Lipedema is a pathology of the adipose tissue, in evident female prevalence, diagnosed clinically and still of not well-defined etiopathogenesis. Indeed, an estrogen-related component is present, and an inflammatory state and a condition of edema are present in most cases; even pain seems to be a recurring feature, and insulin resistance is also often associated with lipedema. The therapeutic approach is finally becoming holistic. Therefore, with surgery, physiotherapy, and elastic compression therapy, the nutritional aspect of food supplementation is gaining much value. The objective of the present work is to consider the nutritional supplements that could be useful to manage this condition, underlining that, at the moment, the specific literature is practically non-existent. The most promising supplements seem to be omega 3 fish oil, polyphenols, and vitamin C, but the need for studies in this sector is urgent.

Lipoedema is a chronic disease in adipose tissue that almost exclusively affects women during periods of hormonal alterations. Its main symptoms include an abnormal accumulation of subcutaneous fat in the buttock, hips, and legs, which is associated with pain, swelling, and easy bruising. Herein, a grading in three stages is used to determine disease progression. Problematically, lipoedema manifestations are often confused with lifestyle-induced obesity, which is why the various health problems among affected women often remain unrecognized. Overall, research on lipoedema is scarce. As such, this study examined the health, health-related quality of life (HRQOL), and sense of coherence (SOC) among women with lipoedema.

Lipedema is a common disorder characterized by excessive deposition of subcutaneous adipose tissue (SAT) in the legs, hips, and buttocks, mainly occurring in adult women. Although it appears to be heritable, no specific genes have yet been identified. To identify potential genetic risk factors for lipedema, we used bioelectrical impedance analysis and anthropometric data from the UK Biobank to identify women with and without a lipedema phenotype. Specifically, we identified women with both a high percentage of fat in the lower limbs and a relatively small waist, adjusting for hip circumference. We performed a genome-wide association study (GWAS) for this phenotype, and performed multiple sensitivity GWAS. In an independent case/control study of lipedema based on strict clinical criteria, we attempted to replicate our top hits. We identified 18 significant loci (p < 5 × 10−9), several of which have previously been identified in GWAS of waist-to-hip ratio with larger effects in women. Two loci (VEGFA and GRB14-COBLL1) were significantly associated with lipedema in the independent replication study. Follow-up analyses suggest an enrichment of genes expressed in blood vessels and adipose tissue, among other tissues. Our findings provide a starting point towards better understanding the genetic and physiological basis of lipedema.

BackgroundThere are both conservative and surgical treatment options for Lipohyperplasia dolorosa (LiDo). A procedure that has been established since 1997 is the surgical treatment through Lymphological Liposculpture according to Cornely™.AimAfter extensive suctioning of the extremities, an extensive subcutaneous wound cavity with a trabecular connective tissue scaffold remains. Nevertheless, surgery-related complications are rare. Postoperative management and administration of antibiotics and antithrombotics are reviewed. The therapies for complications are presented in detail.Materials and methodsRetrospectively, the frequencies of adverse events in 1400 LiDo surgeries in 2020 were evaluated. The mean age of the patients was 47.81 years (range 16–78 years). Symmetrically, 504 outer legs (outer half of the limb [BO]), 504 inner legs (inner half of the limb [BI]), and 392 arms [A] were surgically treated.ResultsRelevant adverse events rarely occurred: infections (1.79%), seromas (0.79%), erysipelas (0.28%), necrosis (0.14%) and deep vein thrombosis (0.07).DiscussionWe were able to reduce the rate of postoperative complications to 3.07% in the Lymphological Liposculpture™ regime for the surgical treatment of LiDo. In their meta-analysis on liposuction, Kanapathy et al. reported an overall incidence of major surgical complications of 3.35%. The overall incidence of minor surgical complications was 11.62%, with seroma (5.51%) being the most common minor complication [26]. Kruppa et al. report that the liposuction procedure including fat removal for esthetic reasons has a complication rate of 9.5%. Wound infections with 4.5% and the formation of erysipelas with 4% are clearly in the foreground [20].

