[PMID: 39262791 PMCID: PMC11387803 DOI: 10.1016/j.isci.2024.110715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2024] [Revised: 06/28/2024] [Accepted: 08/08/2024] [Indexed: 09/13/2024] Open
Abstract
Autoimmune patients have a significantly increased risk of developing coronary artery disease (CAD) compared to the general population. However, autoimmune patients often lack traditional risk factors for CAD and there is increasing recognition of inflammation in CAD development. In this study, we leveraged genome-wide association study (GWAS) data to understand whether there is a genetic relationship between CAD and autoimmunity. Statistical genetic comparison methods were used to identify correlated and causal SNPs between various autoimmune diseases and CAD. Pleiotropic SNPs were identified by cross-phenotype association analysis (CPASSOC) and overlap between GWAS. Causal SNPs were identified using Mendelian Randomization (MR) and Colocalization (COLOC). Using SNP-to-gene mapping, we additionally identified pleiotropic and causal genes and pathways associated between autoimmunity and CAD, which were contextualized by documentation of enrichment in individual cell types identified from coronary atherosclerotic plaques by single-cell RNA sequencing. These results provide insight into potential inflammatory therapeutic targets for CAD.

Yang T, Xie W, Hu F, Cai B. Causal relationship between C-reactive protein and ischemic stroke caused by atherosclerosis: A Mendelian randomization study. J Stroke Cerebrovasc Dis 2024; 33:107873. [PMID: 39009197 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107873] [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: 11/05/2023] [Revised: 07/09/2024] [Accepted: 07/12/2024] [Indexed: 07/17/2024] Open
Abstract
OBJECTIVES This study investigates the association between C-reactive protein (CRP) and ischemic stroke caused by large artery atherosclerosis (LAA). METHODS Five Mendelian Randomization (MR) methodologies were used for two-sample analyses: Inverse Variance Weighting (IVW), MR-Egger regression, Weighted Median (WM), Simple Mode, and Weighted Mode. CRP exposure data were obtained from aggregated summary statistics from a meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry (n = 343,524; UK Biobank). Stroke data were used as the outcome, with specific dataset details for relevant subtypes (cases = 40,585, controls = 406,111). RESULTS In the CRP GWAS dataset, selected single nucleotide polymorphisms (SNPs) as instrumental variables (IVs) showed genome-wide significance and a causal relationship with CRP, particularly in relation to LAA stroke. IVW indicated a robust causal connection between CRP and LAA stroke (Beta = 0.151, SE = 0.055, P = 0.006). The WM approach supported this relationship (Beta = 0.176, SE = 0.082, P = 0.033). However, MR-Egger regression suggested a potential absence of a causal link (Beta = 0.098, SE = 0.077, P = 0.206), with minimal influence from horizontal pleiotropy (Intercept = 0.0029; P = 0.317). The Simple mode found no significant association (Beta = 0.046, SE = 0.217, P = 0.834), while the Weighted mode revealed a significant causal association (Beta = 0.138, SE = 0.059, P = 0.020) between CRP and LAA stroke. CONCLUSIONS MR analysis provides evidence for a potential causal relationship between CRP and an increased risk of LAA stroke.

Egypt Heart J 2024; 76:107. [PMID: 39150613 PMCID: PMC11329460 DOI: 10.1186/s43044-024-00534-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 08/04/2024] [Indexed: 08/17/2024] Open
Abstract
BACKGROUND Cardiac manifestations are infrequently reported in association with celiac disease, but clear link has not been established. The aim of this study was to explore the connection of dilated cardiomyopathy in celiac disease. This systematic review also provides a comprehensive overview of the association between celiac disease and various cardiac manifestations with pathophysiology and management. MAIN BODY We searched PubMed, Cochrane Library, Google Scholar, Embase, Scopus, and Springer nature databases through June 4th 2023 for preferred studies related to our topic using MeSH and Regular keywords. After comprehensive search analysis, data extraction and quality appraisal 19 studies were included in the study. Although results varied across studies, majority of the studies revealed a positive link. Notably, some studies suggested an association between celiac disease and dilated cardiomyopathy, while others did not. These discrepancies could be attributed to differences in methodologies, study populations, and regional variations. Several studies have shown the association of various cardiac manifestations in celiac disease. CONCLUSION Although dilated cardiomyopathy is associated with celiac disease in majority of the studies, there are also studies that conflict with the association. The complex relationship between celiac disease and cardiovascular manifestations potentiates the need for further research with standardized methodologies, larger sample sizes, and consideration of regional variations. Such insights are vital for improving clinical practice by establishing preventive strategies, active screening, early diagnosis, mitigating risks which helps in optimizing cardiovascular health in individuals with celiac disease.

