SUMMARY A retrospective study showed musculoskeletal manifestations in 32 of 108 patients treated for infective endocarditis in several departments at the Poitiers CHU. Such manifestations included articular pain or aseptic arthritis, typically involving the major joints, as well as vertebral osteomyelitis, low back pain (inflammatory or non-inflammatory), and myalgia.Patients showing such signs were generally younger than those without musculoskeletal involvement, diagnosis was made later, and prognosis was worse; streptococcus D was more often involved, and microscopic haematuria was more common. With the exception of vertebral osteomyelitis, the pathogenesis was not clear.

Since 1984, there have been several reports of a destructive spondylarthropathy occurring in patients who have received hemodialysis over a long period of time. Two cases of a similar syndrome were observed in nonhemodialyzed patients with chronic renal failure, one of whom underwent a lumbar disc excision. The results of disc examination and of radiographic and biologic investigations prompted reconsideration of factors previously considered to be pathogenetic (amyloidosis, hydroxyapatite crystal deposition, aluminum toxicity), except one: secondary hyperparathyroidism.
