Meta-Analysis
INTRODUCTION
Dyslipidemia is a common public health problem in people living with human immunodeficiency virus (HIV) who are receiving antiretroviral therapy and increases the risk of cardiovascular disease. Although evidence indicates that the prevalence of dyslipidemia is high, estimated pooled data are not well documented. Therefore, we aimed to estimate the pooled prevalence of dyslipidemia in adult people living with HIV receiving antiretroviral therapy in Ethiopia.
METHOD
We conducted a systematic review and meta-analysis of the literature. The following databases and grey literature were searched: PubMed, WorldCat, ScienceDirect, DOAG, African Journals Online, Google Scholar, and African Index Medicine. We included all comparative epidemiological studies that reported the prevalence of high concentration of total cholesterol, triglycerides, and low density lipoprotein, and low concentration of high density lipoprotein cholesterol that were published between January 2003 and July 2023. The random effects model was used to pool the outcome of interest. Additionally, subgrouping, sensitivity analyses, and funnel plots were performed. R software Version 4.2.1 was used for statistical analysis.
RESULT
Seventeen studies with a total of 3929 participants were included in the meta-analysis. The pooled prevalence of dyslipidemia, high total cholesterol, high triglyceride, elevated level of low density lipoprotein and low level of high density lipoprotein cholesterol were 69.32% (95% CI: 63.33, 74.72), 39.78% (95%CI: 32.12, 47.96), 40.32% (95%CI: 34.56, 46.36), 28.58% (95%CI: 21.81, 36.46), and 36.17% (95%CI: 28.82, 44.24), respectively. Age and body mass index were associated with high total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels.
CONCLUSION
The authors concluded that the prevalence of dyslipidemia in Ethiopia is high in people living with HIV receiving antiretroviral therapy. Early detection of dyslipidemia and its integration into treatment are essential for preventing cardiovascular disease.

Evaluating the Effectiveness and Safety of Evinacumab in Treating Hypercholesterolemia and Hypertriglyceridemia: A Systematic Review and Meta-analysis of Randomized Controlled Trials.
BACKGROUND
Cardiovascular disease remains a significant global health concern, with high low-density lipoprotein cholesterol (LDL-C) levels contributing to an increased risk. Familial hypercholesterolemia (FH) further complicates its management, necessitating additional lipid-lowering therapies. Evinacumab, an angiopoietin-like protein 3 monoclonal antibody, has emerged as a potential treatment, particularly for patients with FH, by effectively reducing LDL-C and triglyceride levels. This meta-analysis aimed to evaluate the efficacy and safety of evinacumab across diverse patient populations.
METHODS
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, relevant randomized controlled trials (RCTs) were systematically retrieved from multiple databases until November 24, 2023. The inclusion criteria were studies comparing evinacumab (at doses of 5 and 15 mg) to placebo, with outcomes focusing on lipid levels and adverse events. Standardized protocols were employed for data extraction and quality assessment, and statistical analysis was conducted using RevMan software.
RESULTS
Four RCTs, involving 270 patients, were included in the analysis. The analysis revealed significant reductions in lipid markers, particularly with the 15-mg dose of evinacumab, including triacylglycerols (standard mean difference [SMD] = -6.09, 95% confidence interval [CI] - 14.53 to 2.36, P = 0.16), total cholesterol (SMD = - 6.20, 95% CI - 11.53 to - 0.88, P = 0.02), high-density lipoprotein cholesterol (SMD = - 0.79, 95% CI - 1.27 to - 0.31, P = 0.001), LDL-C (SMD = - 4.58, 95% CI - 9.13 to - 0.03, P = 0.05), apolipoprotein (Apo) B (SMD = - 4.01, 95% CI - 7.53 to - 0.46, P = 0.03), and Apo C3 (SMD = - 7.67, 95% CI - 12.94 to - 2.41, P = 0.004). Adverse event analysis revealed no significant association, indicating good tolerability.
CONCLUSION
High-dose evinacumab (15 mg) consistently demonstrated efficacy in reducing cholesterol and other lipid markers, with favorable tolerability. Further research is warranted to comprehensively assess its safety and clinical effectiveness, emphasizing the need for additional data to support its use in managing cardiovascular disease.

