ABSTRACT

Proteinuria is a manifestation of sickle cell anemia (SCA)-related renal disease and is a risk factor of renal impairment. Angiotensin-converting enzyme (ACE) inhibitors have benefits, but their role in SCA remains undefined. This study aimed to assess the role of lisinopril, an ACE inhibitor, in reducing proteinuria in SCA patients. Thirty-five patients older than 15 years with known SCA (HbSS or HbS-ß0) and a 24-h urinary protein level of 150 mg or more participated in this study. Urine was collected over 24 h to quantify proteinuria. The patients had a mean age of 28.5 ± 6.98 years. The median 24-h urinary protein before treatment was 0.3006 g and that after treatment was 0.150 g (P = 0.01). After a median follow-up of 38 months, 24-h urinary protein decreased in 27 (77%) patients and normalized in 18 (52%) patients. Urinary protein increased in 2 (6%) patients and remained stable (no change) in 6 (17%) patients. There was no significant difference in blood pressure (BP) before and after treatment. The average dose of lisinopril was 5 mg. Twenty patients were still on lisinopril at last follow-up. The reasons for stopping lisinopril included normalization of protein, noncompliance, adverse effects, and pregnancy. Lisinopril effectively reduced proteinuria in SCA patients, without significantly reducing BP. Only a few patients developed adverse effects, including coughing, dizziness, and diarrhea. It is unclear how long lisinopril should be continued and whether it can be stopped in patients with normalized urinary protein.

ABSTRACT

Multidrug-resistant Klebsiella pneumoniae (MDR-KP) is a major public health problem that is globally associated with disease outbreaks and high mortality rates. As the world seeks solutions to such pathogens, global and regional surveillance is required. The aim of the present study was to examine the antimicrobial susceptibility pattern and clonal relatedness of Klebsiella pneumoniae isolates collected for a period of three years through pulse field gel electrophoresis (PFGE). Isolate IDs, antimicrobial assays, ESBL-production, and minimum inhibitory concentrations (MICs) were examined with the Vitek 2 Compact Automated System. IDs were confirmed by 16S rRNA gene sequencing, with the resulting sequences being deposited in NCBI databases. DNA was extracted and resistance genes were detected by PCR amplification with appropriate primers. Isolates were extensive (31%) and multidrug-resistant (65%). Pulsotype clusters grouped the isolates into 22 band profiles that showed no specific pattern with phenotypes. Of the isolates, 98% were ESBL-KP, 69% were carbapenem-resistant Enterobacteriaceae (CRE) strains, and 72.5% comprised the carriage of two MBLs (SIM and IMP). Integrons (ISAba1, ISAba2, and IS18) were detected in 69% of the MDR-KP. Additionally, OXA-23 was detected in 67% of the isolates. This study therefore demonstrates clonal diversity among clinical K. pneumoniae, confirming that this bacterium has access to an enormous pool of genes that confer high resistance-developing potential.

ABSTRACT

It has previously been shown that carbapenem-resistant Acinetobacter baumannii are frequently detected in Saudi Arabia. The present study aimed to identify the epidemiology and distribution of antibiotic resistance determinants in these bacteria. A total of 83 A. baumannii isolates were typed by pulsed-field gel electrophoresis (PFGE), and screened by PCR for carbapenemase genes and insertion sequences. Antibiotic sensitivity to imipenem, meropenem, tigecycline, and colistin were determined. Eight different PFGE groups were identified, and were spread across multiple hospitals. Many of the PFGE groups contained isolates belonging to World-wide clone 2. Carbapenem resistance or intermediate resistance was detected in 69% of isolates. The bla VIM gene was detected in 94% of isolates, while bla OXA-23-like genes were detected in 58%. The data demonstrate the co-existence and wide distribution of a number of clones of carbapenem-resistant A. baumannii carrying multiple carbapenem-resistance determinants within hospitals in the Eastern Region of Saudi Arabia.
