Clinical Implementation of Biologics and Small Molecules in the Treatment of Hidradenitis Suppurativa.

ABSTRACT: Hidradenitis suppurativa (HS) is a chronic, recurrent, auto-inflammatory skin disease originating from the hair follicles. The typical inflammatory nodules, abscesses, and draining sinus tracts (tunnels) are characterized by a massive influx of neutrophils, macrophages, B-cells, plasma cells, T helper (Th)1, Th17 cells and upregulation of pro-inflammatory cytokines such as IL-1, IL-17, IL-12/23, and TNF-α. Over the last decades, several clinical trials evaluated the clinical efficacy of different biologics targeting these pro-inflammatory cytokines, in particular TNF-α and IL-1. However, adalimumab is still the only registered drug for HS. This review discusses biologics and small molecules with high level of evidence for their clinical application, provides guidance on when and how to use these biologics and small molecules in clinical practice, and elaborates on the combination with medical and surgical treatment options beyond the current guidelines. Furthermore this review provides an overview of potential biologics and small molecules currently under investigation for novel targets in HS such as IL-36, C5a, Janus kinase family members, CD-40, LTA4 and CXCR1/2.

Project description:Hidradenitis suppurativa (HS) leads to disfigurement and painful eruptions in terminal hair follicles of the intertriginous skin, mainly of axillary, genitofemoral, and perianal sites. It is associated with an excessive impairment of quality of life, psychiatric disorders, and sexual distress. Body image impairment has been linked to depression and anxiety and has been described for some dermatologic disorders but has not yet been investigated in patients with HS.To investigate whether body image is diminished in patients with HS and whether disease severity, age at onset, disease duration, obesity, depression, and anxiety are linked to body image impairment.This 12-month (August 1, 2009, to August 31, 2010) case-control study with a prospective, observational, cross-sectional design recruited 47 consecutive patients with HS entering a tertiary care center and 45 healthy control individuals matched for age, sex, and body mass index (BMI). One patient and 4 controls failed to complete the questionnaire and were excluded from the evaluation. Data analysis was performed from December 1, 2013, to February 15, 2014.The Frankfurt Body Concept Scale (FKKS) and the Hospital Anxiety and Depression Scale (HADS) were given to patients and controls. Correlations among FKKS, HADS, and disease features were calculated.Of the 46 patients and 41 controls included in the evaluation (mean [SD] age, 35.6 [1.6] years; 40 [46%] male and 47 [54%] female), HS significantly reduced body image (mean FKKS score, 234.2 [5.4] in patients and 276.9 [5.7] in controls; P < .001), even when controlled for BMI. A correlation was found for the extent of body image disruption and BMI (r = -0.589; P < .001), HADS-depression score (r = -0.619; P < .001), and HADS-anxiety score (r = -0.340; P = .03). No association was found for the body image score and the severity of HS, age at onset of disease, and duration of disease. The body contact subscale score was the only subscale score that was not different between patients with HS and controls.Patients with HS have major body image impairment, which might lead to depression and anxiety, disorders that have been largely acknowledged in HS. This study identified another element of the psychosocial burden of patients with HS and reveals that body image could potentially be used as an outcome measure in future studies of HS.
