Rogerio V, Rabelo V, Roschel P, Sakemi T, Germani M, Munoz-Lora VR. A novel approach for deoxycholic acid administration to treat submental fullness: A case report assessed by 3D stereophotogrammetry. J Oral Biol Craniofac Res 2024; 14:280-283. [PMID: 38586285 PMCID: PMC10998212 DOI: 10.1016/j.jobcr.2024.03.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 03/11/2024] [Accepted: 03/21/2024] [Indexed: 04/09/2024] Open
Abstract
Background While effective, DAc injections for submental fat (SMF) reduction carry risks, including vascular damage and skin necrosis when improperly administered. This study presents a novel approach to SMF reduction using blunt microcannulas for DAc injections, coupled with 3D stereophotogrammetry quantification (3D-SQ). Clinical presentation A 47-year-old female with SMF underwent two DAc applications. 3D-SQ was performed before and after each treatment using a 3D-SQ system. The patient experienced a substantial total volume reduction of 14.81 mL in the submental area after two DAc applications. 3D-SQ analysis showed a gradual reduction in submental volume over time. Importantly, no serious adverse events were reported, with only minor pain and warmth at the treated site. The reduction of SMF through DAc injections involves adipocyte cell lysis, emphasizing the importance of proper injection technique to avoid adverse events. The use of blunt microcannulas offers a safer alternative, minimizing the risk of skin necrosis, ulceration, and intra-arterial injections. Additionally, cannulas reduce bruising due to their blunt design and fan technique, enhancing patient comfort and safety. Conclusion This case report highlights the efficacy of a novel cannula approach for DAc SMF reduction, assessed by 3D-SQ. Blunt microcannulas may represent a safer option compared to hypodermic needles, reducing the likelihood of severe complications.

Efficacy and safety of the enzymatic mixture - Lipase, collagenase and hyaluronidase - In the treatment of moderate to severe submental fat: A prospective cohort study. Heliyon 2024; 10:e25759. [PMID: 38375282 PMCID: PMC10875420 DOI: 10.1016/j.heliyon.2024.e25759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 01/30/2024] [Accepted: 02/01/2024] [Indexed: 02/21/2024] Open
Abstract
Purpose To study the effect of the enzymatic mixture: Lipase, Collagenase and Hyaluronidase in the treatment of submental fat. Methods A monocentric prospective cohort study including 10 female patients, aged between 18 and 65 years old, who received treatment for submental fat with a mixture of Lipase, Collagenase, and Hyaluronidase. The treatment protocol consisted of one treatment session every 21 days for a total of 3 sessions. In each session, 4 ml of the enzymatic mixture (1 ml of Collagenase GH PB20, 1 ml of Hyaluronidase PB 3000 and 2 ml of Lipase PB 500) + 2 ml of Lidocaine 2% were injected in the submental fat (SMF). Efficacy was assessed four weeks after the last session. Co-Primary Outcome was defined as the improvement of ≥ 1-point in Clinician-Reported and Patient-Reported Sub-mental Fat Rating Scales (CR-SMFRS and PR-SMFRS). Secondary Outcomes included score reductions in Patient-Reported Sub-mental Fat Impact Scale (PR-SMFIS), ≥10% reduction in submental fat pad thickness by ultrasound, and Subject Self-Rating Scale (SSRS) responses of 4, 5, or 6. Results The Co-Primary outcome was achieved in 9 out of 10 patients. A considerable reduction of 22.8% in the PR-SMFIS was observed. Furthermore, 9 out of 10 patients expressed overall satisfaction with the treatment. Submental fat reduction of more than 10% was observed in 9 out of 10 patients in neutral position and in all patients in flexed position. Adverse effects were only limited to local reactions. Conclusion The enzymatic mixture of Lipase, Collagenase and Hyaluronidase is an effective and safe minimally-invasive method for the reduction of SMF that can be used alone or in conjunction with other treatment modalities.

Abstract
RESULT The review delves into the realm of reducing submental fat, presenting a comprehensive analysis of various lipolytic agents used in plastic surgery and dermatology. The introduction establishes the context by defining the key indicators of a youthful neck and emphasizing the significant influence of fat in the aging process, particularly in the submental area. The usage of aminophylline involves subcutaneous injections, facilitating fat breakdown by increasing cyclic adenosine monophosphate and inhibiting adenosine receptors. Hypotonic pharmacologic lipo-dissolution induces fat dissolution via injected compounds under pressure, while lipolytic lymphatic drainage employs hyaluronidase to reduce tissue viscosity, aiding fat circulation. Glycerophosphorylcholine containing choline alfoscerate claims to activate fat metabolism, whereas the utilization of phosphatidylcholine combined with deoxycholate lacks cosmetic approval due to safety concerns. Deoxycholic acid has FDA approval for submental fat reduction, yet its mechanisms remain incompletely understood. Understanding the complex anatomy and mechanisms of lipolytic agents is essential for safe and effective submental fat reduction, despite evolving practices and off-label utilization. Clinical guidelines and references support this discussion, offering insights for safer applications.

