A 58-year-old man described a short history of dyspnea and a preceding flu like illness with roentgenographic features of an interstitial lung disease. An open lung biopsy specimen from him showed bronchiolitis obliterans with organizing pneumonia (BOOP). Adenovirus was isolated from a throat swab. There was both clinical and radiographic improvement with supportive care. We herein report a first case of BOOP associated with adenovirus in Korea.

Adenovirus pneumonia, while common in infancy and childhood, is rarely documented but may be fatal in the neonatal period. In regard to the serious outcome and no responsiveness to common anti-viral agents, adenovirus infection should be considered in the differential diagnosis of pneumonia in neonates. We report three cases of fatal neonatal adenovirus pneumonia, all of which were diagnosed by postmortem examination. Two patients were born by cesarean section at 35 or 36 weeks of gestation, and the other was a 5100 gm postmature baby born by vaginal delivery at 43 weeks of gestation. Respiratory insufficiency was detected just after birth or in the immediate postnatal period, and was associated with lethargy and chest X-ray findings of pneumonic infiltration. The postmortem findings of these patients were remarkably consistent and characterized by predominant lung involvement. The lungs showed diffuse massive consolidation with scattered patchy hemorrhage, and histologically revealed multifocal necrotizing alveolitis and/or bronchiolitis, often with hemorrhage. Alveolar lining cells and desquamated cells contained numerous smudge ells and many cells with characteristic inclusion bodies. Electron microscopy revealed that these inclusion bodies consisted of arrays of icosahedral particles of adenovirus. It is unusual that one of the patients, who was born by cesarean section without any evidence of prenatal infection, developed adenoviral pneumonia; this indicates that infection may occur in the immediate postnatal period as well as during passage of the birth canal.

Outbreaks of acute respiratory disease caused by adenovirus are rarely documented in civilian populations, and adenovirus 35 is an uncommon serotype best recognized as a cause of serious disease in immunocompromised patients. An outbreak of adenovirus 35 pneumonia among residents and staff of a chronic care psychiatric facility was investigated. Fourteen (26%) of 53 residents and 4 (2%) of approximately 200 staff had radiographically confirmed pneumonia. Thirteen (93%) of 14 residents with pneumonia were hospitalized, 5 (36%) required mechanical ventilation, and 1 (7%) died. One staff member was hospitalized. Adenovirus infection was diagnosed in 17 (94%) persons with pneumonia by culture or serology and was confirmed as adenovirus 35 infection in 8 persons. Residents with pneumonia had resided at the facility longer than other residents. Chronic illness was not a risk factor for severe disease. Crowding and poor hygienic behaviors probably facilitated transmission among residents.

Adenovirus infection occurs in 10% of pediatric orthotopic liver transplant recipients; however, no cases have been described in adult liver transplant recipients. A retrospective review of 191 adults who underwent liver transplantation from January 1988 through October 1995 was done to describe the incidence and clinical significance of adenovirus infection in this population. There were 11 (5.8%) patients with 16 cultures positive for adenovirus. Sites of isolation were urine (9), blood (2), liver biopsy (2), colonic biopsy (1), lung biopsy (1), and stool (1). Adenovirus infection was classified as either disease or asymptomatic infection. There were 7 cases of adenovirus disease (2 definite, 1 probable, and 4 possible). Disease was disseminated in 3 patients: All had pneumonia and 2 died. Of the 3 patients with pneumonia, 2 had evidence of multiorgan involvement. Adenovirus disease occurs in adult orthotopic liver transplant recipients and may be associated with significant morbidity and occasional mortality.

Eighteen cases of pneumonia developed during an outbreak of adenovirus infection in a chronic psychiatric care facility. The six patients most severely affected were admitted to the intensive care unit (ICU) at our institution. Four of these patients developed septic shock. We report the presentation, disease progression, and response to treatment of these patients. Clinical features consisted of high fever, nonproductive cough, and dense lower lobe infiltrates. Laboratory abnormalities included transient fall in white blood cell and platelet counts, and elevations of transaminases, lactate dehydrogenase (LDH), and creatinine phosphokinase (CPK). Five patients were intubated for hypoxemia and four developed the acute respiratory distress syndrome (ARDS) and septic shock (mean cardiac output, 14.1 +/- 1.3 L/min; cardiac index, 6.4 +/- 0.4 L/min/min2; systemic vascular resistance, 326 +/- 107 dyne cm/s2). All patients recovered and were discharged back to the chronic care facility except for one patient with chronic renal failure who died 2 mo after admission. Adenovirus (serotype 35) was isolated from the respiratory secretions of five patients and antibody titers increased 6-fold in the other. These patients constitute the largest series of patients with ARDS and septic shock caused by adenovirus pneumonia and the first outbreak of multiple cases of adenovirus pneumonia in immunocompetent civilian adults occurring from a single source.

