Abstract:

OBJECTIVE: The objectives of this study were to determine the musculoskeletal (MSK) conditions associated with pediatric psoriasis (Pso) and to evaluate the thickness of Achilles tendon of children with Pso and healthy controls (HCs). METHODS: Pso patients who were followed-up in dermatology outpatient clinic were referred to a pediatric rheumatology center. All patients and healthy peers were evaluated with standardized forms. Both patients and controls underwent ultrasonographic evaluation for Achilles tendon thickness. RESULTS: A total of 55 pediatric Pso and 46 healthy children were included in the study. Of patients with Pso 56.4% had arthralgia, 25.5% had lower back pain, 18.2% had heel pain, 12.7% had hip pain, and 10.9% described morning stiffness. Arthritis was detected in 7.3%, sacroiliac tenderness in 12.7%, and enthesitis in 9.1% of the patients. Arthralgia, lower back pain, and heel pain were significantly frequent in Pso group than healthy children median left and right Achilles tendon thicknesses of Pso patients who were significantly greater than that of HCs prevalence of psoriatic arthritis (PsA) among Pso patients was 7.3%. CONCLUSION: Evaluation of a child with Pso regularly for the MSK complaints is critical for the early recognition of PsA. Ultrasonography is a useful technique for screening Pso patients for early detection of enthesopaty.
