Medicinal mushrooms have demonstrated various pharmacological properties due to the numerous compounds in their mycelial structures, that can act in a synergistic or non-synergistic manner to treat different diseases and conditions. In this study, the Auricularia fuscosuccinea (AF), recognized for its high fiber content, protein, amino acids, low glucose levels and no toxic effects, was administered to rats with Type 2 Diabetic Mellitus (T2DM) and diabetic kidney disease (DKD) in order to evaluate its impact on renal function.  Objective: evaluate the  renoprotective effect of the AF in DKD in rats.

Adult Wistar rats were divided into three groups: Control- vehicle (0.1M citrate buffer, 60mg/kg, i.p.); T2DM - T2DM induction (nicotinamide, 100mg/kg, intraperitoneal, i.p. + streptozotocin, diluted in 0.1M citrate buffer, 60mg/kg, i.p., once). and T2DM+AF - Auricularia fuscosuccinea (AF, 100mg/kg, diluted in 1mL of drinking water, orally, once a day, 30 days) in T2DM rats. Evaluation of renal function by serum creatinine and inulin clearance (Clin) and oxidative profile by urinary peroxides (FOX), thiols and catalase were evaluated.

The treated group, T2DM+AF, presented a reduction in serum creatinine (0.29±0.03 vs 1.02±0,30, p<0.05) and an increased inulin clearance (0.79±0.50 vs 0.30±0.03, p<0,05) compared with the T2DM group. Also, the oxidative profile of the T2DM+AF group showed a reduction in urinary peroxides (0.11±0.20 vs 12.0±1.8nmol/g creat, p<0.05)  and elevation in the thiol (18.9±6.0 vs 1.6±0.6 nmol/g, p<0.05) and catalase levels (6.72±1.39 vs 0.40±0.01 umg/ml, p<0.05) compared with T2DM group.

This is the first study to point out the therapeutical properties of the amazonian mushroom Auricularia fuscosuccinea (AF). The oral administration of AF showed renoprotective effects in renal function and attenuation of the oxidative damage, confirming its antioxidant properties in the DKD. Our findings demonstrate that consuming AF daily shows additional beneficial effects in the treatment, protecting renal function from the insults of the T2DM. Further studies are needed to assess long-term outcomes regarding its new product.
