Pregnancy Rates and Outcomes of HIV-Infected Women in Korea

Pregnancy incidence, outcomes and associated factors in a cohort of women living with HIV/AIDS in Rio de Janeiro, Brazil, 1996-2016

The aim of this research was to analyze pregnancy incidence and associated factors in a cohort of 753 women living with HIV/AIDS (WLWHA) in Rio de Janeiro, Brazil, from 1996 to 2016. Women aged 18-49 years who were not on menopause (surgical or natural) and did not have a tubal ligation were eligible for the study. Data were collected by medical professionals during initial and follow-up visits. Person-time pregnancy incidence rates were calculated throughout the follow-up period. Pregnancy incidence-associated factors were investigated by univariate and multiple analyzes, using an extension of the Cox survival model. Follow-up visits recorded 194 pregnancies, with an incidence rate of 4.01/100 person-years (95% CI: 3.47; 4.60). A higher pregnancy incidence was associated with CD4 nadir ≥ 350 cells/mm³, use of an antiretroviral regimen not containing Efavirenz, and prior teenage pregnancy. In turn, women with a viral load ≥ 50 copies/mL, age ≥ 35 years old, with two or more children and using a highly effective contraceptive method showed a lower incidence. Results showed a significant reduction in pregnancy incidence after 2006, a significant reduction in female sterilization from 1996 to 2016, and a high rate of cesarean sections. The association found between pregnancy incidence and the use of contraceptive methods and virological control markers suggests a good integration between HIV/AIDS and reproductive health services. The high rate of cesarean section delivery indicates the need to improve childbirth care.

Effect of predictors on incidence rate of pregnancy among reproductive age women on antiretroviral therapy at public hospitals of Jigjiga and Harar Towns, Eastern Ethiopia: a retrospective cohort study

BACKGROUND

Globally, Human Immunodeficiency Virus (HIV) is the leading cause of death in women of reproductive age and accountable for a quarter of deaths during pregnancy in sub-Saharan Africa including Ethiopia. Introduction of antiretroviral therapy to women living with HIV highly improves lifestyle and the desire to have children. A comprehensive understanding of baseline predictors of pregnancy among women receiving ART essential to reduces unintended pregnancies, appropriate care, and preventing transmission from mother to child.

OBJECTIVE

To determine the effect of baseline predictors on incidence rate of pregnancy among reproductive age women on antiretroviral therapy at public hospitals of Jigjiga and Harar town, Eastern Ethiopia from February 15 to march 15, 2020.

METHODS

Retrospective cohort study was conducted on randomly selected 420 HIV-infected women using data recorded from September 11, 2014, to September 10, 2019 in Jigjiga and Harar town in Eastern Ethiopia. Simple random sampling was used to select study subjects from each hospital. Data were entered to Epi data version 3.2 and exported to Stata version 14.2 for analysis. Kaplan-Meier failure, and Cox proportional hazards model were used to estimate the incidence, and to identify predictors of pregnancy respectively. Variables which were significant (P value < 0.05) in the multivariate analysis were considered independent predictors of pregnancy.

RESULTS

The overall incidence rate of pregnancy was 9.1 per 100 person-years (95% CI 7.19, 11.76). Being unadvanced HIV disease stage (AHR: 2.50; 95% CI 1.46, 4.19), having less than two children (AHR: 2.93; 95% CI 1.59, 5.40), and disclosed HIV status (AHR: 2.25; 95% CI 1.34, 3.79) were independent predictors of pregnancy.

CONCLUSION

The incidence rate of pregnancy among reproductive age women on ART was found to be considerable. Being unadvanced HIV disease stage, having less than two children, and disclosed HIV status were independent predictors of pregnancy. Thus, tailoring counseling have to be designed to enhance better pregnancy planning and consecutive health outcomes.

A hybrid of long short-term memory neural network and autoregressive integrated moving average model in forecasting HIV incidence and morality of post-neonatal population in East Asia: global burden of diseases 2000-2019

Background

To forecast the human immunodeficiency virus (HIV) incidence and mortality of post-neonatal population in East Asia including North Korea, South Korea, Mongolia, Japan and China Mainland and Taiwan province.

Methods

The data on the incidence and mortality of HIV in post-neonatal population from East Asia were obtained from the Global Burden of Diseases (GBD). The morbidity and mortality of post-neonatal HIV population from GBD 2000 to GBD 2013 were applied as the training set and the morbidity and mortality from GBD 2014 to GBD 2019 were used as the testing set. The hybrid of ARIMA and LSTM model was used to construct the model for assessing the morbidity and mortality in the countries and territories of East Asia, and predicting the morbidity and mortality in the next 5 years.

