Online ahead of print.ABSTRACTLipedema is a chronic progressive disease characterized by disproportionate and symmetric adipose tissue accumulation, predominantly affecting women, with upper extremity involvement (Type IV) in approximately 30% of cases. This study aimed to evaluate ultrasound measurements of subcutaneous tissue thickness in the upper extremities of women with lipedema compared with matched controls and to establish diagnostic cutoff values for this region.MethodsCross-sectional case-control study including 102 women (51 with clinically diagnosed lipedema and 51 age- and BMI-matched controls). Bilateral ultrasound measurements were obtained at six standardized anatomical points on the upper extremities, and subcutaneous thickness was measured from the dermal-epidermal junction to the deep fascia. Receiver Operating Characteristic (ROC) curves were used to derive diagnostic cutoff values.ResultsSubcutaneous thickness was significantly greater in the lipedema group at all sites, independent of BMI (p < .05). The mid-arm region (10 cm distal to the axillary line) showed the best diagnostic performance (AUC 0.74; sensitivity 82.4%; specificity 51.9%; cutoff >11.4 mm), and four of the six points demonstrated good accuracy (AUC 0.73-0.74).ConclusionUltrasound using standardized anatomical points and defined cutoff values provides good discriminatory capacity for diagnosing upper extremity lipedema and represents an accessible and reproducible adjunct to clinical assessment.PMID:42527880 | DOI:10.1177/02683555261475099

Biomedicines. 2026 Jul 3;14(7):1510. doi: 10.3390/biomedicines14071510.ABSTRACTBackground: Endometriosis and lipedema are chronic female-predominant disorders characterized by persistent pain that is frequently disproportionate to anatomical lesion burden. Although traditionally interpreted within distinct lesion-centered frameworks, both conditions exhibit striking clinical and epidemiological parallels, including hormonally modulated symptom dynamics, overlap with central pain syndromes, weak correlation between structural disease severity and pain intensity, and symptom clustering during reproductive transitions such as puberty, pregnancy, and menopause. Methods: This study aims to synthesize clinical, molecular, neuroimmune, and endocrine evidence on the interrelationship between endometriosis and lipedema, and to propose a hypothesis-generating neuroimmune framework linking both conditions. This integrative narrative review conducted a non-systematic literature search in PubMed/MEDLINE, Scopus, and Web of Science, focusing on mechanisms related to chronic pain, mast cell biology, TRPV1 signaling, CGRP-mediated neurogenic inflammation, intracrine steroidogenesis, and peripheral and central sensitization. Results: The review identifies convergent biological characteristics between the two diseases, including mast cell activation, macrophage polarization, endothelial dysfunction, fibrosis, angiogenesis, intracrine estrogen metabolism, and persistent inflammatory signaling. In endometriosis, direct evidence demonstrates increased sensory innervation, nerve growth factor expression, TRPV1 sensitization, CGRP-positive fibers, and mast cell-nerve interactions. In lipedema, convergent upstream mechanisms, including mast cell infiltration, elevated histamine levels, adipose tissue inflammation, and local estrogen activation, support the plausibility of a functionally analogous neuroimmune organization, despite incomplete direct neural characterization. In this context, the mast cell-TRPV1-CGRP axis is proposed as a biologically plausible framework, directly supported in endometriosis and currently hypothetical in lipedema, connecting peripheral sensitization, neurogenic inflammation, hormonal chronodependence, and central nociceptive amplification. The model further conceptualizes pain crises as transient events of instability within a sensitized neuroimmune network and proposes mechanistic phenotypes that integrate gastrointestinal, inflammatory, central, and hormonal triggers. Conclusion: Endometriosis and lipedema may represent topographically distinct manifestations of a shared neuroimmune process operating within hormone-sensitive tissues. Although the evidentiary basis remains asymmetric, with stronger mechanistic support in endometriosis than in lipedema, this framework provides a biologically plausible and experimentally testable model integrating endocrine, immune, neural, and vascular contributors to chronic pain amplification. This perspective supports coordinated translational investigation across reproductive biology, endocrinology, and pain medicine and may contribute to future mechanism-based stratification and therapeutic development. This work is hypothesis-generating and is not intended to establish causality or to provide clinical recommendations; all proposed mechanistic and therapeutic inferences require prospective experimental validation.PMID:42511984 | PMC:PMC13403690 | DOI:10.3390/biomedicines14071510

