HISTIOCYTIC ULCERATIVE COLITIS - A SPECIAL FORM OF COLITIS
This condition is also called "Boxer Colitis"
(WHAT?!) because the Boxer breed seems predisposed. This form of colitis is particularly ulcerative
(SUPER... "particularly ulcerative"...) and involves infiltration of the tender colon lining with cells called "histiocytes." These cells are the cells that are normally called into the scene of inflammation relatively late so that they can absorb the dead cells and debris that have been created by the inflammatory event.
Dogs with this condition typically show symptoms at an early age (less than 2 years)
(DAMMIT! Copper qualifies!) and become more debilitated by their symptoms than the usual colitis patients do
(NO KIDDING). It is currently believed that this condition results from an inappropriate immune response against the common bacteria of the colon. Dogs with this form of colitis do not respond well to the usual remedies but instead seem to show an excellent response to the antibiotic enrofloxacin.
Histiocytic ulcerative colitis can be confirmed by biopsy though signs of colitis in a young Boxer are highly suggestive of this condition (
AND MY BOXER HAS IT -- BOO!).
Don't mean to gross you out, Avid Reader, but indeed Histiocytic Ulcerative Colitis has likely descended on the Moore household. Poor Copper is el-sicko and has been for the past week. She was having VD (volcanic diarrhea) as of last weekend and blood began to show in her stool as of last Monday. She started a couple of meds this week that only stablized the condition, but it never improved. After some blood-free samples, Copper took a turn for the worse today and I took her in only to have more probing (Copper took it like a champ!), more meds and her first x-rays. We're on what I call "horse meds" now as she's getting Clydesdale doses of anti-bacterials now. But more white rice/cottage cheese meals, runny diarrhea, and colon challenges for Copper. Cross your fingers she improves for her first birthday party in three weeks!
