Characteristics of Late-Onset Spondyloarthritis: Data from the Moroccan Registry of Biological Therapies in Rheumatic Diseases.

Introduction The Assessment of SpondyloArthritis International Society (ASAS) criteria for axial and peripheral spondyloarthritis (SpA) allow for the classification of patients with an age of onset of disease of less than 45 years. However, SpA can start after this age. This study aimed to assess the characteristics of late-onset SpA (SpA>45 years) in the Moroccan registry of biological therapies in rheumatic diseases (RBSMR). Methods A cross-sectional study was conducted using the baseline data of the RBSMR. The protocol for the original RBSMR study was reviewed and approved by the Ethics Committee for Biomedical Research Mohammed V University - Rabat, Faculty of Medicine and Pharmacy of Rabat (approval number for the study was 958/09/19, and the date of approval was September 11, 2019), and all patients had given their written consent. Patients who met the 2009 ASAS criteria for SpA were included. They were divided into two groups: early-onset SpA (≤ 45 years) and late-onset SpA (>45 years). Clinical, biological, radiological, and therapy data of the two groups were compared. Statistical analysis was performed using SPSS v25 software (IBM Corp. Armonk, NY). Parameters with a p-value ≤0.05 were considered significant. Results Our population consisted of 194 patients. Thirty-one patients (16%) had late-onset SpA. Comparison between patients with early-onset (≤45 years) and late-onset SpA (>45 years) revealed that late-onset SpA had a higher tender joint count (p=0.01), a higher swollen joint count (p=0.02), depression (p=0.00), fibromyalgia (p=0.001), hypercholesterolemia (p=0.01), and a lower frequency of coxitis (p=0.008). Logistic regression analysis confirmed that late-onset SpA was associated with a higher tender joint count (OR=0.93, CI 95%: 0.88-0.98), a higher swollen joint count (OR=0.92, CI 95%: 0.85-0.99), depression ( OR=0.19, CI 95%:0.04-0.38), fibromyalgia (OR=1.75, CI 95%: 1.74-17.85), and a lower frequency of coxitis ( OR=0.29, CI 95%: 0.11-0.75). Conclusion As life expectancy increases, late-onset SpA will become increasingly common. It is therefore imperative to determine its characteristics. In the RBSMR study, late-onset SpA was associated with a high number of tender and swollen joints, depression, fibromyalgia, and a lower frequency of coxitis.

Case of Secondary Syphilis with Mucocutaneous, Articular, and Pulmonary Involvement in a 74-Year-Old Moroccan Man.

BACKGROUND Syphilis is a sexually transmitted infection (STI) caused by Treponema pallidum. If untreated, primary syphilis can progress to secondary syphilis, which has a characteristic rash and diverse systemic features. This report is of a case of secondary syphilis with mucocutaneous, articular, and pulmonary involvement. CASE REPORT A 74-year-old Moroccan man presented with an 8-week history of bilateral knee pain and swelling. On examination, he had bilateral knee effusions. Articular puncture brought an inflammatory fluid with a significant presence of white blood cells. Inflammatory markers were elevated. X-rays of both knees showed bilateral osteoarthritis with intra-articular calcification in the left knee. Nonsteroidal anti-inflammatory drugs and colchicine were prescribed, but were ineffective. A closer clinical examination of the patient revealed pigmented papules on the palms, soles, oral mucosa, trunk, and genitals. Treponema pallidum hemagglutination assay and Venereal Disease Research Laboratory results were positive in the blood (titers 1: 32) and joint fluid. A computed tomography scan of the chest revealed a focal opacity in the lateral basal segment of the right lung. The diagnosis of secondary syphilis with mucocutaneous, articular, and pulmonary involvement was made. The evolution was favorable after a single intramuscular injection of benzathine-penicillin. CONCLUSIONS Arthritis, mucocutaneous involvement, and lung lesions can be manifestations of secondary syphilis. A detailed anamnesis, clinical examination, serology, and imaging techniques are the pillars of diagnosing this condition.

An Abdominal Aortic Pseudoaneurysm Revealing Behçet's Disease.

Behçet's disease (BD) is a vasculitis with multisystemic manifestations. Articular involvement is frequent and benign whereas vascular complications are rare but serious and can form the onset of the disease. The assessment of the thickness of the common femoral vein wall is a new tool for the diagnosis of BD with good sensitivity and specificity. We report the case of a 52-year-old man diagnosed with BD revealed by an abdominal aortic pseudoaneurysm and a chronic monoarthritis. The first flare-up of BD can occur in men over 50 years of age. In a context of a multisystemic disease, lumbar pain should lead to the search of abdominal aortic aneurysm. The assessment of the thickness of the common femoral vein wall is accessible and should be used especially in challenging cases.
