RESUMEN

BACKGROUND: High-risk human papillomavirus (HR-HPV) is a known cause of cervical cancer (CC). Latvia has a high incidence of CC compared with the average incidence in the European Union. This study aims to fill the data gap on the HR-HPV burden in Latvia, providing information on its prevalence and associated factors. METHODS: The cross-sectional study was conducted from February 2021 to April 2022. Participants 25-70 years old visiting a general practitioner (general population) or those referred to a colposcopy clinic with changes in their cervical cytology (colposcopy population) collected vaginal self-sample and completed a paper-based questionnaire. Samples were analyzed with Cobas 6800 System (Roche) for HPV16, HPV18 and other HR-HPV (HPV31/33/35/39/45/51/52/56/58/59/66/68). Descriptive statistics for categorical variables were performed. The Chi-square test was used to determine for the statistical significance of differences in the proportions of the dependent variable between subgroups of the independent variable. Univariate and multivariate binary logistic regression were used to identify factors associated with positive HR-HPV status. Results were considered statistically significant at P < 0.05. RESULTS: A total of 1274 participants provided a valid sample. The prevalence of any HR-HPV infection was 66.8% in the colposcopy group and 11.0% in the general population. Factors associated with positive HR-HPV status were marital status single/divorced/widowed (vs. married/cohabiting) [adjusted OR (aOR) 2.6; P = 0.003], higher number of lifetime sex partners [aOR 5.1 (P < 0.001) and 4.0 (P = 0.001)] for six or more and three to five partners in the general population; in the colposcopy group, the statistical significance remained only for Latvian ethnicity (vs. other) (aOR 1.8; P = 0.008) and current smoking (vs. never) (aOR 1.9; P = 0.01). CONCLUSION: We documented a comparison to European Union HR-HPV infection burden in Latvia. Any HR-HPV positivity was significantly associated with sexual and other health behavior.

RESUMEN

OBJECTIVES: To describe age-specific and type-specific carcinogenic human papillomavirus (HPV) prevalence prior to large-scale effect of HPV vaccines in Estonia and to analyse the risk factors associated with carcinogenic HPV. DESIGN: Cross-sectional study using self-administered questionnaire and self-collected vaginal swabs for detection of HPV infection. SETTING: Estonian Biobank database. PARTICIPANTS: Stratified random sample of women aged 30-33, 57-60 and 67-70 years living in one of the three largest counties in Estonia. Of 3065 women approached, 1347 (43.9%) returned questionnaires and specimens for HPV DNA detection. OUTCOME MEASURES: HPV prevalence and fully adjusted ORs with 95% CIs for risk factors. RESULTS: HPV prevalence was highest among women aged 30-33 years (18.7%; 95% CI 15.8 to 21.9) followed by those aged 67-70 years (16.7%; 95% CI 12.4 to 22.0) and 57-60 years (10.2%; 95% CI 7.8 to 13.3). HPV16 and HPV56 were the most common among women aged 30-33 years (both 4.0%; 95% CI 2.7 to 5.9), and HPV68 was the most common among women aged 57-60 years (2.8%; 95% CI 1.5 to 4.7) and 67-70 years (6.4%; 95% CI 3.6 to 10.4). Vaccination with nonavalent vaccine would have halved the carcinogenic HPV prevalence among women aged 30-33 years. The odds of infection with carcinogenic HPV were higher among women with six or more sexual partners among younger (OR 2.99; 95% CI 1.54 to 5.81) and older (OR 3.80; 95% CI 1.25 to 11.55) women and lower (OR 0.35; 95% CI 0.17 to 0.72) among younger married women. CONCLUSIONS: This study demonstrated U-shaped age-specific genotype profile of carcinogenic HPV prevalence, indicating that public health providers should focus on developing exit strategies for the cervical cancer screening programme in Estonia with a possible extension of HPV testing beyond the current screening age of 65 years. Generalisability of the findings of this study may be affected by the low response rate.

