[Sudden deafness and acute synovitis: a case report].

A case of sudden deafness followed by arthritic manifestations is reported. The importance of immunologic tests, such as circulating immune complexes and the HLA system, in making a correct diagnosis is emphasized, which in turn suggests the possibility of establishing new diagnostic strategies.

Clinical, laboratory and immunogenetic aspects of arthritis associated with chronic lymphocytic thyroiditis.

OBJECTIVE: Synovial fluid effusions and/or arthritis may be found in patients with chronic lymphocytic thyroiditis (CLT), even in the absence of hypothyroidism. Sometimes these arthropathies can be attributed to the rheumatic diseases frequently associated with CLT, but in some instances the arthritis seems to be independent of any of the diseases known to cause arthritis, and therefore remains unclassified. This study was carried out in an attempt to characterize the type and outcome of arthritis associated with CLT. METHODS: We performed a prospective study with a follow-up of 6.42 years (range 4-13) on 33 patients affected with CLT and presenting with arthritis. All conditions known to cause arthritis were previously excluded. Investigations included HLA typing, x-ray of the affected joints and, when possible, synovial fluid (SF) analysis with an interleukin (IL)-1 beta determination. Patients were divided based on their clinical presentation into two groups: those with polyarthritis and those with oligoarthritis. RESULTS: During the follow-up, 8 out of 16 patients with polyarthritis developed severe rheumatoid arthritis, characterized by bone erosions, high levels of SF IL-1 beta and an increased frequency of HLA DR4. The other 8 patients had polyarthritis in a mild, non-erosive form, which responded well to symptomatic drugs. Oligoarthritis, found in 17 patients, also showed a mild evolution, with frequent spontaneous remissions. The non-rheumatoid polyarthritis and oligoarthritis patients were characterised by the absence of bone erosions, low levels of SF IL-1 beta and an increased frequency of HLA DR3. CONCLUSIONS: We conclude that it is possible to find in association with CLT a type of inflammatory arthritis characterized by a mild, non-erosive evolution, low SF levels of IL-1 beta and an increased frequency of HLA-DR3. This arthritis seems to be independent of thyroid dysfunction and shows a clinical pattern similar to the arthritis usually found in connective tissue diseases.

Clinical, laboratory and immunogenetic aspects of post-traumatic psoriatic arthritis: a study of 25 patients.

OBJECTIVE: In a previous study we demonstrated that the prevalence of trauma preceding arthritis was higher in patients with psoriatic arthritis (PsA) than in patients with rheumatoid arthritis (RA) or ankylosing spondylitis (AS); of 300 consecutive patients with PsA, 25 (8%) had a history of trauma before (< 3 months) the onset of the disease. The present study was carried out to characterize the clinical, laboratory and immunogenetic profiles of post-traumatic (PT)-PsA. PATIENTS AND METHODS: The clinical and laboratory features of 25 patients with PT-PsA were studied at onset (first 6 months) and after a follow-up period of 1-7 years, and were compared with those of 275 PsA patients without any history of trauma (nonPT-PsA). HLA typing was performed in PT-PsA patients, and synovial fluid (SF) analysis, including interleukin (IL)-1 and IL-6 determinations, was carried out in 12 subjects with PT-PsA and in 32 with nonPT-PsA. RESULTS: No differences were observed between PT-PsA and nonPT-PsA patients with regard to their clinical evolution. ESR (p < 0.0001) and CRP (p = 0.005) were higher in PT-PsA than in nonPT-PsA patients at disease onset but not after follow-up. No differences were found in the other blood indices. SF analysis revealed higher IL-6 levels in PT-PsA than in nonPT-PsA patients (p < 0.0005). CONCLUSION: Our study demonstrates that the prevalence of trauma preceding arthritis is higher in PsA than in RA or AS. Clinical and laboratory findings in patients with PT-PsA differed from those with nonPT-PsA only at disease onset (first six months), however, showing an abrupt clinical presentation and a more acute phase response. This pattern may be related to the higher levels of IL-6 found in the SF of PT-PsA than in nonPT-PsA patients. However, during the follow-up period the two groups became indistinguishable, and no difference was observed between PT-PsA and nonPT-PsA regarding the evolution of the disease.