Diseases. 2026 Jul 12;14(7):251. doi: 10.3390/diseases14070251.ABSTRACTBACKGROUND: Lipedema is a chronic disorder that predominantly affects women and is characterized by abnormal subcutaneous adipose tissue accumulation, pain, and vascular dysfunction. However, reliable circulating biomarkers that reflect disease-specific pathophysiology are still lacking. This study investigated serum markers associated with adipose tissue, inflammation, and angiogenesis to further elucidate the pathophysiology of lipedema.METHODS: In this cross-sectional observational study, fasting serum levels of adiponectin, chemerin, lipopolysaccharide-binding protein (LBP), proprotein convertase subtilisin/kexin type 9 (PCSK9), soluble CD163 (sCD163), and soluble CD137 (sCD137)-proteins associated with obesity and inflammation-were measured in 23 premenopausal women with lipedema and 23 age-matched healthy premenopausal controls. Serum endostatin levels, an angiogenesis inhibitor, and insulin-like growth factor binding protein 2 (IGFBP2), a potent proangiogenic factor, were also assessed.RESULTS: Patients with lipedema and obese controls had comparable body mass index, glucose, and serum lipid profiles. No significant differences were observed between groups in circulating levels of adiponectin, chemerin, LBP, PCSK9, sCD163, sCD137 and IGFBP2. In contrast, serum endostatin levels were significantly reduced in patients with lipedema (p = 0.038). Additional analyses demonstrated markedly higher endostatin expression in human subcutaneous adipose tissue than in the liver, suggesting that circulating endostatin levels may be related to adipose tissue mass. However, serum endostatin levels were lower in obese compared with normal-weight women (p < 0.001).CONCLUSION: Lipedema was not associated with altered circulating levels of adiponectin, chemerin, LBP, PCSK9, sCD163, sCD137 or IGFBP2. Reduced serum endostatin levels support a potential role for vascular dysfunction in the pathophysiology of lipedema.PMID:42505579 | PMC:PMC13409243 | DOI:10.3390/diseases14070251

Online ahead of print.ABSTRACTOBJECTIVE: We aimed to evaluate the association between pain, body mass index (BMI), clinical stage, and morphological type in women with lipoedema, using segmental bioimpedance to correlate with clinical symptoms.METHODS: We conducted a cross-sectional observational study of adult women with a confirmed clinical diagnosis of lipoedema. We collected clinical variables, body composition by multifrequency bioimpedance, and pain intensity (VAS 0-10). We examined associations between clinical and biophysical parameters using correlation analyses and group comparisons based on data distribution.RESULTS: Pain was present in most participants, regardless of BMI, clinical stage, or morphological type. Pain showed the strongest associations with touch hypersensitivity and leg heaviness. Bioimpedance measurements indicated notably higher fat accumulation in the lower limbs, while lean mass remained relatively preserved. BMI did not accurately reflect functional severity.CONCLUSIONS: In lipoedema, pain correlates more closely with clinical symptoms such as touch hypersensitivity and leg heaviness than with morphological parameters or BMI; however, these symptoms are nonspecific and should be interpreted as exploratory findings rather than diagnostic markers. Segmental bioimpedance adds descriptive value to clinical stratification and supports multidisciplinary management, while early recognition of lipoedema should continue to rely on established clinical diagnostic criteria.PMID:42497953 | DOI:10.1016/j.jvsv.2026.102585

