RESUMEN
INTRODUCTION: Bile acid diarrhea is a common cause of bowel symptoms and often goes unrecognized or misdiagnosed. Many aspects of management remain contentious. AREAS COVERED: The primary, idiopathic condition should be suspected in people with functional diarrhea or diarrhea-predominant irritable bowel syndrome. Secondary causes include ileal resection, inflammation, and post-cholecystectomy. Diagnostic tests vary globally, being unavailable in many countries, and further refinement of testing strategy is needed. Management is usually long-term symptom control, rather than reversal of the causative factors, which are still being defined. Bile acid sequestrants remain the main drugs used. They are relatively inexpensive, and better-quality data is now available for colesevelam. However, optimal use, including timing and formulation, needs clarification. The GLP-1 receptor agonist, liraglutide, is also effective, although mechanisms of action and whether this effect is common to other class members is unclear. They are more expensive, and availability varies. FXR agonists can also be effective but require further validation. The role of dietary factors in symptom development is a major patient concern, needing more formal studies. EXPERT OPINION: To build on recent findings, bile acid diarrhea needs further investment into causes, diagnosis and therapy to guide present and future patient care.
The condition known as bile acid diarrhea (BAD) causes frequent loose stools, which need to be passed urgently, sometimes causing incontinence. It can be a complication of surgery or other intestinal disorders, and gives similar symptoms to IBS. It is not widely known and clinicians often fail to diagnose it. In this article, we review recent publications about how to make the diagnosis of BAD. Some of these are contentious and there may be limited availability of the tests or poor accuracy. We then review current treatments and how to best manage BAD. There are some new treatments, which are not yet fully proven or accepted for general use. We review these and express opinions regarding the current best practices in diagnosis and treatment, and how these may change in the next 5 years.
RESUMEN
This case highlights the potential role of SARS-CoV-2 in triggering lymphocytic colitis, emphasizing the need for further research and vigilance in identifying potential post-COVID-19 GI complications. We describe a case of a young adult who experienced chronic diarrhea and abdominal pain for 10 months after a SARS-CoV-2 infection. Extensive laboratory and imaging investigations yielded no significant findings. Despite a preliminary diagnosis of irritable bowel syndrome and symptomatic treatment, symptoms persisted. Colonoscopy with biopsies revealed unremarkable colonic mucosa but confirmed moderate lymphocytic infiltration consistent with lymphocytic colitis. Treatment with budesonide achieved complete symptom resolution. The findings underscore the importance for clinicians to consider triggered microscopic colitis in patients presenting with persistent diarrhea following SARS-CoV-2 infection.
RESUMEN
BACKGROUND: Chronic non-bloody diarrhea may be attributed either to functional or organic diseases. The latter category may present with malabsorption syndrome if there is extensive involvement of the small bowel, whereas diseases of the large bowel may only present with diarrhea sans malabsorption. Indian data has predominantly focussed on the etiological spectrum of malabsorption syndrome in adults. The primary aim of the current study was to evaluate etiological spectrum of chronic organic non-bloody diarrhea in India. METHODS: This prospective observational study was done at a tertiary care hospital in North India. Patients ≥ 18 years presenting with chronic non-bloody diarrhea of > 4 weeks duration were enrolled in the study after exclusion of patients with IBS and anal incontinence. RESULTS: During the study period of 12 months, 100 patients with chronic organic non-bloody diarrhea were evaluated. A definite etiological diagnosis was made in 97 patients (97%). The mean age of the patients was 48 ± 16.7 years (58% males). The median duration of diarrhea was 5.5 months (interquartile range [IQR] 3.5, 11). Inflammatory bowel disease (IBD) accounted for 45% of the cases making it the predominant cause for organic diarrhea. GI infections and adult-onset celiac disease accounted for 18% and 9% of the cases, respectively. Pancreatic disease, benign or neoplastic, accounted for 6% of the total cases. Notably, gastrointestinal (GI) malignancies manifesting as chronic non-bloody diarrhea were diagnosed in 5% of the patients. CONCLUSION: Our data suggests a paradigm shift in the etiological spectrum of chronic organic non-bloody diarrhea in India with the emergence of IBD as the predominant cause displacing GI infections.
