Clinical symptoms of hyperandrogenic women diagnosed with COVID‐19

The correlation between humoral immune responses and severity of clinical symptoms in COVID-19 patients

The SARS-CoV-2 pandemic persists with global repercussions. Initial COVID-19 symptoms encompass pneumonia, fever, myalgia, and fatigue. The human immune system produces IgM and IgG antibodies in response to SARS-CoV-2. Despite previous research, a comprehensive understanding of the interplay between clinical manifestations and humoral immune responses remains elusive. This study aims to scrutinize this association. 134 COVID-19 patients were enrolled, and stratified into mild, moderate, and severe symptom groups. Serum IgM and IgG levels were assessed thrice at one-month intervals using ELISA. The findings reveal significant elevation in serum IgG levels in moderate compared to mild cases (P < 0.001). Additionally, IgG production was significantly heightened in severe cases compared to both mild (P < 0.0001) and moderate (P < 0.05) groups. IgM and IgG levels peaked initially and diminished over time. While anti-SARS-CoV-2 antibodies are expected to confer protection, the direct correlation between IgG levels and symptom severity may arise from delayed immune activation, resulting in an intense antibody response in severe cases. Given evidence linking delayed immune function with a dysregulated innate immune response, comprehensive data collection should encompass not only serum IgG and IgM, but also early measurement of type I interferons at symptom onset. This could provide a more thorough understanding of COVID-19 progression.

Serum testosterone mirrors inflammation parameters in females hospitalized with COVID-19

BACKGROUND

While low testosterone (T) was described as a predictor of unfavorable coronavirus-disease 19 (COVID-19) outcome in men, data concerning the role of T in women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are scant and limited to small cohorts. This study investigated the relationship between serum T values and outcomes of COVID-19 in a large female hospitalized cohort.

METHODS

One-hundred-sixty-eight adult women (median age 77, range 18-100 years; 154 in post-menopause) hospitalized for COVID-19 were assessed for PaO2/Fio2 ratio, serum T and inflammatory parameters.

RESULTS

Median duration for hospital stay was 14.2 days (range 1-115) with overall mortality of 26% (n = 44). Subjects who died were significantly older (p < 0.001), had significantly more comorbidities (p = 0.015) and higher serum T (p = 0.040), white blood cells (p = 0.007), c-reactive protein (CRP; p < 0.001), interleukin-6 (IL-6; p < 0.001), procalcitonin (PCT; p < 0.001), lactate dehydrogenase (LDH; p = 0.001), D-dimer (p = 0.035), fibrinogen (p = 0.038) and lower serum free-triiodothyronine (FT3; p < 0.001) and luteinizing hormone (LH; p = 0.024) values. In post-menopausal women, significant associations were observed between T levels and serum CRP (rho: 0.23; p = 0.002), IL-6 (rho: 0.41; p < 0.001), LDH (rho: 0.34; p < 0.001), D-Dimer (rho: 0.21; p = 0.008), PCT (rho: 0.26; p = 0.001) and HDL cholesterol (rho:  - 0,22, p = 0.008). In multivariate regression analyses, serum T maintained the significant association with mortality after correction for age, coexistent comorbidities and serum LH and FT3, whereas it was lost after correction for inflammatory parameters.

CONCLUSION

In females, high serum T levels might be a mirror of inflammatory phenotype and worse COVID-19 course.

Association of androgenetic alopecia with a more severe form of COVID-19 infection

BACKGROUND

Individual susceptibility to develop acute respiratory distress syndrome is related to age and most frequent comorbidities. So far, it is known that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily infects the type II pneumocytes in humans, with the help of transmembrane serine protease type 2 (TMPRSS2). Up to now, the only known transcriptional promoters of genes coding TMPRSS2 are androgenic. Theoretically, the elevated level of androgens or androgen receptors would lead to a higher expression of TMPRSS2 and a higher level of viremia as a consequence.

AIM

The aim of our research was to indirectly investigate if the severity of SARS-CoV-2 infection is dependent on the expression of androgen receptors.

METHODS

This observational study analysed male patients hospitalized for SARS-CoV-2 infection with respect to the length of hospitalisation, the outcome of the disease, the type of necessary oxygen support and the presence of comorbidities and hairiness. In hairiness estimation, we used an adapted version of the Hamilton-Norwood scale and the presence of the Gabrin sign.

