Abstract

Objective: To explore the clinical characteristics, treatment and prognosis in 17 patients with primary cold agglutinin disease (CAD) . Methods: Clinical data, treatment and survival status of 17 patients diagnosed with primary cold agglutinin disease in Peking Union Medical College Hospital during April 2007 to October 2016 were retrospectively analyzed. The MYD88(L265P) mutation was tested in 4 patients. Results: The median age of 17 patients was 67 years (range, 51-86 years) , and male- to female ratio was 1.1∶1. Seven patients were diagnosed with indolent lymphoma, including 3 Waldenstrom macroglobulinemia/lymphoplasmacytic lymphoma (WM/LPL) , 2 small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) , and 2 splenic marginal zone lymphoma (SMZL) . 15 patients experienced anemia. The median HGB level was 67 (35-127) g/L. 11 patients had cold agglutinin (CA) titers ≥1∶64, with median CA of 1∶1 024. MYD88(L265P) mutation was detected in 1 patient. 12 patients received drug therapy: 7 were treated with glucocorticoid-based therapy and 1 patient responded to treatment; 5 received rituximab-based therapy and 3 patients responded to treatment. With a median follow-up of 14 (0.5-96) months, the median overall survival was...Continue Reading

Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in the circulation. Discover the latest research on AIHA here.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
