RESUMEN

This meta-analysis aims to evaluate the effectiveness of the double plasma molecular adsorption system (DPMAS) in combination with plasma exchange (PE) compared to plasma exchange alone in the treatment of Acute-on-Chronic liver failure (LF) caused by hepatitis B. Until August 31, 2023, a comprehensive search of databases including Embase, Chinese Medical Journal Full-text Database, China Biomedical Literature Database, Wan Fang Medical Network, PubMed, and the Cochrane Library was carried out using keywords like "liver failure," "acute-on-chronic liver failure," "PE," "DPMAS," and related terms. The quality of the included studies was evaluated using QUADS (quality assessment of diagnostic accuracy studies). Software Revman 5.3 was used to examine the data, while Stata 15.1 was used to run Egger's test. Following thorough screening, 452 patients who received PE alone and 429 patients who received DPMAS in addition to PE were included. Every study that was included was of a high caliber. When comparing the DPMAS plus PE group to the PE alone group, the total bilirubin reduction was considerably higher (mean difference [MD] = -49.09, 95% confidence interval [CI]: -54.84 to -43.35, p < .00001). Prothrombin activity (PTA; MD = -1.53, 95% CI: -3.29 to -0.22, p = .09), albumin (ALB; MD = -0.58, 95% CI: -1.57 to 0.41, p = .25), prothrombin time (PT; MD = -0.07, 95% CI: -1.47 to 1.34, p = .92), and platelet count (PLT; MD = -0.08, 95% CI: -1.33 to 1.66, p = .90) did not differ significantly. The improvement in international standardized ratio (INR) was significantly greater in the PE group (MD = 0.07, 95% CI (0.03, 0.10), p = .0001). When combined with DPMAS, PE has been shown to be more effective in lowering total bilirubin levels. PE can also lower INR in individuals who have hepatitis B-related ACLF. This therapeutic strategy also lessens the need for plasma transfusions.

RESUMEN

OBJECTIVE: To investigate the clinical and genetic characteristics of a case of primary ciliary dyskinesia (PCD). METHODS: We collected the clinical data on a case of PCD treated in the Department of Reproductive Medicine of Linyi People's Hospital in July 2020, detected the genes of the patient by whole-exome sequencing (WES), verified the candidate mutations by Sanger sequencing, and predicted the protein structure of the mutant gene by SWISS-MODEL. RESULTS: The proband was found with the clinical phenotypes of chronic rhinitis, bronchiectasis, visceral transposition and male infertility. WES revealed a homozygous frameshift variation of c.12890dup (p.N4297Kfs*13) in exon 74 of the DNAH5 gene, which led to the premature termination of polypeptide chain synthesis and affected the gene function. SWISS-MODEL prediction showed that some of the amino acid residues were deleted after mutation, resulting in a 3D conformational change of the protein. This variation was not recorded in the ClinVar, gnomAD and OMIM databases and, according to the relevant guidelines of the American College of Genetics and Genomics, was classified as a pathogenic variation (PVS1+PM2_P+PM3_P). CONCLUSION: The homozygous variation of the DNAH5 gene c.12890dup (p.N4297Kfs*13) may be the cause of the clinical phenotype of this case of PCD, and the above findings have enriched the variation spectrum of the DNAH5 gene.

RESUMEN

BACKGROUND: The Value of Golgi protein 73 (GP73) in the diagnosis of Hepatocellular carcinoma (HCC) remains controversial, especially in its differentiation between HCC and cirrhosis. Besides, some papers showed that GP73 levels are correlated with liver fibrosis. This study conducts a meta-analysis to evaluate the value of GP73 in diagnosing HCC and differential diagnosing HCC from liver cirrhosis. METHODS: 36 studies with a sample size of 8314 cases concerning the accuracy of GP73 in the diagnosis of HCC were selected through a systematic review. Seven of these studies included a total of 438 HCC samples and 426 cirrhosis samples and calculated the sensitivity and specificity of GP73 for differential diagnosing HCC from cirrhosis. QUADAS (quality assessment of diagnostic accuracy studies) was used to evaluate the quality of literature. Statistical analyses were performed using StataSE16 software. RESULTS: The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and the area under the curve were 0.79(95%CI 0.74-0.83),0.85(95%CI 0.80-0.89),5.4(95%CI 3.8-7.5), 0.25(95%CI 0.20-0.31), 22(95%CI 13-35), and 0.88 for GP73 diagnosing HCC;0.74(95%CI 0.64-0.81),0.70(95%CI 0.49-0.85),2.40(95%CI 1.3-4.7),0.38(95%CI 0.23-0.61),6(95%CI 2-19), and 0.78 for GP73 differential diagnosing HCC from liver cirrhosis. CONCLUSION: The results suggest that GP73 has a high diagnostic value for HCC and a moderate value for differential diagnosis of HCC from liver cirrhosis.