Aesthetic Plast Surg. 2026 Jul 22. doi: 10.1007/s00266-026-06181-8. Online ahead of print.ABSTRACTWe read with great interest the article on Tranexamic acid use in Liposuction for Lipedema by Bruno and Foti [1]. Evaluating how tranexamic acid affected surgical results and expected blood loss in patients undergoing liposuction for lipedema. The authors provide valuable insights into incidence, prevalence, survival, and diagnostic timelines. However, several methodological considerations merit further discussion. These shortcomings do not undermine the study, but they do suggest the stated treatment effect magnitude may be underestimated. Prospective designs, statistical adjustment for clustering, blinded outcome evaluation, and objective blood loss quantification would all be helpful for future research.No Level Assigned This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Dietary intake was assessed using a validated food frequency questionnaire, and foods were classified according to the NOVA system to determine UPF consumption. The dietary inflammatory index was calculated to assess the inflammatory potential of the diet, and Mediterranean diet adherence was evaluated using a standardized scoring system. Anthropometric measurements, body composition parameters, inflammatory markers, pain intensity (VAS), and physical quality of life (SF-12 PCS) were assessed. Multivariable regression analyses were performed to investigate the associations between dietary variables and clinical outcomes.RESULTS: A total of 86 women with lipedema (stage 1: n = 36, stage 2: n = 33, stage 3: n = 17) were included. UPF consumption increased from 28.1 to 41.3% of total energy and DII scores from +1.46 to +3.02 across stages, while Mediterranean diet adherence decreased from 28.2 to 21.3. In parallel, BMI increased from 27.1 to 31.1 kg/m2 and body fat percentage from 36.7 to 41.1%. Inflammatory markers also rose across stages (hs-CRP: 3.9 to 6.1 mg/L; IL-6: 3.1 to 4.6 pg/ml). In multivariable models, higher DII scores were associated with increased pain severity (β = 0.29, p = 0.007) and higher hs-CRP levels (β = 0.41, p < 0.001), whereas Mediterranean diet adherence was positively associated with physical quality of life (β = 0.34, p = 0.002).CONCLUSION: Higher ultra-processed food consumption and dietary inflammatory potential were associated with increased inflammation, pain, and adiposity, whereas greater Mediterranean diet adherence was associated with better physical quality of life in womendietary inflammatory index, inflammation, lipedema, Mediterranean diet, ultra-processed foods with lipedema.PMID:42453672 | PMC:PMC13364962 | DOI:10.3389/fnut.2026.1846293

Online ahead of print.ABSTRACTObjectivesThe aim of this study was to compare metabolic status and biochemical indices associated with cardiovascular risk, including the triglyceride-glucose (TyG) index, triglyceride-glucose-body mass index (TyG-BMI), and atherogenic lipid indices, between obese individuals with and without lipedema, and to evaluate the potential effect of lipedema on these parameters.Materials and MethodsThis cross-sectional study included 70 obese patients diagnosed with lipedema and 70 obese control individuals without lipedema. Fasting glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglyceride levels were recorded. Based on these parameters, the TyG index, TyG-BMI, atherogenic index of plasma (AIP), atherogenic coefficient (AC), and Castelli risk indices I (CRI-I) and II (CRI-II) were calculated.ResultsNo significant differences were observed between the lipedema and control groups in fasting glucose, total cholesterol, HDL-cholesterol, triglyceride levels, TyG, TyG-BMI, or atherogenic lipid indices (all p > .05). LDL-cholesterol levels were significantly lower in the lipedema group compared with the control group (p = .008). In the lipedema group, TyG-BMI showed a positive correlation with age and BMI, whereas no significant associations were found with symptom duration or pain severity.ConclusionAlthough LDL-cholesterol levels were lower in obese individuals with lipedema, this difference was not reflected in biochemical indices associated with metabolic status and cardiovascular risk. Importantly, metabolic parameters in patients with lipedema accompanied by obesity were comparable to those observed in individuals with obesity alone, suggesting that obesity rather than lipedema may be a more important determinant of metabolic risk in this population. Therefore, metabolic evaluation should not be overlooked in patients with lipedema, and the management of obesity should be considered in treatment planning.PMID:42431189 | DOI:10.1177/02683555261469647

