intradermal injection of autologous serum and plasma elicit a cutaneous reactivity in almost 45-60% of patients with chronic idiopathic urticaria (ciu). this reactivity is associated with the presence of auto antibodies against ige or ige receptors. this study was carried out to compare the cutaneous reactivity of autologous serum and plasma skin tests in a series of patients with ciu for dia...
Background: Autologous serum skin test (ASST) evaluates the presence of any serum histamine-releasing factors and histamine-releasing autoantibodies. Autologous serum therapy (AST) is a therapy in which repeated injections of autologous serum are administered intramuscularly for treatment of chronicspontaneous urticaria (CSU). The aim of this study is to evaluate the advantages and compare the ...
Intradermal injection of autologous serum and plasma elicit a cutaneous reactivity in almost 45-60% of patients with Chronic Idiopathic Urticaria (CIU). This reactivity is associated with the presence of auto antibodies against IgE or IgE receptors. This study was carried out to compare the cutaneous reactivity of autologous serum and plasma skin tests in a series of patients with CIU for diagn...
Background Chronic spontaneous urticaria (CSU) patients demonstrate functional autoantibodies against high affinity receptors of IgE (FcerI). Autologous serum skin test(ASST)is mostly used in chronic spontaneous urticaria to show its autoreactivity. ASST positive patients represent a severe group which can be benefited from autoserum therapy (AST). So, aim of our study is to evaluate the effica...
BACKGROUND Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple methods to diagnose autoimmune chronic urticaria. However, the association data of ASST or APST with disease severity and long-term outcome are still unclear. OBJECTIVE The results of ASST and APST might be used to predict urticaria symptom severity and long-term outcomes among chronic spontaneous u...
Background Autoimmune chronic spontaneous urticaria (CSU) is due to mast cell (MC)-activating autoantibodies, which are screened for by the autologous serum skin test (ASST) and basophil tests (BTs). Many CSU patients positive in only one of these tests. How often this occurs why currently unknown. Objectives To characterize prevalence mismatched ASST BTs patients, investigate possible reasons ...
AIM To determine the prevalence of Hp infection in patients with chronic urticaria (CU) and to evaluate the result of autologous serum skin test (ASST) in CU patients with Hp infections. METHODS In this cross-sectional study, 16 patients with chronic urticaria and 16 non-urticaria volunteers were investigated (matched for age and sex). All subjects were examined for Hp infection with the 13C-...
Injection of autologous serum collected during disease activity from some patients with chronic spontaneous urticaria (CU) into clinically normal skin elicits an immediate weal and flare response. This observation provides a convincing demonstration of a circulating factor or factors that may be relevant to the understanding of the pathogenesis and management of the disease. This test has becom...
Background: Autologous serum (ASST) and plasma (APST) skin testing confirm autoreactivity in chronic spontaneous urticaria (CSU). Whole blood autohemotherapy has been used. Plasma even whole may be used instead of with relatively quicker preparation cheaper method especially using the latter centers limited resources. Purpose: The purpose study is to determine if similar intradermal reactions c...
Previous studies indicate that 25-45% of chronic urticaria patients have an autoimmune etiology. Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple tests for diagnosing chronic autoimmune urticaria (CAU). However, there are still some questions about the specificity of these tests. This study consisted of 50 patients with chronic spontaneous urticaria (CSU) and ...