Efficacy, safety, and potential industry bias in using deoxycholic acid for submental fat reduction ‒ A systematic review and meta-analysis of randomized clinical trials. Clinics (Sao Paulo) 2023; 78:100220. [PMID: 37806137 PMCID: PMC10570630 DOI: 10.1016/j.clinsp.2023.100220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 04/30/2023] [Accepted: 05/12/2023] [Indexed: 10/10/2023] Open
Abstract
Lipolytic substance injections to reduce localized fat have been extensively used because it is a low-invasive method. This review aimed to evaluate the efficacy and safety of deoxycholic acid in submental fat reduction compared to a placebo and investigate the potential industry sponsorship bias in the results of randomized clinical trials on this topic. Ten electronic databases were extensively searched for randomized clinical trials without restriction on language and year of publication. Two reviewers extracted the data and assessed the individual risk of bias in the studies with the RoB 2.0 tool. The industry sponsorship bias was evaluated according to citations in the articles regarding industry funding/sponsorship throughout the texts. Fixed and random effects meta-analyses were performed, and the results were reported in Risk Ratio (RR) at a 95% Confidence Interval (95% CI). The initial search provided 5756 results, of which only five were included. Only two studies had a low risk of bias. All studies showed a potential industry bias. The meta-analysis showed that patients treated with deoxycholic acid had significant positive results for all efficacy outcomes and a higher risk of fibrosis, pain, erythema, numbness, swelling, edema, pruritus, nodules, headache, and paresthesia. The low to moderate certainty of evidence found allows concluding that deoxycholic acid is effective in submental fat reduction, causing well-tolerated adverse effects. However, all eligible studies showed a potential industry bias.

Abstract
Submental fat (SMF) contributes to an aged or overweight appearance that may negatively impact an individual's psychological well-being. Deoxycholic acid (ATX-101) is an injectable formulation of deoxycholic acid approved to treat SMF. The Condition of Submental Fullness and Treatment Outcomes Registry (CONTOUR) Australia study was designed to understand treatment patterns and outcomes with ATX-101 in Australia. Methods CONTOUR Australia was a phase 4, prospective, observational, multicenter registry that enrolled adults considering treatment for SMF reduction. Results The registry enrolled 86 patients from six sites. Significant changes from baseline through the end of treatment indicated improvement in mild to moderate fullness associated with SMF on the Clinician-Reported SMF Rating Scale and the Patient-Reported SMF Rating Scale, improvement in SMF-associated psychological impact after treatment on the Patient-Reported SMF Impact Scale, no overall worsening in skin laxity based on Submental Skin Laxity Grade, and increased patient satisfaction with the face/chin on the Subject Self-Rating Scale after receiving treatment. Adverse events were all mild and mostly related to the injection site (ie, bruising and swelling). Conclusion CONTOUR Australia observed clinically meaningful and significant outcomes and further supports ATX-101 as a well-tolerated and effective treatment for SMF reduction.

Abstract
BACKGROUND The role of ATX-101 in submental fat reduction has been well documented; however, its applicability across multiple anatomic areas is to be explored. OBJECTIVES The authors sought to describe the experience with ATX-101 subcutaneous injections for body and jawline contouring and evaluate its safety. METHODS This single-arm, single-center observational study included 201 patients who underwent injection adipocytolysis with ATX-101 (area-adjusted dose of 2 mg/cm2) in the jowl, abdomen (upper/lower), thigh (inner/outer/banana roll), arm, anterior periaxillary fat, back (lower/upper/nape/lipoma), knee (anterior/medial), chest, and/or neck. The number of treatment sessions, treatment volumes, doses, injections required for each anatomic area, and associated adverse events were recorded. RESULTS The mean number of treatment sessions conducted was 1.8. Multiple sessions were common for the jowl (mean: 2.0 and mean volume administered varied significantly between persons receiving 1 or multiple sessions [P = 0.005]). The mean volume and mean number of injections per session were highest in the chest (84.7 mL and 423.5, respectively) and lowest in the jowl (0.8 mL and 4.6, respectively). The chest (0.2 mL) and nape (0.2 mL) received the highest mean ATX-101 dose per injection site per session, whereas the inner thigh (0.11 mL) and upper back (0.11 mL) received the least. Adverse events observed were localized to the injection site. All patients experienced edema after each session, whereas numbness, tenderness, bruising, and paresis were experienced by 99.6%, 94.2%, 33.1%, and 2.6% of patients, respectively. Alopecia was not observed. CONCLUSIONS ATX-101 was well tolerated for body and jawline contouring. LEVEL OF EVIDENCE: 4

Abstract
Deoxycholic acid (DCA) is a bile acid capable of forming micelles and modifying the properties of hydrogels. We incorporated DCA in sodium alginate (SA) and poloxamer 407 matrices creating novel DCA-copolymer hydrogel for therapeutic delivery. Hydrogels were assessed for common rheological properties. Biocompatibility and biological effect were examined on various cell lines. Cell viability was determent in normal and various hypoxic conditions, and full mitochondrial bioenergetic parameters were assessed in cell lines in order to illustrate hydrogel effects on survival, and cell metabolic profile within the hydrogels. Obtained data suggest that a low dose of DCA in permeable, biocompatible hydrogels can be beneficial for cells to combat hypoxic conditions.

