Abstract
Anti-glomerular basement membrane (GBM) disease is an autoimmune disorder with rapidly progressive glomerulonephritis and alveolar hemorrhage. Fever symptom and prodromal infections have been reported in many cases, but still not been elucidated. Our study enrolled 140 consecutive patients with anti-GBM disease and retrospectively analyzed the characteristics of fever symptom and the possible reasons. Among the 140 patients, 94 (67.1%) patients presented with fever (over 37.5 °C) prior to admission or within 48 hours of hospitalization. Among those with fever, 74 (78.7%) patients had infections, 15 (16.0%) patients had positive serum ANCA, all towards MPO, which was comparable to the patients without fever (17.4%, P = 0.830). There were 93/140 patients suffered from infections, with 47.3% in lungs and 31.2% on upper respiratory tract. In some cases, we identified the microbes of infections, including Candida albicans, Escherichia coli, Acinetobacter baumannii, Enterococcus faecalis, Klebsiella pneumoniae, Hemolytic staphylococci, Pseudomonas aeruginosa and Citrobacter braakii. Patients with fever had higher levels of serum anti-GBM antibodies (154.9 ± 58.4 vs. 106.0 ± 63.2 IU/ml, P < 0.001), higher serum creatinine (733.4 ± 402.5 vs. 580.6 ± 368.1 µmol/L, P = 0.032), higher percentage of crescents (87.0 ± 15.6 vs. 67.4 ± 37.6%, P = 0.021), and higher frequency of progression to end stage renal disease (ESRD) (80.9% vs. 60.9%, P = 0.011). We concluded that fever is a common symptom in anti-GBM disease and associates with more severe glomerulonephritis. The majority of patients at presentation had fever with respiratory tract infections, which needs further investigation to reveal their role in the pathogenesis of anti-GBM disease.Funding Information