Diabetologia 2024; 67:1630-1641. [PMID: 38772918 PMCID: PMC11343898 DOI: 10.1007/s00125-024-06175-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Accepted: 04/11/2024] [Indexed: 05/23/2024]
Abstract
AIMS/HYPOTHESIS While the association between coeliac disease and type 1 diabetes is well documented, the association of coeliac disease with type 2 diabetes risk remains undetermined. We conducted a nationwide cohort and Mendelian randomisation analysis to investigate this link. METHODS This nationwide matched cohort used data from the Swedish ESPRESSO cohort including 46,150 individuals with coeliac disease and 219,763 matched individuals in the comparator group selected from the general population, followed up from 1969 to 2021. Data from 9053 individuals with coeliac disease who underwent a second biopsy were used to examine the association between persistent villous atrophy and type 2 diabetes. Multivariable Cox regression was employed to estimate the associations. In Mendelian randomisation analysis, 37 independent genetic variants associated with clinically diagnosed coeliac disease at p<5×10-8 were used to proxy genetic liability to coeliac disease. Summary-level data for type 2 diabetes were obtained from the DIAGRAM consortium (80,154 cases) and the FinnGen study (42,593 cases). RESULTS Over a median 15.7 years' follow-up, there were 6132 (13.3%) and 30,138 (13.7%) incident cases of type 2 diabetes in people with coeliac disease and comparator individuals, respectively. Those with coeliac disease were not at increased risk of incident type 2 diabetes with an HR of 1.00 (95% CI 0.97, 1.03) compared with comparator individuals. Persistent villous atrophy was not associated with an increased risk of type 2 diabetes compared with mucosal healing among participants with coeliac disease (HR 1.02, 95% CI 0.90, 1.16). Genetic liability to coeliac disease was not associated with type 2 diabetes in DIAGRAM (OR 1.01, 95% CI 0.99, 1.03) or in FinnGen (OR 1.01, 95% CI 0.99-1.04). CONCLUSIONS/INTERPRETATION Coeliac disease was not associated with type 2 diabetes risk.

Mędza A, Szlagatys-Sidorkiewicz A. Nutritional Status and Metabolism in Celiac Disease: Narrative Review. J Clin Med 2023; 12:5107. [PMID: 37568509 PMCID: PMC10419423 DOI: 10.3390/jcm12155107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 07/20/2023] [Accepted: 08/01/2023] [Indexed: 08/13/2023] Open
Abstract
This review summarizes findings from studies assessing the nutritional status of patients with celiac disease (CD). Malnutrition, including over- and undernutrition, may be present in CD, both at diagnosis and while under treatment. Underweight and growth retardation in children, which mostly reflect malabsorption as a consequence of intestinal inflammation, are not a rule. Clinical presentations of CD can vary widely, and each manifestation has its own characteristics. Evaluating various nutritional parameters can be beneficial for CD patients and may improve health outcomes by facilitating an accurate definition of dietary needs and the development of a balanced diet that not only focuses on eliminating gluten but also provides adequate nutrients, alters metabolism, and reduces the risk of other disorders developing. The cornerstone of CD therapy is a gluten-free diet (GFD), which improves nutritional status, but even on a GFD, features of malnutrition may be present. Additionally, overweight and obesity may occur in patients on a GFD, with typical metabolic consequences.

Abstract
Background: The association of celiac disease (CD) with premature atherosclerosis, including increased carotid artery intima-media thickness and cardiovascular disease (CVD), is controversial. The aim of this study was to investigate this relationship. Methods: Clinical records of patients from Northern Sardinia referred to the Gastroenterology section of the Department of Medicine, University of Sassari, Italy, were analyzed. Unadjusted and adjusted odds ratios (ORs) for CVD with their 95% confidence intervals (CIs) were calculated according to established risk factors, including age, sex, diabetes, dyslipidemia, overweight/obesity, blood hypertension, and cigarette smoking, as well as a possible risk factor such as H. pylori infection. Results: In a total of 8495 patients (mean age 52.1 ± 17.3 years; 64.7% females), 2504 reported a diagnosis of CVD and 632 of CD. Logistic regression analysis showed a significantly reduced risk of CVD among patients with CD (OR 0.30, 95% CI 0.22–0.41). Moreover, the long duration of the gluten-free diet (GFD) was able to lower the risk of CVD in celiac patients. Finally, CD significantly decreased the frequency of carotid plaques (11.8% vs. 40.1%, p < 0.001). Conclusions. Our retrospective study demonstrated that CD reduces the risk of CVD in general and more specifically of carotid lesions after adjusting for potential confounders, especially in those on GFD for a long time.
