Ramos GP, Camilleri M. Ten controversies in gastroparesis and a look to the future. Neurogastroenterol Motil 2023; 35:e14494. [PMID: 36371704 PMCID: PMC10133001 DOI: 10.1111/nmo.14494] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 10/17/2022] [Accepted: 10/20/2022] [Indexed: 11/15/2022]
Abstract
BACKGROUND Gastroparesis is a complex, challenging gastrointestinal disorder presenting with upper gastrointestinal symptoms, especially nausea and vomiting, with significant impact on patients' quality of life. After ruling out mechanical obstruction, it is essential to identify delay in gastric emptying for definitive diagnosis. The most common causes are idiopathic (no identified etiology), diabetes mellitus, and postsurgical status. Management of gastroparesis focuses on dietary modifications and treatment directed to symptom relief. Unfortunately, approximately one-third of patients are refractory to pharmacological therapy, and the effectiveness of the few nonpharmacological options has been questioned. PURPOSE Extensive review of the literature identifies several uncertainties or controversies regarding the differential diagnosis based on the spectrum of symptoms, the lack of availability of reliable diagnostic test, and questions regarding effective therapeutic options. In this review, we discuss ten controversies regarding gastroparesis: clinical presentation, diagnosis, overlap syndromes, pathophysiology, etiology, as well as pharmacological and nonpharmacological therapeutic options. In addition, we briefly review studies exploring pathological, inflammatory, and molecular disturbances affecting the intrinsic neuromuscular elements that may be involved in the pathophysiology of gastroparesis and may constitute possible therapeutic targets in the future. Finally, we tabulate future research opportunities to resolve these controversies in the management of patients with gastroparesis.

Abstract
Gastroparesis (GP) is a disorder of gastric functions that is defined by objective delayed gastric emptying in the absence of mechanical obstruction. This disease is characterized by symptoms such as nausea, post-prandial fullness, and early satiety. GP significantly impacts patients' quality of life and contributes to substantial healthcare expenses for families and society. However, the epidemiological burden of GP is difficult to evaluate, mainly due its significant overlap with functional dyspepsia (FD). GP and FD represent two similar diseases. The pathophysiology of both disorders involves abnormal gastric motility, visceral hypersensitivity, and mucosal inflammation. Moreover, both conditions share similar symptoms, such as epigastric pain, bloating, and early satiety. The latest evidence reveals that dysbiosis is directly or indirectly connected to gut-brain axis alterations, which are the basis of pathogenesis in both FD and GP. Furthermore, the role of microbiota in the development of gastroparesis was demonstrated by some clinical studies, which found that the use of probiotics is correlated with improvements in the gastric emptying time (GET). Infections (with viruses, bacteria, and protozoa) represent a proven etiology for GP but have not been sufficiently considered in current clinical practice. Previous viral infections can be found in about 20% of idiopathic GP cases. Moreover, delayed gastric emptying during systemic protozoal infections represents a huge concern for compromised patients, and few data exist on the topic. This comprehensive narrative review analyzes the relationship between microorganisms and GP. We explore, on the one hand, the correlation between gut microbiota dysbiosis and GP pathogenesis, including treatment implications, and, on the other hand, the association between exogenous infections and the etiology of the disease.

Abstract
OBJECTIVES Infectious lumbosacral radiculitis and myelitis, a clinical entity called Elsberg syndrome, is classically linked to HSV-2 and VZV. Here, we report a case of an Elsberg syndrome caused by primary cytomegalovirus (CMV) infection in an immunocompetent patient. METHODS Here is a case report at an academic medical center. Cerebral and spinal cord MRI, electroneuromyography, and serum and CSF analysis were performed. RESULTS We investigated a 31-year-old healthy woman presenting with acute paresthesia of both feet ascending to the pelvic region, urinary retention, and constipation. Neurologic examination revealed symmetrical hyperesthesia of both inferior limbs up to the pelvic region, with patellar and Achilles hyporeflexia. Although MRI was normal, a dysfunction of the S1 left nerve root was observed on electroneurography. CSF analysis was inflammatory. Blood CMV PCR was positive, and anti-CMV IgG/IgM values indicated seroconversion. Taken together, these results strongly suggested an Elsberg syndrome caused by CMV primary infection. After a course of ganciclovir, a marked improvement of the symptoms was observed. DISCUSSION This case highlights that CMV primary infection can be a cause of Elsberg syndrome in immunocompetent patients. CMV testing should be discussed in these patients to initiate adequate antiviral therapy.

Abstract
Background The long-term use of an oral corticosteroid suppresses immunity. Here, we describe a case involving a patient with weakness in the bilateral lower extremities due to cytomegalovirus (CMV) lumbosacral polyradiculitis. Case presentation A 64-year-old man visited a university hospital for symmetric motor weakness in both lower extremities (Medical Research Council grade: 2). Symptoms started 1 month before and gradually aggravated. The patient had been taking oral prednisolone for 10 years in order to control pain in multiple joints due to seronegative rheumatoid arthritis. He also had neuropathic pain on the entire right lower extremity and voiding difficulty. Gadolinium-enhanced magnetic resonance imaging revealed enhancement along the entire lumbosacral nerve roots. In the cerebrospinal fluid analysis (CSF), elevated white blood cell (WBC) count (19 cells/μL) and protein level (142.5 mg/dL) were observed. CMV detection by polymerase chain reaction (PCR) was positive. We diagnosed the patient as having lumbosacral polyradiculitis due to CMV. Ganciclovir (250 mg twice daily) was administered intravenously. Two months after initiating Ganciclovir, in the CSF analysis, CM detection by PCR was negative, and no WBC was found. Conclusion We reported a patient who had symmetric motor weakness in the bilateral lower extremities induced by CMV lumbosacral polyradiculitis. Its occurrence seems to be related to immunosuppresion due to the long-term use of an oral corticosteroid. When a patient who is taking an oral corticosteroid shows motor weakness in the bilateral lower extremities, CMV lumbosacral polyradiculitis is one of the possible disorders to be differentiated.

