D‐Lactic Acidosis Secondary to Exocrine Pancreatic Insufficiency in a Cat

Abstract

An indoor, 2‐year‐old, spayed female domestic cat was referred to the University of Missouri Veterinary Medical Teaching Hospital (UMC‐VMTH) for evaluation of weight loss and polyphagia of 1‐year duration, with recent episodes of generalized weakness and lethargy. These episodes occurred approximately once per month over the past 4 months. The cat produced frequent stools, which were occasionally poorly formed. A CBC and serum biochemistry were performed 1 and 5 months before referral, and leukopenia (1,200/μL; reference interval, 3,500‐16,000/μL; no differential provided), hypocholesterolemia (64 mg/dL and 46 mg/dL; reference interval, 75–220 mg/ dL), and hypotriglyceridemia (22 mg/dL and 16 mg/dL; reference interval, 26–160 mg/dL) were identified. The most recent serum biochemistry results disclosed mild hypercalcemia (11.3 mg/dL; reference interval, 8.2–10.8 mg/ dL) and hypernatremia (163 mg/dL; reference interval, 145–158 mg/dL). Antibody titers for Toxoplasma were consistent with past exposure (immunoglobulin M [IgM] negative; IgG 1:256).
