One Anastomosis Gastric Bypass Reconstitutes the Appropriate Profile of Serum Amino Acids in Patients with Morbid Obesity. J Clin Med 2019; 9:jcm9010100. [PMID: 31906073 PMCID: PMC7020034 DOI: 10.3390/jcm9010100] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 12/27/2019] [Accepted: 12/29/2019] [Indexed: 12/27/2022] Open
Abstract
Bariatric surgery leads to metabolic benefits in patients with obesity, but their mechanisms are not well understood. The appropriate composition of serum amino acids (AA) is important for sufficient supply of these components into various tissues and organs. Obesity leads to alterations in serum AA concentrations. The aim of this study was to examine the effect of one anastomosis gastric bypass (OAGB), a promising type of bariatric surgery, on serum AA concentrations, which were assayed by LC-MS in serum of 46 bariatric patients prior to and 6–9 months after OAGB, as well as in 30 lean control subjects. The results were analyzed by principle components analysis and metabolic pathway analysis. PCA analysis showed that OAGB led to normalization of serum AA concentrations of patients with obesity to a pattern similar to the control subjects, and the concentrations of essential AA remained decreased after OAGB. Changes of individual AA and their associated metabolic pathways were also presented. OAGB caused normalization of the AA profile, which may contribute to improvement of glucose homeostasis and reduction of cardiovascular risk. Considering decreased essential AA concentrations after OAGB, increased intake of high protein food should be recommended to the patients after this type of bariatric surgery.

Serum biomarkers of inflammation and adiposity in the LABS cohort: associations with metabolic disease and surgical outcomes. Int J Obes (Lond) 2019; 43:285-296. [PMID: 29777230 PMCID: PMC6240401 DOI: 10.1038/s41366-018-0088-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2017] [Revised: 02/23/2018] [Accepted: 03/12/2018] [Indexed: 12/28/2022]
Abstract
BACKGROUND The utility of serum biomarkers related to inflammation and adiposity as predictors of metabolic disease prevalence and outcomes after bariatric surgery are not well-defined. METHODS Associations between pre- and post-operative serum levels of four biomarkers (C-reactive protein (CRP), cystatin C (CC), leptin, and ghrelin) with baseline measures of adiposity and metabolic disease prevalence (asthma, diabetes, sleep apnea), and weight loss and metabolic disease remission after bariatric surgery were studied in the Longitudinal Assessment of Bariatric Surgery (LABS) cohort. RESULTS Baseline CRP levels were positively associated with the odds of asthma but not diabetes or sleep apnea; baseline CC levels were positively associated with asthma, diabetes, and sleep apnea; baseline leptin levels were positively associated with asthma and negatively associated with diabetes and sleep apnea; baseline ghrelin levels were negatively associated with diabetes and sleep apnea. Increased weight loss was associated with increased baseline levels of leptin and CRP and decreased baseline levels of CC. Remission of diabetes and asthma was not associated with baseline levels of any biomarker. A higher likelihood of asthma remission was associated with a greater decrease in leptin levels, and a higher likelihood of diabetes remission was predicted by a lesser decrease in CC. Bariatric surgery was associated with decreased post-operative CC, CRP, and leptin levels, and increased post-operative ghrelin levels. CONCLUSION This is the largest study to date of serum biomarkers of inflammation and adiposity in a bariatric surgery cohort. Biomarker levels correlate with metabolic disease prevalence prior to bariatric surgery, and with weight loss but not metabolic disease remission after surgery. Bariatric surgery regulates serum biomarker levels in a manner consistent with anti-inflammatory and compensatory orexigenic effects. These data contribute to our understanding of the mechanisms underlying the biologic effects of bariatric surgery.

Abstract
BACKGROUND The recognition of the complications of obesity in various organs and systems should make clinicians and dietitians aware of the importance of early strategies to fight obesity in all age groups. AIM The objective of this study was to evaluate the early effect of using Avena sativa (oat) flour supplement compared to a hypocaloric diet in the management of obesity-related metabolic disorders. MATERIAL AND METHODS Snack was prepared from wholemeal wheat flour (100% extraction) and oat flour. Chemical analysis of the raw materials and the formulae was carried out. 106 obese women with their mean body mass index were 37.73 ± 0.56 kg/m2 volunteered for 8 weeks period. They were divided into two groups; group (A), consumed hypocaloric diet supplemented by the prepared snack, while group (B) subjects followed the low caloric balanced diet. All patients were monitored clinically, anthropometrically, dietary 24 h recall and biochemically. RESULT Data demonstrated significantly decreased in the mean levels of the anthropometric parameters. Group (A) showed a higher decrease in the waist circumference, WHR, body fat% and SBP; while in group (B) weight, BMI, chest circumference and DBP were the most affected parameters. The reduction in the biochemical parameters was higher in the group (A). At the baseline, high values of cystatin-C were found in both groups which may indicate early renal injury. At the end of the study, a significant reduction of the cystatin concentration was observed among both groups (-24.54 & -12.23%). CONCLUSION The healthy effect of the dietary oat supplement on the reduction of central obesity, percentage body fat and different metabolic disorders criteria was confirmed than with hypocaloric diet.

