Efficacy and safety of hydroxychloroquine for treatment of mild SARS-CoV-2 infection and prevention of COVID-19 severity in pregnant and postpartum women: A randomized, double-blind, placebo-controlled trial.

INTRODUCTION: Pregnant women have an increased risk of severe COVID-19. Evaluation of drugs with a safety reproductive toxicity profile is a priority. At the beginning of the pandemic, hydroxychloroquine (HCQ) was recommended for COVID-19 treatment. MATERIAL AND METHODS: A randomized, double-blind, placebo-controlled clinical trial was conducted in eight teaching hospitals in Spain to evaluate the safety and efficacy of HCQ in reducing viral shedding and preventing COVID-19 progression. Pregnant and postpartum women with a positive SARS-CoV-2 PCR (with or without mild COVID-19 signs/symptoms) and a normal electrocardiogram were randomized to receive either HCQ orally (400 mg/day for 3 days and 200 mg/day for 11 days) or placebo. PCR and electrocardiogram were repeated at day 21 after treatment start. Enrollment was stopped before reaching the target sample due to low recruitment rate. Trial registration EudraCT #: 2020-001587-29, on April 2, 2020. CLINICAL TRIALS: gov # NCT04410562, registered on June 1, 2020. RESULTS: A total of 116 women (75 pregnant and 41 post-partum) were enrolled from May 2020 to June 2021. The proportion of women with a positive SARS-CoV-2 PCR at day 21 was lower in the HCQ group (21.8%, 12/55) than in the placebo group (31.6%, 18/57), although the difference was not statistically significant (P = 0.499). No differences were observed in COVID-19 progression, adverse events, median change in QTc, hospital admissions, preeclampsia or poor pregnancy and perinatal outcomes between groups. CONCLUSIONS: HCQ was found to be safe in pregnant and postpartum women with asymptomatic or mild SARS-CoV-2 infection. Although the prevalence of infection was decreased in the HCQ group, the statistical power was insufficient to confirm the potential beneficial effect of HCQ for COVID-19 treatment.

Metabolic impact of current therapeutic strategies in Polycystic Ovary Syndrome: a preliminary study.

PURPOSE: To investigate the metabolic impact of currently used therapies in polycystic ovary syndrome (PCOS). METHODS: This is an observational, retrospective and transversal protocol. A small cohort of 133 patients, aged 14-48 years, diagnosed with PCOS was divided into four experimental groups: 1) untreated PCOS patients (n = 51); 2) PCOS patients treated with one of the following therapies (n = 82): a) combined oral contraceptives (COC, n = 35); b) metformin (n = 11); and c) inositols (n = 36). RESULTS: Although only < 10% of patients included in this cohort can be strictly encompassed in the development of metabolic syndrome, approximately 20% had insulin resistance. In PCOS patients, COC treatment modified the hormonal profile and worsened lipid parameters (increasing cholesterol and triglyceride levels) and insulin resistance, whereas inositol therapies improved significantly insulin resistance and glycosylated hemoglobin, reducing cholesterol and triglyceride levels. In these women, obesity was associated with greater alterations in lipid and glycemic metabolism and with higher blood pressure levels. PCOS patients with phenotype A presented vaster alterations in lipid metabolism and higher values of glycosylated hemoglobin as well as blood pressure compared to other PCOS phenotypes. CONCLUSIONS: Results in this paper suggest that inositol therapies (alone or combined with COC) are the most useful therapies with the best benefits against PCOS symptoms. Thus, integrative treatment may become a more efficient long-term choice to control PCOS symptoms. Furthermore, obesity can be considered as an adverse symptom and calorie restriction a key element of combined treatment in PCOS, not only for fertility management but also in long-term metabolic sequelae.

Hydroxychloroquine efficacy and safety in preventing SARS-CoV-2 infection and COVID-19 disease severity during pregnancy (COVID-Preg): a structured summary of a study protocol for a randomised placebo controlled trial.

