Treatment Complexities Among Patients with Tuberculosis in a High HIV Prevalence Cohort in the United States

Abstract

The association between human immunodeficiency virus (HIV) infection and tuberculosis (TB) mortality has been studied extensively, but the impact of HIV on other clinically relevant aspects of TB care such as TB drug-related adverse events (AEs), hospital readmissions, and TB treatment duration is less well characterized. We describe the association of HIV infection with TB clinical complexities and outcomes in a high HIV prevalence cohort in the United States. This is a retrospective cohort study among patients treated for culture-confirmed TB between 2008 and 2015 at an inner-city hospital in Atlanta, GA. Univariate analysis was used to estimate association of HIV with TB treatment interruption due to AEs, hospital readmissions, and treatment duration. Final unfavorable TB treatment outcome was defined as death, loss to follow-up, or recurrent TB. Logistic regression modeling was used to estimate association of HIV with final unfavorable outcomes. Among 274 patients with TB, 96 (35%) had HIV coinfection. HIV-positive patients had more TB treatment interruptions due to AE (34% vs. 15%), were more likely to have a hospital readmission (50% vs. 21%), and received longer TB treatment (9.9 months vs. 8.8 months) compared to HIV-negative patients (p < .01 for all). HIV infection was not associated with final unfavorable outcomes in univariate [odds ratio (OR) = 1.86; confidence interval (95% CI) 0.99-3.49] or multivariate analysis (aOR = 1.13; 95% CI 0.52-2.39) (p ≥ .05 for both). While HIV infection was not associated with final unfavorable TB outcomes, TB/HIV coinfected patients had more complex treatment course underscoring the importance of maintaining resources and expertise to treat coinfected patients in our and similar settings.

Lack of latent tuberculosis screening in HIV patients and delay in Anti-Retroviral Therapy initiation in HIV-TB co-infection: A 11-year study in an intermediate TB-burden country

“…This is in keeping with a systematic review done in the European Union which reported that the majority of HIV-TB co-infected cases were male and young adults, aged between 25-45 years (15). We also found that the prevalence of diabetes mellitus (DM) in our cohort was 12% which was similar to a study conducted by Bizune et al in the United States, which reported a prevalence of 9% (16). The high proportion can be explained by diabetes predisposing to TB and ART increasing the risk of metabolic syndrome and thus predisposing to DM (17), and also underscores the increase in DM prevalence in developed countries.…”

Prevalence and associated risk factors of drug‐resistant tuberculosis in Thailand: results from the fifth national anti‐tuberculosis drug resistance survey

“…Based on a previous study, male sex has other predictors of non-compliance to TB treatment, for example, smoking history and drug abuse [21], while women have higher accessibility to TB care than men [22]. Treatment complexity is a primary consideration of poor compliance in TB/HIV coinfection [23,24]. Improvement in TB care in HIV patients could be achieved through mentoring and training programmes [25].…”

Influência do HIV nos desfechos desfavoráveis do tratamento da Tuberculose

“…Por conseguinte, na análise multivariada, a coinfecção pelo HIV apresentou a mesma Resultados de coorte realizada nos Estados Unidos, na qual utilizou modelagem de regressão logística para estimar a associação do HIV com desfechos desfavoráveis do tratamento da TB, também encontrou uma maior tendência de desfechos desfavoráveis em casos de coinfecção TB-HIV, contudo não mostrou associação estatisticamente significativa. Apesar disso, os pacientes coinfectados tiveram um curso de tratamento mais complexo (Bizune;.…”
