purpose: to determine the prevalence of ocular involvement in patients with tuberculosis (tb) infection. methods: all patients with a new diagnosis of tb who were referred to zahedan tuberculosis center underwent a complete ophthalmic examination. any cases of known ophthalmic disease or previous ocular involvement were excluded from the study. prevalence of ocular involvement with 95% confiden...

Background: Natural killer (NK) cells are the effector cells of innate immunity that respond to infection and tumor. Interactions between killer cell immunoglobulin like receptors (KIR) and human leukocyte antigen (HLA) class I molecules regulate NK cells responses to eliminate infected and transformed cells. Objective: To investigate the impact of KIR genes, HLA ligand genes, and KIR-HLA combi...

Background: A number of former studies have shown that tuberculosis (TB) is higher in diabetes mellitus (DM) patients than non-diabetics. Both DM and TB are major public health problems in Iran, and because of the lack of investigation in this field in the region, we conducted this study to evaluate the prevalence of DM in admitted pulmonary tuberculosis patients. Methods: The medical files of...

tuberculosis (tb) and tobacco use are two major alarming global health issues posing immense threats to human populations. mycobacterium tuberculosis (mtb) by activation of macrophages could induce the sequences of cells activation and releases of inflammatory cytokines such as cxcl-8, il-12 and tnf-α which in turn induces the immune system network. however no information is available on other ...

tuberculosis (TB) is a serious health problem in the world.in 1990 among 5.5 million population in the world,nearly 7.5 million new cases reported and 3 million  patients expired due to this problem.because early detectio of TB is very important ,we decided to evaluate the role of fiberoptic bronchoscopy(FOB) in detection of TB in patients with negative smear and negative culture of sputum.in t...

  Introduction: Development of effective immunodiagnostic methods for detection of Mycobacterium tuberculosis infection is crucial. Serodiagnostic methods, based on antibody response to specific antigens could provide promising approaches for rapid, economical and easy to perform diagnostic tests which are crucial for tuberculosis (TB) control. In this study, the level of IgG antibody responses...

background cavitary pulmonary tuberculosis (tb) is rare in children. objectives the aim of this study was to evaluate the characteristics of cavitary pulmonary tb in children. patients and methods this retrospective study was conducted on 97 children less than 15 years old with pulmonary tb to assess the clinical characteristics and radiographic findings of patients with cavitary lesions. resul...

background: protective immune responses induced in the majority of people infected with mycobacterium tuberculosis enable them to control tb infection. objective: the aim of this study was to investigate cd56 and cd16 positive peripheral blood mononu-clear cells (pbmcs) and leukocyte subsets from multi-drug resistant pulmonary tuber-culosis (mdr-tb), and compare them with nonresistant (nr) tb p...

Background and Objective: Tuberculosis (TB) remains an ongoing major public health problem in the world. In recent years, experimental evidenc suggests a link between TB and Vitamin (Vit) D. This study was conducted to determine serum Vit D, calcium (Ca), phosphorus (P), and parathormone (PTH) levels in untreated pulmonary TB (PTB) patients. Materials and Methods: In this case control study, 5...
