  • Anemia is a common problem in sick dogs, and immune-mediated hemolytic anemia (IMHA) is one of the most common causes of anemia in dogs. Since death can occur rapidly in dogs with IMHA even with appropriate treatment, it is important to differentiate IMHA from other causes of anemia in its first stages. To diagnose underlying diseases in anemic dogs and differentiate IMHA cases from others, 29 patient dogs suffering from severe anemia that had been referred to Veterinary Medical Teaching Hospital at a National University from June 2004 to April 2005 were examined. The most common cause of anemia in the patient dogs was found to be liver disease accounting for 31.0% (9/29) of all, and the second most common was IMHA with 13.7% (4/29). Four dogs confirmed as IMHA cases all reacted positive to direct anti-globulin test and showed spherocytes and polychromatic erythrocytes in the blood smear. Most of the IMHA cases (3/4) were female aged 2 to 7 years and were in a severe state of anemia with less than 20% of PCV.

  • A patient with intravascular hemolysis due to residual shunt and right ventricular outflow track obstruction after total correction of TOF was presented. The patient was 29 years old female. She underwented VSD closure with dacron patch, infundibulectomy, pulmonic valvotomy and direct closure of PFO. 8 months after the operation, severe intravascular hemolysis and hemolytic anemia appeared. Conservative therapies were not effective, her general condition and laboratory finding got worse gradually. She underwent reoperation, the shunt was closed and right ventricular outflow tract obstruction was corrected by pulmonary valvotomy, infudibulectomy and transannular patch. After operation, hemolysis disappeared dramatically. Severe hemolysis may induce renal failure and necessitate transfusion frequently. If hemolytic anemia is not corrected by conservative treatment, early reoperation is required.

  • It has been known that garlic, one of the essential ingredient in korean food, has a hypotensive effect. and it is reported that they lower the level of triglycerides, cholesterol and glucose in blood. Especially, the sulfur containing amine acid and the derivatives of the garlic has the counteracting effect to heavy metals. Nowadays, the garlic is known for its efficiency for the various kinds of cancer, neoplasms, hypertension, arteriosclerosis and apoplexy. But, it is reported that the intake of the excessive amount of garlic causes hemolytic anemia recently. The hemolytic anemia is more severe especially in HK phenotype dogs which has a Na-K-ATPase activity. Therefore, this study was performed to examine the effect on the blood of the HK phenotype Jindo dogs when administered the excessive amount of garlic. HK phenotype group showed the significant decrease on RBC, WBC, PCV, Hb, MCV, MCHC, GSH, Met-Hb but LK phenotype group didn't show the significant decrease.

  • Immune checkpoint inhibitors (ICIs) have become the main drugs for programmed cell death receptor-1 or ligand-1 expressing non-small cell lung cancer (NSCLC) combined with conventional chemotherapy. ICIs are generally more tolerable than cytotoxic chemotherapies in terms of toxicity, and ICI-related adverse events are mild and manageable. However, these drugs may lead to unexpected severe adverse events such as immune-related hematologic toxicities, which could be life-threatening. Here, a rare case of a pembrolizumab-related adverse event in a patient with NSCLC who showed early-onset hemolytic anemia and recovered by high-dose steroid and a series of plasma exchanges is reported.

  • A 10-year-old spayed female Maltese presented with purpura and hematemesis. Initial laboratory evaluation revealed immune-mediated thrombocytopenia, but evidence of hemolytic anemia was not identified. Three milligrams of human intravenous immunoglobulin (hIVIG) was administered for 3 hours following prednisolone and mycophenolate mofetil. A pale mucous membrane was identified, and the packed cell volume decreased by 3%. Blood film examination revealed significant spherocytosis with auto-agglutination. Blood transfusions and immunosuppression were continued for 4 days, and hIVIG was discontinued. This report describes a case of increased immune-mediated hemolysis after hIVIG administration, possibly due to new-onset immune-mediated hemolytic anemia or enhanced immunogenicity.

  • Three different dogs who had immune-mediated hemolytic anemia (IMHA) were treated for more than two weeks with blood transfusion in an animal clinic. Despite this treatment and hospitalization, there was no clinical improvement in clinical signs as well as complete blood cell count (CBC) including hematocrit (HCT) and C-reactive protein (CRP). All cases were then injected two or three times with allogeneic stem cells through an intravenous route for treatment. Upon administrating stem cells to the IMHA dogs, clinical conditions and the indexes of HCT and CRP were clinically improved within or close to normal ranges.

