Autoantibody profiles in microscopic colitis.

OBJECTIVE: The etiology of microscopic colitis is unclear; an autoimmune response and pharmacological induction have been proposed as possible mechanisms. We conducted a multicentre cross-sectional study to compare the antibody profiles of patients with collagenous and lymphocytic colitis with those of a control group. METHODS: The medical histories and antibody profiles of 26 patients with collagenous and 16 patients with lymphocytic colitis were compared with the corresponding data of 43 controls without gastroenterological disease. Antibodies to the following structures were determined: intestinal goblet cells, antinuclear antibodies (ANA), antineutrophil cytoplasmic antibodies, anti-Saccharomyces cerevisiae antibody (ASCA), tissue transglutaminase, gliadin, pancreatic acini, glutamate decarboxylase, tyrosine phosphatase IA-2 and thyroid (microsomal anitbodies, MAB). RESULTS: Patients with collagenous and lymphocytic colitis had been treated significantly more often with H(2)-receptor antagonists and non-steroidal anti-inflammatory drugs (P = 0.026 and 0.014, respectively). Additional diseases of presumed autoimmune etiology were present in 43% (18/42) of patients. Comparison with the controls showed significantly more positive findings for ANA immunoglobulin G (IgG), gliadin immunoglobulin A (IgA) and ASCA (IgA and IgG) in patients with collagenous colitis but not in those with lymphocytic colitis. Collagenous colitis was associated with positive ASCA in 15% of patients and lymphocytic colitis in 13%. CONCLUSIONS: The autoantibodies investigated are of no diagnostic relevance to microscopic colitis. Positive ANA and strong associations with other autoimmune diseases point to an autoimmune etiology. H(2)-receptor antagonists and non-steroidal anti-inflammatory drugs might also be of pathogenetic significance.

Rheumatoid-like nodules in the spleen: new extraintestinal manifestation of Crohn's disease?

A 26-year-old, HLA-B27 positive man with steroid dependent Crohn's disease presented with abdominal lymphadenopathy and multiple abscess-like masses in the spleen and liver 2 years after the initial diagnosis. A biopsy of one of the liver lesions showed epitheloid cell granuloma, no microorganisms were detected despite intensive investigations. The liver lesions and the lymphadenopathy repeatedly disappeared completely in response to prednisolone pulse therapy while the lesions in the spleen remained practically unchanged. One year later, on immunosuppressive therapy with azathioprine and low-dose prednisolone, the patient's condition exacerbated with development of fever, disseminated arthritides and enlargement of the splenic lesions. Following ineffective antimicrobial treatment, a splenectomy was carried out. Histology showed that the splenic parenchyma was filled with abacterial, rheumatoid granulomas. After a renewed flare-up of severe extraintestinal symptoms, the patient is now asymptomatic on immunosuppressive therapy with azathioprine and prednisolone. Abdominal lymphadenopathy is no longer present and the liver lesions are regressing. The intermittent course and the positive response to immunosuppressive therapy point to a further extraintestinal manifestation of Crohn's disease.

Successful photo-and phenobarbital therapy during pregnancy in a woman with Crigler-Najjar syndrome type II.

Severe hyperbilirubinemia in a pregnant mother suffering from Crigler-Najjar syndrome type II is a threat to the unborn child and may result in brain injury. We report the case of a Gly71-->Arg/Tyr486-->Asp homozygous mother of East Asian descent, who was treated with phototherapy during embryogenesis and with phenobarbital during the rest of the pregnancy. This resulted in significantly reduced bilirubin levels in the mother, who gave birth to a healthy boy. A neonatal hyperbilirubinemia resolved spontaneously.
