Abstract
There is cumulative evidence that pancreatic exocrine insufficiency (PEI) is under-recognised and can occur in patients with 'at-risk' conditions. Thus, we aimed to assess the current practice and yield of requesting faecal elastase (FEL-1), an indicator of PEI, in patients with 'at-risk' conditions. We prospectively recruited patients attending secondary care clinics with diabetes mellitus (DM), people living with HIV (PLHIV) and inpatients admitted to hospital with high alcohol intake (HAI). All patients underwent testing with FEL-1. Those patients with PEI (FEL-1 <200 μg/g) were contacted and offered a follow-up review in gastroenterology clinic. In total, 188 patients were recruited (HAI, n=78; DM, n=64; and PLHIV, n=46). Previous FEL-1 testing had not been performed in any of the patients. The return rate of samples was 67.9% for patients with HAI, 76.6% for those with DM and 56.5% for those with PLHIV. The presence of PEI was shown in 20.4% of patients with DM, 15.4% of patients with PLHIV and 22.6% in those with HAI. Diarrhoea and bloating were the most reported symptoms in followed-up patients with low FEL-1 (31.8% and 22.7% of patients, respectively). Follow-up computed tomography (CT) scans in those patients with PEI identified chronic pancreatitis changes in 13.6% and pancreatic atrophy in 31.8% of patients. These results suggest that there is a lack of testing for PEI in 'at-risk' groups. Our findings also suggest that using FEL-1 to test for PEI in patients with DM, PLHIV and HAI has a significant impact, although further studies are required to validate these findings.

Alcohol consumption upon direct-acting antiviral therapy for hepatitis C among persons with human immunodeficiency virus in the United States. Drug Alcohol Depend 2022; 241:109673.

Abstract
BACKGROUND Direct-acting antivirals (DAA) are highly effective against hepatitis C virus (HCV) infection among persons with human immunodeficiency virus (PWH). However, alcohol use post-DAA treatment poses a continued threat to the liver. Whether the focus on liver health alone during HCV treatment can impact alcohol consumption is unclear. Therefore, we examined the change in alcohol use among HCV-coinfected PWH who received DAA therapy by non-addiction medical providers. METHODS In our longitudinal clinical cohort study, we identified HCV-coinfected PWH who received interferon-free DAA therapy between January 2014 and June 2019 in the Centers for AIDS Research Network of Integrated Clinical Systems. The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) was the alcohol screening instrument. We used mixed-effects logistic regression models to estimate the longitudinal change in alcohol use upon DAA therapy. RESULTS Among 738 HCV-coinfected PWH, 339 (46 %) reported any alcohol use at the end of HCV treatment, including 113 (15 %) with high-risk use (i.e., AUDIT-C ≥3 for women, ≥4 for men). Concurrently, 280 (38 %) PWH noted active drug use, and 357 (48 %) were currently smoking. We observed no changes in the odds of any alcohol or high-risk alcohol use over time with DAA therapy. Findings were similar in the PWH subgroup with a history of alcohol use before DAA treatment. CONCLUSIONS For PWH with HCV, alcohol use did not change following interferon-free DAA treatment by non-addiction medical providers. Thus, clinicians should consider integrating targeted alcohol use interventions into HCV care to motivate reduced alcohol consumption and safeguard future liver health.

Endoscopic Ultrasound Findings in Patients Diagnosed with Exocrine Pancreatic Insufficiency by Low Fecal Elastase-1. Gastroenterol Res Pract 2019; 2019:5290642. [PMID: 31485218 PMCID: PMC6710758 DOI: 10.1155/2019/5290642] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Revised: 05/09/2019] [Accepted: 07/02/2019] [Indexed: 12/17/2022] Open
Abstract
Background and Aims Fecal elastase-1 (FE-1) as a screening test for exocrine pancreatic insufficiency (EPI) is gaining popularity in clinical practice. The role of imaging in patients with FE-1-related suspicion of EPI remains unclear. The aim of this study was to characterize endoscopic ultrasound (EUS) findings for patients with low FE-1. Methods A retrospective cross-sectional study was performed in 40 patients who had low FE-1 and underwent EUS to evaluate the pancreas. We obtained data on demographic and lifestyle factors, EUS findings, and histopathology results. We compared these variables between patients with FE-1 < 100 mcg/g vs. 100-200 mcg/g. Results Most patients (82.5%) established one or more new diagnoses from EUS. Diagnoses included: definitive chronic pancreatitis (n = 29, 72.5%), fatty pancreas (n = 9, 22.5%), and pancreatic solid mass or cyst (n = 9, 22.5%). Half (n = 4) of the solid or cystic lesions were neoplastic. All patients with a solid pancreatic mass also had concurrent chronic pancreatitis. There were no significant differences in EUS findings or demographic or lifestyle factors between groups with FE-1 < 100 mcg/g vs. 100-200 mcg/g. Conclusion Chronic pancreatitis is the most common EUS finding in patients with low FE-1 levels. EUS appears helpful in determining the cause of EPI in most patients with low FE-1 and may detect unsuspected pancreatic neoplasia.

