Title in Portuguese
Efeitos da ciclosporina A sobre a função renal e hepática de cães da raça Golden Retriever normais ou afetados pela distrofia muscular
Keywords in Portuguese
Distrofia muscular animal
Hepatotoxicidade
Imunossupressão
Nefrotoxicidade
Abstract in Portuguese
A distrofia muscular dos cães Golden Retriever (GRMD), uma miopatia degenerativa causada pela ausência da distrofina é geneticamente homóloga a distrofia muscular de Duchenne que acomete humanos, portanto, estes cães são considerados modelos experimentais para estudos em terapia celular. Seu sucesso depende da imunossupressão adequada. A ciclosporina A (CsA) é indicada para tal, a monitorização de suas concentrações sangüíneas e efeitos adversos são essenciais para viabilizar a terapia. Foram estudados cães GRMD, e normais da mesma raça, submetidos a terapia com CsA, associada, nos GRMD, ao transplante. Foram avaliados as concentrações sangüíneas do fármaco e seus possíveis efeitos sobre as funções renal e hepática sendo consideradas as manifestações clínicas relacionadas, urinálise, hemograma, testes de função glomerular, e concentrações séricas de uréia, creatinina, alanina amino transferase (ALT), fosfatase alcalina (FA), cálcio, fósforo, sódio e potássio. Como resultados houve aumento discreto na uréia sérica de ambos os grupos; reações adversas como vômito, diarréia, tricose, periodontite e gengivite; diminuição dos níveis de ALT, cilindrúria e proteinúria e aumento da densidade urinária no grupo dos GRMD. As concentrações séricas de CsA oscilaram muito, em seis dos oito animais. Concluímos que maiores estudos devem ser realizados quanto à função renal dos GRMD e que as doses variam individualmente sendo de maior importância avaliar a concentração do fármaco no sangue e sua viabilização no uso da terapia celular.

Effect of cyclosporin A on renal and hepatic functions of normal Golden Retriever dogs or Golden Retriever with muscular dystrophy

Abstract in English
The muscular dystrophy of Golden Retriever (GRMD) is a degenerative miopaty caused by the absence of dystrophy and it is genetically homologue of the Duchenne muscular dystrophy in humans, so, these dogs are considerably experimental models for studies on cellular therapy. Their successful depends of the adequate immunosuppression. Cyclosporin A (CsA) is indicated for that, the monitoring of the blood concentration and adverse effects are essential to viabilise the therapy. It was studied GRMD dogs, and normal dogs from the same breed, submitted for therapy with CsA, associated, on GRMD, of cell transplantation. It was evaluated blood concentration of the drug, and their possible effects on renal and hepatic functions has been considerate the clinic manifestations, urinalisis, blood counts, testis of glomerular function and blood concentrations of urea, cretinine, alanine aminotransferase, alkaline fosfatase, calcium, phosphorus, sodium and potassium. In our results we found a discrete increase of blood urea on booth groups; adverse reactions like vomits, diarrhea, tricose, periodontitis and gingivitis; decrease of blood alanine aminotransferase, increased levels of urine?s cylinders and protein and also increase of urinary density on GRMD group. The CsA blood concentrations oscillated too much on six than eight of our animals. We concluded that more researches wants to be done to evaluated renal functions of GRMD dogs and also that the doses varieties individually and the correct dosage as to important as the evaluation of the blood concentration of the drug and became viable for cell therapy.
