Background. β-Thalassemia is a common inherited hemolytic disorder in Palestine. Red blood cell (RBC) transfusion is the principal treatment but it may cause RBC alloimmunization. This study was conducted to determine the prevalence and characteristics of RBC alloimmunization among thalassemic patients in northern governorates of Palestine. Methods. A prospective multicenter observational study was conducted in the thalassemia transfusion centers in the northern governorates of Palestine. The study included 215 thalassemia patients who received regular blood transfusions. Clinical and transfusion records of patients were examined. Antibody screening and identification was conducted using the microcolum gel technique. Results. Two hundred fifteen patients were included in the study. More than half (52.1%) of the patients were males. The median age of patients was 18 years (range: 12–24 years). The most frequent blood group was A (40.5%). Alloantibodies were detected in 12.6% of patients. Anti-D (33.3%), anti-K (25.9%) and anti-E (14.8%) were the most commonly isolated antibodies. There was no association between age, sex, starting age of transfusion, number of transfused units, history of splenectomy and alloimmunization. Conclusions. Anti-Rh and anti-K antibodies were common among this cohort of patients. Age, sex, starting age of transfusion, number of transfused units, and history of splenectomy could not predict the occurrence of alloimmunization.

Sheehan’s syndrome is a postpartum hypopituitarism state caused by necrosis of the pituitary gland. It is usually the result of severe hypotension or shock caused by massive hemorrhage during or after delivery. Sheehan’s syndrome symptoms are often subtle and hence it is diagnosed late. Herein, we report a case of a 41-year-old woman who developed severe postpartum hemorrhage after childbirth that required a total abdominal hysterectomy to control bleeding at the age of 36 years. Since then, she has progressively developed symptoms of headache, general fatigue, and malaise, and finally presented with pancytopenia for investigations. Anemia is a well-known hematological association with Sheehan’s syndrome while pancytopenia is rarely reported. However, complete recovery of pancytopenia was observed after the treatment. Pancytopenia (due to bone marrow failure to produce cells) is a serious finding in clinical practice that causes significant stress as it may point to a diagnosis of malignancy (mainly leukemia) and other serious disorders. Despite being a rare cause, a high index of suspicion is required from the physicians in women with pancytopenia, in order to look for a possible treatable cause of pancytopenia (like Sheehan's syndrome), if the common causes were excluded.
