To determine prevalence and predictors of complementary and alternative medicine (CAM) use disclosure to health care providers and whether CAM use disclosure is associated with highly active antiretroviral therapy (HAART) adherence among HIV-infected women, we analyzed longitudinal data collected between October 1994 and March 2002 from HIV-infected CAM-using women enrolled in the Women’s Interagency HIV Study. Repeated measures Poisson regression models were constructed to evaluate associations of selected predictors with CAM use disclosure and association between CAM use disclosure and HAART adherence. A total of 1377 HIV-infected women reported CAM use during study follow-up and contributed a total of 4689 CAM-using person visits. The overall prevalence of CAM use disclosure to health care providers was 36% across study visits. Women over 45 years old, with a college education, or with health insurance coverage were more likely to disclose their CAM use to health care providers, whereas women identified as non-Hispanic Black or other ethnicities were less likely to communicate their CAM usage. More health care provider visits, more CAM domains used, and higher health care satisfaction scores had significant relationships with increased levels of CAM use disclosure. Restricting analysis to use of herbal or nonherbal medications only, similar results were obtained. Compared to other CAM domains, mind–body practice had the lowest prevalence of CAM use disclosure. Additionally, CAM use disclosure was significantly associated with higher HAART adherence. From this study, we showed that a high percentage of HIV-infected women did not discuss their CAM use with health care providers. Interventions targeted towards both physicians and patients may enhance communication of CAM use, avoid potential adverse events and drug interactions, and enhance HAART adherence.

Summary
Background
A cross-sectional survey was conducted in order to define the prevalence, pattern, and predictors of complementary and alternative medicine (CAM) use in breast cancer patients in northwestern Turkey.
Patients and Methods
All patients admitted to the breast center between January 2005 and January 2006 were consecutively included in the study. Demographics and clinical data of study patients were noted. A 15-item questionnaire was used to document the attitude of breast cancer patients towards CAM modalities. Primary outcomes were prevalence, pattern, and predictors of CAM. Secondary outcomes were the reasons for CAM use, the number and type of adverse events related to CAM use, and the satisfaction level of CAM users.
Results
Nearly one third of breast cancer patients use at least one type of CAM in addition to conventional therapy. Most chose herbal medicines which they think support their general health status. Nettle (Urtica diocia/U. urens) was the most common herbal medicine that patients consume. Previous experience with CAM was the most significant factor for CAM use after breast cancer diagnosis. Being young and married as well as receiving radiotherapy were among other independent factors for using any CAM modality.

Background
In the early highly active antiretroviral therapy (HAART) era, kidney dysfunction was strongly associated with death among HIV-infected individuals. We re-examined this association in the later HAART period to determine whether chronic kidney disease (CKD) remains a predictor of death after HAART-initiation.
Methods
To evaluate the effect of kidney function at the time of HAART initiation on time to all-cause mortality, we evaluated 1415 HIV-infected women initiating HAART in the Women’s Interagency HIV Study (WIHS). Multivariable proportional hazards models with survival times calculated from HAART initiation to death were constructed; participants were censored at the time of the last available visit or December 31, 2006.
Results
CKD (eGFR <60 ml/min/1.73 m2) at HAART initiation was associated with higher mortality risk adjusting for age, race, hepatitis C serostatus, AIDS history and CD4+ cell count (hazard ratio [HR]=2.23, 95% confidence interval [CI]: 1.45–3.43). Adjustment for hypertension and diabetes history attenuated this association (HR=1.89, CI: 0.94–3.80). Lower kidney function at HAART initiation was weakly associated with increased mortality risk in women with prior AIDS (HR=1.09, CI: 1.00–1.19, per 20% decrease in eGFR).
Conclusions
Kidney function at HAART initiation remains an independent predictor of death in HIV-infected individuals, especially in those with a history of AIDS. Our study emphasizes the necessity of monitoring kidney function in this population. Additional studies are needed to determine mechanisms underlying the increased mortality risk associated with CKD in HIV-infected persons.

