DISCUSSION Anemia is a major cause of mortality and morbidity in developing countries. In these situations resources to determine the underlying etiology remain poor. Blood loss (hemorrhage); decreased production of red cells; increased destruction of red cells (hemolysis) are three basic mechanisms for developing anemia. Pregnancy is one of the causes of bone marrow suppression and it is likely to be immune mediated since the pregnancy is a state of hypoimmunity. Hematopoeisis is likely to be suppressed by cytotoxic T lymphocytes (CTLs). In patients with a plastic anemia CD4 and HLA-DR+ are detectable in both blood and bone marrow. These cells produce inhibitory cytokines like tumor necrosis factor and gamma interferon which affect the mitotic cells and induce nitric oxide synthase and nitric oxide production by marrow cells which related to immune mediated cytotoxicity and the elimination of hematopoeitic cells. Steroid and other immunosuppressant might play a role in the improvement however in our case prednisilone was introduced too late. Termination of pregnancy might resolve the problem if the patient presented earlier. Pregnancy associated a plastic anemia is a cause of woman death which could be due to bleeding, infection or complications of anemia and in our patient pulmonary hemorrhage is likely to be responsible of this death supported by shortness of breathing and sputum stained blood
