RESUMEN
Portal hypertension has cerebral consequences via its causes and complications, namely hepatic encephalopathy (HE), a common and devastating brain disturbance caused by liver insufficiency and portosystemic shunting. The pathogenesis involves hyperammonemia and systemic inflammation. Symptoms are disturbed personality and reduced attention. HE is minimal or grades I to IV (coma). Bouts of HE are episodic and often recurrent. Initial treatment is of events that precipitated the episode and exclusion of nonhepatic causes. Specific anti-HE treatment is lactulose. By recurrence, rifaximin is add-on. Anti-HE treatment is efficacious also for prophylaxis, but emergence of HE marks advanced liver disease and a dismal prognosis.

BACKGROUND: The aim was to examine rifaximin plus lactulose efficacy in patients with cirrhosis at a risk of developing overt HE who were stratified by important baseline characteristics such as comorbid ascites or diabetes. METHODS: Pooled post hoc subgroup analysis of adults receiving rifaximin 550 mg twice daily plus lactulose or lactulose alone for 6 months in a phase 3 randomized, double-blind trial and a phase 4 open-label trial was conducted. RESULTS AND CONCLUSION: Rifaximin plus lactulose was more efficacious than lactulose alone for reducing the risk of overt HE recurrence and HE-related hospitalization in adults grouped by select baseline disease characteristics.

BACKGROUND: Functional constipation (FC) is a common condition in children, and information on the clinical characteristics of FC in Saudi children is scarce. OBJECTIVE: Describe the clinical profile of FC in Saudi children. DESIGN: Retrospective. SETTING: Hospital that provides primary, intermediate and tertiary care. PATIENTS AND METHODS: All children diagnosed with FC according to the Rome IV criteria were included and had at least one follow-up clinic visit. Demographic and clinical data collected from medical records included the age at onset, duration of constipation, clinical features, treatment modalities, and factors associated with clinical response. Descriptive statistics and Pearson's chi-squared test were used in the statistical analysis to see how categorical study variables were linked to clinical response. A P value of ≤.05 was used to report statistical significance. MAIN OUTCOME MEASURE: Compliance and clinical response to polyethylene glycol (PEG) compared with lactulose. SAMPLE SIZE: 370 children from 0.1 to 13 years of age. RESULTS: The median (IQR) age of onset was 4 (5) years and less than one year in 14%. The median (IQR) duration of constipation was 4 months (11) and less than two months in 93/370 (25%). Abdominal pain was the most commonly associated feature (44%). Screening for celiac disease and hypothyroidism was negative. A Fleet enema was the most common disimpaction method (54%) and PEG was the most common maintenance medication (63.4%). PEG was significantly better tolerated (P=.0008) and more effective than lactulose (P<.0001). Compliance was the only variable significantly associated with clinical response. CONCLUSIONS: PEG was better tolerated and more effective than lactulose in our study, a finding in agreement with the literature. Therefore, PEG should be the drug of choice in the initial management of FC in Saudi children. Prospective studies on the causes of noncompliance are needed to improve the response to treatment. LIMITATIONS: The limitations of retrospective design are missing data, recall bias, and hospital-based limitation, such as missing milder cases treated at the outpatient level. However, the sample size of 370 may have minimized these limitations.

BACKGROUND: Over 50% of hospitalizations from hepatic encephalopathy (HE) are preventable, but patients often do not receive medical treatment. AIMS: To use a multimodal education intervention (MMEI) to increase HE treatment rates and to evaluate (1) trends in HE treatment, (2) predictors of receiving treatment, and (3) the impact of treatment on hospitalization outcomes. METHODS: Prospective single-center cohort study of patients hospitalized with HE from April 1, 2020-September 30, 2022. The first 15 months were a control ("pre-MMEI"), the subsequent 15 months (MMEI) included three phases: (1) prior authorization resources, (2) electronic order set, and (3) in-person provider education. Treatment included receiving any drug (lactulose or rifaximin), or combination therapy. Treatment rates pre- vs. post-MMEI were compared using logistic regression. RESULTS: 471 patients were included. There were lower odds of receiving any drug post-MMEI (p = 0.03). There was no difference in receiving combination therapy pre- or post-MMEI (p = 0.32). Predictors of receiving any drug included alcohol-related or cryptogenic cirrhosis (p's < 0.001), and the presence of ascites (p = 0.005) and/or portal hypertension (p = 0.003). The only significant predictor of not receiving any drug treatment was having autoimmune cirrhosis (p < 0.001). Patients seen by internal medicine (p = 0.01) or who were intoxicated (p = 0.02) were less likely to receive rifaximin. Any treatment was associated with higher 30-day liver disease-specific readmission (p < 0.001). CONCLUSION: This MMEI did not increase HE treatment rates, suggesting that alternative strategies are needed to identify and address barriers to treatment.

