Efficacy of a Coriolus versicolor-Based Vaginal Gel in Women With Human Papillomavirus-Dependent Cervical Lesions: The PALOMA Study.

OBJECTIVE: The aim of the study was to evaluate the efficacy of Papilocare, a Coriolus versicolor-based vaginal gel, in repairing human papillomavirus (HPV)-related low-grade cervical lesions. METHODS: The study is a multicenter, open-label, randomized, parallel-group, watchful waiting approach-controlled trial involving 91 HPV-positive women with low-grade Pap smear alterations and consistent colposcopy. RESULTS: The percentage of patients with normal Pap smear and concordant colposcopy 3 and 6 months after receiving treatment (78.0% and 84.9%) was significantly higher than without treatment (54.8% and 64.5%), especially in high-risk HPV patients (79.5% and 87.8% vs 52.0% and 56.0%). At 6-month visit, overall HPV clearance was achieved by a greater number of patients receiving treatment (59.6%) compared with those without treatment (41.9%), especially high-risk HPV ones (62.5% vs 40.0%). The cervical re-epithelization score was significantly higher with treatment (mean = 4.5) than without (mean = 4.1). Compared with baseline, perceived stress decreased in the treatment group (from 21.1 to 19.0) and increased in the control group (from 17.7 to 20.7). A total of 7 possible or probable treatment-related adverse events were reported, most of them (n = 6) being mild or moderate in severity. CONCLUSIONS: Treatment with Papilocare has demonstrated a better clinical benefit than the conventional watchful waiting approach in clinical practice for total and high-risk HPV patients in terms of its efficacy to treat HPV-related cervical lesions and to clear all HPV strains after a single 6-month period. It has demonstrated an adequate safety and tolerability and confers additional benefits such as higher re-epithelization, stress reduction, and high treatment adherence.

Pituitary response profile following metoclopramide administration in women with different forms of hyperprolactinemia.

AIMS: To test the hypothesis that macroprolactinemia is an extra-pituitary phenomenon by showing that the pituitary production of prolactin in patients with hyperprolactinemia due to macroprolactin is comparable to that in normoprolactinemic women and different from that in women with monomeric hyperprolactinemia. METHODS: Twenty-five women were studied: eight with macroprolactin hyperprolactinemia, eight with monomeric hyperprolactinemia, and nine controls. Prolactin levels were measured before and after precipitation with polyethylene glycol at baseline and at 5, 10,15, 30, and 60 min after metoclopramide administration (10 mg i.v.) in the three groups. RESULTS: The response profile of total and monomeric prolactin following the administration of metoclopramide was similar in women with monomeric hyperprolactinemia and normoprolactinemia but different in women with macroprolactinemia. The areas under the curve for total and monomeric prolactin were higher in patients with macroprolactinemia than in the other two groups (p < 0·0001). The maximal concentration of monomeric prolactin was reached before that of total prolactin in macroprolactinemic patients but the differences were not significant. DISCUSSION: Our findings support the hypothesis that prolactin secretion is comparable in women with macroprolactinemia and in normoprolactinemic women. The dynamics of the secretion suggest that the formation of prolactin complexes is an extra-pituitary process.

Human papillomavirus infection in HIV-1 infected women in Catalonia (Spain): implications for prevention of cervical cancer.

BACKGROUND: High-risk human Papillomavirus infection is a necessary factor for cervical squamous intraepithelial lesions and invasive cervical cancer. In HIV-1-infected women, HPV infection is more prevalent and a higher risk of cervical cancer has been identified. We aimed to calculate the prevalence of infection by HR-HPV, determine the factors associated with this infection and abnormal cytology findings and to describe the history of cervical cancer screening in HIV-1-infected women. METHODS: We enrolled 479 HIV-1-infected women from the PISCIS cohort. Each patient underwent a gynecological check-up, PAP smear, HPV AND Hybrid capture, HPV genotyping, and colposcopy and biopsy, if necessary. We applied questionnaires to obtain information on sociodemographic, behavioral, clinical, and cervical screening variables. We present a cross-sectional analysis. RESULTS: Median age was 42 years. The prevalence of HR-HPV infection was 33.2% and that of high-grade squamous intraepithelial lesions (HSIL) was 3.8%. The most common genotypes were 16(23%), 53(20.3%), and 52(16.2%). The factor associated with HR-HPV infection was age <30 years (odds ratio[OR],2.5; 95%confidence interval[CI],1.1-5.6). The factors associated with the presence of HSIL or low-grade squamous intraepithelial lesions (LSIL) were CD4T-lymphocyte count <200 cells/mm(3) versus >500 cells/mm(3) (OR,8.4; 95%CI,3.7-19.2), HIV-1 viral load >10,000 copies/mL versus <400 copies/mL (OR,2.1; 95%CI,1.0-4.4), and use of oral contraceptives (OR,2.0; 95%CI,1.0-3.9). Sixty percent of HIV-1-infected women had had one Pap smear within the last 2 years. CONCLUSIONS: The high prevalence of HPV infection and cervical lesions in the HIV-1-infected population in Catalonia, as well as the low coverage and frequency of screening in this group, means that better preventive efforts are necessary and should include vaccination against HPV, better accessibility to screening programs, training of health care professionals, and specific health education for HIV-1-infected women.
