Black Women More Likely To Have Vitamin D Deficiency, Bacterial Vaginosis, Study Finds
Black women are nearly three times as likely as white women to have a vitamin D deficiency, which is linked with an increased risk of the vaginal infection bacterial vaginosis, according to a study published in the June issue of the Journal of Nutrition, the New York Times reports. Black women likely have lower levels of vitamin D because the higher amount of pigment in their skin prevents the body from absorbing the vitamin.For the study, researchers led by Lisa Bodnar, an assistant professor of epidemiology at the University of Pittsburgh, examined 209 white pregnant women and 260 black pregnant women at a Pittsburgh clinic. More than half of the women had low levels of vitamin D, the study found. Women whose vitamin D levels were 50 nanomoles or less had a 26% increased risk of BV, while women whose vitamin levels were less than 20 nanomoles had a 65% increased risk of the infection. About 52% of black women had the infection, compared with 27% of white women, the study found (Bakalar, New York Times, 5/26). The study found that 93% of women with BV had low vitamin D levels and that BV prevalence decreased as vitamin levels increased.In addition, although black women were more likely to have BV, white women who had low levels of vitamin D were as likely to have the infection as black women. Poor diets and obesity also contributed to a vitamin deficiency. Bodnar noted that black women are less likely than white women to meet dietary recommendations for vitamin D. Bodnar recommended that women discuss their level of vitamin D with their physicians and that pregnant women take a prenatal vitamin, which typically includes vitamin D.According to the Pittsburgh Post-Gazette, Bodnar"s research team has received NIH funding to conduct a study of whether vitamin D deficiency in women increases the risk of poor birth outcomes and whether high infant mortality among blacks can be attributed to factors such as obesity (Templeton, Pittsburgh Post-Gazette, 5/23).

Yaupon Therapeutics Completes Patient Enrollment For Pivotal Phase 2 Study Of Clearazide For Treatment Of Cutaneous T-cell Lymphoma
Yaupon Therapeutics, a privately held specialty pharmaceutical company, has announced it has completed enrollment for a pivotal Phase 2 clinical trial for Clearazide for the treatment of early-stage cutaneous T-cell lymphoma (CTCL - stages 1-2a). The study, which is being conducted under a Special Protocol Assessment (SPA) with the FDA, has enrolled 260 patients in 13 of the top cancer centers in the US. Yaupon expects the last patient to complete treatment in the study by June of 2010 and, assuming positive results, will file its NDA shortly thereafter.

Ginseng -- Nature's Anti-Inflammatory?

Laboratory experiments have demonstrated the immunological effects of ginseng. Researchers writing in BioMed Central"s open access Journal of Translational Medicine have shown that the herb, much used in traditional Chinese and other Asian medicine, does have anti-inflammatory effects. Allan Lau led a team of researchers from the University of Hong Kong who identified seven ginseng constituents, ginsenosides, which showed immune-suppressive effects. He said, "The anti-inflammatory role of ginseng may be due to the combined effects of these ginsenosides, targeting different levels of immunological activity, and so contributing to the diverse actions of ginseng in humans". The scientists treated human immune cells with different extracts of ginseng. They found that of the nine ginsenosides they identified, seven could selectively inhibit expression of the inflammatory gene CXCL-10. Lau concludes, "Further studies will be needed to examine the potential beneficial effects of ginsenosides in the management of acute and chronic inflammatory diseases in humans". Uniquely, the researchers were able to holistically test the ginseng extract"s immune effects by using sophisticated purification technologies to identify individual constituents and define their bioactivity using genomics and bioactivity assays. After that, they reconstituted them back into a whole extract with definable individual ginsenosides for re-confirmation of effects. This potentially opens up a vigorous methodology to study medicinal herbs with state-of-the-art technologies.
