Adult Primary Myelodysplastic Syndrome: Experience from a Tertiary Care Center in Pakistan


Department of Hematology and Blood Bank, Liaquat National Hospital and Medical College, Karachi, Pakistan


Background: Primary myelodysplastic syndrome (MDS) is an acquired clonal disorder of myeloid progenitor cells, characterized by peripheral cytopenias in the presence of hypercellular marrow with dysplastic features. Our aim was to study the demographical and clinicopathological features of adult Pakistani patients with MDS at disease presentation. Materials and Methods: This single centre study was conducted at Liaquat National Hospital and Medical College, extending from January 2010 to December 2014. Data were retrieved from the patient archives. Results: Overall 45 patients were diagnosed at our institution with de novo MDS during the study period. There were 28 males and 17 females. Age ranged between 18 and 95 years with a mean age of 57.617.4 years and median of 64 years. The male to female ratio was 1.7:1. The main presenting complaints were generalized fatigue (60%), fever (33.3%), dyspnea (15.5%), bleeding (13.3%) and weight loss (11.1%). Examination was unremarkable in 42.2% of patients. Physical examination revealed pallor in 37.7%, followed by petechial and purpuric rashes in 20%. The commonest laboratory finding was anemia (hemoglobin in 41 (91.1%) patients. Out of these, 27 (60%) patients had normocytic anemia, followed by macrocytic (22.2%) and microcytic (8.8%). Conclusions: Primary MDS in Pakistani patients demonstrates a male preponderance. The proportion of anemic patients was high in our series with predominance of normocytic anemia. However, other clinico-hematological features appear comparable to published data.