RESUMEN

AIMS: To inform future Baltic States-specific policy analyses, we aimed to provide an overview of cervical cancer epidemiology and existing prevention efforts in Estonia, Latvia and Lithuania. METHODS: A structured desk review: we compiled and summarized data on current prevention strategies, population demography and epidemiology (high risk human papillomavirus (HPV) prevalence and cervical cancer incidence and mortality over time) for each Baltic State by reviewing published literature and official guidelines, performing registry-based analyses using secondary data and having discussions with experts in each country. RESULTS: We observed important similarities in the three Baltic States: high burden of the disease (high incidence and mortality of cervical cancer, changes in TNM (Classification of Malignant Tumors) stage distribution towards later stage at diagnosis), high burden of high-risk HPV in general population and suboptimal implementation of the preventive strategies as low screening and HPV vaccination coverage. CONCLUSIONS: Cervical cancer remains a substantial health problem in the region and the efforts in addressing barriers by implementing a four-step plan for elimination cervical cancer in Europe should be made. This goal is achievable through evidence-based steps in four key areas: vaccination, screening, treatment, and public awareness.

RESUMEN

ABSTRACT: The European Society of Gynaecological Oncology (ESGO), the International Society for the Study of Vulvovaginal Disease (ISSVD), the European College for the Study of Vulval Disease (ECSVD), and the European Federation for Colposcopy (EFC) developed consensus statements on pre-invasive vulvar lesions in order to improve the quality of care for patients with vaginal intraepithelial neoplasia (VaIN). The management of VaIN varies according to the grade of the lesion: VaIN 1 (low grade vaginal squamous intraepithelial lesions (SIL)) can be subjected to follow-up, while VaIN 2-3 (high-grade vaginal SIL) should be treated. Treatment needs individualization according to the patient's characteristics, disease extension and previous therapeutic procedures. Surgical excision is the mainstay of treatment and should be performed if invasion cannot be excluded. Total vaginectomy is used only in highly selected cases of extensive and persistent disease. Carbon dioxide (CO2) laser may be used as both an ablation method and an excisional one. Reported cure rates after laser excision and laser ablation are similar. Topical agents are useful for persistent, multifocal lesions or for patients who cannot undergo surgical treatment. Imiquimod was associated with the lowest recurrence rate, highest human papillomavirus (HPV) clearance, and can be considered the best topical approach. Trichloroacetic acid and 5-fluorouracil are historical options and should be discouraged. For VaIN after hysterectomy for cervical intraepithelial neoplasia (CIN) 3, laser vaporization and topical agents are not the best options, since they cannot reach epithelium buried in the vaginal scar. In these cases surgical options are preferable. Brachytherapy has a high overall success rate but due to late side effects should be reserved for poor surgical candidates, having multifocal disease, and with failed prior treatments. VaIN tends to recur and ensuring patient adherence to close follow-up visits is of the utmost importance. The first evaluation should be performed at 6 months with cytology and an HPV test during 2 years and annually thereafter. The implementation of vaccination against HPV infection is expected to contribute to the prevention of VaIN and thus cancer of the vagina. The effects of treatment can have an impact on quality of life and result in psychological and psychosexual issues which should be addressed. Patients with VaIN need clear and up-to-date information on a range of treatment options including risks and benefits, as well as the need for follow-up and the risk of recurrence.

RESUMEN

The three Baltic States (Estonia, Latvia, and Lithuania) are among the European Union countries with the highest incidence and mortality rates for cervical cancer. In order to tackle this public health challenge, there is an urgent need to implement more advanced and effective methods in cervical cancer prevention in Baltic countries. Nationwide cervical cancer screening programs in the Baltic States commenced in 2004-2009. While the organized screening programs in these countries differ in some relevant details (target age groups, screening interval), the underlying principles and problems, barriers are universal. However, the outcomes of present screening programs are unsatisfactory. In addition, universal screening programs are extremely costly. There is a potential need for more intelligent and personalized cervical cancer screening program. In 2019 the project "Towards elimination of cervical cancer: intelligent and personalized solutions for cancer screening" (2020-2023) was developed with the main objective - to develop improved and personalized cancer screening methods within a sustainable health care system. It is expected, that more sophisticated cervical cancer screening model will be implemented in Estonia, Latvia, and Lithuania, and will have a positive impact to epidemiology of cervical cancer and public health in general.

