Enzyme replacement therapy with agalsidase beta in kidney transplant patients with Fabry disease: a pilot study.
We sought to assess the safety and efficacy of enzyme replacement therapy (ERT) with recombinant human-alpha-galactosidase A (rh-alpha-Gal A) in kidney transplant recipients with Fabry disease, a previously unstudied population. ⋯ Our pilot study provides preliminary evidence that ERT with agalsidase beta, 1 mg/kg every 2 weeks, is safe and often effective against extra-renal manifestations in kidney transplant patients with Fabry disease. Studies with longer courses of this and higher doses of ERT are merited in this population.

Multicenter StudyPlasma cytokine levels predict mortality in patients with acute renal failure.
Critically ill patients with acute renal failure (ARF) experience a high mortality rate. Animal and human studies suggest that proinflammatory cytokines lead to the development of a systemic inflammatory response syndrome (SIRS), which is temporally followed by a counter anti-inflammatory response syndrome (CARS). This process has not been specifically described in critically ill patients with ARF. ⋯ There is evidence of ongoing SIRS with concomitant CARS in critically ill patients with ARF, with higher levels of plasma IL-6, IL-8, and IL-10 in patients with ARF who die during hospitalization. Strategies to modulate inflammation must take into account the complex cytokine biology in patients with established ARF.

Cytokine gene polymorphisms in hemodialysis patients: association with comorbidity, functionality, and serum albumin.
Cytokine-orchestrated chronic inflammation plays a major role in long-term morbidity and mortality in patients with end-stage renal disease (ESRD) on hemodialysis (HD). In this cross-sectional study, we evaluated the association between specific alleles/genotypes and combinations of genotypes of interleukin (IL)-6, tumor necrosis factor-alpha (TNF-alpha), and IL-10 with indices of comorbidity, functional status, and other biological markers in a cohort of 183 ESRD patients recruited to the Hemodialysis (HEMO) Study from two Boston centers. ⋯ In ESRD patients on long-term HD, single nucleotide polymorphisms in the promoter region of the proinflammatory cytokines IL-6 and TNF-alpha, and the regulatory monokine IL-10, show a strong association with indices of comorbidity and function, and biological and nutritional markers.

In vivo transfection of NF-kappaB decoy oligodeoxynucleotides attenuate renal ischemia/reperfusion injury in rats.
Ischemic acute renal failure (ARF) is a common and often fatal condition characterized by tubular epithelial cell necrosis and marked monocyte infiltration. Inflammatory mechanisms, including cell adhesion, cell infiltration, and cytokine production, are involved. These processes are thought to be directly or indirectly regulated by nuclear factor kappaB (NF-kappaB). Targeted of NF-kappaB might ameliorate ischemia/reperfusion (I/R) injury by inhibiting the production of genes that involved in ischemic ARF. The objective of the present study was to evaluate the effect of NF-kappaB decoy oligodeoxynucleotides (ODN) in experimental rat ischemic ARF. ⋯ These experiments demonstrated that NF-kappaB plays a critical role in renal I/R injury by reducing a series of inflammatory genes. NF-kappaB decoy ODN treatment reduces the renal dysfunction and damage associated with ischemic ARF. Therefore, in vivo transfection of NF-kappaB decoy ODN provides a new therapeutic strategy for ischemic ARF.
