Alterations in intracellular calcium during sepsis.

Tissue injury and/or infection produce significant alterations in intracellular calcium ion regulation. These alterations in cellular calcium has recently been studied following both short term and long term septic model which uses two types of gram-negative bacteria frequently encountered human abdominal sepsis. Changes in calcium flux as well as functional disturbances has been observed in the major organs, specially in skeletal muscle. The changes in calcium flux in different organs were studied using 45Ca exchange, 19F NMR study or by using calcium-fluorescence probes. Calcium-channel blockers attenuate the increased effects of calcium flux. Further anti-cytokines may be useful to prevent septic injury in tissues.
