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.

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.

The Glu23Lys polymorphism in KCNJ11 and impaired hypoglycaemia awareness in patients with type 1 diabetes.

Impaired awareness of hypoglycaemia affects approximately 25% of all patients with type 1 diabetes (T1D). Duration of diabetes and tight glycaemic control represent the main risk factors for hypoglycaemia unawareness. However, even among patients with good glycaemic control and longstanding T1D, awareness of hypoglycaemia may be intact.
