Introduction Lower limb lipoedema is a chronic condition of the adipose connective tissue of the skin that affects women. Its frequency is not well known, hence the main objective of this study. Method Retrospective analysis of the records of phlebology consultations in private practice in a single center from April 2020 to April 2021. Inclusion criteria were: women aged 18 to 80 years, presenting with symptoms attributable to veins and the presence of at least one dilated reticular vein. Results The files of 464 patients were analyzed. 7.7% had lipoedema, 3.7% lymphedema, 3% stage 3 obesity. The 36 patients with lipoedema were 54.7±16 years old (mean, Standard Deviation), with a Body Mass Index of 31.3±5.5. Leg pain was the major symptom (32/36) and no patient had a positive pitting test. Conclusion Lipoedema is a frequent condition in phlebology consultations.

The aim of this study was to evaluate alterations in blood parameters after a low-carbohydrate high-fat (LCHF) diet in women with lipedema in comparison to overweight or obese women. A total of 115 women were classified into two groups: the lipedema group and the overweight/obesity group. Both study groups followed the caloric-restricted LCHF diet for 7 months. A total of 48 women completed the study. A reduction in body weight was observed in both study groups. A significant decrease in triglycerides and an increase in HDL-C concentrations were observed in both study groups. Despite the increase in the concentration of LDL-C observed in the lipedema group, changes in LDL-C differed between individual patients. Improvements in liver parameters, glucose tolerance, and a decrease in fasting insulin levels were observed, although they were less pronounced in the lipedema group than in the overweight/obesity group. Kidney and thyroid functions were similar before and after the LCHF diet in both groups. The LCHF diet may be a valuable nutritional strategy for lipedema and overweight/obese women, with a beneficial effect on weight, glucose profile, liver function, the concentration of triglycerides, and HDL-C and with no effect on kidney and thyroid function.

Lipedema is a chronic and progressive disease that may compromise lymphatic function. Although suction-assisted lipectomy (SAL) is considered a safe treatment for lipedema patients, the lymphatic repercussions of this surgical procedure are not fully understood. There is not enough evidence to support the role of SAL in lymphatic function treatment in lipedema. Here, we report a case of lymphatic drainage improvement after lipedema treatment with SAL. Tumescent SAL was performed in the deep subcutaneous layer, preserving the superficial and muscular lymphatic vessels. Pre- and postsurgical lymphoscintigraphy was equally documented under the Genoa protocol. A 34-year-old female patient presented with painful enlargement of the arms and lower limbs caused by lipedema. The patient had undergone conservative treatment with mild improvement in pain and heaviness. Lymphoscintigraphy showed slowed radiotracer progression on the left lower limb, collateral and tortuous lymphatic vessels on the right lower limb, and exuberant radiopharmaceutical concentration on the inguinal chain. Nine months after SAL was performed, the patient underwent another lymphoscintigraphy, which exhibited normalized radiopharmaceutical progression time and normal and symmetrical lymphatic vessel patterns. Collateral lymphatic paths and tortuosity vessels were no longer identified. Furthermore, the patient reported significant improvement in pain and the limb's appearance. Tumescent SAL is not only efficient and safe in treating lipedema, but may also be responsible for improvement in lymphatic drainage in lipedema patients. Additional prospective studies are fundamental to reinforce the current evidence and possibly yield predicting information about the tumescent liposuction eligibility in the improvement of lymphatic drainage.

Background Lipedema is a loose connective tissue disease characterized by a disproportionate accumulation of adipose tissue in the limbs of women. Despite its incidence of 10-20%, lipedema is often underdiagnosed and misdiagnosed. Objectives This review aims to outline current available evidence regarding this enigmatic syndrome and gives a synopsis on the subjects that are still unknown. Materials and Methods PubMed and Embase searches were conducted to identify relevant articles on lipedema pathophysiology, clinical presentation, diagnosis and treatment. Results Lipedema can be considered a disease of the adipocytes or a circulatory disorder of the lymphatics. The relationship between lymphatics and adipose tissue remains controversial. The clinical distinction between lipedema, lymphedema, phlebolymphedema and lipolymphedema can be difficult. Diagnoses often coexist, further complicating the diagnosis of lipedema, which is currently made on clinical grounds alone. The value of diagnostic imaging studies is unclear. Liposuction appears to be an effective treatment and significantly improves symptoms. Conclusion Diagnosing lipedema remains a challenge due to its heterogeneous presentation, co-existing diseases, and the lack of objective diagnostic imaging. Further directions for research include the effect of excess skin resection surgery on lymphatic drainage.

