Background and Aim: Lipedema is a common painful SAT disorder characterized by enlargement of fat primarily in the legs of women. Case reports of lipedema tissue samples demonstrate fluid and fibrosis in the interstitial matrix, increased macrophages, and adipocyte hypertrophy. The aims of this project are to investigate blood vasculature, immune cells, and structure of lipedema tissue in a cohort of women. Methods: Forty-nine participants, 19 controls and 30 with lipedema, were divided into groups based on body mass index (BMI): Non-Obese (BMI 20 to <30 kg/m2) and Obese (BMI 30 to <40 kg/m2). Histological sections from thigh skin and fat were stained with H&E. Adipocyte area and blood vessel size and number were quantified using ImageJ software. Markers for macrophages (CD68), mast cells (CD117), T cells (CD3), endothelial cells (CD31), blood (SMA), and lymphatic (D2-40 and Lyve-1) vessels were investigated by IHC and IF. Results: Non-Obese Lipedema adipocyte area was larger than Non-Obese Controls (p=0.005) and similar to Obese Lipedema and Obese Controls. Macrophage numbers were significantly increased in Non-Obese (p < 0.005) and Obese (p < 0.05) Lipedema skin and fat compared to Control groups. No differences in T lymphocytes or mast cells were observed when comparing Lipedema to Control in both groups. SMA staining revealed increased dermal vessels in Non-Obese Lipedema patients (p < 0.001) compared to Non-Obese Controls. Lyve-1 and D2-40 staining showed a significant increase in lymphatic vessel area but not in number or perimeter in Obese Lipedema participants (p < 0.05) compared to Controls (Obese and Non-Obese). Areas of angiogenesis were found in the fat in 30% of lipedema participants but not controls. Conclusion: Hypertrophic adipocytes, increased numbers of macrophages and blood vessels, and dilation of capillaries in thigh tissue of non-obese women with lipedema suggest inflammation, and angiogenesis occurs independent of obesity and demonstrates a role of altered vasculature in the manifestation of the disease.

Subcutaneous adipose tissue diseases involving adipose tissue and its fascia, also known as adipofascial disorders, represent variations in the spectrum of obesity. The adipofascia diseases discussed in this chapter can be localized or generalized and include a common disorder primarily affecting women, lipedema, and four rare diseases, familial multiple lipomatosis, angiolipomatosis, Dercum disease, and multiple symmetric lipomatosis. The fat in adipofascial disorders is difficult to lose by standard weight loss approaches, including lifestyle (diet, exercise), pharmacologic therapy, and even bariatric surgery, due in part to tissue fibrosis. In the management of obesity, healthcare providers should be aware of this difficulty and be able to provide appropriate counseling and care of these conditions. Endocrinologists and primary care providers alike will encounter these conditions and should consider their occurrence during workup for bariatric surgery or hypothyroidism (lipedema) and in those that manifest, or are referred for, dyslipidemia or diabetes (Dercum disease). People with angiolipomas should be worked up for Cowden’s disease where a mutation in the gene PTEN increases their risk for thyroid and breast cancer. This chapter provides details on the pathophysiology, prevalence, genetics and treatments for these adipofascial disorders along with recommendations for the care of people with these diseases.

Obesity is a clinical condition that affects millions of people around the world and is associated with inflammatory processes. The aim of the present study was to report the association between obesity, lipedema, and systemic fluid retention, characterizing subclinical systemic lymphedema with aggravating factors. A 50-year-old female patient weighing 150 kilograms (body mass index: 60.2 kg/m2) reported being obese since childhood, but more located on the hips. She had a family history of this body configuration. Electrical bioimpedance analysis revealed generalized edema, constituting systemic lymphedema. Subclinical systemic lymphedema is caused by obesity and lipedema is also associated with this condition.

