Surgery may not always be the best option, case report finds

OBJECTIVE: Lipedema is a chronic and progressive disease associated with lymphatic impairment at later stages. The aim of our study was to describe the functional status and anatomy of lower limb superficial lymphatic system using indocyanine green (ICG) lymphography in patients with lipedema. METHODS: Following ICG injection at the dorsum of the foot, distance (cm) covered by the dye at 10 (T10') and 25 min (T25') was measured and normalized for limb length. If the dye did not reach the groin within 25 min, patients were classified as "drainage-needing" group (DNG). Values of fat and lean distribution assessed by dual-energy X-ray absorptiometry were extracted, and correlation analysis was performed. Furthermore, anatomical patterns of superficial lymphatics were assessed. RESULTS: Overall, 45 women were included, 25 (56%) of whom were classified as DNG. Symptoms duration was significantly associated with DNG status at multivariate analysis (odds ratio 1.07; 95% CI 1.01-1.14; p = 0.047). Moreover, Spearman's analysis showed a negative correlation between symptoms duration and T25' dye migration (r = -0.469; p = 0.037). Overall, no major anatomical lymphatic changes were found. CONCLUSIONS: Present study suggests that lymphatic functioning in patients with lipedema correlates with symptoms duration. Further research on larger cohorts should verify our findings and clarify their potential therapeutic implications. Overall, ICG lymphography may be promising technique to assess both lymphatic anatomy and functioning in patients with lipedema.

Background: Expressed by endothelial cells, CDH5 is a cadherin involved in vascular morphogenesis and in the maintenance of vascular integrity and lymphatic function. The main purpose of our study was to identify distinct variants of the CDH5 gene that could be associated with lymphatic malformations and predisposition for lymphedema. Methods and Results: We performed Next Generation Sequencing of the CDH5 gene in 235 Italian patients diagnosed with lymphedema but who tested negative for variants in known lymphedema genes. We detected six different variants in CDH5 five missense and one nonsense. We also tested available family members of the probands. For family members who carried the same variant as the proband, we performed lymphoscintigraphy to detect any lymphatic system abnormalities. Variants were modeled in silico. The results showed that CDH5 variants may contribute to the onset of lymphedema, although further in vitro studies are needed to confirm this hypothesis. Conclusions: Based on our findings, we propose CDH5 as a new gene that could be screened in patients with lymphedema to gather additional evidence.

Background Lipedema is an underdiagnosed condition in women, characterized by a symmetrical increase in subcutaneous adipose tissue (SAT) in the lower extremities, sparing the trunk. The lipedema SAT has been found to be resistant to diet, exercise and bariatric surgery, in regard to both weight loss (WL) and symptom relief. Current experience indicates that a low carbohydrate and high fat (LCHF-diet) might have a beneficial effect on weight and symptom management in lipedema. Objective To assess the impact of an eucaloric low carbohydrate, high fat (LCHF)-diet on pain and quality of life (QoL) in patients with lipedema. Methods Women diagnosed with lipedema, including all types and stages affecting the legs, (age 18-75 years, BMI 30-45 kg/m2) underwent 7 weeks (wk) of LCHF-diet and, thereafter 6 wk of a diet following the Nordic nutrition recommendations. Pain (visual analog scale) and QoL (questionnaire for lymphedema of the limbs), weight and body composition were measured at baseline, wk 7 and 13. Results Nine women (BMI: 36.7±4.5kg/m2 and age: 46.9±7 years) were recruited. The LCHF diet induced a significant WL -4.6±0.7 kg (-4.5±2.4%), P<0.001 for both, and reduction in pain (-2.3±0.4 cm, P=0.020). No correlation was found between WL and changes in pain at wk 7 (r = 0.283, P = 0.460). WL was maintained between wk 7 and 13 (0.3±0.7 kg, P=0.430), but pain returned to baseline levels at wk 13 (4.2±0.7 cm ,P=0.690). A significant increase in general QoL was found between baseline and wk 7 (1.0 (95% CI (2.0, 0.001), P=0.050) and 13 (1.0 95% CI (2.0, 0.001) P=0.050), respectively. Conclusion A LCHF-diet is associated with reduction in perceived pain and improvement in QoL, in patients with lipedema. Larger randomized clinical trials are needed to confirm these findings.

Lipedema is a pathology of adipose tissue, still of unclear etiology and challenging to diagnose. For these reasons, a therapeutic approach is also complex and sometimes controversial. The inflammation state present in lipedema can be limited by controlling the glycemic peaks. Specifically, the ketogenic diet (KD) seems to have the right conditions to be effective. Herein, we reported a subject diagnosed with lipedema who, with only KD nutritional intervention, achieved a significant weight loss (&minus;41 Kg), with a net decrease in body circumferences, and also reporting an improvement in pain, and therefore in the overall quality of life. She refused other types of intervention and kept KD for two years. This case could represent the first step to organize a KD nutritional protocol specifically applied to lipedema.