RESULTS

In total, 208 patients were enrolled in the study. There were statistically significant differences comparing the average age of patients with the different types of alopecia when groups were divided according to the presence of the Gabrin sign (t = 4.958, p > 0.01). The outcomes and the type of needed minimal oxygen support, compared with the type of alopecia in the case of Gabrin + / - classification showed a statistically significant difference in the outcome of the disease (p = 0.027). There were no statistically significant differences in the distribution of comorbidities among alopecia groups, but hypertension was related to poor COVID-19 prognosis.

CONCLUSION

Our findings suggest that the Gabrin sign and hypertension are related to a poor COVID-19 prognosis.

Androgens' Role in Severity and Mortality Rates of COVID-19

By the end of December 2019 new corona virus began to spread from Wuhan, China and caused a worldwide pandemic. COVID-19 deaths and prevalence represented sex discrepant patterns with higher rate of deaths and infection in males than females which could be justified by androgen-mediated mechanisms. This review aimed to assess the role of androgens in COVID-19 severity and mortality. Androgens increase expressions of Type II transmembrane Serine Protease (TMPRSS2) and Angiotensin Converting Enzyme 2 (ACE2), which both facilitate new corona virus entry into host cell and their expression is higher in young males than females. According to observational studies, prevalence of COVID-19 infections and deaths was more in androgenic alopecic patients than patients without androgenic alopecia. The COVID-19 mortality rates in aged men (>60 years) were substantially higher than aged females and even young males caused by high inflammatory activities such as cytokine storm due to hypogonadism in this population. Use of anti-androgen and TMPRSS2 inhibitor drugs considerably modified COVID-19 symptoms. Androgen deprivation therapy also improved COVID-19 symptoms in prostate cancer: overall the role of androgens in severity of COVID-19 and its associated mortality seemed to be very important. So, more studies in variety of populations are required to define the absolute role of androgens.

Androgens and COVID-19

Background

The humans have been disproportionately affected by the coronavirus disease (COVID‐19) pandemic. The novel coronavirus or the severe acute respiratory syndrome coronavirus 2 (SARS‐COV2) causing coronavirus disease (COVID‐19) has spread across the globe. Androgens have been suggested to have a role in COVID‐19 pathogenesis.

Objective

The objective of this review article is to study the link between androgens and COVID‐19.

Methodology

PubMed and Google Scholar search was performed to retrieve literature related to the topic. Review articles, clinical trials, retrospective studies, observational studies, and case–control studies were considered for the review.

Results

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infected men are more inclined to be hospitalized for intensive care unit (ICU) as compared with women. This difference in the ICU admissions provides some clue for possible influence of androgens in the severity of COVID‐19. The contribution of androgen and androgen receptor in COVID‐19 disease and its severity, as well as the numerous medications targeting androgen and its receptor for lowering COVID‐19 disease severity, are discussed in this review. Available literature suggests the role of androgen in the pathogenesis and severity of COVID‐19. Sensitivity for androgen may be an important factor in regulating the severity of COVID‐19 disease.

Conclusion

There is a scope for the development of COVID‐19 treatments based on androgen suppression. Clinical trials may furnish pivotal data and add more evidence‐based options for the management of COVID‐19.

Polycystic ovary syndrome and risks for COVID-19 infection: A comprehensive review : PCOS and COVID-19 relationship

This comprehensive review aimed to evaluate the relationship between SARS-CoV-2 infection (the cause of coronavirus disease 2019, or COVID-19) and the metabolic and endocrine characteristics frequently found in women with polycystic ovary syndrome (PCOS). In the general population, COVID-19 is more severe in subjects with dyslipidemia, obesity, diabetes mellitus, and arterial hypertension. Because these conditions are comorbidities commonly associated with PCOS, it was hypothesized that women with PCOS would be at higher risk for acquiring COVID-19 and developing more severe clinical presentations. This hypothesis was confirmed in several epidemiological studies. The present review shows that women with PCOS are at 28%-50% higher risk of being infected with the SARS-CoV-2 virus at all ages and that, in these women, COVID-19 is associated with increased rates of hospitalization, morbidity, and mortality. We summarize the mechanisms of the higher risk of COVID-19 infection in women with PCOS, particularly in those with carbohydrate and lipid abnormal metabolism, hyperandrogenism, and central obesity.

