Background While anti-β2 glycoprotein 1 (anti-β2GP1) antibody positivity is included in the diagnostic criteria for antiphospholipid syndrome (APS), the association between anti-β2GP1 and the obstetrical complications of APS has been inconsistently reported and remains unclear. Objective We completed a case–control study nested within the Canadian Ottawa and Kingston (OaK) Birth Cohort to evaluate the association between anti-β2GP1 antibody positivity and placenta-mediated pregnancy complications. Study Design Five hundred cases were randomly selected among pregnant women who experienced any of the following independently adjudicated placenta-mediated pregnancy complications: preeclampsia, placental abruption, late pregnancy loss (≥ 12 weeks' gestation), and birth of a small-for-gestational age (SGA) infant < 10th percentile. Five hundred pregnant women without any placenta-mediated pregnancy complications were selected as controls. Stored blood samples were analyzed for the presence of anti-β2GP1 antibodies by enzyme-linked immunosorbent assay. Results Anti-β2GP1 immunoglobulin G (IgG) and/or immunoglobulin M (IgM) antibodies in titers ≥ 20 G/M units (> 99th percentile) were present in 24 of 497 (4.8%) of controls and 33 of 503 (6.6%) of cases. There was no significant difference between cases and controls for the composite outcome of any placenta-mediated pregnancy complications (odds ratio, 1.38, 95% confidence interval [CI], 0.8–2.37, p = 0.25). Conclusion Our results call into question the association between anti-β2GP1 antibodies and placenta-mediated pregnancy complications, with further research needed.

It is widely accepted that thrombophilia in pregnancy greatly increases the risk of venous thromboembolism. Pregnancy complications arise, at least partly, from placental insufficiency. Any change in the functioning of the gestational transient biological system, such as inherited or acquired thrombophilia, might lead to placental insufficiency. In this research we included 64 pregnant women with trombophilia and 70 cases non-trombophilic pregnant women, with or without PMPC, over a two-year period. The purpose of this multicenter case-control study is to analyze the maternal-fetal management options in obstetric thrombophilia, the impact of this pathology on the placental structure and possible correlations with placenta-mediated pregnancy complications. Maternal-fetal management in obstetric thrombophilia means preconceptional or early diagnosis, prevention of pregnancy morbidity, specific therapy as quickly as possible and fetal systematic surveilance to identify the possible occurrence of placenta-mediated pregnancy complications.