Adenovirus (ADV) is increasingly recognized as a cause of morbidity and mortality in transplant recipients, but ADV pneumonitis has rarely been reported after lung transplantation. The few reported instances of ADV pneumonitis occurred mostly in children immediately after lung transplantation suggesting "primary" infection. We report a fatal case of ADV pneumonitis occurring in an adult, 4 years after unilateral lung transplantation, in whom the premortem diagnosis was not determined. Autopsy revealed severe necrotizing bronchitis, bronchiolitis, and interstitial pneumonitis. Characteristic smudgy intranuclear inclusions, immunohistochemistry for viral protein, in situ hybridization for viral genome, and postmortem lung cultures established ADV as the etiologic agent. ADV can cause fatal, occult respiratory infection in adult lung transplant recipients, remote from transplant surgery.

Adenovirus infections occur commonly in infants and children but are rarely fatal. Although immunosuppression has been associated recently with fatal outcome of adenovirus infections, reports of major morbidity or mortality caused by adenovirus infection in HIV positive patients are infrequent. This is the first report on fatal adenovirus infections in presumably HIV-positive infants in Thailand. Three infants, aged 4, 8 and 5 months, were hospitalized with diagnoses of pneumonia and ARDS, pneumonia with hepatomegaly and ARDS, and pediatric AIDS with pneumonia, respectively. All the infants died within a few weeks after hospitalization. Serologic tests revealed positive anti-HIV in all three infants. Unfortunately, no additional investigation for definite diagnosis of HIV infection was employed. Pathological findings from autopsy and post mortem needle biopsies revealed adenovirus pneumonia in the first two infants, and massive adenovirus infection of the liver in the third infant. Diagnoses were based on characteristic light microscopic pathological findings, and demonstration of viral particles arranged in crystalline arrays in the nucleus of the infected cells by electron microscopy.

We report a case of severe Adenovirus type 7 pleuropneumonia in an immunocompetent adult. The treatment required a mechanical ventilation with tracheostomy. The sequelae was a restrictive respiratory insufficiency. Adenovirus is a common cause of pneumonia in children, in military recruits or in immunocompromised adults. However, it is an infrequent cause of such a severe complication in a healthy adult.

Community viral bronchopneumonias are frequent, mainly in children, and can be associated to all respiratory viruses: influenza- and parainfluenzavirus, respiratory syncytial virus, adenovirus, rhinovirus. The diagnostic method which proves viral infection of the respiratory tissues is selected as the direct detection by an immunofluorescence assay of viral infected cells in respiratory samples. In them, viral isolation or nucleic acid detection by PCR provide an amplification of the viruses. By using PCR-hybridation techniques viral detection is overall increased of 1.5 times for respiratory syncytial virus, 1.9 for parainfluenzavirus 3, 4 for rhinovirus and 10 times for adenovirus. This increased sensitivity raises questions about the meaning of the detection of viral sequences in nasal aspirates, with or without clinical signs. Cytomegalovirus (CMV) is a major agent of pneumonia in immunocompromised patients. All virological markers of CMV infection have to be sought (antigenemia, viremia...), but specific inclusions in pulmonary cells are the single diagnosis criteria. As pulmonary biopsies are rarely available and CMV inclusions rarely found in BAL, it has been reported useful to look for high viral loads or late m-RMA transcripts in these samples. Adenovirus pneumonia are unfrequent in these patients and mostly associated to rare or atypical strains. Such PCR-hybridization systems deserves also to be used in these cases.

The results of a five-year study of paired sera from 410 hospitalised patients-mainly children-with respiratory illness are reported. Samples were divided into groups based on clinical diagnosis. The data of each group were analysed in relation to patient age (under or over 1 year of age). The percentage of positive serological diagnoses ranged from 29.4% in the respiratory viral illness group to 46.2% in the bronchiolitis group. Each group showed a prevalent serological diagnosis. Respiratory viral illness patients over 1 year were diagnosed mainly with Influenza virus infection (73.8% positive diagnosis), pharyngotonsillitis patients with Adenovirus infection (72.2%), laryngitis patients with Parainfluenza virus infection (100%), pneumonia patients with Mycoplasma pneumoniae infection (56.7%), and bronchiolitis patients with Respiratory Syncytial virus infection (100%). The serological diagnosis patterns of each group or subgroup were statistically significant with respect to the other groups (chi 2 or Fisher exact tests). Unlike previous reports, none of the patients under 1 year in our study was diagnosed with Influenza virus infection or Parainfluenza virus type 3. Conversely, Respiratory Syncytial virus infection data were in line with previous reports, being the most frequently diagnosed infection in the bronchiolitis group and in the subgroups of patients under 1 year of age. The present report provides new information on patterns of respiratory infections.
