Kjærsgaard Andersen R, Pedersen O, Eidsmo L, Jemec G, Saunte D. Initial steps towards developing a predictive algorithm of disease progression for hidradenitis suppurativa (HS): results from a Cox proportional hazard regression analysis on disease progression among a cohort of 335 Danish patients with HS. Br J Dermatol 2024; 190:904-914. [PMID: 38169316 DOI: 10.1093/bjd/ljad530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 12/19/2023] [Accepted: 12/21/2023] [Indexed: 01/05/2024]
Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory and scarring disease with a wide spectrum of disease severity. The amount of scarring is proportional to the preceding tissue damage and poses a challenge to patients. Severe HS is most often treatment recalcitrant, but hypothetically avoidable through early biologic treatment. Early prediction of individual risk of disease progression is therefore essential for patient management. OBJECTIVES To investigate risk factors associated with disease progression and to design an algorithm capable of predicting disease -progression. METHODS A prospective cohort study of 335 Hurley III-naïve patients with HS, not treated with biologics, was followed for a median of 2 years. Potential risk factors covered basic demographics, HS anamnestic factors and clinical HS factors collected during physical examination. Two separate Cox proportional hazard regression (CPHR) analyses were conducted. A summated 'progression score' was calculated and used in the predictive algorithm of severe disease. Subsequent bootstrap sampling was used to validate the predictability of the predictive algorithm. RESULTS The CPHR analysis of Transition to severe disease found that active smoking [hazard ratio (HR) 4.01, 95% confidence interval (CI) 1.71-9.40, P = 0.001]; body mass index (BMI) points > 25 at baseline (each point: HR 1.06, 95% CI 1.02-1.09, P < 0.001); active disease in 2 (HR 4.26, 95% CI 1.23-14.84, P = 0.02) and ≥ 3 areas (HR 6.54, 95% CI 1.89-22.72, P = 0.003) all constituted substantial risk factors. Conversely, the CPHR analysis of Disease progression did not yield results of clinical relevance. A 'progression score' of 3.04 was used as a threshold in the predictive algorithm of Transition to severe disease and achieved the following test specifics: sensitivity = 0.51, specificity = 0.86, positive predictive value = 0.50, negative predictive value = 0.86. CONCLUSIONS We found a disparity between factors increasing the risk of simple Disease progression and those increasing the risk of Transition to severe disease. For the latter, active smoking, BMI points > 25, active disease in 2 or ≥ 3 areas were all shown to be the clinically relevant factors that could be used to construct an algorithm that correctly predicted progression to severe HS in more than half of all instances.

Abstract
BACKGROUND Actinic keratosis (AK) is a common dermatological condition, and among the most common dermatological diagnoses in older populations. Although the prevalence of AK depends on demographic and environmental factors, little is known about the global context of AK. OBJECTIVES To provide a comprehensive and updated analysis of the global prevalence rate and incidence of AK in the general population through a systematic review and meta-analysis, and - through subgroup analyses - to identify high-risk phenotypes, demographic and lifestyle risk factors and regional variations in disease prevalence. METHODS A systematic search of Embase, MEDLINE, Web of Science and Google Scholar was performed on 20 May 2022. Two reviewers independently screened and assessed the quality of each study using a validated critical appraisal checklist. Epidemiological measurements (e.g. prevalence) from individual studies performed in the general population were then pooled in a random-effects meta-analysis. Subgroup analyses (i.e. population age, geographical region, occupation, sex and study quality) were conducted. RESULTS Of the 65 articles that made it through the full-text screening, 60 reported a point prevalence. A meta-analysis of these articles yielded an overall point prevalence of 14% [95% confidence interval (CI) 14-15]. In further analyses, the calculated prevalence rate varied depending on subgroup. The pooled incidence rate from the seven eligible studies analysed was 1928 per 100 000 person-years (PY; 95% CI -439 to 4294). CONCLUSIONS This comprehensive meta-analysis provides an updated global prevalence rate of AK of 14%, indicating a significant worldwide disease burden. The incidence rate of AK was found to be 1928 per 100 000 PY, emphasizing a growing public health concern. However, high heterogeneity among studies suggests that various factors influence the AK prevalence rate, necessitating further research to understand the observed differences.

