    The aim of this observational prospective study was to compare the effect of fosfomycin tromethanol (FT) and carbapenems (meropenem or imipenem cilastatin) in the treatment of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli-related complicated lower urinary tract infection (CLUTI). Inclusion criteria were: patients who were aged >18 yr with dysuria or problems with frequency or urgency in passing urine; those with >20 leukocytes/mm3 in urine microscopy and culture-proven ESBL-producing carbapenem or FT-sensitive E. coli in the urine (>10 5 cfu/mm3); no leukocytosis or fever; and who were treated with FT (oral 3 g sachet x 1 every other night, three times) or carbapenems between March 2005 and January 2006 in our outpatient clinic and hospital. A total of 47 CLUTI attacks in 47 patients (27 FT group, 20 carbapenem group) were observed prospectively. Clinical and microbiological success in the carbapenem and FT groups was similar (19/20 vs 21/27 and 16/20 vs 16/27 p>0.05). Drug acquisition costs were significantly lower in the FT group (p<0.001). Although it is not a randomized controlled study, these data show that FT may be a suitable, effective and cheap alternative in the treatment of ESBL-producing E. coli-related CLUTI. © E.S.I.F.T. srl.

    Investigation of bacterial and viral etiology in community acquired central nervous system infections with molecular methods; [Toplum Kökenli Santral Sinir Sistemi Enfeksiyonlarinda Bakteriyel ve Viral Etiyolojinin Moleküler Yöntemlerle Deǧerlendirilmesi]
    (Ankara Microbiology Society, 2017) Kahraman H.; Tünger A.; Şenol S.; Gazi H.; Avci M.; Örmen B.; Türker N.; Atalay S.; Köse S.; Ulusoy S.; Taşbakan M.I.; Sipahi O.R.; Yamazhan T.; Gülay Z.; Çavuş S.A.; Pullukçu H.
    In this multicenter prospective cohort study, it was aimed to evaluate the bacterial and viral etiology in community-acquired central nervous system infections by standart bacteriological culture and multiplex polymerase chain reaction (PCR) methods. Patients hospitalized with central nervous system infections between April 2012 and February 2014 were enrolled in the study. Demographic and clinical information of the patients were collected prospectively. Cerebrospinal fluid (CSF) samples of the patients were examined by standart bacteriological culture methods, bacterial multiplex PCR (Seeplex meningitis-B ACE Detection (Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae, Listeria monocytogenes, Group B streptococci) and viral multiplex PCR (Seeplex meningitis-VI ACE Detection kits herpes simplex virus-1(HSV1), herpes simplex virus-2(HSV2), varicella zoster virus (VZV), cytomegalovirus (CMV), Epstein Barr virus (EBV) and human herpes virus 6 (HHV6)) (Seeplex meningitis-V2 ACE Detection kit (enteroviruses)). Patients were classified as purulent meningitis, aseptic meningitis and encephalitis according to their clinical, CSF (leukocyte level, predominant cell type, protein and glucose (blood/CSF) levels) and cranial imaging results. Patients who were infected with a pathogen other than the detection of the kit or diagnosed as chronic meningitis and other diseases during the follow up, were excluded from the study. A total of 79 patients (28 feMale, 51 Male, aged 42.1 ±18.5) fulfilled the study inclusion criteria. A total of 46 patients were classified in purulent meningitis group whereas 33 were in aseptic meningitis/encephalitis group. Pathogens were detected by multiplex PCR in 41 patients. CSF cultures were positive in 10 (21.7%) patients (nine S.pneumoniae, one H.influenzae) and PCR were positive for 27 (58.6%) patients in purulent meningitis group. In this group one type of bacteria were detected in 18 patients (14 S.pneumoniae, two N.meningitidis, one H.influenzae, one Lmonocytogenes). Besides, it is noteworthy that multiple pathogens were detected such as bacteria-virus combination in eight patients and two different bacteria in one patient. In the aseptic meningitis/encephalitis group, pathogens were detected in 14 out of 33 patients; single type of viruses in 11 patients (seven enterovirus, two HSV1, one HSV2, one VZV) and two different viruses were determined in three patients. These data suggest that multiplex PCR methods may increase the isolation rate of pathogens in central nervous system infections. Existence of mixed pathogen growth is remarkable in our study. Further studies are needed for the clinical relevance of this result.