Hepatic encephalopathy is a common cause of morbidity and mortality among patients with decompensated liver cirrhosis. In this article, we review the history, mechanism, and evidence for first-line pharmacologic therapies for hepatic encephalopathy including nonabsorbable disaccharides, antibiotics, and electrolyte management. We also review newer, second-line therapies including polyethylene glycol, albumin, branched-chain amino acids, probiotics and fecal microbiota transplant, zinc, and l-ornithine-l-aspartate.

The pathophysiology of hepatic encephalopathy (HE) is complex, with hyperammonemia playing a central role in its development. Traditional therapies for HE have targeted ammonia and include medications such as lactulose and rifaximin. Although these agents are considered standard of care, nontraditional treatments seek to affect other factors in the pathogenesis of HE. Finally, procedural therapies include albumin dialysis, shunt closure, and the ultimate cure for HE, which is liver transplant. The treatments discussed provide alternative options for patients who have failed standard of care. However, more high-quality studies are needed to routinely recommend many of these agents.

Hepatic veno-occlusive disease (VOD)/sinusoidal obstructive syndrome (SOS) is a severe complication that can occur following haematopoietic stem cell transplant (HSCT) with high-intensity conditioning chemotherapy regimens. Severe VOD/SOS, often characterised by multiorgan failure, is associated with a high mortality rate. This case report details the complex clinical course of a male patient in his mid-20s, recently diagnosed with B cell acute lymphoblastic leukaemia, who underwent allogeneic HSCT. Based on the 2023 European Society for Blood and Marrow Transplantation (EBMT) criteria, the patient developed very severe VOD/SOS, prompting immediate treatment with defibrotide. Unexpectedly, he developed profound hyperammonaemia exceeding 900 µmol/L, leading to encephalopathy and cerebral oedema. Despite aggressive interventions including defibrotide, lactulose, rifampin and haemodialysis, the patient passed away due to cerebral oedema and pulseless electrical activity arrest. We theorise the hyperammonaemia is disproportionate to his hepatic dysfunction and is possibly secondary to an acquired defect of the urea synthesis consistent with idiopathic hyperammonaemia, a rare complication in patients receiving intense conditioning chemotherapy.

Hepatic encephalopathy is described by a broad spectrum of neurological and psychiatric aberrations resulting due to advanced liver dysfunction. It is a neurological disorder due to hepatic insufficiency and/or portosystemic shunts. Its clinical presentation includes neuropsychiatric dysfunction ranging from subclinical changes to comatose state. It is a sign of poor prognosis in cirrhotics with a high 1-year mortality. Each episode of hepatic encephalopathy leads to high hospitalization rate, poor prognosis and raised burden of healthcare. Primary prophylaxis is prevention of initial occurrence and secondary prophylaxis is prevention of reappearance of hepatic encephalopathy in subjects who had prior history. Early detection and management of triggers is very important in the treatment of hepatic encephalopathy. The initial choice of treatment is still lactulose, as it is effective in minimal, overt, and recurrent hepatic encephalopathy. Rifaximin is equally effective as lactulose in managing hepatic encephalopathy and is better tolerated. Branch chain amino acids are beneficial in subjects who are protein intolerant. L-ornithine L-aspartate and probiotics are also useful in the management of hepatic encephalopathy. Rifaximin along with lactulose is effective in managing overt and recurrent hepatic encephalopathy. Large portosystemic shunts embolization and liver transplant is efficacious in certain group of patients. Nutritional therapy and fecal microbiota transplantation are newer therapies for hepatic encephalopathy but the evidences are limited, more research is required to prove their efficacy. Involvement of hospital pharmacists, telemedicine, and providing education are also beneficial in managing hepatic encephalopathy.

