Polysaccharides isolated from Echinacea purpurea herba cell cultures to counteract undesired effects of chemotherapy--a pilot study.
In an open prospective study with matched historical controls we aimed to evaluate whether a polysaccharide fraction isolated from the herb Echinacea purpurea could counteract the undesired effects of chemotherapy. Fifteen patients with advanced gastric cancer undergoing palliative chemotherapy with etoposide, leucovorin and 5-fluorouracil (ELF) received for 10 days (beginning 3 days before chemotherapy) daily i.v. injections of 2 mg of a polysaccharide fraction isolated from Echinacea purpurea herb cell cultures (EPS-EPO VIIa). The median number of leukocytes 14-16 days after chemotherapy was 3630/microL (range 1470-5770) in the patients receiving EPS-EPO VIIa compared with 2370/microL (870-3950) in the patients of the historical control group (p = 0.015). EPS-EPO VIIa had no clinically relevant effects on phagocytic activity of granulocytes or on lymphocyte subpopulations. Sixty-eight adverse events including two deaths were observed, most likely due to chemotherapy and the general condition of the patients. However, an association with the test intervention cannot be ruled out completely. The results of this pilot study suggest that EPS-EPO VIIa might be effective in reducing chemotherapy-induced leukopenia. The efficacy and safety should be investigated in further studies.

[Difficulties in the evaluation of depressive symptoms in patients with dementia].
Depressive symptoms are often found in dementia (up to 86 %). Therefore, adequate treatment is necessary. Depressive symptoms appear significantly more often in vascular dementia than in dementia in Alzheimer's disease, but severity and profile of depressive symptomatology are independent of the etiology of dementia. The aim of this review is to help clinicians to select appropriate psychometric instruments to identify and measure depressive symptomatology in dementia. Frequently used scales are described, e.g. the Dementia Mood Assessment Scale and the Cornell Scale for Depression in Dementia - specific scales developed for rating severity of depression in dementia - and the Geriatric Depression Screening Scale. Methodological problems and limitations of psychopathological assessment in dementia caused by restriction of self-report, information gathered by collateral sources, manifestations of age and interference of somatic symptoms are discussed.
