인체면역결핍바이러스 감염자의 페포자충폐렴 치료에 있어 보조적 스테로이드 치료의 효용성은 잘 알려진데 반해, 비인체면역결핍바이러스 면역저하자에서의 페포자충폐렴 치료에 있어서의 보조적 스테로이드 치료의 효용성은 논란의 여지가 있다. 본 연구자들은 비인체면역결핍바이러스 면역저하자인 중증복합면역결핍증 영아에서 이환된 중증페포자충폐렴를 치료하던 중 면역재구성염증증후군 유사현상을 관찰하였으며, 보조적 스테로이드 치료에 잘 반응하였기에 이를 보고하는 바이다.

크립토코쿠스 수막염 면역재구성 염증증후군은 역설적 크립토코쿠스 수막염 면역재구성 염증증후군과 증상이 드러나는 크립토코쿠스 수막염 면역재구성 염증증후군의 두 가지 형태가 있다. 역설적 크립토코쿠스 수막염 면역재구성 염증증후군과 크립토코쿠스 수막염 재발을 구별하는 것은 중요하다. 왜냐하면 면역재구성 염증증후군 없는 크립토코쿠스 수막염보다 면역재구성 염증증후군이 있는 크립토 코쿠스 수막염의 사망율이 더 높고, 역설적 크립토코쿠스 수막염 면역재구성 염증증후군과 크립토코쿠스 수막염 재발은 다른 치료를 요구하기 때문이다. 우리는 인간면역결핍바이러스 감염환자의 3년의 추적기간 동안 임상 소견과 자기공명영상 소견이 잘 대조된 역설적 크립토코쿠스 수막염 면역재구성 염증증후군의 사례와 감별에 도움이 되는 새로운 자기공명영상 소견을 보고하고자 한다.

In acquired immunodeficiency syndrome (AIDS) patients, immune reconstitution inflammatory syndrome (IRIS) due to Mycobacterium avium complex (MAC) infection is one of the most difficult IRIS types to manage. We report an unusual case of MAC-associated IRIS. At first the patient was diagnosed human immunodeficiency virus (HIV) infection after he was admitted with pneumocystis pneumonia. After starting antiretroviral therapy he presented unmasked IRIS with MAC infection. Next, he was hospitalized with continuous loose stools and new-onset fever. Investigation included computed tomography (CT), which showed homogeneous enhancement and enlargement of the lymph nodes (LN), elevation of ferritin (>1,650 ng/mL) and lactate dehydrogenase (306 IU/L) levels, and F- fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) scan, which showed increased FDG uptake. These findings were highly indicative of lymphoma. We performed laparoscopic biopsy of the mesenteric LN, and the biopsy culture grew MAC. So we made a diagnosis of MAC-associated. Therefore, IRIS must be considered as a possible diagnosis when AIDS patients develop new symptoms or exhibit exacerbations of existing symptoms. Furthermore the biopsies should be conducted.

Purpose: Lymphocyte subset recovery is an important factor that determines the success of hematopoietic stem cell transplantation (HSCT). Temporal differences in the recovery of lymphocyte subsets and the factors influencing this recovery are important variables that affect a patient's posttransplant immune reconstitution, and therefore require investigation. Methods: The time taken to achieve lymphocyte subset recovery and the factors influencing this recovery were investigated in 59 children who had undergone HSCT at the Department of Pediatrics, The Catholic University of Korea Seoul St. Mary's Hospital, and who had an uneventful follow-up period of at least 1 year. Analyses were carried out at 3 and 12 months post-transplant. An additional study was performed 1 month post-transplant to evaluate natural killer (NK) cell recovery. The impact of pre- and post-transplant variables, including diagnosis of Epstein-Barr virus (EBV) DNAemia posttransplant, on lymphocyte recovery was evaluated. Results: The lymphocyte subsets recovered in the following order: NK cells, cytotoxic T cells, B cells, and helper T cells. At 1 month post-transplant, acute graft-versus-host disease was found to contribute significantly to the delay of $CD16^+/56^+$ cell recovery. Younger patients showed delayed recovery of both $CD3^+/CD8^+$ and $CD19^+$ cells. EBV DNAemia had a deleterious impact on the recovery of both $CD3^+$ and $CD3^+/CD4^+$ lymphocytes at 1 year post-transplant. Conclusion: In our pediatric allogeneic HSCT cohort, helper T cells were the last subset to recover. Younger age and EBV DNAemia had a negative impact on the post-transplant recovery of T cells and B cells.
