Chronic Purulent Draining Tracts In A Dog
by fdzenitsky - January 29, 2025    View Case Report
Hi Steve,

Betsy, a very nervous and thin 9YO SF terrier mix, presented last fall w/ chronic draining tracts from a ruptured anal gland of ~4 years duration. Chronic abscess in the right caudodorsal lumbar soft tissues with a draining tract that extends to the level of the anus with extensive abnormal tissue changes along her right anus/rectal region and lower back/right hip region. The caudal draining tract bifurcates, with one portion extending to the anus and another along the proximal right pelvic limb Incidental CT findings include cholelithiasis and multiple nephroliths. She has a long-term history of Apoquel, since a puppy, for seasonal allergies but was on it all year-round until I weaned her off. History of sarcoptic mange, recurrent otitis, dermatitis... She also reacts poorly to vaccinations and parasite preventatives (lethargy and severe diarrhea) , she is an immune-compromised hot mess!! w/ little benefit when I started her on a raw diet w/ ample fermentable carbs.

My initial Dx: Damp Heat, invading Wind Heat pathogens, Wei Qi, Blood deficiency and Stasis. For all her -itis, chronic inflammation, infected fistula, and associated draining tracts, I found her to be very deficient back in August w/ a pale muddy T and thin, toneless P, and thought she was not strong or Hot enough for XFHMY, so began BYHWT instead along w/ 2 drops K Iodide, and silver sulfadiazine augmented with essential oils to infuse in the tracts every few days. This did little to resolve the skin but did tone her still deficient P, T still pale and muddy, so in Nov., I started a course of cefpodoxime and changed herbs to XFHMY. Some, but not significant improvement was seen and now I've made her Cold. Overall, not doing well this month, spends most time under blankets or by the fireplace, had a bout of constipation, draining tracts still open w/ a whitish discharge (that increases w/ stress), and a few raised skin areas on the right hip where new tracts may be threatening to open up. Great appetite, maybe her only joy these days.

I don't see Damp Heat anymore, just Deficiency w/ Stasis, sure SYD, causing her excess skin - or is it rather a deficient skin issue? I am at a loss...the formulas I think will most help resolve this chronic skin issue are too cooling for her constitution so I feel damaging, not a good fit. I am considering QYT next, again it's very cooling. But what if I added herbs to the formula to warm her up or does that defeat the formula's intended use? Can I use CHSWT and QYT in tandem and cover the bases or is there another approach you can suggest? I really want to help this little dog, she has been through so much her entire life and her people are committed, doing all I ask of them.

I'm rechecking her this week, so fingers crossed you can weigh in soon. Many thanks as always! Franchesca

Hi Franchesca,

I think you were close with your initial choices. I'd wonder about Bu Zhong Yi Qi Tang, since it helps expel pathogens, when paired with a Wind dispersing formula; addresses a worsening during stress (because it is an adaptogen); tonifies the Spleen and counters tendencies to collapse (revealed by the reaction to ectoparasiticides); helps resolve infections (by enhancing Wei Qi); and is especially called for in animals that worsen in deep winter.

Note that chronic Apoquel use is notorious for depleting Wei Qi, which usually manifests as that flaccid empty pulse you felt. Wei Qi was viewed to be what gives the pulse tone, helping the vessel contract down around the blood column, which fills up the vessel. It is an alternation of the two - the filling pressure of Ying Qi and the constricting of Wei Qi - which was viewed to create the pulse. Not the heart.

If you try BZYQT, you could pair it with something warming that combats infection like Chu Shi Wei Ling Tang, but see what it does on its own first. It might even allow you to use the Xian Fang Huo Ming Yin again. Other alternatives include Modified Xue Fu Zhu Yu Tang or even Xiao Huo Luo Dan, since persistent lesions always indicate Blood stasis. You would resort to them if the first two suggestions don't bear fruit.

Lastly, I would suggest homeopathic Silicea once or twice a day (I use 30C strength) since the nature of the discharge and the general lack of vigor of the patient are a good fit for it helping to oust the infection. I'd get that started with the BZYQT right off the bat, while you're pondering how best to move Blood and expel the pathogen using one of the four suggestions mentioned above.

Hopefully this helps. It's an odd case! Let us know how it goes

Steve
