IMPORTANCE Antiretroviral therapy (ART) has improved life expectancy for individuals with HIV infection, but recent data comparing life span and comorbidity-free years by HIV status are lacking.

Capecitabine, an oral prodrug of 5-fluorouracil, inhibits DNA synthesis and has received FDA approval for treatment of metastatic colorectal and breast cancers. Hand-foot syndrome (HFS) is a serious dose-limiting toxicity and the most frequently reported side effect of capecitabine. Because of the lack of knowledge about the causative mechanism of HFS, scarce information is available for effective treatment or prevention. Data are based on published literatures and reports available from the HFS development program database. The purpose of this Review is to provide information regarding definition, clinical manifestation, and the possible mechanisms of HFS induced by capecitabine. Ethnic variations in the clinical presentation of HFS warrant further attention. Several physiological and pharmacological mechanisms have been investigated, such as cyclooxygenase (COX) inflammatory-type reaction, accumulation of capecitabine metabolites, and enzymes and transporters involved in the metabolism and absorption. Although current studies describe the possible mechanisms of HFS induced by capecitabine, much remains to be determined. It appears from this scientific evidence that additional study is needed to determine the effect of skin-mediated metabolism in the possible mechanism of HFS induced by capecitabine.

Candidiasis in HIV/AIDS patients continues to be a public health problem. Effective antifungal therapies are few in number and have inherent problems such as selecting for drug-resistant strains of Candida species. To evaluate the state of Candida colonization of the oral and vaginal mucosa, we recruited 80 women, both HIVinfected and HIV-uninfected, from the Women's Interagency HIV Study (WIHS). Diet diaries were collected by participants to examine the role of diet on fungal growth. Baseline studies were initially done in participants that followed the colonization of both mucosal sites over 0-90 days. The most common Candida species from both groups of patients were C. albicans and C. glabrata. Among the HIV-infected cohort, the percentage of participants who were positive for Candida spp. was higher than in the HIV-uninfected control group. Furthermore, the frequency of colonization (1 episode versus > 1 episode) was also increased in the HIV-infected cohort. These data indicate that Candida species remain an important component of the microbial community in both populations.

Background Candidiasis in HIV/AIDS patients continues to be a public health problem. Antifungal therapies are not always effective and may result in complications, such as the development of drug-resistant strains of Candida species. Objectives This study evaluated the impact of probiotic consumption on Candida colonization of the oral and vaginal mucosa. Patients/Methods A pilot study was conducted in 24 women (17 HIV-infected, 7 HIV-uninfected) from the Women's Interagency HIV Study. The women underwent a 60-day initiation period with no probiotic consumption, followed by two 15-day consumption periods, with a different probiotic yogurt (DanActive™ or YoPlus™ yogurt) during each interval. There was a 30-day washout period between the two yogurt consumption periods. Oral and vaginal culture swabs were collected on days 0, 60, 74, and 120. Candida was detected by inoculating each swab in both Sabouraud's dextrose agar with or without chloramphenicol and CHROMagar. Results Less fungal colonization among women was observed when the women consumed probiotic yogurts (54 % of the women had vaginal fungal colonization during the non-probiotic yogurt consumption period, 29 % during the DanActive™ period, and 38 % during YoPlus™ yogurt consumption period), and HIV-infected women had significantly lower vaginal fungal colonization after they consumed DanActive™ yogurt compared to the nonintervention periods (54 vs 29 %, p = 0.03). Conclusions These data are promising, but as expected in a small pilot study, there were some significant changes but also some areas where colonization was not changed. This type of conflicting data is supportive of the need for a larger trial to further elucidate the role of probiotic yogurts in fungal growth in HIV-infected women.
