Muscle protein turnover and low-protein diets in patients with chronic kidney disease
No full textAdaptation to a low-protein diet (LPD) involves a reduction in the rate of amino acid (AA) flux and oxidation, leading to more efficient use of dietary AA and reduced ureagenesis. Of note, the concept of 'adaptation' to low-protein intakes has been separated from the concept of 'accommodation', the latter term implying a decrease in protein synthesis, with development of wasting, when dietary protein intake becomes inadequate, i.e. beyond the limits of the adaptive mechanisms. Acidosis, insulin resistance and inflammation are recognized mechanisms that can increase protein degradation and can impair the ability to activate an adaptive response when an LPD is prescribed in a chronic kidney disease (CKD) patient. Current evidence shows that, in the short term, clinically stable patients with CKD Stages 3-5 can efficiently adapt their muscle protein turnover to an LPD containing 0.55-0.6 g protein/kg or a supplemented very-low-protein diet (VLPD) by decreasing muscle protein degradation and increasing the efficiency of muscle protein turnover. Recent long-term randomized clinical trials on supplemented VLPDs in patients with CKD have shown a very good safety profile, suggesting that observations shown by short-term studies on muscle protein turnover can be extrapolated to the long-term period
Kidney Transplantation in a Patient Affected by Sickle Cell Trait: A Case Report and State-of-the-Art Review
No full textChronic kidney disease (CKD) is a common feature of sickle cell disease (SCD). The awareness of the clinical presentation and renal involvement in patients affected by hemoglobinopathies is greatly needed. Patient management is particularly complex, especially with kidney transplantation. We, therefore, report the case of a 56-year-old patient affected by sickle cell trait who underwent kidney transplantation. This case will underline all the various challenges the nephrologist must face in this clinical setting and their management

No full textHyperkalemia-induced acute flaccid paralysis: a case report
No full textAcute flaccid paralysis is a medical emergency that may be caused by primary neuro-muscular disorders, metabolic alterations, and iatrogenic effects. Severe hyperkalemia is also a potential cause, especially in elderly patients with impaired renal function. Early diagnosis is essential for appropriate management. Here, we report the case of a 78-year-old woman with hypertension and diabetes presenting to the emergency department because of pronounced asthenia, rapidly evolving in quadriparesis. Laboratory examinations showed severe hyperkalemia of 9.9 mmol/L, metabolic acidosis, kidney failure (creatinine 1.6 mg/dl), and hyperglycemia (501 mg/dl). The electrocardiography showed absent P-wave, widening QRS, and tall T-waves. The patient was immediately treated with medical therapy and a hemodialysis session, presenting a rapid resolution of electrocardiographic and neurological abnormalities. This case offers the opportunity to discuss the pathogenesis, the clinical presentation, and the management of hyperkalemia-induced acute flaccid paralysis
