A combination of factors, including Western European eating habits, physical inactivity and genetic predisposition, lead to a dramatic increase in adipose tissue mass. A special place is occupied by abdominal obesity, in which there is an accumulation of adipose tissue in the mesentery of the small intestine and the omentum. Developing in conditions of visceral obesity, insulin resistance, dyslipidemia and systemic inflammation are one of the key components of the pathogenesis of type 2 diabetes mellitus, cardiovascular diseases, non-alcoholic fatty liver and pancreas disease, polycystic ovary disease, some forms of cancer (breast cancer, endometrial cancer, colonic and direct intestines). At the same time, the pathogenetic role of adipose tissue is not limited to its participation in the formation of the cardiometabolic continuum and oncogenesis. The most important role of metabolically active fat in the pathogenesis of many respiratory diseases is known, including bronchial asthma, obstructive sleep apnea and pulmonary hypertension. This paper presents an overview of current data on immunological, pathophysiological and clinical features of the phenotype of the combination of respiratory diseases with overweight and obesity.
Progressive pulmonary fibrosis is a major problem in respiratory medicine. Currently, there are no reliable biomarkers for early diagnosis of progressive pulmonary fibrosis, which leads to delayed diagnosis.
Aim. To determine the role of serum biomarkers CA-19-9 and CA-125 and the possibilities of capillaroscopy of the nail fold in the diagnosis of progressive pulmonary fibrosis.
Materials and methods. The study included 43 patients with interstitial changes in the lungs. Based on the presence/absence of signs of progression over the previous 12 months, patients were divided into 2 groups. All patients underwent forced spirometry, body plethysmography, diffusion test, CT, lung ultrasound, capillaroscopy of the nail fold, study of serum concentrations of CA-19-9 and CA-125.
Results. In the group of patients with a progressive fibrotic phenotype of Interstitial lung diseases, a greater severity of capillaroscopic changes and a higher level of CA-19-9 were revealed. Correlation of these parameters with changes according to CT scan data (Warrick test) and lung ultrasound was shown.
Conclusion. The data obtained demonstrate the possibilities of non-invasive diagnosis of progressive fibrosing interstitial lung diseases and require further research and prospective follow-up to assess the diagnostic and prognostic role of the studied biomarkers, as well as to determine their place in clinical practice.
