Prediction of morbidity in Hemophilus influenzae meningitis
Abstract:
A dramatic decrease in mortality from Hemophilus influenzae meningitis has occurred in recent years. Morbidity and long-term sequellae remain significant problems. A follow-up investigation of 73 cases of H. influenzae meningitis seen over a three-year period revealed: 2 deaths, 6 children with major sequellae (retardation, spastic quadriplegia, blindness, persistent seizure disorder), 10 with minor residua, and 55 with no detectable disability. Statistical analysis of clinical parameters demonstrated a significant risk of death or major morbidity in those patients who, at the time of admission, had seizures, coma, hypothermia, shock, age less than 12 months, hemoglobin less than 11 gm/100 ml, pretreatment symptoms for longer than three days, a spinal fluid white blood cell count less than 1,000/cu mm, or a spinal fluid glucose value less than 20 mg/100 ml. Using these parameters, those patients at highest risk of having lasting major morbidity with H. influenzae meningitis can be predicted, allowing more vigorous intensive care which may reduce the mortality and morbidity further.
Insights
Mortality from Hemophilus influenzae meningitis has decreased, but long-term disability remains a concern. Identifying high-risk patients using specific clinical indicators can improve intensive care and reduce Hemophilus influenzae meningitis sequelae.
Area of Science:
- Pediatrics
- Infectious Diseases
- Neurology
Background:
- Mortality from Hemophilus influenzae meningitis has significantly declined.
- Despite reduced deaths, morbidity and long-term sequelae persist as major challenges.
Purpose of the Study:
- To identify clinical parameters predictive of death or major morbidity in Hemophilus influenzae meningitis.
- To enable early identification of high-risk patients for improved intensive care.
Main Methods:
- A follow-up investigation of 73 cases of Hemophilus influenzae meningitis over three years.
- Statistical analysis of clinical parameters at admission, including seizures, coma, hypothermia, shock, age, hemoglobin levels, symptom duration, and cerebrospinal fluid values.
Main Results:
- Two deaths and significant long-term sequelae (major and minor) were observed in the 73 cases.
- Key predictors of death or major morbidity included seizures, coma, hypothermia, shock, young age (<12 months), low hemoglobin, prolonged symptoms (>3 days), low CSF white blood cell count (<1,000/cu mm), and low CSF glucose (<20 mg/100 ml).
Conclusions:
- Specific clinical indicators at admission can predict patients at highest risk for death or lasting major morbidity from Hemophilus influenzae meningitis.
- Early identification of these high-risk patients allows for more aggressive intensive care, potentially further reducing mortality and morbidity.
