The effects of up to 240 days of tacrolimus therapy on the gingival tissues of rats – a morphological evaluation

Abstract: Within the limits of the experimental study, it may be concluded that the deleterious side effects of tacrolimus on the gingival tissues of rats may be time-related.

“…The exact mechanism of Tcr‐induced GO during long periods of treatment is not known. In a study by Nassar et al, 27 it was speculated that GO could result from a gradual sensibilization of gingival fibroblasts as well as of the gingival epithelium. Long‐term Tcr therapy may have a direct or indirect action on fibroblasts or in determined populations of gingival fibroblasts as well as on collagen metabolism via cytokines, growth factors, and the consequent activity of tissue inhibitor of matrix metalloproteinase.…”

“…[2432] Various studies have demonstrated less frequent association of gingival overgrowth with the use of tacrolimus than with cyclosporin. [3334] Synergistic effects have been reported when cyclosporin is administered concurrently with calcium channel blockers of dihydropyridine derivatives. [35]…”

“…Os ratos têm sido amplamente utilizados para estudar os efeitos de drogas na gengiva, e o crescimento gengival é semelhante ao dos humanos. A utilização deste modelo tem permitido o controle rigoroso de algumas variáveis importantes, tais como predisposição genética, idade, dose e via de administração de drogas, por consequência a resposta em ratos é mais uniforme do que nos seres humanos 20 . Os resultados desse estudo (Tabela 2), não demonstraram uma associação entre o efeito da obesidade e o crescimento gengival, uma vez que somente os grupos com periodontite induzida apresentaram crescimento gengival, o que efetivamente pode ser atribuído à presença da doença periodontal experimentalmente instalada.…”

“…Ao nascimento, os filhotes foram separados por sexo ficando 6 machos para cada ninhada, perfazendo um total de 24 animais, cálculo baseado em prévios estudos 15,17,20 , esses foram desmamados com 21 dias, então, receberam dieta padrão e água á vontade por todo o período experimental. Todos os protocolos experimentais foram aprovados pelo Comitê de Ética em Experimentação Animal e Aulas Práticas (CEEAAP) da UNIOESTE, com protocolo em 09/04/2013.…”
