The current data on the influence of prior TST on IGRAs show inconsistent results.

METHODS: Sixteen non-bacille Calmette-Guerin immunised medical students with no history of TB exposure and minimal risk of exposure to TB during the study period were tested simultaneously with a TST and QFT-GIT. The QFT-GIT assay was repeated 6 and 10 weeks later.

RESULTS: At baseline, all TST and QFT-GIT results were

negative and remained negative 6 and 10 weeks after the TST.

CONCLUSION: These data show that negative QFT-GIT results are reproducible and suggest that a TST does not result in conversion of subsequent QFT-GIT assays in the absence of concomitant TB exposure. Therefore, PFTα cost a positive QFT-GIT should not be attributed to boosting induced by a previous TST.”
“Background: The effects of the various dialysis modalities 4EGI-1 concentration on patient survival are different, especially for diabetic patients. Hemodialysis (HD) and peritoneal dialysis (PD) are the predominant renal replacement modalities. This study analyzes modality-related mortality in long-term dialysis patients.

Methods: This prospective cohort study was conducted between May 1991 and October 2005. Incident patients that had initiated dialysis

and had been on dialysis for more than 3 months were enrolled. All cause, infection related, and cardiovascular disease-related mortalities were used as end points. Patient survival was analyzed by the Cox proportional hazards model after adjusting for age, sex, diabetes, comorbidity, and time-averaged values of laboratory data to control influential covariates.

Results: In total, 1347 patients (258 on PD and 1089 on HD) were enrolled. Adjusted all cause, infection related, and cardiovascular disease-related

mortality did not differ significantly between HD and PD patients. In diabetic patients, adjusted all-cause [HD vs PD: hazard ratio (HR) 0.717, 95% confidence interval (CI) 0.400-1.282] and infection-related mortality (HD vs PD: HR find more 1.341, 95% CI 0.453-3.969) did not differ significantly between patients on HD and patients on PD. However, adjusted cardiovascular disease-related mortality increased significantly in diabetic PD patients (HD vs PD: HR 0.375, 95% CI 0.154-0.913). For nondiabetic patients, adjusted all cause, infection related, and cardiovascular disease-related mortality did not differ significantly between HD and PD patients.

Conclusions: Dialysis modality had no significant impact on all-cause or infection-related mortality. More studies are needed to clarify the putative difference in cardiovascular mortality risk between diabetic patients on PD and diabetic patients on HD.”
