Infection with HPV is very common and it is associated with benign and malignant proliferation of skin and squamous mucosae. Many HPVs, considered lowrisk such as HPV 6 and 11, produce warts; while highrisk viruses, such as HPVs 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, and 58, induce tumors. About 5% of all cancers in men and women are associated with HPV infection. Because there are not antiviral drugs for HPV infection, current therapies for low-risk HPV infections involve physical removal of the lesion by cryotherapy, trichloracetic acid, laser, or surgical removal. Surgical procedures are effective in the treatment of precancerous lesions, however after these procedures, many recurrences appear due to new re-infections, or to failure of the procedure to eliminate the HPV. In addition, HPV can inhibit recognition of malignant cellsby the immune system, leading to the development of cancer lesions. When this occurs, radiotherapy and chemotherapy are then used. Unfortunately, about 50% of the HPV-cancer patients still die. In the past decade, a better knowledge of the natural history of the virushost interaction and of the immune response against this viral infection has brought new therapeutic strategies geared to modulate the immune system to generate an efficient virus-specific cytotoxic response. Novel HPV protein-expressing vaccines have shown some significant clinical efficacy and systemic HPV-specific cytotoxic T cell responses. This review will describe the current status of the several therapeutic strategies used to treat HPV-induced lesions, and discuss the various new therapies now being tested.展开更多

In many parts of the world, studies are being carried out to understand the different genotypes to better tackle this issue. We conducted a study to determine the prevalence of HPV genotypes in women with chronic hepatitis B or C infection, co-infected or not with HIV, treated at the Hôpital Saint Camille in Ouagadougou (Burkina Faso). Methods: This study was conducted from April to July 2023, including 100 women in gastroenterology at Hôpital Saint Camille. A questionnaire on their socio-demographic and life style was administrated;and endocervical samples were collected using sterile swabs and then sent to Centre of Biomolecular Research Pietro Annigoni (CERBA). HPV molecular detection and genotyping were performed by PCR and hybridization using the HPV Direct Flow Chips kit. Data were analysis using chi square test or Fischer’s exact test with a significance threshold for p Results: The prevalence of HPV infection was 28% (28/100) on the sample of women tested. The most frequent genotypes were HPV 52 (8.33%), followed by HPV 18 and 68 (6.25% each) for high-risk HPVs, and HPV 6, 44/55 and 62/81 (8.33% each) for low-risk HPVs. Conclusion: This study, the first of its kind in Burkina Faso on this group of the population, reveals that the most frequent genotypes found in this study are not included in the vaccine available in Burkina Faso (Gardasil<sup>®</sup>4).展开更多

The Gene-Eden-VIR formula was designed to target latent viruses. Therefore, the theory predicts that treatment with Gene-Eden-VIR will decrease fatigue in individuals infected with a latent virus. The objective of this study was to test this prediction. Framework: A post marketing clinical study that followed FDA guidelines. Treatment: Gene-Eden-VIR, a dietary supplement. A capsule of Gene-Eden-VIR includes 100 mg of quercetin, 150 mg of green tea extract, 50 mg of cinnamon extract, 25 mg of licorice extract, and 100 mcg of selenium. The treatment included 1, 2, 3, or 4 capsules per day, and lasted 2 to 54 weeks. Population: 100 individuals infected with a latent virus, including the Human Papillomavirus (HPV), Epstein Barr Virus (EBV), Herpes Simplex Virus (HSV), Human Cytomegalovirus (HCMV), and Hepatitis C Virus (HCV). Ages ranged from 20 to 66. All participants reported a feeling of fatigue at the start of the study. Specifically, 98, 90, and 79 participants reported a feeling of general, physical, and mental fatigue, respectively. Results: Following treatment with Gene-Eden-VIR, 73.47%, 62.22%, and 47.36% reported a decrease in their feeling of general, physical, and mental fatigue, respectively. The participants also reported a statistically significant decrease in every aspect of fatigue tested in the study. The results also showed a duration effect, that is, those treated for 2 months or more reported a larger decrease in their feeling of fatigue (general, p = 0.03, n = 65;physical and mental, p = 0.05, n = 70). The results showed no interviewer bias, and no selection bias. In addition, the results showed therapeutic consistency under varying manufacturing conditions. The participants reported no side effects after taking Gene-Eden-VIR. Conclusions: This post marketing clinical study showed that treatment with Gene-Eden-VIR safely decrea展开更多
