Lack of association with spondyloarthritis and HLA-B27 in Italian patients with Whipple's disease.
OBJECTIVE: To examine consecutive patients with Whipple's disease (WD) for the full clinical spectrum of spondyloarthritis. METHODS: Nine consecutive patients, 8 men, 1 woman, with WD were clinically evaluated and examined for clinical and radiological manifestations of spondyloarthritis by 2 rheumatologists with special interest in spondyloarthritis. The mean age of the patients at the time of study and at the time of their initial diagnosis of WD by duodenal biopsy was 62.4 years (range 42-71) and 54.4 years (range 40-62), respectively. Each patient had an anteroposterior radiographic view of the pelvis and also had HLA typing for class I and II alleles. Pelvis radiographs were read blindly for evidence of sacroiliitis. RESULTS: All but one patient had rheumatologic manifestations related to WD. The mean interval between the onset of these symptoms and the diagnosis of WD was 6.1 years (range 1-15). One had recurrent polyarthritis, 1 recurrent oligoarthritis, 3 recurrent monoarthritis, 2 recurrent synovitis with pitting edema of the dorsum of hands and/or feet, and 1 isolated De Quervain's tenosynovitis. Of the 5 patients with arthritis, 3 also had episodes of swelling with pitting edema over the dorsum of hands and/or feet together with flexor digit tenosynovitis, 2 also had olecranon bursitis, and 1 tibial tenosynovitis. No patient had clinical or radiological manifestations of spondyloarthritis. None had the HLA-B27. CONCLUSION: In Italian Caucasian patients with WD there was no association with spondyloarthritis and HLA-B27.