Front Glob Womens Health. 2026 Jun 24;7:1833913. doi: 10.3389/fgwh.2026.1833913. eCollection 2026.ABSTRACTLipedema is a chronic adipose tissue condition that primarily affects women. Despite increasing recognition of lipedema, the condition remains poorly understood and lacks standardized diagnostic criteria or confirmatory tests. Variability in definitions and measurement across clinical and research settings impedes comparability across studies, constraining the evidence base needed to support future advances in clinical practice and patient care. To address challenges associated with inconsistent definitions and data collection, the Lipedema Foundation (LF) partnered with clinicians, researchers, and biostatisticians to develop a Lipedema Common Case Report Form (CCRF). The CCRF was designed to be a research data harmonization tool and is not intended to define diagnostic standards or guide clinical treatment decisions. Its development involved review of published lipedema clinical guidelines and collaborative work to define data elements and attributes for inclusion. When they existed, validated or standardized measures were incorporated directly. When no suitable standardized measures were available, an iterative and collaborative process was used to develop lipedema-specific Common Data Elements (CDEs). The initial version of the CCRF was piloted in participants with and without lipedema, and updates based on participant and clinician feedback were incorporated into the CCRF. A biostatistical review evaluated data completeness, quality, and structure, leading to additional refinements. The final Version 1 instrument consists of 682 CDEs organized into four classifications: (1) Core, (2) Supplemental Highly Recommended, (3) Supplemental, and (4) Exploratory. The current version is prepared for dissemination in the field. By disseminating the CCRF broadly and encouraging adoption in all lipedema research beginning in 2026, including all newly initiated LF-funded projects, LF intends to evaluate its use with grantees and iterate systematically to achieve consistent and comparable data collection. The CCRF provides a structured framework for harmonized data collection that may facilitate comparability across studies and support future development of standardized diagnostic and research methodologies.PMID:42422575 | PMC:PMC13342235 | DOI:10.3389/fgwh.2026.1833913

Aesthetic Plast Surg. 2026 Jul 8. doi: 10.1007/s00266-026-06116-3. Online ahead of print.ABSTRACTINTRODUCTION: Recent research suggests that body contouring surgeries may reduce benzodiazepine (BNZ) use in patients with anxiety or depressive disorders. This study explores whether similar benefits occur in women with lipedema-a chronic adipose disorder causing pain, limited mobility, and psychological distress-who are often prescribed BNZ.MATERIALS AND METHODS: We conducted a retrospective observational study on 100 adult female patients with Stage I-III lipedema undergoing tumescent or water-assisted liposuction between 2019 and 2024. All participants were on stable BNZ therapy for at least six months before surgery. The primary outcome was BNZ usage at six months postoperatively. Secondary outcomes included anxiety (GAD-7), pain (VAS), sleep quality (PSQI), and body image (BODY-Q) and assessed pre- and post-surgery using validated instruments.DISCUSSION: At six months, 77% of patients reduced or discontinued BNZ (32% stopped entirely), with average daily dosage decreasing from 3.2 ± 1.1 to 1.4 ± 1.2 mg (p < 0.001). Statistically significant improvements were also observed in anxiety, pain, sleep quality, and body image (all p < 0.001). Reductions in BNZ use correlated with improvements in pain (r = 0.56), anxiety (r = 0.47), and body image (r = – 0.52). Only minor complications occurred (8%), and no major adverse events were reported.CONCLUSION: Liposuction for lipedema not only improves physical symptoms but also supports psychological recovery, reducing dependence on benzodiazepines. These findings highlight the potential of surgical treatment as part of an integrated approach to managing chronic conditions with both somatic and mental health components. Further research is needed to confirm long-term effects and underlying mechanisms.LEVEL OF EVIDENCE I: Level I, therapeutic study using a properly randomized controlled trial.

