title: Tumor necrosis factor-alpha release during systemic reaction in cold urticaria.
abstract: Primary cold urticaria (PCU) characterized by the association of urticaria, angioedema, and sometimes a shock-like reaction after cold exposure, is usually considered to be linked with histamine and prostaglandin D2 release by mast cells. To determine the involvement of cytokines, we studied the release of tumor necrosis factor-alpha (TNF-alpha) in the blood of the efferent vein after immersion of the hand in chilled water. Five patients with PCU were compared with a control population (three patients with nonphysical urticaria and three healthy subjects). Among patients with PCU who underwent the cold immersion test, two exhibited a shock-like reaction with a large urticarial plaque (patients 1 and 2), one had only a mild cutaneous reaction, and two had no reaction. Patient 1 was reevaluated after 6 months of treatment with H1 and H2 antihistamines: he did not respond to this challenge. All controls were strictly negative. Histamine was released within the first minute after the challenge in the three patients with PCU, but at a higher level for the two patients who had a systemic reaction. TNF-alpha was undetectable in the blood of the patient with only a mild cutaneous reaction, whereas TNF-alpha release was observed for the two patients with a systemic reaction, 2 and 6 minutes after the end of the cold immersion test. The two other patients and the control subjects released neither histamine nor TNF-alpha. In parallel, pathologic and immunohistochemical (with a rabbit anti-TNF-alpha antibody) studies were performed on skin biopsy specimens collected 10 minutes after ice-cube test.(ABSTRACT TRUNCATED AT 250 WORDS)
