Twenty-four-hour ambulatory, but not clinic blood pressure associates with leptin in young adults with overweight or obesity: The African-PREDICT study. Hypertens Res 2024; 47:478-486. [PMID: 37872379 PMCID: PMC10838765 DOI: 10.1038/s41440-023-01477-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 09/11/2023] [Accepted: 10/02/2023] [Indexed: 10/25/2023]
Abstract
Hypertension and obesity are known pro-inflammatory conditions, and limited studies explored various blood pressure modalities and inflammatory markers in young adults with overweight or obesity (OW/OB). We assessed the relationship of clinic and 24 h ambulatory blood pressure with an array of inflammatory markers in young adults with OW/OB. This cross-sectional study included women and men of Black and White ethnicity (n = 1194) with a median age of 24.5 ± 3.12 years. Participants were divided into normal weight and OW/OB groups according to body mass index. Clinic and 24 h ambulatory systolic and diastolic blood pressure were measured. Inflammatory markers included leptin, interleukin-6, interleukin-8, tumour necrosis factor-α, adiponectin, interleukin-10, and C-reactive protein. After adjustments for age, sex, and ethnicity, the OW/OB group had higher blood pressure and an overall worse inflammatory profile compared to the normal weight group (all p ≤ 0.024). In the OW/OB group, 24 h systolic (r = 0.22; p < 0.001) and diastolic blood pressure (r = 0.28; p < 0.001) correlated with leptin, independent of age, sex, and ethnicity. In fully adjusted regression models, 24 h systolic blood pressure (adj.R2 = 0.25; β = 0.28; p = 0.035) and diastolic blood pressure (adj.R2 = 0.10; β = 0.32; p = 0.034), associated with leptin in the OW/OB group and significance remained with additional adjustments for visceral adiposity index. Twenty-four-hour ambulatory, but not clinic blood pressure, is related to leptin in young adults with OW/OB. Leptin shows a stronger relationship with adiposity when compared to other inflammatory markers and may play a role in subcutaneous adiposity-related increased blood pressure.

A data-driven computational model for obesity-driven diabetes onset and remission through weight loss. iScience 2023; 26:108324. [PMID: 38026205 PMCID: PMC10665812 DOI: 10.1016/j.isci.2023.108324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 08/22/2023] [Accepted: 10/20/2023] [Indexed: 12/01/2023] Open
Abstract
Obesity is a major risk factor for the development of type 2 diabetes (T2D), where a sustained weight loss may result in T2D remission in individuals with obesity. To design effective and feasible intervention strategies to prevent or reverse T2D, it is imperative to study the progression of T2D and remission together. Unfortunately, this is not possible through experimental and observational studies. To address this issue, we introduce a data-driven computational model and use human data to investigate the progression of T2D with obesity and remission through weight loss on the same timeline. We identify thresholds for the emergence of T2D and necessary conditions for remission. We explain why remission is only possible within a window of opportunity and the way that window depends on the progression history of T2D, individual's metabolic state, and calorie restrictions. These findings can help to optimize therapeutic intervention strategies for T2D prevention or treatment.

Abstract
Complement factor 5 of the innate immune system generates C5a and C5b ligands, which initiate inflammatory and cell lysis events, respectively. C5 activation has been linked with obesity-associated metabolic disorders; however, whether it has a causative role is unclear. We generated a C5 null (C5-/-) mouse using CRISPR-Cas9 gene editing to determine whether loss of C5 improves obesity-linked metabolic dysfunction. Generation of a new mouse model was prompted in part by the observation of off-target gene mutations in commercially available C5-/- lines. Male and female wild-type (WT), heterozygous (Het), and C5-/- mice were fed low-fat diet (LFD) or high-fat diet (HFD) for 22 wk. Body weight gain did not differ between genotypes on LFD or HFD. In lean animals, male C5-/- mice had similar glucose tolerance compared with WT controls; however, in obese conditions, glucose tolerance was worsened in C5-/- compared with controls. In contrast, female mice did not exhibit differences in glucose tolerance between genotypes under either dietary paradigm. Fasting insulin was not different between genotypes, whereas diet-induced obese male C5-/- mice had lower fed insulin concentrations compared with WT controls. No differences in adipose tissue inflammation or adipocyte size were identified between groups. Similarly, susceptibility to fatty liver and hepatic inflammation was similar between WT and C5-/- mice. However, the systemic cytokine response to acute endotoxin exposure was decreased in C5-/- mice. Together, these data suggest that loss of C5 worsens glucose tolerance in obese male but not female mice. Additional work is required to pinpoint the mechanisms by which loss of C5 amplifies glucose intolerance in obesity.NEW & NOTEWORTHY We generated a new mouse model of complement factor 5 deficiency. This work was prompted by a need for improved transgenic mouse lines of C5, due to off-target gene mutations. We find that loss of C5 worsens glucose tolerance in a sex-dependent manner. Though the mechanisms evoking glucose intolerance are not clear, we are confident this model will be useful in interrogating complement activation in obesity-associated diseases.

