Complex treatment situations you may encounter:
Intermittent, Suboptimal, or Poor Adherence
The DHHS guidelines highlight that the risk of drug resistance increases in patients with adherence issues, and that many common factors lead to adherence issues, placing patients at risk1
Rapid Initiation Scenarios
According to the DHHS guidelines, in cases where treatment is to be initiated before resistance testing is available, ARV therapies such as darunavir are recommended1
Unknown Resistance Testing Records
Per DHHS guidelines, in the absence of resistance testing records for treatment-naïve and virologically suppressed patients, assessing important patient and/or viral characteristics is difficult. In these situations, a regimen with a high genetic barrier to resistance can play an important role1
Intermittent, Suboptimal, or Poor Adherence1-7
Common real-world factors can lead to uncertain adherence
- Complex regimen
- Low levels of health literacy
- Busy or irregular lifestyle
- Current substance abuse
- Mental health issues (eg, stress, depression)
- Psychosocial issues (eg, low social support, stigma of HIV)
- Young age
- Nondisclosure of HIV status
- Nonadherence to clinical appointments
- Difficulty with taking medication
- Absence of HIV-1 symptoms
- Transition from jail/prison
- Lack of access to transportation
- Fallen out of care
- Cost and insurance issues
- Co-pays and prior approval of medications
- Maintaining pharmacy benefit
Rapid Initiation Has Been Shown to Improve Outcomes
The benefits of engaging and rapidly treating people newly diagnosed with HIV into care may include:
- Virologic suppression8
- Retention in care9
- Time to achieve virologic suppression10
Safety data on rapid initiation, data on intermediate or long-term outcomes, and data from randomized, controlled trials conducted in high-resource settings are currently lacking1.
The WHO recommends rapid initiation for all people newly diagnosed with HIV-111
According to the DHHS guidelines, treatment can begin regardless of CD4+ cell count, and before resistance testing results are available for patients willing and ready to begin1.
- Treatment may be deferred on a case-by-case basis, due to clinical psychosocial factors1
The DHHS guidelines recommend a regimen with a high genetic barrier to resistance, such as those containing darunavir, in rapid initiation scenarios1
- Data regarding resistance to INSTI-based regimens and the efficacy of DTG-based regimens in early HIV infection are more limited
Prior to or when initiating SYMTUZA®, test patients for hepatitis B (HBV) virus infection.
Prior to or when initiating SYMTUZA®, and during treatment with SYMTUZA®, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus.
Unknown Resistance Testing Records
Some clinical situations where patients may present without HIV genotypic resistance testing records:
- Patient may have refused care at time of initial diagnosis
- Resistance testing not performed at time of diagnosis
- Unable to locate prior resistance records
- Acute or recent HIV infection
Virologically suppressed patients
Known failure on previous regimens, but regimen type and resistance records not readily available
- May not have been performed at time of failure
- May not be able to locate previous genotypes if patient had transferred care
- Viral load too low to conduct resistance testing at the time of failure
The DHHS guidelines recommend a regimen with a high genetic barrier to resistance, such as those containing darunavir, while awaiting resistance testing results or if no ARV history is available.1
