Incidental detection of hepatitis B and C viruses and their coinfection in a hospital-based general population in tertiary care hospital of Uttar Pradesh

Prevalence of viral hepatitis infection in India: A systematic review and meta-analysis

BACKGROUND

Nowadays, Viral Hepatitis can be comparable to the big three communicable diseases: tuberculosis, HIV/AIDS, and malarial infections. The main purpose of this study was to summarize the prevalence of viral Hepatitis in India from peer-reviewed articles published from February 2000 to February 2021.

MATERIALS AND METHODS

We conducted a systematic search on Science Direct, Scopus, Medline, PubMed, Web of Science, Google Scholar, and other open access journals. We evaluated all relevant papers that looked into the prevalence of viral Hepatitis systematically. Finally, 28 studies on viral Hepatitis published from February 2000 to February 2021 have been selected. These studies have been conducted across the northern, southern, central, eastern, and western regions of India.

RESULTS

Twenty-eight full-text publications were obtained and evaluated consisting of 45,608 research participants. Hepatitis A was found to range from 2.1% to 52.5%. Hepatitis B was found in a wide range of individuals, ranging from 0.87% to 21.4% of the population. Hepatitis C was found to range from 0.57% to 53.7%. The majority of the children were affected by hepatitis A, and 47.4% of third-trimester pregnant mothers were affected by hepatitis E. Diabetes, hospital admission, history of jaundice, history of surgeries, and heterosexual contact were the leading modes of acquiring HBV and HCV infections. As a result of its great magnitude, this disease poses a severe threat to the national healthcare system.

CONCLUSION

Effective public health measures are urgently needed to minimize the burden of viral Hepatitis and eliminate the disease.

Challenge of managing hepatitis B virus and hepatitis C virus infections in resource-limited settings

The global burden of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and coinfection represents a major public health concern, particularly in resource-limited settings. Elimination of HCV by 2030 has become foreseeable, with effective direct-acting antiviral oral therapies and the availability of affordable generics in low-and-middle-income countries (LMICs). However, access to oral nucleos(t)ide therapy for HBV remains critical and is limited outside the existing global HIV program platforms despite affordable prices. Prevention of mother-to-child transmission of HBV through scaling up of birth dose implementation in LMICs is essential to achieve the 2030 elimination goal. Most individuals living with HBV and/or HCV in resource-limited settings are unaware of their infection, and with improved access to medications, the most significant barrier remains access to affordable diagnostics and preventive strategies. The coronavirus disease 2019 pandemic interrupted hepatitis elimination programs, albeit offered opportunities for improved diagnostic capacities and raised political awareness of the critical need for strengthening health care services and universal health coverage. This review underpins the HBV and HCV management challenges in resource-limited settings, highlighting the current status and suggested future elimination strategies in some of these countries. Global efforts should continue to improve awareness and political commitment. Financial resources should be secured to access and implement comprehensive strategies for diagnosis and linkage to care in resource-constrained settings to fulfill the 2030 elimination goal.

Unsterile injection equipment associated with HIV outbreak and an extremely high prevalence of HCV-A case-control investigation from Unnao, India

The integrated counseling and testing center (ICTC) located in the district hospital, Unnao in the northern state of Uttar Pradesh (UP), India witnessed an increased detection of HIV among its attendees in July 2017. Subsequently, health camps were organized by the UP State AIDS Control Society in the villages and townships contributing to such detection. We conducted a case-control study to identify factors associated with this increased detection; 33 cases and 125 controls were enrolled. Cases were individuals, detected HIV sero-reactive during November 2017-April 2018 from three locations namely Premganj, Karimuddinpur and Chakmeerapur in the Bangarmau block of the district of Unnao. Controls hailed from the same geographical setting and tested HIV sero-nonreactive either in health camps or at ICTC centers from where the cases were detected. Misclassification bias was avoided by confirming HIV sero-status of both cases as well as controls prior to final analysis. Study participants were interviewed on various risk practices and invasive treatment procedures. They were also tested for HIV and other bio-markers reflecting unsafe injecting and sexual exposures such as hepatitis B surface antigen (HBsAg), anti-HCV antibody (HCV Ab), anti-herpes simplex-2 Immunoglobulin G (HSV-2 IgG) and rapid plasma regain (RPR) test for syphilis. Secondary data analysis on three time points during 2015 through 2018 revealed a rising trend of HIV among attendees of the ICTCs (ICTC-Hasanganj, ICTC-Unnao district hospital and ICTC- Nawabganj) catering to the entire district of Unnao. While there was a seven fold rise of HIV among ICTC attendees of Hasanganj (χ² value for trend 23.83; p < 0.001), the rise in Unnao district hospital was twofold (χ² value for trend 4.37; p < 0.05) and was tenfold at ICTC-Nawabganj (χ² value for trend 5.23; p < 0.05) indicating risk of infection prevailing throughout the district. Primary data was generated through interviews and laboratory investigations as mentioned above. The median age of cases and controls was 50 year (minimum 18 –maximum 68; IQR 31–57) and 38 year (minimum 18 –maximum 78; IQR 29–50) respectively. Thirty six percent of the cases and 47% of controls were male. A significantly higher proportion of cases (85%) had HCV Ab compared to controls (56%; OR 4.4, 95% CI 1.5–12.1); none reported injection drug use. However, cases and controls did not differ significantly regarding presence of HSV-2 IgG (6% versus 8% respectively). Neither any significant difference existed between cases and controls in terms of receiving blood transfusion, undergoing invasive surgical procedures, tattooing, tonsuring of head or skin piercing. In multivariate logistic regression model, ‘unsafe injection exposure during treatment-seeking’(AOR 6.61, 95% CI 1.80–24.18) and ‘receipt of intramuscular injection in last five years’ (AOR 7.20, 95% CI 1.48–34.88) were independently associated with HIV sero-reactive status. The monophyletic clustering of HIV sequences from 14 cases (HIV-1 pol gene amplified) indicated a common ancestry. Availability of auto-disabled syringes and needles, empowerment of the local communities and effective regulatory practices across care settings would serve as important intervention measures in this context.