Introduction: Pre-eclampsia is a pregnancy specific disorder, characterised by the onset of hypertension and proteinuria. Pre-eclampsia is the leading cause of maternal, perinatal morbidity and mortality. The exact cause of pre-eclampsia is not known clearly and needs to be explored. Aim: To evaluate the maternal serum apelin 13 levels among pre-eclampsia and healthy pregnant women and also, to find the association between apelin 13 and blood pressure. Materials and Methods: A case-control study was conducted between Department of Biochemistry and Department of Obstetrics and Gynaecology, RL Jalappa Hospital and Research Centre, Kolar, Karnataka, India. After approval from the Institutional Ethics Committee and written informed consent from study subjects, a total of 270 pregnant women were recruited for this study. Among them, 135 pre-eclamptic women were considered as cases and 135 normotensive healthy pregnant women served as controls. According to the pre-eclampsia severity, cases were grouped into mild (n=47) and severe pre-eclampsia (n=88). Blood samples were collected from all the study subjects and was analysed for apelin 13 by Enzyme Linked Immunosorbent Assay (ELISA) method. Maternal and foetal adverse outcomes were recorded. Results were expressed as mean±Standard Deviation (SD). Categorical variables were expressed in percentages. Spearman’s correlation was applied and p<0.05 was considered significant. Results: The mean gestational age was 36.66±3.69 weeks which was, significantly low in pre-eclamptic women compared with healthy pregnant women. BMI (26.94±3.81 kg/m2), systolic (157.82±15.14 mmHg), diastolic (101.68±11.02 mmHg) and Mean Arterial Pressure (MAP) (120.20±11.12 mmHg), pulse rate (88.14±5.82 bpm), Aspartate Transaminase (AST) (25.25±12.49 IU/L) and Alanine Transaminase (ALT) (19.01±10.95 IU/L) were significantly increased in pre-eclamptic women when compared with control group. Mean maternal serum apelin 13 (341.44±218.63 pg/mL) concentrations were significantly lower in pre-eclampsia compared with healthy pregnant women. Maternal serum apelin 13 concentrations were negatively correlated with Systolic Blood Pressure (SBP) (r = -0.196), Diastolic Blood Pressure (DBP) (r = -0.172) and MAP (r =-0.204). Adverse maternal outcomes such as epigastric pain 75 (55.55%), oedema 62 (45.92%) and persistent headache 35 (25.92%) were higher in pre-eclamptic group. Additionally, adverse foetal outcomes were more in pre-eclamptic cases including significantly decreased birth weight (2.40±0.65), babies requiring Neonatal Intensive Care Unit (NICU) admission were 54 (40%), preterm birth (≤37 wks) in 50 (37.03%), Respiratory Distress Syndrome (RDS) 31 (22.96%), Small for Gestational Age (SGA) in 4 (2.96%) and Intra Uterine Death (IUD) in 11 (8.14%) babies. Conclusion: It was concluded from the present study that there was low maternal serum apelin 13 concentrations in pre-eclampsia and had negative correlation with blood pressure, suggesting its potential role in the pathophysiology of pre-eclampsia.

ABSTRACT Objective: The aim of this case–control study was to compare patients with a healthy peri-implant environment and patients affected by peri-implantitis, evaluating the occurrence of antibodies to extracellular matrix (ECM) molecules. The authors hypothesized the presence of ECM autoantibodies in serum of peri-implantitis patients. Materials and Methods: Patients were divided into two groups: one with dental implants with a diagnosis of peri-implantitis and one control group with implants classified as being “healthy.” Enzyme-linked immunosorbent assay was performed on patients' sera to detect human antibodies to type I, III, IV, and V collagens, laminin, and fibronectin. Fisher exact test was performed to evaluate statistical association, with a significant P < 0.05. Results: Forty-two patients were enrolled in this study, 27 females (64.28%) and 15 males (35.72%) with a mean age of 53 ± 29.69 years (age range 32–74). The presence of antibodies to CIII was recorded in 6/21 (28.57%) patients of test group, compared to just 2/21 (9.52%) for the control group, showing a statistically significant difference (P < 0.05). Other antibodies tested were found to be not statistically significant or absent. Conclusions: Within the limitations of this study, it can be concluded that further studies, with larger sample and different design, are necessary to address the research purpose, evaluating possible associations between anti-ECM antibodies and peri-implantitis.

Abstract Background: Whilst the impact of Covid-19 infection in pregnant women has been examined, there is a scarcity of data on pregnant women in the Middle East. Thus, the aim of this study was to examine the impact of Covid-19 infection on pregnant women in the United Arab Emirates population. Methods: A case-control study was carried out to compare the clinical course and outcome of pregnancy in 79 pregnant women with Covid-19 and 85 non-pregnant women with Covid-19 admitted to Latifa Hospital in Dubai between March and June 2020. Results: On admission, most pregnant women (69/79; 87%) were either asymptomatic or suffered mild respiratory symptoms, much like non-pregnant women. The main symptoms, observed in both groups, were fever, cough, headache, runny nose and myalgia. In early pregnancy four women had spontaneous miscarriages. However, severe Covid-19 illness, ICU admission, intubation and complications were observed in late pregnancy in 10/79 (13%) women with prior comorbidities. During the study period, 31/79 women delivered: 22 (70%) had a lower segment Caesarean section, 16 for obstetric reasons and 6 for severe Covid-19 pneumonia; and 12 had a preterm delivery. Postoperatively, none showed significant improvement on account of early delivery. Sepsis, acute renal failure and acute respiratory distress syndrome were the most common complications observed. The neonatal outcome was comparable to that of the general obstetric population, even though 12/31 (38%) were preterm and had to be admitted to the neonatal ICU. Two neonates, born by vaginal delivery, tested positive for Covid-19 after delivery. Both were asymptomatic and tests were negative within 72 hours. It was not possible to ascertain whether vertical transmission occurred in utero.Conclusions: Severe Covid-19 illness, ICU admission, intubation, complications and preterm deliveries were observed in late pregnancy in women with comorbidities. Pregnancy with Covid-19 infection, could, therefore, be categorised as high-risk pregnancy. It was not possible to confirm whether vertical transmission of Covid-19 had occurred during the third trimester of pregnancy.

