Lichen planus is chronic inflammatory mucocutaneous disease. Involvement of nails (nail lichen planus: NLP) could be the only manifestation or it could be associated with the other typical skin and mucous localizations. Typical NLP alterations are linear nail bed dyschromia, longitudinal ridging, splitting, onycholysis, and subungual hyperkeratosis. Read More

Objectives: To evaluate the clinical characteristics, disease burden, and treatment patterns of peripheral spondyloarthritis (pSpA) patients with and without psoriasis using data from the ASAS-perSpA study.

Methods: We included 433 patients who had a diagnosis of pSpA according to the rheumatologist's diagnosis from the ASAS-PerSpA study. The presence of a personal history of psoriasis was defined as the presence of signs of psoriasis at physical examination or the presence of psoriatic nail dystrophy, including onycholysis, pitting, and hyperkeratosis, or a history of psoriasis diagnosed by a physician.

The relationship between psoriasis and onychomycosis is controversial, and the exact nature of this association remains to be clearly elucidated. In healthy nails, the compact nail plate acts as a barrier, preventing any infection. In psoriatic nails, the nail plate involvement, together with abnormalities in the blood capillaries, may lead to decreased natural defenses against microorganisms. Read More

Nail disease in psoriasis has been found to be associated with psoriatic arthritis (PsA); however, which subtype of nail disease holds greater relevance to PsA remains unclear. This study was performed to explore the associations between three subtypes of fingernail disease (pitting, onycholysis, and hyperkeratosis) and PsA among patients with psoriasis. Patients with psoriasis attending five dermatology clinics in Shanghai between January 2020 and May 2021 were examined for skin, joint, and fingernail changes. Read More

We report the case of a 39-year-old woman who presented with generalized malaise; lymphadenopathy; arthritis; dactylitis; ecchymosis; acute onycholysis; and a red, nonpruritic, nonscaly, mottled rash on the right breast 24 hours after the first injections of ixekizumab for psoriasis and psoriatic arthritis. Ixekizumab is a humanized IgG4 monoclonal antibody that binds to IL-17A. Adverse events of ixeki-zumab include infection, inflammatory bowel disease, candidiasis and tinea infections, severe injection-site reactions, arthralgia, headache, infections, neutropenia, and thrombocytopenia.

Background: Whether nail psoriasis can increase the risk of onychomycosis is still being debated, and data relating to the prevalence of onychomycosis among psoriasis patients receiving different treatments is limited.

Objectives: To investigate the overall prevalence and prevalence compared among psoriasis treatments of onychomycosis in patients with nail psoriasis and fungal involvement.

Methods: A prospective study of three groups of nail psoriasis being treated with only topical medication, methotrexate, or biologics (25 patients per group, 150 nails) was conducted at Siriraj Hospital (Bangkok, Thailand) during November 2018 to September 2020. Read More

Selective pan fibroblast growth factor receptor (FGFR) inhibitors have been linked to severe onycholysis, the uncomfortable separation of the nail plate from the nail bed. Recommendations to assist with FGFR inhibitor onycholysis vary based on the severity. We hypothesized that the application of topical lidocaine to mimic a digital nerve block would be beneficial in addition to traditional supportive care interventions and subsequently report its immediate and continued efficacy for targeted therapy-induced onycholysis.
