Cold agglutinin disease is a kind of autoimmune hemolytic anemia, caused by cold agglutinin, serum autoantibodies activated at reduced body temperatures to produce red blood cell agglutination and hemolysis. In this paper we described a case of severe hemolytic anemia in a cold agglutinin disease patient treated with therapeutic plasma exchange. Therapeutic plasma exchanges were performed four times every other day. Over the same period, a total of 8 units of washed red blood cells were transfused. Then hemoglobin was increased from 4.0 g/dL to 7.8 g/dL. On the 12th hospital day hemoglobin level was decreased again to 4.2 g/dL and fludarabine chemotherapy was started on the 14th hospital day. The patient's symptoms were relieved and she was discharged on the 30th hospital day. As in this case, therapeutic plasma exchange could be considered as secondary therapy for temporary improvement of acute severe hemolytic anemia in cold agglutinin disease.

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 purpose of this study was to review the clinical hematological, immunological features and treatment responsiveness in children with autoimmune hemolytic anemia (AHA). Eight children with AHA and positive Coombs' test was evaluated. Seven patients presented with acute onset of symptoms and histories of infection. One case was diagnosed as Evans syndrome, one as a chromosomal anomaly, and one case was combined with the Guillain-Barre syndrome. Among 8 the patients, 4 exhibited warm antibodies and the remainder had cold antibodies. The patients were given washed packed red blood cells, prednisolone or immunosuppressive drugs (6-MP or cyclophosphamide). Five patients responded well to transfusion and/or prednisolone, one patient died and one patient showed no response in 5 months of follow up.

Thrombotic microangiopathy (TMA) is a group of highly heterogeneous, acute and severe clinicopathological syndromes, characterized by microangiopathic hemolytic anemia (MAHA), thrombocytopenia and ischemic injury of end organs. TMA has the characteristics of dangerous condition, multiple organ involvement and high mortality. Patients with severe TMA need to be admitted to intensive care unit (ICU) for organ function support therapy. Early and rapid evaluation, differential diagnosis, and timely and effective treatment are the key to improve the prognosis of TMA patients. Here, we review the pathophysiological changes, diagnosis differential diagnosis, and treatment of the severe TMA in adult.

In order to screen the compatible red cells by using extracorporal hemolysis test for acute autoimmune hemolytic anemia (AIHA) patients who were difficult to be matched by automatic microcolumn gel indirect antiglobulin test. Twenty-six cases of AIHA were chosen as control group, to whom the same type of donor red blood cells were infused with the weakest blood agglutination; 12 cases of acute AIHA patients were chosen as test group, these patients were difficult to be matched by automatic microcolumn gel indirect antiglobulin test, and the donor red cells without hemolysis by extracoral hemolysis test were transfused for them. The results showed that compared with the control group,the effect of transfusion was better in test group (P < 0.01), with 2.26 U leukocyte-depleted erythrocyte suspension in average, whose hemoglobin, reticulocyte and total bilirubin levels were changed significantly compared with those before blood transfusion (P < 0.01) . It is concluded that the compatible red blood cells for the acute AIHA patients can be screened by the extracorporal hemolysis test, when it is difficult to screen by the automatic microcolumn gel indirect antiglobulin test.