RESUMEN

ABSTRACT: The European Society of Gynaecological Oncology (ESGO), the International Society for the Study of Vulvovaginal Disease (ISSVD), the European College for the Study of Vulval Disease (ECSVD), and the European Federation for Colposcopy (EFC) developed consensus statements on pre-invasive vulvar lesions in order to improve the quality of care for patients with vulvar squamous intraepithelial neoplasia, vulvar Paget disease in situ, and melanoma in situ. For differentiated vulvar intraepithelial neoplasia (dVIN), an excisional procedure must always be adopted. For vulvar high-grade squamous intraepithelial lesion (VHSIL), both excisional procedures and ablative ones can be used. The latter can be considered for anatomy and function preservation and must be preceded by several representative biopsies to exclude malignancy. Medical treatment (imiquimod or cidofovir) can be considered for VHSIL. Recent studies favor an approach of using imiquimod in vulvar Paget's disease. Surgery must take into consideration that the extension of the disease is usually wider than what is evident in the skin. A 2 cm margin is usually considered necessary. A wide local excision with 1 cm free surgical margins is recommended for melanoma in situ. Following treatment of pre-invasive vulvar lesions, women should be seen on a regular basis for careful clinical assessment, including biopsy of any suspicious area. Follow-up should be modulated according to the risk of recurrence (type of lesion, patient age and immunological conditions, other associated lower genital tract lesions).

RESUMEN

The aim of this study is to analyse the association between vaginal microbiota and the histological finding of CIN. From July 2016 until June 2017, we included 110 consecutive patients with abnormal cervical cytology results referred for colposcopy to Riga East Clinical University Hospital Outpatient department in the study group. 118 women without cervical pathology were chosen as controls. Certified colposcopists performed interviews, gynaecological examinations and colposcopies for all participants. Material from the upper vaginal fornix was taken for pH measurement and wet-mount microscopy. Cervical biopsy samples were taken from all subjects in the study group and in case of a visual suspicion for CIN in the control group. Cervical pathology was more often associated with smoking (34.6% vs. 11.0%, p < 0.0001), low education level (47.2% vs. 25.5%, p = 0.001), increased vaginal pH (48.2% vs. 25.4%, p < 0.0001), abnormal vaginal microbiota (50% vs. 31.4%, p = 0.004) and moderate to severe aerobic vaginitis (msAV) (13.6% vs. 5.9%, p = 0.049) compared to controls. The most important independent risk factors associated with CIN2+ were smoking (OR 3.04 (95% CI 1.37-6.76), p = 0.006) and msAV (OR 3.18 (95% CI 1.13-8.93), p = 0.028). Bacterial vaginosis (BV) was found more often in CIN1 patients (8/31, 25.8%, p = 0.009) compared with healthy controls (8/118, 6.8%), or CIN2+ cases (8/79, 10.1%). In the current study msAV and smoking were the most significant factors in the development of CIN in HPV-infected women, especially high grade CIN. We suggest that AV changes are probably more important than the presence of BV in the pathogenesis of CIN and progression to cervix cancer and should not be ignored during the evaluation of the vaginal microbiota.

RESUMEN

OBJECTIVES: The aims of the study were to find out why some post-reproductive aged women did not participate in the organised cervical cancer screening programme in Latvia and to clarify factors that would motivate them to take part. METHODS: A cross-sectional study was carried out between January and July 2017 among female patients in three general practitioner (GP) practices. GP practice nurses used the Latvian national health service database to identify women aged 25-70 who had not participated in the organised programme for the last 3 years. Participants were asked to complete a specially developed questionnaire. The results were then compared between three age groups: 25-34, 35-49 and 50-70 years. RESULTS: Included in the study were 523 out of 992 women who had not attended screening; 41% were in the age group 50-70 years. Post-reproductive aged women statistically significantly more often did not take part in the programme because of lack of time (26.4%), too great a distance to the gynaecology screening clinic (10.4%), lengthy appointment waiting time (8.5%) and a belief that a smear test was unnecessary for them (8.5%); 32.1% of women in this age group indicated that if the cervical screen could be carried out by their GP it would facilitate their participation in the programme. CONCLUSION: Post-reproductive aged women in Latvia often do not attend cervical cancer screening. Analysis of personal and organisational barriers confirmed that the involvement of GPs would encourage older women to participate in the organised screening programme.

