Investigation of IgG Titers in Hemodialysis Patients and Controls Following Administration of the COVID-19 Vaccine.

Introduction: End-Stage Renal Disease (ESRD) patients necessitate dialysis when kidney transplantation is not feasible. Hemodialysis patients exhibit higher mortality rates compared to the general population due to uremia and an increased burden of comorbidities. In this vulnerable population, defective innate and adaptive immunity contribute to infectious diseases being a leading cause of hospitalization and mortality.

BK Viremia among Iranian Renal Transplant Candidates.

Background: Primary infection with BK virus (BKV) is occurred during childhood and usually asymptomatic, but after initial infection, BKV may persist lifelong in the kidney and genitourinary tract. Reactivation may occur in individuals with compromised immunity such as renal transplant recipients. Due to the role of BKV in BK virus-associated nephropathy (BKVAN) and potentially renal allograft rejection, the detection of BKV in renal transplant candidates is very important.

Frequency and subtype of BK virus infection in Iranian patients infected with HIV.

Human polyomavirus BK virus (BKV) is a double-stranded DNA virus that infects approximately 90 % of the general population as a subclinical or mild infection. In immunosuppressed patients, such as HIV cases, BKV may be reactivated resulting hemorrhagic cystitis and tubulointerstitial nephritis. However, there are limited studies on prevalence and molecular epidemiology of BKV in Iran.
