RESUMO
OBJECTIVES: In this study we retrospectively reviewed A. baumannii meningitis cases treated with tigecycline including regimens and evaluated the efficacy of tigecycline in the therapy. PATIENTS AND METHODS: Study was performed in seven tertiary-care educational hospitals from five cities of Turkey and one center from France. We extracted data and outcomes of all adult (aged >18) patients with culture proven A. baumannii meningitis treated with tigecycline including antibiotic therapy until April 2016. RESULTS: A total of 23 patients (15 male and eight female) fulfilled our inclusion criteria. All Acinetobacter strains were carbapenem-resistant and susceptible to tigecycline. Six cases received tigecycline monotherapy while 17 received tigecycline including combination therapy (10 with colistin, 4 with netilmicin, 3 with amikacin, 4 with meropenem). Seven of 23 cases (30%) died during the tigecycline including therapy (1 in monotherapy, 4 in colistin, 2 in netilmicin, 1 amikacin, one case received tigecyclineâ¯+â¯netilmicin followed by tigecyclineâ¯+â¯colistin). Hence, overall end of treatment (EOT) success was 70%. However, since further 27% died due to additional nosocomial infections, overall clinical success (relieved symptoms at the EOT and one-month post-therapy survival without any relapse or reinfection) decreased to 43%. CONCLUSION: We conclude that tigecycline may be an alternative in the salvage treatment of nosocomial multidrug-resistant Acinetobacter spp. meningitis. Acinetobacter spp. Meningitis.

BACKGROUND/AIMS: The natural course and clinical outcome of hepatitis C virus (HCV) infection is related to the interaction between HCV and the immune response of the host. Only a limited number of studies have investigated the role of mannose-binding lectin (MBL) levels in HCV infection. The aim of the present study was to explore the relationship between MBL levels and gene polymorphisms on treatment response in patients with chronic hepatitis C (CHC). MATERIALS AND METHODS: Serum MBL levels from 50 CHC patients who completed treatment at least 24 weeks before the present study and 75 healthy HCV-negative controls were measured. In addition, the presence of codon 54 mutations was investigated. Correlational analyses were performed to determine relationships between MBL levels and treatment response. RESULTS: In patients, mean serum MBL levels were lower and the rate of codon 54 mutations was higher. However, these differences were not statically significant. In both patients and controls, serum MBL levels were significantly lower in individuals with codon 54 mutations. Moreover, serum MBL levels and the rate of the codon 54 mutation were similar in patients regardless of treatment response. CONCLUSION: Our findings suggest that low MBL levels do not increase the susceptibility for HCV infection. Furthermore, MBL levels were not found to have a significant effect on the course of the disease or treatment response.
