Data on the study of the epidemiology of rotavirus infection in Leningrad

The results obtained in the study of rotavirus infection in Leningrad in 1984-1987 are presented. Enzyme immunoassay techniques were used for the examination of 4,715 children aged 0-14 years and 1,162 adults with diagnosed acute enteral infection of unknown etiology, as well as the control group of 556 of healthy children aged 0-6 years and 77 healthy adults. The rotavirus antigen was detected in 1.210 sick children (25.7%) and 133 sick adults (11.4%), as well as in 6 healthy children (1.1%), but not detected in healthy adults. The following epidemiological regularities of rotavirus infection were established: the highest sick rate among children aged 0-2 years and a low level of rotavirus carriership among healthy persons; the seasonal character of rotavirus infection, its outbreaks occurring in winter and the epidemic periods varying in their character and duration in different years; the prevailing role of rotaviruses in the development of winter rises of acute enteral infection of unknown etiology in the city among children aged 0-2 years. The problem of the respiratory syndrome in rotavirus diarrhea is discussed. The rotavirus antigen was detected in 39 out of 144 children (27%) with diagnosed acute respiratory virus diseases and in 4 out of 99 nasopharyngeal washings (4%) from diarrhea patients. Adenoviruses were shown to play an insignificant role in the etiology of diarrhea (10% of cases).     

沙市婴幼儿腹泻中检出3株C群轮状病毒

1987～1988年在沙市165份婴幼儿急性腹泻标本中,用PAGE法检出轮状病毒37株(22.4％),其中3株为少见的轮状病毒,此种病毒经电镜观察,具有典型轮状病毒的形态结构,ELISA证实该病毒不具有A群和B群轮状病毒的群特异性抗原。RNA电泳分析表明,其基因组由11个双链RNA片段组成,电泳图型特殊,呈4:3:2:2的排列模式。上述试验表明,该病毒为世界上罕见的C群轮状病毒。免疫电镜证实,该病毒能被病人恢复期血清所凝集,提示该病毒是腹泻病儿的致病因子。     

Prevalence of Clostridium spp. and Clostridium difficile in children with acute diarrhea in São Paulo city,Brazil

Species of Clostridium are widely distributed in the environment, inhabiting both human and animal gastrointestinal tracts. Clostridium difficile is an important pathogen associated with outbreaks of pseudomembranous colitis and other intestinal disorders, such as diarrhea. In this study, the prevalence of Clostridium spp. and C. difficile, from hospitalized children with acute diarrhea, was examined. These children were admitted to 3 different hospitals for over 12 months. Eighteen (20%) and 19 (21%) stool specimens from children with (90) and without (91) diarrhea respectively, were positive to clostridia. Only 10 C. difficile strains were detected in 5.5% of the stool samples of children with diarrhea. None healthy children (without diarrhea) harbored C. difficile. From these 10 C. difficile, 9 were considered as toxigenic and genotyped as tcdA+/tcdB+ or tcdA-/tcdB+, and 1 strain as nontoxigenic (tcdA-/tdcB-). They were detected by the citotoxicity on VERO cells and by the multiplex-polymerase chain reaction. Thirty clinical fecal extracts produced minor alterations on VERO cells. The presence of C. difficile as a probable agent of acute diarrhea is suggested in several countries, but in this study, the presence of these organisms was not significant. More studies will be necessary to evaluate the role of clostridia or C. difficile in diarrhoeal processes in children.     

小儿病毒性腹泻的临床预后及危险因素分析

目的:探讨小儿病毒性腹泻的临床预后及危险因素。方法:纳入病例是2018年1月至2019年12月本院收治的200例小儿病毒性腹泻患者,回顾性分析其临床资料,分析小儿病毒性腹泻的临床特点。根据疾病痊愈情况分组,将128例痊愈患者作为实验组,72例未痊愈患者作为参照组,Logistic分析小儿病毒性腹泻患者疾病痊愈的危险因素。结果:200例患者中,HAstV感染121例,占60.50%;HAD感染36例,占18.00%;HUCV感染15例,占7.50%;HRV感染10例,占5.00%;混合感染18例,占9.00%。HAstV类型病毒性腹泻患者临床症状以呼吸道症状、发热、呕吐为主;HAD类型病毒性腹泻患者临床症状以发热、呕吐为主;HUCV类型病毒性腹泻患者临床症状以呼吸道症状、发热为主;HRV类型病毒性腹泻患者临床症状以发热、呕吐为主;混合感染类型病毒性腹泻患者临床症状以呼吸道症状、发热、呕吐为主。年龄、中枢神经损害、心肌损害、近1 w是否接触过腹泻是小儿病毒性腹泻患者疾病痊愈的危险因素,P0.05。结论:小儿病毒性腹泻不同感染类型,临床症状各不相同。小儿病毒性腹泻患者预后与年龄、中枢神经损害、心肌损害、近1 w是否接触过腹泻有着极为密切的联系,应当引起临床重视与关注。     

