Combination of biopsy forceps excision and ALA-PDT for the treatment of cervical condylomata acuminata.

BACKGROUND: Human papilloma virus (HPV) infection and cervical condyloma acuminatum (CA) often co-exist. Although there are many methods to treat cervical CA, high recurrence rate and cervical scars are still troublesome. Biopsy forceps excision combined with 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a feasible approach for cervical CA, but its efficacy and limitation need to be evaluated. METHODS: This retrospective study consisted of 49 patients aged 18-50 years with a histologically or colposcopic confirmed cervical CA and with HPV infection. Patients were treated with biopsy forceps excision and ALA-PDT. The efficacy was evaluated through HPV typing and colposcopy directed biopsy. RESULTS: Three months after the combination treatment the total lesion remission rate was 93.88 % (46/49) and the HPV clearance rate was 83.67 % (41/49). One patients showed some residual lesions and two patients showed new lesions. Recurrence rate was 4.34 % at 6 months follow-up. There was no significant difference in HPV clearance rate at 3 and 6 months follow-up. Univariate analysis showed that the combination treatment was less effective for patients who had size of visible lesion > 1.5 cm2. Adverse effects were minimal and no structural complications were reported. The main side effects were abdominal pain and increased vaginal secretions. CONCLUSION: Combination of biopsy forceps excision and ALA-PDT is safe and effective for eliminating cervical condylomata lesion and eradicating HPV infection. Colposcopic evaluation is recommended before and after treatment.

[Anogenital warts-An update]. / Anogenitalwarzen ­ ein Update.

With a prevalence of around 1% in the sexually active population anogenital warts are the most frequent human papillomavirus (HPV)-related disease. In the vast majority of cases the underlying cause of the infection is due to HPV types 6 and 11. The diagnosis can usually be clinically established but in certain cases a histopathological work-up can be useful. Buschke-Lowenstein tumors represent such a scenario. The current therapeutic armamentarium for anogenital warts ranges from surgical ablative procedures up to local immunomodulatory treatment. All procedures have different advantages and disadvantages and are relatively time-consuming and sometimes also unpleasant for the patient. Anogenital warts are also a possible expression of an incomplete immunological control of HPV. Therefore, it should be emphasized that for certain affected individuals, especially immunosuppressed patients, special attention should be given to ensuring that screening investigations for HPV-associated dysplasia is carried out according to the respective valid guidelines. The primary prophylaxis by vaccination of girls and boys prior to first HPV exposure represents a very effective option to drastically reduce the prevalence of anogenital warts and other HPV-related diseases.

Quadrivalent HPV vaccine effectiveness against anogenital warts: A registry-based study of 2,2 million individuals.

BACKGROUND: In 2009, Norway initiated routine quadrivalent HPV (qHPV) vaccination for girls at 12-13 years of age to protect against virus types causing cervical cancer, HPV16/18, and HPV6/11 which cause anogenital warts (AGW). We wanted to investigate qHPV vaccine effectiveness (VE) against AGW in females before and after first AGW episode and to assess the impact of female vaccination in males. MATERIALS AND METHODS: QHPV vaccination and AGW episodes were collected for the time period 2006-2016 for birth cohorts 1975-2003. Cox models were applied to age at first, as well as at second AGW episode. Finally, we estimated the impact of the female vaccination program on unvaccinated males. RESULTS: The VE against the first episode of AGW was strongly dependent on vaccination age, with hazard ratios (HRs) compared to unvaccinated individuals of 0.2, 0.2, 0.3, 0.5, 1.0, 1.3, and 2.7, for age groups of ⩽13, 14-15, 16-17, 18-19, 20-24, 25-29, and 30+ years at first vaccination, respectively. Among women who had suffered a first episode of AGW, subsequent qHPV vaccination did not protect against a second episode, with HRs of 0.8, 1.0, and 1.4, for age groups of ⩽17, 18-24, and 25+ years at first vaccination. A gradually decreasing AGW risk was seen in unvaccinated male cohorts neighboring the first routinely vaccinated female 1997 cohort. CONCLUSIONS: When administered before 14 years of age, qHPV vaccination reduced the probability of AGW about fivefold. The effect decreased sharply with vaccination age, and was not significant among women vaccinated after age 20 years. QHPV administered after the first AGW episode did not protect against a second AGW episode. Herd effects were indicated in unvaccinated males, as we observed a gradual decrease in AGW rates from the 1993 male birth cohort and onwards.

