Cytomegalovirus (CMV) colitis, which is rare in an immunocompetent patient, was encountered in a 67-year-old man who was admitted due to persistent diarrhea. The first diagnostic tool was colonoscopy, which showed multiple ulcers from cecum to rectum. The secondary tool was CMV polymerase chain reaction, and CMV colitis was diagnosed. Intravenous ganciclovir therapy was administered, which resulted in improvement of diarrhea and ulcers throughout the colon were healed. Asymptomatic colon perforation was detected during diagnostic testing, which improved over the conventional treatment. CMV colitis is rare in immunocompetent patients, but it is essential for the differential diagnosis.

Gastrointestinal (GI) bleeding is a rare adverse event of dasatinib, which is known to be caused by dasatinib-induced colitis, severe thrombocytopenia, and platelet dysfunction. We present two cases of pediatric patients who developed hematochezia during treatment with dasatinib after hematopoietic stem cell transplantation (HSCT). A colonic tissue biopsy was performed to differentiate the cause of GI bleeding. Both patients were diagnosed with proven cytomegalovirus (CMV) colitis, but only one was treated with ganciclovir. The patient who did not receive antiviral therapy experienced recurrent GI bleeding during dasatinib administration, leading to multiple treatment interruptions. During dasatinib therapy after HSCT, patients with GI bleeding and confirmed CMV colitis may benefit from antiviral therapy to reduce interruptions in dasatinib therapy.

We report a pediatric patient admitted with abdominal pain, diffuse lower extremity edema and watery diarrhea for two months. Laboratory findings including complete blood count, serum albumin, lipid and immunoglobulin levels were compatible with protein losing enteropathy. Colonoscopic examination revealed diffuse ulcers with smooth raised edge (like "punched out holes") in the colon and terminal ileum. Histopathological examination showed active colitis, ulcerations and inclusion bodies. Immunostaining for cytomegalovirus was positive. Despite supportive management, antiviral therapy, the clinical condition of the patient worsened and developed disseminated cytomegalovirus infection and the patient died. Protein losing enteropathy and disseminated cytomegalovirus infection a presenting of feature in steroid-naive patient with inflammatory bowel disease is very rare. Hypogammaglobulinemia associated with protein losing enteropathy in Crohn's disease may predispose the cytomegalovirus infection in previously healthy children.

Adult T-cell leukemia/lymphoma (ATLL) is a malignancy of mature T-cells caused by the human T-cell lymphotrophic virus type I (HTLV-D. HTLV-I is endemic in some areas in Japan, the Caribbean basin, and Africa but has low prevalence in South Korea. Patients with ATLL are susceptible to opportunistic infections such as cytomegalovirus (CMV) infection, but CMV infection in chronic ATLL is uncommon. Reported herein is a case involving a 44-year-old woman with chronic ATLL who presented the symptoms of fever and diarrhea. She was suspected to have acute-type ATLL but was later diagnosed with CMV colitis.

Treatment guidelines for postnatal cytomegalovirus (pCMV) infection in preterm have not been established yet. Neutropenia, thrombocytopenia, hepatitis, colitis, and sepsis-like disease are among the clinical manifestations, which range from moderate to serious. We present a case of autopsy diagnosed as pCMV infection in a premature infant delivered at gestational age of 24 weeks and 5 days. On the 7th and 14th days of birth, urinary CMV polymerase chain reaction samples were negative, ruling out congenital CMV infection. However, autopsy examination revealed that the patient had disseminated pCMV infection. CMV inclusion bodies were found in the majority of tissues, including the lung, liver, pancreas, breast, kidney, and adrenal gland, but not the placenta. The thymus exhibited significant cortical atrophy and T-cell immunodeficiency, possibly induced by dexamethasone treatment for bronchopulmonary dysplasia or by pCMV infection itself. If dexamethasone treatment is extended or high doses are considered, it may be beneficial to test the CMV infection status to prevent aggravation of infection. This case demonstrates that, despite the low prevalence, pCMV infection should be considered a differential diagnosis in preterm if other conditions or etiology cannot justify clinical deterioration.

배경: 폐 이식 수술 후 관리가 급속하게 발전함에도 불구하고 이식 후 소화기계 합병증은 여전히 중요한 문제점으로 남아있다. 저자들은 폐 이식 후 발생한 소화기계 합병증과 그의 치료법에 대해 후향적으로 연구하였다. 대상 및 방법: 1996년 7월부터 2009년 3월까지 23명의 환자에서 시행한 25예의 폐 또는 심폐이식에 대한 의무 기록을 검토하였다. 소화기계 합병증은 폐 이식 후 발생한 소화기계 질환으로 정의 하였다. 30일내 사망한 8명의 환자는 연구에서 제외하였다. 결과: 추적 관찰 기간은 중앙값 6.9개월(범위: 2개월 부터 111개월)로 수술 사망을 제외한 17예 중 11예(64.7%)에서 23회의 소화기계 합병증이 발생하였다. 만성 위염이 17예 중 4예(23.5%)에서 발생하여 가장 많았고, 2주 이상의 심한 설사가 3예에서 발생하였다. 3예에서 위궤양이 있었고 이중 1명의 환자는 궤양으로 인한 위천공으로 위 봉합술을 시행 받았다. 또한, 이 환자는 복부 수술 후 2개월 만에 궤양이 재발하여 위 출혈이 발생하였다. Cytomegalovirus에 의한 위염과 식도염이 각각 2예와 1예 있으며 식도 궤양은 2예 있었다. 식도 협착은 2예가 있었는데 스텐트를 삽입하여 치료하였다. 그밖에 장폐쇄, 황달을 동반한 담석, 위막성 대장염(pseudomembranous colitis), 내시경하 점막 절제술로 치료한 조기 위암이 각각 1예씩 있었다. 결론: 폐 이식 후 발생하는 소화기계 합병증은 발병률이 비교적 높은 편이며 폐 이식 후 환자의 영양 상태를 악화시켜 이환율과 사망률을 높이는 결과를 가져올 수 있기 때문에 적극적인 검사를 통한 조기 진단과 치료가 필요하다.
