Complementary alternative medicine in patients with inflammatory bowel disease: use and attitudes.

BACKGROUND: A widespread increase in the use of complementary alternative medicine (CAM) by patients with inflammatory bowel disease (IBD) has been recognized. The aim of our study was to evaluate both the extent and the determinants of CAM use by outpatients with IBD. METHODS: Outpatients of the IBD centre at the University Hospital of Berne and patients of two gastroenterology private practices in Olten (Switzerland) completed a mailed self-administrated questionnaire regarding alternative medicine. The questionnaire addressed the following topics: demographic variables; disease-related data; the use of 16 types of complementary medicine; comparison between attitudes towards alternative versus conventional medicine and out-of pocket expenses. RESULTS: Alternative medicine has been used by 47% of the patients. Diagnosis, duration and activity of disease, gender, age, previous surgery were not predictive for the use of CAM. The most commonly used CAM methods were: homeopathy, acupuncture and traditional Chinese medicine. Reasons cited for the use of CAM were: lack of satisfaction with and side effects of conventional therapy and the perceived safety of CAM. Sixty-one percent of patients noted that their IBD had improved with the use of CAM. By contrast, 16% noted a flare during CAM therapies. Forty-seven percent of patients paid more than Euro400 per year for CAM. CONCLUSIONS: Complementary medicine use is common in patients with IBD. Frequently cited reasons for the use of complementary therapies were safety of CAM; dissatisfaction with conventional therapies, including their side effects; and that CAM can be used in addition to conventional therapy.

Reduced activity of 11 beta-hydroxysteroid dehydrogenase in patients with cholestasis.

Enhanced renal sodium retention and potassium loss in patients with cirrhosis is due to activation of mineralocorticoid receptors (MRs). Increased aldosterone concentrations, however, do not entirely explain the activation of MR in cirrhosis. Here, we hypothesize that cortisol activates MRs in patients with cholestasis. We present evidence that access of cortisol to MRs is a result of bile acid-mediated inhibition of 11 beta-hydroxysteroid dehydrogenase type 2 (11 beta-HSD2), an MR-protecting enzyme that converts cortisol to cortisone. Twelve patients with biliary obstruction and high plasma bile acid levels were studied before and after removal of the obstruction. The urinary ratio of (tetrahydrocortisol + 5 alpha-tetrahydrocortisol)/tetrahydrocortisone, a measure of 11 beta-HSD2 activity, decreased from a median of 1.91 during biliary obstruction to 0.78 at 4 and 8 weeks after removal of the obstruction and normalization of plasma bile acid concentrations. In order to demonstrate that bile acids facilitate access of cortisol to the MR by inhibiting 11 beta-HSD2, an MR translocation assay was performed in HEK-293 cells transfected with human 11 beta-HSD2 and tagged MR. Increasing concentrations of chenodeoxycholic acid led to cortisol-induced nuclear translocation of MR. In conclusion, 11 beta-HSD2 activity is reduced in cholestasis, which results in MR activation by cortisol.

Treatment of hepatic hydrothorax and reduction of chest tube output with octreotide.

Hepatic hydrothorax is a dreaded complication in patients with liver cirrhosis. Placement of chest tubes can alleviate respiratory distress, but patients often succumb due to excessive fluid and protein loss via the open drain. Our case illustrates that high-dose octreotide can strongly reduce hepatic hydrothorax drainage volume. This allows removal of the chest tube, which would otherwise not have been possible.

Cholangiopathy after short-term administration of piperacillin and imipenem/cilastatin.

We describe a patient who suffered from intestinal perforation after abdominal trauma. Perioperatively, he was treated with a single dose of piperacillin and 9 doses of imipenem/cilastatin over 3 days. The patient was discharged 5 days after surgery in good clinical condition and with normal liver values except for a marginal elevation of alanine aminotransferase. Two weeks after discharge, he developed fatigue, fever and pruritus, necessitating rehospitalization. He was jaundiced and had elevated alkaline phosphatase and transaminases. After exclusion of an intra-abdominal fluid collection, a vascular problem, and infectious or autoimmune liver disease, a liver biopsy was performed. The biopsy revealed centrizonal bilirubinostasis, a portal infiltrate rich in eosinophils and cholangitis. Lymphocyte transformation tests for piperacillin and imipenem/cilastatin were positive, suggesting an immunological mechanism for the observed hepatopathy. Cholestasis gradually decreased but was detectable for several weeks. The patient had a full clinical and biochemical recovery after 3 months. We conclude that short-term therapy with piperacillin, imipenem/cilastatin or the combination of these drugs can lead to the same type of hepatopathy as described for amoxycillin/clavulanic acid or antistaphylococcal penicillins. Liver biopsy and positive lymphocyte transformation are compatible with an immunological mechanism.

[Therapeutic use of N-acetylcysteine in acute lung diseases]. / Utilisation thérapeutique de la N-acétylcystéine au cours des agressions pulmonaires aiguës.

Oxidants play a key role in disease processes, particularly in the detrimental mechanisms leading to tissue damage in certain forms of acute lung injury. A number of mediators contribute to the pathologic response in ARDS, SIRS or hyperoxia-induced pulmonary damage. One of the most important detrimental factors is the generation and activation of highly reactive oxygen species which are leading factors implicated in the process of tissue damage. N-acetylcysteine (NAC) is a free radical scavenger and might access the endothelial cell thus increasing intracellular glutathione (GSH) stores. Different studies have demonstrated that NAC might be a promising compound either for the prevention or the treatment of acute lung damages such as ARDS. However, the true beneficial effect so far reported in several clinical and experimental studies contrasts with some contradictory and intriguing aspects, probably because the significance of a direct in vivo antioxidative effect of this compound remains to be established in humans. Thus, the mode of action of NAC may not be the same in different pathologies and clinical situations. More research into the mechanisms of action of this unique xenobiotic substance may offer a clue for elucidating these controversies.

Angiotropic (intravascular) large cell lymphoma: case report and short discussion of the literature.

We report a case of angiotropic (intravascular) large B-cell lymphoma in an 84-year-old woman who underwent diagnostic procedures for progressive, painful induration of the legs. Physical examination and imaging studies revealed only widespread telangiectasias and significant panniculities-like lymphedema of the legs, with no masses or lymphadenopathies. The patient achieved a complete clinical remission after the first three cycles of polychemotherapy. Although angiotropic lymphoma is a rare entity with polymorphic clinical presentations, its early diagnosis appears very important since it may be curable with appropriate chemotherapy regimens.
