Human Immunodeficiency Virus Viral Suppression Being Impacted By Buprenorphine

The use of an opioid is common among people living with the human immunodeficiency virus (HIV;  PLWH) and affects HIV outcomes harshly. The effect of the initiation of buprenorphine (BUP) on subsequent HIV viral loads was evaluated for a study. PLWH from the Johns Hopkins HIV Clinical Cohort was recognized who started BUP between 2002 and 2017. Poisson regression with robust variance was used to calculate the commonness of viral suppression (<200 copies/mL) before and after BUP beginning. Researchers matched individuals who started BUP with controls based on viral load measurement dates and prior event rate (PERR) methods to calculate the effect of BUP beginning on viral suppression. PERR methods accounted for the unmeasured confounders.

It was identified that 279 PLWH initiated BUP. PLWH was more certain to be virally suppressed (prevalence ratio [PR], 1.19; 95% CI, 1.03-1.37) after BUP initiation. After PLWH was matched, who was responsible for the initiation of BUP for controlling and accounting measured and unmeasured confounders, BUP initiation resulted in the increase of viral suppression for both on antiretroviral therapy (ART) at baseline (PERR PR, 1.08; 95% CI, 1.00-1.18) and those not on ART at baseline (PR, 1.31; 95% CI, 1.10-1.61).

During the Canada Post strike announced September 25, 2025, the following measures will be undertaken to minimize service disruption to BC-CfE clients and providers.

  • The BC-CfE Laboratory has transitioned to private courier for delivery of outgoing reports and documents. Results required urgently can be faxed upon request. (Lab Contact Information: Phone 604-806-8775; FAX 604-806-9463)
  • The BC-CfE Drug Treatment Program (DTP) will fax outgoing forms and documents to the provider’s office. (DTP Contact Information: Phone 604-806-8515; FAX 604-806-9044)
  • St. Paul’s Hospital Ambulatory Pharmacy has transitioned to private courier for delivery of medications. We recommend requesting medication at least 2 weeks in advance in case of delivery delays, particularly to rural/remote parts of BC. (Contact Information: Phone 1-800-547-3622; FAX 604-806-8675)

During the Canada Post strike, we recommend that documents be faxed or couriered to our sites, versus utilization of regular mail service

The BC-CfE Laboratory is streamlining reporting processes for certain tests in order to simplify distribution and record-keeping, and to ensure completeness of results. Beginning September 2, 2025, results for the ‘Resistance Analysis of HIV-1 Protease and Reverse Transcriptase’ (Protease-RT) and ‘HIV-1 Integrase Resistance Genotype’ tests will be combined into a single ‘HIV-1 Resistance Genotype Report’.
