New insights in hidradenitis suppurativa from a population-based Dutch cohort: prevalence, smoking behaviour, socioeconomic status and comorbidities.

ABSTRACT:

Background

Hidradenitis suppurativa (HS) is a chronic autoinflammatory skin condition and is associated with several comorbidities. Previous studies report variable prevalence rates of HS, depending on the methodology. However, the exact prevalence remains unknown.

Objectives

To estimate the prevalence of HS in a large population-based cohort in the Northern Netherlands, and to compare patients with HS to the general population, investigate characteristics and identify potential associated comorbidities.

Methods

Data were collected through a cross-sectional survey-based study within the Lifelines Cohort Study (n = 167 729), based on the general population located in the Northern Netherlands. A digital self-reported questionnaire was developed consisting of validated questions for determining HS.

Results

Among 56 084 respondents, the overall prevalence of HS was 2.1% [95% confidence interval (CI) 2.0-2.2]. The respondents with HS had lower socioeconomic status than the controls (P < 0.001) and more frequently currently smoked (P < 0.001). Several new significant associations in patients with HS were revealed, such as fibromyalgia (OR 2.26, 95% CI 1.64-3.11), irritable bowel syndrome (OR 1.63, 95% CI 1.18-2.26), chronic fatigue syndrome (OR 1.72, 95% CI 1.06-2.78) and migraine (OR 1.48, 95% CI 1.11-1.96). Fibromyalgia and chronic fatigue syndrome remained significantly associated with HS in the multivariate analysis after adjusting for age, sex, body mass index, smoking status and socioeconomic status.

Conclusions

Our study showed a higher prevalence of HS in the Northern Netherlands compared with the overall estimated prevalence of 1% and identified several new associated comorbidities.

Project description:ImportanceChronic pain is one of the most prominent symptoms of hidradenitis suppurativa (HS) and an independent domain in the core outcome set for HS. Previously, the chronic, recurrent, inflammatory nature of HS was hypothesized to induce central sensitization (CS; alteration and amplification of pain perception). However, evidence for this hypothesis is currently lacking.ObjectiveTo determine the prevalence of CS in patients with HS compared with sex- and age-matched controls.Design, setting, and participantsThis was a cross-sectional, survey-based, case-control study conducted from February to November 2020 that included all consecutive adult patients with HS attending the outpatient clinic of the Department of Dermatology of the Erasmus University Medical Center Rotterdam, in Rotterdam, the Netherlands. Age- and sex-matched controls without chronic inflammatory dermatologic diseases were recruited from the same department.Main outcomes and measuresThe main outcome was the Central Sensitization Inventory (CSI) score (ranging from 0-100) as a screening tool for presence of CS. Based on current literature, a score of 40 or higher was deemed to indicate the presence of CS.ResultsOverall, 100 patients with HS (median [IQR] age, 34.5 [27.3-47.0] years; 71 [71%] female) and 100 controls (median [IQR] age, 33.5 [27.0-48.8] years; 71 [71%] female) were included, of which 36% and 12%, respectively, had a CSI score of 40 or higher (P < .001). Multivariate logistic regression showed that patients with HS had 4.46 (95% CI, 1.89-10.52; P = .001) times the odds of having a positive CSI compared with controls. In addition, CS was significantly associated with previously diagnosed depression (odds ratio, 6.16; 95% CI, 2.81-13.54; P < .001). No association between CSI score and disease severity was found.Conclusions and relevanceIn this cross-sectional, case-control study, patients with HS had more than 4 times the odds of having CS, indicated by a positive CSI, compared with age- and sex-matched controls. This new insight in the presence of CS in patients with HS raises the question of whether we are adequately measuring and treating HS-associated pain. Active screening for CS and depressive symptoms in patients with a discrepant pain experience is recommended.

