Nontyphoidal Salmonella (NTS) bacteremia is not rare in otherwise healthy children in Taiwan. Few studies described the clinical manifestations and outcomes of NTS bacteremia in previously healthy children.
Children with blood culture positive for NTS treated at Chang Gung Children's Hospital between May 1996 and June 2003 were identified from the microbiology logbook. Patients who had underlying events or concomitant diseases were excluded.
We evaluated 199 patients. One hundred and eighteen (59.3%) were male children and 184 (92.5%) were between 3 months and 5 years of age. Fever (97.0%) and diarrhea (79.9%) were the most common initial presentations. Leukocytosis (leukocyte >15,000/mm) and elevated serum C-reactive protein concentration (> or =10 mg/L) were present in 14.6% and 79.4% of the patients, respectively. Eighty-three percent of 184 patients with antibiotic treatment received a third- or fourth-generation cephalosporin as definitive antibiotic therapy. Focal suppurative infections were present in 5 children (2.5%) on initial evaluation, and included meningitis in 2 and osteomyelitis in 3. Neither metastatic complications nor clinically recurrent diseases were found during a follow-up period of at least 12 months after treatment. No fatalities occurred in this series.
In healthy children, NTS bacteremia was relatively benign and extraintestinal focal suppurative infections were infrequently seen. Less than 10 days of appropriate antibiotic treatment is probably adequate for those without a suppurative focus of infection.
非伤寒沙门菌(NTS)菌血症在台湾其他方面健康的儿童中并不罕见。很少有研究描述先前健康儿童中NTS菌血症的临床表现和结局。
从微生物学日志中确定1996年5月至2003年6月在长庚儿童医院接受治疗且血培养NTS阳性的儿童。排除有基础疾病或合并疾病的患者。
我们评估了199例患者。118例(59.3%)为男童,184例(92.5%)年龄在3个月至5岁之间。发热(97.0%)和腹泻(79.9%)是最常见的初始表现。分别有14.6%和79.4%的患者出现白细胞增多(白细胞>15,000/mm)和血清C反应蛋白浓度升高(≥10mg/L)。184例接受抗生素治疗的患者中有83%接受第三代或第四代头孢菌素作为确定性抗生素治疗。初始评估时有5名儿童(2.5%)存在局灶性化脓性感染,其中2例为脑膜炎,3例为骨髓炎。在治疗后至少12个月的随访期间未发现转移性并发症或临床复发病例。本系列中无死亡病例。
在健康儿童中,NTS菌血症相对良性,很少见到肠外局灶性化脓性感染。对于没有化脓性感染灶的患者,少于10天的适当抗生素治疗可能就足够了。