RESUMEN
Chronic diarrhea has a considerable impact on quality of life. This randomized, double-blind, placebo-controlled crossover intervention trial was conducted with 69 participants (36 in Group A, 33 in Group B), aiming to investigate the potential of postbiotics in alleviating diarrhea-associated symptoms. Participants received postbiotic Probio-Eco® and placebo for 21 days each in alternating order, with a 14-day washout period between interventions. The results showed that postbiotic intake resulted in significant improvements in Bristol stool scale score, defecation frequency, urgency, and anxiety. Moreover, the postbiotic intervention increased beneficial intestinal bacteria, including Dysosmobacter welbionis and Faecalibacterium prausnitzii, while reducing potential pathogens like Megamonas funiformis. The levels of gut Microviridae notably increased. Non-targeted metabolomics analysis revealed postbiotic-driven enrichment of beneficial metabolites, including α-linolenic acid and p-methoxycinnamic acid, and reduction of diarrhea-associated metabolites, including theophylline, piperine, capsaicin, and phenylalanine. Targeted metabolomics confirmed a significant increase in fecal butyric acid after postbiotic intervention. The levels of aromatic amino acids, phenylalanine and tryptophan, and their related metabolites, 5-hydroxytryptophan and kynurenine, decreased after the postbiotic intervention, suggesting diarrhea alleviation was through modulating the tryptophan-5-hydroxytryptamine and tryptophan-kynurenine pathways. Additionally, chenodeoxycholic acid, a diarrhea-linked primary bile acid, decreased substantially. In conclusion, postbiotics have shown promise in relieving chronic diarrhea.

BACKGROUND: Diarrhea is commonly associated with irritable bowel syndrome, inflammatory bowel disease, microscopic colitis, and other gastrointestinal dysfunctions. Spontaneously occurring idiopathic chronic diarrhea is frequent in rhesus macaques, but has not been used as a model for the investigation of diarrhea or its treatment. We characterized this condition and present preliminary data demonstrating that left vagal nerve stimulation provides relief. METHODS: Stool consistency scores were followed for up to 12 years. Inflammation was assessed by plasma C-reactive protein, [18F]fluorodeoxyglucose (FDG) uptake, measured by positron emission tomography (PET), multiplex T cell localization, endoscopy and histology. The vagus was stimulated for 9 weeks in conscious macaques, using fully implanted electrodes, under wireless control. KEY RESULTS: Macaques exhibited recurrent periods of diarrhea for up to 12 years, and signs of inflammation: elevated plasma C-reactive protein, increased bowel FDG uptake and increased mucosal T helper1 T-cells. The colon and distal ileum were endoscopically normal, and histology revealed mild colonic inflammation. Application of vagal nerve stimulation to conscious macaques (10 Hz, 30 s every 3 h; 24 h a day for 9 weeks) significantly reduced severity of diarrhea and also reduced inflammation, as measured by FDG uptake and C-reactive protein. CONCLUSIONS AND INFERENCES: These macaques exhibit spontaneously occurring diarrhea with intestinal inflammation that can be reduced by VNS. The data demonstrate the utility of this naturally occurring primate model to study the physiology and treatments for chronic diarrhea and the neural control circuits influencing diarrhea and inflammation that are not accessible in human subjects.

BACKGROUND: Dietary fiber is essential for human health and can help reduce the symptoms of constipation. However, the relationship between dietary fiber and diarrhea is, poorly understood. AIM: To evaluate the relationship between dietary fiber and chronic diarrhea. METHODS: This retrospective study was conducted using data from the United States National Health and Nutrition Examination Survey, conducted between 2005 and 2010. Participants over the age of 20 were included. To measure dietary fiber consumption, two 24-hour meal recall interviews were conducted. The independent relationship between the total amount of dietary fiber and chronic diarrhea was evaluated with multiple logistic regression and interaction analysis. RESULTS: Data from 12829 participants were analyzed. Participants without chronic diarrhea consumed more dietary fiber than participants with chronic diarrhea (29.7 vs 28.5, P = 0.004). Additionally, in participants with chronic diarrhea, a correlation between sex and dietary fiber intake was present: Women who consume more than 25 g of dietary fiber daily can reduce the occurrence of chronic diarrhea. CONCLUSION: Dietary fiber can reduce the occurrence of chronic diarrhea.
