Endogenous testosterone, muscle strength, and fat-free mass in men with chronic kidney disease.

Objective: Testosterone deficiency is a common finding in men with chronic kidney disease (CKD). Testosterone is thought to play an important anabolic role in muscle synthesis, and muscle wasting is an important and deleterious characteristic of protein-energy wasting (PEW) in CKD. It is presently unknown if reduced endogenous testosterone associates with features of muscle wasting in men with CKD.

Plasmapheresis in diffuse alveolar hemorrhage as perinuclear antineutrophil cytoplasmic antibody-associated vasculitis relapse on hemodialysis.

Unlike Goodpasture's syndrome with diffuse alveolar hemorrhage (DAH), there are scarce reports on the use of plasmapheresis for patients with a recurrence of DAH associated with antineutrophil cytoplasmic antibody (ANCA)-associated small vessel vasculitis (AAV) on hemodialysis. We report a case of a relapse of perinuclear-AAV with DAH, five months after starting hemodialysis. The patient received apheresis and induction immunosuppressive therapy, added to a short course of daily hemodialysis treatments.
