Summary
Subacute sclerosing panencephalitis (SSPE) incidence in Istanbul is 2 per million. Measles vaccination is highly protective, while younger age and crowded living increase SSPE risk.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Background:
- Subacute sclerosing panencephalitis (SSPE) is a rare, fatal neurological complication of measles infection.
- The incidence and epidemiological factors of SSPE in Turkey, specifically Istanbul, were previously unknown.
Purpose of the Study:
- To determine the incidence rate of SSPE in Istanbul.
- To identify epidemiological characteristics and risk factors associated with SSPE development in Istanbul.
Main Methods:
- An active surveillance study was conducted in Istanbul from July 1, 2002, to July 1, 2004.
- Logistic regression analysis was used to identify risk factors for SSPE.
Main Results:
- The incidence of SSPE in Istanbul was found to be 2 per million.
- Risk factors included younger age, crowded households, low maternal education, and low income.
- Not being vaccinated against measles and prior measles infection were significant risk factors.
Conclusions:
- Measles vaccination is highly protective against SSPE.
- SSPE is strongly associated with measles infection, highlighting the importance of vaccination programs.
