Narrative Review of the Epidemiology of Hospital-Acquired Pneumonia and Ventilator-Associated Pneumonia in Gulf Cooperation Council Countries.

Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are the most common healthcare-associated infections, with rates varying between countries. Antimicrobial resistance (AMR) among common HAP/VAP pathogens has been reported, and multidrug resistance (MDR) is of further concern across Middle Eastern countries. This narrative review summarizes the incidence and pathogens associated with HAP/VAP in hospitals across Gulf Cooperation Council (GCC) countries.

Outcome of Transplant Recipients Infected with Omicron BA.1 and BA.2: A Single-Center Retrospective Study in Saudi Arabia.

SARS-COV-2 Triggers the Development of Class I and Class II HLA Antibodies in Recovered Convalescent Plasma Donors.

Various studies have shown that SARS-CoV-2 is a highly immunogenic virus. It is known that different types of immunogenic viral pathogens could trigger the formation of HLA antibodies. Therefore, there is a concern that the SARS-CoV-2 could also induce the development of HLA antibodies in volunteers, who donate convalescent plasma after their recovery from COVID-19.

Promoting cross-regional collaboration in antimicrobial stewardship: Findings of an infectious diseases working group survey in Arab countries of the Middle East.

Background: Antimicrobial resistance is a significant global issue that presents an increasing threat to patients' wellbeing. Although a global concern, the emergence of multi-drug resistant organisms is of particular significance in the Middle East. In recent years, this region has seen an alarming increase in antimicrobial resistance presenting a major challenge to physicians managing various infectious diseases.

Management of infections caused by WHO critical priority Gram-negative pathogens in Arab countries of the Middle East: a consensus paper.

Antimicrobial resistance is an important global issue that impacts the efficacy of established antimicrobial therapy. This is true globally and within the Arab countries of the Middle East, where a range of key Gram-negative pathogens pose challenges to effective therapy. There is a need to establish effective treatment recommendations for this region given specific challenges to antimicrobial therapy, including variations in the availability of antimicrobials, infrastructure and specialist expertise.

Background: Candidaemia is the most common form of invasive candidiasis. Resistant Candida blood stream infection (BSI) is rising, with limitations on the development of broader-spectrum antifungal agents worldwide. Our study aimed to identify the occurrence of antifungal-resistant candidaemia and the distribution of these species, determine the risk factors associated with antifungal resistance and evaluate the association of antifungal-resistant candidaemia with the length of intensive care unit (ICU) and hospital stay and with 30-day mortality.

Systematic review and meta-analysis of the safety of erythromycin compared to clarithromycin in adults and adolescents with pneumonia.

Macrolides are recommended for the treatment of community-acquired pneumonia (CAP). It is debatable whether erythromycin is associated with more adverse drug reactions (ADRs) compared to clarithromycin, and both are recommended in clinical practice guidelines. This meta-analysis aim is to compare ADRs in CAP patients treated with erythromycin versus clarithromycin.

Background: Carbapenem-resistant Enterobacteriaceae (CRE) represent an important global threat. The aim of this study is to describe the clinical course and outcomes of patients with CRE infections treated with ceftazidime-avibactam (CAZ-AVI) compared to patients treated with other agents.

Methods: A retrospective cohort study of patients with established CRE infections from January 2017 until August 2018 was conducted.

Family cluster of multi-drug resistant tuberculosis in Kingdom of Saudi Arabia.

We describe the clinical and genetic characteristics of multi-drug resistant tuberculosis (MDR-TB) in a family cluster in the western region of Kingdom of Saudi Arabia diagnosed between 2012 and 2016. All cases had risk factors for tuberculosis acquisition and they were not household contacts of the index case. Genetic analysis detected both MDR-TB and pre-extensively drug-resistant tuberculosis (pre-XDR TB) strains in the index case and confirmed tuberculosis transmission between two cases.

Quality of life reported by survivors after hospitalization for Middle East respiratory syndrome (MERS).

Introduction: Data are lacking on impact of Middle East Respiratory Syndrome (MERS) on health-related quality of life (HRQoL) among survivors.

Methods: We conducted a cross-sectional survey of MERS survivors who required hospitalization in Saudi Arabia during 2016-2017, approximately 1 year after diagnosis. The Short-Form General Health Survey 36 (SF-36) was administered by telephone interview to assess 8 quality of life domains for MERS survivors and a sample of survivors of severe acute respiratory infection (SARI) without MERS.

Noninvasive ventilation in critically ill patients with the Middle East respiratory syndrome.

Background: Noninvasive ventilation (NIV) has been used in patients with the Middle East respiratory syndrome (MERS) with acute hypoxemic respiratory failure, but the effectiveness of this approach has not been studied.

Methods: Patients with MERS from 14 Saudi Arabian centers were included in this analysis. Patients who were initially managed with NIV were compared to patients who were managed only with invasive mechanical ventilation (invasive MV).

Management and outcome of latent tuberculosis in living renal transplant donors.

In regions where tuberculosis (TB) is endemic, up to 15% of kidney transplant recipients develop Mycobacterium tuberculosis infections (TBI), typically with an increased risk of disseminated disease and allograft loss. To reduce these risks, donors and recipients with latent TB usually receive isoniazid (INH) prophylaxis. However, it is unclear whether latent TB in donors justifies routine prophylaxis of recipients.

Macrolides in critically ill patients with Middle East Respiratory Syndrome.

Objectives: Macrolides have been reported to be associated with improved outcomes in patients with viral pneumonia related to influenza and other viruses, possibly because of their immune-modulatory effects. Macrolides have frequently been used in patients with Middle East Respiratory Syndrome (MERS). This study investigated the association of macrolides with 90-day mortality and MERS coronavirus (CoV) RNA clearance in critically ill patients with MERS.
