Isolated microhematuria in potential kidney donors: evaluating kidney biopsy findings with dipstick urinalysis and urine microscopy results.

Background: Isolated microhematuria (IMH) can signal hidden glomerular disease, necessitating detailed evaluations for potential kidney donors, including kidney biopsies. The optimal strategy for deciding on kidney biopsies remains unclear. While the British Transplant Society supports dipstick analysis, KDIGO focuses solely on urine microscopy.

Adherence to Cysteamine Therapy Among Patients Diagnosed with Cystinosis in Saudi Arabia: A Prospective Cohort Study.

Cystinosis is a rare autosomal recessive disorder in which cystine crystals accumulate within the cellular lysosomes, causing damage to multiple organs. Due to challenges with the stringent cysteamine treatment regimen and side effects, adherence is often sub-optimal. This study aimed to assess the level of adherence to cysteamine therapy among cystinosis patients in Saudi Arabia and its impact on their quality of life.

Long-Term Safety of Roflumilast in Patients with Chronic Obstructive Pulmonary Disease, a Multinational Observational Database Cohort Study.

Purpose: This study evaluated the long-term safety of roflumilast in patients with chronic obstructive pulmonary disease or chronic bronchitis using electronic healthcare databases from Germany, Norway, Sweden, and the United States (US).

Patients And Methods: The study population consisted of patients aged ≥40 years who had been exposed to roflumilast and a matched cohort unexposed to roflumilast. The matching was based on sex, age, calendar year of cohort entry date (2010-2011, 2012, or 2013), and a propensity score that included variables such as demographics, markers of chronic obstructive pulmonary disease (COPD) severity and morbidity, and comorbidities.

The Clinical Manifestations and Disease Burden of Cystinosis in Saudi Arabia: A Single-Tertiary Center Experience.

Background: There is a lack of regional and local evidence that describes the nature of cystinosis, a multiorgan accumulation of cystine, and its extent of organ damage. Therefore, this study aimed to determine the outcomes of cystinosis in patients who were followed up at a large tertiary care hospital.

Methods: Medical records of patients with cystinosis were retrospectively reviewed.

Awareness, Attitudes, and Willingness: A Cross-Sectional Study of Organ Donation in Saudi Arabia.

Background: Organ transplantation is inherently dependent on the availability of organ donors. There is a noticeable paucity of literature addressing the rates of organ donation registration and the awareness of Islamic regulations (Fatwa) regarding organ donation within Saudi Arabia. Our study aimed to evaluate the level of organ donation registration, awareness of Islamic regulations, and knowledge of the Saudi Center for Organ Transplantation (SCOT) within the Saudi society.

Effect of Arabic Qahwa on Blood Pressure in Patients with Stage One Hypertension in the Eastern Region of Saudi Arabia.

Hypertension (HT), which is a condition of increased blood pressure (BP), is a major health problem globally. In Saudi Arabia, morbidity and mortality rates are increasing due to HT. Arabic Qahwa (AQ) is a commonly consumed beverage in Saudi Arabia and has numerous health benefits.

Outcomes of Kidney Transplantation in Older Recipients.

BACKGROUND Access to kidney transplantation is limited for elderly patients with end-stage renal disease (ESRD), who often die while on the waiting list or receive kidneys from marginal deceased donors. In our transplantation center, most donated kidneys were from younger living relatives, in whom donations to elderly outcomes were not previously studied. In this study, we aimed to determine the short- and long-term outcomes of patients aged ³65 years to justify the use of kidneys from younger donors in older recipients.

Coronavirus disease 2019 vaccine in pediatric post-kidney transplantation.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and the resulting disease, coronavirus disease 2019 (COVID-19), have spread to millions of persons worldwide. Many vaccines have been developed; however, their efficacy in pediatric solid organ transplant recipients is yet to be determined.

Methods: This is a prospective observational, non-interventional single-center study on the safety and efficacy of a COVID-19 vaccine (BNT162b2) in pediatric kidney transplant recipients.

Mpox Perceptions and Vaccine Advocacy among the Healthcare Workers of Solid Organ Transplant Centers: A Multicenter, Cross-Sectional Survey in Saudi Arabia.

Methods: A cross-sectional survey was conducted among solid organ transplant HCWs in Saudi Arabia from 15 August to 5 September 2022. A total of 199 responses were received from participants primarily working in the kidney (54.

Comparison of the safety and immunogenicity of the BNT-162b2 vaccine and the ChAdOx1 vaccine for solid organ transplant recipients: a prospective study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its resulting disease, coronavirus disease 2019 (COVID-19), has spread to millions of people worldwide. Preliminary data from organ transplant recipients have shown reduced seroconversion rates after the administration of different SARS-CoV-2 vaccination platforms. However, it is unknown whether different vaccination platforms provide different levels of protection against SARS-CoV-2.

Population-based survival for cancer patients in Saudi Arabia for the years 2005-2009.

The Saudi Cancer Registry reported in 2007 the 5-year observed survival for the most common cancer sites for the years 1994-2004. In this report we looked at the cancer survival in the period 2005-2009 and evaluated the trend over the 15 years period from 1994 to 2009. Cases of the top 14 cancer sites reported by the population based Saudi Cancer Registry from 1 January 2005 to December 31, 2009, were submitted for survival analysis.

