Human anisakidosis is a parasitic infection caused by the larvae of Anisakis simplex. Classical clinical manifestations include epigastric pain, occlusion, diffuse abdominal pain, appendicitis, and anaphylactoid reactions. Arthralgias or arthritis have been infrequently reported. We present three patients with proven hypersensitivity to A. simplex together with rheumatologic complaints after ingestion of parasitized fishes. A. simplex must be considered in the differential diagnosis of arthralgias/ arthritis especially if associated with urticaria.

Anisakis simplex, a fish parasite of the nematode family, typically infects marine mammals such as whales, dolphins and seals. Human anisakiasis, which is acquired by eating raw or insufficiently heated fish or squid, has gained world-wide importance. Infestation with living larvae caused by eating parasitised fish results in acute upper abdominal pain, nausea and vomiting and may be confused with acute abdomen due to appendicitis and other inflammatory abdominal disorders. Extraintestinal organ manifestations are rare. Endoscopically, inflammation, oedema, erosions and ulcerations may be found. The parasite can been found in up to 50% of patients. Histologically, an eosinophilic inflammation is typical. Acute anisakiasis may be prevented by thorough cooking or deep-freezing the parasitised fish for at least 48 h. IgG-antibodies specific for Anisakis simplex are thought to represent an immunological host reaction against parasitic antigens. More recently, allergic reactions to Anisakis ingestion or exposure, such as urticaria, anaphylaxis and even occupational asthma, have been reported. These allergic reactions may also occur when the fish has been properly cooked, and hence these allergens are thought to be heat-stable. Such cases may be diagnosed by skin tests and the determination of specific Anisakis-IgE. However, the specificity of IgE is low, since they may also be present in exposed asymptomatic individuals. Since the eliciting allergens are temperature-stable, prophylactic dietetic measures are indicated. We report a case from Switzerland acquired during a holiday in Portugal. The patient suffered from recurrent dysphagia and urticaria, and histologically eosinophilic oesophagitis was found. IgG-antibodies and a positive skin prick test to Anisakis simplex support its aetiologic role for the symptoms.

Anisakis simplex is a nematode which can parasitize many different kinds of fish or cephalopods (codfish, salmon, tuna, mackerel, hake, etc). Anisakis simplex can cause different diseases in humans. The human being acquires the larvae by eating raw or undercooked seafood. Acute anisakiasis is probably caused by an inflammatory and/or allergic response in the digestive tract mucosa with abdominal pain. It can also induce IgE-mediated reactions with several clinical manifestations ranging from urticaria/angioedema to anaphylaxis. Chronic anisakiasis results from abscesses or eosinophilic granulomas caused by parasite invasion. This later form can mimic appendicitis, duodenal ulcer, inflammatory bowel diseases and intestinal obstruction. An early gastroduodenoscopy can confirm the diagnosis and prevent the complications. Serodiagnosis of anisakiasis is difficult since many Anisakis antigens show cross-reativity complications. In fact many people have high IgE titles in the absence of obvious allergic reactions to seafoods. As preventive measures heating for 10 min over 65 degrees C or freezing (minus 20 degrees for 24 h) destroys the infectivity of the larval stage but not always prevent allergic reactions.

We present a case with extremely late diagnosis of type II hereditary angioedema (HAE). Given recent advances in HAE treatment, we want to bring physician awareness to this condition and aid in earlier detection. HAE is a disorder associated with episodes of angioedema of the face, larynx, lips, abdomen, or extremities. Late diagnosis of HAE can lead to significant morbidity and is severely impairing due to recurring attacks. The diagnosis of HAE is ordinarily made during childhood and adolescence. Delayed diagnoses in early and middle adulthood have been documented in the literature. Gastrointestinal symptoms are common features of HAE and can be misdiagnosed as disease of primary gastrointestinal pathology, such as irritable bowel syndrome, recurrent pancreatitis, or appendicitis. These attacks are characterized by recurrent attacks of subcutaneous and submucosal edema without the presence of urticaria.We present a case of an elderly veteran whose diagnoses was extremely delayed into the eighth decade of life subsequent to unexplained abdominal symptoms. After diagnosis, the patient's symptoms were well controlled with medication due to advances in HAE treatment. To prevent further atypically delayed diagnoses, physicians should consider HAE in patients with recurrent attacks of unexplained abdominal pain.