Use of complementary and alternative medicine (CAM) is prevalent among HIV+ individuals despite the success of antiretroviral treatments and limited evidence of CAM's safety and efficacy. To characterize the potential impact of CAM use on HIV care, we conducted a systematic review of 40 studies of CAM use among HIV+ people. The goals of this review are to: (a) describe the demographic, biomedical, psychosocial, and health behavior correlates of CAM use; (b) characterize patient-reported reasons for CAM use; and (c) identify methodological and conceptual limitations of the reviewed studies. Findings confirm that a high proportion of HIV+ individuals report CAM use (M = 60%). Overall, CAM use is more common among HIV+ individuals who are men who have sex with men (MSM), non-minority, better educated, and less impoverished. CAM use is also associated with greater HIV symptom severity and longer disease duration. HIV+ CAM users commonly report that they use CAM to prevent or alleviate HIV-related symptoms, reduce treatment side-effects, and improve quality of life. Findings regarding the association between CAM use, psychosocial adjustment, and adherence to conventional HIV medications are mixed. While the reviewed studies are instrumental in describing the characteristics of HIV+ CAM users, this literature lacks a conceptual framework to identify causal factors involved in the decision to use CAM or explain implications of CAM use for conventional HIV care. To address this concern, we propose the use of health behavior theory and discuss implications of review findings for HIV care providers.

Abstract
Objectives
The objectives of this study were to explore the association between complementary and alternative medicine (CAM) use as reported by youth, and parents' and children's reported quality of life in youth with diabetes.
Design
The study design was a cross-sectional survey.
Setting
Youth in Washington State participated in the SEARCH for Diabetes in Youth study, a national, multisite epidemiological study designed to assess the prevalence and incidence of diabetes in U.S. youth. Surveys assessing CAM utilization were mailed in January and April 2006.
Participants
One thousand four hundred and thirty-nine (1439) youth were mailed a CAM survey. The final sample consisted of 467 youth with both CAM survey results and quality-of-life data.
Outcome measures
Difference in mean scores on Pediatric Quality of Life Inventory (PedsQL) between CAM users and nonusers overall, and specific CAM therapies were the outcome measures.
Results
Of the 1439 participants approached, 587 (40.8%) returned the CAM survey. In adjusted analyses, children reported any CAM use as associated with more barriers to treatment (difference in mean scores −3.48, 95% confidence interval [CI] −6.65, −0.31). Children following a CAM diet reported higher quality of life (PedsQL Core Total difference 4.01, 95% CI [0.10–7.91]; Core Psychosocial difference was 6.45, 95% CI [1.95 to 10.95]), but those using stress-reduction activities reported poorer quality of life (Diabetes Total difference −4.19, 95% CI [−8.35 to −0.04]). Parent-reported quality of life was lower for children who used “other supplements” (Core Total difference −6.26, 95% CI [−11.29 to −1.24]; Core Psychosocial difference was −5.92, 95% CI [−11.65 to −0.19]).
Conclusions
CAM diets were associated with increased quality of life in youth with diabetes, whereas supplement use and stress-reduction activities were associated with decreased quality of life. The temporal sequence between CAM use and quality of life requires further study.

The effects of highly active antiretroviral therapy (HAART) on progression of hepatic fibrosis in HIV-hepatitis C virus (HCV) co-infection are not well understood. Deaths from liver diseases have risen in the post-HAART era, yet some cross-sectional studies have suggested that HAART use is associated with improved fibrosis rates. In a retrospective cohort of 533 HIV mono-infected and 127 HIV/HCV co-infected patients, followed between January 1991 and July 2005 at a university-based HIV clinic, we investigated the relationship between cumulative HAART exposure and hepatic fibrosis, as measured by the aspartate aminotransferase-to-platelet ratio index (APRI). We used a novel methodological approach to estimate the dose-response relationship of the effect of HAART exposure on APRI. HAART was associated with increasing APRI over time in HIV/HCV co-infected patients suggesting that they may be experiencing cumulative hepatotoxicity from antiretrovirals. The estimated median change (95% confidence interval) in APRI per one year of HAART intake was of −0.46% (−1.61% to 0.71%) in HIV mono-infected compared to 2.54% (−1.77% to 7.03%) in HIV/HCV co-infected patients. Similar results were found when the direct effect of HAART intake since the last visit was estimated on the change in APRI. HAART use associated is with increased APRI in patients with HIV/HCV co-infection. Therefore treatment for HCV infection may be required to slow the growing epidemic of end-stage liver disease in this population.

