RESUMEN

OBJECTIVES: To evaluate the safety and efficacy of switching from intravenous (IV) to oral antimicrobial therapy in patients with Enterobacterales bacteraemia, after completion of 3-5 days of microbiologically active IV therapy. METHODS: A multicentre, open-label, randomized trial of adults with monomicrobial Enterobacterales bacteraemia caused by a strain susceptible to ≥1 oral beta-lactam, quinolone, or trimethoprim/sulfamethoxazole. Inclusion criteria included completion of 3-5 days of microbiologically active IV therapy, being afebrile and haemodynamically stable for ≥48 hours, and absence of an uncontrolled source of infection. Pregnancy, endocarditis, and neurological infections were exclusion criteria. Randomization, stratified by urinary source of bacteraemia, was to continue IV (IV Group) or to switch to oral therapy (Oral Group). Agents and duration of therapy were determined by the treating physicians. The primary endpoint was treatment failure, defined as death, need for additional antimicrobial therapy, microbiological relapse, or infection-related re-admission within 90 days. Non-inferiority threshold was set at 10% in the 95% CI for the difference in the proportion with treatment failure between the Oral and IV Groups in the modified intention-to-treat population. The protocol was registered at ClinicalTrials.gov (NCT04146922). RESULTS: In the modified intention-to-treat population, treatment failure occurred in 21 of 82 (25.6%) in the IV Group, and 18 of 83 (21.7%) in the Oral Group (risk difference -3.7%, 95% CI -16.6% to 9.2%). The proportions of subjects with any adverse events (AE), serious AE, or AE leading to treatment discontinuation were comparable. DISCUSSION: In patients with Enterobacterales bacteraemia, oral switch, after initial IV antimicrobial therapy, clinical stability, and source control, is non-inferior to continuing IV therapy.

RESUMEN

We retrospectively investigated the clinical outcomes of favipiravir in patients with COVID-19 pneumonia. Patients who between 23 May 2020 and 18 July 2020 received ≥ 24 h of favipiravir were assigned to the favipiravir group, while those who did not formed the non-favipiravir group. The primary outcome was 28-day clinical improvement, defined as two-category improvement from baseline on an 8-point ordinal scale. Propensity scores (PS) for favipiravir therapy were used for 1:1 matching. The unmatched cohort included 1493 patients, of which 51.7% were in the favipiravir group, and 48.3% were not receiving supplemental oxygen at baseline. Significant baseline differences between the two unmatched groups existed, but not between the PS-matched groups (N = 774). After PS-matching, there were no significant differences between the two groups in the proportion with 28-day clinical improvement (93.3% versus 92.8%, P 0.780), or 28-day all-cause mortality (2.1% versus 3.1%, P 0.360). Favipiravir was associated with more viral clearance by day 28 (79.8% versus 64.1%, P < 0.001). Adverse events were common in both groups, but the 93.9% were Grades 1-3. Favipiravir therapy for COVID-19 pneumonia is well tolerated but is not associated with an increased likelihood of clinical improvement or reduced all-cause mortality by 28 days.

RESUMEN

BACKGROUND: Clinical data on Coronavirus Disease 2019 (COVID-19) in solid organ transplant (SOT) recipients are limited. We herein report the initial clinical experience with COVID-19 in SOT recipients in Qatar. METHODS: All SOT recipients with laboratory-confirmed COVID-19 up to May 23, 2020 were included. Demographic and clinical data were extracted retrospectively from the hospital's electronic health records. Categorical data are presented as frequency and percentages, while continuous variables are summarized as medians and ranges. RESULTS: Twenty-four SOT recipients with COVID-19 were identified (kidney 16, liver 6, heart 1, and liver and kidney 1). Organ transplantation preceded COVID-19 by a median of 60 months (range 1.7-184). The median age was 57 years (range 24-72), and 9 (37.5%) transplant recipients were females. Five (21%) asymptomatic patients were diagnosed through proactive screening. For the rest, fever (15/19) and cough (13/19) were the most frequent presenting symptoms. Five (20.8%) patients required invasive mechanical ventilation in the intensive care unit (ICU). Eleven (46%) patients developed acute kidney injury, including three in association with drug-drug interactions involving investigational COVID-19 therapies. Maintenance immunosuppressive therapy was modified in 18 (75%) patients, but systemic corticosteroids were not discontinued in any. After a median follow-up of 226 days (26-272), 20 (83.3%) patients had been discharged home, 2 (8.3%) were still hospitalized, 1 (4.2%) was still in the ICU, and 1 (4.2%) had died. CONCLUSIONS: Our results suggest that asymptomatic COVID-19 is possible in SOT recipients and that overall outcomes are not uniformly worse than those in the general population. The results require confirmation in large, international cohorts.

