Does the maternal-fetal transmission of SARS-CoV-2 occur during pregnancy?

BACKGROUND AND OBJETIVE: On January 7th, 2020, a new coronavirus, SARS-CoV-2, was identified, as responsible for a new human disease: COVID-19. Given its recent appearance, our current knowledge about the possible influence that this disease can exert on pregnancy is very limited. One of the unknowns to be solved is whether there is a vertical transmission of the infection during pregnancy. PATIENTS AND METHODS: Using the Real-time Polymerase Chain Reaction techniques for SARS-CoV-2 nucleic acids, the possible presence of this germ in vaginal discharge and amniotic fluid was investigated in four pregnant Caucasian patients affected by mild acute symptoms of COVID-19 during the second trimester of pregnancy. RESULTS: There is no laboratory evidence to suggest a possible passage of SARS-CoV-2 from the infected mother to the amniotic fluid. CONCLUSIONS: It is necessary to expand the investigation of COVID-19 cases diagnosed during pregnancy to clarify the real influence that SARS-CoV-2 has on pregnant women and their offspring, as well as those factors that modulate the disease.

High Risk Human Papilloma Virus Genotypes in Kurdistan Region in Patients with Vaginal Discharge.

BACKGROUND: The human papilloma virus (HPV) is considered as the major risk factor for the development of cervical cancer. This virus is of different genotypes and generally can be classified into high and low risk types. OBJECTIVE: To determine the rate of high risk HPV genotypes in women with vaginal discharge and lower abdominal pain in Kurdistan region, Iraq. MATERIALS AND METHODS: Cervical swabs were taken from 104 women. DNA was extracted and the polymerase chain reaction (PCR) technique was used to determine the presence of high risk genotypes. RESULTS: It was found that 13/104 (12.5%) of the samples were positive for high risk HPV genotypes. Amongst those who were positive, 4/13 (30.7%) were typed as genotype 16 and 7/13 (53.8%) showed mixed genotyping. On the other hand, genotypes 53 and 56 were found in only one sample each. CONCLUSIONS: High risk HPV genotypes are not uncommon and further community based study is needed to determine the prevalence of HPV and its genotypes and plan for prevention of infection.

Evaluating Quality of Care for Sexually Transmitted Infections in Different Clinical Settings.

BACKGROUND: We examined quality of care across different clinical settings within a large safety-net hospital in Massachusetts for patients presenting with penile discharge/dysuria or vaginal discharge. METHODS: Using a modified Delphi approach, a list of sex-specific sexually transmitted infection (STI) quality measures, covering 7 domains of clinical care (history, examination, laboratory testing, assessment, treatment, additional screening, counseling), was selected as standard of care by a panel of 5 STI experts representing emergency department (ED), obstetrics/gynecology (Ob/Gyn), family medicine (FM), primary care (PC), and infectious disease. Final measures were piloted with 50 charts per sex from the STI Clinic and age, sex, and visit date-matched charts from PC, FM, ED, and Ob/Gyn. Performance was scored as compliance among individual measures within 7 domains, standardized to add up to one to adjust for variable number of measures per domain, with an overall score of 7 indicating complete adherence to standards. RESULTS: Expert review process took 2 weeks and resulted in 24 and 34 final measures for male and female patients, respectively. Performance on 7 clinical domains ranged from 3.16 to 4.36 for male patients and 3.17 to 4.33 for female patients. Sexually transmitted infection clinic seemed to score higher on laboratory testing, additional screening, and counseling, but lower on examination and assessment, and ED seemed to score higher on examination and treatment, PC and FM on laboratory testing for male patients and on examination and treatment for female patients, and Ob/Gyn on treatment. CONCLUSIONS: An instrument to discern standard of care and identify strengths and weaknesses in specific domains of clinical documentation for patients presenting with STI complaints can be developed and implemented for quality evaluation across care settings. Further research is needed on whether these findings can be integrated into site-specific quality improvement processes and linked to cost analyses.

Symptomatic vaginal discharge is a poor predictor of sexually transmitted infections and genital tract inflammation in high-risk women in South Africa.

