Prevalence of Carbapenem-Resistant Enterobacteriaceae in Western Saudi Arabia and Increasing Trends in the Antimicrobial Resistance of Enterobacteriaceae.

Purpose:  The aim of the study is to estimate the prevalence rate of carbapenem-resistant Enterobacteriaceae (CRE) and to determine the types of carbapenemase genes present in patients admitted to King Abdulaziz Medical City (KAMC-J) and King Abdulaziz University Hospital (KAUH), both in Jeddah, Saudi Arabia.

Methods:  A total of 180 isolates were analyzed which were included on the basis of retrospective chart review of patients from KAMC-J and KAUH between 1 April 2017 to 30 March 2019. The prevalence of carbapenemase genes was evaluated by Xpert® Carba-R (Cepheid, Sunnyvale, CA, USA).

Assessing the Effectiveness of Antibiotic Therapy Against Common Gram-Negative Bacteria in a Saudi Arabian Hospital Using the Drug Resistance Index.

Introduction: Assessing the effectiveness of antibiotics and communicating the problem of resistance are essential when devising antimicrobial stewardship programs (ASPs) in hospital settings. The Drug Resistance Index (DRI) is a useful tool that combines antibiotic consumption and bacterial resistance into a single measure. In this study, we used the DRI to assess the impact of introducing a new antibiotic restriction form on antibiotic effectiveness for the treatment of Gram-negative infections in the intensive care unit (ICU).

Vascular endothelial growth factor-C in patients with breast cancer.

Metastatic spread of tumours is the major cause of death in patients with breast cancer. Despite the importance of the lymphatic system in tumour metastasis, little is known about the role of lymphangiogenesis in tumour growth and metastasis. This study was undertaken to evaluate the potential usefulness of plasma levels of lymphanagiogenesis factor, vascular endothelial cell growth factor-C (VEGF-C) as a prognostic factor in 122 patients with breast cancer.

Plasma CD105, TGFbeta-1, TGFbeta-3 and the ligand/receptor complexes in children with acute lymphoblastic leukaemia.

The role of angiogenesis in solid tumours is well recognised, but its importance in haematological malignancies is less well understood. In leukaemia, mainly the determination of microvascular density utilising immunohistochemistry in the bone marrow trephines and the measurement of soluble angiogenic factors have led to the recognition that angiogenesis may be important in leukaemia as well. In this study, the soluble form of the endothelial cell activation/proliferation (i.

Candidemia and the susceptibility pattern of Candida isolates in blood.

Objective: Candida species has become one of the most common blood isolates as well as one of the leading causes of nosocomial bloodstream infections. The purpose of our study was to determine the prevalence of Candida species among our bloodstream infecting organisms and the susceptibility pattern of the Candida isolates to antifungal agents.

Methods: A prospective study was carried out in the Division of Microbiology, King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia of all positive blood cultures for Candida species.

Enterococcus faecalis endocarditis.

The increasing usage of cephalosporins, to which the enterococci are resistant, has resulted in the rising number of enterococcal infections worldwide. Enterococci are a normal part of the flora of the human gastrointestinal tract, buccal cavity, perineal skin, vagina, urethra and gallbladder, but may occur as pathogens in a number of sites causing urinary tract infections, intra-abdominal infections, fatal bacteremia, meningitis and endocarditis. A Saudi male who developed enterococcal endocarditis with vegetations on both aortic and mitral valves required mitral and aortic valve replacement.
