UTILITY OF CLINICAL PATHOLOGY IN DIAGNOSING AUTOIMMUNE DISEASES. 

Abstract:

Autoimmune diseases are a diverse group of disorders characterized by abnormal immune responses against self-tissues. Diagnosing autoimmune diseases can be challenging due to their complex and heterogeneous nature, as well as overlapping clinical manifestations. Clinical pathology, which encompasses various laboratory tests, plays a crucial role in the diagnosis of autoimmune diseases. This abstract highlights the utility of clinical pathology in the diagnosis of autoimmune diseases, focusing on serological, hematological, and histopathological investigations.

Serological tests, such as autoantibody assays, are valuable tools for identifying specific autoantibodies associated with different autoimmune diseases. The presence of autoantibodies, such as antinuclear antibodies (ANAs), anti-cyclic citrullinated peptide (anti-CCP) antibodies, and anti-double-stranded DNA (anti-dsDNA) antibodies, can aid in the diagnosis and classification of diseases such as systemic lupus erythematosus, rheumatoid arthritis, and systemic sclerosis. These tests provide valuable information for clinicians, helping to differentiate between autoimmune and non-autoimmune conditions and guiding appropriate treatment strategies.

Hematological investigations, including complete blood counts (CBC) and erythrocyte sedimentation rate (ESR), contribute to the diagnosis and monitoring of autoimmune diseases. CBC can reveal abnormalities such as leukopenia, thrombocytopenia, or anemia, which are common in conditions like systemic lupus erythematosus or immune thrombocytopenic purpura. ESR, a non-specific marker of inflammation, can be elevated in various autoimmune diseases, indicating ongoing disease activity.

Histopathological examinations of tissue samples obtained through biopsies provide critical diagnostic information for autoimmune diseases affecting specific organs. Pathological features observed in the tissues, such as lymphocyte infiltration, tissue damage, and deposition of immune complexes, can help establish a definitive diagnosis. Examples include kidney biopsies in lupus nephritis or skin biopsies in dermatomyositis.

In conclusion, clinical pathology plays a vital role in the diagnosis and management of autoimmune diseases. Serological tests, hematological investigations, and histopathological examinations provide valuable information for clinicians, aiding in the identification of specific autoimmune conditions, differentiation from other diseases, and monitoring disease activity. A comprehensive understanding and integration of clinical, serological, hematological, and histopathological findings are essential for accurate diagnosis and optimal management of patients with autoimmune diseases.
