Frailty syndrome is commonly seen in the aged and reflects multi-system physiological change. However, with reduced functional reserve and resilience frailty is also known to be common in the HIV infected population. This study outlined an easily administered screening test to identify HIV patients with frailty. When significant components of frailty are identified, clinicians will be able to focus on amelioration of the problem and promote reversion to the pre-frail state.

Persons infected with HIV are often frail, depressed and live a sedentary lifestyle for which conventional exercise is too taxing. Here, we present an exercise protocol that ameliorates aspects of frailty in HIV-infected persons. An exergame integrating cognitive control was developed using biosensors that measured balance, weight-shifting and obstacle crossing.

Quantifying levels of HIV-1 RNA in plasma and sequencing single HIV-1 genomes from individuals with viral loads below the limit of detection (50-75 copies/ml) is difficult. Here we describe how to extract and quantify plasma viral RNA using a real time PCR assay that reliably measures HIV-1 RNA down to 0.3 copies/ml and how to amplify viral genomes by single genome sequencing, from samples with very low viral loads.
FAQs
Even when antiretroviral therapy controls viral replication, persistent immune activation and inflammation may continue to reduce physiological reserve. HIV frailty therefore reflects more than current viral burden: chronic inflammatory effects can combine with HIV-related comorbidities, medication burden, and age-associated changes in muscle and function. This multifactorial mechanism explains why vulnerability may remain relevant during effective treatment.
HIV-related comorbidities and the cumulative burden of medications can act alongside chronic inflammation and immune activation, increasing demands on an already limited physiological reserve. Their combined effects may contribute to reduced strength, exhaustion, slower movement, or declining activity. Considering these contributors together helps clinicians avoid viewing frailty as an isolated consequence of HIV infection alone.
Age-associated loss of muscle and physiological reserve can reduce the capacity to withstand minor stressors. In people living with HIV, these changes may intersect with inflammation, comorbidities, and medication burden, producing greater vulnerability than any single factor would suggest. This connection makes HIV frailty especially relevant to research and care focused on aging, function, and prevention of disability.
Recognition relies on identifying a pattern of reduced strength, slower movement, exhaustion, weight loss, and diminished physical activity, then placing those findings within the person’s broader medical context. Comprehensive geriatric assessment can organize this evaluation and help identify vulnerability, contributing conditions, and care needs. The resulting assessment supports risk prediction rather than relying on one isolated symptom.
Care should be individualized and extend beyond viral control. The overview identifies nutrition, exercise, mental health, and medication management as important areas for attention. Addressing these domains allows clinicians to consider physical function, emotional well-being, dietary needs, and treatment burden together, creating a broader strategy for maintaining reserve and reducing the risk of disability.
Assessment can support risk prediction and reveal how vulnerability relates to a person’s strength, movement, energy, weight, activity, and wider health status. It also helps guide individualized care decisions by showing where additional attention may be needed. In this way, frailty assessment adds functional and geriatric context to routine medical management of people living with HIV.
HIV frailty provides a framework for studying how chronic immune activation, inflammation, comorbidities, treatment burden, and age-related loss of reserve intersect. Research in this area can inform strategies for healthy aging and prevention of disability among people living with HIV. It also connects HIV medicine with broader geriatric goals, including preserving function and adapting care to individual vulnerability.
