ABSTRACT
Bacterial pericarditis is a rare disease in the era of antibiotics. Purulent pericarditis is most often caused by Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae. The number of H. parainfluenzae infections has been increasing; in rare cases, it has caused endocarditis. We report a case of purulent pericarditis caused by H. parainfluenzae in a 62-year-old woman who reported a recent upper respiratory tract infection. The patient presented with signs and symptoms of pericardial tamponade. Urgent pericardiocentesis restored her hemodynamic stability. However, within 24 hours, fluid reaccumulation led to recurrent pericardial tamponade and necessitated the creation of a pericardial window. Cultures of the first pericardial fluid grew H. parainfluenzae. Levofloxacin therapy was started, and the patient recovered. Haemophilus parainfluenzae should be considered in a patient who has signs and symptoms of purulent pericarditis. Prompt diagnosis, treatment, and antibiotic therapy are necessary for the patient's survival. To our knowledge, this is the first report of purulent pericarditis caused by H. parainfluenzae.

Haemophilus influenzae type b [Hib] can now be prevented by vaccination. We present the clinical and laboratory characteristics of acute invasive H. influenzae diseases in children admitted over a 4-year period to a tertiary paediatric ward of the Al-Ain medical district hospital, before vaccination became available in the United Arab Emirates. In all, 38 children had bacteriologically proven H. influenzae invasive diseases and all the isolates were serotype b. Meningitis was diagnosed in 60.5% of the children and 66% of the studied children were under 12 months. There were no deaths but substantial morbidity occurred in 12 children
