The Role of Rapid ART and LDH in HIV Management: A Game-Changer for Viral Suppression
The rapid initiation of antiretroviral therapy (ART) in people living with HIV (PLWH) is a critical strategy for improving clinical outcomes and controlling disease progression. Early ART initiation not only reduces viral load but also prevents immune system deterioration, considerably lowering morbidity and mortality from opportunistic infections and AIDS-defining illnesses. Furthermore, prompt ART initiation enhances viral suppression and retention in care, offering psychological benefits to patients. This approach aligns with the UNAIDS 95–95-95 targets, which aim to expedite viral suppression in a greater proportion of the HIV-positive population, contributing to epidemic control.
However, challenges persist. Not all antiretroviral drugs are suitable for rapid ART initiation, and disparities in medical resources and economic conditions often delay access to optimal treatments. Viral suppression is influenced by factors such as baseline viral load, adherence, ART regimens, treatment duration, and the emergence of drug-resistant strains.In this context, early identification of viral suppression in PLWH is crucial.Enter lactate dehydrogenase (LDH), an intracellular enzyme that serves as a promising biomarker for predicting viral suppression. LDH levels, which can deviate due to multi-organ injuries, infections, or glycolytic upregulation, have shown important predictive potential in various viral diseases. As an example, in chronic lymphocytic leukemia patients, higher LDH levels correlated with increased EBV-DNA copy numbers, linked to accelerated disease progression. Similarly,in pediatric Mycoplasma pneumoniae pneumonia patients,persistent Mycoplasma DNA positivity was associated with elevated LDH levels,suggesting a strong link between LDH and DNA clearance.
Studies have also highlighted LDH’s role in differentiating between primary and reinfection cases.For example,Nishijima et al found significantly higher LDH levels and viral loads in primary measles virus infections compared to reinfections. In COVID-19 patients, serum LDH levels correlated with Ct values, indicating a positive association with higher viral loads.
Despite its potential, limited data exists on LDH’s use as a biomarker for predicting viral suppression in PLWH. This gap is particularly concerning in resource-limited regions, were cost-effective, compliant, and timely diagnostic indicators are essential. LDH, as a routine clinical parameter, offers distinct advantages. Economically, it provides a cost-efficient approach to diagnosis and monitoring, enhancing medical resource utilization. For patients, LDH implementation simplifies treatment, improves adherence, and supports long-term management. Timely LDH detection facilitates swift disease status evaluation and treatment adjustments, making it a practical choice for resource-limited settings.
To address this, a retrospective cohort study was conducted to analyze the prognostic significance of serum LDH levels in achieving viral suppression among PLWH.

According to the UNAIDS report, 71% (60–83%) of PLWH worldwide achieved viral suppression in 2022. However, the study in question revealed a significantly higher viral suppression rate of 94.1% among its participants. While this figure surpasses the global average, it still falls short of the enterprising “95–95–95” target set by UNAIDS to combat the AIDS epidemic.
The Role of LDH levels in Predicting Viral Suppression
The study enrolled 393 ART-naive patients in a retrospective cohort, focusing on the association between lactate dehydrogenase (LDH) levels, time to viral suppression, and viral suppression outcomes. Using Cox regression analysis, researchers found that while LDH levels did not impact the overall viral suppression rate, they were a reliable predictor of the time to first viral load suppression.
“LDH levels proved to be a reliable predictor of time to first viral load suppressed in PLWH, which was self-reliant of ART regimen, baseline viral load, or other indicators,” the study noted.
This finding underscores the potential of LDH as a prognostic indicator, offering clinicians a valuable tool to tailor treatment plans for individual patients.
Comparing ART Regimens: STRs vs. MTRs
The study also compared the efficacy of different antiretroviral therapy (ART) regimens, particularly single-tablet regimens (STRs) and multi-tablet regimens (MTRs). STRs, which combine several antiretroviral drugs into a single dose, simplify dosing schedules and have been linked to improved adherence.
“INSTI-based STRs showed the highest efficacy in achieving viral suppression compared with other ART regimens,” the researchers reported.
However, the relationship between STRs and viral suppression remains a topic of debate. While five studies highlighted the positive impact of STRs on viral suppression,two found no significant correlation.the study emphasized that improved adherence to STRs likely plays a pivotal role in enhancing viral suppression outcomes.
INSTIs: A Game-Changer in HIV Treatment
Integrase strand transfer inhibitors (INSTIs) emerged as a standout in the study, demonstrating faster viral suppression compared to other antiretroviral drugs like protease inhibitors (PIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs).
“INSTI-based regimens are highly effective across diverse populations, including pregnant individuals, those with drug-resistant HIV strains, and individuals with suboptimal adherence,” the study noted.
This versatility makes instis a promising option for a wide range of patients,further solidifying their role in modern HIV treatment.
