We describe the case of a 76-year-old man with hypertension who had been treated for gout for 20 years on allopurinol and colchicine. He was seen in consultation for deforming polyarthritis of the small and large joints, which had been evolving for about 2 years. The acute episode occurred 10 days earlier with the onset of bilateral and symmetrical polyarthritis affecting the large and small joints. The physical examination revealed a peripheral joint syndrome with ulnar gale force deformities of the hands and several buttonhole deformities of the fingers. In addition, there were nodules, some of which were fistulised, giving rise to a chalky slurry. The biology revealed an inflammatory syndrome in addition to rheumatoid factors and ACPA, which were elevated. Biological analysis of the nodular fluid revealed clusters of sodium urate crystals and ultrasound scans of the joints revealed a double-contour appearance in several joints. The diagnosis of RA was made using the 2010 ACR/EULAR criteria. The patient was treated as an outpatient with corticosteroids before being put on methotrexate. It is important to understand that these two conditions can occur at the same time, so it is important to consider them when treating patients with gout or RA.展开更多

This may cause gouty arthritis in joints and tophi in soft tissues. Spinal gout is rare and never mentioned in our context. It can appear as acute back pain, radiculopathy, spinal cord compression, spondylodiscitis or neoplasic/infectious epiduritis. Our aim was to share our surgical experience and proceed of a Literature review. Cases Presentation: Between January and August 2022, two patients male were surgically cared, aged of 42 and 60 years old. The gout was unknown in the youngest and poorly followed in the eldest. There was no past medical history of tuberculosis or immunodeficiency in both. The early diagnosis retained was unspecific lumbar spondylodiscitis due to clinical features: Patients complained both of lower back pain with initial fever. It was of a progressive left L5S1 deficit with erectile defect and dysuria in the first case and a progressive paraplegia without sphincter disorders in the second case. We proceeded with a lumbar laminectomy with a biopsy on both patients. The spinal tophus was ligamentous in one case and arthro-ligamentous in the other. There was a progressive motor recovery from postoperative Day-2 till postoperative Month-1. A probabilistic antituberculosis treatment was promptly initiated postoperatively based on radioclinic features while waiting for histologic proof. The Polymerase Chain Reaction (PCR) of Mycobacterium tuberculosis was negative and the histology was of a chronic calcified osteitis with dense fibrosis in both. The anti-gout treatment was implemented after 15 days with blood test evidence. A rheumatologic follow-up was also initiated and adjuvant physio-therapy. The results were very satisfactory from 4 - 6 months with independent walking. Discussion Conclusion: Spinal Gout may be suggested in 40-male-old faced with any acute rachialgia with neuro deficit with dubious neuro-imaging.展开更多
