Erythromycin ameliorates renal injury via anti-inflammatory effects in experimental diabetic rats

Aims/hypothesis Recent studies have shown that the inflammatory process is involved in the pathogenesis of diabetic nephropathy. Fourteen-membered ring macrolides, including erythromycin, have anti-inflammatory, as well as antibacterial effects. The aim of this study was to investigate the renoprotective effects of erythromycin in streptozotocin (STZ)-induced diabetic rats.Methods STZ-induced diabetic rats were treated orally with erythromycin (5 mg/kg body weight) or vehicle every day for 8 weeks. To evaluate the effect of erythromycin treatment, we measured urinary albumin excretion, and examined the following in the kidney: histological changes, the expression of intercellular adhesion molecule-1 (ICAM-1), macrophage infiltration, and nuclear factor-kappa B (NF-B) activity.Results Erythromycin significantly reduced urinary albumin excretion without affecting blood glucose levels and blood pressure. Erythromycin also attenuated glomerular hypertrophy, mesangial expansion, macrophage infiltration and ICAM-1 expression in renal tissues. The expression of the gene encoding TGFB1 (also known as TGF-1), type IV collagen protein production and NF-B activity in renal tissues were increased in diabetic rats and reduced by erythromycin treatment.Conclusions/interpretation Erythromycin prevented renal injuries without changes of blood glucose levels and blood pressure in experimental diabetic rats. These results suggest that the renoprotective effects of erythromycin are based on its anti-inflammatory effect via suppression of NF-B activation. Modulation of microinflammation with erythromycin may provide a new approach for diabetic nephropathy.     

国产琥乙红霉素颗粒质量分析

目的综合评价琥乙红霉素颗粒的质量现状。方法采用现行法定标准检验结合探索性研究结果,对市场上14家企业生产的191批琥乙红霉素颗粒的质量进行系统比较,通过对原料药和制剂组分、有关物质、游离红霉素等的考察,结合稳定性和原辅料相容性试验,分析不同企业产品的质量差异。结果法定标准检验191批琥乙红霉素颗粒,合格率为99.5%;探索性研究显示,法定标准中组分、有关物质及游离红霉素检查项的缺失,导致质量控制不到位。结论国内琥乙红霉素颗粒整体质量一般,现行质量标准有待提高。

Inhibitory effects of erythromycin on wear debris-induced VEGF/Flt-1 gene production and osteolysis

Objectives  A highly vascularized and inflammatory periprosthetic tissue augments the progress of aseptic loosening, a major clinical problem after total joint replacement. The purpose of this study is to investigate the effect of erythromycin (EM) on ultra high molecular weight polyethylene (UHMWPE) particle-induced VEGF/VEGF receptor 1 (Flt-1) gene production and inflammatory osteolysis in a mouse model. Methods  UHMWPE particles were introduced into established air pouches on BALB/c mice, followed by implantation of calvaria bone from syngeneic littermates. EM treatment started 2 weeks after bone implantation (5 mg/kg day, i.p. injection). Mice without drug treatment as well as mice injected with saline alone were included. Pouch tissues were harvested 2 weeks after bone implantation. Expression of VEGF, Flt-1, RANKL, IL-1, TNF and CD68 was measured by immunostain and RT-PCR, and implanted bone resorption was analyzed by micro-CT (μCT). Results  Exposure to UHMWPE induced pouch tissue inflammation, increase of VEGF/Flt-1 proteins, and increased bone resorption. EM treatment significantly improved UHMWPE particle-induced tissue inflammation, reduced VEGF/Flt-1 protein expression, and diminished the number of TRAP⁺ cells, as well as the implanted bone resorption. Conclusion  This study demonstrated that EM inhibited VEGF and Flt-1 gene expression. The molecular mechanism of EM action on VEGF/Flt-1 signaling-mediated osteoclastogenesis warrants further investigation.