RESUMEN
INTRODUCTION: Celiac disease (CD) is a chronic inflammatory disorder affecting mainly the digestive system and accounts for more than 50% of adult cases presenting to the gastrointestinal clinic with chronic diarrhea. Therefore, in our study, we aimed to determine the prevalence of CD in patients presenting with chronic diarrhea at the gastroenterology outpatient department of Jinnah Hospital, Lahore. METHODS: This cross-sectional study was conducted from December 9, 2021, to June 8, 2022, and included 140 patients aged 18 to 50 years with chronic diarrhea. Exclusion criteria were lack of informed consent and history of abdominal trauma or surgery. Data collected included age, gender, family history of CD, and clinical symptoms. Diagnostic measures involved serum tissue transglutaminase antibody IgA and IgG levels, endoscopy, and duodenal biopsy. Statistical analysis was performed using SPSS version 23 (IBM Corp, Armonk, NY), with a p-value of ≤0.05 considered significant. RESULTS: Among the 140 patients, 80 (57.14%) were males, with a mean age of 21 ± 4.35 years. Common symptoms included weight loss (73.5%), abdominal pain (20.7%), and stunted growth (5.7%). A family history of CD was reported in 14.29% of patients. Endoscopy findings included fissuring of the duodenal mucosa (77.9%), decreased height of duodenal folds (15.7%), and nodularity (6.4%). Histopathological examination revealed Marsh III b (65%), Marsh III c (21.4%), and Marsh III a (9.3%). CD was diagnosed in 23.57% of patients. Significant associations were found between CD and female gender, family history of CD, weight loss, stunted growth, and Marsh III c histopathology. CONCLUSION: CD was diagnosed in 23.57% of patients with chronic diarrhea. It was more prevalent in females and those with a family history of CD. These findings emphasize the need for considering CD in the differential diagnosis of chronic diarrhea to ensure early detection and management.
RESUMEN
BACKGROUND: Huangtu decoction (HTD), a traditional Chinese medicine recipe, warms the spleen, nourishes the blood, and stops bleeding. It has been used to treat dysentery, gastrointestinal bleeding, diarrhea, and other symptoms caused by spleen-yang deficiency for more than 2,000 years in China. However, the mechanism underlying the treatment of chronic diarrhea due to spleen-yang deficiency (CDSD) using HTD remains unclear. AIMS: This study investigated whether HTD could mediate intestinal flora and serum metabolites to improve CDSD symptoms using a mouse model. METHODS: A CDSD mouse model induced by senna and an abnormal diet was constructed. The regulatory effects of HTD at 12.5, 25.0, and 50.0 g/kg/d on CDSD mice were assessed by measuring their bodyweight, diarrhea rate, loose stool rate, and histopathology. Changes in the intestinal flora of CDSD mice were analyzed by 16S rRNA gene sequencing. Untargeted serum metabolomic analysis was performed using ultra-high performance liquid chromatography-mass spectrometry/mass spectrometry (UHPLC-MS/MS). RESULTS: HTD had a modulating effect on CDSD by reducing the weight loss, diarrhea rate, loose stool rate, and pathologic damage. Intestinal flora analysis showed that HTD altered the community composition by decreasing the abundance of Allobaculum, Lactobacillus, and Ruminococcus. Serum metabolomics revealed that ascorbate and aldarate metabolism, aldosterone synthesis and secretion, platelet activation, hypoxia-inducible factor 1 signaling pathway, inositol phosphate metabolism, phosphatidylinositol signaling, galactose metabolism, and alpha-linolenic acid metabolism were modulated after HTD treatment. CONCLUSION: HTD may alleviate CDSD symptoms by reducing weight loss, diarrhea rate, loose stool rate, and pathologic damage caused by modeling and regulating intestinal flora and serum metabolites in CDSD mice.
