Abstract: To describe the clinical and immunologic patterns of disease expression of patients with chronic hepatitis C virus (HCV) infection and positive antimitochondrial antibodies (AMA). We investigated the presence of AMA in 237 consecutive HCV patients with extrahepatic manifestations from an International Registry. AMA were detected by indirect immunofluorescence in triple rat tissue (liver, stomach and kidney), aceton-fixed criosections and FITC-conjugated rabbit anti-human immunoglobulins. We found positive AMA in 18 (8%) out of 237 HCV patients. All patients were female with a mean age at protocol inclusion of 65.8 years (ranging from 37 to 87 years). Twelve (67%) patients fulfilled classification criteria for systemic autoimmune diseases (SAD), including Sjögren's syndrome (n = 7), systemic sclerosis (n = 3) and systemic lupus erythematosus (n = 2). Fourteen (78%) of the HCV-AMA patients presented at least one of the highly suggestive characteristics of primary biliary cirrhosis (PBC): 9 (50%) had a specific M2 pattern, 6 (33%) had more than twice normal levels of alkaline phosphatase, 5 (28%) had raised IgM levels and 4 (22%) a histological pattern compatible with PBC. Five (28%) patients developed neoplasia after detection of AMA. Seven (39%) patients died, due to neoplasia (n = 4), cirrhotic complications (n = 2) and hepatopulmonary syndrome (n = 1). We describe a subset of HCV patients with positive AMA who presented a broad spectrum of clinical features, including liver, autoimmune and neoplasic manifestations. Two-thirds of these patients presented an associated SAD, mainly Sjögren's syndrome or systemic sclerosis, together with a high frequency of multiple autoantibodies and an increased prevalence of cirrhosis and neoplasia.

Abstract: We conducted the current study to characterize the clinical presentation of primary Sjögren syndrome (SS) in a large cohort of Spanish patients and to determine whether epidemiologic, clinical, and analytical features modulate disease expression. Patients were from the GEMESS Study group, which was formed in 2005 and included 12 Spanish reference centers. By March 2007, the database included 1010 consecutive patients, recruited since 1994, both incident and prevalent cases.The cohort included 937 women and 73 men (ratio, 13:1), with a mean age of 53 years at diagnosis and 59 years at inclusion in the registry. Multivariate analysis showed that male patients had a lower frequency of thyroiditis, Raynaud phenomenon, and antinuclear antibodies. Young-onset patients had a low degree of sicca involvement (xerostomia and parotid enlargement) and a high frequency of immunologic markers (anti-Ro/SS-A and low C4 levels). Patients with disease duration of more than 10 years had a higher prevalence of xerophthalmia, parotid enlargement, lung involvement, and peripheral neuropathy in comparison with incident cases. The subset of patients with anti-Ro/La antibodies had the highest prevalence of most systemic, hematologic, and immunologic alterations (higher frequency of Raynaud phenomenon, altered parotid scintigraphy, positive salivary gland biopsy, peripheral neuropathy, thrombocytopenia, and rheumatoid factor). Hypocomplementemia was associated with a higher frequency of vasculitis and lymphoma, and cryoglobulins with a higher frequency of parotid enlargement, vasculitis, and leukopenia.Epidemiologic, clinical, and analytical features have a significant impact on the clinical presentation of primary SS, influencing the results of the main diagnostic tests, the prevalence and diversity of extraglandular involvement, and the frequency of the main immunologic markers. Primary SS should be considered as a systemic autoimmune disease that can express in many guises beyond sicca involvement.