Abstract
BACKGROUND CBL-514 is a novel injectable drug that may be safe and efficacious for localized abdominal subcutaneous fat reduction. OBJECTIVES The aim of this study was to assess the safety and efficacy of CBL-514 in reducing abdominal subcutaneous fat volume and thickness. METHODS This Phase IIa, open-label, random allocation study consisted of a 6-week treatment period and follow-up at 4 and 8 weeks following the last treatment. Participants were randomly allocated to receive 1.2 mg/cm2 (180 mg), 1.6 mg/cm2 (240 mg), or 2.0 mg/cm2 (300 mg) of CBL-514 with up to 4 treatments, each comprising 60 injections into the abdominal adipose layer. Changes in abdominal subcutaneous fat were assessed by ultrasound at follow-up visits. Treatment-emergent adverse events were recorded. RESULTS Higher doses of CBL-514 (unit dose, 2.0 and 1.6 mg/cm2) significantly improved the absolute and percentage reduction in abdominal fat volume (P < 0.00001) and thickness (P < 0.0001) compared with baseline. Although the COVID-19 pandemic halted some participant recruitment and follow-ups, analysis was unaffected, even after sample size limitations. CONCLUSIONS CBL-514 injection at multiple doses up to 300 mg with a unit dose of 2.0 mg/cm2 is safe, well-tolerated, and reduced abdominal fat volume and thickness by inducing adipocyte apoptosis. Although other procedures exist to treat abdominal fat, they have limitations and may cause complications. At a dose of 2.0 mg/cm2, CBL-514 safely and significantly reduced abdominal fat volume by 24.96%, making it a promising new treatment for routine, nonsurgical abdominal fat reduction in dermatologic clinics.

Abstract
ATX-101 is an injectable, synthetically derived formulation of deoxycholic acid used for submental fat reduction. Methods A narrative review of references relevant to the mechanism of action of ATX-101 and its relationship to efficacy and inflammatory adverse events was conducted. Results When injected into subcutaneous fat, deoxycholic acid physically disrupts adipocyte cell membranes, leading to local adipocytolysis, cell death, and a mild, local inflammatory reaction consisting of macrophage infiltration and fibroblast recruitment. At Day 28 postinjection, inflammation largely resolves, and key histologic features include fibrotic septal thickening, neovascularization, and atrophy of fat lobules. Based on the mechanism of action of ATX-101 and the demonstrated inflammatory response, localized inflammation and swelling are expected following treatment. Indeed, postinjection swelling and other local injection-site events, including pain, erythema, and bruising, are common during and after treatment. Because of inflammatory sequelae following injection, reduction in submental fat is gradual and may require months before the full response is apparent. Patients may also require multiple treatment sessions to achieve their treatment goals. Repeated treatments may result in less pain and swelling over time owing to a combination of factors, including less target tissue allowing for lower doses/injection volumes, persistent numbness, and greater tissue integrity from thickened fibrous septa. Conclusions Physicians can manage expectations by counseling patients that, based on the mechanism of action of ATX-101 and data from pivotal clinical trials, ATX-101 treatment results in localized inflammation/swelling and gradual submental fat reduction. Patient education about common local adverse events is critical.

Abstract
OBJECTIVES A review of new drug approvals (NDAs) by the US Food and Drug Administration (FDA) for 2006 to 2015 showed that approximately 20% of new drugs had labeling based on patient-reported outcomes (PROs). The purpose of this study was to review labeling text based on PRO endpoints for NDAs from 2016 to 2020, with a special focus on the comprehensibility of such statements when included. METHODS We reviewed drug approval reports on the Drugs@FDA web page of the FDA website to determine the number of NDAs from 2016 to 2020. For all identified NDAs, drug approval package and product labels were reviewed. NDAs from 2016 to 2020 were grouped by disease category as per International Classification of Diseases 10th Revision. Data were summarized for diseases that traditionally rely on PROs for evaluating treatment benefit (PRO dependent) and for diseases that traditionally do not rely on PROs (non-PRO dependent). Results were compared with NDAs from 2006 to 2010. RESULTS NDAs amounting to 228 were identified from 2016 to 2020, 26.3% of which had labeling statements based on PRO endpoints. From 2006 to 2015 and from 2016 to 2020, PRO labeling statements were included in 46.5% (46 of 99) and 50.0% (47 of 94), respectively, of NDAs for PRO-dependent new molecular entities and in 6.0% (12 of 199) and 9.7% (13 of 199), respectively, of NDAs for non-PRO-dependent new molecular entities. Comprehensibility of labeling statements based on PRO endpoints was judged to be complex in 56.7% of product labels. CONCLUSIONS The increase in labeling text based on PRO endpoints in product labels is encouraging. However, there is room for improvement on the comprehensibility of labeling statements based on PRO endpoints.

Oh SM, Kim BC, Hong GW, Jung W. Changes in the neck tissue layers during pinch manipulation: Implications for lipolytic deoxycholate injections for double chin. J Cosmet Dermatol 2022; 21:3754-3758. [PMID: 35041769 DOI: 10.1111/jocd.14696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Accepted: 10/11/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND The skin of the neck is often pinched during minimally invasive esthetic procedures for the double chin using a lipolytic agent in order to facilitate injecting into the subcutaneous fat layer rather than under the platysma muscle. However, how the neck tissue layers move during the pinch manipulation is not well understood. AIMS To determine which layer of the neck is lifted during pinching and to evaluate the usefulness of the pinch manipulation during injection therapy. METHODS The pinched submentum of a living person was scanned using MRI, and ultrasonography was also performed in the same area in both resting and pressed states. At four sites on a fresh cadaver, the skin of the neck was pinched and the elevated neck skin was excised. The exposed areas were grossly examined. RESULTS MRI scanning revealed that the pinch manipulation extended the subcutaneous fat layer and moved the platysma muscle to a deeper location. Ultrasonography revealed that the thickness of each layer of the neck was reduced when pressing the neck. In the cadaver examination, pinching resulted in part of the subcutaneous fat lifting, and this was removed when the lifted skin was cut, leaving the platysma muscle intact. CONCLUSIONS When performing an esthetic procedure that involves injecting a lipolytic agent into the submental area, the pinch manipulation is a very useful technique for ensuring a safe procedure that avoids injecting into the deep layer under the platysma muscle.