"MATH+" Multi-Modal Hospital Treatment Protocol for COVID-19 Infection: Clinical and Scientific Rationale

In December 2019, coronavirus disease 2019 (COVID-19), a severe respiratory illness caused by the new coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China. The greatest impact that COVID-19 had was on intensive care units (ICUs), given that approximately 20% of hospitalized cases developed acute respiratory failure (ARF) requiring ICU admission. Based on the assumption that COVID-19 represented a viral pneumonia and no anti-coronaviral therapy existed, nearly all national and international health care societies recommended "supportive care only" avoiding other therapies outside of randomized controlled trials, with a specific prohibition against the use of corticosteroids in treatment. However, early studies of COVID-19-associated ARF reported inexplicably high mortality rates, with frequent prolonged durations of mechanical ventilation (MV), even from centers expert in such supportive care strategies. These reports led the authors to form a clinical expert panel called the Front-Line COVID-19 Critical Care Alliance (www.flccc.net). The panel collaboratively reviewed the emerging clinical, radiographic, and pathological reports of COVID-19 while initiating multiple discussions among a wide clinical network of front-line clinical ICU experts from initial outbreak areas in China, Italy, and New York. Based on the shared early impressions of "what was working and what wasn't working", the increasing medical journal publications and the rapidly accumulating personal clinical experiences with COVID-19 patients, a treatment protocol was created for the hospitalized patients based on the core therapies of methylprednisolone, ascorbic acid, thiamine, heparin and non-antiviral co-interventions (MATH+). This manuscript reviews the scientific and clinical rationale behind MATH+ based on published in-vitro, pre-clinical, and clinical data in support of each medicine, with a special emphasis of studies supporting their use in the treatment of patients with viral syndromes and COVID-19 specifically.

Androgens in SARS-CoV-2 coronavirus infections

Recent molecular biology findings have shown that for the penetration of the SARS-CoV-2 coronavirus into host cells, a key role is played by protease serine 2, the activity of which is dependent on androgens. The important role of androgens is also evidenced by clinical observations that men in some age categories are infected by this novel coronavirus up to two times more frequently than women. In addition, men with androgenic alopecia tend to have more serious clinical courses, while men with androgen deprivation as a result of prostate cancer treatments tend to have milder courses. This is in line with the fact that preadolescent children are only rarely sickened with serious forms of SARS-CoV-2 infections. Even though these observations may be explained by other factors, many authors have hypothesized that lowered androgen levels and blocking their activity using anti-androgen medication may moderate the course of the viral infection in intermediately- to critically-affected cases. Clearly, it would be important for androgen deprivation to block not just gonadal androgens, but also adrenal androgens. On the other hand, low androgen levels are considered to be a risk factor for the course of SARS-CoV-2 infections, either because low androgen levels have a general effect on anabolic-catabolic equilibrium and energy metabolism, or because of the ability of testosterone to modify the immune system. It is not yet clear if infection with this novel coronavirus might induce hypogonadism, leading to undesirable side effects on male fertility.

Final Results of a Randomized, Placebo-Controlled, Two-Arm, Parallel Clinical Trial of Proxalutamide for Hospitalized COVID-19 Patients: A Multiregional, Joint Analysis of the Proxa-Rescue AndroCoV Trial

