FIV-infected cats respond to short-term rHuG-CSF treatment which results in anti-G-CSF neutralizing antibody production that inactivates drug activity

Abstract: The hematological and virological effects of recombinant human granulocyte colony-stimulating factor (rHuG-CSF) were evaluated in feline immunodeficiency virus (FIV)-infected cats. Six age-matched, FIV-infected cats used in this cross-over study were injected subcutaneously with 5 microg/kg of rHuG-CSF daily for 3 weeks, while six control cats received a placebo. Five of six rHuG-CSF-treated cats had significant increases in neutrophil counts that peaked on days 11-21 of treatment. All rHuG-CSF-treated cats ex… Show more

“…231 Interferons, both human and feline origin, have also been used in FIV-infected cats. Cytokines, such as granulocyte colonystimulating factor (G-CSF) and erythropoietin have been used to stimulate blood cell production in cases of neutropenia and anemia, respectively.…”

“…Seu uso foi sugerido no tratamento de gatos com neutropenias associadas a FIV e FeLV, porém ainda está sob estudos (SHELTON & LINENBERGER, 1995;HENRY et al, 1998). PHILLIPS et al (2005) demonstraram que o tratamento com o fator estimulante de colônia de granulócitos recombinante humano em gatos infectados pelo vírus da FIV aumentou o número de neutrófilos circulantes destes animais.…”

“…Os fatores de crescimento hematopoiético espécie-específicos raramente induzem o desenvolvimento de anticorpos, porém o uso de rhG-CSF, uma proteína recombinante humana, por semanas consecutivas em cães e gatos, pode induzir a formação de anticorpos contra o medicamento, neutralizando sua ação e fazendo com que os neutrófilos voltem aos valores de normalidade (HAMMOND et al, 1991;PHILLIPS et al, 2005). Tratamentos mais prolongados podem induzir a formação de anticorpos contra o G-CSF nativo do animal, por meio de reação cruzada.…”
