Study of Abnormal Liver Function Test during Pregnancy in a Tertiary Care Hospital in Chhattisgarh

Comparing Feto-Maternal Outcomes in Pregnant Women With Normal and Abnormal Liver Function Tests: A Prospective Observational Study

INTRODUCTION

Pregnant women with abnormal liver function tests (LFTs) require proper evaluation and timely management to reduce maternal and fetal morbidity and mortality.

OBJECTIVE

The present study was done with the objective of determining feto-maternal outcomes in antenatal women with abnormal LFTs and comparing them with antenatal women having normal liver function. The prevalence and possible causes of derangements in LFT were also identified.

METHOD

Pregnant women referred to an antenatal clinic for several reasons pertaining to abnormal liver functions, and those admitted to the labor room for delivery with abnormal LFTs were included in the study. The pregnant women with abnormal LFT were studied prospectively, and they were compared with pregnant women having normal LFT. The fetal and maternal outcomes were also noted.

RESULTS

 The pregnant women attending the antenatal clinic with a history of pruritus, abdominal pain, jaundice, nausea/vomiting, hypertension ascites, etc. and delivered at our facility were evaluated. One hundred and eight women had abnormal LFT defined by criteria laid down in material and methods. Eighty-seven women with normal LFT were taken for comparison. In the abnormal LFT, the main cause was intrahepatic cholestasis of pregnancy (IHCP). There were 6 (5.5%) maternal deaths in this group and none in the normal LFTs. There were 6 (5.6%) fetal deaths and 4 (4.6%) in the other group (p-value=1). The prevalence of abnormal LFT was 9.11% throughout pregnancy. Increased bilirubin and alkaline phosphatase (ALP) were significantly correlated with maternal mortality, while gestational age at birth, presence of meconium, appearance, pulse, grimace, activity, and respiration (APGAR) score, maternal mortality, and raised alkaline phosphatase level were found to be significantly associated with fetal mortality.

CONCLUSION

Patients with abnormal LFT were significantly associated with maternal morbidity and mortality. However, fetal outcomes in patients with abnormal and normal LFT were similar. Hyperbilirubinemia and raised alanine aminotransferase (ALT) were significant predictors of maternal mortality.

A spectrum of pathological changes induced by SARS-COV-2: An observational study in a cohort of pregnant women from Mizoram, India

Background

Maternal infection by SARS-CoV-2 may lead to adverse pregnancy outcomes and causes pathological changes in the placenta. However, consensus regarding characteristic pathological features is lacking. Researchof the placental histopathology in a cohort of women from Mizoram, India, was conducted to relate the SARS-CoV-2 infection's effectswith pregnancy and its outcome.

Materials and methods

The characteristics of 72 pregnant women diagnosed positive for SARS-CoV-2 who eventually delivered at Zoram Medical College Hospital, Mizoram, neonates' well-being, and histopathological features of placentas were studied.

Results

Of 72 women in this study, 59 (81.9%) gave birth at full term. Among these births, 5 were normal vaginal deliveries, while the remaining 67 (93.1%) were delivered via cesarean section. The reasons for cesarean delivery were either related to SARS-CoV-2 infection (n ​= ​49), existing obstetric problems (n ​= ​15) or fetal-distress (n ​= ​5). All deliveries resulted in live births of COVID-negative babies, with 80.6% (n ​= ​58) of the newborns having a birth weight of over 2.5 ​kg. APGAR scores ranged from 4 to 6 in 61 (84.7%) of the babies, and 10 neonates required resuscitation, of which 8 were managed in the neonatal intensive care unit (NICU). The placental histopathology showed increased fibrin thrombi in 8 cases (11.1%), while 20 cases (28%) showed focal infarction, microcalcification levels were elevated in 16 cases (22.2%), and a small percentage of cases (1.4%) exhibited small fibrotic villi and inter-villus agglutination. Placental chorioangiosis was detected in 28 (38.9%) of the cases, while avascular villi were seen in 6 cases. Meconium-stained liquor was observed in a single case. Intervillous hemorrhage was found in 42 cases, whileintervillous inflammation and increased syncytial knots were present in 14 and 5 cases, respectively. The placenta pathology of 10 neonates who required resuscitation/NICU admission was not significantly different from that of the 62 neonates who did not require it. However, a higher proportion of placenta from the asymptomatic group showed no abnormality compared to the symptomatic group (p ​= ​0.046).