OBJECTIVES: The primary objectives of the study are: 1. To assess the effect of hydroxychloroquine (HCQ) in reducing SARS-CoV-2 viral shedding by PCR in infected pregnant women with mild symptoms. 2. To assess the efficacy of HCQ to prevent SARS-CoV-2 infection in pregnant women in contact with an infected or suspected case. 3. To evaluate the effect of HCQ in preventing the development of the COVID-19 disease in asymptomatic SARS-CoV-2-infected pregnant women. The secondary objectives are: 1. To determine the effect of HCQ on the clinical course and duration of the COVID-19 disease in SARS-CoV-2-infected pregnant women. 2. To determine the impact of HCQ on the risk of hospitalization and mortality of SARS-CoV-2-infected pregnant women. 3. To assess the safety and tolerability of HCQ in pregnant women. 4. To describe the clinical presentation of SARS-CoV-2 infection during pregnancy. 5. To describe the effects of maternal SARS-CoV-2 infection on pregnancy and perinatal outcomes by treatment group. 6. To determine the risk of vertical transmission (intra-utero and intra-partum) of SARS-CoV-2. TRIAL DESIGN: Randomized double-blind placebo-controlled two-arm multicentre clinical trial to evaluate the safety and efficacy of HCQ to prevent and/or minimize SARS-CoV-2 infection during pregnancy. Participants will be randomized to receive a 14-day oral treatment course of HCQ or placebo, ratio 1:1. PARTICIPANTS: Study population: pregnant women undergoing routine prenatal follow up or attending emergency units at the participating hospitals who report either symptoms/signs suggestive of COVID-19 disease or close contact with a suspected or confirmed COVID-19 case. Inclusion criteria Women will be invited to participate in the trial and sign an informed consent if they meet the following inclusion criteria. • Presenting with fever (≥37.5°C) and/or one mild symptom suggestive of COVID-19 disease (cough, dyspnoea, chills, odynophagia, diarrhoea, muscle pain, anosmia, dysgeusia, headache) OR being contact* of a SARS-CoV-2 confirmed or suspected case in the past 14 days • More than 12 weeks of gestation (dated by ultrasonography) • Agreement to deliver in the study hospitals Exclusion criteria • Known hypersensitivity to HCQ or other 4-amonoquinoline compounds • History of retinopathy of any aetiology • Concomitant use of digoxin, cyclosporine, cimetidine • Known liver disease • Clinical history of cardiac pathology including known long QT syndrome • Unable to cooperate with the requirements of the study • Participating in other intervention studies • Delivery onset (characterized by painful uterine contractions and variable changes of the cervix, including some degree of effacement and slower progression of dilatation up to 5 cm for first and subsequent labours) The study participants will be stratified by clinical presentation and SARS-CoV-2 PCR results. Assignment of participants to study groups will be as follows: • SARS-CoV-2-PCR confirmed, infected pregnant women: a. symptomatic (n=100) b. asymptomatic (n=100) • SARS-CoV-2 PCR negative pregnant women in contact* with a SARS-CoV-2-infected confirmed or suspected case (n=514). *The ECDC definition of close contact will be followed. The trial will be conducted in five hospitals in Spain: Hospital Clínic of Barcelona, Hospital Sant Joan de Déu and Hospital de la Santa Creu i Sant Pau, in Barcelona, and HM Puerta del Sur and Hospital Universitario de Torrejón, in Madrid. INTERVENTION AND COMPARATOR: Participants will be randomized to HCQ (400 mg/day for three days, followed by 200 mg/day for 11 days) or placebo (2 tablets for three days, followed by one tablet for 11 days). MAIN OUTCOMES: The primary outcome is the number of PCR-confirmed infected pregnant women assessed from collected nasopharyngeal and oropharyngeal swabs at day 21 after treatment start (one week after treatment is completed). RANDOMISATION: Allocation of participants to study arms will be done centrally by the trial's Sponsor (the Barcelona Institute for Global Health, ISGlobal) by block randomization. This method will ensure balanced allocation to both arms. The electronic CRF will automatically assign a study number to each participant, depending on her study group and recruitment site. Each number will be related to a treatment number, which assigns them to one of the study arms. BLINDING (MASKING): Participants, caregivers, investigators and those assessing the outcomes will be blinded to group assignment. Study tablets (HCQ and placebo) will be identically packaged in small opaque bottles. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): This study requires 200 SARS-CoV-2 infected and 514 contact pregnant women, randomised 1:1 with 100 and 227 respectively in each study arm. TRIAL STATUS: Protocol version 1.0, from May 8th, 2020. Recruitment is ongoing (first patient recruited the 19th May 2020 and recruitment end anticipated by December 2020). TRIAL REGISTRATION: EudraCT number: 2020-001587-29, registered 2 April 2020. Clinicaltrials.gov identifier: NCT04410562 , retrospectively registered 1 June 2020. FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol.