Dercum's disease (DD), also described as adiposis dolorosa, is a poorly understood and rare adipose tissue disorder involving obesity and painful adipose tissue masses. Patients may have associated bruising and constitutional symptoms such as fatigue, difficulty concentrating, and sleep disturbance. DD was initially described in 1888 by Francis Xavier Dercum, and was classified into four subtypes, including generalized diffuse, generalized nodular, localized nodular, and juxta-articular subtypes. While this disease has been described for more than 130 years, its etiology and treatment remain elusive. We describe a case of a patient with DD who presented to Ochsner Medical Center, New Orleans, LA, for evaluation of treatment options. We review current knowledge on this rare disease and data on modern treatment methods.

Lipedema, a poorly understood chronic disease of adipose hyper-deposition, is often mistaken for obesity and causes significant impairment to mobility and quality-of-life. To identify molecular mechanisms underpinning lipedema, we employed comprehensive omics-based comparative analyses of whole tissue, adipocyte precursors (adipose-derived stem cells (ADSCs)), and adipocytes from patients with or without lipedema.

Adipose tissue, once thought to be an inert receptacle for energy storage, is now recognized as a complex tissue with multiple resident cell populations which actively collaborate in response to diverse local and systemic metabolic, thermal, and inflammatory signals. A key participant in adipose tissue homeostasis that has only recently captured broad scientific attention is the lymphatic vasculature. The lymphatic system's role in lipid trafficking and mediating inflammation makes it a natural partner in the regulation of adipose tissue, and evidence supporting a bidirectional relationship between lymphatics and adipose tissue has accumulated in recent years. Obesity is now understood to impair lymphatic function, while altered lymphatic function results in aberrant adipose tissue deposition, though the molecular mechanisms governing these phenomena have yet to be fully elucidated. We will review our current understanding of the relationship between adipose tissue and the lymphatic system here, focusing on known mechanisms of lymphatic-adipose cross-talk.

Lipedema is a painful fat disorder that affects ~11% of the female population. It is characterized by bilateral, disproportionate accumulation of subcutaneous adipose tissue predominantly in the lower body. The onset of lipedema pathophysiology is thought to occur during periods of hormonal fluctuation, such as puberty, pregnancy, or menopause. Although the identification and characterization of lipedema have improved, the underlying disease etiology remains to be elucidated. Estrogen, a key regulator of adipocyte lipid and glucose metabolism, and female-associated body fat distribution are postulated to play a contributory role in the pathophysiology of lipedema. Dysregulation of adipose tissue accumulation via estrogen signaling likely occurs by two mechanisms: (1). altered adipocyte estrogen receptor distribution (ERα/ERß ratio) and subsequent metabolic signaling and/or (2). increased release of adipocyte-produced steroidogenic enzymes leading to increased paracrine estrogen release. These alterations could result in increased activation of peroxisome proliferator-activated receptor γ (PPARγ), free fatty acid entry into adipocytes, glucose uptake, and angiogenesis while decreasing lipolysis, mitochondriogenesis, and mitochondrial function. Together, these metabolic alterations would lead to increased adipogenesis and adipocyte lipid deposition, resulting in increased adipose depot mass. This review summarizes research characterizing estrogen-mediated adipose tissue metabolism and its possible relation to excessive adipose tissue accumulation associated with lipedema.

Dr. Allen and Dr. Hines pioneered and first described lipedema in the 1940s, a common subcutaneous adipose tissue disorder characterized as enlargement of both lower extremities. Lipedema is not edema; it is a genetically determined disturbance in adipose tissue mass and adipose tissue distribution.[1][2][3][4] In 1951 a second seminal paper provided more description of lipedema. Fat distribution involves lower extremities, upper arms, hips, buttocks, thighs sparing trunks, and feet.[2] Lower extremities are characterized by pain, easy bruisability, firm subcutaneous nodules of adipose tissue, and resistance of fat to traditional diet and exercise.[5][6]

Lipoedema UK welcomed our involvement with NICE and the opportunity to comment on noncosmetic liposuction (NCL) as a proposed interventional procedure for chronic lipoedema. In response, we have been proactive in capturing the views and experiences of individuals in the UK living with lipoedema and from those who have undergone non-cosmetic liposuction.

The article presents a case of a 17-year-old female who was presented to a clinic due to a 2-year history of unilateral swelling of her left lower extremity. She also reported a poorly healed ankle sprain on her affected extremity. Also cited are her differential diagnosis like lipidema and lymphatic and venous etiologies of edema, and her clinical diagnosis of lymphedema praecox.

