2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98.
Autoimmune diseases are related to the disruption of host immune systems. Chronic autoimmune diseases, such as autoimmune hemolytic anemia (henceforth AIHA), immune-mediated hemolytic anemia (henceforth IMHA), inflammatory bowl disease (henceforth IBD), and atopic dermatitis (henceforth AD), typically require consistent treatment with anti-inflammatory drugs such as corticosteroids and immune suppressors such as cyclosporine and azathioprine.
Long term application of these drugs can cause significant drug side effects. As soon as the symptoms are under control, medical doctors and veterinarians often try to reduce dosages or to eliminate entirely the use of these drugs. Unfortunately, the remission of disease makes this approach very challenging. This has created a demand for therapeutics comprised of natural materials with few or no side effects to treat these chronic autoimmune diseases or to reduce the side effects of anti-inflammatory drugs and immune suppressors.
AIHA in humans and IMHA in canines and felines, is an immune disorder caused by antibiodies directed against unmodified autologous red cells. AIHA is an increasingly recognized complication of anti-neoplastic therapy in cancer patients, in particular those with chronic lymphocytic leukemia (henceforth CLL). In addition, AIHA is quite often seen in patients with infectious diseases, sometimes in “collagen disorders’ which are systemic autoimmune disorders, and sometimes after organ transplantation. These disorders are acute or chronic diseases.
Inflammatory bowel disease (henceforth IBD) is a general term to describe chronic intestinal inflammation, in which inflammatory cells have spread to the gastrointestinal (henceforth GI) tract. Depending on location and nature of the inflammatory changes, IBD can be classified into two major types—Crohn's disease and ulcerative colitis. Crohn's disease can affect any part of the GI tract with a majority of the cases starting in the ileum. Ulcerative colitis is restricted to the colon and rectum. IBD is considered to be the most probable cause of chronic vomiting and diarrhea in cats (Omi et al., 2008). It is well established that intestinal microflora play an important role in the pathogenesis of IBD (Heilpern and Szilagyi, 2008; Kanauchi et al., 2009). The intestinal microflora is a large bacterial community that colonizes the gut and which affects the physiology and pathology of the host's mucosal immune system (Mamaskos and Kolios, 2008).
The skin is the largest immunologic organ by area and is affected by both external and internal factors, as well as innate and adaptive immune responses. Many skin disorders, such as atopic dermatitis (henceforth AD) are immune mediated. Most of dermatologic diseases are chronic, inflammatory, and proliferative (Fonaciet et al., 2010). Steroids are often used as the first-line treatment of AD, and have been shown to be very effective in improving the symptoms; however, steroids can also cause severe side effects. Other medications such as cyclosporine have been shown to be effective in treating severe AD, and may be used as a substitute for steroids. However, the complications of side effects associated with long-term application can be serious (Haw et al., 2010).
Animals and humans suffering from AD, IBD, AIHA, and IMHA have disruptions of their immune systems and often require long-term steroid and/or immuno-suppressor treatment. A great deal of emphasis has been placed on reducing and alleviating the many severe side effects that these powerful treatments can cause.
The standard treatment in dogs and cats with chronic digestive disorders such as IBD or nonspecific enteropathies (henceforth NPE) is feeding a nutritionally balanced, highly digestible elimination diet. Alternatively, long term administration of multiple drugs, including digestive drugs, antibiotics, immune suppressors, and inflammation suppressors to cats and dogs have been adapted. However, long term, multi-drug regimens cause severe side effects to dogs, cats and humans (Jergens, 1999, Allenspach et al., 2006). It is desirable to reduce the number of drugs used in treatment as soon as symptoms are reduced and the patient is stable. Similar multiple drugs are used in treatment of dogs suffering from chronic diseases such as IMHA (Grundy and Barton, 2001) and such skin diseases as AD. Unfortunately, the recurrence of symptoms is often observed when the amounts of drugs are reduced, especially in the case of reducing corticosteroids such a prednisolone.