Abstract
AIMS In exocrine pancreatic insufficiency (EPI), the quantity and/or activity of pancreatic digestive enzymes are below the levels required for normal digestion, leading to maldigestion and malabsorption. Diagnosis of EPI is often challenging because the characteristic signs and symptoms overlap with those of other gastrointestinal conditions. Additionally, there is no single convenient, or specific diagnostic test for EPI. The aim of this review is to provide a framework for differential diagnosis of EPI vs other malabsorptive conditions. METHODS This is a non-systematic narrative review summarising information pertaining to the aetiology, diagnosis and management of EPI. RESULTS Exocrine pancreatic insufficiency may be caused by pancreatic disorders, including chronic pancreatitis, cystic fibrosis, pancreatic resection and pancreatic cancer. EPI may also result from extra-pancreatic conditions, including coeliac disease, Zollinger-Ellison syndrome and gastric surgery. Timely and accurate diagnosis of EPI is important, as delays in treatment prolong maldigestion and malabsorption, with potentially serious consequences for malnutrition, overall health and quality of life. Symptoms of EPI are non-specific; therefore, a high index of clinical suspicion is required to make a correct diagnosis.

Abstract
BACKGROUND Pancreatic exocrine insufficiency (PEI) results in maldigestion due to inadequate activity of pancreatic enzymes in the small bowel. PEI can arise from a variety of medical conditions that reduce enzyme synthesis within the pancreatic parenchyma or from secondary factors that may occur despite optimal parenchymal function, such as pancreatic duct obstruction or impaired or poorly synchronized enzyme release. PURPOSE To provide practical guidance for primary care physicians managing patients who are at risk of PEI or who present with symptoms of PEI. METHODS For each of six key clinical questions identified by the authors, PubMed searches were conducted to identify key English-language papers up to April 2017. Forward and backward searches on key articles were conducted using Web of Science. Clinical recommendations proposed by the co-chairs (P.D. and C.T.) were vetted and approved based on the authors? FINDINGS The most characteristic symptom of PEI is steatorrhea ? voluminous, lipid-rich stools; other common signs and symptoms include unexplained weight loss and deficiencies of fat-soluble vitamins and other micronutrients. Pancreatic enzyme replacement therapy (PERT) can relieve symptoms and long-term sequelae of PEI. Diagnosis of PEI and initiation of PERT are usually the responsibility of gastroenterology specialists. However, primary care physicians (PCPs) are well positioned to identify potential cases of PEI and to participate in the collaborative, long-term management of patients already seen by a specialist. CONCLUSIONS In this document, a panel of Canadian gastroenterologists has conducted a critical review of the literature on PEI and PERT and has developed practical diagnostic and treatment recommendations for PCPs. These recommendations provide guidance on identifying patients at risk of PEI, the triggers for PEI testing and referral, and best practices for co-managing patients with confirmed PEI.

Abstract
PURPOSE OF REVIEW The review examines the changing causes and the investigation of infectious and noninfectious diarrhoea in individuals with HIV. RECENT FINDINGS Despite the excellent prognosis conferred by combination antiretroviral therapy, diarrhoea is still common in HIV-positive individuals and is associated with reduced quality of life and survival. There is increasing interest in the importance of Th17 and Th22 T cells in the maintenance of mucosal immunity within the gut, and in the role of the gut microbiome in gut homeostasis. Bacterial causes of HIV-associated diarrhoea continue to be important in resource-poor settings. In other settings, sexually transmitted enteric infections such as lymphogranuloma venereum and shigellosis are increasingly reported in men who have sex with men. HIV increases the risk of such infections and the presence of antimicrobial resistance. Parasitic causes of diarrhoea are more common in individuals with uncontrolled HIV and low CD4 counts. Noninfectious causes of diarrhoea include all classes of antiretroviral therapy, which is under-recognised as a cause of poor treatment adherence. Pancreatic dysfunction is remediable and the diagnostic workup of HIV-related diarrhoea should include faecal elastase measurements. New antimotility agents such as crofelemer may be useful in managing secretory diarrhoea symptoms. SUMMARY Clinicians looking after patients with HIV should ask about diarrhoeal symptoms, which are under-reported and may have a remediable infectious or noninfectious cause.

