Outpatient screening with the Royal Free Hospital-Nutrition Prioritizing Tool for patients with cirrhosis at risk of malnutrition.

OBJECTIVES: Malnutrition is common among inpatients with cirrhosis. However, data on the prevalence of malnutrition among stable ambulatory patients with cirrhosis is lacking. We sought to investigate the prevalence of patents at risk of malnutrition (ARMN) among ambulatory patients with cirrhosis using the Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT) and the Malnutrition Universal Screening Tool (MUST) and compare their correlation to clinical outcomes. METHODS: Patients attending an outpatient liver cirrhosis clinic at a tertiary hospital were screened for ARMN using both the RFH-NPT and MUST (defined by a score of ≥2 for either tool). Differences in clinical outcomes after 6 mo were compared. RESULTS: There were 134 patients recruited. The RFH-NPT identified more ARMN patients compared with MUST (32.8% versus 8.2%; P < 0.01; Cohen κ, 0.27 [95% CI, 0.12-0.42]; P < 0.001). Fluid overload at recruitment was the only independent predictor of disagreement between the RFH-NPT and MUST (odds ratio [OR], 43.14; 95% CI, 8.70-214.00; P < 0.001). There was a trend toward an increased risk of mortality for ARMN patients by the RFH-NPT (hazard ratio, 3.58; 95% CI, 0.81-15.83; P = 0.06) but not by the MUST (P = 0.62). The incidence of hospital admissions in ARMN patients was higher by the RFH-NPT, with an incidence rate ratio of 13.27 (95% CI, 5.11-43.70; P < 0.001), but not in ARMN patients by the MUST (P = 0.85). Being ARMN by the RFH-NPT was the only independent predictor of hospital admissions (OR, 15.08; 95% CI, 2.47-91.98; P = 0.003). CONCLUSIONS: The RFH-NPT identified more ARMN patients when compared with the MUST, especially among patients with fluid overload. Patients at risk of malnutrition were at an increased risk of hospital admissions and possibly death.

Virtual monitoring for stable chronic hepatitis B patients does not reduce adherence to medications: A randomised controlled study.

INTRODUCTION: Chronic hepatitis B (CHB) remains common in endemic regions, causing significant healthcare burden. Patients with CHB may need to be adherent to nucleoside analogue (NA) for a long period of time to prevent complications. This study aims to investigate the safety, efficacy and patient experience of a virtual monitoring clinic (VMC) in monitoring stable patients taking NA for CHB. METHODS: Patients on NA and regular follow-up were randomised to either VMC alternating with doctors' clinic visit or to a control group in which they continued standard follow-up by doctors. Therapy adherence was measured by medication possession ratio (MPR) for NA therapy, incidence of virological breakthrough and hepatocellular carcinoma (HCC) development at two years of follow-up. Patient acceptance was measured on a Likert scale of 1-10. RESULTS: A total 192 patients completed follow-up: 94 and 98 patients in the VMC and control groups, respectively. Mean age was 60.6 ± 10.8 years, with 95.3% Chinese ethnicity and 64.1% males. Age, gender, race, educational, employment and financial status were similar in both groups. Upon study completion, the majority of patients - 76 (80.9%) in VMC group and 74 (75.5%) in control group - had MPR ≥0.8; 88.8% were satisfied and rated VMC better than a traditional follow-up clinic with doctors only. More than 85% of patients rated ≥8/10 on the Likert scale for VMC, and preferred VMC over traditional clinic visits. Clinical outcomes observed were HCC development in one (1.1%) in the VMC group and four (4.1%) in the control group (p = 0.369). Two (2.1%) and one (1.0%) virological breakthroughs were observed in the VMC and control groups, respectively (p = 0.615). No incidence of HCC or abnormal blood tests were missed in the VMC arm. DISCUSSION: VMC is a viable and safe clinical model for monitoring stable CHB patients on NA therapy without compromising patients' adherence to medications and is preferred by patients.

Longterm corticosteroid use after liver transplantation for autoimmune hepatitis is safe and associated with a lower incidence of recurrent disease.

