A Multicenter Retrospective Cohort Study of the Profile of Seminal Fluid Analyses of Men Seeking Fertility Care at Different Hospitals.

BACKGROUND: Male infertility contributes 40 % of couple infertility. The prevalence of abnormal semen parameters has been on the increase. Age among other factors affects the fertility potential of males. This study analysed the pattern of seminal fluid parameters of males, seeking fertility treatment in hospitals and the relationship between age, volume and liquefaction time on these other semen parameters. METHODS: This is a multicentre retrospective cohort study conducted in eight secondary and tertiary hospitals in Nigeria. The case notes of couples that sort fertility care at the Gynaecology and Urology clinics of these hospitals from January 1st 2022 to December 31st 2022 were retrieved after receiving ethical approval. A purposeddesigned proforma based on the WHO manual for the examination of human semen was used for data collection. Outcome measures were time of semen collection and examination, volume of semen, sperm number, sperm concentration, PH, agglutination, liquefaction, motility,morphology, vitality, and white blood cell count. Data was analysed using SPSS version 23. Data were presented as means and proportions. P-value of < 0.05 was used as the level of significance. RESULTS: Overall, 1063 couples attended gynaecology and urology clinics with fertility-related concerns within the study period with a retrieval rate of 98.3%. The mean age of participants was 38.24 ± 8 years, while the mean semen volume and sperm concentrations were 2.62 ± 1.6 mls and 34.32 ± 7.4 million respectively. The age of participants significantly affected motility, volume and morphology (p-values of 0.001, 0.001 and 0.004 respectively). The total motility and sperm concentration have an inverse relationship with the age of the participants. CONCLUSION: This study shows that sperm motility decreases with the age of participants. It was also observed that the most common combined abnormality was oligoasthenozoospermia.

CONTEXTE: L'infertilité masculine représente 40 % de l'infertilité des couples. La prévalence des paramètres anormaux du sperme est en augmentation. L'âge, entre autres facteurs, affecte le potentiel de fertilité des hommes. Cette étude a analysé le profil des paramètres du liquide séminal des hommes cherchant un traitement de fertilité dans les hôpitaux et la relation entre l'âge, le volume et le temps de liquéfaction sur ces autres paramètres du sperme. MÉTHODES: Il s'agit d'une étude de cohorte rétrospective multicentrique menée dans huit hôpitaux secondaires et tertiaires au Nigeria. Les notes de cas des couples qui ont eu recours à des soins de fertilité dans les cliniques de gynécologie et d'urologie de ces hôpitaux entre le 1er janvier et le 31 décembre 2022 ont été récupérées après avoir reçu une approbation éthique. Un proforma conçu à dessein et basé sur le manuel de l'OMS pour l'examen du sperme humain a été utilisé pour la collecte des données. Les mesures des résultats étaient le temps de collecte et d'examen du sperme, le volume de sperme, le nombre de spermatozoïdes, la concentration en spermatozoïdes, le PH, l'agglutination, la liquéfaction, la motilité, la morphologie, la vitalité et la numération des globules blancs. Les données ont été analysées à l'aide de SPSS version 23. Les données ont été présentées sous forme de moyennes et de proportions. Une valeur P < 0,05 a été utilisée comme niveau de signification. RÉSULTATS: Dans l'ensemble, 1 063 couples ont fréquenté les cliniques de gynécologie et d'urologie pour des problèmes de fertilité au cours de la période d'étude, avec un taux de récupération de 98,3 %. L'âge moyen des participants était de 38,24 ± 8 ans, tandis que le volume moyen de sperme et les concentrations de spermatozoïdes étaient respectivement de 2,62 ± 1,6 ml et 34,32 ±7,4 millions. L'âge des participants a affecté de manière significative la motilité, le volume et la morphologie (valeurs p de 0,001, 0,001 et 0,004 respectivement). La motilité totale et la concentration en spermatozoïdes ont une relation inverse avec l'âge des participants. CONCLUSION: Cette étude montre que la mobilité des spermatozoïdes diminue avec l'âge des participants. Il a également été observé que l'anomalie combinée la plus fréquente était l'oligoasthénozoospermie. Mots-clés: Infertilité Masculine, Anomalies du Liquide séminal, Nigeria.

Seroprevalence of Hepatitis B, and C Viruses and HIV Infections among Antenatal Women in a Secondary Health Facility in Lagos, Nigeria.

