RESUMO

Objective: To determine whether adding urine culture to urinary tract infection diagnosis in pregnant women from refugee camps in Lebanon reduced unnecessary antibiotic use. Methods: We conducted a prospective, cross-sectional study between April and June 2022 involving pregnant women attending a Médecins Sans Frontières sexual reproductive health clinic in south Beirut. Women with two positive urine dipstick tests (i.e. a suspected urinary tract infection) provided urine samples for culture. Bacterial identification and antimicrobial sensitivity testing were conducted following European Committee on Antimicrobial Susceptibility Testing guidelines. We compared the characteristics of women with positive and negative urine culture findings and we calculated the proportion of antibiotics overprescribed or inappropriately used. We also estimated the cost of adding urine culture to the diagnostic algorithm. Findings: The study included 449 pregnant women with suspected urinary tract infections: 18.0% (81/449) had positive urine culture findings. If antibiotics were administered following urine dipstick results alone, 368 women would have received antibiotics unnecessarily: an overprescription rate of 82% (368/449). If administration was based on urine culture findings plus urinary tract infection symptoms, 144 of 368 women with negative urine culture findings would have received antibiotics unnecessarily: an overprescription rate of 39.1% (144/368). The additional cost of urine culture was 0.48 euros per woman. Conclusion: A high proportion of pregnant women with suspected urinary tract infections from refugee camps unnecessarily received antibiotics. Including urine culture in diagnosis, which is affordable in Lebanon, would greatly reduce antibiotic overprescription. Similar approaches could be adopted in other regions where microbiology laboratories are accessible.

RESUMO

BACKGROUND: The Lebanese American University has a well-functioning inter-professional education (IPE) programme; this is a fundamental pedagogical approach in healthcare education in which students from different professions learn together, ultimately leading to improving the skills of the health care workforce and thus improving patient outcomes. The programme includes nursing, nutrition, medicine, pharmacy and social work students, and has now been running for 6 years. AIMS: This paper aims at describing the implementation of an IPE programme in Lebanon by focusing on how to overcome the main challenges. METHODS: We describe our experience using the categories of challenges developed by Sunguya et al. (2014), where they analysed published reports of IPE programmes in developed countries. We identified three additional challenges that might be relevant throughout the Middle East/North Africa (MENA) region or in countries with similar socioeconomic characteristics. RESULTS: The challenges encountered in designing and implementing the IPE programme were similar to other programmes: curriculum, leadership, resources, stereotypes and attitudes, variety of students, IPE concept, teaching, enthusiasm, professional jargon and accreditation as well as assessment of learning, security and logistics. CONCLUSIONS: This paper provides data and successful strategies that can be used by planned or implemented programmes in similar socioeconomic contexts in the MENA region.

RESUMO

The Lebanese American University Interprofessional Education (LAU IPE) Steps Framework consists of a five-step workshop-based series that is offered throughout the curriculum of health and social care students at an American university in Lebanon. The aim of the present study was to report students' perceptions of their readiness for interprofessional learning before and after completing the IPE steps, their evaluations of interprofessional learning outcomes, as well as their satisfaction with the learning experience as a whole. A longitudinal survey design was used: questionnaires were completed by students before IPE exposure and after each step. The results showed that before IPE exposure, students' perceptions of their readiness for interprofessional learning were generally favourable, with differences across genders (stronger professional identity in females compared to males) and across professions (higher teamwork and collaboration in pharmacy and nutrition students compared to other professions and lower patient centredness in nursing students compared to others). After participation in the IPE steps, students showed enhanced readiness for interprofessional learning and differences between genders and professions decreased. Participants were satisfied with the learning experience and assessment scores showed that all IPE learning outcomes were met. The LAU IPE Steps Framework may be of value to other interprofessional education course developers.

