Clinical Trial
Treatment of primary Sjögren's syndrome with hydroxychloroquine: a retrospective, open-label study.
To determine whether patients with primary Sjögren's syndrome (SS), diagnosed according to San Diego criteria, had improvement in their laboratory or clinical features during treatment with hydroxychloroquine (6-7 mg/kg/day) for at least two years. ⋯ In a retrospective study of patients fulfilling San Diego Criteria for SS, we found: (a) sustained improvement of local symptoms (painful eyes, painful mouth) and improvement of systemic manifestations (arthralgias and myalgias) after treatment with hydroxychloroquine 6-7 mg/kg/day over mean three-year follow-up; (b) laboratory analysis showed a significant improvement in their ESR and their quantitative IgG levels; (c) no significant late toxicity was observed in this study cohort. A prospective study of hydroxychloroquine in patients fulfilling San Diego criteria for SS is indicated.

A 34-year-old woman with stable systemic lupus erythematosus (SLE) treated with low-dose prednisone and hydroxychloroquine developed multiple bilateral pulmonary nodules. Open lung biopsy documented lymphocytic interstitial pneumonitis (LIP). LIP should be considered in the differential diagnosis of nodular pulmonary lesions in patients with SLE.
