Factors associated with dyslipidemia and its prevalence among Awash wine factory employees, Addis Ababa, Ethiopia: a cross-sectional study

Dyslipidemia and associated factors among hypertensive patients in Ethiopia: a systematic review and meta-analysis

INTRODUCTION

Dyslipidemia and other CVD risk factors in cardiac patients can lead to accelerated atherosclerosis, morbidity, and significant mortality. Identifying the potential contributory factors of dyslipidemia in hypertensive patients is crucial in order to manage the disease condition and reduce further complications. Although dyslipidemia has been studied in many countries, evidence of pooled prevalence and its risk factors in Ethiopia remains scarce. Thus, this meta-analysis aimed to estimate the pooled prevalence of dyslipidemia (high TG, low HDL-C, high LDL-C, and high TC) and associated factors among adults with hypertension in Ethiopia.

METHODS

The reporting system adhered to the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Articles were searched using electronic databases such as PubMed, Cochrane Library, Science Direct, African Journals Online, and Google Scholar from April 1 to April 21, 2024 to find relevant studies. We utilized Endnote X7 and STATA 11 for bibliographical management and statistical analysis, respectively. The heterogeneity of the included studies was analyzed using forest plots, Cochran's Q statistics, I² test, and P-values.

RESULTS

The electronic searches yielded 10,629 articles. Based on the quality assessment, all the included studies had high quality. The overall pooled prevalence of dyslipidemia among hypertensive patients in Ethiopia was 37.12% (95% CI: 31.79-42.44%; I²=98.4%). The pooled point estimates for high TC were (33.39%, 95% CI: 23.92-42.85; I²=97.9%), TG (38.89%, 95% CI: 32.90-44.88; I²=93.6%), high LDL-c (33.98%, 95% CI: 21.46-46.49; I²=98.4%), and low HDL-c (42.23%, 95% CI: 28.76-55.71; I²=98.9%). Based on this meta-analysis, dyslipidemia was associated with age ≥ 40 years and sedentary lifestyle.

CONCLUSION

This study suggests that dyslipidemia was high among the study participants, which underlines urgent need for early detection and public health interventions through the integrated involvement of public, governmental, and non-governmental organizations. Dyslipidemia was associated with, age ≥ 40 years, and sedentary lifestyle. This alarms the need for lipid profile assessment for patients periodically, with treatment follow-up to monitor any rising patterns and cardiovascular related risks.

Dyslipidemia in Adults with Type 2 Diabetes in a Rural Community in Ganadougou, Mali: A Cross-Sectional Study

Dyslipidemia is a disorder where abnormally lipid concentrations circulate in the bloodstream. The disorder is common in type 2 diabetics (T2D) and is linked with T2D comorbidities, particularly cardiovascular disease. Dyslipidemia in T2D is typically characterized by elevated plasma triglyceride and low high-density lipoprotein cholesterol (HDL-C) levels. There is a significant gap in the literature regarding dyslipidemia in rural parts of Africa, where lipid profiles may not be captured through routine surveillance. This study aimed to characterize the prevalence and demo-graphic profile of dyslipidemia in T2D in the rural community of Ganadougou, Mali. We performed a cross-sectional study of 104 subjects with T2D in Ganadougou between November 2021 and March 2022. Demographic and lipid profiles were collected through cross-sectional surveys and serological analyses. The overall prevalence of dyslipidemia in T2D patients was 87.5% (91/104), which did not differ by sex (P = .368). High low-density lipoprotein cholesterol (LDL-C) was the most common lipid abnormality (78.9%, [82/104]). Dyslipidemia was associated with age and hypertension status (P = .013 and.036, respectively). High total and high LDL-C parameters were significantly associated with hypertension (P = .029 and .006, respectively). In low-resource settings such as rural Mali, there is a critical need to improve infrastructure for routine dyslipidemia screening to guide its prevention and intervention approaches. The high rates of dyslipidemia observed in Gandadougou, consistent with concomitant increases in cardiovascular diseases in Africa suggest that lipid profile assessments should be incorporated into routine medical care for T2D patients in African rural settings.

Comparison of seven anthropometric indexes to predict hypertension plus hyperuricemia among U.S. adults

Purpose

This study aims to compare the association of hypertension plus hyperuricemia (HTN-HUA) with seven anthropometric indexes. These include the atherogenic index of plasma (AIP), lipid accumulation product (LAP), visceral adiposity index (VAI), triglyceride-glucose index (TyG), body roundness index (BRI), a body shape index (ABSI), and the cardiometabolic index (CMI).

Methods

Data was procured from the National Health and Nutrition Examination Survey (NHANES), which recruited a representative population aged 18 years and above to calculate these seven indexes. Logistic regression analysis was employed to delineate their correlation and to compute the odds ratios (OR). Concurrently, receiver operating characteristic (ROC) curves were utilized to evaluate the predictive power of the seven indexes.

