Inflammatory markers in geriatric anemia: A study from North India

Area of Science:

• Geriatric Medicine
• Hematology
• Immunology

Background:

• Inflammation's role in geriatric anemia, including iron deficiency anemia (IDA), anemia of chronic disease (ACD), and unexplained anemia (UA), is not fully understood.
• Limited data exists on inflammatory patterns in anemic geriatrics and inflammation's role in UA.
• The overlap between inflammation in ACD and UA requires further investigation.

Purpose of the Study:

• To determine the proportion of anemic geriatric patients (≥60 years) with elevated serum inflammatory markers.
• To analyze these inflammatory patterns within IDA, ACD, and UA categories.

Main Methods:

• Seventy-five anemic geriatric patients were assessed.
• Serum levels of high-sensitive C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) were measured.
• Serum ferritin (SF) levels were also evaluated.

Main Results:

• Elevated inflammatory markers were observed in 94.7% of anemic geriatric patients.
• Interleukin-8 (IL-8) was the most frequently elevated marker, followed by TNF-α, IL-6, hsCRP, and SF.
• No distinct inflammatory profile differentiated ACD from UA.

Conclusions:

• A hyperinflammatory profile is common in geriatric anemia, regardless of the specific cause.
• Aging may inherently be a pro-inflammatory state contributing to anemia.
• Geriatric anemia likely develops from subclinical inflammation combined with nutritional deficiencies or chronic diseases.