Background
Complementary and alternative medicine (CAM) use is well documented among breast cancer patients and survivors, but little evidence is available to describe rates and patterns of use among women at increased genetic risk of breast cancer.
Methods
A pre-visit telephone interview was conducted to ascertain CAM use among the BRCA mutation carriers enrolled in a high-risk breast cancer screening study. Participants were asked to report on their use of thirteen therapies within the year prior to enrollment into the study. Logistic regression was used to evaluate the association between various factors and CAM use in this population.
Results
Among the 164 BRCA1 or BRCA2 mutation-positive (BRCA+) women in this analysis, 78% reported CAM use, with prayer and lifestyle diet being the two most commonly reported modalities. Many subjects used multiple CAM therapies, with 34% reporting use of three or more modalities. The most commonly used modalities were mind-body therapies and biologically-based practices, 61.6% and 51.8%, respectively. High-risk women were more likely to use CAM if they were older, more educated, more worried about ovarian cancer risk, or had a previous cancer diagnosis.
Conclusion
This study suggests that the prevalence of CAM use is high among BRCA mutation carriers, with frequency of use comparable to that of breast cancer patients and survivors. Given the high prevalence of CAM use in our subjects, especially biologically-based therapies including herbal supplements, whose safety and efficacy in relation to cancer risk are unknown, our study suggests that future research is necessary to clarify these risks, and that it is important for providers to inquire about and to discuss the pros and cons of CAM use with their BRCA+ patients.

Background
Complementary and alternative medicine (CAM) is widely used for the treatment of infertility. While the Middle East and North Africa region has been shown to house one of the fastest growing markets of CAM products in the world, research describing the use of CAM therapies among Middle-Eastern infertile patients is minimal. The aim of this study is to examine the prevalence, characteristics and determinants of CAM use among infertile patients in Lebanon.
Methods
A cross sectional survey design was used to carry out face-to-face interviews with 213 consecutive patients attending the Assisted Reproductive Unit at a major academic medical center in Beirut. The questionnaire comprised three sections: socio-demographic and lifestyle characteristics, infertility-related aspects and information on CAM use. The main outcome measure was the use of CAM modalities for infertility treatment. Determinants of CAM use were assessed through the logistic regression method.
Results
Overall, 41% of interviewed patients reported using a CAM modality at least once for their infertility. There was a differential by gender in the most commonly used CAM therapies; where males mostly used functional foods (e.g. honey & nuts) (82.9%) while females mostly relied on spiritual healing/prayer (56.5%). Factors associated with CAM use were higher household income (OR: 0.305, 95% CI: 0.132–0.703) and sex, with females using less CAM than males (OR: 0.12, 95% CI: 0.051–0.278). The older patients were diagnosed with infertility, the lower the odds of CAM use (p for trend <0.05). Almost half of the participants (48%) were advised on CAM use by their friends, and only 13% reported CAM use to their physician.
Conclusions
The considerably high use of CAM modalities among Lebanese infertile patients, added to a poor CAM use disclosure to physicians, underscore the need to integrate CAM into the education and training of health professionals, as well as enhance infertile patients' awareness on safe use of CAM products.

Background
The impact of highly active antiretroviral therapy (HAART) on health-related quality of life (QOL) of HIV-1 infected individuals in large prospective cohorts has not been well studied.
Objective
To assess the effect of HAART on QOL by comparing HIV-infected women using HAART with HIV-infected women remaining HAART naïve in the Women's Interagency HIV Study (WIHS), a multicenter prospective cohort study begun in 1994 in the US.
Methods
A 1:1 matching with equivalent (≤ 0.1%) propensity scores for predicting HAART initiation was implemented and 458 pairs were obtained. HAART effects were assessed using pattern mixture models. The changes of nine QOL domain scores and one summary score derived from a shortened version of the MOS-HIV from initial values were used as study outcomes.
Results
The background covariates of the treatment groups were well-balanced after propensity score matching. The 916 matched subjects had a mean age of 38.5 years and 42% had a history of AIDS diagnosis. The participants contributed a total of 4,292 person visits with a median follow-up time of 4 years. In the bivariate analyses with only HAART use and time as covariates, HAART was associated with short-term improvements of 4 QOL domains: role functioning, social functioning, pain and perceived health index. After adjusting for demographic, socioeconomic, biological and clinical variables, HAART had small but significant short-term improvements on changes in summary QOL (mean change: 3.25; P = 0.02), role functioning (6.99; P < 0.01), social functioning (5.74; P < 0.01), cognitive functioning (3.59; P = 0.03), pain (6.73; P < 0.01), health perception (3.67; P = 0.03) and perceived health index (4.87; P < 0.01). These QOL scores typically remained stable or declined over additional follow-up and there was no indication that HAART modified these trends.
Conclusion
Our study demonstrated significant short-term HAART effects on most QOL domains, but additional use of HAART did not modify long-term trends. These changes could be attributed to the direct effect of HAART and indirect HAART effect mediated through clinical changes.