BACKGROUND: Lipedema is a common chronic fat distribution disorder often aligned with pain and reduced quality of life affecting 6-10% of the female population. Although lipedema has acquired more scientific attention in the last decade, validated diagnosis and treatment still remain challenging for specialists. PATIENTS AND METHODS: In this article we evaluate the effect of liposuction on appearance, pain and coexisting diseases of 860 patients with lipedema. Comparison among stages of lipedema pre- and post-liposuction was performed by using t-Tests for independent samples and Kruskal-Wallis-Tests. RESULTS: Our study demonstrates the positive effect on pain reduction in patients with lipedema after liposuction (NRS 2.24) compared with pre-liposuction pain perception (NRS 6.99) and pain perception of patients with conservative treatment (NRS 6.26). Significant differences were shown in the perception between the stages of lipedema and in the reduction of pain perception by liposuction. Furthermore we examined co-diseases in patients with lipedema, primarily menstruation complaints (43%), sleeplessness (36%) and migraine (35%). CONCLUSIONS: A progress of lipedema disease leads not only to a change of appearance and proportion but also to a progressive increase of pain. Liposuction shows a significant effect on pain reduction -independent of the patients' stage of lipedema.

PURPOSE: Lipedema is a painful subcutaneous adipose tissue (SAT) disease involving disproportionate SAT accumulation in the lower extremities that is frequently misdiagnosed as obesity. We developed a semiautomatic segmentation pipeline to quantify the unique lower-extremity SAT quantity in lipedema from multislice chemical-shift-encoded (CSE) magnetic resonance imaging (MRI). APPROACH: Patients with lipedema (n=15) and controls (n=13) matched for age and body mass index (BMI) underwent CSE-MRI acquired from the thighs to ankles. Images were segmented to partition SAT and skeletal muscle with a semiautomated algorithm incorporating classical image processing techniques (thresholding, active contours, Boolean operations, and morphological operations). The Dice similarity coefficient (DSC) was computed for SAT and muscle automated versus ground truth segmentations in the calf and thigh. SAT and muscle volumes and the SAT-to-muscle volume ratio were calculated across slices for decades containing 10% of total slices per participant. The effect size was calculated, and Mann-Whitney U test applied to compare metrics in each decade between groups (significance: two-sided P<0.05). RESULTS: Mean DSC for SAT segmentations was 0.96 in the calf and 0.98 in the thigh, and for muscle was 0.97 in the calf and 0.97 in the thigh. In all decades, mean SAT volume was significantly elevated in participants with versus without lipedema (P<0.01), whereas muscle volume did not differ. Mean SAT-to-muscle volume ratio was significantly elevated (P<0.001) in all decades, where the greatest effect size for distinguishing lipedema was in the seventh decade approximately midthigh (r=0.76). CONCLUSIONS: The semiautomated segmentation of lower-extremity SAT and muscle from CSE-MRI could enable fast multislice analysis of SAT deposition throughout the legs relevant to distinguishing patients with lipedema from females with similar BMI but without SAT disease.

