This study aimed to evaluate serum brain-derived neurotrophic factor levels, stress, and quality of life in leprosy patients, and to explore their interrelations. A cross-sectional study was conducted from September 2024 to May 2025 at 3 hospitals in Medan, Indonesia, involving 45 leprosy patients aged ≥ 18 years who met inclusion criteria. Serum brain-derived neurotrophic factor levels were measured using ELISA, stress was assessed using the Perceived Stress Scale-10, and quality of life was evaluated through the WHOQOL-BREF questionnaire. Descriptive statistics, Shapiro-Wilk normality test, and Spearman's rank correlation were used for analysis. The mean serum brain-derived neurotrophic factor level was 7.38±3.37 ng/mL. Patients with multibacillary leprosy without reaction had higher brain-derived neurotrophic factor levels than those with type 1 or type 2 reactions. Stress levels were mild in 42.22% and severe in 28.89% of patients. Quality of life scores varied widely. A strong negative correlation was found between brain-derived neurotrophic factor and stress (r=-0.953, p< 0.0001), and a strong positive correlation between brain-derived neurotrophic factor and quality of life (r=0.962, p< 0.0001). These findings suggest that serum brain-derived neurotrophic factor levels are associated with psychological well-being in leprosy patients and may serve as a potential biomarker for mental health monitoring in this population.

Psychological interventions reduce itch in patients with skin diseases. However, previous systematic reviews and meta-analyses did not include patients with non-skin-related chronic itch and did not consider excoriations as outcome. This study therefore summarized randomized controlled trials investigating effects of psychological interventions on itch, scratching, and excoriations in patients with chronic itch due to all causes. A systematic literature search was conducted. A random effects model was used to aggregate between-group effect sizes. It was found that 17 of the 20 trials included patients with atopic dermatitis. Small to large post-treatment and follow-up effects were observed on self-rated itch intensity (post-treatment: k = 12, g = -0.37 [-0.60; -0.15]; follow-up: k = 6; g = -0.59 [-0.97; -0.21]), externally rated excoriations (post-treatment: k = 6, g = -0.29 [-0.49; -0.09]; follow-up: k = 6; g = -0.34 [-0.53; -0.15]), and self-rated scratching intensity (post-treatment: k = 2, g = -0.99 [-1.35; -0.63]; follow-up: k = 2; g = -0.85 [-1.22; -0.48]). Small post-treatment effects were observed on self-rated itch frequency (k = 3, g = -0.22 [-0.40; -0.04]). Thus, psychological interventions show promise in reducing not only itch and scratching, but also excoriations, with effects lasting up to 1 year.

Organ transplant recipients (OTRs) face an elevated risk of skin cancer due to ultraviolet radiation (UVR) exposure and the need for chronic immunosuppression. Patient education is essential for early skin cancer detection and prevention. This cross-sectional study evaluated knowledge and attitudes regarding sun protection and skin cancer among 177 OTRs during their routine check-up at a specialized dermatologic outpatient clinic in a German University Hospital, using the validated Skin Cancer and Sun Knowledge (SCSK) scale. Demographic, clinical and transplant-related variables were analysed to identify factors associated with specific knowledge gaps. The mean SCSK score was 16.59 (standard deviation, SD±3.96). While most patients understood basic sun protection, key deficits were noted in their understanding of tanning risks, the meaning of sun protection factor (SPF) and symptoms of skin cancer. Heart transplant recipients (p=0.002) and those with immunosuppression >3 years (p=0.028) had significantly lower scores indicating inferior knowledge. Male sex and age <40 and >60 years were also associated with lower knowledge levels. Self-reported "well-informed" patients scored significantly higher (p=0.003). Despite specialized routine dermatologic care, knowledge gaps persist in high-risk subgroups of OTRs, highlighting the need for targeted, longitudinal education strategies in interdisciplinary transplant aftercare.