OBJECTIVE: To compare polyethylene glycol 4000 versus lactulose in chronic constipation during pregnancy. METHODS: Women at 28-32 weeks' gestation attending antenatal clinic for routine care were screened using the Rome IV chronic constipation criterion. Eligible women were approached and consented. Participants were randomized to oral polyethylene glycol (10 g/day) or lactulose (10 g/day) for 4 weeks. A bowel movement diary was kept and outcomes using the Patient Assessment of Constipation Symptoms questionnaire (PAC-SYM), Patient Assessment of Constipation Quality of Life questionnaire (PAC-QoL) and Bristol Stool Form Scale (BSFS), which were evaluated at the start and end of the four-week period. Relative risks (RR) were determined for the coprimary outcomes of complete spontaneous bowel movement (CSBM) and PAC-SYM mean score improvement (decrease in score of >1 from the baseline). RESULTS: A total of 4323 women underwent screening, of which 780 fulfilled the Rome IV criterion, and 360 consented to participate (180 randomized to PEG and lactulose, respectively). Data from 247 women who completed the study were analyzed. CSBM was achieved in 107/124 (86.3%) versus 102/123 (82.9%) (RR 1.04, 95% CI: 0.93-1.16, P = 0.464) for PEG and lactulose trial arms, respectively. PAC-SYM mean score improvement was 62/118 (52.5%) in the PEG arm versus 44/118 (37.3%) in the lactulose arm (RR 1.40, 95% CI: 1.05-1.88). Of secondary outcomes, a significant difference was found in favor of PEG, with respect to PAC-SYM abdominal symptoms subscale, normal stool versus loose stool consistency and side effects of vomiting and diarrhea. After controlling for parity, baseline PAC-SYM, PAC-QoL scores, characteristics different at baseline, only diarrhea and loose stools remained significant. CONCLUSION: Both PEG 4000 and lactulose are effective laxatives in pregnancy with similar performance after adjusted analysis. Diarrhea and loose stools are less frequently reported with PEG.

BACKGROUND: The relationship between Helicobacter pylori (H. pylori) infection and small intestinal bacterial overgrowth (SIBO) has attracted attention recently. AIMS: To analyze the influence of H. pylori infection and eradication on SIBO, IMO, and abdominal symptoms. METHODS: Patients with gastrointestinal symptoms were tested for 13C urea breath test and if positive, treated with bismuth-based quadruple therapy. Lactulose hydrogen methane breath test (HMBT) was performed and symptoms were assessed using gastrointestinal symptom rating scale (GSRS) before and 6 weeks after eradication. RESULTS: Of the 102 subjects, 53 were H. pylori positive. The prevalence of SIBO and IMO were higher in patients with H. pylori infection than in those without infection (49.1% vs 24.5%, P = 0.019 for SIBO; 24.5% vs 8.2%, P = 0.027 for IMO). GSRS scores were similar between H. pylori-infected and uninfected patients (2 (IQR: 1;3) vs 2 (IQR: 1;2), P = 0.211). Patients with SIBO or IMO presented higher GSRS scores than patients with both SIBO and IMO negative (2 (IQR: 2;3), 2 (IQR: 2;3) vs 2 (IQR: 1;2), P = 0.011, 0.001, respectively). For the 50 patients who successfully eradicated H. pylori, the response rates for SIBO and IMO were 66.7% and 76.9%, respectively. GSRS scores also significantly decreased (2 (IQR: 1;3) to 0 (IQR: 0;1), P < 0.001) after eradication. CONCLUSION: Helicobacter pylori infection was associated with higher prevalence of SIBO and IMO, both of which led to more pronounced abdominal symptoms. H. pylori eradication also achieved therapeutic effects on SIBO and IMO, accompanied by relief of abdominal symptoms.

