ThesisItem Open Access CLINICO - DIAGNOSTIC STUDIES ON ASCITES IN DOGS(SRI VENKATESWARA VETERINARY UNIVERSITY TIRUPATI - 517 502. (A.P.) INDIA, 2023-03) DHILEEP KASTHURI; LAKSHMI RANI .N (MAJOR); SURESH .K; SREENU MAKKENAThe present investigation was carried out at VCC, NTR College of veterinary science, Gannavaram and SSVH, Vijayawada from June to December 2022. The overall occurrence of ascites was 1.02 per cent (48/4704). The common causes of ascites included hepatic origin (43.75%), cardiac origin (20.83%), renal origin (12.50%), mixed origin (14.59%), parasitic origin (4.17%) as well as hypoproteinemia and neoplastic origin (2.08 per cent) each. Higher occurrence was seen in dogs aged above seven years (37.50%), male dogs (58.33 %) and Labrador Retriever (39.58%) breed. Higher occurrence of hepatogenic ascites was recorded in dogs aged between 1-4 years (33.33%) while cardiogenic ascites (50.00%) in dogs aged in between 4 to 7 years and nephrogenic ascites in dogs of above 7 years (50.00%). The common clinical signs observed were abdominal distension with fluid thrill on percussion (95.83%), inappetence (47.91%), pale mucous membrane (54.17%), vomiting (41.66%), exercise intolerance (39.58 %), respiratory distress (37.50%), dark yellowish urination (35.41%), melena (33.33%), anorexia (31.25%) ,cough (25.00%) and majority of dogs exhibited grade 2 ascites ( 58.33%).Significantly higher (P<0.01) mean values of pulse and respiratory rate was recorded in cardiogenic ascitic dogs in comparison to other etiologies studied. Haematology revealed significantly (P<0.05) decreased Hb and PCV values in all the ascitic groups, significant (P<0.05) reduction in TEC values in ascitic dogs with hepatic and renal origin whereas ascitic dogs with hepatic origin showed significantly(P<0.05) increased TLC value. Neutrophilic, lymphocytopenia was observed in all ascitic dogs. The biochemical changes observed were hypoproteinemia and hypoalbuminemia in all the ascitic dogs. Significantly(P<0.05) elevated ALT activity was observed in ascitic dogs with hepatic and mixed origin, increased AST activity in mixed origin, and ascitic dogs with hepatogenic, cardiogenic and mixed origin showed significantly(P<0.05) increased ALP activity where as hypoglycemia was noticed in ascitic dogs with hepatic and mixed origin. Elevated serum creatinine, BUN and phosphorous levels were observed in ascitic dogs with renal and mixed origin. Hyponatraemia and hypokalaemia were observed in all the ascitic dogs. The ascitic fluid analysis revealed significant (P<0.05) decrease in total protein and albumin concentration (g/dL) and significantly higher mean SAAG value (g/dL) in ascitic dogs with hepatic origin (2.15±0.17) than other study groups. Majority of the fluids recovered on abdominocentesis were transudates (50.00%). Low voltage QRS complex was observed as the major ECG abnormality (25.00%), followed by arrhythmias (12.50%). Radiographically, ground glass appearance of abdomen was observed in majority of dogs (91.42%) and cardiomegaly (34.28%) and pericardial effusion in 11.42 per cent of ascitic dogs. Abdominal ultrasonography revealed presence of anechoic peritoneal fluid in all the dogs (100.00%). Echocardiography revealed pericardial effusion in four dogs (10.00%), mitral regurgitation in 8 dogs (20.00 %) and tricuspid regurgitation in 7 dogs (17.50%). Out of 48 dogs diagnosed with ascites, 16 dogs (33.33%) died. The serum biochemical parameters revealed significant difference (P<0.05) in ALT and serum phosphorus values between survivors and non survivors.ThesisItem Open Access EVALUATION OF RENAL FUNCTION IN DOGS AFFECTED WITH PYOMETRA(SRI VENKATESWARA VETERINARY UNIVERSITY TIRUPATI - 517 502. (A.P.) INDIA, 2023-04) ANURADHA RAVINDRA GANGAVATI; LAKSHMI RANI .N (MAJOR); SURESH .K; SRINIVAS .MThe present study was undertaken to study the renal dysfunction in dogs affected with pyometra. The occurrence of pyometra was observed to be 2.02 per cent among a total of 1383 female dogs presented during the study period. The pyometra dogs were subjected to detailed clinical and haemato-biochemical examination to assess renal function in dogs. In the present study, based on elevated levels of serum creatinine and BUN values, the pyometra dogs were categorized as azotemic (Group I) and non azotemic (Group II). The occurrence of azotemia (Group I) in dogs accounted up to 42.86 per cent whereas 57.14 per cent were non-azotemic (Group II). The occurrence of pyometra with or without azotemia was more in Pomeranian breed with majority of the dogs in the age group of 5-10 years. Clinical examination was performed to assess SIRS in pyometra dogs and revealed 36.84 per cent (Group I) and 63.16 per cent (Group II) of pyometra affected dogs were SIRS positive. Haematological examination revealed decreased haemoglobin, total erythrocyte count, lymphocyte count along with leucocytosis. DLC revealed neutrophilia with shift to left. Biochemical examination revealed elevated mean serum creatinine (mg/dL), BUN (mg/dL) and CRP (mg/L), hypoalbuminemia and hypochloremia in pyometra dogs with and without azotemia when compared to healthy control while hyponatremia was observed in azotemic bitches. Urinalysis revealed decreased specific gravity and elevation of UPCR, which showed significant difference (P<0.01) between the two groups. The prominent nephrosonographic features observed in azotemic dogs were irregular contour, indistinct cortico-medullary junction, increased/decreased cortical echogenecity and nephrocalcinosis. Doppler ultrasonography was performed to assess haemodynamic changes in kidneys revealed that the mean resistive index (RI) and the mean pulsatility index (PI) were significantly (P<0.01) elevated in pyometra dogs than healthy control. Pearson’s correlation did not demonstrate significant correlation between serum creatinine with RI and PI (P>0.05) in the present study. Significant reduction in the mean±SE of serum creatinine (P<0.01) and mean±SE of serum BUN (P<0.05) following ovario-hysterectomy as compared to pre-operative values suggested that renal dysfunction was transient in most of the pyometra dogs.