New Insights in Hidradenitis Suppurativa from a Population-based Dutch Cohort: Prevalence, Smoking Behaviour, Socioeconomic Status and Comorbidities. Br J Dermatol 2021; 186:814-822. [PMID: 34921556 PMCID: PMC9321679 DOI: 10.1111/bjd.20954] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 10/26/2021] [Accepted: 12/06/2021] [Indexed: 11/28/2022]
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.

Abstract
We aimed to (1) evaluate the incidence of tuberculous pleural effusion (TPE) over 25 years in our centre; (2) measure the yield of different diagnostic techniques; (3) compare TPE features between immigrant and native patients. Retrospective study of patients who underwent diagnostic thoracentesis and pleural biopsy in our hospital between 1995 and 2020. TPE was diagnosed in 71 patients (65% natives, 35% immigrants). Onset was acute in 35%, subacute in 26% and prolonged in 39%. Radiological features were atypical in 42%. Thoracentesis specimens were lymphocyte-predominant in 84.5% of patients, with elevated adenosine deaminase in 75% of patients. Diagnostic yield of pleural biopsy was 78%. Compared with native patients, more immigrants had previous contact with TB (54% vs. 17%, p = 0.001), prior TB (21% vs. 4%, p < 0.02) and atypical radiological features (58% vs. 34%, p < 0.03). TPE incidence was six times higher in the immigrant population (6.7 vs. 1.1 per 100,000 person-years, p < 0.001). TPE has an acute onset and sometimes atypical radiological features. Pleural biopsy has the highest diagnostic yield. Reactivation, prior contact with TB, atypical radiological features, complications, and positive microbiology results are more common in immigrant patients.

Migrants' and refugees' health status and healthcare in Europe: a scoping literature review. BMC Public Health 2020; 20:1039.

Abstract
BACKGROUND There is increasing attention paid to the arrival of migrants from outwith the EU region to the European countries. Healthcare that is universally and equably accessible needs to be provided for these migrants throughout the range of national contexts and in response to complex and evolving individual needs. It is important to look at the evidence available on provision and access to healthcare for migrants to identify barriers to accessing healthcare and better plan necessary changes. METHODS This review scoped 77 papers from nine European countries (Austria, Cyprus, France, Germany, Greece, Italy, Malta, Spain, and Sweden) in English and in country-specific languages in order to provide an overview of migrants' access to healthcare. The review aims at identifying what is known about access to healthcare as well as healthcare use of migrants and refugees in the EU member states. The evidence included documents from 2011 onwards. RESULTS The literature reviewed confirms that despite the aspiration to ensure equality of access to healthcare, there is evidence of persistent inequalities between migrants and non-migrants in access to healthcare services. The evidence shows unmet healthcare needs, especially when it comes to mental and dental health as well as the existence of legal barriers in accessing healthcare. Language and communication barriers, overuse of emergency services and underuse of primary healthcare services as well as discrimination are described. CONCLUSIONS The European situation concerning migrants' and refugees' health status and access to healthcare is heterogeneous and it is difficult to compare and draw any firm conclusions due to the scant evidence. Different diseases are prioritised by different countries, although these priorities do not always correspond to the expressed needs or priorities of the migrants. Mental healthcare, preventive care (immunization) and long-term care in the presence of a growing migrant older population are identified as priorities that deserve greater attention. There is a need to improve the existing data on migrants' health status, needs and access to healthcare to be able to tailor care to the needs of migrants. To conduct research that highlights migrants' own views on their health and barriers to access to healthcare is key.

