[A case of Crohn's disease associated with ankylosing spondylitis and digital hippocratism].

Some comments are made on the association of chronic intestinal inflammatory conditions and articular manifestations on the basis of a case of Crohn's disease associated with ankylosing spondylitis and digitalic hippocratism. The clinical case is described and the literature on associations observed during Crohn's disease reviewed. Special attention is paid to associations involving ankylosing spondylitis, enteropathic synovitis and hypertrophic osteopathy, particularly as regards the presence of clubbed fingers.

Eradication of esophageal varices by endoscopic sclerotherapy: how much is enough?

To clarify if complete eradication of varices from the lower esophagus by endoscopic sclerotherapy is really essential to prevent rebleeding, or if reduction of varices below a certain size can be considered a sufficient result, we compared the fate of 72 patients in whom sclerotherapy was stopped after one of the following endoscopic endpoints was reached: complete eradication (15 patients, group 1), partial eradication with residual small white varices (32 patients, group 2), and partial eradication with residual small blue varices (25 patients, group 3). The incidence of variceal recurrences and recurrent bleeding over a median follow-up of 17 months after stopping sclerotherapy did not differ significantly in the three groups. Analysis of the time course of variceal recurrences showed that the recurrence-free interval was almost identical in group 1 and group 2 patients (13 and 14 months, respectively). Group 3 patients had a shorter recurrence-free interval (8.3 months), but the difference was not statistically significant. We conclude that sclerotherapy can be stopped safely when either complete eradication or reduction of varices to small white columns is obtained.

[T-cell interferon-gamma, tumor necrosis factor-alpha and interleukin-6 receptor binding in patients with multiple sclerosis. Effects of interferon-beta-1b treatment].

INTRODUCTION: Multiple sclerosis (MS) is a T-cell-mediated demyelinating disease of the central nervous system (CNS), in which the cytokine network may be deranged. Interferon (IFN)-gamma, interleukin (IL)-6, and tumor necrosis factor (TNF)-alpha are cytokines with several effects on the neuroimmune system. Specific IFN-gamma, IL-6, and TNF-alpha receptors have been found on human lymphocytes and other cell types. PATIENTS AND METHODS: We assayed IFN-gamma, TNF-alpha, and IL-6 binding on peripheral blood T cells from MS patients, as compared with healthy subjects. T cells from MS patients have significantly less IFN-gamma receptors, and more TNF-alpha and IL-6 receptors than those from controls. Such receptors are of the same type in patients and healthy subjects. By comparing MS patients' subgroups with each other, significant differences in mean Bmax values have been found between patients in a stable phase and those in relapse, and between stable patients and those in an evolutive phase. As far as IL-6 binding is concerned, significant differences in mean Bmax values were observed only between patients in stable phase and those in relapse. RESULTS: T lymphocytes from untreated MS patients, which had significantly smaller amounts of IFN-gamma receptors than those from controls, and more TNF-alpha and IL-6 receptors than controls showed a significant increase in IFN-gamma binding, and a significant decrease in TNF-alpha and IL-6 binding after a 3-month IFN-beta 1b treatment. T-cell IFN-gamma Bmax values were even higher, and those of TNF-alpha and IL-6 were lower after 6 months. CONCLUSION: We discuss these results in terms of MS immunopathophysiology, since activated T cells have decreased IFN-gamma, and increased TNF-alpha and IL-6 receptor amounts.

[Amyotrophic lateral sclerosis with multiple myeloma].

Motor neuron diseases (MND) associations with paraproteinemia, lymphoma, hexosaminidase A deficiency and heavy-metal intoxication are of great interest. A case of amyotrophic lateral sclerosis (SLA) associated with multiple myeloma (monoclonal IgG paraproteinemia and K light chains) is reported. The detection of abnormal protein in 1988 and the increase of its serum level during 1989 were strictly correlated with the beginning and the worsening of the neurological disease. Shy and coll. in 1986 affirmed that association of paraproteins with MND is probably not merely the fortuitous association of a common laboratory abnormality and an uncommon disease. The reported case provides elements for a causal association between paraproteinemia and MND.

Clinical course of inflammatory bowel disease during treatment with interferon for associated chronic active hepatitis.

Seven patients with inactive ulcerative colitis and seven patients with Crohn's disease (5 inactive, 2 mildly active) received interferon treatment for associated chronic active hepatitis. Neither relapse (except in one patient) nor worsening of the clinical course of the inflammatory bowel disease was observed during treatment. According to these results chronic active hepatitis associated with inflammatory bowel disease can be treated with interferon without the risk of deteriorating the course of the inflammatory bowel disease.
