Abstract
Since the start of the global pandemic caused by coronavirus disease 2019 (COVID-19), there have been numerous reports of autoimmune and rheumatological disorders developing after infection with SARS-CoV-2. To date, there has been only one reported case of systemic sclerosis (SSc) developing after SARS-CoV-2 infection. Here, we present another case of SSc developing after infection with SARS-CoV-2. A 48-year-old female with past medical history of anxiety and depression presented to the rheumatology clinic after being referred for further evaluation of abnormal labs, Raynaud's phenomenon, and other concerning symptoms. Shortly after hospitalization for COVID-19 pneumonia, she began experiencing symptoms that included fatigue, xerostomia, dysphagia, bilateral lower extremity weakness, dyspnea with exertion, unintentional weight loss, and diffuse skin hyperpigmentation. Labs ordered shortly before presentation were significant for antinuclear antibody (ANA) titer > 1:1280. Physical exam was remarkable for puffy fingers, sclerodactyly of the fingers, diffuse skin hyperpigmentation, and abnormal nailfold capillaries. Anti-RNA polymerase III, anti-Scl-70, anti-centromere, anti-SSA, anti-SSB, anti-Smith, and anti-Smith/RNP antibodies were all negative. BNP, aldolase, and serum myoglobin levels were within normal limits while creatine phosphokinase level was slightly decreased. Pulmonary function testing showed reduced diffusion capacity with normal lung mechanics and volumes. High-resolution CT scan of the chest showed interstitial lung disease, with findings suggestive of nonspecific interstitial pneumonia. Transthoracic echocardiogram showed mild elevation of right ventricular systolic pressure, but pulmonary hypertension was not found on right heart catheterization. Esophagogastroduodenoscopy (EGD) with biopsy performed for evaluation of esophageal dysphagia showed sliding hiatal hernia, irregular Z-line, and gastric hyperemia. Biopsy of the distal esophagus was consistent with Barrett's esophagus. The patient was diagnosed with SSc according to the 2013 American College of Rheumatology/European League Against Rheumatism (ACR-EULAR) classification criteria for SSc. She is currently being treated with mycophenolate mofetil, amlodipine, methotrexate, and prednisone.
