검사는 lipemic 검체의 영향을 배제하기 위해서 반드시 전처리(고속 원심분리: 14,000 rpm 5 mins) 과정을 통해 혈청 내 지질 성분을 제거한 후 검사를 시행하여야 한다.

A 65-year-old woman was admitted due to poor oral intake and a dry cough over the previous 3 months. The physical examination was remarkable for bibasilar crackles, and plain chest radiography showed reticulation in both lower lung fields. A pulmonary function test demonstrated a restrictive pattern with a reduced diffusing capacity of the lung for carbon monoxide. High resolution computed tomography showed reticulation and honey-combing in both peripheral lung zones, which was consistent with usual interstitial pneumonia pattern. Her skin showed livedo reticularis. The erythrocyte sedimentation rate and C-reactive protein level were elevated, and hematuria was noted on urinary analysis. A serologic test for auto-antibodies showed seropositivity for Myeloperoxidase-Anti-neutrophil cytoplasmic antibody (MPO-ANCA). A kidney biopsy was performed and showed focal segmental glomerulosclerosis. She was diagnosed as having pulmonary fibrosis with microscopic polyangiitis (MPA) and treated with high dose steroids. Here we report a case of pulmonary fibrosis coexistent with microscopic polyangiitis.
