A 44-year-old woman with C1q esterase inhibitor deficiency was seen in consultation for recurrent right upper quadrant abdominal discomfort, nausea, and vomiting. Each of these episodes was accompanied by concomitant peripheral edema. Initial diagnostic efforts were fruitless. In time, intermittent elevations in amylase and lipase developed, and a diagnosis of relapsing pancreatitis was made. We contend that the patient's recurrent acute pancreatitis is associated with her hereditary angioedema. Possible pathogenesis could involve intermittent intrapancreatic edema with partial ductal obstruction or loss of inhibition on the kallikrein-kinin system.

Ten patients with frequent attacks of non-hereditary angioedema were treated with tranexamic acid or placebo in a double blind manner, each period lasting 3 months. During the tranexamic acid period nine patients became symptom-free, or substantially improved, while one was unaffected (P less than 0.05). In four patients itching was a major accompanying complaint which was relieved in three. Diarrhoea and abdominal discomfort were more pronounced during tranexamic acid treatment (P less than 0.05), but only necessitated dose reduction in one patient. Four years later contact was obtained with eight of the nine responders and six were still taking tranexamic acid regularly, while in two patients the attacks were so infrequent that the drug was not taken regularly.

C1 inhibitor (C1-INH) deficiency results in bouts of mucocutaneous edema and may be inherited (hereditary angioedema) or acquired (acquired angioedema). The syndrome of acquired angioedema, characterized by the adult onset of angioedema and by the lack of evidence of inheritance of the disease, may be associated with lymphoproliferative or other malignant diseases (type I) or with the presence of autoantibodies to C1-INH (type II); this is a rare variant form of C1-INH deficiency with angioedema. We report here a case of acquired C1-INH deficiency with angioedema, hypotension and abdominal discomfort observed in a 71-year-old man in whom complement abnormalities and autoantibodies against C1-INH have been observed and who was classified as having an autoimmune C1-INH deficiency. From the therapeutic point of view after resolution of the acute attacks, high doses of tranexamic acid have been able, at first, to decrease the frequency and the severity of the symptoms, and subsequently to provide a long symptom-free time.

Hereditary angioedema is an autosomal dominant condition with a typical presentation of diffuse edematous, painless, and nonpitting swelling of the soft tissues. The disease manifests itself primarily in the extremities, face, airway, and abdominal viscera. Proper diagnosis and treatment are essential as this condition has the capacity of becoming life-threatening due to potential airway embarrassment. This case report demonstrates the complexity of diagnosing and treating hereditary angioedema. Hereditary angioedema often is overlooked on a differential diagnosis of patients suffering from diffuse swelling and/or abdominal discomfort. Nonetheless, the diagnosis of hereditary angioedema should be included when assessing patients who display the proper symptomology and familial history of the condition.

Hereditary angioedema (HAE) is a condition that results from an autosomal dominant trait. It manifests as attacks of swelling involving the extremities, trunk, abdominal viscera, face, neck, or airway. The attacks may occur spontaneously, without any identifiable trigger, or may be the result of a specific trigger, such as a minor tissue trauma. The symptoms of an attack range from abdominal discomfort to a swelling of the upper extremities to a laryngeal edema that can lead to severe airway obstruction. Therapy for HAE can be divided into three distinct phases: treatment for acute attacks, short-term prophylaxis, and long-term prophylaxis. Treatment for an acute attack is largely supportive, including administration of epinephrine and antihistamines to maintain a patent, reliable airway. Shortterm prophylaxis includes fresh frozen plasma and corticosteroids. Long-term prophylaxis includes use of androgens and antifibrinolytics, as well as the avoidance of known triggers. Prior to the advent of such therapies, mortality from an acute attack of HAE was reported as high as 30%. Repeated episodes of unexplained cutaneous edema or abdominal discomfort may be caused by HAE. The nurse's role focuses on prevention of complications and supportive care, as well as education of the patient to minimize risk factors that may cause further episodes.
