CKD Prevalence in HIV Patients on TDF: A Global Perspective

Key Insights

CKD Prevalence: The global pooled prevalence of CKD among PLWHIV on TDF regimens is 7%. This indicates a significant health concern linked to CKD prevalence HIV TDF.

Risk Factors: Low CD4 count (<200 copies/ml) and female gender are significant risk factors for CKD in this population.

Regional Variations: CKD prevalence varies significantly across regions. Higher rates are observed in Sub-Saharan Africa.

TDF Nephrotoxicity: TDF causes renal toxicity, likely by inhibiting mitochondrial DNA polymerase gamma, though the exact mechanism remains unclear.

Background Context

Healthcare providers widely use Tenofovir Disoproxil Fumarate (TDF) as an antiretroviral drug for HIV treatment. It is known for its efficacy and safety profile. However, it has been linked to renal toxicity and CKD, especially in populations with pre-existing renal conditions or other risk factors. The World Health Organization (WHO) and other health authorities recommend monitoring renal function in patients on TDF-based regimens. TDF use is common globally, but its nephrotoxic effects require careful management and monitoring. This is particularly important in resource-limited settings where baseline renal function assessments may not be routine.

Implications

The purpose of this content is to highlight the significant implications of this study’s findings for health economics and outcomes research:

Healthcare Policy: The high prevalence of CKD among PLWHIV on TDF regimens underscores the need for healthcare policymakers to develop strategies for early CKD detection and management.

Resource Allocation: In low-income countries, prioritising renal function monitoring for those on TDF could help mitigate CKD risk.

Alternative Treatments: The study supports considering alternative antiretroviral drugs like Tenofovir Alafenamide (TAF). TAF has better renal safety profiles compared to TDF.

Economic Impact: Long-term CKD management can be costly. Preventing its onset through careful drug selection and monitoring could reduce healthcare expenditures. For more details, refer to the original study.

By focusing on the CKD prevalence HIV TDF, this review emphasises the importance of monitoring and proactive measures in the care of PLWHIV.

June 30, 2025 Rene Pretorius

🚀 Are prior authorizations stalling care delivery in the U.S. healthcare system?

The HHS has launched an ambitious collaboration with major insurers to reform prior authorization processes across Medicare Advantage, Medicaid, and commercial plans. With a goal to standardize submissions by 2027 and significantly reduce requirements by 2026, this initiative promises to accelerate care decisions and enhance transparency.

Dive into the details of these pivotal reforms and discover their potential to streamline healthcare and improve patient outcomes.

Impending Net Drug Price Transparency Regulation in the U.S.

June 27, 2025June 27, 2025 Rene Pretorius

💡 Are you ready for a potential game-changer in drug pricing transparency?

CMS Administrator Mehmet Oz has hinted at a new rule aimed at enforcing stricter disclosures for drug prices, requiring healthcare companies to reveal actual transaction costs. This could reshape how price transparency is managed across the industry and challenge pharmacy benefit managers to rethink rebate practices.

Curious about how this will impact healthcare economics and what it means for drug affordability? Dive into the article for all the insights!