Results

A total of 23,478 subjects were included in the study. Among these, 6,537 (27.84%) were patients with HUA alone, 2,015 (8.58%) had HTN alone, and 2,836 (12.08%) had HTN-HUA. The multivariate logistic regression analysis showed that the AIP, LAP, VAI, TyG, BRI, ABSI, and CMI were all significantly associated with concurrent HTN-HUA. The OR for the highest quartile of the seven indexes for HTN-HUA were as follows: AIP was 4.45 (95% CI 3.82-5.18), LAP was 9.52 (95% CI 7.82-11.59), VAI was 4.53 (95% CI 38.9-5.28), TyG was 4.91 (95% CI 4.15-5.80), BRI was 9.08 (95% CI 7.45-11.07), ABSI was 1.71 (95% CI 1.45 -2.02), and CMI was 6.57 (95% CI 5.56-7.76). Notably, LAP and BRI demonstrated significant discriminatory abilities for HTN-HUA, with area under the curve (AUC) values of 0.72 (95% CI 0.71 - 0.73) and 0.73 (95% CI 0.72 - 0.74) respectively.

Conclusion

The AIP, LAP, VAI, TyG, BRI, ABSI, and CMI all show significant correlation with HTN-HUA. Notably, both LAP and BRI demonstrate the capability to differentiate cases of HTN-HUA. Among these, BRI is underscored for its effective, non-invasive nature in predicting HTN-HUA, making it a superior choice for early detection and management strategies.

Epidemiology and Prevalence of Dyslipidemia Among Adult Population of Tehran: The Tehran Cohort Study

BACKGROUND

Dyslipidemia is among the leading risk factors for cardiovascular diseases (CVDs), with an increasing global burden, especially in developing countries. We investigated the prevalence of dyslipidemia and abnormal lipid profiles in Tehran.

METHODS

We used data from 8072 individuals aged≥35 from the Tehran Cohort Study (TeCS) recruitment phase. Fasting serum total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), and triglyceride were measured. Dyslipidemia was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria, and high LDL/HDL was defined as a ratio>2.5. The age-sex standardized prevalence rates were calculated based on the 2016 national census. Furthermore, the geographical distribution of dyslipidemia and lipid abnormalities was investigated across Tehran's zip code districts.

RESULTS

The age-sex standardized prevalence was 82.7% (95% CI: 80.1%, 85.0%) for dyslipidemia, 36.9% (95% CI: 33.8%, 40.1%) for hypertriglyceridemia, 22.5% (95% CI: 19.9%, 25.4%) for hypercholesterolemia, 29.0% (95% CI: 26.1%, 32.1%) for high LDL-C, 55.9% (95% CI: 52.6%, 59.2%) for low HDL-C, and 54.1% (95% CI: 50.9%, 57.3%) for high LDL/HDL ratio in the Tehran adult population. The prevalence of dyslipidemia, low HDL-C, and high LDL/HDL ratio was higher in the northern regions, hypercholesterolemia was higher in the southern half, and high LDL-C was more prevalent in the middle-northern and southern areas of Tehran.

CONCLUSION

We found a high prevalence of dyslipidemia, mainly high LDL/HDL in the Tehran adult population. This dyslipidemia profiling provides important information for public health policy to improve preventive interventions and reduce dyslipidemiarelated morbidity and mortality in the future.

Alcohol spiked with zolpidem and midazolam potentiates inflammation, oxidative stress and organ damage in a mouse model

PURPOSE

Crime-related spiking of alcoholic drinks with prescription drugs is quite common and has been happening for centuries. This study, therefore, evaluated the effects of oral administration of alcohol spiked with the zolpidem and midazolam potent sedatives on inflammation, oxidative stress and various organ damage in male Swiss albino mice.

METHODS

Mice were randomly assigned into six treatment groups; the first group constituted the normal control, the second group received 50 mg/kg body weight of zolpidem only, the third group received 50 mg/kg body weight zolpidem dissolved in 5 g/kg alcohol, the fourth group received 50 mg/kg midazolam only, the fifth group received midazolam (50 mg/kg) dissolved in 5 g/kg alcohol and the sixth group received 5 g/kg alcohol.

RESULTS

Alcohol-induced significant reduction in neurological function and altered blood hematological indicators. Such neurological impairment and negative effects on blood were exacerbated in mice administered with spiked alcohol. Additionally, midazolam and zolpidem enhanced alcohol-driven elevation of liver function markers; the serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) gamma glutamyltransferase (GGT), total bilirubin and alkaline phosphatase. Exposure to alcohol and/or spiked alcohol led to significant augmentation of nitric oxide and malonaldehyde, with concomitant depletion of liver glutathione (GSH) levels. Similarly, serum levels of pro-inflammatory cytokines tumor necrosis factor alpha and interferon-gamma were increased by co-exposure with midazolam or zolpidem. Alcohol-induced hepatotoxicity and nephrotoxicity were amplified by exposure to alcohol spiked with midazolam/zolpidem.

CONCLUSION

Exposure to alcohol spiked with midazolam or zolpidem appears to exacerbate neurological deficits, inflammation, oxidative stress, and organ damage.
