the present investigation included new participants from cohorts 1 (143 subjects) and 2 (80 subjects) in addition to the original participants from cohort 3 (61 subjects) who were withdrawn from the study and did not undergo repeat testing. of new participants, 38% were qft indeterminate at baseline, 26% had a baseline tst indeterminate result, and 35% had both a baseline tst and qft indeterminate result. repeat testing occurred between 8 and 18 weeks after baseline testing. in spite of repeat testing, approximately 10% of subjects remained indeterminate (figure s2) for the qft and tst.
during the period of the study, the quantiferon-tb gold in-tube (qft-git) assay (cellestis, victoria, australia) was replaced by the qft-gold. although not directly comparable to the qft-git results reported here, the new assay has proven to be sensitive in use for serial testing in an african cohort ( 18 20 ).
the qft test results were closely correlated with tst results in both the initial evaluation (r = 0.58; 95% confidence interval [ci], 0.46 to 0.68; p < 0.001) and the first follow-up (r = 0.65; 95% ci, 0.53 to 0.74; p < 0.001). eighteen percent of tst converters and 17% of nontuberculous converter had ifn- values greater than 0.7 iu/ml, suggesting that this value should not be used as a cutoff for response to mtb infection. a longitudinal analysis of these tst converters showed that 10 of 25 (40%) experienced disease progression (6 case-patients, 3 infection-progression, and 1 death-case) during the 2 years of the study (p<0.0001). among the converters, 16 of 25 (64%) had mtb-specific ifn- values greater than 0.7 iu/ml at the time of diagnosis of active tb. when results were split by mtb status (positive vs negative) there was no significant difference in progression-free survival for converter (p = 0.06) and nontuberculous converter (p = 0.18). among the 50 converters included in this study, 48 (96%) had a negative (mtb-specific ifn->0.2 iu/ml) qft-git result on their initial test. sixty-six percent of these 48 converters had mtb-specific ifn->0.2 iu/ml on their first follow-up test. among the 12 converters without a mtb-specific ifn- value at initial testing, none had a subsequent positive (mtb-specific ifn->0.2 iu/ml) qft-git result, nor did any of the 24 converters with a negative (mtb-specific ifn-<0.2 iu/ml) qft-git result on their initial test have a subsequent positive result on follow-up testing (mtb-specific ifn->0.2 iu/ml).

the simple steps that can save lives from the american academy of pediatrics’ website provides simple and easy to follow tips for expecting and new moms. these step-by-step can save you from potential harm and ensure that your baby is as safe as possible. i’m happy to see this website covered on this week’s word!
this is a longitudinal trial which evaluated the safety of an 8-aminoquinoline drug, moxifloxacin, in adolescent and adult tuberculin-positive individuals with and without prior tb disease. we report on the 1-month post-tb therapy safety data from our trial, including changes in qft and tst results and the frequency of adverse events. a recent meta-analysis suggests that outpatients treated for active tb usually have negative tst results. however, new tst conversions and positive qft results are common, especially in adults, because of mtb persistence at sites not typically affected by disease and in the setting of concomitant infection with nontuberculous mycobacteria. based on the negative tst results in this trial and preclinical data, we hypothesized that the 8-aminoquinoline drug, moxifloxacin, would be safe in subjects with latent tb, regardless of tst or qft status. contrary to this hypothesis, tst conversion was observed in 2 of 64 (3%) moxifloxacin-treated subjects, including 1 who was simultaneously coinfected with nontuberculous mycobacteria and had a latent tb diagnosis. the other subject had confirmed tb and had positive qft results, which remained stable after therapy. moxifloxacin also resulted in qft conversion in 4 of 63 (6%) moxifloxacin-treated subjects without tb disease. moxifloxacin therapy was discontinued in all 4 cases, but 3 of them continued to receive supervised antibiotic therapy. among subjects treated with moxifloxacin without tb disease, the number with positive tst results was not higher than in the placebo arm of our trial. adverse events, mainly gastrointestinal and eye disorders, were reported in 41 of 63 (65%) moxifloxacin-treated subjects and in 23 of 64 (36%) placebo-treated subjects. moxifloxacin-treated subjects had a similar frequency of serious adverse events as placebo-treated subjects, and 15 of 63 (24%) moxifloxacin-treated subjects and 9 of 64 (14%) placebo-treated subjects experienced adverse events that led to discontinuation of the treatment. allergic reactions to moxifloxacin and isoniazid were more frequently reported than either placebo- or amikacin-associated reactions. nevertheless, none of the subjects had a serious adverse event related to moxifloxacin. it appears that moxifloxacin cannot be recommended for treatment of latent tb in subjects with positive tst and/or qft results. whether qft can be used reliably to assess efficacy of antimycobacterial drugs in active tb disease will require evaluation in ongoing tb treatment trials (see appendix for an explanation of the qft assay).
