A 34-year-old lady presenting with features of cold agglutinin disease during the course of systemic lupus erythematosus is described. Cold antibody titer was very high (1 in 4096) with specificity for 'I' antigen. Even though she had poor prognostic factors like high titer of cold antibodies with low thermal amplitude, she responded well to prednisolone.

The irregular antibodies are other than antibodies from ABO blood group system because of pregnancies and blood transfusions, clinical autoimmune, drug-induced etc. The irregular IgG and/or IgM antibodies emerge and lead to the difficult identification of clinical blood type, difficult matching of blood, hemolytic disease of newborn, hemolytic transfusion reaction, and so on. It is very necessary to screen and identify the irregular antibodies before blood transfusion or antepartum. For some difficult identifying samples, some detections on serological level should be done firstly, combining with flow cytometry analysis, the difficult-matching patients' genotypes and fetal genotypes were detected by molecular biology techniques such as PCR and PCR-SSP in order to further predict fetal hemolytic disease of newborn and to provide the right blood to difficult-matching patients, and free fetal DNA extracted from maternal plasma. So that some measures must early be taken for clinical prevention and treatment to reduce immune hemolytic reactions. In this paper, the emergence of irregular antibodies, species, laboratory testing, pathogenesis, clinical symptoms and the current research are reviewed.

OBJECTIVETo analyze the diagnosis and treatment of autoimmune hemolytic anemia (AIHA) in liver transplant recipients.

METHODSA retrospective analysis was conducted of 3 patients who developed AIHA following orthotopic liver transplantation. The results of hemolysis tests and examinations of hemoglobin, white blood cells, platelets, total bilirubin, and alanine aminotransferase before and after treatments were reviewed.

RESULTSThese 3 patients developed AIHA following the transplantation possibly in association with the use of immunosuppressive agents, and the condition was effectively controlled after corresponding treatments.

CONCLUSIONAIHA is a uncommon complication after liver transplantation and can be cured after a definitive diagnosis with corresponding treatments.

Autoimmunity is thought to play a central role in the pathogenesis of inflammatory bowel disease and associated extraintestinal manifestations. Autoimmune hemolytic anemia associated with ulcerative colitis is a rare occurrence. No more than 50 cases have been described in the international literatures, and only 2 cases reported in Korea. A 29-year-old woman who was diagnosed as ulcerative colitis two years ago was complicated with autoimmune hemolytic anemia, and did not respond to steroid therapy. Ultimately, total colectomy and splenectomy were carried out for the treatment of ulcerative colitis and hemolytic anemia. After the operation, anemia was resolved. We present the case with a review of literature.

Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovarian teratoma. A 25-yr-old woman complained of general weakness and dizziness for 1 week. The hemoglobin level was 4.2 g/dL, and the direct and indirect antiglobulin tests were all positive. The abdominal computed tomography scan revealed a huge left ovarian mass, and this indicated a teratoma. She was refractory to corticosteroid therapy; however, after surgical resection of the ovarian mass, the hemoglobin level and the reticulocyte count were gradually normalized. The mass was well encapsulated and contained hair and teeth. She was diagnosed as having autoimmune hemolytic anemia associated with an ovarian teratoma. To the best of our knowledge, this is the first such a case to be reported in Korea.

The cases of lymphoma accompanied or preceded by Coombs' test positive autoimmune hemolytic anemia (AIHA) have been reported. However, Coombs' test negative AIHA prior to the diagnosis of lymphoma was rarely described. Herein, this article reports a case of non-Hodgkin's lymphoma (NHL) preceded about 1.5 years by Coombs test negative AIHA. A woman aged 69 was diagnosed with HA based on the history and laboratory tests. Further studies revealed that this patient was negative with Coombs' test for IgG, IgM, IgA and C3. After all possible causes of HA, especially malignancies were ruled out, the patient was diagnosed with Coombs' test negative AIHA and treated with prednisolone. The patient responded well initially to steroid treatment. Two recurrences of acute HA were presented at time of 10 months post steroid cessation, and immediately after an attempt to withdraw steroid, respectively, but the hemolysis was effectively controlled by reinstitution of prednisolone. At third recurrence, however, the patient was no longer responding to steroid, and was found with cervical lymphadenopathy. Coombs' test for IgG, IgM, IgA and C3 remained negative. B cell NHL was diagnosed by pathology. After receiving 6 cycles of CHOP chemotherapy, the patient was lymphoma free, but the hemolysis was not improved, however, which was effectively controlled by the following low dose-rituximab (RTX) therapy. The patient was still kept in a remission of lymphoma free of anemia. In conclusion, this report presented a very rare case of NHL with Coombs' test negative AIHA as initial major clinical manifestation.

OBJECTIVETo analyse the relapse rate and risk factors of autoimmune hemolytic anemia (AIHA) and Evans syndrome.

METHODSFifty two cases of AIHA and Evans syndrome in remission being followed up for 1 - 14 years (median time 3.8 years) were analysed for relapse rate. The risk factors of relapse were analysed by case-control study.

RESULTSThe total relapse rate of these AIHA and Evans syndrome patients was 57.7%, and the median remission duration to the first relapse was 9 months. The relapse rates in patients with negative Coombs test, warm autoantibodies and both of warm and cold autoantibodies were 30.8% (4/13), 54.0% (13/24) and 86.7% (13/15), respectively. The relapse rate in patients with cold antibody was the highest (P < 0.05). The relapse rate in patients with antibody titer >or= 100 was 92.9% (13/14) and was higher than that in patients with antibody titer < 100 [59.5% (13/22)] (P < 0.05). Patients treated with prednisone and cyclosporin relapsed less than those treated with prednisone alone, and the relapse was related to the therapy course of prednisone and CsA.

CONCLUSIONBecause of the high relapse rate, AIHA and Evans syndrome should be treated according to the class of autoantibodies, and with longer course of prednisone and cyclosporin and prophylaxis of infection.