BACKGROUND: Diagnosis and treatment of sexually transmitted infections (STIs) is a public health priority, particularly in regions where the incidence of human immunodeficiency virus (HIV) infection is high. In most developing countries, STIs are managed syndromically. We assessed the adequacy of syndromic diagnosis of STIs, compared with laboratory diagnosis of STIs, and evaluated the association between STI diagnosis and the risk of HIV acquisition in a cohort of high-risk women. METHODS: HIV-uninfected high-risk women (n = 242) were followed for 24 months. Symptoms of STIs were recorded, and laboratory diagnosis of common STI pathogens was conducted every 6 months. Forty-two cytokines were measured by Luminex in cervicovaginal lavage specimens at enrollment. Human immunodeficiency virus type 1 (HIV-1) infection was evaluated monthly. RESULTS: Only 12.3% of women (25 of 204) who had a laboratory-diagnosed, discharge-causing STI had clinically evident discharge. Vaginal discharge was thus a poor predictor of laboratory-diagnosed STIs (sensitivity, 12.3%; specificity, 93.8%). Cervicovaginal cytokine concentrations did not differ between women with asymptomatic STIs and those with symptomatic STIs and were elevated in women with asymptomatic STIs, compared with women with no STIs or bacterial vaginosis. Although laboratory-diagnosed STIs were associated with increased risk of HIV infection (hazard ratio, 3.3 [95% confidence interval, 1.5-7.2)], clinical symptoms were not. CONCLUSIONS: Syndromic STI diagnosis dependent on vaginal discharge was poorly predictive of laboratory-diagnosed STI. Laboratory-diagnosed STIs were associated with increased susceptibility to HIV acquisition, while vaginal discharge was not.

Postpartum endometritis caused by herpes and cytomegaloviruses.

BACKGROUND: Postpartum endometritis is usually a polymicrobial infection caused by organisms that are part of the normal vaginal flora. A pathologically confirmed case of postpartum endometritis secondary to herpes and cytomegalovirus in a human immunodeficiency virus (HIV)-positive patient is reported. CASE: A 29-year-old, HIV-positive woman presented 6 days postpartum with abdominal pain and foul-smelling vaginal discharge. Pelvic ultrasonography revealed retained products of conception. Dilation and evacuation was performed, and antibiotics were started. Despite adequate antibiotics and laparoscopic drainage of a pelvic collection, fevers and pain continued. A total abdominal hysterectomy, salpingectomy, and appendectomy were performed. Pathology reported herpes and cytomegalovirus infection of the uterus. CONCLUSION: Herpes simplex virus (HSV) and cytomegalovirus need to be considered as a potential cause of postpartum endometritis. When antibiotic therapy fails, an antiviral regimen should be considered.

Treatment-seeking behavior for sexually transmitted infections in a high-risk population.

The World Health Organization estimates that 340 million new cases of curable sexually transmitted infections (STIs) occur every year, while 33 million individuals are estimated to be living with HIV. The AIDS and STI epidemics are not independent with untreated STIs increasing HIV acquisition and transmission. Female sex workers have increased prevalence of untreated STIs and have been hypothesized to affect the health and HIV incidence of the general population. This paper aims to investigate why some female sex workers who experience symptoms of vaginal discharge or genital ulcers seek treatment while others do not. Data were collected from a cohort study conducted between 2002 and 2005 among female bar and hotel workers in Moshi, Tanzania. Study subjects were recruited from 7 out of 15 administrative wards in Moshi as part of the Moshi's Women's Health Project. Data were restricted to women self-reporting symptoms of vaginal discharge or genital ulcers (n=459) within the past year. Logistic regression was performed with SAS 9.1. Qualitative analysis was performed using in-depth interviews and focus group discussions among a convenience sample (n=42) of women already enrolled in the study. All interviews and focus group discussions were tape-recorded and transcribed, and data were analyzed thematically. Sixty-four percent of the sample sought treatment for either ailment. Multivariate analysis identified relationship to man of last sexual intercourse, ever experiencing a pregnancy, and age as significant predictors to seeking treatment. Four salient themes of threats to fertility, stigma correlated with prostitution, discomfort with the physical exam, and perceived views of clients were revealed as predictors to why women seek or intentionally ignore symptoms. Understanding the motivations and barriers for seeking treatment of STIs has far ranging public health implications that could help curtail the unnecessary associated morbidity and mortality and curtail the transmission of HIV.

Evaluation of common organisms causing vaginal discharge.

