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, selleck chemicals llc a positive QFT-GIT should not be attributed to boosting induced by a previous TST.”
“Background: The effects of the various dialysis modalities selleck products 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 EGFR tumor 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.”