RESUMEN

Energy saving and emission reduction have always been the goal of separation and catalysis pursued in industrial production. Metal-organic frameworks (MOFs) are leading porous crystal materials with unique advantages in these fields. Based on an amide-modified ligand 5-(ethyl oxamate)-isophthalic acid (H2EtL), a new porous indium-organic framework (Me2NH2)1.5[In1.5L2]·2DMF·2H2O (1) was synthesized and structurally characterized. The unique porous environment gives it dual functional advantages in separation and catalysis. At room temperature, 1 possesses excellent adsorption capacities for C2 hydrocarbons and CO2, showing good separation behaviors for C2 hydrocarbons/CO2 on CH4 and C2H2 on CO2, which is conducive to efficient purification of CH4 and C2H2 confirmed by the breakthrough experiment. Meanwhile, catalytic results indicate that 1 can be used as a good catalyst for effective fixation of CO2 under mild conditions to form cyclic carbonates.

RESUMEN

The new indium-based organic framework {(Me2NH2)[In(BDPO)]·DMF·2H2O}n (1) was successfully constructed by using the oxalamide group modified ligand N,N'-bis(isophthalic acid)oxalamide (H4BDPO). This framework presents a 2-fold interpenetrating structural characteristic, and the unique polar pore environment leads to a high capture ability for CO2, C2Hn and CH3OH and good separation ability for CO2 and C2Hn over CH4 as well as for CH3OH over C2H5OH, which was further verified by an ideal adsorbed solution theory (IAST) calculation. Theoretical simulations pointed out the possible adsorption sites of different adsorbed gases in 1. In addition, the excellent chemical stability and strong luminescence of 1 give it an effective selective detection ability for 2,6-dichloro-4-nitroaniline (DCN) in water with a low detection limit of 3.85 ppm, and the detection mechanism is discussed in detail.

RESUMEN

With the aid of a pyridyl tetracarboxylate ligand, 2,5-bis(2',5'-dicarboxylphenyl)pyridine (H4L), two indium-organic frameworks, [In2(L)(OH)2]·2DMF·2H2O (1) and [Me2NH2][In(L)]·2.5NMF·4H2O (2), with (6,8)- and (4,4)-connected nets have been constructed in different solvent systems. Both 1 and 2 exhibit high thermal and chemical stability. Gas sorption behavior of 1 and 2 for N2, C2H2, C2H4, CO2, and CH4 indicate excellent separation selectivities of C2Hx/CH4 and CO2/CH4. Furthermore, 1 possesses a high density of Brønsted sites and shows efficient catalytic conversion for CO2 cycloaddition with epoxides. Meanwhile, luminescence investigations reveal that 2 can detect nitrofurazone efficiently.

RESUMEN

An ongoing outbreak of a novel coronavirus infection in Wuhan, China since December 2019 has led to 31,516 infected persons and 638 deaths across 25 countries (till 16:00 on February 7, 2020). The virus causing this pneumonia was then named as the 2019 novel coronavirus (2019-nCoV) by the World Health Organization. To promote the data sharing and make all relevant information of 2019-nCoV publicly available, we construct the 2019 Novel Coronavirus Resource (2019nCoVR, https://bigd.big.ac.cn/ncov). 2019nCoVR features comprehensive integration of genomic and proteomic sequences as well as their metadata information from the Global Initiative on Sharing All Influenza Data, National Center for Biotechnology Information, China National GeneBank, National Microbiology Data Center and China National Center for Bioinformation (CNCB)/National Genomics Data Center (NGDC). It also incorporates a wide range of relevant information including scientific literatures, news, and popular articles for science dissemination, and provides visualization functionalities for genome variation analysis results based on all collected 2019-nCoV strains. Moreover, by linking seamlessly with related databases in CNCB/NGDC, 2019nCoVR offers virus data submission and sharing services for raw sequence reads and assembled sequences. In this report, we provide comprehensive descriptions on data deposition, management, release and utility in 2019nCoVR, laying important foundations in aid of studies on virus classification and origin, genome variation and evolution, fast detection, drug development and pneumonia precision prevention and therapy.

