Psoriasis is a chronic inflammatory disease affecting up to 3% of the general population. The prevalence of nail involvement in psoriasis patients varies between 15% and 79%. While the nails represent a small portion of the body surface area, psoriasis in these areas can have a disproportionate influence on a patient’s physical and psychosocial activities. Differential diagnosis between an onychomycosis and a psoriatic nail could be challenging; nevertheless, coexistence of onychomycosis and nail psoriasis also occurs and both are common disorders in the general population. Nail psoriasis can be difficult to treat. Treatment of nail psoriasis should consider the body surface area of skin disease, psoriatic arthritis, severity of nail disease, and the impairment in the quality of life. All patients should be tested for onychomycosis before starting a therapy. This recommendation is underlined by the fact that nail psoriasis is mostly treated by immunosuppressive drugs, like steroids, methotrexate, or biologics, which may aggravate mycotic nail infections. Conventional systemic therapy, such as use of steroids, cyclosporine, methotrexate, and retinoid in the long term, can cause organ toxicities. Currently, use of apremilast and tofacitinib favors an early healing of nail psoriasis because they act directly on the pathogenic targets, distressing the inflammatory signals associated with the initiation and maintenance of the disease activity, and as with several conventional synthetic disease modifying antirheumatic drugs, they are characterized by the convenience of oral administration. The number of treatment options has increased considerably in recent years; however, given the heterogeneity of the disease, the therapy should be personalized to individual cases.
IntroductionWe present the results of real-life tests conducted in adults affected by psoriatic arthritis (PsA) with mild cutaneous involvement to evaluate the efficacy of certolizumab pegol (CZP), an anti-tumor necrosis factor-alpha agent approved in Europe for the treatment of rheumatoid arthritis and PsA.MethodsAssessments included an evaluation of the Psoriasis Area and Severity Index (PASI) and the Disease Activity Score computed on 44 joints (DAS-44) correlated to the erythrocyte sedimentation rate (ESR) (DAS44-ESR). A total of 41 patients (16 men, 25 women; mean age 59.8 ± 8 years) completed the study. Of these, 36 patients were affected by both PsA and psoriasis, and five patients were affected only by PsA. A total of 32 patients (group A) completed 3 months of treatment (W12), and 12 patients completed 6 months of treatment (W24) (group B).ResultsThe clinical efficacy of CZP was consistent on both the cutaneous and rheumatic components of the treatment. The mean PASI score decreased from 4.4 ± 4.7 at baseline (BL) to 2.3 ± 3.7 at W12 (group A), and from 5.1 ± 5.7 at BL to 0.8 ± 1.2 at W24 (group B). The DAS44-ESR decreased from 4.4 ± 0.6 at BL to a mean of 2.2 ± 0.9 at W12 (group A) and from 4.1 ± 0.6 at BL to a mean of 1.9 ± 0.5 at W24 (group B). No adverse events were reported.ConclusionOur results demonstrate that CZP can be used safely and effectively to treat both the cutaneous and joint components of PsA. However, long-term data are needed to confirm our preliminary observations.
Basal cell carcinoma is the most common skin tumour, with the majority of the cases occurring on the head and neck district, where cosmetic and functional results are crucial. It can be locally destructive if not diagnosed early and treated appropriately. Surgery is the treatment of choice for most lesions, but aggressive, recurrent, or unresectable tumours can be challenging to manage. Advanced basal cell carcinoma includes high recurrence risk subtypes, in which standard therapies demonstrate lack of efficacy. This led to a need for investigating more deeply the pathogenesis of the disease and to the discovery of the implication of the hedgehog pathway. The development of systemic inhibitors of this pathway provides new treatment options for patients with advanced disease, resulting in survival improvement. Food and Drug Administration, before, and European Medicines Agency later approved 2 Hedgehog pathway inhibitors for the treatment of advanced basal cell carcinomas, vismo-degib and sonidegib. Here, we present a review of the current English language literature trying to analyze differences in the 2 drugs as a head-to-head comparison between them has not already been documented in a randomized controlled clinical trial. Although vismodegib and sonidegib showed similar efficacy and safety profiles, in an indirect comparison scenario, sonidegib has shown slightly better outcomes in locally advanced basal cell carcinoma than vismodegib. They present different molecular structures, as they bind different residues on their targets and develop resistance for different mutations. In a future scenario, clinical trials comparing the 2 drugs are needed, as well as expanding data on discontinuation of therapy and/or consequential administration of them, with the aim to improve our clinical practise.
Actinic keratosis (AK) is a superficial squamous cell carcinoma (SCC) where chronic sun exposure playing central role in its pathogenesis. UVB causes direct damage to DNA, producing pyrimidine dimers, and suppressing the protective role of p53. The stepwise progression of AK, with increased expression of anti-apoptotic Bcl-2, favors progression to SCC. Moreover, the dermal response characterized by inflammation and mediated by prostaglandins is a critical component of tumorigenesis that promotes tumor growth, tissue invasion, angiogenesis and metastasis. Other risk factors are represented by age, gender, phototype and drugs. Areas covered: In this review, the authors document the recent developments of different therapies used to treat AK and provide their perspectives on current and future treatment strategies. Expert opinion: The usefulness of long-term treatment with piroxicam and sun filters or diclofenac targeting the inflammation phases of skin tumorigenesis favors AK's healing and provides greater control of the cancerization field. Nonsteroidal anti-inflammatory drugs can be safely used in patients who use photosensitizing drugs and, therefore, are more at risk of developing skin tumors. Immunomodulatory therapies, which require shorter treatment, are characterized by more common local side effects, and need more attention by the dermatologist in the concern of patient education, resulting essential to improve adherence and outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
