Granulomatous nephritis and chronic renal failure in sarcoidosis. Long-term follow-up studies in two patients.

Sarcoid granulomatous nephritis was observed in 2 patients. Renal failure was present in both patients in the absence of hypercalcemia or nephrocalcinosis. Specific tubular dysfunction manifested as an acquired Fanconi syndrome in 1 patient. Steroid therapy was effective in causing regression of the renal granuloma, but there were significant interstitial changes on repeat renal biopsy which were accompanied by persistent tubular dysfunction. Sarcoid granulomatous nephritis may be a not infrequent cause of renal dysfunction in sarcoidosis.

Monocytes and vascular lesions.

Current literature has shown increasing indications of the involvement of monocytes in the generation of vascular lesions and atherosclerosis. Such involvement appears to be mediated by the ability of monocytes to disrupt the integrity of blood vessel wall, initiate and accelerate blood coagulation processes and/or regulate the growth pattern of blood vessel wall cells. At least in two pathological situations, namely hypercholesterolemia and diabetes mellitus, the association between monocytes and atherogenesis is strongly indicated.

A definite case of spondylodiscitis caused by Streptococcus equisimilis.

To shed light on the role of Streptococcus equisimilis (SE) in the pathogenesis of intervertebral disc infection, we report here a case of lumbar spondylodiscitis in a 37-year-old male caused by SE, with identification of this strain by cultures from L4-L5 lumbar disc biopsy. Intravenous therapy with penicillin and gentamycin combined with immobilization resulted in a rapid and complete recovery. The patient did not have underlying disease and showed no obvious history of exposure to animals. We conclude that SE may be responsible for both septic arthritis and spondylodiscitis.

Diagnostic value of serum and synovial procalcitonin in acute arthritis: a prospective study of 42 patients.

OBJECTIVE: To determine the diagnostic value of serum and synovial procalcitonin (PCT) for bacterial arthritis and to determine the cellular origin of synovial PCT. METHODS: A prospective study enrolled 42 patients with acute arthritis including 11 bacterial arthritis, 18 rheumatoid arthritis and 13 crystal induced arthritis. Diagnostic values of serum and synovial PCT levels were determined by a immunoluminometric assay (Lumitest PCT) and compared to those of classical inflammatory markers (C-reactive protein, erythrocyte sedimentation rate, synovial fluid cellularity and both serum and synovial IL-6 and TNF alpha). Using fibroblast-like synoviocyte (FLS) cultures derived from rheumatoid arthritis (n = 4) and osteo-arthritis (n = 3) synovium, with or without stimulation by lipopolysaccharid or recombinant streptococcal protein 1/II, we attempted to determine whether synovial cells could be a source of PCT. RESULTS: Serum PCT was the best parameter to distinguish patients with acute bacterial arthritis from patients with crystal induced arthritis or rheumatoid arthritis. In setting of an acute arthritis serum PCT (> 0.5 ng/mL) achieved 55% sensitivity and 94% specificity for the diagnosis of bacterial arthritis, while CRP (> 50 mg/L) had 100% sensitivity but poor specificity (40%). Serum PCT appeared to be higher in patients with septic arthritis resulting from "systemic infection" than in cases resulting from direct inoculation. Synovial PCT was not useful to discriminate between infectious and non infectious arthritis in clinical practice. PCT could not be detected at significant levels in the conditioned medium from fibroblast-like synoviocyte cultures. CONCLUSION: Serum PCT is a poorly sensitive but specific marker of bacterial arthritis. Use of serum PCT in association with CRP could nevertheless be useful in an emergency situation for the diagnosis of bacterial arthritis.