WTAP-mediated m6A modification of IFNE is required for antiviral defense in condyloma acuminata.

BACKGROUND: IFN-ε is essential in combating viral infections, particularly in epithelial cells and protected mucosal tissues. Its protective effects have been demonstrated against HSV2, Zika virus, HIV and SARS-COV2. However, the specific expression and role of IFN-ε in skin keratinocytes and HPV infection are still not fully understood and require further investigation. OBJECTIVE: In this study, we aimed to investigate the functions and expression mechanism of IFN-ε in keratinocytes during HPV infection and the progression of condyloma acuminata. METHODS: Keratinocytes isolated from biopsied CA warts and normal skins samples were analyzed by MeRIP-seq analysis. IFN-ε and WTAP in CA warts and normal skins were analyzed by immunostaining and qPCR. RESULTS: In this study, we identified IFN-ɛ was markedly upregulated in CA warts and HPV-infected keratinocytes. IFN-ɛ expression also showed negatively correlation with the size of CA warts (R=-0.4646, P = 0.009). IFN-ɛ suppressed the susceptibility of HPV infection directly. m6A analysis reveals WTAP is a key m6A writer promoting the m6A modification of IFNE mRNA. CONCLUSION: Our research suggests that IFN-ɛ is an important Type I IFN cytokine involved in the development of genital warts. Furthermore, we found that HPV infection affects the m6A modifications of IFNE through a mechanism dependent on WTAP. This study provides insights into the innate immune response of the host to HPV infection and may contribute to the development of future strategies for regulating innate immunity to treat genital warts.

Treatment of condylomata acuminata caused by low-risk human papillomavirus with chloroquine phosphate gel.

Objective: To observe the stability and therapeutic effect of chloroquine phosphate gel on human condylomata acuminata (CA) caused by low-risk human papillomavirus (HPV). Methods: The appearance, viscosity, pH, chloroquine concentration, deethylchloroquine concentration and content uniformity of chloroquine phosphate gel were examined for 24 months, the gel met the quality standards throughout the 24-month observation. A nude mouse model harboring CA xenografts was used to observe the therapeutic effect of this gel on CA in vivo. Results: After 14 days of gel administration, compared with the control group, the treatment group had significantly smaller warts and significantly reduced DNA copy numbers of HPV6 and HPV11 in the wart tissues. Immunohistochemistry analysis of p53 protein expression in the wart tissues of the treatment group was significantly increased. Conclusion: Chloroquine phosphate gel was stable and effective against CA, possibly through the promotion of p53 protein expression to induce apoptosis, leading to the involution of warts.

Methodological quality of systematic reviews of the local management of anogenital warts: a systematic review using AMSTAR II, ROBIS and PRISMA.

INTRODUCTION: Anogenital warts (AGWs) are among the most common STDs. Many therapy options are available but are not codified. Systematic reviews (SRs) and meta-analyses (MAs) are helpful to elaborate recommendations on the management of AGWs. The objective of our study was to assess the quality and consistency of SRs for the local management of AGWs using three international tools. METHODS: Seven electronic databases were searched from inception to 10 January 2022 for this SR. The intervention of interest was any local treatment of AGWs. There was no restriction on language and population. The methodological quality, reporting quality and risk of bias (ROB) of the included SRs for the local treatments of AGWs were assessed independently by two investigators with A Measurement Tool to Assess systematic Reviews version II (AMSTAR II), Risk of Bias in Systematic Reviews (ROBIS) and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). RESULTS: Twenty-two SRs/MAs met all inclusion criteria. According to the results of the AMSTAR II, nine included reviews were rated critically as being of low quality, and only five were of high quality. Based on the ROBIS tool, only nine SRs/MAs had a low ROB. The domain-assessed 'study eligibility criteria' were mostly rated at a low ROB, unlike the other domains. With PRISMA, the reporting checklist was relatively complete for ten SRs/MAs, but some reporting weaknesses remained in the topics of the abstract, protocol and registration, ROB and funding. DISCUSSION: Several therapy options are available for the local management of AGWs and are widely studied. However, due to the many ROB and low quality of these SRs/MAs, only a few of them have the sufficient methodological quality to support guidelines. PROSPERO REGISTRATION NUMBER: CRD42021265175.

A Case of Giant Perianal Condylomata Acuminata with IgA Nephropathy Treated Successfully by a Topical Chinese Medicine Preparation Paiteling.

