ABSTRACT
Due to the introduction of newer, more efficacious treatment options, there is a pressing need for policy makers and public health officials to develop or adapt national hepatitis C virus (HCV) control strategies to the changing epidemiological landscape. To do so, detailed, country-specific data are needed to characterize the burden of chronic HCV infection. In this study of 17 countries, a literature review of published and unpublished data on HCV prevalence, viraemia, genotype, age and gender distribution, liver transplants and diagnosis and treatment rates was conducted, and inputs were validated by expert consensus in each country. Viraemic prevalence in this study ranged from 0.2% in Hong Kong to 2.4% in Taiwan, while the largest viraemic populations were in Nigeria (2 597 000 cases) and Taiwan (569 000 cases). Diagnosis, treatment and liver transplant rates varied widely across the countries included in this analysis, as did the availability of reliable data. Addressing data gaps will be critical for the development of future strategies to manage and minimize the disease burden of hepatitis C.

The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets-"WHO Targets" (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.

Factors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman); however, HCV-related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high-treatment rate will contribute to a reduction in total cases and HCV-related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV-related morbidity and mortality.

Hand hygiene is a growing concern among populations and is a crucial element in ensuring patient safety in a healthcare environment. Numerous management efforts have been conducted in that regard, including education, awareness and observations. To better evaluate the possible impact of technology on a healthcare setting, we observed the impact of a particular niche technology developed as an answer to the growing hand hygiene concerns. A study was conducted at Salmaniya Medical Complex (SMC) in Bahrain on a total of 16 Coronary Care Unit (CCU) beds where the system was installed, and the hand hygiene activity of healthcare workers (HCWs) in this area was monitored for a total period of 28 days. Comments, remarks and suggestions were noted, and improvements were made to the technology during the course of the trial. While resistance to change was significant, overall results were satisfactory. Compliance with hand hygiene techniques went from 38-42% to 60% at the beginning of the trial and then increased to an average of 75% at the end of the 28-day trial. In some cases, compliance peaked at 85% or even at 100%. Our case study demonstrates that technology can be used effectively in promoting and improving hand hygiene compliance in hospitals, which is one way to prevent cross-infections, especially in critical care areas.

The clinical course of follicular lymphoma (FL) is well known. Although it is a chemosensitive disease, thereby allowing substantial palliation, recurrence is the rule; only a small subset who presents with limited stage disease is cured. Multiple attempts have been made over the past two decades to improve the survival of patients with FL, and a large number of phase III trials have been reported. These have included a variety of different therapeutic interventions, such as combination chemotherapy, recombinant interferons, new cytotoxic drugs, and immunologic agents. Most studies have not demonstrated that the use of a particular therapy convincingly prolongs survival. Follicular lymphoma cells express CD20 and are associated in most cases with the t(14:18) chromosomal translocation. Rituximab is a chimeric monoclonal antibody directed against the B-cell CD20 antigen, which has been utilized for the therapy of B-cell non-Hodgkin's lymphoma. Rituximab was shown to be active in FL, and studies of its effectiveness in combination with cytotoxic chemotherapy to increase the response rate are forthcoming.

BACKGROUND: Rosiglitazone maleate (Avandia, SmithKline Beecham, Philadelphia, Pennsylvania) is a new oral hypoglycemic agent approved for the treatment of type 2 diabetes. It acts primarily by increasing insulin sensitivity. In controlled trials, there has been no evidence of rosiglitazone-induced hepatocellular injury. OBJECTIVE: To report a case of hepatocellular injury in a patient receiving rosiglitazone. DESIGN: Case report. SETTING: Community teaching hospital. PATIENT: 61-year-old man receiving rosiglitazone, 4 mg/d for 2 weeks. INTERVENTION: Discontinuation of rosiglitazone therapy. MEASUREMENTS: Clinical evaluation and assessment of liver function test results were done daily during hospitalization and periodically after discharge. The outpatient record was also reviewed. RESULTS: After receiving rosiglitazone for 2 weeks, the patient presented with anorexia, vomiting, and abdominal pain. Liver function tests revealed severe hepatocellular injury. Discontinuation of rosiglitazone therapy led to rapid improvement of liver function and resolution of symptoms. CONCLUSION: Rosiglitazone may be associated with hepatocellular injury. We believe that patients receiving rosiglitazone should have liver enzyme levels monitored earlier and more frequently than initially recommended.
