AI Article Synopsis
- HIV-associated lipodystrophy (HIVLD) is a condition related to abnormal lipid metabolism in HIV-infected individuals, influenced by specific gene polymorphisms affecting lipoprotein transport.
- A study of 187 patients identified the 34A allele and -493T allele as having a non-significant association with reduced severity of HIVLD and lower dyslipidemia risk, respectively.
- Findings suggest that individuals without HIVLD carrying the 34GA genotype have impaired triglyceride levels, indicating a potential increased risk for developing dyslipidemia.
Article Abstract
HIV-associated lipodystrophy (HIVLD) is a metabolic condition with an irregularity in the production of lipoprotein particles, and its occurrence varies among HIV-infected patients. and genes have a role in the transport of lipoproteins. The polymorphisms of -493G/T and 34G/A affect its expression and influence the secretion and transportation of lipoproteins. Hence, we investigated the 493G/T and 34G/A polymorphisms in 187 HIV-infected patients (64 with HIVLD and 123 without HIVLD) along with 139 healthy controls using polymerase chain reaction (PCR)-restriction fragment length polymorphism and expression analysis using real-time PCR. 34A allele showed an insignificantly reduced risk of LDHIV severity [ = 0.07, odds ratio (OR) = 0.55]. -493T allele exhibited a non-significantly reduced risk for the development of dyslipidemia ( = 0.08, OR = 0.71). In patients with HIVLD 34GA genotype was linked with impaired low-density lipoprotein levels and showed a reduced risk for LDHIV severity ( = 0.04, OR = 0.17). In patients without HIVLD, 34GA genotype was associated with impaired triglyceride levels with marginal significance and showed an increased risk for the development of dyslipidemia ( = 0.07, OR = 2.76). The expression level of gene was 1.22-fold decreased in patients without HIVLD compared with that in patients with HIVLD. gene was upregulated 2.16-fold in patients with HIVLD than in patients without HIVLD. In conclusion, -493C/T polymorphism influences the expression level of in patients without HIVLD. Individuals without HIVLD having 34GA genotype with impaired triglyceride levels may facilitate dyslipidemia risk.

Article Synopsis
- - The study examined the impact of ApoE gene polymorphisms on HIV-related lipodystrophy (HIVLD) and metabolic abnormalities in 200 HIV-infected patients, revealing that certain genotypes might influence the risk of developing these conditions.
- - Results indicated that ApoE alleles 2 and specific genotypes, like 4/4, were connected to a decreased risk of HIV-1 infection and a lower likelihood of severe HIVLD, whereas allele 2 was linked to increased risk of both HIV acquisition and HIVLD severity.
- - Additionally, the study found correlations between specific ApoE genotypes and impaired cholesterol and glucose levels in patients without HIVLD, highlighting the intricate relationship between genetics and metabolic health in the context

Article Synopsis
- Lipodystrophy leads to the progressive loss of fat tissue and various metabolic issues, necessitating a better understanding of its associated health risks in the absence of treatment.
- A study examining data from 2018-2019 revealed that individuals with non-HIV-associated lipodystrophy had significantly higher risks for several conditions like hyperlipidemia, hypertension, and diabetes compared to the general population.
- Furthermore, people with HIV-associated lipodystrophy also faced elevated risks for hypertension, hyperlipidemia, and diabetes when compared to non-HIV patients with lipodystrophy.

Article Synopsis
- Apolipoproteins and SCARB1 proteins play a role in HIV-associated lipodystrophy (HIVLD), with specific genetic polymorphisms influencing risk factors for cardiovascular diseases.
- The study examined 3238C/G, 12669G/A, and 1050C/T polymorphisms in 187 HIV patients and 139 healthy controls, finding specific genotypes linked to severe HIVLD and altered lipid levels.
- Overall, while the polymorphisms did not directly modify HIVLD risk, they indicated increased susceptibility when combined with unfavorable lipid and glucose levels.

Article Synopsis
- Protease inhibitors (PIs) have been linked to lipodystrophy, a condition marked by loss of body fat in people living with HIV, with variations in this condition influenced by genetic factors and environmental elements.
- A study sequenced lipid metabolism-related genes in 48 patients, revealing novel genetic variants in the ABCB6 and GRN genes that may be associated with the presence or absence of HIV-related lipodystrophy.
- The findings indicate that specific genetic mutations could affect protein production, potentially worsening lipodystrophy symptoms, while other mutations may help understand the absence of this condition in certain individuals.
