Insights
Cognitive Behavioral Therapy for Adherence and Depression (CBT-AD) improved adherence and depression in HIV patients with substance use disorders. Gains in depression were maintained post-treatment, but adherence benefits diminished without continued support.
Area of Science:
- Clinical Psychology
- Infectious Diseases
- Addiction Medicine
Background:
- HIV, depression, and substance use are common comorbidities impacting treatment adherence.
- Injection drug use is prevalent among individuals with HIV globally.
- Effective interventions are needed to manage these co-occurring conditions.
Purpose of the Study:
- To evaluate the efficacy of Cognitive Behavioral Therapy for Adherence and Depression (CBT-AD) versus enhanced treatment as usual (ETAU).
- To assess CBT-AD's impact on adherence and depression in patients with HIV, depression, and active injection drug use.
- To examine outcomes at post-treatment and at 3- and 6-month follow-ups.
Main Methods:
- A randomized controlled trial with 89 participants was conducted.
- Two arms compared CBT-AD with ETAU.
- Adherence was measured using MEMS, and depression via blinded assessments.
Main Results:
- CBT-AD significantly improved adherence and reduced depression symptoms post-treatment compared to ETAU.
- Depression improvements were sustained at follow-up, but adherence gains were not.
- CBT-AD also led to significant improvements in CD4 cell counts over time.
Conclusions:
- CBT-AD effectively integrates depression treatment with adherence interventions for complex HIV patients.
- While CBT-AD shows initial benefits, ongoing adherence support is crucial for sustained gains.
- This approach offers a valuable strategy for managing multifaceted health challenges in this population.
Objective:
Depression and substance use, the most common comorbidities with HIV, are both associated with poor treatment adherence. Injection drug users comprise a substantial portion of individuals with HIV in the United States and globally. The present study tested cognitive behavioral therapy for adherence and depression (CBT-AD) in patients with HIV and depression in active substance abuse treatment for injection drug use.
Method:
This is a 2-arm, randomized controlled trial (N = 89) comparing CBT-AD with enhanced treatment as usual (ETAU). Analyses were conducted for two time-frames: (a) baseline to post-treatment and (b) post-treatment to follow-up at 3 and 6 months after intervention discontinuation.
Results:
At post-treatment, the CBT-AD condition showed significantly greater improvement than ETAU in MEMS (electronic pill cap) based adherence, γslope = 0.8873, t(86) = 2.38, p = .02; dGMA-raw = 0.64, and depression, assessed by blinded assessor: Mongomery-Asberg Depression Rating Scale, F(1, 79) = 6.52, p < .01, d = 0.55; clinical global impression, F(1, 79) = 14.77, p < .001, d = 0.85. After treatment discontinuation, depression gains were maintained, but adherence gains were not. Viral load did not differ across condition; however, the CBT-AD condition had significant improvements in CD4 cell counts over time compared with ETAU, γslope = 2.09, t(76) = 2.20, p = .03, dGMA-raw = 0.60.
Conclusions:
In patients managing multiple challenges including HIV, depression, substance dependence, and adherence, CBT-AD is a useful way to integrate treatment of depression with an adherence intervention. Continued adherence counseling is likely needed, however, to maintain or augment adherence gains in this population.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