Lipohyperplasia dolorosa (LiDo), also known as lipedema, is a painful subcutaneous adipose tissue disorder. While the characteristic bilateral accumulation of adipocytes in extremities sparing hands and feet is investigated, an objective characterization of pain and the sensory system of LiDo patients is missing. Accordingly, progress to overcome the unsatisfying response to pain-therapeutics of patients of this widespread, lifelong, and severe disease is missing. We characterized the sensory detection profile of painful and non-painful stimuli in 20 non-obese LiDo patients and 20 waist-to-height-ratio matched controls using the clinically approved QST-protocol of the German Research Association on Neuropathic Pain (DFNS e.V.). Further, pain-reports and participants’-psychometry was assessed using the German Pain Questionnaire. LiDo patients showed no overt psychometric abnormalities. LiDo pain appeared as somatic rather than neuropathic or psychosomatic aversive. All QST measurements were normal with the selective exception of two: The pressure pain threshold (PPT) was strongly reduced and the vibration detection threshold (VDT) was strongly increased selectively at the affected thigh. In contrast, sensory profiles at the dorsum of the hand were normal. ROC-analysis of the combination of PPT and VDT of thigh versus hand shows high sensitivity and specificity, categorizing correctly 96.5% of the measured participants as LiDo patients or healthy controls, respectively. Thus, we propose to assess both, PPT and VDT, at the painful thigh and the pain-free hand as basis to develop a combined PVTH-score for differential diagnosis as a fast and convenient bedside test for the identification of non-obese LiDo patients.

In blog posts and other documents, the Lipedema Foundation sometimes presents data on growth in a number of publications in Lipedema research. For example, a statistic we often like to cite is that 50% of primary data papers on Lipedema have been published in the past 5 years. This information can b

Lipedema, lipohypertrophy and secondary lymphedema are three conditions characterized by disproportionate subcutaneous fat accumulation affecting the extremities. Despite the apparent similarities and differences among their phenotypes, a comprehensive histological and molecular comparison does not yet exist, supporting the idea that there is an insufficient understanding of the conditions and particularly of lipohypertrophy. In our study, we performed histological and molecular analysis in anatomically-, BMI- and gender-matched samples of lipedema, lipohypertrophy and secondary lymphedema versus healthy control patients. Hereby, we found a significantly increased epidermal thickness only in patients with lipedema and secondary lymphedema, while significant adipocyte hypertrophy was identified in both lipedema and lipohypertrophy. Interestingly, the assessment of lymphatic vessel morphology showed significantly decreased total area coverage in lipohypertrophy versus the other conditions, while VEGF-D expression was significantly decreased across all conditions. The analysis of junctional genes often associated with permeability indicated a distinct and higher expression only in secondary lymphedema. Finally, the evaluation of the immune cell infiltrate verified the increased CD4+ cell and macrophage infiltration in lymphedema and lipedema respectively, without depicting a distinct immune cell profile in lipohypertrophy. Our study describes the distinct histological and molecular characteristics of lipohypertrophy, clearly distinguishing it from its two most important differential diagnoses.

Introduction: Lipedema is a bilateral enlargement of the legs due to abnormal depositions of subcutaneous fat. Recent studies using lymphoscintigraphy documented that lipedema associates with lymphatic alterations. It is still not known, whether non-lipedema obesity also leads to similar lymphoscintigraphic changes within lower legs. Clinically, both, lipedema and obesity may progress to secondary lymphedema. The aim of the study was to evaluate lymphoscintigraphy of lower limbs in women with lipedema in comparison to overweight/obese women. Methods: 51 women (in the mean age of 43.3 ± 13.56) with the diagnosis of lipedema and 31 women (in the mean age of 44.7 ± 13.48) with overweight/obesity were enrolled into the study. Women in both study groups had no clinical signs of lymphedema. The groups were matched by mean volume of their legs, calculated using the formula for a truncated cone. Lymphoscintigraphy was evaluated in every women qualitatively. Body composition parameters were assessed using bioelectric impedance analysis (BIA). Results: Lymphoscintigraphic alterations within lower extremities were similar in both, lipedema and overweight/obese groups and were present in majority of women in both study groups. The most common lymphoscintigraphic alteration in both groups were additional lymphatic vessels (in the lipedema group observed in 76.5% of patients and in the overweight/obesity group – in 93.5%). Visualization of popliteal lymph nodes and dermal backflow were observed respectively in 33% and in 5.9% in the group with lipedema and in 45.2% and in 9.7% in the overweight/obesity group. There were significant relationships between severity of lymphoscintigraphic alterations and weight, lean body mass (LBM), total body water (TBW), volume of both legs and thigh circumference in the lipedema group. Such relationships were absent in the overweight/obesity group. Discussion: Our study indicates that lymphatic alterations are present before development to clinically visible secondary lymphedema in both conditions, lipedema and overweight/obesity. In majority of women from both study groups they indicate rather an overload of the lymphatic system than insufficiency. Lymphoscintigraphic alterations are similar in both groups, therefore, lymphoscintigraphy is not a diagnostic tool that might distinguish lipedema from overweight/obesity.

