A cross-sectional study was conducted involving 94 patients with HS. Noninvasive methods were employed to diagnose MASLD. The clinical diagnosis was based on altered transient elastography–controlled attenuation parameter as surrogate for liver steatosis and the presence of cardiometabolic risk factors after excluding secondary causes of steatosis. Statistical analyses included logistic regression models to identify predictors of MASLD risk. The study found a prevalence of MASLD as high as 75% measured by high-accuracy transient elastography among patients with HS. Multivariable logistic regression analysis showed a strong within-cohort association between HS and MASLD. The newly developed clinical algorithm integrating transient elastography and the Fatty Liver Index effectively stratified MASLD risk. Our findings underscore the importance of routine MASLD screening in HS.

A functional β2-adrenergic receptor agonist network exists in the skin, which can alter skin cell migration and proliferation, inhibit angiogenesis, and alter wound re-epithelialization, suggesting a potential role for a β2-adrenergic receptor agonist applied topically for the prevention and treatment of scarring. Reduced scarring has been observed in an in vivo pig model, whereby a 50% reduction in skin scar area and hyperpigmentation was observed after topical application of salbutamol. Objectives: We conducted a double-blind, placebo-controlled, randomized, dose-escalation clinical trial. This was designed to investigate both the safety and efficacy of topical salbutamol for the improvement of scar appearance when applied as a cutaneous gel to sutured wound margins on the arms of healthy volunteers. Methods: In a phase I, single-center, double-blind, placebo (vehicle) controlled, randomized, dose-escalation trial on 45 healthy human volunteers, 1 ml salbutamol topical gel was administered once daily to one 2-cm full-thickness incision site on each arm of the trial participants for 60 days. Each participant was allocated to only 1 dosing group (group 1: 2.5 mM, group 2: 5 mM, and group 3: 10 mM). Pharmacokinetic and clinical assessments of safety and efficacy were performed over a 12-month period. Scarring was assessed by validated clinical scoring systems by both investigator and participant over 12 months. Results: In healthy human volunteers, tolerability assessments indicated zero incidences of edema, exudate, bleeding, or infection at any salbutamol-treated site irrespective of dose. All participants at every time point had peak plasma levels of salbutamol below the prespecified limit of 30 ng/ml. In efficacy assessments of the scars, no statistically significant improvements were noted in the mean difference between salbutamol-treated scars at any dose compared with placebo at months 7, 9, or 12 for either the investigator or participants’ assessments. Conclusions: There are no clinically significant safety signals after the cutaneous administration of salbutamol gel (0.2–10 mM) in humans either local to the site of injury and drug administration or arising from systemic exposure to salbutamol, but the extent of salbutamol absorption decreases as the wound heals, confirming that re-epithelialization of the wound limits the potential for systemic absorption.

Limited therapies and study models hinder progress in addressing this unmet clinical need. AMA0825, a ROCK (Rho-associated protein kinase) inhibitor, has shown promising antifibrotic and antiproliferative effects in other fibrotic conditions. This study investigated the therapeutic potential of AMA0825 using in vitro, ex vivo, and a 3-dimensional spheroid model of keloid disease, which partially reflects features of the keloid microenvironment. AMA0825 demonstrated potent antiproliferative activity against keloid fibroblasts, with a half-maximal growth inhibitory concentration of 28.19 ± 1.6 nM, significantly outperforming dexamethasone (half-maximal growth inhibitory concentration = 35.35 ± 2.6 μM) and triamcinolone (half-maximal growth inhibitory concentration = 37.84 ± 3 μM). This effect was confirmed by decreased Ki-67 expression and cell cycle arrest at the G1 phase. In the 3-dimensional spheroid model, AMA0825 effectively inhibited cell proliferation at nanomolar concentrations, exceeding the efficacy of dexamethasone. Although AMA0825 did not demonstrate significant antifibrotic activity at lower concentrations, it exhibited antifibrotic effects at higher concentrations. In addition, synergistic effects were observed when combined with dexamethasone.