An endothelial cell monolayer separates interstitia from blood and lymph, and determines the bidirectional transfer of solutes and macromolecules across these biological spaces. We review advances in transport modalities across these endothelial barriers. Glucose is a major fuel for the brain and peripheral tissues, and insulin acts on both central and peripheral tissues to promote whole-body metabolic signalling and anabolic activity. Blood-brain barrier endothelial cells display stringent tight junctions and lack pinocytic activity. Delivery of blood glucose and insulin to the brain occurs through their respective carrier (Glucose transporter 1) and receptor (insulin receptor), enacting bona fide transcytosis. At supraphysiological concentrations, insulin is also likely transferred by fluid phase cellular uptake and paracellular transport, especially in peripheral microvascular endothelia. The lymphatic microvasculature also transports insulin but in this case from tissues to lymph and therefrom to blood. This serves to end the hormone's action and to absorb highly concentrated subcutaneously injected insulin in diabetic individuals. The former function may involve receptor-mediated transcytosis into lymphatic endothelial cells, the latter fluid phase uptake and paracellular transport. Lymphatic capillaries also mediate carrierdependent transport of other nutrients and macromolecules. These findings challenge the notion that lymphatic capillaries only transport macromolecules through intercellular flaps.

The purpose of this work was to quantify 3.0 T (i) T(1) and T(2) relaxation times of in vivo human lymph nodes (LNs) and (ii) LN relaxometry differences between healthy LNs and LNs from patients with lymphatic insufficiency secondary to breast cancer treatment-related lymphedema (BCRL). MR relaxometry was performed over bilateral axillary regions at 3.0 T in healthy female controls (105 LNs from 20 participants) and patients with BCRL (108 LNs from 20 participants). Quantitative T(1) maps were calculated using a multi-flip-angle (20, 40, 60°) method with B(1) correction (dual-T(R) method, T(R1) /T(R2)  = 30/130 ms), and T(2) maps using a multi-echo (T(E)  = 9-189 ms; 12 ms intervals) method. T(1) and T(2) were quantified in the LN cortex and hilum. A Mann-Whitney U-test was applied to compare LN relaxometry values between patients and controls (significance, two sided, p < 0.05). Linear regression was applied to evaluate how LN relaxometry varied with age, BMI, and clinical indicators of disease. LN substructure relaxation times (mean ± standard deviation) in healthy controls were T(1) cortex, 1435 ± 391 ms; T(1) hilum, 714 ± 123 ms; T(2) cortex, 102 ± 12 ms, and T(2) hilum, 119 ± 21 ms. T(1) of the LN cortex was significantly reduced in the contralateral axilla of BCRL patients compared with the axilla on the surgical side (p < 0.001) and compared with bilateral control values (p < 0.01). The LN cortex T(1) asymmetry discriminated cases from controls (p = 0.004) in a multiple linear regression, accounting for age and BMI. Human 3.0 T T(1) and T(2) relaxation times in axillary LNs were quantified for the first time in vivo. Measured values are relevant for optimizing acquisition parameters in anatomical lymphatic imaging sequences, and can serve as a reference for novel functional and molecular LN imaging methods that require quantitative knowledge of LN relaxation times.

Lipoedema is a rare painful disorder of the adipose tissue. It essentially affects females and is often misdiagnosed as lymphoedema or obesity. It is globally misdiagnosed or underdiagnosed, and the literature is lacking appropriate guidance to assist clinicians towards this diagnosis. However, the need to recognise this disorder as a unique entity has important implications to establish proper treatment and, therefore, its tremendous effect on patients. Early diagnosis and treatment can turn these patients' lives upside down. The aim of this review is to focus on the clinical guidance, differential diagnosis, and management strategies. In addition, other aspects of lipoedema, including epidemiology and pathogenesis, are also being discussed here. Lipoedema is distinct from obesity and distinct from lymphoedema, although it might progress to involve the venous and lymphatic system (venolipedema or lympholipedema or both). Late diagnosis can leave the patient debilitated. Management of lipoedema includes weight loss, control of oedema, complex decongestive physiotherapy, liposuction, and laser-assisted lipolysis. However; there are increasing reports on tumescent liposuction as the preferred surgical option with long-lasting results. The role of more randomised controlled studies to further explore the management of this clinical entity remains promising.

