C-Reactive Protein as an Independent Cardiovascular Risk Predictor in HIV+ Patients: A Focused Review of Published...

Area of Science:

• Cardiology
• Infectious Diseases
• Biomarkers

Background:

• Patients with human immunodeficiency virus (HIV+) are living longer but face increased cardiovascular event (CVE) risk.
• Current CVE prediction tools may inaccurately assess risk in the HIV+ population.
• Inflammation markers could improve CVE risk prediction in HIV+ individuals.

Purpose of the Study:

• To review existing evidence on the association between high-sensitivity C-reactive protein (hs-CRP) and CVEs in treated HIV+ patients.
• To determine if hs-CRP could be a valuable addition to cardiovascular risk models for stable, treated HIV+ individuals.

Main Methods:

• A systematic literature search was conducted using PubMed with keywords "HIV", "cardiovascular risk", and "CRP".
• Included studies analyzed hs-CRP as an independent variable predicting hard cardiovascular outcomes or composite CVE endpoints.
• Five observational studies met the inclusion criteria for this review.

Main Results:

• Three of the five reviewed studies found a significant association between elevated hs-CRP levels and increased CVE risk.
• Two studies did not find a significant association, highlighting heterogeneity in study designs and endpoints.
• Larger, more rigorous studies with better confounder control and objective endpoints showed positive associations.

Conclusions:

• The evidence, while not conclusive, suggests hs-CRP is a potentially valuable biomarker for cardiovascular risk prediction in HIV+ patients.
• Further prospective studies are warranted to validate the role of hs-CRP in refining cardiovascular risk assessment for this population.
