Vaginal infection of mice with HSV type 2 variant ER−: A new animal model for human primary genital HSV type 2 infections
1992
Abstract Studying the pathogenesis of vaginal infections in mice with two variants of Herpes simplex virus type 2 (HSV-2) strain ER we observed that both variants ER+ and ER− caused severe vaginitis but only ER+ invaded the CNS leading to lethal neurological disease. In contrast, mice infected with ER− cleared the virus from the vagina and recovered from infection. ER+ and ER− expressed equal levels of thymidine kinase (TK) indicating a TK-independent difference in neurovirulence. Using the non-neurovirulent variant ER−, we were able to investigate humoral immune responses late after infection. Vaginal infection with ER− suppressed serum antibody formation after a secondary systemic HSV-1 i…
Gynecological adverse effects of natalizumab administration: Case report and review of the literature.
2018
Abstract Background Natalizumab is administered for the treatment of relapsing-remitting multiple sclerosis (RR-MS) with high disease activity.Natalizumab therapy has been associated with adverse effects, such as progressive multifocal leukoencephalopathy, liver damage, nasopharyngitis, urinary tract infection, urticaria, cephalgia, dizziness, fatigue, nausea, fever, rigidity, anxiety and gastroenteritis. Objective To describe a case of a woman with RR-MS who developed recurrent vaginitis on natalizumab administration. Methods Case report and review of the literature. Results The case of a 26-year-old Caucasian woman with RR-MS, who presented with recurrent vaginitis since the initiation of…
Observational prospective study on Lactobacillus plantarum P 17630 in the prevention of vaginal infections, during and after systemic antibiotic ther…
2018
We performed a prospective cohort parallel observational study on the use of Lactobacillus plantarum P 17630 in the prevention of vaginal infections. Eligible were women with a diagnosis of bacterial vaginosis (15 days) and documented history of recurrent vaginal infections; and/or cystitis (15 days); and/or treatment with antibiotics for bacterial respiratory tract infections during the week before the study entry. Study subjects were prescribed Lactobacillus plantarum P 17630 100.000.000 UFC one vaginal capsule per day for 6 days, then a capsule per week for 16 weeks. Eligible subjects were enrolled in two parallel cohorts: 85 women using (group A) and 39 not using (group B) Lactobacillu…
Asymptomatic vaginal herpes simplex virus infections in mice: virology and pathohistology
1996
One of the causes of genital tract infections in humans are herpes simplex virus types 1 and 2 (HSV-1, HSV-2). Although primary and recurrent infections can be clinically apparent and in part very serious, many infections are asymptomatic and result only in temporary genital shedding of virus (recurrences). During our investigations of vaginitis, strain IES of HSV-1 produced an asymptomatic infection. Replication in the murine vaginal (vag.) epithelium as well as antibody formation after vag. infection was comparable to those of survivors after infection with highly virulent strains. Titration of liver, spleen, ovaries, adrenal glands spinal cord, or brain after vag. IES infection revealed …
Pathogenesis of HSV-1/2 induced vaginitis/vulvitis of the mouse: dependence of lesions on genetic properties of the virus and analysis of pathohistol…
1993
A scoring system for herpes simplex virus (HSV) induced vaginitis/vulvitis in Balb/c mice was delineated from vaginal infections. Four degrees of vaginitis/vulvitis could be distinguished after infection with suitable strains of HSV despite nearly identical replication rates. The time course of replication, inflammation and pathohistology was compared further. Grade 0 was defined by lack of symptoms despite presence of strong replication, which was detectable at days 3-6. Focal necrotic lesions of the epithelial layer were present containing HSV-specific antigens. DNA could be detected by hybridization only in the outer zone of these areas. At day 6 these zones began to be re-epithelialized…
Gynecological Disorders in Patients with Non-celiac Wheat Sensitivity
2019
Background: Non-celiac wheat sensitivity (NCWS) most frequently presents clinically with irritable bowel syndrome (IBS)-like symptoms, although many extra-intestinal manifestations have also been attributed to it. No studies to date have evaluated the presence and frequency of gynecological symptoms in NCWS. Aim: To evaluate the frequency of gynecological disorders in patients with NCWS. Patients and Methods: Sixty-eight women with NCWS were included in the study. A questionnaire investigating gynecological symptoms and recurrent cystitis was administered, and patients reporting symptoms were then examined by specialists. Three control groups were selected: 52 patients with IBS not related …
Mixed vaginal infections of Balb/c mice with low virulent herpes simplex type 1 strains result in restoration of virulence properties: vaginitis/vulv…
1997
Vaginal infections of BALB/c Ann mice with herpes simplex virus type 1 (HSV-1) were studied. Mice were inoculated with virulent strains ANG path and 17 syn+ or low-virulent recombinant strains 27/III and 17-syn3 that differ from parental strains in their glycoprotein B (gB) gene sequences. When low-virulent strains were inoculated separately, no vaginitis/vulvitis was produced despite replication in the vagina. In contrast, after coinfection of mice with the two low-virulent strains, vaginitis/vulvitis was produced and virus could be recovered from the central nervous system (CNS). Two of the CNS isolates produced vaginitis/vulvitis, neuroinvasiveness and death of mice after vaginal infecti…
Treatment of Vaginal Trichomoniasis with a Single Dose of Tinidazole
1974
SummaryTwenty-two patients with proven vaginal trichomoniasis were treated with a single dose of 2 g. tinidazole. Twenty-one patients were cured, at both the early and the late follow-up visits. No side-effects were noted and no abnormalities of the clinical laboratory parameters were found in the trial. A historical comparison with published works was carried out and the results compared favourably with those found in the literature for tinidazole as well as for other agents used in a similar fashion.
Localization of latency-associated transcripts in the uterovaginal plexus of herpes simplex virus type 1 and 2 latently infected mice.
1997
The vagina and medulla of the adrenal gland of mice vaginally infected with herpes simplex virus (HSV) types 1 and 2 were examined in the latent stage of infection (5 to 51 weeks post-infection). RNA in situ hybridization with HSV-1 and -2 latency-associated transcript (LAT) RNA probes resulted in positively stained neuronal cell nuclei in the uterovaginal plexus, but not in the medulla of the adrenal gland. These organs were chosen because HSV antigens can be detected not only in the vaginal epithelium, but also in neurons of the uterovaginal plexus and in the medulla of the adrenal gland at the acute stage of genital infection. To our knowledge, this is the first report describing LATs in…
