    <p>Abstract</p> <p>Background</p> <p>This study determined macrolide resistance genotypes in clinical isolates of <it>Streptococcus pneumoniae </it>from multiple medical centers in Lebanon and assessed the serotype distribution in relation to these mechanism(s) of resistance and the source of isolate recovery.</p> <p>Methods</p> <p>Forty four macrolide resistant and 21 macrolide susceptible <it>S. pneumoniae </it>clinical isolates were tested for antimicrobial susceptibility according to CLSI guidelines (2008) and underwent molecular characterization. Serotyping of these isolates was performed by Multiplex PCR-based serotype deduction using CDC protocols. PCR amplification of macrolide resistant <it>erm </it>(encoding methylase) and <it>mef </it>(encoding macrolide efflux pump protein) genes was carried out.</p> <p>Results</p> <p>Among 44 isolates resistant to erythromycin, 35 were resistant to penicillin and 18 to ceftriaxone. Examination of 44 macrolide resistant isolates by PCR showed that 16 isolates harbored the <it>erm</it>(B) gene, 8 isolates harbored the <it>mef </it>gene, and 14 isolates harbored both the <it>erm</it>(B) and <it>mef </it>genes. There was no amplification by PCR of the <it>erm</it>(B) or <it>mef </it>genes in 6 isolates. Seven different capsular serotypes 2, 9V/9A,12F, 14,19A, 19F, and 23, were detected by multiplex PCR serotype deduction in 35 of 44 macrolide resistant isolates, with 19F being the most prevalent serotype. With the exception of serotype 2, all serotypes were invasive. Isolates belonging to the invasive serotypes 14 and 19F harbored both <it>erm</it>(B) and <it>mef </it>genes. Nine of the 44 macrolide resistant isolates were non-serotypable by our protocols.</p> <p>Conclusion</p> <p>Macrolide resistance in <it>S. pneumoniae </it>in Lebanon is mainly through target site modification but is also mediated through efflux pumps, with serotype 19F having dual resistance and being the most prevalent and invasive.</p

    Profile of opportunistic infections in HIV-infected patients at a tertiary care center in Lebanon

    No full text
    Objectives: According to statistics published in December 2007 by the National AIDS Program, Lebanon is home to 1056 individuals infected with HIV. Little is known about the clinical profile of opportunistic infections (OIs) and AIDS defining illnesses (ADIs) and their relative contribution to the morbidity and mortality of HIV-infected patients in Lebanon. The aim of this study is to describe the spectrum of OIs and ADIs in HIV-infected patients diagnosed and/or treated at the American University of Beirut Medical Center (AUBMC) in Lebanon. Methods: Data on various OIs and ADIs were collected from the medical records of patients with HIV infection who were diagnosed or received their medical care at AUBMC from 1984 to January 2008. Results: Eighty-nine HIV-infected patients were included in the analysis. The incidence of ADIs was 72% (64/89). The most commonly diagnosed OIs were cerebral toxoplasmosis (21%), followed by fungal infections (17%). The majority of ADIs (75%) occurred when the CD4 count was below 200 cells/mm3. Conclusion: Clinical guidelines for the prevention of OIs in HIV-infected individuals have been developed on the basis of natural history data collected in industrialized countries. Our results can be used to define local priorities for opportunistic infection prophylaxis. Keywords: HIV, Opportunistic infections, Lebano

    Monotherapeutic options for carbapenem resistant infections are limited. Studies suggest that combination therapy may be associated with better outcomes than monotherapies. However, this is still controversial. This study assessed, the efficacy of combination therapy against carbapenem resistant Enterobacteriaceae harboring singly various ESBL or carbapenemase encoding genes. Thus, four isolates harboring either blaCTXM-15, blaCTXM-15 and blaOXA-48, blaNDM-1, or blaKPC-2 genes were selected for testing. Minimal Inhibitory Concentration (MIC) was determined by broth dilution method. Gene transcript levels on single and combined treatments were done in vitro and in vivo by q RT-PCR. Assessment of treatments was done in BALB/c mice according to a specific protocol. As such, the qRT-PCR revealed a significant decrease of transcript levels in all isolates upon using rifampicin or tigecycline, singly or in combination with colistin. However, variable levels were obtained using colistin singly or in combination with meropenem or fosfomycin. In vivo assessment showed that all combinations used were effective against isolates harboring blaCTXM-15, blaOXA-48, and blaNDM-1. Conversely, the most significant combination against the isolate harboring blaKPC-2 gene was colistin with carbapenem, fosfomycin, or kanamycin. As a conclusion, combination therapy selected based on the type of carbapenemase produced, appeared to be non-toxic and might be effective in BALB/c mice. Therefore, the use of a rationally optimized combination therapy might lead to better results than monotherapy, however, clinical trials are needed for human consumption

    Multi-drug resistant Acinetobacter species: a seven-year experience from a tertiary care center in Lebanon

    No full text
    Abstract Background Acinetobacter species have become increasingly common in the intensive care units (ICU) over the past two decades, causing serious infections. At the American University of Beirut Medical Center, the incidence of multi-drug resistant Acinetobacter baumannii (MDR-Ab) infections in the ICU increased sharply in 2007 by around 120%, and these infections have continued to cause a serious problem to this day. Methods We conducted a seven-year prospective cohort study between 2007 and 2014 in the ICU. Early in the epidemic, a case-control study was performed that included MDR-Ab cases diagnosed between 2007 and 2008 and uninfected controls admitted to the ICU during the same time. Results The total number of patients with MDR-Ab infections diagnosed between 2007 and 2014 was 128. There were also 99 patients with MDR-Ab colonization without evidence of active infection between 2011 and 2014. The incidence of MDR-Ab transmission was 315.4 cases/1000 ICU patient-days. The majority of infections were considered hospital-acquired (84%) and most consisted of respiratory infections (53.1%). The mortality rate of patients with MDR-Ab ranged from 52% to 66%. Conclusion MDR-Ab infections mostly consisted of ventilator-associated pneumonia and were associated with a very high mortality rate. Infection control measures should be reinforced to control the transmission of these organisms in the ICU