Giant condylomata acuminata (a sexually transmitted disease caused by HPV infection) currently is treated in many methods. Surgery, the mainstay treatment of giant condylomata acuminata, may cause a high cost or scar formation. It is important to explore effective and safe treatment options. Although the external treatment of traditional Chinese medicine treatment of condyloma acuminatum has not been widely used, in our case, the use of traditional Chinese medicine successfully treated a perianal giant condyloma acuminatum patient who also suffered from mixed hemorrhoid and IgA nephropathy meanwhile. The treatment process was simple and the effect obvious. There was no recurrence more than 10 months after treatment finished, and the patients felt safe, comfortable and highly coordinated. The outcome of this case suggests that the traditional Chinese medicine might be considered as a mild and effective option for the treatment of giant condyloma acuminatum.

HPV-Induced Anal and Peri-Anal Neoplasia, a Surgeon's Experience: 5-Year Case Series.

Purpose: One of the most known sexually transmitted diseases is Condylomata acuminata (CA), a skin lesion occurring due to infection from Human Papilloma Virus (HPV). CA has a typical appearance of raised, skin-colored papules ranging in size from 1 mm to 5 mm. These lesions often form cauliflower-like plaques. Depending on the involved HPV-subtype (either high-risk or low-risk) and its malignant potential, these lesions are likely to lead to malignant transformation when specific HPV subtypes and other risk factors are present. Therefore, high clinical suspicion is required when examining the anal and perianal area. Methods: In this article, the authors aim to present the results of a five-year case series (2016-2021) of anal and perianal cases of CA. Results: A total of 35 patients were included in this study. Patients were categorized based on specific criteria, which included gender, sex preferences, and human immunodeficiency virus infection. All patients underwent proctoscopy and excision biopsies were obtained. Based on dysplasia grade patients were further categorized. The group of patients where high-dysplasia squamous cell carcinoma was present was initially treated with chemoradiotherapy. Abdominoperineal resection was necessary in five cases after local recurrence. Conclusions: CA remains a serious condition where several treatment options are available if detected early. Delay in diagnosis can lead to malignant transformation, often leaving abdominoperineal resection as the only option. Vaccination against HPV poses a key role in eliminating the transmission of the virus, and thus the prevalence of CA.

5-aminolevulinic acid photodynamic therapy combined with wart curettage treatment for intractable urethral condylomata acuminata. A case report.

Condylomata acuminata (CA) is caused by human papillomavirus (HPV). It is one of the most common sexually transmitted diseases (STD). The lesions mainly occur in the external genitalia and perianal areas, rarely involves in urethral and usually localized at the distal 3 cm of the urethral orifice. Because of the special anatomical site, treating urethral CA is challenging and it has high recurrence rate after treatment. 5-aminolevulinic acid photodynamic therapy (ALA-PDT) can successfully treat urethral CA, however, the experience of using ALA-PDT combined with wart curettage to treat intractable urethral CA is still very limited. In here, we reported an intractable urethral CA case with effective remission after receiving combination therapy. Wart curettage combine with ALA-PDT is an expeditious, economical, and well-tolerated treatment method.

Radical surgical management of perianal giant condyloma acuminatum of Buschke and Löwenstein: long-term results of 11 cases.

PURPOSE: Perianal Buschke-Löwenstein tumor (BLT) is characterized by an exophytic cauliflower-like mass surrounding the perianal region. Its tendency to infiltrate the adjacent tissues, its massiveness, and its high recurrence rate cause difficulties in treatment. The aim of this study is to report our strategy with wide local excision and flap reconstruction for BLT. METHODS: From November 2002 to June 2019, 11 patients (9 men) with a mean age of 33.45 years (range, 19-54 years) were operated on for BLT. All patients underwent wide local excision and V-Y flap reconstruction, supplemented with other flaps whenever needed. No additional modalities were used. RESULTS: Two patients had a history of anal intercourse while all patients were human immunodeficiency virus-negative. The mean tumor length was 15.54 ± 1.34 cm (range, 10-26 cm). Human papillomavirus 6 was the most common type identified. Partial wound dehiscence developed in 3 patients, while anal stenosis, mucosal ectropion, or local recurrence was not observed during the mean follow-up period of 50.45 ± 1.75 months (range, 10-196 months). CONCLUSION: In patients with perianal BLT, wide local excision and flap reconstruction result in a high healing rate without significant complications.

