Background

Sandifer syndrome involves spasmodic torsional dystonia with arching of the back and rigid opisthotonic posturing, mainly involving the neck, back, and upper extremities, associated with either gastroesophageal reflux or the presence of hiatal hernia.1

Pediatric neurologists may be the first to see patients with Sandifer syndrome because the primary care provider may believe that the spasms represent seizures. Few case reports of this syndrome are available; however, pediatric emergency department physicians, pediatric neurologists, and gastroenterologists see patients with this complex with some frequency. The syndrome is most likely underrecognized.2

Pathophysiology

The true pathophysiologic mechanisms of this condition remain unclear.

Frequency

International

The incidence is unknown, although some suggestion indicates that in clinical practice it occurs in less than 1% of children with gastroesophageal reflux.

Mortality/Morbidity

Mortality is not typically associated with Sandifer syndrome.

Morbidity consists of the discomfort associated with this syndrome.3 Infants may lose weight if persistent or severe gastroesophageal reflux disease (GERD) is present. Associated morbidities may also include the presence of a hiatal hernia and esophagitis.

Race

Race does not seem to influence incidence.

Sex

No sex predilection is recognized.

Age

Typically, Sandifer syndrome is observed from infancy to early childhood. Peak prevalence is in individuals aged 18-36 months. Children with severe mental impairment or spasticity may experience Sandifer syndrome into adolescence.



History

Sandifer syndrome is most commonly mistaken for seizures. The child typically appears to have an alteration in mental status associated with the tonic posturing.

  • A relationship with feeding may suggest a diagnosis of Sandifer syndrome, which commonly occurs shortly after feeding.
  • The child may have a sudden rotation of the head and neck to one side and the legs to the opposite side with a stretched out appearance. Typically, the back is arched posteriorly with hyperextension of the spine and elbows may be flexed and held posteriorly with hyperextended hips. Torticollis may be present.4 Although the intermittent stiff tonic posture and periods of crying and apparent discomfort may suggest seizures, no rhythmic clonic component, which may be present in seizures, is present.
  • Various stiff, bizarre postures can be observed.
    • Typically, the duration of the posture is 1-3 minutes.
    • This brief, episodic pattern of posturing accounts for the fact that the movement observed in Sandifer syndrome may be mistaken for seizures.
    • During the posture, the infant may become very quiet or, less commonly, become very fussy. Fussiness is most commonly observed as the posture abates.

Physical

In children with Sandifer syndrome without mental impairment, the examination findings are normal. Children with Sandifer syndrome with mental impairment often have evidence of spasticity and may be diagnosed with cerebral palsy.5

  • Sandifer syndrome in infants is most commonly associated with normal examination findings.
  • Sandifer syndrome in older children may be associated with mental impairment.

Causes

Dysfunction of the lower esophagus is thought to be the most common precipitating factor. In some children, a cause cannot be found.

  • GERD
  • Dysmotility of the esophagus: Esophageal dysmotility, characterized by low-amplitude waves, lack of normal propagation, and low lower esophageal sphincter (LES) pressure, is not the cause but most likely the consequence of esophagitis.



Gastroesophageal Reflux

Other Problems to be Considered

Seizures
Infantile spasms
Tonic seizures
Torticollis
Dystonia



Lab Studies

  • pH monitoring is useful in demonstrating gastroesophageal reflux and in clarifying any temporal association of reflux and posturing.

Imaging Studies

  • Barium swallow studies are used less frequently, although they may be useful in documenting anatomy and the possible association with hiatal hernia.
  • Cranial MRI is helpful in defining the nature of the neurologic deficits in children with mental impairment.

Other Tests

  • Video-EEG monitoring helps differentiate seizures from posturing related to reflux and can be combined with a pH probe study to demonstrate the nature of the spells.

Procedures

  • Endoscopy may confirm anatomy and allows biopsy samples to be obtained to confirm mucosal changes due to esophagitis.



Medical Care

Sandifer syndrome does not require treatment unless the spasms are related to GI causes. In the latter case, therapy should be directed towards the specific cause (see Gastroesophageal Reflux).

