Abstract
Background: In 1972, Dr Sharp and colleagues described a new connective tissue disease, characterized by overlapping features of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and polymyositis/ dermatomyositis (PM/DM) and by the presence of antibodies against the U1 small nuclear ribonucleoprotein autoantigen (U1 snRNP). This condition was termed mixed connective tissue disease (MCTD) and proposed as a distinct disease. Later, after observing the clinical evolution of MCTD patients, Sharp himself agreed that the original concept of MCTD had to be modified and that Internal organs were at risk for serious complications; patients were not always steroid responsive; prognosis was not always benign. Materials and methods: Patients in the age group of 15-50 years diagnosed to have connective tissue diseases were included. 8 patients in the age group of 15-50 admitted in Medicine department were taken and they were evaluated for the clinical profile of sharp syndrome by thorough clinical examination, routine laboratory tests and special investigations depending on the clinical profile. Results: 8 patients with connective tissue disease attending the medicine OPD were studied. Of these 8 patients were female patients. The median age of onset was 36 years, 8 patients met criteria by sharp and Alarcon-Segovia. The clinical features of patients at presentation are Raynaudæ¯ phenomena, Puffy fingers, esophagus dysmotility, skin rash, interstitial lung disease, arthritis, pulmonary hypertension, myositis, anemia. Conclusion: SHARP syndrome is a rare condition, as evidenced by the small series of cases reported to date. Diagnosis is based on clinical and paraclinical criteria. The evolution can be interspersed with various complications that can affect the short, medium and long-term prognosis
