BACKGROUND The tuberculin skin test (TST) is used to test for latent tuberculosis (TB) infection and support the diagnosis of active TB. However, little is known about the relationship between the TST result and the clinical presentation of TB disease. METHODS We analyzed US TB surveillance data, 1993-2010, and used multinomial logistic regression to calculate the association between TST resu...

Non-HIV immunocompromised patients may develop immune reconstitution inflammatory syndrome (IRIS) as an abnormal response to invading microorganisms, such as Mycobacterium tuberculosis (MTB). IRIS consists in a sudden change in the dominant T-helper responses to inflammation, which is not balanced by anti-inflammatory response, playing a critical role in microbial pathogenesis. A patient with r...

The goal of vaccination to prevent tuberculosis disease (TB) is to offer long-term protection to the individual and the community. In addition, the success of any protective TB vaccine should include the ability to limit cavitary formation and disease progression. The current BCG vaccine protects against disseminated TB disease in children by promoting development of antigenic-specific response...

OBJECTIVE To compare the frequency of unfavorable outcome (death or default and treatment failure) between tuberculosis (TB)/HIV co-infected patients treated for TB after laboratory confirmation of the diagnosis and TB/HIV co-infected patients who were so treated without diagnostic confirmation. METHODS A retrospective cohort of TB/HIV co-infected patients who started TB treatment between Jul...

OBJECTIVE: Our aim was to describe the patient characteristics, clinical–epidemiological profile, and treatment outcome of childhood tuberculosis (TB). METHODS: A retrospective, descriptive study was undertaken of 1212 children aged 0 to 18 years admitted to Beijing Children’s Hospital for the treatment of TB from January 2002 to December 2010. Statistical significance of category variables was...

Objectives: 1) To study tuberculosis (TB) infection in a cohort of patients with systemic lupus erythematosus (SLE) and to compare its frequency and characteristics with that of others series. 2) To look for differential characteristic among SLE patients with and without TB. 3) To investigate if there was any relationship between TB’s most severe forms and higher doses of glucocorticoids (GC) o...

conclusions molecular epidemiology studies of infectious diseases have been useful when bacterial isolates have been clustered in a period of time and in different geographical regions with variable antibiotic resistance patterns. in spite of high geographical differences and different antibiotic resistant patterns, low genetic diversity among the studied tb isolates may refer to the low rate o...

BACKGROUND Changing epidemiology and diagnostic difficulties of paediatric tuberculosis (TB) are being increasingly reported. Our aim was to describe clinico-epidemiological profile and diagnostic procedures used for paediatric TB. METHODS A retrospective case-series analysis was carried out in a tertiary care teaching hospital of western Nepal. All pediatric TB (age 0-14 years) patients regi...

BACKGROUND With evolving evidence of association between tuberculosis (TB) and tobacco smoking, recommendations for the inclusion of tobacco cessation interventions in TB care are becoming increasingly important and more widely disseminated. Connecting TB and tobacco cessation interventions has been strongly advocated as this may yield better outcomes. However, no study has documented the impac...

OBJECTIVES 1) To study tuberculosis (TB) infection in a cohort of patients with systemic lupus erythematosus (SLE) and to compare its frequency and characteristics with that of others series. 2) To look for differential characteristic among SLE patients with and without TB. 3) To investigate if there was any relationship between TB's most severe forms and higher doses of glucocorticoids (GC) or...
