ABSTRACT
AIMS:
The aim of this study was to determine the value of urine nerve growth factor (NGF), transforming growth factor beta 1 (TGF-Beta-1), tissue inhibitor of matrix metalloproteinase 2 (TIMP-2) levels to predict the urodynamic profile before and after botulinum neurotoxin type A (BoNT-A) treatment in children with myelodysplasia.METHODS:
This prospective study included 15 children with myelodysplasia who underwent intradetrusor BoNT-A injections due to neurogenic detrusor overactivity (NDOA). Urine samples of each child were collected before and after BoNT-A injections, specifically at the first and third postoperative months. Urine samples were analyzed with ELISA method and NGF, TGF-Beta-1, and TIMP-2 levels were measured. Urine marker levels and clinical findings were assessed for statistical significance with Wilcoxon Signed Ranks Test and Friedman Test.RESULTS:
A total of 15 children (5 boys and 10 girls) were assigned as the study group. Mean age of the patients was 7.1 ± 2.5 years (range 2.5-11). A statistically significantly decline was observed in urinary TGF-Beta-1 and NGF levels following BoNT-A injections, compared to the preoperative levels (P < 0.05). TIMP-2 levels also tend to decrease following BoNT-A injections but this was not statistically significant compared to the preoperative levels.CONCLUSION:
This preliminary study, suggests urinary TGF-Beta-1 and NGF as a potent marker in children with NDOA, as they decline following BoNT-A injection. Further studies are needed in identifying their special role in assessing treatment success after invasive interventions.Palavras-chave