Abstract
OBJECTIVE The aim: To determine the features of daily shifts in blood pressure (BP), the influence of the presence of rheumatoid arthritis (RA) on BP control and identify factors that affect BP among patients with RA in combination with resistant hypertension (RH). PATIENTS AND METHODS Materials and methods: All material for writing this scientific work were the results of a comprehensive survey of 201 people with RH and RA, hypertension (H) and RA, RA without H, H without RA and relatively healthy individuals. A laboratory study was performed: rheumatoid factor, C-reactive protein (CRP), K+ serum, and creatinine levels. All patients underwent office BP measurement and ambulatory BP monitoring for 24 hours. Statistical processing of the study results was carried out using "IBM SPSS Statistics 22". RESULTS Results: Among patients with RA in combination with RH non-dippers (38.7%) are the most common type of BP profile. Patients with RH in combination with RA are characterized by an increase in BP more at night (p <0.003), which corresponds to the high frequency of night-peackers (17.7%). The presence of RA determines worse control of diastolic BP (p <0.01) and more vascular overload on organs and systems during the night (p <0.05). CONCLUSION Conclusions: An increase in BP in patients with RA in combination with RH is more significant at night, characterized by poorer BP control and greater vascular load at night indicating the need for tighter control of BP during sleep. Non-dippers are most often detected among patients with RA in combination with RH, which is prognostically unfavorable for the development of nocturnal "vascular accidents".

Abstract
Purpose Assessing an individual's systemic inflammatory state is vital to understand inflammation's role in cardiometabolic diseases and identify those at the greatest risk of disease. We generated global inflammation scores and investigated their associations with cardiometabolic risk factors and adverse outcomes. Patients and Methods Aggregate Inflammation Scores (AIS) and Principal Component Analysis (PCA) scores were generated for 7287 Framingham Heart Study participants using up to 26 inflammation-related proteins, with higher scores reflecting a pro-inflammatory milieu. Multivariable regression and proportional hazards analyses were conducted to investigate the associations of inflammation with cardiometabolic risk factors and outcomes. The primary outcomes for cross-sectional analyses included age, cigarette smoking, fasting lipid and glucose levels, blood pressure, body mass index (BMI), and hypertension, diabetes, and obesity. For prospective analyses, new-onset hypertension, diabetes, obesity, cardiovascular disease and all-cause mortality were investigated. Results Higher inflammation scores were associated with smoking and older age, higher BMI, systolic blood pressure, lipids, and glucose levels, and with greater odds of hypertension and diabetes after adjusting for age, sex, cohort, and BMI (all p < 0.001). Higher baseline scores were associated with greater odds of new-onset hypertension after adjusting for traditional risk factors (OR [95% CI] per one standard deviation [1-SD] increase, AIS: 1.33 [1.21-1.47], PCA score: 1.26 [1.12-1.42], p < 0.001). The AIS also was associated with new-onset diabetes (1.32 [1.14-1.52], p < 0.001). Proportional hazards analyses revealed greater risk of new-onset cardiovascular disease events and all-cause mortality (HR [95% CI] per 1-SD, AIS: 1.25 [1.14-1.37] and 1.32 [1.23-1.42], PCA score: 1.22 [1.13-1.33] and 1.40 [1.31-1.49], p < 0.001). Conclusion Global inflammation scores encompassing an array of pro- and anti-inflammatory proteins and pathways may enhance risk assessment for cardiometabolic diseases. The AIS and PCA scores provide further opportunities to investigate the mechanisms of inflammation-related risk of disease.

Abstract
BACKGROUND AND AIM Fecal microbiome disturbances are linked to different human diseases. In the case of obesity, gut microbiota seems to play a role in the development of low-grade inflammation. The purpose of the present study was to identify specific bacterial families and genera associated with an increased obesity-related inflammatory status, which would allow to build a regression model for the prediction of the inflammatory status of obese and overweight subjects based on fecal microorganisms. METHODS A total of 361 volunteers from the Obekit trial (65 normal-weight, 110 overweight, and 186 obese) were classified according to four variables: waist/hip ratio (≥0.86 for women and ≥1.00 for men), leptin/adiponectin ratio (LAR, ≥3.0 for women and ≥1.4 for men), and plasma C-reactive protein (≥2 mg/L) and TNF levels (≥0.85 pg/mL). An inflammation score was designed to classify individuals in low (those subjects who did exceed the threshold value in 0 or 1 variable) or high inflammatory index (those subjects who did exceed the threshold value in 2 or more variables). Fecal 16 S rRNA sequencing was performed for all participants, and differential abundance analyses for family and genera were performed using the MicrobiomeAnalyst web-based platform. RESULTS Methanobacteriaceae, Christensenellaceae, Coriobacteriaceae, Bifidobacteriaceae, Catabacteriaceae, and Dehalobacteriaceae families, and Methanobrevibacter, Eggerthella, Gemmiger, Anaerostipes, and Collinsella genera were significantly overrepresented in subjects with low inflammatory index. Conversely, Carnobacteriaceae, Veillonellaceae, Pasteurellaceae, Prevotellaceae and Enterobacteriaceae families, and Granulicatella, Veillonella, Haemophilus, Dialister Parabacteroides, Prevotella, Shigella, and Allisonella genera were more abundant in subjects with a high inflammatory index. A regression model adjusted by BMI, sex, and age and including the families Coriobacteriaceae and Prevotellaceae and the genus Veillonella was developed. CONCLUSION A microbiota-based regression model was able to predict the obesity-related inflammatory status (area under the ROC curve = 0.8570 ± 0.0092 Harrell's optimism-correction) and could be useful in the precision management of inflammobesity.