Conclusion

SARS-CoV-2 infection causes a range of morphological changes and lesions in the placenta, including chorangiosis, villositis, chorioamnionitis, fetal vascular malperfusion/thrombosis, fibrin-deposition, increased syncytial-knotting, increased microcalcification, increased villous agglutination, focal infarct, intervilloushemorrhage as well as inflammation. Placental histopathological findings from this study can provide additional information to the existing literature on the subject.

Clinical spectrum and outcome of pregnancy with liver diseases - A prospective study

Objective

Liver diseases constitute a family of diseases in pregnancy which are less often studied individually. Spectrum of liver diseases directly or indirectly related to pregnancy comprise 3% of all pregnancies. The biggest challenge is to arrive at a diagnosis in such cases. With this study we aimed to study the prevalence of different Liver diseases in pregnancy in our population and its effect on fetomaternal outcome.

Material and Methods

This was a prospective observational study carried out from March 2018 to March 2020. A total of 184 pregnant women with diagnosis of some form of liver disease as evident from their symptoms, signs or biochemical investigations were included in study cohort.

Result

Primigravida accounted for majority of study cohort (44.02%). Approximately 90.21% belonged to 20-35 yrs. Age group. Intrahepatic cholestasis of pregnancy (IHCP) was the most common liver ailment (66.84%) followed by viral hepatitis (10.32%), Hyperemesis gravidarum (7.06%) and HELLP syndrome (6.52%). There was one case of Acute fatty liver of pregnancy (0.54%), four cases of Pre-eclampsia with liver dysfunction (2.17%), seven cases of Jaundice in pregnancy (3.80%) and 3 cases of pre-existing liver diseases (1.63%). 5 cases (2.71%) of antepartum eclampsia, 5 cases (2.71%) of postpartum eclampsia and 1 case (0.54%) of post-partum HELLP was seen. 33.33% patients were delivered early by induction or caesarean section because of liver dysfunction.14.67% required blood or blood products transfusion.1.63% had postpartum hemorrhage.1.08% mothers required intensive care admissions. Neonatal outcome was poor with 6.41% being growth restricted, 9.61% premature, 8.97% were intrauterine dead fetuses, 2.56% had early neonatal deaths and 7.05% needed neonatal intensive care unit admissions.

Conclusion

Timely admission, quick diagnosis and appropriate management of patients with liver diseases in pregnancy can make a significant difference in mortality and morbidity rates due to liver ailments in pregnancy.

Analysis of Causes of Hepatic Dysfunction in Obstetric Patients in India: A Systematic Review

Background

Epidemiology of liver disease in obstetric patients shows geographical variation depending upon the prevalence of preeclampsia, viral hepatitis, and tropical vector-borne diseases like malaria, leptospirosis, etc. We undertook the current systematic review to analyze the causes of hepatic dysfunction in obstetric patients in India and identify the gaps in the literature and reporting.

Materials and methods

We did a systematic review of studies reporting the causes of hepatic dysfunction in obstetric patients in India. A methodological quality assessment was done using a five-point questionnaire.

Results

A total of 21 studies qualified for evaluation. The rate of hepatic dysfunction among obstetric patients in India ranged from 0.15 to 3.3% with a mean and median rate of 1.49 and 0.93%, respectively. Preeclampsia/HELLP (mean = 36.0%, median = 31.4%, range: 3.6–83.8%) and viral hepatitis (mean = 34.1%, median = 35.5%, range: 5.1–61.8%) were the commonest causes of hepatic dysfunction. Other causes were intrahepatic cholestasis of pregnancy, acute fatty liver of pregnancy, tropical fever (malaria, leptospirosis, dengue, scrub typhus), etc. Maternal mortality ranged from 1.4 to 40% (mean = 12.6%, median = 10.0%) and perinatal mortality was between 16.4 and 38.70% (mean = 31.75%, median = 35.5%).

Conclusion

There is moderate quality evidence to show that preeclampsia/HELLP and viral hepatitis are the commonest causes of hepatic dysfunction in obstetric patients in India.

