Eur J Obstet Gynecol Reprod Biol 2018; 227:60-66. [PMID: 29886319 DOI: 10.1016/j.ejogrb.2018.05.042] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Revised: 04/20/2018] [Accepted: 05/31/2018] [Indexed: 12/21/2022]
Abstract
OBJECTIVE Hepatocyte Growth Factor (HGF) plays a role in the migration and morphogenesis of different cell types and tissues. Preeclampsia (PE) is associated with deficient trophoblast invasion and placental insufficiency; hence HGF production is expected to be compromised. This study therefore aimed to immunolocalize and morphometrically analyse placental HGF in normotensive versus PE pregnancies stratified by HIV status and gestational age. STUDY DESIGN Normotensive (N; n = 40) and preeclamptic (PE; n = 80) women were stratified by HIV status (HIV- and HIV+), and gestational age i.e. early onset of PE (EOPE; <34 weeks) and late onset of PE (LOPE; ≥34 weeks). Placental tissues were stained using conventional immunohistochemistry, performed using mouse anti-human HGF antibody. Morphometric image analysis was performed using Zeiss Axio-Vision software. RESULTS HGF was immuno-localized within the syncytiotrophoblast, cytotrophoblast, endothelial and fibroblast-like cell populations of both conducting and exchange villi. Based on pregnancy type, HGF immunoexpression within the conducting villi was significantly different between Nvs EOPE (p = 0.0372) and EOPE vs LOPE (p = 0.0006). Within the exchange villi, no significant difference of HGF immunostaining was noted between N vs EOPE and N vs LOPE. A down-regulation of HGF immuno-expression was observed in LOPE compared to other groups within both villi types, albeit non-significant. Based on HIV status, no significant difference in HGF immuno-expression was demonstrated between HIV- vs HIV + within the exchange and conducting villi. However, the expression of HGF in HIV- group was elevated in both villi types. Across the groups, a significant difference was found between N+ vs EOPE- (p = 0.0207), EOPE+ vs LOPE- (p = 0.0036) and EOPE- vs LOPE- (p = 0.0016) of the conducting villi while no significant difference was found within the exchange villi. CONCLUSION This novel study demonstrates that HGF was two-fold higher in conducting compared to exchange villi irrespective of the pregnancy type. HIV infection does not influence HGF expression within the conducting and exchange villi. The HGF/c-MET receptor complex may modulate the ligand expression within the placenta.

Abstract
This study investigated biological activities including antioxidative stress, anti‐inflammation, and anti‐insulin resistance of Anoectochilus burmannicus aqueous extract (ABE). The results showed abilities of ABE to scavenging DPPH and ABTS free radicals in a dose‐dependent manner. Besides, ABE significantly reduced nitric oxide (NO) production in the lipopolysaccharide (LPS)‐treated RAW 264.7 via inhibition of mRNA and protein expressions of nitric oxide synthase (iNOS). The LPS‐induced mRNA expressions of cyclooxygenase‐2 (COX‐2) and interleukin 1β (IL‐1β) were suppressed by ABE. Moreover, ABE exerted anti‐insulin resistance activity as it significantly improved the glucose uptake in tumor necrosis factor (TNF)‐α treated 3T3‐L1 adipocytes. In addition, ABE at the concentration of up to 200 μg/mL was not toxic to human peripheral blood mononuclear cells (PBMCs) and did not induce mutations. Finally, the results of our study suggest the potential use of A. burmannicus as anti‐inflammatory, anti‐insulin resistance agents, or food supplement for prevention of chronic diseases.

Abstract
Background Obesity, an epidemic among West Virginia children, as well as insulin resistance (IR), is well-established contributors to nonalcoholic steatohepatitis (NASH). Progression of NASH can lead to hepatic fibrosis and cirrhosis, making early detection imperative. The standard for diagnosing NASH is histologically via liver biopsy, which is highly invasive and generally contraindicated in children. By studying serum biomarkers associated with NASH, we aim to identify high risk children who can benefit from a less invasive, alternative approach to the early detection of NASH. Methods Seventy one children were prospectively recruited and divided into 3 groups: normal weight without IR (control), obese without IR, and obese with IR. Serum samples were drawn for each patient and biomarker levels were assessed via ELISA kits. Results Obese without IR and obese with IR patients had significantly elevated levels of lipid metabolism and accumulation markers (FGF-21, NEFA, FATP5, ApoB), oxidative stress markers (dysfunctional HDL, 8-Isoprostane), inflammatory markers(dysfunctional HDL, CK-18) and apoptosis markers (CK-18) compared to control patients (p<0.02). Bilirubin (an antioxidant) was significantly decreased in the obese without IR and obese with IR patients compared to control (p<0.02). Conclusion This study showed a correlation between obesity, IR, and biomarkers associated with NASH in pediatrics patients from West Virginia, with obese with IR patients showing the strongest correlation. These findings support the clinical application of these serum biomarkers as a less invasive method for early detection of NASH and hepatic fibrosis.