RESUMEN
Introduction: Celiac disease (CD) is a systemic autoimmune enteropathy triggered by dietary gluten in genetically susceptible individuals. Celiac disease affects 0.6-1.0% of the population worldwide. The prevalence of CD in Pakistan is yet unknown due to under diagnosis and lack of awareness. Objective: To determine a vast variety of presenting features in subtypes of CD to overcome the burden of disease. Materials and methods: This was a prospective, comparative, cross-sectional study conducted at Gastroenterology department of Jinnah Postgraduate Medical Center, Karachi from December 2022 till June 2023. This study included all adult patients ≥18 years diagnosed with CD on the basis of clinical presentation, positive IgA and IgG anti-transglutaminase antibodies (value >12 IU/mL detected by ELISA followed by small intestinal biopsy classified as per Marsh criteria. The data obtained were analyzed on the statistical software SPSS version 23. Descriptive statistics were obtained by frequencies and percentages. Results: About 142 patients were enrolled in the study, 103 (91.5%) had classical CD (CCD) whereas 36 (25%) had non-classical (NCCD). About 89 (62.7%) were females and 53 (37.3%) were males. The mean age was found to be 23 ± 6 years. Nutritional deficiencies including anemia, B12, folate, osteopenia and low body mass index (BMI) <18 was found more in CCD group as compared with NCCD group with significant p-values. Titers of anti-TTG between CCD and NCCD were not statistically significant. Hypothyroidism and PCOS were the most common associated conditions observed in adult CD patients. Conclusion: In conclusion, CD in adults and has diverse presentations. Adults with unexplained extra-intestinal symptoms like anemia and bone pain should be investigated for CD.

RESUMEN
OBJECTIVES: We aimed to evaluate the clinical response to cholestyramine in patients with functional chronic diarrhea and a high clinical suspicion of bile-acid diarrhea (BAD) investigated with 75-selenium homocholic acid taurine (SeHCAT) test. METHODS: Adult patients attending our outpatient clinic between January and December 2021 for chronic diarrhea with suspicion of BAD were proposed SeHCAT testing and a therapeutic trial of cholestyramine 4-8 g daily. Clinical response to cholestyramine was evaluated at 1, 3, 6, and 12 months. Clinical and demographic data were analyzed according to SeHCAT test results. RESULTS: Among the 50 patients with chronic diarrhea and clinical suspicion of BAD, 13 (26.0%) refused either SeHCAT testing or cholestyramine therapy. Finally, 37 patients (31 females, age 44 ± 14 years) agreed to undergo SeHCAT and were started on cholestyramine (median follow-up 14 months [interquartile range 6-16 months]). Initial response to cholestyramine was similar in patients with positive and negative SeHCAT test results, but improved over time in those with a positive test result. Long-term response (100% vs 65.2%, P = 0.02) and necessity of maintenance therapy for symptom control were more common in those with positive SeHCAT test result (71.4% vs 26.1%, P = 0.02). However, response to cholestyramine was also frequent in patients with a negative test result. CONCLUSIONS: The SeHCAT test accurately identifies patients with BAD who benefit from long-term cholestyramine treatment. Nevertheless, cholestyramine may be also effective in patients with chronic diarrhea but negative SeHCAT test result.

