Prevalence of Hidradenitis Suppurativa among Healthy Adults in Abuja, Nigeria.

UNLABELLED: <p>

Introduction

Hidradenitis suppurativa (HS) is an inflammatory disorder that affects the apocrine gland-bearing regions. There is currently no population-based study of HS in Nigeria. The purpose of this study was to investigate the prevalence of HS in Abuja, Nigeria's federal capital territory.

METHODS

This is a cross-sectional study of healthy adults accompanying patients to the outpatient clinics of the tertiary hospital in Abuja, utilizing the Global Hidradenitis Suppurativa Atlas (GHiSA) questionnaire as part of the GHiSA program.

RESULTS

The prevalence of HS in 898 participants was 3.3% (95% confidence interval (CI): 2.3%-4.7%). Participants with HS had a significantly higher body mass index than those without (p value of 0.038). One out of the 30 HS participants had a Hurley score of 2, while the rest had a Hurley score of 1. The majority of participants (49%) exhibited HS symptoms involving the axilla. The GHiSA questionnaire has a sensitivity rate of 93.8% (95% CI: 79.2%-97.3%) and a specificity rate of 93.8% (95% CI: 88.2%-97.3%).

CONCLUSION

The prevalence of HS in our study (3.3%) was higher than that seen in hospital records (0.47%). This demonstrates that most HS patients present to the dermatology outpatient clinics when the disease is severe. </p>.
