Süzen Çaypınar S, Oğlak SC, Behram M, Gedik Özköse Z, Sezer S, Karakaş S. Serum autotaxin levels correlate with the severity of pruritus in intrahepatic cholestasis of pregnancy. J Obstet Gynaecol Res 2022; 48:3093-3102. [PMID: 36164271 DOI: 10.1111/jog.15444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 08/25/2022] [Accepted: 09/14/2022] [Indexed: 11/28/2022]
Abstract
PURPOSE This study aimed to examine autotaxin (ATX) concentrations in the serum of pregnant women complicated with intrahepatic cholestasis of pregnancy (ICP) and compare them with individuals with uncomplicated healthy pregnancies. METHODS This prospective case-control study took place with 83 pregnant women. The study group included 43 pregnant women presenting with a singleton pregnancy diagnosed with ICP in their third trimester of pregnancy. The diagnostic power of the ATX variable was examined by receiver operating characteristic analysis, and the cut-off value calculated according to the Youden index was summarized with the related sensitivity and specificity points. RESULTS The mean serum concentration of maternal ATX was significantly higher in the ICP cases (8.91 ± 2.69 pg/mL) compared to the pregnant women in the control group (3.59 ± 1.39 ng/mL, p < 0.001). According to the Youden index, a 5.80 ng/mL cut-off value of serum ATX concentrations can be used to diagnose ICP with 97.7% sensitivity and 97.5% specificity. A significant highly positive correlation was found between maternal serum ATX levels and maternal serum total bile acid levels (r = 0.633 and p < 0.001) and itch intensity, which was objectified by the visual analog scale score (r = 0.951 and p < 0.001). CONCLUSION Maternal serum ATX levels were significantly increased in ICP patients as compared with healthy pregnant women. Also, serum ATX activity was highly correlated with the itch intensity. We consider that ATX might represent a robust, accurate, and reliable circulating biomarker to diagnose ICP.

Deep Learning Algorithm-Based Magnetic Resonance Imaging Feature-Guided Serum Bile Acid Profile and Perinatal Outcomes in Intrahepatic Cholestasis of Pregnancy. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:8081673. [PMID: 35707042 PMCID: PMC9192280 DOI: 10.1155/2022/8081673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 05/06/2022] [Accepted: 05/09/2022] [Indexed: 11/27/2022]
Abstract
This study was aimed to explore magnetic resonance imaging (MRI) based on deep learning belief network model in evaluating serum bile acid profile and adverse perinatal outcomes of intrahepatic cholestasis of pregnancy (ICP) patients. Fifty ICP pregnant women diagnosed in hospital were selected as the experimental group, 50 healthy pregnant women as the blank group, and 50 patients with cholelithiasis as the gallstone group. Deep learning belief network (DLBN) was built by stacking multiple restricted Boltzmann machines, which was compared with the recognition rate of convolutional neural network (CNN) and support vector machine (SVM), to determine the error rate of different recognition methods on the test set. It was found that the error rate of deep learning belief network (7.68%) was substantially lower than that of CNN (21.34%) and SVM (22.41%) (P < 0.05). The levels of glycoursodeoxycholic acid (GUDCA), glycochenodeoxycholic acid (GCDCA), and glycocholic acid (GCA) in the experimental group were dramatically superior to those in the blank group (P < 0.05). Both the experimental group and the blank group had notable clustering of serum bile acid profile, and the experimental group and the gallstone group could be better distinguished. In addition, the incidence of amniotic fluid contamination, asphyxia, and premature perinatal infants in the experimental group was dramatically superior to that in the blank group (P < 0.05). The deep learning confidence model had a low error rate, which can effectively extract the features of liver MRI images. In summary, the serum characteristic bile acid profiles of ICP were glycoursodeoxycholic acid, glycochenodeoxycholic acid, and glycocholic acid, which had a positive effect on clinical diagnosis. The toxic effects of high concentrations of serum bile acids were the main cause of adverse perinatal outcomes and sudden death.

Serum Exosomes MicroRNAs Are Novel Non-Invasive Biomarkers of Intrahepatic Cholestasis of Pregnancy. Front Endocrinol (Lausanne) 2022; 13:832577. [PMID: 35600587 PMCID: PMC9114354 DOI: 10.3389/fendo.2022.832577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 03/25/2022] [Indexed: 11/17/2022] Open
Abstract
Background Intrahepatic cholestasis of pregnancy (ICP) is closely related to the occurrence of adverse outcomes. Currently, total bile acids (TBAs) are the only diagnostic index for ICP, and its sensitivity and specificity have certain limitations. In this study, we aimed to develop potential biomarkers for the diagnosis of ICP. Methods Sixty pregnant women diagnosed with ICP and 48 healthy pregnant controls were enrolled in this study. We used the Agilent microRNA (miRNA) array followed by quantitative reverse transcriptase polymerase chain reaction assays to identify and validate the serum exosome miRNA profiles in ICP and healthy pregnant controls. We employed bioinformatics to identify metabolic processes associated with differentially expressed serum exosome miRNAs. Results The expression levels of hsa-miR-4271, hsa-miR-1275, and hsa-miR-6891-5p in maternal serum exosomes were significantly lower in ICP patients compared to controls; the diagnostic accuracy of hsa-miR-4271, hsa-miR-1275, and hsa-miR-6891-5p was evaluated with the area under the receiver operating characteristic curve (AUC) values of 0.861, 0.886, and 0.838, respectively. Multiple logistic regression analysis showed that a combination of the levels of hsa-miR-4271and hsa-miR-1275 afforded a significantly higher AUC (0.982). The non-error rate of a combination of all three exosome miRNAs was the highest (95%), thus more reliable ICP diagnosis. The expression levels of all three exosome miRNAs were negatively associated with TBAs. Furthermore, according to bioinformatics analysis, the three exosome miRNAs were related to lipid metabolism, apoptosis, oxidative stress, and the Mitogen Activated Protein Kinase (MAPK) signaling pathway. Conclusions This study may identify the novel non-invasive biomarkers for ICP and provided new insights into the important role of the exosome miRNA regulation in ICP.

