  Purpose

Bacterial meningitis is a severe infection of the envelope which surrounds the brain. It is sometimes responsible for a cerebral oedema mattering with a loss of consciousness (coma). The usual treatment of this affection is based on the antibiotic therapy, anti-inflammatory drug and resuscitation measures in intensive care setting but the prognosis of comatose patients remains poor.

Moderate hypothermia (body temperature is downed between 32 and 34°C°) made the proof of its efficiency in certain cerebral pathologies (notably the cerebral distress after cardiac arrest or oxygen lack in neonates) but was never evaluated in meningitis. In meningitis animal studies and in severe traumatic brain injury, moderate hypothermia is able to diminish cerebral oedema and brain inflammation.

Thus, the objective of this study is to compare two strategies: only usual care or usual care completed by moderate hypothermia. The body temperature will be lowered between 32 and 34°C by means of a catheter placed in a big vein and connected to a machine in which circulates a cold liquid, or by means of an external cooling (ice-cold blanket, ice packs placed on the body). Whatever technique is chosen, the technique is perfectly mastered by the teams which take charge of the patients. After 48 hours, the technique of hypothermia will be suspended and body temperature will return passively and gradually to normal.

The investigators believe that moderate hypothermia will improve the prognosis of the most severe patients.

Arms Assigned Interventions
Experimental: Hypothermia
mild induced hypothermia (32-34°C) during 48 hours followed by passive rewarming
Procedure: Mild induced hypothermia (32-34°C)

Mild Induced hypothermia:

Investigators are advised to use the cooling techniques as used in patients with cardiac arrest. Thus, the choice of cooling method will be left to investigators. Hypothermia will be induced by cold saline infusion as described in appendix 5 [6, 48]. Core temperature will be monitored by oesophageal probe and maintained between 32°C and 34°C during 48 hours and followed by strictly passive rewarming. During this phase of treatment, patients will receive deep sedation associated with neuromuscular blockers. Centers participating to the trial will have expertise in cooling methods.

Other Name: Mild induced hypothermia (32-34°C)
Active Comparator: No hypothermia
no hypothermia, according to local recommendations and guidelines of medical societies and literature
Procedure: local recommendations and guidelines

Investigational procedure:

This study evaluates the impact of mild induced hypothermia (32-34°C) during 48 hours followed by passive rewarming according to recommendations described in appendix. All treatment will be according to local recommendations and guidelines of medical societies and literature. Physicians are advised to use these recommendations; however, the best treatment option for the individual patient should be used.

Controls will receive standard care and will be also be deeply sedated for 48 hours.