Effect of socio-demographic factors on endogenous biomarkers (cystatin C and creatinine) among elderly chronic kidney disease patients: a cross-sectional study. Int Urol Nephrol 2018. [PMID: 29536424 DOI: 10.1007/s11255-018-1834-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/19/2022]
Abstract
PURPOSE Creatinine is normally used to evaluate kidney function among elderly patients in clinical practice, which has been reported to be affected by socio-demographic factors like BMI and age. Cystatin C a newly introduced biomarker may be more efficient in identifying kidney function in obese and aged CKD patients. The aim of the current study was to assess the effect of BMI on endogenous biomarkers (cystatin C and creatinine) among elderly CKD patients in Malaysia, a first such study in the country. METHODS The current study was conducted at the Hospital University Sains Malaysia, Kelantan. A total of 300 elderly Malay participants ≥ 65 years, with CKD, were taken in study. Demographic data, blood pressure, weight, and height were documented. Serum creatinine was assayed by Chemistry Analyzer Model Architect-C8000 (Jaffe Method), while serum cystatin C was examined by Human cystatin C ELISA kit (Sigma-Aldrich) using Thermo Scientific Varioskan Flash ELISA reader. RESULTS The study participants were divided into three groups on the basis of age. There was a statistically significant difference at the p value < 0.05 in serum creatinine level for the three age groups [F (2, 297) = 1.98, p value 0.045]. Patients were divided into four groups on the basis of BMI. The results of one-way ANOVA revealed a statistically significant difference at the p value < 0.05 in the mean serum creatinine level for the four groups [F (3, 396) = 2.99, p value 0.032]. However, no statistically significant differences between mean serum cystatin C levels were observed on the basis of patient's age and BMI. CONCLUSION Cystatin C is not related to BMI and age among elderly chronic kidney disease patients. The study clearly evaluates the role of serum cystatin C as a good competitor of creatinine among the elderly CKD patients.

Estimated visceral adipose tissue, but not body mass index, is associated with reductions in glomerular filtration rate based on cystatin C in the early stages of chronic kidney disease. Int J Nephrol 2014; 2014:574267. [PMID: 24876964 PMCID: PMC4026990 DOI: 10.1155/2014/574267] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2013] [Revised: 02/03/2014] [Accepted: 03/28/2014] [Indexed: 11/17/2022] Open
Abstract
Information on the association between obesity and initial phases of chronic kidney disease (CKD) is still limited, principally those regarding the influence of visceral adipose tissue. We investigated whether the visceral adipose tissue is more associated with reductions in glomerular filtration rate (GFR) than total and abdominal obesity in hypertensive individuals with stage 1-2 CKD. A cross-sectional study was implemented which involved 241 hypertensive patients undergoing treatment at a primary health care facility. GFR was estimated using equations based on creatinine and cystatin C levels. Explanatory variables included body mass index (BMI), waist circumference (WC), and estimated visceral adipose tissue (eVAT). The mean age was 59.6 ± 9.2 years old and 75.9% were female. According to BMI, 28.2% of subjects were obese. Prevalence of increased WC and eVAT was 63.9% and 58.5%, respectively. Results from the assessment of GFR by BMI, WC, and eVAT categories showed that only women with increased eVAT (≥150 cm(2)) had a lower mean GFR by Larsson (P = 0.016), Levey 2 (P = 0.005), and Levey 3 (P = 0.008) equations. The same result was not observed when the MDRD equation was employed. No association was found between BMI, WC, eVAT, and GFR using only serum creatinine. In the early stages of CKD, increased eVAT in hypertensive women was associated with decreased GFR based on cystatin C.

Abstract
The association of cystatin C with renal function has been studied for more than 25 years. Cystatin C has been described to have a better diagnostic performance than creatinine to assess renal function, particularly to detect small reductions in glomerular filtration rate. Recently, cystatin C has emerged as a strong predictor of incident or recurrent cardiovascular events and adverse outcomes in patients without kidney disease. Furthermore, it has been suggested that cystatin C concentrations are directly related to both inflammation and atherosclerosis. Nevertheless, the link between inflammation, atherogenesis, cardiovascular risk, and cystatin C is still poorly understood. This brief report discusses recent data, contrasting findings and possible mechanisms involved in this interaction.