Diarrhea caused by enterotoxigenic Bacteroides fragilis in children less than 5 years of age in Hanoi, Vietnam

Enterotoxigenic Bacteroides fragilis (ETBF) are considered as an emerging enteropathogen causing diarrhea in children. Eight hundred and thirty-six (836) children less than 5 years of age including 587 children with diarrhea and 249 age-matched controls were involved in the study. Within the group of children with diarrhea, 7.3% (43/587) ETBF was detected by immunoseparation in combination with polymerase chain reaction. The corresponding figure for the controls was 2.4% (6/249) (P<0.01). Within the diarrhea group, the prevalence was significantly higher in children older than 1 year of age. Three subtypes of ETBF isolates have been identified with the prevalence of 67.4%, 18.6%, and 16% for bft-1, bft-2, and a new bft, respectively. In the controls, two of the subtypes were identified, 5 bft-1 and 1 bft-2. More than half (55.8%) of the samples harboring ETBF also had other identified pathogens. The clinical symptoms of the single ETBF infection were not different from those of co-infections. This is the first study of the role of ETBF in children's diarrhea in Vietnam and it is concluded that this pathogen is an important causative agent of diarrhea in children in Hanoi, Vietnam.     

Identification of a Novel Picornavirus in Healthy Piglets and Seroepidemiological Evidence of Its Presence in Humans

In this study, we describe a novel porcine parechovirus-like virus (tentatively named PLV-CHN) from healthy piglets in China using 454 high-throughput sequencing. The complete genome of the virus comprises 6832 bp, encoding a predicted polyprotein of 2132 amino acids that is most similar to Ljungan virus (32% identity). A similar virus that belongs to a novel Picornaviridae genus, named swine pasivirus 1 (SPaV-1), was reported during the preparation of this paper. Sequence analysis revealed that PLV-CHN and SPaV1 shared 82% nucleotide identity and 89% amino acid identity. Further genomic and phylogenetic analyses suggested that both SPaV1 and PLV-CHN shared similar genomic characteristics and belong to the same novel Picornaviridae genus. A total of 36 (20.0%) fecal samples from 180 healthy piglets were positive for PLV-CHN by RT-PCR, while no fecal samples from 100 healthy children and 100 children with diarrhea, and no cerebrospinal fluid samples from 196 children with suspected viral encephalitis, was positive for the virus. However, Western blot and enzyme-linked immunosorbent assays using recombinant PLV-CHN VP1 polypeptide as an antigen showed a high seroprevalence of 63.5% in the healthy population. When grouped by age, the antibody-positivity rates showed that the majority of children under 12 years of age have been infected by the virus. It was suggested that PLV-CHN, SPaV1, or an as-yet-uncharacterized virus can infect humans early in life. Thus, investigation of the role of this novel virus is vital.     

123例腹泻患儿粪便中艰难梭菌毒素基因特征及感染危险因素分析

探讨腹泻患儿粪便中艰难梭菌毒素基因特征, 并分析产毒艰难梭菌感染的危险因素。

采集2019年1月至2021年3月嘉兴市第二医院儿科收治的腹泻患儿的粪便标本共123份, 其中社区获得性腹泻患儿60例, 医院获得性腹泻患儿63例。标本进行厌氧培养, 采用实时荧光PCR鉴定艰难梭菌tpi基因, 并检测tcd A、tcd B毒素基因。收集患儿临床资料, 采用Logistic回归分析产毒艰难梭菌感染的危险因素。

