["Artificial liver"].

Abstract

Acute liver failure is a life-threatening condition since conventional medical treatments have little effect on survival. Artificial liver support systems based on blood detoxification alone have proven to be ineffective. A liver support system should carry out essential functions such as the phase I reaction in which lipid-soluble toxic substance are rendered water-soluble by the enzyme system of the cytochrome P450 and NADPH-cytochrome reductase, and are therefore conjugated by the phase II reaction, before excretion. Liver support systems should be capable of sustaining patients until an organ is available for liver transplantation (bridging treatment), or improving the survival in patients for whom liver transplantation is not a therapeutic option. Recent advances in cell biology and tissue culture techniques have led the way for potential clinical use of isolated hepatocytes so that they are now an important element of bioartificial liver (BAL) support devices. Some of these BAL are currently under clinical investigation in the USA and Europe, and the results of the prospective controlled trials will be soon available.

Smallpox vaccination and myopericarditis: a clinical review.

Smallpox is a devastating viral illness that was eradicated after an aggressive, widespread vaccination campaign. Routine U.S. childhood vaccinations ended in 1972, and routine military vaccinations ended in 1990. Recently, the threat of bioterrorist use of smallpox has revived the need for vaccination. Over 450,000 U.S. military personnel received the vaccination between December 2002 and June 2003, with rates of non-cardiac complications at or below historical levels. The rate of cardiac complications, however, has been higher than expected, with two confirmed cases and over 50 probable cases of myopericarditis after vaccination reported to the Department of Defense Smallpox Vaccination Program. The practicing physician should use the history and physical, electrocardiogram, and cardiac biomarkers in the initial evaluation of a post-vaccination patient with chest pain. Echocardiogram, cardiac catheterization, magnetic resonance imaging, nuclear imaging, and cardiac biopsy may be of use in further workup. Treatment is with non-steroidal anti-inflammatory agents, four to six weeks of limited exertion, and conventional heart failure treatment as necessary. Immune suppressant therapy with steroids may be uniquely beneficial in myopericarditis related to smallpox vaccination, compared with other types of myopericarditis. If a widespread vaccination program is undertaken in the future, many more cases of post-vaccinial myopericarditis could be seen. Practicing physicians should be aware that smallpox vaccine-associated myopericarditis is a real entity, and symptoms after vaccination should be appropriately evaluated, treated if necessary, and reported to the Vaccine Adverse Events Reporting System.
