Scleroderma Presenting with Pulmonary Hypertension Cara Fininzio, D.O. Research Symposium June 9, 2010
Background • Scleroderma (systemic sclerosis) is rare multisystem disease, causing fibrosis of multiple organ systems • Skin, kidneys, lungs, GI tract, heart, and blood vessels can be affected • Two forms are identified but there can be some overlap
Background • Diffuse cutaneous • Rapid development of symmetric skin thickening • Greater risk for other visceral disease early in course • Limited cutaneous • Symmetric thickening of skin on distal extremities/ face • Can have features of CREST
Background • Diffuse: • Distal and proximal extremities, trunk, and face skin involvement • Raynaud’s phenomenon at onset or within 1 year of skin changes • Pulmonary involvement (fibrosis), renal, GI, cardiac • Antitopoisomerase I AB
Background • Limited: • Distal extremity/ face skin involvement • Raynaud’s may precede by years • GI, PAH after 10-15 years of disease, biliary cirrhosis • Anticentromere AB

Workup • Admitted with decompensated CHF • BNP 3360, mild bilateral pleural effusions and cardiomegaly on CXR, TnI 0.040.080.05 • Pulmonology consult- pHTN unclear etiology consider primary, ANA, RF, Lupus anticoagulant, complete PFT with DLCO, consider right heart catheterization and possible Revatio or Bosantan
Workup • Renal consult for Stage IV renal failure • Recommended discontinue ACE inhibitor, lasix, avoid IV contrast and NSAIDS, testing ordered for autoimmune cause, consider mediastinal LN biopsy to rule out lymphoma/ sarcoidosis
Workup • Normal Esophogram and Upper GI with small bowel follow through • Renal US unremarkable • Renal flow scan showed mild-moderate chronic parenchymal dysfunction bilaterally
Workup • 2D Echo 2/21/2009 - LVEF 60%, moderate to severe PAH with RVSP 64mmHg, LVH, diastolic dysfunction • 2D Echo on 3/25/09 - LVEF 55%, severe PAH with RVSP 60-80mmHg, severely enlarged right atrium/ ventricle, impaired diastolic function

Summary Our patient: • Positive ANA and SCL-70 Ab • PAH with RVSP of 60-80mmHg on Echo • Raynaud’s phenomenon and thickened mildly erythematous skin changes
Summary • Our patient was treated with supplemental oxygen and was referred to Hospice care due to rapid progression of her symptoms and decline in physical function • She died three months after the diagnosis of scleroderma was made
Scleroderma • Mortality rate for systemic sclerosis has been a constant increasing trend for the past several decades [1] • Increased knowledge and understanding of scleroderma may be contributing to the increasing prevalence [1] • Apparent increased mortality of the disease seen from 1999-2002 [1]
Scleroderma • A study by Mendoza showed age-adjusted mortality of systemic sclerosis was 3.2 times greater in women than men [1] • Mortality of this disease continues to trend upward due to the lack of a specifically targeted cure, but improvements in survival have been noted [1] • Most likely explained by decreased morbidity from better management of pulmonary hypertension and renal crisis than in the past [1]
Pulmonary Hypertension • Commonly seen pathologic process and often the cause of death in multiple connective tissue disorders, including systemic sclerosis [2] • Up to 40% of patients with scleroderma have been reported to have pulmonary hypertension [2] • Those with the limited form seem to have an increased risk compared to those with diffuse skin disease [2]
Pulmonary Hypertension • PAH is important in determining the prognosis in patients with systemic sclerosis [2] • Increased risk of developing pulmonary hypertension with positive U3RNP/ fibrillation and anticentromere antibodies [2] • Decrease with antitopoisomerase (Scl-70) antibodies [2]
Raynaud’s and Scleroderma • Diffuse intimal proliferation causes occlusion of the lumen in blood vessels [3] • Leads to the narrowing and vasculopathy seen in pulmonary vascular disease as well as digital vessel pathology (i.e. Raynaud's) [3] • Raynaud's disease has been shown to be an associated risk factor for pulmonary hypertension in patients with systemic sclerosis [3]
Raynaud’s and Scleroderma • Showed that patients with pulmonary hypertension had a longer duration of Raynaud's at the time of diagnosis compared to those without pulmonary hypertension and scleroderma [3] • In the patients with pulmonary hypertension the DLCO was very low at the time of diagnosis [3] • The pulmonary artery systolic pressures were found to be >70mm Hg [3]
Raynaud’s and Scleroderma • Steen found their group of patients with long duration (greater than 10 years) of Raynaud's to have severe pulmonary hypertension with right heart changes • Determined that patients should be suspected to have pulmonary hypertension if they have had longstanding limited disease, ANA or anticentromere, PASP >40 mm Hg or DLCO <65% predicted [3]
Testing Modalities • Echocardiogram, PFTs, exercise testing, and serum biomarkers are among the most common and effective screening modalities for pulmonary hypertension [4] • In symptomatic patients, echocardiography has a 90% sensitivity and 75% specificity for detecting moderate to severe pulmonary artery pressure elevations [4]
Testing Modalities • Several studies have examined exercise echocardiography in patients with scleroderma and reported elevated pulmonary artery pressures [4] • They were not confirmed with right heart catheterization • DLCO in pulmonary function testing was found to show a linear decrease over 15 years in patients with systemic sclerosis who would eventually develop pulmonary hypertension [3]
Testing Modalities • The 6MWD (6 minute walk distance) showed to be useful in assessment of severity of pulmonary hypertension [4] • Has not been used specifically to screen for it in patients with systemic sclerosis • BNP has been used as a marker of right ventricular dysfunction in patients with pulmonary hypertension due to systemic sclerosis [4] • It has not been validated to be a good screening tool alone
Conclusion • This report demonstrates the effects of scleroderma on the lungs demonstrated by rapidly progressing symptoms from pulmonary artery hypertension in our patient • Our patient did complain of pruritis several months prior to her pulmonary symptoms • likely were due to skin changes and tightening secondary to underlying to scleroderma
Conclusion • During her visits with a previous physician she was complaining of pruritis and treated symptomatically with PO antihistamines • Diagnosis of Raynaud’s phenomenon for several years before she presented with pulmonary symptoms • History of alcohol abuse and cardiomyopathy may also have contributed to delay in workup and diagnosis of scleroderma
Conclusion • Although a small percentage of patients with Raynaud’s will end up developing scleroderma, it was an early sign of our patient’s disease • Recognition and complete evaluation would not necessarily have changed the disease course or outcome of our patient • Earlier recognition of the signs and symptoms of scleroderma may have led to an earlier diagnosis in our patient
