Shrivastava: Incidence of hepatitis B and hepatitis C in Pediatric ward in General hospital, Bhopal (M.P)


Introduction

Hepatitis B and HCV infections can lead to an acute or silent course of liver disease, progressing from liver impairment to cirrhosis and decompensated liver failure or hepatocellular carcinoma (HCC) in a 20-30 years period. In addition, HBV and HCV infection rate differ in different settings, and prognosis may be worse in conjunction with schistosomiasis, malaria, and HIV in other Indian populations.1

Viral hepatitis caused by HCV and HBV represents a major public health problem in India. These viruses share common modes of transmission, such as parenteral routes2 Hepatitis B is a viral infection of the liver and is a serious global health problem with a high risk of death from cirrhosis and liver cancer, a disease that killed about one million persons each year. Globally, of the two billion people who have been infected with HBV more than 350 million have a chronic infection.3

HBV is endemic in Senegal. According to many data, the prevalence of this infection in the adult population is up to 85%. Young children are a victim of the intensive circulation of this virus. Indeed, the risk of becoming a chronic carrier which can further lead to HCC is related to the age at which the infection had been contracted.4

A growing body of evidence indicates that HIV positive individuals are more likely to be infected with HBV than HIV negative individuals, possibly as a result of shared risk factors. There is also evidence that HIV positive individuals who are subsequently infected with HBV are more likely to become HBV chronic carriers, have a high HBV replication rate with HBeAg positive for a much longer period. In addition, it is evident that immunosuppression brought about by HIV infection may cause reactivation or reinfection in those previously exposed to HBV. Furthermore, HIV infection exacerbates liver disease in HBV co-infected individuals, and there is an even greater risk of liver disease when HIV and HBV co-infected patients are treated with highly active antiretroviral therapy (HAART).5

The tropical features of HCV have not yet been fully elucidated due to the scarcity of data. However, it has been estimated that two-thirds of the infected population lives in the tropics. The most heavily affected regions are Africa, China and South East Asia with a prevalence rate of 5.3%, 3.0% and 2.4% respectively. In several countries mostly in Africa, prevalence rates range from 5% to 10% or higher.6

The outcome of HCV infection acquired in childhood is uncertain because of the diversity of the epidemiological and clinical features of infection and disease.7

The natural history of HCV infection has a highly variable course. Many patients develop chronic infection, with the consequent risk of cirrhosis, liver failure and HCC. The disease progression is influenced by certain factors such as duration of infection, age, sex, co-infection with HBV, EBV, CMV. The level of HCV viremia and its type. Other endemic infections in the community as bilharziasis may have a role in the progression of the condition to serious complication. These factors are correlated with newly proposed grades and stages of the disease.8

Materials and Methods

Hospital based study of pediatric cases admitted to Rajeev Gandhi College and General Hospital Bhopal during a period from March 2019 to February 2020. Pediatric cases were studied for the incidence of HBsAg and HCV Ab by ELISA, Rapid technique. A total of 1877 pediatric cases admitted to the hospital during a period from March 2019 to February 2020. From the total admission, only 25 cases (1.3%) were presented with clinical hepatitis (jaundice, hepatomegaly and raised liver enzymes).

Results

All 25 cases further tested for HBsAg as well as HCV antibody. There were 12 cases of positive HBV (0.65) of the total admission and (48%) of the hepatitis cases, of these 6 were male (50%) and 6 female (50%). In the case of HCV only 2 cases are found to be positive (8%) of hepatitis cases. The distribution of HBV and HCV during the period of study shown. While the age distribution of HBV cases shown in Table 1 and the geographical distribution of acute hepatitis cases (50%) out of 12 cases of HBV in the adolescent age group. 2 cases (8%) of acute hepatitis was expired and 1 HBV and the rest were HCV infection.

Discussion

Viral hepatitis caused by HBV and HCV represents a major public problem worldwide.1, 2, 9 Chronic infections with HBV and HCv are the most important risk factors for the developments of HCC in humans. HBV is the primary cause of HCC in high-risk area including China and Africa, whereas in developed countries such as United States, HCV plays a more prominent role and is at least partially responsible for the increase in HCC incidence in this country.10 In the present study, 12 cases of HBV and 2 cases of HCV out of 25 cases who represented with acute hepatitis from a total of 1877 pediatric cases were submitted. The pediatric were aged between (1mths-15 years) and 50% of the patients were male and 50% females in HBV and HCV cases.

Several studies found similar results. Prevalence of HBV and HCV in the population of blood donors in Georgia has been investigated, out of 4970 donors 7% had anti- HCU (6.9% confermed), HBsAg was positive in 4.1% (3.4% confirmed.11

Hepatitis markers (HBV and HCV) in primary school children in Freetown, Sierra Leone was investigated in a government school, 12 pupils of the 450 were positive for HBsAg (males g, females 3), while HCV were detected in one case of children.12

In contrast to these studies Triki, et al.13 showed the high prevalence of HBV infection in Tunisia, it occurs mainly in children and teenagers, and vertical and perinatal transmission of HBV does not appear to be significant. While sero-prevalence of HCV in the Tunisian general population was low (0.4%). Among the Canadian Inuit, the prevalence of HBV infection is 5% while serological evidence of HCV infection is more common in the Canadian Inuit and first nations. (1% - 18%) than the remainder of Canadian population (0.5% - 2%), so viral hepatitis is common in the Canadian Inuit and first nations populations.9 There is locally reported study by Saleh, et al.14 finding that 21 (7.9%) of the 266 subject had evidence of HCV infection indicates that there is a very high frequency of community – acquired “HCV in the normal Libyan population, and this has major implication for blood transfusion in that country. It is known that the prevalence of HBV and HCV infections vary according to geographical areas. However in Russia, HBV infection is widespread and have led to a high incidence of acute and chronic liver diseases among children in this region.15

Hepatitis is common in the Stann Greek District of Southern Belize, especially acute hepatitis B.16 Viral hepatitis observed in Cambodia and Vietnam to improve the control measures against viral hepatitis in the public health programs.17

In this study the cases of male are equal to female in both HBV and HCV. As well as the incidence of HBV are higher than HCV, while the incidence of both HBV and HCV are low. Among 25 cases of acute hepatitis, 12 cases 48% where hepatitis B, and 8% where hepatitis C. although no large population study of Indian children is available, hepatitis B probably accounts for about 30% of cases while hepatitis C is found in approximately 20%9 showing higher incidence of hepatitis B in children and higher incidence of hepatitis C in Indian children.

Conclusion

This study shows low incidence rates of HBV and HCV infections in Bhopal city. Hepatitis is a major health hazard problem, as both viruses are potentially avoidable if hepatitis precautions rules are practiced strictly and regularly in Bhopal city. Increased knowledge about the routes of viral infection among both doctor’s staff and patients by regular educational sessions can also help in avoiding this health hazard problem. Also, active programs need to be controlled in the spreading of such infections, in the population at large. The use of viral screening programs must include and the available HBV vaccination.

Limitations

While HCV Ab positive cases by ELISA, need further confirmation using PCR test and the possibility of liver biopsy as some of them may need and benefit from interferon treatment. Upon identification effective prophylaxis should be introduced and maintained.
