A Rare Case of New-Onset Crohn's Disease in a Patient With Chronic Palmoplantar Pustulosis.

A 44-year-old woman who had been diagnosed with palmoplantar pustulosis (PPP) at 34 years old was diagnosed with moderate Crohn's disease (CD) based on endoscopic, radiological, and pathological findings. As treatment with corticosteroids, ultraviolet, and cyclosporin had achieved partial response, PPP had been refractory in a chronic continuous state. Oral prednisolone was initially started to treat CD, but clinical remission was not achieved. Intravenous ustekinumab was subsequently started at 260 mg for clinical remission of CD. Eight weeks after starting ustekinumab, clinical remission and mucosal healing were achieved and PPP manifestations on the palms and soles were markedly improved. Ustekinumab appears to offer an effective therapeutic option for patients with PPP but has yet to be approved for this induction in Japan. CD is a rare gastrointestinal involvement in PPP patients that requires attention.

Upadacitinib Plus Intensive Granulocyte and Monocyte Adsorptive Apheresis for Ulcerative Colitis Achieved Ulcer Healing for Pyoderma Gangrenosum.

A 44-year-old woman who had been diagnosed with ulcerative colitis (UC) at 22 years old was diagnosed with severe flare-up of UC based on endoscopic findings associated with new-onset active pyoderma gangrenosum (PG) on both lower legs after she decided to discontinue UC treatment. Systemic treatment with intravenous prednisolone at 30 mg/day had achieved insufficient response to UC and PG, resulting in a diagnosis of corticosteroid-refractory UC and PG. Combination therapy with upadacitinib at 45 mg/day plus intensive granulocyte and monocyte adsorptive apheresis (GMA) was started to achieve clinical remission of UC. Ten weeks after starting this combination therapy, clinical improvement of UC was achieved with PG ulcer healing on both lower legs. A combination of upadacitinib plus intensive GMA may offer an effective therapeutic option for patients with active PG in addition to UC but has yet to be approved for induction or maintenance treatment of PG worldwide. PG is a dermatological involvement in UC patients that requires attention.

Efficacy of bath-psoralen and ultraviolet A therapy for mycosis fungoides - retrospective analysis of 62 cases.

Photochemotherapy with psoralen and ultraviolet A (PUVA) is widely used for refractory skin diseases. Bathwater delivery of 8-methoxypsoralen (8-MOPS) with subsequent UVA irradiation (bath-PUVA) or oral administration of 8-MOPS with UVA is used to treat mycosis fungoides. We retrospectively analyzed 62 patients with mycosis fungoides (8 stage IA, 30 stage IB, 5 stage IIB, 18 stage IIIA, and 1 stage IVA2) treated with bath-PUVA at the Dermatology Clinic of Nagoya City University Hospital from November 2004 to December 2013. A complete response was achieved in 37 (59.7%) patients, a partial response was achieved in 16 (25.8%), and stable disease was achieved in 6 (9.7%). Progressive disease was observed in 3 (4.8%) patients. Almost all patients in stage IA/IB achieved a complete response. Of the 5 stage IIB patients, 2 achieved a partial response, 1 achieved stable disease, and 2 had progressive disease. The serum concentrations of soluble interleukin-2 receptor and lactate dehydrogenase decreased significantly following treatment with bath-PUVA (p < 0.001). We examined the risk factors of patients whose stage progressed despite PUVA treatment. A multivariate Cox regression analysis of risk factors associated with stage progression yielded a hazard ratio of 28.5 for stage IIb. Treatment with bath-PUVA is highly effective in the early stages of mycosis fungoides, and partially effective in advanced stages.

Low incidence of hypercalcemia following combined calcipotriol hydrate/betamethasone dipropionate ointment treatment in Japanese patients with severe psoriasis vulgaris.

