Opis:
Introduction. Human papillomavirus infections are frequent in on average 9% to 13% of the female population, and the risk of infection throughout life exceeds 50%. The HPV virus causes changes in the mucous membranes and the skin of the genital area in both women and men. Aim. This paper presents epidemiology, prophylaxis, diagnostics and treatment of HPV and cervical cancer infections. In addition, the knowledge of issues related to human papillomavirus infection among young women was assessed. Materials and methods. The diagnostic survey method was used to carry out the research. The research tool was a questionnaire of own authorship consisting of 41 questions. The research group consisted of 240 women. The research was carried out from June to September 2016 at the Chodźki Medical Center and the Luxmed facility in Lublin. Results. There is a relationship between the education of the respondents and their knowledge about the human papillomavirus infection. The studies did not show a significant relationship between the self-esteem of the studied women and whether they were vaccinated against the HPV virus (Chi-square = 0.362, p = 0.547). Conclusions. The general level of knowledge on issues related to human papillomavirus infection among young women is at the secondary level. A higher level of general knowledge was shown by women with better education, related to the medical and biological sciences. The self-assessment of the respondents coincides with the general knowledge, based on detailed questions, on issues related to HPV infection. Promoting knowledge about HPV infection is unsatisfactory

Opis:
The purpose of this study was to compare hybrid capture assay with PCRs using different primers for the L1, E6-E7 regions for the detection of human papillomavirus (HPV) genome. One hundred twenty-five cervical smears with normal (n = 42) and abnormal (n = 83) cytology were investigated. Those at high-risk for HPV were studied by hybridization antibody capture assay and PCR with the pU-1M/pU-2R primers. Target DNA from the HPV L1 region was amplified by SPF10 primer set and home-PCR with MY09/MY11 primers. The presence of HPV DNA in cervical smears was detected by SPF10 (in 72% of cases), MY09/MY11 (58%), hybrid capture (55%) and pU-1M/pU-2R (39%). Results obtained with the SPF10 and MY09/MY11 consensus primer sets as well as hybrid capture and pU-1M/pU-2R specific for high-risk types differed significantly (χ2, P < 0.0005). The correlation between assays with the use of SPF10 and MY09/MY11 was 86% and between hybrid capture and the pU-1M/pU2R technique - 78%. In 49% of samples HPV DNA was detected by the four methods, whereas in 12% only by the SPF10 primers. The most sensitive technique was found to be PCR with the use of SPF10 primers, while the most specific - the MY09/11 PCR method. It seems that home-PCR with MY09/MY11 primers could be applied in screening tests.

Opis:
Cervical carcinogenesis is a complex problem with papillomavirus widely accepted as a causative agent. Integration of a human papillomavirus (HPV) of the high-risk type into the host cell genome is one of the major contributing factors to cervical malignant transformation. In this study, the correlation of CMV, EBV, HSV-1, HSV-2, HHV-6 and HHV-7 infections with the physical status of the HPV genome in cervical cancer and precancerous cervical lesions was investigated in sixty HPV-16-positive women. Cervical secretion samples were submitted to DNA extraction and analyzed by PCR. HPV-16 DNA was confirmed in genotyping with the reverse hybridization line probe assay. Multiplex PCR with specific primers for the E2/E6 genes was used to assess the viral integration status of HPV-16. Our results show that CMV DNA was more frequently present in samples with mixed forms of HPV-16 than in the episomal form (P < 0.025). Such a correlation was also observed in the case of EBV (P < 0.005). The presence of CMV resulted in a six-fold (OR 6.069; 95% CI 1.91-19.22; P = 0.002), while EBV caused a seven-fold (OR 7.11; 95% CI 1.70-29.67; P = 0.007) increase in the risk of the integrated or mixed HPV-16 genome occurrence. Our data suggest that coinfection with herpesviruses, especially CMV and EBV, may be involved in the integration of the HPV-16 genome and may contribute to the development of cervical cancer.

