The Marmara earthquake: admission laboratory features of patients with nephrological problems.
Earthquakes are major causes of morbidity and mortality. North-western Turkey was struck by a devastating earthquake in August 1999, which caused several thousand deaths. Among the most important morbid events in survivors were acute nephrological problems. ⋯ Admission laboratory data may be useful for predicting dialysis needs and survival chance of disaster victims. High incidences of some life-threatening abnormalities dictate the need for empirical therapy even in the field.

Circulating levels of ICAM-1, VCAM-1, and MCP-1 are increased in haemodialysis patients: association with inflammation, dyslipidaemia, and vascular events.
Increased levels of circulating adhesion molecules and chemokines have been reported in haemodialysis (HD) patients but the influence of the HD membranes on their secretion, as well as their pathophysiological implications, remains largely unknown. ⋯ Serum levels of ICAM-1, VCAM-1, and MCP-1 are increased in HD patients and probably result from either inadequate clearance or enhanced synthesis and release. HD session resulted in a significant increase of the above molecule levels but the exact mechanism(s) responsible for these alterations are yet to be fully elucidated. Increased levels of adhesion molecules are associated with inflammation, dyslipidaemia, and cardiovascular events. However, the potential link between these processes and its clinical significance warrants further investigation.

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.