Abstract
Background Gastroparesis (GP), meaning “gastric palsy”, is a chronic medical condition characterized by delayed or absent gastric emptying in the absence of mechanical obstruction. The primary objective of this study was to determine the patient-specific outcomes and the burden of GP on the US healthcare system. Methods This was a population-based, retrospective study designed to analyze data available from the Nationwide Inpatient Sample (NIS) for 2016 and 2017. Using the International Classification of Diseases, Tenth Revision (ICD-10) codes, we identified adult (18 years or older) hospitalizations with a principal diagnosis of GP. The study sample was further classified into two distinct groups based on the presence or absence of GP, namely diabetic GP (DGP) and non-diabetic GP (NDGP). The primary outcome of our study was inpatient mortality secondary to GP while the secondary outcomes included the odds of system-based complications and the burden of the disease on the United States healthcare system. Results We identified 99,695 adult (≥ 18 years) hospitalizations with a principal discharge diagnosis of GP in 2016 and 2017. Of these patients, 78.1% (77,885) had DGP and 21.9% (21,810) were classified in the NDGP group. We noted a higher proportion of women (79.3% vs. 63.4%, P < 0.001), patients with a history of smoking (35.8% vs. 31.7%, P < 0.001) and chronic obstructive pulmonary disease (10.7% vs. 7.6%, P < 0.001) in the NDGP group. After adjusting for common confounders excluding age, the inpatient mortality for GP was found to be 0.25%. Furthermore, after adjustments were made for the Charlson comorbidity index (CCI), we noted higher odds of mortality in the NDGP group (0.30% vs. 0.23%, adjusted odds ratio (aOR): 3.18, 95% confidence interval (CI): 1.75 - 5.79, P < 0.001) compared to the DGP group. Additionally, patients with NDGP had a higher mean length of stay (5 vs. 4.1 days, P < 0.001) and higher mean total hospital charge ($44,100 vs. $35,500, P < 0.001) compared to those with DGP. The NDGP group also had higher odds of sepsis, deep vein thrombosis (DVT) and pulmonary embolism (PE); however, the odds of developing acute kidney injury (AKI) were lower than that of the DGP group. Conclusions The inpatient mortality for GP was found to be 0.25%. After adjusting for CCI, patients with NDGP had higher odds of inpatient mortality compared to the DGP group. Additionally, patients with NDGP were associated with a longer length of hospital stay, mean total healthcare cost and higher odds of complications such as sepsis, DVT and PE during the hospitalization.

Abstract
Postviral gastroparesis can result from a variety of viral infections and may cause severe, persistent gastrointestinal symptoms. We report the case of an 85-year-old man with one year of persistent nausea, epigastric pain, early satiety, and 25-pound weight loss after an episode of viral gastroenteritis contracted on a cruise ship. The patient reported that he had tested positive for norovirus shortly after the onset of symptoms. Esophagogastroduodenoscopy revealed no abnormalities, and his symptoms persisted despite treatment for a positive serum H. pylori IgG antibody. Lab workup, including hemoglobin A1c, was otherwise normal, and computed tomography (CT) angiography was unremarkable. A gastric emptying study performed one year after the onset of illness revealed moderate gastroparesis. While most cases of postviral gastroparesis resolve within a year or less, there are a few reports of gastroparetic symptoms lasting two to three years or longer. The pathophysiology might involve a slowly reversible injury to gut neuromodulator cells. Antiviral treatment has not been shown to be effective; symptomatic treatment with antiemetic and prokinetic drugs may be helpful in some cases.

Abstract
A 38-year-old lady with advanced human immunodeficiency virus (HIV) infection presented to the emergency department with headache, vomiting and fluctuating alertness for 3 weeks. On examination, she had tachycardia, bilateral papilledema, restriction of upward gaze, gaze-evoked nystagmus and signs of meningeal irritation. Magnetic resonance imaging of the brain showed hydrocephalus and periventricular high T2-signal regions with restriction on diffusion-weighted imaging. Polymerase chain reaction done on the cerebrospinal fluid obtained after the insertion of an external ventricular drain was positive for cytomegalovirus (CMV). She was treated with intravenous ganciclovir followed by oral valganciclovir with which she made a dramatic recovery. CMV ventriculoencephalitis can present with hydrocephalus in HIV-infected individuals. A high index of suspicion must be maintained to diagnose this disease and start appropriate therapy on time.

Abstract
With the introduction of combination antiretroviral therapy, human immunodeficiency virus (HIV)-infected individuals are living longer, and are commonly confronted with chronic neuromuscular complications. The spectrum of neuromuscular disorders in patients living with HIV infection is wide, and is caused by HIV per se and its products, particular antiretroviral drugs, or a combination of both. The purpose of this chapter is to review peripheral nervous system disorders in the setting of HIV infection, and to provide a general approach to diagnosis and management of these disorders. The early identification of these conditions may help with early intervention and management, allow prevention of morbidities associated with these disorders, and contribute to future research efforts in the field of HIV.
