Aims and background The aim of this study was to compare the local immune response in two groups of patients with high-grade cervical intraepithelial squamous lesions (SIL): one with HIV infection and the other with HPV infection alone. Materials and methods 16 conization specimens (8 from HIV-infected and 8 from non-HIV-infected patients) of HPV-related, high-grade SIL were selected. The specimens from non-HIV patients were considered as controls. The total number of Langerhans cells, CD4 and CD8 cells present in 10 field areas (3.120 mm2) was recorded in each case. In HIV patients CD4 and CD8 peripheral counts were performed immediately before surgery. Results The CD4/CD8 ratio never exceeded 0.71, whereas the lowest ratio in controls was 0.81: this difference was statistically significant (P=0.0009). The mean number of Langerhans cells was markedly reduced in the high-grade SILs in the HIV patients in comparison with controls (P=0.001). The number of CD4 cells and the CD4/CD8 ratio correlated with the peripheral CD4 count (P=0.001 and 0.02). Conclusions In our study a marked local impairment of cervical immunoreactivity was observed, which may play a major role in the progression of these lesions in HIV-infected women.

8029 Background: LYG is a rare angiocentric-destructive process with EBV+ B-cells and reactive T-cells. LYG is graded with grades I-II showing rare-moderate large EBV+ B-cells (usually polyclonal or oligoclonal) and grade III showing numerous large EBV+ B-cells (usually monoclonal), likely reflecting progressive transformation. Historically, steroids and/or chemotherapy have a 14 mos median survival. Methods: We are investigating Interferon-a (I-a) for grade I/II and dose-adjusted EPOCH ±Rituximab (R) for grade III LYG. Results: Characteristics of 53 pts are: male sex 68%; median age (range) 46 (17–67) and median ECOG P.S. 1 (0–3). Disease sites include lung 98%, CNS 38%, kidney 15%, skin 17%, liver 19% and nodes 4%. On study LYG grades are I-30%, II-26% and III-44%. Prior treatment was none-28%, chemotherapy± R-34%, and steroids alone-40% of pts. For grades I/II, I-a is begun at 7.5 million IUs TIW and escalated as tolerated until disease regression and continued 1 yr after CR. Of 31 patients treated with I-a, PFS is 62% at the median f/u of 5.3 yrs. Of 25 evaluable pts (3 NE; 3 TE), 60% had sustained CR for a median of 60 mos (4–175). In 9 pts who progressed on I-a, grade III was found in 5. Thus, in 20 pts with only grade I/II, 75% had sustained CR with I-a. In 11 evaluable pts with CNS disease, 81% achieved remission with I-a alone. The median time to remission is 9 mos (3–40) and median I-a dose is 20 MIU (7–40). Among 24 pts receiving DA-EPOCH±R, PFS is 40% at the median f/u of 28 mos. Of 21 evaluable pts (2 NE, 1 TE), 66% achieved CR. OS of all 53 pts is 68% at the median f/u of 4 yrs. Median EBV viral loads in 29 pts at study entry were 18 copies/10e6 genome equivalents (0–22727) (normal<200). Lymphocyte subsets in 30 pts showed a median CD4–428 (24–2322) and CD8–165 cells/mm3 (42–1316). In 12 pts in CR and with serial values, the mean CD8 cells (131 ± 44) (p2= 0.013) but not CD4 cells (65 ± 75) increased with treatment. Conclusions: High dose I-a produces sustained remissions in grade I/II LYG and is effective in CNS LYG. DA-EPOCH±R can produce durable CRs in grade III LYG. We hypothesize LYG emerges in a compromised immune milieu and undergoes progressive transformation if not effectively treated. Historical results suggest steroids may allow transformation by compromising immune function. No significant financial relationships to disclose.

Purpose. This study investigated the infection status and relationship between other common lower genital tract infectious pathogens and high-risk human papillomavirus (HR-HPV) in the high-grade cervical lesions. Methods. Overall, 882 patients were enrolled in this retrospective study, of which 339 patients (≥HSIL group) were confirmed with high-grade squamous intraepithelial lesions (HSIL) or cervical squamous cell carcinoma (SCC), while 543 patients (≤LSIL group) were diagnosed with low-grade squamous intraepithelial lesions (LSIL) or normal cervical pathology diagnosis. Cervical swab specimens were tested for HPV, pathogenic bacteria (PB), U. urealyticum (UU), M. hominis (MH), and C. trachomatis (CT) in both groups. Results. The infection rates of HR-HPV, PB, UU (at high density), and CT were higher in the ≥HSIL group than in the ≤LSIL group (P<0.001); however, higher infection rates with MH were not observed (P>0.05). PB, UU, and CT were associated with HR-HPV infection (P<0.001). The PB and UU infection rates in the ≥HSIL group were significantly different from those in the ≤LSIL group, regardless of whether there was an HR-HPV infection at the same time (P<0.05). However, this was not the case for the CT (P>0.05). Furthermore, 259 pathogenic bacterial strains were detected in 882 cases. The difference in the distribution of pathogenic bacterial flora in the different grades of cervical lesions had no statistical significance, which was prioritized over Escherichia coli (P>0.05). Conclusion. PB, UU, and CT infection is associated with susceptibility to HR-HPV, HR-HPV coinfection with these pathogens might increase the risk of high-grade cervical lesions, and PB and UU might be independent risk factors for cervical lesions.