Probiotics are beneficial microorganisms that naturally exist in the GI tracts of humans and animals. Oral administration of adequate amounts of probiotics reestablishes the micro-ecosystsms in GI tracts and have been shown to alleviate antibiotic-induced diarrhea (Kaur et al., 2009). Among different probiotics, Pediococcus adidilactici is reported to have better resistance against high temperatures, oxygen exposure, and stomach acid environments than other probiotics (Lin, 2006, Lin and Ishida, 2008). Enhanced immune responses in broiler chicken and rats were noted when the animals were given P. acidilactici alone or in a combination of P. acidilactici and Saccharomyces boulardii (Lee et al., 2007). S. boulardii was also described to enhance immune responses against Clostridium difficle toxin A (Qamar et al., 2001). Rats fed with P. acidilactici and S. boulardii had both B-cells and T-cells significantly increased (Lin and Ishida, 2009). When high amounts of live P. acidilactici were administered with antibiotics, substantial numbers of live P. acidilactici were able to survive even under antibiotic treatment. Therefore, administering P. acidilactici and S. boulardii together with antibiotics or other drugs can be a routine treatment for dogs and cats suffering from digestive disorders (Mitztani et al., 2007, Lin and Ishida, 2008).

The method comprises the steps, obtaining a probiotic preparation of living microorganisms, and administering an effective amount of the probiotic preparation to the mammal, including a human and a pet requiring treatment for autoimmune anemia who is being treated with steroids and immune suppressors.
Embodiments include a method of reducing side effects associated with steroid and immune suppressor treatment and reducing the dosage of steroids and immune suppressors required to treat inflammatory bowl disease or nonspecific enteropathies disease or atopic dermatitis in mammals, including humans and pets requiring such treatment. The method comprises the steps, obtaining a probiotic preparation of living Pediococcus acidilactici and Saccharomyces boulardii, and administering an effective amount of the probiotic preparation to the mammal, including a human and a pet with inflammatory bowl disease or nonspecific immunopathies disease or atopic dermatitis which is being treated with steroids and immune suppressors.
In this disclosure, IBD means inflammatory bowl disease; NEP means nonspecific enteropathies disease; IMHA means immune-mediated hemolitic anemia, AIHA means autoimmune hemolytic anemia; GI means gastrointestinal; MMS means probiotics comprised of P. acidilactici and S. boulardii microorganisms; PCV means pack cell volume; EOD means every other day; AD means atopic dermatitis. IMHA TREATMENT.
AIHA in humans, and IMHA in canines and felines, is an immune disorder caused by antibiodies directed against unmodified autologous red cells. The disorders are acute or chronic diseases.
The conventional therapy of warm antibody AIHA or IMHA is treatment with glucocorticosteroids with or without high doses of immunoglobins. After initial remission, the dose is tapered down slowly and with caution, and in some cases, low-dose maintenance therapy is required (Valent and Lechner, 2008). If the response to glucocorticosteroids is not adequate, the immune suppressor, cyclosporine A, is a reasonable choice for the treatment (Diehl and Fetchum, 1998). The side effects of long term drug applications remain a main concern.
Embodiments of the current disclosure involve administration of P. acidilactici and S. boulardii probiotics together with steroids and/or immune suppressors to cats and dogs suffering from the chronic diseases IMHA and IBD. Inclusion of probiotics along with steroids and/or immune suppressors was found to allow the use of reduced amounts of steroids and/or immune suppressors.

4Packed Cell Volume (PCV) is the standard protocol to measure the amount of blood cells of animals.
Table 3 shows the effect of treatment with probiotics comprised of P. acidilactici and S. boulardii on the amount of steroid Prednisolone and immune suppressors cyclosporine or azathioprine required to treat dogs afflicted with IMHA. In all cases the level of steroid and immune suppressor required was reduced. In three cases the immune suppressor was eliminated. In all cases the health of the animals improved, as indicated by substantial increases in packed cell volume, with low packed cell volume an indicator of IMHA.