OBJECTIVE: Chronic diarrhea affects approximately 5% of the population. Opioids inhibit gastrointestinal motility, and opium tincture has shown anti-propulsive effects in healthy, but no controlled studies of its clinical efficacy exist. We aimed to investigate the anti-propulsive and central nervous system (CNS) effects of opium tincture in patients with chronic diarrhea. MATERIALS AND METHODS: The study was a randomized, double-blinded, placebo-controlled, cross-over trial in subjects with chronic diarrhea refractory to standard treatment. Participants received opium tincture or placebo during two intervention periods, each lasting seven days. Bowel movements were recorded daily, and gastrointestinal transit time was investigated with the wireless motility capsule system. Gastrointestinal symptoms, health-related quality of life, and CNS effects (pupil size, reaction time, memory, and general cognition) were also investigated, along with signs of addiction. RESULTS: Eleven subjects (mean age: 45 ± 17 years, 46% males) with a median of 4.7 daily bowel movements were included. The number of daily bowel movements was reduced during opium tincture treatment to 2.3 (p = 0.045), but not placebo (3.0, p = 0.09). Opium tincture prolonged the colonic transit time compared to placebo (17 h vs. 12 h, p < 0.001). In both treatment arms, there were no changes in self-reported gastrointestinal symptoms, health-related quality of life, or CNS effects, and no indication of addiction was present. CONCLUSION: Opium tincture induced anti-propulsive effects in patients with chronic diarrhea refractory to standard treatment. This indicates that opium tincture is a relevant treatment strategy for selected patients with chronic diarrhea. Moreover, no evidence of opioid-induced sedation or addiction was found.Trial Registration Number: NCT05690321 (registered 2023-01-10).

BACKGROUND: Obesity is associated with a significantly increased risk for chronic diarrhea, which has been proposed as Linghu's obesity-diarrhea syndrome (ODS); however, its molecular mechanisms are largely unknown. AIM: To reveal the transcriptomic changes in the jejunum involved in ODS. METHODS: In a cohort of 6 ODS patients (JOD group), 6 obese people without diarrhea (JO group), and 6 healthy controls (JC group), high-throughput sequencing and bioinformatics analyses were performed to identify jejunal mucosal mRNA expression alterations and dysfunctional biological processes. In another cohort of 16 ODS patients (SOD group), 16 obese people without diarrhea (SO group), and 16 healthy controls (SC group), serum diamine oxidase (DAO) and D-lactate (D-LA) concentrations were detected to assess changes in intestinal barrier function. RESULTS: The gene expression profiles of jejunal mucosa in the JO and JC groups were similar, with only 1 differentially expressed gene (DEG). The gene expression profile of the JOD group was significantly changed, with 411 DEGs compared with the JO group and 211 DEGs compared with the JC group, 129 of which overlapped. The enrichment analysis of these DEGs showed that the biological processes such as digestion, absorption, and transport of nutrients (especially lipids) tended to be up-regulated in the JOD group, while the biological processes such as rRNA processing, mitochondrial translation, antimicrobial humoral response, DNA replication, and DNA repair tended to be down-regulated in the JOD group. Eight DEGs (CDT1, NHP2, EXOSC5, EPN3, NME1, REG3A, PLA2G2A, and PRSS2) may play a key regulatory role in the pathological process of ODS, and their expression levels were significantly decreased in ODS patients (P < 0.001). In the second cohort, compared with healthy controls, the levels of serum intestinal barrier function markers (DAO and D-LA) were significantly increased in all obese individuals (P < 0.01), but were higher in the SOD group than in the SO group (P < 0.001). CONCLUSION: Compared with healthy controls and obese individuals without diarrhea, patients with Linghu's ODS had extensive transcriptomic changes in the jejunal mucosa, likely affecting intestinal barrier function and thus contributing to the obesity and chronic diarrhea phenotypes.

BACKGROUND: Probiotics are living microorganisms that may confer health benefits to their host if administered in sufficient quantities. However, data on the use of probiotics in transplant recipients are scarce. METHOD: This multi-center survey of pediatric nephrologists aimed to examine variations in practice regarding the use of probiotics in pediatric kidney transplant recipients. The survey was conducted via a 10-item questionnaire (developed in Survey Monkey) administered to pediatric nephrologists participating in the Pediatric Nephrology Research Consortium meeting in April 2023. RESULTS: Sixty-four pediatric nephrologists completed the survey. Twenty-seven (42.2%) respondents reported having prescribed probiotics to pediatric kidney transplant recipients. The primary reason for probiotic use was the treatment of antibiotic-associated diarrhea (n = 20), with other reasons including recurrent Clostridium difficile infection (n = 15), general gut health promotion (n = 12), recurrent urinary tract infections (n = 8), and parental request (n = 1). Of those who prescribed probiotics, 48.1% held them during periods of neutropenia and 14.8% during central venous line use. Of the 64 respondents, 20 reported the lack of safety data as a concern for using probiotics in kidney transplant recipients. CONCLUSION: Pediatric nephrologists are increasingly prescribing probiotics to pediatric kidney transplant recipients; nevertheless, substantial practice variations exist. The paucity of safety data is a significant deterrent to probiotic use in this population.

