    Departamento de Medicina Interna, Hospital de Especialidades "Antonio Fraga Mouret", Centro Médico Nacional La Raza, Instituto Mexicano del Seguro Social, Ciudad de México, México.
    Background: Granulomatosis with polyangiitis (GP) is a systemic necrotizing vasculitis with multi-organ involvement that primarily affects the respiratory tract and the kidneys. Fever in these patients is an indicator of activity; however, if it arises in isolation, the physician should exclude other causes.

    Clinical Case: Male patient admitted due to an unexplained fever and weight loss; it was diagnosed GP by a history of pauci-immune glomerulonephritis, fixed pulmonary nodules and chronic sinusitis of four years of evolution; however, the fever persisted despite treatment and in the absence of infection.

    Aim: We investigated what variables at diagnosis might be associated with the relapse of eosinophilic granulomatosis with polyangiitis (EGPA) and whether five factor score (FFS) at diagnosis might predict it.

    Methods: We reviewed the medical records of 30 patients with EGPA having results of myeloperoxidase (MPO)-antineutrophil cytoplasmic antibodies (ANCA) and proteinase 3 (PR3)-ANCA and having achieved remission during the first therapeutic regimen administration within follow-up duration for at least more than 2 years. Clinical manifestations, the presence of relapse and items for FFS at diagnosis were collected and compared among groups. Read More