Background
Pregnancy has been associated with a decreased risk of HIV disease progression in the highly active antiretroviral therapy (HAART) era. The effect of timing of HAART initiation relative to pregnancy on maternal virologic, immunologic and clinical outcomes has not been assessed.
Methods
We conducted a retrospective cohort study from 1997–2005 among 112 pregnant HIV-infected women who started HAART before (N = 12), during (N = 70) or after pregnancy (N = 30).
Results
Women initiating HAART before pregnancy had lower CD4+ nadir and higher baseline HIV-1 RNA. Women initiating HAART after pregnancy were more likely to receive triple-nucleoside reverse transcriptase inhibitors. Multivariable analyses adjusted for baseline CD4+ lymphocytes, baseline HIV-1 RNA, age, race, CD4+ lymphocyte count nadir, history of ADE, prior use of non-HAART ART, type of HAART regimen, prior pregnancies, and date of HAART start. In these models, women initiating HAART during pregnancy had better 6-month HIV-1 RNA and CD4+ changes than those initiating HAART after pregnancy (−0.35 vs. 0.10 log10 copies/mL, P = 0.03 and 183.8 vs. −70.8 cells/mm3, P = 0.03, respectively) but similar to those initiating HAART before pregnancy (−0.32 log10 copies/mL, P = 0.96 and 155.8 cells/mm3, P = 0.81, respectively). There were 3 (25%) AIDS-defining events or deaths in women initiating HAART before pregnancy, 3 (4%) in those initiating HAART during pregnancy, and 5 (17%) in those initiating after pregnancy (P = 0.01). There were no statistical differences in rates of HIV disease progression between groups.
Conclusions
HAART initiation during pregnancy was associated with better immunologic and virologic responses than initiation after pregnancy.

Background
The purpose of this study was to determine, among the Indian community of Chatsworth, South Africa, the prevalence and utilisation patterns of complementary and alternative medicine (CAM), attitudes associated with CAM use and communication patterns of CAM users with their primary care doctors.
Methods
Face-to-face structured interviews were conducted in Chatsworth, a suburb of Durban in which South Africans of Indian origin predominantly reside. Participants were 200 randomly selected adult English-speaking Indian residents.
Results
The prevalence of CAM usage for period 2000/2001 was 38.5% (95% confidence interval 31.7% to 45.6%). Spiritual healing and herbal/natural medicines, including vitamins were the most common types of CAM used, accounting for 42.8% and 48.1% respectively of overall CAM usage. People used CAM to treat conditions including diabetes mellitus, headaches, arthritis and joint pains, stress, skin disorders, backaches, hypertension and nasal disorders. Half of the CAM users used allopathic medicines concurrently. The cost of CAM utilization over this 1-year period, incurred by 80.5% of users for the duration of therapy for their most troublesome condition was below R500 (approximately US$50). Age, sex, marital status, religion, level of education and income were shown not to influence the use of CAM. Greater than half (51.9%) of CAM users did so either upon the advice of someone they knew, or after noticing a CAM advertisement in the local press. Seventy-nine percent of CAM users indicated that they had positive outcomes with their treatments. Fifty four percent of CAM users (excluding those using spiritual healing only) failed to inform their doctors that they used CAM. The main reason given by half of this group was that informing their doctors did not seem necessary.
Conclusion
The prevalence of CAM in Chatsworth is similar to findings in other parts of the world. Although CAM was used to treat many different ailments, this practice could not be attributed to any particular demographic profile. The majority of CAM users were satisfied with the effects of CAM. Findings support a need for greater integration of allopathic medicine and CAM, as well as improved communication between patients and caregivers regarding CAM usage.

Background
Infertility patients are a vulnerable group that often seeks a non-medical solution for their failure to conceive. World-wide, women use CAM for productive health, but only a limited number of studies report on CAM use to enhance fertility. Little is known about traditional and religious forms of therapies that are used in relation to conventional medicine in Turkey. We investigated the prevalence and types of complementary and alternative medicine (CAM) used by infertile Turkish women for fertility enhancement.
Methods
A face-to-face questionnaire inquiring demographic information and types of CAM used for fertility enhancement were completed by hundred infertility patients admitted to a primary care family planning centre in Van, Turkey between January and July 2009.
Results
The vast majority of infertile women had used CAM at least once for infertility. CAM use included religious interventions, herbal products and recommendations of traditional "hodja's" (faith healers). Of these women, 87.8% were abused in the last 12 months, 36.6% felt not being supported by her partner and 80.5% had never spoken with a physician about CAM.
Conclusions
Infertile Turkish women use complementary medicine frequently for fertility enhancement and are in need of information about CAM. Religious and traditional therapies are used as an adjunct to, rather than a substitute for, conventional medical therapy. Physicians need to approach fertility patients with sensitivity and should be able to council their patients about CAM accordingly.