RESUMO

Background: There are conflicting reports of the interaction between COVID-19 and HIV infection among coinfected individuals, and there is a particular dearth of evidence among populations in the Middle East. Aim: To determine if living with HIV and use of antiretroviral therapy increases susceptibility to, and severity of, COVID-19. Methods: This cross-sectional study was based on telephone survey of COVID-19 symptoms duration and clinical course among 200 people living with HIV (PLWHs) and a review of medical records in Beirut, Lebanon, during Spring 2021. Data were collected from consenting patients using standardized forms. The laboratory and medical characteristics of PLWHs with and without COVID-19 were compared and the outcomes of COVID-19 were described. A binary logistic regression model for contracting COVID-19 was constructed based on clinically relevant covariates consistently associated with COVID-19. Significance level was set at 0.05 and statistical analysis was performed using SPSS version 27.0. The Lebanese American University Institutional Review Board approved the study protocol. Results: Fifty-two of 200 PLWHs contracted COVID-19 but only 4 progressed to severe COVID-19. No significant differences were found with respect to gender, time since HIV diagnosis, most recent CD4 count, viral load, substance use, comorbidities, or use of antiretroviral therapy. Older PLWHs were at lower risk of contracting COVID-19; COVID-19 infection was significantly associated with younger age. Conclusions: COVID-19 infection was associated with younger age among PLWHs in Lebanon, possibly due to behavioural and socioeconomic factors.

RESUMO

BACKGROUND: A number of cutaneous manifestations and adverse cutaneous reactions have been associated with COVID-19 infection and vaccine. OBJECTIVES: A Lebanese national registry was established to characterize the dermatologic manifestations and adverse cutaneous reactions associated with COVID-19 infection and vaccination in a sample of the Lebanese population. METHODS: An observational cross-sectional study was conducted via a web-based clinical form distributed to physicians wishing to report their cases from May 2021 till May 2022. RESULTS: In total, 142 patients were entered in the registry, of which 133 were adults and nine were pediatric patients. The main dermatological manifestations reported with COVID-19 infection in the adult group were urticaria (32.9%), telogen effluvium (21.4%), morbilliform (10%), and papulosquamous (8.6%) eruptions. Urticaria was the most common adverse cutaneous reaction to the vaccine (33%). Interestingly, herpes zoster was triggered in 12 patients post vaccination in our series with this finding more frequently seen in patients above the age of 41 (P = 0.013). In the pediatric group, the most reported dermatological findings associated with COVID-19 infection were malar erythema (25%) and telogen effluvium (25%). One 16-year-old patient developed lichen planus after one dose of a COVID-19 vaccine. No deaths were reported in both age groups. CONCLUSION: This Lebanese registry adds more robust evidence that clinical manifestations of the COVID-19 virus and vaccine are diverse. More studies are necessary to establish the pathophysiology of these dermatological findings in the context of COVID-19 infection and vaccination.

RESUMO

This study aims to describe COVID-19 patients characteristics, laboratory and imaging results, and the different outcomes of patients admitted to the Lebanese American University Medical Center-Rizk Hospital over a period of 9 months. In this observational retrospective study, data were obtained from electronic medical records of 491 male and female patients from the ages of 17 to 97. Analysis of the patients was performed in 3 periods: August 2020 to October 20 November 202020 to January 2021 and February 2021 to April 2021 corresponding with 3 waves of newly diagnosed cases during this period. The sample showed a male predominance with an average age of 63. The average hospitalization length was 10.1 days. The majority of patients were discharged to quarantine. The distribution of hospitalized cases was significantly correlated to the monthly distribution of newly COVID-19 cases in Lebanon. There was no significant difference in patient's characteristics between the 3 periods of the study (gender, age, body mass index, smoking, and medical conditions). Clinical presentations of the patients varied between the 3 periods. Similarly, the course and outcome of infection varied. Patients received less oxygen during period 1, while more patients were cured during period 3. This study presents the first Lebanese cohort of COVID-19 patients with their medical background, clinical presentation, laboratory results, radiological findings and course of infection with its outcome. It also shows how the relations between the medical manifestation of the COVID-19 pandemic and the socio-political measures of infection control are deeply intertwined.

