Naringin: A Natural Shield Against HIV Drug Side Effects?
"Can this citrus flavonoid combat dyslipidemia and oxidative stress induced by HIV protease inhibitors?"
Combination antiretroviral therapy (cART) has transformed HIV-1 infection management, significantly decreasing mortality and morbidity. This therapeutic approach uses Nucleotide Reverse Transcriptase Inhibitors (NRTIs), Non-Nucleosides Reverse Transcriptase Inhibitors (NNRTIs), Protease Inhibitors (PIs), Integrase Inhibitors, and Entry/Fusion Inhibitors, offering various options tailored to individual patient needs. However, while cART has dramatically improved the quality of life for individuals with HIV, the long-term use of these medications is associated with metabolic complications that can undermine their health.
A significant concern is the development of metabolic complications, particularly with HIV PI-based regimens, leading to dyslipidemia, lipodystrophy, and insulin resistance. These conditions elevate the risk of diabetes and cardiovascular diseases, posing a challenge to long-term health management. Dyslipidemia, characterized by increased LDL-cholesterol (LDL-c) and triglycerides (TG) and decreased HDL-cholesterol (HDL-c), affects up to 50% of patients undergoing PI treatment, exacerbated by viral pathogenesis.
Given these challenges, researchers are exploring interventions to mitigate PI-associated metabolic complications. While strategies like switching antiretroviral agents, surgical options, and various medications have had limited success, natural compounds like naringin are gaining attention. Naringin, a flavonoid from Citrus paradise, exhibits anti-atherogenic, anti-dyslipidemic, and antioxidant properties. This article delves into a study investigating naringin’s potential to counteract dyslipidemia and oxidative stress induced by HIV PIs.
Naringin's Protective Mechanisms: How Does It Work?
A study published in the "Journal of Functional Foods" (2019) investigated the protective effects of naringin against dyslipidemia and oxidative stress induced by HIV-1 protease inhibitors (PIs). Conducted in vivo using male Wistar rats, the research involved daily oral treatments of atazanavir (ATV) or saquinavir (SQV), with and without naringin, over 56 days. The results highlighted significant improvements in several key health markers.
- Body Weight: Naringin helped counteract the weight loss typically associated with ATV or SQV treatments.
- Lipid Profile: It improved dyslipidemia by reducing total cholesterol, triglycerides, LDL-cholesterol, and VLDL-cholesterol concentrations while increasing HDL-cholesterol levels.
- Atherogenic Index: Naringin reduced the calculated atherogenic index, indicating a lower risk of cardiovascular disease.
- Oxidative Stress: It decreased lipid peroxidation and carbonyl protein concentrations in plasma, liver, and pancreas tissues, enhancing antioxidant activities in the liver and pancreas.
Future Implications: Integrating Naringin into HIV Treatment Strategies
The study's findings open new avenues for adjunctive therapies that could improve the health outcomes for individuals undergoing HIV treatment. Naringin's ability to counteract dyslipidemia and oxidative stress suggests it may be a valuable addition to existing treatment strategies. Further research is needed to determine the optimal dosage and delivery methods of naringin, as well as its long-term effects and potential interactions with other medications. If these findings translate into clinical practice, naringin could offer a natural, accessible way to mitigate the metabolic complications associated with HIV protease inhibitors, ultimately enhancing the quality of life for those living with HIV.