Photodynamic therapy in the treatment of condyloma acuminata: A systematic review of clinical trials.

INTRODUCTION: Condylomata acuminata (CA) is a sexually transmitted infection with a high prevalence associated with psychosexual morbidity in both men and women of various age. Up to now, treatment modalities yield low clearance and recurrence rate (RR) and are also deemed low quality evidence-wise. Photodynamic therapy (PDT) is a novel and promising therapy to effectively cure and prevent CA recurrence. METHOD: This systematic review was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) and registered to the International Prospective Register of Systematic Review (PROSPERO) (CRD42022332760). RESULTS: Ten studies were included in this systematic review. A significant value of complete response (CR) ranging from 63-100% in patients with genital warts after receiving several sessions of PDT. A relatively low recurrence rate was seen in all 10 studies, with an RR of less than 17%. Quality assessment of included studies reported mostly high-quality research. CONCLUSIONS: PDT therapy resulted in a higher CR with significantly lower RR compared to other therapies. Thus, PDT can be an alternative treatment of CA with low RR and minimal side effects. Additional research, especially randomized clinical trials in various countries, is needed to further substantiate this treatment and formulate definitive protocols.

Changes of high mobility group protein B1 in condyloma acuminatum and its clinical significance / 中国医师进修杂志

Objective:To investigate the changes and clinical significance of high mobility group protein B1 (HMGB1) in condyloma acuminatum (CA).Methods:Sixty four patients with initial CA(initial group) and 48 patients with recurrent CA(recurrent goup) treated in the Second Affiliated Hospital of PLA Air Force Military Medical University Hospital from January 2019 to November 2020 were included. In the same period, 31 patients who underwent circumcision and 19 female underwent sexual organ cosmetic plastic surgery were taken as the control group, and the normal foreskin and healthy vulva were collected. The expression of HMGB1 in wart was detected by real-time quantitative polymerase chain reaction(RT-PCR), and the expression of soluble apoptosis related factor ligand (sFasL), cell lymphoma-2 gene (Bcl-2), soluble apoptosis related factor (SFAS) and Survivin, caspase-3 were detected. At the same time, serum interleukin (IL) - 6, IL-17, IL-23 and tumor necrosis factor - α (TNF- α) were detected by enzyme-linked immunosorbent assay(ELISA).Results:The expression of HMGB1 mRNA in the warts of patients in the initial group, recurrence group and control group were 1.96 ± 0.20, 1.53 ± 0.14, 1.05 ± 0.11, there was statistical difference ( F = 15.20, P<0.05) ; the expression of HMGB1 mRNA in the warts of patients in the initial group was significantly higher than that in the recurrence group and the control group ( P<0.05), and the recurrence group was also significantly higher than that in the control group ( P<0.05). The mRNA expressions of sFas, Bcl-2, sFasL and caspase-3 in the warts of patients in the initial group were significantly lower than those in the recurrence group and the control group: 0.52 ± 0.08 vs. 0.82 ± 0.16, 1.10 ± 0.19; 0.50 ± 0.05 vs. 0.79 ± 0.13, 1.08 ± 0.21; 0.47 ± 0.06 vs. 0.81 ± 0.15, 1.01 ± 0.19; 0.35 ± 0.04 vs. 0.68 ± 0.09, 0.91 ± 0.16, P<0.05; and the recurrence group were also significantly lower than those in the control group ( P<0.05). The expression of Survivin mRNA in the warts of patients in the initial group was significantly higher than those in the recurrence group and the control group: 2.14 ± 0.40 vs. 1.60 ± 0.27, 0.99 ± 0.18, P<0.05, and the recurrence group was also significantly higher than that in the control group ( P<0.05). The serum levels of TNF-α and IL-6 in the initial group were significantly lower than that in the recurrence group and the control group: (20.08 ± 1.95) μg/L vs. (26.93 ± 2.74), (37.65 ± 3.83) μg/L; (31.05 ± 3.24) μg/L vs. (38.13 ± 3.76), (45.98 ± 4.69) μg/L, P<0.05; and the recurrence group were also significantly lower than those in the control group ( P<0.05). The serum levels of IL-17 and IL-23 in the primary group were significantly higher than those in the recurrence group and the control group: (423.71 ± 28.68) ng/L vs. (384.26 ± 21.70) and (335.43 ± 19.65) ng/L; (289.50 ± 18.53) ng/L vs. (251.07 ± 15.96) and (214.67 ± 13.20) ng/L, P<0.05; and the recurrence group were also significantly higher than those in the control group ( P<0.05). The results of correlation analysis showed that the mRNA expression of HMGB1 in the warts of CA patients were negatively correlated with the mRNA expression of caspase-3, sFas, Bcl-2 and sFasL in the warts ( r = - 0.602, - 0.734, - 0.692, - 0.717, P<0.05), and was positive correlation with Survivin mRNA expression ( r = 0.645, P<0.05); and were positive correlation with the contents of IL-17 and IL-23 in serum ( r = 0.673, 0.685, P<0.05), and negatively correlated with the contents of TNF-α and IL-6 ( r = - 0.698, - 0.764, P<0.05). Conclusions:HMGB1 is obviously abnormal in the warts of patients with condyloma acuminatum, and is closely related to apoptosis, immune and inflammation-related factors, and may be jointly involved in the occurrence and recurrence of CA.

