  Purpose

In southern Africa, TB is the most common first AIDS-defining condition. Initiating Antiretroviral therapy (ART) in HIV positive TB patients will lead to the inclusion of the majority of HIV/AIDS patients currently fulfilling the criteria for therapy. Establishing an effective intervention to increase treatment adherence in this group is essential for the successful roll out of ART in the region. This proposed randomized controlled study aims to compare the effectiveness of two adherence support programmes (ASP) for use in patients with HIV-related TB in the context of CAPRISA AIDS Treatment (CAT)programme in KwaZulu-Natal, South Africa; the enhanced adherence support programme (E-ASP) or the standard adherence support programme (S-ASP).

S-ASP consists of three counselor presented, group education sessions. E-ASP is an extension of S-ASP and is based on the Information-Motivation-Behavioral Skills (IMB) Model of Adherence to Antiretroviral Therapy, a theoretical model initially developed to reduce HIV risk behavior. The E-ASP will consist of several interconnected components: 1) development and maintenance of an educational and supportive milieu at the CDC Clinic, 2) provision of five structured educational, support and behavioral skills building sessions, and (3) three weekly ART planning sessions.

Primary Outcome Measures:
  • suppressed viral load at 9 months [ Time Frame: 9 months ] [ Designated as safety issue: No ]
    Those participants with suppressed viral load at 9 months will be classed as treatment success, all others will be classed as treatment failures for the purposes of this outcome.


Secondary Outcome Measures:
  • feasibility of E-ASP in this resource constrained setting [ Time Frame: one year ] [ Designated as safety issue: No ]
  • Secondly to describe the relationship between adherence and viral load and CD4+counts [ Time Frame: 2 months, 9 months and 12 months ] [ Designated as safety issue: No ]
  • describe factors associated with poor/good adherence in this group [ Time Frame: one year ] [ Designated as safety issue: No ]
  • describe the relationship between early adherence and adherence at subsequent timepoints [ Time Frame: 2 weeks, and 2 and 9 months after start ART and 12 months ] [ Designated as safety issue: No ]
  • to establish the validity of self-reported adherence (in relation to pill counts) in this context [ Time Frame: one year ] [ Designated as safety issue: No ]
  • to assess the long-term impact of E-ASP on adherence [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • suppressed viral load at 12 months [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Those participants with suppressed viral load will be classed at treatment successes, all others will be classed as treatment failures for this secondary outcome measure.

  • adherence at 6 months [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1
enhanced adherence support for patients initiating antiretroviral therapy
 Behavioral: Enhanced adherence support
The enhanced adherence support intervention consists of 5 one-on-one, Information-Motivation-Behavioral Skills (IMB) theory-based counseling sessions, as well as a problem-solving card which summarizes key messages and strategies. The counseling sessions are given at key points post-initiation of therapy: at baseline, 2 weeks, 2 months, 3 months, and 6 months. Three brief weekly ART planning sessions are conducted post-initiation of therapy.
Active Comparator: 2
standard adherence support
 Behavioral: Standard adherence support
The control arm receives the standard of care adherence support which consists of three group counseling adherence sessions conducted prior to initiation of therapy.
