Purpose Of The Review:
Subacute sclerosing panencephalitis (SSPE) is a rare, slowly progressive, and frequently fatal neurodegenerative disorder caused by measles virus. The risk of SSPE remains significant globally, with fluctuating incidence noted in in tandem with measles vaccine uptake. This review aims to explore the current global status of SSPE, its treatment, and preventive measures.
Recent Findings:
An increase in measles cases have been reported in various parts of the world for different reasons related to the regional context of the outbreak. With reduction in measles vaccine doses since the onset of the COVID-19 pandemic, the future risk of SSPE can only accelerate. In recent years, subsequent cases of SSPE have been reported in the period following documented measles outbreaks in different settings. Concomitantly, there have been efforts to evaluate the efficacy of immunomodulatory, antiviral, and anti-seizure therapies that could ameliorate the devastating effects of this disease. This review elucidates on these approaches and their limitations, reasons for poor vaccine coverage in low- and middle-income countries, as well as the possible solutions to the prevention of measles and eventual avoidance of SSPE.
Summary:
Prevention of measles virus infection with the resultant sequelae would be the most effective strategy for the management of SSPE. This approach would be particularly important in low resource setting that currently bears the double burden of widespread communicable diseases and malnutrition.
Insights
Subacute sclerosing panencephalitis (SSPE) is a fatal measles virus complication. Declining measles vaccination rates increase SSPE risk, necessitating global prevention strategies.
Area of Science:
- Neurology
- Infectious Diseases
- Public Health
Background:
- Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, and fatal neurodegenerative disease caused by the measles virus.
- Global SSPE incidence fluctuates with measles vaccine uptake, highlighting a persistent risk.
- Recent increases in measles cases and reduced vaccination rates, particularly post-COVID-19, are predicted to accelerate SSPE risk.
Purpose of the Study:
- To review the current global status of SSPE.
- To explore existing and emerging treatment strategies for SSPE.
- To identify effective preventive measures against measles and subsequent SSPE.
Main Methods:
- Literature review of global SSPE epidemiology.
- Analysis of current treatment modalities including immunomodulatory, antiviral, and anti-seizure therapies.
- Examination of factors influencing measles vaccine coverage and SSPE prevention strategies.
Main Results:
- Measles outbreaks and decreased vaccination rates are linked to increased SSPE incidence.
- Current therapeutic approaches for SSPE have limitations.
- Poor vaccine coverage in low- and middle-income countries exacerbates the risk.
Conclusions:
- Preventing measles virus infection is the most effective strategy for SSPE management.
- Addressing barriers to vaccination in resource-limited settings is crucial.
- Global efforts to improve measles vaccination are essential to prevent SSPE and its devastating consequences.
