    Abstract:
    OBJECTIVE: To investigate the clinical features of severe acute respiratory syndrome (SARS). METHODS: Forty-one medical care workers (aged 23 - 55 years, with a average of 32 years; men/women = 8/32) who were admitted to our hospital and diagnosed with SARS during March and April, 2003 were retrospectively analyzed. RESULTS: Thirteen of all the patients were physicians and the rest were nurses. The disease was mainly transmitted through air droplet in a short distance, and overwork induced tiredness was involved in disease stimulation. Seventy-three percent of the patients presented fever as their first symptom. Ten patients complained inertia and myalgia. One patient showed no clinical symptoms, and bilateral infiltrates was found in his chest X-ray. Among the 41 cases, 6 (15%) were diagnosed as severe type. At the first week, the counts of white blood cells (WBCs), lymphocyte and platelets were (4.4 +/- 1.5) x 10(9)/L, 0.22 +/- 0.12 and (143 +/- 37) x 10(9)/L, which were significantly lower when compared with those at the 2nd to 4th week. Abnormal liver function was found in 27 cases (mostly with elevated serum ALT), with 70% occurred at the 3rd or 4th week. In terms of CT, 30 patients (73%) showed pathological changes in lungs, and bilateral lung involvement was found in 35.59%. Of 36 cases treated with steroids, 86% received middle or low dosage (80 - 240 mg/d). Artificial ventilation was used for twenty-seven patients, and air pipe mechanical ventilation was used for 1 case. Mortality in this study was 5%. CONCLUSIONS: Inertia and myalgia may be the earlier symptoms of health care workers with SARS include, which are parallel to CT manifestations. There is no objective index for the assessment of the severity of the disease at early stage. The medicine associated toxicities may be the main reason of liver lesions. damages. Middle or low dosage of steroid was reasonable to be used as early as possible.
