The Western diet is rich in salt, and a high salt diet (HSD) is suspected to be a risk factor for cardiovascular diseases. It is now widely accepted that an experimental HSD can stimulate components of the immune system, potentially exacerbating certain autoimmune diseases, or alternatively, improving defenses against certain infections, such as cutaneous leishmaniasis. However, recent findings show that an experimental HSD may also aggravate other infections (e.g., pyelonephritis or systemic listeriosis). Here, we discuss the modulatory effects of a HSD on the microbiota, metabolic signaling, hormonal responses, local sodium concentrations, and their effects on various immune cell types in different tissues. We describe how these factors are integrated, resulting either in immune stimulation or suppression in various tissues and disease settings.

BackgroundLipedema is a loose connective tissue disease predominantly in women identified by increased nodular and fibrotic adipose tissue on the buttocks, hips and limbs that develops at times of hormone, weight and shape change including puberty, pregnancy, and menopause. Lipedema tissue may be very painful and can severely impair mobility. Non-lipedema obesity, lymphedema, venous disease, and hypermobile joints are comorbidities. Lipedema tissue is difficult to reduce by diet, exercise, or bariatric surgery.MethodsThis paper is a consensus guideline on lipedema written by a US committee following the Delphi Method. Consensus statements are rated for strength using the GRADE system.ResultsEighty-five consensus statements outline lipedema pathophysiology, and medical, surgical, vascular, and other therapeutic recommendations. Future research topics are suggested.ConclusionThese guidelines improve the understanding of the loose connective tissue disease, lipedema, to advance our understanding towards early diagnosis, treatments, and ultimately a cure for affected individuals.

Lipedema is a chronic feminine disease that causes abnormal fat deposition in lower limbs and occasionally upper limbs. Easy bruising and pain are common. Lipedema patients suffer from both physical and psychological disability. Despite the relatively high prevalence and the impact on the quality of life, little is known about the disease. The majority of patients are misdiagnosed as lymphedema or obesity. The objective was to perform a non-systematic review on lipedema literature, related to diagnosis and therapy. Regarding pathophysiology, alterations are not exclusively confined to adipose tissue. Lymphatic dysfunction, cardiovascular variations, blood capillary fragility and increased permeability are common. Patients often present with neurological alterations and hormonal malfunction. Elevated cutaneous sodium has been documented. Due to the absence of a defined etiology, evidence-based research is difficult in the management of lipedema. The setting of realistic expectations is important for both patient and medical care provider. The major aims of the management are multimodal for improvements in the quality of life; reduction in heaviness and pain, reshaping the affected limbs, weight control, improvements in mobility. Compression garments, physical therapy, exercise regimens, diet and psychological counseling are necessities. For selected patients, surgical treatment is an added option.

BACKGROUND: Lipedema is characterized by the deposition of abnormal fat in the lower and upper limbs bilaterally. It is a disease with high prevalence and genetic characteristics. Non-specific and non-quantified increases in the thickness of the subcutaneous tissue have previously been demonstrated using magnetic resonance imaging and computed tomography. OBJECTIVES: To evaluate the thickness of the dermis and subcutaneous tissue in predetermined areas as a distinguishing feature between individuals with and without lipedema using ultrasound. METHODS: Ultrasound images of 89 female patients were analyzed, including patients undergoing clinical investigation for venous insufficiency or lipedema who underwent ultrasound evaluations at our institution. Patients were divided in two groups: with lipedema clinically diagnosed and those without lipedema. They underwent a common Doppler protocol for venous mapping to assess venous insufficiency associated with the evaluation of dermis and subcutaneous thickness at pre-defined points of the lower limbs. RESULTS: There were 63 patients with lipedema. Anterior thigh, pre-tibial and lateral aspect of the leg and supra-just medial malleolar region were significantly different. Supra-just medial malleolar region was significantly different with BMI above 25. An optimal cutoff value was calculated for the ultrasound diagnosis of lipedema using thickness of the dermis and subcutaneous tissues. CONCLUSIONS: Studied criteria allow use of simple and reproducible ultrasound cutoff values to diagnose lipedema in the lower limbs. Pre-tibial region thickness measurement, followed by thigh and lateral leg thickness are recommended for the ultrasound diagnosis of lipedema.