OBJECTIVES: Adolescent and pediatric functional constipation (FC) is a common clinical problem. Currently, data on lubiprostone for the treatment of pediatric FC are scarce. This study investigated the efficacy and safety of lubiprostone in the treatment of pediatric FC. METHODS: In a single-blinded, randomized controlled study, we included 280 patients aged 8-18 years with FC. Patients were randomized either to a weight-based lubiprostone dose (n = 140) or conventional laxatives (n = 140), including lactulose, bisacodyl, or sodium picosulfate, for 12 weeks, followed by 4 weeks posttreatment follow-up. RESULTS: Improvement in constipation was achieved in 128 (91.4%) patients in the lubiprostone group, and in 48 (34.3%) patients of the conventional therapy group (p < 0.001) and was sustained after treatment discontinuation. One quarter of the lubiprostone group experienced the first spontaneous bowel motion within 48 h after dose initiation. A total of 75.7% of the lubiprostone group could achieve and sustain Bristol stool form of 3 or 4 during the last 4 weeks of therapy and through the 4 weeks of follow-up versus 50 (35.7%) patients in the conventional therapy group (p < 0.001). No life-threatening adverse drug reactions were encountered, and no treatment-related discontinuation. Mild self-limited colicky abdominal pain and headache were the most prevalent side effects in the lubiprostone group. CONCLUSIONS: Lubiprostone is an effective and well-tolerated pharmacotherapy for youthful age and pediatric age groups, which may alter the paradigm of pediatric FC treatment.

Hepatic encephalopathy (HE) is one of the major complications of liver disease and significantly affects the quality of life (QOL) of patients. HE is common and frequently relapses in cirrhotic patients. The management of HE is supportive, and precipitating conditions should be eliminated. Most drugs used to treat HE are conventional and include nonabsorbable disaccharides such as lactulose, and antibiotics such as rifaximin. However, their therapeutic efficacy is still suboptimal, and novel therapeutic agents are urgently needed. In addition, the optimal management and diagnosis of minimal HE/covert HE are under debate. In this review, we focus on novel pathogenetic mechanisms such as central nervous system clearance, and emerging therapeutic targets of HE, such as fecal material transplantation. We also discuss different classifications and etiologies of HE.

Lactulose-based hepatic encephalopathy treatment requires bowel movements/day titration, which is improved with Bristol stool scale (BSS) incorporation. Dieta app evaluates artificial intelligence (AI)-based BSS (AI-BSS) with stool images. Initially, controls (N = 13) and cirrhosis patients on lactulose/not on lactulose (n = 33) were trained on the app. They entered self-reported BSS (self-BSS) with AI-BSS communicated. Lactulose dose changes were tracked. A subset (n = 12) was retested with AI communication blocked. Most subjects were comfortable with the app. Self/AI-BSS and lactulose dose/AI-BSS correlation increased with app use. AI-BSS communications improved insight into self-BSS over time. Dieta app to gauge stool AI characteristics was acceptable and increased insight into lactulose dose and BSS in cirrhosis.

Background: Hepatic encephalopathy (HE) caused by cirrhosis has severe consequences on an individual's lifespan, leading to long-term liver complications and potentially life-threatening outcomes. Despite recent interest in this condition, the effectiveness of secondary prophylaxis involving rixafimin, lactulose, or L-ornithine L-aspartate (LOLA) may be hindered by the unique microbial profiles each patient possesses. Methods: Thus, in this manuscript, we aimed to search, identify, and gather all randomized controlled trials (RCTs) published between 2000-2023 (November) in four major academic databases such as PubMed, ISI Web of Science, Scopus, and ScienceDirect by using a controlled terminology and web strings that reunite six main keywords. We complementarily retrieved data on the ongoing RCTs. Results: Regardless of the relatively high number of results displayed (n = 75), 46.66% (n = 35) were initially deemed eligible after the first evaluation phase after removing duplicates, n = 40 (53.34%). At the second assessment stage, we eliminated 11.42% (n = 4) studies, of which n = 22 finally met the eligibility criteria to be included in the main body of the manuscript. In terms of RCTs, otherwise found in distinct stages of development, n = 3 target FMT and n = 1 probiotics. Conclusions: Although we benefit from the necessary information and technology to design novel strategies for microbiota, only probiotics and synbiotics have been extensively studied in the last decade compared to FMT.