Microscopic colitis (MC) is characterized by chronic watery diarrhea that requires histological examination for diagnosis. Here, we present a case of a 63-year-old female with rheumatoid arthritis who developed persistent diarrhea following leflunomide initiation. Despite a normal colonoscopy, random colonic biopsies confirmed MC. Discontinuation of leflunomide led to symptom resolution, implicating it as the causative agent. Leflunomide-induced MC is exceedingly rare, with limited documented cases. Understanding its variability in presentation and timely recognition is crucial. This case underscores the importance of thorough medication history assessment and consideration of drug-induced colitis in patients presenting with unexplained diarrhea, facilitating prompt management and resolution.
RESUMEN
Key Clinical Message: Good's syndrome (GS) presents with thymoma, hypogammaglobulinemia, and recurrent infection. The manifestations of patients diagnosed with GS and Cytomegalovirus (CMV) gastroenteritis are rare and non-specific. Early diagnosis and treatment can improve the prognosis of the rare disease. Abstract: Good's syndrome (GS), a rare acquired immunodeficiency condition, is characterized by thymoma, hypogammaglobulinemia, and low peripheral B-lymphocyte count. GS tends to occur in individuals aged 40-60 years, resulting in increased risk of recurrent infections with various conditional pathogenic bacteria, viruses, and fungi. Cytomegalovirus (CMV) can cause pneumonia, retinitis, encephalitis, and enteritis in GS patient, but CMV infection in the alimentary tract is usually underestimated, delayed diagnosed and misdiagnosed. In this study, we reported a female patient with GS and chronic diarrhea due to CMV infection and reviewed the literature to conclude the characteristics of this rare condition to improve the clinical diagnosis and prognosis of CMV gastroenteritis in patients with GS.

Chronic constipation, diarrhea, and fecal incontinence have high incidence, potential disability, and socioeconomic impact, imposing a heavy burden on the quality of life. We aim to explore the association between cardiovascular health (CVH) and bowel health from National Health and Nutrition Survey 2005-2010. CVH is assessed using Life's Essential 8 (LE8). Chronic constipation, chronic diarrhea, and fecal incontinence are assessed based on Bristol Stool Form Scale classification, bowel movements, and bowel leakage. Better health behaviors (odds ratio [OR]: 0.71, 95% confidence interval [CI] 0.53-0.94, p = 0.02) and worse health factors (OR: 1.45, CI 1.03-2.04, p = 0.04) were associated with less chronic constipation. Less chronic diarrhea is correlated with better CVH (OR: 0.53, 95% CI 0.35-0.79, p = 0.003) and health factors (OR: 0.61, CI 0.46-0.81, p = 0.001). Meanwhile, the proportion of chronic diarrhea significantly decreases when the health behaviors score exceeds 59.42. Lower fecal incontinence was associated with better health behaviors (OR: 0.63, CI 0.44-0.90, p = 0.01) CVH. Better CVH and health behaviors are both linked to lower all-cause mortality in participants with chronic constipation and chronic diarrhea. A higher health behaviors score is also associated with less all-cause mortality in patients with fecal incontinence. Maintaining CVH at the population level contributes to intestinal health, achieving the dual management of both while saving on healthcare costs. However, further prospective research is needed to confirm these associations.

