Asymptomatic colitis in naturally infected dogs with Leishmania infantum: a prospective study.

A total of 31 dogs with naturally occurring and symptomatic leishmaniasis (Leishmania infantum), but without historical or clinical evidence of overt colitis, were included in this study. With owners' consent, a colonoscopy was performed in all these dogs, revealing patches of hyperemic, edematous, irregular, and mildly erosive colonic mucosa in 25.8% of the animals.

Effects of allopurinol treatment on the progression of chronic nephritis in Canine leishmaniosis (Leishmania infantum).

Forty dogs with canine leishmaniosis (CL) participated in this study, which was designed to investigate the effect of allopurinol on the progression of the renal lesions associated with this disease. The animals were allocated into 5 groups. Group A dogs (n = 12) had neither proteinuria nor renal insufficiency, group B dogs (n= 10) had asymptomatic proteinuria, and group C dogs (n = 8) were proteinuric and azotemic.