Opis:
Human papillomavirus (HPV) is widely accepted as a causative agent of cervical cancer. The distribution and prevalence of HPV types depend on geographic region and demographic factors. The aim of this study was to investigate the relationship between the presence of various HPV types and the outcome of cytological examination. Cervical smears were obtained from 125 women from southern Poland: low grade squamous intraepithelial lesions (LSIL) - 44, high grade squamous intraepithelial lesions (HSIL) - 12, cervical carcinoma - 27 and 42 women without abnormality in cytology as a control group. DNA was extracted from the smears and broad-spectrum HPV DNA amplification and genotyping was performed with the SPF 10 primer set and reverse hybridisation line probe assay (INNO-LiPA HPV Genotyping, Innogenetics). HPV DNA was detected in approximately 72% cases, more frequently in women with squamous intraepithelial lesions and cervical carcinoma than in the control group (P < 0.0005). The most frequent type found was HPV 16 (37%), followed by HPV 51 (28%) and HPV 52 (17%). A single HPV type was detected in 51% positive cases, more frequently in cervical cancer specimens. Multiple HPV infection was dominant in women with LSIL and normal cytology. Prevalence of HPV 16 increased with the severity of cervical smear abnormality. For women HPV 16 positive, the relative risk (odds ratio) of the occurrence of HSIL and cervical cancer versus LSIL was 14.4 (95% CI, 3.0-69.2; P=0.001) and 49.4 (95% CI, 6.5-372.8; P < 0.001), respectively. Genotyping of HPV will allow better classification of women with cervical abnormalities into different risk groups and could be useful in therapy.

Opis:
The aim of this study was to analyse the correlation between a new multiplex qPCR assay and a reference qPCR assay for assessment of the human papillomavirus (HPV16) load and the viral genome status. The study was performed on 100 HPV16 positive samples containing premalignant lesions and carcinomas. HPV16 E2 and E6 gene loads were assessed by two PCR methods. The load of E2 and E6 was normalized to the cell number by qPCR targeting the RNase P open reading frame. The physical state of the viral genome was determined as a ratio of E2/E6 copies number per cell. Among 100 samples analysed, there were no statistically significant differences in the E2 and E6 viral load evaluated by multiplex qPCR and qPCR, the correlation coefficients were 0.98 and 0.97, respectively. There were 19% of samples with the integrated, 73% with mixed and 8% with episomal state of viral genome detected by multiplex qPCR and 17%, 79%, 4%, respectively, found by qPCR. Prevalence of integrated and episomal forms estimated by multiplex qPCR was higher than the one obtained by qPCR (Chi2, p < 0.0001), but in samples with premalignant and malignant diagnoses no significant differences were demonstrated regardless of the methods used. Sensitivity and specificity of multiplex qPCR were 93.7% and 100% as compared with qPCR, the positive predictive value was 100%. In summary, the multiplex qPCR assay in respect of HPV16 load and the frequency of viral genome status was shown to be a sensitive and specific reference method. Simultaneous estimation of E2 and E6 genes in one reaction tube reduces the cost of testing.

Opis:
Infections with human papillomavirus (HPV) are detected frequently. The occurrence of persistent infection with oncogenic HPV type associates with the development of cervical cancer. However, the part of HPV infections consist of the multiple viral types. The influence of HPV co-infections on the risk of the development of cervical cancer is not clear, but the occurrence of more than one viral type seems to increase the risk of advanced lesions of the uterine cervix. Additionally, possible interactions (both positive and negative) between particular HPV types in co-infections may influence the risk of the lesions progression. Although, the issue of HPV co-infections is not well known, the previous scientific reports make that the introduction of the molecular methods, allowing the identification not only single but also multiple HPV infections, in routine diagnostics seem to be important. Here, we present the PCR-RFLP and Real-Time PCR methods as the useful tools in the diagnostics of HPV infections.

