Prevalence of Neuropathic Pain and Related Characteristics in Hidradenitis Suppurativa: A Cross-Sectional Study.

ABSTRACT: Pain is a core symptom of hidradenitis suppurativa (HS) and is of complex, multifactorial origin. HS patients frequently report typical neuropathic pain qualities, but its prevalence has been poorly described. In this cross-sectional study, we examine the prevalence of neuropathic pain (NP) component and related pain-characteristics of a hospital-based cohort of patients with symptomatic HS. We administered the pain-DETECT tool (PDQ), a validated screening tool for NP, collecting clinical and patient-reported data on pain, pruritus and pain-management. We obtained 110 complete datasets from symptomatic HS patients (49.1% females; Hurley I (27.3%])-II (45.5%)-III (27.3%)). According to the PDQ tool, 30% of patients were classified with a high probability (>90%) of neuropathic pain (LNP). LNP status was significantly associated with increased pain severity, disease activity, pruritus intensity and use of pain medication. Regression analysis showed a significant impact of the PDQ score on patient-reported outcomes, including pain severity and the dimensions of activity and affective pain interference. HS patients may present a mixed chronic pain phenotype with a neuropathic component, thus requiring additional pain-assessments. A multi-modal approach to pain management, in combination with disease-specific treatment, should be implemented in future interventional studies.

Project description:BackgroundHidradenitis Suppurativa (HS) is a painful, chronic inflammatory skin disease. Global estimates of prevalence vary between 0.03% and 4% of the population. Our main aim was to determine HS prevalence in the Australian adult population focussing on the demographics, management pathways and diagnosis rate of individuals living with HS.MethodsIn this population-based cross-sectional study, 17,050 individuals representative of the Australian adult population were asked through face-to-face household interviews to answer a previously validated HS screening questionnaire with high diagnostic power. Individuals who screened positive were asked additional questions, including previous diagnosis of HS and number/type of physicians consulted regarding their condition.Results11,433 Australian residents answered the HS questionnaire, 88 screening positive for HS (0.77%; 95% CI 0.62-0.95). Considering the previously reported sensitivity (0.97) and positive predictive value (0.85) of the screening questionnaire, HS prevalence was estimated to be 0.67% (95% CI 0.53%-0.84%). 6 of 88 suspected HS individuals reported a pre-existing HS diagnosis (6.8%; 95% CI 3.2%-14.1%). 25.6% of the undiagnosed individuals suspected of having HS had not seen any clinicians regarding their boils; the remaining ones had consulted General Practitioners (96.7%), and clinicians from different specialties. Comparisons of individuals who screened positive for HS versus those who screened negative demonstrated statistically significant differences in gender (p = 0.0046), age (p<0.0001), BMI (p = 0.0307), smoking status (p<0.0001), employment status (p<0.0001) and income (p = 0.0321).ConclusionsThe prevalence of HS in Australia was estimated to be 0.67% (95% CI 0.53%-0.84%). The diagnosis rate amongst the suspected HS cases was low, which appeared to be due to a combination of patients not seeking help and decentralization of care. Individuals suspected of having HS were more likely to be females, young, obese, smokers, unemployed or at home duties and having lower annual personal income in comparison with individuals not suspected of having HS.

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 is a chronic, inflammatory skin disease in which genetic factors are considered to play a role, with up to 38% of patients reporting a family history. Variations in the γ-secretase genes are found mainly in familial cases with an autosomal dominant pattern of inheritance. These variations are rare in the general population with hidradenitis suppurativa, even in patients who report a family history of the disease.ObjectiveTo assess the heritability of hidradenitis suppurativa in a nationwide Dutch twin cohort.Design, setting, and participantsIn this cross-sectional study on self-reported hidradenitis suppurativa conducted from 2011 to 2016, data were collected from twins participating in the surveys of the nationwide Netherlands Twin Register. All complete twin pairs answering the question on hidradenitis suppurativa in the survey were included: 978 female monozygotic twin pairs and 344 male monozygotic twin pairs and 426 female dizygotic twin pairs, 167 male dizygotic twin pairs, and 428 dizygotic twin pairs of the opposite sex. Statistical analysis was performed from July to November 2019.Main outcomes and measuresThe main outcome is the proportion of susceptibility to hidradenitis suppurativa due to additive genetic factors (narrow-sense heritability), dominant genetic factors, common or shared environmental factors, or unshared or unique environmental factors. The main outcome was evaluated prior to data collection.ResultsThe prevalence of hidradenitis suppurativa among twin pairs was 1.2% (58 of 4686); the mean (SD) age was 32.7 (15.4) years. The narrow-sense heritability of hidradenitis suppurativa was 77% (95% CI, 54%-90%), with the remainder of the variance due to unshared or unique environmental factors based on an age-adjusted model combining additive genetic factors and unshared or unique environmental factors.Conclusions and relevanceThe high heritability found in this study suggests a stronger than previously assumed genetic basis of hidradenitis suppurativa. Environmental factors were also shown to contribute to the susceptibility to hidradenitis suppurativa, supporting a multifactorial cause of the disease. Moreover, the results of this study strongly support the need for a global genome-wide association study in the general population of patients with hidradenitis suppurativa.
