Hemodialysis during Lockdown Due to Coronavirus Disease 2019 Pandemic in Eastern Saudi Arabia.

The first case of Coronavirus disease-2019 (COVID-19) in the Kingdom of Saudi Arabia was confirmed in the city of Qatif in March 2020. As a result, Qatif was placed under lockdown for two months in an attempt to prevent the widespread of COVID-19. Doing hemodialysis (HD) during lockdown was a new and challenging experience that we recently have faced.

Novel Haplotype Indicator for End-Stage Renal Disease Progression among Saudi Patients.

Background: End-stage renal disease (ESRD) is the result of hypertensive nephrosclerosis and chronic glomerular diseases and is associated with high morbidity and mortality. There are strong heritable components in the manifestation of the disease with a genetic predisposition to renal disorders, including focal segmental glomerulosclerosis and arterionephrosclerosis. Recent studies in genetics have examined modifiable risk factors that contribute to renal disease, and this has provided a deep insight into progressive kidney disease.

Assessing known chronic kidney disease associated genetic variants in Saudi Arabian populations.

Background: Genome wide association studies of patients with European descent have identified common variants associated with risk of reduced estimated glomerular filtration rate (eGFR). A panel of eight variants were selected to evaluate their association and prevalence in a Saudi Arabian patient cohort with chronic kidney disease (CKD).

Methods: Eight genetic variants in four genes (SHROOM3, MYH9, SLC7A9, and CST3) were genotyped in 160 CKD patients and 189 ethnicity-matched healthy controls.

End-stage renal disease in patients with sickle cell disease.

Sickle cell nephropathy is a severe complication of sickle cell disease (SCD) that has a wide range of manifestations, from asymptomatic microalbuminuria to end-stage renal disease (ESRD). The data on patients with SCD who develop ESRD are scarce. The aim of this study was to explore the course of patients with SCD who developed ESRD and received renal replacement therapy (RRT).

Elevated Fibroblast Growth Factor 23 Concentration: Prediction of Mortality among Chronic Kidney Disease Patients.

Background: The osteocyte-derived hormone, fibroblast growth factor 23 (FGF23), regulates the phosphorus metabolism and suppresses 1,25-dihydroxyvitamin D production, thereby mitigating hyperphosphatemia in patients with renal disorders. An elevated FGF23 level is suggested to be an early biomarker of altered phosphorus metabolism in the initial stages of chronic kidney disease (CKD) and acts as a strong predictor of mortality in dialysis patients. In the Saudi population, there is no report on the FGF23 level in CKD patients to date.

Concept and design of a genome-wide association genotyping array tailored for transplantation-specific studies.

Background: In addition to HLA genetic incompatibility, non-HLA difference between donor and recipients of transplantation leading to allograft rejection are now becoming evident. We aimed to create a unique genome-wide platform to facilitate genomic research studies in transplant-related studies. We designed a genome-wide genotyping tool based on the most recent human genomic reference datasets, and included customization for known and potentially relevant metabolic and pharmacological loci relevant to transplantation.

Polymorphism in methylenetetrahydrofolate reductase, plasminogen activator inhibitor-1, and apolipoprotein E in hemodialysis patients.

The methylenetetrahydrofolate reductase (MTHFR) gene polymorphism, apolipoprotein E (apo epsilon4) gene polymorphism and polymorphism of plasminogen activator inhibitor-1 (PAI-1) have been shown to be associated with end-stage renal disease (ESRD). To determine the prevalence of these mutations in Saudi patients with ESRD on hemodialysis, we studied the allelic frequency and genotype distribution in patients receiving hemodialysis and in a control group, all residing in the Eastern Province of Saudi Arabia. The genotypes were determined using allele specific hybridization procedures and were confirmed by restriction fragment length polymorphism.

Increased Prevalence of Glycoprotein IIb/IIIa Leu 33 Pro Polymorphism in End Stage Renal Disease Patients on Hemodialysis.

Traditional atherosclerosis risk factors cannot elucidate the increased prevalence of cardiovascular events in end stage renal disease (ESRD) patients on hemodialysis. A previous study has indicated a strong association of the PI(A1/A2) polymorphism with myocardial infarction, diabetes and renal allograft rejection. In this investigation, we determined the prevalence of the PI(A1/A2) polymorphism of platelet glycoprotein (GP) IIb/IIIa in ESRD patients on hemodialysis in the Eastern Province of Saudi Arabia.

Renal replacement therapy in end-stage sickle cell nephropathy: presentation of two cases and literature review.

Chronic renal failure develops in 4-18% of patients with sickle cell anemia. Hemodialysis and kidney transplant are viable options in the management of end-stage renal disease in patients with sickle cell disease (SCD). Information on kidney disease among Saudi patients with SCD is non-existing.

Co-existence of tuberous sclerosis and the fanconi syndrome in two saudi male siblings: report on two cases.

In this report, we present two cases of familial tuberous sclerosis co-existing with the Fanconi Syndrome. Both cases presented with history of failure to thrive and mental retardation associated with hypokalemic metabolic acidosis. To our knowledge, the association between tuberous sclerosis and the Fanconi Syndrome has not been reported previously.

Beneficial effects of maintenance intravenous iron saccharate in hemodialysis patients.

We evaluated in this study the effects of regular use of maintenance intravenous (IV) iron saccharate on the hematological parameters, iron stores and erythropoietin (EPO) requirement in a group of stable hemodialysis (HD) patients. We maintained 34 stable HD patients (14 (41.2%) males) with a mean age of 43.

Gastroduodenal lesions and Helicobacter pylori infection in hemodialysis patients.

Objective: The purpose of this prospective study is to determine the prevalence of upper gastrointestinal (GI) abnormalities and Helicobacter pylori (H. pylori) infection among stable chronic hemodialysis (HD) patients.

Methods: The study was carried out at King Fahd Hospital of the University, Al-Khobar, Kingdom of Saudi Arabia during the period January 1996 to June 1997.

Does Helicobacter pylori infection in chronic renal failure increase the risk of gastroduodenal lesions? A prospective study.

Background: Helicobacter pylori (H.pylori) plays an important role in gastroduodenal disease. However, there are few data concerning the epidemiology of H.

A prospective study of hemodialysis access-related bacterial infections.

The objective of this study was to describe hemodialysis vascular-access related infections that occurred in hemodialysis patients over an 18-month period. The study is a prospective descriptive analysis of incidence infection rates in a hemodialysis unit in a tertiary-care medical center. Prospective surveillance for hemodialysis vascular access-related infection was performed for all patients undergoing hemodialysis from November 1999 through April 2001 at King Fahd Hospital of King Faisal University, Al-Khobar, Saudi Arabia.