RESUMEN

INTRODUCTION: The incidence of cervical cancer (CC) in eastern European countries is high; however, uptake of available prevention strategies is suboptimal. We explored knowledge, behaviors, and attitudes toward CC prevention strategies in Latvian women. METHODS: A mixed-methods study of Latvian women, consisting of surveys and semi-structured interviews, was conducted in Riga, Latvia in September and October 2015. RESULTS: Altogether, 158 surveys were completed and 10 interviews were conducted. In total, 87% (n = 135) had previously had a smear test, and 67% (n = 105) correctly identified that cervical cytology was performed to identify precancerous changes. The practice of annual gynecological checkups was prevalent, and many believed it to be synonymous with cervical screening. Detailed knowledge of human papillomavirus (HPV) infection and the HPV vaccine was deficient, although 73% (n = 115) and 70% (n = 90), respectively, claimed to have heard of them. Negative attitudes existed regarding the HPV vaccine due to fear of potential side effects. On learning that HPV was transmitted through sexual contact, the notion of testing positive for HPV was met with shame and embarrassment. CONCLUSIONS: A small proportion of Latvian women are over-screened, whereas many women remain unscreened. The main contributing factor for this was their poor understanding of the roles that cervical screening and HPV vaccination play in preventing CC.

RESUMEN

INTRODUCTION: The disturbing, foul-smelling discharge of bacterial vaginosis (BV) is a nuisance to women. Treatment possibilities for BV are limited and only achieve complete cure in 65 to 85% of cases. In most women, the condition relapses within weeks to months after treatment. AREAS COVERED: In search of new therapeutic actions to cure, prevent or delay recurrences of BV, PubMed and web of science were searched for papers with i) decent study layout, ii) proper statistics, iii) comparison group (placebo or standard treatment) and iv) language English, French, Dutch or German. The following keywords were used: bacterial vaginosis and treatment or management or therapy or prophylaxis or prevention. Results were grouped in treatment categories and were discussed. EXPERT OPINION: Clindamycin and metronidazole are the standard drugs for BV. As other antibiotic and acidifying treatments are progressively being studied, like tinidazole, rifaximin, nitrofuran, dequalinium chloride, vitamin C and lactic acid, more options have become available for switching therapy, combining therapies and long-term prophylactic use to prevent recurrences. Further studies are needed. Also, adjuvant therapy with probiotics may have a significant role in improving efficacy and in preventing recurrences. However, it is unlikely that probiotics will replace antibiotherapy.

RESUMEN

PURPOSE: To evaluate the impact of vaginal ascorbic acid (vitamin C) as a treatment/maintenance regimen on increased vaginal pH and abnormal microflora on wet mounts in premenopausal women. METHODS: A randomized study of 140 asymptomatic, low-risk pregnant and non-pregnant premenopausal women with vaginal pH ≥ 4.5 and a variety of partly/completely disrupted Lactobacillus microflora patterns on wet mounts in five outpatient clinics was carried out. Participants were randomized to the intervention group [250 mg vitamin C tablets vaginally at bedtime once a day for 6 days (treatment phase), followed by a one tablet per week, for 12 weeks (maintenance phase)] or the control group (no treatment). Outcomes were evaluated 4 months after randomizing, i.e., 2-3 weeks after the last vitamin C tablet insertion. RESULTS: Normalization to normal flora was observed in 51.4 % of all ascorbic acid and in 24.3 % of control group patients (difference 27.1 %, 95 % CI 11.7-42.6, p < 0.05, ITT population). In the per protocol population, normalization was confirmed in 53.5 % of the intervention and 22.4 % of the control group (difference 31 %, 95 % CI 14.3-47.8, p < 0.05). Results of pregnant subgroup analysis showed better outcomes for the subgroup: difference of normalization rate between ascorbic acid and control group was 41.2 % (95 % CI 21.8-60.1, p < 0.05). Itching occurred in 19 %; 23 % of women reported irritation and 10 % stopped the treatment because of side effects. CONCLUSIONS: Vaginal ascorbic acid improves abnormal vaginal pH and microflora, especially in pregnant women, but is not well tolerated by all women.

RESUMEN

OBJECTIVES: The purpose of this study was to determine whether a low splenic artery pulsatility index (PI) and reduced flow through the left portal vein are involved in redistribution of fetal growth restriction. METHODS: Forty-two women with prenatally diagnosed intrauterine growth restriction of singleton fetuses were included. The next pregnant woman with an appropriately growing fetus, matched for gestational age, was selected as a control. Blood flow velocities were measured in the splenic artery and left portal vein. Obstetric and perinatal information was obtained from standardized medical records. RESULTS: The blood flow through the left portal vein was significantly reduced compared with the controls (P < .0001). Placental impairment in fetal growth restriction was clearly linked to a decreased splenic artery PI (P = .0004). In growth-restricted fetuses with reduced left portal vein flow and a splenic artery PI below the 5th percentile, perinatal mortality, a low 5-minute Apgar score, and neonatal metabolic acidosis were observed significantly more often (P = .04, .01, and .004; P = .03, .03, and .006, respectively). CONCLUSIONS: Reduced blood flow through the left portal vein and low resistance in the splenic artery can be found in growth-restricted fetuses with adverse neonatal outcomes.

