Prevalence of Healthcare Associated Infections in Adults Recipients of Autologous Hematopoietic Stem Cell Transplantation in Qatar

Objective To analyze the prevalence and characteristics of Healthcare Associated Infections (HAI) in patients with hematologic malignancies who underwent Autologous Hematopoietic Stem Cell Transplantation (AHSCT) at the National Center for Cancer Care and Research (NCCCR) newly opened transplant unit in Qatar between October 2015 and October 2016 with global comparison of the bloodstream Infection (BSI) prevalence, one of the most prevalent complications after stem cell transplant. Methods The Center of Disease Control (CDC) definitions for laboratory-confirmed bloodstream infection (BSI), modified criteria for pneumonia and hospital-acquired infections were used. Statistical analysis was done using STATA version14. The entire healthcare associated infections (HAI) and other variables were described using means, proportions and 95% confidence intervals. Meta-Analysis of Observational Studies in Epidemiology guidelines was applied in conducting the meta-analysis. The systematic search in English was done in PubMed from 1970 (date of stem cell transplant kick off) to 2016. Inclusion was restricted to human hematology studies that included AHSCT. Statistical calculations allowing an accurate estimation of the prevalence were calculated using MetaXl version 5.3. The data extraction for both studies was done independently by two reviewers. Results Out of the sixteen patients, three developed infection leaving the overall infection rate to 18.75%. Chemotherapy induced gastroenteritis was documented in 68.7% of the cases, chemotherapy induced mucositis was documented in 43.7% of the cases. Most of the infections occurred during neutropenia (92.3%) and 69.2% of them during febrile neutropenia. No gastroenteritis was microbiologically confirmed, all were clinically documented infections. Bacterial infections accounted for 12.5% (2/16 cases) one upper respiratory tract infection and one urinary tract infection. Whereas viral infections, pneumonia and urinary tract infections were each 6.25% (1/16 cases respectively). There was no prevalence of bloodstream infection or central line associated bloodstream infection for any of the patients. As for the meta-analysis, the aggregated results were studied in the 10 included studies. Significant heterogeneity was noted among the studies (I2 = 99%; P = 0.0001), the pooled prevalence of blood stream infection among 55789 AHSCT patients from the ten studies was 6%, 95% CI: 0, 33. Conclusion This study provides original baseline data about the prevalence of HAI among AHSCT in NCCCR. These findings will be used for additional evaluation of the influence of infection prevention and control measures and therapeutic plans for these patients. They will also contribute to the enhancement of the quality of care in NCCCR, mainly in the hematopoietic stem cell transplant unit (HSCT) through the proper implementation of the infection control standards and proper implementation of antimicrobial stewardship program

Risk of wheezing and asthma exacerbation in children treated with paracetamol versus ibuprofen: a systematic review and meta-analysis of randomised controlled trials

Background Paracetamol and ibuprofen are the most commonly used medications for fever and pain management in children. While the efficacy appears similar with both drugs, there are contradictory findings related to adverse events. In particular, incidence of wheezing and asthma among children taking paracetamol compared to ibuprofen, remain unsettled. Methods We conducted a meta-analysis of randomized controlled trials (RCTs) that compared wheezing and asthma exacerbations in children taking paracetamol versus ibuprofen. A comprehensive search was conducted in five databases. RCTs reporting on cases of wheezing or asthma exacerbations in infants or children after the administration of paracetamol or ibuprofen were included. The pooled effect size was estimated using the Peto’s odds ratio. Results Five RCTs with 85,095 children were included in the analysis. The pooled estimate (OR 1.05; 95%CI 0.76–1.46) revealed no difference in the odds of developing asthma or presenting an exacerbation of asthma in children who received paracetamol compared to ibuprofen. When the analysis was restricted to RCTs that examined the incidence of asthma exacerbation or wheezing, the pooled estimate remained similar (OR 1.01; 95%CI 0.63–1.64). Additional bias adjusted quality effect sensitivity model yielded similar results (RR 1.03; 95%CI 0.84–1.28). Conclusion Although, Ibuprofen and paracetamol appear to have similar tolerance and safety profiles in terms of incidence of asthma exacerbations in children, we suggest high quality trials with clear definition of asthma outcomes after receiving ibuprofen or paracetamol at varying doses with longer follow-up are warranted for any conclusive findingThe publication of this article was funded by the Qatar National Library.

