Life (Basel) 2024; 14:526. [PMID: 38672796 PMCID: PMC11051147 DOI: 10.3390/life14040526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 04/14/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Peptic ulcer disease (PUD) can cause upper gastrointestinal bleeding (UGIB), often needing esophagogastroduodenoscopy (EGD). Second-look endoscopies verify resolution, but cost concerns prompt research on metoclopramide's efficacy compared to erythromycin. METHODS We analyzed the Diamond Network of TriNetX Research database, dividing UGIB patients with PUD undergoing EGD into three groups: metoclopramide, erythromycin, and no medication. Using 1:1 propensity score matching, we compared repeat EGD, post-EGD transfusion, and mortality within one month in two study arms. RESULTS Out of 97,040 patients, 11.5% received metoclopramide, 3.9% received erythromycin, and 84.6% received no medication. Comparing metoclopramide to no medication showed no significant difference in repeat EGD (10.1% vs. 9.7%, p = 0.34), transfusion (0.78% vs. 0.86%, p = 0.5), or mortality (1.08% vs. 1.08%, p = 0.95). However, metoclopramide had a higher repeat EGD rate compared to erythromycin (9.4% vs. 7.5%, p = 0.003), with no significant difference in transfusion or mortality. CONCLUSIONS The need to repeat EGD was not decreased with pre-EGD use of metoclopramide. If a prokinetic agent is to be used prior to EGD, erythromycin shows superior reduction in the need of repeat EGD as compared to metoclopramide.

Abstract
Gastroparesis, characterized by a decrease in gastric emptying, can lead to worsened diabetes control and a reduced quality of life. The patient was a 32-year-old male with type 2 diabetes. He was initially admitted for control of diabetes, and two months later, he was readmitted due to nausea and vomiting. He showed resistance to various drugs, including antiemetics, and an upper gastrointestinal endoscopy revealed significant gastric residue, leading to a diagnosis of gastroparesis. We administered intravenous erythromycin. After three days of treatment, the vomiting resolved. Gastroparesis is challenging to manage, and there are limited effective treatment options. We experienced a case of diabetic gastroparesis with severe vomiting and loss of appetite that responded remarkably well to intravenous erythromycin treatment. Intravenous administration of erythromycin may be a potentially effective treatment for gastroparesis.

Abstract
INTRODUCTION The global epidemic of diabetes has led to an epidemic of diabetes complications. Diabetic neuropathy is the most common microvascular complication, of which diabetic peripheral neuropathy (DPN) and autonomic neuropathy (AN) are the most prevalent, affecting ~50% of patients. DPN results in pain with a poor quality of life and a loss of sensation with an increased risk of foot ulceration. Autonomic neuropathy can cause significant morbidity in a minority and is associated with increased mortality. The cornerstone of treatment to prevent or limit the progression of DPN/AN is multifactorial risk factor modification including treatment of glycemia, lipids and blood pressure. Whilst, there are no FDA-approved disease-modifying therapies, there are a number of therapies to relieve symptoms in DPN and AN. AREAS COVERED The authors discuss current approved therapies for painful diabetic neuropathy and autonomic neuropathy. They also address the potential role of improving risk factors to limit the development and progression of diabetic neuropathy and new pathogenetic and pain-relieving treatments. EXPERT OPINION The FDA-approved Pregabalin and Duloxetine over 25 years ago and Tapentadol, 6 years ago for painful diabetic neuropathy. There are currently no FDA-approved disease-modifying treatments for diabetic neuropathy which has been attributed to inappropriate models of the disease with limited translational capacity and major limitations of trial designs and endpoints in clinical trials.