Opis:
Introduction and objective. Biomarkers are measurable biological indicators of many disease states. Particularly noteworthy are short nucleotide sequences involved in the regulation of many cellular processes. Their level in body fluids constitutes an important biological marker of serious diseases, such as cancer or cardiovascular diseases. For example, different types of microRNA may be used as biomarker in virus-associated cancers. The aim of this article was to review the current knowledge on the miRNAs and their role in viral-related cancers (EBV and HPV). The article reviews information available in journals and on electronic databases. Brief description of the state of knowledge. A significant part of the world’s population hosts at least one of the oncoviruses, but only a small percentage of them undergo a cancerogenesis to which these infectious agents contribute. Interaction between the host cell and viral factors can lead to the origination of a microenvironment favourable to oncogenesis. Cancer arises as a result of dysregulation in many cellular processes, and particularly important are short RNA sequences which regulate the processes that can cause this disease. The varied expression of this ribonucleic acid contributes to many diseases and provides valuable information about health. Importantly, these molecules are differentially expressed in virally-induced cancer. Many publications have confirmed the relationship between the expression of specific types of miRNA and cancers associated with EBV and HPV. Conclusions. The use of miRNAs as biomarkers of neoplastic diseases associated with EBV and HPV infections may significantly contribute to the reduction of mortality caused by these viruses, and thanks to the development of modern technologies they are an attractive research object.

Introduction: Among the HPV infection risk factors one can list: age, early sexual activity, frequent change of sexual partners, multiparity, low socioeconomical status, coexistence of Chlamydia trachomatis, HSV type 2, HIV infections, vitamin deficiencies, smoking cigarettes, using hormonal contraceptives, immune system disorders and also pregnancy. The aim of the study is the assessment of human papillomavirus infection frequency in the course of pregnancy, particularly with attention to HPV type 16 infection. Material and methods: The study included 242 pregnant women who in the years 2004-2008 were treated in the Pathology of the Pregnancy Ward and Gynecologic-Obstetric Outpatient Clinic in the Voivodal Brodnowski Hospital. The patients included to the study had had cervical smear test performed by PCR method for HPV. Results: In the examined group of 242 pregnant patients human papillomavirus was isolated from 150 (62%) patients. Type 16 was statedin 87 (58%) patients. In case of normal pregnancy the presence of HPV virus was stated in 70.8% of cases (51 out of 72 women). In this group HPV type 16 comprised 61.6%. In pregnancies complicated with the symptoms of early termination the infections were stated in 99 out of 170 patients (58.2%). HPV type 16 infection was stated in 92.9% of cases. Conclusions: 1) In the analyzed material the frequency of human papillomavirus infection equaled 62%. Type 16 of virus caused 58% of these infections. 2) Regardless of the age of pregnancy and its course the percentage of cervix infections by HPV type 16 was quite significant and oscillated from 36% to 65%. 3) In patients who lost their pregnancies before 22 week of gestation, HPV type 16 was significantly more frequently isolated from miscarried tissues in comparison to its presence in cervical canal smear.
Wstęp: Wśród czynników ryzyka infekcji HPV wymienia się: wiek, wczesne rozpoczęcie współżycia płciowego, częstą zmianę partnerów seksualnych, wielorodność, niski status socjoekonomiczny, współistnienie zakażeń Chlamydia trachomatis, HSV typu 2., HIV, niedobory witaminowe, palenie papierosów, stosowanie antykoncepcji hormonalnej, zaburzenia odporności, a także ciążę. Celem pracy jest ocena częstości występowania zakażeń wirusem brodawczaka ludzkiego w przebiegu ciąży, ze szczególnym uwzględnieniem infekcji typem 16. HPV. Materiał i metody: Badaniem objęto 242 kobiety w ciąży, które w latach 2004-2008 były leczone na Oddziale Patologii Ciąży oraz w Poradni Ginekologiczno-Położniczej w Wojewódzkim Szpitalu Bródnowskim. Włączone do badania pacjentki miały wykonane badania wymazów z szyjki macicy metodą PCR w kierunku HPV. Wyniki: W badanej grupie 242 ciężarnych wirusa brodawczaka ludzkiego wyizolowano od 150 (62%) kobiet. Typ 16. rozpoznano u 87 (58%) pacjentek. W przypadku ciąży przebiegającej prawidłowo obecność wirusa stwierdzono w 70,8% przypadków (51 spośród 72 kobiet). W tej grupie HPV 16 stanowił 61,6%. W ciąży powikłanej wystąpieniem objawów przedwczesnego jej ukończenia infekcje rozpoznano u 99 spośród 170 pacjentek (58,2%). Zakażenie typem 16. stwierdzono w 92,2% przypadków. Wnioski: 1) W analizowanym materiale częstość zakażeń wirusem brodawczaka ludzkiego wynosiła 62%. Typ 16. wirusa wywołał 58% z tych infekcji. 2) Niezależnie od wielkości ciąży i jej przebiegu odsetek zakażeń szyjki macicy typem 16. HPV był dość znaczny i wahał się od 36% do 65%. 3) U pacjentek, które utraciły ciążę przed 22. tygodniem, znamiennie częściej w poronionych tkankach izolowano typ 16. wirusa HPV w porównaniu z jego obecnością w wymazach z kanału szyjki macicy.