Abstract
Scabies is a highly contagious, globally prevalent, parasitic skin infestation caused by Sarcoptes scabiei var. hominis, also known as the itch mite. There have been outbreaks not only in the developing world, but also in the developed world among refugees and asylum seekers. Once infested with scabies mites, symptomatic patients, as well as asymptomatic carriers, quickly spread the disease through direct skin-to-skin contact. Typically, symptoms of scabies are characterized by an erythematous, papular, pruritic rash associated with burrows. Treatment of scabies involves using topical or systemic scabicides and treating secondary bacterial infections, if present. Given the prevalence and contagiousness of scabies, measures to prevent its spread are essential. Through application of the novel Identify-Isolate-Inform (3I) Tool, emergency medical providers can readily identify risk factors for exposure and important symptoms of the disease, thus limiting its spread through prompt scabicide therapy; isolate the patient until after treatment; and inform local public health authorities and hospital infection prevention, when appropriate. Ultimately, these three actions can aid public health in controlling the transmission of scabies cases, thus ensuring the protection of the general public from this highly contagious skin infestation.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic, debilitating inflammatory skin disease. In Germany, there are no population-based data on the epidemiology of HS. OBJECTIVES The objective of this study was to examine the occurrence of HS in inpatient as well as in outpatient settings. METHODS We used three data sources for analysing the prevalence, incidence and case-related occurrence of HS in different settings: data of two German statutory health insurance (SHI) companies and hospital discharge data provided by the Federal Statistical Office. The studied period was from 2010 to 2015. RESULTS In a representative sample of about 2.3 million insurees (out of 5.9 million total persons) of the SHI DAK-Gesundheit, 791 were diagnosed with HS in 2010. This coding prevalence of 0.03% is in accordance with the data of another SHI (Barmer) on about 9 million total insurees. In 2015, at least 34.7% of incident persons with HS had one potential misdiagnosis in 2014. CONCLUSION This population-based study analyses the prevalence and incidence of HS in Germany. The coding prevalence of 0.03% observed in two independent SHI data sets is lower than expected. The findings of considerable potential misdiagnosis add to the underdiagnosis of HS in general and underline the need for future strategies to early detection and valid diagnosis of HS.

Abstract
BACKGROUND Alopecia areata (AA) is a common autoimmune alopecia with heterogeneous severity and distribution. Previous studies found conflicting results about AA epidemiology. OBJECTIVE To determine the prevalence, incidence, and predictors of AA, alopecia totalis, alopecia ophiasis, and alopecia universalis. METHODS A systematic review of all published cohort and cross-sectional studies that analyzed AA and its subtypes. MEDLINE, Embase, LILACS, Scopus, Cochrane Library, and GREAT were searched. At least 2 reviewers performed study title/abstract review and data extraction. Random-effects meta-analysis was used because of significant heterogeneity (I2 = 99.97%). RESULTS Ninety-four studies met the inclusion criteria. The pooled prevalence (95% confidence interval, N) of AA overall was 2.11% (1.82-2.42, N = 302,157,365), with differences of population-based (0.75% [0.49-1.06%], N = 301,173,403) and clinic-based (3.47% [3.01-3.96], N = 983,962) studies. The prevalences of alopecia totalis, ophiasis, and universalis were 0.08% (0.04-0.13, N = 1,088,149), 0.02% (0.00-0.06, N = 1,075,203), and 0.03% (0.01-0.06, N = 1,085,444), respectively. AA prevalence (95% confidence interval) increased over time (<2000: 1.02% [0.85-1.22]; 2000-2009: 1.76% [1.51-2.03]; >2009: 3.22% [2.59-3.92]; P < .0001) and differed by region. AA prevalence was significantly lower in adults (1.47% [1.18-1.80]) than children (1.92% [1.31-2.65]; P < .0001). CONCLUSIONS AA affects 2% of the global population. AA prevalence is lower in adults than children, is increasing over time, and significantly differs by region.

