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. Methodology. We report the experiences of two nephrology centers in Tunis with ATDC as an ultimate vascular access for dialysis. Case Reports. Two patients with exhausted vasculature underwent ATDC insertion in 2020 and 2022, respectively, as a vascular access of last resort. Both patients underwent CRBI, which resolved with favorable outcomes. One case was complicated by post-operative thrombosis and was successfully treated with thrombolysis. Both patients are currently on dialysis via their ATDC with a catheter patency of 29 months. Conclusion. ATDC is a life-saving and safe vascular access in cases of depleted vasculature. Little more than 50 cases have been reported in the literature during the last 30 years. As the frequency of vasculature exhaustion is expected to increase, preservation of veinous access in patients at risk of chronic kidney disease have never been more crucial. [ABSTRACT FROM AUTHOR]

Drug‐induced tubulointerstitial nephritis is an uncommon complication in patients on anti‐tuberculosis therapy that can lead to permanent kidney damage. Rifampicin is the most offending drug. We report a case of a 41‐years old man being treated for pulmonary tuberculosis and presenting with tubulointerstitial nephritis associated with rifampicin. We focus on diagnosis features and therapeutic challenges. [ABSTRACT FROM AUTHOR]

Multiple myeloma (MM) results from malignant plasma cell disorder. It represents approximately 10% of hematological malignancies and it is typically diagnosed in the elderly with a median age of 70 years and has a steep increase in incidence with advancing age. N Engl J Med. 2004, 1860; Clin Interv Aging. 2020, 619. The incidence of MM has been increasing over time, mostly due to population aging. Mayo Clin Proc. 2010, 225 However, certain MMs are diagnosed at young age even under 40 years old (2%). Leuk Lymphoma. 1998, 493; Blood. 2010, 5501. We report a case of a MM in a thirty‐four‐year‐old woman whose circumstance of discovery was acute kidney failure. [ABSTRACT FROM AUTHOR]
