Abstract
Objective: To describe serum fibroblast growth factor 23 (FGF-23) concentrations in young adult cats with remnant kidney model-induced chronic kidney disease (CKD) and to evaluate the effects of orally administered aluminum hydroxide (ALOH) on serum phosphate and FGF-23 concentrations in these cats.
Animals: 17 adult, purpose-bred cats with induced CKD and 13 healthy, age-matched cats.
Methods: A prospective, randomized study. Cats with induced CKD fed a wet renal diet received treatment with ALOH (90 mg/kg/d, PO) on days 0 to 42 and no treatment on days 43 to 84 (treatment group, n = 9) or no treatment on days 0 to 84 (control group, n = 8). Standard serum and urine biochemical analyses and several parameters reflective of calcium-phosphate balance, including serum parathyroid hormone and FGF-23 concentrations, were evaluated at baseline and various time points, including days 42 and 84. Age-matched, healthy, community-owned cats underwent similar evaluations at a single time point. Baseline data from CKD cats were compared to those of healthy cats. Longitudinal data from CKD cats were compared over time.
Results: Serum phosphate, total and ionized calcium, and FGF-23 concentrations were significantly higher in CKD cats at baseline relative to healthy cats (all P ≤ .009). Serum phosphate concentration did not change significantly over time in either CKD group; however, FGF-23 concentrations significantly increased over time in the control group (P < .02) but not the treatment group (P = .059).
Clinical relevance: Aluminum hydroxide did not reduce serum phosphate or FGF-23 concentrations in this small study of cats with induced CKD chronically eating a phosphate-restricted diet.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