RESUMEN

Aconiti Lateralis Radix Praeparata and Glycyrrhizae Radix et Rhizoma is a representative acid-alkali drug pair,commonly used in clinical application of traditional Chinese medicine( TCM). Its unique compatibility connotation fully embodied the wisdom of ancient people in drug use. In order to more comprehensively and deeply understand the scientific connotation of the compatibility of the two drugs,pharmacy workers have studied the mechanism of reducing toxicity and enhancing efficacy through their compatibility from the perspectives of chemistry,pharmacology and toxicology. On the basis of combing the previous research work,this paper interpreted the unique compatibility connotation from the three-level system of reducing the content of toxic components in vitro by hydrolysis,lipid exchange and formation of associations,the active constituents of Glycyrrhizae Radix et Rhizoma affecting the metabolism of toxic components and direct antagonism of the toxic effects of aconite in vivo. The existing problems and controversies of the modern mechanism of their compatibility were also proposed,providing a reference for further in-depth studies.

RESUMEN

OBJECTIVE: To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. METHODS: We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases (ASCVD) among 8,252 participants aged ⪖ 40 years without diabetes from Jiading district, Shanghai, China. RESULTS: Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid (all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia (all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios (ORs) [95% confidence intervals (CIs)] for the highest quartiles for high Framingham risk were 3.00 (2.00-4.50) in men and 2.95 (1.08-8.43) in women. The multivariate adjusted ORs (95% CIs) for the highest quartile for high ASCVD risk were 1.93 (1.17-3.17) in men and 4.53 (2.57-7.98) in women. CONCLUSION: Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.

RESUMEN

Despite substantial progress in medical care, the morbidity rate of diabetic nephropathy (DN) remains high in patients with diabetes. Evidence suggests that connective tissue growth factor (CTGF) induced podocyte injury may contribute to DN and CTGF inhibition could reduce albuminuria. However, to date the mechanisms involved in the effect of CTGF on podocyte injury have not been fully understood. The aim of this study is to investigate the effects of therapeutic CTGF antibody on glomerular ß-catenin expression and podocyte epithelial-mesenchymal transition (EMT) in diabetic mice. C57BL/6J mice were randomly divided into three groups as the following: the control, DN, and DN treated by CTGF antibody group. DN was induced by a single intraperitoneal injection of streptozotocin and then CTGF antibody was administrated three times per week for 8 weeks. Urinary albumin excretion, mesangial proliferation and matrix deposition, and ß-catenin expression in glomeruli at mRNA and protein level were all increased in DN mice compared to that in the control. Besides, the development of EMT in podocytes from diabetic mice, demonstrated by the downregulation of nephrin and upregulation of desmin in glomeruli, was detected. Furthermore, blocking CTGF by specific antibody reduced albuminuria, prevented the overexpression of CTGF, as well as ß-catenin, in glomeruli and subsequently ameliorated podocyte EMT in DN mice. In summary, this study suggested that CTGF antibody protected podocytes against injury in DN mice by reducing ß-catenin overexpression and preventing podocyte EMT, which might provide new insight into the mechanism of CTGF inhibition in the treatment of DN.

