[TWO CASES OF α-GAL SYNDROME CAUSED BY INGESTION OF WILD BOAR MEAT].

α-Gal syndrome (AGS) is an allergic reaction to galactose-α-1,3-galactose (α-gal) found in the salivary glands of ticks, mammalian meat excluding primates, and some antibody preparations, such as cetuximab. We report two cases of AGS diagnosed after ingestion of wild boar meat. Patient 1, a male in his 70s, developed anaphylactic shock about 3 h after eating wild boar meat.

Photoprovocation test and immunohistochemical analysis of inducible nitric oxide synthase expression in patients with Sjögren's syndrome associated with photosensitivity.

Background: Annular erythema (AE) in Sjögren's syndrome (SS) usually develops on areas of sun-exposed skin and is exacerbated during summer.

Objectives: To evaluate photosensitivity in SS and to investigate the involvement of ultraviolet (UV) radiation in the development of AE in SS.

Methods: Phototesting with UVA and UVB was performed on 14 SS patients, including 10 with primary SS.

Porphyria cutanea tarda and hepatitis C virus infection.

We studied the prevalence of hepatitis C virus (HCV) infection in 20 Japanese patients with sporadic-type porphyria cutanea tarda (PCT). Seventeen of the 20 patients (85%) had anti-HCV antibodies. Biochemical remission was observed in nine patients, six of whom still had positive HCV RNA copies.
