PD vs HD in Post-Economic Crisis Greece-Differences in Patient Characteristics and Estimation of Therapy Cost.

Objective: The aim of this study was to investigate patient characteristics and make an estimation of the cost of peritoneal dialysis (PD) and hemodialysis (HD) to Greek society during the economic crisis.

Methods: We recorded the characteristics and the total cost of dialysis treatment in 100 patients on PD and 100 on HD. Total costs included dialysis procedure, consumables, drugs, laboratory tests, food, and transportation fees (only HD), covered by patients' insurance.

Periodic therapeutic plasma exchange in patients with moderate to severe chronic myasthenia gravis non-responsive to immunosuppressive agents: an eight year follow-up.

Few patients with moderate or severe myasthenia gravis (MG) do not respond to immunosuppressive treatment. We present our experience with periodic therapeutic plasma exchange (TPE), in 11 patients with MG resistant to intravenous immunoglobulin (IVIg) therapy, who had frequent relapses even whilst on high doses of immunosuppressive drugs, over a period of 8 years. All patients underwent TPE until control of their symptoms was achieved, and afterwards TPE sessions were continued periodically in an attempt to achieve remission of the disease, without immunosuppressant therapy.

The effect of sexual hormone abnormalities on proximal femur bone mineral density in hemodialysis patients and the possible role of RANKL.

Sexual hormone concentrations are commonly affected in chronic renal failure. The contribution of sex steroids to bone turnover regulation implies that sex steroid's dysfunction may be implicated in the emergence of renal osteodystrophy. This study was conducted to evaluate sex steroids and gonadotrophins in hemodialysis (HD) patients and to investigate their role in bone homeostasis in concert with other hormones and cytokines.
