In the last decades, adverse food reactions have increased considerably in dogs and cats. In this study we report on the possible onset of food intolerances symptoms, including otitis, diarrhoea, generalised anxiety, and dermatitis in a cohort of 8 dogs consuming commercial diets. All dogs received an organic chicken-based diet for 15 days. We performed analysis of blood biochemical parameters, kibble composition, and oxytetracycline (OTC) serum concentration before and after 15 days of organic chicken-based diet supplementation. We hypothesised that a chronic intake of contaminated food enhanced by the presence of nanoparticle aggregates might be at the base of the onset of pharmacologic or idiopathic food intolerances. At the end of the evaluation period, an overall significant reduction of otitis, diarrhoea, generalised anxiety, and dermatitis was observed. Biochemical analyses indicate a significant increase in the alkaline phosphatase, from 41 to 52.5 U/L, after 15 days (••p <0.01), while a significant decrease in Gamma-glutamyl transferase and urea, from 9.37 to 6.25 U/L and from 32.13 ± 8.72 to 22.13 ± 7.8 mg/dL, respectively, was observed (•p <0.05). A significant decrease, from 0.22 to 0.02 μg/mL, in mean OTC serum concentration was also observed (••p <0.01). Composition analysis revealed the presence of OTC, calcium, aluminium, silicon, and phosphorous nanoparticle aggregates. Further research on a wider sample size would help to confirm the hypothesis proposed here.
Negli ultimi decenni sono aumentate considerevolmente le reazioni avverse al cibo nei cani e nei gatti. In questo studio si riportano i sintomi da intolleranza alimentare, tra cui otite, diarrea, ansia generalizzata e dermatite, in 8 cani che consumavano regolarmente diete commerciali a base di crocchette. Tutti i cani hanno ricevuto dieta commerciale a base di pollo biologico per 15 giorni misurando, all'inizio e alla fine della valutazione, i parametri emato‑biochimici, la composizione delle crocchette che avevano assunto precedentemente e la concentrazione sierica di ossitetraciclina (OTC). Si è ipotizzato che l'assunzione cronica di cibo contaminato, accresciuta dalla presenza di aggregati di nanoparticelle, potrebbe essere alla base dell'insorgenza d'intolleranze alimentari farmacologiche o idiopatiche. Al termine del periodo di valutazione la sintomatologia clinica è regredita significativamente. Le analisi biochimiche hanno evidenziato un aumento significativo della fosfatasi alcalina dopo 15 giorni da 41 a 52,5 U/L (**p < 0.01), mentre è stata osservata una diminuzione significativa della gamma‑glutamil transferasi e dell'urea, rispettivamente da 9,37 a 6,25 U/L e da 32,13 ± 8,72 a 22,13 ± 7,8 mg/dL (*p < 0.05). L'analisi della composizione delle crocchette ha rivelato la presenza di OTC, calcio, alluminio, silicio, fosforo e aggregati di nanoparticelle. Ulteriori ricerche su un campione più ampio contribuirebbero a confermare l'ipotesi qui proposta.

Abstract
In the last decades, adverse food reactions have increased considerably in dogs and cats. In this study we report on the possible onset of food intolerances symptoms, including otitis, diarrhoea, generalised anxiety, and dermatitis in a cohort of 8 dogs consuming commercial diets. All dogs received an organic chicken-based diet for 15 days. We performed analysis of blood biochemical parameters, kibble composition, and oxytetracycline (OTC) serum concentration before and after 15 days of organic chicken-based diet supplementation. We hypothesised that a chronic intake of contaminated food enhanced by the presence of nanoparticle aggregates might be at the base of the onset of pharmacologic or idiopathic food intolerances. At the end of the evaluation period, an overall significant reduction of otitis, diarrhoea, generalised anxiety, and dermatitis was observed. Biochemical analyses indicate a significant increase in the alkaline phosphatase, from 41 to 52.5 U/L, after 15 days (••p <0.01), while a significant decrease in Gamma-glutamyl transferase and urea, from 9.37 to 6.25 U/L and from 32.13 ± 8.72 to 22.13 ± 7.8 mg/dL, respectively, was observed (•p <0.05). A significant decrease, from 0.22 to 0.02 μg/mL, in mean OTC serum concentration was also observed (••p <0.01). Composition analysis revealed the presence of OTC, calcium, aluminium, silicon, and phosphorous nanoparticle aggregates. Further research on a wider sample size would help to confirm the hypothesis proposed here.File | Dimensione | Formato | |