Effect of intrahepatic cholestasis of pregnancy on infantile food allergy: A retrospective longitudinal study cohort in Southwest China. Eur J Obstet Gynecol Reprod Biol 2022; 272:110-115. [PMID: 35303672 DOI: 10.1016/j.ejogrb.2022.03.026] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 02/14/2022] [Accepted: 03/11/2022] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Intrahepatic cholestasis of pregnancy has been consistently associated with a higher incidence of adverse pregnancy outcomes. Previous studies mainly focused on the effects of intrahepatic cholestasis of pregnancy on pregnant mothers and fetuses, and few studies reported the postpartum growth and development of fetuses in pregnant women with intrahepatic cholestasis of pregnancy. The aim of this study was to investigate impact of maternal serum total bile acid levels on maternal and neonatal outcomes as well as child growth and food allergy. MATERIAL AND METHODS A retrospective longitudinal cohort investigation was carried out among 751 pregnant women with intrahepatic cholestasis of pregnancy at 30-32 weeks of gestation from the Longitudinal Intrahepatic Cholestasis of Pregnancy Study (LoICPS). Data on the characteristics of the mothers and neonates were collected. Infant growth data and food sensitivities were also collected. RESULTS In our cohort, the average maternal serum total bile acid level was 35.09±30.02 μmol/L, with 58.8% of mothers suffering from mild intrahepatic cholestasis of pregnancy and 29.2% suffering from severe intrahepatic cholestasis of pregnancy. Positive correlations were found between maternal serum total bile acid levels and twin pregnancy (beta-value: 11.55, 95% CI: 2.89 - 20.20. P = 0.009) and meconium stained amniotic fluid (beta-value: 14.64, 95% CI: 9.41 - 19.87. P < 0.001). In addition, the infants of mothers with severe intrahepatic cholestasis of pregnancy were more likely to be allergic to foods at 6 months. CONCLUSIONS This study suggested that despite pregnant women with intrahepatic cholestasis of pregnancy taking ursodeoxycholic acid tablets and cesarean section before expected date of childbirth, the perinatal outcome of newborns partially improving, the incidence of infantile food allergy was still increased.

Abstract
Liver disease is a great danger to human health. The determination of blood level of Cholyglycine acid (CG) is a vital biomarker for the assessment of liver function in clinic, which is contribute to the diagnosis of liver diseases. Thus, establishing accuracy, rapid and convenient
method for the detection of glycolic acid is of great significance. In this study, a time-resolved-fluorescence (TRF) lateral flow assay for rapid detection of CG was development. The analytical detection limit (mean of zero-2 SD) was 0.06 μg/mL The method showed good linearity in
the range of 0.2–40 g/mL and was not affected by biomolecules with similar structure to CG. The analytical mean recovery of control was between 90–110% and the imprecision of intra- and inter-assay of CVs was less than 10%. No significant matrix effect was observed in saline, serum,
plasma or whole blood. A good correlation was found with the homogeneous enzyme immunoassay (HEIA) assay (slopes 1.0463, y-intercepts 0.2721 μg/mL, R = 0.989, n = 50, P < 0.001). The CG TRF analysis could provide reproducible and quantitative information
about the state of liver in a few minutes, which is suitable for the detection of liver diseases in point-of-care-testing (POCT) conditions.

Antipruritic Effect of Nalbuphine, a Kappa Opioid Receptor Agonist, in Mice: A Pan Antipruritic. Molecules 2021; 26:molecules26185517. [PMID: 34576988 PMCID: PMC8466557 DOI: 10.3390/molecules26185517] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 09/03/2021] [Accepted: 09/07/2021] [Indexed: 11/17/2022] Open
Abstract
Antipruritic effects of kappa opioid receptor (KOR) agonists have been shown in rodent models of acute and chronic scratching (itchlike behavior). Three KOR agonists, nalfurafine, difelikefalin, and nalbuphine, are in clinical studies for antipruritic effects in chronic itch of systemic and skin diseases. Nalfurafine (in Japan) and difelikefalin (in the USA) were approved to be used in the treatment of chronic itch in hemodialysis patients. The FDA-approved nalbuphine has been used in clinic for over 40 years, and it is the only narcotic agonist that is not scheduled. We aimed to study (a) antiscratch activity of nalbuphine against TAT-HIV-1 protein (controls HIV transcription)-, deoxycholic acid (DCA, bile acid)-, and chloroquine (CQ)-induced scratching in a mouse model of acute itch; and (b) whether the effect of nalbuphine is produced via KORs. First, dose-responses were developed for pruritogens. Mice were pretreated with nalbuphine (0.3-10 mg/kg) and then a submaximal dose of pruritogens were administered and the number of scratching bouts was counted. To study if the antiscratch effect of nalbuphine is produced via KOR, we used KOR knock out mice and pharmacologic inhibition of KORs using nor-binaltorphimine, a KOR antagonist. For this aim, we used CQ as a pruritogen. We found that: (a) TAT-HIV-1 protein elicits scratching in a dose-dependent manner; (b) nalbuphine inhibits scratching induced by TAT-HIV-1, DCA, and CQ dose-dependently; and (c) nalbuphine inhibits scratching induced by CQ through KORs. In conclusion, nalbuphine inhibits scratching elicited by multiple pruritogens.