ABSTRACT Objectives Human papillomavirus (HPV) is known to be associated with squamous intraepithelial lesions (SILs). However, there is limited and conflicting literature on the relationship between bacterial vaginosis (BV) and SIL. The aim of this study is to determine the prevalence of BV and evaluate the association between BV and SIL. Methods A retrospective study was performed on 10,546 cases between 2012 and 2017. HPV results were available in 7,081 cases. Results BV was present in 17.6% of cases. There was significant association between BV, positive HPV infection, and high-grade SIL. BV patients with negative HPV infection showed more squamous abnormalities than BV-negative HPV-negative patients. Conclusions We found there is a significant association between BV and SIL. BV is more common among patients with HPV infection and is independently associated with squamous abnormalities in cervical smears and surgical follow-up.

Abstract Background Persistent human papillomavirus (HPV) infection is a key factor for the development and progression of cervical cancer. We sought to identify the type-specific HPV prevalence by cervical cytology and assess disease progression risk based on high-risk persistent HPV infection in South Korea. Methods To investigate the HPV prevalence by Pap results, we searched seven literature databases without any language or date restrictions until July 17, 2019. To estimate the risk of disease progression by HPV type, we used the Korea HPV Cohort study data. The search included the terms “HPV” and “Genotype” and “Korea.” Studies on Korean women, type-specific HPV distribution by cytological findings, and detailed methodological description of the detection assay were included. We assessed the risk of disease progression according to the high-risk HPV type related to the nonavalent vaccine and associated persistent infections in 686 HPV-positive women with atypical squamous cells of uncertain significance or low-grade squamous intraepithelial lesions from the Korea HPV Cohort Study. Type-specific HPV prevalence was the proportion of women positive for a specific HPV genotype among all HPV-positive women tested for that genotype in the systematic review. Results We included 23 studies in our review. HPV-16 was the most prevalent, followed by HPV-58, -53, -70, -18, and -68. In women with high-grade squamous intraepithelial lesions, including cancer, HPV-16, -18, and -58 were the most prevalent. In the longitudinal cohort study, the adjusted hazard ratio of disease progression from atypical squamous cells of uncertain significance to high-grade squamous intraepithelial lesions was significantly higher among those with persistent HPV-58 (increase in risk: 3.54–5.84) and HPV-16 (2.64–5.04) infections. Conclusions While HPV-16 was the most prevalent, persistent infections of HPV-16/58 increased the risk of disease progression to high-grade squamous intraepithelial lesions. Therefore, persistent infections of HPV-16 and -58 are critical risk factors for cervical disease progression in Korea. Our results suggest that equal attention should be paid to HPV-58 and -16 infections and provide important evidence to assist in planning the National Immunization Program in Korea.

This study aimed to isolate and phenotype lymphocytes in untreated children patients with chronic allergic asthma. To reach such aim the study involved (25) patients from children (17 male and 9 female) whom their ages where between (3-10) years, in addition to (15) apparently healthy children (9 male and 6 female) in the same ages involved as control group. The data demonstrated that there was a significant increase in the mean percentages of T-lymphocytes (CD3+ cells) in the peripheral blood of patients (66.75±0.29)**, in comparison with control group (43.58±0.19), a significant increase in the mean percentages of T-helper lymphocytes (CD4+ cells) in the peripheral blood of patients (51.14±0.55), in comparison with control group (39.17±0.23) and the mean percentages of B-lymphocytes (CD20+ cells) was also increased significantly in the peripheral blood of patients (29.63±0.20) when it compared with the mean percentages of the same cells in control group (18.60±0.80). Besides a significant decrease in the mean percentages of T-suppressor lymphocytes (CD8+ cells) in the peripheral blood of patients (11.31±0.05), in comparison with control group (16.42±0.15). Finally the results of this study showed a significant increase in the mean percentages of the ratio of (CD4+ cells/CD8+ cells) in the peripheral blood of patients (55.34±0.41), in comparison with control group (31.25±0.09).