Meta-Analysis Review
Plantago is rich in soluble fiber, known for its beneficial health effects. Given this, we hypothesized that Plantago consumption might positively influence blood lipid in adults. Researchers have conducted numerous randomized controlled trials (RCTs), revealing the impacts of Plantago consumption on various blood lipid parameters. However, findings regarding specific blood lipid parameters have shown variability. This study aimed to comprehensively assess the effect of Plantago consumption on blood lipid parameters. Eligible studies evaluating the effects of Plantago consumption on blood lipid were searched in 5 electronic databases published up to August 2023. Analysis used a random effects model to determine weighted mean difference and 95% confidence intervals. In total, 29 RCTs including 2769 participants were included. Compared with the control group, Plantago consumption significantly reduced total cholesterol (TC) by 0.28 mmol/L and low-density lipoprotein cholesterol (LDL-C) by 0.35 mmol/L, correlating to an estimated 7% decrease in cardiovascular event risk. Conversely, no substantial effects were observed on high-density lipoprotein cholesterol or triglycerides. Subgroup analyses of 29 RCTs revealed that TC concentrations were significantly lowered in studies that included male participants, those who were healthy, or had lipid disorders. Additionally, TC and LDL-C were significantly lower in participants consuming Plantago husk or psyllium, and soluble fiber intake was specifically effective in lowering TC, LDL-C, and triglycerides. In conclusion, Plantago consumption can significantly lower TC and LDL-C concentrations. The findings will provide crucial insights into the potential of Plantago in dietary strategies for blood lipid management.

Meta-Analysis
AIM
As periodontitis and dyslipidemia are diseases that occur with high incidence, the relationship between them has attracted much attention. Previous studies on these diseases have tended to focus on lipid parameters and periodontitis, we aimed to investigate the relationship between dyslipidemia and periodontitis.
MATERIALS AND METHODS
A comprehensive search to identify the studies investigating the relationship between dyslipidemia and periodontitis was performed on PubMed, Web of Science and Cochrane Library before the date of August, 2023. Studies were considered eligible if they contained data on abnormal blood lipid parameters and periodontitis. Studies that reported mean differences and 95% confidence intervals or odds ratios were used.
RESULTS
A total of 73 publications were included in the meta-analysis. Hyper total cholesterol (TC), triglycerides (TGs), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) and lower high-density lipoprotein (HDL) levels are risk factors for periodontitis. Periodontal disease is a risk factor for high TG and low HDL levels. Three months after periodontal treatment, the levels of TC, TG and HDL were significantly improved, and statin treatment only improved gingival index (GI) levels compared to that of the dietary control.
CONCLUSIONS
The findings reported here suggest that the mutual promotion of periodontitis and dyslipidemia can be confirmed. Non-surgical periodontal therapy may improve lipid abnormalities. It can't be demonstrated whether systematic application of statins have a better effect on the improvement in periodontal status in patients with dyslipidemia compared to that of the control.

Review
BACKGROUND
Overall, there is conflicting evidence regarding the beneficial effects of optimal lifestyle modification, particularly weight loss interventions, with nonalcoholic fatty liver disease (non-alcoholic fatty liver disease (NAFLD)). Therefore, this study investigated the effects of weight loss interventions on laboratory and clinical parameters in children and adolescents with NAFLD.
METHODS
Original databases (PubMed/MEDLINE, Web of Science, SCOPUS, and Embase) were searched using standard keywords to identify all controlled trials investigating the effects of weight loss interventions among NAFLD children and adolescents. Pooled weighted mean difference and 95% confidence intervals were achieved by random-effects model analysis.
RESULTS
Eighteen eligible clinical trials were included in this systematic review and meta-analysis. The pooled findings showed that especially more intense weight loss interventions significantly reduced the glucose ( = 0.007), insulin ( = 0.002), homeostatic model assessment-insulin resistance (HOMA-IR) ( = 0.003), weight ( = 0.025), body mass index (BMI) ( = 0.003), BMI -score ( < 0.001), waist circumference (WC) ( = 0.013), triglyceride (TG) ( = 0.001), and aspartate transaminase (AST) ( = 0.027). However, no significant changes were found in total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine transaminase (ALT), and hepatic steatosis grades (all > 0.05) following weight loss interventions.
CONCLUSIONS
Weight loss interventions had significant effects on NAFLD-related parameters including glucose, insulin, HOMA-IR, weight, BMI, BMI z-score, WC, TG, and AST.

