ReviewAnaemia of critical illness-- implications for understanding and treating rHuEPO resistance.
The prospect of a shortage of blood for transfusions, increasing awareness of the adverse effects of transfusions, and the availability of human recombinant erythropoietin (rHuEPO) have stimulated interest in the pathogenesis of the anaemia of intensive care unit (ICU) patients. As in the anaemia of chronic illness or chronic renal failure (CRF), the anaemia of ICU patients is a multifactorial process. Blood loss, inappropriately low erythropoietin production, reduced red cell lifespan, reduced iron availability, and inhibition of erythropoiesis by cytokines all contribute to the anaemia of critical illness, although the contributions of the various elements differ depending on the disease aetiology. ⋯ Available data suggest that these high doses are well tolerated, at least in the short term. These observations, as well as demonstrating the potential benefits of rHuEPO therapy in critically ill patients, have practical implications for non-ICU patients with CRF who do not respond sufficiently to the usual doses of rHuEPO. Although the risk-benefit ratio relationship for very high doses of rHuEPO needs further consideration, demonstration of rHuEPO efficacy in critical illness should result in a re-evaluation of the 'dose-response relationship' for rHuEPO in patients with less acute and severe illness, including CRF patients hyporesponsive to current dosing regimens.

An overview of morbidity and mortality in patients with acute renal failure due to crush syndrome: the Marmara earthquake experience.
On August 17, 1999 a major earthquake hit the most densely populated area at the eastern end of the Marmara Sea in northwestern Turkey. The number of documented cases of acute renal failure (ARF) following this event exceeded all similar cases previously reported for any single earthquake. The aim of this report was to provide an overview of the morbidity and mortality of all documented patients with ARF, due to crush injury, that were treated in hospitals with dialysis units following the Marmara earthquake. ⋯ We conclude that in cases of severe disasters such as major earthquakes, patients should be rapidly transferred to undamaged peripheral general hospitals. When proper dialysis and intensive care facilities together with around the clock dedicated human effort are available, crush injury-related ARF patients have a lower mortality. Mortality, when it occurs, is mainly associated with thoracic and abdominal trauma and medical problems such as DIC and/or ARDS/respiratory failure, often in conjunction with sepsis.

alpha-MSH decreases apoptosis in ischaemic acute renal failure in rats: possible mechanism of this beneficial effect.
Apoptosis frequently occurs in acute renal injury but the molecular mechanisms responsible for this distinct form of cell death are largely unknown. Fas belongs to the tumour necrosis factor (TNF)/nerve growth factor superfamily and engagement by Fas ligand induces apoptosis in various epithelial cells. To investigate the role of apoptosis and associated mechanisms, we examined the occurrence of apoptosis and Fas and Fas ligand expression, and the therapeutic effect of alpha-melanocyte-stimulating hormone (alpha-MSH), a potent anti-inflammatory cytokine in an ischaemic acute renal failure (ARF) rat model. We also examined neutrophil infiltration together with intercellular adhesion molecule-1 (ICAM-1) expression because of their possible involvement in apoptosis due to their ability to release various inflammatory cytokines and reactive oxygen species. ⋯ These results suggest that apoptosis clearly contributes to tubular cell loss in ischaemia/reperfusion (I/R) injury possibly by neutrophil-mediated pathways or an increase in Fas-Fas ligand expression. The observed beneficial effect of alpha-MSH could be related to these mechanisms.