OBJECTIVE: We assessed body composition, bone mineral density (BMD), glucose and lipids in Williams syndrome (WS), a rare microdeletion disorder. DESIGN: Individuals with WS had outpatient assessment at Massachusetts General Hospital. Controls were selected from the National Health and Nutrition Examination Survey (NHANES 2005-2006). PATIENTS: A total of 22 individuals with WS, each matched by age, sex and race to four NHANES controls. MEASUREMENTS: Blood sampling, oral glucose tolerance test, dual-energy X-ray absorptiometry scan. RESULTS: WS and control groups were 59% female and 29 ± 8 years old. Compared to controls, individuals with WS were shorter but had similar body weight, with more fat and less lean mass. Per cent body fat was higher in WS even after adjusting for BMI (+2.1% [95% CI 0.4, 3.9%]). Four WS patients had abnormal lower extremity fat accumulation resembling lipedema. HbA1c (+0.5% [0.2, 0.7]) and 2-hour glucose (+68 mg/dL [44, 93]) were higher in WS vs controls, differences which persisted after adjusting for BMI. Fasting glucose was comparable between groups. LDL (-18 mg/dL [-35, -2]) and triglycerides (-45 mg/dL [-87, -2]) were significantly lower in WS. Whole-body BMD was significantly lower (-0.15 g/cm(2) [-0.20, -0.11]) in WS, and this remained true controlling for height (-0.06 g/cm(2) [-0.11, -0.02]). Vitamin D was <30 ng/mL in 81% of those with WS. CONCLUSIONS: On average, adults with WS have increased fat, decreased lean mass, impaired glucose homeostasis and reduced BMD. Clinical efforts to build muscle and bone mass, and to ensure vitamin D sufficiency, are warranted. Genotype-phenotype research efforts are also warranted.

Lipedema is a chronic, progressive adipose tissue disorder that may impact the quality of life of women who suffer from it. The main aim of this study was to asses the role of perceived symptom severity, physical and psychological functioning with the disease in predicting quality of life in patients with lipedema. We conducted an online study with 329 participants who responded to five questionnaires measuring quality of life (World Health Organization Quality of Life BREF), lipedema symptom severity, mobility (Lower Extremity Functional Scale), depression (Patients Health Questionnaire-9), and appearance-related distress (Derriford Appearance Scale 24). Multiple hierarchical regression analyses showed that appearance-related distress and depression explained significantly more variance in quality of life when added to the symptom severity and mobility. Lower quality of life was predicted by higher symptom severity, lower mobility, higher appearance-related distress and higher depression severity. Appearance-related distress and depression constitute important aspects of psychological functioning in women with lipedema. Considering their relationship with quality of life, their assessment should be included in lipedema treatment with appropriate interventions aimed at decreasing appearance-related distress, as well as preventing and addressing depression.

Um das Lipödem ranken sich zahlreiche Mythen! In dieser kleinen Übersichtsreihe über die Mythen des Lipödems werfen wir einen kritischen Blick auf populäre Statements zum Lipödem; Statements, die vor Jahrzehnten schon Eingang in wissenschaftliche Publikationen gefunden haben und seither unkritisch und stetig wiederholt werden; Statements, die dadurch inzwischen zum selbstverständlichen Wissensallgemeingut von Lipödempatientinnen und vor allem auch von Lipödem-Selbsthilfegruppen geworden sind. Im ersten Teil unserer Darstellung haben wir uns kritisch mit zwei populären Mythen über das Lipödem auseinandergesetzt. Hierbei haben wir festgestellt, dass sowohl für das Statement „Das Lipödem ist eine progrediente Erkrankung” als auch für das Statement „Ein Lipödem macht psychisch krank” keine wissenschaftliche Evidenz vorliegt. In einem zweiten Beitrag über die Mythen des Lipödems fokussierten wir uns auf den Ödemaspekt, auf das „Ödem im Lipödem” und die hieraus erfolgende therapeutische Konsequenz: die Manuelle Lymphdrainage. Wir konnten darlegen, dass für das populäre Statement „Das Lipödem ist in erster Linie ein „Ödem-Problem”, daher ist die Manuelle Lymphdrainage essenzielle und regelmäßig durchzuführende Standardtherapie” ebenfalls keine wissenschaftliche Evidenz existiert. Der regelmäßigen und dauerhaften Verordnung von Manuellen Lymphdrainagen mit dem Ziel der „Ödembeseitigung” fehlt daher jede Grundlage. In diesem dritten Teil der Auseinandersetzung über bekannte und oft zitierte” Lipödem-Statements” beschäftigen wir uns mit zwei weiteren Mythen: 4. „Das Lipödem macht dick” und 5. „Gewicht abnehmen hat keinen Effekt auf das Lipödem”. Für beide Statements gibt es weder ein sinnvolles physiologisches bzw. pathophysiologisches Konstrukt noch eine sich in der Literatur findende wissenschaftliche Evidenz. Darüber hinaus widersprechen beide Statements in hohem Maße unserer seit Jahren bestehenden täglichen klinischen Erfahrung mit Lipödempatientinnen. Tatsächlich scheint das Gegenteil richtig: Gewichtszunahme wirkt als entscheidender Trigger, um – bei entsprechend genetischer Disposition für ein Lipödem – dieses überhaupt erst zu entwickeln. Lipödem und Adipositas sind zwei unterschiedliche Erkrankungen, die jedoch in den meisten Fällen gemeinsam auftreten. Fast täglich sehen wir Lipödempatientinnen, die sich aufgrund ihrer morbiden Adipositas einer bariatrischen Operation unterzogen und dadurch effektiv – auch im Bereich der Extremitäten – Gewicht verloren haben. Patientinnen mit Lipödem erfahren durch diese meist nachhaltige Gewichtsabnahme regelhaft eine deutliche Besserung ihrer lipödemtypischen Schmerzen. Häufig sind die Patienten dann beschwerdefrei, sodass wir dann von einem Lipödem in Remission sprechen können. In einem vierten Beitrag werden wir uns mit dem Stellenwert der Liposuktion beim Lipödem beschäftigen, um dann in unserer letzten Darstellung ein therapeutisches Konzept vorzustellen, das nicht nur wissenschaftlich fundiert ist, sondern auch zu einer nachhaltigeren und umfassenderen Beschwerdebesserung unserer Lipödempatientinnen beitragen soll.

