RESUMO

Cats naturally infected with the feline immunodeficiency virus (FIV) develop a syndrome that share common characteristics with the human immunodeficiency virus (HIV) infection. For this reason, felines are considered a promising model for the study of HIV infection. HIV associated nephropathy is a common and concerning complication in human beings, resulting in progressive renal insufficiency. Likewise clinico-pathological findings in naturally infected cats suggest a renal involvement. To evaluate the occurrence of chronic kidney disease (CKD) in cats infected with FIV and to verify a possible association between both diseases, a population of 44 cats submitted to the same sanitary handling, diet and exposure to infectious agents was studied. Of these cats, 20 were naturally infected with FIV and 24 were free of FIV infection. Animals were periodically accompanied for a 18-month period through serum creatinine and urinary protein:creatinine ratio measures. The occurrence of CKD in cats infected with FIV was 45%, a value higher than the observed in non-infected cats (25%), but no statistical difference was found. Proteinuria in at least one moment of evaluation was observed in 60% of infected cats and in 26,1% of non-infected cats (p=0,037). Considering the criterion of persistent proteinuria as the observation of urinary protein excretion in at least 3 consecutive moments, infected cats exhibited occurrence of 30,8% compared with 6,7% in the non-infected group (p>0,05). It was observed an association between death and CKD only in the cats infected with FIV (p=0,02). In conclusion, despite occurrence of CKD and proteinuria have not been statistically higher in infected cats than in non-infected one, the association between death and CKD in FIV-infected cats suggests FIV may contribute for the worsening of CKD, resulting in a quicker organic dysfunction and marked reduction of survival.
