Recent studies suggest that autoimmune mechanisms may be involved in the etiology of chronic idiopathic urticaria (CIU). There is a higher prevalence of B12 deficiency in autoimmune diseases and possibly in gastric Helicobacter pylori (H. pylori) infection. The frequency of B12 deficiency in CIU is unknown. Our objective in this study was to determine the(More)
BACKGROUND AND OBJECTIVE Pollens from the Cupressaceae family are considered important allergens in the Mediterranean area, though reports of the prevalence of allergic symptoms have ranged from 1.04% to 35.4%. Our aim was to detect the prevalence of cypress pollen sensitization and determine its clinical importance in patients with seasonal respiratory(More)
BACKGROUND The oesophagus is normally devoid of eosinophils. There are some disorders accompanying with eosinophil infiltration. Food allergy has been reported as a common reason, especially in children but some other studies have also indicated that aeroallergens might have a role in oesophageal eosinophil accumulation. OBJECTIVE In this study we(More)
BACKGROUND Studies show that nerve growth factor (NGF) exhibits immunomodulatory activity. This neurotrophin is found at high levels in the serum of asthmatic individuals, is released during allergic reactions, and is reported to augment in vitro histamine and leukotriene C4 release by human basophils. OBJECTIVE Because basophils represent a substantial(More)
We report newly presenting systemic and local allergic reactions to egg in a 55-year-old woman. The patient did not have a history of egg allergy in childhood or occupational exposure to egg proteins; nor did she report any disease that is known to be related to food allergy. A skin prick test with commercial extracts, prick-to-prick test, CAP(More)
Asthma is a disease characterized by chronic airway inflammation. Many inflammatory cells and molecules contribute to its pathogenesis. Soluble tumor necrosis factor receptors (sTNFRs) and soluble intercellular adhesion molecule-1 (sICAM-1) play regulatory roles in the inflammation. But their roles in the inflammation of asthma have not been well defined.(More)
BACKGROUND The precision of the methods used to diagnose latex allergy is of great importance due to false-positive results. Neither the skin prick test (SPT) nor the latex-specific IgE assay has 100% diagnostic accuracy. We analysed the diagnostic value of latex-specific IgE by the first-ever concomitant use of the SPT and nasal provocation test (NPT). (More)
BACKGROUND Common variable immunodeficiency (CVID) is characterized by hypogammaglobulinemia, defective antibody production, and recurrent upper and lower airway tract infections. OBJECTIVES To reveal the clinical heterogeneity of this condition, analyze the high frequency of respiratory and gastrointestinal complications despite satisfactory trough(More)
Allergy has been reported as an important factor in the etiology of nasal polyposis. Asthma, chronic sinusitis and aspirin hypersensitivity are frequently found together with nasal polyposis. Total IgE, RAST for specific IgE and skin prick test were used to investigate the incidence of allergy in 95 patients with nasal polyposis. In addition,(More)
BACKGROUND No published data presently exist concerning hereditary angioedema (HAE) in Turkey. The aim of the study was to initiate a preliminary multicentric evaluation about HAE and to determine the genetic properties of Turkish patients. METHODS Based on records drawn from four medical centers we identified a total of 70 subjects, belonging to 60(More)