Obstetrical and gynecologic challenges in the liver transplant patient

An increasing number of childbearing agewomen undergo liver transplantation (LT) in the United States. Transplantation in this patient subgroup poses a significant challenge regarding the plans for future fertility, particularly in terms of immunosuppression and optimal timing of conception. Intrapartum LT is only rarely performed as the outcome is commonly dismal for the mother or more commonly the fetus. On the other hand, the outcomes of pregnancy in LT recipients are favorable, and children born to LT recipients are relatively healthy. Counseling on pregnancy should start before LT and continue after LT up until pregnancy, while all pregnant LT recipients must be managed by amultidisciplinary team, including both an obstetrician and a transplant hepatologist. Additionally, an interval of at least 1-2 years after successful LT is recommended before considering pregnancy. Pregnancy-induced hypertension, pre-eclampsia, and gestational diabetes mellitus are reported more commonly during the pregnancies of LT recipients than in the pregnancies of non-transplant patients. As adverse fetal outcomes, such asmiscarriage, abortion, stillbirth, or ectopic pregnancy, may occur more often than in the non-transplant population, early planning or delivery either through a planned induction of labor or cesarean section is critical to minimize the risk of complications. No significant long-term physical or phycological abnormalities have been reported in children born to LT recipients.

Elevated non-essential metals and the disordered metabolism of essential metals are associated to abnormal pregnancy with spontaneous abortion

Spontaneous abortion is a considerable threat to the physiology and mental health of the mother. The etiology of spontaneous abortion is multifactorial with complicated mechanisms, of which overexposure to non-essential metals (especially heavy metals) has been proposed to be associated with adverse birth outcomes. However, significant knowledge gaps remain to be filled in, such as the deleterious profile of non-essential metals and their interplay with essential metals in abnormal pregnancy. Under this setting, we aimed to address these challenges by conducting a cross-sectional study on 56 patients with spontaneous abortion in the 1^st trimester, by comparing to 55 healthy pregnant women in 1^st the trimester and 41 non-pregnant healthy women. Overexposure to a few non-essential metals, such as arsenic (As), antimony (Sb) and bismuth (Bi), was found in patients with spontaneous abortion, and likewise, some essential elements, such as magnesium (Mg), copper (Cu), vanadium (V), strontium (Sr) and tin (Sn), were also found to be elevated under spontaneous abortion. Further evidence of abnormal pregnancy was induced by a reduced level of internal hormones necessary for normal gestation, such as estradiol (E2) and progesterone (PRGE) in women with spontaneous abortion. Lactate dehydrogenase (LDH) and thyroid-stimulating hormone (TSH) levels were slightly increased in patients with spontaneous abortion. Comprehensive correlation analyses were carried out to identify the crucial factors that result in abortion. Our data stratified the important variables in decreasing order: PRGE, As, Mg, Sb, Sr, Sn, Bi and pregnant times in the progress of spontaneous abortion. Moreover, labyrinthine associations were uncovered between PRGE, non-essential metals and essential elements in causing spontaneous abortion. Therefore, our combined data unveiled the likely synergistic implications of elevated non-essential metals and the disordered metabolism of essential metals in abnormal pregnancy.

Liver disease in pregnancy: Medical aspects and their implications for mother and child

Liver disease during pregnancy is more common than expected and may require specialized intervention. It is important to determine if changes in liver physiology may develop into liver disease, to assure early diagnosis. For adequate surveillance of mother-fetus health outcome, liver disease during pregnancy might require intervention from a hepatologist. Liver diseases have a prevalence of at least 3% of all pregnancies in developed countries, and they are classified into two main categories: related to pregnancy; and those non- related that are present de novo or are preexisting chronic liver diseases. In this review we describe and discuss the main characteristics of those liver diseases associated with pregnancy and only some frequent pre-existing and co-incidental in pregnancy are considered. In addition to the literature review, we compiled the data of liver disease occurring during pregnancies attended at the National Institute of Perinatology in Mexico City in a three-year period. In our tertiary referral women hospital, liver disease was present in 11.24 % of all pregnancies. Associated liver disease was found in 10.8% of all pregnancies, mainly those related to pre-eclampsia (9.9% of pregnancies). Only 0.56% was due to liver disease that was co-incidental or preexisting; the acute or chronic hepatitis C virus was the most frequent in this group (0.12%). When managing pregnancy in referral hospitals in Latin America, it is important to discard liver alterations early for adequate follow up of the disease and to prevent adverse consequences for the mother and child.
