Abstract
ABSTRACT: The prevalence of chronic gastritis in dogs that was associated with drug induced, dietary cause/food allergy, bacterial, systemic causes, foreign body and due to anatomical defect was recorded as 14.92, 14.92, 16.42, 17.91, 12.69, 12.69 and 10.45 per cent, respectively. Prevalence of chronic gastritis of various causes mentioned above, in relation to breed, was recorded highest among German shepherds and Labradors respectively, and lowest in Daschunds, Cocker spaniels, Spitz, Golden retrievers, Mongrels and Dobermans respectively. With respect to age, highest prevalence was recorded in dogs aged between 1-7 years (drug induced, bacterial, foreign body and anatomical anomalies), following upto 1yr (parasitic, food allergy, foreign body and anatomical defect) compared to the chronic gastritis in dogs under 12 months (drug induced and systemic causes). The prevalence of chronic gastritis in relation to gender of affected dogs revealed a highest rate in males in contrast to females. Except in bacterial gastritis, temperature, pulse and respiratory rate of vomiting dogs of various etiology remained in normal range. Dehydration, vomiting with mucous, fresh blood, partially digested blood, blood clots, coffee colored, bile, undigested food were the significant clinical manifestations. Whereas, icterus and pruritus was recorded in systemic disease and dietary indiscretion associated chronic gastritis in dogs. Significantly decreased TEC, Hb, with elevated PCV and TLC was common hematological abnormalities among all the chronic gastritis affected dogs. Except neutrophilia and monocytosis among bacterial gastritis in dogs, no difference was noticed with other dogs. Similarly, elevated levels of ALT and ALP with decreased TP and albumin were recorded among the vomiting dogs of both the subgroups of groups II, III and IV. Further, hyponatremia, hypokalemia and hypochloremia were the common electrolyte abnormalities in all the gastritis affected dogs. Megaesophagus, lower esophageal stricture / stenosis, foreign body obstruction and esophageal diverticulum were the significant radiographic abnormalities. A thickened gastric wall, thickened rugal folds, and loss or decreased definition of the normal gastric wall layers were identified ultrasonographically in dogs with chronic gastritis. Reddening, roughening, petechiation, haemorrhage, perforations, increased granularity or friability, constrictions, erosions, ulcers and mass lesions and rugal and mucosal thickening or hypertrophy along the mucus lining of cardiac, fundus and pylorus were significant endoscopic abnormalities. Culture studies of biopsy samples from stomach revealed negative result but the same sample on rapid urease test revealed positive results for Helicobacter spp. Histopathologically, eosinophilic, lymphoplasmacytic (lymphocyte and plasma cell dominated), ulceration, granulomatous (macrophage dominated), pyogranulomatous (neutrophils and macrophages), fibrosis were specific findings. Following therapy for 5 days with respective regimens, the specific signs, hematological, biochemical and other findings improved significantly among both the subgroup dogs of the group I(drug induged gastritis), II( dietary induced gastritis), III (helicobacter associated) and IV (gastritis due to other systemic causes) dogs that were treated for varied etiology. However, relatively faster clinical recovery and early improvement with respect to various hemato-biochemical parameters were observed among the sub group ‘b’ dogs of I, II, III and IV group dogs. However, with respect to various endoscopic abnormalities like ulcerations, erosions, hypertrophic, thick gastric mucosa that were noticed in chronic gastritis affected dogs before the onset of therapy did not showed complete recovery (except clinical improvement) by the end of day 5 except healing and absence of ulcers and erosions (fig. 69 to 70). Whereas, Helicobactor associated gastritis in dogs that were found positive for rapid urease test also showed clinical improvement by absence of vomiting and normal appetite by day 5. However, complete recovery without presence of the specific bacteria was only noticed after two weeks.
