RESUMO
Background: Invasive fungal infections have presented a challenge in treatment. In the past, it was known that the frontrunner in such infections is Candida albicans with little emphasis placed on non-albicans Candida species (NAC). Studies worldwide have shown a rise in fungal infections attributed to non-albicans Candida species. The aim of this study is to describe the epidemiology of NAC infections along with an overview of resistance in Lebanese hospitals. Methods: This is a two-year observational multi-central descriptive study. Between September 2016 and May of 2018, a total of 1000 isolates were collected from 10 different hospitals distributed all over the country. For the culture, Sabouraud Dextrose Agar was used. Antifungal Susceptibility was evaluated by determining the Minimum Inhibitory Concentration (MIC) in broth (microdilution) of the different antifungal treatments. Results: Out of the 1000 collected isolates, Candida glabrata, being the most isolated species (40.8%), followed by Candida tropicalis: 231(23.1%), Candida parapsilosis: 103(10.3%), and other NAC species at lower percentage. Most of these isolates (88.67%) were susceptible to posaconazole, 98.22% were susceptible to micafungin, and 10% were susceptible to caspofungin. Conclusion: The change of etiology of fungal infections involving a significant increase in NAC cases is alarming due to the different antifungal susceptibility patterns and the lack of local guidelines to guide the treatment. In this context, proper identification of such organisms is of utmost importance. The data presented here can help in establishing guidelines for the treatment of candida infections to decrease morbidity and mortality. Future surveillance data are needed.

BACKGROUND: Brucella are small, nonmotile, intracellular, and aerobic gram-negative bacteria. Of the 10 species that currently form the genus Brucella, 5 were shown to be pathogenic in humans. REVIEW SUMMARY: The epidemiology, clinical manifestations, diagnosis and imaging, and treatment of neurobrucellosis will be reviewed.Brucellosis's transmission to humans occurs by direct contact with contaminated animals. Older patients are at increased risk of nervous system involvement in brucellosis. Brucella spp. can lead to central nervous system involvement through direct damage via invasion of neural tissue or indirect damage caused by endotoxins or immune inflammatory reactions elicited by the presence of the bacteria in the body. Patients can have general nonspecific symptoms in addition to neurological and psychiatric symptoms. There are 4 diagnostic criteria for the diagnosis of neurobrucellosis, which include signs and symptoms suggestive of neurobrucellosis, a positive finding of Brucella spp. in the cerebrospinal fluid (CSF), and/or a positive titer of antibodies targeting brucella in the CSF, lymphocytosis with high protein levels and low glucose levels in CSF, and imaging findings (either cranial magnetic resonance imaging or computed tomography) peculiar to neurobrucellosis. For the treatment, a combined therapy is favored over monotherapy for the eradication of Brucella. Moreover, a multirouted therapy has been associated with increased treatment efficacy. The prognosis of neurobrucellosis is dependent on patients' clinical presentation: brucellar meningitis is associated with a good prognosis, whereas diffuse central nervous system involvement is associated with the development of long-term sequelae. CONCLUSIONS: Neurobrucellosis affects patients globally and in endemic areas. Neurologists should familiarize themselves with its clinical presentation, diagnosis, and treatment to provide optimal care for their patients.