BACKGROUND: Hepatitis B and C viruses and HIV infections contribute a significant proportion to maternal and perinatal morbidity and mortality in low and middle-income countries. While the burden of hepatitis B and C viruses is higher in low and middle-income countries, Nigeria also has the second largest burden of HIV. OBJECTIVES: To determine the seroprevalence of hepatitis B and C viruses and HIV infections among antenatal women who sought care at a secondary health facility in Lagos. METHODS: This was a retrospective review of patients managed in the antenatal clinic of 68 Nigerian Army Reference Hospital over one year. A study proforma was used to collect relevant data which were entered and analyzed using the IBM Statistical Package for Social Sciences (SPSS Statistics) Version 23. RESULTS: A total of 347 women attended prenatal care during the study period, however, only 329 cases with complete data were included in the final statistical analysis. The prevalence of HIV in our study was 6.4%, while HBV and HCV accounted for 6.2% and 1.8% respectively. Hepatitis B, and hepatitis C viruses and HIV Infections occurred in 3 (0.9%) of our patients, 6 (1.8%) of the women had HIV-HBV co-infection while 1 (0.3%) was infected with HIV-HCV. CONCLUSION: Our study re-emphasizes the public health importance of HBV, HCV and HIV screening in our antenatal clinics. This knowledge is very important for the implementation of effective prevention and control measures that will further decrease the mother-to-child transmission of these viruses.

CONTEXTE: Les virus de l'hépatite B et C et les infections par le VIH contribuent pour une part importante à la morbidité et à la mortalité maternelles et périnatales dans les pays à revenu faible et intermédiaire. Alors que le fardeau des virus de l'hépatite B et C est plus élevé dans les pays à revenu faible et moyen, le Nigeria a également le deuxième plus grand fardeau du VIH. OBJECTIFS: Déterminer la séroprévalence des virus de l'hépatite B et C et des infections par le VIH chez les femmes en période prénatale qui ont consulté dans un établissement de santé secondaire de Lagos. MÉTHODES: Il s'agit d'une étude rétrospective des patientes prises en charge dans la clinique prénatale de 68 références de l'armée nigériane sur une période d'un an. Un formulaire d'étude a été utilisé pour recueillir les données pertinentes qui ont été saisies et analysées à l'aide du progiciel statistique pour les sciences sociales IBM (SPSS Statistics) version 23. RÉSULTATS: Un total de 347 femmes ont suivi des soins prénataux pendant la période d'étude, cependant, seuls 329 cas avec des données complètes ont été inclus dans l'analyse statistique finale. La prévalence du VIH dans notre étude était de 6,4%, tandis que le VHB et le VHC représentaient respectivement 6,2% et 1,8%. Les virus de l'hépatite B et de l'hépatite C ainsi que le VIH étaient présents chez 3 (0,9%) de nos patientes, 6 (1,8%) des femmes avaient une co-infection VIHVHB tandis qu'une (0,3%) était infectée par le VIH-VHC. CONCLUSION: Notre étude souligne à nouveau l'importance pour la santé publique du dépistage du VHB, du VHC et du VIH dans nos cliniques prénatales. Ces connaissances sont très importantes pour la mise en œuvre de mesures de prévention et de contrôle efficaces qui permettront de diminuer davantage la transmission mère-enfant de ces virus.

Maternal Outcomes of Eclampsia at the Lagos University Teaching Hospital: A Six-Year Retrospective Review.

BACKGROUND: Eclampsia is one of the leading causes of maternal morbidity and mortality. OBJECTIVES: To determine the incidence as well as the maternal outcomes of eclampsia at the Lagos University Teaching Hospital (LUTH). METHODS: This was a retrospective review. RESULTS: During the six-year review period, 4182 women gave birth at our facility, out of which 67 cases of eclampsia were diagnosed (16 per 1000 deliveries). Four women died constituting a case fatality rate of 5.9%. Fifteen women were admitted to the intensive care unit, 6 women had acute kidney injury while 5 had abruptio placentae. Further comparison of our data with previous studies from our institution decades ago showed a continuous decrease in total number of eclamptic cases presenting to our facility (572 eclamptics in 1977 - 1986, 299 ECLAMPTICS IN 1986 - 1995, 165 IN 1996-2005 AND 67 IN 2015-2020). CONCLUSION: The case fatality rate from eclampsia is still high in our hospital. Increased utilisation of antenatal care may play an important role in improving the maternal outcomes from this life-threatening obstetric condition. There is need for maternal education and increase awareness on the importance of antenatal care and early referral to tertiary level of care in order to reverse this trend.

