As kidney disease progresses, patients often experience a variety of symptoms. A challenge for the nephrologist is to help determine if these symptoms are related to advancing CKD or the effect of various comorbidities and/or medications prescribed. The clinician also must decide the timing of dialysis initiation. The initiation of dialysis can have a variable effect on quality of life measures and the alleviation of uremic signs and symptoms, such as anorexia, fatigue, cognitive impairment, depressive symptoms, pruritus, and sleep disturbances. Thus, the initiation of dialysis should be a shared decision-making process among the patient, the family and the nephrology team; information should be provided, in an ongoing dialogue, to patients and their families concerning the benefits, risks, and effect of dialysis therapies on their lives.

The Simpson atherectomy catheter has been used successfully to recanalise eleven complete occlusions of the iliac and femoropopliteal arteries. Atherectomy and angioplasty were used in combination in 8 cases. Following atherectomy, all patients showed clinical improvement. Distal pulses returned in 7; rest pain and/or claudication disappeared in the other 4. Ischaemic ulcers healed in the 2 affected patients. Overall, ankle-arm indices (AAI) improved by an average of 0.43, with the improvement being greatest (0.55) in patients in whom the lumen was recanalised to within 91-100% of the native luminal diameter. Seven patients have remained with stable AAI values and without change in their clinical status at 18 months follow-up.

Extracorporeal modalities for the removal of drugs and toxins are indicated for the treatment of overdoses and intoxications. Well-established modalities include hemodialysis (HD), high-flux HD (HfD), and charcoal hemoperfusion (HP). Recently, there have been increasing reports on the use of continuous renal replacement therapy (CRRT), such as continuous veno-venous hemodialysis (CVVHD), continuous veno-venous hemofiltration (CVVH) or CVVH combined with dialysis (CVVHDF). In the present article, we will discuss the various factors that determine the clearance of drugs and toxins and accordingly, we will propose that with few exceptions, CRRT does not have a role in the routine management of intoxications.