Patients transplanted for autoimmune hepatitis (AIH) are at risk of recurrent disease. Our current practice is to maintain long-term low-dose corticosteroids with additional immunosuppressive agents. This study describes the implications on patients' outcomes, sepsis, and osteoporosis. We collected data on patients transplanted between January 1999 and October 2014 in a single center who survived for more than 6 months. AIH recurrence was diagnosed by a combination of histology, raised immunoglobulin G levels, and exclusion of other etiologies. Sepsis was defined as any infection that resulted in significant morbidity or mortality. Osteoporosis was defined as a bone densitometry T score of less than -2.0 or evidence of osteoporosis-related fractures. Outcomes were assessed using Kaplan-Meier survival analysis methods. Seventy-three AIH patients underwent liver transplantation with a median follow-up of 94 months (interquartile range, 55-144). The cohort was mainly Caucasian (78%), female (79%), with type 1 AIH (90%), and a mean age of 43 ± 15 years. Overall survival was 92%, 90%, 86%, and 73%, and regraft-free survival was 86%, 81%, 78%, and 64% at 1, 3, 5, and 10 years, respectively. Five patients developed AIH recurrence, giving recurrence rates of 0%, 4%, 6%, and 11% at 1, 3, 5, and 10 years, respectively. Pneumonia was the most common infection, but gastroenteritis and cholangitis were the most recurrent. Freedom from sepsis was 91%, 82%, 80%, and 63%, and freedom from osteoporosis was 100%, 94%, 82%, and 58% at 1, 3, 5, and 10 years, respectively. Longterm low-dose corticosteroid in combination with other immunosuppressive agents seems to reduce AIH recurrence without jeopardizing patient and graft survival. Sepsis and osteoporosis did not occur more often compared to the published literature on liver transplant recipients.

Perceptions of non-alcoholic fatty liver disease - an Asian community-based study.

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and is closely related to metabolic syndrome and its risk factors. Worldwide, epidemiological studies have reported NAFLD prevalence rates of 5% to 30% depending on geographical variations. While epidemiological data suggest a progressively increasing prevalence of metabolic risk factors in Singapore, there are limited data about NAFLD per se in the community. We aim to explore the prevalence and perceptions of NAFLD in Singapore. METHODS: Attendees at a gastroenterology public forum were enrolled in a cross-sectional observational study evaluating demographic, anthropometric and clinical information. The diagnosis of NAFLD was based on sonographic criteria. Metabolic syndrome was defined according to International Diabetes Federation guidelines. Perceptions of NAFLD were explored using a self-administered survey questionnaire. RESULTS: A total of 227 subjects were recruited, with NAFLD being diagnosed in 40% of the cohort. Relative to those without NAFLD, subjects with NAFLD had higher male preponderance, older age, higher body mass index, waist circumference and more metabolic syndrome (all P < 0.05). Although 71.2% subjects had heard about NAFLD before, only 25.4% of them felt that they were at risk of NAFLD. Comparable responses were observed in subjects with no metabolic risk factors relative to subjects with one or more metabolic risk factors (P > 0.05). Of note, 75.6% of subjects with one or more metabolic risk factors did not think that they were at risk of NAFLD. CONCLUSION: Our study suggests a significant local prevalence of NAFLD in the community including non-obese individuals. Considering the tendency to underestimate risk of NAFLD, enhanced public education about NAFLD is warranted to improve understanding.

The impact of irritable bowel syndrome on health-related quality of life: a Singapore perspective.

BACKGROUND: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder. The prevalence of IBS in Asian countries varies from 2.9% to 15.6%. IBS does not result in increased mortality, but is associated with psychological distress and disruption of work and sleep. Consequently, the evaluation of health-related quality of life (HRQoL) is an important outcome measure for patients with IBS since it provides a holistic assessment of the patient's emotional, social and physical function. However, some HRQoL tools can be time-consuming to apply. EQ-5D is a brief HRQoL tool which has been validated in the Western IBS population but has thus far not been used in Asia. This study was conducted to determine whether persons with self-reported symptoms that met the Rome III criteria for IBS had a poorer quality of life than those without these symptoms. We also aimed to determine which specific aspects of quality of life were most affected and whether any risk factors distinguished those with and without IBS. METHODS: Self-administered questionnaires which included the Rome III diagnostic questionnaire modules for IBS and the EQ-5D questionnaire were obtained from participants of a health symposium in Singapore on 31th October 2010. IBS was diagnosed based on the Rome III Criteria. The main outcome measure was the EQ-5D index score. The relationship between the presence of IBS and the EQ-5D index score, individual dimensions of EQ-5D and demographic risk factors were examined. RESULTS: 449 completed questionnaires were analyzed. The mean EQ-5D index score for IBS was 0.739 which was a significant reduction compared to non-IBS participants [-0.11 (95% CI: -0.15 to -0.07), p<0.001]. Multivariate analysis showed that IBS was significantly associated with younger age and higher education level. Of the five EQ-5D dimensions, IBS sufferers were significantly affected in mobility, anxiety or depression, usual activity and pain. There was a "dose related" increase in likelihood of having IBS with increased severity of pain and anxiety or depression. CONCLUSION: IBS sufferers have significantly poorer quality of life. Assessment of HRQoL in IBS using the EQ-5D should be considered in further studies and routine clinical practice.
