Collagen Fingerprinting for Stratification of Pulmonary Hypertension (PH) Patients

Status: Recruiting
Location: See location...
Study Type: Observational
SUMMARY

Chronic lung diseases such as pulmonary fibrosis and chronic obstructive pulmonary disease (COPD) can lead to pulmonary hypertension. This serious complication involves increased pressure in the lung vessels, which strains the heart and worsens outcomes. Since the early symptoms are unclear, diagnosis often occurs too late, underscoring the need for simple, noninvasive methods of early detection. A key driver of the disease is vascular remodeling, which involves the narrowing and stiffening of blood vessels. This process involves changes in the extracellular matrix, particularly in the understudied basement membrane. Our project examines how specific components, especially non-classical collagens, change during disease progression. As vessels remodel, detectable fragments enter the bloodstream, potentially creating a molecular fingerprint of the disease. By analyzing lung tissue and blood samples, the investigators aim to identify non-invasive biomarkers for earlier diagnosis, better patient classification, and more personalized treatment.

Treatments
Patients with confirmed COPD with or without pulmonary hypertension (COPD/PH group)
Tissue Sampling Blood is collected via venipuncture into citrate- or ethylenediaminetetraacetic acid (EDTA)-containing Vacutainer tubes, as well as into serum tubes. Obtain explant lung tissue from patients who have undergone lung transplantation.
Patients with confirmed pulmonary fibrosis with or without pulmonary hypertension (PF/PH group)
Tissue Sampling Blood is collected via venipuncture into citrate- or ethylenediaminetetraacetic acid (EDTA)-containing Vacutainer tubes, as well as into serum tubes. Obtain explant lung tissue from patients who have undergone lung transplantation.
Patients with confirmed pulmonary arterial hypertension (PAH group)
Tissue Sampling Blood is collected via venipuncture into citrate- or ethylenediaminetetraacetic acid (EDTA)-containing Vacutainer tubes, as well as into serum tubes. Obtain explant lung tissue from patients who have undergone lung transplantation.
Control group without diagnosed COPD, PF or pulmonary hypertension (Control group)
Tissue Sampling Blood is collected via venipuncture into citrate- or ethylenediaminetetraacetic acid (EDTA)-containing Vacutainer tubes, as well as into serum tubes. Explant lung tissue is obtained from patients who have undergone lung transplantation.~Non-transplanted donor lungs that were harvested for transplantation but not implanted due to size reduction serve as controls.
