BACKGROUND Manifestation of acute edema in hereditary angioedema (HAE) is characterized by interindividual and intraindividual variability in symptom expression over time. Flexible therapy options are needed. METHODS We describe and report on the outcomes of the highly individualized approach to HAE therapy practiced at our HAE center in Frankfurt (Germany). RESULTS The HAE center at the Fr...
BACKGROUND For safe and efficacious treatment of hereditary angioedema, C1 esterase inhibitor (C1-INH) concentrates should have high purity and high amounts of functional protein. As no pharmacopoeia requirements exist for C1-INH concentrate lot release, biochemical characteristics as declared by the manufacturers may not be compared directly. This study compared the characteristics and purity ...
H ereditary angioedema (HAE) is a serious genetic abnormality involving the complement system and characterized by episodic and sometimes life-threatening airway edema. In 1882, von Quincke (1) published the first detailed description, and 3 yr later, Strubing used the term angioedema to describe this disorder. By 1888, Osler (2) had demonstrated the hereditary nature of the clinical presentati...
BACKGROUND Hereditary angioedema (HAE) is a rare disease caused by C1INH gene mutations, which leads to a deficiency or dysfunction of C1 inhibitor (C1 INH), resulting in recurrent episodes of severe and potentially life-threatening edema. OBJECTIVE To evaluate the efficacy and safety of repeat use of nanofiltered C1 esterase inhibitor (human) (C1 INH-nf) for the short-term treatment of HAE a...
caused by autoantibodies against C1-INH (AAE type II). Reduced C1-INH activity leads to uncontrolled bradykinin formation and to angioedema symptoms. There is no established treatment for AAE. Replacement with plasma-derived C1-INH is effective in most patients with life-threatening attack; however, icatibant, a bradykinin B2 receptor antagonist, may represent an alternative treatment. Methods:...
UNLABELLED Essentials How the Alzheimer's disease (AD) peptide β-amyloid (Aβ) disrupts neuronal function in the disease is unclear. Factor (F) XII initiates blood clotting via FXI, and thrombosis has been implicated in AD. Aβ triggers FXII-dependent FXI and thrombin activation, evidence of which is seen in AD plasma. Aβ-triggered clotting could contribute to neuronal dysfunction in AD and be a ...
Hereditary angioedema is a disease of congenital deficiency or functional defect in the C1 esterase inhibitor (C1-INH) consequent to mutation in the SERPING1 gene, which encodes C1-INH. This disease manifests as recurrent, non-pitting, non-pruritic subcutaneous, or submucosal edema as well as an erythematous rash in some cases. These symptoms result from the uncontrolled localized production of...
The StcE zinc metalloprotease is secreted by enterohemorrhagic Escherichia coli (EHEC) O157:H7 and contributes to intimate adherence of this bacterium to host cells, a process essential for mammalian colonization. StcE has also been shown to localize the inflammatory regulator C1 esterase inhibitor (C1-INH) to cell membranes. We tried to more fully characterize StcE activity to better understan...
BACKGROUND Hereditary angioedema (HAE) is a rare disease caused by C1-esterase inhibitor (C1-INH) deficiency, characterized by periodic attacks of acute edema affecting subcutaneous (SC) tissues and mucous membranes. Human C1-INH concentrate given intravenously (IV) is effective and safe, but venous access may be difficult. We compared SC and IV administration of human pasteurized C1-INH concen...
Background Angioedema is defined as delimited edema that compromises dermis and subcutaneous. May have different causes hypersensitivity, autoimmune, idiopathic, physical factors, angiotensin-converting enzyme inhibitors and C1 esterase inhibitor consumption or disability. The physiopathologic mechanisms depend on the cause. In addition to detailed history, additional tests are needed for targe...