Abstract
Ghrelin is a hormone secreted by the stomach during fasting periods and acts through its receptor, the growth hormone secretagogue 1a (GHSR1a), to promote food intake and prevent hypoglycemia. As such, GHSR1a is an important regulator of energy and glucose homeostasis and a target for the treatment of obesity. Here, we showed that the accessory protein MRAP2 altered GHSR1a signaling by inhibiting its constitutive activity, as well as by enhancing its G protein-dependent signaling and blocking the recruitment and signaling of β-arrestin in response to ghrelin. In addition, the effects of MRAP2 on the Gαq and β-arrestin pathways were independent and involved distinct regions of MRAP2. These findings may have implications for the regulation of ghrelin function in vivo and the role of MRAP2 in energy homeostasis. They also show that accessory proteins can bias signaling downstream of GPCRs in response to their endogenous agonist.

Abstract
Introduction Cardiovascular autonomic neuropathy (CAN) and gastroparesis are two types of diabetic autonomic neuropathy which could affect patients' quality of life and carry significant morbidity and mortality outcomes. The aim of this study was to estimate the prevalence and risk factors of both CAN and gastroparesis symptoms among patients with type 2 diabetes mellitus (T2DM) at primary health care level. Methods A cross-sectional study was conducted among 400 adults with T2DM from April 1, 2017 to March 20, 2018. CAN was defined by the presence of any of the followings: resting tachycardia, orthostatic hypotension or prolonged corrected QT interval in the electrocardiogram. Gastroparesis symptoms were assessed using a validated questionnaire: the Gastroparesis Cardinal Symptom Index. Results The mean age of study participants and disease duration were 55.26 ± 10.65 years and 10.77 ± 6.89 years, respectively. CAN was present in 15.3% of the participants. Hypertension, smoking, antihypertensive use, body mass index, dyslipidemia and albuminuria were significantly higher in participants with CAN than those without CAN (p<0.05). Prolonged disease duration (p = 0.007) and hypertension (p = 0.004) were independently associated with CAN. Gastroparesis symptoms were present in 6.3% of study participants and were significantly associated with those of female gender (P<0.05). Metformin use emerged as an independent predictor of the presence of at least one symptom (p = 0.001). Conclusion Among Saudi adults with T2DM at primary care level, the prevalence of CAN is significant and is independently related to disease duration and hypertension, indicating the importance of CAN screening, especially for those with prolonged disease duration, and the importance of controlling blood pressure in order to prevent CAN or its consequences. The prevalence of gastroparesis symptoms is 6% and is independently related to metformin use, and therefore, symptomatic screening is required to decide which patients need further evaluation.

Abstract
Our previous work demonstrated that the C-type natriuretic peptide (CNP)/cyclic guanosine monophosphate (cGMP)/cyclic adenosine monophosphate (cAMP) pathway in gastric antrum smooth muscle of rats with diabetes was upregulated and played an important role in the development of diabetic gastric dysmotility. Our goal for this study was to explore the downstream signaling pathways of CNP. We found that the expressions of protein kinase G (PKG) and protein kinase A (PKA) in gastric smooth muscle tissue of rats with diabetes were significantly upregulated. The expressions of β-type phospholipase C 3(PLCβ3) and β-type phospholipase C 1(PLCβ1) protein were reduced, whereas Phosphor-PLCβ3Ser1105 (P-PLCβ3Ser1105) was increased. The inhibitory effect of CNP on gastric antral smooth muscle in diabetic rats was significantly greater than in the normal group. The content of trisphosphate inositol (IP3) in the gastric antral smooth muscle of rats with diabetes was significantly lower than that of the normal group. After blocking PKA with N-[2-(p-Bromocinnamylamino)ethyl]-5-isoquinolinesulfonamide dihydrochloride (H-89, a blockage PKA), the effect of CNP on the production of IP3 was decreased, while blocking PKG with KT5823 (a blockage PKG) simultaneously, and CNP can no longer reduce the IP3 production. CNP promoted the phosphorylation of PLCβ3Ser1105, thereby inhibiting the activity of PLCβ3 in gastric smooth muscle tissue of rats with diabetes; this effect can be abolished by blocking PKA and PKG. These results suggested that CNP can decrease IP3 level in gastric smooth muscle cells and thus inhibit gastric smooth muscle contraction through PKG/PKA-PLCβ pathway, which may play an important role in the development of diabetic gastroparesis.

