Abstract

This pilot study examined associations among patterns of gastric myoelectrical activity, symptoms of gastroparesis, years of diabetes, months of dialysis, and use of gastrointestinal medications in gastroparetic kidney-pancreas (KP) transplant recipients. Electrogastrography (EGG) and gastric symptom data were obtained from 42 transplant recipients before and after transplant (6, 12, and 24 months). Recipients were 38 ± 7 yr of age, 88% Whites, and 60% male; 97% had hypertension. All had functioning grafts post-transplant (mean creatinine, 1.59 ± 0.66 mg/dL, and serum glucose 91.97 ± 24.92 mg/dL). Sixteen subjects had normal EGG (2.7-3.2 cycles per minute, cpm); two were tachygastric (>3.2 cpm) at all time points; one remained bradygastric (<2.7 cpm) throughout the study period. Following transplant, symptoms lessened and were associated with 6-month normalization of EGG (r = 0.41, p = 0.02). A small change in the percentage of patients with normal EGG was observed from baseline to 24 months (67% vs. 69% respectively); however, there was a shift from bradygastria (29% to 15% respectively) to tachygastria (5% to 15% respectively). Prescribed prokinetic and antisecretory medications use increased over the study period from 13 (31%) subjects at baseline to 32 (86%) at 6 months; 21 (78%) at 12 months; and 12 (92%) at 24 months. Although symptoms diminish following transplant, gastroparesis remains a significant problem for transplant patients. Normalization of EGG and shifts from bradygastria to tachygastria occur post-transplant. Our results suggest that serial EGGs and frequent assessment of symptoms can be used to follow gastroparesis in KP recipients.
