Introduction: Chronic obstructive pulmonary disease (COPD) is a progressive condition and a leading cause of morbidity and mortality worldwide. The rate of forced expiratory volume in one second (FEV1) decline is a key prognostic marker. This study aimed to evaluate the impact of demographic, clinical, and therapeutic factors, including respiratory muscle strength and inhaled corticosteroid (ICS) use, on FEV1 decline.Methods: A prospective study was conducted in 2019 at the Clinic for Pulmonology, Clinical Center of Serbia. Fifty patients with stable COPD underwent spirometry, body plethysmography, respiratory muscle strength testing, and laboratory analyses. Demo-graphic and clinical data were collected via questionnaire. All assessments were repeated after six months of regular inhalation therapy.Results: Significant reductions were observed in FEV1, FVC, TLC, PImax, and PEmax. Lower baseline respiratory muscle strength predicted a faster FEV1 decline. Patients in GOLD stage 2 and those with greater hyperinflation exhibited accelerated functional deterioration. Therapy type affected selected parameters: LABA/ICS and LAMA/LABA/ICS regimens significantly reduced residual volume, but not the rate of FEV1 decline. Higher eosinophil counts were associated with a slower reduction in FEV1, suggesting a potential protective effect of ICS.Conclusion: Respiratory muscle strength, hyperinflation, and eosinophil count represent important predictors of COPD progression. Incorporating these parameters into diagnostic and therapeutic algorithms may improve early risk stratification and support indi-vidualized treatment strategies.

Elevated MMP9 Expression – a Potential In Vitro Biomarker for COMPopathies

The intracellular retention of misfolded extracellular matrix proteins is a common disease mechanism in various individually rare skeletal diseases. This discovery has driven the study of ER-stress and the unfolded protein response (UPR) as a promising therapeutic target in several skeletal dysplasias. In the case of COL10A1 mutations, targeting the UPR resulted in a clinical trial of the repurposed drug carbamazepine; however, for other closely related skeletal disorders treatment with carbamazepine was ineffective, indicating the need for suitable markers for in vitro screenings of potential drug treatments. Mutations in cartilage oligomeric matrix protein (COMP), a cartilage structural protein, causes both multiple epiphyseal dysplasia (MED) and pseudoachondroplasia (PSACH); together referred to as COMPopathies, and result in intracellular retention of mutant COMP protein to varying degrees. In contrast to other closely related skeletal disorders, caused by mutations in cartilage structural proteins, the involvement of the UPR is less clear, and so far, no common COMPopathy marker has been identified. Here, using cell models of COMPopathies we identified MMP9 upregulation as a common feature of six pathogenic COMP variants that do not induce a prominent UPR. We further show that the archetypal p.V194D matrilin-3 MED variant (which causes MED), does not induce MMP9 expression, suggesting that MMP9 upregulation could serve as a specific marker of COMPopathies in vitro.