Abstract
BACKGROUND Unwanted submental fat (SMF) is aesthetically unappealing, but methods of reduction are either invasive or lack evidence of their use. OBJECTIVE The authors sought to evaluate the safety and efficacy of a novel triple-layer high-intensity focused ultrasound (HIFU) regimen for SMF reduction. METHODS Forty Korean subjects with moderate/severe SMF were evaluated after receiving a session of triple-layer HIFU treatments (using 3.0-, 4.5-, and 6.0-mm focusing transducers). The objective evaluation based on the 5-point Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) and patients' satisfaction based on the 7-point Subject Self-Rating Scale (SSRS) were determined 8 weeks after treatment. Three-dimensional image analysis was also performed. RESULTS At the follow-up visit, the proportion of treatment responders defined as subjects with ≥1-point improvement in CR-SMFRS was 62.5%, and the proportion of patients satisfied with appearance of their face and chin (score ≥4 on the SSRS) was 67.5% of the total patients. The results of 3-dimensional analysis were consistent with clinical observations. Only mild and transient side effects were observed for some patients with no serious adverse effects. CONCLUSION The triple-layer HIFU regimen including the novel 6.0-mm transducer has benefits for tightening and rejuvenation of the area with unwanted SMF, showing reasonable safety profiles.

Abstract
BACKGROUND Beyond submental fat reduction, injectable deoxycholic acid (DCA) has gained popularity in recent years for various minimally invasive lipolysis applications. OBJECTIVE To summarize and evaluate the evidence of off-label uses of injectable DCA. METHODS MEDLINE, Embase, CINAHL, Web of Science, and CENTRAL were searched. The outcomes measured included applications of DCA, treatment regimen, and its efficacy. An overall success rate for each condition was calculated based on the improvement defined in the included studies. RESULTS Eleven studies evaluated the cosmetic use of DCA for excess adipose tissue on various anatomical locations. The outcomes were evaluated at time points ranging from 1 to 21 months post-treatment, with overall success rates over 85%. Eight case reports and series reported the success of using DCA treating lipomas, xanthelasmas, paradoxical adipose hyperplasia, fibrofatty residue of infantile hemangioma, piezogenic pedal papules, and HIV-associated lipohypertrophy. Although the preliminary efficacies were high, the overall recommendations for off-label uses are weak because of the lack of high-level studies. CONCLUSION The review emphasizes the diversity of injectable DCA as a minimally invasive technique for lipolysis. Further high-level studies demonstrating consistent treatment regimens and methods of evaluation are warranted to make more definitive recommendations regarding off-label DCA use.

Abstract
BACKGROUND ATX-101 (deoxycholic acid) significantly reduced submental fat (SMF) severity in two 24-week Phase 3 studies (REFINE-1 and REFINE-2). OBJECTIVES The aim of this study was to evaluate the durability of effect and long-term safety of ATX-101. METHODS REFINE study patients who maintained ≥1-grade improvement on the Clinician-Reported SMF Rating Scale (CR-1 responders) 12 weeks after their last REFINE treatment were eligible for enrollment in this multicenter, double-blind, nontreatment, long-term, follow-up study (NCT02163902). The primary endpoint was CR-1 response at Years 1, 2, and 3. Patient-reported satisfaction, psychological impact, and adverse events were monitored. RESULTS In total, 224 patients (ATX-101, n = 113; placebo, n = 111) were enrolled. Maintenance of CR-1 response was significantly better in the ATX-101 group than in the placebo group at Year 1 (86.4% vs 56.8%; P < 0.001), Year 2 (90.6% vs 73.8%; P = 0.014), and Year 3 (82.4% vs 65.0%; P = 0.03). Most (74%) ATX-101‒treated patients satisfied at 12 weeks remained satisfied at Year 3. Significant reductions from baseline in psychological impact scores were sustained through Year 3 (P < 0.001). No new treatment-related adverse events were reported. CONCLUSIONS Improvements in submental contour achieved with ATX-101 are maintained for 3 years in most patients. No new safety signals emerged.

Abstract
BACKGROUND Although deoxycholic acid (DCA) has been proposed for use in other areas, it is used primarily for treating moderate-to-severe fat in the submental area. OBJECTIVE To evaluate the safety and efficacy of DCA for fat reduction in the hypogastric region. MATERIALS AND METHODS A prospective, longitudinal, nonrandomized, open-label, interventional pilot study was performed. Deoxycholic acid was transcutaneously injected in upper right, upper left, lower right, and lower left hypogastric zones. Fat thickness was assessed using calipers, ultrasound, and 3-dimensional scanning. The primary end point safety was evaluated by laboratory tests and the incidence of adverse events. RESULTS Fourteen patients (54 treatment sessions) were included. The mean total volume administered was 26.6 mL. The main local adverse events were edema (94.4%), bruising (90.7%), and erythema (79.6%), all being self-limited (the mean duration 9.6, 7, and 2 days, respectively). A DCA dose was significantly associated with erythema duration (p = .0421) but not with edema duration (p = .1611) or bruising incidence (p = .1013). Measurement using calipers, ultrasound, and 3-dimensional scanning revealed significant fat thickness reduction. Patient-reported outcome measure scores revealed a significant improvement in patient satisfaction. CONCLUSION Deoxycholic acid may be a safe and effective option for reducing fat thickness in the hypogastric region, although given the cost/benefit ratio probably should be reserved for small deposits.

