The established risk factors for atherosclerosis fail to fully explain the extent and severity of coronary artery diseases in 50% of the patients. Thus, the causative agents and processes, which may be involved in the pathogenesis of atherosclerosis, are being sought. Notoriously, atherosclerosis and cardiovascular event rates are much lower in developing(More)
INTRODUCTION Activation of the coagulation cascade resulting in thrombin production is a prominent feature of exacerbations in chronic spontaneous urticaria (CU). Autologous serum skin test (ASST) causes wheal-and-flare reactions in 30% to 50% of CU cases. OBJECTIVE The aim of this study was to evaluate the clinical and laboratory data in patients with CU(More)
OBJECTIVE The objective of this study was to define the prevalence of systemic lupus erythematosus (SLE) in patients with myasthenia gravis (MG). METHODS Seventy-eight MG patients recruited unselectively from Israeli MG database were evaluated by medical history, physical examination and serology (ANA at 1:100 and anti-ds-DNA at 1:10 dilution) for the(More)
OBJECTIVES Patients arriving in the emergency department (ED) need rapid and reliable evaluation of their respiratory status. Mainstream end tidal carbon dioxide (ETCO(2)) is one of the methods used for this purpose during general anaesthesia of intubated patients in the operating theatre. Sidestream ETCO(2) (SSETCO(2)) might be a non-invasive, rapid, and(More)
BACKGROUND The aim of the study was to examine effects of Helicobacter pylori eradication on chronic idiopathic urticaria (CU) with and without positive aulogous serum skin test (ASST). METHODS Seventy-eight patients with CU were checked for the positivity ASST and H. pylori urea (13)C-urea breath test ((13)C-UBT). Twenty-one patients were with both(More)
Highly active antiretroviral therapy has dramatically improved the quality of life and life expectancy of patients with human immunodeficiency virus. However, the prolonged use of HAART leads to severe metabolic adverse events. Both HIV infection and HAART can cause changes in lipid and glucose metabolism as well as elevation of blood pressure, promoting(More)
Autoimmune skin diseases are characterized by dysregulation of the immune system resulting in a loss of tolerance to skin self-antigen(s). The prolonged interaction between the bacterium and host immune mechanisms makes Helicobacter pylori (H. pylori) a plausible infectious agent for triggering autoimmunity. Epidemiological and experimental data now point(More)
Chronic idiopathic (spontaneous) urticaria (CIU) is sometimes resistant to the conventional and high doses of antihistamines (AHs). This study compares the clinical and laboratory characteristics of AH responsive and AH-resistant CIU subjects. Clinical and laboratory data were retrospectively collected from 385 CIU patients. Urticaria activity score (UAS),(More)
BACKGROUND There are few data regarding epidemiology and clinical features of urticarial diseases in the elderly population. OBJECTIVE The aim of the study was to determine the clinical and laboratory characteristics of chronic idiopathic urticaria (CIU) in the geriatric population. METHODS Electronic medical records of outpatient allergy consultations(More)
OBJECTIVE To study the role of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) during HIV infection. METHODS Intracellular CTLA-4 expression, determined by flow-cytometry, and proliferative responses to HIV antigens, were studied in peripheral blood mononuclear cells (PBMC) from 93 HIV-1-infected [HIV(+)] patients and 40 HIV-1 seronegative controls.(More)