Background The role of androgens on COVID-19 is well established. Proxalutamide is a second-generation, non-steroidal antiandrogen (NSAA) with the highest antiandrogen potency among NSAAs and concurrent regulation of angiotensin-converting enzyme 2 (ACE2) expression and inflammatory response. Proxalutamide has been demonstrated to be effective to prevent hospitalizations in early COVID-19 in randomized clinical trials (RCTs). Conversely, in hospitalized COVID-19 patients, preliminary results from two different arms of an RCT (The Proxa-Rescue AndroCoV Trial) also demonstrated a reduction in all-cause mortality. This study aims to report the final, joint results of the two arms (North arm and South arm) of the Proxa-Rescue AndroCoV trial of the two arms (North and South arms) combined, and to evaluate whether COVID-19 response to proxalutamide was consistent across different regions (Northern Brazil and Southern Brazil). Materials and methods Upon randomization, hospitalized COVID-19 patients received either proxalutamide 300mg/day or placebo for 14 days, in addition to usual care, in a proxalutamide:placebo ratio of 1:1 in the North arm and 4:1 in the South arm (ratio was modified due to preliminary report of high drug efficacy). Datasets of the South and North arms were combined, and statistical analysis was performed for the overall study population. Proxalutamide was compared to placebo group for 14-day and 28-day recovery (discharge alive from the hospital) and mortality rates, and overall and post-randomization hospitalization stay. Results of proxalutamide and placebo groups were also compared between the North and South arms. Analysis was also performed stratified by sex and baseline WHO COVID Ordinary Score. Results A total of 778 subjects were included (645 from the North, 317 from the proxalutamide group and 328 from the placebo group; 133 from the South arm, 106 from the proxalutamide group and 27 from the placebo group). Recovery rate was 121% higher in proxalutamide than placebo group at day 14 [81.1% vs 36.6%; Recovery ratio (RecR) 2.21; 95% confidence interval (95% CI), 1.92-2.56; p<0.0001], and 81% higher at day 28 (98.1% vs 47.6%; RecR, 1.81; 95% CI, 1.61-2.03; p<0.0001). All-cause mortality rate was 80% lower in proxalutamide than placebo group at Day 14 [8.0% vs 39.2%; Risk ratio (RR), 0.20; 95% CI, 0.14-0.29; p<0.0001], and 78% lower at Day 28 (10.6% vs 48.2%; RR, 0.22; 95% CI 0.16-0.30). Post-randomization time-to-discharge was shorter in proxalutamide [median, 5 days; interquartile range (IQR), 3-8] than placebo group (median, 9 days; IQR, 6-14) (p<0.0001). Results were statistically similar between North and South arms for all measured outcomes. Males and females presented similar results in all outcomes. Patients that did not require oxygen use (scores 3 and 4) did not present statistically significant improvement in recovery and mortality rates, whereas scores 5 and 6 presented significant improvements in all outcomes (p<0.0001 for all). Conclusion Proxalutamide increased recovery rate, reduced mortality rate and shortened hospital stay in hospitalized COVID-19 patients. Results were similar between the two different arms, providing further consistency for the efficacy of proxalutamide when used in late-stage COVID-19.

Vitamin D association with the renin angiotensin system in polycystic ovary syndrome

Vitamin D deficiency is a negative endocrine renin-angiotensin system (RAS) modulator and PCOS women are often vitamin D deficient, leading to RAS overactivation in PCOS. A cross-sectional study was performed in 99 PCOS and 68 control women who presented sequentially. Circulating plasma levels of RAS proteins (Angiotensin-converting enzyme 2 (ACE2), renin and angiotensinogen) were measured by Slow Off-rate Modified Aptamer (SOMA)-scan and 25-hydroxyvitamin D [25(OH)D] was measured by tandem mass spectroscopy. The RAS system was found to be overactivated in the PCOS women compared to non-PCOS control women with increased renin and decreased angiotensinogen (p < 0.05); 25-hydroxyvitamin D was also significantly lower in the PCOS group (p < 0.0001). In PCOS women, plasma renin was increased in vitamin D deficient and insufficient groups compared with the vitamin D sufficient group (p < 0.005), but did not differ across non-PCOS control subgroups. In non-PCOS controls, plasma ACE2 decreased from vitamin D insufficiency to deficiency (p < 0.05). Angiotensinogen was not different across the vitamin D sufficiency, insufficiency and deficiency strata for either PCOS or non-PCOS controls. These data show that RAS activation through increased plasma renin levels was seen in vitamin D insufficient and deficient PCOS subjects compared to non-PCOS control women. In addition, decreased plasma ACE2 levels were seen in vitamin D deficiency in non-PCOS controls, which may predispose these vitamin D deficient subjects to increased cardiovascular risk and susceptibility to infectious agents such as COVID-19 where this is a risk factor.

