Reliability assessment and validation of the post-acne hyperpigmentation index (PAHPI) in a population from Sub-Saharan Africa in Senegal

An Assessment of Current Clinician- and Patient-Reported Outcome Measures for Acne Scarring and Dyspigmentation: A Scoping Review

Acne-associated scarring and dyspigmentation (ie, erythema, hyperpigmentation) are common sequelae with significant psychosocial impact, but little is known about what measures are most often used to assess these outcomes. This scoping review evaluates the use of current patient-reported outcome measures (PROMs) and clinician-reported outcome measures (ClinROMs) for acne scars and dyspigmentation. For scars, 7 PROMs and 18 ClinROMs were used, with most being unvalidated. Similarly, for dyspigmentation, 4 PROMs and 8 ClinROMs were identified, but no validated PROMs were identified. These results highlight reliance on unvalidated measures in research and clinical trials and suggest the need for developing high-quality validated measures, particularly PROMs, to improve research quality and develop better treatments.

Support for dermatological research in Sub-Saharan Africa: insights from African hair and skin research programs

BACKGROUND

The structure and physiology of skin and hair in people of African ancestry are different from other ethnic categories and studies from other continents cannot necessarily be extrapolated to Sub-Saharan Africa (SSA) due to the differences in genetics, lifestyle, climate, cultures, and hair and skin care practices. The aim of this report is to highlight the recent advances in local skin and hair research in SSA from a grant program.

METHODS

African Hair and Skin Research Grants from an industrial sponsor were awarded between 2013 and 2022 on five main topics: acne, hair and scalp, keloid scars, atopic dermatitis, and air pollution. A literature search in Scopus identified publications on these topics in African or black skin in SSA and worldwide to provide insight into the impact of the program.

RESULTS

The number of publications from around the world on the skin and hair of people of African ancestry has increased significantly over the past 30 years on all five topics, especially as a result studies conducted in the United States. Fewer studies have been conducted in SSA but there has been an increasing number of publications over the past 10 years, especially from South Africa.

CONCLUSIONS

Scientific and clinical partnerships between the industry, academia, and public healthcare sectors have contributed to a steady increase in hair and skin publications from SSA, which may be useful for the development of tailored products and public educational campaigns to raise awareness of the risks of using inappropriate products.
