Department of Infectious Diseases, Children's Hospital of Fudan University, Shanghai, China. Electronic address:

Objectives: The treatment of acute herpangina is inconsistent. We aim to evaluate the effectiveness and safety of interferon α-2b spray versus Ribavirin for the disease.

Methods: A randomized, controlled trial was conducted in eight hospitals in China between 2016 and 2018. 668 patients (1-7 years old) were randomized into experimental group (treated with Interferon α-2b spray) or control group (received Ribavirin Aerosol). Body temperature returned to normal within 72 hours and remained for 24 hours was the primary outcome; release of oral herpes and adverse events were the secondary outcomes.

Results: (1) The average age of onset was 2.5 years old. (2) After 72 hours' treatment, body temperature of 98.5% patients in experimental group and 94.3% in control group returned to normal and lasted for 24 hours (P = 0.004). The differences were greater at 48 hours' treatment (95.2% vs. 85.9%, P < 0.001) and at 24 hours (77.5% vs. 66.5%, P = 0.001). (3) The rate of improved oral herpes in experimental group were higher than that in control group (46.7% vs.37.1%, P = 0.011). No adverse reaction occurred.

Conclusions: Local application of recombinant interferon α-2b spray showed better efficacy for acute herpangina in children. It was safe for use.

Postoperative multidrug-resistant meningitis successfully treated with intravenous doxycycline and intraventricular gentamicin: A case report.

World J Clin Cases 2019 Dec;7(24):4342-4348

Department of Infectious Diseases, Children's Hospital of Fudan University, Shanghai 201102, China.

Background: Multidrug-resistant (MDRAB) has emerged as an increasingly important pathogen that causes nosocomial meningitis. However, MDRAB-associated nosocomial meningitis is rarely reported in children.

Case Summary: We report the case of a 1-year-old girl with a choroid plexus papilloma, who developed postoperative nosocomial meningitis due to MDRAB. The bacterial strain was sensitive only to tigecycline and colistin, and showed varying degrees of resistance to penicillin, amikacin, ceftriaxone, cefixime, cefotaxime, ciprofloxacin, levofloxacin, gentamicin, meropenem, imipenem, and tobramycin. She was cured with intravenous doxycycline and intraventricular gentamicin treatment.

Conclusion: Doxycycline and gentamicin were shown to be effective and safe in the treatment of a pediatric case of MDRAB meningitis.

Efficacy and safety of interferon alpha-2b versus pegylated interferon alpha-2a monotherapy in children with chronic hepatitis B: a real-life cohort study from Shanghai, China.

World J Pediatr 2019 Dec 5;15(6):595-600. Epub 2019 Sep 5.

Department of Infectious Diseases, Children's Hospital of Fudan University, Shanghai, 201102, China.

Background: Interferon alpha (IFN-α) is a preferred therapy for antiviral treatment of children with chronic hepatitis B (CHB) aged > 1 year currently. Peginterferon alpha-2a (Peg-IFN α-2a) is a recommended international guideline for treatment of CHB children, which is limited to children aged > 3 years. But the exact efficacy and safety of IFN-α and Peg-IFN α-2a for treating CHB are not sufficient.

Methods: Clinical manifestations, baseline characteristics, related laboratory tests and adverse events were retrospectively analyzed in children with CHB, who visited Children's Hospital of Fudan University and were treated with IFN α-2b or Peg-IFN α-2a monotherapy and followed up from January 2003 to October 2018.

Results: A total of 36 immune-active patients without advanced fibrosis were enrolled to be treated with IFN α-2b (group A, n = 18) or Peg-IFN α-2a (group B, n = 18). IFN α-2b or Peg-IFN α-2a was administered for a median of 48 weeks subcutaneously by body surface area (BSA) category at a dose of 3 MU/m or 104 μg/m, respectively. HBV e antigen (HBeAg) seroconversion rates at 48 weeks post-treatment were higher in group A than group B (92.9% vs. 87.5%), so as the rates of HBsAg clearance (22.2% vs. 11.1%), and hepatitis B virus (HBV)-DNA < 1000 IU/mL (88.9% vs. 83.3%). Only mild flu-like symptoms and transient neutropenia appeared in some children at the early stage of treatment. No severe abnormal results was observed in other laboratory assessments.

Conclusion: The antiviral monotherapy of 48-week IFN α-2b or Peg-IFN α-2a in children with CHB is well tolerated and effective, which is associated with higher rates of HBeAg seroconversion and HBsAg clearance than in adults and previously pediatric patients.

Diagnosis and treatment of herpangina: Chinese expert consensus.

World J Pediatr 2020 Apr 25;16(2):129-134. Epub 2019 Jul 25.

Infectious Disease Diagnosis and Treatment Center, Beijing Ditan Hospital Capital Medical University, Beijing, China.

Background: Herpangina is a common infectious disease in childhood caused by an enterovirus. This consensus is aiming to standardize and improve herpangina prevention and clinical diagnosis.

Methods: The Subspecialty Group of Infectious Diseases, the Society of Pediatric, Chinese Medical Association and Nation Medical Quality Control Center for Infectious Diseases gathered 20 experts to develop the consensus, who are specialized in diagnosis and treatment of herpangina.

Results: The main pathogenic serotypes of herpangina include Coxsackievirus-A, Enterovirus-A and Echovirus. Its diagnosis can be rendered on the basis of history of epidemiology, typical symptoms, characteristic pharyngeal damage and virological tests. The treatment is mainly symptomatic, and incorporates topical oral spray with antiviral drugs. The course of herpangina generally lasts 4-6 days with a good prognosis.

