Summary Summary

PANDAS is an acronym for Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus. It is used to describe a condition in children whose symptoms of obsessive-compulsive disorder (OCD) or a tic disorder (i.e. Tourette syndrome) are worsened by group A streptococcal (GAS) infections. The underlying cause of PANDAS is unclear, but studies suggest that a strep infection causes an abnormal immune response resulting in neuropsychiatric symptoms. The association between PANDAS and GAS is controversial because the cause has not been proven. Management is centered on providing antibiotics for GAS infection, and medication or behavioral therapy for neuropsychiatric symptoms.^[1]^[2]

Symptoms Symptoms

PANDAS is an acronym for Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus. It describes the abrupt onset or worsening of symptoms in children who have obsessive-compulsive disorder or a tic disorder (i.e. Tourette syndrome), following a group A streptococcal infection (strep infection). Following a strep infection, children affected by PANDAS typically experience a sudden onset of motor or vocal tics; obsessions; and/or compulsions. These severe symptoms typically last from several weeks to several months. After a gradual improvement, children may not experience any additional problems until they contract another strep infection.^[3]^[4]^[5]

Children may also experience the following signs and symptoms during a PANDAS episode:^[3]^[5]

Moodiness and irritability
Separation anxiety
ADHD symptoms
Sleep disturbances
Night-time bed wetting and/or day-time urinary frequency
Fine motor changes (handwriting)
Joint pain
Concentration difficulties and loss of academic abilities
Developmental regression (i.e. temper tantrums, "baby talk")

Cause Cause

Although the exact underlying cause of PANDAS has not been proven, studies suggest that it may be an autoimmune disorder. Normally, when a person is exposed to bacteria, the immune system makes proteins called antibodies to fight off the infection. In autoimmune disorders, the body's immune system mistakenly attacks and destroys its own, healthy body tissue.^[6] PANDAS may occur when a group A streptococcal infection (strep infection) triggers an abnormal immune response, causing the body to mistakenly attack the tissues of the central nervous system (brain and spinal cord).^[6] However, the role of autoimmunity in PANDAS is controversial.^[1]

Diagnosis Diagnosis

A diagnosis of PANDAS is based on the presence of the following:^[4]^[6]

Obsessive-compulsive disorder or a tic disorder (i.e. Tourette syndrome)
Symptoms develop before age 12
Abrupt onset of symptoms and "episodic" course (relapses are separated by periods of time in which children have less severe or no symptoms)
Association with group A streptococcal infection (in some cases, the affected person has no obvious symptoms of a strep infection; however, a throat culture and/or blood tests may show evidence of a current or recent infection)
Association with other neuropsychiatric symptoms (i.e. separation anxiety, ADHD, developmental regression, etc)

There are currently no tests available to confirm a diagnosis of PANDAS.

Treatment Treatment

The treatment of PANDAS is symptomatic. Children who are diagnosed with a group A streptococcal infection are typically treated with antibiotics whether or not they develop symptoms of PANDAS. Obsessive-compulsive disorders are usually managed with medications (i.e. SSRI medications such as fluoxetine, fluvoxamine, sertaline, or paroxetine) and cognitive behavioral therapy. Tic disorders are often treated with a variety of medications, as well.^[4]^[5]

Some researchers suspect that therapies such as plasmapheresis and/or intravenous immunoglobulin (IVIG), which are often used to treat autoimmune disorders, may be a treatment option for children with PANDAS. Plasmapheresis is a procedure that removes antibodies from the blood. IVIG can sometimes be used to alter the function or production of abnormal antibodies. Although some studies have demonstrated that both of these therapies are effective for the treatment of severe, strep triggered OCD and tics, a number of the children in these studies experienced severe side-effects. Thus, these treatments are often reserved for severely affected children who do not respond to other therapies.^[4]^[5]

Statistics Statistics

The incidence and prevalence of PANDAS are not known, although it is rare. In one prospective study, only 10 cases were identified among 30,000 throat cultures (1 in 3000) positive for group A streptococci (GAS). Since then, the annual incidence has ranged between 0 per 10,000 cultures to 10 per 30,000 cultures, depending upon the strain of GAS and other factors. Despite its rarity, some researchers suggest that it may account for ≥10% of childhood-onset obsessive-compulsive disorder (OCD) and tic disorders.^[1]

I have three children who have been treated for PANDAS and PANS successfully, on several occasions. I am a nursing student and for my research paper, I chose to write about PANDAS because I am passionate about the subject, having faced tremendous difficulty in getting help for my children. I am wondering if you know about the prevalence and incidence of PANDAS, as I am not able to find much information about how many children are affected. I appreciate any help you can give me.
