BACKGROUND Tuberculosis (TB) is a major cause of severe anaemia in patients with human immunodeficiency virus (HIV) infection in South Africa. However, TB can be difficult to diagnose as it may be extra pulmonary and paucibacillary. AIM The aim of this study was to investigate undiagnosed TB in patients with HIV infection and severe anaemia and to identify the optimal investigations for diagn...

background: resistance to anti-tuberculosis (tb) drugs is a global problem. previous studies showed that the prevalence of primary mdr-tb is higher and has been increasing. the purpose of this study was to determine the primary drug resistance in strains isolated from patients with smear-positive of the new cases to anti-tb drugs. methods: in this cross-sectional study, 266 smear positive pulmo...

 Abstract Background: Soil dust has been debated about its effects on public health and the challenge is brought about tuberculosis (TB). The purpose of this study was to investigate the influence of soil dust on pulmonary tuberculosis (PTB) prevalence and its control indices. Methods: The medical files of patients in Khuzestan Health Center were reviewed. The control group included the PTB...

background according to several studies, diabetes mellitus has been recognized as one of the main risk factors for pulmonary tuberculosis (ptb). objectives the main purpose of this study was to determine the frequency of smear-positive pulmonary tuberculosis (tb) in patients with diabetes. materials and methods this cross-sectional study was conducted from april 2010 to december 2011 in ali asg...

BACKGROUND The diagnosis of active pulmonary tuberculosis (TB) remains a challenge in clinic, especially for sputum negative pulmonary TB. Bronchoalveolar lavage fluid (BALF) has higher sensitivity than sputum for detection of Mycobacterium tuberculosis (Mtb). However, bronchoscopy is invasive and costly, and not suitable for all patients. In order to make TB patients get more benefit from BALF...

conclusion fm is more sensitive than zn for diagnosis of tb. however, since fm is more sensitive and rapid, using this method in clinical laboratories with large specimen numbers is recommended. results a total of 102 out of 920 study subjects had pulmonary tb, of them 68 (66.66%) patients were smear positive by either staining method while others were smear negative. the proportion of positive...

BACKGROUND Differential diagnosis between pulmonary tuberculosis (TB) and bacterial community-acquired pneumonia (CAP) is often challenging. The neutrophil-lymphocyte count ratio (NLR), a convenient marker of inflammation, has been demonstrated to be a useful biomarker for predicting bacteremia. We investigated the usefulness of the NLR for discriminating pulmonary TB from bacterial CAP in an i...

Background: Human immunodeficiency virus (HIV) testing strategy for tuberculosis (TB) patients in some high HIV incidence countries has been recommended based on interaction between HIV and TB. Objectives: The present study aimed to determine the prevalence of HIV infection among newly detected pulmonary TB patients. Patients and Methods: In a cross sectional study, 104 cases including 95 non i...

conclusions in the region under study the prevalence of tb among the prisoners was higher than the general population. the main risk factors for pulmonary tb in this population were close contact, idu and hiv infection. results from the reported 4562 patients with tuberculosis, 363 (7.9%) were prison inmates at the time of tb diagnosis. prevalence of tb cases among the prison inmates was 403.3 ...
