Intervención dietético-terapéutica en candidiasis intestinal

Antecedentes: Las candidiasis son infecciones oportunistas producidas por levaduras, cuyo agente etiológico implicado más frecuente C.albicans generando problemas a varios niveles. Caso clínico: Mujer de 39 años diagnosticada de Candidiasis intestinal crónica cursando con sintomatología amplia y variada. Tras la valoración se procede a complementar el tratamiento con una alimentación centrada en la eliminación de azúcares simples, levaduras y productos fermentados. Además, se incluyen ácido caprílico, aceite de orégano y L.acidophylus. Conclusiones: Existe un aumento de la actividad inmunológica acompañada de la mejora sintomatológica.

Therapeutic failure with thalidomide in patients with recurrent intestinal bleeding due to angiodysplasias

Angiodysplasias are one of the reasons of gastrointestinal bleeding, whose origin is usually due to vascular malformations. There are different types of therapies for angiodysplasia such as endoscopic, angiographic and pharmacological techniques. Among the last ones, there is little variety of effective drugs to treat the disease. We describe the therapeutic failure with thalidomide in a male with recurrent gastrointestinal bleeding due to angiodysplasias. A thorough diagnostic work-up, including gastroscopy, enteroscopy, angiography and capsule endoscopy were performed. Despite treatment with high-dose somatostatin analogues and oral iron, the patient continued bleeding. The patient was administered then thalidomide for three months with no clinical response. Thalidomide had to be withdrawn owing to adverse effects.

Role of phospholipase A(2) and tyrosine kinase in Clostridium difficile toxin A-induced disruption of epithelial integrity, histologic inflammatory damage and intestinal secretion

Clostridium difficile-associated disease causes diarrhea to fulminant colitis and death. We investigated the role of phospholipase A(2) (PLA(2)) inhibitors, aristolochic acid (AA), bromophenacyl bromide BPB and quinacrine (QUIN) on the C. difficile toxin A-induced disruption of epithelial integrity, histologic inflammatory damage and intestinal secretion. Toxin A caused severe hemorrhagic and inflammatory fluid secretion at 6-8 h in rabbit ileal segments, an effect that was significantly inhibited by QUIN (71%, P < 0.01), AA (87%, P < 0.0001) or by BPB (51%, P < 0.01). The secretory effect of toxin A was also inhibited in segments adjacent to those with AA (89%, P < 0.01). Furthermore, QUIN or AA substantially reduced the histologic damage seen after 6-8 h in rabbit ileal segments. The cyclooxygenase inhibitor, indomethacin, also significantly inhibited (96%; n = 6) the secretory effects of toxin A in ligated rabbit intestinal segments. The destruction by toxin A of F-actin at the light junctions of T-84 cell monolayers was not inhibited by AA or BPB. AA or QUIN had no effect on the T-84 cell tissue resistance reduction over 8-24 h after toxin A exposure. All the inhibitors were shown to be effective in the doses administered direct in ileal loops to inhibit PLA(2) activity. The data suggest that PLA(2) is involved in the major pathway of toxin A-induced histologic inflammatory damage and hemorrhagic fluid secretion. Cop. right (C) 2008 John Wiley & Sons, Ltd.
