Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study reports seven cases of subacute sclerosing panencephalitis (SSPE), a fatal brain disease caused by persistent measles virus infection, identified in Romanian children between 2021 and 2025. Six children contracted measles before age two, and all developed progressive neurological decline despite treatment. The reappearance of SSPE after a 10-year gap highlights the dangers of declining measles vaccination coverage.
Key points
- Seven children diagnosed with SSPE over five years, mean age 8.4 years, following measles infection in infancy or early childhood
- Mean latency period from measles infection to SSPE diagnosis was 7.1 years (range 4-9 years)
- All patients presented with clinical stage II symptoms and EEG abnormalities at admission
- Despite treatment with isoprinosine and anticonvulsants, all patients experienced progressive cognitive and neurological deterioration
- SSPE had not been reported in Romania for 10 years before this cluster, indicating a resurgence linked to reduced vaccination coverage
Limitations
This is a retrospective case series from a single hospital with no comparison group or follow-up outcomes data, so it cannot establish causation or estimate population-level incidence. The document does not provide information on vaccination status of the broader child population or reasons for declining coverage.
Abstract
BACKGROUND: Subacute sclerosing panencephalitis (SSPE) is a chronic, progressive disease of the central nervous system (CNS) caused by persistent infection at this level with the wild measles virus. Its incidence is negatively correlated with measles vaccination coverage. The pathogenesis isn't fully understood, but infection before the age of 2 is an important risk factor. METHODS: This is a retrospective observational study conducted at the Louis Turcanu Emergency Children's Hospital in Timisoara, Romania, based on the analysis of the medical records of patients diagnosed with SSPE between January 2021 and December 2025. We analyzed demographic and epidemiological factors, clinical and paraclinical findings, management, and outcomes. RESULTS: Seven children were diagnosed during the study period, with a mean age of 8.4 years (range 7-11 years). Six of them had contracted measles during their first year of life, and one at the age of four. The mean latency period was 7.1 years (range 4-9 years). On admission, all patients presented symptoms consistent with clinical stage II, with periodic slow wave discharges on electroencephalogram (EEG). The initial brain Magnetic Resonance Imaging (MRI) was normal in two cases, while revealing varied abnormalities in all others. Despite complex treatment with isoprinosine and anticonvulsants, progressive cognitive and neurological deterioration continued in all patients. CONCLUSIONS: SSPE is a rare but serious, debilitating disease despite its complex, multidisciplinary care. Following a 10-year SSPE-free period, the reappearance of these pediatric cases constitutes a public health alert, unequivocally demonstrating the importance of measles vaccination.
