Boot's Story: |
![]() |
Lymphocytic plasmacytic stomatitis (LPS) is thought to be an auto immune disease of the gums and lining of the mouth and throat, although the exact cause is unknown. It can only be confirmed through biopsy. Although the symptoms may appear the same, do not mistake this disease with chronic gingivitis which is almost always due to tartar buildup. CAUTION: It is IMPORTANT to understand that an auto-immune response is typically caused by an abnormal, HYPERACTIVE, overstimulated immune response. Please do NOT give your cat immune stimulants or supplements without checking with your veterinarian. Stimulating an overactive immune system might make matters worse.
The first thing to understand about this condition is that this disease can be a secondary symptom of a greater underlying viral infection such as Feline Immunodeficiency Virus, Feline Leukemia, Feline Herpes (aka Rhinotracheitis) or Calicivirus, or it may be an immune response gone awry. Current theories are that the cat develops an allergy to tartar. Always, always have your kitty tested for FeLV and FIV if faced with this condition. Fortunately Boots tested negative, both at the shelter, and by our own veterinarian, however our vet did conclude that Boots was chronically infected with Feline Herpes.
These viruses may cause other symptoms besides the stomatitis. You may notice your cat is more susceptible to upper respiratory infections and eye problems. As this condition is also thought to be associated with auto immune deficiency, you are also dealing with a disease that is triggered by stress. The stress of being in a shelter for two years had eroded Boots' mouth and gums to the point where he couldn't swallow. He weighed seven pounds when we brought him home in August of 1996.
The two biggests things we have found to make a difference in the management of this disease are Interferon, an anti-viral medication developed for use in humans, and Lysine which is used to treat human Herpes viruses. We now have nine years experience with Interferon and 4 with lysine, and we have seen a dramatic dramatic improvement with Boots.
Boots' stomatitis was very severe with involvement down the throat and into the larynx and the loss of 3 teeth, but we have
managed to stabilize it to the point where he's now eating boiled
chicken
(spoiled cat) and supplemented with Felovite II which gives him the essnetial Taurine and other good stuff the chicken doesn't contain (thank you Tomlyn!). He has almost doubled his weight since we began this
protocol.
Our initial routine with him was teeth and gum cleaning and
cortisone if necessary every 3 months, Antirobe (Clindamycin) antibiotic 1 cc X2 daily, and 1 cc
of diluted (30 units per 1 cc of sterile water) Interferon a day. Cortisone (Depo-Medrol) is also common therapy for this disease. But you
want to try to minimize the amount you have to give as
it has long term side effects. Used judiciously it helps to control the
inflammation and pain. Some cats require cortisone on a monthly basis,
however we have found that the Interferon has significantly reduced the
progress of the disease, therefore we are giving it less often. Our doctor
mixes the Interferon in the correct diluted dosage and freezes it in 10 cc
syringes. Interferon has a very short shelf life and cannot be kept in the refridgerator over an extended period of time. We
thaw one syringe and use it for 10 days. It is given orally, and is
mostly
water, so there's no taste. You can either syringe it directly into the
mouth or mix it into food. We began supplementing the Interferon treatments with lysine after Sammy, our other Herpes cat, developed a Herpes eye infection. On the advice of the veterinary opthamologist we began Sammy on 250 mgms of lysine twice a day and extended the treatment to Boots as it helped Sammy so much. Lysine interferes with the Herpes virus's ability to multiply. It's similar to Interferon in that it is an anti-viral, BUT it is SPECIFIC to the Herpes virus only. If you have ruled out stomatitis being caused by FIV or FeLV viruses and you suspect the underlying cause might be Herpes you should definitely add Lysine to the Inteferon treatment.
Regular teeth cleaning is necessary to control tartar buildup which can make
the mouth and gum ulcers worse and also open the body up to serious
infection, so its important that you monitor this closely.
Interferon is a drug that was originally developed for human cancer intervention, and is also being used in human AIDS & Hepatitis treatments. Veterinarians are having success treating cats using extremely low dosages on a daily basis to eliminate the peaks and valley effect (see related page on Interferon). Consequently it is being used to treat or manage many feline viral infections including calcivirus, herpes (both of which have stomatitis as a complication), Feline Leukemia, Feline Immunodeficiency Virus and even Feline Infectious Peritonitis.
If all else fails, removal of all the back teeth seems to provide relief. While this might seem extreme, cats can do very, very well without teeth and the quality of their lives can be excellant.
I was reluctant to take home a sick cat, so soon after having lost my beautiful Tardy. But Boots caught my eye, and I know without a doubt it was Tardy who had pointed him in my direction. Boots was so pathetic looking, scrawny and haggard. I knew the wonderful volunteers at the shelter were doing everything they could to help him, but I also knew Boots was slowly failing, and that he would be hard to place. I couldn't leave him there, even though I thought at the time I was opening my heart to eventual grief. The shelter had been very, very careful to be sure I understood this was a lifetime problem. I took him on a foster basis, not yet ready to deal with what I thought was a terminal illness which would lead me to more grief. But after the first few hours of having him in a real home and watching him bound delightedly from empty room to empty room, I knew Boots was home, and I called to say he wasn't leaving. The shelter waved the adoption fee. Not knowing anything about stomatitis, I had no idea how much could be done to manage this disease. Two years later Boots now weighs over 14 lbs. He purrs now, and he plays with the other cats. He rules the house. I know that God and my rainbow Tardy are watching over us, but I also know the real difference in these animal's lives has been the experience and the unbelievable knowledge of our vet. It has been the deciding factor in our ability to maintain their health.
If, for any reason you feel that your vet isn't dealing with this properly, I urge you to seek a second opinion. The key to our success lay in the fact that our doctor keeps up with current trends, and with the published literature, and we are the beneficiaries of his dedication to his profession. I leave you with one final thought. Don't lose hope! Boots has taught me that although you might face the pain of losing an animal, it is always worth the risk to open up your heart, to love and to try. The reward is indescribable. I often wake up in the middle of the night to find Boots nuzzled against my face, purring.
Below you will find a number of links I have collected regarding Stomatitis, Viral diseases for which stomatitis is an opportunitistic symptom, and some info on Interferon & lysine.
![]() ![]() ![]() Boots today, at 15 lbs, healthy and happy.
Postscript: I have always believed that Tardy led us to Boots. On June 4, 1997 I finally trapped and took in a stray that had been visiting us for several weeks. The first thing our doctor did was look at his mouth. We now have two cats with this disease, and two cats who are thriving because of our vet's skill and Interferon. Sammy lives indoors with us now, and Tardy watches over us still. December, 2003 Update: 7 1/2 years on daily Interferon and Boots continues to thrive and be happy. February, 2005 Update: Boots developed a malignant Plasma Cell tumor on his left hock. After consultation with a veterinary oncologist we decided on a series of 15 radiation treatments which I journalled on a separate page. Boots' Story Part II: Cancer January, 2006 Update: Boots' cancer is still in remission a full year after the radiation treatments. 9 1/2 years Boots has been on daily Interferon-Alpha. Both his and Sammy's stomatitis remain in remission and we continue with 30 units of Interferon-Alpha and 500 mgms Lysine daily. Boots' chronic renal failure has been managed for the past 5 years. We are blessed. March 10, 2006 Update: We lost Boots today. We set him free from the cancer that was discovered in January. A different cancer from his previous one. An aggressive cancer that caused him to lose weight. He lost almost a pound last week. His job here was done. He came to give us love, and for us to give love back, and that task was completed a thousand fold over. My last gift to him was to set him free. Soar high my sweet boy. You live in my heart forever. And we will meet again. |