Context: Postoperative, critically ill, and elderly patients often have fecal loading or impaction. In a few such patients, disimpaction of fecalomas and colon cleansing are difficult. Bowel obstruction, megacolon, lower gastrointestinal bleeding, and gut perforation are complications that may ensue. Oral laxatives or enemas may only be partially effective. Surgical intervention may be needed for salvage or to treat complications. Series and Design: Fourteen hospitalized cases with defecation disorder due to fecal loading of the colon were enrolled for retrospective analysis. Colonoscopic instillation of mannitol and/or lactulose was undertaken as an intervention when the use of oral laxatives was either ineffective or unfeasible, and enema had yielded poor results. Results: Ten patients had satisfactory outcomes for fecal clearance, whereas four patients with poor or incomplete responses underwent repeat interventions or surgery. No significant complications were encountered due to this therapy. Conclusion: Colonoscopic instillation of mannitol or lactulose in fecal-loaded critically ill patients results in a safe and satisfactory fecal clearance. (AU)

Introduction and aim: Functional abdominal pain (FAP) is one of the major gastrointestinal complaints in childhood. Studies have reported occult constipation (OC) as one of the leading causes of abdominal pain. Recent researches have proposed laxatives as potent therapeutic targets for abdominal pain in patients with OC. However, no study has compared effect of poly ethylene glycol (PEG) and lactulose on occult constipation. Materials and methods: 51 patients aged 4 to 18 years with abdominal pain who had OC (defined as fecal impaction in abdominal X ray) were studied. Demographic and clinical data including age, sex, body weight, height, abdominal pain duration, abdominal pain rate and fecal odor were registered. They were randomly assigned to receive PEG (1gr/kg) or Lactulose (1cc/kg) for at least two weeks. All patients were reevaluated by pain measurement scale after at least two weeks of treatment. Results: It is indicated that the efficacy of PEG for reducing abdominal pain in OC was 48% while it was 37% for Lactulose. This study indicated that this efficacy is not affected significantly by sex and fecal odor, however this efficacy is influenced by age, body weight, abdominal pain duration and abdominal pain rate for both PEG and Lactulose. Conclusion: It could be concluded that PEG is a more efficient drug for treating abdominal pain in occult constipation than Lactulose and its optimum effect can be achieved in elder patients with more severe abdominal pain.
Introducción y objetivo: El dolor abdominal funcional (FAP) es una de las principales molestias gastrointestinales en la infancia. Los estudios han informado que el estreñimiento oculto (OC) es una de las principales causas de dolor abdominal. Investigaciones recientes han propuesto laxantes como objetivos terapéuticos potentes para el dolor abdominal en pacientes con OC. Sin embargo, ningún estudio ha comparado el efecto del polietilenglicol (PEG) y la lactulosa sobre el estreñimiento oculto. Materiales y métodos: Se estudiaron 51 pacientes de 4 a 18 años con dolor abdominal que tenían OC (definida como impactación fecal en rayos X abdominales). Se registraron datos demográficos y clínicos que incluyen edad, sexo, peso corporal, altura, duración del dolor abdominal, tasa de dolor abdominal y olor fecal. Fueron asignados aleatoriamente para recibir PEG (1 gr/kg) o lactulosa (1 cc/kg) durante al menos dos semanas. Todos los pacientes fueron reevaluados por la escala de medición del dolor después de al menos dos semanas de tratamiento. Resultados: Se indica que la eficacia de PEG para reducir el dolor abdominal en OC fue del 48% mientras que fue del 37% para la lactulosa. Este estudio indicó que esta eficacia no se ve afectada significativamente por el sexo y el olor fecal, sin embargo, esta eficacia está influenciada por la edad, el peso corporal, la duración del dolor abdominal y la tasa de dolor abdominal tanto para PEG como para lactulosa. Conclusión: Se podría concluir que el PEG es un fármaco más eficaz para tratar el dolor abdominal en el estreñimiento oculto que la lactulosa y que su efecto óptimo se puede lograr en pacientes mayores con dolor abdominal más severo.Palabras clave: dolor abdominal, estreñimiento oculto, polietilenglicol, lactulosa.

