1.Clinical constellation of annular erythema associated with anti-Ro/La autoantibodies.
Journal of Korean Medical Science 2000;15(2):199-202
Annular erythema (AE) associated with anti-Ro (SSA) and/or La (SSB) autoantibody in patients with Sjogren syndrome (SS) or with SS/systemic lupus erythematosus overlap syndrome (SS/SLE), has recently been described in Orientals, and it may be a counterpart of annular skin lesion of the subacute cutaneous LE seen mostly in Caucasians. The author examined five Korean AE patients in respect to dinical diversity. In this small-sample study, subtle differences appeared between individual cases regarding the serologic features and the diagnoses of the disease. Among the five cases, four had circulating anti-Ro and anti-La antibodies, and one had only anti-La. Regarding the diagnosis, one was SS/SLE, two were primary SS, and the remaining two were only "AE associated with anti-Ro/La antibody". There seem to be a wide clinical spectrum in the disease expression of AE associated with anti-Ro/La autoantibody than previously thought.

2.Primary Extranodal Marginal Zone B-cell Lymphoma of Mucosa-Associated Lymphoid Tissue-type in the Thymus of a Patient with Sjogren's Syndrome and Rheumatoid Arthritis.
Journal of Korean Medical Science 2003;18(6):897-900
Primary thymic marginal zone B-cell lymphoma (MZBL) of mucosa-associated lymphoid tissue (MALT)-type is a very rare disease with distinct clinicopathologic features. I herein report a rare case of primary thymic MZBL of MALT-type arising in the thymus in a patient with Sjogren's syndrome and rheumatoid arthritis. A mediastinal mass was detected by computerized tomography in a 43-yr-old Korean woman with a history of Sjogren's syndrome and rheumatoid arthritis and the thymus was resected through median sternotomy. The solid and nodular tumor (7x6x3cm) was confined in the thymus. Histologically, the lymphoid infiltrate comprised monotonous centrocyte-like cells with monocytoid cells, small lymphocytes, and plasma cells. Prominent lymphoepithelial lesions were formed by centrocyte-like cells infiltrating the Hassall's corpuscles. Immunohistochemically, the tumor cells were positive for CD20, CD79a, and bcl-2 and negative for CD3, CD5, CD10, CD23, and bcl-6. IgA and kappa light chain restriction were also found in plasma cells in the tumor. Sjogren's syndrome and rheumatoid arthritis are known to be associated with MALT lymphoma and were considered to play an important role in the development of malignant lymphoma in this patient.

Anti-Ro autoantibody is associated with Sjogren's syndrome (SS), systemic lupus erythematosus (SLE), and neonatal lupus syndrome (i.e., congenital complete heart block in newborns). Generally, the adult atrioventricular (AV) node is believed to be relatively resistant to the scarring effects of anti-Ro/anti-La autoantibodies. However, there have been some reports of adult complete AV block in SS and SLE patients. Here, we report a case of complete heart block in primary SS with anti-Ro autoantibodies, with no other risk factor for the development of heart block, and review their etiological association.

The effect of hydroxychloroquine (HCQ) on dry eye has not been fully determined. This study aimed to compare the 12-week efficacy of HCQ medication with that of a placebo in the management of dry eye in primary Sjögren's syndrome (pSS). A double-blind, randomized control study was conducted in 39 pSS subjects from May 2011 through August 2013. pSS was diagnosed based on the classification criteria of the American-European Consensus Group. Subjects received 300 mg of HCQ or placebo once daily for 12 weeks and were evaluated at baseline, 6, and 12 weeks, with a re-visit at 16 weeks after drug discontinuance. The fluorescein staining score, Schirmer test score, tear film break-up time (TBUT), and ocular surface disease index (OSDI) were measured, and tears and blood were collected for ESR, IL-6, IL-17, B-cell activating factor (BAFF), and Th17 cell analysis. Color testing was performed and the fundus was examined to monitor HCQ complications. Twenty-six subjects completed the follow-up. The fluorescein staining score and Schirmer test score did not differ significantly. The OSDI improved with medication in the HCQ group but was not significantly different between the groups. TBUT, serum IL-6, ESR, serum and tear BAFF, and the proportion of Th17 cells did not change in either group. HCQ at 300 mg daily for 12 weeks has no apparent clinical benefit for dry eye and systemic inflammation in pSS (ClinicalTrials.gov. NCT01601028).