  • 목 적 : 용혈성 빈혈은 진단방법의 발전과 관심의 증대로 해마다 빈도가 증가하고 있다. 저자들은 지난 15년간 용혈성 빈혈로 진단받은 환자들을 토대로 원인에 따라 적혈구 내적 요인과 외적 요인으로 나누어 임상적 양상을 후향적으로 조사하여 차이를 분석하였다. 방 법 : 1987년 1월에서 2002년 5월까지 연세대학교 의과대학 세브란스병원 소아과에 내원하여 용혈성 빈혈을 진단 받은 58명의 환자들을 대상으로 진단 당시 연령, 성별, 증상, 혈색소, 망상구 수, 백혈구 수, 혈소판 수, 총 빌리루빈과 간접 빌리루빈, 비장비대 여부, Coombs' 반응, Alanine aminotransferase/Aspartate aminotransferase, 혈액요소질소 및 크레아티닌 치, 소변 검사, 치료 방법, 재원일수, 수혈 횟수를 분석하였다. 결 과 : 전체 환자 58명 중 적혈구 내적 결함에 의한 용혈성 빈혈(group I)이 21례(36%)로 유전성 구상적혈구증 19례, glucose-6-PD 결핍증 2례가 있었고, 적혈구 외적 결함에 의한 용혈성 빈혈(group II)은 34례(59%)로 용혈성요독증후군 9례, 온항체에 의한 자가면역 7례, 한랭 항체에 의한 자가면역 6례, 약물에 의한 경우 4례, 신생아 용혈성 질환 3례, 기계적 손상에 의한 경우 2례, 전신성 홍반성 낭창 2례, 악성종양 1례였다. 미분류는 3례(5%)였다. 성별 분포는 남자 : 여자의 비율이 group I은 2.5 : 1(15명 : 6명), group II는 1 : 1.5(15명 : 22명)이었다. 두 군간의 임상 양상을 비교 분석하였을 때 통계적으로 의미 있게(P<0.05) 차이를 보인 항목으로는 진단 시 혈색소 치, 혈액요소 질소 및 크레아티닌 치, 비장비대 여부로 나타났다. 치료에 있어서 내적 요인에서는 비장절제술만 시행한 경우가 대부분이었으며 외적 요인에서는 스테로이드, 복막투석, 면역글로불린 등 다양한 치료가 시행되었다. 결 론 : 소아 용혈성 빈혈 환자에서 원인에 따른 임상 양상을 비교 분석하여 본 결과, 외적 요인으로 인한 경우 진단 당시 혈색소 치가 더 낮고, 혈액요소질소 및 크레아티닌 치가 더 높은 것이 의미 있게 관찰되었으며, 내적 요인으로 인한 경우 비장비대가 의미 있게 더 많은 것으로 나타났다.

  • A 3-year-old spayed female Persian feline with non regenerative anemia showed persistent autoagglutination in EDTA anticoagulated blood. Primary immune-mediated hemolytic anemia (IMHA) was suspected and the underlying causes for IMHA were excluded by radiologic, sonographic, serologic and molecular studies. Cytologic examination of the bone marrow revealed that dysmyelopoiesis and dysplastic changes were prominent in the erythroid cells. These changes included asynchronous maturation of the nucleus and cytoplasm, binucleation, trinucleation, fragmented or lobulated nuclei and multilineages. Mild dysgranulopoiesis and dysmegakaryocytopoiesis were also detected including pseudo Pelger-Huet anomalies, giant band neutrophils, asynchronous maturation of the nucleus and cytoplasm in granulopoiesis and large hypolobulated forms as well as dwarf megakaryocytes in megakaryocytopoiesis. Myelodysplastic syndrome and congenital dysmyelopoiesis was ruled out by the low number of blast cells. Finally, secondary dysmyelopoiesis associated with IMHA was diagnosed and immunosuppressive treatment was successfully responsive.

  • Immune-mediated hemolytic anemia (IMHA) is autoimmune disease which is anemia caused by own immune system destroying the red blood cells (RBC). It can be diagnosed with spherocytosis, positive auto-agglutination of RBCs and direct antiglobulin test (DAT, Coomb's test). The treatment for IMHA are blood transfusion, immunosuppressive agents including glucocorticoids and other supportive therapies. Danazol is synthetic androgen that has effect of interfering the autoimmune reaction to RBCs. It can be used as an adjunctive agent in addition to glucocorticoids. To investigate its effectiveness, the medical records of 10 IMHA-diagnosed dogs were evaluated. All subjects were treated with blood transfusion, prednisolone, mycophenolate mofetil, and intravenous human immunoglobulin G. Additionally, 6 subjects were administered with danazol and 4 subjects were not. The results of initial blood examination and responses to the treatment for IMHA were compared between the groups. There were significant differences in the number of blood transfusions; once in group with danazol, twice in group without danazol, duration of recovery to normal hematocrit; 7.67±3.08 days in group with danazol, 22.00±5.66 days in group without danazol, and hospitalization; 5.17±0.75 days in group with danazol, 12.75±2.22 days in group without danazol. Therefore, danazol has potential effective on treating IMHA for rapid improvement.