Background
The present study describes Complementary and Alternative Medicine (CAM) use amongst Italian women transitioning through menopause. Popularity and perceived effectiveness of CAM treatments, use of pharmaceutical medications, characteristics of CAM users, the extent of communication between medical practitioners and women about their use of CAM, and variables associated with CAM use were also investigated.
Methods
Women, aged 45-65 years attending Family Planning and Women's Health clinics or Menopause Centres in Bologna were invited to complete a voluntary, anonymous, self administered questionnaire, which was used in a previous study in Sydney. The questionnaire was translated and adapted for use amongst Italian women. Data on general demographic and health characteristics, menopause related symptoms and the use of CAM and pharmaceutical treatments during the previous 12 months were collected.
Results
In total, 1,203 women completed the survey, of which 1,106 were included in the final sample. Of women who had symptoms linked with menopause and/or used remedies to alleviate symptoms, 33.5% reported to have used CAM. Among these, 23.5% had consulted one or more practitioners and 24% had used at least one CAM product.
Approximately nine out of ten respondents reported medical practitioners did not seek information about their use of CAM; while one third of CAM users did not disclose the use of CAM to their physician. Nevertheless, medical practitioners were the most popular source of information. From the multivariate analysis, variables associated with CAM use were: professional employment, time since the last natural menses, use of CAM for conditions other than menopause, and presence of some severe symptoms.
Conclusions
The relatively high prevalence of CAM use by women transitioning through menopause should encourage research initiatives into determining which CAM treatments are the safest and effective. The increasing and likely concomitant use of CAM with HRT and other pharmaceuticals underlines the need for the implementation of a surveillance system to report and monitor possible drug-herb adverse events. The discrepancy between women preferring to seek information about CAM from their medical doctor and the difficulties noted in communication between doctor and patient should encourage educational initiatives on CAM by health-care agencies and institutions.

Background
The popularity of complementary and alternative medicine (CAM) has led to a growing amount of research in this area. All the same little is known about the effects of these special treatments in every-day practice of primary care, delivered by general practitioners within the health insurance system. From 1994 to 2000 more than 20 German Company health insurances initiated the first model project on CAM according to the German social law. Aim of this contribution is to investigate the effectiveness of multi-modal CAM on chronic diseases within primary health care.
Methods
A long-term prospective intermittent study was conducted including 44 CAM practitioners and 1221 self-selected chronically ill patients (64% women) of whom 441 were employed. Main outcome measure is sick-leave, controlled for secular trends and regression-to-the mean and self-perceived health status.
Results
Sick-leave per year of 441 patients at work increased from 22 (SD ± 45.2) to 31 (± 61.0) days within three years prior to intervention, and decreased to 24 (± 55.6) in the second year of treatment, sustaining at this level in the following two years. Detailed statistical analysis show that this development exceeds secular trends and the regression-toward-the-mean effect. Sick-leave reduction was corroborated by data on self-reported improvement of patients' health status.
Conclusion
Results of this longterm observational study show a reduction of sick leave in chronically ill patients after a complex multimodal CAM intervention. However, as this is an uncontrolled observational study efficacy of any specific CAM treatment can not be proven. The results might indicate an general effectiveness of CAM in primary care, worthwhile further investigations. Future studies should identify the most suitable patients for CAM practices, the most appropriate and safe treatments, provide information on the magnitude of the effects to facilitate subsequent definitive randomised controlled studies that will help to position complementary and alternative medicine in health care.

Background
Complementary and alternative medicine (CAM) use is common among cancer patients. This paper reviews the use of CAM in a series of patients with locally advanced breast cancer (LABC).
Methods
Women with LABC attending a specialist clinic at a single Canadian cancer centre were identified and approached. Participants completed a self-administered survey regarding CAM usage, beliefs associated with CAM usage, views of their risks of developing recurrent cancer and of dying of breast cancer. Responses were scored and compared between CAM users and non-users.
Results
Thirty-six patients were approached, 32 completed the questionnaire (response rate 89%). Forty-seven percent of LABC patients were identified as CAM users. CAM users were more likely to be younger, married, in a higher socioeconomic class and of Asian ethnicity than non-users. CAM users were likely to use multiple modalities simultaneously (median 4) with vitamins being the most popular (60%). Motivation for CAM therapy was described as, "assisting their body to heal" (75%), to 'boost the immune system' (56%) and to "give a feeling of control with respect to their treatment" (56%). CAM therapy was used concurrently with conventional treatment in 88% of cases, however, 12% of patients felt that CAM could replace their conventional therapy. Psychological evaluation suggests CAM users perceived their risk of dying of breast cancer was similar to that of the non-Cam group (33% vs. 35%), however the CAM group had less severe anxiety and depression.
Conclusion
The motivation, objectives and benefits of CAM therapy in a selected population of women with LABC are similar to those reported for women diagnosed with early stage breast cancer. CAM users display less anxiety and depression and are less likely to believe they will die of their breast cancer. However the actual benefit to overall and disease free survival has yet to be demonstrated, as well as the possible interactions with conventional therapy. Consequently more research is needed in this ever-growing field.