<p>Bei 640 Patientinnen einer Fachklinik für operative Lymphologie erfolgte mittels Fragebogen der Deutschen Schmerzgesellschaft e. V. eine Befragung. Neben Fragen zum Schmerz und zur Schmerzcharakteristik wurden gleichzeitig noch demografische Daten miterhoben. Es ergab sich, dass nur bei etwas über 50 % eine echte Adipositas nachgewiesen werden konnte. Lipödem und Adipositas müssen als unabhängige Krankheitsbilder gewertet werden. Der Schmerz wurde überwiegend als drückend und ziehend empfunden. Attribute wie klopfend oder pochend, passend zu einer akuten Entzündung, erfuhren die Wertung „nicht zutreffend“. Die Beschwerdesymptomatik war unabhängig vom BMI, der bei der Lipohyperplasie dolorosa nur bedingt verwertbar ist. Insgesamt ist das Leitsymptom „Schmerz“ sehr facettenreich, das angeborene, nicht erworbene Lipödemfett der Extremitäten führt zu einer deutlichen Beeinträchtigung der Aktivitäten sowohl allgemein als auch im Freizeitbereich. Die durch den G-BA initiierte Studie muss daher kritisch gesehen werden. Da bislang keine objektivierbaren Befunde beim Lipödem erhoben werden können, ist eine subtile Befragung betroffener Patientinnen zur Diagnosestellung notwendig.</p>

(1) Background: Lipoedema is a disease characterized by excessive bilateral and symmetrical accumulation of subcutaneous tissue in the lower extremities. It is a poorly understood condition, and low awareness of its existence often leads to incorrect diagnosis Initially, lipoedema was considered to be completely independent of lifestyle Currently, however, more and more cases of the coexistence of lipoedema and obesity are described in the literature as additionally affecting the severity of the disease The aim of the review is to present lipoedema as a social problem. (2) Methods: Materials on lipoedema in the social context were selected from 2018-2021. The PRISMA-Scr checklist was used in the review. (3) Results: Research has shown that more than 3/4 of patients with lipoedema are also overweight or obese. Patients with lipoedema have many comorbidities, and their presence negatively affects the quality of life. The quality of life in patients with lipoedema is lower than in healthy patients. (4) Conclusions: The number of studies available on lipoedema is low. Obesity is common in patients with lipoedema. Mental disorders increase the level of experienced pain. Lipoedema significantly reduces quality of life. A healthy lifestyle in patients with lipoedema could be helpful for prevention of complications and disability.

Whole-body three-dimensional surface imaging (3DSI) offers the ability to monitor morphologic changes in multiple areas without the need to individually scan every anatomical region of interest. One area of application is the digital quantification of leg volume. Certain types of morphology do not permit complete circumferential scan of the leg surface. A workflow capable of precisely estimating the missing data is therefore required. We thus aimed to describe and apply a novel workflow to collect bilateral leg volume measurements from whole-body 3D surface scans regardless of leg morphology and to assess workflow precision. For each study participant, whole-body 3DSI was conducted twice successively in a single session with subject repositioning between scans. Paired samples of bilateral leg volume were calculated from the 3D surface data, with workflow variations for complete and limited leg surface visibility. Workflow precision was assessed by calculating the relative percent differences between repeated leg volumes. A total of 82 subjects were included in this study. The mean relative differences between paired left and right leg volumes were 0.73 ± 0.62% and 0.82 ± 0.65%. The workflow variations for completely and partially visible leg surfaces yielded similarly low values. The workflow examined in this study provides a precise method to digitally monitor leg volume regardless of leg morphology. It could aid in objectively comparing medical treatment options of the leg in a clinical setting. Whole-body scans acquired using the described 3DSI routine may allow simultaneous assessment of other changes in body morphology after further validation.

Objective: Lipedema is a relatively common yet debilitating and often misdiagnosed lipodystrophy that mainly affects females. Very little is known about the etiology and pathophysiology of the disease. However, due to its high preference for female patients, hormonal factors may contribute to the pathogenesis., Case: A 62-year-old male patient presented to the authors with painful swelling of the thighs. The patient had been treated elsewhere for lymphedema with subsequent disease progression. Lipedema stage IV was confirmed by clinical examination and ultrasound. The patient underwent three sessions of tumescence liposuction which was well tolerated. Later on, the patient reported great improvement in terms of complaints as well as disfigurement., Conclusion: The etiology and pathophysiology of lipedema remain unclear. However, the case at hand shows that lipedema may, albeit rare, also present in male patients. Moreover, we show that liposuction is efficient and safe in treating lipedema even in atypical cases.

Lymphedema is a chronic disease with a high incidence in our society. In this paper, we present a review with the latest advances in imaging techniques and surgical reconstructive treatment of lymphedema (lymphovenous anastomosis, vascularized lymph node transfer, and prophylactic lymphedema surgery). In addition, a protocol is established based on a multidisciplinary team (composed of physiatrists, plastic surgeons, radiologists and nuclear medicine radiologists) to optimize the treatment of these patients.
