Insights
Children with acute otitis media (AOM) complicated by venous sinus thrombosis (VST) may have a prothrombotic tendency. This suggests a potential link between clotting disorders and VST in pediatric patients.
Area of Science:
- Pediatric Otolaryngology
- Neurology
- Hematology
Background:
- Venous sinus thrombosis (VST) is a significant intracranial complication of acute otitis media (AOM).
- Prothrombotic disorders, both inherited and acquired, are suspected risk factors for VST.
- Understanding these risk factors is crucial for effective prevention and treatment.
Purpose of the Study:
- To investigate the presence of a prothrombotic tendency in children diagnosed with AOM complicated by VST.
- To explore potential therapeutic and preventive strategies based on identified risk factors.
- To add to the body of evidence regarding VST etiology in pediatric populations.
Main Methods:
- Retrospective review of patient records from a tertiary referral center (1999-2002).
- Inclusion criteria: children hospitalized for AOM with acute mastoiditis and VST.
- Laboratory evaluation for hypercoagulability was performed on all included children.
Main Results:
- Five out of seven pediatric patients exhibited prothrombotic disorders.
- Identified disorders included elevated lipoprotein apolipoprotein (Lp[a]), antiphospholipid syndrome markers, and Factor V Leiden mutation.
- Patients presented with varying numbers of prothrombotic abnormalities, ranging from one to three.
Conclusions:
- A prothrombotic tendency appears to be present in children experiencing AOM complicated by mastoiditis and VST.
- Further research is warranted to fully elucidate the extent and implications of this tendency.
- Findings suggest a potential role for thrombophilia screening in this patient group.
Objective:
Venous sinus thrombosis (VST) is the second most common intracranial complication of acute otitis media (AOM). There is some evidence that hereditary and acquired prothrombotic disorders are risk factors for VST. The aim of the present study was to evaluate whether children with AOM complicated VST have a prothrombotic tendency, which might have important therapeutic and preventive implications.
Study Design:
Retrospective.
Methods:
The files of children hospitalized at Schneider Children's Medical Center of Israel, a tertiary referral center, from 1999 to 2002, because of AOM complicated by acute mastoiditis and VST were reviewed. All children underwent laboratory work-up for hypercoagulability.
Results:
Seven children met the study criteria. Of these, five had prothrombotic disorders, namely elevated levels of lipoprotein apolipoprotein (Lp[a]) (n = 4), antibodies to beta 2-glycoprotein and to cardiolipin (markers of antiphospholipid syndrome) (n = 4), and heterozygosity for factor V Leiden mutation (n = 1). One child had three abnormalities, two children had two abnormalities, and two children had one abnormality.
Conclusions:
A prothrombotic tendency may exist in children with AOM complicated by mastoiditis and VST. Further studies are needed to evaluate its extent.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