Abstract
Objectives
Two of the most pressing public health challenges in the United States are treating human immunodeficiency virus (HIV) infection and illegal substance use. High rates of complementary and alternative medicine (CAM) use have been reported by individuals who suffer from both of these diseases. The goal of this study was to examine the relationship between CAM use and illegal substance use in a cohort of women with HIV or at risk for HIV disease. Based on previous research, it was hypothesized that CAM use may decrease substance use.
Design
This was a longitudinal cohort study.
Subjects
The subjects comprised Women in the Women's Interagency HIV Study.
Outcome measures
The role of CAM use in illegal substance use was examined. Due to the hierarchical structure of the dataset, logistic regression analysis adjusting for repeated measurements (generalized estimating equation model) was carried out to assess associations of CAM use and illicit drug use.
Results
There were 2176 women included in the analysis. After excluding for marijuana use, CAM use was associated with less drug use (odds ratio 0.82; 95% confidence interval: 0.73, 0.90).
Conclusions
The results supported our hypothesis that CAM users are more health conscious and thus less likely to use illicit drugs. Future studies should target both specific drugs and CAM modalities to help finalize this association.

Objective
Treatment with highly active antiretroviral therapy (HAART) reduces overall perinatal HIV-1 related mortality. The impact of timing of HAART initiation on reduction of morbidity is not well-defined. We evaluated the association of timing of HAART initiation on progression to moderate or severe disease.
Methods
Retrospective, population-based study of 196 perinatally HIV-infected children followed from birth in northern California from 1988 to 2009.
Results
Of 196 children, 58% received HAART and were followed for a median of 6.2 years after HAART initiation. HAART use was associated with improved survival to age 5 years: 50% no HAART vs. 88% HAART, p<0.0001. However, the advantage of initial HAART over mono or dual therapy transitioning to HAART was small and not statistically significant (p=0.23). Starting HAART before the development of moderate or severe disease delayed the median age of diagnosis of moderate disease from 0.4 years (IQR [0.3–0.8]) without HAART to 3.0 years ([IQR 1.9–5.8], p<.0001) with HAART. HAART initiation after progression to moderate or severe disease was associated with decreased progression to severe disease or death, respectively (moderate to severe: 8% (3/36) HAART vs. 84% (70/83) no HAART, p<0.0001; severe to death: 9% (6/68) HAART vs. 73% (49/67) no HAART, p<0.0001).
Conclusion
In perinatal HIV infection, HAART is associated with delayed progression and reduced mortality regardless of disease severity at HAART initiation. This finding reinforces U.S. guidelines regarding HAART initiation at>1 year of age if children present with most clinical category B diagnoses, regardless of CD4 measurements or plasma HIV RNA level.

Abstract
Objectives
The use of complementary and alternative medicine (CAM), a group of health care practices and products that are not considered part of conventional medicine, has increased in recent years, particularly among individuals with human immune deficiency virus (HIV). Assessing the prevalence and predictors of CAM use among HIV-positive populations is important because some CAM therapies may adversely affect the efficacy of conventional HIV medications. Unfortunately, CAM use is not comprehensively or systematically assessed among HIV-positive populations. Therefore, the aim of the present study was to evaluate the quality of the instruments employed in observational studies assessing CAM use among HIV-positive populations by examining the degree to which these studies (1) evaluated the psychometric properties of their CAM instruments and (2) assessed the multidimensional nature of CAM use.
Design
A systematic review of studies was undertaken and specific review criteria were used to guide the inclusion of studies. Specifically, articles were included that were published in English and in a peer-reviewed journal between 1997 and 2007, recruited HIV-positive study participants, and assessed CAM use. Thirty-two (32) studies met these inclusion criteria.
Results
Results suggest that CAM assessment among HIV-positive populations continues to be problematic. For example, approximately 20% of the studies assessed the reliability and 3% assessed the validity of the CAM instrument employed.
Conclusions
CAM assessment—regardless of the specific study population—is a complex and challenging task. However, CAM instruments will not become more refined over time in the absence of rigorous psychometric evaluation. Future research must assess reliability and validity and report these data in a clear and nuanced manner.

