Caring for super obese patients (body mass index > 50 kg/m(2)) presents a number of complex and unique clinical challenges, particularly when acute kidney injury is present. We describe our experience treating the heaviest individual with acute kidney injury requiring renal replacement therapy reported to date. ⋯ During hospitalization, the patient experienced oligoanuric acute kidney injury and required initiation of continuous and subsequently intermittent renal replacement therapy. This clinical scenario identifies the many challenges involved in caring for super obese patients with acute kidney injury and may be a harbinger of what awaits the nephrology community in the obesity pandemic era.

Anxiety is a complicating comorbid diagnosis in many patients with medical illnesses. In patients with end-stage renal disease (ESRD), anxiety disorders often are perceived to represent symptoms of depression rather than independent conditions and therefore have been relatively understudied in this medical population. ⋯ A substantial proportion of participating patients met criteria for an anxiety disorder. The utility of the HADS as a screening tool for anxiety in patients with ESRD should be questioned. The finding that anxiety disorders negatively impact on QOL and are not merely manifestations of depression in patients with ESRD emphasizes the importance of accurate diagnosis and effective treatment. Strategic options are necessary to improve the diagnosis of anxiety disorders, potentially enhancing QOL and medical outcome in patients with ESRD.

The role of obesity as a risk factor for cardiovascular disease in patients with chronic kidney disease (CKD) is poorly understood. Waist-to-hip ratio (WHR) is less influenced by muscle and bone mass than body mass index (BMI). We compared WHR and BMI as risk factors for cardiac events (myocardial infarction and fatal coronary disease) in persons with CKD. ⋯ WHR, but not BMI, is associated with cardiac events in persons with CKD. Relying exclusively on BMI may underestimate the importance of obesity as a cardiovascular disease risk factor in persons with CKD.