Epidemiology of respiratory infections among adults in Qatar (2012-2017).

Limited data is available about the etiology of influenza like illnesses (ILIs) in Qatar. This study aimed at providing preliminary estimates of influenza and other respiratory infections circulating among adults in Qatar. We retrospectively collected data of about 44,000 patients who visited Hamad General Hospital clinics, sentinel sites, and all primary healthcare centers in Qatar between 2012 and 2017. All samples were tested for influenza viruses, whereas about 38,000 samples were tested for influenza and a panel of respiratory viruses using Fast Track Diagnostics (FTD) RT-PCR kit. Among all ILIs cases, 20,278 (46.5%) tested positive for at least one respiratory pathogen. Influenza virus was predominating (22.6%), followed by human rhinoviruses (HRVs) (9.5%), and human coronaviruses (HCoVs) (5%). A detection rate of 2-3% was recorded for mycoplasma pneumonia, adenoviruses, human parainfluenza viruses (HPIVs), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ILIs cases were reported throughout the year, however, influenza, RSV, and HMPV exhibited strong seasonal peaks in the winter, while HRVs circulated more during fall and spring. Elderly (>50 years) had the lowest rates of influenza A (13.9%) and B (4.2%), while presenting the highest rates of RSV (3.4%) and HMPV (3.3%). While males had higher rates of HRVs (11.9%), enteroviruses (1.1%) and MERS CoV (0.2%), females had higher proportions of influenza (26.3%), HPIVs (3.2%) and RSV (3.6%) infections. This report provides a comprehensive insight about the epidemiology of ILIs among adults in the Qatar, as a representative of Gulf States. These results would help in improvement and optimization of diagnostic procedures, as well as control and prevention of the respiratory infections.This study was supported by funds from Hamad Medical Corporation (grant # 16335/16) and Qatar University (grant # QUCG-BRC-2018/2019-1)

Effectiveness of the neutralizing antibody sotrovimab among high-risk patients with mild-to-moderate SARS-CoV-2 in Qatar

ObjectivesTo estimate the real-world effectiveness of sotrovimab against severe, critical, or fatal COVID-19 in Qatar at a time in which most SARS-CoV-2 incidences occurred due to the BA.2 Omicron subvariant. MethodsWe conducted a matched case-control study among all individuals eligible for sotrovimab treatment per United States Food and Drug Administration guidelines in the resident population of Qatar. The odds of progression to severe forms of COVID-19 were compared in cases (treatment group) versus controls (eligible patients who opted not to receive the treatment). Subgroup analyses were conducted. ResultsA total of 3364 individuals were eligible for sotrovimab treatment during the study period, of whom 519 individuals received the treatment, whereas the remaining 2845 constituted the controls. The adjusted odds ratio of disease progression to severe, critical, or fatal COVID-19 comparing the treatment group to the control group was 2.67 (95% confidence interval 0.60-11.91). In the analysis including only the subgroup of patients at higher risk of severe forms of COVID-19, the adjusted odds ratio was 0.65 (95% confidence interval 0.17-2.48). ConclusionThere was no evidence for a protective effect of sotrovimab in reducing COVID-19 severity in a setting dominated by the BA.2 subvariant

HIV case reporting and HIV treatment outcomes in Qatar

AimThe aim of the paper is to provide an overview of available HIV case reporting and treatment data for in Qatar for the period 2015–2020.MethodsHIV case reporting data were analyzed by sex and mode of transmission. To construct HIV care continuum from the data available, we obtained information on the total number of HIV diagnosed patients on antiretroviral treatment (ART) between January 1st 2015 and December 31st 2020, number of patients on ART who had an HIV viral load test and the number who were virally suppressed (defined as having the viral load of less than 1,000 copies/mL).ResultsA total of 515 HIV cases were reported to the Ministry of Public Health since beginning of reporting in 1986, and that included Qatari nationals and expatriate residents diagnosed in Qatar. There was an increase in the annual number of newly reported HIV cases from 16 cases in 2015 (of these, 14 were males) to 58 cases in 2020 (of these, 54 were males). The total number of HIV diagnosed people on ART increased from 99 in 2015 to 213 in 2020. During 2020 the overall viral load testing coverage and viral load suppression among those tested for viral load in men were 72.5% and 93.1%, respectively, while in women these values were 60.4% and 84.4%, respectively.ConclusionDue to increase in newly reported HIV cases, there is a need to develop an effective HIV strategic information system in Qatar and data-driven and targeted national HIV response

