Changing trends in the incidence and spectrum of cancers between 1990 and 2021 among HIV-infected patients in Busan, Korea.

Background: Long-term follow-up data on cancer incidence and spectrum among human immunodeficiency virus (HIV)-infected individuals in Korea have been scarce.

Material And Methods: This retrospective cohort study included HIV-infected individuals visiting a tertiary care hospital in Busan, South Korea between 1990 and 2021. The observation was divided into 4 periods.

Ten-Year Trends of Hepatitis A Seroprevalence in People Living with HIV in Korea.

Epidemiological information on hepatitis A among people living with HIV (PLHIV) in Korea is scarce. This retrospective study was performed at a tertiary care hospital and included 756 PLHIV with anti- hepatitis A virus (HAV) IgG tests. Between 2012 and 2021, the age at anti-HAV IgG seroconversion is gradually delayed, and the proportion of individuals susceptible to HAV infection increased among adult PLHIV in Korea.

Seroprevalence of Helicobacter pylori in human immunodeficiency virus-infected patients in a tertiary care hospital in Busan, South Korea.

Introduction: Human immunodeficiency virus (HIV) infection management has recently become more successful. While the life expectancy of HIV-infected patients increased, the prevalence of non-acquired immunodeficiency syndrome-defining cancers, such as gastric cancer, also increased. Helicobacter pylori is associated with gastric cancer, the most common cancer and the fourth leading cause of cancer-related deaths in South Korea, which has the highest incidence of chronic gastric mucosa inflammation.

Influence of Vitamin D Deficiency on the Development of Opportunistic Infection in People Living with HIV/AIDS (PWHAs).

Background: It is known that vitamin D is associated with immune cell growth, and an association between vitamin D deficiency and development of chronic infections such as tuberculosis has been reported. However, there have been few studies concerning the association between vitamin D deficiency and opportunistic infection (OI) in people living with HIV/AIDS (PWHA).

Method: PWHAs who had vitamin D (25-OH vitamin D, 25OHD) test results from 2012 to 2017 were enrolled.
