目的 通过血清学和基因分型对1例自身免疫性溶血性贫血(AIHA)患者类抗-D抗体进行特异性鉴定,指导临床安全用血。方法 选择同济大学附属同济医院收治的1例女性AIHA患者为研究对象。采用PCR-SSP法检测鉴定患者ABO、Rh血型,患者血清标本进行吸收放散试验,利用谱细胞对患者血清及放散液中的不规则抗体进行特异性鉴定。回顾性分析患者的病例资料,总结其抗体处理结果和临床诊治经过。结果 患者血型为B型DCCee,不规则抗体筛查、直接抗人球蛋白试验结果均阳性,血清及放散液中均检出特异性类抗-D抗体,给予患者相容性去白细胞悬浮红细胞4 U输血后,血红蛋白(Hb)升高至56 g/L,未出现输血反应。采用糖皮质激素治疗后,患者Hb上升至62 g/L,贫血症状缓解。结论 血清学检测联合基因分型可鉴定具有同种抗体特异性的自身抗体,类抗-D抗体AIHA患者治疗首选糖皮质激素,危急情况下需要输血治疗时,应选择类抗体相应抗原阴性的红细胞,输血效果较好。  相似文献

Summary 56 patients with autoimmune hemolytic anemia (warm type) (AIHA) were investigated for immunoglobulin deviations. Of these, 43 were repeatedly analyzed (mean 4 times). The mean observation time was 20 months. The immunoglobulin values were correlated with clinical (degree of hemolysis) and serological (immunoglobulin class of autoantibodies; strength of antiglobulin reaction) parameters and statistically evaluated by variance analysis. Although no significant deviations of immunoglobulins in AIHA were found as compared to a normal control group, the immuno-globulin disturbance most frequently seen was an elevation of IgM. This is inter-preted as a possible lack or functional impairment of immunoregulatory T cells in AIHA.Supported by the Deutsche Forschungsgemeinschaft (Mu 277/6).  相似文献

This report describes a case of congenital dyserythropoietic anemia (CDA) type I diagnosed in a 22-year-old woman with a two year history of macrocytic anemia. Light microscopy study of bone marrow disclosed only minor and nonspecific findings, without erythroid hyperplasia. Electron microscopy of bone marrow erythroblasts surprisingly showed most of the classical features of CDA type I. Electron microscopy may be an important tool for the diagnosis of macrocytic anemia of obscure origin, especially in young patients.  相似文献

Pernicious anemia appears to be autoimmune in origin and is associated with immune disorders of several organ systems. We report 4 patients with pernicious anemia and immune cytopenias, an association that may sometimes pose diagnostic problems unless specifically considered. Pernicious anemia coexisted with or was closely followed by idiopathic thrombocytopenic purpura in 3 patients and by autoimmune hemolytic anemia in a 4th patient. In addition to cobalamin therapy, all patients required corticosteroids (2 also received danazol), while 1 also required splenectomy. All 4 patients were women. The 3 patients with idiopathic thrombocytopenic purpura were also blood group O and were iron-deficient. Autoimmune cytopenias may occur in patients with treated or untreated pernicious anemia and require specific therapy.  相似文献

Background and aims  Mutations in DNA mismatch repair genes are associated with high risk of digestive malignancies [hereditary non-polyposis colorectal cancer (HNPCC); Lynch syndrome]; mutations of APC and MYH are associated with classic and attenuated familial adenomatous polyposis (FAP). Although the early onset of tumors in both syndromes is characteristic of their genetic origin, pediatric malignancies remain rare. Certain reports have found familial colorectal cancer (CRC) occurring in very young patients associated with mutations in more than one gene. Materials and method  A family corresponding to the Amsterdam criteria for HNPCC, including two cases of colorectal cancer before the age of 25 years, was analyzed for mutations in the MSH2 genes by sequencing. Because polyposis was observed in a patient who developed CRC at age 16, the APC gene was also sequenced. Results  A truncating mutation in the MSH2 gene, c.258_259delTG, was carried by patients developing cancer of the colon (two patients), uterus, kidney, bladder, and/or small intestine at ages 16, 24, 43, 44, 45, and 57, respectively. A patient with CRC at age 16 was found to carry the APC c.3183_3187del5 mutation as well as the MSH2 mutation, and it is inferred that her father, deceased of CRC at age 24, was also a double heterozygote. Interpretation  These results confirm that vigilance is required when interpreting molecular results for families with very young patients, as more than one gene may contribute to the genetic risk. Cancer screening measures must also be adapted to the earlier and more penetrant risk to double heterozygotes.  相似文献

 Hepatosplenic gamma/delta T-cell lymphoma is recognized as a subset of peripheral T-cell lymphoma in the REAL classification. Histologically these tumors are characterized by a mixture of small to medium-sized atypical lymphocytes. To date, approximately 15 cases of hepatosplenic γδ T-cell lymphoma have been reported. Affected individuals are usually young adults with a median age of 34 years. Patients commonly present with B symptoms and hepatosplenomegaly, but an absence of lymphadenopathy. The disease follows an aggressive course with median survival of 12–14 months and poor response to combination chemotherapy agents. Occasionally, the occurrence of frank blast transformation constitutes a terminal event for the patient. Although cytopenias are relatively common, nonimmune hemolytic anemia has been reported in one patient only. This is the first report of autoimmune hemolytic anemia associated with hepatosplenic γδ T-cell lymphoma. Received: 16 October 1996 / Accepted: 5 December 1996  相似文献
