Background and study aims
Systemic sclerosis (SSc) is a rare autoimmune disease, caused by the immune system attacking the connective tissue under the skin and around internal organs and blood vessels. This causes scarring and thickening of the tissue in these areas.
Pulmonary hypertension is high blood pressure in the blood vessels that supply the lungs (pulmonary arteries). It's a serious condition that can damage the right side of the heart. The walls of the pulmonary arteries become thick and stiff, and cannot expand as well to allow blood through.
Pulmonary hypertension is the leading cause of death in systemic sclerosis (SSc) and affects up to 12% of all patients with SSc.
The aim of this study was to evaluate the diagnosis, profile, and prognosis of systemic sclerosis pulmonary hypertension (SSc-PH) diagnosed by systematic screening in a Brazilian population.

Who can participate?
Patients aged 18 years and above with SSc.

What does the study involve?
The study involves the performance of a systematic screening procedure for the diagnosis of systemic sclerosis-related pulmonary hypertension. Then, the study performed a three-year follow-up of the included patients. Patients with positive screening underwent right heart catheterization.

What are the possible benefits and risks of participating?
Potential benefits: patients who participate have the chance to receive an early diagnosis of pulmonary hypertension. This affords early treatment and may alleviate symptoms, improve quality of life. We speculate that early treatment could improve survival.
Potential risks: to confirm the diagnosis of pulmonary hypertension, the patients referred by the screening had to undergo right heart catheterization. This is an invasive haemodynamic procedure. Right heart catheterization has the risks of bleeding, heart arrhythmias, vessel perforation, allergic reaction to iodine contrast, heart failure and very rarely death.

Where is the study run from?
University Hospital Pedro Ernesto (Brazil)

When is the study starting and how long is it expected to run for?
June 2012 to July 2020

Who is funding the study?
Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro (Foundation to Sponsor Research in Rio de Janeiro) (Brazil)

Scientific titlePulmonary hypertension in systemic sclerosis: diagnosis by systematic screening and prognosis after a three-year follow-up
Study objectivesA systematic screening to achieve early diagnosis of systemic sclerosis-related pulmonary hypertension can be performed. The profile and prognosis of the patients diagnosed by this screening should be described.
Ethics approval(s)Approved 24/03/2013, Local ethics committee University Hospital Pedro Ernesto (Boulevard 28 de Setembro 77 Vila Isabel CePeM – Centro de Pesquisa Clínica Multiusuário – 2º andar/sala 28, prédio anexo ao Hospital Universitário Pedro Ernesto, Rio de Janeiro, Brazil; +55 21 2868-8253; cep@hupe.uerj.br), ref: 314.092
Health condition(s) or problem(s) studiedPulmonary hypertension related to systemic sclerosis
InterventionAll patients with systemic sclerosis in treatment at our referral centre were invited to be included between 01/07/2014 until 01/07/2017. Included patients underwent a systematic screening for pulmonary hypertension that included transthoracic echocardiography and the multiple tools required by the DETECT algorithm. Patients were referred to right heart catheterization if the screening was positive. The profile of the patients diagnosed by this screening was described. The prognosis was evaluated by a three-year follow-up.
Intervention typeProcedure/Surgery
Primary outcome measureDiagnosis of pulmonary hypertension at baseline (yes/no) measured using patient records
Secondary outcome measures1. Survival measured using patient records at 3 years
2. Worsening of condition from baseline measured using patient records at 3 years
Overall study start date15/06/2012
Completion date01/07/2020

IPD sharing planThe datasets generated during and/or analysed during the current study are available from the corresponding author on reasonable request: vilelavs@gmail.com
Type of data: demographic, screening tools, screening results, clinica, serum and immunological data, haemodynamic data. All datasets are on Excel sheets where anonymisation was made by replacing patients dentifications by numbers (codes). The criteria for the access to the data is to send e-mail for the main author with reasonable request. Data will be available as soon as requested by email (within one or two weeks). Once shared, data will be permanently available. As patient identifications are not disclosed in the sheets, consent from participants to share data was not obtained. There are no legal and ethical restrictions for this data sharing.