Abstract
BACKGROUND AND OBJECTIVES Obesity and HIV-1/HAART-associated lipodystrophy syndrome (HALS) share clinical, pathological and mechanistic features. Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) is a multifunctional cytokine that plays an important role in obesity and related diseases. We sought to explore the relationship between HALS and circulating levels of soluble (s) TWEAK and its scavenger receptor sCD163. METHODS This was a cross-sectional multicenter study of 120 HIV-1-infected patients treated with a stable HAART regimen; 56 with overt HALS and 64 without HALS. Epidemiological and clinical variables were determined. Serum levels of sTWEAK and sCD163 levels were measured by ELISA. Results were analyzed with Student's t-test, Mann-Whitney U and χ2 test. Pearson and Spearman correlation were used to estimate the strength of association between variables. RESULTS Circulating sTWEAK was significantly decreased in HALS patients compared with non-HALS patients (2.81±0.2 vs. 2.94±0.28 pg/mL, p = 0.018). No changes were observed in sCD163 levels in the studied cohorts. On multivariate analysis, a lower log sTWEAK concentration was independently associated with the presence of HALS (OR 0.027, 95% CI 0.001-0.521, p = 0.027). CONCLUSIONS HALS is associated with decreased sTWEAK levels.

Abstract
The evolution of hepatitis C virus (HCV) quasispecies in patients with HIV-1 coinfection is not fully understood. The HCV-1a quasispecies heterogeneity was analyzed at inter and intra-host levels along 7.6 years in 21 coinfected patients that showed different virological and immunological responses to highly active antiretroviral therapy (HAART). Two to nine serial samples were subjected to direct and clonal sequence analyses of the envelope glycoprotein 2 (E2) gene. E2-based phylogenies, intra-host HCV evolution and evolutionary rates, as well as dynamics of the quasispecies heterogeneity parameters were evaluated. Bayesian coalescent phylogenies indicated complex evolutionary histories, revealing some viral lineages that persisted along the follow up and others that were detectable at a single or some sampling times, suggesting the occurrence of emergence-extinction cycles. HCV quasispecies underwent very rapid evolution in HAART-treated patients (~3.1 × 10(-2) sub/site/year) following the recovery of the host immunocompetence irrespectively of the virological response to HAART.

Abstract
PURPOSE OF REVIEW This review presents recent findings on noninvasive alternatives for the diagnosis of fibrosis and cirrhosis in patients who are coinfected with HIV and hepatitis C virus (HCV). RECENT FINDINGS APRI, FIB-4, and Forns were accurate indices for the diagnosis of cirrhosis [area under the receiver operating characteristic curve (AUROC) >0.80] but not for the diagnosis of significant and advanced fibrosis (AUROC < 0.80). Diagnostic accuracy was affected by CD4 T-cell count and alanine aminotransferase levels. An artificial neural network to predict significant fibrosis was highly accurate (AUROC of 0.853), outperforming simple noninvasive indices. Derivations of the FibroMeter panel (FibroMeter HICV and FibroMeter HICV) achieved high diagnostic accuracy for significant fibrosis (AUROC of 0.823 and 0.833, respectively). Transient elastography had higher predictive accuracy than previously validated panels for diagnosis of advanced fibrosis (F ≥ 3) and cirrhosis (0.93 and 0.99, respectively). However, misclassification as F ≥ 3 was more common among patients with steatosis than among those without steatosis (25 versus 5%, P = 0.01). Moreover, transient elastography can predict clinically significant and severe portal hypertension in HIV/HCV-coinfected patients. SUMMARY Both biomarkers and transient elastography can accurately diagnose fibrosis and cirrhosis and are better at excluding than at predicting liver disease in HIV/HCV-coinfected patients.

Abstract
BACKGROUND The aim of this study was to describe changes in repeated liver stiffness (LS) measurements and to assess the determinants of increase in LS in HIV-HCV-coinfected patients. METHODS HIV-HCV-coinfected adults enrolled in the ANRS CO 13 HEPAVIH cohort, for whom two results of LS, evaluated over ≥24 months, were available. Patients with unreliable LS results were not included. LS was measured at baseline and every year thereafter. Determinants of LS increase were assessed using linear (primary outcome: last LS minus first LS value) and logistic (secondary outcome: ≥30% increase in the initial LS value) regression analyses. RESULTS A total of 313 patients (mean age 45 years, 67.4% male) were included. Overall, 93.9% were receiving antiretroviral treatment (ART). The mean baseline CD4(+) T-cell count was 471 cells/mm(3) and 72.2% of patients had undetectable plasma HIV RNA. The mean interval between the first and last LS measurements was 33.5 months. No significant difference was found between baseline and follow-up mean LS values (P=0.39). However, a decrease of ≥30% in LS was observed in 48 (15.3%) patients and an increase of ≥30% in 64 (20.5%) patients. In multivariate linear and logistic analyses, excessive alcohol intake (β coefficient 6.8; P=0.0006) and high HCV viral load (OR 1.7, 95% CI 1.1, 2.5; P=0.01) were independently associated with an increase in LS, whereas time on ART>114.5 months (OR 0.5, 95% CI 0.3, 0.9; P=0.03) and achievement of sustained virological response (OR 0.1, 95% CI 0.01, 0.9; P=0.04) were independently associated with no increase in LS. CONCLUSIONS Our findings show that long-term ART and achieving sustained virological response in HIV-HCV-coinfected patients are both significantly associated with lack of increase in LS over a 33-month period.
