To study clinical characteristics of pediatric SARS cases in Beijing.
Eighteen pediatric cases with SARS diagnosed on admission were analyzed. The cases were admitted to Beijing Children's Hospital and Ditan Hospital (pediatric ward) from April 8 to May 12.
The 18 children aged 5 months to 15 years (10 male and 8 female) had epidemiologically linked findings. Fourteen cases had close contact with SARS patients. Four cases were living in the community where adult SARS patients were found. All the 18 patients but one presented with fever and cough. Most of them had high fever, 2 cases had bradycardia, 2 had diarrhea, and another 2 had tachypnea. Malaise and headache were noted only in 3 cases respectively which were much less frequently seen than in adult patients. Symptoms and signs of the children were much less severe and aggressive than adults cases. Thirteen children had chest radiographic consolidation. Of them, 9 cases had progressive changes after admission, then improved quickly. We did not find significant lower hemoglobin and platelet levels. Most patients had leukopenia and lymphopenia. Serologic test was performed for 15 cases and 8 were positive for SARS virus-IgG and 6 for IgM antibody. Of the 4 cases who had close contact with SARS adults and without chest radiograph abnormal findings, 3 were negative for SARS virus-antibodies. Part of the patients had temporary abnormality of myocardial enzyme and liver function. All these children finally had rapid improvement on chest radiograph. The patients were treated with antiviral agents and corticosteroid. Only two cases required oxygen therapy. No child needed assisted ventilation and no death, nor lung fibrosis occurred. After hospitalization, all patients were improved and discharged when this paper was being written. The average hospital stay of these patients was 14.6 days (6 - 22 days).
Compared with adults, pediatric SARS patients seemed to have their own clinical characteristics. The disease in children had lower severity and infectivity than that in adults. The mechanisms of the disease in children should be studied in well-designed clinical trials. Cases like the 4 children who had close contact with SARS adult patients but without chest radiographic changes deserve further studies with the help of more reliable and sensitive etiologic tests.
研究北京儿童SARS病例的临床特征。
分析18例入院时确诊为SARS的儿童病例。这些病例于4月8日至5月12日被收入北京儿童医院和地坛医院(儿科病房)。
18名儿童年龄在5个月至15岁之间(男10例,女8例),有流行病学关联证据。14例与SARS患者有密切接触。4例居住在发现成人SARS患者的社区。18例患者中除1例外均有发热和咳嗽症状。多数患儿有高热,2例有心动过缓,2例有腹泻,另2例有呼吸急促。分别仅有3例出现乏力和头痛,其发生率远低于成人患者。儿童的症状和体征比成人患者轻得多,病情进展也不那么迅猛。13名儿童胸部X线片有实变。其中9例入院后有病情进展,随后迅速好转。未发现血红蛋白和血小板水平明显降低。多数患者有白细胞减少和淋巴细胞减少。对15例进行了血清学检测,8例SARS病毒IgG抗体阳性,6例IgM抗体阳性。4例与SARS成人密切接触且胸部X线片无异常发现的患儿中,3例SARS病毒抗体检测为阴性。部分患者心肌酶和肝功能有一过性异常。所有这些患儿胸部X线片最终均迅速好转。患者接受抗病毒药物和糖皮质激素治疗。仅2例需要吸氧治疗。无患儿需要机械通气,无死亡病例,也未发生肺纤维化。住院后,所有患者病情均有改善,撰写本文时均已出院。这些患者的平均住院时间为14.6天(6 - 22天)。
与成人相比,儿童SARS患者似乎有其自身的临床特征。儿童SARS病情严重程度和传染性低于成人。儿童SARS的发病机制应通过精心设计的临床试验进行研究。像4例与SARS成人密切接触但胸部X线片无改变的儿童病例,值得借助更可靠、更敏感的病原学检测进行进一步研究。
