Generalized pustular psoriasis (GPP) is a rare and severe subtype of psoriasis. Because of its rarity, GPP studies with a large sample size have been scarce. We studied the characteristics of GPP and pustular psoriasis using data from the West Japan Psoriasis Registry that had been registered until the end of December 2020. The dataset included 104 patients with pustular psoriasis and 1290 patients with other subtypes of psoriasis. Multivariate analysis revealed a significantly greater number of female patients, a significantly lower mean body mass index, and a significantly lower ratio of habitual drinkers in pustular psoriasis, compared to other subtypes of psoriasis. Of the 104 patients, 102 had GPP, including 88 von Zumbusch, 10 juvenile‐onset, and four annular pustular psoriasis. Although the male : female ratio of GPP with psoriasis vulgaris (GPP+PsV) (47/20) was similar to that of psoriasis in Japan, the GPP without PsV (GPP−PsV) group highlighted a female predominance (13/22). The mean age at GPP onset was 45.3 years, and the mean interval from PsV onset to GPP onset was 12.5 years. Four of nine patients with GPP had an IL36RN gene mutation. Infection, medicine, and pregnancy were the precipitating factors for GPP. A family history of psoriasis was present in eight (7.8%) patients with GPP. Twenty‐four patients with GPP had psoriatic arthritis. Biologics were used in 76.5% of patients with GPP, followed by etretinate (37.3%), cyclosporine (24.5%), methotrexate (13.7%), apremilast (8.8%), and granulocyte and monocyte adsorption apheresis (6.9%). Etretinate was used in 17 (51.5%) of 33 patients with GPP with less than 10‐year history. Thus, etretinate remains a good treatment option for GPP even in the era of biologics. Hypertension was the most commonly identified comorbidity, followed by diabetes. We believe that the characteristics revealed in this study can further contribute to effective GPP management.
Apremilast is safe and effective in Japanese patients with psoriasis. Higher occurrence of loose stools/diarrhea was noted in our cohort than that reported in Western real-world studies on apremilast.
We evaluated the efficacy and safety of interleukin (IL)‐17 inhibitors (IL‐17i) by analyzing 66 patients with psoriasis treated with secukinumab (n = 25), ixekizumab (n = 17) and brodalumab (n = 24) at Kurume University Hospital between December 2014 and June 2019. The mean Psoriasis Area and Severity Index (PASI) scores at baseline were 12.9, 13.4 and 9.9 in the secukinumab, ixekizumab and brodalumab groups (SECg, IXEg and BROg), respectively. At the 6‐month evaluation, the mean PASI scores were 1.7, 1.1 and 0.5 in SECg, IXEg and BROg, respectively. The proportion of patients achieving PASI of 3.0 or less was significantly lower in SECg. Drug survivals showed no significant difference among the groups. Although one patient in IXEg died due to an unknown cause, no serious IL‐17i‐associated adverse event was observed. This study showed high efficacy and relatively low risk of the treatment with IL‐17i.
IntroductionLaparoscopic surgery is a minimally invasive approach with good treatment outcomes and is currently the standard surgery for colorectal cancer in Japan. Mesenteric closure is considered unnecessary in laparoscopic colorectal surgery because it can damage the bowel and blood vessels. However, an internal hernia may develop if the mesentery is not repaired.Case presentationWe report a case of internal hernia in a 61-year-old male of Japanese ethnicity. The patient had advanced sigmoid colon cancer, early-stage transverse colon cancer, and multiple adenomatous polyposis, and underwent laparoscopically-assisted subtotal colectomy. Bowel obstruction developed six days postoperatively and did not improve with conservative treatment. Abdominal computed tomography detected an internal hernia, prompting emergency surgery in which the ileum protruding into the mesenteric defect and an anastomotic stricture were detected. Reanastomosis, mesentery closure, and ileostomy were performed after hernia repair.ConclusionIn this case, open surgery was necessary due to bowel obstruction after laparoscopic colectomy. This outcome indicated that mesenteric closure should have been performed. Thus, the benefits of mesenteric closure require assessment in future cases.
