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.

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.

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.

Nephrotic syndrome in elderly: Etiologies, management, and prognosis.

The elderly population has significantly increased in the world. Nephrotic syndrome (NS) is one manifestation of glomerular nephropathy in the elderly. The objective of our study is to determine NS particularities in the elderly and to identify the factors predicting progression to chronic end-stage renal disease (ESRD).

[Renal involvement in sarcoidosis: Prognostic and predictive factors].

Introduction: Sarcoidosis is a systemic granulomatous disease that primarily affects the respiratory system and lymphatic vessels. Renal involvement is rare, poorly studied and found in less than 10% of cases. The objective of our study was to identify factors of poor renal prognosis and predictive factors of renal involvement during sarcoidosis.

Tubulointerstitial nephritis due to sarcoidosis: Clinical, laboratory, and histological features and outcome in a cohort of 24 patients.

Renal involvement is rare in systemic sarcoidosis. Among renal manifestations, tubulointerstitial nephritis (TIN) is the most commonly reported finding. We conducted the current study to investigate the clinical, laboratory, and histological features and to analyze the outcome of TIN due to sarcoidosis.

Clinical study on autosomal dominant polycystic kidney disease among North Tunisians.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disease, which usually manifests in adulthood. It is characterized by the development of multiple cysts in the kidneys and many other extrarenal manifestations. We aimed to determine the factors that contribute to the progression of ADPKD to end-stage renal disease (ESRD).

Renal amyloidosis in ankylosing spondylitis: A monocentric study and review of literature.

Secondary renal amyloidosis (RA) is the most common type of renal involvement in ankylosing spondylitis (AS). We assessed the epidemiologic and clinico-biological profile of AS patients with RA, to analyze treatment modalities and prognostic aspects, and to determine predictive factors of RA during AS. This was a retrospective study including 13 cases of RA among 212 cases who presented with AS, during the period from 1978 to 2006.

Factors associated with relapse of lupus nephritis: A single center study of 249 cases.

This is a retrospective cohort study over 20 years (1990-2013) that included all patients with biopsy-proven lupus nephritis (LN) followed up at our nephrology department. We aimed to determine the clinicobiologic predictors of flare-up of LN. Flare was defined as an increase in systemic lupus erythematosus (SLE) disease activity index (SLEDAI) score of at least four points.

Acute kidney injury with granulomatous interstitial nephritis and vasculitis revealing sarcoidosis.

Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement.

Predictive factors of mortality in a tunisian cohort with systemic lupus erythematosus.

Mortality in systemic lupus erythematosus (SLE) has decreased with the advent of immunosuppressive therapy and the development of hemodialysis. This study aims to evaluate the survival rate, factors of poor prognosis, and causes of death in SLE in a Tunisian series. The records of all SLE patients followed up in a single center during 1974-2014 were reviewed.

Tuberculosis After Renal Transplant.

Tuberculosis is one of the leading infections after renal transplant, particularly in developing countries where the incidence and prevalence in the general population are high. Diagnosis requires bacteriologic and histologic confirmation. Interactions among the antitubercular drugs and the immunosuppressive agents have to be considered while prescribing, and surveillance for adverse effects is required.

Outcome of Kidney Transplant in Patients with Polycystic Kidney Disease: A Single-Center Study in Tunisia.

Objectives: Autosomal dominant polycystic kidney disease is a common cause of end-stage renal disease and a common indication for renal transplant. This study was undertaken to evaluate the demographics, outcomes, and complications of renal transplant in patients with autosomal dominant polycystic kidney disease compared with other nephropathies.

Materials And Methods: In a retrospective case-control design, we reviewed the records of 7 patients with autosomal dominant polycystic kidney disease from a total of 701 renal transplant patients over a 30-year period (1986-2016).

Outcome of Renal Transplant in Recipients With Vasculitis.

Objectives: End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center.
