BACKGROUND: Kidney pain is a common complication in patients with autosomal
dominant polycystic kidney disease (ADPKD), and data from the TEMPO 3:4 trial
suggested that tolvaptan, a vasopressin V2 receptor antagonist, may have a
positive effect on kidney pain in this patient group. Because pain is difficult
to measure, the incidence of kidney pain leading to objective medical
interventions was used in the present study to assess pain. STUDY DESIGN:
Secondary analysis from a randomized controlled trial. SETTING & PARTICIPANTS:
Patients with ADPKD with preserved kidney function. INTERVENTION: Tolvaptan or
placebo. OUTCOMES: Kidney pain events defined by objective medical interventions.
MEASUREMENTS: Kidney pain events were recorded and independently adjudicated.
Incidence of a first kidney pain event was assessed overall and categorized into
5 subgroups according to severity. RESULTS: Of 1,445 participating patients
(48.4% women; mean age, 39±7 [SD] years; mean estimated glomerular filtration
rate, 81±22mL/min/1.73m(2); median total kidney volume, 1,692 [IQR, 750-7,555]
mL), 50.9% reported a history of kidney pain at baseline. History of urinary
tract infections, kidney stones, or hematuria (all P<0.001) and female sex
(P<0.001) were significantly associated with history of kidney pain. Tolvaptan
use resulted in a significantly lower incidence of kidney pain events when
compared to placebo: 10.1% versus 16.8% (P<0.001), with a risk reduction of 36%
(HR, 0.64; 95% CI, 0.48-0.86). The reduction in pain event incidence by tolvaptan
was found in all groups irrespective of pain severity and was independent of
predisposing factors (P for interaction > 0.05). The effect of tolvaptan was
explained at least in part by a decrease in incidence of urinary tract
infections, kidney stones, and hematuria when compared to placebo. LIMITATIONS:
Trial has specific inclusion criteria for total kidney volume and kidney
function. CONCLUSIONS: Tolvaptan decreased the incidence of kidney pain events
independent of patient characteristics predisposing for kidney pain and possibly
in part due to reductions in ADPKD-related complications.
