Anemia with Haemophilus influenzae meningitis. 1980

K M Kaplan, and F A Oski

The hematologic values in patients with Haemophilus influenzae meningitis were contrasted with those of patients with other types of bacterial meningitis and aseptic meningitis in an attempt to determine whether anemia is either specific for or more common in patients with H influenzae meningitis. Patients with H influenzae meningitis had significantly lower admission hemoglobin values because they were significantly younger than the other two groups. The H influenzae meningitis patients with the lowest hemoglobin values on admission had been sicker for longer periods prior to diagnosis and had higher initial white cell counts. Patients with H influenzae meningitis, aged 3 to 24 months, developed lower hemoglobin values during hospitalization than did patients with other forms of meningitis. Anemia occurs with all forms of bacterial meningitis but is uncommon in aseptic meningitis. The anemia observed in patients with H influenzae meningitis, particularly those less than 2 years of age, is generally more severe than that observed in other forms of bacterial meningitis.

D008581	Meningitis	Inflammation of the coverings of the brain and/or spinal cord, which consist of the PIA MATER; ARACHNOID; and DURA MATER. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (HEMORRHAGES, SUBARACHNOID), chemical irritation (chemical MENINGITIS), granulomatous conditions, neoplastic conditions (CARCINOMATOUS MENINGITIS), and other inflammatory conditions may produce this syndrome. (From Joynt, Clinical Neurology, 1994, Ch24, p6)	Pachymeningitis,Meningitides,Pachymeningitides
D008582	Meningitis, Aseptic	A syndrome characterized by headache, neck stiffness, low grade fever, and CSF lymphocytic pleocytosis in the absence of an acute bacterial pathogen. Viral meningitis is the most frequent cause although MYCOPLASMA INFECTIONS; RICKETTSIA INFECTIONS; diagnostic or therapeutic procedures; NEOPLASTIC PROCESSES; septic perimeningeal foci; and other conditions may result in this syndrome. (From Adams et al., Principles of Neurology, 6th ed, p745)	Aseptic Meningitis
D008583	Meningitis, Haemophilus	Infections of the nervous system caused by bacteria of the genus HAEMOPHILUS, and marked by prominent inflammation of the MENINGES. HAEMOPHILUS INFLUENZAE TYPE B is the most common causative organism. The condition primarily affects children under 6 years of age but may occur in adults.

D004909	Erythrocyte Indices	ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT. The indices include the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the mean corpuscular hemoglobin concentration (MCHC).