This study examined the disease-specific quality of life (QoL) in lipoedema patients undergoing treatment for the condition with liposuction. We conducted a retrospective analysis of all patients (n = 69) who underwent liposuction for treatment of lipoedema between 2004 and 2019, and gathered data on patient age, body mass index, the number of liposuction sessions, and the amount of fat removed per side. The study also prospectively evaluated the QoL in 20 lipoedema patients before and after liposuction using the Freiburg Life Quality Assessment for lymphatic diseases questionnaire. The mean age was 50.6 ± 12.8 years, and the average number of liposuction sessions performed was 2.9 ± 1.9, with a mean volume of 1868 ± 885.5 mL of fat removed per side. Before treatment with liposuction, disease-specific QoL in patients with lipoedema was low on every single subscale as well as on the global score and showed a significant improvement in all aspects after liposuction. There was a significant correlation between a higher number of liposuction treatment sessions and general health status in lipoedema patients (P = .007). Liposuction greatly improves the QoL in lipoedema patients. A higher number of liposuction treatment sessions seem to have a positive effect on general health status in these patients.

Objective: The aim of this study is to investigate the effect of complex decongestive physiotherapy (CDP) plus intermittent pneumatic compression (IPC) applications on upper extremity circumference and volume in patients with lipedema. Methods and Results: All participants included in the study were included in a treatment protocol consisting of CDP and IPC. The Perometer 400 NT was used in the measurement of upper extremity volume and circumference before and after treatment. The measurements were performed in four reference points. According to the Perometer results before and after CDP, statistically significant reduction was found in the circumference of 3 of the 4 points of measurements performed in each of the left and right upper extremities. When the volume assessments were compared, it was seen that statistically significant reduction was found in the volume of both limbs. Conclusion: A treatment program consisting of CDP and IPC can be effective in reducing the circumference and volume of the arm in patients with upper extremity lipedema. So, CDP applications can help prevent the development of complications such as lipolymphedema, hypertension, and heart failure.

AIM: Fluid and macromolecule transport from the interstitium into and through lymphatic vessels is necessary for tissue homeostasis. While lymphatic capillary structure suggests that passive, paracellular transport would be the predominant route of macromolecule entry, active caveolae-mediated transcellular transport has been identified in lymphatic endothelial cells (LECs) in vitro. Caveolae also mediate a wide array of endothelial cell processes, including nitric oxide regulation. Thus, how does the lack of caveolae impact "lymphatic function"? METHODS: Various aspects of lymphatic transport were measured in mice constitutively lacking caveolin-1 ("CavKO"), the protein required for caveolae formation in endothelial cells, and in mice with a LEC-specific Cav1 gene deletion (Lyve1-Cre x Cav1flox/flox ; "LyCav") and ex vivo in their vessels and cells. RESULTS: In each model, lymphatic architecture was largely unchanged. The lymphatic conductance, or initial tissue uptake, was significantly higher in both CavKO mice and LyCav mice by quantitative microlymphangiography and the permeability to 70 kDa dextran was significantly increased in monolayers of LECs isolated from CavKO mice. Conversely, transport within the lymphatic system to the sentinel node was significantly reduced in anaesthetized CavKO and LyCav mice. Isolated, cannulated collecting vessel studies identified significantly reduced phasic contractility when lymphatic endothelium lacks caveolae. Inhibition of nitric oxide synthase was able to partially restore ex vivo vessel contractility. CONCLUSION: Macromolecule transport across lymphatics is increased with loss of caveolae, yet phasic contractility reduced, resulting in reduced overall lymphatic transport function. These studies identify lymphatic caveolar biology as a key regulator of active lymphatic transport functions.

We report on a 29-year-old woman who presented with abdominal right upper quadrant pain after an outpatient liposuction procedure. A contrast-enhanced computed tomography scan revealed 4 hepatic perforation tracts with subcapsular liver hematoma and hematoperitoneum. The patient was treated by intravenous tranexamic acid and isotonic fluids and monitored on an intensive care unit. No intervention or surgery was necessary during her hospital stay. Follow-up imaging after 3 days using contrast-enhanced ultrasound still showed the perforation tracts in the liver but no expansion of subcapsular hematoma. After 7 days, the patient was discharged home with stable hemoglobin and reduced pain. Liver perforation is a rare complication of liposuction procedures. In patients with abdominal pain after liposuction, contrast-enhanced imaging studies should be performed to identify and characterize solid organ injury. Teams with expertise in angiography and visceral surgery need to be on standby.