Lipoedema is an adipose tissue disorder almost exclusively affecting women. Evidence shows lipoedema is both poorly recognised and misdiagnosed which results in many women struggling to get a diagnosis and to gain access to specialist NHS services. This article aims to raise awareness of lipoedema and highlight the main role that community and primary care nurses can play in identifying this long-term condition earlier. It provides detail on the condition to help signpost, refer for diagnosis and initiate conservative management for those individuals with this challenging condition.

Abstract Lipedema is a wide-spread disease with painful accumulations of subcutaneous fat in legs and arms. Often obesity co-occurs. Many patients suffer from impairment in mobility and mental health. Obesity and mental health in turn can be positively influenced by physical activity. In this study we aimed to examine the interrelations between pain and physical activity on mental health in lipedema patients. In total, 511 female lipedema patients (age M = 40.16 ± 12.45 years, BMI M = 33.86 ± 7.80 kg/m 2 ) filled in questionnaires measuring pain (10-point scale), physical activity (7 Items; units per week), and mental health (PHQ-9; WHOQOL-BREF with subscales mental, physical, social, environmental, and overall health). Response surface analyses were calculated via R statistics. Explained variance was high for the model predicting depression severity (R 2  = .18, p < .001) and physical health (R 2  = .30, p < .001). Additive incongruence effects of pain and physical activity on depression severity, mental, physical, and overall health were found (all p < .001). In our study, physical activity and pain synergistically influenced physical, mental, and overall health. Pain did not only lead to low mental health but also interfered with the valuable potential of engaging in physical activity in lipedema patients.

Background: To define the usefulness of three-dimensional (3D) ultrasound diagnostics for lipedema. Methods and Results: In this study, starting in May 2021, it was decided to apply 3D ultrasound diagnostics in the evaluation of the tissue in 40 patients affected with lipedema (stage I-II-III) who arrived at the Pianeta Linfedema Study Centre. Furthermore, subjects with lipohypertrophy were also included in this study to evaluate the structural features of the adipo-fascia and eventual structural similarity with lipedema. With an adequate instrument (SonoScape 20-3D ultrasound) and probe (17 MHz) on bilateral symmetric marker points, the epidermis-dermis complex and subcutaneous tissue were evaluated. In all patients with lipedema, a normal ultrasound representation of the epidermis-dermis complex, the thickness of subcutaneous tissue, due to hypertrophy of the adipose lobules and of interlobular connective septa, the thickness of the fibers that connect the derma to superficial fascia, and the thickness of the superficial fascia itself as well as of the deep fascia have been highlighted; moreover, fibrotic connective areas in the connective septa that correspond to the palpable nodules has been highlighted. The structural feature, present in all the clinical stages, unexpectedly, was the presence along the superficial fascia of anechogenicity due to the presence of fluid. In lipohypertrophy, structural characteristics similar to those in the initial stage of lipedema have been highlighted. Conclusion: 3D ultrasound diagnostics have led to the discovery of important features of adipo-fascia in lipedema not previously highlighted by two-dimensional ultrasound diagnostic studies.