CONTEXTE: L'éclampsie est l'une des principales causes de morbidité et de mortalité maternelles. OBJECTIFS: Déterminer l'incidence ainsi que les issues maternelles de l'éclampsie à l'hôpital universitaire de Lagos (LUTH). METHODES: Il s'agissait d'une revue rétrospective. RESULTATS: Au cours de la période d'examen de six ans, 4182 femmes ont accouché dans notre établissement, dont 67 cas d'éclampsie ont été diagnostiqués (9,5 pour 1 000 accouchements). Quatre femmes sont décédées, soit un taux de létalité de 5,9 %. Quinze femmes ont été admises à l'unité de soins intensifs, 6 femmes avaient une lésion rénale aiguë tandis que 5 avaient un décollement placentaire. Une comparaison plus poussée de nos données avec des études antérieures de notre institution il y a des décennies a montré une diminution continue du nombre total de cas d'éclampsie se présentant à notre établissement (572 éclamptiques en 1977­1986, 299 éclamptiques en 1986-1995, 165 en 1996-2005 et 67 en 2015­2020). CONCLUSION: Le taux de létalité de l'éclampsie est encore élevé dans notre hôpital. L'utilisation accrue des soins prénatals peut jouer un rôle important dans l'amélioration des résultats maternels de cette affection obstétricale potentiellement mortelle. Il est nécessaire d'éduquer les mères et d'accroître la sensibilisation à l'importance des soins prénatals et de l'orientation précoce vers le niveau de soins tertiaires afin d'inverser cette tendance.

Epigenetic Modification in Methylene Tetrahydrofolate Reductase (MTHFR) Gene of Women with Pre-eclampsia.

BACKGROUND: Genetic and epigenetic factors play significant roles in the aetio-pathogenesis of pre-eclampsia (PE). The effects may vary across racial and geographical boundaries. The role of epigenetic modification in pre-eclampsia was studied among African populations in Lagos, Nigeria. AIM AND OBJECTIVES: This study aimed to determine the pattern of Methylene tetrahydrofolate reductase gene (MTHFR) CpG island methylation in pre-eclampsia, and evaluate associated covariates. METHODOLOGY: This study was an observational, cross-sectional, study conducted at the Lagos University Teaching Hospital and the Lagos State Island Maternity Hospital. A total of 400 pregnant women consisting of 200 pregnant women diagnosed with pre-eclampsia (study group) and 200 pregnant normotensive and apparently healthy women (control group) were recruited for the study. Demographic and clinical histories were obtained through questionnaires. The DNA Methylation status of the CpG Island in promoter region of the MTHFR gene was assessed using bisulphite conversion and methylation specific PCR method. The biochemical parameters measured in the study were: red cell folate, vitamin B12, plasma homocysteine (Hcy) and methylene tetrahydrofolate reductase enzyme level. RESULTS: Homozygous MTHFR CpG island hypomethylation pattern was significantly associated with pre-eclampsia (χ 2 = 22.96; p = 0.000), Mean values of plasma homocysteine in PE women with homozygous hypomethylation (26.1 ± 9.1 umol/L) were significantly higher than (20.1 ± 4.2 umol/L) observed in PE subjects with homozygous hypermethylation (p = 0.008). Homozygous CpG island hypomethylated pattern of the MTHFR promoter region, was associated with the lowest median MTHFR enzyme level (72.8 ± 39.8 pmol/L) compared with heterozygous methylated pattern (91.3 ± 60.9 pmol/L; p = 0.047) and homozygous methylated pattern (82.3 ± 31.0 pmol/L; 0.047). Red cell folate and Vitamin B12 levels were not significantly associated with CpG island methylation status. CONCLUSION: Epigenetic modification plays significant role in the pathogenesis of pre-eclampsia.

Methylene tetrahydrofolate reductase and methionine synthase gene polymorphisms as genetic determinants of pre-eclampsia.

