Out of 210 cases of ulcerative colitis 41 had skin and mucosal lesions: skin lesions in 23 (11%), oral ones in 11 (5.2%) and perianal in 16 (7.6%). Cutaneous lesions were: maculopapular rashes (5.2%), erythema nodosum (2.9%), pyoderma gangrenosum (1.4%), papulopustular lesions, vasculitis and erythema multiforme (1% each). Aphthae were the commonest oral complication (4.3%) and fissures and fistula the more prevalent perianal ones (4.3% and 3.4%). More than one mucocutaneous complication occurred in 17.1% of the patients and in 18 patients there were associated articular (36.6%), ocular (9.8%) and hepatic (2.4%) changes. The colitic type of arthritis and keratoconjunctivitis sicca were the commoner joint and eye manifestations.

Primary sclerosing cholangitis and primary biliary cirrhosis are chronic cholestatic syndromes that may be difficult to differentiate clinically. Destructive cholangitis occurs in both diseases and leads to similar clinical and biochemical abnormalities. Therefore, we compared the clinical, biochemical, immunologic, radiologic, and hepatic histologic features of these syndromes in two large groups of patients prospectively selected by predefined criteria. Primary biliary cirrhosis (n = 258) occurred predominantly in middle-aged women who were usually symptomatic with fatigue and pruritus, commonly had keratoconjunctivitis sicca, and often were hyperpigmented. Tests for antimitochondrial antibodies were always positive, usually in very high titer. Although the extrahepatic bile ducts were normal radiographically, smooth tapering and narrowing of the intrahepatic bile ducts was occasionally noted. Hepatic histology was diagnostic when a florid duct lesion was present. In contrast, primary sclerosing cholangitis (n = 60) occurred primarily in young men who were usually symptomatic with fatigue and pruritus and frequently had chronic ulcerative colitis. Tests for antimitochondrial antibodies were nearly always negative and cholangiography demonstrated abnormalities of the extrahepatic and intrahepatic bile ducts in all cases. Although hepatic histology was often compatible with the diagnosis, it was usually not diagnostic, and considerable overlap existed with the abnormalities seen in primary biliary cirrhosis. Likewise, biochemical tests of copper metabolism were similar in both syndromes. These results call attention to the differences and similarities in the clinicopathologic features of these two cholestatic syndromes and provide a basis for a rational diagnostic strategy.

Cyclosporine is a potent immunosuppressant used in the treatment of ulcerative colitis and keratoconjunctivitis sicca. Neither the etiologies of these diseases nor the mechanism by which cyclosporine exerts its therapeutic effect is well understood. Since both diseases are linked by a common decrease in mucin-filled goblet cells, this study tests a hypothesis that cyclosporine acts directly on goblet cells to promote their differentiation and production of secretory mucins. The HT29-18N2 human colon adenocarcinoma cell line, which is capable of forming monolayers of well-differentiated goblet cells, was used as a model system. Cyclosporine induced a dose-dependent increase in intracellular mucin stores. A 2-week exposure to 1 microM cyclosporine resulted in an average increase in mucin volume of 94%. This increase resulted from both a higher percentage of cells with mucin stores and an increased volume of mucin per cell. PSC-833, a nonimmunosuppressive analog of cyclosporine, also increased mucin production. The intracellular accumulation of mucin was not a result of reduced secretion, since the time required for the release of pulse-radiolabeled glycoproteins was similar for both control and cyclosporine-treated monolayers. The effect of cyclosporine was not mediated by the drug's previously documented abilities to decrease cellular proliferation rates, inhibit calmodulin, antagonize prolactin receptor binding, or modulate prostaglandin production.

We aimed to investigate the frequency of rheumatic diseases in patients suffering from autoimmune thyroid diseases (ATD). Sixty-five patients (56 F, 9 M), who were followed by diagnosis of ATD, were questioned and examined for the presence of rheumatic disease. Basic laboratory tests and antithyroid antibodies, antinuclear antibody and rheumatoid factor (RF) levels were also measured by appropriate methods. Various rheumatic diseases were detected in 40 (62%) of patients with ATD. The most frequent rheumatic conditions were fibromyalgia, recurrent aphthous stomatitis, osteoarthritis, keratoconjunctivitis sicca and xerostomia and carpal tunnel syndrome which were detected in 20 (31%), 13 (20%), 10 (15%), 9 (14%) and 8 (12%) of patients, respectively. Autoimmune diseases, except Sjogren's syndrome, which were detected in ten patients with ATD, are as follows-vitiligo: two; autoimmune hepatitis: two; oral lichen planus: one, ulcerative colitis: one, inflammatory arthritis in four patients (two of them had rheumatoid arthritis, one had psoriasis and psoriatic arthritis and one had mixed collagen tissue disease). RF was positive in two patients, one of them had rheumatoid arthritis and FANA was positive in six (9%) patients; all of them had hypothyroidism. The frequency of rheumatic diseases seems to be higher in patients suffering from ATD. Initial evaluation and a regular checking for rheumatic diseases in patients suffering from ATD were recommended.