Objective
This study assessed the use of complementary and alternative medicine (CAM) therapies in patients with early systemic sclerosis (scleroderma, SSc).
Methods
At the annual visit, SSc patients enrolled in the Genetics versus Environment in Scleroderma Outcomes Study (GENISOS) were queried about their use of CAM therapies and intended symptom target, including herbal or nutriceutical therapy, acupuncture, transcutaneous electrical neural stimulation (TENS) and mind-body therapy (relaxation, meditative, imagery). The CAM user SSc patients were compared to matched non-CAM users over two years for database results of demographic, clinical and health-related quality of life SF-36 questionnaires by analysis of covariance.
Results
25% of the university GENISOS group were CAM users: age: 54 years; female: 89%; diffuse cutaneous involvement: 47%; total skin score: 13.5; Medsger severity index: 5.8. Over 70% used ≥1 CAM therapies for over 1 year, independent of health insurance. Symptoms targeted included arthritis/arthralgia, pain, GI dysmotility and fatigue. CAM users had significantly higher mean mental component summary (MCS) scores on SF-36 at Baseline and Year 2, (49 and 49.9), compared to non-CAM users (42 and 40.2, respectively, p<0.01). At Year 2, the CAM user group had significantly higher scores of SF-36 domains physical component score, role-physical, bodily pain and vitality, whereas scores declined in the non-CAM user group.
Conclusion
In SSc, 70% of those in the CAM user group reported a long-term commitment to CAM therapies. Higher perceived mental functioning in CAM users might reflect more self-motivation to manage symptoms and subsequently, promote practices that result in higher perceived physical functioning.

To determine predictors of complementary and alternative medicine (CAM) use, we used a cohort of 1,445 non-institutionalized Mexican Americans aged 65 and older from the first wave (1993–1994) of the Hispanic Established Population for the Epidemiologic Study of the Elderly, followed until 2000–2001. The main outcome was use of any CAM (herbal medicine, chiropractic, acupuncture, massage therapy, relaxation techniques or spiritual healing) in the past 12 months and was assessed at 7 years of follow-up. Potential predictors of CAM use at baseline included sociodemographics, acculturation factors, and medical conditions. The overall rate of CAM use among older Mexican Americans was 31.6%. Independent predictors of higher CAM use were female gender, being on Medicaid, frequent church attendance and higher number of medical conditions. In contrast, subjects who were born in US and spoke either Spanish or English at interview had lower CAM use compared with subjects who were born in Mexico.

We surveyed the attitudes of Japanese medical doctors toward complementary and alternative medicine (CAM) in 1999. It is supposed that the situation concerning CAM has been changing recently. The aim of the present study is to survey the attitude of doctors toward CAM again, and to examine changes in attitude over the last 6 years. The attitudes of medical doctors belonging to the Kyoto Medical Association toward CAM were surveyed by a structured, self-administered questionnaire in 1999 and 2005. The results showed that the doctors familiar with the term “CAM”, practicing CAM therapies, and attending meetings or training courses related with CAM, increased significantly from 1999 to 2005. The doctors who possessed knowledge of CAM also increased significantly from 1999 to 2005. Almost all doctors believed in the effectiveness of Kampo (Japanese traditional herbal medicine) and acupuncture. The number of doctors who believed in the effectiveness of aromatherapy and ayurveda increased significantly in 2005, compared with 1999. In the near future, 58% of doctors desired to practice CAM therapies. In conclusion, the numbers of doctors who practice CAM therapies, possess CAM knowledge and desire to practice such therapies have increased over the last 6 years in Japan.

