Evaluation of pediatric patients with hepatitis A

Atypical manifestations of acute viral hepatitis A in children in Bangladesh: Are these really uncommon?

BACKGROUND/AIM

The aim of this study was to find out the clinical spectrum of acute viral hepatitis A (AVH-A) infection in children, the relationship between atypical manifestations and laboratory findings and the outcome of patients with typical and atypical hepatitis A virus (HAV) manifestations.

METHODS

From January 2018 to September 2019, consecutive children (<18 years of age) with features suggestive of AVH with positive IgM anti-HAV both from inpatient and outpatient services were included in this study. Detailed history, physical findings, and investigations were recorded in the study questionnaire. Patients were followed up weekly until complete recovery. The Statistical Package for the Social Sciences (SPSS) version 22 was used for statistical analysis.

RESULT

The mean age of 200 children who were finally included in the study was 8.3±3.5 years with male to female ratio of 134:66. Atypical features were present in 30 (15%) children; prolonged cholestasis (17, 8.5%), ascites (12, 6%), pleural effusion (4, 2%), thrombocytopenia (2, 1%), and hemolysis (1, 0.5%) were observed. Pruritus (p=0.005), higher serum total and direct bilirubin (p=0.00 and 0.001 respectively), and lower serum albumin (p=0.01) levels were statistically significant in children with atypical manifestations. Moreover, this group had prolonged mean duration of jaundice and hospital course (p=0.00 and 0.083 respectively).

CONCLUSION

Atypical manifestations such as prolonged cholestasis and ascites are not uncommon in children with AVH-A in developing countries and seen in almost one-sixth of patients.

Need for recognizing atypical manifestations of childhood sporadic acute viral hepatitis warranting differences in management

Various atypical manifestations have been described in acute viral hepatitis (AVH). We evaluated the prevalence, clinical features, response to treatment and outcome of various atypical manifestations of AVH in children. Consecutive children (≤ 18 years) with AVH due to hepatitis A, B, or E were studied while patients with acute or acute on chronic liver failure were excluded. Diagnosis of atypical manifestations was based on standard criteria. A total of 477 children with AVH (median age 7.0 (5-11) years, 74% boys) were seen; 22% (n = 106) had atypical manifestations. Prolonged cholestasis was the most common (11%), followed by ascites (7%), intravascular hemolysis (3%), relapsing hepatitis (2%), acute pancreatitis (1.3%), and thrombocytopenia (0.7%). Atypical manifestations were more common in HAV as compared to HBV (30% vs. 3%, p = 0.00) and HEV (30% vs. 15%, p = 0.07). Prolonged cholestasis was significantly more common in older children (20% in > 10 years vs. 9% in 6-10 years ; p = 0.009 and 5% in 0-5 years of age [p < 0.000]). Ascites was more common in younger children, although not significant. All patients recovered with supportive treatment.Conclusions: Twenty-two percent of children with AVH have atypical manifestations, more often with HAV infection, and prolonged cholestasis is most common. Recognition of these manifestations ensures correct diagnosis and treatment. What is Known: • Acute viral hepatitis is a major public health problem in developing countries. • There is limited information about atypical manifestations which may lead to unnecessary investigations, delayed diagnosis and morbidity. What is New: • Atypical manifestations are common in children, seen most often with HAV infection, and prolonged cholestasis is most common. • Prompt recognition of these manifestations helps in early diagnosis, appropriate management, and preventing unnecessary investigations. • Ensure follow-up until complete recovery and not to miss underlying chronic liver disease.

Acute hepatitis A is the chief etiology of acute hepatitis in Egyptian children: a single-center study

Acute hepatic illness is an important health issue in children. Our work aimed to determine the prevalence of viral hepatitis in symptomatic children. It is a prospective cohort study of 268 children presented with acute hepatitis. Complete blood count, liver panel, and anti-hepatitis A virus (HAV) IgM were done initially. Cases negative for HAV were tested for anti-hepatitis E (HEV) IgM, anti-Epstein-Barr virus viral capsid antigen (EBV VCA) IgM, anti-cytomegalovirus virus IgM, hepatitis B surface antigen, anti-hepatitis B core IgM antibody, and anti-HCV antibody. Anti-HCV was repeated after 12 weeks to exclude seroconversion. In cases with negative viral serology, ceruloplasmin, total immunoglobulin G, antinuclear antibody, and abdominal ultrasound were done. Follow-up visits were bimonthly till recovery, then after 6 months. The mean age ± SD was 7.1 ± 3.7 years (1.5-18), and 56% were males. Acute HAV infection was diagnosed in 260 (97%) of cases and acute EBV infection in one case (0.4%). HAV/HEV coinfection was excluded in 70 HAV-positive cases. Six (2.2%) children remain undiagnosed and one child lost follow-up. About 80% of HAV-cases had normal laboratory results within 45 days. Unusual presentation of HAV infection was noticed in six children: four (1.5%) were relapsing, one had a cholestatic course, and one case had severe hemolytic anemia. Acute HAV infection was the chief etiology of acute hepatitis in our Egyptian children. The majority of the presentations were mild and children recover within a few weeks. An unusual pattern of HAV in children can be observed in endemic areas.