123例粪便标本共检出艰难梭菌tpi基因阳性35例(28.46%), 毒素基因中tcd A⁺ B⁺为19例(15.45%), tcd A⁺B^-为3例(2.44%), tcd A^-B⁺为2例(1.63%), tcd A^-B^-为11例(8.94%)。社区获得性腹泻患儿中tcd A/B产毒艰难梭菌感染率为28.33%, 高于医院获得性腹泻患儿的11.11%(P < 0.05)。产毒艰难梭菌感染腹泻患儿与非产毒艰难梭菌感染腹泻患儿的性别、年龄、居住地、是否早产、有无先天性疾病、既往有无胃肠道手术、抗生素应用种类、近1个月内有无机械通气、临床症状、血液白细胞计数、血红蛋白、粪便白细胞计数、血清C反应蛋白、血清白细胞介素-6、血清白蛋白、血肌酐、血清总胆红素水平比较差异无统计学意义(均P > 0.05)。产毒艰难梭菌感染腹泻患儿中的非母乳喂养、近1个月内抗生素用药史、抗生素持续用药时间 > 7 d、近1个月内糖皮质激素用药史、近1个月内抑酸药用药史、近1个月内肠内营养者的比例显著高于非产毒艰难梭菌感染腹泻患儿(均P < 0.05)。非母乳喂养(OR=2.433)、近1个月内抗生素用药史(OR=3.040)、近1个月内肠内营养(OR=2.330)是腹泻患儿产毒艰难梭菌感染的独立危险因素(均P < 0.05)。

嘉兴地区儿童艰难梭菌毒素基因主要为tcd A/B基因, 患儿以社区获得性腹泻为主, 非母乳喂养、抗生素用药史、肠内营养的儿童更容易感染艰难梭菌。

Effect of Women’s Perceptions and Household Practices on Children’s Waterborne Illness in a Low Income Community

An ecosystem approach to human health was adopted in a community-based study carried out in Bebnine, an underserved town in Lebanon. The objective of the study is to examine the association between women’s household practices and diarrhea among children in a setting where contaminated drinking water and intestinal diseases are common. A total of 280 women were randomly selected and interviewed using a structured questionnaire. Data were collected on 712 children between the ages of 6 and 14. The study instrument included determinants of diarrhea such as sociodemographic characteristics, water, sanitation, hygiene practices, gender variables, and behavioral risk factors. Multivariate regression analysis was employed to examine the association between water handling practices and diarrhea. The prevalence of diarrhea is 5%. Female children are more likely to suffer from diarrhea than male children (OR = 2.58; 95% CI: 1.19–5.62). Treatment of drinking water at the household level and the use of drinking water for cooking and the preparation of hot beverages are protective against diarrhea (OR = 0.15; 95% CI: 0.03–0.65). Female caretakers’ behaviors such as daily bathing and seeking medical care at times of illness are protective against diarrhea in children. The findings suggest that diarrhea is a gendered health problem. Female children, who are generally more involved in household activities than male children, are at higher risk of suffering from diarrhea. Female caretakers’ personal hygiene, household practices, and perceptions of diarrhea are additional risk factors. Intervention activities would be more effective if based on a better understanding of gender roles and household power relations.     

婴幼儿腹泻病原学及其快速诊断

目的探讨小儿腹泻标本病原学特点及流行病学特征,寻求小儿感染性腹泻的快速诊断方法。方法对我院2003年10月至2005年9月门诊及住院的1160例2个月-5岁腹泻患儿的腹泻标本进行细菌学检查及pH检测。结果(1)1160例患儿腹泻标本病原学阳性605例(52.16%),检出病原20种621株,外源性肠道病原菌、内源性肠道条件致病菌以及轮状病毒3种病原构成比依次为35.75%、32.69%、31.56%。主要病原:(1)轮状病毒196株(31.56%),志贺菌118株(19.00%),克雷伯菌86株(13.8%),枸橼酸杆菌67株(10.79%),致泻性大肠埃希菌60株(9.66%)。(2)1160例患儿腹泻标本6个月-2岁患儿占881例(69.91%)。轮状病毒腹泻多发于秋冬季、大便为水样、多见于2岁以内婴幼儿,志贺菌以夏秋季与脓血便检出率较高。(3)病原菌分离阳性腹泻标本pH>7占明显优势,轮状病毒阳性标本、病原检查阴性标本、健康体检对照标本pH<6占明显优势,前者pH与后三者pH统计学比较,差异有高度显著性(P<0.01)。结论引起小儿腹泻的病原种类繁多,轮状病毒居首位,内源性肠道条件致病菌在腹泻标本中的构成比已接近外源性肠道致病菌而成为腹泻的重要病原菌,大便pH可作为急性腹泻病早期简单、快速、准确、价廉的初步诊断及合理应用抗生素的重要指标。