Abstract
BACKGROUND ATX-101 is indicated for submental fat treatment. OBJECTIVE Evaluate ATX-101 versus placebo for reducing submental fat. MATERIALS AND METHODS Adults with unwanted submental fat across 6 global sites were randomized to ATX-101 (0.5%, 1.0%, or 2.0%) or placebo for ≤4 treatments every 28 days. Outcomes included safety (adverse events and pain visual analog scale) throughout the study and efficacy (submental fat rating, patient satisfaction, and submental fat improvements) at Week 16. RESULTS Eighty-four of 85 enrolled patients received ≥1 ATX-101 treatment (0.5% [n = 20], 1.0% [n = 20], 2.0% [n = 22] or placebo [n = 22]). Most patients (n = 82) experienced adverse events, which were mostly mild/moderate, seemed to be dose-related, and led to no study discontinuations. The mean pain scores were highest in the ATX-101 1.0% and 2.0% groups. Week-16 change from baseline in the submental fat rating scale was significantly greater for ATX-101 0.5% and 1.0% versus placebo (p ≤ .05). At Week 16, 71%, 74%, 53%, and 40% of patients in the ATX-101 0.5%, 1.0%, 2.0%, and placebo groups, respectively, achieved a ≥1-grade reduction in submental fat from baseline. Satisfaction with appearance and patient-assessed global improvement ratings increased in all ATX-101 treatment groups versus placebo. CONCLUSION All ATX-101 concentrations were safe and efficacious for moderate/severe submental fat reduction.

Abstract
BACKGROUND No validated assessment tools are available to evaluate patient-reported outcomes specifically related to submental fat (SMF). OBJECTIVE To develop and validate scales measuring the severity (Patient-Reported SMF Rating Scale [PR-SMFRS]) and psychological impact (Patient-Reported SMF Impact Scale [PR-SMFIS]) of SMF. MATERIALS AND METHODS A literature review, content validation interviews (concept elicitation [n = 29] and cognitive debriefing [n = 15]) in adults with SMF, and expert interviews (n = 3) were conducted to develop the PR-SMFRS and PR-SMFIS. Psychometric validity (acceptability, reliability, and validity) for the PR-SMFRS and PR-SMFIS was assessed using data from 1 phase 2 and 5 phase 3 ATX-101 studies in patients with excess SMF. RESULTS The PR-SMFRS was constructed as a single-item, 5-point rating of the SMF amount/size. The PR-SMFIS was constructed as a 6-item scale, with an 11-point numeric rating for each item. Both scales demonstrated acceptable psychometric properties (test-retest reliability and internal consistency). The anchor-based minimally important difference analysis suggests a 1-point improvement on the PR-SMFRS (scale of 0‒4) and a 3-point improvement on the PR-SMFIS (scale of 0‒10) represent clinically meaningful change. CONCLUSION The PR-SMFRS and PR-SMFIS are reliable, valid instruments for assessing the severity and psychosocial impact, respectively, of SMF and detecting clinically meaningful change with intervention.

Abstract
Objective: To investigate the efficacy and safety of deoxycholic acid (DOC) for SMF reduction.Methods: We conducted a systematic review and meta-analysis of randomized controlled trials. We searched PubMed/MEDLINE, EMBASE, and Cochrane databases until June 2020. Efficacy outcomes: Clinician-Reported Submental Fat Rating Scale; Patient-Reported Submental Fat Rating Scale; Subject Self-Rating Scale; SMF reduction measured using caliper and resonance magnetic imaging; Early therapeutic success. Safety outcomes: Withdrawals due to adverse events (AEs), Rates of AEs, Skin laxity.Results: Five studies were included, comprising 1,838 participants. DOC (1 or 2 mg/cm2) had greater improvement in all efficacy measures compared to placebo. No differences were seen between both doses of DOC. Withdrawals due to AEs were low with 1 and 2 mg/cm2 of DOC (6.8% vs. 9.9%, respectively), and there was no difference between the two doses (p = 0.22). AEs were usually associated with the injection site, were predominantly transient, and commonly resolved within the treatment session interval. Injection site pain, hematoma, anesthesia/numbness, erythema, and swelling/edema were the most common AEs. There was no difference in their prevalence between both doses of DOC.Conclusions: DOC is effective and safe for SMF reduction with no differences between doses of 1 and 2 mg/cm2.

Abstract
BACKGROUND Submental fat (SMF) can negatively affect perceptions of health and attractiveness. The Condition of Submental Fullness and Treatment Outcomes Registry (CONTOUR) was designed to understand SMF treatment in clinical practice. OBJECTIVE To report efficacy, treatment characteristics, and safety associated with real-world use of ATX-101 (deoxycholic acid injection). METHODS CONTOUR enrolled adults considering treatment for SMF reduction. ATX-101-treated patients who completed the end-of-treatment questionnaire were divided into those who ended treatment because they met their treatment goals (n = 197) and those who did not (n = 196). RESULTS Patients who met their goals (a more defined jawline, looking younger, and looking thinner) were more likely to have less SMF at baseline and to receive ≥2 ATX-101 treatments. More patients who met their goals achieved clinically meaningful reduction in SMF and reported increased satisfaction with their appearance (90% vs 57%). Moderate and severe patients' ATX-101 volume was similar for both those who met goals and those who did not, but extreme patients who met their goals required 10 mL more than those patients who did not. CONCLUSION Careful patient selection, adequate volume administration, and an appropriate number of treatments (dependent on baseline SMF severity) contribute to successful outcomes with ATX-101.

