RESUMEN
STUDY OBJECTIVE: To evaluate the effectiveness and hepatotoxicity of statins in patients who are seropositive for hepatitis C virus (HCV). DESIGN: Retrospective review of a registry of patients with HCV. SETTING: Veterans Affairs Medical Center. PATIENTS: One hundred forty-six male patients who were seropositive for HCV and had received statin therapy between January 1, 1995, and September 9, 2003. MEASUREMENTS AND MAIN RESULTS: Demographic and clinical data were collected for each patient; lipid and alanine aminotransferase (ALT) levels at baseline (within 6 mo of starting a statin), at 3 and 6 months after starting a statin, and at long-term follow-up (mean 22 mo) were also recorded. The primary efficacy end point was a significant decrease from baseline to long-term follow-up low-density lipoprotein cholesterol (LDL) level; the primary safety end point was a significant increase from baseline in ALT level. The mean change in LDL level was a reduction of 22% (p<0.01). No significant increases in ALT levels were observed; only one patient discontinued therapy due to ALT level elevations greater than 3 times the upper limit of normal. CONCLUSION: In men seropositive for HCV, statins were effective in reducing LDL levels and did not result in significant increases in ALT levels from baseline. Thus, statin therapy should be considered for patients with HCV who are at risk for coronary heart disease and do not have significantly elevated serum transaminase levels at baseline.

OBJECTIVE: To review the literature on the use of the antibiotic lock technique (ALT) as a treatment option for patients with highly needed catheters. DATA SOURCES: MEDLINE and International Pharmaceutical Abstracts were searched (1980-August 2004). Search terms included antibiotic lock, catheter infection, and topical treatment. STUDY SELECTION AND DATA EXTRACTION: Articles describing use of ALT in the treatment of catheter infections in humans and studies evaluating in vitro stability of antibiotics were included. DATA SYNTHESIS: ALT has been used in patients with highly needed catheters, usually for parenteral nutrition, cancer chemotherapy, or dialysis. Catheters are considered highly needed when removal is not feasible or desirable due to lack of alternative injection sites for required therapy. Success rates in saving the infected catheter have been variable and may depend on the infecting organism. In addition, there are conflicting data in terms of compatibility of antibiotics with heparin solutions. CONCLUSIONS: Consensus appears to be that the ALT can be tried for patients with highly needed catheters when infection with coagulase-negative staphylococci is documented and no systemic signs of sepsis, such as hypotension, are evident. Most of these patients are likely to need systemic therapy as well. Infection of the catheter associated with systemic gram-negative bacteremia or fungemia will most likely require removal of the catheter to prevent systemic complications. Additional research with the ALT is warranted given unanswered questions.
