Hypothesis
What are the clinical outcomes for patients with sustained viral suppression compared to those with episodes of viremia?
Conclusion
Using repeat viral load measurements could prevent unnecessary switches to second-line treatment in many patients.
Supporting Evidence
- 71% of patients achieved sustained viral suppression.
- Patients with intermediate viremia had a higher switch rate to second-line treatment.
- Only 19% of patients with high viremia were switched to second-line therapy.
Takeaway
Doctors can help HIV patients stay on their first treatment longer by checking their virus levels more than once before changing their medicine.
Methodology
A prospective cohort study of patients on ART in Uganda, followed for 48 months, categorized by viral load.
Potential Biases
Potential bias due to lack of routine genotype resistance testing.
Limitations
The follow-up time may not have been long enough to assess the long-term effects of viremia on morbidity and mortality.
Participant Demographics
Patients were primarily from Uganda, with a median age of 35 years.