Background: Circadian rhythms are reported to influence physiological processes in the gastrointestinal system, but associations between circadian syndrome (Circs) and chronic diarrhea (CD) remain unclear. Here, we explored such relationships to provide new insights into CD management. Methods: We conducted a cross-sectional retrospective analysis using the National Health and Nutrition Examination Survey (NHANES) data between 2005 and 2010. Univariate and multivariable logistic regression analyses were performed on weighted data to explore associations between Circs and CD. Results: Results were presented using forest plots, odds ratios (ORs), and 95% confidence intervals (CIs). Data with p-values < 0.05 were considered statistically significant. In total, 5,661 US participants, of which 412 had CD (weighted percentage = 6.20%), were enrolled. In univariate logistic regression analyses, participants with Circs had a significantly higher risk of CD (OR = 1.51, 95% CI: 1.15-1.99). After adjusting for covariates, model 2 (OR = 1.40, 95% CI: 1.03-1.90) and model 3 (OR = 1.42, 95% CI: 1.01-2.00) data were consistent with model 1 data. Additionally, the number of Circs components was positively associated with CD in all three models. Subgroup analyses revealed an association between CD and Circs in participants who had high blood pressure (OR = 2.46, 95% CI: 1.48-4.11, p < 0.001). Conclusion: In this cross-sectional study, we found that Circs is positively associated with the risk of CD in US adults, especially in those with high blood pressure. This association may provide new management strategies for CD.
RESUMEN
INTRODUCTION: Fucokinase deficiency-related congenital disorder of glycosylation (FCSK-CDG) is a rare autosomal recessive inborn error of metabolism characterized by a decreased flux through the salvage pathway of GDP-fucose biosynthesis due to a block in the recycling of L-fucose that exits the lysosome. FCSK-CDG has been described in 5 individuals to date in the medical literature, with a phenotype comprising global developmental delays/intellectual disability, hypotonia, abnormal myelination, posterior ocular disease, growth and feeding failure, immune deficiency, and chronic diarrhea, without clear therapeutic recommendations. PATIENT AND METHODS: In a so far unreported FCSK-CDG patient, we studied proteomics and glycoproteomics in vitro in patient-derived fibroblasts and also performed in vivo glycomics, before and after treatment with either D-Mannose or L-Fucose. RESULTS: We observed a marked increase in fucosylation after D-mannose supplementation in fibroblasts compared to treatment with L-Fucose. The patient was then treated with D-mannose at 850 mg/kg/d, with resolution of the chronic diarrhea, resolution of oral aversion, improved weight gain, and observed developmental gains. Serum N-glycan profiles showed an improvement in the abundance of fucosylated glycans after treatment. No treatment-attributed adverse effects were observed. CONCLUSION: D-mannose is a promising new treatment for FCSK-CDG.

Infectious causes of diarrhea contribute significantly to morbidity in Asia. We conducted a systematic review and meta-analysis of the prevalence of infectious etiologies of persistent and chronic diarrhea in Asian adults. Searches were performed on PubMed and Scopus for studies from January 1, 1970, to May 30, 2023. Sixteen studies were identified and included. The meta-analysis was conducted with the random-effects method, estimating the pooled prevalence of groups of infectious pathogens as causes of persistent and chronic diarrhea among Asian adults. The findings were highly heterogeneous and indicative of publication bias. The majority of studies were conducted on persons living with human immunodeficiency virus infection (PLHIV). The studies were predominantly from low-income and middle-income Asian countries. The most common cause was parasitic, with a pooled prevalence of 0.52 (95% confidence interval 0.28-0.65, I2 = 99%, Cochran's Q = 1027.44, P < 0.01), followed by bacterial, fungal, and viral causes, which were substantially rarer. Negative microbiological testing was also common, with a pooled prevalence for a negative test being 0.37 (95% confidence interval 0.17-0.52, I2 = 99%, Cochran's Q = 1027.44, P < 0.01). Subgroup analyses of studies conducted among PLHIV, from year 2000 and among those conducted in Southeast Asia showed a similar prevalence of parasitic causes of diarrhea. In conclusion, in Asian adults with persistent and chronic diarrhea, parasitic causes were most prevalent. However, the estimate of true prevalence is limited by significant heterogeneity among the available studies. More study in this field is required, especially examining PLHIV in the post-antiretroviral therapy era and from high-income countries.
