Microsporidiosis is considered to be emerging opportunistic infection in immunocompromised individuals worldwide. The aim of this study was to identify the specific serum antibodies to intestinal microsporidia Encephalitozoon cuniculi and Encephalitozoon intestinalis in women with Human Papillomavirus HPV and without HPV by the indirect immunofluorescence (IFA). From total number of 669 examined women, 225 were HPV positive and 444 women HPV negative. Overall the study comprised of 10.8% women with positive result for presence of E. cuniculi antibodies. In group 1 (HPV-positive women) it was more than 28% and in group 2 (HPV-negative women) it was less than 2% (p<0.001). E. intestinalis infection was found in total of 4.48% women, in group 1 it was present in less than 6% and in group 2 in less than 4% of women.

This systematic review and meta-analysis evaluate human papillomavirus (HPV) prevalence, genotype distribution, and associations with cervicovaginal microbiota and cytokine profiles among South African women, where cervical cancer ranks as the second most common cancer. PubMed, SCOPUS, and Web of Science were searched for studies on HPV infection up to 21 September 2024. The pooled prevalence was estimated using a random-effects model, with subgroup analyses by province, sample type, and HIV status.

Objective: With the transition from cytology to human papilloma virus (HPV) testing in cervical cancer screening, it is possible to use self-sampling instead of professionally collected samples. Most studies have included women between 20 and 60 years age. Here we aimed to study postmenopausal women and investigate whether vaginal self-sampling is equally effective as professional sampling for detection of HSIL and the possibility to use a method for molecular triage directly on the screening sample.

Background: Understanding the HPV genotype distribution in invasive cervical cancer (ICC) is essential for vaccine optimization. This study presents a comprehensive analysis of HPV genotypes in ICC tissues from patients in western China, with the aim of informing regional vaccine policy and prevention strategies.
Methods: DNA was extracted from 1,908 paraffin-embedded ICC samples, and 23 HPV genotypes were detected via PCR and reverse dot hybridization gene chip assays.

Article Synopsis
- The study explored the link between human papillomavirus (HPV) integration and the risk of developing cervical intraepithelial neoplasia (CIN) among women in China.
- It involved 4,086 women, assessing their HPV status and cervical cells over several years, finding that HPV integration was significantly associated with more severe cervical pathology.
- HPV integration testing proved to be more specific and yielded a lower referral rate for further examination compared to standard cytology, suggesting it could be an effective triage method for HPV-positive patients.

Background: Observational studies suggest circulating tumor HPV DNA may facilitate early detection of recurrent HPV-positive oropharynx cancer (OPC). We prospectively investigated whether biomarker-guided surveillance detects recurrence sooner than standard-of-care.
Patients And Methods: We enrolled patients evaluated for HPV-positive OPC at a single center 11/2020-4/2023 undergoing curative-intent treatment in a single-arm cohort study.
