Secondary Endpoints
There were no identifiable immediate or delayed adverse drug reactions detected over the 90-day period: no evidence of hemorrhagic and dermatologic adverse effects was noted in any dogs based on clinical signs. A self-limiting diarrhea attributed to the CL loading dose administration was observed in 2 dogs (1 dog in the CL-ULDA group and 1 dog in the CL group), but the frequency of diarrhea was not significantly higher compared with the ULDA group. There was no difference between the treatment groups as to duration of initial hospitalization, transfusion requirements, time of complete hematologic response to therapy, or rate of relapse (Table 2). Cyclosporine was used in 6 dogs (n = 2 in each group) after 14 days of therapy because of persistent anemia and spherocytosis in 4 dogs, and adverse effects of azathioprine in 2 dogs.