  • The primary aim of medical care is to identify Sandifer syndrome.
    • This can be accomplished most often by soliciting a careful history of the times of day the spasms occur and the precipitating causes.
    • If recognizing the complex is difficult, then video-EEG monitoring may be of value.
  • Often, parent education and explanation regarding the nature of the spasms are all that is required in treatment of this condition. If the patient does have pathologic gastroesophageal reflux or complications from gastroesophageal reflux such as esophagitis, then therapy for gastroesophageal reflux, or specifically for esophageal peptic disease, is indicated.
  • Muscle relaxants could be used in patients with Sandifer syndrome in whom a GI cause has been excluded and seizurelike postures are causing distress and discomfort for the patient or their family. However, muscle relaxants have not been demonstrated to relieve the seizurelike manifestations of Sandifer syndrome.

Consultations

  • Primary consultations should be with a gastroenterologist.
  • If any doubt surrounds the nature of the seizurelike activity or if the child has underlying neurologic impairment, a consultation with a pediatric neurologist could be beneficial.

Diet



Therapeutic response for the treatment of gastroesophageal reflux disease may take as long as 2 weeks. If treatment is successful, weight increases and vomiting episodes decrease.

Drug Category: Unknown Drug Category

These agents are used to augment cholinergic activity. Prokinetic pharmacotherapy is often used before acid suppression therapy in children without evidence of esophagitis because of the predominance of motility-related problems over increased acid (and regurgitation over pain) in the pathogenesis and presentation.

Drug NameMetoclopramide (Reglan)
DescriptionDopaminergic antagonist that works by increasing LES tone and gastric emptying. Stimulates muscular activity, leading to decrease in reflux.
Adult Dose10-15 mg PO qid
Pediatric Dose0.4-0.8 mg/kg/d PO/IV/IM divided qid; not to exceed to 5 mg/dose
ContraindicationsDocumented hypersensitivity; pheochromocytoma; GI hemorrhage, obstruction, or perforation; history of seizure disorders
InteractionsAnticholinergic agents may antagonize effects of metoclopramide; opiate analgesics may increase metoclopramide toxicity in CNS; metoclopramide may increase cyclosporine levels
PregnancyB - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
PrecautionsCaution in history of mental illness and Parkinson disease; adverse effects include restlessness and dystonia (can treat with diphenhydramine); narrow therapeutic index (avoid overdosing)

Drug Category: Antacids

These agents are used as diagnostic tool in providing symptomatic relief in infants. Associated benefits include symptomatic alleviation of constipation (aluminium antacids) or loose stools (magnesium antacids).

Drug NameAluminum hydroxide (ALternaGEL, Amphojel)
DescriptionIncreases gastric pH above 4 and inhibits proteolytic activity of pepsin, reducing acid indigestion. Antacids can initially be used in mild cases. No effect on frequency of reflux but decreases its acidity.
Adult Dose5-15 mL/dose PO qd-qid
Pediatric Dose2.5-5 mL/dose PO qd-qid
ContraindicationsDocumented hypersensitivity
InteractionsDecreases effects of tetracyclines, ranitidine, ketoconazole, benzodiazepines, penicillamine, phenothiazines, digoxin, indomethacin, and isoniazid; corticosteroids decrease effects of aluminum in hyperphosphatemia
PregnancyB - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
PrecautionsCaution in recent massive upper GI hemorrhage and in infants; renal failure may cause aluminum toxicity; can cause constipation

Drug NameMagnesium hydroxide (Phillips Milk of Magnesia)
DescriptionCauses osmotic retention of fluid, which distends colon and increases peristaltic activity. Forms magnesium chloride in vivo after reacting with stomach hydrochloric acid.
Adult Dose1 mL/kg/dose PO qid ac and hs
Pediatric Dose2.5-5 mL as needed; not to exceed 20 mL/d
ContraindicationsDocumented hypersensitivity; colostomy; ileostomy; renal failure; fecal impaction; appendicitis
InteractionsDecreases effects of tetracyclines, digoxin, indomethacin, and iron salts
PregnancyB - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
PrecautionsCaution in severe renal impairment and in infants; can cause diarrhea

Drug Category: H2 receptor antagonists

Like antacids, these agents do not reduce the frequency of reflux, but they decrease the amount of acid in the refluxate by inhibiting acid production. All are equipotent when used in equivalent doses. Work best in patients with nonerosive esophagitis. Because of proton pump inhibitor (PPI) superiority, H2 blockers are reserved for use in patients unable to tolerate PPIs.