Project description:ImportanceHidradenitis suppurativa/acne inversa (HS) is a chronic inflammatory skin disease characterized by occlusion of hair follicles as a primary pathogenic factor. There are scarce data regarding the prevalence of HS.ObjectiveTo estimate overall HS prevalence.Data sourcesThis review and meta-regression analysis was conducted using the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline. The academic search included PubMed, Cochrane registry, ClinicalTrials.gov, and evidence by NHS UK and Trip databases from inception through May 2020. To analyze HS prevalence, only cross-sectional studies or baseline assessments of longitudinal cohorts using census-based surveys or probabilistic and nonprobabilistic epidemiologic methods were considered. The search terms were (prevalence OR incidence OR epidemiology) AND (hidradenitis suppurativa OR acne inversa OR Verneuil's disease). No language restriction was applied.Study selectionOriginal investigations that reported HS prevalence were included. After exclusion criteria were applied, 17 studies qualified for qualitative analysis, but only 16 studies were quantitatively assessed.Data extraction and measuresTwo reviewers extracted data by age, diagnostic criteria, presence of any comorbidity, sample sizes, continent/location, sex, and other characteristics. Assessment of bias risk used the Joanna Briggs Institute Critical Appraisal Instrument for Studies Reporting Prevalence Data using random-effects models to synthesize available evidence.Main outcomes and measuresHidradenitis suppurativa prevalence (with 95% CI) among the overall population and among subgroups. Between-study heterogeneity was assessed (Cochran Q statistic) and quantified (I2 statistic).ResultsIn 16 quantitatively assessed studies included, prevalence estimates were reported only from Western European and Scandinavian countries, the US, and Australia. Meta-analysis with random effects, after adjusting for publication bias in the prevalence estimates, revealed a 0.40% prevalence (95% CI, 0.26%-0.63%) for HS. Studies based on clinical samples revealed a higher pooled prevalence of HS (1.7%) than population-based studies (0.3%).Conclusions and relevanceThe findings of this systematic review and meta-regression analysis may help facilitate policy formulation, channeling funding and guiding principles for better disease diagnosis using universal valid tools and management.

Project description:It is a matter of speculation whether the high prevalence of smoking among Hungarian Roma (HR) is related to genetic, gene-environmental interactions or cultural factors. Our aim is to compare the genetic susceptibility and possible effects of determinants associated with smoking behaviours in the Hungarian general (HG) and Roma populations. A complex health survey including three pillars (questionnaire, physical and laboratory examinations) was carried out (NHG = 412 and NHR = 402). Risk allele frequencies of ten single-nucleotide polymorphisms (SNPs) were compared, and their combined effect was estimated by computing unweighted and weighted genetic risk scores (GRS, wGRS). The effects of genetic and environmental factors were investigated in regression analyses after confounders were introduced. Socio-economic status (SES) was calculated based on the Kuppuswamy scale 2019. Risk allele frequencies of only four SNPs were found to be different between populations (p < 0.01). Median values of GRS did not differ, while the wGRS median was slightly higher among Roma individuals (5.2 vs. 4.9; p = 0.02). Roma individuals were more likely to be heavy smokers (ORmales = 2.05, 95% CI [1.47-2.86]; ORfemales = 1.89, 95% CI [1.58-2.25]. Smokers have lower SES compared to never smokers (SES βHR = -0.039, p = 0.023; βHG = -0.010, p = 0.049). An inverse relationship was found between SES and smoking behaviours (p < 0.0001) and was found to be a better predictor of smoking behaviours than genetic susceptibility. Our study findings suggest that the high prevalence of smoking behaviours and nicotine-dependence were not revealed to have a genetic susceptibility among HR individuals; therefore, the highest efforts should be focused on targeting SES-related factors in the Roma population. Strengths of the study: This is the first study carried out to investigate and detect the most relevant factors and the possible genetic background of the extremely high prevalence of smoking based in the Roma population. Limitations of the study: No standard instrument has been used to assess the intensity of addiction to nicotine. Because of some participants' unwillingness to define themselves as Roma, the overall HR population was not represented by the sample of this study.