INTRODUCTION: We studied the trend of antimicrobial resistance and consumption at Saint George Hospital University Medical Center (SGHUMC), a tertiary care center in Beirut, Lebanon, with a focus on the SARS-CoV-2 pandemic. MATERIALS AND METHODS: We calculated the isolation density/1000 patient-days (PD) of the most isolated organisms from 1 January 2015-31 December 2020 that included: E. coli (Eco), K. pneumoniae (Kp), P. aeruginosa (Pae), A. baumannii (Ab), S. aureus (Sau), and E. faecium (Efm). We considered March-December 2020 a surrogate of COVID-19. We considered one culture/patient for each antimicrobial susceptibility and excluded Staphylococcus epidermidis, Staphylococcus coagulase-negative, and Corynebacterium species. We analyzed the trends of the overall isolates, the antimicrobial susceptibilities of blood isolates (BSI), difficult-to-treat (DTR) BSI, carbapenem-resistant Enterobacteriaceae (CRE) BSI, and restricted antimicrobial consumption as daily-defined-dose/1000 PD. DTR implies resistance to carbapenems, beta-lactams, fluoroquinolones, and additional antimicrobials where applicable. RESULTS AND DISCUSSION: After applying exclusion criteria, we analyzed 1614 blood cultures out of 8314 cultures. We isolated 85 species, most commonly Eco, at 52%. The isolation density of total BSI in 2020 decreased by 16%: 82 patients were spared from bacteremia, with 13 being DTR. The isolation density of CRE BSI/1000 PD decreased by 64% from 2019 to 2020, while VREfm BSI decreased by 34%. There was a significant decrease of 80% in Ab isolates (p-value < 0.0001). During COVID-19, restricted antimicrobial consumption decreased to 175 DDD/1000 PD (p-value < 0.0001). Total carbapenem consumption persistently decreased by 71.2% from 108DDD/1000 PD in 2015-2019 to 31 DDD/1000 PD in 2020. At SGHUMC, existing epidemics were not worsened by the pandemic. We attribute this to our unique and dynamic collaboration of antimicrobial stewardship, infection prevention and control, and infectious disease consultation.
RESUMO
BACKGROUND: Modified measles is rarely reported and thought to be an attenuated, less transmissible form of measles. The occupational safety and management of previously immunized healthcare providers (HCP) facing the global reemergence of measles is controversial and unclear.Aim: We report a measles outbreak with an unusual presentation among our vaccinated HCP at Saint George Hospital University Medical Center (SGHUMC) in Lebanon that occurred during a nationwide measles epidemic. METHODS: We recorded cases at SGHUMC, a 333-bed tertiary-care center, from April 2018 to June 2018. We established a measles clinic for investigating all febrile patients. HCP exposure was linked to influx of index cases through our Emergency Department. Modified measles was defined as any variation in the classic presentation with a pinpoint/vesicular rash, documented exposure and evidence of prior immunity. We performed serology testing to diagnose and/or document immunity and implemented outbreak controls measures including PPE, airborne isolation, and mass notification. FINDINGS: We diagnosed 8 inpatients with classic measles, and 9 affected HCP. We diagnosed 8 HCP with modified measles. One previously immunized HCP developed classic measles despite being immunized and having a positive IgG titer. Our contact tracing revealed a total of 96 exposed HCP with 27 HCP showing non-specific signs of viral illness. We required all the 9 affected HCP to undergo home isolation. CONCLUSION: We believe it is a top priority to achieve adequate measles immunity, especially among HCP that are at the frontline of healthcare systems. This necessitates revisiting vaccination schedules and achieving seroprotective titers to reclaim proper herd immunity.

BACKGROUND: Sexually transmitted infections (STIs) cause a major public health problem that affect both men and women in developing and developed countries. The aim of the study was to estimate the prevalence of 11 STIs among women who voluntarily participated in the study, while seeking gynecological checkup. The existence of an association between the presence of pathogens and symptoms and various sociodemographic risk factors was assessed. METHODS: A total of 505 vaginal and cervical specimens were collected from women above 18 years of age, with or without symptoms related to gynecological infections. Nucleic acid was extracted and samples were tested by real-time PCR for the following pathogens: Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Ureaplasma urealyticum, Urealplasma parvum, Trichomonas vaginalis, Mycoplasma hominis, Mycoplasma girerdii, Gardnerella vaginalis, Candida albicans and Human Papillomavirus (HPV). Positive HPV samples underwent genotyping using a microarray system. RESULTS: Of the 505 samples, 312 (62%) were screened positive for at least one pathogen. Of these, 36% were positive for Gardnerella vaginalis, 35% for Ureaplasma parvum, 8% for Candida albicans, 6.7% for HPV, 4.6% for Ureaplasma urealyticum, 3.6% for Mycoplasma hominis, 2% for Trichomonas vaginalis, 0.8% for Chlamydia trachomatis, 0.4% for Mycoplasma girerdii, 0.2% for Mycoplasma genitalium and 0.2% for Neisseria gonorrhoeae. Lack of symptoms was reported in 187 women (37%), among whom 61% were infected. Thirty-four samples were HPV positive, with 17 high risk HPV genotypes (HR-HPV); the highest rates being recorded for types 16 (38%), 18 (21%) and 51 (18%). Out of the 34 HPV positives, 29 participants had HR-HPV. Association with various risk factors were reported. CONCLUSIONS: This is the first study that presents data about the presence of STIs among women in Lebanon and the MENA region by simultaneous detection of 11 pathogens. In the absence of systematic STI surveillance in Lebanon, concurrent screening for HPV and PAP smear is warranted.