Abstract
Deoxycholic acid (BELKYRATM, Allergan, Markham, ON, Canada) is a minimally invasive injectable treatment approved by Health Canada for the nonsurgical reduction of submental fullness. Multiple phase III clinical trials have proven the efficacy and safety of deoxycholic acid. In the clinical trials, the most common adverse events (AEs) reported, such as injection site pain, numbness, swelling, bruising and induration, were transient and mild-to-moderate in severity. Additional postmarketing AEs have been reported in the literature. In this study, we reviewed the uncommon reported events and aimed to increase clinician awareness of the potential adverse effects for patient counselling of risks and benefits, identify AEs of procedures that may be performed outside of the medical environment, and identify factors that increase the risk of an adverse event. Beyond the clinical trials, real-world case reports and case series have been reported for the AEs of alopecia, transient neuropraxia, vascular occlusive events/vascular injury, and skin necrosis. Dermatologists need to be aware of these risks, for the treatment and management of their own patients and for those patients who may be treated outside the medical clinic environment that present for medical management of these AEs.

Abstract
BACKGROUND ATX-101 is approved for submental fat reduction. OBJECTIVE To characterize the histological effect of ATX-101 injection into subcutaneous fat. METHODS This Phase 1 open-label study enrolled 14 adults to receive injections of ATX-101 into abdominal fat at varying concentrations (0.5%, 1.0%, 2.0%, or 4.0%), volumes (0.2 or 0.4 mL), spacing (0.7, 1.0, or 1.5 cm), and time points before scheduled abdominoplasty (1, 3, 7, or 28 days). During abdominoplasty, tissue was excised and preserved for histology. RESULTS All injection paradigms resulted in histological changes confined to the subcutaneous layer, which were more prominent at higher concentrations and independent of volume and spacing. Key features at Day 1 after injection were adipocytolysis, blood vessel injury, neutrophilic inflammation, and lysis of locally present neutrophils. At Day 3, inflammation was reduced versus Day 1, and hemorrhage and lipid lake formation (at higher concentrations) were observed. Day 7 samples exhibited prominent adipocytolysis, mild inflammation, lipid-laden macrophages in the septae, and repair of vascular injury. At Day 28, inflammation was largely resolved and prominent features were septal thickening, neovascularization, and atrophy of fat lobules. CONCLUSION Subcutaneous injection of ATX-101 induces adipocytolysis and local inflammation with septal thickening and resolution of inflammation by 28 days after injection.

Abstract
BACKGROUND The study proposes a novel protocol for targeting the jowls using deoxycholic acid (DCA) injections, with emphasis on safety and feasibility of the procedure. METHODS This prospective study was conducted at a cosmetic practice between June 2016 and May 2017. Twelve consecutive patients seeking reduction/improvement in mild/moderate jowl fat were injected with DCA subcutaneously in a predefined circular area 1.0 cm above the mandibular border. Treatment response was assessed using physician-evaluated Global Aesthetic Improvement Scale (GAIS) and Subject GAIS. RESULTS Twelve patients (11 women and 1 man) with mild (n = 8) or moderate (n = 4) jowls were treated. After the first treatment, GAIS responses for 24 jowls showed 5 jowls with vast improvement, 15 with moderate improvement, and 4 with no change. After the second session for 5 jowls in 3 patients, GAIS responses showed vast improvement in 4 jowls and moderate improvement in 1. Adverse events included induration (n = 4), bruising (n = 6), numbness (n = 2), pain (n = 5), redness (n = 3), edema (n = 9), and dysphagia (n = 1). CONCLUSION Results of this early experience showed that DCA injections were safe and effective for nonsurgical jowl reduction.

Abstract
BACKGROUND The principal current treatment options for reduction of excess anterior periaxillary fat (APAF) are invasive procedures such as excision and liposuction. OBJECTIVES The aim of this study was to evaluate the efficacy and safety of ATX-101 (deoxycholic acid injection) as a treatment to reduce APAF. METHODS In this retrospective study, 12 women with periaxillary fullness underwent ATX-101 treatment. Patients were examined to confirm that fullness was due to excess APAF and sufficient subcutaneous fat was present to warrant treatment. Before treatment, the lateral and medial borders of the treatment area were identified and marked. A 1-cm grid was placed to guide the placement of the ATX-101 injections. Reduction in APAF was based on visual assessment and palpation by the clinician, and assessment of before/after patient photographs by the patient and 2 blinded plastic surgeons; all had to agree that APAF reduction had occurred. Patient satisfaction was also assessed. Safety was evaluated in terms of adverse events (AEs). RESULTS Patients underwent a mean of 1.8 ATX-101 treatments; 5 patients received 1 treatment, whereas 7 received multiple treatments. Ten patients achieved a reduction in APAF and were satisfied with treatment. One patient was satisfied after 1 treatment but did not return for posttreatment photographs. One patient did not show any noticeable reduction in APAF after 1 treatment; however, this patient was satisfied and additional treatments are planned. Common AEs included injection-site numbness, edema, and tenderness that lasted for a mean of 18.6, 6.0, and 4.5 days, respectively. CONCLUSIONS ATX-101 effectively reduced APAF and was generally well tolerated in this small cohort. Larger prospective studies are needed to confirm these findings. LEVEL OF EVIDENCE: 4