RESUMEN

BACKGROUND: There are limited data on Coronavirus Disease 2019 (COVID-19) outcomes at a national level, and none after 60 days of follow up. The aim of this study was to describe national, 60-day all-cause mortality associated with COVID-19, and to identify risk factors associated with admission to an intensive care unit (ICU). METHODS: This was a retrospective cohort study including the first consecutive 5000 patients with COVID-19 in Qatar who completed 60 days of follow up by June 17, 2020. The primary outcome was all-cause mortality at 60 days after COVID-19 diagnosis. In addition, we explored risk factors for admission to ICU. RESULTS: Included patients were diagnosed with COVID-19 between February 28 and April 17, 2020. The majority (4436, 88.7%) were males and the median age was 35 years [interquartile range (IQR) 28-43]. By 60 days after COVID-19 diagnosis, 14 patients (0.28%) had died, 10 (0.2%) were still in hospital, and two (0.04%) were still in ICU. Fatal COVID-19 cases had a median age of 59.5 years (IQR 55.8-68), and were mostly males (13, 92.9%). All included pregnant women (26, 0.5%), children (131, 2.6%), and healthcare workers (135, 2.7%) were alive and not hospitalized at the end of follow up. A total of 1424 patients (28.5%) required hospitalization, out of which 108 (7.6%) were admitted to ICU. Most frequent co-morbidities in hospitalized adults were diabetes (23.2%), and hypertension (20.7%). Multivariable logistic regression showed that older age [adjusted odds ratio (aOR) 1.041, 95% confidence interval (CI) 1.022-1.061 per year increase; P < 0.001], male sex (aOR 4.375, 95% CI 1.964-9.744; P < 0.001), diabetes (aOR 1.698, 95% CI 1.050-2.746; P 0.031), chronic kidney disease (aOR 3.590, 95% CI 1.596-8.079, P 0.002), and higher BMI (aOR 1.067, 95% CI 1.027-1.108 per unit increase; P 0.001), were all independently associated with increased risk of ICU admission. CONCLUSIONS: In a relatively younger national cohort with a low co-morbidity burden, COVID-19 was associated with low all-cause mortality. Independent risk factors for ICU admission included older age, male sex, higher BMI, and co-existing diabetes or chronic kidney disease.

RESUMEN

Tocilizumab, an interleukin-6 inhibitor, may ameliorate the inflammatory manifestations associated with severe coronavirus disease 2019 (COVID-19) and thus improve clinical outcomes. This was a retrospective review of patients with laboratory-confirmed severe COVID-19 who received tocilizumab and completed 14 days of follow up. Twenty-five patients were included, median age was 58 years (interquartile range, 50-63) and the majority were males (92%). Co-morbidities included diabetes mellitus (48%), chronic kidney disease (16%), and cardiovascular disease (12%). Fever (92%), cough (84%), and dyspnea (72%) were the commonest presenting symptoms. All patients received at least two concomitant investigational antiviral agents. Median oral temperature was on day 1, 3, and 7 was 38.0°C, 37.3°C (P = .043), and 37.0°C (P = .064), respectively. Corresponding median C-reactive protein was 193 and 7.9 mg/L (P < .0001) and <6 mg/L (P = .0001). Radiological improvement was noted in 44% of patients by day 7% and 68% by day 14. Nine patients (36%) were discharged alive from intensive care unit and three (12%) died. The proportion of patients on invasive ventilation declined from (84%) at the time of tocilizumab initiation to 60% on day 7 (P = .031) and 28% on day 14 (P = .001). The majority (92%) of patients experienced at least one adverse event. However, it is not possible to ascertain which adverse events were directly related to tocilizumab therapy. In patients with severe COVID-19, tocilizumab was associated with dramatic decline in inflammatory markers, radiological improvement and reduced ventilatory support requirements. Given the study's limitations, the results require assessment in adequately powered randomized controlled trials.

RESUMEN

BACKGROUND: Mental health has not had the same public profile as physical health. This has contributed to the stigma associated with mental illness and to its treatments. Research investigating how the traditions and values amongst those with an Arab heritage contribute to stigmatizing beliefs, attitudes or actions in the provision of mental healthcare has not been widely reported. AIM: To systematically review the literature and summarize the findings of studies reporting stigmatizing beliefs, actions and attitudes toward treatment of people with mental illness in the Arab population. METHODS: PubMed, Ovid, Psycharticles and Embase were used to identify original studies of non-institutionalized Arab adults or children reporting findings relevant to stigma toward mental illness. A manual search of the bibliography of all selected original studies was also undertaken. Independent data extraction was performed by two reviewers, who then met to compare data and reach consensus. Findings were classified as stigmatizing beliefs, actions or attitudes toward mental health treatments. RESULTS: A total of 33 articles were retrieved for full review. Those utilizing qualitative methodology provided insight into the many ways mental illness is viewed and defined among those with an Arab heritage. Among the studies using quantitative methodology, most compared stigmatizing beliefs, attitudes toward mental health treatments or stigmatizing actions among different Arab populations, some also investigated correlations between characteristics of the Arab population tested with stigmatizing beliefs, actions and attitudes toward mental health treatments. Findings from studies undertaken in Qatar reported greater stigmatizing beliefs, actions or attitudes toward mental health treatments among Qatari versus non-Qatari Arabs. CONCLUSION: A large diversity in the stigmatizing beliefs, actions and attitudes toward treatment of mental illness within the Arab population were identified. The influence of cultural variations on stigma should be explored further and used to tailor anti-stigma interventions in this population.

RESUMEN

INTRODUCTION: Observations have shown a lack of evidence-based medicine (EBM) knowledge and skills among community pharmacy preceptors in Qatar. These skills are important when delivering evidence-based recommendations to healthcare providers and patients. The aim of this study was to explore the community pharmacy preceptors' knowledge and understanding of EBM and to identify challenges in applying this approach to community practice. METHODS: A survey instrument was developed to assess the knowledge of community pharmacy preceptors related to EBM. Knowledge-based questions were mapped according to National Association of Pharmacy Regulatory Authorities professional competencies for practicing pharmacists. The survey tool was administered to community pharmacy preceptors involved in mentoring Qatar University College of Pharmacy students. RESULTS: Twenty-six community pharmacy preceptors completed the survey with a response rate of 65%. The knowledge-based questions linked to drug information resulted in 18%, 36%, and 46% of correct, incorrect, and unsure responses respectively while the critical appraisal questions showed 18%, 27%, 55% of correct, incorrect, and unsure responses respectively. Major barriers to practicing EBM included lack of EBM training (81%) and interpreting study results (80%). CONCLUSIONS: Community pharmacy preceptors showed poor knowledge and understanding of EBM. These results and expressed needs by pharmacists support the development of a supplementary course to improve EBM skills.