Objetivo: evaluar analítica y descriptivamente la evidencia publicada hasta la actualidad sobre el uso del polietilenglicol, solo o con electrolitos, en el tratamiento de pacientes con estreñimiento funcional. Metodología: búsqueda en las bases de datos MEDLINE, EMBASE y Cochrane hasta mayo de 2016 de todas las publicaciones que se ajustaran a los siguientes términos: constipation and/or fecal impaction and (PEG or polyethilene or macrogol or movicol or idralax or miralax or transipeg or forlax or golytely or isocolan or mulytely) not colonoscopy. Lectura crítica de los artículos seleccionados (únicamente en inglés o español) clasificando la descripción de los mismos en función de grupos de edad (adulto/ edad pediátrica) y, dentro de ellos, en función de las características de los estudios (evaluación de eficacia frente a placebo, búsqueda de dosis, seguridad, comparación con otros laxantes, estudios observacionales y artículos de revisión monográficos para poletilenglicol o metaanálisis). Resultados: se han seleccionado para análisis descriptivo 58 publicaciones; de ellas, 41 son ensayos clínicos, ocho son estudios observacionales y nueve son revisiones sistemáticas o metaanálisis. Doce ensayos clínicos evalúan la eficacia frente a placebo, ocho frente a lactulosa, seis estudio de dosis, cinco comparan entre sí el polietilenglicol con y sin electrolitos, dos comparan la eficacia con respecto a leche de magnesia y el resto de ensayos evalúan el polietilenglicol comparando con enemas (dos), ispágula (uno), tegaserod (uno), prucaloprida (uno), aceite de parafina (uno), combinaciones de fibras (uno) y Descurainia sophia (uno). Conclusiones: los preparados con polietilenglicol, únicos o asociados a electrolitos, son más eficaces que el placebo en el tratamiento del estreñimiento funcional tanto en adultos como en edad pediátrica con gran seguridad y tolerancia. Constituyen el laxante osmótico más eficaz (superior a la lactulosa) y de primera línea para el tratamiento de esta afección a corto y largo plazo. En la impactación fecal son tan eficaces como los enemas, evitan la necesidad de ingreso hospitalario y son muy bien tolerados por los pacientes (fundamentalmente, en su presentación sin electrolitos) (AU)
Objective: The objective of this study was to evaluate in an analytical and descriptive manner the evidence published so far on the use of polyethylene glycol (PEG), with or without electrolytes, in the management of functional constipation and the treatment of fecal impaction. Methodology: Search on MEDLINE, EMBASE and Cochrane databases until May 2016 of all publications adjusted to the following terms: constipation AND/OR fecal impaction AND (PEG OR polyethylene glycol OR macrogol OR movicol OR idralax OR miralax OR transipeg OR forlax OR golytely OR isocolan OR mulytely) NOT colonoscopy. Critical reading of selected articles (English or Spanish), sorting their description according to group age (adult/pediatric age) and within those, in accordance with study features (efficacy evaluation versus placebo, doses query, safety, comparison with other laxatives, observational studies and monographic review articles of polyethylene glycol or meta-analysis). Results: Fifty-eight publications have been chosen for descriptive analysis; of them, 41 are clinical trials, eight are observational studies and nine are systematic reviews or meta-analysis. Twelve clinical trials evaluate PEG efficacy versus placebo, eight versus lactulose, six are dose studies, five compare polyethylene glycol with and without electrolytes, two compare its efficacy with respect to milk of magnesia, and the rest of the trials evaluate polyethylene glycol with enemas (two), psyllium (one), tegaserod (one), prucalopride (one), paraffin oil (one), fiber combinations (one) and Descurainia sophia (one). Conclusions: Polyethylene glycol with or without electrolytes is more efficacious than placebo for the treatment of functional constipation, either in adults or in pediatric patients, with great safety and tolerability. These preparations constitute the most efficacious osmotic laxatives (more than lactulose) and are the first-line treatment for functional constipation in the short and long-term. They are as efficacious as enemas in fecal impaction, avoid the need for hospital admission and are well tolerated by patients (mainly when administered without electrolytes) (AU)