In this study an analysis of identified ICG lymphography features of the superficial lymphatics of the lower extremity was undertaken [Table 2.2]. The absence or presence and extent of the superficial lymphatics in the limb with LLLE was assessed to identify if any of these features or combination of features were significantly associated with particular diagnostic groups of primary or secondary cancer related or secondary non-cancer related LLLE. ICG lymphography studies undertaken by the researcher (submitted for publication) had identified two compensatory lymph drainage regions, the contralateral inguinal and axillo-inguinal nodal regions, associated with secondary cancer related LLLE which were not seen or very rarely seen in clinically diagnosed primary LLLE and less so in secondary non-cancer related LLLE. Conversely, retrograde flow in lymph vessels demonstrated during the ICG lymphography procedure was not seen in secondary cancer related LLLE. These observations provided a background rationale to exploring the diagnostic capacity of ICG lymphography in LLLE. One purpose of this study was to explore the feasibility of using ICG lymphography features as a diagnostic tool. It was hoped that identified ICG lymphographic features would allow the individual presenting with persistent leg swelling of unknown causation to be able to be advised that their condition is most likely a secondary non cancer related LLLE rather than an adult onset primary LE and therefore be possibly less likely to progress or deteriorate. This may potentially provide better prognostic information and improve individualised therapeutic plans of management and support compliance (Pigott, 2021). The aim of Part A of this study was to identify the prevalence and characteristics of ICG lymphography features of the lymph vessels, position and extent of DBF and drainage patterns. In addition, Part B of this study was to explore whether using the ALERT standardised ICG lymphography technique and a structured analysis of ICG lymphography features could be translated into a simple score to distinguish the ICG pattern of adult onset primary LLLE from secondary non-cancer related LLLE.

The most relevant hallmarks of cellulite include a massive protrusion of superficial adipose tissue into the dermis, reduced expression of the extracellular glycoprotein fibulin-3, and an unusually high presence of MUSE cells in gluteofemoral white adipose tissue (gfWAT) that displays cellulite. Also typical for this condition is the hypertrophic nature of the underlying adipose tissue, the interaction of adipocytes with sweat glands, and dysfunctional lymph and blood circulation as well as a low-grade inflammation in the areas of gfWAT affected by cellulite. Here, we propose a new pathophysiology of cellulite, which connects this skin condition with selective accumulation of endogenous lipopolysaccharides (LPS) in gfWAT. The accumulation of LPS within a specific WAT depot has so far not been considered as a possible pathophysiological mechanism triggering localized WAT modifications, but may very well be involved in conditions such as cellulite and, secondary to that, lipedema.

Lipoedema is a chronic adipose tissue disorder mainly affecting women, causing excess subcutaneous fat deposition on the lower limbs with pain and tenderness. There is often a family history of lipoedema, suggesting a genetic origin, but the contribution of genetics is currently unclear. A tightly phenotyped cohort of 200 lipoedema patients was recruited from two UK specialist clinics. Objective clinical characteristics and measures of quality of life data were obtained. In an attempt to understand the genetic architecture of the disease better, genome-wide single nucleotide polymorphism (SNP) genotype data were obtained, and a genome wide association study (GWAS) was performed on 130 of the recruits. The analysis revealed genetic loci suggestively associated with the lipoedema phenotype, with further support provided by an independent cohort taken from the 100,000 Genomes Project. The top SNP rs1409440 (ORmeta ≈ 2.01, Pmeta ≈ 4 x 10–6) is located upstream of LHFPL6, which is thought to be involved with lipoma formation. Exactly how this relates to lipoedema is not yet understood. This first GWAS of a UK lipoedema cohort has identified genetic regions of suggestive association with the disease. Further replication of these findings in different populations is warranted.

Lipedema is a disease with abnormally increased adipose tissue deposition and distribution. Pain sensations have been described in the clinical evaluation of lipedema, but its etiology remains poorly understood. We hypothesized that pain sensitivity measurements and ex vivo quantitation of neuronal cell body distribution in the skin would be lipedema stage-dependent, and could, thus, serve to objectively characterize neuropathic pain in lipedema. The pain was assessed by questionnaire and peripheral cutaneous mechanical sensitization (von-Frey) in lipedema (n = 27) and control (n = 23) consenting female volunteers. Dermal biopsies from (n = 11) Stages 1–3 lipedema and control (n = 10) participants were characterized for neuronal cell body and nociceptive neuropeptide calcitonin gene-related peptide (CGRP) and nerve growth factor (NGF) distribution. Stage 2 or 3 lipedema participants responded positively to von Frey sensitization in the calf and thigh, and Stage 3 participants also responded in the arm. Lipedema abdominal skin displayed reduced Tuj-1+ neuronal cell body density, compared to healthy controls, while CGRP and NGF was significantly elevated in Stage 3 lipedema tissues. Together, dermal neuronal cell body loss is consistent with hyper-sensitization in patients with lipedema. Further study of neuropathic pain in lipedema may elucidate underlying disease mechanisms and inform lipedema clinical management and treatment impact.

