Mast cells are immune cells that mediate hypersensi-tivity and allergic reactions in the body, secreting histamine and other inflammatory molecules. They have been associated with different inflammatory conditions such as obesity and other adipose tissue di-sorders. Lipedema is a chronic disease characterized by an abnormal accumulation of adipose tissue on the legs and arms, pain, and other symptoms. Mast cells may play a role in the pathology of lipedema.
Pilot study to determine levels of histamine and its metabolites in lipedema subcutaneous adipose tissue (SAT) biopsy samples, and to test sodium cromoglycate for the treatment of mast cells in women with lipedema.
Biopsies from lipedema and control SAT were collected and analyzed histologically for the presence of mast cells. Mass spec-trometry was used to measure the levels of histamine, a key marker of mast cells, and its metabolites in SAT in women with lipedema and controls, and after a group of women with lipedema were administered oral and topical doses of sodium cromoglycate for two weeks.
Histological examination of biopsies from lipedema patients confirmed the presence of mast cells. Metabolomic analysis revealed high levels of histamine and its metabolites in samples from women with lipedema compared to controls. Following a two-week treatment period, lipedema tissue samples exhibited reduced levels of histamine, suggesting a reduction of mast cell activity.
Sodium cromoglycate has the ability to stabilize mast cells and reduce histamine levels in lipedema patients, which could be useful in lowering the symptoms of lipedema.
肥大细胞是一种免疫细胞,可在体内介导过敏反应和过敏反应,分泌组胺和其他炎症分子。它们与不同的炎症性疾病有关,如肥胖症和其他脂肪组织疾病。脂肪水肿是一种以腿部和手臂异常脂肪堆积、疼痛和其他症状为特征的慢性疾病。肥大细胞可能在脂肪水肿的发病机制中起作用。
初步研究旨在确定脂肪水肿皮下脂肪组织 (SAT) 活检样本中组胺及其代谢物的水平,并测试色甘酸钠治疗脂肪水肿女性肥大细胞的作用。
收集脂肪水肿和对照 SAT 的活检样本,并进行组织学检查以确定肥大细胞的存在。质谱分析用于测量脂肪水肿和对照组女性 SAT 中组胺(肥大细胞的关键标志物)及其代谢物的水平,以及一组脂肪水肿女性接受口服和局部色甘酸钠治疗两周后的水平。
对脂肪水肿患者活检样本的组织学检查证实存在肥大细胞。代谢组学分析显示,与对照组相比,脂肪水肿女性样本中的组胺及其代谢物水平较高。经过两周的治疗期,脂肪水肿组织样本中的组胺水平降低,表明肥大细胞活性降低。
色甘酸钠能够稳定肥大细胞并降低脂肪水肿患者的组胺水平,这可能有助于降低脂肪水肿的症状。