Abstract: OBJECTIVE: To characterize the clinical and immunologic patterns of expression, response to therapy, and outcome of patients with Sjögren's syndrome (SS) and associated hepatitis C virus (HCV) infection who developed B cell lymphoma. METHODS: Various international reference centers constituted a multicenter study group with the purpose of creating a registry of patients with SS-HCV who developed B cell lymphoma. A protocol form was used to record the main characteristics of SS, chronic HCV infection, and B cell lymphoma. RESULTS: Twenty-five patients with SS-HCV with B cell lymphoma were included in the registry. There were 22 (88%) women and 3 (12%) men (mean age 55, 58, and 61 years at SS, HCV infection, and lymphoma diagnosis, respectively). The main extraglandular SS manifestations were cutaneous vasculitis in 15 (60%) patients and peripheral neuropathy in 12 (48%); the main immunologic features were positive rheumatoid factor (RF) in 24 (96%) and type II cryoglobulins in 20 (80%). The main histologic subtypes were mucosa-associated lymphoid tissue (MALT) lymphoma in 11 (44%) patients, diffuse large B cell lymphoma in 6 (24%), and follicular center cell lymphoma in 6 (24%). Fifteen (60%) patients had an extranodal primary location, most frequently in the parotid gland (5 patients), liver (4 patients), and stomach (4 patients). Twelve (52%) of 23 patients died after a median followup from the time of lymphoma diagnosis of 4 years, with lymphoma progression being the most frequent cause of death. Survival differed significantly between the main types of B cell lymphoma. CONCLUSION: Patients with SS-HCV and B cell lymphoma are clinically characterized by a high frequency of parotid enlargement and vasculitis, an immunologic pattern overwhelmingly dominated by the presence of RF and mixed type II cryoglobulins, a predominance of MALT lymphomas, and an elevated frequency of primary extranodal involvement in organs in which HCV replicates (exocrine glands, liver, and stomach).

Abstract: BACKGROUND AND OBJECTIVE: We aimed to asses the efficacy of pilocarpine tablets as a symptomatic treatment for dry mouth and dry eyes in patients with primary Sjögren's syndrome (SS). PATIENTS AND METHOD: We included 40 patients with SS (38 women and 2 men), mean age 49.2 years (range, 35-68), with severe xerostomia and xerophthalmia. Objective tests (salivary scintigraphy, Schirmer's test, break-up time, Rose Bengal staining) and subjective tests (symptoms' questionnaire) were carried out before starting treatment and 6 months later to evaluate any glandular function improvement. RESULTS: All patients initially received 15 mg daily of pilocarpine. Twelve (30%) patients received 20 mg daily. Dry mouth-related symptoms improved in 57.5% of patients and dry eyes-related ones improved in 35%. Scintigraphic studies demonstrated an objective improvement of the glandular function in 35% patients. Ocular tests showed an improvement in 30% cases. CONCLUSIONS: Pilocarpine therapy is useful to improve xerostomia and xerophthalmia in SS patients with moderate and severe glandular involvement. However, we have not observed a good correlation between subjective improvement of symptoms and the objective test results.

Abstract: Salivary gland dysfunction has been described in patients undergoing radioiodine therapy but associated lacrimal gland dysfunction (sicca syndrome) has never been reported. We conducted a prospective cohort study with follow-up for up to 3 y in a tertiary care university center to determine the prevalence of sicca syndrome in patients after high-dose radioiodine treatment. METHODS: From January 1990 to December 1995, all patients undergoing radioiodine therapy (n = 79) with a standard dose of 925 MBq to 18.5 GBq (25-500 mCi) were interviewed using a standardized questionnaire to determine subjective ocular and oral dryness and were examined for objective lacrimal and salivary gland dysfunction. RESULTS: After radioiodine treatment, 32.9% of the patients reported subjective xerostomia and 25.3% reported subjective xerophthalmia in the first year of follow-up. Xerostomia persisted to the second year of follow-up in 20.3% of cases and was still present >3 y after the last dose of radioiodine in 15.2% of cases. Xerophthalmia persisted to the second year of follow-up in 17.7% of cases and was still present in the third year of follow-up in 13.9% of cases. Severe xerostomia occurred in 4 patients. Reduced salivary and lacrimal gland function was documented in 40 (50.6%) and 14 (17.7%) of the 79 cases, respectively, in the first year of follow-up. Objective xerostomia persisted in 13.9% of cases to the second year of follow-up and was still present in all patients >3 y after the last radioiodine application. Keratoconjunctivitis sicca persisted in 11 patients (13.9%) to the second year of follow-up but was only present in 6 patients (7.6%) >3 y after the last radioiodine application. Additionally, 28/79 patients (35.4%) who had a normal salivary gland scintigraphy previously showed reduced salivary gland function in the third year of follow-up. No significant dependence on cumulative treatment was found for objective xerostomia or xerophthalmia, but doses >11.1 GBq (300 mCi) were related to stage 3 dysfunction on salivary gland scintigraphy. CONCLUSION: Salivary and lacrimal gland dysfunction (sicca syndrome) is relatively frequent after radioiodine therapy. In most cases this is a transient side effect, but in some patients it may persist for a long period or appear late.
