The advent of biologics has greatly improved patient outcomes, yet some patients are compelled to switch therapies. Predicting these therapeutic failures is important; however, the factors associated with switching biologics have not been fully explored. This study examined patterns and determinants of biologics switching in psoriasis treatment retrospectively over 13 years. We focused on the association between clinical characteristics, basal laboratory data, and frequency of biologics switching. The findings revealed that elevated Psoriasis Area Severity Index scores and the presence of arthritis were observed in patients who experienced two or more treatment switches compared with those without treatment switches. Moreover, neutrophil to lymphocyte ratio was associated with higher biologics switching rates, indicating that systemic inflammation significantly impacts treatment adherence. A treatment approach, taking into account both the clinical presentation and inflammatory biomarkers, may be important for optimizing patient management in psoriasis.

Familial progressive hyperpigmentation with or without hypopigmentation (FPHH) is an autosomal dominant disorder characterized by widespread skin hyperpigmentation, café‐au‐lait spots, and hypopigmented circular macules, resulting from KITLG variants. KITLG, expressed by keratinocytes, binds to KIT on melanocytes, stimulating melanogenesis. Disturbances in the KITLG‐KIT interaction result in diffuse hyperpigmentation in FPHH. However, the mechanisms behind hypopigmented macule formation remain unclear. This report presents a unique FPHH case in a patient with a novel KITLG mutation (Ser78Leu). Notably, the patient showed multiple hypopigmented macules and striae along the lines of Blaschko. Digital polymerase chain reaction analysis of the DNA from skin and blood tissues indicated a copy‐neutral loss of heterozygosity at the KITLG locus, only in the hypopigmented macule. These findings suggest that the hypopigmented macules might result from revertant mosaicism. Conversely, café‐au‐lait spots do not follow the lines of Blaschko and can superimpose on the hypopigmented striae, indicating a distinct pathogenesis. This case contributes to the understanding of the genetic mechanisms in FPHH.

We aimed to analyze the clinical profile and malignancy indicators in dermatomyositis (DM) with anti‐transcriptional intermediary factor 1 antibody (anti‐TIF1γ‐Ab). A comparison was made between clinical information of anti‐TIF1γ DM patients with and without malignancy. Additionally, a review of the literature on anti‐TIF1γ DM and malignancy was conducted by searching PubMed and EMBASE databases. In our cohort of 37 patients, 27.0% (10/37) developed malignancy. The timeframe during which these 10 patients developed malignancy ranged from 21 months prior to the diagnosis of DM to 36 months following the diagnosis of DM. Specifically, one patient was diagnosed with breast cancer at the age of 36. Comparing the groups with and without malignancy, we found that age over 65 years (40% vs 7.4%, P = 0.035), a shorter duration from the onset of symptoms to the diagnosis of DM (2.5 vs 10 months, P = 0.003), and higher erythrocyte sedimentation rate (ESR) levels (23 vs 10 mm/h, P = 0.048) were found to be associated with an increased risk of malignancy. Conversely, the presence of Gottron's papules (63% vs 20%, P = 0.029) may suggest a lower likelihood of malignancy. The literature review revealed that the prevalence of myositis‐associated malignancy was 40.7% (340/836), with variations ranging from 19% to 82.9% across different series. In summary, factors such as age over 65 years, a shorter duration between symptom onset and diagnosis of DM, and elevated ESR levels may indicate an increased risk of malignancy in anti‐TIF1γ DM patients.

