ABSTRACT
Pruritus is a common symptom of bullous pemphigoid (BP), but has been poorly studied. The aim of this study was to analyse the characteristics of pruritus in patients with BP and its impact on their quality of life. A multicentre prospective observational study (in 15 French hospitals) was performed. A total of 60 patients were included, with a mean age of 77.4 years. Pruritus occurred daily in 85% of patients, with a mean pruritus intensity of 5.2/10. Tingling sensations were present in 72.4% of patients and burning sensations in 68.9%. Pruritus was exacerbated by stress, fatigue and xerosis. The mean ItchyQol score was 56.2/110 and the mean 5-D Itch Scale score was 16.5/25. The severity of pruritus was not related to age, sex, BP activity score, eosinophilia, or anti-BP230 and anti-BP180 autoantibodies. This study revealed that pruritus in BP is poorly tolerated and is an important cause of impaired quality of life.

OBJECTIVES: To detect subclinical entheses and nail abnormalities using gray-scale (GS) and power Doppler ultrasonography (PDUS) between patients with nail psoriasis and those with inverse and scalp psoriasis. METHODS: In this prospective monocentric study, patients with nail, inverse and scalp psoriasis, without psoriatic arthritis or systemic treatment, were included. Clinical evaluation and ultrasonographic assessment of 14 entheses and 12 nails were done by a dermatologist (clinical assessment) and a rheumatologist (ultrasonographic assessment). RESULTS: 518 entheses were analyzed, with no statistical difference between the two groups when considering GS enthesopathy (P=0.66). PDUS signal of the entheses were low (<1%) in both groups. Matrix thickness was significantly higher in patients with nail disease (1.94mm vs. 1.77mm; P=0.007). PDUS of the skin thickness at the level of distal joint and the loss of the trilaminar appearance were also significantly associated with nail psoriasis (P=0.037 and P<0.0001 respectively). CONCLUSION: Detection of subclinical US enthesopathy is not so rare in both groups, unlike PD signal, but with no statistical difference. US are a good tool to evaluate the different components of psoriatic nails (loss of trilaminar appearance, nail thickening and inflammation of the skin thickness) which are significantly associated with nail psoriasis.
