Soluble toll-like receptor 2 is a biomarker for sepsis in critically ill patients with multi-organ failure within 12Â h of ICU admission
Soluble TLR2 levels are elevated in infective and inflammatory conditions, but its
diagnostic value with sepsis-induced multi-organ failure has not been evaluated. 37
patients with a diagnosis of severe sepsis/septic shock (sepsis) and 27 patients with
organ failure without infection (SIRS) were studied. Median (IQR) plasma sTLR2 levels
were 2.7 ng/ml (1.4–6.1) in sepsis and 0.6 ng/ml (0.4–0.9) in SIRS p < 0.001. sTLR2
showed good diagnostic value for sepsis at cut-off of 1.0 ng/ml, AUC:0.959. We
report the ability of sTLR2 levels to discriminate between sepsis and SIRS within 12 h
of ICU admission in patients with multi-organ failure
Evidence of prokineticin dysregulation in fallopian tube from women with ectopic pregnancy
OBJECTIVE: To demonstrate expression and regulation of prokineticins (PROKs) and their receptors (PROKRs) in Fallopian tube (FT) from non-pregnant women and women with ectopic pregnancy (EP). DESIGN: Tissue analysis. SETTING: Large UK teaching hospital PATIENTS: Women undergoing hysterectomy for benign gynecological conditions (n=15) and surgery for EP (n=16). INTERVENTIONS: Quantitative RT-PCR and immunohistochemistry were used to determine FT PROK/PROKR mRNA expression and protein localization, respectively. PROK/PROKR levels were measured in tubal explant cultures stimulated with estrogen and progestogen. MAIN OUTCOME MEASURES: Differential expression of PROK and PROKR. RESULTS: FT PROK2 and PROKR1 mRNA levels were upregulated during the progesterone-dominant mid-luteal phase of the menstrual cycle. Increased PROKR1 expression was observed in tubal explant cultures treated with medroxyprogesterone acetate. PROK and PROKR proteins were localized to the epithelium and smooth muscle layers of the FT. PROKR1 and PROKR2 mRNA levels were lower in FT from women with EP compared to non-pregnant FT from the mid-luteal phase. CONCLUSION: These data suggest a potential role for PROKs in FT function. PROKs are known to affect smooth muscle contraction in the gut. Dysregulated PROK expression in FT could affect FT smooth muscle contractility and embryo-tubal transport, providing a potential cause for EP
