Declining maternal mortality in the face of persistently high HIV prevalence in a middle-income country.

OBJECTIVE: To estimate maternal mortality ratio (MMR) and determine maternal death causes and trends in Greater Soweto, Johannesburg, South Africa. DESIGN: Cross-sectional study. SETTING: Chris Hani Baragwanath Maternity Hospital (CHBMH) in Greater Soweto. POPULATION: Maternal deaths at CHBMH. METHODS: Record review of maternal deaths from 1997 to 2012, using hospital death records, with denominator data from the district health information system and the hospital. MAIN OUTCOME MEASURES: Maternal mortality ratio per 100,000 live births, and causes of death classified as in the South African confidential enquiries. RESULTS: There were 479 deaths, with a peak MMR of 139 in 2004 and a decline to 86 in 2012. Of 332 women tested, 245 (74%) were HIV-infected. Nonpregnancy-related infection (40%) was the most frequent cause of death, followed by hypertension (16%) and obstetric haemorrhage (13%). HIV infection rates in these groups were 92%, 30% and 61%, respectively. Previous caesarean section was associated with obstetric haemorrhage death (odds ratio [OR] 3.2, 95% confidence interval [95% CI] 1.7-6.0), maternal age ≥35 years with hypertension death (OR 2.2, 95% CI 1.2-3.7) and antenatal anaemia with nonpregnancy-related infection death (OR 4.0, 95% CI 2.3-6.9), compared with other causes of death. CONCLUSION: There is evidence of a decline in MMR since HIV treatment for pregnant women was introduced in 2004. Previous caesarean section, advanced maternal age, and anaemia were associated with death from obstetric haemorrhage, hypertensive disorders of pregnancy and nonpregnancy-related infections, respectively. MMR may be further reduced with accelerated initiation of HIV treatment during pregnancy.

Tuberculosis in pregnancy.

Tuberculosis (TB) remains an important infection in women globally. It is responsible for 700 000 deaths annually and is a major contributor to maternal mortality. Mycobacterium tuberculosis/HIV co-infection is common in areas of high HIV prevalence, and may be associated with significant perinatal and maternal morbidity. Improved diagnosis and treatment of TB in pregnant women are important interventions for both maternal and child health. Controlling TB in pregnancy in high-prevalence areas requires a range of interventions, including active TB screening in pregnant women, TB preventative therapy for HIV-infected pregnant women, treatment of active TB and linking mothers and children to TB care services.

Preventing mother-to-child transmission of HIV.

HIV transmission from mother-to-child remains a major cause of infant morbidity and mortality in resource-poor settings. There is consensus that women who need antiretroviral treatment should receive this during pregnancy and beyond, and that an appropriate antiretroviral prophylactic regimen should be given to those who do not yet need ongoing therapy. Infant feeding remains a major source of infection and new antiretroviral strategies, for mothers or children, are emerging with the potential to control this. Access to HIV testing and antiretroviral treatment or prophylaxis remain very limited in low resource settings and needs to be expanded.

The value and role of non-invasive prenatal testing in a select South African population.

BACKGROUND: Concerns have been raised about the injudicious use of non-invasive prenatal testing (NIPT) using cell-free DNA (cfDNA), which often leads to inaccuracies in interpretation of the role and value of cfDNA in prenatal screening. OBJECTIVES:  To determine the value and role of NIPT in a select South African (SA) population. METHODS:  A retrospective review of patients who elected to have NIPT between 1 October 2013 and 30 June 2015 at the Morningside Mediclinic Maternal and Fetal Medicine Centre in Johannesburg, SA. Patients had NIPT after either combined first-trimester screening (CFTS) or a second-trimester ultrasound scan. Data were collected on details of the first- and/or second-trimester screening, results of the NIPT, invasive tests done, decisions made in the event of abnormal results, and pregnancy outcomes. RESULTS:  Overall, 3 473 first- and second-trimester fetal assessments were done at the centre during the study period, and 2.3% of patients (n=82) elected to have NIPT. The majority of these individuals elected to have NIPT on the basis of positive findings on CFTS, or markers of aneuploidy detected on a second-trimester ultrasound scan. Of the tests done, 97.6% produced results. Of those with no results, one did not meet quality metrics and the other had a low fetal fraction of cfDNA. There were two abnormal NIPT results, one indicating a high risk of trisomy 13 and the other a triploidy. Patients who screened negative elected not to have an invasive test. CONCLUSION:  The value of NIPT in this study was that it made it possible to avoid a number of invasive tests. NIPT had a role in contingency screening.

Delayed presentation and diagnosis of metastatic hepatocellular carcinoma in pregnancy.

Hepatocellular carcinoma (HCC) is rare in women of reproductive age. If diagnosed, the underlying cirrhosis is associated with infertility in the majority of cases. There is limited literature on HCC in pregnancy, even more so for cases of metastatic disease. We present a case of delayed presentation and diagnosis of metastatic HCC in pregnancy. A 30-year-old pregnant woman presented at 23 weeks' gestation and was diagnosed as HIV-infected, with anaemia. She was initiated on an efavirenz-based fixed-dose combination and oral haematinics. She subsequently presented at 32 weeks' gestation with dyspnoea, and was diagnosed with pre-eclampsia. She was also found to have hepatosplenomegaly and ascites. She went into spontaneous preterm labour at 32 weeks and 4 days. A diagnosis of metastatic HCC was made postpartum, based on the radiological findings and biochemistry. We discuss the challenges of diagnosing metastatic HCC in pregnancy.