OBJECTIVE: Symmetrical bilateral lower extremity edema (BLEE) needs to be treated effectively. Finding the cause of this condition increases the success of treatment. Fluid increase in the interstitial space (FIIS) is always present as a cause or a result. Subcutaneously administered nanocolloid is transported by uptake by lymphatic pre-collectors, and this uptake takes place in the interstitium. We aimed to evaluate the interstitium with labeled nanocolloid and contribute to the differential diagnosis in cases with BLEE. METHODS: Our retrospective study included 74 female patients who underwent lymphoscintigraphy for bilateral lower extremity edema. Technetium 99m (Tc-99m) albumin colloid (nanocolloid), a marked colloidal suspension, was applied subcutaneously to two different areas on the dorsum of both feet with a 26 gauge needle The dose volume administered intradermally is approximately 0.2-0.3 ml, and each injector has 22-25MBq of activity. Siemens E-Cam dual-headed SPECT gamma camera was used for imaging. Dynamic and scanning images were taken with a high-resolution parallel hole collimator. Ankle images were re-evaluated by two nuclear medicine specialists, independent of physical examination and scintigraphy findings. RESULTS: 74 female patients with bilateral lower extremity edema were divided into two groups based on physical examination and lymphoscintigraphy findings. There were 40 and 34 patients in Groups I and II, respectively. In the physical examination, patients in Group I were evaluated as lymphedema, and patients in Group II were evaluated as lipedema. The main lymphatic channel (MLC) was not observed in any of the patients in Group I in the early images, and the MLC was observed at a low level in the late imaging in 12 patients. The sensitivity of the presence of distal collateral flows (DCF) in the presence of significant MLC in early imaging in demonstrating increased fluid in the interstitial space (FIIS) was calculated as 80%, specificity as 80%, PPV 80%, and NPV 84%. CONCLUSIONS: While MLC is present in early images, concomitant DCF occurs in cases of lipoedema. The transport of increased lymph fluid production in this group of patients can be covered by the existing MLC. Although MLC is evident, the presence of significant DCF supports the presence of lipedema. It can be used as an important parameter in the diagnosis in early cases where physical examination findings are not evident.

A large and growing body of research suggests that the skin plays an important role in regulating total body sodium, challenging traditional models of sodium homeostasis that focused exclusively on blood pressure and the kidney. In addition, skin sodium may help to prevent water loss and facilitate macrophage-driven antimicrobial host defense, but may also trigger immune dysregulation via upregulation of pro-inflammatory markers and downregulation of anti-inflammatory processes. We performed a systematic search of PubMed for published literature on skin sodium and disease outcomes and found that skin sodium concentration is increased in patients with cardiometabolic conditions including hypertension, diabetes, and end-stage renal disease; autoimmune conditions including multiple sclerosis and systemic sclerosis; and dermatologic conditions including atopic dermatitis, psoriasis, and lipedema. Several patient characteristics are associated with increased skin sodium concentration including older age and male sex. While animal evidence suggests that increased salt intake results in higher skin sodium levels, there are conflicting results from small trials in humans. Additionally, limited data suggest that pharmaceuticals such as diuretics and SGLT-2 inhibitors approved for diabetes, as well as hemodialysis may reduce skin sodium levels. In summary, emerging research supports an important role for skin sodium in physiologic processes related to osmoregulation and immunity. With the advent of new non-invasive MRI measurement techniques and continued research on skin sodium, it may emerge as a marker of immune-mediated disease activity or a potential therapeutic target.

Abstract Background and Aim: Chronic lower extremity edema has been associated with postural impairment, sacroiliac joint dysfunction (SIJD), and abnormal gait. Lymphedema and lipedema are important chronic lower extremity causes. This study aimed to detect the presence of SIJD and postural disorders in patients with lower extremity edema and the relationship between them. Methods: This is a comparative, prospective cohort study. Fifty-three patients with lower extremity edema and 53 healthy subjects were included in the study. Pain provocation tests were used to determine SIJD. Postural analysis was conducted with PostureScreen® Mobile 11.2 (PostureCo, Inc., Trinity, FL) software. The life quality of participants was determined by the Lymphedema Quality of Life (LYMQOL) scale. The functional status of the patients was determined by the Oswestry Disability Index and Lower Extremity Functional Scale. Results: SIJD (18.9%) was more common in the edema group. There was a positive correlation between volume differences, percentages, and the development of SIJD. We found deviations in the head, shoulder, and hip angulations in the edema group. Q angle and lateral shoulder angulation were significantly higher in patients with SIJD in the edema group. In the edema group, LYMQOL-leg total score was higher in patients with SIJD. Conclusion: Chronic lower extremity edema was found to be associated with postural deviations and SIJD. Besides edema control, postural disorders and SIJD should also be considered in these patients.

