Background: Microscopic smear examination is the most common test in tuberculosis (TB) detection. It is, however, not strong enough to identify TB in the majority of afflicted individuals; thus, a significant number of TB patients are smear negative and capable of transmitting the infection. The aim of this study was to evaluate the rate of smear-negative TB in northwest Iran.Methods: In this c...
study of kir expression and hla ligands in cd56+ lymphocytes of drug resistant tuberculosis patients
analysis of receptor–ligand interactions in the context of diseases necessitates to understand how hla–kir genotypes function in diseases. although cd56+ lymphocytes are derived from multiple lineages, they share a functional association with immunosurviellance and antimicrobial responses. the present study aimed to determine whether kir phenotype in cd56 lymphocytes and corresponding...
Background: HIV infection reduces the immune system and is the most significant factor in the spread of TB in recent years and one of the causes of death in HIV -seropositive patients. TB is the most commonly diagnosed opportunistic infection and the most frequent direct cause of death among HIV infected patients. The HIV infection can accelerate progression of TB infection to active TB disease...
Background and Aim: Pulmonary tuberculosis (TB) infection is common in patients infected with the Human immunodeficiency virus (HIV). In this study, we evaluated thoracic CT scan findings of HIV/TB co-infection, before and after anti-TB treatment. Materials and Methods: In this retrospective cross-sectional study, pre-and post-treatment thoracic CT scans of patients diagnosed with HIV and defin...
Background: Interferon gamma (IFN-γ), a cytokine produced by a variety of cells is involved in the immune response against M. tuberculosis. It activates the production of other cytokines and molecules that kill mycobacterium. IFN-γ also has diagnostic role in identification of active and latent tuberculosis. Objective: To determine the level of IFN-γ in the blood of TB patients. Methods: Ninety...
Introduction: Tuberculosis (TB) is one of the oldest diseases worldwide with a great deal of mortality. It consists of either pulmonary or extra-pulmonary type with 15% of tuberculosis cases are caused by the latter. The most common site of extra-pulmonary TB is in lymph glands (nearly 40% of the cases). The objective of the current study is the epidemiological assessment of the contributors of...
Background and purpose: Identifying the types of immune cells in patients with tuberculosis (TB) including single-core and multi-core is of great benefit in control and treatment of these patients. The aim of this research was to compare differential cell count in Bronchoalveolar lavage (BAL) samples in patients with and without TB. Materials and methods: In this descriptive-analytical...
Background: The incidence of tuberculosis (TB) has increased in recent years in both developed and developing countries. Skeletal tuberculosis occurs in approximately 1% of patients with tuberculosis. The present study aimed to evaluate the epidemiology of skeletal tuberculosis in Golestan province in northeastern Iran during 2005-2014.Methods: In the present retrospective study, the epidemiolo...
Introduction: About one third of the world's population is infected with tuberculosis (TB) and each year, about 1.5 to 2 million people die from TB. Procalcitonin (PCT) is an inflammatory marker that its level has variable Materials and Methods: This conducted on patients with pulmonary TB. Data were collected using a check list. The serum level of PCT was measured by ELISA test at the beginnin...
purpose: to evaluate the diagnosis of intraocular tuberculosis (tb) with polymerase chain reaction (pcr) and to report 13 cases of presumed intraocular tb. methods: of 168 patients with uveitis, 13 patients (7.74%) had criteria for intraocular tb (tb group). thirteen patients with non-tb uveitis were randomly selected as the control group. samples for pcr were obtained from the aqueous humor. s...