INTRODUCTION: Carbapenem resistant organisms (CRO) constitute a large group of bacteria with different mechanisms of resistance and recently increasing global incidence. This rise has ambiguous dynamics and essential local epidemiologic data is lacking. MATERIALS AND METHODS: In this retrospective study at the 400-bed Saint George Hospital (SGH) in Beirut, Lebanon, we retrieved electronic laboratory records of all intrinsic and acquired CRO isolates from January 1, 2010 until June 30, 2018. Isolation density was calculated as: number of isolates/1000PD. Analysis carried out using WHOnet with a trend time series analysis. RESULTS: During the study period, a total of 2150 non-duplicate CRO were isolated. While Acinetobacter baumanii (AB), Pseudomonas aeruginosa (CRPa), and Stenotrophomonas maltophilia (Sm) constituted 85% of total CRO in the study period, the carbapenem resistant enterobacteriaceae (CRE) rose from few sporadic cases before 2016 to a solid 32% of total CRO in 2018. Our most concrete trends were as follows. The rate of AB bacteremia was at an average of 0.114/1000 PD from 2011 to 2014. In 2015, a sudden doubling of AB bacteremia to 0.23/1000 PD. In 2017, there was a significant decrease to 0.113/1,000PD (p < 0.0001) to reach 0.097/1000PD in 2018 with a continuously declining trend. The peak of Sm bacteremia was in 2016 at 0.121/1000PD after which it significantly decreased by 21% in 2017 to disappear in 2018 (p < 0.0001). There were no significant trends observed in the isolation density of the CRPa group from 2010 until June 2018. Klebsiella pneumonia (CRKp) bacteremia was isolated first in 2013, then in 2016 and continued to rise (p = 0.028). In 2017, carbapenem resistant KP bacteremia rate doubled to 0.05/1,000PD from 0.024/1000 (p = 0.0139). CONCLUSION: In conclusion, this 9-year study at SGH depicts the major trends and dynamics of local CRO isolation, mainly A. baumanii, P. aeruginosa and CRKp. Further efforts are warranted both locally and internationally for a richer understanding of this trend. Bearing in mind that understanding antimicrobial resistance is a complex, multifaceted process that is only feasible when all its aspects are combined: molecular, phenotypic and clinical.

We decreased antimicrobial drug consumption in an intensive care unit in Lebanon by changing to colistin monotherapy for extensively drug-resistant Acinetobacter baumanii infections. We saw a 78% decrease of A. baumanii in sputum and near-elimination of blaoxa-23-carrying sequence type 2 clone over the 1-year study. Non-A. baumanii multidrug-resistant infections remained stable.

Extended-spectrum beta-lactamases (ESBL) and carbapenemase-producing organisms pose severe problems for hospitalized patients. In the absence of efficient sanitation and sewage disposal, the risks for transmission of hospital organisms into the community are high. Our objectives were to study the occurrence and mechanisms of resistance of multidrug-resistant gram-negative bacilli in two Lebanese hospital sewage treatment plants. Wastewater samples were collected, filtered, and cultivated on MacConckey+cefotaxime agars. ESBL, AmpC, metallo-ß-lactamases (MBL), and Klebsiella pneumoniae Carbapenemases (KPC) production were phenotypically detected using plain Mueller Hinton agar plates, and plates impregnated with 5 mM EDTA, 10 mg/mL phenyl boronic acid, and 250 µg/mL cloxacillin (embedded). Temocillin discs were used for the presumptive detection of OXAs. ESBL, carbapenemase, outer membrane protein F (OMPF), and outer membrane protein C (OMPC) genes were detected using polymerase chain reaction. Pulsed-field gel electrophoresis (PFGE) was performed to study the clonality of Enterobacter cloacae isolates. In total, 32 and 38 Enterobacteriaceae were detected from Hospital 1 and Hospital 2, respectively. All Escherichia coli and Klebsiella spp. isolates were ESBL producers. AmpC reached 25% and 28.9% of all isolates. Only one Enterobacter cloacae isolate from one hospital showed full resistance to carbapenems. Molecular tests, however, detected NDM-1 in two strains of Enterobacter cloacae. PFGE results showed 80% similarity between these two strains. The isolation of NDM-1-producing Enterobacter cloacae from hospital wastewater occurred almost a year before the first case of carbapenem-resistant Enterobacter spp. was detected from a patient sample in the laboratory hospital. Understanding the local epidemiology of resistance in hospitals should include areas of potential resistance, such as wastewater and hospital environment.