RESUMEN

To compare the amino acid metabolic profiling in urine of spontaneously hypertensive rats (SHR) and normal Wistar rats, and investigate the regulatory effect of extract from Coreopsis tinctoria on blood pressure and amino acid metabolic profiling in SHR. Right aged SHR and Wistar rats were housed to fit the new environment for 2 weeks. After that, their systolic pressure(SBP), diastolic pressure(DBP) were measured and urine was collected. Amino acids profiles for SHR and Wistar rats were acquired by using AQC precolumn derivatization HPLC-fluorescence method, and then partial least squares discriminant analysis(PLS-DA) was applied to facilitate differentiation and determine metabolic differences between collected samples from two groups of rats. Consequently, 40 SHR were randomly divided into 5 groups: model group, high, middle, low dosage groups of C. tinctoria extract (3.2, 1.6,0.8 g•kg⁻¹), and captopril group (4 mg•kg⁻¹). They were treated for 4 weeks by ig administration, and then their urine samples were collected to determine the amino acid metabolic profiling in various groups. After treatment for 4 weeks, as compared with Wistar group, serine, alanine, tyrosine, and cystine in the amino acid metabolic profiling were significantly increased in SHR group. As compared with SHR model group, threonine and methionine were decreased significantly in captopril group (P<0.01); amino acid metabolism was changed to different degrees in high, middle, and low dosage groups of C. tinctoria extract, and the threonine in low dose group was significantly decreased (P<0.01); serine and threonine were decreased (P<0.05), and valine, methionine and lysine were significantly decreased (P<0.01) in middle dose group; threonine, valine, methionine and lysine were significantly decreased in large dose group (P<0.01). The results showed that middle and high doses of extract from C. tinctoria could significantly improve disturbance of amino acid metabolism, help to further clarify the drug property research of C. tinctoria, and provide data support for amino acid metabolic pathway abnormalities in hypertension patients.

RESUMEN

BACKGROUND: Recent studies indicate that consumption of the different calorie diet may be an important way to accelerate or slow the neurodegenerative disorder related to age. Long-term consumption of a high-calorie diet affects the brain and increase the risk of neurodegenerative disorders. And consumption of a low-calorie diet (caloric restriction, CR) could delay aging, and protect the central nervous system from neurodegenerative disorders. The underlying mechanisms have not yet been clearly defined. METHOD: Thirty 6-week-old C57/BL6 mice were randomly assigned to a NC group (fed standard diet, n = 10), a CR group (fed a low-calorie diet, n = 10) or a HC group (fed a high-calorie diet, n = 10) for 10 months. Body weight was measured monthly. Learning and memory capacity were determined by Morris water maze. Pathological changes of the hippocampus cells were detected with HE and Nissl staining. The expression of GFAP was determined by immunofluorescence and western blot. The expression of mTOR, S6K and LC3B in the hippocampus was determined by immunofluorescence. RESULTS: After feeding for 10 months, compared with mice in the NC group, mean body weight was significantly higher in the HC group and significantly lower in the CR group. The result of Morris water maze showed that compared with mice in the NC group, the learning and memory capacity was significantly increased in the CR group, and significantly decreased in the HC group. HE and Nissl staining of the hippocampus showed cells damaged obviously in the HC group. In the hippocampus, the expression of GFAP, mTOR and S6K was increased in the HC group, and decreased in the CR group. The expression of LC3B was decreased in the HC group, and increased in the CR group. CONCLUSIONS: Long-term consumption of a high-calorie diet could inhibit autophagy function, and facilitate neuronal loss in the hippocampus, which in turn aggravate age-related cognition impairment. And consumption of a low-calorie diet (caloric restriction, CR) could enhance the degree of autophagy, protect neurons effectively against aging and damage, and keep learning and memory capacity better.

RESUMEN

Misuse and overuse of antibiotics have led to serious resistance problems that pose a grave threat to human health. How to solve the increasing antibiotic resistance problem is a huge challenge. Besides the traditional strategy of developing novel antimicrobial agents, exploring ways to enhance the lethal activity of antibiotics currently available is another feasible approach to fight against resistance. Recent studies showed that ROS plays an important role in regulating both antibiotic resistance and antimicrobial lethality. ROS produced by sublethal levels of antibiotic induces antibiotic resistance through activating drug efflux pumps via MarR(Multiple antibiotic resistance repressor)-MarA(Multiple antibiotic resistance activator), triggers the protective function against stress via SoxR (Superoxide response transcriptional regulator)-SoxS (Superoxide response transcription factor), and promotes mutagenesis by induction of SOS system. On the contrary, ROS triggered by lethal levels of antibiotic promotes bacterial killing and suppresses resistance. In addition to the concentration of antibiotic, the role of ROS in mediating antimicrobial resistance and bacterial killing is also regulated by a series of genetic regulators (e.g. MazEF, Cpx, SoxR, MarRAB). Thus, how ROS contribute to antimicrobial resistance and bacterial killing is complex. In this review, we summarized the mechanism of ROS in regulating antibiotic resistance and antimicrobial lethality, which may provide references and guidance for finding new ways to enhance antimicrobial lethality of currently available antimicrobials and battling antibiotic resistance.

