Background There are few published data on the role of vitamin D concentrations during pregnancy in sub-Saharan Africa. Thus, the aim of the current study was to investigate the association between 25-hydroxyvitamin D (25[OH)]D) levels and pre-eclampsia. Method A case-control study, with 60 women in each arm, was conducted in Medani Hospital in Sudan. The cases were women with pre-eclampsia and healthy pregnant women as controls. The medical and obstetric history was obtained using a questionnaire. The serum 25(OH)D concentrations were measured using ELISA. Results The median (IQR) of 25(OH)D concentration was significantly lower in women with pre-eclampsia than in the controls (10.0 [6.5] vs 18.3 [22.1] ng/mL). Fifty-three cases with pre-eclampsia (88%) and 36 cases in the control group (60%) had vitamin D deficiency (25(OH)D level≤20 ng/mL). Multivariate logistic regression showed that the 25(OH)D levels were negatively associated with pre-eclampsia (adjusted OR [AOR]=0.87, 95% CI 0.81 to 0.92). Vitamin D-deficient women were at a higher risk of pre-eclampsia (AOR=4.51, 95% CI 1.70 to 11.94). Conclusion Low 25(OH)D levels were reported in women with pre-eclampsia and were an independent risk factor for pre-eclampsia. [ABSTRACT FROM AUTHOR]

Background Anaemia during pregnancy is associated with adverse maternal and child health. Investigations of anaemia and its predictors among pregnant women are needed for preventive measures. Methods A cross-sectional study was conducted to investigate the prevalence and determinants of anaemia in early pregnancy in Khartoum, Sudan. Clinical characteristics were gathered using a questionnaire. Serum ferritin, magnesium and high-sensitivity C-reactive protein (hs-CRP) were measured using different laboratory methods. Results Of the 180 women in the study, 65.0% had anaemia (haemoglobin [Hb] <11 g/dl), 0.6% had severe anaemia (Hb <7 g/dl), 38.9% had iron deficiency (serum ferritin <15 μg/l), 30.6% had iron deficiency anaemia (<11 g/dl and serum ferritin <15 μg/l) and 57.2% had magnesium deficiency (<1.80 mg/dl). There was no significant difference in the age, parity, gestational age, body mass index (BMI) and hs-CRP between anaemic and non-anaemic pregnant women. Anaemic pregnant women had significantly lower levels of serum ferritin and serum magnesium. While age, parity, gestational age, BMI and hs-CRP were not associated with anaemia, low serum ferritin (odds ratio [OR] 0.97 [95% confidence interval {CI} 0.96 to 0.99]) and low serum magnesium (OR 0.91 [95% CI 0.84 to 0.99]) were associated with anaemia. There were significant positive correlations between Hb and serum ferritin (r=0.382, p<0.001) and serum magnesium (r=0.192, p=0.010). Conclusion The role of magnesium as a possible contributing factor to anaemia in pregnancy has important implications for prevention and treatment of these women. [ABSTRACT FROM AUTHOR]

Background: Previous published studies have reported conflicting results of association between hepatitis B virus (HBV) infection and preeclampsia. There was no published data on HBV and preeclampsia in Africa including Sudan. The aim of the present study was to investigate the association between HBsAg seropositivity and preeclampsia. Methods: A case -controls study (200 women in each arm) was conducted at Saad Abualila Maternity Hospital, Khartoum, Sudan. The cases were women with preeclampsia and the controls were healthy pregnant women. Socio-demographic characteristics were gathered using questionnaire and HBsAg was investigated using an ELISA. Results: There was no significant difference between the cases and the controls in their age, parity, residence, education and blood groups. The majority of the cases were mild preeclampsia (159; 79.5%). In comparison with the controls, a significantly higher number of the cases were HBsAg seropositive [30 (15.0%) vs. 12 (6.0%), P = 0.005]. In binary regression women with HBsAg seropositive were at higher risk of preeclampsia than women who were HBsAg seronegative (OR = 2.86, 95%, CI = 1.41-5.79, P = 0.003). Conclusion: In the current study HBsAg seropositivity is associated with preeclampsia. Preventive measure should be implemented. [ABSTRACT FROM AUTHOR]

There are few published studies on the association between vitamin D concentrations and preterm birth (PB) in sub-Saharan Africa. The current study aimed to assess the association between 25-hydroxyvitamin D (25[OH)] D) levels and PB. A matched case–control study (60 women in each arm) was conducted in Medani maternity hospital in central Sudan. The cases were women with spontaneous PB, and healthy women with term deliveries were the controls. The clinical/medical and obstetric history was gathered using a questionnaire. The enzyme-linked immunosorbent assay was used to measure the serum 25(OH)D levels. Women with PB had significantly lower median (interquartile range) 25(OH)D concentrations compared with the controls (18.4 (7.3) ng/mL vs. 20.2 (16.5) ng/mL, p = 0.001). Forty-two (70.0%) women with PB and 29 (48.3%) women in the control group had vitamin D deficiency (25(OH)D level ≤ 20 ng/mL). The results of the multivariable logistic regression showed that the 25(OH)D concentrations were negatively associated with PB (adjusted odds ratio (aOR) = 0.92, 95% confidence interval (CI) = 0.87–0.97). Vitamin D-deficient pregnant women were at a higher risk of PB (aOR = 2.69, 95% CI = 1.17–6.23). Low 25(OH)D concentrations were found at the time the variable was determined in women with spontaneous PB and were an independent risk factor for PB. [ABSTRACT FROM AUTHOR]

Objectives: The aim was to investigate the prevalence of and factors associated with periodontal disease among pregnant Sudanese women. A cross-sectional study was conducted at the Antenatal Care Clinic of Saad Abualila Hospital (Khartoum, Sudan) from August to October 2018. Socioeconomic-demographic information and reproductive history were gathered using a questionnaire. Body mass index was computed from the weight and height. The diagnosis of periodontal disease was performed using criterion that also evaluated bleeding upon probing. Results: Four hundred and four women were enrolled in the study, with a mean (SD) gestational age of 30.0 (8.7) weeks. Their mean (SD) age and parity were 27.0 (5.7) years and 1.6 (1.7), respectively. Ninety-seven (24.0%) of these 404 women had periodontal disease, which was mild, moderate and severe in 49 (12.1%), 36 (8.9%) and 12 (3.0%) women respectively, while 307 (76.0%) women had no periodontal disease. In logistic regression, age, parity, education, and brushing were not associated with periodontitis, but lower gestational age was associated with periodontal disease (OR = 0.96, 95% CI 0.94–0.99, P = 0.011).
