Write answer in between .Q:A 33-year-old Caucasian female presents to her primary care provider for skin problems and difficulty breathing. She has not sought medical care in over 10 years due to anxiety around physicians. However, she has experienced gradual onset of diffuse pruritus, skin induration, and limited finger mobility over the past 5 years that has negatively impacted her work as an accountant. More recently, she has developed exertional shortness of breath and is concerned that it may impact her ability to care for her 3-year-old son. She reports no prior medical conditions and takes fish oil. She smokes 1 pack of cigarettes per day and drinks socially. Her temperature is 98.6F 37C, blood pressure is 14585 mmHg, pulse is 85min, and respirations are 22min. On exam, she appears anxious with minimally increased work of breathing. Dry rales are heard at her lung bases bilaterally. Her fingers appear shiny and do not have wrinkles on the skin folds. A normal S1 and S2 are heard on cardiac auscultation. This patients lung disease is caused by increased secretion of which of the following substances within the lungs?? A: Interferon gamma, B: Interleukin 1, C: Interleukin 2, D: Tumor necrosis factor alpha, E: Transforming growth factor beta,  <response>: This is a clinical vignette describing a 33-year-old female patient presenting with skin and respiratory symptoms that have progressed over several years. The key findings are diffuse pruritus, skin thickening, limited finger mobility, exertional dyspnea, dry rales on lung exam, and shiny fingers without skin wrinkles. This constellation of symptoms and physical exam findings is most consistent with systemic sclerosis scleroderma, an autoimmune disease characterized by fibrosis of the skin and internal organs such as the lungs. The question asks which substance is increased in the lungs of this patient and responsible for the lung disease. The choices list various cytokines or growth factors. Systemic sclerosis is associated with increased secretion of transforming growth factor beta TGF-β, which promotes tissue fibrosis. Therefore, the answer is likely choice E.E: Transforming growth factor beta