RESUMEN

The evolution of water DOC and COD, and the source, chemical structure, humification degree and redox of dissolved organic matter (DOM) in a constructed wetland of Xiao River, Hebei, was investigated by 3D excitation--emission matrix fluorescence spectroscopy coupled with ultraviolet spectroscopy and chemical reduction, in order to explore the geochemical processes and environmental effects of DOM. Although DOC contributes at least 60% to COD, its decrease in the constructed wetland is mainly caused by the more extensive degradation of elements N, H, S, and P than C in DOM, and 65% is contributed from the former. DOM is mainly consisted of microbial products based on proxies f470/520 and BIX, indicating that DOM in water is apparently affected by microbial degradation. The result based on PARAFAC model shows that DOM in the constructed wetland contains protein-like and humus-like components, and Fulvic- and humic-like components are relatively easier to degrade than protein-like components. Fulvic- and humic-like components undergo similar decomposition in the constructed wetland. A common source of chromophoric dissolved organic matter (CDOM) and fluorescent dissolved organic matter (FDOM) exists; both CDOM and FDOM are mainly composed of a humus-like material and do not exhibit selective degradation in the constructed wetland. The proxies E2 /E3, A240-400, r(A, C) and HIX in water have no changes after flowing into the constructed wetland, implying that the humification degree of DOM in water is hardly affected by wet constructed wetland. However, the constructed wetland environment is not only beneficial in forming the reduced state of DOM, but also facilitates the reduction of ferric. It can also improve the capability of DOM to function as an electron shuttle. This result may be related to the condition that the aromatic carbon of DOM can be stabilized well in the constructed wetland.

RESUMEN

Allicin is the internationally accepted active substance of garlic, and has cardiovascular protective effect. This research was designed to investigate the effect of allicin on myocardial fibrosis after myocardial infarction and explore the relationship between the effect and TGFß1/Smads signaling pathway. The rat myocardial infarction model were made by ligating the left anterior desending coronary artery. The drugs were administered intraperitoneally 24 h after the operation. After 21 days, the rats were sacrificed and myocardial collagen fibres were observed by Masson staining. The protein expression of Ⅰ, Ⅲ collagen and TGFß1, Smad3, Smad7 in the myocardium was measured by the immunohistochemistry. The results showed that myocardial fibrosis was serious and the expression of Ⅰ, Ⅲ collagen was increased in model group. After treatment with allicin, the myocardial fibrosis could be relieved markedly, and the expression of collagen was down-regulated. Meanwhile, TGFß1 and Smad3 in heart tissue could be down-regulated and Smad7 could be up-regulated in allicin groups. So allicin may exhibit anti-myocardial fibrosis effect on rats, and the mechanism of this is related to TGFß/Smads signal transduction.

RESUMEN

To study the effect of plant protein and animal protein on amino acid metabolism spectrum of Qi and Yin deficiency type 2 diabetic rats. 110 male SD rats were randomly divided into blank group (n=10), diabetic model group (n=20), disease-symptoms group (n=80). The rats of blank group received ordinary feeding, while other groups were fed with high sugar and fat diets. During the whole process of feeding, rats of disease-symptoms group were given with Qingpi-Fuzi (15.75 g•kg⁻¹) once a day through oral administration. Five weeks later, the rats were given with a low dose of STZ (40 mg•kg⁻¹) by intraperitoneal injection to establish experimental diabetic models. Then the models were randomly divided into disease-symptoms group 1 (Qi and Yin deficiency diabetic group, 15.75 g•kg⁻¹), disease-symptoms group 2 (plant protein group, 0.5 g•kg⁻¹), disease-symptoms group 3 (animal protein group, 0.5 g•kg⁻¹), disease-symptoms group 4 (berberine group, 0.1 g•kg⁻¹). The drugs were given for 4 weeks by gavage administration. After 4 weeks of protein intervention, the abdominal aortic blood was collected and serum was isolated to analyze its free amino acid by using AQC pre-column derivatization HPLC and fluorescence detector. Four weeks after the protein intervention, plant protein, animal protein and berberine had no obvious effect on body weight and blood sugar in type 2 diabetic rats. As compared with animal protein group, histidine and proline(P<0.01), serine, glycine, threonine, alanine, tyrosine, valine, methionine, bright+isoleucine, phenylalanine and lysine(P<0.05)changed a lot in rats serum of plant protein group.The results showed that gavage administration of protein would produce effects on amino acid metabolism of Qi and Yin deficiency type 2 diabetic SD rats. Symbolic differential compounds could be found through metabonomics technology, providing experimental basis for early warning of type 2 diabetes and diagnosis of Qi and Yin deficiency syndrome.