The Rare Occurrence of Post-tonsillectomy Surgical Emphysema.

Subcutaneous facial emphysema is a rare complication of tonsillectomy that can lead to infection, upper airway obstruction or invasion into the thorax. The latter can cause pneumomediastinum or pneumothorax, with possible subsequent cardiorespiratory function impairment. Although multiple causes are suggested in the literature, the main causative factor is still unclear.

Standard induction with basiliximab versus no induction in low immunological risk kidney transplant recipients: study protocol for a randomized controlled trial.

Background: Induction therapy with IL-2 receptor antagonist (IL2-RA) is recommended as a first-line agent in low immunological risk kidney transplant recipients. However, the role of IL2-RA in the setting of tacrolimus-based immunosuppression has not been fully investigated.

Aims: To compare different induction therapeutic strategies with 2 doses of basiliximab vs.

Coronavirus Disease-19: Disease Severity and Outcomes of Solid Organ Transplant Recipients: Different Spectrums of Disease in Different Populations?

Background: Coronavirus disease-19 (COVID-19) is associated with significant mortality. The elderly, patients with comorbidities, and solid organ transplant (SOT) recipients are particularly at risk. We observed a low incidence of severe disease in our population and aimed to determine the outcomes of COVID-19 (disease severity/intensive care unit [ICU] admissions/mortality) in SOT recipients.

Severe hyponatremia after donor nephrectomy.

Living kidney donation is safe and established but can lead to short- and long-term complications. Hyponatremia is the most common disorder of body fluid and electrolyte balance in clinical practice, associated with increased morbidity, mortality, and the length of hospital stay. A correct diagnosis of the etiology of hyponatremia is critical, both to determine correct management and prognosis.

ABO incompatible kidney transplantation: the Saudi experience.

Although the outcomes of ABO-incompatible (ABOi) kidney transplant recipients are quite favorable, these patients are at increased risk of early antibody-mediated rejection (AMR) and graft loss. Some studies have also shown high mortality in the ABOi group mainly due to increased risk of infections. The AMR rates have been reported anywhere from <10% to >50% in the literature.

ABO-Incompatible Kidney Transplantation: Low Rates of Infectious Complications and Excellent Patient Survival.

Background: A significant gap exists between demand and supply of organs for patients with end-stage renal disease. To increase the donor pool, kidney transplantation is performed across ABO- and HLA-incompatible barriers. ABO-incompatible kidney transplant (ABOi-KT) recipients are at increased risk of antibody-mediated rejection, infection, and mortality.

Successful Treatment With Abatacept in Recurrent Focal Segmental Glomerulosclerosis After Kidney Transplant.

Primary focal segmental glomerulosclerosis recurrence occurs in 10% to 50% of recipients after kidney transplant and may affect both children and adults. Treatment after recurrence with plasma exchange and immunosuppression is quite variable and challenging, and those who do not respond usually progress to allograft failure. Podocyte injury and B7-1 expression and subsequently its blockade (abatacept) have been reported to be associated with complete remission of proteinuria in 4 patients with focal segmental glomerulosclerosis recurrence after kidney transplantation and in 1 patient with focal segmental glomerulosclerosis in native kidney.

Ramadan Fasting in Kidney Transplant Recipients: A Single-Centre Retrospective Study.

Background: Fasting during the lunar month of Ramadan is mandatory to all healthy adult Muslims. Renal transplant recipients are often worried about the impact of fluid and electrolyte deprivation during fasting on the function of their allograft. We aimed to examine the effect of fasting Ramadan on the graft function in renal transplant recipients.

Histopathologic Findings of Potential Kidney Donors With Asymptomatic Microscopic Hematuria: Impact on Donation.

Introduction: Isolated microscopic hematuria (IMH) is not uncommon in potential kidney donors.

Aim: The aim was to study the kidney biopsy findings of potential kidney donors with IMH and the impact of the histopathologic diagnoses on the decision to accept or decline such donors from kidney donation.

Methods: In this retrospective study, all the potential kidney donors with IMH were identified from the medical records of patients who underwent kidney biopsies between January 2010 and December 2016.

Mycobacterium tuberculosis in solid organ transplantation: incidence before and after expanded isoniazid prophylaxis.

Background: The risk of tuberculosis is increased in solid organ transplantation. Rates remain high in developed and developing countries. We developed protocols to better identify transplant recipients at risk of tuberculosis and initiate interventions to prevent tuberculosis.

Vascular access types in patients starting hemodialysis after failed kidney transplant: does close nephrology follow-up matter?

Background: Native arteriovenous fistulae (AVFs) are preferred while central venous catheters (CVCs) are least suitable vascular access (VA) in patients requiring hemodialysis (HD). Unfortunately, around 80% of patients start HD with CVCs. Late referral to nephrologist is thought to be a factor responsible for this.

New-onset diabetes after kidney transplantation: Incidence, risk factors, and outcomes.

Many patients develop new-onset diabetes after kidney transplantation (NODAT). Its incidence and epidemiology are unknown in the Saudi population. We aimed to study the incidence, epidemiology, and outcomes of kidney transplant recipients who developed NODAT.