Das Lipödem ist eine sehr komplexe, unvermutet häufig anzutreffende Erkrankung des Fettsystems der Extremitäten. Es handelt sich hier um ein lymphologisches Krankheitsbild, wobei besonders das Baufett betroffen ist. Nur in wenigen Fällen ist es auch mit metabolischen Symptomen assoziiert. Das Lipödem ist eine Sonderform der Adipositas, die weder in der Medizin noch in der Bevölkerung als bewegungs- und diätresistent wahrgenommen wird. Die betroffenen Patienten sind in ihrem seelischen Gleichgewicht äußerst betroffen. Aufgrund unserer anatomischen Untersuchungen kann man durchaus von einer ernsthaften, progressiven Erkrankung des subkutanen Fettgewebes und der benachbarten, assoziierten Strukturen sprechen. Es ist nicht nur die Klinik, sondern auch die duplexsonographische Evaluierung und impedanzanalytische Exploration sind zur Diagnosefindung und zur postoperativen Verlaufskontrolle notwendig. Auch bestätigt ein besonderes Verhalten der Stammzellen den Pathomechanismus. Durch Ausdünnung der Dermis und Verlust der elastischen Fasern sind dermatologische Problemstellungen wie Trockenheit, Infektneigung, Vulnerabilität und Neigung zu Ekchymosen erklärbar. Hier dürfte v. a. die Funktion des dermalen Fettes beeinträchtigt sein. Aus unseren Beobachtungen geht hervor, dass insbesondere die frühzeitige operative Therapie mittels Liposuktion einen nachhaltigen Wert für Patienten im Frühstadium hat und den Patienten eine deutliche Verbesserung der Lebensqualität bringt.

A 2022 UK guideline recommends that the liposuction procedure for treatment of lipedema should only be used in the context of research because of inadequate efficacy and safety data. A 2021 US guideline recognizes that liposuction is currently the only available technique for removing abnormal lipedema tissue. The guideline has a series of consensus statements on patient selection, indications for liposuction, prevention of procedure-related adverse events, and pre- and post-surgical management. There were no recent studies on the clinical effectiveness of liposuction compared with no treatment or to alternative treatments for the treatment of lipedema.

Background: Lipedema is a distinct adipose disorder from obesity necessitating awareness as well as different management approaches to address pain and optimize quality of life (QoL). The purpose of this proof-of-principle study is to evaluate the therapeutic potential of physical therapy interventions in women with lipedema. Methods and Results: Participants with Stage 1-2 lipedema and early Stage 0-1 lymphedema (n = 5, age = 38.4 ± 13.4 years, body mass index = 27.2 ± 4.3 kg/m2) underwent nine visits of physical therapy in 6 weeks for management of symptoms impacting functional mobility and QoL. Pre- and post-therapy, participants were scanned with 3 Tesla sodium and water magnetic resonance imaging (MRI), underwent biophysical measurements, and completed questionnaires measuring function and QoL (patient-specific functional scale, PSFS, and RAND-36). Pain was measured at each visit using the 0-10 visual analog scale (VAS). Treatment effect was calculated for all study variables. The primary symptomatology measures of pain and function revealed clinically significant post-treatment improvements and large treatment effects (Cohen's d for pain VAS = -2.5 and PSFS = 4.4). The primary sodium MRI measures, leg skin sodium, and subcutaneous adipose tissue (SAT) sodium, reduced following treatment and revealed large treatment effects (Cohen's d for skin sodium = -1.2 and SAT sodium = -0.9). Conclusions: This proof-of-principle study provides support that persons with lipedema can benefit from physical therapy to manage characteristic symptoms of leg pain and improve QoL. Objective MRI measurement of reduced tissue sodium in the skin and SAT regions indicates reduced inflammation in the treated limbs. Further research is warranted to optimize the conservative therapy approach in lipedema, a condition for which curative and disease-modifying treatments are unavailable.

