FIV and Chronic Diarrhea
1. Background

3. Treatment Options
1. Background
According to one set of published statistics, 10-20 % of FIV+ cats have chronic or recurrent
diarrhea as a symptom of their infection [1], placing it behind oral disease, upper respiratory
infection, and eye infection in order of occurrence. No definitive explanation exists for the frequency of FIV-related diarrhea. In one study of 10 FIV+ cats with chronic diarrhea, a specific pathogen could be
isolated from only one [2]. So unless the tests used to isolate pathogens are inadequate, there is
something about FIV infection that predisposes cats to diarrhea. One classic source writes as
follows:
FIV-infected cats with chronic diarrhea and wasting often show a characteristic severe
and diffuse villous atrophy that is particularly evident in the lower half of the small
intestine, and focal areas of mural necrosis with fibrosis in the wall of the intestine.
Lymphoid tissue within the intestinal wall is often hyperplastic with pronounced increase
in the number of B lymphocytes and plasma cells. Intestinal lesions are reminiscent of
those caused by acute panleukopenia virus [feline parvovirus] infection, but they are
chronic rather than acute in nature. [2b]
Experience with chronic diarrhea in HIV-infected humans and SIV-infected primates may point
to a role for direct action of the virus upon gut tissue as a component (a disproportionate number
of HIV relative to the rest of the body inhabit this tissue). Studies have found that GI symptoms that include diarrhea improve significantly as soon as one week after antiretroviral drugs are begun, suggesting that the virus itself has a central role in the GI tract pathology; it is possible, therefore, that any therapy having a significant impact on FIV viral load might have some impact on FIV-related bowel problems. However, an inflammatory immune response is almost certainly involved, as well. One recent source speculates, “IL-6 [interleuken-6] is an important proinflammatory cytokine that is believed to enhance HIV replication and is also up-regulated in
several chronic inflammatory conditions such as inflammatory bowel disease, rheumatoid
arthritis, and numerous neoplastic conditions . . . . In the GI tract, both primary HIV/SIV
replication and the cytokines/chemokines elaborated thereafter by inflammatory cells have the
potential to activate several signal transduction pathways. Activation of these signaling pathways
secondary to virus infection may interfere with the homeostatic signaling events required to
maintain normal GI structure and function, thereby leading to compromise of the intestinal
barrier. Although the etiology of chronic diarrhea in HIV-infected patients remains complex,
proinflammatory cytokine networks may be expected to play a central role.” [19].
A clue to approaching the problem may lie in the areas of similarity between ideopathic
inflammatory bowel disease and another common inflammatory disease seen in FIV+ cats,
chronic stomatitis/gingivitis. The latter:
■ occurs in FIV-cats, but has a stronger statistical association with FIV+ cats.
■ includes predominating lymphocytic-plasmacytic* cellular infiltrates in biopsied mucosal
tissue
■ has been theorized (in the case of L-P) to involve disturbance in local lymphocyte
populations, which show a shift from a predominant CD4+ Th1 profile to a mixed
Th1/Th2 profile.
■ is believed to involve sensitivity to certain food components–whether additives,
carbohydrates, or certain types of meat products or byproducts is not clear and may vary
from case to case.
■ involves a probable interaction between or cumulative action of other alien antigens and
FIV.
All except the last have been ruled in with regard to chronic inflammation of the large and/or
small bowel, and evidence is accumulating for the last [2a].
*Some IBD may be eosinophilic or granulomatous in nature; so, for that matter, may oral lesions.
However, in both cases, lymphocytic-plasmacytic is most common.
2. Types of Diarrhea
“Simple” Diarrhea. An adult cat can be given 24-48 hours to sort out an episode of diarrhea
that may have been sparked by dietary factors or other transient influences, such as stress.
However, if the diarrhea is bloody, black, or mucus-laden or if it is accompanied by pain,
excessive straining, fever, recurrent vomiting, or depression, a vet should be contacted
immediately. Extra caution should always be exercised with kittens (especially those that have
not yet received vaccinations), who can dehydrate rapidly. Attention to hydration (and
rehydration, if necessary, with lactated Ringers solution) is a consideration in any cat suffering
from significant diarrhea.
Environmental Diarrhea. A variety of ingested environmental substances can cause diarrhea in
a cat. These include aspirin, acetaminophen, and other NSAIDS; coal-tar containing shampoos
and disinfectants; insecticides; and antifreeze. In such cases, the diarrhea will be accompanied
by other acute symptoms. Immediate emergency care is called for.