Front Cell Dev Biol. 2026 Jun 17;14:1809914. doi: 10.3389/fcell.2026.1809914. eCollection 2026.ABSTRACTLipedema is a chronic adipose tissue disorder characterised by disproportionate accumulation of subcutaneous fat within specific anatomical depots, most commonly the lower extremities, with relative sparing of the trunk. Despite increasing clinical recognition, the mechanisms underlying the selective vulnerability of particular adipose depots and the progressive tissue remodelling observed in lipedema remain poorly understood. Emerging evidence suggests that lipedema is associated with complex alterations in adipocyte biology, adipose stem and progenitor cell (ASPC) function, immune signalling, vascular integrity, extracellular matrix remodelling, and lymphatic homeostasis, indicating that the disease extends beyond simple fat accumulation. Recent advances in adipose tissue biology have demonstrated that adipose depots are not functionally uniform structures, but rather anatomically distinct cellular ecosystems with unique developmental origins, transcriptional programs, stromal composition, immune niches, and metabolic properties. These depot-specific characteristics may provide an important framework for understanding the regional distribution and progression of lipedema. However, while substantial progress has been made in defining differences between visceral and subcutaneous adipose tissue, heterogeneity between individual subcutaneous depots remains comparatively underexplored despite its likely relevance to disorders of regional adipose expansion. The emergence of single-cell and spatial transcriptomic technologies has transformed the study of adipose tissue by enabling high-resolution mapping of adipocytes, stromal populations, vascular cells, and immune microenvironments within healthy and diseased tissue. These approaches offer an unprecedented opportunity to investigate depot-specific cellular states, intercellular signalling networks, and spatial tissue architecture in lipedema. In this review, we synthesise current evidence regarding tissue remodelling and adipose depot heterogeneity in lipedema and examine how single-cell and spatial omics approaches may advance mechanistic understanding of disease pathophysiology. We further discuss current technical and conceptual limitations within the field and highlight future directions for developing integrated adipose tissue atlases capable of identifying disease-driving cellular programs and therapeutic targets in lipedema.PMID:42388970 | PMC:PMC13319045 | DOI:10.3389/fcell.2026.1809914

Online ahead of print.ABSTRACTObjectivesGenerative artificial intelligence (AI) models capable of producing photorealistic medical images are increasingly proposed for patient education, clinical illustration, and trainee instruction. However, their ability to accurately represent anatomically distinct disease subtypes remains unclear. This study evaluated the diagnostic accuracy of a widely used generative AI model in producing images corresponding to the five anatomical lipedema types defined by the Schmeller classification.MethodsIn this prospective audit, ChatGPT’s image-generation interface was prompted to create 60 images for each lipedema type (Types I-V),yielding 300 images. Prompts were standardized and limited to the subtype label without additional descriptors. Two clinicians independently classified each image into one of the five lipedema types or as indeterminate, blinded to the original prompt; disagreements were resolved by a third clinician. Diagnostic performance was assessed using a confusion matrix and per-type sensitivity, specificity, positive predictive value(PPV), negative predictive value (NPV),F1-score,and one-vs-rest receiver operating characteristic area under the curve (ROC AUC). Overall accuracy and Cohen’s κ statistics were also calculated.ResultsAll 300 images were evaluable. The model generated anatomically consistent images for Types I,II, and III (sensitivity = 1.00 for each). Specificity was 1.00 for Types I and II but 0.50 for Type III because all images requested as Types IV and V were classified as Type III. Consequently, the model failed to generate any images consistent with Type IV(arm-predominant) or Type V(calf-isolated) lipedema (sensitivity = 0.00 for both). Overall accuracy was 0.600. Unweighted and quadratic-weighted Cohen’s κ values were 0.500 and 0.667, respectively.

Front Cell Dev Biol. 2026 Jun 17;14:1809914. doi: 10.3389/fcell.2026.1809914. eCollection 2026.ABSTRACTLipedema is a chronic adipose tissue disorder characterised by disproportionate accumulation of subcutaneous fat within specific anatomical depots, most commonly the lower extremities, with relative sparing of the trunk. Despite increasing clinical recognition, the mechanisms underlying the selective vulnerability of particular adipose depots and the progressive tissue remodelling observed in lipedema remain poorly understood. Emerging evidence suggests that lipedema is associated with complex alterations in adipocyte biology, adipose stem and progenitor cell (ASPC) function, immune signalling, vascular integrity, extracellular matrix remodelling, and lymphatic homeostasis, indicating that the disease extends beyond simple fat accumulation. Recent advances in adipose tissue biology have demonstrated that adipose depots are not functionally uniform structures, but rather anatomically distinct cellular ecosystems with unique developmental origins, transcriptional programs, stromal composition, immune niches, and metabolic properties. These depot-specific characteristics may provide an important framework for understanding the regional distribution and progression of lipedema. However, while substantial progress has been made in defining differences between visceral and subcutaneous adipose tissue, heterogeneity between individual subcutaneous depots remains comparatively underexplored despite its likely relevance to disorders of regional adipose expansion. The emergence of single-cell and spatial transcriptomic technologies has transformed the study of adipose tissue by enabling high-resolution mapping of adipocytes, stromal populations, vascular cells, and immune microenvironments within healthy and diseased tissue. These approaches offer an unprecedented opportunity to investigate depot-specific cellular states, intercellular signalling networks, and spatial tissue architecture in lipedema. In this review, we synthesise current evidence regarding tissue remodelling and adipose depot heterogeneity in lipedema and examine how single-cell and spatial omics approaches may advance mechanistic understanding of disease pathophysiology. We further discuss current technical and conceptual limitations within the field and highlight future directions for developing integrated adipose tissue atlases capable of identifying disease-driving cellular programs and therapeutic targets in lipedema.PMID:42388970 | PMC:PMC13319045 | DOI:10.3389/fcell.2026.1809914