Diagnosis of animals with IBD or NEP. IBD diagnosis requires ruling out all other possible causes for chronic intestinal inflammation, as well as confirmation by the presence of excess inflammatory cells in the GI tract (Omi et al., 2008). Several diagnostic tests were run: 1) history of suffering from chronic digestive disorders such as vomiting, diarrhea, loss of appetite, or weight loss over an extended period of time, 2) fecal sample analysis, blood analysis, and the application of antibiotic treatment to eliminate pathogen or parasite infections, 3) either biopsy or endoscope for pathological analysis of the inflammatory cells on the surface of the GI tracts. For patients diagnosed as IBD all three above diagnostic procedures were used. For patients diagnosed as NEP, only the first two diagnostic procedures were used, or the history of digestive disorders was less than three weeks.
Table 2 summarizes the results of further administrating probiotics P. acidilactici and S. boulardii along with prednisolone and immune suppressors to cats and dogs with chronic diseases.
Line 1 summarizes the treatment of two cats and four dogs with IBD with prednisolone and immune suppressors as well as probiotics P. acidilactici and S. boulardii performed in six animal hospitals in Japan and the USA according to the protocols in
Line 2 summarizes the effects of treatment of animals with nonspecific enteropathies (henceforth NEP) with prednisolone and/or immune suppressors. When cats and dogs suffer from chronic digestive disorders the possibilities of bacterial or parasite infection were excluded by extensive examination of fecal analysis, blood tests, and antibiotics treatments. However, pathological confirmations by biopsy analysis were not performed and these cats and dogs were described to have NEP. In six animals diagnosed as NEP, two cases were treated with a once daily P. acidilactici and S. boulardii probiotics capsule after antibiotics treatment was completed, and the digestive disorders were controlled successfully. In four cases a once daily P. acidilactici and S. boulardii capsule was administrated along with prednisolone and/or immune suppressors. Of these four cases, three cases clearly showed the reduction of prednisolone dosages, and in one case it was possible to eliminate prednisolone treatment.
Line 3 summarizes the treatment of seven dogs with IMHA with probiotics P. acidilactici and S. boulardii and with prednisolone and immune suppressors following the protocol of
Line 4 is the summary of all 19 chronic cases which included animals with IBD, NEP, and IMHA. The administration of P. acidilactici and S. boulardii probiotics together with steroids and/or immune suppressors made possible the reduction of steroid and immune suppressors dosages in long term applications. In four cases it was possible to eliminate steroids and/or immune suppressors without any relapses.
In summary, the addition of probiotics P. acidilactici and S. boulardii into the conventional IBD treatment allowed for complete termination of antibiotic treatment in two IBD dogs and one NEP cat and in two NEP dogs. Conventional antibiotic treatment in one NEP cat was successfully terminated.
Addition of probiotics P. acidilactici and S. boulardii allowed successful reduction of prednisolone dosage in two IBD cats and one IBD dog and one NEP dog. Prednisolone and antibiotic administration was completely terminated in one NEP dog with probiotics P. acidilactici and S. boulardii.
Bloody diarrhea in one NEP cat was successfully treated with probiotics P. acidilactici and S. boulardii and diet changes for six months without use of any prescription drugs.
These results showed that administering probiotics P. acidilactici and S. boulardii to IBD or NEP dogs or cats was without negative effects and helped to reduce or to terminate conventional drug treatment, such as Prednisolone or antibiotics.
MitoMaxSuper means a probiotic capsule containing 400 mg of one billion live dried mixtures of P. acidilactici and S. boulardii.
The results shown in Table 3 show that a cat and dog with NPE, and a dog with IBD had symptoms relieved by treatment with a capsule of a probiotic comprising of P. acidilactici and S. boulardii.
Table 4 shows the effect of treatment of dogs with atopic dermatitis with probiotics Pediococcus. acidilactici and Saccharomyces boulardii. The results indicated most dogs were helped by such treatment with 60.8% showing significant improvement; 13.1% showing good improvement; and 26.1% showing no improvement.
