Brief Summary

Our research contributes to the understanding of some of the basic biology of the salivary glands. The etiology and many of the pathomechanisms of Sjögren's syndrome are unknown. In particular, reasons for the female dominance, late age of onset, fatigue and the prominent involvement of exocrine glands are unknown. We hypothesize, due to the disease characteristics, that the primary target hit by the disease process is the secretory acinar cell and that this cell is particularly damaged in women due to insufficient support, normally provided by dehydroepiandrosterone and its intracrine processing.

PLACEBO COMPARATOR

180 patients divided to two separate groups (each containing 90 patients). This study has a cross-over, wash-out design, which consists of two 4 month treatment period separated by a one month long wash-out period. During one treatment period the patient gets placebo and during one of the treatment periods the patient gets 50mg of dehydroepiandrosterone (DHEA) in the morning.

Drug: dehydroepiandrosterone

Interventions

50 mg of dehydroepiandrosterone in the morning for 4 months in the treatment group.

Also known as: DHEA