Abstract
Keratosis pilaris is a common skin disorder comprising less common variants and rare subtypes, including keratosis pilaris rubra, erythromelanosis follicularis faciei et colli, and the spectrum of keratosis pilaris atrophicans. Data, and critical analysis of existing data, are lacking, so the etiologies, pathogeneses, disease associations, and treatments of these clinical entities are poorly understood. The present article aims to fill this knowledge gap by reviewing literature in the PubMed, EMBASE, and CINAHL databases and providing a comprehensive, analytical summary of the clinical characteristics and pathophysiology of keratosis pilaris and its subtypes through the lens of disease associations, genetics, and pharmacologic etiologies. Histopathologic, genomic, and epidemiologic evidence points to keratosis pilaris as a primary disorder of the pilosebaceous unit as a result of inherited mutations or acquired disruptions in various biomolecular pathways. Recent data highlight aberrant Ras signaling as an important contributor to the pathophysiology of keratosis pilaris and its subtypes. We also evaluate data on treatments for keratosis pilaris and its subtypes, including topical, systemic, and energy-based therapies. The effectiveness of various types of lasers in treating keratosis pilaris and its subtypes deserves wider recognition.

Abstract
BACKGROUND Data on the health care utilization of patients with hidradenitis suppurativa (HS) in primary care settings are scarce. OBJECTIVE To investigate the health care service utilization of patients with HS. METHODS In a cross-sectional study, patients with HS were compared with 2 age- and sex-matched control groups-general population enrollees of Clalit Health Services and a group of patients with psoriasis. Health care services data included inpatient and outpatient community clinic visits and pharmacy claims for topical and systemic treatments. Multivariate analysis of the data for patients with HS and controls was performed. RESULTS The study included 4417 patients with HS, 22,085 general population enrollees, and 4417 patients with psoriasis. On the basis of multivariate analyses, patients with HS had more annual dermatology clinic visits compared with the general population enrollees (odds ratio [OR], 6.49; 95% confidence interval [CI], 7.06-5.97) and patients with psoriasis (OR, 1.32; 95% CI, 1.44-1.21), more annual surgical clinic visits (OR, 3.78; 95% CI 3.28-4.36 and OR, 1.65; 95% CI, 1.42-1.91, respectively), and more hospitalizations (OR, 2.21; 95% CI, 1.89-2.56 and OR, 1.51; 95% CI, 1.28-1.78, respectively). LIMITATIONS Underestimation of HS frequency was possible. CONCLUSIONS The burden on health care systems due to patients with HS is greater than that due to patients with psoriasis and the general population.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory disease involving painful, deep abscesses and chronic, draining sinus tracts. Because of the variable signs and symptoms displayed by patients, it remains widely unrecognized and difficult to treat, resulting in significant diagnostic delay and inconsistent treatment process. No medical specialty has successfully designated a criterion standard of treatment, resulting in variable care and unmet patient needs. Widespread causes and effects of HS are difficult to determine because the prevalence is dependent on a variety of things, including how and where data are collected, resulting in significant bias. Therefore, the task must be to assess existing studies to produce a best estimate of prevalence. In addition, the 3 types of studies available for HS (ie, self-report, registry-based, and group examination studies) must be evaluated because each offers important insights into who is impacted by this disease. The exact prevalence of HS remains unknown because of the difficulty in collecting and extrapolating data and the usefulness of studies; however, high comorbidity and disease severity is observed, resulting in increased hospital visits for patients with HS--nearly double that of other diseases. Finally, comparisons between HS and psoriasis are worth mentioning because the similarities are clear, but the severity of HS appears to be more debilitating in many aspects of life. This article will address the epidemiology of HS through current available research.

