The Impact

The impact of human papillomavirus (HPV) infection on pregnancy is a major problem of medicine. The transmission of the virus from mother to fetus is a process yet unresolved. The immune response and changed hormonal status of pregnant women might facilitate infection. A research on the prevalence of HPV infection was conducted at the Clinic of Obstetrics, Medical University of Lublin (Poland). The studied group included 152 randomly selected women. The material was tested for the presence of HPV DNA by means of polymerase chain reaction (PCR). The aim of the research was to assess the relation between HPV infections detected in the buccal smears of the neonates and the incidence of such infections in the cervical/buccal smears of their mothers. In the group of 152 infants HPV was found in 16 (10.53%). Among the cervical/buccal smears, HPV was isolated, respectively, in 24 (15.79%) and in 19 (12.5%) pregnant women. Statistically significant differences in the prevalence of HPV swabs from the newborns and the cervical/buccal smears of their mothers were found (p< 0.001). The identification of mothers in whose buccal smears HPV was detected can help develop a group of children who run a relatively significant risk of being infected.

Objective Human papillomavirus (HPV) has been identified as the principal etiologic agent for cervical cancer and its precursors. Different HPV types have been associated with different oncogenic potential. The purpose of this study was to evaluate the relationship between specific HPV type infection and expression pattern of the ras family oncogenes in different grades of HPV-associated human cervical neoplasia. Methods HPV typing was performed using polymerase chain reaction (PCR) in 31 HPV-positive human cervical specimens from patients with squamous intraepithelial lesions (SIL) or squamous cervical carcinoma (SCC). The mRNA expression levels of H-, K- and N-ras oncogenes were examined using the reverse transcriptase polymerase chain reaction (RT-PCR) technique. Statistical analyses were performed using SPSS software. Results Among patients with SCC, H-, K- and N-ras expression levels were higher in HPV 16/18-associated cases compared to HPV 16/18-unassociated samples (p=0.003, p=0.004 and p=0.0001, respectively). The expression levels for H-, K-and N-ras were significantly higher in SCC patients with multiple HPV infection compared with SCC patients with single HPV infection (p=0.009, p=0.01 and p=0.021, respectively). Among patients with SIL, no statistically significant relationship was found between ras expression and HPV status. Conclusion Our findings indicate the possible role of ras signaling interaction with “high-risk” HPV 16/18 and multiple HPV infection in cervical cancer development.

Inverted Papillomas

Paraffin-embedded tissues of 42 sinonasal inverted papillomas were subjected to polymerase chain reaction using type-specific primers pairs of HPV 6, 11, 16, 18, and 33. Two cases of HPV 11 and one of HPV 6 were amplified in 36 samples of benign inverted papilloma, and two cases of HPV 16 were amplified in five samples of inverted papilloma with co-existing squamous cell carcinoma. Inverted papillomas recurred in 1 (16%) of 6 cases exhibiting dysplasia, and in 3 (10%) of 30 cases not exhibiting dysplasia. Inverted papillomas also recurred in 2 (66%) of 3 cases positive for HPV, and in 2 (6%) of 33 cases negative for HPV. These results suggest that HPV may be involved in the pathogenesis of inverted papillomas, may cause malignant transformation of inverted papillomas, and that there may be an apparent relationship between HPV infection and the recurrence of sinonasal inverted papillomas.

The aim of this study was to evaluate the accuracy of human papillomavirus (HPV) genotyping by a polymerase chain reaction (PCR)-based genechip method and to determine the prognostic value of HPV genotype in bulky stage IB or IIA cervical carcinoma treated with neoadjuvant chemotherapy (NAC) and radical surgery. A total of 149 patients had adequate tissue for the study. The SPF1/GP6+ primers were used to amplify a 184 bp fragment. The amplimers were submitted for direct sequencing and hybridization with a genechip using revert-blot detection of 39 types of HPV DNA in a single reaction. Two runs of PCR with respective hybridization were performed for each tumor. The complete concordance of HPV genotyping was 80.5% (120/149) of the paired genechip results. The kappa coefficient was 0.634 (P < 0.0001). HPV DNA sequences were detected in 100% of the specimens, among which 67.8% harbored single type and 32.2% contained multiple types. HPV-16 was detected in 98.7%, HPV-18 in 22.8%, HPV-31 in 0.7%, HPV-45 in 1.3%, HPV-52 in 2.0%, HPV-58 in 6.7%, HPV-59 in 4.7%, and HPV-67 in 0.7%. In multivariate analyses, the HPV genotype [HPV-18 or HPV-16 and HPV-18 only versus all others: relative risk (RR), 2.33; 95% CI, 1.17–4.64; P = 0.016] and pre-NAC tumor size (>5 versus ≤5 cm: RR, 2.25; 95% CI, 1.13–4.48; P = 0.021) were significantly related to overall survival. This PCR-based genechip method is sensitive and reproducible for HPV genotyping. The association of HPV-18 or HPV-16 and HPV-18 with poor outcome in cervical carcinoma treated with NAC plus radical surgery is confirmed.