INTRODUCTION: Lipoedema is a chronic disorder in which excessive fat distribution occurs predominantly from the waist down, resulting in a disproportion between the lower extremities and upper torso. Lipoedema is often not recognized, while patients experience pain and easy bruising. As a long-term condition, lipoedema has a massive effect on patients' lives and mental health. The aim of this study is to explore patient characteristics, quality of life, physical complaints and comorbidities in patients with lipoedema. METHODS: A survey was conducted by email amongst lipoedema patients, consisting of informed consent and multiple questionnaires. The questionnaires included general patient characteristics, physical complaints, comorbidities, RAND-36 and EQ-5D-3L. Participants who responded to a message on the Dutch Lipoedema Association website were recruited. RESULTS: All lipoedema patients experience physical complaints, with pain (88.3 %) and easy bruising (85.9 %) as primary complaints. The diagnosis was mostly made by a dermatologist after visiting a mean of 2.8 doctors. Furthermore, mean time from onset until diagnosis was 18 years. Quality of life (59.3) was significantly lower than the Dutch female average (74.9; p < 0.001). Additionally, patients with comorbidities had significant lower quality of life (RAND 54.7, p < 0.001). CONCLUSIONS: Lipoedema patients often have severe complaints and experience lower quality of life regarding physical, emotional and social functioning. Additionally, comorbidities have a large impact on quality of life.

Adipose tissue is a specialized connective tissue which, depending on type, plays different and significant roles in the human body: protects against environmental factors, stores lipids and triacylglycerol, synthesizes fatty acids and is involved in the process of thermogenesis. It is also a major secretory organ and highly active metabolic tissue. It secretes, for example, cholesterol, retinol, steroid hormones, prostaglandins and proteins known as "adipokines". Some of these molecules may be associated with pathologies such as obesity and insulin resistance. In humans, there are two main sites of adipose tissue accumulation: visceral and subcutaneous. Obesity is a worldwide health problem. This book also discusses a series of up-to-date topics about this pathology.