BACKGROUND: Pre-eclampsia (PE) is a leading cause of maternal and neonatal mortality in Africa; and has been associated with the interplay of genetic, metabolic and environmental factors. Polymorphisms of methylene tetrahydrofolate reductase (MTHFR) and methionine synthase (MTR) folate cycle genes, have been controversially associated with pre-eclampsia in studies from different human populations. OBJECTIVES: To determine the distribution of MTHFR C677T and MTR A2756G polymorphisms in a Nigerian population and evaluate possible associations with the occurrence of pre-eclampsia and homocysteine metabolic derangement. MATERIALS AND METHODS: This study was a hospital based study carried out in Lagos, South-western Nigeria. Two hundred pregnant women clinically diagnosed with pre-eclampsia (study group) and 200 apparently healthy non-pre-eclamptic pregnant women (control group) were recruited for the study after written informed consent. Pre-eclampsia was diagnosed based on the International Society for the Study of Hypertension in Pregnancy re-classification of 2013. MTHFR C677T and MTR A2756G polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Statistical analyzes were performed using SPSS version 23. Hardy-Weinberg distribution were tested with χ2 test. Logistic regression model was used to evaluate the relationship of variables with pre-eclampsia. A value of p < 0.05 was considered statistically significant. RESULTS: MTHFR genotype frequencies of CC, CT and TT were 59.8%; 31.2% and 9.0% in study group and 76.6%; 22.3% and 1.0% in the control group respectively. MTR A2756G genotype frequencies of AA, AG and GG genotypes were 71.9%; 20.1% and 8.0% for the study group and 81.5%; 16.4% and 2.1% for the control group. Occurrence of pre-eclampsia was significantly associated with presence of T allele of MTHFR (OR = 1.855; p < 0.05) and G allele of MTR genes (OR = 1.269; p < 0.05), Homozygosity of TG haplotype significantly increased the occurrence of pre-eclampsia among Nigerian women (OR = 2.252; p < 0.05). Population attributable risk fraction percent for the T and G alleles were 16.4% and 11.5% respectively. Mean plasma Hcy level was not, however, significantly affected by MTHFR/MTR haplotypes (F = 1.54; p = 0.157). CONCLUSION: MTHFR C677T and MTR A2756G polymorphisms were associated with pre-eclampsia in a population of pregnant women in Lagos, Nigeria.

Methylenetetrahydrofolate Reductase Enzyme Level and Antioxidant Activity in Women with Gestational Hypertension and Pre-eclampsia in Lagos, Nigeria.

BACKGROUND: Deficiencies of enzymes in the folate cycle may lead to the generation of homocysteine, a toxic metabolic intermediate with pro-oxidant effect and ability to induce oxidant stress and lipid peroxidation as part of the pathophysiological process in gestational hypertension (GH) and pre-eclampsia (PE). AIM: The aim of this study is to assess the reliability of plasma homocysteine (hcy) 5, 10 methylenetetrahydrofolate reductase (MTHFR) enzyme and oxidative stress parameters as indicators of aetio-pathogenesis and severity of gestational hypertension and pre-eclampsia. SUBJECTS AND METHODS: This was a comparative cross-sectional study conducted over 6 months. Two hundred pregnant women were recruited from two sites. They were divided into gestation hypertension (n = 40), pre-eclampsia (n = 60) and control groups (n = 100). Parameters evaluated for statistical analysis were MTHFR enzyme level, plasma homocysteine and malondialdehyde (MDA) levels, with glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) activities. RESULTS: Mean plasma hcy level and MDA were significantly higher in pre-eclampsia and gestational hypertension when compared to control group (p < 0.05). However, MTHFR enzyme level, GSH, SOD and CAT were significantly higher in normotensive females when compared to PE and GH subgroups (p < 0.05). Pre-eclampsia was significantly associated with an increased risk of lipid peroxidation (OR = 4.923; p = 0.007). CONCLUSION: Pre-eclampsia and gestational hypertension are associated with marked homocysteine metabolic derangement and increased lipid peroxidation induced by oxidative stress and reduced MTHFR enzyme activity which may be the significant risk factors in the aetio-pathogenesis of GH and PE.

A prospective cohort study on the clinical utility of second trimester mean arterial blood pressure in the prediction of late-onset preeclampsia among Nigerian women.

BACKGROUND: Early detection of preeclampsia will help reduce the morbidities and mortalities associated with the disorder. Late-onset preeclampsia was the predominant presentation in this cohort. The search for biomarkers for predicting preeclampsia is still ongoing. Mean arterial blood pressure (MABP), which has the advantage of presenting a single cutoff value compared with the use of systolic and diastolic blood pressure measurements, merits evaluation. AIM: The study aims to evaluate the clinical utility of second trimester MABP in the prediction of preeclampsia. METHODS: This was a prospective cohort study of 155 normotensive, nonproteinuric pregnant women without prior history of gestational hypertension. The women were booked patients attending the antenatal clinic at the Lagos University Teaching Hospital and were all in their second trimesters of pregnancy. The outcome measures were systolic blood pressure, diastolic blood pressure, and MABP. The end point of the study was the development of preeclampsia. The diagnosis of preeclampsia was made by the attending obstetrician. The data were analyzed using the IBM SPSS statistical software. Statistical significance was set at P < 0.05. RESULTS: One hundred and fifty-five pregnant women participated in the study. Eleven (7.1%) of the women developed preeclampsia after 34 weeks gestation and 144 (92.9%) had normal pregnancy. The mean gestational age at the time of assessment was 18.88 ± 3.15 weeks with a range of 14 weeks to 27 completed weeks. There was a statistically significant increase in the systolic blood pressure, diastolic blood pressure, and MABP values in the group of women who later developed preeclampsia, P = 0.005, 0.001, and <0.001, respectively. At a false-positive rate of 10%, MABP value of 88.33 mmHg predicted preeclampsia with a specificity of 90% and a sensitivity of 45.5%, P <0.05. The area under the receiver-operative characteristics curve (AUC) was 0.732 (95% confidence interval, 0.544-0.919, P = 0.011). The negative predictive value (NPV) was 88.88% and the positive predictive value (PPV) was 45.45%, P < 0.05. At an MABP cutoff of 88.33 mmHg, preeclampsia was predicted with a relative risk of 4.44 and a positive likelihood ratio of 6.46, P < 0.05. CONCLUSIONS: With an AUC of 0.732, MABP performed moderately (considering that excellent performance has an AUC of 1.0) in the prediction of late-onset preeclampsia in Nigerian women. Its high NPV suggests a strong ability to rule out preeclampsia and help to appropriate management.