Lichenoid lesions around the anus: An unusual site of Hailey-Hailey disease.

The anal region is an unusual site of Hailey-Hailey disease. It manifests with lichenoid lesions with crusted erosions around the anus. It should be differentiated from condylomata acuminata, extramammary Paget disease, and bowenoid papulosis.

Pemphigus vegetans misdiagnosed as condylomata acuminata: A case report.

Pemphigus vegetans is a rare variant of pemphigus vulgaris, characterized by vegetating lesions primarily in the flexures. A 41-year-old male patient presented with pemphigus vegetans highly mimicking condylomata acuminata, which led to mistreatment. Careful analysis of clinical and laboratory findings enabled us to reach a correct diagnosis and successful treatment.

Diagnostic Pearls of Vulvar Epidermolytic Acanthoma: Case Report.

Epidermolytic acanthomas (EA) are uncommon benign tumors clinically presenting as single to multiple papules. Histologically, EA display hyperkeratosis, hypergranulosis, acanthosis, and epidermal degeneration-also known as epidermolytic hyperkeratosis (EH). EA may be misdiagnosed as condyloma both clinically and histopathologically when located on the genitalia. Thus, this diagnosis carries a significant psychological burden and must remain in the differential when initially considering genital warts. We utilize the case of a 62-year old female referred to dermatology for a 5-year history of multiple pruritic and hypopigmented vulvar papules-misdiagnosed as genital warts-to highlight the impact of differentiating EA from genital warts. This patient was initially misdiagnosed with common genital warts at her gynecologist's office and treated unsuccessfully for years. A shave biopsy was performed and histology revealed EH, consistent with EA.

Buske-Lowenstein Tumor: A Rare Cause of Genital Warts.

The Buschke-Löwenstein tumor (BLT), also known as giant condylomata acuminata (GCA), is a pseudo-epithelial proliferation engendered by the human papillomavirus (HPV). Interestingly, its location at the anal margin, or perianal skin, is rare. The authors present the case of a gentleman who became unstable while standing, stating that his ears were ringing. His emergency presentation, clinical course, and imaging findings are discussed. The patient presented with signs of condyloma acuminata and BLT. This can be excised through surgery and removed with the help of adjuvant treatments, but there is still much to learn about this disease.

Treatment of Condylomata Acuminata Using a New Non-Vapor-Generating Focused Ultrasound Method following Imiquimod 5% Cream.

Condylomata acuminata is the most common sexually transmitted disease in the world. Physical treatments include excision, cryotherapy, electrocautery and ablative CO2, and Nd:YAG laser ablation, while topical treatments include imiquimod immunotherapy and antimitotic podophyllotoxin or sinecatechins. Efficacies of all methods are low, and recurrences are very common. A new combined method is presented as a single case in a 25-year-old male patient diagnosed with numerous condylomas on the penis, scrotum, and lower abdomen. The treatment consisted of a 7-week topical monotherapy using 5% imiquimod cream followed by local treatment with 20 MHz high-intensity focused ultrasound on remaining recalcitrant lesions. Results showed resolution of approximately 70% of the condylomas after imiquimod treatment, and full resolution of all recalcitrant condylomas treated subsequently with high-intensity focused ultrasound. The method is concluded to be safe and effective and, furthermore, presents a new physical method that does not generate airborne infectious human papillomavirus particles that pose a health risk for the medical team performing therapy. Further studies in larger populations are recommended to confirm the combined efficacy of the proposed method.