However, their ability to accurately represent anatomically distinct disease subtypes remains unclear. This study evaluated the diagnostic accuracy of a widely used generative AI model in producing images corresponding to the five anatomical lipedema types defined by the Schmeller classification.MethodsIn this prospective audit, ChatGPT’s image-generation interface was prompted to create 60 images for each lipedema type (Types I-V),yielding 300 images. Prompts were standardized and limited to the subtype label without additional descriptors. Two clinicians independently classified each image into one of the five lipedema types or as indeterminate, blinded to the original prompt; disagreements were resolved by a third clinician. Diagnostic performance was assessed using a confusion matrix and per-type sensitivity, specificity, positive predictive value(PPV), negative predictive value (NPV),F1-score,and one-vs-rest receiver operating characteristic area under the curve (ROC AUC). Overall accuracy and Cohen’s κ statistics were also calculated.ResultsAll 300 images were evaluable. The model generated anatomically consistent images for Types I,II, and III (sensitivity = 1.00 for each). Specificity was 1.00 for Types I and II but 0.50 for Type III because all images requested as Types IV and V were classified as Type III. Consequently, the model failed to generate any images consistent with Type IV(arm-predominant) or Type V(calf-isolated) lipedema (sensitivity = 0.00 for both). Overall accuracy was 0.600. Unweighted and quadratic-weighted Cohen’s κ values were 0.500 and 0.667, respectively. Micro- and macro-averaged ROC AUC were both 0.750.ConclusionThe model reproduces severity gradients within lower-extremity lipedema but systematically collapses anatomically distinct subtypes into the dominant Type III phenotype, failing to depict arm-predominant and calf-isolated disease. Current generative AI systems may therefore encode lipedema as a single visual phenotype rather than a distributed anatomical entity, limiting their reliability for medical education and clinical communication.PMID:42389893 | DOI:10.1177/02683555261467340