Infections caused by Acinetobacter baumannii (AB), an increasingly prevalent nosocomial pathogen, have been associated with high morbidity and mortality. We conducted this study to analyze the clinical features, outcomes, and factors influencing the survival of patients with AB bacteremia. We retrospectively examined the medical records of all patients developing AB bacteremia during their hospital stay at a tertiary care hospital in Beirut between 2010 and 2015. Ninety episodes of AB bacteremia were documented in eighty-five patients. Univariate analysis showed that prior exposure to high dose steroids, diabetes mellitus, mechanical ventilation, prior use of colistin and tigecycline, presence of septic shock, and critical care unit stay were associated with a poor outcome. High dose steroids and presence of septic shock were significant on multivariate analysis. Crude mortality rate was 63.5%. 70.3% of the deaths were attributed to the bacteremia. On acquisition, 39 patients had septicemia. Despite high index of suspicion and initiation of colistin and/or tigecycline in 18/39 patients, a grim outcome could not be averted and 37 patients died within 2.16 days. Seven patients had transient benign bacteremia; three of which were treated with removal of the line. The remaining four did not receive any antibiotics due to withdrawal of care and died within 26.25 days of acquiring the bacteremia, with no signs of persistent infection on follow up. A prolonged hospital stay is frequently associated with loss of functionality, and steroid and antibiotic exposure. These factors seem to impact the mortality of AB bacteremia, a disease with high mortality rate and limited therapeutic options.

Acute respiratory tract viral infections occur worldwide and are one of the major global burdens of diseases in children. The aim of this study was to determine the viral etiology of respiratory infections in hospitalized children, to understand the viral seasonality in a major Lebanese hospital, and to correlate disease severity and the presence of virus. Over a 1-year period, nasal and throat swabs were collected from 236 pediatric patients, aged 16-year old or less and hospitalized for acute respiratory illness. Samples collected were tested for the presence of 17 respiratory viruses using multiplex real-time RT-PCR. Pathogens were identified in 165 children (70%) and were frequently observed during fall and winter seasons. Co-infection was found in 37% of positive samples. The most frequently detected pathogens were human Rhinovirus (hRV, 23%), Respiratory Syncytial Virus (RSV, 19%), human Bocavirus (hBov, 15%), human Metapneumovirus (hMPV, 10%), and human Adenovirus (hAdV, 10%). A total of 48% of children were diagnosed with bronchiolitis and 25% with pneumonia. While bronchiolitis was often caused by RSV single virus infection and hAdV/hBoV coinfection, pneumonia was significantly associated with hBoV and HP1V1 infections. No significant correlation was observed between a single viral etiology infection and a specific clinical symptom. This study provides relevant facts on the circulatory pattern of respiratory viruses in Lebanon and the importance of using PCR as a useful tool for virus detection. Early diagnosis at the initial time of hospitalization may reduce the spread of the viruses in pediatric units. J. Med. Virol. 88:1874-1881, 2016. © 2016 Wiley Periodicals, Inc.

Primary or idiopathic retroperitoneal fibrosis, first described by Ormond in 1948, is a rare and elusive diagnosis, requiring a high level of suspicion. Patients usually present with entrapment of retroperitoneal organs, the most common being the ureters, causing hydronephrosis and acute kidney injury. Here, we present the case of a 56-year-old male presenting for recurrent and intermittent scrotal edema. Upon routine laboratory workup, he was found to have an elevated creatinine level. Imaging showed encasement of bilateral ureters. Bilateral ureteral stents were placed with relief of his obstructive uropathy, followed by normalization of creatinine. The patient later underwent laparoscopic release of retroperitoneal adhesions. Biopsies taken from the operative site showed fibroblast proliferation and elements of acute and chronic inflammation. With further workup of etiologies being negative, he was diagnosed with idiopathic retroperitoneal fibrosis.