Drug NameCimetidine (Tagamet)
DescriptionInhibits histamine at H2 receptors of gastric parietal cells, resulting in reduced gastric acid secretion, gastric volume, and hydrogen ion concentrations.
Adult Dose10-15 mg/kg/dose PO qid ac and hs or 800 mg PO bid or 400 mg PO qid
Pediatric DoseNeonates: 5-10 mg/kg/d PO/IV/IM divided q8-12h
Infants: 10–20 mg/kg/d PO/IV/IM divided q6-12h
Children: 20-40 mg/kg/d PO/IV/IM divided q6h; not to exceed 300 mg/dose
ContraindicationsDocumented hypersensitivity
InteractionsCan increase blood levels of theophylline, warfarin, tricyclic antidepressants, triamterene, phenytoin, quinidine, propranolol, metronidazole, procainamide, and lidocaine
PregnancyB - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
PrecautionsMay increase levels of many drugs; adjust dose or discontinue treatment if changes in renal function occur; adverse effects include headache and pancytopenia

Drug NameRanitidine (Zantac)
DescriptionInhibits histamine stimulation of the H2 receptor in gastric parietal cells, which reduces gastric acid secretion, gastric volume, and hydrogen ion concentrations.
Adult Dose3.5 mg/kg/dose PO bid/tid ac and hs or 75-150 mg PO bid
Pediatric DoseNeonates and term infants: 2 mg/kg/d PO divided q12h or 1.5 mg/kg/d IV divided q12h
Children: 4-5 mg/kg/d PO divided q8-12h; not to exceed 300 mg/d
ContraindicationsDocumented hypersensitivity
InteractionsMay decrease effects of ketoconazole and itraconazole; may alter serum levels of ferrous sulfate, diazepam, nondepolarizing muscle relaxants, and oxaprozin
PregnancyB - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
PrecautionsCaution in renal or liver impairment; if changes in renal function occur during therapy, consider adjusting dose or discontinuing treatment; adverse effects include headache and malaise

Drug NameFamotidine (Pepcid)
DescriptionCompetitively inhibits histamine at H2 receptor of gastric parietal cells, resulting in reduced gastric acid secretion, gastric volume, and hydrogen ion concentrations.
Adult Dose20 mg PO bid
Pediatric Dose>1 year: 1 mg/kg/d PO/IV divided q12h; not to exceed 80 mg/d
ContraindicationsDocumented hypersensitivity
InteractionsMay decrease effects of ketoconazole and itraconazole
PregnancyB - Fetal risk not confirmed in studies in humans but has been shown in some studies in animals
PrecautionsAdjust dose in renal insufficiency

Drug Category: Proton pump inhibitors

These agents are indicated in patients who need complete acid suppression (eg, infants with chronic respiratory disease or neurologic disabilities). Administer with the first meal of the day (children with nasogastric or gastrostomy tubes may have granules mixed with an acidic juice, then flush tubes to prevent blockage).

Drug NameOmeprazole (Prilosec)
DescriptionDecreases gastric acid secretion by inhibiting the parietal cell H+/K+-ATP pump. Used for the short-term treatment (4-8 wk) of GERD.
Adult Dose20-40 mg PO qd
Pediatric Dose0.7-3.3 mg/kg/d PO
<30 kilograms: 20 mg/d PO initial
>30 kilograms: 40 mg/d PO initial
ContraindicationsDocumented hypersensitivity
InteractionsMay decrease effects of itraconazole and ketoconazole; may increase toxicity of warfarin, digoxin, and phenytoin
PregnancyC - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
PrecautionsAdverse effects include headache, rash, diarrhea, hypergastrinemia, and polyps



Prognosis

  • Typically, Sandifer syndrome is not life threatening. Many patients with the condition eventually outgrow the spasms in later childhood.



Medical/Legal Pitfalls

  • The diagnosis of Sandifer syndrome should not be made without adequate study.
  • Patients may have infantile spasms that require relatively rapid treatment and management. An EEG often helps exclude infantile spasms. In infantile spasms, a hypsarrhythmia is observed on EEG.