Abstract
Diabetic gastroparesis (DGP), a delay in gastric emptying without obstruction to outflow as a complication of diabetes, typically develops after at least 10 years of diabetes. Cardinal symptoms include nausea, vomiting, early satiety, bloating, and upper abdominal pain. The aim of DGP treatment is to alleviate the severity and frequency of symptoms, improve the level of gastric emptying, ameliorate the patient's nutritional status and to optimize glycemic control. In the treatment of chronic drug-refractory nausea and vomiting secondary to DGP, gastric electrical stimulation (GES) such as Enterra Therapy System (Medtronic Inc., Minneapolis, MN, USA) can be considered. It is well established that diabetic nephropathy is the most common cause of end-stage renal disease (ESRD) requiring renal replacement therapy. The exact prevalence of patients with severe DGP and ESRD is not known; however, finding a therapeutic approach to these patients, particularly those whose gastroparesis symptoms preclude them from undergoing kidney transplant procedure, represents a huge challenge. Our experience suggests that GES implantation can be an effective treatment modality for type 1 diabetic patients on peritoneal dialysis (PD) who are simultaneous pancreas-kidney transplantation candidates, by improving the severity and frequency of gastroparesis symptoms and eventually ensuring their optimal nutritional and fluid intake.

Abstract
PURPOSE This review provides an update on the investigations and treatment options for gastroparesis. METHODS A comprehensive literature search of Medline, PubMed, Embase and OVID was conducted which included all systematic reviews and research articles that focused on the diagnosis, investigations and management diabetic gastroparesis. FINDINGS Dietary modifications and pharmacologic treatment with prokinetics to increase gastric motility form the mainstay of treatment. However, the use of prokinetics is limited by adverse effects and serious adverse effects, leaving metoclopramide as the only drug approved by the US Food and Drug Administration for the treatment of gastroparesis. Newer therapies, including motilin receptor agonists, ghrelin receptor agonists, and neurokinin receptor antagonists, are currently being investigated. Transpyloric stenting, gastric electrical stimulation, and gastric per-oral endoscopic myotomy provide mechanical options for intervention, and surgical interventions in severe intractable gastroparesis include laparoscopic pyloroplasty or gastrectomy. IMPLICATIONS Advances to better understand the pathophysiology and management of diabetic gastroparesis have been limited, especially with discordance between symptoms and severity of delay in gastric emptying. Established treatment options are limited; however, recent pharmacologic and surgical interventions show promise.

Abstract
Hereditary transthyretin amyloidosis (ATTRm amyloidosis) is a rare disease caused by the deposition and accumulation of insoluble non-native transthyretin fibrils in the body. The disease inevitably results in widespread organ disruption, and poor life expectancy. The GI tract is one organ system vulnerable to disruption and, although the clinical presentation of the disease varies, GI involvement affects most patients with ATTRm amyloidosis. Areas covered: This article presents our experience with diagnosing and treating the GI symptoms of ATTRm amyloidosis patients at our center over the last 40 years, in the Swedish clustering area of the disease. Our aim is to help other physicians to better manage GI complications in patients with this rare but widespread condition. Expert commentary: GI symptoms are debilitating complications for ATTRm amyloidosis patients to experience, yet with the appropriate questioning and diagnosis methods, symptomatic treatments of these symptoms can be implemented to provide relief. Further, patients with fewer GI complications and a good nutritional status are also better candidates for liver transplantation which, in selected cases, is the best disease-modifying treatment of ATTRm amyloidosis to date.

