Safe Use of Erythromycin For Refractory Gastroparesis After Small Bowel Transplantation.
    Experimental and clinical transplantation : official journal of the Middle East Society for Organ Transplantation, 2022, Volume: 20, Issue:2

    Current therapeutic options with prokinetic agents for posttransplant gastroparesis are limited. Erythromycin is associated with adverse reactions, including corrected QT interval prolongation and cytochrome P450 3A4 isoenzyme inhibition. The use of erythromycin has been avoided in patients undergoing treatment with cyclosporine or tacrolimus because of significant fluctuations in therapeutic immunosuppression levels. We report herein the successful use of erythromycin after visceral transplant to treat delayed gastric emptying. Two patients were managed with oral erythromycin (initial dose of 750 mg/d divided into 3 doses) for gastroparesis after visceral transplant. Patient 1 was a woman aged 42 years with a history of chronic intestinal pseudo-obstruction syndrome who underwent isolated small bowel transplant with dual (gastric and duodenal) proximal allograft anastomosis. Posttransplant gastroparesis was initially managed with oral metoclopramide. The patient also required high doses of tacrolimus (36 mg/d) to maintain adequate immunosuppression levels. The decision was made to change metoclopramide to erythromycin, which significantly decreased the daily tacrolimus dose requirement (from 36 to 9 mg/d), with resolution of nausea and intermittent bloating symptoms. Patient 2 was a woman aged 35 years with ultra-short gut syndrome after extensive enterectomy due to intestinal volvulus who underwent uneventful combined intestinal and colon transplant. Conventional pharmacologic therapy for gastroparesis was initiated after surgery without success. Erythromycin was started 15 days posttransplant, with significant improvement in her symptoms, and discontinued 47 days post-transplant. To maintain therapeutic levels (8-10 mg/dL), daily tacrolimus dose was decreased 75.8% and 36.5% for patients 1 and 2, respectively. No significant side effects associated with erythromycin use were observed in either patient. Our findings here suggest that erythromycin may be safely used for gastroparesis after small bowel transplant. Close monitoring of immunosuppressive drug levels and dose adjustments of other medications affected by inhibition of cytochrome P450 3A4 are advised.

Gastroparesis following bone marrow transplantation.
    Bone marrow transplantation, 2001, Volume: 28, Issue:1

    Patients often develop nausea, vomiting and bloating after bone marrow transplantation (BMT). These symptoms may interfere with nutrition and the ability to take oral medications. Gastroparesis is a recognized cause of these symptoms in non-transplant patients but less is known about patients who undergo BMT. Between January 1996 and March 1997, a total of 151 patients underwent BMT. Eighteen patients (12%) developed persistent symptoms suggestive of gastroparesis (persistent nausea, vomiting or bloating). Scintigraphic gastric emptying studies were performed to assess for gastroparesis. Prokinetic agents were administered at the time of study. The records on these patients were compared with those of all other patients undergoing BMT during the same time period without these symptoms. Nine patients who demonstrated delayed gastric emptying were further evaluated with esophagastroduodenoscopy and biopsy. Biopsy samples were reviewed for evidence of graft-versus-host disease (GVHD). Fourteen of 18 patients demonstrated delayed gastric emptying and most responded to prokinetic agents given at the time of study. Age, conditioning regimen, cytomegalovirus antigenemia and acute GVHD did not appear to be associated with the development of gastroparesis. Allogeneic BMT recipients were at higher risk than autologous BMT patients (26% vs 0%, P < 0.0001). of allogeneic bmt recipients, there was a nonsignificant trend of patients receiving tacrolimus to be less likely to experience gastroparesis than those receiving cyclosporine (27% vs 48%, P = 0.08). For the nine patients undergoing upper endoscopy, GVHD on gastric biopsy was an uncommon finding and was mild when present. Gastroparesis appears to be a common cause of nausea, vomiting and bloating following allogeneic BMT. This may occur less often with tacrolimus than cyclosporine because of the former agent's prokinetic properties. Patients usually respond to prokinetic drugs at the time of scintigraphy. GVHD and CMV infection do not appear to be major contributing factors.