RESUMO

Cryptococcal meningitis is an opportunistic infection associated with altered immunity. Immunomodulatory agent use in severe coronavirus disease 2019 (COVID-19) may predispose such infections. Here, we present a 75-year-old male patient who presented with fever and altered general status after severe COVID-19 infection and developed cryptococcal meningitis. Opportunistic infection may arise from the use of immunomodulation in severe COVID-19, especially in the elderly population. This article describes the case and extensively reviews cryptococcal disease post-COVID-19 literature, highlighting the risk from immunosuppressive treatment.

RESUMO

Regimens for managing thromboembolic complications of COVID-19 are still not very well established. The present study compares the clinical characteristics and outcomes of patients hospitalized with COVID-19 receiving different anticoagulation regimens with and without aspirin. This is a retrospective observational study of 491 patients hospitalized for COVID-19 from August 2020 to April 2021. Data regarding clinical characteristics, laboratory findings, and outcomes of patients receiving different anticoagulation with and without aspirin regimens was collected, according to which 5 patient groups were defined: received no anticoagulation (NAA), prophylactic anticoagulation with (PA) or without aspirin (PAA) and therapeutic anticoagulation with (TA) or without aspirin (TAA). The average age was highest in the TAA group. Desaturation was highest in the TA and TAA groups. Diabetes, hypertension, dyslipidemia and coronary artery disease were the most prevalent in aspirin groups (PAA and TAA) as was heart failure in the TA and TAA groups and cancer in the TA and PAA groups. Elevated troponin was observed in the PAA and TAA groups. TA and TAA patients received oxygen therapy, needed ICU admission overall, and required invasive ventilation and vasopressors the most. Prophylactic anticoagulation groups (PA and PAA) had the highest patient survival rates. Patients with severe COVID-19 infections were more likely to receive higher, therapeutic, anticoagulation doses. Aspirin was given to patients with preexisting comorbidities, but it had no statistically significant impact on the outcomes of the different groups. Groups receiving prophylactic anticoagulation had the best survival outcomes.

RESUMO

BACKGROUND: COVID-19 infection in patients with type 2 diabetes mellitus (T2DM) -a chronic illness in Lebanon-is not well described. METHODS: This was a single-centre retrospective observational study of 491 patients, including 152 patients with T2DM, who were hospitalised for COVID-19 between 20 August 2020 and 21 April 2021. Data on clinical characteristics, laboratory and radiological findings and outcomes were collected from the electronic medical records. Clinical characteristics and in-hospital mortality between patients with and without T2DM infected with COVID-19 using multivariate analysis were compared. RESULTS: Patients with T2DM were significantly older than those without T2DM (mean age, 68.7 vs. 60.3 years). Patients with T2DM were more likely to present with a body temperature of <38.3°C (83.9% vs. 69.9%) and less likely to present with chest pain (3.9% vs. 9.1%) and sore throat (2.0% vs. 6.8%). Patients with T2DM were more likely to be hypertensive (76.35% vs. 41%) and dyslipidaemic (58.6% vs. 25.7%) and had more frequent underlying coronary artery disease (33.6% vs. 12.4%). The rates of patients with creatinine levels of ≥1.17 mg/L and troponin T levels of ≥4 ng/dL were higher in the T2DM group than in the non-T2DM group (30.4% vs. 15% and 93.3% vs. 83.1%, respectively). Patients with T2DM were more likely to be admitted to the intensive care unit (ICU) (34.2% vs. 22.1%), require invasive ventilation (18.4% vs. 10.3%) and receive vasopressors (16.4% vs. 10.0%). Increasing age and the use of invasive ventilation and vasopressors were associated with higher odds of mortality (odds ratio (OR), 1.08, 9.95 and 19.83, respectively), whereas longer ICU stay was associated with lower odds of mortality (OR, 0.38). The odds of mortality were lower in the T2DM group than in the non-T2DM group (OR, 0.27). CONCLUSION: Among patients hospitalised for COVID-19, those with T2DM were older, presented with milder symptoms and had more comorbidities and higher troponin T levels compared with those without T2DM. Despite the worse clinical course, the patients with T2DM had lower odds of mortality than those without T2DM.