Opis:
Human papillomavirus (HPV) belongs to the family of DNA viruses. Infection by HPV is associated with the development of benign or malignant lesions within mucosal membrane and skin of the genitals, anus, head and neck. Presence of the virus, particularly of the highly oncogenic variants in epithelial cells of uterine cervix directly influences the development of cervical cancer. In a considerable proportion of cases, HPV infections are asymptomatic and this is probably associated with lack of proliferation phase of viral life cycle, or may be transient, which greatly complicates early detection of the virus. Diagnostic techniques enabling diagnosis of HPV infection include: cytological exam (PAP smear), colposcopy, histological study, as well as increasingly sophisticated molecular techniques, enabling detection of viral DNA when other indices of infection are lacking. These techniques include Southern Blot, Dot Blot, in situ hybridization, polymerase chain reaction (PCR) and Hybrid Capture System I and II (HCI, HCII). Increasingly often authors refer to tests based on isolation of viral mRNA (PreTect HPV-Proofer test). These techniques detect integrated form of HPV, the so-called episomal form of the virus. In general opinion, the presence of HPV in this form is directly associated with progression of lesions developing as a result of this infection. While the PreTect HPV-Proofer test detects a smaller number of cases of HPV infection, its use enables selection of patients most at risk of developing cervical cancer.
Wirus brodawczaka ludzkiego (HPV) należy do grupy DNA wirusów. Infekcje wirusem brodawczaka ludzkiego wiążą się z występowaniem łagodnych lub złośliwych zmian w obrębie błon śluzowych i skóry narządów płciowych, odbytu, jak również głowy i szyi. Obecność wirusa, szczególnie typów wysokoonkogennych, w komórkach nabłonka szyjki macicy bezpośrednio wpływa na rozwój raka szyjki macicy. Zakażenia HPV w dużym odsetku przebiegają bezobjawowo i jest to najprawdopodobniej związane z niewystąpieniem fazy proliferacyjnej cyklu życiowego wirusa, a także mają charakter przejściowy, co znacznie utrudnia wczesną identyfikację wirusa. Wśród metod diagnostycznych umożliwiających rozpoznanie zakażenia wymienia się badanie cytologiczne, kolposkopię, badanie histologiczne, a także coraz doskonalsze metody molekularne, które pozwalają wykryć wirusowe DNA w przypadkach braku innych wykładników zakażenia. Do metod tych zalicza się: Southern Blot, Dot Blot, hybrydyzacje in situ, polymerase chain reaction (PCR), Hybrid Capture System I i II (HCI, HCII). Coraz częściej wspomina się o testach opartych na izolacji mRNA wirusa HPV (PreTect HPV-Proofer test). Metody te wykrywają zintegrowaną formę HPV, tzw. formę episomalną wirusa. Uważa się, że obecność wirusa HPV w tej postaci jest bezpośrednio związana z progresją zmian powstałych na podłożu tego zakażenia. Co prawda przy pomocy testu PreTect HPV-Proofer wykrywa się mniejszą liczbę zakażeń HPV, ale stosując go, można wyodrębnić grupę pacjentek najbardziej narażonych na raka szyjki macicy.
