We studied the effects of peripheral blood lymphocytes from 16 untransfused patients with severe aplastic anemia (AA) of diverse etiologies on the growth of granulocyte-macrophage colonies from normal marrows. Normal lymphocytes in our system increased the number of granulocytic colonies by 31 +/- 6% (mean +/- SEM). Lymphocytes from 3 of 16 untransfused AA patients significantly inhibited growt...

We analyzed the effect of antithymocyte globulin (ATG) with or without androgens in 121 patients with aplastic anemia. Fifty-three patients with moderate to severe aplastic anemia were prospectively randomized to receive ATG with or without oral androgens. Eleven of 26 patients (42%) receiving ATG plus androgen responded, including three complete and eight partial responses. Twelve of 27 patien...

A 10-year-old boy was admitted with complaints of fever, pallor, fatigue and skin bleeds of 10 days duration and diagnosed as very severe aplastic anemia. He was given intensive immunosuppressive therapy but showed no response to therapy. He later evolved into acute myeloid leukemia. The occurrence of AML is reviewed and possible pathogenesis is discussed.

Background: Aplastic anemia although a rare hematological disorder but it is associated with poor prognosis and high mortality. It matter of greater public health concern for the Asian population prevalence 3 times than other part globe. Exposures specific drugs, chemicals others have been connected an AA etiology. We aimed to examine association antimicrobial drugs exposures AA.