Abstract Background High-risk human papillomavirus (HR-HPV) infection is the main cause of cervical cancer, but additional alterations are necessary for its development. Abnormal DNA methylation has an important role in the origin and dissemination of cervical cancer and other human tumors. In this work, we analyzed the methylation of eight genes (AJAP1, CDH1, CDH13, MAGI2, MGMT, MYOD1, RASSF1A and SOX17) that participate in several biological processes for the maintenance of cell normality. We analyzed DNA methylation by methylation-specific PCR (MSP) and HPV infection using the INNO‑LiPA genotyping kit in 59 samples diagnostic of normal cervical tissue (non-SIL), 107 low-grade squamous intraepithelial lesions (LSILs), 29 high-grade squamous intraepithelial lesions (HSILs) and 51 cervical cancers (CCs). Results We found that all samples of LSIL, HSIL, and CC were HPV-positive, and the genotypes with higher frequencies were 16, 18, 51 and 56. In general, the genes analyzed displayed a significant tendency toward an increase in methylation levels according to increasing cervical lesion severity, except for the CDH13 gene. High CpG island methylator phenotype (CIMP) was associated with a 50.6-fold (95% CI 4.72–2267.3)-increased risk of HSIL and a 122-fold risk of CC (95% CI 10.04–5349.7). Conclusions We found that CIMP high was significantly associated with HSIL and CC risk. These results could indicate that CIMP together with HR-HPV infection and other factors participates in the development of HSIL and CC.

Background. Persistent human papillomavirus (HPV) infection is a necessary event in cervical cancer tumorigenesis. Our objectives were to estimate the rate of HPV infection persistence after large loop excision of the transformation zone (LEEP) in patients with high grade squamous intraepithelial lesions (HSIL) and to investigate if HPV persistence is type related.Methods. We conducted a prospective study on 89 patients with HSIL treated with LEEP. DNA HPV was performed before surgery and at 6, 12, and 18 months after LEEP.Results. Four patients were excluded from the study. The HPV persistence in the remaining 85 patients was 32.95% (6 months), 14.12% (12 months), and 10.59% (18 months). Type 16 had the highest persistence rate, 23.5% (6 months), 11.8% (12 months), and 8.2% (18 months). Coinfection was found to be 54.12% before LEEP and 18.8% (6 months), 4.7% (12 months), and 3.5% (18 months) after LEEP. The rate of coinfections including type 16 was 46.83% of all coinfections. Coinfection including type 16 was not correlated with higher persistence rate compared to infection with type 16 only.Conclusions. HPV infection is not completely eradicated by LEEP in patients with HSIL lesion on PAP smear. HPV persistence after LEEP is influenced by HPV type. HPV type 16 has the highest persistence rate.

Subpopulations of lymphoid cells were compared with respect to their ability to migrate into peripheral lymphoid organs of nonobese diabetic (NOD) mice and various strains of control mice. In short-term,in vivohoming studies, no major differences in the pattern of homing of B and T cells were observed among all mouse strains studied. On the other hand, CD4 cells localized consistently more efficiently than CD8 cells in both PP and LN of adult NOD and BALB/c mice, whereas both populations migrated roughly equivalently in LN of adult DBA/2, CBA, and C57BL/6 mice. No age-dependent differences in the homing of CD4 and CD8 cells were observed in BALB/c mice. On the contrary, in 2-week-old NOD mice, CD4 and CD8 cells migrated equally well. The preferential entry of CD4 cells in adult NOD and BALB/c did not result from increased blood transit time of CD8 cells. On the other hand, the preferential migration of CD8 cells was observed in the liver, whereas the two T-cell subsets migrated equally well in the lungs. The differences in the homing characteristics of CD4 and CD8 cells among NOD, BALB/c, and C57BL/6 mice were not related to modifications in the level of expression of adhesion molecules such as MEL-14, LFA-1, and Pgp-1.

Currently, Papanicolaou smears are proposed at three-year intervals for cervical screening to all women living with HIV. The aim of this retrospective cohort study was to provide data on the incidence of cervical high-grade squamous intraepithelial lesions (HSIL) in cervical smear confirmed by histology in HIV-1-infected women (two consecutive normal Papanicolaou smears at baseline) after a long-term follow-up. Sixty-seven women (recruited between March 1999 and January 2003) were analyzed. The median period of follow-up was 13.2 years (range: 7.4–17.1 years) with a total of 583 Papanicolaou smears. Twenty-seven percent of these HIV-1-infected women had poorly-controlled HIV. Cumulative incidence of HSIL was 18% (12/67; 95%CI: 11–29%) of which one was an invasive squamous cell carcinoma and two were carcinoma in situ. These women had not been well-engaged with the annual Papanicolaou smear screening program and had poor adherence to antiretroviral therapy. Development of HSIL was associated with high-risk-HPV infection (OR: 14.9; 95%CI: 3.0, 75.1). At last Papanicolaou smear, prevalence of high-risk-HPV infection was 30% (20/66, 95%CI: 21–42%). In conclusion, the incidence of cervical HSIL in HIV-1-infected women with poor antiretroviral therapy adherence or poor immunological status reinforces the need to identify those HIV-1-infected women at risk of developing cervical cancer.