Conclusion: The consensus could provide advices and references for the diagnosis, treatment and management of herpangina in children.

A case report of hepatic abscesses with soft tissue infection caused by methicillin resistant Staphylococcus aureus in a young child.

Medicine (Baltimore) 2017 Dec;96(50):e9260

Department of Infectious Diseases Department of Nosocomial Infection Control Clinical Microbiology Laboratory, Children's Hospital of Fudan University, Shanghai, China.

Rationale: Pyogenic hepatic abscess in children is a rare clinical condition. Hepatic abscesses caused by methicillin resistant Staphylococcus aureus are extremely rare.

Patient Concerns: A 6-year-old boy was referred to a tertiary children's hospital for a 6-day history of right lower abdominal pain and fever. Radiographic findings showed hepatic abscesses and soft tissue abscesses around the left femur.

Diagnoses: Bacteriology of blood, hepatic abscesses, and soft tissue abscesses showed methicillin resistant Staphylococcus aureus.

Interventions: Our patient received adequate drainage of MRSA abscesses and a complete course of antibiotics.

Outcomes: The hepatic abscesses were healed and no recurrence has been founded until now.

Lessons: This report describes an extremely rare case of hepatic abscesses with soft tissue infection caused by MRSA. Adequate drainage and appropriate systemic antibiotics should be considered as a standard treatment of MRSA abscesses in order to reduce the mortality rate and improve the quality of life.

[Profiles of innate immune receptors and cytokines in peripheral blood mononuclear cells in children with measles].

Zhonghua Er Ke Za Zhi 2013 Dec;51(12):898-902

Email:

Objective: The aim of this study was to explore the roles and clinical significance of innate immune receptors and cytokine in children with measles.

Method: The children with measles hospitalized in the department of infectious diseases, Children's Hospital of Fudan University during 2009-2011 were enrolled into measles group, while the healthy children examined in well baby clinic were enrolled into control group. The mRNA expression of TLR2/3/4/7, melanoma differentiation-associated gene-5 (MDA-5), retinoic acid-inducible gene I (RIG-I), IFN-α/β and IL-10 in peripheral blood mononuclear cells were detected by real-time PCR. The protein levels of IFN-α, IFN-β and IL-10 in plasma were measured using ELISA. SPSS 13.0 software was applied to analyze the difference between two groups.

Result: Data from a total of 98 patients in measles group and 59 children in control group were collected. The mRNA expressions of TLR2, MDA-5 and RIG-I had no statistical significance between two groups (P > 0.05, respectively). The relative mRNA expressions of TLR3, TLR4, TLR7 in measles group (2.25 ± 0.74, 2.05 ± 0.72, 2.12 ± 0.29) were significantly lower than those in control group (2.09 ± 0.78, 1.90 ± 0.75, 1.87 ± 0.68) (P < 0.01; respectively). Both IFN-α and IFN-β had significantly decreased mRNA expressions in measles patients (2.41 ± 1.31, 2.47 ± 1.26) compared with those in controls (2.22 ± 0.48, 2.35 ± 0.64)(P < 0.01 respectively); however, IL-10 mRNA levels significantly increased (2.49 ± 0.58 vs. 2.62 ± 0.95) (P < 0.001). The IL-10 levels in plasma in measles group were significantly higher during the whole period of fever [<5 d group: 29.89 (25.82-38.15) ng/L and ≥ 5 d group:34.55 (28.26-38.70) ng/L] than that in control group [25.15 (24.20-27.38) ng/L] (P < 0.05 respectively).

Conclusion: TLR3/4/7 mRNA expression was low in peripheral blood mononuclear cells of measles patients. Levels of IL-10 were significantly raised in the early stage after infection and lasted for a long time, and reduced IFN-α levels in plasma were associated with the fever durations of measles patients. These results indicated that multiple TLRs and cytokines may participate in the immune response after measles virus infection.

[Detection of class I integron and its relation to antimicrobial resistance of Shigella flexneri in children].

Zhonghua Er Ke Za Zhi 2006 Sep;44(9):680-3

Department of Infectious Diseases, Laboratory of Bacteriology, Children's Hospital of Fudan University, Shanghai 200032, China.

Objective: To investigate class I integron of Shigella flexneri, its prevalence in children, and its relation to bacterial resistance to antimicrobial agents.

Methods: Totally 51 strains of Shigella flexneri were isolated from fecal samples of children suffering from bacterial diarrhea seen between June 2004 and November 2004 at Children's Hospital of Fudan University. Polymerase chain reaction (PCR) was employed to amplify various integron markers, including intI1, gene cassette region and 3' conserved region of class I intrgron; susceptibility of Shigella flexneri strains to 7 antimicrobial agents was determined by K-B (Kriby-Bauer) method.

Results: Forty-six strains of Shigella flexneri had intI gene with a positive rate of 90.2% (46/51); 24 strains of Shigella flexneri were positive for qacEDelta1-sul1, the positive rate was 47.1% (24/51); proportion of the isolates positive for all the three regions of class I integron was 43.1% (22/51); 46 strains of intI positive Shigella flexneri were all positive for ant (3'')-I. Among 46 strains of intI positive isolates, proportions of the isolates positive and negative for qacEDelta1-sul1 were 47.8% (22/46) and 52.2% (24/46), respectively. In the class I integron positive Shigella flexneri, the resistance rates of ampicillin (chi(2) = 10.13, P < 0.01) and chloramphenicol (chi(2) = 19.97, P < 0.01) were significantly higher than those in the class I integron-negative group.

Conclusions: Class I integron was detected in 90.2% of Shigella flexneri in children; carriage of class I integron is related to antimicrobial resistance of Shigella flexneri.
