Background-At least 10-15% of patients with reflux symptoms have a normal endoscopy and physiological levels of acid reflux on pH monitoring. Such patients with 50% or more of symptoms associated with acid reflux episodes have "a positive symptom index" (SI), and it has been proposed that this defines the "sensitive oesophagus". Aim-To test the response to omeprazole 20 mg twice daily for four weeks ofpatients with normal levels of acid reflux using a randomised, placebo controlled, double blind, cross-over design. Patients Conclusion-Omeprazole improves symptoms in 11 of 18 patients with normal endoscopy and pH monitoring, particularly those with a positive SI. This supports the theory that such patients have an oesophagus which is "sensitive" to acid reflux and are part of the GORD spectrum.
Conclusion-Nearly three quarters of patients previously diagnosed as having oesophagitis still had significant morbidity related to gastro-oesophageal reflux disease more than 10 years after diagnosis. Some quality of life scores were significantly lower than those of the general population.
This report contains new and follow-up metric data relating to the eight main recommendations of the Lancet Standing Commission on Liver Disease in the UK, which aim to reduce the unacceptable harmful consequences of excess alcohol consumption, obesity, and viral hepatitis. For alcohol, we provide data on alcohol dependence, damage to families, and the documented increase in alcohol consumption since removal of the above-inflation alcohol duty escalator. Alcoholic liver disease will shortly overtake ischaemic heart disease with regard to years of working life lost. The rising prevalence of overweight and obesity, affecting more than 60% of adults in the UK, is leading to an increasing liver disease burden. Favourable responses by industry to the UK Government's soft drinks industry levy have been seen, but the government cannot continue to ignore the number of adults being affected by diabetes, hypertension, and liver disease. New direct-acting antiviral drugs for the treatment of chronic hepatitis C virus infection have reduced mortality and the number of patients requiring liver transplantation, but more screening campaigns are needed for identification of infected people in high-risk migrant communities, prisons, and addiction centres. Provision of care continues to be worst in regions with the greatest socioeconomic deprivation, and deficiencies exist in training programmes in hepatology for specialist registrars. Firm guidance is needed for primary care on the use of liver blood tests in detection of early disease and the need for specialist referral. This report also brings together all the evidence on costs to the National Health Service and wider society, in addition to the loss of tax revenue, with alcohol misuse in England and Wales costing £21 billion a year (possibly up to £52 billion) and obesity costing £27 billion a year (treasury estimates are as high as £46 billion). Voluntary restraints by the food and drinks industry have had little effect on disease burden, and concerted regulatory and fiscal action by the UK Government is essential if the scale of the medical problem, with an estimated 63 000 preventable deaths over the next 5 years, is to be addressed.
Hepatic encephalopathy (HE) is defined as a metabolically induced, potentially reversible, functional disturbance of the brain that may occur in acute or chronic liver disease. Standardized nomenclature has been proposed but a standardized approach to the treatment, particularly of persistent, episodic and recurrent encephalopathy associated with liver cirrhosis has not been proposed. This review focuses on the pathogenesis and treatment of HE in patients with cirrhosis. The pathogenesis and treatment of hepatic encephalopathy in fulminant hepatic failure is quite different and is reviewed elsewhere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
