Maternal Profiles and Pregnancy Outcomes: A Descriptive Cross-Sectional Study from Angola.

OBJECTIVES: To characterize pregnant women admitted to Irene Neto Maternity Hospital, Lubango city, Huíla province, and their pregnancy outcomes. METHODS: We conducted a descriptive cross-sectional facility-based survey between October 2016 and September 2017, involving 500 pregnant women, followed from admission in labor until the end of delivery. Mean (SD) was computed for quantitative variables, while relative and absolute frequencies were determined for categorical variables. Additionally, confidence intervals were estimated. RESULTS: Among pregnant women 18.3% were adolescents (≤ 19 years) and 14.5% had advanced maternal age (≥ 35 years). Illiteracy was reported by 8.2%. One in three (33.6%) had a short stature (< 1.55 m). Malaria was the most frequent infection during pregnancy (16.3%). Upon admission, 18.1% were anemic (Hb < 11 g/dl) and 36.0% had hypertension (SBP ≥ 140 mmHg and/or DBP ≥ 90 mmHg), contrasting with the few cases reported of chronic hypertension and pregnancy-induced hypertension. There were 15 twin pregnancies. Cesarean section was performed in 25.2% of the women, although there was no medical indication for 23.0% of women having cesareans. Two maternal deaths occurred in our sample. Among live births from singleton pregnancies (97.1%), birth asphyxia (Apgar < 7 at 5 min) was observed in 22.7% and 10.3% had low birth weight (< 2.5 kg). CONCLUSIONS: There are very few studies reporting pregnancy outcomes in Angola. This analysis presents data from Huíla province, the second most populous province. We identified characteristics for higher risk of adverse pregnancy outcomes: adolescence, illiteracy, and short stature. Among newborn outcomes, birth asphyxia and low birth weight demand special attention. Further research is needed to explore the non-medical indications for cesarean section and to better understand the twinning rate in Lubango.

Seropositivity rate and sociodemographic factors associated to HIV, HBV, HCV and syphilis among parturients from Irene Neto Maternity of Lubango city, Angola.

OBJECTIVES: To characterise infections by HIV, Treponema pallidum, hepatitis B (HBV) and C virus (HCV) in parturients admitted to Irene Neto Maternity, Lubango city, Huíla province, Angola, namely its seropositivity rate and its association with sociodemographic factors. METHODS: An observational, cross-sectional and analytical facility-based survey was conducted among 500 parturients at Irene Neto Maternity, from October 2016 to September 2017. Women in labour were screened for antibodies against HIV-1/2, T. pallidum and HCV. Antigen detection was used to diagnose HBV infections. Sociodemographic data were also collected. The seropositivity rate and respective CIs were estimated at a level of 95%. Multivariable logistic regression models were performed to explore the association between the studied infections and sociodemographic factors. RESULTS: In 11.8% of the parturients (95% CI 9.3 to 14.9), at least one infection was detected. HBV infection was the most common (8.6%), followed by HIV infection (3.0%) and syphilis (1.0%). Coinfection with HBV and HIV was observed in two parturients (0.4%) and HBV, HIV and T. pallidum were all detected in one parturient (0.2%). No HCV infection was detected. For each additional year of formal education, pregnant women had a 10.0% lower chance of being infected with HBV (adjusted OR=0.900, 95% CI 0.816 to 0.992). CONCLUSIONS: This study is one of the few reports contributing for the knowledge of some sexually transmitted infections epidemiology in Angola. The seropositivity rate of the studied infections is of concern, especially the high endemicity of HBV. There is a need for a stronger commitment and further research to design cost-effective public health and clinical interventions to improve the situation.

Sepsis, meningitis and cerebral abscesses caused by Citrobacter koseri.

After a 36-week diamniotic dichorionic gestation, an infant was delivered by elective caesarean section due to growth restriction and altered diastolic flow in the umbilical artery. Birth weight was 2140 g. The patient was admitted for exclusive parenteral nutrition, with umbilical venous catheter placement. Sinus tachycardia and temperature instability with positive inflammatory markers occurred at 51 h. Penicillin and gentamicin were started, but 6 h later septic shock with disseminated intravascular coagulation was noted. Vancomycin and meropenem were started and penicillin suspended. Citrobacter koseri was isolated from blood culture. Generalised clonic convulsions occurred on day 4, and an electroencephalogram revealed severe encephalic dysfunction. Cerebrospinal fluid cytochemical analysis was suggestive of meningitis, although culture was negative. Cefotaxime was added to the drug regimen. Cranioencephalic MR showed a temporal abscess and diffuse hemispheric destruction, with no indications for neurosurgery. After 6 weeks of therapy, neuroimaging follow-up showed multiloculated cystic encephalomalacia. Currently, the patient is 14 months old with axial hypotonia and decreased movements. The source of infection has not been determined. Nosocomial infection cannot be excluded and vertical transmission is unlikely.
