Patents by Inventor David Maxwell Lyerly

David Maxwell Lyerly has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7892762
    Abstract: A method for aiding in differentiating irritable bowel syndrome from inflammatory bowel disease by determining the level of total endogenous human lactoferrin in clinical specimens, such as feces, mucus and bile, wherein an elevated level of lactoferrin substantially precludes diagnoses of IBS and other noninflammatory etiologies, and a kit usable in such method are provided. Further provided is a method for quantitating the level of total endogenous human lactoferrin in clinical specimens, such as feces, mucus and bile, to monitor gastrointestinal inflammation in persons having inflammatory bowel disease.
    Type: Grant

  • Patent number: 7785818
    Abstract: A method for the differentiation of inflammatory bowel disease (IBD) from irritable bowel disease (IBS) followed by distinguishing ulcerative colitis and Crohn's disease from other gastrointestinal illnesses. This highly differential method first uses the presence of elevated lactoferrin as a marker of intestinal inflammation to differentiate IBD from IBS. Patients suspected of IBD are then analyzed for fecal anti-Saccharomyces cerevisiae antibodies (ASCA) as an indicator of Crohn's disease and fecal anti-neutrophil cytoplasmic antibodies (ANCA) as an indicator of ulcerative colitis. IBD patients are further monitored for intestinal inflammation using fecal lactoferrin to evaluate the effectiveness of medical therapy and to predict relapse. The apparatus comprises either a qualitative enzyme-linked immunoassay or other immunoassay that utilizes antibodies specific to human immunoglobins for the measurement of total endogenous lactoferrin, ASCA and ANCA in human feces.

  • Patent number: 7736858
    Abstract: A method and apparatus for the differentiation of ulcerative colitis from Crohn's disease and other gastrointestinal illnesses using the presence of anti-neutrophil cytoplasmic antibodies (ANCA) as a marker of ulcerative colitis is described. The apparatus consists of either a qualitative enzyme-linked immunoassay or other immunoassay that utilizes antibodies specific to human immunoglobulins for the measurement of total endogenous ANCA in a human sample. The method and apparatus can be used by healthcare providers to distinguish ulcerative colitis from Crohn's disease and other gastrointestinal illnesses.

  • Patent number: 6872540
    Abstract: A method and apparatus for the differentiation of Crohn's disease from other gastrointestinal illnesses, such as ulcerative colitis and irritable bowel syndrome, using the presence of fecal anti-Saccharomyces cerevisiae antibodies (ASCA) as a marker for Crohn's disease are provided. The apparatus includes an enzyme-linked immunoassay or other immunoassay that utilizes antibodies specific to human immunoglobins for the measurement of total endogenous ASCA in a human fecal sample. The method and apparatus may be used by healthcare providers to distinguish Crohn's disease from other gastrointestinal illnesses, such as ulcerative colitis and irritable bowel syndrome.