Cardiac and Renal SARS-CoV-2 Viral Entry Protein Regulation by Androgens and Diet: Implications for Polycystic Ovary Syndrome and COVID-19

The susceptibility and the severity of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are associated with hyperandrogenism, obesity, and preexisting pulmonary, metabolic, renal, and cardiac conditions. Polycystic ovary syndrome (PCOS), the most common endocrine disorder in premenopausal women, is associated with obesity, hyperandrogenism, and cardiometabolic dysregulations. We analyzed cardiac, renal, circulatory, and urinary SARS-CoV-2 viral entry proteins (ACE2, TMPRSS2, TMPRSS4, furin, cathepsin L, and ADAM17) and androgen receptor (AR) expression, in a peripubertal androgen exposure model of PCOS. Peripubertal female mice were treated with dihydrotestosterone (DHT) and low (LFD) or high (HFD) fat diet for 90 days. HFD exacerbated DHT-induced increase in body weight, fat mass, and cardiac and renal hypertrophy. In the heart, DHT upregulated AR protein in both LFD and HFD, ACE2 in HFD, and ADAM17 in LFD. In the kidney, AR protein expression was upregulated by both DHT and HFD. Moreover, ACE2 and ADAM17 were upregulated by DHT in both diets. Renal TMPRSS2, furin, and cathepsin L were upregulated by DHT and differentially modulated by the diet. DHT upregulated urinary ACE2 in both diets, while neither treatment modified serum ACE2. Renal AR mRNA expression positively correlated with Ace2, Tmprss2, furin, cathepsin L, and ADAM17. Our findings suggest that women with PCOS could be a population with a high risk of COVID-19-associated cardiac and renal complications. Furthermore, our study suggests that weight loss by lifestyle modifications (i.e., diet) could potentially mitigate COVID-19-associated deleterious cardiorenal outcomes in women with PCOS.

Early COVID-19 therapy with azithromycin plus nitazoxanide, ivermectin or hydroxychloroquine in outpatient settings significantly improved COVID-19 outcomes compared to known outcomes in untreated patients

In a prospective observational study (pre-AndroCoV Trial), the use of nitazoxanide, ivermectin and hydroxychloroquine demonstrated unexpected improvements in COVID-19 outcomes when compared to untreated patients. The apparent yet likely positive results raised ethical concerns on the employment of further full placebo controlled studies in early-stage COVID-19. The present analysis aimed to elucidate, through a comparative analysis with two control groups, whether full placebo-control randomized clinical trials (RCTs) on early-stage COVID-19 are still ethically acceptable. The Active group (AG) consisted of patients enrolled in the Pre-AndroCoV-Trial (n = 585). Control Group 1 (CG1) consisted of a retrospectively obtained group of untreated patients of the same population (n = 137), and Control Group 2 (CG2) resulted from a precise prediction of clinical outcomes based on a thorough and structured review of indexed articles and official statements. Patients were matched for sex, age, comorbidities and disease severity at baseline. Compared to CG1 and CG2, AG showed reduction of 31.5-36.5% in viral shedding (p < 0.0001), 70-85% in disease duration (p < 0.0001), and 100% in respiratory complications, hospitalization, mechanical ventilation, deaths and post-COVID manifestations (p < 0.0001 for all). For every 1000 confirmed cases for COVID-19, at least 70 hospitalizations, 50 mechanical ventilations and five deaths were prevented. Benefits from the combination of early COVID-19 detection and early pharmacological approaches were consistent and overwhelming when compared to untreated groups, which, together with the well-established safety profile of the drug combinations tested in the Pre-AndroCoV Trial, precluded our study from continuing employing full placebo in early COVID-19.

A Comprehensive Review of the Management of Pregnant Women with COVID-19: Useful Information for Obstetricians

Due to the physiological changes of the cardiovascular system and respiratory system in pregnancy, pregnant women are vulnerable to pathogen infection and severe pneumonia. With the increasing incidence of COVID-19 pneumonia, its influence on pregnant women and neonates has attracted more attention. In this review, we collected all relevant articles published in English from September 1, 2019 to June 10, 2021, regarding the epidemiology, clinical presentations, chemical examinations, imaging findings, the timing of delivery and delivery mode, maternal and neonatal complications, medication, and vertical transmission of COVID-19 in pregnancy. It has been reported that compared with non-pregnant females, pregnant women with COVID-19 are more likely to develop into severe type. In particular, the risk of entering the intensive care unit and endotracheal intubation was higher. Chest computed tomography and blood routine examination are useful for the diagnosis of COVID-19 in a short period of time. COVID-19 pneumonia is not an independent indication for terminating the pregnancy, and it is not contraindicated for vaginal delivery. Compared to normal pregnant females, patients with COVID-19 showed an elevated susceptibility of preterm delivery. Multidisciplinary consultation was suggested in the treatment policy of COVID-19 in pregnancy. Currently, there is no evaluation on the safety, efficacy, and immunity of the approved vaccines for mothers and infants. In human placental tissues, the COVID-19 virus has been found by different detection methods. The mechanism by which the virus enters the placental tissue is unclear, which may be related to placental inflammation. The long-term prognosis of pregnant women with COVID-19 remains unclear and requires further detailed investigation.

