Effects of diclofenac and dexamethasone on horse experimental endotoxemia

Abstract: Fifteen healthy Mangalarga horses, aged two to three years were used to evaluate the possible beneficial effects of dexamethasone and sodium diclofenac administration during experimental endotoxemia in horses. They were divided into three groups with five animals each: control (C), sodium diclofenac (SD) and dexamethasone (DM). All groups were given 0.1µg of Escherichia coli O55:B5 endotoxin/kg of body weight, intravenous, over 15 minutes, and one of the following preparations: group C - 20ml of 0.9% saline in… Show more

“…This effect is presumably caused by the synthesis and release of pro-inflammatory substances, which could inhibit the normal gastrointestinal muscular activity, reduce the threshold for painful stimuli, and/or reduce gastrointestinal blood flow. As a consequence of these possible effects of LPS, it may be surmised that endotoxaemia can increase the likelihood that a donkey Some in vivo experiments have been conducted in horses and ponies using physiological amounts of E. coli O55:B5 endotoxin at doses of 20-30 ng/kg (Moore et al 2007;Toth et al 2008;McGovern et al 2013;Watts et al 2014) or 0.1 µg/kg (Rosa et al 2003), which were given via slow i.v. infusion.…”

“…De fato, no estudo clínico realizado por Rosa et al (2003), empregando esses mesmos eqüinos, o aumento da atividade da citocina descrita, foi coincidente com aumento da temperatura retal e a redução dos movimentos intestinais entre 1h15min e 6h após indução da endotoxemia, estando associada à leucopenia com neutropenia e linfopenia.…”

“…Segundo Rosa et al (2003), a ausência de febre nos animais que receberam dexametasona neste experimento pode ter ocorrido pela diminuição ou inibição da produção de PGE 2 e, ainda, pela inibição da síntese de TNF-α (Morris et al, 1991). A dexametasona reduz a transcrição do gene TNF e a tradução do TNF RNAm (Beyaert e Fiers, 1998).…”
