On the third day, glucocorticoid and mineralocorticoid supplementation was begun for the induced adrenocortical insufficiency. The first follow\u2010up examination after completion of the 25\u2010day course and the subsequent twice\u2010yearly follow\u2010up examinations included physical examination and measurements of plasma concentrations of sodium and potassium to optimise substitution therapy. In 19 dogs the full course of 25\u00a0days treatment could not be completed. Of the 110 dogs which received the full course of treatment, the administration had to be stopped temporarily in 32 because of side\u2010effects, such as anorexia and vomiting. The actual dose of o,p\u2018\u2010DDD administered was not significantly different in the dogs with and without these side\u2010effects. Clinical remission occurred in 111 dogs (86 per cent), of which 43 (39 per cent) had a relapse. The estimated one\u2010year disease\u2010free fraction was 77 per cent (95 per cent confidence interval [CI]: 67 to 85 per cent). The estimated one\u2010year survival fraction was 80 per cent (95 per cent ci: 71 to 87 per cent), the two\u2010year survival was 69 per cent (95 per cent ci: 59 to 78 per cent), and the three\u2010year survival was 61 per cent (95 per cent CI: 49 to 71 per cent). The bodyweight and age of the dogs and vomiting occurring during the period of treatment, were positively correlated with the length of the disease\u2010free period, whereas weakness during the treatment and resistance to dexamethasone suppression of the urinary corticoid\/creatinine ratios at the start of the treatment were associated with a relatively short survival time.<\/jats:p>","DOI":"10.1136\/vr.144.1.12","type":"journal-article","created":{"date-parts":[[2010,10,5]],"date-time":"2010-10-05T02:05:51Z","timestamp":1286244351000},"page":"12-17","source":"Crossref","is-referenced-by-count":33,"title":["Results of non\u2010selective adrenocorticolysis by O,p'\u2010DDD in 129 dogs with pituitary\u2010dependent hyperadrenocorticism"],"prefix":"10.1002","volume":"144","author":[{"given":"E.","family":"den Hertog","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences of Companion Animals Faculty of Veterinary Medicine Utrecht University PO Box 80154 3508 TD Utrecht The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
