In the current number of the Journal, Ci.ANCY et al. [1] have examined 29 specimens of sputum from patients before and during chemotherapy by direct smear, culture and guinea-pig inoculation with the aim of deciding whether there is any change in pathogenicity during the early weeks of chemotherapy. They found that the occurrence of tuberculosis in the guinea-pig was more closely associated wit...
Purpose: Smear scores and induration sizes resulting from the PPD (tuberculin purified protein derivative) test can serve as indicators of whether a patient suffering from tuberculosis shows smear conversion or not. Methods: Using microbiological methods smear and sputum tests, patients diagnosed as infected with Mycobacterium tuberculosis between 2002 and 2015 were included in this study. All ...
Background and purpose: Direct smear microscopy is the most common method of detecting tuberculosis with 70% sensitivity in best conditions, therefore, researches have always focused on improving the sensitivity of sputum smear. This study aimed at comparing the diagnostic value of sputum smear using light microscopy and fluorescence microscopy without sodium hypochlorite in patients with suspe...
Purpose: To study the factors influencing sputum smear conversion including Serum C-Reactive Protein (CRP) and its correlation with disease severity in tuberculosis patients. Method: Levels of Serum-CRP concentrations were determined in 60 patients with pulmonary tuberculosis, 30 healthy volunteers and patients in follow-up after completion of antitubercular treatment (DOTS therapy). Results: S...
background: there is growing evidence that diabetes mellitus (dm) is an important risk factor for tuberculosis (tb). a significant number of dm patients have poor glycemic control. this study was carried out to find the impact of poor glycemic control on newly diagnosed smear-positive pulmonary tuberculosis patients with type-2 diabetes mellitus in a tertiary care hospital. methods: in a hospit...
BACKGROUND Low serum concentrations of vitamin A and zinc are common in tuberculosis and may have an adverse effect on host cell-mediated responses. The role of adjunctive micronutrient supplementation on treatment outcomes is uncertain. OBJECTIVE The objective was to assess the efficacy of vitamin A and zinc supplementation on sputum smear and culture conversion and time to culture detection...
BACKGROUND Rapid sputum culture conversion at 2 months indicates the sterilizing capacity and potential of regimens to shorten duration of tuberculosis treatment. We compared results of sputum culture conversion by moxifloxacin and control regimens and identified factors affecting sputum culture positivity after 2 months of treatment. METHODS Human immunodeficiency virus-uninfected adults wit...
We read with great interest the recently published study1 on the role of vitamin D on the type and clinical outcome of tuberculosis (TB). The authors did not find any role of baseline vitamin D levels with either the type or clinical outcome but they reported that children with sufficient levels of vitamin D were more likely to have sputum smear conversion at two months than those who did not h...
BACKGROUND Tuberculosis Trials Consortium Study 28, was a double blind, randomized, placebo-controlled, phase 2 clinical trial examining smear positive pulmonary Mycobacterium tuberculosis. Over the course of intensive phase therapy, patients from African sites had substantially delayed and lower rates of culture conversion to negative in liquid media compared to non-African patients. We explor...
