Comparative Clinical Efficiency of Resveratrol, Allopurinol, and Resveratrol Plus Allopurinol in Canine Visceral Leishmaniasis
(American Veterinary Medical Association, 2025) Erdogan, S.; Erdogan, H.; Ural, K.; Pasa, S.; Gultekin, M.; Balikci, C.; Gunal, I.
Objective To assess the clinical and immunological effectiveness of resveratrol alone or combined with allopurinol for treating canine visceral leishmaniasis (CVL). Methods This study included 50 dogs, 30 diagnosed with CVL and 20 healthy controls. Dogs were classified based on their treatment regime (receiving resveratrol [200 mg/dog/d] and/or allopurinol [10 mg/kg/d]). Clinical scores, anti-leishmanial antibody titers, and routine blood parameters were evaluated on days 0, 15, and 30 after treatment. Results Dogs treated with the combination therapy showed the most substantial improvements, with a 75.77% reduction in clinical scores and an 81.25% reduction in antibody titers. Dogs receiving allopurinol exhibited a 56.25% reduction in clinical scores, while those treated with resveratrol showed a 42.82% reduction. Antibody titers were less significantly reduced in the resveratrol group (67.5%) compared to the allopurinol group (45%). Conclusions Combining resveratrol with allopurinol enhances the therapeutic efficacy for CVL, leading to significant clinical improvements and reductions in antibody titers. Resveratrol alone also demonstrates promising anti-leishmanial effects. Clinical Relevance Resveratrol, either alone or in combination with allopurinol, offers a feasible and effective alternative for improving clinical outcomes in CVL. Its incorporation into standard protocols may enhance treatment strategies in veterinary medicine. ©The authors.
Effect of Curcumin Enema Dosage Regimes on the Reduction of Giardia Cyst Among Calves
(Pusat Penelitian Dan Pengembangan Peternakan, 2023) Ural, K.; Erdogan, H.; Ural, Da; Pasa, S.; Erdogan, S.; Ayan, A.; Balikci, C.
Giardiasis is one of the most significant and neglected parasitic infestations among calves, resulting in intestinal infections. This protozoan agent gained diagnostic and therapeutical importance because of its zoonotic potential, in which novel alternative/substitute therapeutical interventions are important, and this is because commonly used anti-parasitic drugs for control and eradication for battling this infection commonly presented side effects. Therefore, the present project evaluated the antiprotozoan activity of curcumin at different dose regimes used via the rectal route, the main constituent of turmeric. Rectal enema groups [Group I: 2 gr/kg, Group II: 80 mg/kg, and Group III: 10 mg/kg] and oral treatment Group IV: 2 gr/calf consisted of curcumin treatment at appropriate dosages showed herein in which the control group V were untreated. All treatment groups showed a statistically significant decrease in cyst counts on day 10, compared to day 10 values of the control group (p<0.005). Among the treatment groups, the highest cyst reduction was evident at 99.86% in curcumin 10 mg/kg rectal enema-administered calves (Group III), which received the lowest dose of the study. Curcumin at all dosages, primarily used in the rectal route at the lowest dosage regimen of 10 mg/kg, could have hastened clinical and parasitological efficacy via probable inhibition of Giardia proliferation and adhesion, as described previously. This treatment modality via the rectal route can change the game, highlighting novel treatment protocols.
