Abstract
Interstitial lung disease (ILD) has been recognized as an extrahepatic manifestation ofprimary biliary cholangitis (PBC), althoughlimited data are available on its prevalence and clinical significance. Therefore, we evaluated the occurrence and clinical features of ILD in a cohort of PBC patients. Ninety-three individuals without concomitant rheumatic diseases were enrolled in our prospective cohort study. All patients underwent chest high-resolution computed tomography (HRCT). Liver-related and lung-related survival wereassessed. A lung-related outcome was defined as death from ILD complications; a liver-related outcome was defined as liver transplantation or death from liver cirrhosis complications. HRCT findings suggestive ofILD were detected in 38 patients (40.9%). A sarcoid-like pattern of PBC-associated ILD was the most frequent, followed by subclinical ILD and organizing pneumonia. Patients with ILD were less likely to have liver cirrhosis and liver-related symptoms and presented with higher serum immunoglobulin M(IgM) and M2 subtype antimitochondrial antibodies (AMA-M2) positivity rates. In a multivariate analysis, the absence of liver disease symptoms at the disease presentation (OR 11.509; 95% CI 1.210-109.421; p = 0.033), the presence of hepatic non-necrotizing epithelioid cell granulomas (OR 17.754; 95% CI 1.805-174.631; p = 0.014), higher serum IgM (OR 1.535; 95% CI 1.067-2.208; p = 0.020) and higher blood leukocyte count (OR 2.356; 95% CI 1.170-4.747; p = 0.016) were independent risk factors associated with ILD in PBC. More than a third of patients with ILD showed no respiratory symptoms, and only one ILD-related death occurred during a follow-up of 29.0 months (IQR 11.5; 38.0). Patients with ILD had better liver transplant-free survival.ILD in PBC had a benign course and was associated with a lower liver disease severity. PBC-associated ILD should be included in a list of differential diagnoses of ILD.

Clinical and immunological features of Sjögren's syndrome in patients with primary biliary cirrhosis with emphasis on focal sialadenitis. ACTA MEDICA SCANDINAVICA 2009; 224:611-9.

Abstract
Serological and pathological findings in 21 patients with primary Sjögren's syndrome (primary SS) were compared with those in 32 patients with primary biliary cirrhosis (PBC). In ELISA, anti-SS-B/La antibodies were detected in sera from 14 (67%) of the patients with primary SS, but only from 12 (38%) of those with PBC. With the Ouchterlony test, anti-SS-A/Ro antibodies were found in sera from 15 (71%) of the primary SS patients, but in no PBC patient. Of those PBC patients investigated prospectively with objective tests, four of 11 (36%) had keratoconjunctivitis sicca, and five of 15 (33%) had pathological sialometry results. In contrast, all PBC patients but one (i.e., 14 of 15 or 93%) showed evidence of focal sialadenitis. In immunochemical study of PBC patients, IgM immunoreactivity was found in the stroma, particularly adjacent to excretory ducts and acini in salivary glands (5 of 5), whereas no such IgM deposits were observed in patients with primary SS (3 of 3), nor in healthy controls (n = 20). We conclude that the frequency of anti-SS-A/Ro and anti-SS-B/La antibodies in serum is lower in PBC patients than in patients with primary SS. The incidence of focal sialadenitis is high in PBC, though only one third of the PBC patients studied here showed clinical evidence of glandular dysfunction. With immunochemical techniques, sialadenitis associated with PBC is distinguishable by its significant IgM reaction from sialadenitis in primary SS.

Abstract
Forty-five patients with primary Sjögren's syndrome were studied for evidence of autoimmune liver disease. Twenty-nine patients had normal liver function tests, normal IgM and a normal test for antimitochondrial antibodies and smooth muscle antibodies. Among the remaining 16 patients, abnormal liver function tests were found in 12 (27% of all patients); eight of these patients had biochemical cholestasis. Elevated plasma IgM (> 2 g/l) was observed in nine patients, three with normal liver function tests, while antimitochondrial antibodies were positive in six patients, one with normal liver function tests, and smooth muscle antibodies were found in three. Based on these findings and percutaneous liver biopsy, a diagnosis of primary biliary cirrhosis was established in four patients and autoimmune chronic active hepatitis in two. The present study showed that abnormal liver function tests in patients with primary Sjögren's syndrome are frequent and may indicate associated autoimmune liver disease. These data further emphasize the systemic nature of autoimmune disorders.

Abstract
Direct immunofluorescence investigation of the skin is an easy and valuable technique to establish the diagnosis immune complex vasculitis. Vascular immune deposits can be found in 60-80% of all cases. Absence of vascular immune deposits, however, does not exclude vasculitis per se, since the dynamics of the vasculitic process limit their presence in time. Knowledge of these dynamics is indispensable for both the clinician and the interpreter. Several practical options are discussed that may increase sensitivity. The specificity of vascular immune deposits has become a complex matter. Different immunoglobulin classes have different specificity, indicating that specificity also depends on the relative incidence of individual immunoglobulin classes. Some of these relative incidences seem to have changed over the years. Furthermore, several non-vasculitic diseases and conditions have now been described, that may show fluorescent pictures similar to vasculitis and thus decrease specificity.

Abstract
Plasma exchange was performed weekly during 6 months in two patients with symptomatic primary biliary cirrhosis. At the end of the treatment period improvement of liver demethylating capacity was noted, along with reduced C3 activation and a decrease in serum concentrations of IgM and procollagen III aminopeptide. Serum concentrations of aminotransferases, alkaline phosphatases, and anti-mitochondrial antibodies were not affected. These data suggest that long-term plasma exchange may improve liver function and possibly retard the progression of fibrosis in primary biliary cirrhosis.

Abstract
Total complement activity was normal in 18 patients with primary biliary cirrhosis using two hemolytic assays capable of distinguishing between defects in classical and alternative pathways. Activation of the classical pathway was demonstrated in all patients by formation of complexes between C1r, C1s, and C1 inactivator. Large amounts of free C1q, not in complex with C1r and C1s, were demonstrated in the majority of patient sera. Furthermore, C4 levels were within the normal range or slightly subnormal. No evidence for alternative pathway activation was found. Increased mean levels of several complement components, in particular C1 inactivator, C2, C3, factor B, factor H, were noted. A significant correlation between these complement factors, derived mainly from the liver, and ceruloplasmin suggests that this elevation might be secondary to cholestasis. In contrast, no significant correlation with levels of early reacting acute phase reactants, immunoglobulins, or circulating immune complex-like material were observed. It is concluded that activation of the complement system by the classical pathway is common in patients with primary biliary cirrhosis.
