Pre- and Post-Transfusion Alloimmunization in Dogs Characterized by 2 Antiglobulin-Enhanced Cross-match Tests.

ABSTRACT: When dogs are transfused, blood compatibility testing varies widely but may include dog erythrocyte antigen (DEA) 1 typing and rarely cross-matching.Prospective study to examine naturally occurring alloantibodies against red blood cells (RBCs) and alloimmunization by transfusion using 2 antiglobulin-enhanced cross-match tests.Eighty client-owned anemic, 72 donor, and 7 control dogs.All dogs were typed for DEA 1 and some also for DEA 4 and DEA 7. Major cross-match tests with canine antiglobulin-enhanced immunochromatographic strip and gel columns were performed 26-129 days post-transfusion (median, 39 days); some dogs had an additional early evaluation 11-22 days post-transfusion (median, 16 days). Plasma from alloimmunized recipients was cross-matched against RBCs from 34 donor and control dogs.The 2 cross-match methods gave entirely concordant results. All 126 pretransfusion cross-match results for the 80 anemic recipients were compatible, but 54 dogs died or were lost to follow up. Among the 26 recipients with follow-up, 1 dog accidently received DEA 1-mismatched blood and became cross-match-incompatible post-transfusion. Eleven of the 25 DEA 1-matched recipients (44%) became incompatible against other RBC antigens. No naturally occurring anti-DEA 7 alloantibodies were detected in DEA 7- dogs.The antiglobulin-enhanced immunochromatographic strip cross-match and laboratory gel column techniques identified no naturally occurring alloantibodies against RBC antigens, but a high degree of post-transfusion alloimmunization in dogs. Cross-matching is warranted in any dog that has been previously transfused independent of initial DEA 1 typing and cross-matching results before the first transfusion event.

Project description:Introduction:Sexual dysfunction is a common problem in patients with chronic kidney disease. Disturbances in sexual function are noticed in early stages of chronic kidney diseases and deteriorate further as renal function declines. This is due to uremic effects, comorbid illness, anemia, hormonal disturbances, autonomic neuropathy, vascular diseases, hyperparathyroidism, hyperprolactinemia, side effects of medications, and psychosocial factors. Patients and method:This is a cross-sectional study which included 59 male patients who underwent renal transplantation for more than 6 months. The International Index of Erectile Function (IIEF-5) was adopted in our study to record the erectile function. Results:The mean age was 49.41 years, and the mean number of hemodialysis per month was 5.31. The cause of the chronic kidney disease was diabetes mellitus in 35.59%, glomerulonephritis in 20.34%, and hypertension in 16.95%, other causes were diagnosed in order of decreasing frequency. Most patients developed improvement in the erectile function after transplantation. There was significant correlation with 3 of the elements of the IIFE-5.i.e; penile hardness pre-penetration, Maintaining erection during intercourse, and Difficulty to maintain erection to complete the intercourse (p values 0.015, 0.011, and 0.023) respectively, and the overall improvement after transplantation which showed a p-value of less than 0.031, while there was no significant correlation with Confidence with erection and Satisfaction with intercourse before and after transplantation (p values 0.113 and 0.121) respectively. One of the patients (1.7%) developed severe dysfunction after that. Conclusion:ED is common sequel of chronic kidney disease. The etiology is multifactorial and may be worsen by advanced age, presence of diabetes mellitus and prolonged duration of hemodialysis. Renal transplantation has a positive impact on sexual function and lead to improvement of erectile dysfunction. Erectile dysfunction that persists after kidney transplantation is usually attributed to multiple preexisting comorbidities.

Project description:BackgroundThe use of salivary biomarkers has garnered attention because the composition of saliva reflects the body's physiological state. Saliva contains a wide range of components, including peptides, nucleic acids, electrolytes, enzymes, and hormones. It has been reported that salivary alpha-amylase and cortisol are biomarkers of stress related biomarker in diseased dogs; however, evaluation of salivary alpha-amylase and cortisol pre- and post- operation has not been studied yet. The aim of this study was to evaluate salivary alpha-amylase and cortisol levels in dogs before and after they underwent surgery and investigate the association between the salivary alpha-amylase and cortisol activity and pain intensity. For this purpose, a total of 35 dogs with disease-related pain undergoing orthopedic and soft tissue surgeries were recruited. Alpha-amylase and cortisol levels in the dogs' saliva and serum were measured for each using a commercially available canine-specific enzyme-linked immunosorbent assay kit, and physical examinations (measurement of heart rate and blood pressure) were performed. In addition, the dogs' pre- and post-operative pain scores determined using the short form of the Glasgow Composite Measure Pain Scale (CMPS-SF) were evaluated.ResultsAfter surgery, there was a significant decrease in the dogs' pain scores (0.4-fold for the CMPS-SF, p < 0.001) and serum cortisol levels (0.73-fold, p < 0.01). Based on their pre-operative CMPS-SF scores, the dogs were included in either a high-pain-score group or a low-pain-score group. After the dogs in the high-pain-score group underwent surgical intervention, there was a significant decrease in their CMPS-SF scores and levels of salivary alpha-amylase, serum alpha-amylase, and serum cortisol. Additionally, there was a positive correlation between salivary alpha-amylase levels and CMPS-SF scores in both the high- and low-pain-score groups.ConclusionsThe measurement of salivary alpha amylase can be considered an important non-invasive tool for the evaluation of pain-related stress in dogs.