目的探讨酪酸梭菌活菌散联合葡萄糖酸锌治疗儿童急性腹泻的疗效。方法选取急性腹泻患儿76例,随机分为观察组和对照组各38例。两组患儿均予以调整饮食、口服或静脉补液和纠正水电解质酸碱失衡紊乱等常规治疗。观察组患儿予以酪酸梭菌活菌散和葡萄糖酸锌联合治疗,对照组患儿予以单纯酪酸梭菌活菌散治疗。观察两组患儿治疗后主要症状和体征改善的时间,并比较其临床疗效及治疗后3个月内腹泻的复发率。结果观察组患儿治疗后的止泻、呕吐、腹痛和粪常规等恢复正常时间均明显短于对照组（P〈0.05）;同时治疗3 d后,观察组患儿临床总有效率为94.74%,明显高于对照组的78.95%（χ2=4.15,P〈0.05）。两组患儿治疗后随访3个月,其中观察组和对照组分别腹泻复发5例（13.16%）和13例（34.21%）,观察组腹泻的复发率明显低于对照组（χ2=4.66,P〈0.05）。结论酪酸梭菌活菌散联合葡萄糖酸锌治疗儿童急性腹泻的疗效较肯定,能明显改善患儿腹泻症状,缩短腹泻病程,并能减少腹泻的复发。     

Estimation of serum zinc and copper in children with acute diarrhea

Diarrhea is, in reality, as much a nutritional disease as one of fluid and electrolyte loss. Children who die from diarrhea, despite good management of dehydration, are usually malnourished and often severely so. In this study, we determined the serum levels of zinc and copper before and after standard oral rehydration solution (ORS) therapy in children with acute diarrhea and correlated it with diarrheal duration and severity. One hundred ten children suffering from acute diarrhea were included. Serum zinc and copper levels of these children were estimated at the time of enrollment and after treatment with standard ORS therapy. This study shows that children suffering from acute diarrhea show a statistically significant decrease of 13.1% and 12.8% in serum zinc and copper concentrations, respectively, compared to normal. These levels further decrease by 22.6% and 22.4%, respectively, after treatment with standard ORS therapy. Our study shows that children with the lower plasma zinc and copper levels suffered with more severe and longer duration of diarrhea. Zinc and copper supplementation could be added to standard ORS therapy for the reduction in morbidity and mortality associated with acute diarrhea in children.     

苏浙闽地区婴幼儿急性腹泻患者病毒检测及临床特征分析

目的 分析苏浙闽地区婴幼儿急性腹泻患者常见病毒及患儿临床特征,为婴幼儿急性腹泻的流行病学研究和临床治疗提供参考。方法 选取2010至2014年苏浙闽地区多家医院门诊就诊的急性腹泻患儿1 452例,采用ELISA法检测A组轮状病毒（HRV）,多重PCR法检测诺如病毒（NoV）、肠道腺病毒（EAdV）和星状病毒（HAstV）,并用RT-PCR法对A组轮状病毒阳性的样本进行G和P分型。结果 1 452例患儿中由常见病毒引起的急性腹泻患儿有707例,占总调查患者的48.69%。急性腹泻患儿常见病毒感染中单一病毒感染占90.10%（637/707）,其感染病毒的构成以轮状病毒最多（47.52%,336/707）,其次为诺如病毒（36.07%,255/707）以及星状病毒（2.40%,17/707）和肠道腺病毒（4.10%,29/707）。病毒感染腹泻患儿中多重感染者共70例,占9.90%（70/707）,以A组轮状病毒合并诺如病毒感染最为常见,占多重感染者的68.57%（48/70）。226份A组轮状病毒阳性标本中,G分型以G1为优势分型,占33.19%;P分型中则以P[11]比例最高,占38.50%;G、P型组合以P[11]G11为主（38.50%）。结论 A组轮状病毒是引发婴幼儿急性腹泻的主要病毒,诺如病毒次之,且婴幼儿病毒性腹泻患者可合并多种病毒感染。不同地区腹泻患儿病毒感染阳性率有差异,轮状病毒基因型表现则具有多样性。
