Clinical trials of biologics have frequently excluded elderly patients, resulting in inadequate data on their safety and efficacy. Additionally, evidence of their safety and efficacy remains limited, despite some real-world studies. To assess the safety and efficacy of biologics in elderly patients with psoriasis, we compared these outcomes in younger patients using data from the West Japan Psoriasis Registry (WJPR). The WJPR consists of approximately 30 facilities in Western Japan, including various healthcare settings. This study enrolled 1395 patients who participated in the 2022 follow-up survey of the WJPR and were either using or had used biologics during the survey. These included 456 patients in the elderly group (≥65 years) and 939 patients in the younger group (<65 years). Treatment-ending adverse events (TEAEs) occurred in 15.8% and 11.3% of elderly and younger patients, respectively. The incidence rate per 1000 patient-years (PY) for TEAEs was significantly higher in elderly patients than in younger patients (32.9 vs 23.2, p = 0.0234). Infectious diseases were more prevalent in the elderly group than the younger group; however, no significant difference in the frequency of infectious diseases was found between the two groups (p = 0.0807). Malignant neoplasms occurred significantly more frequently in the elderly group than in the younger group (p = 0.0169). Our results indicate a few concerns about infection when prescribing biologics to elderly patients. Biologics were effective for both elderly and younger patients. We found no significant differences in the proportion of patients with a body surface area score ≤3%, Physician's Global Assessment score 0/1, or Patient's Global Assessment score 0/1, as well as in the mean Dermatology Life Quality Index and the Itch Numerical Rating Scale between the younger and the elderly groups. Overall, our results confirm the appropriateness of using biologics in elderly patients with regard to safety and efficacy.

Psoriatic arthritis (PsA) is characterized by multi-joint involvement, primarily affecting the small joints in the hands and feet. However, the specific pattern of joint involvement at an individual level remains uncertain. This study aimed to elucidate the pattern of joint involvement in a PsA cohort. Patients diagnosed with PsA were recruited for this cross-sectional study. Demographic, clinical, laboratory, personal and family history, and comorbidity data were collected. Descriptive statistical analysis was performed, and univariate and multivariate regression models were used to examine baseline factors influencing joint involvement. A total of 264 PsA patients (156 males) were included in the study. The results revealed a predominant involvement of peripheral facet joints. The second proximal interphalangeal joint (PIP) of the right hand exhibited the highest prevalence of swelling (18.9%), while the right knee joint had the highest prevalence of tenderness (24.2%). Older age and earlier onset of PsA were identified as independent factors associated with the swelling of the second PIP of the right hand. Older age, earlier onset of PsA, lower Psoriasis Area and Severity Index and higher Dermatology Life Quality Index scores were identified as independent factors associated with the tenderness of the right knee joint. In conclusion, the most commonly affected joints in PsA are the second PIP of the right hand and the right knee joint.