In diesem zweiten Beitrag über die Mythen des Lipödems fokussieren wir uns auf den Ödemaspekt, auf das „Ödem im Lipödem” und die hieraus erfolgte therapeutische Konsequenz – die Manuelle Lymphdrainage. Daher: Mythos 3: Das Lipödem ist in erster Linie ein „Ödem-Problem”; daher ist die Manuelle Lymphdrainage essenzielle und regelmäßig durchzuführende Standardtherapie! Auch dieses Statement widerspricht in hohem Maße unserer seit Jahren bestehenden täglichen klinischen Erfahrung mit diesem speziellen Patientengut. Gleichzeitig haben wir im Rahmen unserer umfangreichen Literaturrecherche festgestellt, dass es keine Evidenz für diese Sichtweise gibt. Tatsächlich gibt es keinerlei Hinweis darauf, dass beim Lipödem ein relevantes Ödem – Ödem im Sinne von Flüssigkeit – vorliegt. Ebenso fehlt jegliche wissenschaftliche Evidenz dafür, dass dieses kaum (bzw. meist nicht) vorhandene Ödem für die Beschwerden der Lipödempatientinnen verantwortlich ist. Der regelmäßigen und dauerhaften Verordnung von Manuellen Lymphdrainagen mit dem Ziel der „Ödembeseitigung” fehlt daher jede Grundlage. Das Lipödem ist weit mehr als nur dickere, schmerzhafte Beine! Darum müssen wir manche der alten therapeutischen Pfade verlassen, Pfade, für die es keine wissenschaftliche Evidenz gibt, Pfade, die darüber hinaus auch unserer klinischen Erfahrung widersprechen. Eine umfassende Therapie des Lipödems sollte daher auch all jene Aspekte berücksichtigen, die nicht so offensichtlich sind wie das Augenscheinliche und das vordergründig Geäußerte. Lipödem-Therapie muss neben der Behandlung der somatischen Beschwerden auch auf die bereits in unserem ersten Beitrag beschriebenen psychosozialen und gesellschaftlichen Aspekte dieses komplexen Krankheitsbildes fokussieren. Die Vorstellung eines umfassenden Therapiekonzeptes für Lipödempatientinnen wird Inhalt im letzten Teil unserer kleinen Lipödemreihe sein. Neue Wege entstehen, in dem wir sie gehen – dies gilt auch für die Therapie des Lipödems!</p>

Lipedema is a little-known alteration or disorder in the distribution of body fat, which affects almost exclusively women and primarily involves the lower extremities.   Epidemiological data are currently scarce and not helpful to determine the exact incidence of lipedema in the general population; its etiology and physiopathology are not clear enough; its diagnosis is basically clinical, since there are no specific diagnostic tests or enough scientific evidence to support it. However, its clinical manifestations imply deterioration in patients’ quality of life due to the physical, psychological and social impact it entails.   Since about 70% of cases are associated with pain in extremities, these are usually referred to phlebology and lymphology specialists. Treatments to control the edema are not usually successful in reducing the volume of the extremities.   This is in addition to determinants of fashion from the 21st century that demand most women to have slender bodies, while the reality is that overweight and obesity are alarmingly increasing. About 80% of obese patients do not admit to have excess weight, complicating its early diagnosis and prevention of its evolution and, consequently, delaying treatment in patients with this disease.   Due to the clinical presentation and symptoms associated with lipedema, patients are often misdiagnosed with lymphedema, obesity, lipodystrophies or chronic venous insufficiency, and therefore they are not correctly and effectively treated; in the best case scenario, they are administered symptomatic treatments.   In the absence of unified criteria for lipedema, and given the national and international controversy surrounding the term, the Spanish Association of Lymphedema and Lipedema (AEL) has put together a multidisciplinary working group of health professionals from different fields involved in the diagnosis and treatment of this disorder to draft this Consensus Document.   The aim was to answer multiple questions using the documentary evidence and clinical experience available to date.   Is the currently described physiopathology enough to explain lipedema?   Is it a progressive alteration? Does it always get worse?   When you have lipedema, is the progressive increase in body fat percentage normal?   If the main symptom is not the edema: Is manual lymphatic drainage an essential tool for the treatment?   Is it correct to prescribe compression garments in all cases?   What are the most effective treatments?   This working group included the participation of: The Spanish Association of Lymphedema and Lipedema (AEL), the Spanish Chapter of Phlebology and Lymphology (CEFyL) from the Spanish Society of Angiology and Vascular Surgery (SEACV), the Spanish Society of Aesthetic Medicine (SEME), the Spanish Society of Plastic, Reconstructive and Aesthetic Surgery (SECPRE), the Spanish Society of Dietetics and Food Science (SEDCA), the Complutense University of Madrid, and doctors specialized in Physical Medicine and Rehabilitation from the Spanish Society of Rehabilitation and Physical Medicine (SERMEF).   This document includes several chapters on the definition and physiopathology of lipedema, its diagnostic methods, differential diagnosis, classification and treatment using physical, pharmacological and surgical means. It is hoped that it can help people with lipedema and health professionals caring for them.   However, there is still a lot to learn about the etiopathogenesis, diagnosis and treatment of lipedema, so research must continue and be completed with epidemiological studies of its incidence and prevalence, always using an interdisciplinary approach.