Hereditary angioedema (HAE) symptoms can vary greatly. Disease burden evaluation is essential for providing adequate treatments for patients. Patient‐reported outcome measures (PROMs), including the 12‐Item Short Form Health Survey (SF‐12), the Angioedema Quality of Life (AE‐QoL), the Hospital Anxiety and Depression Scale (HADS), and the Work Productivity and Activity Impairment: Specific Health Problem (WPAI:SHP) questionnaires, were collected in 2021, before modern medications for long‐term prophylaxis (LTP) of HAE were licensed in Japan. Patients also reported their HAE attack frequency as “annual” (several attacks annually), “monthly” (several attacks monthly) or “weekly” (several attacks weekly). Multiple linear regression analyses were conducted on the relationship between independent parameters (sex, age, attack frequency, HAE type, and HADS scores) and dependent parameters (AE‐QoL and SF‐12 scores). Fifty‐four patients reported PROMs. All PROMs showed substantial health‐related quality of life (HRQoL) impairment. Overall, the higher the attack frequencies, the greater the reported impairment in the PROMs tended to be. In multiple linear regression analyses, higher AE‐QoL Fatigue/Mood and Fears/Shame domain scores (greater impairment) were associated with higher HADS anxiety subscale scores; higher AE‐QoL total scores (greater HRQoL impairment) and lower SF‐12 Physical and Mental Health Composite scores (greater general health impairment) were associated with higher HADS depression subscale scores. Patients with monthly or weekly HAE attacks reported numerically low absenteeism and numerically high presenteeism and work productivity loss as measured by the WPAI:SHP questionnaire. In this study, conducted before modern LTP options were available in Japan, patients with HAE reported notable impairment in HRQoL and work productivity. Weekly or monthly HAE attack frequencies were associated with a high disease burden. Furthermore, a substantial number of patients reported notable fatigue/mood impairment as measured by the AE‐QoL and depression as measured by the HADS regardless of attack frequency. These results provide a basis for future studies evaluating the effect of LTP on the clinical manifestations and HRQoL in patients with HAE.

We investigated the clinical efficacy of short‐term, oral fosravuconazole (F‐RVCZ) therapy for tinea pedis, commonly known as athlete's foot. F‐RVCZ (equivalent to 100 mg ravuconazole) was administered orally once daily for 1 week for interdigital and vesicular tinea pedis and for 4 weeks for hyperkeratotic tinea pedis. Efficacy was evaluated based on mycological efficacy and clinical symptoms at Weeks 1, 4, and 8 for interdigital and vesicular tinea pedis and at Weeks 4, 8, and 12 for hyperkeratotic tinea pedis. Efficacy was confirmed at the end of treatment. Therapeutic efficacy increased over time from the end of treatment for both types of tinea pedis. All adverse drug reactions (ADRs) were within expectations and there were no cases of discontinuation due to ADRs or serious ADRs. Short‐term oral F‐RVCZ therapy is expected to be as effective or more effective than terbinafine and itraconazole, which have already been approved in Japan and may be a useful option for the treatment of tinea pedis.

Observational studies have suggested an associations between hidradenitis suppurativa (HS) and metabolic syndrome (MetS) and its components. However, it remains unclear whether the relationship is causal or not. Our study aimed to investigate the causal association of HS with MetS and its components. We performed a bidirectional, two-sample Mendelian randomization study using summary-level data from the most comprehensive genome-wide association studies of HS (n = 362 071), MetS (n = 291 107), waist circumference (n = 462 166), hypertension (n = 463 010) fasting blood glucose (FBG, n = 200 622), triglycerides (n = 441 016), and high-density lipoprotein cholesterol (HDL-C, n = 403 943). Genetic instrumental variables were constructed by identifying single nucleotide polymorphisms associated with the corresponding factors. The random-effects inverse-variance weighted method was applied as the primary method. The results showed that genetically predicted HS was positively associated with waist circumference risk in both directions. High waist circumference increased the risk of HS (odds ratio [OR] 4.147; 95% confidence interval [CI] 2.610-6.590; p = 1.746 × 10-9). In addition, HS was also affected by waist circumference (OR 1.009; 95% CI 1.006-1.012; p = 3.08 × 10-7). No causal relationships were found between HS and MetS or its components other than waist circumference. The findings highlight the importance of early intervention for obesity in HS patients. Further studies are needed to determine the pathophysiology of HS associated with MetS and its components.