Results

In North Korea, the incidence and mortality of HIV showed a rapid increase during 2000–2010 and a gradual decrease during 2010–2019. The incidence of HIV was predicted to be increased and the mortality was decreased. In South Korea, the incidence was increased during 2000–2010 and decreased during 2010–2019, while the mortality showed fluctuant trend. As predicted, the incidence of HIV in South Korea might be increased and the mortality might be decreased during 2020–2025. In Mongolia, the incidence and mortality were slowly decreased during 2000–2005, increased during 2005–2015, and rapidly decreased till 2019. The predicted incidence and mortality of HIV showed a decreased trend. As for Japan, the incidence of HIV was rapidly increased till 2010 and then decreased till 2015. The predicted incidence of HIV in Japan was gradually increased. The mortality of HIV in Japan was fluctuant during 2000–2019 and was slowly decreased as predicted. The incidence and mortality of HIV in Taiwan during 2000–2019 was increased on the whole. The predicted incidence of HIV during was stationary and the mortality was decreased. In terms of China Mainland, the incidence and mortality of HIV was fluctuant during 2000–2019. The predicted incidence of HIV in China Mainland was stationary while the mortality was rapidly decreased.

Conclusion

On the whole, the incidence of HIV combined with other diseases in post-neonatal population was increased before 2010 and then decreased during 2010–2019 while the mortality of those patients was decreased in East Asia.

Adverse pregnancy outcomes among pregnant women living with HIV in Hubei province, China: prevalence and risk factors

Mother-to-child transmission of Human Immunodeficiency Virus (HIV) has been greatly reduced with the advance of intervention technology. However, adverse pregnancy outcomes (APOs) are still common, and little is known about the driving forces of APOs among pregnant women living with HIV in China. Between January 2004 and December 2020, a total of 638 pregnancies among pregnant women living with HIV were enrolled in this study, 84 (13.2%) pregnancies with 87 APOs were reported. Preterm birth (3.8%), ectopic pregnancy (3.4%), spontaneous abortion (2.0%), and embryo arrest (1.7%) were the most common APOs in pregnant women living with HIV. Exposure to antiretroviral drugs (ARVs) during the first trimester (RR =  4.077, 95% CI: 0.521, 1.484, P<0.001) and the first CD4+ T lymphocyte count (CD4 count)≤ 350/μl (RR =  2.227, 95% CI: 0.063, 0.991, P = 0.026) were risk factors of APOs. The age≤ 30 years (RR =  -2.513, 95% CI: -1.067, -0.132, P = 0.012) was associated with the decreasing of APOs. Encouraging people to initiate combination antiretroviral therapy and reach a high CD4 count level before pregnancy would be helpful to prevent APOs. Pregnant women exposed to ARVs in the first trimester needed more attention for APOs.

Changing Trends in Pregnancy and Childbirth among Women Living with Human Immunodeficiency Virus at a Tertiary Hospital in Korea: A 28-Year Experience

BACKGROUND

The reports about fertility desire and pregnancy outcome among women infected with human immunodeficiency virus (HIV) in Korea are scarce. This study aimed to determine the changing trend in pregnancy incidence among women infected with HIV in Korea.

MATERIALS AND METHODS

We retrospectively reviewed the medical records of women infected with HIV visiting Pusan National University Hospital between January 1990 and October 2018.

RESULTS

A total of 149 women with HIV infection visited the study hospital. Among them, 33 pregnancies in 24 (16.1%) women were identified. There were 17 live births (51.5%) and 13 abortions (39.4%), whereas 3 women (9.1%) were transferred to another hospital or were lost to follow-up. The number of live birth rose from 0 in 1990-1998 to 17 in 1999-2018. The proportion of repeated pregnancies after HIV diagnosis also increased steeply, from 14.3% in 1999-2008 to 50% in 2009-2018. However, the number of abortions also increased over time. There were 8 induced abortions, 7 (87.5%) of them were diagnosed with HIV infection during pregnancy and 3 (37.5%) were unplanned pregnancies. Eighteen babies, including 1 twin case, were born from 17 births. There was no mother-to-child HIV transmission in our study.

CONCLUSION

The number of pregnancies among women with HIV infection and repeated pregnancies after HIV diagnosis has been increasing in Korea, probably due to the desire of HIV patients to have more children. However, the number of abortions also increased, probably due to health concerns and uncertain pregnancy outcome.