Topical and oral use of alpha interferon has been advocated in the treatment of persistent or severe Herpes felis keratoconjunctivitis in cats, but may be most effective when used early in acute infections"
Viral Conjunctivitis - Dr. Susan Carastro, DVM: "topical antiviral drugs (i.e., Viroptic or idoxuridine)...Oral L-lysine, a nutritional amino acid supplement, has been shown to limit the severity of the infection and recurrent bouts of infection.

What is Interferon, And How Does It Work?
Interferon is a medication developed to treat human viruses like Cancer, AIDS and Hepatitis C. It's primary effects are anti-viral, anti-proliferative and immunomodulatory. Low dose Interferon-a therapy serves to mimic the natural interferon activity in the cat's body in response to a viral invasion. It either supplements or replaces the cat's own interferon production. We have moved our Interferon information to a separate page. Some of it is quite technical and relates to it's action in human viral infection, but if you read between the lines you'll get the gist of the significance Interferon plays in fighting feline viruses.
WHAT IS INTERFERON AND HOW DOES IT WORK?
What is L-lysine and how does it work?
L-lysine is an amino acid that can be found at any health foods or nutrition store. We buy the 500 mgm capsules, Solaray brand. I pull the capsule apart and place 1/2 the powder contents in a small dish for Sammy. I mix it with a tablespoon of canned cat food gravy and I get him to slurp it up before giving the rest of the meal. I put the capsule back together and save the remaining half of the powder for the evening dose. I repeat the same process in the evening only I add the 1 cc of Interferon to the mix.
Boots is more finicky. For him I have to empty the powder into a 1 tablespoon coffee ground measuring cup. I then syringe about 3/4 of a cc of either water or canned food gravy into the measuring cup, smoosh it all together until dissolved and syringe it back up and squirt it into his mouth.