Very limited information is available concerning the epidemiology ofT. gondiiinfection in pregnant women in eastern China. Therefore, a case-control study was conducted to estimate the seroprevalence of toxoplasmosis in this population group and to identify risk factors and possible routes of contamination. Serum samples were collected from 965 pregnant women and 965 age-matched nonpregnant control subjects in Qingdao and Weihai between October 2011 and July 2013. These were screened with enzyme linked immunoassays for the presence of anti-ToxoplasmaIgG and anti-ToxoplasmaIgM antibodies. 147 (15.2%) pregnant women and 167 (17.3%) control subjects were positive for anti-T. gondiiIgG antibodies, while 28 (2.9%) pregnant women and 37 (3.8%) controls were positive for anti-T. gondiiIgM antibodies (P=0.256). There was no significant difference between pregnant women and nonpregnant controls with regard to the seroprevalence of either anti-T. gondiiIgG or IgM antibodies. Multivariate analysis showed thatT. gondiiinfection was associated with location, cats in home, contact with cats and dogs, and exposure to soil. The results indicated that the seroprevalence ofT. gondiiinfection in pregnant women is high compared to most other regions of China and other East Asian countries with similar climatic conditions.

Background: Hepcidin, a peptide hormone composed of 25 amino acids. Hepcidin is synthesized mainly in the liver. Iron deficiency anemia (IDA) is common during pregnancy and is associated with higher maternal morbidity and mortality in Gaza strip. Understanding of hepcidin hormone and its role in iron metabolism could lead to a new sensitive indicator for earlier detection of cases with IDA. Objective: To assess hepcidin status among IDA pregnant women and its relationship with some biochemical variables in Gaza strip. Materials and methods: A case control study comprised 45 IDA pregnant women and 45 apparently healthy pregnant women. Questionnaire interviews were applied among the study population. Serum hepcidin and ferritin were measured by Enzyme-linked immunosorbent assay (ELISA), iron and total iron binding capacity (TIBC) were determined photometrically. Complete blood count (CBC) was also performed. Transferrin and transferrin saturation were calculated. An approval was obtained from Helsinki committee and ministry of health to conduct this study. Overall data were computer analyzed using SPSS (Ver. 18). Results: The mean levels of serum hepcidin, iron, transferrin saturation, and ferritin in cases were significantly lower compared to those of controls (2.6±4 ng/ml, 63.2±25.3 µg/dl, 15.6±8.0% and 8.0±9.7 ng/ml versus 7.5±7.3 ng/ml, 77.7±22.9 µg/dl, 23.5±8.0% and 15.4±14.3 ng/ml respectively with P=0.000). The Pearson correlation test showed that positive significant correlations between hepcidin levels and serum iron, ferritin, and transferrin saturation (P<0.001). On the other hand, negative significant correlations were showed with TIBC and transferrin (P<0.001). Conclusions: Serum hepcidin level has a relationship with anemia among pregnant women. Therefore, monitoring of hepcidin levels can play an important role in management of anemia among pregnant women.

