[Salazosulfapyridine-induced eruption. Pustular erythroderma and pseudo-lymphomatous syndrome: 2 cases].

We report two observations of drug eruption due to salazosulfapyridine which occurred 15 to 21 days after introducing the molecule. The two patients were of Carabian origin and presented with fever, erythrodermia which became pustular and a pseudolymphomatous syndrome. Favourable outcome was observed 4 to 6 weeks later. The diagnosis of toxidermia was made based on the strong imputability of salazosulfapyridine in both cases. Severe immunoallergic reactions to this molecule have been described, including fatal cytolytic hepatitis and Lyell syndrome.

Cryoglobulinemia with vasculitis associated with hepatitis C virus infection.

Essential mixed cryoglobulinemia is frequently associated with chronic hepatitis. This report presents four cases of cryoglobulinemia with vasculitis associated with chronic hepatitis related to hepatitis C virus infection. Hepatitis C virus infection was ascertained in the four patients by both the presence in the serum of anti-HCV antibodies detected by the four-antigen recombinant immunoblot assay and of HCV RNA detected by polymerase chain reaction. In two patients tested, anti-HCV antibodies were not detected after centrifugation in the purified cryoglobulin but were detected in the supernatant. HCV RNA was detected in the purified cryoglobulin in all four patients and was detected in the supernatant in three patients. In one patient receiving recombinant interferon alfa, serum aminotransferases normalized and cryoglobulin disappeared; in another patient receiving recombinant interferon alfa, serum aminotransferases remained high and the cryoglobulin persisted. The presence of HCV RNA in the cryoglobulin and the parallelism of the changes of the cryoglobulinemia and of the serum aminotransferases during recombinant interferon alfa administration suggest that HCV infection is responsible for the production of cryoglobulinemia and vasculitis. It is proposed that HCV infection is a cause of cryoglobulinemia associated with chronic hepatitis.

[Comparative study of the development and prognosis of pemphigus vulgaris and seborrheic pemphigus].

Traditionally, the prognosis of pemphigus erythematosus is thought to be more favourable than that of pemphigus vulgaris. A retrospective study of the records of 10 patients with pemphigus erythematosus and 13 patients with pemphigus vulgaris was set up to compare the courses of the two diseases. This comparison, carried out in populations with similar age, sex ratio, pretreatment duration of the disease and treatment received, showed that relapses were more frequent in the course of pemphigus erythematosus, whereas remissions, mean duration of the disease and iatrogenic complications were the same in both groups. This study, therefore, throws some doubts on the dogma of relative mildness of pemphigus erythematosus, which goes back to a period long before systemic corticosteroid therapy was known. Mortality studies performed since the event of this treatment have shown that the prognosis had improved and tended to be the same in both diseases. The other data concerning the course of treated pemphigus erythematosus are little known and were never compared with those concerning pemphigus vulgaris. Our study shows that treatments similar to those of pemphigus vulgaris are necessary to obtain remissions in pemphigus erythematosus and that these diseases share the same evolutive profile. However, the question of the best therapeutic strategy to be used has not yet been answered.
