RESUMO
Pregnancy in kidney and liver transplant recipients presents unique challenges and risks for both maternal and fetal health. This article examines the management of pregnancy in kidney and liver transplant recipients, focusing on pre-pregnancy counselling, trimester-specific care, the teratogenic effects of immunosuppressive drugs, and the role of the multidisciplinary team. While South African (SA) data on this topic are limited, the Transplant Pregnancy Registry International has provided valuable insights. Despite the increased risk of maternal and fetal complications, the overall risk of graft loss during pregnancy is low. Graft survival rates are comparable between pregnant and non- pregnant transplant recipients, except for pregnancies occurring within 1 year of transplantation. By addressing the complexities of managing pregnant women with kidney or liver transplants, this article underscores the importance of tailored care and the involvement of various medical specialists. It also explores the safety of and potential complications associated with specific immunosuppressive therapies during pregnancy. Further research is needed to enhance our understanding and optimise the management of these high-risk pregnancies in SA.

BACKGROUND: The efficacy and safety of thromboprophylaxis in pregnancy at intermediate to high risk of venous thrombo-embolism (VTE) is an area of ongoing research. AIM: This study aimed to assess thrombosis and bleeding outcomes associated with thromboprophylaxis in women at risk of VTE. METHODS: A cohort of 129 pregnancies, who received thromboprophylaxis for the prevention of VTE, were identified from a specialist obstetric clinic in Johannesburg, South Africa. Intermediate-risk pregnancies, with medical comorbidities or multiple low risks, were managed with fixed low-dose enoxaparin antepartum and for a median (interquartile range) of 4 (4) weeks postpartum. High-risk pregnancies, with a history of previous VTE, were managed with anti-Xa adjusted enoxaparin antepartum and for a median of 6 (0) weeks postpartum. Pregnancy-related VTE was objectively confirmed. Major bleeding, clinically relevant nonmajor bleeding (CRNMB) and minor bleeding were defined according to the International Society on Thrombosis and Hemostasis Scientific Subcommittee. RESULTS: Venous thrombo-embolism occurred antepartum in 1.4% (95% CI: 0.04-7.7) of intermediate and 3.4% (95% CI: 0.4-11.7) of high-risk pregnancies. Bleeding events occurred in 7.1% (95% CI: 2.4-15.9) of intermediate and 8.5% (95% CI: 2.8-18.7) of high-risk pregnancies. Of these bleeding events, 3.1% (95% CI: 1.0-8.0) were classified as major bleeding. On univariate analysis, no independent predictors of bleeding were identified. CONCLUSION: The rates of thrombosis and bleeding in this predominantly African population were consistent with similar studies and can be used to inform pregnant women of the benefits of anticoagulation and the risks of potential bleeding.

BACKGROUND: The majority of maternal deaths in South Africa (SA) occur as a result of non-pregnancy-related infections (NPRI). Pregnancy is a known risk factor in severe COVID19, increasing the burden of NPRI in SA. In this study, we describe the prevalence, profile and clinical outcomes of pregnant women with COVID19 admitted to a tertiary facility. OBJECTIVES: To describe the prevalence, profile and clinical outcomes of pregnant women with COVID19 admitted to a tertiary facility in Gauteng, SA. METHODS: We performed a retrospective review of all pregnant women with COVID19 admitted to Charlotte Maxeke Johannesburg Academic Hospital between 6 March and 30 August 2020. Data collected included demographics, medical history, obstetric history, clinical findings and laboratory variables. Outcomes assessed were mortality, admission to intensive care unit (ICU), symptomatic v. asymptomatic disease, maternal and fetal outcome and mode of delivery. RESULTS: A total of 204 pregnant women were included in the study. Of these, 33 (16.2%) women were critically ill, with 21 (10.3%) admitted to the ICU and 3 (1.5%) deaths related to COVID19. The median gestational age was 37 weeks and median birthweight 2 940 g. Sixty-seven women (33%) were HIV-positive, in keeping with national statistics regarding HIV in pregnancy. Caesarean section was the most common mode of delivery (n=105, 60%). However, no women underwent caesarean section for indications related to COVID19. CONCLUSION: COVID19-related mortality in our cohort was higher than that seen internationally, likely due to differences in background maternal mortality rates and difficulty in accessing care.

Pregnant women are at greater risk of severe COVID-19 than non-pregnant women. Despite limited safety data on use of COVID-19 vaccines in pregnancy, many international societies have recommended their use when pregnant women are at particularly high risk of acquiring COVID-19, or have suggested that vaccines should not be withheld from pregnant women where no other contraindications to COVID-19 vaccination exist. A number of vaccines, including those against influenza, tetanus and pertussis, have been shown to reduce both maternal and infant morbidity and mortality when used antenatally. We explore the role of COVID-19 vaccination in the setting of pregnancy, discuss the limited data available, and summarise current international guidelines.