Meta-Analysis Review
BACKGROUND
People with serious mental illnesses (SMIs) such as schizophrenia and bipolar disorder die up to 30 years younger than individuals in the general population. Premature mortality among this population is often due to medical comorbidities, such as type 2 diabetes (T2D). Being a disease directly related to diet, adverse lifestyle choices, and side effects of psychotropic medication, an effective approach to T2D treatment and management could be non-pharmacological interventions. This systematic review and meta-analysis (1) summarise the current evidence base for non-pharmacological interventions (NPI) for diabetes management in people living with SMI and (2) evaluate the effect of these interventions on diverse health outcomes for people with SMI and comorbid diabetes.
METHODS
Six databases were searched to identify relevant studies: PubMed (MEDLINE), PsycINFO, Embase, Scopus, CINAHL, and Web of Science. Studies were included if they reported on non-pharmacological interventions targeted at the management of T2D in people living with SMI. To be eligible, studies had to further involve a control group or report multiple time points of data in the same study population. Whenever there were enough interventions reporting data on the same outcome, we also performed a meta-analysis.
RESULTS
Of 1867 records identified, 14 studies were included in the systematic review and 6 were also eligible for meta-analysis. The results showed that there was a reduction, although not significant, in glycated haemoglobin (HbA1c) in the NPI group compared with the control, with a mean difference of -0.14 (95% CI, -0.42, 0.14, = 0.33). Furthermore, NPI did not significantly reduce fasting blood glucose in these participants, with a mean difference of -17.70 (95% CI, -53.77, 18.37, = 0.34). However, the meta-analysis showed a significant reduction in psychiatric symptoms: BPRS score, -3.66 (95% CI, -6.8, -0.47, = 0.02) and MADRS score, -2.63 (95% CI, -5.24, -0.02, = 0.05). NPI also showed a significant reduction in the level of total cholesterol compared with the control, with a mean difference of -26.10 (95% CI, -46.54, -5.66, = 0.01), and in low-density lipoprotein (LDL) cholesterol compared with control, with a standardised mean difference of -0.47 (95% CI, -0.90, -0.04, = 0.03). NPI did not appear to have significant effect ( > 0.05) on body mass index (BMI), health-related quality of life (HRQL), triglycerides, and high-density lipoprotein cholesterol compared with control.
CONCLUSIONS
This systematic review and meta-analysis demonstrated that NPI significantly ( < 0.05) reduced psychiatric symptoms, levels of total cholesterol, and LDL cholesterol in people with type 2 diabetes and SMI. While non-pharmacological interventions also reduced HbA1c, triglyceride, and BMI levels and improved quality of life in these people, the effects were not significant ( > 0.05).

Review
It has been suggested that silymarin (SIL) supplementation has positive effects on cardiovascular health and reduces the risk of cardiometabolic syndrome (CMS). This systematic review and dose-response meta-analysis assessed the impacts of SIL administration on cardiovascular risk factors. A systematic search of multiple databases was performed to identify eligible controlled trials published up to January 2023. The analysis used a random-effects model and included 33 trials with 1943 participants. It was revealed that SIL supplementation led to a notable reduction in serum levels of fasting blood glucose (FBG) (weighted mean difference (WMD): -21.68 mg/dL, 95% CI: -31.37, -11.99; < 0.001), diastolic blood pressure (DBP) (WMD: -1.25 mmHg; 95% CI: -2.25, -0.26; = 0.013), total cholesterol (TC) (WMD: -13.97 mg/dL, 95% CI: -23.09, -4.85; = 0.003), triglycerides (TG) (WMD: -26.22 mg/dL, 95% CI: -40.32, -12.12; < 0.001), fasting insulin (WMD: -3.76 mU/mL, 95% CI: -4.80, -2.72; < 0.001), low-density lipoprotein (LDL) (WMD: -17.13 mg/dL, 95% CI: -25.63, -8.63; < 0.001), and hemoglobin A1C (HbA1c) (WMD: -0.85%, 95% CI: -1.27, -0.43; < 0.001) in the SIL-treated groups compared to their untreated counterparts. In addition, there were no substantial differences in body mass index (BMI), systolic blood pressure (SBP), C-reactive protein (CRP), body weight, and high-density lipoprotein (HDL) between the two groups. These outcomes suggest that SIL consumption reduces certain CMS risk factors and has favorable impacts on lipid and glycemic profiles with potential hypotensive effects. These findings should be supported by additional trials with larger sample sizes and longer durations.

