Prediction of morbidity in Hemophilus influenzae meningitis.

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.