Androgenetic alopecia and COVID-19: A review of the hypothetical role of androgens

The coronavirus disease 2019 (COVID‐19) has become the most emerging health issue globally. A prompt investigation regarding disease management and treatment is crucial for decreasing the burden of the disease. Many explorations and hypotheses have been posed, but the definite treatment has not been determined for COVID‐19. Recent studies described a substantial prevalence of COVID‐19 and also a higher rate of morbidity and mortality in men afflicted with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection. The gender‐related discordance in COVID‐19 infection may be due to hormonal differences, socioeconomic factors, genetic susceptibility, gender‐related comorbidities, and habits like alcohol consumption. On the other hand, several studies proposed that androgens could improve the immune system and have a protective role in COVID‐19, and decreased levels of androgens might be associated with unsatisfactory outcomes. In the field of dermatology, androgenetic alopecia (AGA) is correlated with a hyperandrogenic state and may be related to COVID‐19 severity. Furthermore, recent research has assessed the plausible association of AGA and COVID‐19. In this review, we investigate all evidence on AGA and its relationship with COVID‐19, including the possible role of androgens in COVID‐19 severity and outcomes as well as candidate androgen‐related drugs for the treatment of COVID‐19.

SARS-CoV-2 Viral Entry Proteins in Hyperandrogenemic Female Mice: Implications for Women with PCOS and COVID-19

SARS-CoV-2, the causative agent of COVID-19, infects host cells using the angiotensin I converting enzyme 2 (ACE2) as its receptor after priming by host proteases, including TMPRSS2. COVID-19 affects multiple organ systems, and male patients suffer increased severity and mortality. Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder in reproductive-age women and is characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. PCOS is associated with obesity and cardiometabolic comorbidities, both being risk factors associated with severe COVID-19 pathology. We hypothesize that elevated androgens in PCOS regulate SARS-CoV-2 entry proteins in multiple tissues increasing the risk for this population. Female mice were treated with dihydrotestosterone (DHT) for 90 days. Body composition was measured by EchoMRI. Fasting glucose was determined by an enzymatic method. mRNA and protein levels of ACE2, Tmprss2, Cathepsin L, Furin, Tmprss4, and Adam17 were quantified by RT-qPCR, Western-blot, or ELISA in tissues, serum, and urine. DHT treatment increased body weight, fat and lean mass, and fasting glucose. Ace2 mRNA was upregulated in the lung, cecum, heart, and kidney, while downregulated in the brain by DHT. ACE2 protein was upregulated by DHT in the small intestine, heart, and kidney. The SARS-CoV-2 priming proteases Tmprss2, Cathepsin L, and Furin mRNA were upregulated by DHT in the kidney. ACE2 sheddase Adam17 mRNA was upregulated by DHT in the kidney, which corresponded with increased urinary ACE2 in DHT treated mice. Our results highlight the potential for increased cardiac, renal, and gastrointestinal dysfunction in PCOS women with COVID-19.

Potential risk for developing severe COVID-19 disease among anabolic steroid users

A severe case of COVID-19 was observed in an otherwise healthy 28-year-old man who had taken oxandrolone 40 mg/day as an anabolic steroid. The patient had been taking oxandrolone for enhanced bodybuilding 30 days prior to presenting to an outpatient clinic with COVID-19 symptoms. The patient reported that his symptoms have rapidly worsened over the course of 4 days prior to presenting at the clinic. As part of an experimental antiandrogen treatment for hyperandrogenic men suffering from COVID-19, he was administered a single 600 mg dose of the novel antiandrogen proxalutamide. Twenty-four hours after administration of this dose, marked improvement of symptoms and markers of disease severity were observed. To our knowledge, this is the first case that potentially links anabolic steroid use to COVID-19 disease severity.

