Researchers reviewed clinical features of hidradenitis suppurativa and provided strategies to promote earlier identification, differentiation from common mimickers, and timely referrals for multidisciplinary management.
Hidradenitis suppurativa (HS) is a chronic, progressive inflammatory disease of the skin that is frequently underdiagnosed and/or misdiagnosed, in part due to its heterogeneity in presentation and low disease recognition.
Authors of a review published in The American Journal of Medicine sought to provide a comprehensive overview of the disease features associated with HS to facilitate earlier identification, differentiation from common mimickers, and timely referrals for multidisciplinary management when needed.
“Because of poor recognition of HS within the medical community, the average time between onset of symptoms to diagnosis is approximately 10 years. During this period, patients may experience disease progression that can lead to disfigurement and disability. Additionally, patients often experience fragmented care for flare management at acute and ambulatory care facilities with a variety of providers,” noted the study authors.
Clinical Presentation and Comorbidities
In the absence of a diagnostic biomarker, HS is characterized by 3 major diagnostic criteria: painful nodules, abscesses, and draining tunnels on the skin; involvement of typical anatomic sites (eg, axillae, inframammary and intermammary folds); recurrence and chronicity.
HS onset most commonly occurs in early adulthood. Women are shown to be predominantly affected by HS, with a disproportionate impact shown among Black individuals, who were found in a recent study to be more likely to experience greater disease severity, emergency department visits, hospitalizations, and surgeries than non-Hispanic White patients.
Pain, drainage, and odor are among the most burdensome symptoms of the disease, with a substantial quality of life impact also reported among patients.
“There is an opportunity for primary care and specialty providers to support timely recognition of HS and screening/management for the numerous comorbid conditions associated with the disease,” the authors wrote.
Common comorbidities in HS include endocrine and metabolic-related conditions, cardiovascular disease, obstetric risks, gastrointestinal disorders, musculoskeletal diseases, and mental health disorders. Mental health disorders of depression, anxiety, and substance abuse disorder are notable risk factors, with rates of death by suicide more than doubled in patients with HS.
“The substantial emotional and psychological impact of hidradenitis suppurativa has also been associated with low self-esteem and poor body image, which can negatively impact social and intimate relationships,” the authors noted.
They also wrote that primary care providers have an important role in managing and coordinating care for the treatment of mental and psychological comorbidities to help manage and improve HS disease burden. They also called for a comprehensive comorbidity screening strategy for patients with HS to achieve and maintain overall health.
Therapeutic Options and Disease Management
Treatment and management of HS should be through a multifaceted approach to care, the researchers explained, which includes medical and surgical management, as well as screening for and managing associated comorbidities. Several treatment options are available for the disease:
Further strategies touted by the reseachers to improve care management included referral to resources that can support awareness in and education of patients with HS related to disease course, disease impact, and opportunities to engage behaviors that may support overall health. Better understanding of the inflammatory nature of HS and the potential for immunomodulating therapies to control disease symptoms were also mentioned as examples of key information to provide patients with HS.
“Timely disease recognition and management are essential to controlling symptoms, mitigating disease progression, and improving quality of life for patients with HS,” the researchers concluded. “Comprehensive care strategies coordinated among medical and surgical disciplines are necessary to improve the overall health of patients with HS.”