Abstract
Introduction: Domperidone is a dopamine receptor antagonist with peripheral prokinetic and central antiemetic properties. Prolongation of the QTc interval with chronic use of oral domperidone in standard doses has been reported in the literature. Our goal was to investigate cardiac toxicity in patients receiving 2-fold greater doses than in previous reports. Methods: A retrospective chart review was conducted of patients with nausea (N) and vomiting (V) receiving domperidone from 2009 to 2013 under an Investigational New Drug (IND) protocol. Patient demographics, indications for therapy, clinical outcomes, cardiac symptoms and electrocardiogram tracings were reviewed. Prolonged QTc was verified if >470 milliseconds in females (F) and >450 milliseconds in males (M). Results: A total of 64 patients, 44 female (37% Hispanic, 60% white, 3% African American), were taking domperidone for diabetic gastroparesis 45%; idiopathic gastroparesis 36%; chronic N&V 8%; dumping syndrome 5%; cyclic vomiting 5% and conditioned vomiting 1%. Mean duration of therapy was 8 months (range, 3 months to 4 years). Doses ranged from 40 to 120 mg/d with 90% receiving 80 to 120 mg compared with the standard dose of 40 mg. Of note, 73% of subjects benefited from treatment with reduced nausea and vomiting. Thirty-seven patients had follow-up electrocardiograms available, and they showed that the mean QTc at baseline was 424 milliseconds ± 28.4 (SD) compared with 435 milliseconds ± 27.2 (SD) at follow-up (not significant). Ten of these patients had prolonged QTc at F/U ranging from 453 to 509 milliseconds, without any cardiovascular complaints. There was no relationship between prolonged QTc and daily dose of domperidone, body mass index or age. Conclusions: Our data indicate that at very high dosing, the prokinetic/antiemetic agent domperidone has a low risk of adverse cardiovascular events while exhibiting good clinical efficacy.

Abstract
OBJECTIVES The aim of the present study was to develop an ultrasonographic approach to comparatively assess gastric emptying in newborn wild-type and guanosine triphosphate cyclohydrolase knockout hph-1 mice, because we previously reported gastroparesis early in life in this strain. METHODS Stomach transverse, anteroposterior, and longitudinal ultrasonographic measurements were obtained with a 40-MHz transducer in pups immediately after maternal separation and 4 hours later. A conventional equation was used and the predicted values validated by obtaining postmortem gastric content volume measurements. Wild-type and hph-1 mice gastric emptying rates were comparatively evaluated at 1 to 3 and 5 to 8 days of age, respectively. RESULTS The ultrasound equation closely predicted the newborn stomach content volumes with a correlation coefficient (R) of 0.93 and 0.81 (P < 0.01) for measurements obtained on full stomach and after 4 hours of fasting, respectively. In wild-type mice, gastric emptying was age dependent and associated with a greater residual volume at 1 to 3 days (65% ± 7%), as compared with 5- to 8-day-old pups (33% ± 4%; P < 0.01), after fasting. In contrast, an equal duration of fasting resulted in a significantly greater residual gastric content volume in 5- to 8-day-old hph-1 mice (68% ± 7%; P < 0.01), as compared with same-age wild-type mice. CONCLUSIONS Ultrasonography offers a sensitive and accurate estimate of gastric content volume in newborn mice. In wild-type newborn mice, gastric emptying rate is age dependent and significantly reduced in the immediate postnatal period. The newborn hph-1 mice have a significantly higher gastric residual volume, as compared with wild-type same-age animals.

Abstract
BACKGROUND Domperidone, an effective prokinetic agent, is commonly used to manage symptoms of gastroparesis. Health regulatory agencies have issued warnings about an increased risk of sudden cardiac death associated with use of this drug. OBJECTIVE To evaluate the evidence for domperidone-associated sudden cardiac death and to determine whether this drug can be safely used for gastroparesis in patients undergoing dialysis. DATA SOURCES Two databases (MEDLINE [1965 to September 2014] and Embase [1980 to September 2014]) were searched using the Medical Subject Headings "domperidone", "sudden cardiac death", and "cardiac arrhythmia". The search was limited to studies conducted in humans and published in English. Advisories from health regulatory agencies (Health Canada, the European Medicines Agency, and the US Food and Drug Administration) were identified and reviewed. STUDY SELECTION Studies eligible for inclusion in this narrative review were randomized controlled trials and cohort, case-control, cross-sectional, and other epidemiological studies comparing use and non-use of domperidone for the outcome of sudden cardiac death in adults. Abstracts of eligible case reports and case series were also included. DATA SYNTHESIS Despite inconsistencies in their decisions, the various drug regulatory authorities have acknowledged the potential safety concern of increased risk of sudden cardiac death associated with domperidone. To date, no randomized controlled studies have shown an increased risk of this outcome secondary to domperidone use. Current regulatory recommendations and approval decisions are based on 2 large observational epidemiological studies that generated a signal of increased risk. The strengths and limitations of these studies were evaluated in detail. No direct evidence applicable to patients with end-stage renal disease was found. In vitro evidence suggests that the risk of sudden cardiac death is dose-related. CONCLUSIONS Given gaps in the literature, use of domperidone for patients undergoing dialysis should be assessed on a case-by-case basis. Extreme caution should be used for patients taking more than 30 mg/day of this drug.