RESUMO

INTRODUCTION: There is lack of universal agreement on the management of COVID-19. Intravenous high dose vitamin C (HDVC), remdesivir (RDV), and favipiravir (FPV) have been suggested as part of the treatment regimens and only RDV is approved by the Food and Drug Administration (FDA) so far. There is no study in Lebanon that addresses the descriptive cohort of HDVC and antiviral therapy amongst COVID-19 inpatients. Our goal was to highlight such a cohort. METHODOLOGY: A retrospective electronic chart review of COVID-19 inpatients was done over a period of 10 months (August 2020 to April 2021). Comparative data analysis was performed between HDVC and non-HDVC (NHDVC) groups, and RDV and FPV groups. RESULTS: Among HDVC patients, 70.1% (p = 0.035) and 67.2% (p = 0.008) had dyspnea and desaturation respectively. Patients on HDVC were less likely to remain in hospital for more than 20 days (p = 0.003). HDVC patients were more likely to be on oxygen therapy with 74.7% (p = 0.002). RDV patients were more likely to be on other COVID-19-related medications during hospitalization including the use of tofacitinib, baricitinib, tocilizumab, and anticoagulation as recommended in the guidelines. Statistical significance was noted for the status on discharge as 90.1% of the patients that received RDV were discharged after clinical improvement, compared to the 74.2% of the FPV patients. CONCLUSIONS: Further research is needed to establish local guidelines for the treatment of COVID-19. A significant role of HDVC and FPV might resurface if randomized control trials are conducted.

RESUMO

The Food and Drug Administration (FDA) approved the first SARS-CoV-2 mRNA vaccine (Pfizer-BioNTech) in December 2020. New adverse events have emerged since these vaccines have reached market. Although no clear association between messenger ribonucleic acid (mRNA) vaccines and autoimmunity has emerged, the significance of such an association warrants further exploration. After obtaining consent, a standardized survey on baseline characteristics and other relevant variables was conducted on unvaccinated individuals who were scheduled for vaccination and had not previously contracted COVID-19. Blood samples were collected from participants prior to the first dose, prior to the second dose, and 1 month after the second dose. All collected samples were tested for antinuclear antibody (ANA) titers using indirect immunofluorescence microscopy kits, and antiphospholipid (APS) immunoglobulin M (IgM) and immunoglobulin G (IgG) levels using an enzyme-linked immunoassay (ELISA) technique. ANA titers were positive for 9 participants out of 101 (8.9%) in the first pre-vaccination draw. For the second draw, the number of participants testing positive for ANA decreased to 5 (5%). For the last draw, 6 (5.9%) participants tested positive for ANA titers. One participant tested positive for APS IgM at the first pre-vaccination draw, 2 tested positive at the second draw, and 2 at the third draw. As for APS IgG titers, all participants tested negative in the three draws. McNemar's test for two dependent categorical outcomes was conducted on all variables and did not show a statistical significance. The McNemar test of these two composite variables (i.e., ANA/APS, first draw vs. ANA/APS, second and third draws) did not show statistical significance. The 2-sided exact significance of the McNemar test was 1.0. The Friedman test also showed no significance (p = 0.459). No association was found between BNT162b2 vaccine administration and changes in APS and ANA titers. The benefits of the BNT162b2 vaccine significantly outweigh any possible risk of autoimmune dysregulation considering the current evidence.