Abstract
Importance Since its approval by the US Food and Drug Administration for treatment of moderate to severe submental liposis in April 2015, deoxycholic acid (Kybella) has received significant media attention as a novel aesthetic treatment. Four phase 3 clinical trials have published data demonstrating the safety and efficacy of the drug compared with placebo; however, no study has juxtaposed the product with submental liposuction. Objective To evaluate the efficacy of injectable deoxycholic acid in the treatment of isolated submental liposis. Evidence Review A pooled analysis of the data from the 2 European and 2 North American phase 3 clinical trials was performed by grouping the study participants by treatment arm to analyze efficacy, adverse effects, and treatment variables. Members of the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) were also surveyed regarding their clinical use of deoxycholic acid, fees, and adverse events. Findings The pooled analysis included 1738 unique patients (348 men [20.0%] and 1390 women [80.0%]; mean [SD] age, 47.7 [1.6] years) and revealed that all studies demonstrated efficacy compared with placebo. However, a significant number of patients experienced pain, edema, and numbness after injection. The clinical trial population was injected with a mean (SD) of 186.0 (106.6) mg of drug per patient during the course of treatment. A total of 102 members responded to the survey, representing 4% of AAFPRS membership. Based on the results of the survey, clinicians reported charging a mean (SD) of $691.04 ($168.68) per 20-mg vial of deoxycholic acid, resulting in a cost of $6426.35 per study participant. The survey revealed a mean (SD) total cost to the patient for submental liposuction to be $2976.56 ($1041.62). Conclusions and Relevance Although the clinical trials demonstrated functional drug efficacy, the large volume of drug used precluded cost-effectiveness. The survey found clinical practice to differ from the protocols used in the trials. Deoxycholic acid may be only fiscally efficacious for patients with mild to moderate submental liposis who require only 20 to 30 mg of drug per treatment for 3 treatment sessions. Level of Evidence 1.

Abstract
BACKGROUND Transgender patients may seek nonsurgical methods for facial masculinization and feminization as an adjunct or alternative to undergoing surgical procedures. OBJECTIVES The authors reviewed the existing literature regarding this topic and provided an overview of nonsurgical techniques for facial masculinization and feminization. METHODS A comprehensive literature search of the PubMed and MedLine databases was conducted for studies published through December 2017 for techniques and outcomes of nonsurgical facial masculinization and feminization. Keywords were used in performing the search. Data on techniques, outcomes, complications, and patient satisfaction were collected. RESULTS Four articles fit our inclusion criteria. Given the lack of published literature describing facial injectables in transgender patients, data from the literature describing techniques in cisgender patients were utilized to supplement our review. CONCLUSIONS Facial feminization can be achieved through injectables such as neurotoxin and fillers for lateral brow elevation, lip augmentation, malar augmentation, and improvement of rhytids. Facial masculinization can be achieved with injectables used for genioplasty, jawline augmentation, and supraorbital ridge augmentation. One must develop best practices for these techniques in the transgender patient population and increase awareness regarding nonsurgical options. LEVEL OF EVIDENCE: 4

Abstract
Supplemental Digital Content is Available in the Text. BACKGROUND Satisfaction with discrete facial areas influences self-perceptions of attractiveness, self-esteem, and quality of life. Currently, there is a lack of understanding of how the submental area impacts feelings and behaviors. OBJECTIVE To characterize the effects of submental fat (SMF) on feelings/emotions and actions/behavior among adults in the United States. METHODS Online health-based surveys recruited approximately 400 adults (18–65 years) in each of 5 categories based on the respondent's assessment of their SMF. Respondents either agreed or disagreed with 17 statements regarding their feelings/emotions and actions/behaviors related to the area underneath their chin. RESULTS Overall, 1996 respondents were included (equal distribution of males/females; mean age, 41.9 years). Even a slight amount of chin fat was associated with negative feelings and behaviors. As SMF increased, so did the number of respondents reporting negative self-perceptions such as being embarrassed by the area under their chin. In general, a greater percentage of female compared with male respondents reported negative feelings and behavioral changes due to their submental area. CONCLUSION Excess SMF can have a substantial negative effect on a person's feelings of attractiveness and behaviors. Reduction of SMF may not only improve one's appearance, but also may enhance one's self-esteem.

Evaluation of Safe and Effectiveness of an Injectable Solution Acid Deoxycholic Based for Reduction of Localized Adiposities. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2018; 6:e1794. [PMID: 30276043 PMCID: PMC6157955 DOI: 10.1097/gox.0000000000001794] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Accepted: 04/03/2018] [Indexed: 11/25/2022]
Abstract
Background: The use of deoxycholic acid to reduce localized fat deposits is a procedure that has been in use for about 30 years. Its effectiveness as treatment is due to emulsification of phospholipids and therefore, solubilization of the biological membranes with resulting fat necrosis. The purpose of the study was to assess the effectiveness and the safety of an injectable solution containing sodium deoxycholtate 1.25% (DB125), used as intralipotherapy. Methods: The effectiveness and safety of DB125 solution have been assessed with a multicentre observational prospective study carried out between February and October 2017. The 221 selected patients presented with various forms and degrees of localized fat in several areas. Intralipotherapy treatments were performed 6 weeks apart and until the clinical result was obtained. Aesthetic outcomes were evaluated by the authors using preoperative and postoperative photographic documentation and by the patients with their level of satisfaction by filling out an anonymous form. Major adverse events were reported by each doctor who performed the treatment. Results: Two hundred twenty-one patients treated in 273 cases of different localized fat deposits. One hundred eighty-five patients who could be assessed for final results gave the effectiveness of the treatment an average score of 7.4. The failure percentage of the treatment was 3.8%. The medical evaluation showed treatment success in 93.5% of cases. Adverse events can be divided into 2 groups: minor adverse events, which are very frequent and major ones, which are extremely rare. For both groups, the adverse events can be ascribed to localized problems in the treatment area. Conclusion: Studies have shown that the second-generation solution containing sodium deoxycholate 1.25% is effective and safe to treat different localized fat deposits. The high degree of effectiveness shown in the study was not associated with a lesser degree of handling because, at the doses indicated and with the use of intralipotherapy, the occurrence of adverse events was minimal.

