Molecular Detection of HPV, EBV, HSV-1, HCMV, and H. pylori Pathogens: An Evaluation among Polish Children with Molar Incisor Hypomineralization (MIH). Pathogens 2024; 13:345. [PMID: 38668300 PMCID: PMC11054144 DOI: 10.3390/pathogens13040345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 04/17/2024] [Accepted: 04/18/2024] [Indexed: 04/29/2024] Open
Abstract
Molar incisor hypomineralization (MIH) is a congenital disorder of the enamel tissue, characterized by a quantitative deficiency. In childhood, infections such as EBV, HSV-1, HCMV, or H. pylori may occur and cause various diseases. This study aimed to investigate the prevalence of HPV, EBV, HSV-1, HCMV, and H. pylori infections in two groups of children: children with molar incisor hypomineralization (MIH) and a control group, using molecular methods. The study group included 47 children aged between 6-13 years who had been diagnosed with MIH. The control group consisted of 42 children. The study found that, in the MIH group, the prevalence of HPV-16 was 6.38%, HPV-18 was 4.26%, EBV was 31.91%, HSV-1 was 4.26%, HCMV was 4.26%, and H. pylori was 12.77%. There were no significant differences in the prevalence of any of tested pathogens between the study and the control group (p > 0.05). However, the study found a higher prevalence of EBV infection in children who had smallpox/pneumonia by the age of 3 years. Ten children were found to have at least two pathogens present. Moreover, both groups had a high prevalence and activity of EBV. These findings provide new insights into the carriage of pathogens among children with MIH, providing new information for parents, scientists, and healthcare professionals.

Biologically active polyphenolic compounds from Lespedeza bicolor. Fitoterapia 2022; 157:105121. [PMID: 34990769 DOI: 10.1016/j.fitote.2021.105121] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 12/27/2021] [Accepted: 12/28/2021] [Indexed: 11/20/2022]
Abstract
We investigated the ability of six prenylated prerocarpans, stilbenoid, and a new dimeric flavonoid, lespebicolin B, from stem bark as well as two 3-O-rutinosides and a mixture of 3-O-β-D-glucosides of quercetin and kaempferol from flowers of Lespedeza bicolor to inhibit HSV-1 replication in Vero cells. Pretreatment of HSV-1 with polyphenolic compounds (direct virucidal effect) showed that pterocarpans lespedezol A2 (1), (6aR,11aR)-6a,11a-dihydrolespedezol A2 (2), (6aR,11aR)-2-isoprenyldihydrolespedezol A2 (4), and (6aR,11aR,3'R)-dihydrolespedezol A3 (5) significantly inhibited viral replication, with a selective index (SI) ≥10. Compound 4 possessed the lowest 50% - inhibiting concentration (IC50) and the highest SI values (2.6 μM and 27.9, respectively) in this test. (6aR,11aR)-2-Isoprenyldihydrolespedezol A2 (4) also had a moderate effect under simultaneous treatment of Vero cells with the tested compound and virus (IC50 and SI values were 5.86 μM and 12.4, respectively). 3-O-rutinosides of quercetin and kaempferol and a mixture of 3-O-β-D-glucosides of quercetin and kaempferol (10 and 12) also showed significant virucidal activity, with SI values of 12.5, 14.6, and 98.2, respectively, and IC50 values of 8.6, 12.2, and 3.6, respectively. We also performed a quantitative structure-activity relationship (QSAR) analysis of data on the virucidal activity of polyphenolics with 4 < pIC50 < 6. It was found that the virucidal activity of these compounds depended on both the structure of the aromatic part and the conformation of geranyl and isoprenyl side chains of their molecules. These findings are correlated with the largest value of the principal moment of inertia (pmi) descriptor describing the geometry of molecules.

Abstract
The study showed a high prevalence of markers of herpesvirus infections among mothers — from 71% to 98% of HSV, EBV and CMV infections and from 29% to 58% of HHV-6 infection. HSV remains the most common etiological agent of intrauterine infections among herpesviruses — markers of active infection caused by this virus were found in 28.3% samples. The difficulty of determining the source of infection in the absence of data in the early stages of pregnancy is presented on 4 out of 10 cases of active HHV-6 infection. Markers of active pneumocystic infection were detected only in mothers: in the group with children under the age of 21 days — in 21—27% of cases, with children aged 22 to 28 days — in 15—21%. In addition to non-specific multiple organ failure during intrauterine infections (26.3%), only one organ system was observed: hypoxic-hemorrhagic lesions of the central nervous system were diagnosed more often — 17%, as well as meningitis/encephalitis, or hepatitis, or pneumonia, or disorders of hematopoiesis, or rash. In 17.5% of children from the comparison group, i.e. without any clinical manifestations of intrauterine infections, markers of active herpes virus infections were detected.

Abstract
Quinones are secondary metabolites of higher plants associated with many biological activities, including antiviral effects and cytotoxicity. In this study, the anti-herpetic and anti-dengue evaluation of 27 terpenyl-1,4-naphthoquinone (NQ), 1,4-anthraquinone (AQ) and heterocycle-fused quinone (HetQ) derivatives was done in vitro against Human Herpesvirus (HHV) type 1 and 2, and Dengue virus serotype 2 (DENV-2). The cytotoxicity on HeLa and Jurkat tumor cell lines was also tested. Using plaque forming unit assays, cell viability assays and molecular docking, we found that NQ 4 was the best antiviral compound, while AQ 11 was the most active and selective molecule on the tested tumor cells. NQ 4 showed a fair antiviral activity against Herpesviruses (EC50: <0.4 µg/mL, <1.28 µM) and DENV-2 (1.6 µg/mL, 5.1 µM) on pre-infective stages. Additionally, NQ 4 disrupted the viral attachment of HHV-1 to Vero cells (EC50: 0.12 µg/mL, 0.38 µM) with a very high selectivity index (SI = 1728). The in silico analysis predicted that this quinone could bind to the prefusion form of the E glycoprotein of DENV-2. These findings demonstrate that NQ 4 is a potent and highly selective antiviral compound, while suggesting its ability to prevent Herpes and Dengue infections. Additionally, AQ 11 can be considered of interest as a leader for the design of new anticancer agents.

Abstract
Data from 215 pregnant women exposed to varicella and 276 with varicella observed at the Tuscany Reference Center for Infectious Diseases in Pregnancy, Florence, Italy, in the period 1997-2016 were retrospectively collected. The risk of developing varicella was lower in exposed women who received varicella zoster immunoglobulin compared with those who did not receive it [42% (21 of 50) vs 72% (13 of 18); p = 0.0263]. Typical congenital varicella syndrome was observed in 1.56% of fetuses/neonates born from pregnant women with varicella.
