Possible Mode of Spread of Hepatitis B and Hepatitis C in Chronic Liver Disease Patients Presenting at CMH Lahore Medical College and Institute of Dentistry

Abstract

Introduction Chronic hepatitis B and C are the leading causes of chronic liver disease and a significant cause of mortality and morbidity worldwide. Hepatitis B is a preventable disease with vaccination, which is available worldwide. About 257 million people are affected worldwide with hepatitis B and around 71 million people with hepatitis C, and Pakistan is the second most prevalent country with hepatitis C. The possible mode of spread of hepatitis B and C in chronic liver disease patients presenting at CMH medical wards and dental clinics was evaluated. Among various types of hepatitis, A, B, and C are the most common. The course of disease followed by hepatitis A is short term, but when we talk about the common types, which are B and C, the disease is chronic and, moreover, the complications associated with these types are more severe too. Materials and methods The study was carried out at the medical wards and dental clinics of CMH Lahore Medical College. A total of 240 patients were evaluated for the possible mode of spread of hepatitis B and C. A detailed history regarding the use of needles, surgical procedures, including dental treatment, unsterilized razors for shaving (barbers'), blood transfusions, tattooing, and mode of delivery in females, was evaluated and data were interpreted. Aims and objectives To observe the mode of spread of hepatitis B and C among patients of CMH Lahore Medical College and Institute of Dentistry. Results The results of our study revealed that the most common mode of spread of disease in males was exposure to infected blades and instruments at barbers' shops. In females, blood transfusion and caesarian section, especially in rural areas, remained the most common possible cause of spread. A small number of patients was not aware of the possible mode of transmission, whereas a few others did not seek treatment for the disease. Conclusion From our study, we can conclude that a substantial number of patients with chronic liver disease have exposure to various risk factors. Exposure to the unsterilized equipment of barbers and improperly screened blood remains the main cause of the spread of hepatitis B and C in males whereas surgical procedures related to gynecological procedures and blood transfusions remain the second most common cause. Dental procedures in the hands of trained dental professionals/dentists carry less danger of transmitting the disease but carry an equally high incidence if quacks do the dental procedures.
