BACKGROUND: Although highly prevalent, little is known about the economic impact of functional dyspepsia (FD). AIMS: To quantify FD patients' health care utilisation patterns and to estimate direct and indirect costs of FD to patients. METHODS: ICD-9 codes identified adult patients with dyspepsia. A validated questionnaire was mailed to patients who met Rome III criteria for FD. RESULTS: Three hundred and fifty-five patients met all inclusion criteria. The response rate was 63%. The respondents' mean age was 50 (14) years; 75% were women; 52% of respondents rated their FD as moderate. Patients reported 3 visits (mean) to their PCP over 12 months; 75% reported having blood work, 92% an EGD, 59% an ultrasound and 40% a CT scan. The direct cost of testing using Medicare reimbursement rates per patient was $582. To treat FD symptoms, 89% tried dietary changes, 89% over-the-counter medications, 87% prescription medications and 25% alternative therapies. Mean patient expenditure over the last year was $246 for OTC medications (range $0-12,000), $290 for co-payments (range $0-9,000) and $110 for alternative treatments (range $0-3,741). Total mean direct cost yearly to patients was $699. In the 7 days prior to completing the questionnaire, respondents reported a mean of 1.4 h absence from work. Extrapolating the results to the US population, we conservatively calculate the costs of FD were $18.4 billion in 2009. CONCLUSIONS: Functional dyspepsia patients incur significant direct and indirect costs and work productivity is impaired by dyspeptic symptoms.

Patients with chronic atrophic gastritis have long-term gastric hypoacidity, and secondary hypergastrinaemia. Some also develop gastric ECL cells carcinoids (type 1 GC). Most type 1 GC remain indolent, but some metastasise. Patients undergo surveillance, and some are treated with somatostatin analogues, endoscopic resection or surgery. Netazepide (YF476) is a highly selective, potent and orally active gastrin receptor antagonist, which has anti-tumour activity in various rodent models of gastric neoplasia driven by hypergastrinaemia. Netazepide has been studied in healthy volunteers.

BACKGROUND: Some of the most important questions relating to the use of biological therapy in inflammatory bowel diseases concern the duration of maintenance therapy. AIM: To assess the disease course and frequency of relapse of Crohn’s disease (CD) following discontinuation of biological therapy, and to determine predictive factors for relapse. METHODS: One hundred twenty-one CD patients who had achieved clinical remission following 1 year of biological therapy and for whom biological therapy was then discontinued participated in this prospective observational study. Eighty-seven CD patients had received infliximab and 34 adalimumab. The definition of relapse was an increase of >100 points in CDAI to at least a CDAI of 150 points. RESULTS: Biological therapy was restarted within 1 year of treatment cessation in 45% of patients. Logistic regression analysis revealed that previous biological therapy (P = 0.011) and dose intensification during the 1-year course of biological therapy (P = 0.024) were associated with the need for and the time to the restarting of biological therapy. Smoking was observed to have an effect that was not statistically significant (P = 0.053). CONCLUSIONS: Biological therapy was restarted a median of 6 months after discontinuation in almost half of Crohn’s disease patients in who had been in clinical remission following 1 year of biological therapy. These results suggest that, in the event of the presence of certain predictive factors, biological therapy should probably be continued for more than 1 year by most patients.

Long-acting lanreotide (LAN) 120 mg every 4 weeks reduces liver volume (LV) in patients with polycystic liver diseases (PCLD). Animal studies demonstrated that the inhibition of hepatic and renal cystogenesis is dose dependent.

Aprepitant (Emend, Merck Sharp & Dohme Ltd, Haarlem, the Netherlands), a neurokinin-1 receptor antagonist, prevents vomiting in a range of conditions. No data are available on its use in children with cyclical vomiting syndrome (CVS).


The prevalence of hepatitis C virus (HCV) infection in Egypt is the highest in the world, yet the total economic burden has not been quantified. Improved understanding of costs and the impact of treatment strategies will provide for better allocation of resources to reduce HCV disease and economic burden.

The development of alcohol dependence is associated with significant morbidity and mortality. For the majority of affected people the most appropriate goal, in terms of drinking behaviour, is abstinence from alcohol. Psychosocial intervention is the mainstay of the treatment but adjuvant pharmacotherapy is also available and its use recommended.

The human virome consists of animal-cell viruses causing transient infections, bacteriophage (phage) predators of bacteria and archaea, endogenous retroviruses and viruses causing persistent and latent infections. High-throughput, inexpensive, sensitive sequencing methods and metagenomics now make it possible to study the contribution dsDNA, ssDNA and RNA virus-like particles make to the human virome, and in particular the intestinal virome.