Loop Electrosurgical Excision Procedure

We aimed to investigate whether postconization human papillomavirus (HPV) DNA testing can predict treatment failure and improve the accuracy of conventional follow-up in women with high-grade cervical intraepithelial neoplasia (CIN). Between March 2001 and October 2005, 120 patients with confirmed CIN 2 or 3 were treated with loop electrosurgical excision procedure (LEEP) and were enrolled. Six patients were lost to the follow-up. Postconization follow-up was performed at every 3–6 months during the first year and then annually. Specimens were tested for the presence of HPV, using the Hybrid Capture 2 (Digene Co, Gaithersburg, MD) and HPV DNA chip (Mygene Co, Seoul, Korea) test. Persistent HPV infection was defined as persistently (two times or more) positive HPV tests with the same HPV subtype(s) at initial diagnosis. Twenty-two (19.3%) patients showed treatment failure after conization. The only significant risk factor for redevelopment of CIN after conization was persistence of the same HPV subtype (P< 0.0001). And women with recurrent or residual CIN had higher HPV load during the 6-month follow-up postconization. In conclusion, the persistence of the same HPV subtype after LEEP conization was an important predictor of treatment failure. The follow-up protocol after conization of CIN should include both cervical cytology and HPV test, and HPV DNA chip test is needed to detect a persistent HPV infection.

ObjectivesHuman papillomavirus (HPV) testing is an important part of cervical cancer screening and management of women with atypical screening results. This study was conducted to evaluate the analytical and clinical performance of the Abbott RealTime High-Risk HPV assay (RealTime) in a referral population, in comparison to the Qiagen Hybrid Capture 2 High-Risk HPV DNA Test (hc2).MethodsRealTime is a new polymerase chain reaction assay that detects 14 high-risk HPV genotypes with simultaneous differentiation between HPV 16 and HPV 18. Five hundred forty-five routine cervical smear samples (ThinPrep) from women who were referred to 2 German colposcopy clinics were included in the study. All samples were tested with both assays for the detection of high-risk HPV DNA. Specimens with repeatedly discordant results were genotyped by Linear Array (Roche) and in-house polymerase chain reaction assays.ResultsBoth assays showed excellent overall agreement (92.8%; κ = 0.86) on 545 samples. Analytical sensitivity of RealTime was comparable to that of hc2 (97.6% vs 95.1%,P= 0.189), whereas RealTime demonstrated significantly higher analytical specificity compared with hc2 (100% vs 93.1%,P< 0.0001). RealTime showed no cross-reactivity with untargeted HPV genotypes in this study. The clinical performance of the assays was evaluated based on histology results available from 319 women (90 nonpathological, 73 cervical intraepithelial neoplasia [CIN] 1, 75 CIN 2, 74 CIN 3, and 7 invasive cancers). High-risk HPV detection rates observed in women with CIN 1, CIN 2+, and CIN 3+ diagnosis, respectively, were comparable for both assays: 47.9%, 92.3%, and 97.5% (RealTime) and 47.9%, 92.3%, and 93.8% (hc2). Detection of HPV 16/18 with RealTime was highly correlated with severity of dysplasia: less than CIN 2, 30.5%; CIN 2+, 59.0%; CIN 3+, 71.6%.ConclusionsThese results support the use of RealTime for routine detection of HPV infections in a referral population.

The Impact

Covid 19 is an infectious disease caused by coronavirus. This virus first appeared in Wuhan China. The manifestations of this disease vary in each person, ranging from no symptoms, mild symptoms to severe symptoms that can even cause death. Mothers who are confirmed to have Covid 19 can experience various symptoms such as those who are not pregnant. This research method is a descriptive study to describe the condition of pregnancy with the COVID 19 virus infection which is taken from various previous research sources. Result: Symptoms that appear include cough, fever and sore throat. However, in pregnant women, the placenta serves as a barrier that can prevent transmission of Covid 19 from mother to fetus. Pregnant women with comorbidities who are confirmed positive for Covid 19 increase the risk of illness and increase the need for ICU. The diagnosis of Covid 19 can be confirmed in various ways, but the gold standard that can be used as a reference for diagnosing Covid 19 is the polymerase chain reaction (PCR) culture test. The impact of pregnancy confirmed by Covid 19 is maternal mortality, preterm delivery and fetal growth disorders and fetal death.
