1/43. Successful treatment with methylprednisolone pulse therapy for a life-threatening pulmonary insufficiency in a patient with chronic granulomatous disease following pulmonary invasive aspergillosis and burkholderia cepacia infection. A 14-year-old boy with X-linked chronic granulomatous disease developed severe invasive pulmonary aspergillosis. He was treated with itraconazole and amphotericin b. However, he deteriorated with progressive pulmonary lesions. burkholderia cepacia was isolated from his bronchoalveolar lavage. Finally, he was given granulocyte transfusions. Following this procedure, his condition rapidly worsened leading to respiratory failure. His lung biopsy demonstrated organizing pneumonia at his right middle lobe. Then, a methylprednisolone pulse therapy was initiated together with the administration of appropriate antibiotics and adequate amounts of amphotericin b. Dramatically, his condition improved. Therefore, a methylprednisolone pulse therapy with appropriate antimicrobial drugs seems to be beneficial for severe pulmonary insufficiency in this type of patients. copyright copyright 1999 S.

| We present the histopathologic features of fatal burkholderia cepacia pneumonia in three adults (one man [age 44 years] and two women [aged 40 and 43 years]). In all patients, the pulmonary infiltrates initially were localized (right middle lobe, left upper lobe, and right middle lobe) but rapidly progressed. Two open-lung biopsies and one pneumonectomy specimen showed necrotizing granulomatous inflammation merging with areas of more conventional necrotizing bronchopneumonia In one patient, a mediastinal lymph node also showed stellate necrotizing granulomas. vasculitis was absent. B. cepacia was cultured from the open-lung biopsies and bronchial wash specimens in two patients and from postmortem cultures of lung, subcarinal lymph nodes, and blood in the third. The histopathology in these patients resembles that of melioidosis, which is caused by a related organism, burkholderia pseudomallei. B. cepacia needs to be considered in the differential diagnosis of necrotizing granulomatous inflammation. In addition, given the rarity with which B. cepacia is identified as a cause of pneumonia in the immunocompetent host, isolation of B. cepacia should trigger a workup for underlying immunodeficiency or lead to an investigation to exclude the possibility of a nosocomial infection.

3/43. Transient asceptic arthritis of knees in a patient with melioidosis. osteomyelitis and septic arthritis are known manifestations of melioidosis. Whether reactive arthritis can occur as a sequele to B. pseudomallei infection, is yet to be seen. As more and more cases of melioidosis will be reported in future, this aspect has to be kept in mind. ( info) |
| We describe a case of an adult patient with cystic fibrosis who developed chronic pulmonary infection and multiple episodes of soft tissue abscesses with burkholderia gladioli; this organism should be added to the list of potential pathogens for individuals with cystic fibrosis. ( info) |
5/43. Persistent bacteraemia caused by a single clone of burkholderia cepacia with unusual phenotype. We report a case of persistent bacteraemia caused by a single clone of burkholderia cepacia with unusual characteristics. Six isolates of B. cepacia were recovered from a patient with acute myeloid leukaemia and chemotherapy-induced neutropenia within a 3-week period. All six isolates were initially incompletely identified as B. cepacia with the API 20NE system. The further use of cellular fatty acid analysis and PCR-restriction fragment length polymorphism of the 16S rDNA confirmed the identification. These isolates also displayed an identical but unusual antibiotype. The identical cellular fatty acid profiles and genomic typing generated by random amplified polymorphic dna identified these isolates as derivatives of a single strain. ( info) |
| We describe an 11-year-old girl with cystic fibrosis (CF) who presented with respiratory failure and burkholderia cepacia bacteremia (cepacia syndrome). She survived her illness after aggressive treatment with parenteral antibiotics and corticosteroids. We speculate that treatment with corticosteroids may decrease the influx of proinflammatory cytokines and neutrophil-induced inflammation, with resulting improvement in the outcome of cepacia syndrome in CF patients.

7/43. Misidentification of a genomovar of burkholderia cepacia by recA restriction fragment length polymorphism. An 8 year old girl with cystic fibrosis presented with a pulmonary exacerbation from which burkholderia cepacia was cultured. Subsequent polymerase chain reaction restriction fragment length polymorphism analysis of the recA gene suggested the presence of B cepacia Genomovar V (Burkholderia vietnamiensis); however, on subsequent sequence typing, this isolate was confirmed as B cepacia Genomovar IIIb. This report outlines the potential difficulties in the correct characterisation of the various genomovars within the B cepacia complex of organisms, which has particularly important implications for patient segregation and infection control.

| PURPOSE: To report a case of burkholderia gladioli keratitis with consecutive endophthalmitis. methods: Case report and literature review. RESULTS: A 76-year-old man with a history of diabetes mellitus developed bacterial keratitis and consecutive endophthalmitis in the corneal graft of the left eye. Corneal, aqueous, and vitreous cultures yielded burkholderia gladioli. Emergent keratoplasty, pars plana vitrectomy, and injection of intravitreal antibiotics led to resolution of the infection and improved vision. Four months later, the patient developed recurrent Burkholderia keratitis and endophthalmitis, necessitating a total keratoplasty and repeat injection of intravitreal antibiotics. CONCLUSION: This is the first report, to our knowledge, of ocular burkholderia gladioli infection, an uncommon aerobic, gram-negative rod, recently subclassified from the genus pseudomonas based on dna-rRNA homology studies.

| urinary tract infection is a common complication after renal transplantation. The etiologies are diverse and the bacterial agents may sometimes be acquired during the hospital stay. We report a patient who developed burkholderia cepacia urinary tract infection after renal transplantation. The bacteria showed in vivo resistance to all of the available antibiotics. A graft nephrectomy was eventually required to clear the infection. The consequence of some fastidious infection may be catastrophic and early recognition and treatment is necessary to optimize the treatment. ( info) |
| PURPOSE: To report polymicrobial keratitis in a patient with herpetic stromal keratitis. The initial infecting organism, Burkholderia ambifaria, has not previously been reported to cause microbial keratitis. methods: Clinical evaluation and corneal culture were performed. RESULTS: A 59-year-old-man undergoing topical corticosteroid therapy for herpes simplex stromal keratitis developed corneal infection with B. ambifaria. The organism was reisolated 12 days after initiation of hourly therapy with topical levofloxacin 0.5%. At reculture staphylococcus aureus and enterococcus spp. were also isolated. The addition of topical amikacin and vancomycin led to resolution of the microbial keratitis. CONCLUSIONS: Burkholderia ambifaria infected a compromised cornea, exhibited an unusual sensitivity profile, and remained viable after 12 days of therapy with an antibiotic to which it was sensitive by in vitro tests.