Immunogenicity, transplacental transfer of pertussis antibodies and safety following pertussis immunization during pregnancy: Evidence from a randomized, placebo-controlled trial.

BACKGROUND: Pertussis immunization during pregnancy is recommended in many countries. Data from large randomized controlled trials are needed to assess the immunogenicity, reactogenicity and safety of this approach. METHODS: This phase IV, observer-blind, randomized, placebo-controlled, multicenter trial assessed immunogenicity, transplacental transfer of maternal pertussis antibodies, reactogenicity and safety of a reduced-antigen-content diphtheria-tetanus-three-component acellular pertussis vaccine (Tdap) during pregnancy. Women received Tdap or placebo at 27-36 weeks' gestation with crossover ≤ 72-hour-postpartum immunization. Immune responses were assessed before the pregnancy dose and 1 month after, and from the umbilical cord at delivery. Superiority (primary objective) was reached if the lower limits of the 95% confidence intervals (CIs) of the pertussis geometric mean concentration (GMC) ratios (Tdap/control) in cord blood were ≥ 1.5. Solicited and unsolicited adverse events (AEs) and pregnancy-/neonate-related AEs of interest were recorded. RESULTS: 687 pregnant women were vaccinated (Tdap: N = 341 control: N = 346). Superiority of the pertussis immune response (maternally transferred pertussis antibodies in cord blood) was demonstrated by the GMC ratios (Tdap/control): 16.1 (95% CI: 13.5-19.2) for anti-filamentous hemagglutinin, 20.7 (15.9-26.9) for anti-pertactin and 8.5 (7.0-10.2) for anti-pertussis toxoid. Rates of pregnancy-/neonate-related AEs of interest, solicited general and unsolicited AEs were similar between groups. None of the serious AEs reported throughout the study were considered related to maternal Tdap vaccination. CONCLUSIONS: Tdap vaccination during pregnancy resulted in high levels of pertussis antibodies in cord blood, was well tolerated and had an acceptable safety profile. This supports the recommendation of Tdap vaccination during pregnancy to prevent early-infant pertussis disease. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov: NCT02377349.

Un estudio sobre la utilidad de biomarcadores en infecciones ginecológicas / A study on the utility of biomarkers in gynecological infections

Objetivo: en este estudio se ha querido demostrar que dos biomarcadores ampliamente usados en el diagnóstico de patología infecciosa como son la leucocitosis y la proteína creactiva, también son útiles en la enfermedad inflamatoria pélvica ya que nos permiten establecer la gravedad de cada infección y comprobar la evolución de cada paciente una vez instaurado el tratamiento antibiótico. Método: se hizo un estudio analítico y retrospectivo de 26 pacientes con enfermedad inflamatoria pélvica ingresadas en el Hospital Madrid Monteprincipe, Hospital Madrid Sanchinarro y Hospital Madrid Torrelodones entre los años 2008 y 2012 y se analizaron los valores de ambos marcadores obtenidos en las analíticas de urgencias al ingreso y en las últimas antes del alta. Se realizó un test T de Student para muestras apareadas para leucocitosis (p = 0,000) y para proteína creactiva (p = 0,002), con diferencias estadísticamente significativas (p < 0,05) en ambos. Conclusión: tanto la leucocitosis como la proteína creactiva son útiles también como reflejo cuantitativo de la gravedad de la enfermedad inflamatoria pélvica y como indicador de respuesta al tratamiento (AU)

Objective: In this study we wanted to demonstrate that two biomarkers widely used in infectious pathology such as leukocytosis and C-reactive protein are also viable in pelvic inflamatory disease to quantify the severity of the infection and evaluate the response of each patient once the antibiotic treatment has been established. Method: We performed a retrospective analytical study of 26 patients with pelvic inflamatory disease admitted in Hospital Madrid Montepríncipe, Hospital Madrid Sanchinarro and Hospital Madrid Torrelodones between the years 2008 and 2012, and analyzed the values of both markers obtained before the admittance and in the latest tests before the discharge. Apaired samples T-Student test was performed for Leucocitosis (p = 0.000) and C-reactive protein (p = 0.002), with significant differences (p < 0.05). Conclusion: Both the leukocytosis and C-reactive protein are useful as a quantitative reflection of the severity of pelvic inflamatory disease and also as an indicator of the response to treatment (AU)