INTRODUCTION: In March 2009, a new influenza virus strain emerged, currently known as the 2009 pandemic H1N1 virus. The virus first appeared in Mexico and rapidly spread globally to reach a pandemic level in June of the same year. We describe here the experience of one major referral center in Beirut, Lebanon. MATERIALS AND METHODS: The laboratory department at St. George Hospital University Medical Center received respiratory specimens from hospital wards, the emergency department, in addition to a considerable proportion collected directly from "outpatients" in the lab. We used the real time RT-PCR as our main diagnostic test. We collected data about the patients from the laboratory information system and from the hospital medical records department. RESULTS: From mid-August 2009 till the end of January 2010, a total of 1771 specimens were analyzed, with 948 (53.5%) returning positive for influenza A (H1N1) by RT-PCR. Only 79 patients with H1N1 infection required hospitalization. Most of H1N1 confirmed patients were children and adolescents aged 5 to 17 years and young adults between 25 and 44 years. The most common symptoms at presentation were: fever, cough, shortness of breath, chills, rhinorrhea or nasal congestion, as well as gastrointestinal symptoms. Twenty-three patients required ICU care and eight patients died. The vast majority had an uncomplicated course of illness and was managed in an outpatient setting. CONCLUSION: The percentage of positive tests during the pandemia was significantly elevated, although few patients experienced drastic clinical outcomes.

The purpose of this study was to investigate the bacterial etiology of urinary tract infections in one of the busiest hospitals of Lebanon and to examine the epidemiologic and microbiologic properties of Escherichia coli isolated from urinary tract infections of Lebanese patients over a 10-year period. Methods. This retrospective study analyzed the data generated between 2000 and 2009 (10,013 Gram-positive and Gram-negative bacteria). Bacterial identification was based on standard culture and biochemical characteristics of isolates. Antimicrobial susceptibility was tested by the disk diffusion method, and ESBL production was detected by synergy with third-generation cephalosporins and amoxiclav. Results. E. coli was the most frequent isolate throughout the ten years (60.64% of the total isolates). It was followed by Klebsiella pneumoniae and Proteus sp., Pseudomonas aeruginosa, Enterococcus sp., and Streptococcus agalactiae. E. coli occurred more frequently in women (69.8%) than in men (61.4%). The lowest percentage of susceptibility of E. coli was manifested against piperacillin and ampicillin. An increase in the production of ESBL was observed (2.3% in 2000 to 16.8% in 2009). Conclusions. The etiology of urinary tract infections and their susceptibility profiles are important to be evaluated in countries like Lebanon where a severe misuse of antibiotics at all levels is observed.
RESUMO
A case of severe thrombocytopenic purpura as the sole manifestation of brucellosis in an eight-year-old boy is presented. Clinical examination revealed mucosal hemorrhages and splenomegaly. The initial diagnosis was immune thrombocytopenic purpura (ITP) and he received intravenous gamma globulins and steroids with good hematologic and clinical response. His brucella agglutination titer was positive and he received treatment with intravenous gentamicin and oral co-trimoxazole with good response. Although mild hematologic manifestations can be encountered in brucellosis, severe thrombocytopenia is rare. Prompt recognition of this association is essential for early therapy. A brief review of thrombo-cytopenic purpura associated with brucellosis is presented.

We investigated the basis of the carbapenem resistance of 17 multidrug-resistant Acinetobacter baumannii clinical isolates collected from 2004 to 2005 at the Saint George University Hospital in Beirut, Lebanon. A. baumannii isolates were clonally related and were susceptible to colistin and trimethoprim-sulfamethoxazole, susceptible or intermediate to ampicillin-sulbactam and meropenem, and resistant to all other antimicrobials. Conjugation experiments demonstrated that resistance to imipenem could be transferred along with a plasmid containing the carbapenem-hydrolyzing oxacillinase bla(OXA-58) gene. The plasmid that we called pABIR was 29,823 bp in size and showed a novel mosaic structure composed of two origins of replication, four insertion sequence (IS) elements, and 28 open reading frames. The bla(OXA-58) gene was flanked by IS18 and ISAba3 elements at the 5' and 3' ends, respectively. The production of the carbapenem-hydrolyzing oxacillinase OXA-58 was apparently the only mechanism for carbapenem resistance in A. baumannii isolates causing the outbreak at the Lebanese Hospital.

