Clinico-hematological study of pancytopenia: A single-center experience from north Himalayan region of India

Background: Pancytopenia, an important hematological presentation is associated with different causes, which may vary in different regions. Uttarakhand, a north Himalayan state of India lacks studies of pancytopenia and the prevalent causes present in this region. Therefore, the present study was conducted to study the clinico-hematological profile of pancytopenia in a tertiary care center in the Uttarakhand, a north Himalayan state of India. It was also intended to study if these causes showed any variation from other studies done in different regions of India. Materials and Methods: The present observational study was conducted in a tertiary care institute situated in Uttarakhand state of India over a period of 1 year and 8 month from June 2017 to Feb 2019 including all the cases of pancytopenia. Results: The most common cause of pancytopenia was megaloblastic anemia (25%), followed by aleukemic leukemia and hypoplastic/aplastic anemia (19.1% each). Visceral leishmaniasis also constituted an important cause of pancytopenia in this study (11.7%). Conclusion: The study concludes that megaloblastic anemia and aleukemic leukemia are the most common cause of pancytopenia. Although leishmaniasis is considered to be non-endemic in this region, it constitutes an important cause of pancytopenia here. The clinicians, especially the physicians practicing the primary care and pathologists, should be aware of the different causes of pancytopenia present in this Himalayan region of India; therefore, delay in diagnosis can be prevented along with unnecessary investigations.
