The article explores the association between atopic dermatitis burden, sociodemographic index, and the utilization of biologics like dupilumab and tralokinumab across 50 countries from 2017 to 2022. It highlights disparities in biologic utilization based on countries' economic status, with high-cost barriers limiting access in low-middle and middle-SDI countries. The study suggests that measures to reduce costs and improve access to biologics, such as biosimilars, are needed to address these disparities and improve outcomes in resource-limited settings.

Background: There is limited knowledge on international trends in topical calcineurin inhibitor (TCI) utilization. Objective: To describe international TCI utilization trends from 2012 to 2019 and evaluate the relationship of country-level economic status, geographic location, and atopic dermatitis (AD) disease burden with drug utilization. Methods: We used IQVIA MIDAS ® pharmaceutical quarterly sales data to attain country-level purchasing of TCIs in grams from 2012 to 2019. A multivariable linear regression estimated the association between countries' sociodemographic index (SDI), AD disability-adjusted life year (DALY) rates, and geographic location with TCI utilization. Results: A total of 68 countries were included in our analysis. From 2012 to 2019, overall TCI utilization increased by 66% but remained 11.2 times higher in high-sociodemographic compared with low-middle/low-sociodemographic countries. SDI and geographic location were associated with greater TCI utilization in multivariable analyses, whereas AD DALY rates were not. High-SDI countries used 21,476 grams (95% confidence interval [CI]: 11,915 to 31,036) and high-middle SDI countries used 9,403 grams (95% CI: -393 to 19,200) more TCIs per 100,000 people compared with low-middle/low-SDI countries, respectively. Northern hemisphere countries used 8,588 grams more TCIs per 100,000 people (95% CI: 612 to 16,564). Conclusions: We demonstrated greater TCI utilization among high-SDI compared with lower SDI countries.

Although melanoma only accounts for 1% of skin cancers, it is responsible for most skin cancer deaths. Glioblastoma multiforme, a high-grade astrocytoma, is the most aggressive and devastating primary brain tumor. These two diseases remain to be the biggest therapeutic challenge in both specialties of dermatology and neuro-oncology. A 53-year-old Filipino male who presented with a 2-year history of generalized dark brown and black patches on the body developed weakness and numbness of the left extremities. Biopsy and immunohistochemical staining of the skin revealed nodular melanoma with adjacent regressing melanoma. Biopsy of the intracranial mass showed glioblastoma multiforme. One month after the partial excision of the intracranial mass, the patient expired due to brain herniation. Nodular melanoma and glioblastoma multiforme may occur concomitantly in a patient. A review of the literature suggests a shared genetic predisposition. Its existence carries a poor prognosis and requires early detection to start aggressive treatment., Competing Interests: All authors declared no conflicts of interest., (© 2024 Acta Medica Philippina.)