BACKGROUND: Osteocalcin (OC) is the most common noncollagenous protein in bone matrix, which is synthesized only in bone tissue and by osteoblasts. The potential role of osteocalcin on glucose and fat metabolism has been previously reported. The aim of this study was to compare the serum OC level in pregnant women with and without gestational diabetes mellitus (GDM).METHODS: In the present case-control study, all pregnant women who were referred to a obstetrics and gynecology clinic in Sari, Iran, and met the inclusion criteria underwent an overall screening with a 75-g glucose tolerance test (GTT) at week 24 to 28 of gestation. The study was conducted between September 2018 and February 2019. Based on criteria, the pregnant women with confirmed GDM were matched with pregnant women without GDM in terms of baseline characteristics such as chronological age and BMI. The serum OC levels were also measured if vitamin D and calcium levels were normal. All data were analyzed using SPSS 21.RESULTS: The two groups with and without GDM had no significant difference in terms of age, BMI and OC level. There was no significant correlation between age and BMI with OC level in healthy pregnant women, respectively (P=0.49 and P=0.58). The correlation between BMI and age with OC level in GTT-positive pregnant women was 0.05 and -0.172, respectively, which was not significant (P=0.77 and P=0.36).CONCLUSION: According to the results of this study, there is no significant difference of serum OC levels in pregnant women with GDM compared to healthy pregnancy. Given that the levels of serum insulin or insulin resistance have not been assessed, these indices are recommended to be evaluated in future studies.

ObjectiveTo compare the ocular changes and Doppler velocimetric indices in preeclamptic and normotensive pregnant women.Methods and analysisThis was a case-control study of 71 preeclamptic women and 72 parity-matched normotensive pregnant women conducted at the University College Hospital, Ibadan, Nigeria. Demographic data were obtained using questionnaires. All participants had visual acuity assessment, funduscopy, intraocular pressure measurement and orbital Doppler ultrasonography. The differences in parameters between the two groups were tested using Student’s t-test for quantitative variables and χ2 tests for categorical variables.ResultsThere were no significant differences between cases and controls with respect to sociodemographic variables. The mean pulsatility index was 1.35±0.46 in cases and 2.1±0.4 in controls (p<0.001); the resistivity index was 0.7±0.18 in cases and 0.83±0.27 among the controls (p=0.01). A similar pattern was observed in the peak systolic velocity (p<0.001) and the peak ratio (p<0.001). There was no significant difference between the groups concerning end-diastolic velocity (p=0.535). Three preeclampsia patients (5.2%) had abnormalities on funduscopy compared with none of the controls. Preeclamptic women had significantly higher intraocular pressures in both eyes at baseline and at 24 hours post delivery.ConclusionThis study demonstrated lower Doppler velocimetry and impedance parameters and higher intraocular pressure among preeclampsia cases compared with controls. Abnormal funduscopic findings were observed in a few preeclamptic women and none among the controls. Ophthalmic artery Doppler parameters could be useful in identifying those women who are likely to suffer preeclampsia and its complications.

Preeclampsia is one of the most leading causes of maternal mortality in developing countries like Bangladesh. Several studies have demonstrated the relationship between platelets count and preeclampsia. The aim of the study was to assess the association of platelets count with preeclampsia. A case control study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka from July 2010 to June 2011. A total number of 100 pregnant women in third trimester of pregnancy attending in Obstetrics & Gynaecology Department of Dhaka Medical Hospital were selected as study subjects. Among them 50 diagnosed cases of preeclampsia were selected as cases and 50 normal healthy pregnant women as controls. Platelet count was measured in all study subjects. The mean platelet count in cases and controls were 1,44,260±96,472 and 1,98,100±51,219 respectively. The present study showed significant difference of mean platelet count between cases and controls. The study revealed that low platelets count is associated with preeclampsias. DOI: http://dx.doi.org/10.3329/jdnmch.v18i2.16018 J. Dhaka National Med. Coll. Hos. 2012; 18 (02): 24-26
