Expert opinion on emerging drugs

Sepsis remains a major cause of death in intensive care units. Despite an intense research, a new drug that is effective in reducing mortality in sepsis is still awaited. ⋯ New licensed antibiotics will offer the opportunity to refine the treatment choices. Direct hemoperfusion using polymyxin B-immobilized fiber column may be an option in sepsis due to Gram-negative bacilli. Among non-antibiotic drugs, new ongoing studies will clarify the role of drotrecogin alfa (activated) and low dose hydrocortisone. The modulation of monocytic human leukocyte antigen-DR seems the most prominent treatment. The use of cardiovascular drugs requires well-conducted clinical trials. The regulation of high mobility group box 1, adenosine blockade or correction of the impaired energy production is still at the experimental level.

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide. Although patients with early-stage disease have a good prognosis, there has been no effective therapy available for those with advanced disease. Despite the death risk of patients with advanced HCC being reduced with sorafenib therapy, many patients eventually turn out to be refractory to this therapy. Thus, treatment of HCC remains an urgent health concern. ⋯ Understanding the mechanisms of action, safety and efficacy of these new agents and new methods of combining these drugs may help prolong overall survival of patients with HCC and reduce disease recurrence after surgery or ablative therapies.