Nonpathogenic Diarrhea. A variety of other circumstances can involve diarrhea, which will
not, however, usually be the only symptom. These include diabetes, hyperthyroidism, kidney
disease, liver disease, exocrine pancreatic deficiency (unusual in cats except as a result of
chronic pancreatitis), and cancers of the large or small bowel. Dietary allergy or intolerance may
play a role in more complex, immune-mediated diarrhea, but sometimes is the sole cause of
bowel disorder, which is correctable by dietary means alone. Treatment in all of the
aforementioned cases focuses on the element outside the GI tract that is responsible for the GI
symptoms.
Pathogenic Diarrhea. Diarrhea can be caused by a variety of parasitic, viral, and bacterial pathogens. Although there is no record of particular enteral organisms to which FIV+ cats as a group are liable, it is reasonable to assume that immune deficits can open the way to infections. Infection can also be a complication of inflammatory disorders of nonpathogenic origins
Viruses. Among viruses are the panleukopenia (distemper) virus, a panleukopenia-like syndrome
found in FeLV+ cats, enteric coronaviruses, and astroviruses, all of which will produce
symptoms beyond diarrhea alone. Intensive supportive care is the general prescription for viral
enteritises.
Bacteria. Loss of normal intestinal bacterial flora and/or overgrowth of pathogenic resistant species as a result of antibiotic therapy directed at other problems is not uncommon. Bartonella henselae has
recently been implicated in feline gastrointestinal disease. Clostridium perfingens, part of the
normal intestinal flora in cats, can, in some strains and under some conditions of the GI tract,
produce enterotoxins that cause either acute or chronic intermittent diarrhea. Primary bacterial
causes of diarrhea in cats are usually self-limiting, and often do not require antibiotic therapy.
When they do, here is a table of some appropriate drugs and dosages [3].
Drug Dose Indications
Enrofloxacin............. 5 mg/kg q12h PO................Gram negative bacteria, C.difficile
Ampicillin................ 10-20 mg/kg q8h PO ..........Clostridium perfringens
Ampicillin.................10-20 mg/kg q8h IV, SC ...Sepsis (use with aminoglycosides)
Gentamicin............... 2.2 mg/kg q8h IV, SC........ Sepsis
Cephalothin.............. 22-44 mg/kg q8h IV, IM.... Sepsis
Metronidazole...........10-20 mg/kg q12h PO........ C. perfringens, C. difficile,
Tylosin..................... 20-40 mg/kg q12h PO C..... perfringens,
Erythromycin........... 10-15 mg/kg q8h PO...........Campylobacter
Trimethoprin-sulfa.. 15 mg/kg q12h PO, IV, SC.. Salmonella
Parasites. Many parasitic causes of diarrhea in kittens (e.g., nematodes such as round worms
and hook worms) produce little or no diarrhea in adult cats. However, FIV-induced
immunosuppression could conceivably encourage their expression. Initial infections of
toxoplasmosis are associated with diarrhea; reactivated infections associated with
immunesuppression are not. Giardiasis is a notable threat in adult cats. Giardia (a one-celled
parasite) infection, which can cause diarrhea, can induce serious weight loss. However, adult
cats infected with Giardia often have only soft stools, sometimes even normal ones.
Cryptosporidiosis is a usually self-limiting parasitic disease that can persist beyond a few weeks
in cats with underlying immune disorders.
The following are WSAVA diagnostic guidelines for persisting diarrhea of suspected pathogenic
origin:
“. . .the minimum database should include a complete blood count (CBC), a serum biochemistry
profile, a urinalysis, a fecal flotation for parasitic ova, and a direct smear of saline admixed fresh
feces for protozoa. Encysted forms of Giardia organisms in a fecal specimen may be detected
most reliably with zinc sulfate flotation, as opposed to examination of fresh saline smears.(1)
Preliminary studies in Giardia-infected cats at the University of California, Davis, have revealed
that the ProSpecT® Microplate ELISA Assay compares favorably in sensitivity and specificity to
the zinc sulfate flotation technique; however, the sensitivity of the ProSpecT® Giardia Rapid
ELISA Assay is significantly less than that of the Microplate Assay and zinc sulfate flotation
methods. Similar studies have been performed in Cryptosporidium-infected cats at the University
of California, Davis, and preliminary findings have revealed that the ProSpecT®
Cryptosporidium Microplate Assay is equally sensitive. . . .” [3]
Inflammatory Bowel Disease. IBD is, in part, a diagnosis of exclusion. A refractory bowel
inflammation for which no other cause can be found is usually labeled as suspected IBD. Like
FIV-related diarrhea, IBD is an immune-mediated inflammatory bowel disease of uncertain
etiology which is probably a group of diseases involving chronic intestinal mucosal
inflammation rather than a single disease with a single cause. In both cases, “clinical signs are
attributed to mucosal cellular infiltrates and inflammatory mediators”[4], and seem to involve
cytokine dysregulation (i.e., immune signaling and response). Attempts to characterize the
dysregulation have found no single pattern. “Pathologic interactions between intestinal bacterial
flora and the innate or acquired immune system are suspected to play a role in the pathogenesis
of IBD across species”[20].
