Immune response to SARS-CoV-2 mRNA vaccine in patients with psoriasis treated with biologics.

The effect of psoriasis treatment with biologics on the efficacy of COVID-19 vaccines is largely unknown. Our study aimed to evaluate antibody response against SARS-CoV-2 following two doses of BNT162b2 (Pfizer/BioNTech vaccine) in patients with psoriasis receiving biologic monotherapy, and compare it with that of healthy controls.

Polymorphism in Gene for ABCC2 Transporter Predicts Methotrexate Drug Survival in Patients with Psoriasis.

: Methotrexate is widely prescribed for the treatment of moderate-to-severe psoriasis. As drug survival encompasses efficacy, safety, and treatment satisfaction, such studies provide insights into successful drug treatments in the real-life scenario. The objective was to define methotrexate drug survival and reasons for discontinuation, along with factors associated with drug survival, in a cohort of adult patients with moderate-to-severe plaque psoriasis.

Apremilast monotherapy for palmoplantar pustulosis: Report of three cases.

Palmoplantar pustulosis or palmoplantar pustular psoriasis is chronic skin conditions, characterised by eruptions of sterile pustules on an erythematosquamous background. High-quality data on the treatment of palmoplantar pustulosis are limited, and none is accepted as being effective in general. Apremilast is a small molecule inhibitor of phosphodiesterase 4 approved for the treatment of plaque psoriasis and psoriatic arthritis.

Polymorphisms in GNMT and DNMT3b are associated with methotrexate treatment outcome in plaque psoriasis.

Methotrexate is used as first-line treatment of moderate to severe psoriasis. Despite the marked variability in treatment outcomes, no pharmacogenetic markers are currently used for personalised management of therapy. In this retrospective study, we investigated the effects of genetic predisposition on efficacy and toxicity of low-dose methotrexate in a cohort of 137 patients with moderate to severe plaque psoriasis.

Drug survival of biological therapy is showing class effect: updated results from Slovenian National Registry of psoriasis.

Background: Drug survival is an important measure of successful treatment of patients with chronic diseases such as psoriasis. Therefore, the objective was to calculate drug survival and examine safety profile of biologics and immunomodulators (adalimumab, apremilast, etanercept, ixekizumab, infliximab, secukinumab, and ustekinumab) from the Slovenian National Registry of patients with moderate-to-severe psoriasis.

Methods: Data about the patients with moderate-to-severe plaque psoriasis treated with biologics were collected from 2005 until July 2018.

Drug survival of biologic therapies for the treatment of psoriasis: Results of Slovenian national registry.

The study was designed as observational retrospective analysis of the data from Slovenian Registry of patients with moderate and severe psoriasis treated with adalimumab, etanercept, infliximab or ustekinumab from 2005 to 2015. The survival rates of biologics were compared using survival analysis, and predictors of discontinuation were evaluated using a Cox regression model. All biologics have been prescribed as a first line therapy for moderate or severe psoriasis; 650 (94.

Primary systemic amyloidosis with skin and cardiac involvement: a case report.

Primary systemic amyloidosis is characterized by the deposition of insoluble monoclonal immunoglobulin light chains in various tissues and is usually associated with an underlying plasma cell dyscrasia. In the early stage of the disease, dermatological findings can be the only manifestation, as opposed to organ involvement in the later stages. A dermatologist can diagnose amyloidosis early with a skin biopsy stained with Congo red dye and other appropriate investigations.

Congenital longitudinal melanonychia: a case report.

Congenital longitudinal melanonychia is rarely seen in Caucasians and poses a diagnostic dilemma. It is characterized by the presence of hyperpigmented brown or black streaks visible in the nail plate. We present the case of 20-month-old boy with congenital longitudinal melanonychia, the diagnostic procedure, and management.

Sporotrichoid presentation of Mycobacterium marinum infection of the upper extremity. A case report.

Background: Mycobacterium marinum is a human opportunistic pathogen that is known to inhabit swimming pools, home aquariums, and natural bodies of salt and fresh water. Epidemic cases involving swimming pools are easily recognized, but sporadic cases are frequently misdiagnosed.

Objective: A 42-year-old male presented with a 2-month history of the appearance of livid, verrucous, painless nodules on his right upper extremity.

Computer-aided measurement of psoriatic lesion area in a multicenter clinical trial--comparison to physician's estimations.

Background: There is a great need for accurate and informative outcome measures in clinical trials. In psoriasis, therapeutic effect is usually assessed by physician's estimation of psoriatic area and other signs. These measures were found to be un-reproducible.

Idiopathic eruptive macular pigmentation.

We present the case of a 10-year-old girl with a six months history of disseminated asymptomatic, brown pigmented macules on the trunk and proximal parts of the extremities. The clinical picture, histological findings, and the course of disease were similar to those of idiopathic eruptive macular pigmentation. The cutaneous lesions gradually disappeared over the next two years without any treatment, and no relapse occurred.

Grover's disease: successful treatment with acitretin and calcipotriol.

A 74-year-old man presented with a five-month history of highly pruritic keratotic papules on the trunk and extremities. Laboratory data revealed mild eosinophilia, elevated IgE (483KE/I) and no other signs of atopy. Tests to exclude parasitic infestation were negative.
