[Occupational exposure induced human transmissible highly pathogenic H5N1 avian influenza in one patient].
OBJECTIVE
To describe the clinical manifestations and lung imaging characteristics of the human transmissible highly pathogenic H5N1 avian influenza.


METHODS
The clinical manifestations and lung imaging characteristics of human transmissible highly pathogenic H5N1 avian influenza in one patient were reviewed and analyzed.


RESULTS
The patient had the clear history of occupational exposure. The fever and symptoms of influenza were prominent at onset and associated with the symptoms of the digestive tract. The laboratory findings comprised the significant decrease of the white blood cell count and the lymphocyte number and the impairment of the liver function and the myocardial enzymes. The disease progressed rapidly and multiple organs including lung, heart, liver and kidneys were involved. It was ineffective to administer anti-fungal, anti-virus and anti-inflammation medicines. It was in vain to use mechanical ventilation and pneumothorax intubation and closed drainage as well as the support therapy. In the X-ray film, the lesions progressed quickly and changed diversely with absorption and development at the same time. The nasal and throat swabs and the gargle specimen were detected with RT-PCR and real time PCR by Chinese Center for Disease Control and Prevention. The results showed that both the specific HA and NA genes of the avian influenza virus H5N1 subtype were positive and in the same time a strain of avian influenza virus A/jiangxi/1/2005H5N1) was separated and obtained from the nasal and throat swabs. The autopsy showed that diffuse injury of alveolus in lungs, DIC and multiple organ injury.


CONCLUSIONS
The human transmissible highly pathogenic H5N1 avian influenza is a lethal disease. The disease progresses rapidly with the absorption and development at the same time in the lungs and unfortunately there are no effective therapeutic measures. The prevention of the contagious disease for the occupationally exposed population should be emphasized.