BACKGROUND: The international migration of physicians is a global public health problem. Lebanon is a source country with the highest emigration factor in the Middle East and North Africa and the 7th highest in the World. Given that residency training abroad is a critical step in the migration of physicians, the objective of this study was to survey students of Lebanese medical schools about their intentions to train abroad and their post training plans. METHODS: Our target population consisted of all students of Lebanese medical schools in the pre-final and final years of medical school. We developed the survey questionnaire based on the results of a qualitative study assessing the intentions and motives for students of Lebanese medical schools to train abroad. The questionnaire inquired about student's demographic and educational characteristics, intention to train abroad, the chosen country of abroad training, and post-training intention of returning to Lebanon. RESULTS: Of 576 eligible students, 425 participated (73.8% response rate). 406 (95.5%) respondents intended to travel abroad either for specialty training (330 (77.6%)) or subspecialty training (76 (17.9%)). Intention to train abroad was associated with being single compared with being married. The top 4 destination countries were the US (301(74.1%)), France (49 (12.1%)), the United Kingdom (31 (7.6%)) and Canada (17 (4.2%)). One hundred and two (25.1%) respondents intended to return to Lebanon directly after finishing training abroad; 259 (63.8%) intended to return to Lebanon after working abroad temporarily for a varying number or years; 43 (10.6%) intended to never return to Lebanon. The intention to stay indefinitely abroad was associated male sex and having a 2nd citizenship. It was inversely associated with being a student of one of the French affiliated medical schools and a plan to train in a surgical specialty. CONCLUSION: An alarming percentage of students of Lebanese medical schools intend to migrate for post graduate training, mainly to the US. A minority intends to return directly to Lebanon after finishing training abroad.

BACKGROUND: Invasive aspergillosis (IA) is a major cause of morbidity and mortality in patients with hematologic malignancy (HM). There are 2 lipid formulations of amphotericin B (AMB) currently in widespread use: AMB lipid complex (ABLC) and liposomal AMB (L-AMB). There are limited data comparing the efficacy and safety of these 2 agents in the treatment of IA in patients with cancer. METHODS: The authors retrospectively studied 381 consecutive patients with HM who had proven or probable IA (according to European Organization for Research and Treatment of Cancer/Mycosis Study Group of the National Institute of Allergy and Infectious Diseases criteria) between June 1993 and December 2005. Of these patients, 158 received primary antifungal therapy with either L-AMB (n=106) or ABLC (n=52). The number of salvage antifungal regimens given were 51 L-AMB regimens and 30 ABLC regimens. It should be noted that the population described in this report was not typical of the hematologic cancer population with IA because of the advanced stage and the severity of the underlying diseases. RESULTS: Risk factors for IA, such as underlying malignancy, neutropenia, steroid use, admission to an intensive care unit, and the presence of graft-versus-host disease, were comparable among the study drug group in the primary or salvage setting. Likewise, comparable distribution of types of Aspergillus species and the presence of disseminated IA were observed. Response to primary or salvage therapy was equally poor in both drug study groups regardless of treatment modality (range, 7.7-15.8% response). In the primary therapy group, ABLC was associated with significantly higher nephrotoxicity than L-AMB (P<.001). CONCLUSIONS: Among patients with HM, primary therapy and salvage therapy for IA with either ABLC or L-AMB as single agent were associated equally with poor outcome. L-AMB appeared to be less nephrotoxic in the primary therapy setting.

In the context of a worldwide physician brain drain phenomenon, Lebanon has the highest emigration factor in the Middle East and North Africa. In this manuscript we aim to identify and develop a conceptual framework for the factors underlying the decisions of graduating Lebanese medical students to train abroad. We conducted two focus groups and seven semi-structured individual interviews with 23 students. In the deductive analysis (based on the push-pull theory), students reported push factors in Lebanon and pull factors abroad related to five dimensions. They focused predominantly on how training abroad provides them with a competitive advantage in an oversaturated Lebanese job market. An inductive analysis revealed the following emerging concepts: repel factors abroad and retain factors locally; societal expectations that students should train abroad; marketing of abroad training; and an established culture of migration. The marketing of abroad training and the culture of migration are prevalent in the academic institutions.
