Single-center survey of incidental imaging findings on computed tomography in patients with psoriasis on biologic therapy.

Psoriasis is an immune-mediated chronic inflammatory disease that predominantly affects the skin and joints. Systemic therapies are required for patients with moderate-to-severe psoriasis, and biologics can provide significant symptomatic improvement. Computed tomography (CT) analysis is recommended before and after biologic therapy to exclude the possibility of comorbid infections and malignancies; incidental findings are often detected in asymptomatic patients.

Four-year drug survival of apremilast in patients with psoriasis.

This real-world study at a single academic center retrospectively examined the drug survival of apremilast for patients with psoriasis. Retrospective information was extracted from the medical records of patients with psoriasis treated with apremilast at the Department of Dermatology, Jichi Medical University Hospital, between March 1, 2017, and June 31, 2021. In total, 281 patients were included in this study.

Proactive versus Rank-Down Topical Corticosteroid Therapy for Maintenance of Remission in Pediatric Atopic Dermatitis: A Randomized, Open-Label, Active-Controlled, Parallel-Group Study (Anticipate Study).

Topical corticosteroids are used as first-line treatment for atopic dermatitis (AD). Regarding the maintenance of remission achieved by topical corticosteroids, no previous studies have compared proactive therapy with rank-down therapy. We compared their efficacy and safety in Japanese children with moderate to severe AD.

STAT3 Activation in Psoriasis and Cancers.

Activation of signal transducer and activator of transcription (STAT)3 has been reported in many cancers. It is also well known that STAT3 is activated in skin lesions of psoriasis, a chronic skin disease. In this study, to ascertain whether patients with psoriasis have a predisposition to STAT3 activation, we examined phosphorylated STAT3 in cancer cells of psoriasis patients via immunohistochemistry.

Characterization of acne patients carrying clindamycin-resistant Cutibacterium acnes: A Japanese multicenter study.

Use of antimicrobials for acne treatment is correlated with an increased occurrence of antimicrobial-resistant Cutibacterium acnes. To clarify the role of antimicrobial use on the resistance and to investigate the characteristics of resistant strains, we conducted a multicenter study in dermatological clinics frequently visited by new patients with acne vulgaris. We collected specimens in 264 acne patients and tested 164 C.

Drug survival of biologic agents for psoriatic patients in a real-world setting in Japan.

This is a Japanese retrospective single-center study carried out between 1 January 2010 and 21 November 2018 at the Department of Dermatology in Jichi Medical University Hospital. The drug survival rate for six biologic agents used for the treatment of psoriasis was investigated. We reviewed the clinical records of 315 treatment series of 205 patients with moderate to severe psoriasis treated with adalimumab (103 cases), infliximab (70 cases), ustekinumab (66 cases), secukinumab (38 cases), brodalumab (12 cases) and ixekizumab (26 cases).

Risk Factors for the Development of Psoriasis.

Psoriasis is an immune-mediated genetic skin disease. The underlying pathomechanisms involve complex interaction between the innate and adaptive immune system. T cells interact with dendritic cells, macrophages, and keratinocytes, which can be mediated by their secreted cytokines.

Drug survival of apremilast in a real-world setting.

Apremilast is a novel oral phosphodiesterase-4 inhibitor approved for treatment of plaque psoriasis and psoriatic arthritis in Japan in December 2016. We have treated a substantial number of patients with psoriasis with apremilast and investigated the length of the treatment period with apremilast (drug survival of apremilast) in 138 patients with psoriasis who were treated at the Department of Dermatology in Jichi Medical University Hospital from 1 March 2017 to 31 August 2018 using the Kaplan-Meier survival curve. The drug survival rate of apremilast at 1 year was 53.

Results of a retrospective study on the efficacy and safety of adalimumab 80 mg administrated every other week in patients with psoriasis at a single Japanese institution.

Adalimumab (ADA) is one of the tumor necrosis factor (TNF)-α monoclonal antibodies used for the treatment of psoriasis. In Japan, standard dosing of ADA for adults is an initial s.c.

Real-world use of apremilast for patients with psoriasis in Japan.

Apremilast is a novel oral phosphodiesterase 4 inhibitor effective for psoriasis. It regulates the production of pro-inflammatory mediators. Apremilast was approved in December 2016 in Japan; however, its efficacy and safety in a real-world setting among Japanese patients have not been reported.

Effects of maxacalcitol ointment on skin lesions in patients with psoriasis receiving treatment with adalimumab.

Adalimumab is a biologic that is very effective for treatment of psoriasis. However, recalcitrant or recurrent lesions sometimes occur during treatment. Maxacalcitol is an active vitamin D3 ointment that is effective in treatment of psoriasis.

Long-term continuous versus intermittent cyclosporin: therapy for psoriasis.

A multicenter randomized controlled study was conducted to assess the long-term efficacy and safety of cyclosporin A therapy for psoriasis using either a continuous or an intermittent regimen. Initially, both regimens consisted of 3-5 mg/kg/day administration of CyA. Once remission was obtained, CyA dose was maintained between 0.