L-lysine dosages - From Dr. Mike Richards, DVM
L-lysine Archives - From Holisticat
Feline Herpes Virus - Purina One: "L-lysine, which is an amino acid, has been found to interfere with the replication of FHV-1."
Whats New in the Treatment of Herpes - "Tissue culture studies have demonstrated a beneficial effect on viral replication when the amino acid ratio of arginine to lysine favors arginine. The opposite, preponderance of lysine to arginine, suppresses viral replication and inhibits cytopathogenicity of herpes simplex virus"
L-Lysine: Herpes ammo - Lysine inhibits arginine which helps Herpes to replicate. Keep in mind dosages mentioned in this article are for HUMANS. Dosage for cats is 250 mgms twice a day.

Interferon Use for Feline Viruses - A Cat Clinic, Edinbourogh, Scotland
Interferon Therapy - Island Pharmacy. Interferon Alpha can be ordered from this on-line pharmacy with a prescription from your vet.
A Note on Feline Interferon Omega: Feline Interferon Omega is currently being tested in Europe. It is not available as yet in the United States, however it is being investigated by the FDA. Feline IFN-O promises to be more effective and easier to use in treating feline viral diseases, but until FDA approval Interferon-Alpha daily dosing remains our best option.
Survival of Symptomatic FeLV and FIV positive Cats Treated with Feline Omega Interferon - World Small Animal Congress, 2001 - "the survival probability over a 6-month period of FeLV or FeLV and FIV symptomatic cats was 2.2 times higher in the treated cats."

Dr. Mike Richards, DVM on FeLV - "There are vets that use interferon continuously. I have seen this recommendation on the Veterinary Information Network from Dr. Alice Wolf, who is associated with the veterinary college at Texas A&M. Dr Wolf is one of the leading authorities on infectious diseases in cats"...."Interferon is an immune system modulator that some vets believe is helpful
in prolong the quality and/or quantity of life in cats infected with feline
leukemia virus. I do not have an opinion either way on this but it seems to
be pretty safe. "... "Some vets feel that using
interferon is helpful in improving the overall quality of life for cats infected with feline leukemia. It is worth trying
since it seems to be very safe. ..."It
does appear to be very safe and I see no reason not to try it. "
FeLV from Cornell - "Various antiviral compounds including interferon may also be used
to treat cats with FeLV infection. Those compounds, while still
experimental, are generally safer to use than chemotherapeutic
agents, and may reduce the amount of virus present in the blood of
the cat, and may extend the period of remission of clinical disease."

Feline Immunodeficiency Virus (FIV):

FIV & FeLV Companion Animal Medicine Notes - From the College of Veterinary Medicine, Missouri:
"4. Interferon – (human recombinant interferon-alpha Roferon or Intron A) The recombinant human form seems more beneficial than the bovine or feline products. The natural human Interferon alpha (Cantell) requires less units for low dose treatments (0.5 units per day of natural vs. 30 units per day for recombinant)
At high doses Interferon alpha has direct antiviral activity and at low doses it has immune stimulating effects –(at high doses it also suppresses overzealous eosinophil production)
At low doses Interferon alpha is reported to enhance T-cell, macrophage and natural killer cell function and induce release of other “beneficial” cytokines.
1,000-10,000 U/Kg IM SID – enhances lymphocyte responses and decreases viral load; cats may develop neutralizing antibodies to interferon at 3 to 7 weeks of use at this high dose. Adding AZT didn’t improve treatment.
30 units PO SID long term or one week on and one week off, etc. – safe, does
not stimulate antibody production, inexpensive, convenient – antecdotally helpful
to reduce clinical signs and improve “well-being” of these infected cats. Roferon
or Intron A comes in 3 million unit vials so it has to be diluted tremendously and
kept refrigerated – stays good for several months once diluted. How oral
interferon alpha works is not known but it doesn’t get into blood stream or oral
cavity in high enough doses to be directly antiviral. It is speculated that
Interferon alpha binds to mucosal receptors, triggering an immunological
cascade with advantageous systemic effects."
What You Should Know About FIV - "Alpha interferon. This drug may reduce viral replication in some infected cats. It is not licensed for use in cats, but some clinical studies found increased activity, increased appetite, improvement of blood abnormalities, increased clearance of virus and prolonged survival in treated cats."
