Objectives: Atypical squamous cells of undetermined significance (ASC-US) represent a diagnostic challenge during cervical cytology. This study aimed to review and identify high-risk human papillomavirus (HR-HPV) genotypes among previously diagnosed ASC-US cases in Kuwait. Methods: This retrospective study analysed 180 cases diagnosed as ASC-US between June 2017 and May 2018 at the Mubarak Al-Kabeer Hospital, Kuwait. Cervical specimens were assayed to determine the presence of HR-HPV DNA; subsequently, positive cases underwent genotyping and were categorised into three groups (HPV 16, HPV 18/45 and other HR-HPV types). Results: In total, ASC-US was confirmed in only 105 cases (58.3%), with the remaining cases reclassified as negative for intraepithelial lesions or malignancy (NILM; 32.2%) and epithelial cell abnormalities (ECA; 9.4%). Of these, HRHPV DNA was present in 20 ASC-US (19%), one NILM (1.7%) and six ECA (35.3%) cases. There were 62 Kuwaiti and 43 non-Kuwaiti women with confirmed ASC-US; of these, three (4.8%), six (9.7%) and four (6.5%) Kuwaitis and one (2.3%), one (2.3%) and five (11.6%) non-Kuwaitis had HPV 16, both HPV 16 and 18/45 and other HRHPV genotypes, respectively. Of those with HR-HPV DNA, the NILM case had the HPV 18/45 genotype, while the six ECA cases had the HPV 16 (n = 1), both HPV 16 and 18/45 (n = 1) and other HR-HPV (n = 4) genotypes. Conclusion: Overall, HR-HPV DNA was present in 19% of ASC-US cases compared to 1.7% of NILM cases initially misdiagnosed as ASC-US. Re-review of cervical cytology diagnoses may reduce unnecessary costs associated with HR-HPV genotyping.

Recently, there has been a steady growth of cervical cancer all over the world, especially in Russia. Patients with cervical cancer have become much younger. At the same time, the human papillomavirus is not only the main factor in the neoplastic process, but it is also one of the most common sexually transmitted infections in the world. The aim of the paper is to assess the prevalence and characteristics of human papillomavirus genotypes in patients with cervical intraepithelial neoplasia. Materials and Methods. During the periodic screening we examined 213 women of a reproductive age with HPV infection. All patients underwent liquid-based cytology and human papillomavirus genotyping by polymerase chain reaction. Results. We revealed that the prevalence of cervical intraepithelial neoplasia among women with papillomavirus infection was 80.3 % (n=171). According to human papillomavirus genotyping, HPV 16 (38 %) and HPV 33 (32 %) prevailed. We also observed positive high correlation between high-grade squamous intraepithelial lesions (HSIL) and HPV 18 (r=+0.759, p=0.001), a negative mean correlation between HPV 45 and low-grade squamous intraepithelial lesions (LSIL) (r=-0.643, p=0.002). A cohort of patients with severe intraepithelial cervical lesions demonstrated high viral load rates. Conclusion. According to the results obtained, we established the dominance of HPV 16 and HPV 33 genotypes in cervical intraepithelial neoplasia. There were significant differences between HSIL and LSIL patients with HPV 18 and HPV 45. There was also a correlation between an increase in the viral load with the severity of the pathological process. Keywords: human papillomavirus, intraepithelial cervical neoplasms, cervical cancer. В последние годы в мире, особенно в России, наблюдается неуклонный рост и «омолаживание» рака шейки матки. При этом вирус папилломы человека является не только основным фактором прогрессирования неопластического процесса, но и одной из наиболее распространенных инфекций, предаваемых половым путем, в мире. Цель. Оценить распространенность и характеристику генотипов папилломавирусной инфекции у пациенток с цервикальными интраэпителиальными неоплазиями. Материалы и методы. Проведено обследование 213 пациенток репродуктивного возраста с ВПЧ-инфекцией, пришедших на профилактический осмотр. Всем женщинам было выполнено цитологическое исследование жидкостным методом и генотипирование вируса папилломы человека методом полимеразной цепной реакции. Результаты. Распространенность цервикальных интраэпителиальных неоплазий среди женщин с папилломавирусной инфекцией составила 80,3 % (171 пациентка). Согласно данным генотипирования вируса папилломы человека превалировал 16-й (38 %) и 33-й типы (32 %). Выявлена положительная высокая корреляционная связь между цервикальными неоплазиями высокой степени онкогенного риска (HSIL) и 18-м типом ВПЧ-инфекции (r=+0,759 при р=0,001), отрицательная средняя корреляционная связь 45-го типа ВПЧ с низкой степенью онкогенного риска (LSIL) (r=-0,643 при р=0,002). Продемонстрированы высокие показатели вирусной нагрузки в когорте пациенток с тяжелыми внутриэпителиальными цервикальными поражениями. Выводы. По результатам полученных данных установлено доминирование 16-го и 33-го генотипов ВПЧ при цервикальных интраэпителиальных неоплазиях с наличием значимых различий между пациентами с HSIL и LSIL в отношении 18-го и 45-го типов, а также связь роста уровня вирусной нагрузки с увеличением степени тяжести патологического процесса. Ключевые слова: вирус папилломы человека, интраэпителиальные новообразования шейки матки, рак шейки матки.

Data of HPV genotype including 16 high-risk HPV (HR-HPV) and 4 low-risk HPV from 38,397 women with normal cytology, 1341 women with cervical cytology abnormalities, and 223 women with ISCC were retrospectively evaluated by a hospital-based study. The prevalence of high-risk HPV (HR-HPV) was 6.51%, 41.83%, and 96.86% in women with normal cytology, cervical cytology abnormalities, and ISCC, respectively. The three most common HPV types were HPV-52 (1.76%), HPV-16 (1.28%), and HPV-58 (0.97%) in women with normal cytology, whereas the most prevalent HPV type was HPV-16 (16.85%), followed by HPV-52 (9.55%) and HPV-58 (7.83%) in women with cervical cytology abnormalities. Specifically, HPV-16 had the highest frequency in ASC-H (24.16%, 36/149) and HSIL (35.71%, 110/308), while HPV-52 was the most common type in ASC-US (8.28%, 53/640) and LSIL (16.80%, 41/244). HPV-16 (75.78%), HPV18 (10.31%), and HPV58 (9.87%) were the most common types in women with ISCC. These data might contribute to increasing the knowledge of HPV epidemiology and providing the guide for vaccine selection for women in Shantou.
