- 23 Background: Bi-weekly docetaxel (T) with prednisone improved progression free survival and overall survival when compared with the standard tri-weekly T as first-line treatment for advanced castration resistant prostate cancer (CRPC) (Lancet Oncol. 2013;14:117-124). We report here the quality of life (QoL) results of this prospective randomized trial. Methods: Three hundred and forty-six patients were randomly allocated centrally to receive intravenous therapy T of either 75 mg/m² d1 q3 wks (the triweekly arm) or 50 mg/m² d1 and d 14, q4 wks (the biweekly arm) (identifier NCT00255606). Prednisone (10 mg/d) was administered orally in both groups. The baseline patients characteristics were well balanced between the groups with respect to the performance status, mean age (69, range 45 to 87 vs. 68, range 46 to 85), and median serum prostate-specific antigen (PSA) content (109 µg/L, range 11 to 1,230 vs. 116 µg/L, range 12 to 1,870). Quality of life (QoL), the frequency and severity of symptoms including pain were assessed using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) version 4.0 questionnaire. Results: The baseline (QoL) of both treatment groups was compared to QoL after six months of the treatment within each treatment group and between groups. Changes in fatigue, symptoms of pain and nausea, and the overall performance status did not differ between the groups. There were statistically significant differences in overall quality of life values (p=0.010) and discomforting pain values (p=0.028) favoring the bi-weekly treatment arm. Conclusions: Bi-weekly T is better tolerated than the tri-weekly standard T. Following the results from the clinical outcome and the QoL outcome in the PROSTY trial we would recommend the use of bi-weekly docetaxel as first line treatment of CRPC Clinical trial information: NCT00255606.

- Pyelonephritis is one of the most common febrile diseases in children. If not treated appropriately, it causes irreversible renal damage and accounts for a large proportion of end stage renal failures(1). Renal scarring can occur in the absence of inflammatory cells, indicating that bacteria may have a direct signalling effect on renal cells(2). Intracellular calcium ([Ca2+](i)) oscillations can protect cells from the cytotoxic effects of prolonged increases in intracellular calcium(3,4). However, no pathophysiologically relevant protein that induces such oscillations has been identified. Here we show that infection by uropathogenic Escherichia coli induces a constant, low-frequency oscillatory [Ca2+](i) response in target primary rat renal epithelial cells induced by the secreted RTX (repeats-in-toxin) toxin alpha-haemolysin. The response depends on calcium influx through L-type calcium channels as well as from internal stores gated by inositol triphosphate. Internal calcium oscillations induced by alpha-haemolysin in a renal epithelial cell line stimulated production of cytokines interleukin (IL)-6 and IL-8. Our findings indicate a novel role for alpha-haemolysin in pyelonephritis: as an inducer of an oscillating second messenger response in target cells, which fine-tunes gene expression during the inflammatory response.