Lipedema is still a little-known disease, and the internet and social networks have been increasing the identification of many people with the condition, its characteristics, and diagnostic criteria. It is a disease of the adipose tissue that causes changes in body shape in the regions of the body's extremities, hips, and thighs. Classification of lipedema is based on the distribution of adipose tissue and severity of the disease (stages I, II, III, and IV) [ [1] ]. Lymphedema, venous disease, and hypermobile joints are co-morbidities [ [2] ]. Its overlap with overweight and obesity is common. Also, weight fluctuations and metabolic changes stem from body dissatisfaction commonly affecting women.

Background/Aim: YouTube provides information on several health-conditions including lipedema. The aim of this study was to investigate the properties, quality, and quantity of YouTube videos on lipedema. Methods: We explored YouTube using the key word lipedema and the initial top 50 videos were included to review. The properties comprising informers, target, and domains of videos covering number of views, likes, dislikes, duration, viewing rate (VR), and video power index (VPI) were recorded. A modified DISCERN tool and global quality scale (GQS) were used to assess the reliability and quality of videos, respectively. Results: The top 50 videos had a mean of 35,805 views, 282 likes, 12 dislikes, and 30 comments. The mean VPI (96.4) and VR (63.8%) were high. The videos were generally uploaded by health professionals for patient/public and health professional targets with the same ratio (50%). The majority of video contents was related to general information (68%) followed by surgical treatment (62%). Only a small ratio of their content (22%) was about nonsurgical management. The reliability and quality of the videos were intermediate to low. The median DISCERN and GQS scores were higher in the videos uploaded by health professional group compared with nonhealth professionals, but the number of views, VPI, and VR were similar between the groups with regard to the source. Conclusion: YouTube videos on lipedema are mostly provided by health professionals targeting both public/patients and health care providers but the content is limited and the quality and reliability of them were low to intermediate. Therefore, the lipedema specialists are suggested to work together to create up-to-date, high-quality, accessible online educational content to meet the needs of both patients/public and the health professionals. In addition, control mechanisms and careful peer reviewing of the videos informed by nonhealth professionals are warranted to avoid misleading information.

BACKGROUND: Lipedema is a progressive disease, diagnosed most often in women, which is characterized by the unproportionate and symmetrical distribution of adipose tissue primarily in the extremities. Despite numerous results from in vitro and in vivo studies, many questions regarding the pathology and genetic background of lipedema have remained unanswered. METHODS: Adipose tissue-derived stromal/stem cells (ASCs) were isolated from lipoaspirates derived from non-obese and obese lipedema and non-lipedema donors. Growth/morphology, metabolic activity, differentiation potential and gene expression were evaluated using quantification of lipid accumulation, metabolic activity assay, live-cell imaging, RT-PCR, quantitative PCR and immunocytochemical staining. RESULTS: The adipogenic potential of lipedema and non-lipedema ASCs did not rise in parallel with the donors' BMI and did not differ significantly between groups. However, in vitro differentiated adipocytes from non-obese lipedema donors showed significant upregulation of adipogenic gene expression compared to non-obese controls. All other genes tested were equally expressed in lipedema and non-lipedema adipocytes. The ADIPOQ/LEP ratio (ALR) was significantly reduced in adipocytes from obese lipedema donors compared to their non-obese lipedema counterparts. Increased stress fiber-integrated SMA was visible in lipedema adipocytes compared to non-lipedema controls and appeared enhanced in adipocytes from obese lipedema donors. CONCLUSIONS: Not only lipedema per se but also BMI of donors impact adipogenic gene expression substantially in vitro. The significantly reduced ALR and the increased occurrence of myofibroblast-like cells in "obese" lipedema adipocyte cultures underlines the importance of attention towards the co-occurrence of lipedema and obesity. These are important findings towards accurate diagnosis of lipedema.
