Background With the introduction of effective antiretroviral therapy (ART), people living with HIV (PLWH) are surviving longer and are at risk for developing metabolic abnormalities that contribute to cardiovascular disease (CVD). In Sub-Saharan Africa (SSA), there is a paucity of epidemiological data on lipid profiles among young adults receiving ART. This study aimed to estimate the prevalence of low high-density lipoprotein cholesterol (HDL-c), a cardioprotective lipid class, and whether it differed by age among adults on ART in Livingstone, Zambia. Methods From April to December 2019, we conducted a cross-sectional study of 597 PLWH [n = 58 aged 18–24 years (young adults); n = 539 aged ≥25 years (adults)] on ART for ≥6 months. Data collected included demographic and lifestyle information, anthropometrics, viral load (VL), CD4 count, blood pressure, lipid profiles and fasting/random blood glucose. Clinical measures were defined as: low HDL-c [<1.0 mmol/L for men, <1.3 for women], increased waist circumference (WC) [≥94 cm for men, ≥80 cm for women], high triglycerides (TG) [≥1.7 mmol/l], and virological failure (VF) [VL ≥1000 copies/μl]. We used logistic regression to examine the association between age and low HDL-c after adjusting for multiple variables. Results Among the young adults, 60% (35/58) were women, median (25th, 75th percentile) age 21 years (18, 23), and median time on ART 116 months (60, 144). Among adults, 63% (342/539) were women, median age 46 years (40, 53) and median time on ART 108 months (60, 144). Young adults had a lower CD4 count compared to adults (median, 492 vs. 568 cells/μL, p = 0.010) and higher prevalence of VF (29% vs. 17%, p = 0.016). In young adults, prevalence of low HDL-c was significantly higher than in adults (63 vs. 38%, p<0.001). A high proportion of young adults (75%) and adults (58%) with low HDL-c were on dolutegravir (DTG)-based ART regimens. After adjusting for sex, duration on ART, WC, body mass index, ART regimen, VF, CD4 count, low density lipoprotein cholesterol, blood pressure and smoking, young adults were significantly more likely than adults to have low HDL-c (odds ratio 2.93; 95% confidence interval 1.46–5.86). Conclusion Low HDL-c is highly prevalent among young adult with HIV in SSA independent of other risk factors for metabolic derangements. Lipid abnormalities among young PLWH may contribute to the early development of cardiovascular diseases in this population. This highlights the need to consider low HDL-c in the quest to reduce CVD risk among young adults on ART in SSA.

OBJECTIVE: To present information on the function, structure, and importance of high-density lipoprotein cholesterol (HDL-C) and to evaluate the current literature regarding the controversy of managing patients with an “isolated” low HDL-C concentration. DATA SOURCE: A MEDLINE search was performed (1966–June 1996) to identify English-language clinical and review articles pertaining to HDL-C. Some articles were identified through the bibliography of selected articles. STUDY SELECTION: All articles were considered for possible inclusion in the review. Pertinent information, as judged by the authors, was selected for discussion. DATA EXTRACTION: Important historical lipid studies, recent review articles, and clinical trials involving therapy for HDL-C were evaluated. DATA SYNTHESIS: The structure, function, and measurement of HDL-C and the state of an isolated low HDL-C are discussed for background. Lifestyle modification measures to increase HDL-C, medications to avoid, estrogen replacement, and lipid-altering agents used to raise an isolated low HDL-C are presented. CONCLUSIONS: An isolated low HDL-C concentration poses a risk for coronary heart disease. The management of this state is controversial. The first step in management is in agreement with experts and includes lifestyle modification (e.g., weight reduction, diet, smoking cessation, aerobic exercise). Estrogen replacement therapy and discontinuance of drugs that secondarily lower HDL-C are additional treatment options. The use of lipid-altering agents has been used in some patients. Nicotinic acid appears to be an effective agent for an isolated low HDL-C. A large clinical trial evaluating the effect of treating an isolated low HDL-C for primary and secondary prevention of coronary events is needed.

Background: This study aimed to examine the association between physical activity (PA) and a total cardio metabolic risk (CMR) score in children aged 3–12 years. Secondary objectives were to examine the association between PA and individual CMR factors. Methods: A longitudinal study with repeated measures was conducted with participants from a large primary care practice-based research network in Toronto, Canada. Mixed effects models were used to examine the relationship between parent-reported physical activity and outcome variables (total CMR score, triglycerides, glucose, high-density lipoprotein cholesterol, systolic blood pressure, waist circumference, weight-to-height ratio, and non-high-density lipoprotein cholesterol). Results: Data from 1885 children (6.06 y, 54.4% male) with multiple visits (n = 2670) were included in the analyses. For every unit increase of 60 minutes of PA, there was no evidence of an association with total CMR score (adjusted: −0.02 [−0.014 to 0.004], P = .11]. For the individual CMR components, there was evidence of a weak association between PA and systolic blood pressure (−0.01 [−0.03 to −0.01], P < .001) and waist-to-height ratio (−0.81 [−1.62 to −0.003], P < .001). Conclusion: Parent-reported PA among children aged 3–12 years was not statistically associated with total CMR, but was weakly associated with systolic blood pressure and waist-to-height ratio.