Abstract
Hidradenitis Suppurativa (HS) is an uncommon disease, which is particularly rare in young and prepubescent children. HS pathology centers on the follicular unit and involves aberrant cutaneous cellular immunity. HS tends to first manifest in puberty, but a handful of prepubescent cases of HS have been reported and are linked to hormonal disorders, in particular elevated testosterone. The most common manifestations of HS are abscesses, scarring, acne inversa, and keloids, especially in the intertriginous areas of the groin and the axilla. Treatments including topical anti-infectives including chlorhexidine wash, topical clindamycin, tretinoin cream, and azelaic acid cream, which may be of limited use because bacteria involved in HS likely create biofilms. Oral agents include clindamycin with or without rifampin for short-term usage. Cases resistant to conservative therapy have been reported to respond to finasteride, onabotulinumtoxin, or microfractionated 10,600-nm CO2 laser.

Abstract
Hidradenitis suppurativa (HS) is a burdensome disease and has the potential to affect the life course of patients. It is a rare disease in children, and the recorded literature is correspondingly scarce. This article reviews the therapeutic options for HS in children and adolescents, and highlights particular differences or challenges with treating patients in this age group compared with adults. The work-up of paediatric patients with HS should include considerations of possible endocrine co-morbidities and obesity. Medical therapy of lesions may include topical clindamycin. Systemic therapy may include analgesics, clindamycin and rifampicin, finasteride, corticosteroids or tumour necrosis factor alpha (TNFα) blockers. Superinfections should be appropriately treated. Scarring lesions generally require surgery.

Abstract
INTRODUCTION Previous studies in Spain have shown that the foreign and immigrant populations can have different diseases to Spanish-born individuals. However, no comparative study has specifically investigated foreign children in Spain. MATERIAL AND METHODS The objective of the study was to compare skin diseases in foreign children with those in children born in Spain of Spanish parents. We included all patients under 15 years of age who were seen in our dermatology department between January 2007 and December 2007. RESULTS During the study period, 3108 pediatric patients were seen in the dermatology department. Of these, 2661 (85.6%) were Spanish and 447 (14.3%) were foreigners. Foreign children sought medical care more often (11.4%) than Spanish children (6%) (P<.001) and made less use of the specialist outpatient clinic (59.6% vs 68.8% [P<.001]) and more use of emergency care. Complaints observed more frequently in the foreign children were scabies (adjusted odds ratio [aOR], 10.6; 95% CI, 4.71-24.10), arthropod bites (aOR, 2.80; 95% CI, 1.14-6.87), hypopigmentation (aOR, 2.61; 95% CI, 1.06-6.44), and atopic dermatitis (aOR, 1.65; 95% CI, 1.19-2.31). Melanocytic nevus was observed more frequently in Spanish children (aOR, .50; 95% CI, .30-.83). CONCLUSIONS Differences between children born in Spain of Spanish parents and foreign children were found for type of visit and frequency of skin diseases.

Abstract
PURPOSE OF REVIEW Scabies is a common skin infestation globally, particularly in the developing world. With the launch of the International Alliance for the Control of Scabies (IACS) in 2012, this review aims to present the recent evidence of the current epidemiological situation for scabies across the globe. Mindful of the fact that the downstream complications of scabies infestations, pyoderma, streptococcal glomerulonephritis and subsequent chronic renal impairment and rheumatic fever, have been recognized as being more significant to global health than previously acknowledged, the review focusses also on the epidemiological evidence from developing countries. RECENT FINDINGS Scabies occurrence rates vary in the recent literature from 2.71 per 1000 to 46%. Although it is responsible for larger disease burdens and complications such as pyoderma and renal and heart disease in the tropics, scabies outbreaks in the developed world amongst vulnerable communities and health institutions contribute a significant cost to the health services managing them. SUMMARY Scabies remains common across the world, but is such a health issue in the developing world that the suggestion that it be considered a neglected tropical disease is a pertinent one. Standardized diagnostic criteria and even a point-of-care diagnostic test would be a major contribution to the understanding of this epidemic.
