Prevalence and Characteristics of CAM Use among People Living with HIV and AIDS in Lebanon: Implications for Patient Care

This study aimed to assess the prevalence and determinants of Complementary and Alternative Medicine (CAM) use among People Living with HIV and AIDS (PLWHA) in Lebanon and to identify related issues that may affect patient care. A cross-sectional survey design was used to interview 116 PLWHA in Beirut. The questionnaire addressed sociodemographic and disease characteristics as well as CAM use. The main outcome of the study was CAM use since diagnosis. Data analysis included descriptive statistics and logistic regression analyses. Overall, 46.6% of participants reported using one or more CAM therapies, with herbs and herbal products being the most commonly used (63%). A higher education level was associated with a 3-fold increase in the odds of CAM use. Among users, 20% used CAM as alternative to conventional treatment, 48% were not aware of CAM-drug interactions, 89% relied on nonhealth care sources for their choice of CAM, and 44% did not disclose CAM use to their physician. CAM use is prevalent among Lebanese PLWHA. Findings of this study highlighted the need to educate health care practitioners to have an open communication and a patient-centered approach discussing CAM use during routine care and to enhance awareness of PLWHA on safe use of CAM.

A review of the use of complementary and alternative medicine and HIV: issues for patient care

HIV/AIDS is a chronic illness, with a range of physical symptoms and psychosocial issues. The complex health and social issues associated with living with HIV mean that people living with HIV/AIDS (PLWHA) have historically often turned to complementary and alternative medicine (CAM). This article provides an overview of the literature on HIV and CAM. Databases were searched using keywords for CAM and HIV from inception to December 2012. Articles in English and in Western countries were included; letters, commentaries, news articles, articles on specific therapies and basic science studies were excluded. Of the 282 articles identified, 94 were included. Over half reported prevalence and determinants of CAM use. Lifetime use of CAM by PLWHA ranged from 30% to 90%, with national studies suggesting CAM is used by around 55% of PLWHA, practitioner-based CAM by 15%. Vitamins, herbs, and supplements were most common, followed by prayer, meditation, and spiritual approaches. CAM use was predicted by length of time since HIV diagnosis, and a greater number of medications/symptoms, with CAM often used to address limitations or problems with antiretroviral therapy. CAM users rarely rejected conventional medicine, but a number of CAM can have potentially serious side effects or interactions with ART. CAM was used as a self-management approach, providing PLWHA with an active role in their healthcare and sense of control. Clinicians, particularly nurses, should consider discussing CAM with patients as part of patient-centered care, to encourage valuable self-management and ensure patient safety.

HIV: effectiveness of complementary and alternative medicine

Outcome studies examining the efficacy of CAM among people living with HIV-AIDS are often conducted among small sample sizes with very little follow-up data or time points. Generalizability of many of the study findings is further limited by participant attrition. It is difficult to conduct clinical studies on chronically ill patients without participants dropping out, typically because the study demands coupled with their illness become too burdensome. Several studies have been conducted that include control groups, double-blind designs, and randomization. These scientifically sound studies have demonstrated promising results that strongly indicate a need for further research with larger samples in a prospective research design so that safety and efficacy can be determined over time. Many of the studies with small sample sizes reported trends, but did not find statistical significance. Increasing sample sizes in future studies is necessary to evaluate the scientific merit of these trends. Moreover, researchers need to evaluate the clinical and statistical significance in CAM use. The psychologic benefits of taking CAM should not be underestimated. For the purposes of this article, the authors did not include psychologic outcomes; however, there is evidence suggesting that decreasing depression can decrease HIV-related somatic complaints [69]. Studies need also to examine the effectiveness of CAM on psychologic outcomes and physical outcomes. This article and the authors' own research (Gore-Felton C et al, unpublished data) have revealed a high prevalence of alternative supplement use in conjunction with HIV medication, indicating an urgent need to understand the health benefits and the health risks of alternative supplements among patients with HIV and AIDS. Patients and physicians need more empirically based research to examine the toxicities, interactions, and health benefits of CAM. Many patients do not report the use of CAM to their physicians and very few physicians record treatments in the clinical record [70]. This will likely change as CAM becomes more widely recognized as a legitimate medical intervention; however, controlled outcome studies among large, diverse samples of people living with HIV-AIDS are needed. Health care providers need to assess the use of herbal and alternative therapy practices by their patients. Some patients may not be aware that they are taking a supplement or plant-based herb. Furthermore, some patients may believe that they are using something innocuous and even healthy simply because it came from a health food store. Understanding the contraindications of alternative therapies is necessary to prevent deleterious outcomes and to facilitate the safe and efficacious use of CAM in the management of HIV disease and related symptoms. As the epidemic in the United States continues to rise among women and minority populations, clinical research trials must include ethnically diverse patient populations that are gender balanced. Current available studies indicate that many CAM interventions may improve the quality of life of people living with HIV-AIDS; however, further studies using longitudinal, controlled designs are needed to accurately assess the safety of such interventions.