Background The three-dimensional [3D] wound dressings Biobrane® and Epicite are used in the wound management. Fibroblasts are important for successful deep wound healing. The direct effect of Biobrane® and Epicite on human fibroblasts, particularly of juvenile individuals, remains unclear. Therefore, this study compared the survival and growth characteristics of juvenile and adult dermal fibroblasts on Biobrane® and Epicite using different culture models. Method Murine (L929), primary juvenile and adult human fibroblasts were seeded on both materials using two dimensional (2D, slide culture) or 3D culture at the medium-air interface and dynamical rotatory culture. Cell adherence, viability, morphology and actin cytoskeleton architecture were monitored. Scanning electron microscopy (SEM) analyses could be only performed from Biobrane®. Permeability and DNA amount of both materials were tested. Results The majority of all tested fibroblasts species survived on both dressings with no significant differences between 1 and 14 days. Juvenile and adult fibroblasts exerted typical fibroblast morphology with spindle-shaped cell bodies on the materials. SEM visualized morphological differences between murine and human fibroblasts on Biobrane®. Juvenile and adult fibroblasts colonized Biobrane® in rotatory culture after 7 days the most. The Biobrane® rotatory culture of L929 and juvenile fibroblasts showed after 7 days the significantly highest DNA amount. No major gender differences could be observed. Biobrane® had a higher permeability than Epicite. Conclusion Both wound dressing can be colonized by fibroblasts suggesting their high cytocompatibility. Fibroblast survival and morphology on Biobrane® and Epicite depended on the culture system and the fibroblast source.

There are many different causes of leg and foot swelling, some are benign and transient, others can be debilitating and progressive. Correct diagnosis and early treatment is crucial as conservative measures are most effective before the condition is allowed to progress. Current waiting times in the UK National Health Service (NHS) after the Covid-19 pandemic are leading to delays in care for people with chronic leg swelling. Delayed or inadequate treatment for these patients can lead to irreversible tissue damage, an episode of cellulitis, and progression to leg ulceration. There is in addition a significant impact on quality of life associated with living with the pain, anxiety, and reduced mobility. The causes of acute and chronic leg and foot swelling are outlined. Diagnosis and treatment of the common causes of leg and foot swelling in the Western adult population are discussed. The mainstay of treatment for most of these conditions relies on physical therapy and graduated elastic compression garments or elastic Velcro wraps as many do not have a cure.

Lymphedema and lipedema are complex diseases. While the external presentation of swollen legs in lower-extremity lymphedema and lipedema appear similar, current mechanistic understandings of these diseases indicate unique aspects of their underlying pathophysiology. They share certain clinical features, such as fluid (edema), fat (adipose expansion), and fibrosis (extracellular matrix remodeling). Yet, these diverge on their time course and known molecular regulators of pathophysiology and genetics. This divergence likely indicates a unique route leading to interstitial fluid accumulation and subsequent inflammation in lymphedema versus lipedema. Identifying disease mechanisms that are causal and which are merely indicative of the condition is far more explored in lymphedema than in lipedema. In primary lymphedema, discoveries of genetic mutations link molecular markers to mechanisms of lymphatic disease. Much work remains in this area towards better risk assessment of secondary lymphedema and the hopeful discovery of validated genetic diagnostics for lipedema. The purpose of this review is to expose the distinct and shared (i) clinical criteria and symptomatology, (ii) molecular regulators and pathophysiology, and (iii) genetic markers of lymphedema and lipedema to help inform future research in this field.

Abstract Objectives Lipoedema is a chronic fat disorder involving an excessive abnormal deposition of subcutaneous fat in the thighs, legs, hips and buttocks mainly (Wounds UK, 2017). The importance of healthy eating in lipoedema management has been recognised (Wounds UK, 2017), yet dietary guidelines specific for lipoedema are lacking (Bertsch et al., 2020). The study aimed to investigate the self-reported dietary and lifestyle impact on lipoedema management among a representative lipoedema population in the UK. Methods The study used an online questionnaire that consisted of multiple-choice and open-response questions to collect data on symptoms and diagnostic status of lipoedema and self-reported dietary and lifestyle impact on lipoedema management among participants. The questionnaire was constructed using the Survey Monkey software. The active online survey link was sent to Lipoedema UK's members and contacts via e-mail and also made accessible via the study flyer advertised on Lipoedema UK's website and newsletters. Ethical approval was obtained from the De Montfort University Faculty Research Ethics Committee of Health and Life Sciences prior to the study. Participants had given their consents before starting the survey. Data collection was anonymous. Data were analysed using SPSS v26.0. Results The results showed that 165 out of 257 participants (66.3%) had tried diet as a mean to improve their lipoedema symptoms in the past. Anti-inflammatory diet was reported to be one of the three most effective diets that improved their symptoms (either single or multiple). The other two diets were ketogenic diet and rare adipose disorder diet. Noticeably, 95% of the 257 participants were classified as either overweight or obese based on their Body Mass Index (BMI) measure. And 20% of the participants who tried weight loss diets had found improvements in their lipoedema conditions. Conclusions The study results will help inform the development of future research on finding a dietary solution to effective lipoedema management for the UK lipoedema population. Funding Sources De Montfort University funded the recruitment of a Research Assistant to support part of the data analysis work.