RESUMEN

OBJECTIVE: To assess different bacterial and epidemiological factors associations with increased vaginal pH in the pregnant women population during the first trimester. DESIGN: A cross-sectional, observational study. SETTING: Three outpatient clinics in Riga. POPULATION: From July 2009 until January 2010, 139 unselected consecutive pregnant women at the first prenatal visit. METHODS: Pregnant women were submitted to an interview, vaginal examination and vaginal specimen collection for pH measurement and native microscopy. MAIN OUTCOME MEASURES: Vaginal pH ≥4.5 was considered as elevated. Abnormal bacterial microflora was classified according to Donders. RESULTS: Elevated vaginal pH was significantly associated with bacterial vaginosis (p < 0.001), aerobic vaginitis (p < 0.001) and mixed aerobic vaginitis and bacterial vaginosis flora (p < 0.001) and presence of sperm cells in the smears (p= 0.024). Most cases with sperm were associated with abnormal vaginal flora. Normal lactobacillary morphotypes were more often found in the pH ≤4.4 group (p < 0.001), while leptosomic and short types were found more frequently with increased pH. CONCLUSIONS: Elevated vaginal pH is associated with different types of abnormal vaginal flora and the presence of sperm cells.

RESUMEN

INTRODUCTION: Maternal risk factors may interfere with mechanisms regulating fetal growth. The aim of the present study was to determine which sociodemographic and reproductive risk factors may be related to fetal growth restriction (FGR), with a special focus on determinants possible for preventive intervention. MATERIALS AND METHODS: The study period is from May 2007 until December 2009. Data about lifestyle habits were collected by use of a detailed questionnaire in 65 women who attended Riga Maternity Hospital with the confirmed diagnosis of intrauterine FGR of a singleton fetus, and in 65 matched controls with normal pregnancies. RESULTS: Being unmarried (p = 0.04), having pregnancy-related blood pressure rise (p = 0.02), current (p = 0.01) and pre-pregnancy smoking (p = 0.01) and history of more than 3 pregnancy failures (p = 0.04) were more frequent in women with FGR than controls. Surprisingly, the finding of genital infection (STI) during pregnancy (p = 0.006) was also strongly associated with FGR. CONCLUSIONS: Obviously, several maternal risk factors play an important role in FGR. Besides refraining from smoking, screening and treating for STI may not only prevent preterm birth, but also FGR. Identifying such anticipating factors would likely have the potential impact if detected before conception, or as early as possible in gestation.

RESUMEN

BACKGROUND: To investigate the professional activity and perceptions of intrauterine contraception among Latvian obstetrician-gynecologists. METHODS: A questionnaire was completed by 122 Latvian obstetrician-gynecologists attending an annual meeting. Statistical analysis was done with the Epi-Info 2002 statistical package. RESULTS: Every day contraceptive consulting was done by 91.8% of physicians and 98.4% reported ever having inserted intrauterine contraception. The majority of doctors reported careful selection of intrauterine contraception candidates, including screening for sexually transmitted infections before insertion. Intrauterine contraception insertion was definitely excluded in women without a stable monogamous relationship only by 9.8%. A causal relationship between intrauterine contraception and pelvic inflammatory disease was believed by 52.5%. Many doctors sometimes prescribed prophylactic antibiotics before or immediately after intrauterine contraception insertion. However, antibiotics were never prescribed before intrauterine contraception insertion by 50.8%. Younger doctors had significantly more often themselves used combined oral contraceptives than had older doctors, whereas older doctors more often had been intrauterine contraception users. Of current and former intrauterine contraception users, 93.4% were satisfied with this contraceptive method. CONCLUSIONS: Latvian obstetrician-gynecologists have wide experience in contraception counseling of intrauterine contraception, but some gaps in the theoretical knowledge of doctors about intrauterine contraception were identified. We could not find any significant differences in attitudes to and personal experience with contraceptive methods between older and younger generations, nor were there any differences between genders of obstetrician-gynecologists.