AIMS
Homozygous familial hypercholesterolemia (HoFH) is a rare disorder characterized by markedly elevated circulating low-density lipoprotein cholesterol (LDL-C) from birth. This review aimed to critically evaluate treatments for HoFH with respect to their efficacy, safety, accessibility, overall context and position within the treatment pathway.
METHODS
A mixed-methods review was undertaken to systematically identify and characterize primary interventional studies on HoFH, with a focus on LDL-C reduction as the primary outcome. Interventions assessed were ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i), lomitapide, evinacumab, with or without LDL apheresis.
RESULTS
Twenty-six seminal studies reporting unique patient data were identified. Four studies were randomized controlled trials (RCTs) with the remainder being single-arm trials or observational registries. Data extracted were heterogeneous and not suitable for meta-analyses. Two RCTs, assessed at being low risk of bias, demonstrated PCSK9i were safe and moderately effective. An RCT demonstrated evinacumab was safe and effective in all HoFH subgroups. Lomitapide was reported to be efficacious in a single-arm trial, but issues with adverse events, tolerability, and adherence were identified. An RCT on ezetimibe showed it was moderately effective when combined with a statin. LDL apheresis was reported as effective, but its evidence base was at very high risk of bias. All interventions lowered LDL-C, but the magnitude of this, and certainty in the supporting evidence, varied.
CONCLUSION
In practice, multiple treatments are required to treat HoFH. The sequencing of these should be made on an individualized basis, with consideration made to the benefits of each intervention.

Meta-Analysis
Interleukin-6 (IL-6), a pivotal pro-inflammatory cytokine, is closely linked to vascular wall thickening and atherosclerotic lesion. Since serum IL-6 levels are largely determined by the genetic variant in IL-6, this study was conducted to investigate whether the IL-6 variant impacts cardiometabolic profile and the risk of premature coronary artery disease (PCAD). PubMed, Cochrane Library, Central, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and ClinicalTrials.gov were searched from May 13, 2022 to June 28, 2023. In total, 40 studies (26,543 individuals) were included for the analysis. The rs1800795 (a function variant in the IL-6 gene) C allele was linked to higher levels of low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), fasting plasma glucose (FPG), body mass index (BMI), and waist circumference (WC), and a lower levels of high-density lipoprotein cholesterol (HDL-C). However, no significant association was observed of rs1800795 with triglycerides (TG), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Interestingly, a significant association was detected between rs1800795 and PCAD. Subgroup analyses indicted that the impacts of rs1800795 on cardiometabolic risk factors were significant in Caucasians but stronger in obese patients. In contrast, the impact of rs1800795 on PCAD was significant in brown race population. In summary, rs1800795 had a slight but significant impact on cardiometabolic risk factors and PCAD. IL-6 inhibition with ziltivekimab or canakinumab may benefit high-risk populations (e.g. brown race population, Caucasians, obese patients, etc.) with rs1800795 to prevent PCAD.

Review
INTRODUCTION
People living with HIV (PLWH) receiving statin therapy have shown improved lipid profiles. However, they are not free from side effects, thereby requiring strict monitoring of the therapy. The meta-analysis aims to analyze the effect of statins in PLWH and critically appraise the effectiveness of statin therapy in PLWH.
METHODS
PubMed, Scopus, and Web of Science servers were used to conduct a systematic search in compliance with the PRISMA guidelines. The meta-analysis of pooled effect estimates is produced using Revman software.
RESULTS
A total of 12 RCTs with 8716 participants were included in the analysis. Analysis of the overall effect estimates found that statins resulted in a mean reduction of 41.15 mg/dl (MD = -41.15; 95% CI: -44.19, -38.11; < 0.00001), 34.99 mg/dl (MD = -34.99; 95% CI: -34.99; 95% CI: -41.16, -28.82; < 0.00001), and 7.36 mg/dl (MD = -7.36; 95% CI = -48.35, -33.62; < 0.00001) in total cholesterol, low-density lipoprotein, and triglyceride levels, respectively. It is revealed that statins are associated with a significant increase in the discontinuation rate of treatment compared to placebo treatment (RR: 1.90; 95% CI: 1.36-2.65; = 0.0002).
CONCLUSION
When considered collectively, statin therapy's advantages appear to exceed its occasional predictable side effects like liver or muscle toxicity.