RESUMO

OBJECTIVES: Community-acquired respiratory infections (CARTIs) are responsible for serious morbidities worldwide. Identifying the aetiology can decrease the use of unnecessary antimicrobial therapy. In this study, we intend to determine the pathogenic agents responsible for respiratory infections in patients presenting to the emergency department of several Lebanese hospitals. METHODS: A total of 100 patients presenting to the emergency departments of four Lebanese hospitals and identified as having CARTIs between September 2017 and September 2018 were recruited. Specimens of upper and lower respiratory tract samples were collected. Pathogens were detected by a multiplex polymerase chain reaction respiratory panel. RESULTS: Of 100 specimens, 84 contained at least one pathogen. Many patients were detected with ≥2 pathogens. The total number of pathogens from these 84 patients was 163. Of these pathogens, 36 (22%) were human rhinovirus, 28 (17%) were Streptococcus pneumoniae, 16 (10%) were metapneumovirus, 16 (10%) were influenza A virus, and other pathogens were detected with lower percentages. As expected, the highest occurrence of pathogens was observed between December and March. Respiratory syncytial virus accounted for 2% of the cases and only correlated to paediatric patients. CONCLUSION: CARTI epidemiology is important and understudied in Lebanon. This study offers the first Lebanese data about CARTI pathogens. Viruses were the most common aetiologies of CARTIs. Thus, a different approach must be used for the empirical management of CARTI. Rapid testing might be useful in identifying patients who need antibiotic therapy.

RESUMO

Objectives: The World Health Organization has promoted the use of serological testing as a rapid and accurate technique for the detection of immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In Lebanon, a better understanding of the immune response against SARS-CoV-2 is needed to develop effective measures for prevention and to plan an appropriate national vaccination program. This study aimed to measure the immunity status in Lebanon. Methods: In this cross-sectional study, the population comprised male and female Lebanese and non-Lebanese residents of Lebanon between the ages 15 and 75. The exclusion criteria included: same household, symptomatic individuals, and extremes of age (< 15 and > 75). Representative testing for SARS-CoV-2 antibodies (anti-SARS-CoV-2 electrochemiluminescence immunoassay/ECLIA) was used to assess the prevalence of SARS-CoV-2 infection in Lebanon. Results: In total, 13 755 participants were recruited over a 6-month period. Of these, 3168 (23.03%) individuals tested positive for anti-SARS-CoV-2, with levels of positivity varying among districts. A higher level of seropositivity was detected in the female participants. Conclusion: Seroprevalence against SARS-CoV-2 varied within Lebanon, but was comparable to the levels reported in the MENA region at the time of the study. The seroprevalence documented in this study represents a level of immunity that is not protective at the national level. Funding: This study was funded by the Lebanese American University School of Medicine.

RESUMO

The main mechanism of imipenem resistance in Pseudomonas aeruginosa is via downregulation of the gene for OprD porin. In a previous study, it was shown that the level of resistance did not parallel with the degree of downregulation of the porin gene, thus arguing for the existence of other resistance mechanisms. Penicillin-binding protein (PBP) 2 and PBP3 are involved in carbapenem resistance in Escherichia coli. The genes for PBPs were sequenced in three imipenem-resistant clinical strains and these strains were conjugated with two susceptible P. aeruginosa PA0 strains, selecting for auxotrophic markers. In all the clinical and resistant isolates there was no obvious elevation of AmpC cephalosporinase. The active sites of PBP1b (ponB), PBP2 (pbpA), PBP3 (pbpB) and PBP6 (dacC) had no mutations in any of the examined strains. Production of oprD mRNA was significantly lower in clinical strains and transconjugants after selection for the proB marker (PA4565 at 5113kb). The clinical strains had alterations in OprD that were not found in transconjugants. Our findings suggest that PBPs do not play a role in imipenem resistance in the clinical strains examined here, but that a regulatory gene for oprD contributing to carbapenem resistance is located close to the proB gene.

