  • 골육종 환자에서 항암 화학요법 후 후기 합병증으로 발생하는 이차성 급성 골수성 백혈병은 드물지만 본 교실에서 한 증례를 경험하였기에 이를 보고하고자 한다. 1995년부터 1999년까지 골육종 진단후 항암 화학요법을 받은 77명의 환자중에서 이차적으로 발생한 급성 골수성 백혈병 1례를 경험하였고 이를 다른 문헌과 비교하여 원인 및 결과를 분석하였다. 17세 남자로 대퇴골 원위부의 골육종으로 진단받고 항암 화학요법 완료 후 28개월만에 환자의 혈액화학 검사상 백혈구의 심한 증가(20만개 이상)와 혈소판 감소를 보였고 골수 흡인생검 및 말초 혈액 도말 검사에서 단구양 미성숙 세포(monocytoid immature cell) 와 아세포(blast) 및 전단구 세포(promonocyte)의 심한 증가를 보여 항암 화학요법 후 이차적으로 발생한 급성 골수성 백혈병(AML M4)으로 진단하게 되었다. 항암화학 요법후 이차적으로 발생하는 급성 골수성 백혈병은 그 발생빈도는 미미하지만 조기 진단 및 치료가 이뤄지지 않으면 높은 이환률과 치사율을 보이는 치명적인 질환이며 발생가능성을 충분히 인식하고 항암 화학요법후 주기적 추시 관찰 및 적절한 검사 그리고 발병시 신속한 치료가 필요할 것으로 판단 된다.

  • 대혈관 혈관염은 대동맥과 이것의 주요 분지의 혈관벽에 만성 염증이 생기는 질환으로써 면역 이상반응에 의한 것이다. 혈액암은 이차적인 혈관염의 아주 드문 원인 중 한 가지다. 우리는 일차성 혈관염을 모방한 급성 골수성 백혈병과 연관된 드문 형태의 대혈관 혈관염에 대해서 보고하고자 한다.

  • Somatic RUNX1 mutations are found in approximately 10% of patients with de novo acute myeloid leukemia (AML), but are more common in secondary forms of myelodysplastic syndrome (MDS) or AML. Particularly, this applies to MDS/AML developing from certain types of leukemia-prone inherited bone marrow failure syndromes. How these RUNX1 mutations contribute to the pathobiology of secondary MDS/AML is still unknown. This mini-review focusses on the role of RUNX1 mutations as the most common secondary leukemogenic hit in MDS/AML evolving from severe congenital neutropenia (SCN).

  • Background: Posaconazole is a broad-spectrum triazole antifungal agent and the most recommended prophylactic antifungal agent for patients with acute myeloid leukemia (AML) undergoing induction chemotherapy. In this study, we evaluated the status and effectiveness of posaconazole as a prophylactic antifungal agent in pediatric patients receiving induction chemotherapy for AML. Methods: We retrospectively reviewed the electronic medical records of 36 pediatric patients with AML (between January 2013 and September 2017) at the Yonsei University Health System. Invasive fungal disease (IFD) was assessed as the primary endpoint of prophylactic antifungal effect. The secondary endpoints were incidence of fever, persistent fever despite the use of broad-spectrum antibiotics for 72 h, alteration of antifungal agent, intensive care unit admission, and death within 100 days. Results: Among the 36 patients, 18 patients used posaconazole, 12 were treated with suspension formula, and 6 of them were treated with tablets. Eighteen patients did not use antifungal agents prophylactically. The mean number of days of posaconazole administration was $26.8{\pm}16days$. IFD occurred in 2/18 (11.1%) patients in the no prophylaxis group and in 1/18 (5.6%) patients in the posaconazole group (p=0.49). Conclusion: Posaconazole is expected to be useful for the prevention of IFD in pediatric patients with AML undergoing induction chemotherapy. Prospective studies of the effectiveness of posaconazole prophylaxis should be conducted in more pediatric patients in the future.

