Prognosis for chronic kidney disease in cats
Chronic kidney disease (CKD) and acute decompensation of chronic kidney disease (ACKD) are common in cats.
Researchers evaluated the medical records of 100 cats with confirmed acute decompensation kidney disease. Common clinical signs included anorexia (85%), lethargy (60%), weight loss (39%), and vomiting (27%). Suspected etiologies included ureteral obstruction (11%), renal ischemia (9%), pyelonephritis (8%), others (6%), or unknown (66%).
Hospitalization duration was longer in survivors versus non-survivors, with a survival rate to discharge of 58%. In non-survivors, it was found that age, serum creatinine, urea, and phosphorous concentrations were higher and venous blood pH was lower. Although only serum phosphorus remained associated with the short‐term outcome. Survivors had a median survival time of 66 days after discharge, with serum creatinine concentrations at presentation and at discharge being associated with long‐term survival.
The short‐term prognosis of acute decompensation of chronic kidney disease is comparable to acute kidney injury, while the long‐term prognosis is guarded.
