Effect of a yoghurt drink containing Lactobacillus strains on bacterial vaginosis in women - a double-blind, randomised, controlled clinical pilot trial.

Bacterial vaginosis (BV) is characterised by a depletion of lactobacilli in favour of an overgrowth of anaerobic bacteria. It is associated with increased risk for urogenital infections and abortion. In this study we assessed the effect of a yoghurt drink containing Lactobacillus strains on BV.

Wilms' tumour gene (wt1) expression at diagnosis has no prognostic relevance in childhood acute lymphoblastic leukaemia treated by an intensive chemotherapy protocol.

Expression of the Wilms' tumour gene (wt1) has been demonstrated in a large proportion of human acute leukaemias and is thought to play a role in leukaemogenesis. Recent observations in adult patients with acute leukaemia suggest that wt1 gene expression is a poor prognostic factor. In childhood acute leukaemia, the clinical role of wt1 gene expression has not been established.

Detection of the WT1 transcript by RT-PCR in complete remission has no prognostic relevance in de novo acute myeloid leukemia.

The WT1 gene is expressed in 73-100% of patients with acute myelogenous leukemia (AML) and is thought to play a role in maintaining the viability of leukemic cells. WT1 has been proposed as a marker for minimal residual disease in leukemia. We obtained serial blood or bone marrow samples from patients with de novo AML at diagnosis, during therapy, and up to 95 months after diagnosis and analyzed for WT1 gene expression by RT-PCR to determine whether gene expression was predictive of relapse.

Prognostic significance of WT1 gene expression at diagnosis in adult de novo acute myeloid leukemia.

We examined the presence of WT1-specific mRNA in bone marrow samples of 125 patients with de novo acute myeloid leukemia at diagnosis by two-step RT-PCR. The sensitivity of the assay was 1:100 (first step) and 1:10000 (second step), respectively. WT1-specific mRNA was detected in 73% of patients.
