The purpose of the study was to determine the clinical and laboratory features of inflammatory phenotypes among patients with chronic obstructive pulmonary disease, moderate respiratory failure and anemia of chronic disease. Materials and methods. The study included 150 patients with exacerbation of chronic obstructive pulmonary disease and chronic anemia, in which inflammatory phenotypes were identified, among which the largest share was neutrophilic (66/44.0±4.0%), less lymphocytic (35/23.3±3.4%) and eosinophilic (16/10.7±2.5%). In 33/22.0% of patients, the inflammatory phenotype was mixed and patients were excluded from the study. Among 117 patients included in the study, 67.5% were men and 32.5% were middle-aged (25.6%), elderly (42.7%) and senile (24.8%). The results were processed by the methods of variation statistics, the materiality threshold p <0.05. Results and discussion. It was established, that peripheral blood analysis and biochemical parameters, regardless of the pathophysiological nature of inflammation in all groups showed moderate dysfunction of external respiration, normochromic normocytic nature of mild chronic anemia with activation of all components of the external coagulation mechanism and increased prothrombin time and inflammation activation (by C-reactive protein and seromucoids). The neutrophilic phenotype of inflammation, in comparison with lymphocytic and eosinophilic, was the most common and was accompanied by the most pronounced anemic syndrome, the highest activity of systemic inflammation and the most pronounced syndrome of endogenous intoxication with deterioration of liver function. The lymphocytic phenotype of inflammation was the second widespread and was characterized by the most pronounced normochromic anemic syndrome with the most pronounced predisposition to hypercoagulation (the highest prothrombin index) with high activity of the inflammatory syndrome. The eosinophilic phenotype of inflammation was significantly less common than the neutrophilic and lymphocytic with the favorable characteristics of the anemic syndrome and with low inflammatory activity and the small activity of endogenous intoxication but the highest fasting blood glucose level as normo-hyperglycemia. Conclusion. Clinical and pathophysiological phenotyping of chronic obstructive pulmonary disease makes it possible to determine not only the activity of inflammation, but also the severity of anemic syndrome, endogenous intoxication, liver status and carbohydrate metabolism, which is of practical importance for both physicians and scientists
