ABSTRACT

OBJECTIVES: The aims of this study in SLE population were (1) to describe ultrasonography (US) joint abnormalities, (2) to estimate the reliability of clinical swollen joint count (C-SJC) and SLEDAI (C-SLEDAI) versus US-SJC and US-SLEDAI scores, (3) to highlight specific patterns of lupus patients with Power Doppler (PD) abnormalities. METHOD: For this cross-sectional multicenter study, 151 consecutive adult SLE patients were recruited. Evaluation included a clinical standardized joint assessment, B-mode and PD US of 40 joints and 26 tendons blinded for clinical examination. Reliability and agreement between clinical and B-mode US were calculated using the intraclass correlation coefficients (ICC [95% Confidence Interval]). RESULTS: We found a very high frequency of subclinical US abnormalities in asymptomatic patients: 85% of patients without joint symptoms had at least 1 US abnormality. Among them 46 patients (87%) had a history of joint involvement. The most frequent abnormalities were joint effusmaions (108 patients), synovial hypertrophy (SH, 109 patients) and synovitis (61 patients). Joint or tendon PD signal (grade>1) was found in 44% of patients (67/151). Synovitis were mainly located especially on MCPs and wrists. Even if reliability between clinical and grey-scale US SJC assessments was poor, reliability between clinical and US SLEDAI was good. Comparison between SLE patients with and without PD signal did not show any specific SLE pattern. CONCLUSION: US may be useful to assess joint involvement in SLE patients but did not significantly change SLEDAI score.

ABSTRACT

Cauda equina syndrome is an uncommon complication of ankylosing spondylitis (AS) characterized by the slow and insidious development of severe neurologic impairment. Imaging studies usually show a wide lumbar canal with dural ectasia. No medical or surgical treatment has been proven effective. We managed the care of a 66-year-old man who had longstanding AS and clinical features of cauda equina syndrome, including anal incontinence and buttock hypoesthesia. Magnetic resonance imaging demonstrated no cause for these symptoms other than AS. The patient was treated with infliximab, a monoclonal antibody to tumor necrosis factor alpha that is used for the treatment of active AS. After 3 infliximab infusions, sphincter control and sensation were normal. The treatment was continued, and he was still doing well 1 year later. This is the first report of an effective treatment for cauda equina syndrome complicating AS. Our case report strongly supports an inflammatory mechanism to this condition.
