A case of post-transplantation pneumonia due to Candida krusei is reported. A 42-year-old man was admitted 28 days after heart transplantation with cough, pleuritic pain and fever. A chest computed tomograph showed multiple alveolar infiltrates bilaterally. He received broad-spectrum antibiotics, fluconazole for oral candidiasis, and cotrimoxazole for possible Pneumocystis carinii. A short-lived period of improvement was followed by respiratory failure. Cultures of bronchial washings grew C. krusei and C. albicans. The infection was documented by histology and culture obtained by transthoracic aspiration. Treatment with amphotericin B was initiated, but the patient died. Histology and culture of a pulmonary specimen, obtained immediately post mortem, further documented the infection with C. krusei.

Conflicting data exist regarding the relationship between Chlamydophila pneunoniae (C. pneumoniae) and hypertension. In this study, both C. pneumoniae IgG and IgA titres and Epstein-Barr virus antibody levels were measured in 146 sustained hypertensives defined by 24 h ambulatory blood pressure monitoring (ABPM) and 54 normotensives. C. pneumoniae antibodies were measured by microimmunofluorescence test. IgGX80 and IgAX40 were defined as elevated antibody titres. Epstein-Barr antibodies were measured in order to investigate whether a possible association exists between hypertension and other, similarly widespread in the general population, intracellular microorganisms. All participants underwent casual blood pressure (BP) readings and 24 h ABPM. Subjects having mean 24 h systolic/diastolic ambulatory BP4125/80 mmHg, with or without antihypertensive medication were defined as hypertensives. Controls were free of any history or clinical evidence of hypertension, cardiovascular or pulmonary disease. Of the total participants, 77 hypertensives (52.7%) and 10 normotensives (18.5%) had IgA titres X40 (crosstabs Po0.000), whereas 76 hypertensives (52.1%) and 15 normotensives (27.8%) had IgG titres X80, (crosstabs Po0.002). No difference was found in Epstein-Barr antibodies, between hypertensives and normotensives. In conclusion, C. pneumoniae, but not Epstein-Barr, antibody levels were found significantly higher in sustained hypertensives, suggesting high frequency of chronic C. pneumoniae, infections in this specific group of patients.
