Anaemia in Newly Diagnosed Patients of Rheumatoid Arthritis and its Correlation with Disease Activity

To detect frequency of anemia in patients of Rheumatoid arthritis (RA) and to establish relationship between hemoglobin level and disease activity in RA.

Fifty nine patients of RA fulfilling 2010 ACR/EULAR criteria of RA having disease duration less than two years were included in the study. Haemoglobin (Hb) levels were measured. Disease activity was assessed by DAS-28 score.

Among 40/59 (67.80%) anemic cases, 22/40 (55%) patients had anaemia of chronic disease (ACD), 11/40 (27.50%) patients had Iron deficiency anemia (IDA), 3/40 (7.5%) patients had vitamin B(12) deficiency, 1/40 (2.50%) patient had folate deficiency and 3/40 (7.50%) patients had combined IDA and vitamin B(12) deficiency. Duration of disease, rheumatoid factor positivity and occurrence of erosive disease were not significantly different among anaemic and nonanaemic patients (p>0.05 for each). Mean ESR (p>0.02) and DAS-28 (p>0.001) were statistically significantly different among anaemic and nonanaemic patients. Haemoglobin level had significant negative correlation with disease activity (DAS28) in RA cases (r -0.5533, p<0.0001). Conclusion: Anemia was seen in higher frequency in RA patients. Haemoglobin had significantly negative correlation with disease activity (DAS 28) in RA. .

Anemia was seen in higher frequency in RA patients. Haemoglobin had significantly negative correlation with disease activity (DAS 28) in RA.
