An acute pancreatitis in my experience does not normally cause ascites. FIP is a possibility but I would be more interested in looking at causes of a low serum protein. Low protein causes a buildup of fluid in the abdomen and is often associated with a condition called exocrine pancreatic insufficiency. Protein could be lost via the intestine (protein losing enteropathy) or in the urine (protein losing nephropathy).
Thank you very much for your response.
Are you considering nephrotic syndrome then given the sudden onset blindness as well? If so would that be consistent with the ascites - serosanguinous exudate-apologies it had a LOW cell count, not a high one as previously stated? Have read about the connection with glomerular disease and inflammatory condtions like pancreatitis. Now I just heard the cat has tested postitive for it with an fPLI of 15. Have read low albumin was common with pancreatitis but not heard about the connnection with EPI though understandable with lack of enzymes. Do you think this is a possiblity given the increased appetite? Stools were traditionally larger and more tan coloured than other cats, though no diarrhea, ever.
Like the anaemia above, the albumin levels in the past did rise and fall-again with what appeared to be pancreatic flare-ups. Protein did feature in recent urine sample with a UPC of 1.6 though again with the blood difficult to know how accurate this was. However, a strong immunosuppressive of steroid was administered the same week and I've read this can increase urine protein loss. Albumin levels, though below normal weren't alarmingly low ( they were once before with no adverse effects or resultant ascites ) in the same week before this, before the steroid, that is! I will try and find out what the last reading was on presentation though I'd imagine with dehydration it would be higher!
Once again, many thanks for your helpful response!
Forgot to mention the albumin on the day of presentation ( ascites) was 2.1 g/dL and the fluid was also straw coloured. Also renal levels were mildly (2.5 ) increased from last results.
What is the best treatment plan for him?