RESUMO

INTRODUCTION: Approximately 80% of diabetes-related lower extremity amputations are preceded by a foot ulcer. Global studies on the epidemiology of diabetic foot ulcer (DFU) infections and guidelines detailing the most common pathogens and their respective antimicrobial susceptibilities are available. While Gram-positive cocci, mainly Staphylococcus species (spp.), were the most common organisms cultured from DFU in the United States, the Gram-negative Pseudomonas spp. were found to be the most common in some Middle Eastern countries. In Lebanon, however, such studies remain scarce. This study, conducted in Lebanon, investigated the most common organisms in DFU infections and their antimicrobial profiles. METHODOLOGY: We collected data from all documented diabetic foot infections between January 2015 and March 2016, 128 participants total, from 5 different hospitals in various regions of Lebanon. RESULTS: Among all isolates, Enterobacteriaceae (42%), Pseudomonas spp. (18.6%) and methicillin-sensitive Staphylococcus aureus (MSSA) (15.3%) were the most frequent bacteria. In addition, 72% of Pseudomonas spp. were susceptible to ciprofloxacin and 63.6% of Enterobacteriaceae were susceptible to either amoxicillin/clavulanate or ciprofloxacin, 91% were susceptible to piperacillin/tazobactam. Methicillin-resistant Staphylococcus aureus (MRSA) was only found in hospitalized patients or those who received prior antibiotics. Polymicrobial infections were documented in only 38% of patients. CONCLUSION: In Lebanon, the most appropriate empirical oral outpatient treatment would be a combination of amoxicillin/clavulanate and ciprofloxacin. As for admitted patients who have failed the oral regimen, piperacillin/tazobactam would then be the treatment of choice.

RESUMO

AIM: Extended-spectrum ß-lactamase-producing (ESBL) Escherichia coli are a public threat worldwide. This study aimed at analyzing the genomic and functional attributes of nine ESBLs taken from rectal swabs. MATERIALS & METHODS: Samples were isolated from patients admitted for gastrointestinal and urological procedures at the University Medical Center-Rizk Hospital (UMCRH) in Lebanon. Illumina paired-end libraries were prepared and sequenced. RESULTS: The isolates were distributed into five lineages: ST131, ST648, ST405, ST73 and ST38, and harbored bla OXA-1, bla TEM-1B, bla TEM-1C and aac(6')Ib-cr. ST131 isolates were carriers of stx2 converting I phage. CONCLUSION: This is the first comprehensive genomic analysis performed on ESBLs in Lebanon.

RESUMO

OBJECTIVE: The emergence of extended-spectrum ß-lactamase (ESBL)-producing bacteria is now a critical concern. The ESBL-producing Klebsiella pneumoniae constitutes one of the most common multidrug-resistant (MDR) groups of gram-negative bacteria involved in nosocomial infections worldwide. In this study we report on the molecular characterization through whole genome sequencing of an ESBL-producing K. pneumoniae strain, LAU-KP1, isolated from a stool sample from a patient admitted for a gastrointestinal procedure/surgery at the Lebanese Amrican University Medical Center-Rizk Hospital (LAUMCRH) in Lebanon. METHODS: Illumina paired-end libraries were prepared and sequenced, which resulted in 4,220,969 high-quality reads. All sequence processing and assembly were performed using the A5 assembly pipeline. RESULTS: The initial assembly produced 86 contigs, for which no scaffolding was obtained. The final collection of contigs was submitted to GenBank. The final draft genome sequence consists of a combined 5,632,663 bases with 57% G+C content. Automated annotation was performed using the RAST annotation server. Sequencing analysis revealed that the isolate harbored different ß-lactamase genes, including bla oxa-1, bla CTX-M-15, bla SHV-11, and bla TEM-1b. The isolate was also characterized by the concomitant presence of other resistance determinants most notably acc(6')-lb-cr and qnrb1. The entire plasmid content was also investigated and revealed homology with four major plasmids pKPN-IT, pBS512_2, pRSF1010_SL1344, and pKPN3. CONCLUSIONS: The potential role of K. pneumonia as a reservoir for ESBL genes and other resistance determinants is along with the presence of key factors that favor the spread of antimicrobial resistance a clear cause of concern and the problem that Carbapenem-non-susceptible ESBL isolates are posing in hospitals should be reconsidered through systematic exploration and molecular characterization.
