CONTEXT: Kidney is one of the vital organs maintaining homeostasis of body and thus dysfunction of kidney affects quality of life and health severely. Anticancer drugs, particularly chemotherapeutic agents, cause high toxicity leading kidney dysfunction and irreparable kidney injury. Therefore, attention has recently been paid to seeking out alternatives such as nature-based drugs that are effective but less toxic. In this regard, this systematic review article is to report and introduce the most important medicinal plants and their derivatives that are used to reduce anticancer drug-induced nephrotoxicity...

BACKGROUND: Secondary hyperparathyroidism (SHPT) is a common complication of chronic kidney disease (CKD) leading high mortality and even long-term morbidity. SHPT is manifested by elevation of parathyroid hormone (PTH) and accurate determining the level of serum PTH is very essential for early diagnosis of SHPT secondary to CKD. It is very important to match the values obtained for intact parathormone (iPTH) and 1- 84 PTH with the minimized measurement bias. OBJECTIVES: The present study aimed to first determine the agreement value between the iPTH and 1- 84 PTH measures in patients with hyperparathyroidism secondary to endstage renal disease under chronic hemodialysis...

BACKGROUND: Risk factors for cytomegalovirus (CMV) disease in renal transplant recipients have been evaluated in industrialized countries with relatively low CMV seroprevalence. OBJECTIVES: We aimed to determine which factors are related to this illness in a high CMV seroprevalence country. PATIENTS AND METHODS: A case-control study was performed with data from a 5-year follow-up of 260 kidney transplant recipients at our center. Odds ratios were calculated using the Mantel-Haenszel method...

BACKGROUND: The etiology of renal disease varies in different parts of the world. In the Middle East, half of all patients reaching end-stage are categorised as either unknown etiology or hypertension-related nephropathy. OBJECTIVES: To report a renal biopsy series, in a reproducible format and manner, so that data can be compared directly among other series. PATIENTS AND METHODS: Biopsies of native kidneys were performed in a 10-year period, at a tertiary referral hospital that provides the entire nephrology service for north Cyprus...

BACKGROUND: Acute interstitial nephritis (AIN) is an emerging cause of acute kidney injury (AKI) during the recent years. OBJECTIVES: There is no data about prevalence, causes, clinical manifestation and outcomes of AIN in our region. Hence, in this study we aimed to find the prevalence of AIN and describe the causes, clinical presentation, and the outcome of AIN in the native kidney biopsies. PATIENTS AND METHODS: We reviewed 934 native kidney biopsies from 2006 to 2014 and collected the data of patients with the diagnosis of AIN including medical history, clinical findings, para-clinical data, pathologic findings, treatment and outcomes...

BACKGROUND: Gram-negative bacteria are associated with an increase in rates of antibacterial resistance. In most low- and middle-income countries such as Iran, there is no continuous surveillance system for antibiotic resistance. OBJECTIVE: The purpose of this survey was to determine the pattern of antimicrobial sensitivity of gram-negative bacteria within 3 consecutive years at a nephrology ward of Nemazee hospital in Shiraz. MATERIALS AND METHODS: During a 3-year period from 2013 to 2015 at the adult nephrology ward, bacteriological data of all biological samples of hospitalized patients in favor of gram-negative microorganisms were analyzed retrospectively...

BACKGROUND: Oleuropein is a potent antioxidant and free-radical scavenger with antiinflammatory properties. OBJECTIVES: In the present study, we evaluated the protective effects of oleuropein on myeloperoxidase (MPO) activity, nitrite, urea, creatinine and glomerulosclerosis in alloxan-induced type 1 diabetic rats. MATERIALS AND METHODS: Thirty Sprague-Dawley male rats were randomly divided into 3 groups: group 1 as control; group 2 as untreated diabetic; and group 3 as treated with oleuropein 15 mg/kg i...

BACKGROUND: There exists a synergy between chronic kidney disease (CKD) and cardiovascular risk factors (CVRFs) with increased morbidity and poor outcomes. OBJECTIVES: Data relating to this clustering in black homogenous populations is scanty. We aim to investigate this relationship in Nigerian communities. PATIENTS AND METHODS: It was a cross-sectional observation study from semi-urban communities in South-West Nigeria. We used modified World Health Organization (WHO) questionnaire on chronic diseases (WHO STEPS) to gather information on socio-demographic data, biophysical and clinical characteristics...

BACKGROUND: Differential diagnosis between primary focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) is sometimes difficult as nephrotic syndrome is the main clinical symptom in both diseases. OBJECTIVES: This study has attempted to evaluate the urinary excretion of Th1 and Th2 cytokines as potential biomarkers in distinguishing the two types of nephrotic syndrome, and predicting outcome of renal function. PATIENTS AND METHODS: Thirty-six patients with FSGS (M/F 22/14, Age; 41...

BACKGROUND: One of the main therapeutic limitations of cisplatin (CP) is nephrotoxicity which is time-dependent. OBJECTIVES: The purpose of this study was to determine the optimal timing for initiation of CP toxicity. MATERIALS AND METHODS: Sixty male and female Wistar rats were randomly divided into five groups. All the animals in groups 2-5 received single dose of CP (10 mg/kg; i.p.), and were evaluated 25, 50, 75, and 100 hours after CP administration...

BACKGROUND: Monoclonal antibodies targeting vascular endothelial growth factor (VEGF), such as bevacizumab, are administered intravitreally for the treatment of wet or exudative age-related macular degeneration (ARMD). Systemic use of bevacizumab has been linked to a wide range of renal adverse effects including proteinuria and hypertension. CASE PRESENTATION: We present the case of a 77-year-old Caucasian male with a past medical history of hypertension, vitamin D deficiency and paroxysmal atrial fibrillation who presented to primary care clinic with a 2-week history of bilateral lower extremity edema, 2 months after completing four monthly intravitreal injections of bevacizumab for ARMD...
