During the last twenty years pleuropneumonia in pigs, caused by Haemophilus pleuropneumoniae, has spread globally. The increasing importance of the disease within swine production is apparently connected with increasing industrialization and subsequent heavy concentration of a large number of animals in the individual production unit. Haemophilus pleuropneumoniae seems to be specific for pigs. Several more or less pathogenic serotypes of the bacterium are known. Serotype 2 as occurring in Denmark is primary pathogen for pigs which have not previously been in contact with the infection. Immunity of varying strength and duration is left after recovery. Prolonged immunity in an animal is presumably dependent on latent infection or on repeated infections. Normally there is a large number of latently infected animals in attacked herds. Such animals, especially sows and boars, represent a potential infection reservoir which might be the basis of new clinical outbreaks under conditions of reduced herd immunity or of compromised general resistance of animal groups. Clinical disease is most frequently seen in young pigs and fatteners, as piglets are generally protected by maternal antibodies. Acute pleuropneumonia is characterized by high temperature, lost appetite, light cough and often vomiting. Morbidity is high, especially by new-infection where there may also be considerable mortality if adequate antibacterial therapy is neglected, however, normally the disease implies low mortality. The pathological lesions are localized to the respiratory organs. The lungs are the seat of fibrinous necrotising pneumonia (red, grey hepatization), more or less extensive, most frequently of the diaphragmatic part of the lung. Furthermore fibrinous, later on fibrous pleuritis and pericarditis may be seen. The fibrous pleuritis may be of decisive diagnostical value when established with high frequency in baconers. The disease causes losses as a consequence of increased use of medicine and reduced daily weight gain in fatteners. Optimum environment and feeding conditions will reduce such losses considerably. The use of commercially available vaccines makes it possible to fortify specific resistance against the disease in exposed groups of animals. In small herds with few infected animals the infection may be eliminated by discarding seropositive animals, combined with strategic medication. Elimination of the infectious agent in large herds can only take place by replacing all animals by an SPF-herd.

Acute purulent pericarditis caused by Haemophilus influenzae is an unusual condition, especially in childhood. In most cases, respiratory symptoms are the presenting features, and children aged less than 4 years are most often affected. A high index of suspicion and aggressive microbiological and cardiological evaluation are often warranted to make an early diagnosis. We herein report two cases of pericarditis caused by H. influenzae in children aged less than two years. Pericardiocentesis was performed in each case. Early recognition, rapid diagnosis and aggressive medical and surgical therapy are paramount in the successful treatment of this condition.

Sixteen children, aged 7 months to 12 years, with acute pericarditis, admitted between 1985 and 1993 to a tertiary referral centre were analyzed retrospectively for their presentation, etiology, work-up, management and prognosis. It was found that most of the presenting signs were not specific and were often related to associated diseases such as respiratory tract infections. In 50% of the cases a cause was not found, the others had viral infections (12.5%), tuberculosis (12.5%), Haemophilus influenzae infection (6.25%), Toxocara canis infection (6.25%) and collagen diseases (12.5%). In eight cases non-steroidal anti-inflammatory drugs associated with steroids were given, 7 patients received non-steroidal anti-inflammatory drugs and 1 steroids. The mean follow-up time was 3 years (1 to 5). Six patients had one or more relapses. Five of the 6 patients with relapses were in the group which received steroids. The two patients with tuberculosis underwent pericardiectomy. One child died due to complex heart disease and the remaining 15 were cured. It was concluded that in pericarditis an extensive work-up may not reveal the major etiologies and that long term prognosis is good.

Acute purulent pericarditis is a rare entity in the neonatal age group. The most common isolated organisms are Staphylococcus aureus, Haemophilus influenzae, and Streptococcus pneumoniae. Other organisms, like Pseudomonas aeruginosa, have been seldom implicated with only one case of Pseudomonas pericarditis reported in the neonatal period. The prognosis is often considered very poor in this age group. This article describes Pseudomonas pericarditis in a 1-week-old immunocompetent female newborn who was successfully managed with combined medical and surgical therapy.

A surgical case of acute purulent pericarditis in 1-year 2-month old boy who developed pericardial tamponade rapidly is reported. A subxiphoid pericardiectomy through a median incision was performed. Haemophilus influenzae was isolated from the effusion. He recovered successfully with an administration of antibiotics after the drainage procedures and did not develop constructive pericarditis. Our experience suggested that early subxiphoid pericardial drainage was effective in treatment of acute purulent pericarditis.