BACKGROUND: When performing large volume liposuction, perioperative management of lipedema patients with coagulation disorders remains challenging due to a lack of clinical experience. With a prevalence of 1% of von Willebrand disease (VWD) in the general population, basic knowledge on diagnostic and adapted surgical strategies are essential for patients' safety. OBJECTIVE: Based on a selective literature review, the purpose of this article is to present a standardized algorithm for diagnosis and perioperative treatment of VWD patients undergoing large volume liposuction. METHODS: The databases MEDLINE (via PubMed) and Web of Science were selectively searched with the term "(((liposuction) OR (surgery)) OR (lipectomy)) AND (((VWD) OR (hemostaseology)) OR (von Willebrand disease))". Included were articles published in English or German until November 2020. RESULTS: The evidence for large volume liposuctions in patients with VWD is limited. Experience is largely based on operations with similar bleeding risks. A safe performance requires an adjustment of the surgical technique and a customized perioperative drug substitution plan. According to the current literature, perioperative thromboembolic events appear to be rare with adequate drug treatment. CONCLUSION: The implementation of the developed diagnostic and treatment algorithm may help further reducing bleeding complications and improve the safety for treated patients.

Background:  Lipedema is a loose connective tissue disease affecting the limbs of women, that is difficult to lose by diet, exercise, or bariatric surgery. Publications from Europe demonstrate that lipedema reduction surgery improves quality of life for women with lipedema. There are no comparable studies in the United States (USA). The aim of this study was to collect data from women with lipedema in the USA who have undergone lipedema reduction surgery in the USA to determine if quality of life, pain, and other measures improved after lipedema reduction surgery. Methods:  Subjects were recruited and consented online for a 166-item questionnaire in REDCap. In total, 148 women answered the questionnaire after undergoing lipedema reduction surgery in the USA. Significance set at P < 0.05 was determined by ANOVA, Tukey’s multiple comparison test, or paired t-test. Results:  Quality of life improved in 84% and pain improved in 86% of patients. Ambulation improved most in lipedema Stage 3 (96%). Weight loss occurred in all stages by 3 months after surgery. Complications included growth of loose connective tissue within and outside treated areas, tissue fibrosis, anemia, blood clots, and lymphedema. Conclusions:  Women with lipedema noticed significant benefits after lipedema reduction surgery in the USA. Prospective studies are needed to assess benefits and complications after lipedema reduction surgery in the USA.

Lipedema is an infrequently recognized disorder. It is characterized by bilateral painful enlargement of the legs due to abnormal depositions of subcutaneous fat, that can result in considerable disability. The diagnosis is established on the basis of medical history and clinical findings. Early diagnosis of this disorder is necessary to start adapted management and prevent progression and complications of the disease. Currently there is no curative treatment. The conservative treatment requires a multidimensional approach including manual lymph drainage, compression garments and management or prevention of obesity as well as other comorbidities. In some cases, surgery may be considered.

Introduction: Manual lymphatic drainage (MLD), one of the components of complex decongestive physiotherapy, which is accepted as the gold standard in the treatment of lymphedema, is used for therapeutic purposes in many diseases. The most well-known feature of MLD is that it helps to reduce edema. In addition to reducing edema, MLD has many effects, such as increasing venous flow, reducing fatigue, and raising the pain threshold. To the best of our knowledge, there is no study examining the effects of MLD other than its effects on edema in detail. The aim of this study is to compile effects of MLD and to provide a better understanding of the effects of MLD.Methods: A literature search was conducted in Medline, Embase, and the Cochrane Library in July 2019, to identify different effects of MLD. The articles were chosen by, first, reading the abstract and subsequently data were analyzed by reading the entire text through full-text resources. To undertake the study, we have collected information published about different effects of MLD over the last 30 years (1989–2019). According to our results, 20 studies met inclusion criteria.Conclusions: This study suggests that MLD can be used in symptomatic treatment of various diseases (multiple sclerosis, Parkinson's disease) considering the effects of MLD on the systems.

In contrast to obesity, which is very frequent, lipomatosis and lipodystrophy syndromes are rare diseases of adipose tissue. Lipodystrophy syndromes are characterized by metabolic abnormalities associated with partial or generalized lipoatrophy. Lipomatosis is defined by the presence of several body lipomas without lipoatrophy. Dercum’s disease (DD) and Roch-Leri mesosomatous lipomatosis (RLML) are rare and poorly characterized forms of lipomatosis. They have raised little clinical interest despite the non-negligible consequences of DD on quality of life. The main clinical presentation of these diseases includes multiple lipomas, which are painful in DD (in contrast to RLML). The two diseases are frequently associated with obesity and metabolic syndrome, with hypertension, diabetes, or dyslipidemia. The long-term course of the diseases remains poorly described. DD affects mainly women, whereas RLML mostly affects men. In both diseases lipomas are found on the back and thighs, as well as on the abdomen in DD and the forearms in RLML. The painful lipomas tend to recur after surgery in DD (in contrast to RLML). Most cases are sporadic. No specific treatment has been identified, as the pathophysiology remains unknown. Nevertheless, low-grade fat inflammation and specific abnormalities such as hyperbasophilia deserve further investigation. The aim of this review is to analyze the available literature on the topic.
