Lee WC, Chen JB, Moi SH, Yang CH. Association of proportion of the HDL-cholesterol subclasses HDL-2b and HDL-3 and macrovascular events among patients undergoing hemodialysis. Sci Rep 2021; 11:1871. [PMID: 33479451 PMCID: PMC7820459 DOI: 10.1038/s41598-021-81636-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 01/07/2021] [Indexed: 12/14/2022] Open
Abstract
Altered high-density lipoprotein cholesterol (HDL-C) subclass distribution in hemodialysis (HD) patients is well documented. Aim of this study is to investigate the relationship between HDL-C subclass distribution and macrovascular events in patients undergoing HD. A total of 164 prevalent HD patients and 71 healthy individuals in one hospital-facilitated clinic were enrolled from May 2019 to July 2019 and individual HD patients was follow-up for one year. Macrovascular events (cerebral stroke, coronary heart disease) were recorded in the study period. The HDL-2b, HDL-3 proportions and biochemical parameters were measured. Pearson correlation test and logistic regression analysis were used to examine correlation and odds ratio (OR). 144 HD patients completed one-year follow-up. Cohort with macrovascular events revealed significantly lower HDL-2b and higher HDL-3 subclass proportions compared to those without events. By multivariable adjustment, HDL-3 subclass proportion revealed significantly increase risk for these events (OR 1.17, 95% CI 1.02–1.41, P = 0.044). HDL-2b subclass was significantly higher and HDL-3 subclass was significantly lower in the HD cohort under the hs-CRP level of < 3 mg/L compared to higher hs-CRP level. In conclusion, HDL-2b and HDL-3 subclasses distributions were associated with macrovascular events in HD patients. Proinflammatory status influences the distribution of HDL-2b and HDL-3 subclasses in HD patients.

Deng L, Ou Z, Huang D, Li C, Lu Z, Liu W, Wu F, Nong C, Gao J, Peng Y. Diverse effects of different Akkermansia muciniphila genotypes on Brown adipose tissue inflammation and whitening in a high-fat-diet murine model. Microb Pathog 2020; 147:104353. [PMID: 32592821 DOI: 10.1016/j.micpath.2020.104353] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 03/10/2020] [Accepted: 06/11/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The purpose of this study was to investigate the differences in the metabolic protective effects of Akkermansia muciniphila (A.muciniphila) genotypes on high-fat diet mice and explore possible mechanisms. METHODS Male C57BL/6 mice were randomly divided into 6 groups, including high-fat diet (HFD)+ A. muciniphila I/II/PBS group, normal control diet (NCD)+ A. muciniphila I/II/PBS group, respectively. Dietary intervention and A. muciniphila gavage were performed simultaneously. Blood glucose and lipid metabolism, brown adipose morphology and activities, and intestinal barrier function were examined after the mice were sacrificed. RESULTS A.muciniphila gavage improved the impaired glucose tolerance, hyperlipidemia and liver steatosis in HFD mice, and that A. muciniphila II (Amuc_GP25) was not as effective as A. muciniphila I (Amuc_GP01). This phenomenon might be because Amuc_GP01 intervention significantly inhibited brown adipose tissue whitening and inflammation induced by HFD, by repairing the intestinal barrier and relieving endotoxemia. Amuc_GP25 did not display the same results as Amuc_GP01 in HFD mice but had stronger effects in the NCD mice. CONCLUSIONS This study reveals the distinct functions of different A. muciniphila genotypes on diet-induced obesity, suggesting that different A. muciniphila genotypes may affect pathological conditions differently through distinct action pathways.