Evaluation of Hospital Antimicrobial Stewardship Programs : Implementation, Process, Impact, and Outcomes, Review of Systematic Reviews

Antimicrobial Stewardship Programs (ASP) were introduced in healthcare as a public health priority to promote appropriate prescribing of antimicrobials, to reduce adverse events related to antimicrobials, as well as to control the escalating challenges of antimicrobial resistance. To deliver aimed outcome objectives, ASPs involve multiple connected implementation process measures. A systematic review was conducted to evaluate both concepts of ASPs. Guided by PRISMA frames, published systematic reviews (SR) focusing on ASPs restricted to secondary and tertiary healthcare were evaluated over the past 10 years involving all age groups. Out of 265 identified SR studies, 63 met the inclusion criteria. The majority were conducted in Europe and North America, with limited studies from other regions. In the reviewed studies, all age groups were examined, although they were conducted mainly on adults when compared to children and infants. Both process and outcomes measures of ASPs were examined equally and simultaneously through 25 different concepts, dominated by efficacy, antimicrobial resistance, and economic impact, while information technology as well as role of pharmacy and behavioral factors were equally examined. The main broad conclusions from the review were that, across the globe, ASPs demonstrated effectiveness, proved efficacy, and confirmed efficiency, while focused evaluation advocated that developed countries should target medium- and small-sized hospitals while developing countries should continue rolling ASPs across healthcare facilities. Additionally, the future of ASPs should focus on embracing evolving information technology to bridge the gaps in knowledge, skills, and attitude, as well as to enhance appropriate decision making

Clinical manifestations and outcome of Mpox infection in Qatar: An observational study during the 2022 outbreak

Mpox emerged in May 2022 as a global outbreak, mostly in hitherto non-endemic countries. To describe the epidemiological and clinical characteristics of mpox in Qatar, data were retrospectively retrieved for all laboratory-confirmed mpox cases diagnosed in Qatar between May and November 2022. Twelve cases were identified; of which 10 were males, and the median age was 33.5 years (IQR 24.5–37.5). Recent sexual exposure was reported in 9 patients, 6 of which were outside Qatar. Seven individuals reported exclusive heterosexual contact. Pleomorphic skin lesions were present in all cases, with anogenital involvement in 11. Fever (7/12) and lymphadenopathy (4/12) were relatively common. All cases were HIV-negative. The majority of cases had an uncomplicated and self-limiting clinical illness. In conclusion, the majority of early mpox infections in Qatar were purportedly acquired through heterosexual contact, primarily among middle-aged men. The clinical course was mostly uneventful. In the absence of active case finding and the mild and self-limiting nature of the clinical illness, undetected community transmission cannot be ruled out

The initial impact of a national BNT162b2 mRNA COVID-19 vaccine rollout

Objective: This study examined the initial impact of a national BNT162b2 vaccine rollout on SARS-CoV-2 infections in Qatar. Methods: All individuals who had completed ≥14 days of follow-up by 16 March 2021 after receiving the BNT162b2 vaccine were included. This study calculated incidence rates (IR) and their 95% confidence intervals (CI) during days 1–7, 8–14, 15–21, 22–28, and >28 days post-vaccination. Poisson regression was used to calculate incidence rate ratios (IRR) relative to the first 7-day post-vaccination period. Results: A total of 199,219 individuals with 6,521,124 person-days of follow-up were included. SARS-CoV-2 infection was confirmed in 1877 (0.9%), of which 489 (26.1%) were asymptomatic and 123 (6.6%) required oxygen support. The median time from first vaccination to SARS-CoV-2 confirmation was 11.9 days (IQR 7.7–18.2). Compared with the first 7-day post-vaccination period, SARS-CoV-2 infections were lower by 65.8–84.7% during 15–21, 22–28, and >28 days (P < 0.001 for each). For severe COVID-19, the incidence rates were 75.7–93.3% lower during the corresponding time periods (P < 0.001 for each). Conclusion: The results were consistent with an early protective effect of BNT162b2 vaccine against all degrees of SARS-CoV-2 severity
