Prevalence, severity and clinical features of psoriasis in fingernails and toenails in adult patients: Italian experience
ABSTRACT Background Psoriasis is a chronic inflammatory skin disease affecting 2.0-6.5% of the European population. Although the most striking clinical features of psoriasis involve the skin, other organs including nails and joints may be affected in a substantial proportion of patients. Literature reports nail involvement in 10-56% of psoriatic patients, with common physical and social impairment. However, the precise prevalence of specific clinical features of nail psoriasis is somewhat under-reported. Objectives Our cross-sectional study aimed at describing the prevalence and the clinical features of nail involvement in adult psoriatic patients in a psoriasis referral centre in northern Italy. Methods A total of 178 (124 men, 54 women) consecutive adult patients (≥18 years old) with psoriasis were included. Psoriasis Area and Severity Index (PASI) and Nail Psoriasis Severity Index (NAPSI) scores were calculated for each patient. Relevant medical history was recorded. Results Nail involvement was present in 137 (99 men, 38 women) patients (76.9%). The most common nail abnormality was onycholysis, followed by crumbling, subungual hyperkeratosis, pitting and discoloration. Pitting and onycholysis were the most prevalent patterns observed in fingernails, whereas onycholysis and crumbling were the most frequent changes detected in toenails. The most frequently and severely affected nails were the fourth fingernail and the first toenail. The average PASI score was higher in individuals with nail involvement (12.0 vs. 8.7, P = 0.06). Nail changes were present in 85.7% of patients with psoriatic arthritis. Conclusions Our study confirms that nail involvement may be overlooked in psoriasis patients. Different psoriatic patterns in the nail affect specific digits more frequently.

ABSTRACT: Introduction and objectives Patients with psoriasis often have comorbidities, including other immune-mediated inflammatory diseases (IMIDs), and cardiovascular risk factors. In this article we describe the baseline prevalence of comorbidities—including other IMIDs—in a cohort of patients with psoriasis. Patients and methods AQUILES was a prospective observational multicenter study of 3 patient cohorts (patients with psoriasis, spondyloarthritis, or inflammatory bowel disease) undertaken to investigate the prevalence of comorbidities, including other IMIDs, in these settings. The psoriasis cohort comprised patients aged at least 18 years who were seen in hospital dermatology clinics. A predefined protocol was used to collect demographic and clinical data. Results The study enrolled 528 patients with psoriasis (60.2% men and 39.8% women). Mean age was 46.7 years; 89.8% of the participants had plaque psoriasis, and the median Psoriasis Area Severity Index score (PASI) was 3.2 (1.5-7.4). Comorbid IMIDs were present in 82 (15.5%) of the patients (CI 95%, 12.7%-18.9%). Spondyloarthritis was observed in 14% of patients (95% CI, 11.3%-17.2%), mostly in the form of psoriatic arthritis, for which the overall prevalence was 13.1% (95% CI, 10.5%-16.2%). Inflammatory bowel disease was present in 1.3% (95% CI, 0.6%-2.7%) and uveitis in .2% (95% CI, 0.1%-1.4%). Psoriatic arthritis was associated with male sex (odds ratio, 1.75 [.98-2.98]) and a disease duration of over 8 years (OR, 4.17 [1.84-9.44] vs a duration of < 4 years). In 73.1%, at least 1 cardiovascular risk factor was identified: smoking (40.5%), obesity (26.0%), dyslipidemia (24.8%), hypertension (24.3%), and diabetes mellitus (12.3%). Conclusion In patients with psoriasis the prevalence of other IMIDs was 15.5%, a level slightly higher than that found in the general population. Nearly three-quarters of these patients had at least 1 cardiovascular risk factor.Actas Dermo-Sifiliográficas 01/2014; 106(1). DOI:10.1016/j.ad.2014.06.003

ABSTRACT: A case-control study was performed to assess the serum levels of TNF-α, IL-12/23p40, and IL-17 in patients with plaque psoriasis, compare them with healthy controls, and correlate them with disease severity, as represented by Psoriasis Area Severity Index (PASI). 32 consecutively selected, untreated patients with active, chronic plaque psoriasis were recruited and compared to 32 age- and sex-matched healthy controls. Serum cytokine levels were determined by solid phase sandwich enzyme linked immunosorbent assay (R&D Systems Europe, Ltd.). The mean serum levels of TNF-α were significantly higher in psoriatic patients compared to those of controls (Mann-Whitney U test; P = 0.000). However, the median serum levels of neither IL-12/23p40 nor IL-17 differ significantly between the 2 groups (Mann-Whitney U test; P = 0.968 and P = 0.311, resp.). No significant correlations were found between PASI and any of the cytokine serum levels (Spearman's rank test; P > 0.05). Despite the well-evidenced therapeutic efficacy of biologic agents targeting TNF-α, IL-12/23p40, and IL-17, serum levels of TNF-α, IL-12/23p40, and IL-17 do not seem to correlate with the severity of psoriatic skin disease in untreated patients, as represented by PASI. Further investigation may add more data on the pathogenetic cascade of psoriasis.
