Lymphadenopathy is palpable enlargement of lymph nodes. Inflammation is a normal part of your bodys response to injuries and invaders. It promotes healing and helps you feel better.Inflammation is a vital biological mechanism that acts as the bodys primary defense against harmful agents, such as pathogens, damaged cells, and irritants. Although acute inflammation is important for healing and recovery, chronic inflammation may result in various diseases, including cancer, cardiovascular issues, and autoimmune disorders. Inflammation can arise from numerous causes of lymphadenopathy, including microbial infections, autoimmune diseases, cancers, and other factors that contribute to elevated inflammatory markers in the bloodstream. Inflammatory markers as Erythrocyte sedimentation rate (ESR) and C Reactive Protein (CRP) were measured in serum of children with lymphadenopathy to help for monitoring the inflammation state. The erythrocyte sedimentation rate and C-reactive protein are among the oldest laboratory tests still in use. The results Showed that, there was significant increase in Erythrocyte sedimentation rate in first and second hour in children with lymphadenopathy compared to healthy control children (P value = 0.001) (P value = 0.001) respectively. There was also significant increase in serum level of C Reactive Protein in children with lymphadenopathy compared to healthy control children (P value = 0.007).
