Adrenal Insufficiency Secondary to Peritoneal Dialysis-Related Peritonitis: A Case Report

Peritoneal dialysis (PD)-related peritonitis is one of the most important factors affecting the long-term success of PD. Adrenal insufficiency is a clinical manifestation of inadequate production of glucocorticoids with accompanying deficiency of mineralocorticoids and adrenal androgens. We present a 58-year-old PD patient who admitted to hospital with fever, abdominal pain, vomiting, and confusion. The patient was treated with cephazolin and ceftazidime after the confirmation of peritonitis. Despite the resolution of peritonitis after 2 weeks with appropriate antibiotic treatment, the patient continued to suffer from vomiting, hypotension, and confusion. After the evaluation of basal serum cortisol and 250 mu g ACTH stimulation test, the patient had been diagnosed as adrenal insufficiency and treated with fludrocortisone 0.1 mg/day. Patients remaining vomiting, hypotension, and confusion symptoms were corrected after the fludrocortisone therapy. Following 2 months of successful treatment of adrenal insufficiency, the patient had adherence problem with fludrocortisone for 3-4 weeks. On an outpatient visit, serum ACTH and cortisol levels were normal despite the discontinuation of fludrocortisone and so the patient had been evaluated as partial adrenal insufficiency secondary to PD-related peritonitis. In conclusion, adrenal insufficiency should be kept in mind in PD patients suffering from hypotension and peritonitis.
