Roadmaps to green nephrology: a mediterranean point of view.

Purpose Of Review: Green nephrology is a movement whose aim is to find ways to reduce the environmental impact of kidney care. The question is of particular concern in this field since haemodialysis is one of the major contributors to waste generation, energy use and water consumption in healthcare. Although several ways for improving sustainability have been advocated, they are all context sensitive.

Water implications in dialysis therapy, threats and opportunities to reduce water consumption: a call for the planet.

Water is a dwindling natural resource, and potable water is wrongly considered an unlimited resource. Dialysis, particularly hemodialysis, is a water-hungry treatment that impacts the environment. The global annual water use of hemodialysis is approximately 265 million m/yr.

The presence of two light chain bands on immunofixation is associated with poor outcomes in newly diagnosed multiple myeloma patients.

We aimed to describe the clinical and biological characteristics and the prognosis of patients presenting with an additional light chain (LC) band along with a complete monoclonal protein on immunofixation (IF).An 8-year descriptive study was conducted to assess all cases with confirmed monoclonal gammopathies (MG). We studied those with an entire M-protein with 2 bands of LC of the same isotype based on the results of IF.

Melatonin intake before intradialytic exercise reverses oxidative stress and improves antioxidant status in hemodialysis patients.

Purpose: The present study aimed to investigate for the first time the effects of melatonin (MEL) intake on oxidative stress and cellular damage during intradialytic exercise (IEX).

Biclonal Gammopathies in South Tunisia: Clinical and Biological Characteristics.

Objective: Biclonal gammopathies (BGs) are rare situations characterized by the production of 2 monoclonal proteins. There are no available data on BGs in North Africa. We aimed to estimate the prevalence of BGs in our population and describe their clinical and laboratory features.

Effects of intradialytic exercise in combination with melatonin supplementation on functional capacity, postural balance, and quality of life in hemodialysis patients.

Introduction: We evaluated the effect of intradialytic concurrent (resistance-endurance) training combined with melatonin (MEL) supplementation on functional capacity, muscle strength, postural balance, and quality of life (QoL) in hemodialysis (HD) patients.

Methods: Thirty-three HD patients were randomized into three groups: Exercise (EX)-MEL (n = 11); EX-Placebo (PLA) (n = 11) and Control (C)-PLA (n = 11). Participants included in the EX-MEL and EX-PLA groups were submitted to concurrent training for 12 weeks.

Acinetobacter lwoffi peritonitis in peritoneal dialysis: two cases report.

Peritonitis is an important cause of morbidity and technique failure in peritoneal dialysis. Herein, we report peritonitis related to Acinetobacter lwoffi in two patients on peritoneal dialysis. The first case is a 63-year-old patient treated by automated peritoneal dialysis admitted with abdominal pain.

Chronic Kidney Disease, Hypokalemia, and Appendicular Mucocele in a 66-Year-Old Man.

Appendicular mucocele (AM) is a rare and potentially malignant entity linked to obstructive dilatation of the appendix with an intraluminal accumulation of mucoid material. Most AM is asymptomatic or simulates acute appendicitis. We report an exceptional case of AM discovered in the face of hypokalemia and aggravation of chronic kidney disease (CKD) without diarrhea in an old man.

Acute kidney injury leading to the diagnosis of sporadic testicular Burkitt's lymphoma: A case report.

• Burkitt’s lymphoma of the testis is extremely aggressive. • The rapid tumor growth of Burkitt’s lymphoma of the testis can be responsible for an important tumoral extension. • Diagnostic delay can lead to an impressive extra gonadal extension of Burkitt’s lymphoma of the testis.

[Cutaneous leishmaniasis after renal transplantation: Report of 7 cases and review of the literature].

Leishmaniasis is a zoonosis acquired from the bite of a sandfly that introduces the amastigote forms of leishmania into the bloodstream. It is a frequent infection in the countries of the Mediterranean basin and in Tunisia, where it is rife in an endemo-epidemic mode. However, it is rare after kidney transplantation.

ePHex: a phase 3, double-blind, placebo-controlled, randomized study to evaluate long-term efficacy and safety of Oxalobacter formigenes in patients with primary hyperoxaluria.

Background: Primary hyperoxalurias (PHs) are rare genetic diseases that increase the endogenous level of oxalate, a waste metabolite excreted predominantly by the kidneys and also the gut. Treatments aim to improve oxalate excretion, or reduce oxalate generation, to prevent kidney function deterioration. Oxalobacter formigenes is an oxalate metabolizing bacterium.

Unusual Cause of Peritonitis in Peritoneal Dialysis Patient Related to Streptococcus salivarius.

Peritonitis remains the most common serious complication associated with peritoneal dialysis (PD). The Gram-positive peritonitis with Staphylococcus aureus and coagulase-negative Staphylococcus are the most frequent causes, whereas Gram-positive and Gram-negative species remain less frequent. We report an uncommon case of PD-related peritonitis due to Streptococcus salivarius, known as nonpathogen Gram-positive bacteria of oral flora.

Bone marrow aspirate: a diagnostic tool for primary hyperoxaluria type 1.

Introduction: Type1 primary hyperoxaluria is an infrequent autosomal recessive metabolic disease characterized by the accumulation of calcium oxalate in the kidney, which leads to end stage renal disease. In fact, the diagnosis of this disease is mandatory in order to avoid graft loss.

Aim: To assess the incidence of primary hyperoxaluria and to develop the diagnostic value of bone marrow infiltration by calcium oxalate in uremic stone former patients.

Primary membranoproliferative glomerulonephritis in Sfax, Tunisia: epidemiologic profile and prognostic factors.

Introduction: membranoproliferative glomerulo nephritis (MPGN) is a rare kidney disease with a poor prognosis as 50% of patients attend the end stage renal failure after 10 years of follow up. Several factors have been described associated with poor renal prognosis. The aim of our study is to determine the epidemiologic profile and to identify prognostic factors of MPGN.

Treatment of chronic hepatitis C with sofosbuvir in a hemodialysis patient: a case report.

The treatment of chronic hepatitis C virus (HCV) infection in chronic hemodialysis patients remains an issue of great concern for nephrologists. In 2008 the kidney disease improving global outcomes working group suggested the use of pegylated interferon in end stage kidney disease patients treated by dialysis. Since then, series and some clinical trials on different direct-acting antiviral agents have shown better efficacy and tolerance than interferon-based regimens.

Next-generation sequencing in patients with familial FSGS: first report of collagen gene mutations in Tunisian patients.

Focal segmental glomerulosclerosis (FSGS) is a histological lesion with many causes, including inherited genetic defects, with significant proteinuria being the predominant clinical finding at presentation. FSGS is considered as a podocyte disease due to the fact that in the majority of patients with FSGS, the lesion results from defects in the podocyte structure. However, FSGS does not result exclusively from podocyte-associated genes.
