ABSTRACT

Desde o Diabetes Control and Complications Trial (DCCT), a terapia insulínica intensiva tem sido direcionada para alcançar valores de glicemia e hemoglobina glicada (HbA1c) tão próximos do normal quanto a segurança permita. Entretanto, a hiperglicemia (especialmente a hiperglicemia pós-prandial) e a hipoglicemia continuam a ser um problema no manejo do diabetes tipo 1. O objetivo de associar outras drogas à terapia insulínica é diminuir a glicemia pós-prandial. A terapia adjunta pode ser dividida em três grupos, conforme seu mecanismo de ação: 1. Aumento da ação da insulina (metformina e tiazolidinedionas); 2. Alteração da liberação de nutrientes no trato gastrintestinal (acarbose e amilina); 3. Outros modos de ação [pirenzepina, fator de crescimento insulina-símile (IGF-1) e peptídeo semelhante ao glucagon 1 (GLP-1). Muitos desses agentes mostraram, em estudos de curto prazo, diminuição de 0,5 por cento a 1 por cento na HbA1c, diminuir a hiperglicemia pós-prandial e as doses diárias de insulina.


Since Diabetes Control and Complications Trial (DCCT), intensive therapy has been directed at achieving glucose and glycosylated hemoglobin (HbA1c) values as close to normal as possible regarding safety issues. However, hyperglycemia (especially postprandial hyperglycemia) and hypoglicemia continue to be problematic in the management of type 1 diabetes. The objective of associating other drugs to insulin therapy is to achieve better metabolic control lowering postprandial blood glucose levels. Adjunctive therapies can be divided in four categories based on their mechanism of action: enhancement of insulin action (e.g. the biguanides and thiazolidinediones), alteration of gastrointestinal nutrient delivery (e.g. acarbose and amylin) and other targets of action (e.g. pirenzepine, insulin-like growth factor I and glucagon-like peptide-1). Many of these agents have been found to be effective in short-term studies with decreases in HbA1c of 0.5-1 percent, lowering postprandial blood glucose levels and decreasing daily insulin doses.

ABSTRACT

Growth hormone therapy with rhGH (recombinant human growth hormone) has been recommended for treatment of GH deficient short stature in children, repeated hypoglycemias in infancy and early childhood due to GH deficiency, short stature accompanying chronic renal failure prior to renal transplantation and Turner's syndrome. It is now increasingly recommended to adults with GH deficiency following pituitary tumour surgery or irradiation or idiopathic hypopituitarism. There are other indications for its use where evidence for protein catabolism is very strong such as burns injury. The end points of GH therapy in children include achievement of desirable adult height or a growth rate velocity of < 2.5 cm/year. In adults GH deficiency, GH therapy is intended for improvement of general well being, body composition and metabolic markers of GH function.

ABSTRACT

El propósito de la investigación fue evaluar histológicamente los factores de crecimiento (PDGF-BB/IGF-1) como alternativa en la terapia periodontal regenerativa. El estudio se realizó en 3 perros de raza criolla colombiana de 3 a 4 años de edad, de sexo masculino, con enfermedad periodontal inducida con alambre ortodóntico y trauma oclusal con resina. La investigación se realizó en defectos infraóseos, trabajando con un sitio control y un sitio experimental. El sitio experimental se trató con raspaje y alisado radicular a campo abierto y colocación de factores de crecimiento, PDGF-BB/IGF-1, a un volumen de 1 ml., en un vehículo de colágeno insoluble tipo I+PBS. La evaluación se realizó histológicamente a las 8 semanas mostrando que en el 100 por ciento de los sitios experimentales se presentó regeneración periodontal con neoformación ósea, formación de tejido conjuntivo con características de ligamento periodontal y neoformación de cemento radicular, mientras que en los sitios control se encontró reparación de la herida con epitelio largo de unión en un 100 por ciento de los sitios tratados. De los resultados del presente estudio se concluye que los factores de crecimiento, PDGF-BB/IGF-1 son modificadores biológicos con un potencial significativo de regeneración periodontal

ABSTRACT

Primary growth hormone insensitivity produces a clinical picture of severe GH deficiency, but with elevated serum levels of GH as the result of the inability to respond normally to endogenous GH, with absence of feedback suppression of GH release. Since the original description of GH receptor deficiency by Laron and colleagues, only 230 cases have been reported. In this review the authors discuss the clinical and biochemical aspects, the molecular genetic and treatment of this syndrome.

ABSTRACT

Luego de la resección intestinal masiva el intestino remanente experimenta cambios mucosos muy importantes para compensar la remoción de la superficie absortiva. Estos cambios pueden ser disminuidos aportando nutrientes enterales y factores del crecimiento exógenos tales como el IGF-1. La adaptación colónica puede ser aumentada mediante la adición de una mejora en la absorción del intestino delgado. Existe evidencia experimental preliminar de que el aporte intraluminar de IGF-1 produce efectos tróficos directos sobre el intestino delgado, probablemente mediados por mecaniamos paracrinos.
