perinatal transmission of hpv

This child was born by cesarian section without early rupture of membranes and by restricted fetal growth. Oral manifestations of human papillomavirus infections. All the HPV-DNA positive children (22.4%, n = 11/49) at birth and at the end first month of life (6.1%, n = 3/49) became HPV-DNA negative at the age of 6 months. Careers. 10.1056/NEJMsb022734, Article  Perinatal Transmission (Via the Birth Canal) More commonly, a baby may acquire HPV from a mother as it passes through the birth canal during delivery. 2019 Nov 4;19(1):930. doi: 10.1186/s12879-019-4503-4. In the twelfth month all (100%, n = 49/49) the children studied were HPV-DNA negative. 10.1016/S0002-9378(97)70399-5.

Rombaldi, R.L., Serafini, E.P., Mandelli, J. et al. Gynecol Oncol 1994, 54: 152-158. RLR, EPS, JM, KPL and EZ participated in the sequence alignment and drafted the manuscript. Virol J. Perinatal transmission was considered when concordance was found in type-specific HPV between mother/newborn or mother/child. Whether acquisition of human papillomavirus during the perinatal period predisposes to an increased risk of cervical intraepithelial neoplasia among female infants in later life remains to be established. High prevalence of high risk human papillomavirus-capsid antibodies in human immunodeficiency virus-seropositive men: a serological study. 2012 May;160(5):837-43. doi: 10.1016/j.jpeds.2011.10.027. All infants tested at six months were HPV negative. National Library of Medicine Gajewska M, Marianowski L, Wielgos M, Malejczyk M, Majewski S. Neuro Endocrinol Lett. Aust N Z J Obstet Gynaecol 1993, 33: 30-32. HPV transmission via contact with contaminated objects or surfaces is possible [43]. Eleven newborns (22.4%, n = 11/49) were HPV-DNA positive. Methods Three hundred one pregnant women were selected: vaginal delivery (n = 160) or cesarean delivery (n = 141). doi: 10.1093/jnci/85.12.958. As to sensitivity and performance with clinical samples, the novel NMPCR assay is a potentially useful tool for HPV-DNA detection in epidemiologic and clinical follow-up studies, especially when accurate HPV typing and the detection of multiple HPV infections are required. In three cases no concordance of the type specific HPV between mother/NB were observed. Perinatal route of transmission of human papillomavirus (HPV) has been demonstrated in several small studies. It is becoming increasingly clear that HPV-DNA can be acquired by non-sexual routes, and that one of these would be mother-child transmission during the perinatal period [5-8]. Four μg of the molecular DNA of the DNA φ X 174RF HaeIII molecular weight marker were used. HPV genotypes 6 and 11 are the primary cause of condylomata acuminata, although in children non-genital genotypes are also found in a proportion, with the mode of transmission being either perinatal, horizontal, or sexual. HPV infection has been identified in 1% to 20%[27, 29] of babies newly born to pregnant women who do not show any evidence of cervical HPV infection, and in 5% to 72%[30, 31] in newborns of women with a diagnosis of the viral infection during pregnancy. The authors declare that they have no competing interests. Part of -, Munoz N. Human papillomavirus and cancer: the epidemiological evidence.

RLR, EPS, JM, KPL and EZ have given final approval of the version to be published. Authors have described the presence of HPV-DNA in amniotic liquid[13], in cord blood[14], in fetuses with malformations[7] and in specimens from first trimester spontaneous abortions[34]. The following sampling methods were used: (1) in the pregnant woman, when was recruited, in cervix and clinical lesions of the vagina, vulva and perineal region; (2) in the newborn, (a) buccal, axillary and inguinal regions; (b) nasopharyngeal aspirate, and (c) cord blood; (3) in the children, buccal was repeated in the 4th week and 6th and 12th month of life. Int J STD AIDS 2007, 18: 839-841. J Natl Cancer Inst. In 8 cases (16.3%, n = 8/49) there was type specific HPV concordance between mother/newborn samples. Proc Assoc Am Physicians. Statistical analyses were performed with the SPSS computer software package (version 12.0 for Windows). In this case, in epidemiological maternal history, it was observed that the pregnant joined the research for high-grade squamous intraepithelial lesions, with negative result for HPV-DNA. Delivery via cesarean section does not eliminate the possibility of vertical transmission of HPV; there are reports of congenital condyloma after cesarean section without premature rupture of membranes[43]. In the brush samples, DNA was extracted using 600 μl of NaOH 50 mM, stirred in a vortex for 5–10 seconds and later incubated at 95°C for 5 minutes. Hernandez-Giron C, Smith JS, Lorincz A, Arreola Chaidez E, Lazcano E, Hernandez-Avila M, Salmeron J: [The prevalence of high-risk HPV infection in pregnant women from Morelos, Mexico]. Mazzatenta C, Fimiani M, Rubegni P, Andreassi L, Buffi P, Messina C: Vertical transmission of human papillomavirus in cytologically normal women. There was agreement of the type specific HPV between the mother/NB (HPV type 6/11). The types of HPV-DNA detected were: 6/11 (53.3%), 16 and 52 (13.3% each). Eleven newborns (22.4%, n = 11/49) were HPV-DNA positive. Results: A total of 291 Persistent human papillomavirus infection was demonstrated at six weeks of age. Neuro Endocrinol Lett 2006, 27: 529-534. 2005 Dec;26(6):766-70. Studying the buccal samples from infant, obtained in the 6th month of life, it was observed that one child (2%, n = 1/49) had become HPV-DNA+ between the 1st and 6th month of life (Table 3). Finally, research indicates that nonsexual modes of HPV transmission include perinatal transmission from an infected mother [53]. Later the samples in polyacrylamide gel were stained with silver nitrate and the fragments obtained compared to the prototypes described by Bernard et al. At the end of the first month of life three children (6.1%, n = 3/49) became HPV-DNA positive, while two remained positive from birth. Viruses. At five weeks after birth all the oral samples from the 19 infants born from HPV positive mothers were negative. We assessed the presence of the HPV types 16 and 18 DNA sequences in … Rarely, HPV types 6 and 11 can cause respiratory papillomatosis in infants and children, although the route of transmission (i.e., transplacental, perinatal, or postnatal) is not completely understood. The frequency of perinatal vertical transmission, from HPV positive mothers to their neonates, was 31.6% (6/19). Article  Differences in the means of continuous variables between the groups were analyzed by using nonparametric tests. Between April 2005 and December 2008, a cross-sectional, prospective study was performed on pregnant women with a prior history of HPV infection, or who had abnormal Papanicolaou smear or genital warts, due to the high probability that they could have HPV infection. Polymerase chain reaction was … https://obgyn.onlinelibrary.wiley.com/doi/full/10.1111/jog.13248 Eleven newborns (22.4%, n = 11/49) were HPV-DNA positive. Current concepts on human papillomavirus infections in children. The distal extremity of the catheter (about 4 cm long) was cut and placed in TE solution (Tris HCl, pH 7.5 – 10 mM; EDTA, 1 mM), keeping it frozen at -20°C, until DNA was extracted.
