Objectives: To describe the initial clinical manifestations of Wegener's Granulomatosis (WG) in Brazil.
Patients and methods: Retrospective analysis of six medical records of WG patients followed-up at the Rheumatology Department of Hospital Geral of Fortaleza (HGF), as well as a bibliographic survey of cases of WG in Brazil on LILACS, SciELO, and MEDLINE databases.
Results: The study identified 49 patients, 15 (31%) males and 34 (69%) females. Systemic disease was observed in 35 patients (73%): 28 adults, 5 children, and 2 teenagers. Limited disease was observed in 13 adults and 1 child. The average age of onset in adults was 42.2 years (18 to 65 years). Acute clinical manifestations, with the onset of symptoms less than three months before the diagnosis, were observed in 41% (20/49) of the patients, and the insidious presentation in 59% (29/49) of the patients. The prevalence of the initial clinical manifestations in adults with systemic disease (n = 28) was 64% (18/28), upper airways, 36% (10/28), lungs, 18% (5/28), kidneys, 25% (7/28), eyes, 11% (3/28) skin, 25% (7/28), musculoskeletal, and 7% (2/28), neurological. In adults (n = 13) with limited disease, prevalent symptoms included: upper airway, 84% (10/13), eyes, 23% (3/13), and lungs, 15% (2/13).
Conclusion: The prevalence of the initial clinical manifestations of WG in Brazil was similar to that reported in the literature. The lack of specific symptoms may delay diagnosis cases with insidious presentation of the disease and increase the morbidity and mortality in acute disease.