Abstract BackgroundLow levels of high-density lipoprotein-cholesterol (HDL-C) and diabetes are common in patients undergoing peritoneal dialysis (PD). The aim of this study was to investigate the association between diabetes coexisting with a low level of HDL-C and the first episode of peritoneal dialysis-related peritonitis (PDRP) in patients with PD.MethodsWe retrospectively investigated patients with PD from January 1, 2003, to May 31, 2020 in four PD centers. Patients with PD were divided into four groups: no comorbidity, low HDL-C only, diabetes only, and diabetes plus low HDL-C. The clinical and laboratory baseline data of the four groups were collected and compared. The association between diabetes coexisting with low HDL-C levels and the first episode of PDRP was analysed by multivariate Cox regression analysis. ResultsA total of 1013 patients with PD were recorded in our study. The mean age was 49.94±14.32 years, and 597 (58.99%) were males. A total of 301 (29.7%) patients had their first episodes of PDRP, and low HDL-C levels existed with diabetes in 72 patients with PD. After adjusting for confounding factors, a low level of HDL-C coexisting with diabetes was significantly associated with the first episode of PDRP in our study (hazard ratio: 1.93, 95% CI: 1.03-3.61, p<0.05). The associations between HDL-C, diabetes and PDRP were consistent in the following subgroups: sex, age, pre-existing CVD (all P interaction > 0.05).ConclusionsLow levels of HDL-C alone or diabetes alone were not independent risk factors for PDRP. Patients with both diabetes and low HDL-C levels were at high risk for PDRP.

AimsLow IGF1 levels have been associated with an increased cardiovascular risk. It is unknown however whether IGF1 mediates the atherosclerotic process by modulating high-density lipoprotein cholesterol (HDL-C) independently from confounders. To address this issue, we evaluated the association between IGF1 levels and HDL-C in nondiabetic subjects.MethodsA cross-sectional analysis was used in the context of the CAtanzaro MEtabolic RIsk factors Study. One thousand and four participants (aged 20–69 years), for whom HDL-C and IGF1 measurements were available, were eligible for the study.ResultsAfter adjusting for gender and age, IGF1 levels were positively correlated with HDL-C, and negatively correlated with body mass index (BMI), waist circumference, blood pressure (BP), triglyceride, fasting insulin, and homeostasis model assessment (HOMA). In a logistic regression model adjusted for age and gender, IGF1 in the lowest tertile (<125 ng/ml) was associated with an increased risk of having low HDL-C (odds ratio (OR) 2.14, 95% confidence interval (CI) 1.4–3.0; P=4×10−5) compared with the highest tertile (>186 ng/ml). When BMI, waist circumference, total cholesterol, triglyceride, and HOMA index were added to the model, IGF1 remained significantly associated with increased risk of low HDL-C (OR 1.52, 95% CI 1.01–2.31; P=0.04). A stepwise multivariate regression analysis in a model including age, gender, BMI, total cholesterol, triglycerides, IGF1, HOMA, and BP showed that the variables significantly associated with HDL-C were gender (P<0.0001), triglycerides (P<0.0001), total cholesterol (P<0.0001), BMI (P<0.0001), IGF1 levels (P<0.0001), and HOMA (P=0.001), accounting for 32.6% of its variation.ConclusionsThese data provide evidence that IGF1 may be an independent modulator for HDL-C in nondiabetic individuals.

Objective. To determine whether lipid disorders can be predicted in parents after such disorders are identified initially in their children. Although this relation has been well determined for children with high cholesterol or low-density lipoprotein cholesterol (LDL-C), it has not been as well described for disorders involving triglycerides (TG) or high-density lipoprotein cholesterol (HDL-C), or their interaction with LDL-C. Methods. Serum lipid values were obtained from 232 families in the comparison population of a large genetics study. Subjects were classified into four groups based on their lipid status: 1) isolated LDL-C disorder, defined by a high LDL-C level and normal TG and HDL-C levels; 2) isolated TG/HDL-C disorder, defined by either high TG, low HDL-C, or both, and normal LDL-C; 3) combined disorder, defined by high LDL-C in addition to either high TG, low HDL-C, or both; and 4) normal, defined by the absence of any of the above disorders. The frequencies of these disorders were noted in both parents and children, and logistic regression analyses were conducted to determine whether the presence of these disorders in at least one child in the family could predict similar disorders in the parents. Results. Children with isolated LDL-C or TG/HDL-C disorder were more likely to have parents with the same disorder as themselves (P = .002 and P = .04, respectively). Children with the combined disorder were more likely to have parents with any lipid disorder (P = .009), but especially isolated LDL-C (P = .002) and isolated TG/HDL-C (P = .05). Conclusion. A classification scheme defining disorders of TG and HDL-C, LDL-C, or a combination can be useful for predicting lipid disorders in parents after such disorders are identified initially in their children.
