Proposed Framework for Research Case Definitions of Lipedema.

Background: Our aim is to propose a framework for the development of a research case definition of lipedema, based on current available literature and those observations that can be applied to future lipedema research with the intent to standardize and strengthen the scientific evidence base. Methods and Results: We conducted a narrative review of the literature, and identified consensus characteristics and disputed characteristics that could be included in a research case definition of lipedema. After considering the strength of the evidence and how each characteristic might be measured in a research study, we recommended an approach for the development of a research case definition of lipedema that would be based on consideration of five agreed-upon characteristics, and five disputed, or less substantiated, characteristics as additional evidence to enhance specificity. Conclusions: We present a case definition framework for lipedema drawn from the scientific literature that can be applied to future studies on lipedema. Utilizing this framework should help to increase the sensitivity and specificity of case definition and provide an opportunity for meta-analysis of clinical studies and facilitate future research intercomparisons.

Body mass index vs. waist-to-height-ratio in patients with lipohyperplasia dolorosa (vulgo lipedema).

BACKGROUND: Lipedema, also known as lipohyperplasia dolorosa (LiDo), is a painful condition affecting women, causing a disproportionate accumulation of subcutaneous adipose tissue in the extremities. It carries a lower risk of diabetes and cardio-metabolic dysfunctions compared to obesity, but coincident obesity can complicate diagnosis and treatment. PATIENTS AND METHODS: This retrospective study included 607 female LiDo patients, ≥ 18 years, stage 1-3, from Germany, the UK, and Spain. Data were collected as part of the standard initial assessment for LiDo patients. RESULTS: Based on waist-to-height-ratio (WHtR), 15.2% of patients were underweight, 45.5% normal weight, 22.1% overweight and 17.3% obese. There was a significant association between WHtR category and age group. Body mass index (BMI) is often overestimated, leading to misdiagnosis of obesity. CONCLUSIONS: The use of BMI also affects the recent decision of the German Federal Joint Committee on the reimbursement of liposuction costs by health insurance funds. Patients with BMI of more than 40 kg/m2 are excluded from cost coverage, and those with BMI between 35 kg/m2 and 40 kg/m2 must first receive conservative obesity therapy. In conclusion, the sole use of BMI in lipedema is unreliable and, in contrast to WHtR, leads to inaccurate diagnoses overestimating overweight and obesity.

[Obesity and secondary lymphedema]. / Adipositas und sekundäres Lymphödem.

Obesity causes all types of lymphedema to deteriorate. Obesity-associated lymphedema is by now the most frequent secondary lymphedema and constitutes an entity in its own right. Obesity and its comorbidities, due to mechanical and inflammatory effects, decrease lymphatic transport and create a vicious circle of lymph stasis, local adipogenesis, and fibrosis. The therapeutic strategy must therefore address both lymphedema and obesity and its comorbidities.

Clinical outcome of short-term compression after sclerotherapy for telangiectatic varicose veins.

BACKGROUND: Sclerotherapy is considered to be the method of choice for the treatment of telangiectatic varicose veins (C1 veins). Whereas the use of compression stockings after sclerotherapy is recommended, little is known about the impact of compression on the outcome of sclerotherapy. The aim of this study was to assess the influence of compression on the outcome of injection sclerotherapy of C1 varicose veins. METHODS: There were 100 legs of 50 consecutive patients with chronic venous insufficiency (C1) included. After randomization per patient, both legs were treated with sclerotherapy in a predefined area of the thigh (measuring 100 cm2), followed by eccentric compression for 24 hours. Group A received no further compression, whereas group B was additionally equipped with compression stockings of 18 to 20 mm Hg above the ankle and continued wearing these for 1 week. Photodocumentation was performed before, 1 week after, and 4 weeks after sclerotherapy, and the clinical outcome was assessed at these postprocedure follow-up dates. The photographs were reviewed by an internal unblinded rater and an independent blinded external rater. RESULTS: There was no discernible difference between the groups in terms of clinical outcome or side effects after 4 weeks. Whereas inter-rater reliability was high, there was no correlation between the raters and patients in terms of outcome. In 55% of the treated legs, the patients deemed the result of the treatment to be good; in 27% of the treated legs, fair; and in 18%, poor. Postprocedure hyperpigmentation occurred in 13% of patients and was comparable in both groups. Compression therapy was found to be comfortable by the majority (58%) of patients. CONCLUSIONS: One week of postinterventional compression therapy had no clinical benefit compared with no compression.

S1 guidelines: Lipedema.

The present, revised guidelines on lipedema were developed under the auspices of and funded by the German Society of Phlebology (DGP). The recommendations are based on a systematic literature search and the consensus of eight medical societies and working groups. The guidelines contain recommendations with respect to diagnosis and management of lipedema. The diagnosis is established on the basis of medical history and clinical findings. Characteristically, there is a localized, symmetrical increase in subcutaneous adipose tissue in arms and legs that is in marked disproportion to the trunk. Other findings include edema, easy bruising, and increased tenderness. Further diagnostic tests are usually reserved for special cases that require additional workup. Lipedema is a chronic, progressive disorder marked by the individual variability and unpredictability of its clinical course. Treatment consists of four therapeutic mainstays that should be combined as necessary and address current clinical symptoms: complex physical therapy (manual lymphatic drainage, compression therapy, exercise therapy, and skin care), liposuction and plastic surgery, diet, and physical activity, as well as psychotherapy if necessary. Surgical procedures are indicated if - despite thorough conservative treatment - symptoms persist, or if there is progression of clinical findings and/or symptoms. If present, morbid obesity should be therapeutically addressed prior to liposuction.

S1-Leitlinie Lipödem.

Die vorliegende überarbeitete Leitlinie zum Lipödem wurde unter der Federführung der Deutschen Gesellschaft für Phlebologie (DGP) erstellt und finanziert. Die Inhalte beruhen auf einer systematischen Literaturrecherche und dem Konsens von acht medizinischen Fachgesellschaften und Berufsverbänden. Die Leitlinie beinhaltet Empfehlungen zu Diagnostik und Therapie des Lipödems. Die Diagnose ist dabei auf der Basis von Anamnese und klinischem Befund zu stellen. Charakteristisch ist eine umschriebene, symmetrisch lokalisierte Vermehrung des Unterhautfettgewebes an den Extremitäten mit deutlicher Disproportion zum Stamm. Zusätzlich finden sich Ödeme, Hämatomneigung und eine gesteigerte Schmerzhaftigkeit der betroffenen Körperabschnitte. Weitere apparative Untersuchungen sind bisher besonderen Fragestellungen vorbehalten. Die Erkrankung ist chronisch progredient mit individuell unterschiedlichem und nicht vorhersehbarem Verlauf. Die Therapie besteht aus vier Säulen, die individuell kombiniert und an das aktuelle Beschwerdebild angepasst werden sollten: komplexe physikalische Entstauungstherapie (manuelle Lymphdrainage, Kompressionstherapie, Bewegungstherapie, Hautpflege), Liposuktion und plastisch-chirurgische Interventionen, Ernährung und körperliche Aktivität sowie ggf. additive Psychotherapie. Operative Maßnahmen sind insbesondere dann angezeigt, wenn trotz konsequent durchgeführter konservativer Therapie noch Beschwerden bestehen bzw. eine Progredienz des Befundes und/oder der Beschwerden auftritt. Eine begleitend zum Lipödem bestehende morbide Adipositas sollte vor einer Liposuktion therapeutisch angegangen werden.