PURPOSE: Topical active vitamin D3 application alone or in combination with topical steroid application is widely used to treat psoriasis. In Japan, combined calcipotriol hydrate/betamethasone dipropionate ointment has been used for patients with psoriasis vulgaris since September 2014. Current evidence regarding the incidence of hypercalcemia due to the use of this combination product, however, is insufficient. We evaluated the incidence of hypercalcemia following combined calcipotriol hydrate/betamethasone dipropionate ointment in patients with severe psoriasis vulgaris. METHODS: Japanese patients (n = 22) with extensive plaque psoriasis (body surface area: 20-30%) applied the combined calcipotriol hydrate/betamethasone dipropionate ointment once daily for 8 weeks, and their serum Ca concentrations were measured periodically. RESULTS: The mean serum Ca concentration changed only marginally, from 9.04 ± 0.34 mg/dL before treatment to 9.08 ± 0.39 mg/dL after 8 weeks of treatment. None of the patients had an elevated serum Ca concentration throughout the study. No cases of hypercalcemia were reported as an adverse event. No correlation was detected between the amount of the combined calcipotriol hydrate/betamethasone dipropionate ointment applied and changes in the serum Ca concentration. CONCLUSION: The incidence of hypercalcemia due to topical application of a combined calcipotriol hydrate/betamethasone dipropionate ointment is low in Japanese patients with severe psoriasis vulgaris.

Bath-PUVA therapy improves impaired resting regulatory T cells and increases activated regulatory T cells in psoriasis.

BACKGROUND: Bath-psoralen plus ultraviolet light A (PUVA) therapy is an effective, safe, and inexpensive treatment for psoriasis. Psoriasis might be due to an unbalanced ratio of Th17 cells and regulatory T cells (Treg). The Treg functional ratio is significantly lower in patients with psoriasis compared with controls and is inversely correlated with the Psoriasis Area and Severity Index score. We previously reported that bath-PUVA therapy significantly increases the number of Treg and restores Treg function to almost normal in most patients with psoriasis. OBJECTIVES: We examined the effects of bath-PUVA therapy on three distinct Foxp3+ subsets: activated Treg (aTreg), resting Treg (rTreg), and cytokine-secreting non-suppressive T cells. METHODS: We enrolled 15 patients with psoriasis and 11 healthy controls. We examined aTreg, rTreg, and cytokine-secreting non-suppressive T cells in peripheral blood obtained from the psoriasis patients before and after every fifth bath-PUVA therapy session. RESULTS: Levels of aTreg, which are considered to have the strongest suppressive activity in patients with psoriasis, were significantly increased in the early bath-PUVA therapy sessions, and then diminished. Levels of rTreg were lower in psoriasis patients than in healthy controls, and increased during bath-PUVA therapy. CONCLUSIONS: Bath-PUVA therapy induced aTreg and rTreg concomitantly with an improvement in the psoriatic lesions, suggesting a mechanism for the effectiveness of bath-PUVA therapy for psoriasis patients.

Serum interleukin-6 levels in response to biologic treatment in patients with psoriasis.

OBJECTIVES: Psoriasis is a chronic autoimmune disease involving a complex network of cytokines such as interleukin (IL)-6. We tested the hypothesis that serum IL-6 level is a useful indicator of disease activity and predicts the treatment response to biologics in patients with psoriasis. METHODS: We analyzed 113 psoriasis patients treated with biologics (73 with infliximab [IFX], 24 with adalimumab [ADA], and 16 with ustekinumab [UST]) in our hospital. Disease severity was assessed using the Psoriasis Area and Severity Index (PASI) score, and Disease Activity Score 28 based on C-reactive protein (DAS28-CRP). RESULTS: Before treatment, serum IL-6 levels significantly correlated with PASI scores in patients with psoriasis vulgaris (r = 0.432, p = 0.001) and with DAS28-CRP in patients with psoriatic arthritis (r = 0.469, p = 0.010). Serum IL-6 levels were significantly decreased by IFX (from 4.8 to 1.5) and ADA (from 2.5 to 1.4) therapy. In psoriatic arthritis, serum IL-6 levels at the endpoint tended to be lower in patients who achieved DAS28-CRP <2.3 (European League Against Rheumatism remission criteria) than in patients who did not. CONCLUSION: Serum IL-6 level may be a useful biomarker for assessing disease activity in patients with psoriasis and for predicting responsiveness of joint symptoms to biologic treatment.