So ideopathic IBD is a good place to go in search of clues about how to regard and treat FIV-related diarrhea for which no other cause is evident. To what extent chronic and recurrent FIV-related diarrhea should be regarded as an IBD is unclear, but a relationship is likely. IBD can
involve the small bowel, the large bowel, or both. The following table [5] offers diagnostic
criteria for locating the inflammation in dogs, but largely holds for cats, as well:

* One net vet asks his clients to bring him the diarrhetic stools in a cup. One of the things he
does is run it through a strainer looking for undigested food particles.
Because cats have a common duct exiting the liver and pancreas and emptying into the bowel,
chronic bowel inflammation can also cause concurrent inflammation of either or both. This is
called triaditis, a problem that is difficult to treat in the liver and pancreas until the bowel
inflammation has been successfully addressed.
The gold standard for diagnosing the presence and type of IBD is a biopsy of intestinal tissue,
although a thorough history, hemograms, blood chemistries, fTLI (pancreatic testing),
radiographs (including barium and radiopaque studies when chronic vomiting is present), fecal
analysis, and gut function (folate/ B12 or breath hydrogen testing for malabsorption) testing all
provide potentially useful information.
A generally accepted sequential protocol for diagnosing the cause of unexplained ongoing
diarrhea is as follows: Rule out extra-GI causes with appropriate blood testing, fecal testing, and
radiography > Rule out undiagnosed parasites with fenbendazole trial > Rule out dietary
sensitivity with a food trial > Rule out GI lymphoma with endoscopy and/or full-thickness biopsy
> Initiate antimicrobial trial with antibiotics > Initiate trial with immunosuppressive drugs [20].
3. Treatment Options
First 48 Hours
Diet:
■ Withhold food for 24 hours. Reintroduce food in small, frequent feedings..
■ Offer bland diet of boiled meat with no grains or fiber (although some vets recommend
rice.)
Motility Modulators:
■ Imodium Liquid (.2mg/ml): 1 ml/4 lbs 2 to 3 times daily
*Do not give Pepto Bismol or reformulated Kaopectate, which can be toxic to cats [6]
*Antispasmodics and anticholinergics such as aminopentamide are no longer recommended for
control of uncomplicated diarrhea.
Intestinal Coaters:
■ Slippery Elm, Plantain, or Flax Seed (for mucilage)
■ Diarsanyl
Astringents:
■ Chamomile (control intestinal water uptake)
■ Berberine-containing herbs such as oregon grape, goldenseal, coptis (inhibit intestinal
secretory response; also have natural activity against some pathogenic bacteria)
*Viable Pet has a “Support for Diarrhea” product containing agrimony, barberry root, bilberry
leaf, bistort, fennel seed, marshmallow root, plaintain leaf, psyllium seed, sage, slippery elm and
stevia leaf that may be used for up to seven days.
Longer Term
Longer-term diarrhea for which no specific cause can be found might be treated in ways
suggested by management of chronic inflammatory bowel disease.
Diet:
■ Add a fiber source to the normal diet. Options include a food specifically formulated
with high-fiber or addition of canned pumpkin (not pumpkin-pie filling) or unflavored
Metamucil (psyillium fiber).[4]
■ Change foods. Cats are obligate carnivores. Any food element not part of their natural
diet a potential source of allergy or intolerance. Options include any of the following: a
food without grains, a food without dyes and other suspect additives, or a raw diet. The
last remains somewhat controversial in FIV+ cats, but has many experienced proponents.
■ Add yogurt to the diet intermittently. ( Yogurt may, but usually does not, spark lactose
intolerance. If antibiotics are the suspected cause of diarrhea, may be started
immediately.)
