Abstract
Background: A single self-rated health (SRH) assessment is associated with clinical outcome and mortality, but the biological process linking SRH with immune status remains incompletely understood.
Objectives: To examine the association between SRH and inflammation in apparently healthy individuals.
Methods: Our analysis included 13,773 apparently healthy individuals attending the Tel Aviv Sourasky Medical Center for periodic health examinations. Estimated marginal means of the inflammation-sensitive biomarkers [i.e., highly sensitive C-reactive protein (hs-CRP) and fibrinogen] for the different SRH groups were calculated and adjusted for multiple potential confounders including risk factors, health behavior, socioeconomic status, and coexistent depression.
Results: The group with the lowest SRH had a significantly higher atherothrombotic profile and significantly higher concentrations of all inflammation-sensitive biomarkers in both genders. Hs-CRP was found to differ significantly between SRH groups in both genders even after gradual adjustments for all potential confounders. Fibrinogen differs significantly according to SRH in males only, with low absolute value differences.
Conclusions: A valid association exists for apparently healthy individuals of both genders between inflammation-sensitive biomarker levels and SRH categories, especially when comparing levels of hs-CRP. Our findings underscore the importance of assessing SRH and treating it like other markers of poor health.

Abstract
Background: The mass influx of immigrants from tuberculosis-endemic countries into Israel was followed by a considerable increase in the incidence of tuberculosis (TB). All contacts of active TB patients are obliged to be screened by tuberculin skin tests (TST) and, if found positive, prophylactic treatment is considered.
Objectives: To assess the utility of interferon-gamma (IFNγ)-release assay with a prolonged follow-up in preventing unnecessary anti-TB therapy in individuals with suspected false positive results.
Methods: Between 2008 and 2012 the QuantiFERON TB gold-in-tube test (QFT-G) was performed in 278 sequential individuals who were mostly TST-positive and/or were in contact with an active TB patient. In all, whole blood was examined by the IFNγ-release assay. We correlated the TST diameter with the QFT-G assay and followed those patients with a negative assay.
Results: The QFT-G test was positive in only 72 (42%) of all 171 TST-positive individuals. There was no correlation between the diameter of TST and QFT-G positivity. Follow-up over 5 years was available in 128 (62%) of all QFT-G-negative individuals. All remained well and none developed active TB.
Conclusions: A negative QFT-G test may obviate the need for anti-TB therapy in more than half of those with a positive TST.
