Epidemiological characteristics of sarcoidosis differ according to geographical distribution. The aim of our study was to disclose epidemiological characteristics in our country. The data was collected from investigators, who sent information on newly-diagnosed patients via internet. In 2 years 198 female and 95 male patients were enrolled to the study(More)
Vitamin D receptor (VDR) gene variants may play a key role in the susceptibility to tuberculosis (TB). We have investigated the association BsmI, TaqI, FokI polymorphisms in the VDR gene with susceptibility to tuberculosis. This study included 128 patients with TB (pulmonary and extrapulmonary TB) and 80 healthy subjects living in Istanbul, Turkey. Genetic(More)
SETTING Mycobacterium tuberculosis bacilli spread by the hematogenous route during primary infection and reactivate later. OBJECTIVE To compare factors influencing the reactivation site. DESIGN A total of 236 pulmonary tuberculosis (PTB) and 139 extra-pulmonary TB (EPTB) cases were compared in terms of age, co-morbid disease, immunosuppressive drug use,(More)
Tuberculosis (TB), caused by Mycobacterium tuberculosis, is an infectious disease in humans killing nearly three million people and eight million cases annually. The cytokines TNF-alpha and IL-10 have been implicated in the pathogenesis of TB. Certain single nucleotide polymorphisms within the promoter region of the IL10 and TNF genes have been associated(More)
NRAMP1 gene has multiple pleiotropic effects on macrophage activation pathways. These pleiotropic effects may increase resistance to infections such as tuberculosis (TB), but may also lead to susceptibility of autoimmune diseases such as rheumatoid arthritis (RA). It has been hypothesized that allele 3 would be associated with autoimmune diseases, whereas(More)
Systemic sclerosis (SSc), also termed as "scleroderma", is a progressive, systemic disease of unknown origin characterized by excessive fibrosis, vascular abnormalities and immune dysfunction. Extracellular matrix (ECM) production by fibroblasts in SSc is modulated and regulated by cytokines. Since IL10 has antiinflamatory properties and, contributes to the(More)
Systemic sclerosis (SSc), also termed "scleroderma," is a progressive, systemic disease of unknown origin characterized by excessive fibrosis, vascular abnormalities and immune dysfunction. Nramp 1 gene has multiple pleiotropic effects on macrophage activation pathways, including up-regulation of the chemokine/cytokine genes KC, tumor necrosis factor alpha,(More)
The objective of the current study was to determine survival and factors that affect survival in progressive systemic sclerosis (SSc) with pulmonary involvement. A total of 102 SSc patients with pulmonary involvement, diagnosed between 1994 and 2008, enrolled into the study. Pulmonary involvement was defined based on the presence of interstitial changes on(More)
Systemic sclerosis (SSc) is an autoimmune disease characterized by inflammation and fibrosis of the skin and visceral organs. Fibrosis associated with SSc is characterized by an increased synthesis of a wide range of extracellular matrix (ECM). TGF-beta is a pluripotent cytokine in a wide range of cell types. In particular it has been found to be a potent(More)
Pericardial and lung involvement in rheumatoid arthritis (RA), suspected to be less severe in a developing nation (Turkey), have been evaluated. We have studied clinical, echocardiographic and pulmonary findings (radiological and functional) in 93 consecutive Turkish patients with definite/classical RA. Findings were compared with those of a group of(More)