Aesthetic Plast Surg. 2026 Jun 30. doi: 10.1007/s00266-026-06004-w. Online ahead of print.ABSTRACTBACKGROUND: Liposuction is a standard treatment for advanced-stage lipedema, often involving large volumes of tumescent fluid infiltration and aspiration. These shifts raise concerns about postoperative electrolyte imbalances, though systematic data are limited.METHODS: This retrospective single-center study analyzed 116 women with stage 2 or 3 lipedema who underwent liposuction between 2019 and 2023. Pre- and postoperative (within 24 hours) laboratory values including hemoglobin, hematocrit, leukocytes, and electrolytes were compared using paired t-tests, and correlations with clinical variables were assessed.RESULTS: Postoperatively, lower hemoglobin (13.6 ± 0.9 to 11.8 ± 1.2 g/dL, p < .0001) and hematocrit (40.9 ± 2.5 to 35.1 ± 3.5%, p < .0001) levels were observed, alongside higher leukocyte counts (7.6 ± 3.1 to 13.1 ± 5.9 × 109/L, p < .0001). Electrolyte shifts included higher chloride (104.7 ± 2.2 to 106.0 ± 1.9 mmol/L, p < .0001) and slightly lower calcium (2.3 ± 0.1 to 2.2 ± 0.1 mmol/L, p < .0001), sodium (140.8 ± 2.1 to 140.2 ± 2.1 mmol/L, p = .01), and potassium (4.1 ± 0.35 to 4.0 ± 0.4 mmol/L, p = .02). All parameters remained within physiological ranges and were not associated with adverse outcomes. Calcium correlated with hemoglobin (r = 0.49) and hematocrit (r = 0.51) and inversely with aspirate volume (r = -0.41, p = 0.001).CONCLUSIONS: Post-liposuction electrolyte and hematologic changes are mild and clinically insignificant, reflecting predictable hemodilution rather than metabolic disturbance. Routine postoperative testing appears unnecessary for most patients, supporting selective monitoring in those with abnormal baseline values, high aspirate volumes, or relevant comorbidities.LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Online ahead of print.ABSTRACTLipedema is a chronic disorder characterized by disproportionate subcutaneous fat accumulation and pain, with an incompletely understood inflammatory component. It remains unclear whether this inflammatory profile is disease-specific or primarily driven by coexisting adiposity. This study aimed to evaluate systemic inflammatory markers in women with lipedema compared with women with obesity and normal-weight controls. This retrospective study included 229 women aged 30-65 years: 78 with lipedema, 76 with obesity without lipedema, and 75 normal-weight controls. Demographic and laboratory data were obtained from medical records. Inflammatory indices, including the neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic immune-inflammation index, C-reactive protein-to-albumin ratio, and C-reactive protein-albumin-lymphocyte index, were calculated. Group comparisons were performed using one-way analysis of variance with appropriate post hoc tests. Age was similar across groups, whereas body mass index was significantly higher in the lipedema and obesity groups than in controls (p<0.001). The erythrocyte sedimentation rate, C-reactive protein level, and CAR were significantly higher in both the lipedema and obesity groups compared with controls, whereas no significant differences were observed between lipedema and obesity groups. The neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic immune-inflammation index, and C-reactive protein-albumin-lymphocyte index did not differ significantly among groups. Inflammatory indices were generally comparable across lipedema grades. These findings suggest that lipedema is associated with low-grade systemic inflammation; however, its inflammatory profile largely overlaps with obesity, indicating shared inflammatory mechanisms rather than a distinct systemic inflammatory phenotype. Among the evaluated markers, C-reactive protein-based parameters, particularly the C-reactive protein-to-albumin ratio, appeared to better reflect inflammatory burden than hematological composite indices.PMID:42379186 | DOI:10.1055/a-2897-4203

Online ahead of print.ABSTRACTObjectivesThere is a deficiency in awareness and knowledge of lipedema disease among the general public and healthcare professionals. This situation may lead patients to waste time on getting the correct diagnosis and treatment. Currently, information regarding women’s awareness and knowledge level of lipedema in Turkey is limited. This study aims to examine women’s awareness, knowledge level, and desire for information concerning lipedema in Turkey.MethodsA total of 502 volunteer women participated in this online cross-sectional survey study. The survey, constructed by the authors of the study with the assistance of guidelines, systematic reviews, and current literature, consisted of sections aimed at determining demographic data, lipedema awareness, knowledge level, lipedema symptoms and suspicion, as well as individuals’ health behavior and desire for information. The primary outcome of the study was lipedema awareness, which was defined by having previously heard the term lipedema.ResultsDespite 76.1% of participants reporting awareness of lipedema, the average knowledge score about the condition was a low-to-moderate level of knowledge. The vast majority of participants (71.3%) indicated that they were willing to learn more about lipedema, and their preferred source of information was healthcare professionals (80.3%). Yet, only 19 participants (3.8%) think that lipedema is sufficiently regarded within the healthcare system.ConclusionThis study reveals that, despite relatively high awareness of lipedema among women in Turkey, the level of knowledge remains limited. The strong willingness to receive further knowledge and the preference for healthcare professionals as the principal source of information garner attention. However, the low confidence in the recognition of lipedema within the healthcare system may suggest that healthcare professionals have insufficient knowledge or do not prioritize this issue. Improving awareness and knowledge of lipedema among the public and healthcare professionals might facilitate early identification and minimize treatment delays.PMID:42348760 | DOI:10.1177/02683555261464679