Early pregnancy plasminogen activator inhibitor-1 levels in Nigerian women and its relationship with preeclampsia.

AIM: This study compared early plasma levels of plasminogen activator inhibitor-1 (PAI-1) in normal pregnancy and preeclampsia and determined its relationship with disease severity. SUBJECTS AND METHODS: This was a prospective cohort study of 195 normotensive, aproteinuric pregnant women without prior history of gestational hypertension. The women were attending the Antenatal Clinic at The Lagos University Teaching Hospital and were within 24 weeks gestation at recruitment. The outcome measures were PAI-1, systolic blood pressure (SBP), diastolic blood pressure (DBP), and significant proteinuria. The endpoint of the study was the development of preeclampsia. The diagnosis of preeclampsia was made by the attending Obstetrician. The data were analyzed using the IBM SPSS statistical software. Statistical significance was set at P < 0.05. RESULTS: First trimester PAI-1 levels were significantly higher in the women who later developed preeclampsia compared to those who had a normal pregnancy (P < 0.0001). In these group of women who later developed preeclampsia, PAI-1 had an inverse relationship with gestational age (r = 0.878) whereas in normal pregnancy, PAI-1 and gestational age had a direct relationship (r = 0.017). Second trimester systolic and DBP values were also significantly higher in the women who later developed preeclampsia compared to normal pregnancy, P = 0.007 and 0.004, respectively. There was, however, no correlation between PAI-1 values and SBP, DBP and proteinuria in the women who developed preeclampsia. CONCLUSION: Plasma levels of PAI-1 are increased early in pregnancies complicated by preeclampsia, but the lack of correlation of this marker with disease severity may limit its clinical utility.

Plasma D-dimer reference ranges in pregnant Nigerians.

BACKGROUND: The use of D-dimer as a screening test for thromboembolic disorders has not been validated in pregnancy thus necessitating further studies. This cross sectional study was carried out among Pregnant Nigerians at the Nigerian Air Force Hospital Antenatal Clinic, Ikeja, Lagos. OBJECTIVE: This study was to determine local reference ranges for plasma D-dimer in both pregnant and non-pregnant females and compare differences in both populations. METHODS: Structured questionnaires were administered on a total of 365 participants which included 71 apparently healthy non-pregnant females, 64 women in the first trimester of pregnancy (≤13 weeks gestation); 65 women at the second trimester of pregnancy (14-26 weeks), and 82 pregnant females at the third trimester of pregnancy (> = 27 weeks). Citrated blood was collected for estimation of prothrombin time (PT), activated partial thromboplastin time (aPTT), and D-dimer estimation by ELISA method. Aspartate aminotransferase (AST) and alanine aminotransferase enzymes (ALT) were estimated using the Hitachi chemistry analyzer. Reference ranges were estimated non-parametrically using the Reference Value Advisor V 2.1. RESULTS: Median D-dimer level for non-pregnant females was 190 ng/mL, while the median D-dimer levels for pregnant female in 1st, 2nd, and 3rd trimester were 485 ng/ml; 620 ng/mL; and 1185 ng/mL respectively.Reference ranges were calculated to be 86-494 ng/mL; 338-624 ng/mL; 451-799 ng/mL and 665-1262 ng/mL for non-pregnant females, 1st, 2nd, and 3rd trimester of pregnancy respectively. CONCLUSION: A diagnostic algorithm for venous thromboembolism (VTE) in pregnant women which combines clinical suspicion with elevated plasma D-dimers levels above estimated reference range for each trimester should precede definitive formal imaging.