Abstract
OBJECTIVES The primary aim of this prospective study was to determine the prevalence of exocrine pancreatic insufficiency (EPI) in people living with HIV (PLHIV) on suppressive antiretroviral therapy (ART). METHODS PLHIV ≥18 years of age and on ART for >6 months and with HIV RNA <50 copies/mL plasma were included. Faecal elastase-1 measurement was performed on a single stool sample, serum markers of malnutrition were collected, and participants answered a short questionnaire about gastrointestinal symptoms. Participants with EPI and symptoms were offered pancreatic enzyme replacement therapy (PERT), and the result of this therapy was also evaluated. RESULTS Of 100 participants, 32% had EPI (faecal elastase-1 < 200 μg/g) and 20% severe EPI (faecal elastase-1 < 100 μg/g). We did not find any correlation between self-reported symptoms and degree of EPI. Twelve out of the 32 participants with EPI accepted to start PERT. Nine out of 12 (75%) reported improvement or became asymptomatic within 14 days. CONCLUSION EPI is common in PLHIV on effective ART. We could, however, not find a correlation between gastrointestinal symptoms and the presence of EPI. Assessment of pancreatic exocrine function could be considered in PLHIV particularly in those with gastrointestinal discomfort, since there is a possible gain in treating them with relief of symptoms and improved quality of life. The effects of PERT in PLHIV on effective ART need further study.

Abstract
The early diagnosis of pancreatic exocrine insufficiency (PEI) is hindered because many of the functional diagnostic techniques used are expensive and require specialized facilities, which prevent their widespread availability. We have reviewed current evidence in order to compare the utility of these functional diagnostic techniques with the fecal elastase-1 (FE-1) test in the following three scenarios: screening for PEI in patients presenting with symptoms suggestive of pancreatic disease, such as abdominal pain or diarrhea; determining the presence of PEI in patients with an established diagnosis of pancreatic disease, such as chronic pancreatitis or cystic fibrosis; determining exocrine status in disorders not commonly tested for PEI, but which have a known association with this disorder. Evidence suggests the FE-1 test is reliable for the evaluation of pancreatic function in many pancreatic and non-pancreatic disorders. It is non-invasive, is less time-consuming, and is unaffected by pancreatic enzyme replacement therapy. Although it cannot be considered the gold-standard method for the functional diagnosis of PEI, the advantages of the FE-1 test make it a very appropriate test for screening patients who may be at risk of this disorder.

Abstract
PRIMARY STUDY OBJECTIVE Determine the frequency of abnormal fecal biomarker test results in patients with 13 irritable bowel syndrome (IBS)-related ICD-9 (International Statistical Classification of Diseases and Related Health Problems) codes. STUDY DESIGN Quantitative review of de-identified records from patients in whom IBS was a possible diagnosis. METHODS Records were selected for analysis if they included any of 13 IBS-related diagnostic codes and laboratory test results of fecal testing for all biomarkers of interest. Data collection was restricted to one 12-month period. Frequency distributions were calculated to identify rates of abnormal results for each biomarker within the total number of tests conducted in the eligible population. RESULTS Two thousand, two hundred fifty-six records were included in the study, of which 1867 (82.8%) included at least one abnormal value. Quantitative stool culture for beneficial bacteria (Lactobacillus and Bifidobacterium) indicated low growth suggestive of intestinal dysbiosis in 73.1% of records, followed by abnormally elevated eosinophil protein X (suggestive of food allergy) in 14.3%, elevated calprotectin (suggestive of inflammation) in 12.1%, detection of parasites in 7.5%, and low pancreatic elastase (suggestive of exocrine pancreatic insufficiency) in 7.1%. CONCLUSIONS Abnormal fecal biomarkers are prevalent in patients with diagnoses suggestive of IBS. Abnormal fecal biomarker testing, if confirmed in additional independent clinical trials, could substantially reduce the economic costs associated with diagnosis and management of IBS.