Abstract
BACKGROUND The cytokine tumor necrosis factor-alpha (TNF-α) is elevated in resistant hypertension (RH), but the effects of a TNF-α inhibitor in this population is unknown. OBJECTIVE The aim of this trial was to evaluate whether a single dose of infliximab controlled by placebo acutely reduces blood pressure (BP) in RH subjects. METHODS A double-blind, placebo-controlled, crossover trial was conducted, and randomized RH subjects received either infliximab or placebo. The primary endpoint was the change in mean BP levels relative to the baseline immediately after the infusion obtained by continuously beat-to-beat non-invasive hemodynamic assessment. Secondary endpoints included changes in office, ambulatory and central BP measurements; endothelial function; and inflammatory biomarkers after 7 days. The level of significance accepted was alpha=0.05. RESULTS Ten RH subjects were enrolled. The primary endpoint analysis showed an acute decrease in mean BP values (mean of differences ± standard deviation = -6.3 ± 7.2 mmHg, p=0.02) from baseline, after the application of infliximab compared with placebo. Diastolic BP levels (-4.9 ± 5.5 mmHg, p=0.02), but not systolic BP levels (-9.4 ± 19.7 mmHg, p=0.16), lowered after infliximab infusion. No further significant differences were identified in either the other hemodynamic parameters or in secondary endpoints, except for TNF-α levels, which increased continuously after infliximab infusion. No adverse events were reported during the protocol. CONCLUSIONS A single-dose of infliximab decreased the mean and diastolic BP levels immediately after its infusion, when compared to the placebo in RH. The anti-TNF-α therapy was found to be safe and well-tolerated. The results of this proof-of-concept are hypothesis-generating and need to be further investigated.

Long-term whole-grain rye and wheat consumption and their associations with selected biomarkers of inflammation, endothelial function, and cardiovascular disease. Eur J Clin Nutr 2020; 75:123-132.

Abstract
BACKGROUND/OBJECTIVES Whole-grain (WG) intake has been associated with a lowered risk of developing type 2 diabetes, cardiovascular disease, and some cancers in epidemiological studies. Reduced subclinical inflammation could be one important mechanism behind such associations. This study investigated whether high long-term WG rye and wheat intakes were associated with lower concentrations of biomarkers of inflammation, endothelial function, and protein biomarkers associated with cardiovascular disease. SUBJECTS/METHODS We assessed WG intake by food frequency questionnaire (FFQ) and by measuring alkylresorcinols (ARs) in plasma and adipose tissue, respectively. Selected biomarkers in free-living 109 women and 149 men were analyzed from two clinical subcohort studies (Swedish Mammography Cohort-Clinical (SMC-C) and Cohort of Swedish Men-Clinical (COSM-C), respectively. Total WG rye and wheat (WGRnW) and the ratio of WG rye to WG rye and wheat (WGR/WGRnW) were estimated from FFQs. ARs were measured in plasma and adipose tissue by gas chromatography-mass spectrometry (GC-MS) and the biomarkers by ELISA. RESULTS We found no consistent associations between WG intake assessed by different methods and the selected biomarkers. However, WGRnW intake was inversely associated with cathepsin S (P-trend < 0.05) and total AR and C17:0/C21:0 in plasma were inversely associated with the endostatin concentration (P-trend < 0.05) adjusted for BMI, age, and sex. CONCLUSION The results give limited support to the hypothesis that a high WG wheat and rye intake is associated with lower concentrations of common biomarkers of inflammation and CVD that have previously been reported inversely associated with WG intake or an overall healthy lifestyle.

Abstract
PURPOSE OF REVIEW To gather data from studies evaluating the pro-inflammatory profile of individuals with resistant hypertension (RH), and bring a clinical update of new and potential complementary therapies to treat inflammation in RH. RECENT FINDINGS Increases in pro-inflammatory cytokines are related to elevated blood pressure and target organ damage in RH patients. Clinical and experimental studies have shown that some biological therapies, especially TNF-α inhibitors, regulated pro- and anti-inflammatory cytokines associated with improvements in clinical outcomes, although they are not yet reported in RH. New emerging therapies to treat inflammation in RH, although promising, are still hypotheses that have not been scientifically confirmed in clinical trials. For this reason, inflammation-target treatments, such as the TNF-α and IL-6 inhibitors, should be encouraged for testing as complementary therapies in RH in order to elucidate their potential benefits.
