Relapsing polychondritis and familial Mediterranean fever--an association.

Relapsing polychondritis (RP) and familial Mediterranean fever (FMF) are systemic inflammatory disorders with seemingly distinct genetic and pathophysiologic mechanisms. An association between these disorders has been described based on a single case report with few clinical details available. We recently encountered a patient with biopsy-proven RP and genetically confirmed FMF. Following identification of this individual, we conducted a retrospective review of all cases of RP in our institution from 2000-2009 and identified one additional patient with RP who is also a genetic heterozygote for FMF. These cases highlight the previously reported but sparsely documented relationship between these seemingly separate disorders.

Granulomatous hepatitis and Sjogren's syndrome: an association.

BACKGROUND: Sjogren's syndrome (SS) is a common autoimmune disorder in which liver involvement is frequent, but generally mild and subclinical. Multiple hepatic histologies have been reported, but to our knowledge an association with granulomatous hepatitis (GH) has never been described. We recently evaluated an individual in whom biopsy-proven GH was associated with concomitant SS. OBJECTIVE: To clarify the possible association between GH and SS. METHODS: We retrospectively reviewed all cases of biopsy-proven GH seen in our institution from 1991 to 2004. Overall, there were 16 individuals with GH identified of which 4 were considered idiopathic in origin. These individuals underwent an extensive evaluation for the presence of SS as well as other disorders known to be associated with GH. RESULTS: Of the 4 identified cases with a previously suspected idiopathic GH, 3 met criteria for primary SS. All 3 individuals underwent minor salivary gland biopsy, which was diagnostic for this condition. CONCLUSIONS: These results suggest a likely association between these 2 conditions. Further epidemiological studies will be necessary to confirm this finding.
