In contrast to extensive studies on insulin resistance and impaired glucose homeostasis in humans with chronic kidney disease (CKD), there is a lack of research addressing these metabolic alterations in cats with CKD. Understanding the metabolic changes associated with CKD in cats is essential for effective clinical management and for enhancing our knowledge of the disease's pathophysiology. Therefore, this study aimed to evaluate insulin secretion, glucose concentrations and homoeostasis model assessment of insulin resistance (HOMA-IR) in non-diabetic cats diagnosed with stage 3-4 CKD.</p><p><strong>Methods: </strong>Ten clinically healthy cats (healthy controls) and fifteen non-diabetic cats with CKD) were included in the study. Fasting blood glucose, insulin, urea, creatinine, phosphor, calcium, sodium, chlorine, potassium, albumin and total protein levels were analysed in all the patients.

Cats with CKD exhibited significantly lower serum insulin concentrations (6.05 ± 2.45pg/mL) compared to healthy cats (19.08 ± 5.01pg/mL; p < 0.001). Glucose concentrations in cats with CKD (149.89 ± 61.49) were notably higher than those in healthy controls (93.02 ± 7.39; p < 0.001).

Trichophyton mentagrophytes, a common dermatophyte, often resists standard antifungal therapies, necessitating alternative solutions. Eugenol, a natural compound with potent antifungal properties, has gained attention for its synergistic effects with conventional antifungal agents. However, its clinical application is limited by poor bioavailability and stability. Nanoencapsulation of eugenol offers a promising strategy to enhance its antifungal efficacy and address these limitations. This study aims to evaluate the antifungal efficacy of eugenol and nanoencapsulated eugenol in combination with Itraconazole against T. mentagrophytes isolates.</p><p><strong>Methods: </strong>Eugenol-loaded nanocapsules were fabricated using the nanoprecipitation method and subsequently evaluated. The antifungal activity of eugenol, nano-eugenol and Itraconazole-individually and in combination-was assessed against clinical isolates of T. mentagrophytes derived from animal and human sources, using minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) determinations. The chequerboard assay evaluated the synergistic effects.</p><p><strong>Results: </strong>Scanning electron microscopy (SEM) and dynamic light scattering (DLS) analyses showed that eugenol nanocapsules have a uniform, spherical morphology with an average size of 150.9 nm and moderate polydispersity (polydispersity index [PDI] = 0.531), whereas a slight negative zeta potential (-0.1 mV) contributes to suspension stability by minimizing aggregation. The geometric mean MIC of eugenol was 119.3 µg/mL, significantly lower than that of nano-eugenol (477.4 µg/mL), whereas Itraconazole had the lowest MIC at 11 µg/mL.

Combining Itraconazole with nano-eugenol showed synergy in 73.3% of T. mentagrophytes isolates, reducing Itraconazole's MIC by up to 1/2 or 1/4.