Proxalutamide Significantly Accelerates Viral Clearance and Reduces Time to Clinical Remission in Patients with Mild to Moderate COVID-19: Results from a Randomized, Double-Blinded, Placebo-Controlled Trial

Background The entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into type II pneumocytes is dependent on a modification of viral spike proteins by transmembrane protease serine 2 (TMPRSS2) expressed on the surface of human cells. TMPRSS2 is regulated by the androgen receptor, hence, SARS-CoV-2 infectivity is indirectly dependent on androgenic status and phenotype. Previously, we have reported that men affected by androgenetic alopecia (AGA) are overrepresented in severe coronavirus disease 2019 (COVID-19). Additionally, we have reported that men taking antiandrogenic drugs, e.g., 5-alpha-reductase inhibitors (5ARis), are less likely to have severe COVID-19. Here we aimed to test whether the androgen receptor antagonist, Proxalutamide, would be a beneficial treatment for subjects with SARS-CoV-2 infection. Methods Male and female subjects were recruited to a double-blinded, randomized, prospective, investigational study of Proxalutamide for the treatment of COVID-19. Mild to moderate, non-hospitalized subjects, who were confirmed positive for SARS-CoV-2, were treated with either Proxalutamide 200 mg/day or placebo. Endpoints for the study were remission time (days) and the percentage of subjects confirmed negative for SARS-CoV-2 on Day 7 after treatment. A negative SARS-CoV-2 test was defined by concentration-time (Ct)>40 determined by real-time reverse transcription-polymerase chain reaction (rtPCR). Results Two-hundred thirty-six (2360 subjects were included in the study (108 female, 128 male); 171 were randomized to the Proxalutamide arm and 65 were in the placebo group. On Day 7, SARS-CoV-2 became non-detectable with rtPCR (cT>40) in 82% of the subjects in the Proxalutamide group versus 31% in the placebo group (p < 0.001). The average clinical remission time for patients treated with Proxalutamide was 4.2 ±5.4 days versus 21.8 ±13.0 days in the placebo arm (p < 0.001). Conclusion Proxalutamide significantly accelerated viral clearance on Day 7 in mild to moderate COVID-19 patients versus placebo. Further, the time to clinical remission was significantly reduced in patients treated with Proxalutamide versus placebo.

Early Antiandrogen Therapy With Dutasteride Reduces Viral Shedding, Inflammatory Responses, and Time-to-Remission in Males With COVID-19: A Randomized, Double-Blind, Placebo-Controlled Interventional Trial (EAT-DUTA AndroCoV Trial - Biochemical)

Background and objective

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cell entry and subsequent infectivity are mediated by androgens and the androgen receptors through the regulation of transmembrane protease, serine 2 (TMPRSS2). Androgenetic alopecia (AGA) predisposes males to severe coronavirus disease 2019 (COVID-19) disease, while the use of 5-alpha-reductase inhibitors (5ARis) and androgen receptor antagonists reduce COVID-19 disease severity. In this study, we aimed to determine the potential benefit of dutasteride, a commonly used broad and potent 5ARi, as a treatment for COVID-19.

Design, setting, and participants

The study was conducted at outpatient clinics. Subjects presented to the clinics with a positive reverse transcription-polymerase chain reaction (RT-PCR) test taken within 24 hours of recruitment. All subjects presented with mild to moderate symptoms.

Interventions

Subjects were given either dutasteride 0.5 mg/day or placebo for 30 days or until full COVID-19 remission. All subjects received standard therapy with nitazoxanide 500 mg twice a day for six days and azithromycin 500 mg/day for five days.

Main outcome(s) and measure(s)

The main outcome(s) and measure(s) were as follows: time to remission, oxygen saturation (%), positivity rates of RT-PCR-SARS-CoV-2, and biochemical analysis [ultrasensitive C-reactive protein (usCRP), D-dimer, lactate, lactate dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), ultrasensitive troponin, and ferritin].

