Hematological and clinical profiling of chronic obstructive pulmonary disease: a comprehensive study.

Chronic obstructive pulmonary disease (COPD) presents as a multifaceted clinical landscape with various hematological manifestations. Among these, polycythemia and anemia pose distinct challenges. While the prevalence of polycythemia has decreased in recent years, anemia remains a prevalent concern, impacting patient outcomes. This study investigated the incidence and clinical characteristics of polycythemia in COPD patients, focusing on a diverse cohort in India. Methodological approaches included comprehensive evaluations of clinical parameters, pulmonary function, and hematological profiles. Results revealed significant variations in COPD severity, pulmonary function, and respiratory symptoms among patients with different hemoglobin levels. The findings shed light on the complex interplay between hematological variations and clinical manifestations in COPD, providing valuable insights for disease management strategies.
