Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Approximately 500 subjects were surveyed from the HIVNAT 006 long term follow up cohort. A sample size as large as this is likely to yield accurate results as to the true relationship between sexual risk behavior and adherence to HIV medications.

Who may be able to join

  • Age ≥ 18 years
  • HIV seropositive.
  • On continuous HAART for at least 6 months
  • Signed written informed consent

About this study

Study Hypothesis: Do certain risk behaviours impact/predict levels of HIV antiretroviral adherence?

Objectives:

  • To assess risk behavior in HIV-positive individuals receiving highly active antiretroviral therapy.(HAART)
  • To assess levels of adherence in the same subjects at the same time point
  • To determine if there is a correlation between HAART adherence and risk behaviour
Read the detailed description

Background and Rationale:

Adherence to an effective antiretroviral (ARV) regimen is the most important determinant of treatment success in patients receiving ARV. It is now well established that virological suppression on highly active antiretroviral therapy (HAART) requires strict adherence to prescribed dosing schedules. It is essential to reach and maintain therapeutic levels of these drugs, and strict adherence is particularly crucial for preventing the development of drug-resistant viral strains. If therapeutic drugs levels are suboptimal and the virus is able to replicate, this has important individual and public health implications.

Indirect evidence also suggests that the use of HAART by HIV-infected individuals decreases sexual transmission of HIV. Specifically, ARV treatment decreases serum and genital fluid HIV viral load. It has become evident that the availability of HAART may paradoxically increase sexual practices that lead to HIV transmission. This has been seen in several developed countries where the introduction of HAART coincided with increasing sexual risk behaviour and sexually transmitted infections. Thus far there has been very little evidence showing these trends in developing countries.

Despite the high burden on HIV in developing countries compared with developed countries, considerably more evidence is available in the latter regarding adherence and risk behaviour. Studies to ascertain the correlation between these two factors are important as new interventions may be established to ensure that improved health and economic outcomes will follow. Understanding which patients have increased risk behaviours, or are at risk for non-adherence enables identification of patients who are important targets for interventional strategies to optimise HIV treatment programmes.

Adherence and risk behaviour:

Apart from the beneficial clinical effects of HAART, treatment advances may have unintended effects on sexual behaviour. Evidence suggests that since HAART became available, the prevalence of unprotected sex and the incidence of sexually transmitted infections including HIV have increased, mostly among men who have sex with men (MSM). Some HIV positive persons receiving HAART, especially those with a undetectable viral load, may feel protected from transmitting HIV sexually. Recent evidence does suggest that an undetectable viral load may reduce the level of infectiousness of HIV positive persons receiving HAART.

As this information moves into the public domain it may influence peoples beliefs about HIV transmission and lessen concern about engaging in unsafe sex. People who hold these beliefs are more likely than their counterparts to engage in unprotected sex.

HIV positive patients who engage in high-risk behaviours linked to HIV spread are as likely to be receiving HAART as those at low risk for disease transmission, but those who engage in high-risk behaviours have much lower rates of medication adherence and thus much higher viral loads. This suggests a strong behavioural basis for transmission of drug resistant HIV, and parallels recent increases in all sexually transmitted infections. Given that taking HAART and having an undetectable viral load do not eliminate the possibility of transmitting HIV, it is important to examine whether the use of HAART and beliefs about HAART are associated with sexual risk taking.

Definitions:

Risk behavior is defined as behavior which may result in transmission of HIV

Study subjects:

Subjects will be asked to complete a questionnaire which will contain questions on adherence and risk behaviour.At the completion of data collection an analysis will be made accordingly. Approximately 700 patients in HIV-NAT 006 who provide consent will be enrolled.

Inclusion criteria are:

  • Age ≥ 18 years
  • HIV seropositive.
  • On continuous HAART for at least 6 months
  • Signed written informed consent

Methods:

Cross sectional survey of adherence and behavior in subjects enrolled in the HIVNAT 006 long term follow up cohort.

Patients enrolled in HIVNAT 006 are normally required to attend regular 6 monthly follow up appointments. Over the coming months 700 subjects who give consent will be asked to complete an anonymous self-administered questionnaire at their next clinic visit. Completion of the questionnaire will be facilitated by people living with HIV/AIDS (PLHA) who will be trained by HIVNAT.

The questionnaire will comprise the following categories:

  1. Demographics
  2. Medication adherence
  3. Factors affecting adherence (risk behaviour)

Furthermore the following will be extracted from the HIVNAT database:

  • CDC disease stage over the previous 12 months and at current consult
  • CD4 over the previous 12 months and at current consult
  • VL over the previous 12 months and at current consult
  • ARV regimen and changes in regimen
  • Opportunistic infections

Study groupRoleWhat they receive
HIVNAT 006HIVNAT 006 is a long term follow up cohort. The primary objective of this study is to collect and evaluate the long-term clinical outcomes of HIV infected patients have participated in HIV-NAT studies. These subjects will be used to test our hypothesis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The relationship between sexual risk behavior and adherence to HIV medications and how do these behaviors relate to patient beliefs about HIV transmission.

    Measured: 2 Years

Questions about this trial

What is this clinical trial studying?

An observational study of HIV Infections, run by The HIV Netherlands Australia Thailand Research Collaboration at 1 site in Thailand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The relationship between sexual risk behavior and adherence to HIV medications and how do these behaviors relate to patient beliefs about HIV transmission. (time frame: 2 Years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00511056, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2020.