Abstract
Aesthetic dermatology (AD) is a rapidly growing subspecialty of dermatology. The acceptance of AD in scientific community and the society is associated with its competence, efficiency, and seriousness. This review highlights some recent developments toward new tools, techniques, and understanding in the field of AD. Analyzing the specific needs of patients and assessing the effect by objective measurements is important for further progress. For long time ignored, white adipose tissue has gained increasing interest in biology and rejuvenation. Characterization of dermal and subcutaneous white adipose tissue has made progress. The interaction of hyaluronic acid and calcium hydroxyl apatite (CaHA) fillers with adipocytes could be responsible for clinical efficacy. New developments of oral collagen treatment and highly diluted CaHA to contour the body outside the face will be discussed. Submental contouring using purified desoxycholic acid is another new development.

Abstract
BACKGROUND Bile acids play important roles in cholesterol metabolism and signal through farnesoid X receptor and G protein-coupled receptors. Given their importance in liver biology, bile acid therapy enables therapeutic applications beyond the treatment of cholestatic liver disease. However, predicting hepatotoxicity of bile acids in humans is obscured due to inconsistent extrapolations of animal data to humans. AIM To review the evidence that could explain discordant bile acids hepatotoxicity observed in humans and animals. METHOD Literature search was conducted in PubMed using keywords "bile acid," "transporter," "hepatotoxicity," "clinical study," "animal study," "species difference," "mechanism," "genetic disorder." Relevant articles were selected for review. RESULTS Clinically significant hepatotoxicity was reported in response to certain bile acids, namely chenodeoxycholic acid, which was given a boxed warning for potential hepatotoxicity. The chemical structure, specifically the number and orientation of hydroxyl groups, significantly affects their hydrophobicity, an important factor in bile acid toxicity. Experimental studies show that hydrophobic bile acids can lead to liver injury through various mechanisms, such as death receptor signalling, mitochondrial dysfunction and inflammation. Although animal studies play a central role in investigating bile acid safety, there are considerable differences in bile acid composition, metabolism and hepatobiliary disposition across species. This does not allow appropriate safety inference, especially for predicting hepatotoxicity in humans. Exploring evidences stemming from inborn errors, genetic models of disease and toxicology studies further improves an understanding of bile acid hepatotoxicity. CONCLUSION Species differences should be considered in the development of bile acid related therapeutics. Although the mechanism of bile acid hepatotoxicity is still not fully understood, continued mechanistic studies will deepen our understanding.

Abstract
BACKGROUND Submental fat accumulation is a common cosmetic concern. Cryolipolysis utilizes noninvasive cooling to lyse adipocytes. A cryolipolysis device was recently approved for treatment of submental fat. OBJECTIVE This manuscript provides a review of the preclinical work and clinical trials related to cryolipolysis for the treatment of submental fat. Settings, efficacy, and side effects are also discussed. MATERIALS AND METHODS A literature search was performed through Pubmed, EMBASE, Web of Science, and CINAHL, using the search terms "cryolipolysis," "submental," and "paradoxical adipose hyperplasia". Additional sources from the original source bibliographies were used to further supplement this review. RESULTS There are 4 clinical trials and one case series (total 101 patients) that evaluated the use of cryolipolysis for treatment of submental fat. In these studies, there was a statistically significant reduction in submental fat and patients expressed high satisfaction with the treatment. Adverse effects were mild and transient. CONCLUSIONS Cryolipolysis is a noninvasive cooling technique that is safe and effective for treatment of submental fat. To date, there are no reports of marginal mandibular nerve injury or paradoxical adipose hyperplasia following treatment with this device.

Abstract
BACKGROUND A validated scale is needed for objective and reproducible comparisons of chin appearance before and after chin augmentation in practice and clinical studies. OBJECTIVE To describe the development and validation of the 5-point photonumeric Allergan Chin Retrusion Scale. METHODS The Allergan Chin Retrusion Scale was developed to include an assessment guide, verbal descriptors, morphed images, and real subject images for each scale grade. The clinical significance of a 1-point score difference was evaluated in a review of multiple image pairs representing varying differences in severity. Interrater and intrarater reliability was evaluated in a live-subject validation study (N = 298) completed during 2 sessions occurring 3 weeks apart. RESULTS A difference of ≥1 point on the scale was shown to reflect a clinically meaningful difference (mean [95% confidence interval] absolute score difference, 1.07 [0.94–1.20] for clinically different image pairs and 0.51 [0.39–0.63] for not clinically different pairs). Intrarater agreement between the 2 live-subject validation sessions was substantial (mean weighted kappa = 0.79). Interrater agreement was substantial during the second rating session (0.68, primary end point). CONCLUSION The Allergan Chin Retrusion Scale is a validated and reliable scale for physician rating of severity of chin retrusion.