  • Objective This study aimed to report an improvement of influenza virus infection managed with Sasang Constitutional Medicine in a Soeumin patient with thrombocytopenia and histories of acute myeloid leukemia and interstitial pulmonary disease. Methods The medical records of patient including vital signs, laboratory test, simple x-ray, and symptoms were reviewed retrospectively. Patient was treated with Gunggwihyangso-san gamibang without any antiviral agents under the diagnosis of Congestive Hyperpsychotic symptomatology of Kidney Heat-based Exterior Heat disease. Results At admission, symptoms of shivering, fever, cough and myalgia were presented and her skin temperature was over $39^{\circ}C$. Influenza A virus was detected and inflammation biomarkers were elevated. After administration of herb medication, her vital signs and symptoms were improved and elevated inflammation biomarkers were decreased. There was no secondary complication during the treatment period. Conclusions This case treated with Gunggwihyangso-san gamibang showed a significant improvement from viral infection without any complication.

  • 본 증례에서는 한방치료를 받은 두 명의 골수이형성증후군 환자를 통하여 골수이형성증후군에 대한 한방치료의 효과를 보여주고자 하였다. 골수이형성증후군은 골수의 증식과 구성 세포들의 이형성, 비효율적인 조혈을 특징으로 하는 골수의 악성 종양이다. 현재까지 골수이형성증후군에 대한 완벽한 치료법은 없으며 골수이형성증후군의 증상을 경감시키거나 급성 골수성 백혈병으로의 진행을 막는 목적으로 치료가 이뤄지고 있다. 첫 번째 환자는 1차성 골수이형성증후군 환자로 2011년 1월부터 2016년 현재까지 꾸준히 침 치료 및 한약치료를 받고 있다. 두 번째 환자는 난소암 치료를 위한 항암화학요법의 부작용으로 생긴 2차성 골수이형성증후군 환자로 2010년 10월부터 4년간 꾸준한 한약 복용 및 3번의 입원치료를 받은 환자이다. 침 치료, 한약 치료와 함께 환자들의 상태를 평가하기 위해 정기적인 혈액검사가 이루어졌다. 골수이형성증후군 진단 후 두 달에 한 번씩 수혈을 받으며 수혈 의존 경향을 보이던 첫 번째 환자는 한방치료 후 단 두 번의 수혈밖에 받지 않았고 급성골수성백혈병으로 진행하지도 않았으며 건강한 몸 상태를 유지하고 있다. 두 번째 환자 역시 꾸준한 한방치료를 통해 비교적 좋은 삶의 질을 유지하며 기본 체력 또한 많이 상승되면서 골수 이식을 받을 정도까지 몸 상태가 개선되었다. 본 증례보고는 마땅한 치료법이 없는 골수이형성증후군 환자들에게 한방 치료가 특별한 부작용 없이 환자들이 호소하는 증상을 개선하고 기본적인 체력 증진에 도움이 되며 급성 골수성 백혈병으로의 진행을 예방하는 동시에 기존의 보존적 치료법의 효과를 극대화 시키는 효과가 있음을 보여주는 증례라고 하겠다.

  • Background: Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders characterized by proliferation of one or more myeloid lineages. Polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF) are classical Philadelphia chromosome (Ph)-negative MPN that have a Janus Kinase 2 (JAK2) mutation, especially JAK2V617F in the majority of patients. The major complications of Ph-negative MPNs are thrombosis, hemorrhage, and leukemic transformation. Objective: To study clinical manifestations including symptoms, signs, laboratory findings, and JAK2V617F mutations of Ph-negative MPN (PV, ET and PMF) as well as their complications. Materials and Methods: All Ph-negative MPN (PV, ET and PMF) patients who attended the Hematology Clinic at Maharaj Nakorn Chiang Mai Hospital from January, 1 2003 through December, 31 2013 were retrospectively reviewed for demographic data, clinical characteristics, complete blood count, JAK2V617F mutation analysis, treatment, and complications. Results: One hundred and fifty seven patients were included in the study. They were classified as PV, ET and PMF for 68, 83 and 6 with median ages of 60, 61, and 68 years, respectively. JAK2V617F mutations were detected in 88%, 69%, and 100% of PV, ET and PMF patients. PV had the highest incidence of thrombosis (PV 29%, ET 14%, and PMF 0%) that occurred in both arterial and venous sites whereas PMF had the highest incidence of bleeding (PMF 17%, ET 11%, and PV 7%). During follow up, there was one ET patient that transformed to acute leukemia and five cases that developed thrombosis (three ET and two PV patients). No secondary myelofibrosis and death cases were encountered. Conclusions: Ph-negative MPNs have various clinical manifestations. JAK2V617F mutations are present in the majority of PV, ET, and PMF patients. This study confirmed that thrombosis and bleeding are the most significant complications in patients with Ph-negative MPN.
