Low High
Final diagnosis• Human rabies complicated with deep coma status and multiple
organs failure (respiratory failure, central failure, pan-hypopituitarism)
• Staphylococcus hominis bacteremia with septic shock, including acute respiratory failure status post tracheostomy with ventilator support.
• Rhabdomyolysis with acute renal failure, complicated with end-stage renal disease status post hemodialysis, improving.
• CMV reactivation.• Healthcare associated pneumonia, bilateral
Discussion
• Rabies post-exposure prophylaxis, which is highly effective if given promptly, includes: – wound cleansing,– immunization with a modern cell culture vaccine, – and administration of human rabies immunoglobulin (HRIG)
• Once rabies encephalitis develops, no therapy has proved effective.
CID 2003:36 (1 January) • Jackson et al.
Aggressive or Palliative approach to Therapy
• For previously unvaccinated patients with rabies, reports to date have indicated agonizing symptoms and a 100% mortality rate.
• Aggressive approach to therapy with the aim of curing the disease: even if such an approach were successful, the patient likely would be left with permanent disabling neurological deficits.
CID 2003:36 (1 January) • Jackson et al.
Making the decision to embark on an aggressive course of therapy:1. Administration of any rabies vaccine before the onset of clinical
rabies.2. Presentation with a very early stage of disease, including
paresthesias or pain at the site of a previous bite exposure, with minimal other neurological symptoms or signs.
3. Good health and absence of chronic disease.4. Relatives who accept both the high probability of an
unsuccessful outcome and the possibility of disabling neurological deficits in a rabies survivor
Aggressive or Palliative approach to Therapy
CID 2003:36 (1 January) • Jackson et al.
Specific Therapies• Rabies vaccine
– Human rabies vaccines are inactivated and do not elicit a cytotoxic T cell response.
– No human live attenuated or recombinant rabies vaccine has been licensed for use in humans to date.
• Rabies immunoglobulin(20 IU/kg) : in rabies post-exposure prophylaxis, HRIG neutralizes the virus before its invasion of the nervous system.
• Corticosteroids: Corticosteroid therapy generally is not considered for the management of brain edema in rabies – In mouse models, administration of corticosteroids increased the
mortality rate and shortened the incubation period. Can J Microbiol 1970; 16:667–75.
CID 2003:36 (1 January) • Jackson et al.
Milwaukee_rabies_protocol_V3_1
Milwaukee_rabies_protocol_V3_1What to do first: • DO NOT administer rabies vaccine or
immunoglobulin. • This has never worked in rabid patients. • It violates a key assumption of the Milwaukee protocol. • It may cause “early death” phenomena, based on case
reports and animal models.
Differential diagnosis• Rabies is NOT likely in patients:
– Without a fever – With an illness lasting more than 14 days (other
than Guillain-Barre-like syndrome) – With an incubation period following an animal
bite or transplantation of < 10 days or > 1 year – Who completed a full course of rabies post-
exposure prophylaxis including immune globulin
Once rabies is considered • Isolate the patient• Minimize early demise in 20% of patients from
catecholamine storm or bradyarrythmia/asystole – If patient is extremely agitated, hypertensive, with
tachyarrhythmia, consider diagnosis of CNS- mediated catecholamine storm. This may cause cardiomyopathy if untreated. Bradyarrhythmias and asystole are also common.
•
• Minimize stimulation – similar to management of tetanus.
• Use heavy sedation (preferably midazolam ± fentanyl) x 24 h. Avoid barbiturates – these inhibit the immune response. – Propofol has a relative contraindication
Once rabies is considered
Rabies vaccinePre-exposure• 3 doses administered on Day 0, 7, and 21 (or 28 day). • Injected site deltoid muscle, never gluteal
muscle. MMWR 2010;59:RR-2
Post exposure prophylaxis• 5 doses administered on Day 0, 3,7, and 14 and 28 day.
Are we ready to care Rabies ?• Hospitals or clinics
– Standard precaution– Wound cleaning techniques (soap 10-15 min +
70-75% alcohol wound care reduce 90% risk of rabies)
– What kind of patients need vaccination
• Healthcare workers– Contact isolation (body fluid isolation)– Face mask, eye glasses, gloves, gowns– Post-exposure prophylaxis procedures
• Educate patient’s families