Purulent pericarditis in children is a life-threatening disease that requires early diagnosis and immediate intervention. This cardiac emergency is rarely seen in the western world. However, cases of purulent pericarditis are still being reported in developing countries. We describe our experience with five cases of purulent pericarditis in children seen between 1998 and 2002. Haemophilus influenzae bacteria were isolated in all except one case. With active management, all five children survived.

Two adult patients with pericarditis caused by beta-lactamase producing Haemophilus influenzae are reported and their management reviewed. Both had pharyngitis, epiglottitis, pneumonia, empyema, or septicemia and were cured with antimicrobics and pericardial drainage (one by catheter and one by surgery). Eleven previously reported cases of pericarditis caused by Haemophilus influenzae are also reviewed. In reviewing this rare cause of bacteria pericarditis, it is important to recognize the antibiotic resistance profile, the incidence of pericardial tamponade, and the use of surgical drainage. Antibiotic selection for this organism is also discussed, as well as the importance of biotyping.

Although cardiac tamponade is an important and emergent complication of systemic lupus erythematosus (SLE), purulent pericarditis is rare despite the high frequency of pericardial effusion in SLE. We describe the first SLE case of Haemophilus influenzae type-f pericarditis with cardiac tamponade with SLE as the initial presentation. The pathophysiology and therapy are discussed.

Bacterial pericarditis occurs by direct infection during trauma, thoracic surgery, or catheter drainage, by spread from an intrathoracic, myocardial, or subdiaphragmatic focus, and by hematogenous dissemination. The frequent causes are Staphylococcus and Streptococcus (rheumatic pancarditis), Haemophilus, and M. tuberculosis. In AIDS pericarditis, the incidence of bacterial infection is much higher than in the general population, with a high proportion of Mycobacterium avium-intracellulare infection. Purulent pericarditis is the most serious manifestation of bacterial pericarditis, characterized by gross pus in the pericardium or microscopically purulent effusion. It is an acute, fulminant illness with fever in virtually all patients. Chest pain is uncommon. Purulent pericarditis is always fatal if untreated. The mortality rate in treated patients is 40%, and death is mostly due to cardiac tamponade, systemic toxicity, cardiac decompensation, and constriction. Tuberculous infection may present as acute pericarditis, cardiac tamponade, silent (often large) relapsing pericardial effusion, effusive-constrictive pericarditis, toxic symptoms with persistent fever, and acute, subacute, or chronic constriction. The mortality in untreated patients approaches 85%. Urgent pericardial drainage, combined with intravenous antibacterial therapy (e.g. vancomycin 1g twice daily, ceftriaxone 1-2g twice daily, and ciprofloxacin 400 mg/day) is mandatory in purulent pericarditis. Irrigation with urokinase or streptokinase, using large catheters, may liquify the purulent exudate, but open surgical drainage is preferable. The initial treatment of tuberculous pericarditis should include isoniazid 300 mg/day, rifampin 600 mg/day, pyrazinamide 15-30 mg/kg/day, and ethambutol 15-25 mg/kg/day. Prednisone 1-2 mg/kg/day is given for 5-7 days and progressively reduced to discontinuation in 6-8 weeks. Drug sensitivity testing is essential. Pericardiectomy is reserved for recurrent effusions or continued elevation of central venous pressure after 4-6 weeks of antituberculous and corticosteroid therapy.

Haemophilus aphrophilus, an oral fastidious Gram-negative commensal with low pathogenicity, is a member of the HACEK group (H. aphrophilus, H. paraphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella spp.), and a rare cause of human infections. We reviewed the characteristics of 8 cases of H. aphrophilus infections diagnosed in our hospital from 1990-2003, and an additional 20 cases identified from the MEDLINE database, from 1990 to 2003. Their mean age was 47.4 years (range, 7-73 years), and 21 cases (75%) were male. The major manifestation was bone and joint infections (9 cases, 32%), including osteomyelitis, discitis, epidural abscess, spondylodiscitis, septic arthritis and prevertebral infection. Seven cases (25%) presented with infective endocarditis, involving native valves, and one underwent valvular replacement. Of note, 3 cases (10%) had ophthalmic infections (endophthalmitis in 2 cases and canaliculitis in 1), and 2 of them had previous ophthalmic procedures. Other manifestations included bacteremia, meningitis, brain abscess, cervical lymphadenitis, facial cellulitis, empyema, and purulent pericarditis and tamponade. All patients except 1 survived. Recent dental procedure was recalled by 11 cases (39%), and may be a predisposing factor for invasive H. aphrophilus infection. Appropriate antimicrobial therapy, such as a beta-lactam/beta-lactamase inhibitor, ceftriaxone or cefotaxime or a fluoroquinolone, can lead to a favorable clinical outcome.
