ABSTRACT

Objective:

To explore the clinical characteristics, diagnosis and treatment of secondary adrenocortical insufficiency(SACI)after kidney transplantation.

Methods:

Retrospective analysis was conducted for clinical data of 12 recipients with SACI after transplantation from March 2018 to November 2019(observation group). Meanwhile, 10 healthy subjects(control group)were randomly selected for in-hospital physical reexaminations during the same period. General data and morning cortisol levels of adrenocorticotropic hormone(ACTH)and aldosterone were compared between two groups.

Results:

In observation group, there were 8 male and 4 female with an average age of (43.67±8.81) years. Six cases(50.0%)of SACI occurred during recovery period within 30 days and 3 cases(25.0%)within 30 to 90 days post-transplantation. Deceased citizen donation(DCD)was performed in 9 cases(75.0%)and re-transplanted in 3 cases(25.0%). Oral immunosuppressive regiments were administered in a low-dose prednisone-based triple/quadruple regimen. The mean eGFR of observation group was(54.08±20.03)ml/min. The first patient had adrenal crisis, the fourth had sole symptom of fatigue and the remainder stayed asymptomatic. All of them had persistent hyperkalemia and hyponatremia. The average level of plasma cortisol was(62.24±24.16)mmol/L and it was much lower than normal in all patients at 8 am. The determination of plasma ACTH at 8 am showed that 7 patients(58.33%)were lower than normal and the remaining 5 slightly surpassed the low limit of normal. The average level of plasma cortisol at 8 am was significantly lower in observation group than that in control group(141.34±26.28)nmol/L( t=-7.349, P<0.001). The average ACTH level of observation group at 8 am was(1.08±0.515)pmol/l and it was significantly lower than that of control group(2.53±1.06)pmol/L( t=-4.178, P<0.001). The level of aldosterone was normal in both groups and showed no significant difference. All patients in observation group received an intravenous injection of hydrocortisone with satisfactory outcomes.

Conclusions:

Transplant surgeons should be on a high alert for an occurrence of SACI in renal transplant recipients. Serum potassium and sodium levels may be the predictors of SACI.
