Background: Patients with a history of tuberculosis (TB) have a high probability of recurrence because long-term cure is not always maintained in successfully treated patients. The aim of this study was to identify the probability of TB recurrence and its predictive factors in a cohort of socially vulnerable patients who completed treatment in the TB referral center in Catalonia, which acts as the center for patients with social and health problems.
Methods: This retrospective open cohort study included all patients diagnosed with TB who were admitted and successfully treated in Serveis Clínics between 2000 and 2016 and who remained disease-free for a minimum of 1 year after treatment completion.
Background: To determine the prevalence of smoking and analyze associated factors in a cohort of patients diagnosed with tuberculosis (TB) in Spain between 2006 and 2013.
Methods: Multicenter, cross-sectional, descriptive, observational study using a national database of TB patients, using logistic regression to calculate odds ratios (OR) and confidence intervals (CI).
Results: We analyzed 5,846 cases (62 % men, mean age 39 years, 33 % foreigners).
Objectives: To determine predictive factors for changes in standard anti-tuberculosis chemotherapy at the time of diagnosis.
Methods: A prospective study was performed among tuberculosis (TB) patients treated at specialised centres during 2008-2009. Treatment outcome was monitored per standard guidelines.
Setting: Passive smoking-related respiratory disorders in children.
Objectives: To assess the effect of passive smoking on the development of active pulmonary tuberculosis (PTB) in children immediately following infection by Mycobacterium tuberculosis within the family.
Design: An unmatched case-control study in which 93 contacts who became cases (active PTB diagnosed) and 95 contacts who did not became cases (tuberculin-positive children without evidence of active disease) were included.
Setting: The association between smoking and pulmonary tuberculosis has not often been studied.
Objective: To assess the influence of cigarette smoking on the development of active pulmonary tuberculosis in young people who were close contacts of new cases of smear-positive pulmonary tuberculosis.
Design: A case-control study in which 46 'cases' (patients with active pulmonary tuberculosis: isolation of Mycobacterium tuberculosis or clinical and/or radiographic evidence of current pulmonary tuberculosis, with a positive tuberculin skin test) and 46 'controls' (persons with positive tuberculin reaction, negative bacteriological test and without clinical and/or radiological evidence of pulmonary tuberculosis) were included.
Background: The aim of this study was to know the efficacy of the BCG vaccination campaign of the newborns of Barcelona carried out during the period from 1966-1974.
Methods: To achieve this aim an epidemiologic investigation was undertaken by an observational analytical study of paired cases and controls. Two hundred and fifty randomly selected cases were studied between 1978-1988 from between 4-21 years of age during the study period.
Background: The aim of this study was to know whether the human reaction to the Mantoux test with 5 UT of PPD RT 23 is similar to that achieved with the same test but with 2 UT of the same substance.
Methods: A simultaneous double Mantoux test was used at doses of 2 UT and another of 5 UT of the same trade mark of tuberculin PPD RT 23 with Tween 80 in 2,575 individuals. The subjects were distributed into two different groups of different ages, taking into consideration the possible presence of BCG vaccination.
