Friday, September 10th Update. Diagnosis made: GBS

Aidan was admitted to Morristown Memorial Hospital after being taken by ambulance on Tuesday night. He is under sedation, on IV's for nutrition and is on a ventilator to assist him breathing. He is being cared for in the PICU - Pediatric Intensive Care Unit.


He was diagnosed with Guillain-Barre Syndrome. For those of you who are not familiar with this, as I think none of us were - here is some information.

Guillain–Barré syndrome (GBS) - is an acute inflammatory demyelinating polyneuropathy (AIDP), an autoimmune disorder affecting the peripheral nervous system, usually triggered by an acute infectious process. The syndrome was named after the French physicians Guillain, Barré and Strohl, who were the first to describe it in 1916. It is sometimes called Landry's paralysis, after the French physician who first described a variant of it in 1859. It is included in the wider group of peripheral neuropathies. There are several types of GBS, but unless otherwise stated, GBS refers to the most common form, AIDP. GBS is rare and has an incidence of 1 or 2 people per 100,000. It is frequently severe and usually exhibits as an ascending paralysis noted by weakness in the legs that spreads to the upper limbs and the face along with complete loss of deep tendon reflexes. With prompt treatment by plasmapheresis or intravenous immunoglobulins and supportive care, the majority of patients will regain full functional capacity. However, death may occur if severe pulmonary complications and autonomic nervous system problems are present. Guillain-Barré is one of the leading causes of non-trauma-induced paralysis in the world.

He is starting IV therapy today and they expect for him to be in the hospital for approximately 2 weeks.

Management of GBS

Supportive care with monitoring of all vital functions is the cornerstone of successful management in the acute patient. Of greatest concern is respiratory failure due to paralysis of the diaphragm. Early intubation should be considered in any patient with a vital capacity (VC) <20 ml/kg, a negative inspiratory force (NIF) <-25 cmH2O, more than 30% decrease in either VC or NIF within 24 hours, rapid progression of disorder, or autonomic instability.

Once the patient is stabilized, treatment of the underlying condition should be initiated as soon as possible. Either high-dose intravenous immunoglobulins (IVIg) at 400 mg/kg for 5 days or plasmapheresis can be administered, as they are equally effective and a combination of the two is not significantly better than either alone. Therapy is no longer effective two weeks after the first motor symptoms appear, so treatment should be instituted as soon as possible. IVIg is usually used first because of its ease of administration and safety profile, with a total of five daily infusions for a total dose of 2 g/kg body weight (400 mg/kg each day). The use of intravenous immunoglobulins is not without risk, occasionally causing hepatitis, or in rare cases, renal failure if used for longer than five days. Glucocorticoids have not been found to be effective in GBS. If plasmapheresis is chosen, a dose of 40-50 mL/kg plasma exchange (PE) can be administered four times over a week.

Following the acute phase, the patient may also need rehabilitation to regain lost functions. This treatment will focus on improving ADL (activities of daily living) functions such as brushing teeth, washing, and getting dressed. Depending on the local structuring on health care, a team of different therapists and nurses will be established according to patient needs. An occupational therapist can offer equipment (such as wheelchair and special cutlery) to help the patient achieve ADL independence. A physiotherapist would plan a progressive training program and guide the patient to correct, functional movement, avoiding harmful compensations which might have a negative effect in the long run. A speech and language therapist would be essential in the patient regaining speaking and swallowing ability if they were intubated and received a tracheostomy. The speech and language therapist would also offer advice to the medical team regarding the swallowing abilities of the patient and would help the patient regain their communication ability pre-dysarthria. There would also be a doctor, nurse and other team members involved, depending on the needs of the patient. This team contributes their knowledge to guide the patient towards his or her goals, and it is important that all goals set by the separate team members are relevant for the patient's own priorities. After rehabilitation the patient should be able to function in his or her own home and attend necessary training as needed.
Prognosis

Most of the time recovery starts after the fourth week from the onset of the disorder. Approximately 80% of patients have a complete recovery within a few months to a year, although minor findings may persist, such as areflexia. About 5–10% recovers with severe disability, with most of such cases involving severe proximal motor and sensory axonal damage with inability of axonal regeneration. However, this is a grave disorder and despite all improvements in treatment and supportive care, the death rate among patients with this disorder is still about 2–3% even in the best intensive care units. Worldwide, the death rate runs slightly higher (4%), mostly from a lack of availability of life support equipment during the lengthy plateau lasting four to six weeks, and in some cases up to one year, when a ventilator is needed in the worst cases. About 5–10% of patients have one or more late relapses, in which case they are then classified as having chronic inflammatory demyelinating polyneuropathy (CIDP).

Kim and George are available via text or just call. You are not bothering them, they need the support, and if they're busy they just won't answer or respond immediately.

I will update this often so everyone can stay informed - check back regularly and thanks for your support.