RESUMEN

In recent years, more elderly patients with gastrointestinal cancers have been undergoing surgery. As one of main postoperative complications, postoperative delirium (POD) is harmful and difficult to prevent and treat. Prevention, diagnosis and treatment to POD properly and ptomptly can promote the patient's overall recovery. However, health care providers still have many problems for POD to face in elderly,with gastrointestinal cancers during the clinical care. In this paper, Etiology, damages, prevention, diagnosis and treatment of POD in elderly with gastrointestinal cancer were reviewed, and the prospect of POD was also discussed.

RESUMEN

BACKGROUND/AIMS: The aim of this study was to explore the potential role of serum high-sensitivity C-reactive protein (hs-CRP) in the pathogenic process of chronic hepatitis B. METHODOLOGY: A total of 380 patients with chronic hepatitis B were included in this study. All patients received the concentrations of serum hs-CRP, Hepatitis B sero-markers, serum HBV-DNA loads, liver function parameters and liver stiffness were measured, and in which 172 patients undertaken liver biopsy and immunohistochemistry analysis. RESULTS: Serum hs-CRP concentration in patients with the chronic hepatitis B (2.38 ± 5.52) was significantly higher than healthy controls (0.60 ± 0.53), P < 0.05. The area under ROC curve in fibrosis S4 and S3 is 0.826 and 0.78. The sensitivity and specificity of hs-CRP for fibrosis S3 and S4 diagnosis were 81.8%, 80% and 73.4%, 76.2% respectively (cut off: 1.01 mg/ml, 1.11 mg/l). CONCLUSIONS: C-reactive Protein are associated with HBV replication, liver damage and fibrosis in patients with chronic hepatitis B, and serum High-sensitivity C-reactive Protein may be a marker for diagnosing significant fibrosis in patients with chronic hepatitis B, and can reflect the severity of liver damage.

RESUMEN

OBJECTIVE: To observe the clinical efficacy of combination therapy with peg-IFNalpha and adefovir (CPIA) in women who were hepatfis B virus (HBV) carriers and had just given birth and received telbivudine (LdT) during pregnancy for prevention of mother-to-child transmission. METHODS: One-hundred-and-fifty third trimester-pregnant women who were HBV carriers with highly-viremic were treated with LdT until time of birth. After delivery, those women with alanine aminotransferase (ALT) level exceeding two times the upper limit of normal and HBV DNA level that had decreased more than 31 gIU/mL or hepatitis B e antigen (HBeAg) titer that had decreased more than 50% were switched to CPIA for 96 weeks. RESULTS: Following delivery, 45 of the women were switched to the CPIA treatment, of which 91.1% (41/45) achieved virological response, 55.6% (25/45) achieved HBeAg clearance or seroconversion, and 26.7% (12/45) achieved hepatitis B surface antigen (HBsAg) clearance or seroconversion.The immediate post-delivery (and pre-CPIA) levels of HBeAg and HBV DNA were negatively associated with HBeAg clearance. Ninety-eight of the total study participants stopped the LdT treatment and there were no cases of significant deterioration of liver function. CONCLUSION: Pregnant women who are HBV carriers and receive LdT for protection against mother-to-child transmission, and who show significant ALT elevation and decreased HBeAg titer and/or reduced HBV DNA after delivery, may be good candidates for the CPIA therapy following delivery.
