Abstract: OBJECTIVE: To evaluate two monotherapies followed by step-up combination therapy with two or three complementary drugs in active rheumatoid arthritis (RA) in comparison with sulphasalazine (SSZ) alone. METHODS: One hundred and twenty-six consecutive patients with early active RA were enrolled in this open controlled clinical trial. The primary end-point was 50% improvement according to the ACR criteria (ACR50) at 6, 12 or 18 months. The secondary end-points were a full response (Magnusson criteria) and/or remission (ACR criteria) at 3 yr. Methotrexate (MTX) (group 1), cyclosporin A (CsA) (group 2) or SSZ (group 3) was used first. After 6 months, a combination of two drugs (CsA and MTX) was employed in groups 1 and 2. SSZ was added after 12 months if improvement was less than ACR50 with the combination. Group 3 continued with SSZ alone. RESULTS: After 6 months, 57% of patients in group 1, 31% of group 2 (MTX vs CsA, P=0.002) and 33% of group 3 (MTX vs SSZ, P=0.01) had reached ACR50 improvement according to intention-to-treat analysis. At month 12 after starting a drug combination, 67% of group 1 and 76% of group 2 had reached ACR50 compared with 24% of group 3. At the 18-month follow-up, 90% of group 1 and 88% of group 2 but only 24% of group 3 had reached ACR50. After 18 months, 62% of group 1, 60% of group 2 and 48% of group 3 showed side-effects and three, five and eight patients in the three groups respectively had dropped out of the study. At the 3-yr follow-up, 9% of the patients in groups 1 and 2 and 7% of group 3 were in remission according to the ACR criteria; according to the Magnusson criteria, 40% showed a full response in groups 1 and 2 but only 21% did so in group 3. CONCLUSION: MTX appears to be the fastest-acting agent. A step-up approach with MTX plus CsA plus SSZ led to a 50% improvement according to the ACR criteria in most patients. After 3 yr, 40% of patients receiving combination therapy and 21% of patients receiving monotherapy showed a full response, while 9 and 7% respectively attained remission.

Abstract: BACKGROUND: Hepatis C virus infection is presently an exclusion criterion to classify Sjögren's syndrome; however, there are distinct clinicopathologic and biologic similarities between HCV-related and SS-related chronic inflammation of mucosa-associated lymphoid tissue and lymphoproliferation that suggest common pathogenetic pathways. OBJECTIVES: To determine whether a subset of patients with sicca syndrome and HCV infection may present a true primary SS rather than a distinct clinicobiologic entity. METHODS: We extensively characterized 20 consecutive patients with positive anti-HCV antibodies and heavy subjective dry eye and/or dry mouth symptoms, plus positive unstimulated sialometry and/or Shirmer's test. We then compared these features with those in HCV-negative primary SS controls (classified according to the latest American-European Consensus Group Classification Criteria for SS). RESULTS: Of the 20 HCV-positive patients with sicca manifestations, 12 (60%) had positive anti-SSA/SSB antibodies (3/12 by enzyme-linked immunosorbent assay and 6/12 by immunoblot) and/or positive salivary gland biopsy (at least 1 focus/4 mm2), which met the strict classification criteria for SS, as in the case of HCV-negative SS controls. Comparing the HCV-positive SS subset with HCV-negative SS controls showed similar female to male ratio (11/1 vs. 46/4), major salivary gland swelling (17% vs. 26%), positive antinuclear antibodies (75 vs. 94%) and positive rheumatoid factor (58 vs. 52%). Significant differences (P < 0.05) were seen in mean age (69 vs. 56 years), liver disease (50 vs. 2%), lung disease (25 vs. 0%), anti-SSA/SSB positivity (25 vs. 90%), and low C3 or C4 (83 vs. 36%). HCV-positive SS patients exhibited a trend for more frequent chronic gastritis (50 vs. 22%), fibromyalgia (33 vs. 14%), peripheral neuropathy (33 vs. 18%), purpura (33 vs. 19%) and cryoglobulinemia (33 vs. 6%). CONCLUSIONS: A major subset of HCV-positive patients with definite subjective sicca symptoms and positive objective tests may indeed present a true, though peculiar, subset of SS. There are strict similarities with key clinical, pathologic and immunologic findings of definite HCV-negative SS. Other features appear more characteristic of HCV infection. When also considering that HCV is sialotropic and may be treated, HCV-related chronic sialadenitis represents a unique opportunity to clarify key pathogenetic events occurring in the large majority of HCV-negative SS; and similarities to typical primary SS, rather than differences, should be taken into account.
