inositol and Brain Edema

inositol has been researched along with Brain Edema in 14 studies

Inositol: An isomer of glucose that has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379) Inositol phospholipids are important in signal transduction.
inositol : Any cyclohexane-1,2,3,4,5,6-hexol.
1D-chiro-inositol : Belonging to the inositol family of compounds, D-chiro-inositol (DCI) is an isomer of glucose. It is an important secondary messenger in insulin signal transduction.
muco-inositol : An inositol that is cyclohexane-1,2,3,4,5,6-hexol having a (1R,2R,3r,4R,5S,6r)-configuration.

Brain Edema: Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)

Trial Outcomes

Change in Ammonia

To evaluate the effect of OCR-002 on ammonia levels in patients with acute liver failure/severe acute liver injury (NCT01548690)
Timeframe: Baseline and 72 Hours

InterventionPercent Change (Mean)
Maximum Dose Level 3.33 g/24h41.2
Maximum Dose Level 6.65 g/24h16.6
Maximum Dose Level 10 g/24h41.8
Maximum Dose Level 20g/24h38.4

Measurement of OCR-002 Plasma Concentration

To evaluate the steady state pharmacokinetic and pharmacodynamic profile of OCR-002 in patients with impaired and intact renal function using urinary phenylacetylglutamine (PAGN) as a surrogate marker (NCT01548690)
Timeframe: 24 Hours after last infusion

Interventionmicrograms per millileter (Mean)
Maximum Dose Level 3.33 g/24h65.6
Maximum Dose Level 6.65 g/24h32.2
Maximum Dose Level 10 g/24h33.4
Maximum Dose Level 20g/24h104.9

Neurological Function Measured by the Orientation Log (O-log)

The orientation log focuses on orientation to place, time, and circumstance. There are 10 items on the orientation log, which are scored 0-3. A spontaneous correct response is awarded 3 points. A spontaneous response that is lacking or incorrect, but a correct response is provided following a logical cue is awarded 2 points. A score of 1 is given if spontaneous and cued responses are lacking or incorrect, but a correct response is provided in a recognition format. A score of 0 is given if the spontaneous, cued, or recognition format does not generate a correct answer. Scores from the 10 items are summed and the final score ranges from 0 to 30. (NCT01548690)
Timeframe: 30 Days

Interventionunits on a scale (Mean)
Maximum Dose Level 3.33 g/24h23.8
Maximum Dose Level 6.65 g/24h24.0

Maximum Dose Level 20g/24h24.0

Neurological Function Measured by the West Haven Criteria (WHC) for Hepatic Encephalopathy

The West Haven Criteria (WHC) for Hepatic Encephalopathy measures the severity of encephalopathy and patient's level of consciousness. The scale ranges from 0 to 4; a minimum score of 0 represents a better outcome, and a maximum total score of 4 represents a worse outcome. A score of 0 corresponds to normal consciousness and behavior and normal neurological examination. A score of 1 corresponds to mild lack of awareness, shortened attention span, and impaired addition or subtraction; mild asterixis or tremor. A score of 2 corresponds to lethargy, disorientated or inappropriate behavior, obvious asterixis; slurred speech. A score of 3 corresponds to somnolent but arousable, gross disorientation or bizarre behavior, muscle rigidity and clonus; hyperreflexia. A score of 4 corresponds to coma and decerebrate posturing. (NCT01548690)