Results

Subjects taking dutasteride (n=43) demonstrated reduced fatigue, anosmia, and overall disease duration compared to subjects taking a placebo (n=44) (p<.0001 for all). Compared to the placebo group, on Day seven, subjects taking dutasteride had a higher virologic remission rate (64.3% versus 11.8%; p=.0094), higher clinical recovery rate (84.7% versus 57.5%; p=.03), higher mean [standard deviation: SD] oxygen saturation (97.0% [1.4%] versus 95.7% [2.0%]; p=.02), lower median [Interquartile range: IQR] usCRP (0.34 mg/L [0.23 mg/L-0.66 mg/L] versus 1.47 mg/L [0.70 mg/L-3.37 mg/L]; p<.0001), lower median [IQR] lactate (2.01 mmol/L [1.12 mmol/L-2.43 mmol/L] versus 2.66 mmol/L [2.05 mmol/L-3.55 mmol/L]; p=.0049), lower median [IQR] ESR (5.0 mm/1h [3.0 mm/1h-11.0 mm/1h] versus 14.0 mm/1h [7.25 mm/1h-18.5 mm/1h]; p=.0007), lower median [IQR] LDH (165 U/L [144 U/L-198 U/L] versus 210 U/L [179 U/L-249 U/L]; p=.0013) and lower median [IQR] troponin levels (0.005 ng/mL [0.003 ng/mL-0.009 ng/mL] versus 0.007 ng/mL [0.006 ng/mL-0.010 ng/mL]; p=.048).

Conclusions and relevance

The findings from this study suggest that in males with mild COVID-19 symptoms undergoing early therapy with nitazoxanide and azithromycin, treatment with dutasteride reduces viral shedding and inflammatory markers compared to males treated with a placebo.

The AndroCoV Clinical Scoring for COVID-19 Diagnosis: A Prompt, Feasible, Costless, and Highly Sensitive Diagnostic Tool for COVID-19 Based on a 1757-Patient Cohort

Introduction A major barrier for successful therapeutic approaches for COVID-19 is the inability to diagnose COVID-19 during the viral replication stage, when drugs with potential antiviral activity could demonstrate efficacy and preclude progression to more severe stages. Reasons that hamper an earlier diagnosis of COVID-19 include the unspecific and mild symptoms during the first stage, the delay in the diagnosis and specific management caused by the requirement of a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV-2 for the diagnosis of COVID-19, and the insufficient sensitivity of the RT-PCR-SARS-CoV-2, converse to what is recommended for a screening test during an outbreak. More sensitive and earlier diagnostic tools for COVID-19 should be unraveled as a key strategy for a breakthrough change in the disease course and response to specific therapies, particularly those that target the blockage of viral shedding. We aimed to create an accurate, sensitive, easy-to-perform, and intuitive clinical scoring for the diagnosis of COVID-19 without the need for an RT-PCR-SARS-CoV-2 (termed The AndroCoV Clinical Scoring for COVID-19 Diagnosis), resulting from a 1,757 population cohort, to eventually encourage the management of patients with a high pre-clinical likelihood of presenting COVID-19, independent of an RT-PCR-SARS-COV-2 test, to avoid delays and loss of appropriate timing for potential therapies. Methods This is a post-hoc analysis of clinical data prospectively collected of the Pre-AndroCoV and AndroCov Trials, which resulted in scorings for the clinical diagnosis of COVID-19 based on the likelihood of presenting with actual COVID-19 according to the number of symptoms, presence of anosmia, and known positive household contact. Sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and accuracy were calculated for subjects screened in two different periods and both periods together, for females, males, and both, in a total of nine different scenarios, according to combinations of one, two, or three or more symptoms or the presence of anosmia in subjects without known positive household contacts, and no symptoms, one, two, or three or more symptoms, or presence of anosmia or ageusia in subjects with known positive household contacts. Scorings that yielded the highest pre-test probability, sensitivity, and accuracy were selected. Results Of the 1,757 patients screened, 1,284 were diagnosed with COVID-19. The scoring that required: (1) two or more symptoms, or anosmia or ageusia alone, for subjects without known contact; or (2) one or more symptoms, including anosmia or ageusia alone, when with known positive contacts presented the highest accuracy (80.4%) among all combinations attempted, and higher sensitivity (85.7%) than RT-PCR-SARS-CoV-2 commercially available kit tests. Conclusion The AndroCoV clinical scoring for COVID-19 diagnosis was demonstrated to be a feasible, easy, costless, and sensitive diagnostic tool for the clinical diagnosis of COVID-19. Because the clinical diagnosis of COVID-19 avoids delays in specific treatments, particularly for high-risk populations, prevents false-negative diagnosis, and reduces diagnostic costs, this diagnostic tool should be considered as an option for COVID-19 diagnosis, at least while SARS-CoV-2 is the prevailing circulating virus and vaccination rate is below the required for herd immunity.