■ A protein hydrolysate diet such as Hills z/d (involving protein reduction to more
absorbable form)
Supplements:
Many readily available supplements have shown clinical and/or experimental ability to favorably
impact large and/or small bowel inflammation of pathogenic or immune-mediated origin and its
effects. These include:
■ Probiotics and/or Prebiotics [7]( protection of intestinal epithelial cell and barrier
function, prevention of enterotoxin binding to intestinal epithelial cells, and regulation of
intestinal microbial environment. If antibiotics are the suspected cause, may be started
immediately.) Sacchromyces boulardii, a probiotic yeast, has specific inhibitory activity
against clostridium.
■ Digestive Enzymes (predigest food moving rapidly through the GI tract.)
■ Omega 3 & 6 Fatty Acids/Fish Oil (Inhibits synthesis of leukotrienes responsible for
allergic reactions) [8][4]
■ Lactoferrin (Immunomodulates inflammatory cytokine expression in intestines) [9]
■ Colostrum (Promotes cell wall permeability; mechanism uncertain)[10]
■ Glutamine (Improves removal of water from intestines, promotes gut permeability)[10]
*Combined with colostrum, reduced cell wall damage. Combined with probiotics, widely used to control HIV-related diarrhea.
■ Curcumin/Turmeric (Immunomodulates inflammatory response via suppression of
transcription factor NF-kB) [15]
*Has successfully controlled HIV-related diarrhea at 1862 mg daily [22]
■ Boswellia (Inhibits inflammatory leukotriene B4; outperformed sulfasalazine in treatment
of colitis) [17]
■ AHCC / Active Hexose Correlated Compound (Magnitude of antiinflammatory effect
found similar to that of sulfasalazine; higher aerobic and lactic acid bacteria counts, as
well as higher bifidobacteria counts) [18]
■ Melatonin (may have a direct effect on many GI tissues by a variety of possible mechanisms, including inhibition of nitric oxide production, COX-2 expression, and NF-κB activation; reduction of proinflammatory cytokines, bacterial translocation, and injurious macrophage activity) [21]
■ Vitamins (A multivitamin to compensate for poor GI absorption or specific vitamins such
as Vitamin E to assist in utilization of Fatty acids)
Antibiotic Anti-inflammatories.
Small intestinal bacterial overgrowth (SIBO) is a major secondary complication of many bowel
diseases [16]. It has been noted that bacteria characteristically inhabiting the large intestine are
found in unusual numbers in the small intestine. Clostridium and e coli have been singled out in
a number of studies. Natural antibiotics with activity against these bacteria may be of value.
■ Metronidazole
■ Tylosin
Pharmaceutical antibiotics such as metronidazole have anti-inflammatory immunomodulating activity in addition to antibiotic activity, are useful for controlling bacterial overgrowth, and have been shown to be safe for
sustained use over extended periods; some inhibition of T-cell recruitment, but acceptable for FIV+ cats. One source has noted instances when fluoroquinolones (enrofloxacin, marbofloxacin, etc.)
produced dramatic results after metronidazole and immunosuppressive drugs (see below) had
failed to have an impact [20].
Inflammatory Bowel Disease
This file is not about Inflammatory Bowel Disease as such, only about IBD as a model for
approaching FIV-associated diarrhea. Treatment of IBD (or use of an IBD-inspired treatment
strategy) should be coordinated with a veterinary practitioner of some sort.
Dietary:
■ Elimination Diet–Feeding a novel protein only ( ie., a meat source that the cat is
unfamiliar with, such as lamb or rabbit) to establish allergy to or intolerance of a usual
dietary component [4].
Other Natural Therapies (See Longer Term>Supplements):
■ Teas, Tinctures, Herbs–2 parts slippery elm or plantain, 1 part marshmallow root, 1 part
licorice root, 1 part fennel seed [11]
■ Supplements–250mg n-acetylglucosamine, 250mg glutamine, 10mg proanthocyanidin
complex, 50mg DMG, 250mg vitamin C [12]
Antacids
■ Xantac (ranitidine), more often used for vomiting or megacolon, is sometimes of help
with IBD diarrhea, as well.[13]
Steroidal Anti-Inflammatories::
■ Prednisolone, Prednisone (1-2mg/kg) [4] (Use with caution in FIV+ cats)
■ Budesonide [14] (Has a localized action that makes it worth trying before systemic steroids such as prednisolone or prednisone)
Other Antibiotic Anti-Inflammatories: (See Longer Term> Antibiotic antiinflammatories)
■ Sulfasalazine (10-12 mg/kg every 12 hrs), Azathioprine
■ Mesalamine, Olsalazine (5ASA human drugs now being used with caution on cats)
Immunosuppressive drugs: (Stongly inhibit T cell recruitment and amplification; not a realistic alternative for FIV+ cats)
■ Cyclosporin
■ Chlorambucil
