Adetifa I, Kendall L, Donkor S, Lugos M, Hammond A, Owiafe P, et al.
Am J Trop Med Hyg . 2017 Jul; 97(2):429-432. PMID: 28722570
Tobacco use is a major risk factor for tuberculosis (TB). Secondhand smoke (SHS) is also a risk factor for TB and to a lesser extent, infection without disease. We investigated...

Adetifa I, Ota M, Jeffries D, Lugos M, Hammond A, Battersby N, et al.
Am J Respir Crit Care Med . 2012 Dec; 187(4):439-45. PMID: 23220919
Rationale: Biomarkers that can be used to evaluate new interventions against latent tuberculosis infection (LTBI) and predict reactivation TB disease are urgently required. Objectives: To evaluate ESAT-6 and CFP-10 (EC)...

Maiga M, Siddiqui S, Diallo S, Diarra B, Traore B, Shea Y, et al.
PLoS One . 2012 May; 7(5):e36902. PMID: 22615839
Background: Nontuberculous mycobacterial (NTM) infections cause morbidity worldwide. They are difficult to diagnose in resource-limited regions, and most patients receive empiric treatment for tuberculosis (TB). Our objective here is to...

Adetifa I, Ota M, Walther B, Hammond A, Lugos M, Jeffries D, et al.
PLoS One . 2010 Sep; 5(9). PMID: 20824136
Background: Qualitative and quantitative changes in IGRA response offer promise as biomarkers to monitor Tuberculosis (TB) drug therapy, and for the comparison of new interventions. We studied the decay kinetics...

Brookes R, Hill P, Owiafe P, Ibanga H, Jeffries D, Donkor S, et al.
PLoS One . 2008 Aug; 3(8):e2921. PMID: 18698342
Background: Vaccination with a recombinant modified vaccinia Ankara expressing antigen 85A from Mycobacterium tuberculosis, MVA85A, induces high levels of cellular immune responses in UK volunteers. We assessed the safety and...

Hammond A, McConkey S, Hill P, Crozier S, Klein M, Adegbola R, et al.
J Infect Dis . 2008 Jan; 197(2):295-9. PMID: 18194089
Antimycobacterial T cell reactivity at different stages of HIV infection was investigated. Subjects were screened with purified protein derivative (PPD), early secreted antigenic target (ESAT)-6, and culture filtrate protein (CFP)-10...

Fox A, Jeffries D, Hill P, Hammond A, Lugos M, Jackson-Sillah D, et al.
Trans R Soc Trop Med Hyg . 2007 Apr; 101(7):691-8. PMID: 17434194
Commercial tests measuring IFN-gamma responses to ESAT-6 and CFP-10 are available for diagnosing Mycobacterium tuberculosis infection. Measures that minimize cost and complexity will facilitate their application in less-developed countries. We...

Hill P, Jackson-Sillah D, Fox A, Franken K, Lugos M, Jeffries D, et al.
J Clin Microbiol . 2005 May; 43(5):2070-4. PMID: 15872224
Overlapping peptides of Mycobacterium tuberculosis antigens ESAT-6 and CFP-10 offer increased specificity over the purified protein derivative skin test when they were used in an ex vivo enzyme-linked immunospot (ELISPOT)...
9.
Hill P, Fox A, Jeffries D, Jackson-Sillah D, Lugos M, Owiafe P, et al.
Clin Infect Dis . 2005 Jan; 40(2):273-8. PMID: 15655747
Background: Currently, reliable efficacy markers for assessment of new interventions against tuberculosis (TB) are limited to disease and death. More precise measurement of the human immune response to Mycobacterium tuberculosis...

Hill P, Brookes R, Fox A, Fielding K, Jeffries D, Jackson-Sillah D, et al.
Clin Infect Dis . 2004 Mar; 38(7):966-73. PMID: 15034828
The purified protein derivative (PPD) skin test for Mycobacterium tuberculosis infection lacks specificity. We assessed 2 more specific M. tuberculosis antigens (ESAT-6 and CFP-10) by enzyme-linked immunospot assay (ELISPOT) compared...
