    Changes in Erythrocyte Sedimentation Rate, White Blood Cell Count, Liver Enzymes, and Magnesium after Gastric Bypass Surgery2011In: Journal of Obesity, ISSN 2090-0708, E-ISSN 2090-0716, Vol. 2011, p. 273105-Article in journal (Refereed)
    Abstract [en]

    Roux-en-Y gastric bypass (RYGBP) is an established method for treatment of obesity, a condition of chronic inflammation with liver steatosis, characterised by increased erythrocyte sedimentation rate (ESR), white blood cell count (WBC), liver enzymes, and decreased magnesium (Mg).We investigated alterations, if any, in ESR, WBC, alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), and Mg after RYGBP. Methods. 21 morbidly obese nondiabetic patients who underwent RYGBP surgery were evaluated preoperatively (baseline), then 1 year (1st followup) and 3.5 years (2nd followup) after RYGBP and compared to an untreated control group. Results. Body mass index, ESR, WBC, ALT, and GGT were all significantly reduced at 1 year in the RYGBP group (30%, 35%, 20%, 45%, and 57%, resp.) while Mg increased by 6%, compared to control group (P = 0.001 − 0.009). Conclusions. Obese patients treated by RYGBP show sustained reductions in ESR, WBC, ALT, and GGTpossibly due to reduced liver steatosis and increased Mg.

    Platelet counts and liver enzymes after bariatric surgery2013In: Journal of Obesity, ISSN 2090-0708, E-ISSN 2090-0716, Vol. 2013, p. 567984-Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Obesity is characterized by liver steatosis, chronic inflammation, and increased liver enzymes, that is, gamma-glutamyltransferase (GGT) and alanine aminotransferase (ALT), markers for nonalcoholic fatty liver disease (NAFLD) and liver fat content. Increased platelet counts (PCs) are associated with inflammatory conditions and are a valuable biomarker of the degree of fibrosis in NAFLD. We investigated alterations in PC, GGT, and ALT after biliopancreatic diversion with duodenal switch (BPD-DS) and Roux-en-Y gastric bypass (RYGBP).

    METHODS: Ten morbidly obese patients (body mass index, BMI: 53.5 ± 3.8 kg/m(2)) who underwent BPD-DS were evaluated preoperatively (baseline) and 1 year (1st followup) and 3 years (2nd followup) after surgery and compared with 21 morbidly obese patients (BMI: 42.3 ± 5.2 kg/m(2)) who underwent RYGBP.

    RESULTS: Over the 3 years of followup, changes in BPD-DS and RYGBP patients (BPD-DS/RYGBP) were as follows: BMI (-44%/-24%), GGT (-63%/-52%), and ALT (-48%/-62%). PC decreased (-21%) statistically significantly only in BPD-DS patients.

    CONCLUSIONS: Morbidly obese patients treated by RYGBP or BPD-DS show sustained reductions in BMI, ALT, and GGT. The decrease in PC and liver enzymes after BPD-DS may reflect a more pronounced decrease of liver-fat-content-related inflammation and, as a result, a lowered secondary thrombocytosis.

    Gastric bypass promotes more lipid mobilization than a similar weight loss induced by low-calorie diet2011In: Journal of Obesity, ISSN 2090-0708, E-ISSN 2090-0716, Vol. 2011, p. 959601-Article in journal (Refereed)
    Abstract [en]

    Background.

    Recently, we found large reductions in visceral and subcutaneous fat one month after gastric bypass (GBP), without any change in liver fat content.

    Purpose.

    Firstly to characterize weight loss-induced lipid mobilization after one month with preoperative low-calorie diet (LCD) and a subsequent month following GBP, and secondly, to discuss the observations with reference to our previous published findings after GBP intervention alone.

    Methods.

    15 morbidly obese women were studied prior to LCD, at GBP, and one month after GBP. Effects on metabolism were measured by magnetic resonance techniques and blood tests.

    Results.

    Body weight was similarly reduced after both months (mean: -8.0 kg, n = 13). Relative body fat changes were smaller after LCD than after GBP (-7.1 ± 3.6% versus -10 ± 3.2%, P = .029, n = 13). Liver fat fell during the LCD month (-41%, P = .001, n = 13) but was unaltered one month after GBP (+12%).

    Conclusion.

    Gastric bypass seems to cause a greater lipid mobilization than a comparable LCD-induced weight loss. One may speculate that GBP-altered gastrointestinal signalling sensitizes adipose tissue to lipolysis, promoting the changes observed.

    Basic Anthropometric Measures in Acute Myocardial Infarction Patients and Individually Sex- and Age-Matched Controls from the General Population2018In: Journal of Obesity, ISSN 2090-0708, E-ISSN 2090-0716, article id 3839482Article in journal (Refereed)
    Abstract [en]

    We compared weight, height, waist and hip circumferences (hip), body mass index (BMI), and waist-to-hip ratio in acute myocardial infarction (MI) patients and individually sex-and age-matched control subjects from the general population in the catchment area of the patients and predicted the risk of MI status by these basic anthropometric measures. The study cohort comprised 748 patients <= 80 years of age with acute MI from a major Swedish cardiac center and their individually sex- and age-matched controls. The analyses were stratified for sex and age (<= 65/>= 66 years). Risk of MI was assessed by conditional logistic regression. A narrow hip in men >66 years was the single strongest risk factor of MI among the anthropometric measures. The combination of hip and weight was particularly efficient in discriminating men >= 66 years with MI from their controls (area under the receiver operating characteristic (AUROC) curve = 0.82). In men <= 65 years, the best combination was hip, BMI, and height (AUROC = 0.79). In women >= 66 years, the best discriminatory model contained only waist-to-hip ratio (AUROC = 0.67), whereas in women <= 65 years, the best combination was hip and BMI (AUROC = 0.68). A narrow hip reasonably reflects small gluteal muscles. This finding might suggest an association between MI and sarcopenia, possibly related to deficiencies in physical activity and nutrition.
