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.

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.

Serum cholinesterase: a potential assistant biomarker for hand, foot, and mouth disease caused by enterovirus 71 infection.

Infect Dis Poverty 2016 Mar 29;5:27. Epub 2016 Mar 29.

Clinical Laboratory Center, Anhui Provincial Children's Hospital, Hefei, 230051, China.

Background: Hand, foot, and mouth disease (HFMD) caused by enterovirus 71 (EV71) is a potentially life-threatening infectious disease that commonly occurs in children. Diagnosis of HFMD caused by EV71 largely depends on clinical manifestations and rare serological biomarkers used to identify children suffering from HFMD. Serum cholinesterase (SChE) activity has frequently been reported as a potential biomarker for solid central nervous system tumors, chronic heart failure, and liver cirrhosis. However, its potential value in the diagnosis of neurotropic virus infections, such as HFMD caused by EV71, remains to be determined.

Findings: In our study, 220 children hospitalized with HFMD caused by EV71, 34 inpatients infected with coxsackievirus A16 (CVA16), and 43 undefined enterovirus-infected HFMD inpatients were recruited at the Anhui Provincial Children's Hospital between January 2011 and December 2012. SChE activity was measured. The non-parametric Mann-Whitney U test showed that SChE activity in children diagnosed with HFMD caused by EV71 was significantly higher than in healthy controls (p < 0.001), as well as in children with upper respiratory tract infections (p = 0.011), bronchopneumonia (p < 0.001), septicemia (p < 0.001), amygdalitis (p < 0.001), and appendicitis (p < 0.001). In addition, higher SChE activity was observed in male inpatients with HFMD caused by EV71 (47.7 % positivity) compared to female inpatients (26.1 % positivity) (chi-square test, p = 0.002). In our study, no significant differences in SChE levels were observed among different ages (up to 120 months) (r = -0.112, p > 0.05). An important finding was that SChE activity declined in the recovery phase of HFMD caused by EV71 compared to the acute phase (p < 0.001).

Conclusions: Elevated SChE activity was observed in patients with severe HFMD caused by EV71. Therefore, SChE might be a potential assistant biomarker for the diagnosis of HFMD caused by EV71 in children.