Background Lipedema is a chronic disorder presenting in women during puberty or other times of hormonal change such as childbirth or menopause, characterized by symmetric enlargement of nodular, painful subcutaneous adipose tissue (fat) in the limbs, sparing the hands, feet and trunk. Healthcare providers underdiagnose or misdiagnose lipedema as obesity or lymphedema. Materials and methods The benefits (friend) and negative aspects (foe) of lipedema were collected from published literature, discussions with women with lipedema, and institutional review board approved evaluation of medical charts of 46 women with lipedema. Results Lipedema is a foe because lifestyle change does not reduce lipedema fat, the fat is painful, can become obese, causes gait and joint abnormalities, fatigue, lymphedema and psychosocial distress. Hypermobility associated with lipedema can exacerbate joint disease and aortic disease. In contrast, lipedema fat can be a friend as it is associated with relative reductions in obesity-related metabolic dysfunction. In new data collected, lipedema was associated with a low risk of diabetes (2%), dyslipidemia (11.7%) and hypertension (13%) despite an obese average body mass index (BMI) of 35.3 ± 1.7 kg/m2. Conclusion Lipedema is a painful psychologically distressing fat disorder, more foe than friend especially due to associated obesity and lymphedema. More controlled studies are needed to study the mechanisms and treatments for lipedema.

Das Lipödem ist weit mehr als einfach nur dickere und schmerzhafte Beine! Die Erkrankung Lipödem ist mit zahlreichen Mythen behaftet. Im ersten Teil dieser Übersicht werfen wir einen kritischen Blick auf zwei populäre Statements zum Lipödem; Statements, die vor Jahrzehnten schon Eingang in wissenschaftliche Publikationen gefunden haben und seither unkritisch und stetig wiederholt werden; Statements, die inzwischen zum selbstverständlichen Wissensallgemeingut von Lipödempatientinnen und vor allem auch von Lipödem-Selbsthilfegruppen geworden sind. In unserer Darstellung über die Mythen des Lipödems fokussieren wir uns in diesem Beitrag vor allem auf zwei Aspekte, die aufs Engste mit dem Lipödem verbunden sind: auf die Adipositas sowie auf die psychische Situation von Lipödempatientinnen – die wiederum eng mit der Adipositas in Zusammenhang steht. Dabei überprüfen wir zwei häufig publizierte Statements auf wissenschaftliche Evidenz: 1. „Das Lipödem ist eine progrediente Erkrankung”, 2. „Ein Lipödem macht psychisch krank”. Beide Statements widersprechen in hohem Maße unserer seit Jahren bestehenden täglichen klinischen Erfahrung mit diesem speziellen Patientengut. Gleichzeitig haben wir im Rahmen unserer umfangreichen Literaturrecherche festgestellt, dass es auch keine Evidenz für diese in den „Lipödemsprachgebrauch” eingegangenen Behauptungen gibt. Tatsachlich ist das Lipödem in der Regel keine progrediente Erkrankung! Vielmehr liegt bei Lipödempatientinnen häufig eine Gewichtsprogredienz (meist eine Adipositasprogredienz) vor, in deren Folge sich auch das Lipödem verschlechtern kann. Unsere Pilotstudie zum 2. Statement macht deutlich, dass in der Regel nicht das Lipödem Ursache von psychischen Erkrankungen ist. Hier weisen unsere Ergebnisse in die umgekehrte Richtung: Eine – vorbestehende – psychische Vulnerabilität kann ganz wesentlich zum Krankheitsbild Lipödem beitragen. Um das Lipödem in seiner ganzen Komplexität und Vielfalt zu erfassen, braucht es mehr als nur Medizin. Psychosoziale Therapieansätze sollten integraler Bestandteil eines wirksamen multimodalen Behandlungskonzepts sein. Neben den beiden dargestellten Mythen gibt es weitere, die sich um das Lipödem ranken. Diese werden in weiteren Ausgaben dieser Zeitschrift diskutiert werden.
