Vascular complications in systemic sclerosis: a prospective cohort study.

Area of Science:

• Rheumatology
• Pulmonology
• Cardiology

Background:

• Scleroderma (systemic sclerosis) is associated with significant morbidity and mortality due to complications like ischemic digital lesions (DL) and pulmonary hypertension (PH).
• Accurate prediction of these complications in scleroderma patients remains a clinical challenge.

Purpose of the Study:

• To identify predictive clinical features for the development of pulmonary hypertension (PH) and digital lesions (DL) in a cohort of scleroderma patients.
• To assess the long-term risk of PH and DL development in patients without these complications at baseline.

Main Methods:

• A prospective observational cohort study involving 300 scleroderma patients.
• Patients were followed for at least 5 years, with examinations every 6 months for signs of PH or DL.
• Primary outcomes included PH diagnosis (mean pulmonary artery pressure ≥ 25 mmHg) and development of ≥ 1 DL (severe vascular compromise).

Main Results:

• 10% of patients developed PH (30/300), with an average diagnosis time of 3.2 years.
• 69 patients developed DL.
• Predictors for PH included diffuse disease, FVC/DLCO ratio > 1.6, and elevated RVSP. Predictors for DL included prior DL history and male sex.

Conclusions:

• Simple, measurable clinical features can predict the future development of PH and DL in scleroderma patients.
• Early identification of at-risk individuals allows for proactive management and potentially improved outcomes in scleroderma care.