Background
We previously reported an increased risk of all-cause and AIDS mortality among HIV-infected women with albuminuria (proteinuria or microalbuminuria) enrolled in the Women’s Interagency HIV Study (WIHS) prior to the introduction of highly active antiretroviral therapy (HAART).
Methods
The current analysis includes 1,073 WIHS participants who subsequently initiated HAART. Urinalysis for proteinuria and semi-quantitative testing for microalbuminuria from two consecutive study visits prior to HAART initiation were categorized as follows: confirmed proteinuria (both specimens positive for protein), confirmed microalbuminuria (both specimens positive with at least one microalbuminuria), unconfirmed albuminuria (one specimen positive for proteinuria or microalbuminuria), or negative (both specimens negative). Time from HAART initiation to death was modeled using proportional hazards analysis.
Results
Compared to the reference group of women with two negative specimens, the hazard ratio (HR) for all-cause mortality was significantly elevated for women with confirmed microalbuminuria (HR 1.9; 95% CI 1.2–2.9). Confirmed microalbuminuria was also independently associated with AIDS death (HR 2.3; 95% CI 1.3–4.3), while women with confirmed proteinuria were at increased risk for non-AIDS death (HR 2.4; 95% CI 1.2–4.6).
Conclusions
In women initiating HAART, pre-existing microalbuminuria independently predicted increased AIDS mortality, while pre-existing proteinuria predicted increased risk of non-AIDS death. Urine testing may identify HIV-infected individuals at increased risk for mortality even after the initiation of HAART. Future studies should consider whether these widely available tests can identify individuals who would benefit from more aggressive management of HIV infection and comorbid conditions associated with mortality in this population.

Abstract
Previous studies have shown that use of complementary and alternative medicine (CAM) is prevalent among HIV-infected persons, but have focused primarily on men who have sex with men. To determine factors associated with CAM use in an inner city population, individuals (n = 93) recruited from two established cohort studies were interviewed between October and November 2004. The interview assessed the use of dietary supplements and other CAM therapies, reasons for CAM use, and use of prescription medications. Study participants were 52% male and 47% HIV infected. Median age was 50 years, and 60% reported illicit drug use ever. CAM use during the prior 6 months was reported by 94%, with 48% reporting daily use of a dietary supplement. Vitamin C, vitamin E, and soy were used more often by HIV-infected than uninfected persons (p < 0.05). Prevention of illness was the most common reason for dietary supplement use (27%). HIV-infected persons were more likely than uninfected persons (95% versus 67%) to report use of both dietary supplements and prescription medications within the past 6 months (p < 0.001). In multivariate analysis, HIV infection (odds ratio [OR] 3.1, CI 1.3, 7.7) was the only factor associated with daily dietary supplement use whereas gender, race/ethnicity, working in the last year, homelessness, and financial comfort were not associated. CAM use among persons with or at risk for HIV infection due to drug use or high-risk heterosexual behaviors is common, and is used almost exclusively as an adjunct and not an alternative to conventional health care.

Background
The benefits of highly active antiretroviral therapy (HAART) for the treatment of HIV infection are well documented, but concerns regarding access and adherence to HAART are growing. We evaluated virological responses to HAART among HIV-1 infected patients who were injection drug users (IDUs) in a population-based setting where HIV/AIDS care is delivered free of charge.
Methods
We evaluated previously untreated HIV-1 infected men and women who initiated HAART between Aug. 1, 1996, and July 31, 2000, and who were followed until Mar. 31, 2002, in a province-wide HIV treatment program. We used Kaplan–Meier methods and Cox proportional hazards regression in our evaluation of time to suppression (i.e., less than 500 copies/mL) and rebound (i.e., 500 copies/mL or more) of plasma HIV-1 RNA, with patients stratified according to whether or not they had a history of injection drug use.
Results
Overall, 1422 patients initiated HAART during the study period, of whom 359 (25.2%) were IDUs. In Kaplan–Meier analyses, the cumulative suppression rate at 12 months after initiation of HAART was 70.8% for non-IDUs and 51.4% for IDUs (p < 0.001) (these values include people who achieved suppression before 12 months but who might not have been followed for the full 12-month period). Among patients who achieved suppression of plasma HIV-1 RNA, the cumulative rebound rate at 12 months after initial suppression was 23.8% for non-IDUs and 34.7% for IDUs (p < 0.001). However, after adjustment for adherence and other covariates, the rates of HIV-1 RNA suppression (adjusted relative hazard 0.9, 95% confidence interval [CI] 0.7–1.0) and HIV-1 RNA rebound (adjusted relative hazard 1.3, 95% CI 1.0–1.6) were similar between non-IDUs and IDUs. Differences between non-IDUs and IDUs were even less pronounced in subanalyses that considered only therapy-adherent patients (p > 0.1).
Interpretation
Non-IDUs and IDUs had similar rates of HIV-1 RNA suppression and rebound after the initiation of HAART, once lower levels of adherence were taken into account. Nevertheless, the lower virological response rates among IDUs suggest that, unless interventions are undertaken to improve adherence, these patients may experience elevated rates of disease progression and use of medical services in our setting.