BACKGROUND: Vaginal discharge is very common problem among females. Alteration in balance of normal vaginal organisms can cause the overgrowth of the bacteria that creates vaginal discharge. It is common among sexually active women yet there still remain gaps in our knowledge of this infectious disorder. OBJECTIVE: To evaluate the frequency of bacterial vaginosis (BV), vaginal candidiasis (VC), vaginal trichomoniasis and Group B streptococcus in women complaining of vaginal discharge in our setup. METHOD: A total of 100 women of reproductive age group with the complaint of vaginal discharge were included in the study. After filling proforma patients were examined by speculum examination and two high vaginal swabs (HVS) were collected aseptically from each patient. One swab was used for making wet mount for clue cells, pus cells and for motility of Trichomonas vaginalis. The other swab was used to check pH and Amine test. The growth was confirmed by Gram staining in each case. RESULTS: Gardnerrella vaginalis were isolated in 28%, Group B streptococcus in 5% and T. vaginolis in 4% of women. CONCLUSION: Gardnerella vaginalis causing BV is the most common cause of vaginal discharge in otherwise healthy women of reproductive age group in our setup.

Prevalence of HIV among women with vaginal discharge in a gynecological clinic.

OBJECTIVE: Vaginal discharge is a common complaint among women with sexually transmitted diseases (STDs) in Nigeria. Given the association between STDs and HIV and the alarming rise in the prevalence of HIV in Nigeria, we performed this study to determine the prevalence of HIV in patients with vaginal discharge. STUDY DESIGN: Between April 2000 and August 2000, women who attended the Lagos University Teaching Hospital and complained of vaginal discharge were adequately counseled for HIV serotest. High vaginal/endocervical swabs and venous blood were taken for microbiological studies and HIV serotest, respectively. RESULTS: Out of the 230 women counseled for HIV serotest 140 (60.9%) consented. The mean age of the 140 was 31.1+/-6.9 years (range 18-50 years). In 31 (22.1%), Candida albicans was isolated, in 26 Gardnerella vaginalis (18.8%), in 17 Staphylococcal spp. (12.1%); and E. coli, Trichomonas vaginalis, and Neisseria gonococcus in 7.9%, 4.3%, and 1.4%, respectively. Four (2.9%) of the 140 patients were HIV seropositive, and all had Candida albicans isolated. The prevalence of HIV among patients with Candida albicans was 12.9%. Association between HIV seropositivity and Candida albicans infection is significant (X2=14.48; p=0.002). CONCLUSION: Candida albicans is a common cause of vaginal discharge among HIV-seropositive women in Lagos.

Variation in virological parameters and antibody responses in macaques after atraumatic vaginal exposure to a pathogenic primary isolate of SIVmac251.

We developed an animal model for the male-to-female transmission of human immunodeficiency virus, consisting of an atraumatic vaginal application of simian immunodeficiency virus onto the intact vaginal mucosa of cynomolgus macaques. Different doses of a pathogenic isolate of SIVmac251, with or without seminal plasma, were infused into the vaginas of female macaques. Infection of macaques could be achieved after a single exposure to the virus. Two patterns of infection were underscored with no relation to the virus dose inoculated: in 50% of the monkeys, SIV was persistently recovered and a strong antibody response to SIV was evidenced in blood and vaginal secretions. In the other infected animals, SIV infection was only transiently evidenced and a weak systemic antibody response was detected. It appeared that the presence of seminal plasma may be implicated in this variability only when low doses of virus are inoculated. Sequence analysis of the env gene of SIV revealed that most of the persistently viraemic animals were infected with a viral variant different from that of transiently viraemic macaques.

Genital shedding of human immunodeficiency virus type 1 DNA during pregnancy: association with immunosuppression, abnormal cervical or vaginal discharge, and severe vitamin A deficiency.

The presence of human immunodeficiency virus type 1 (HIV-1) in genital secretions may be a determinant of vertical HIV-1 transmission. Cervical and vaginal secretions from HIV-1-seropositive pregnant women were evaluated to determine prevalence and correlates of HIV-1-infected cells in the genital tract. HIV-1 DNA was detected by polymerase chain reaction in 32% of 212 cervical and 10% of 215 vaginal specimens. Presence of HIV-1 DNA in the cervix was associated with cervical mucopus and a significantly lower absolute CD4 cell count (354 vs. 469, P < .001). An absolute CD4 cell count <200 was associated with a 9.6-fold increased odds of cervical HIV-1 DNA detection compared with a count > or = 500 (95% confidence interval, 2.8-34.2). Detection of vaginal HIV- 1 DNA was associated with abnormal vaginal discharge, lower absolute CD4 cell count, and severe vitamin A deficiency. Presence of HIV-1-infected cells in genital secretions was associated with immunosuppression and abnormal cervical or vaginal discharge.
