Liver transplantation is the treatment of choice for patients with liver failure secondary to chronic hepatitis B. However, liver transplantation is complicated by the risk of recurrent hepatitis B virus infection, which significantly impairs graft and patient survival. ⋯ However, current approaches continue to be hampered by the extremely high cost of treatment and the emergence of drug-resistant viral mutations. Ongoing studies are necessary to establish the most cost-effective approaches to prevent recurrent hepatitis B virus infection after liver transplantation.

Randomized Controlled Trial
Randomized study of the safety and efficacy of fish oil (omega-3 fatty acid) supplementation with dietary and exercise counseling for the treatment of antiretroviral therapy-associated hypertriglyceridemia.
Omega-3 fatty acids (fish oils) reduce fasting serum triglyceride levels and cardiovascular disease risk in individuals without HIV infection. Whether omega-3 fatty acid supplementation can reduce hypertriglyceridemia associated with antiretroviral therapy is not known. ⋯ Supplementation with omega-3 fatty acids in combination with dietary and exercise counseling was well tolerated and reduced fasting triglyceride levels in patients receiving antiretrovirals. To what extent the increase in low-density lipoprotein cholesterol levels observed in patients assigned this intervention is attributable to omega-3 fatty acid supplementation and whether this increase attenuates any benefit in lowering triglyceride levels is unclear. Given these results, further investigation of omega-3 fatty acid supplementation for the treatment of hypertriglyceridemia in HIV-infected patients is warranted.

The incidence of enteric (typhoid) fever in travelers is estimated to be approximately 3-30 cases per 100,000 travelers to developing countries. Recently, it is become clear that travelers who are visiting friends and relatives, especially travelers to the Indian subcontinent, seem to be the most vulnerable to enteric fever and require special attention for prevention. ⋯ Typhoid vaccination is recommended for most travelers to moderate- to high-risk countries. Because of the nonspecific clinical presentation of enteric fever, a high index of suspicion is important in febrile travelers who have traveled to areas of endemicity.

Sepsis is the leading cause of death in surgical intensive care units and is a major cause of morbidity and mortality in neonatal and medical intensive care units. The Centers for Disease Control and Prevention estimates that, in the United States alone, approximately 500,000 people develop sepsis and 175,000 people die each year. Sepsis is a growing problem; its incidence has tripled from 1972 to 1992. ⋯ The apoptosis of gastrointestinal epithelial cells may compromise the integrity of the bowel wall, resulting in translocation of bacteria or endotoxins into the systemic circulation. The potential importance of apoptosis in the pathophysiology of sepsis is illustrated by results from animal models that demonstrate that blocking lymphocyte apoptosis improves survival in sepsis. A variety of strategies to inhibit apoptosis may ultimately provide an effective therapy for this highly lethal disorder.

Randomized Controlled Trial
Strategy of following voriconazole versus amphotericin B therapy with other licensed antifungal therapy for primary treatment of invasive aspergillosis: impact of other therapies on outcome.
In a previous randomized trial of voriconazole versus amphotericin B deoxycholate for primary therapy of invasive aspergillosis, voriconazole demonstrated superior efficacy and better survival. In that trial, treatment with voriconazole or amphotericin B deoxycholate could be followed with other licensed antifungal therapies (OLAT). Here, we report the impact of OLAT on the outcome of patients with invasive aspergillosis. ⋯ This study highlights the limited efficacy of salvage antifungal therapy, including therapy with lipid formulations of amphotericin B, and demonstrates the importance of effective initial therapy in invasive aspergillosis.