Abstract
AIM: To assess the clinical effects of trimebutine maleate combined with domperidone in the treatment of diabetic gastroparesis (DGP).
METHODS: Eighty-six patients with DGP were randomly divided into either an experiment group or a control group. The experiment group was treated with trimebutine maleate combined with domperidone, and the control group was treated with domperidone alone. The clinical effects, gastric emptying half-time (GET1/2), adverse reactions, and relapse were compared for the two groups.
RESULTS: The total effective rate for the experiment group was significantly higher than that for the control group (93.02% vs 74.42%, P < 0.05). The GET1/2 post-treatment for the two groups was significantly lower than that prior-treatment (124.49 min ± 23.05 min vs 225.62 min ± 21.88 min, 199.46 min ± 23.49 min vs 222.62 min ± 19.08 min, P < 0.05). There was no significant difference in the rate of adverse reactions for the two groups (0.00% vs 4.65%, P > 0.05). The rate of relapse at 2 mo for the experiment group was lower than that for the control group (13.95% vs 51.16%, P < 0.05).
CONCLUSION: Trimebutine maleate combined with domperidone can improve clinical symptoms and GET1/2 in patients with DGP.

Preclinical gastrointestinal prokinetic efficacy and endocrine effects of the ghrelin mimetic RM-131. Life Sci 2014; 109:20-9. [PMID: 24931905 DOI: 10.1016/j.lfs.2014.06.003] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2014] [Revised: 05/28/2014] [Accepted: 06/03/2014] [Indexed: 12/11/2022]
Abstract
AIMS The 28 amino acid hormone ghrelin, the natural ligand for the growth hormone secretagogue, or ghrelin receptor (GHR), has diverse physiological functions, including a possible role as a gastrointestinal prokinetic. The synthetic ghrelin mimetic RM-131 is in Phase II clinical trials for treatment of diabetic gastroparesis and other gastrointestinal (GI) disorders. We aimed to determine the relative potency of RM-131, when compared to other GI ghrelin mimetics, to predict efficacy and determine the role of RM-131 in models of inflammatory bowel disease. MAIN METHODS We evaluated and compared ghrelin, RM-131 and other synthetic ghrelin mimetics for their prokinetic potency in models of gastrointestinal disorders in the rat and we evaluated the endocrine (rats and dogs) and anti-inflammatory effects (mice) of the ghrelin mimetic RM-131. KEY FINDINGS The pentapeptide RM-131 increased gastric emptying in rodent models of ileus. RM-131 is about 100-fold more potent than human ghrelin and is 600 to 1800-fold more potent, when compared to several investigational ghrelin mimetics tested in clinical trials. RM-131 has anti-inflammatory effects and significantly increases survival and reduces macroscopic markers of tissue damage in a TNBS model of inflammatory bowel disease. RM-131 treatment shows a transient increase in growth hormone levels in Beagle dogs and rats, returning to baseline upon chronic treatment. Significant effects on glucose and insulin are not observed in chronic studies. SIGNIFICANCE RM-131's potency, efficacy and endocrine profile, are promising attributes for the treatment of diverse functional gastrointestinal disorders in humans.
