Idiopathic Non-histaminergic Angioedema: Successful Treatment with Omalizumab in Five Patients.

Idiopathic non-histaminergic acquired angioedema (InH-AAE) is a rare disease characterized by AE resistant to antihistamines and a chronic course. We report five new cases of InH-AAE (two women and three men) with a rapid and dramatic response to the anti-immunoglobulin-E antibody omalizumab. In our literature review, we found 13 other relevant cases with a good response to this treatment.

Angioedema Triggered by Medication Blocking the Renin/Angiotensin System: Retrospective Study Using the French National Pharmacovigilance Database.

Introduction: Bradykinin-mediated angioedema (AE) is a rare side effect of some medications, including angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB). In France, side-effects to treatments are reported to the national pharmacovigilance database.

Methods: The national MedDRA database was searched using the term "angioedema".

Lack of association of some chemokine system polymorphisms with the risks of death and hepatocellular carcinoma occurrence in patients with alcoholic cirrhosis: a prospective study.

Background: Polymorphisms in genes encoding for the chemokines stromal cell-derived factor-1 (SDF-1)/CXCL12, monocyte chemotactic protein-1 (MCP-1)/CCL2, or for the chemokine receptors, CC chemokine receptor 5 (CCR5) or CC chemokine receptor 2 (CCR2) have been associated with the progression of hepatitis C virus-related liver injury and with various cancer development. Their influence on the prognosis of alcoholic liver disease is unknown.

Patients And Methods: SDF-1 3'A, MCP-1(-2518), CCR5-Delta32 and CCR2-64I polymorphisms, SDF-1alpha, regulated upon activation normal T cells expressed and secreted (RANTES)/CCL5 and MCP-1 sera levels were determined in 222 alcoholic patients, included at the time of cirrhosis diagnosis and prospectively followed up.
