Clinical and hematological evaluation of geriatric anemia

Anemia in the elderly is a cause of concern. It is not merely physiological due to aging and requires appropriate evaluation. Anemia has a significant negative impact on cardiac function, cognition, sleep, frequent hospitalization, mobility, morbidity, and mortality. Anemia in the elderly is attributable to many causes: nutrient deficiencies, chronic inflammatory diseases, thyroid disorders, diabetes mellitus, gastrointestinal (GI) tumors and bleeding, chemotherapy-induced anemia, and drug-induced hemolysis.

We aimed to evaluate the clinical and hematological profile of anemia in 100 patients aged above 60 years.

We performed a cross-sectional type of study in a tertiary care center including male and female patients aged 60 years and above and whose hemoglobin was less than 13 g/dl and less than 12 g/dl, respectively. Clinical history, complete blood picture, and peripheral smear were obtained in all patients. Serum iron profile was done in patients with micro-normocytic anemia. Vitamin B12 and folate assays were done in patients with normo-macrocytic anemia and those with pancytopenia. Bone marrow studies and endoscopies were done in cases wherever deemed appropriate.

The majority of the patients had either severe or moderate anemia. 49% of the patients had normocytic anemia. The commonest cause for anemia was nutritional deficiencies (45%) followed by anemia of chronic inflammation (40%) and unexplained anemia (8%).

It is essential that anemia deserves its due attention in clinical practice in older patients and is not normal always.
