The Tunnelled Atrial Catheter: A Promising Solution for Vascular Capital Depletion in Dialysis despite Associated Thrombi.

Introduction: Longer survival in dialysis led to a higher incidence of vascular access complications and failure. With the limited access to kidney transplantation programs and peritoneal dialysis, exhaustion of vascular access for hemodialysis is an increasingly common situation. Among the available options, atrial tunneled dialysis catheter (ATDC) has been reported as an effective vascular access in this population.

Hypercalcemia is a rare finding in this disease. In this report, we present a case of possible Dent's disease in a young adult male with hypercalcemia and chronic kidney disease.

Systemic lupus erythematosus presenting as lupus erythematosus tumidus and lupus nephritis: a case report.

Background: Lupus nephritis and lupus erythematosus tumidus (LET) are uncommon manifestations of systemic lupus erythematosus (SLE), and their coexistence as the initial presentation of SLE is exceedingly rare. Here, we report such a case, emphasizing the diagnostic challenges and therapeutic implications of this unusual association.

Case Report: A 38-year-old North African woman presented in Nephrology department with a history of lower extremity edema, fatigue, and weight loss of 3 kg in 4 weeks.

Incidence and challenges in management of hemodialysis catheter-related infections.

Catheter-related infections (CRI) are a major cause of morbidity and mortality in chronic hemodialysis (HD) patients. In this paper, we share our experience with CRI in HD patients. We recorded 49 cases of CRI among 167 patients during a period of 40 months (January 2018-April 2021).

Thirty years of experience with anti-neutrophil cytoplasmic antibody glomerulonephritis in Charles Nicolle Hospital-Tunisia: a retrospective cohort study.

Introduction: antineutrophil cytoplasmic antibodies (ANCA) associated Glomerulonephritis (GN) is rare but a life-threatening disease especially, particularly in patients with advanced renal failure at presentation. This study aims to evaluate the epidemiological, clinical and histopathological features of renal involvement and investigate factors associated with ESRD.

Methods: patients with renal biopsy-proven ANCA associated glomerulonephritis were included retrospectively over a thirty years period.

National Epidemiological Study about Hepatitis C Virus Infection among Dialysis Patients.

The World Health Organization estimates that 3% of the general population is infected with this virus. Hepatitis C remains the main viral infection in dialysis patients, and the severity of this infection is the risk of developing cirrhosis or hepatocarcinoma. We aim to determine the prevalence of hepatitis C in dialysis patients, to calculate the rate of hepatitis C virus (HCV) seroconversion, and to identify the risk factors for seroconversion.

Renal Amyloidosis: Epidemiological, Clinical, and Laboratory Profile in Adults from One Nephrology Center.

Background: Renal amyloidosis is one of the main differential diagnoses of nephrotic proteinuria in adults and the elderly. The aim of this study with the most important series in our country is to contribute to the epidemiological, clinical, and etiological study of the renal amyloidosis.

Methods: In a retrospective study carried out between 1975 and 2019, 310 cases of histologically proven and typed renal amyloidosis were selected for this study.

Readmissions to kidney transplantation department: incidence, causes and risk factors.

Introduction: hospital readmission after kidney transplantation is an important metric for health care quality, which associated with increased morbidity, costs and transition-of-care errors. It is influenced by population demographics and the comprehensiveness of the healthcare system. The aim of this study was to evaluate incidence causes and risk factors associated with hospital readmission within the first year after transplantation.

End-stage renal disease at dialysis initiation: Epidemiology and mortality risks during the first year of hemodialysis.

Chronic kidney disease (CKD) treated by hemodialysis (HD) is a worldwide major public health problem. Its incidence is getting higher and higher, leading to an alarming social and economic impact. The survival of these patients is significantly low, especially during the first year of treatment.
