    • 摘要: Hirsutism is an endocrine disorder where women develop excess growth of terminal hairs in a male pattern. This study evaluated the concentrations of cholesterol, glucose and testosterone in bearded women in the Amassoma metropolis of Bayelsa state. In a view to determining whether hirsutism has an effect/relationship with the biochemical parameters estimated, a total of 50 bearded and 50 non-bearded women were recruited for this study. Based on a cross-sectional study, group A and B were appropriately matched for age and BMI. The concentrations of the biochemical parameters were measured using WHO-approved method. Bearded females had significantly higher (p ≤ 0.05) cholesterol concentration (4.41 ± 1.09 mmol/L) when compared with the non-bearded (control) women. Furthermore, the mean concentrations of testosterone and glucose were higher in the bearded female group when compared with the non-bearded. The study established that women with hirsutism have associated hypertestosteronemia, hypercholesterolemia and hyperglycemia.

    • 摘要: Background: The condition known as polyneuropathy causes peripheral nerve disability, and is characterized by symmetrical distal numbness and paresthesia, often accompanied by pain and weakness. With the advancement of the pandemic in Brazil and in the world, the need for therapies as well as prophylaxis became the main focus in disease control as the viral vector platform vaccine AstraZeneca. Some effects were observed over the period of application. Case Summary: A male patient, 63 years old, previously vaccinated for COVID-19, developed active infection by the virus and in his convalescent period presented intense weakness, with prejudice to his daily activities, including personal hygiene ones. Conclusion: The patient made a complete recovery after combination therapy with testosterone derivates, ivermectin, corticosteroids, and vitamins, besides rehabilitation.

    • 摘要: Background: The presence of the angiotensin-converting enzyme 2 (ACE2) receptor, the main entry receptor for SARS-CoV-2 in lung alveolar tissue, in Sertoli and Leydig cells of the adult testis, may suggest possible testicular involvement during SARS-CoV-2 infection. Our aim was to investigate the impact of COVID-19 on gonadal function in men. Methods: This was a cross-sectional descriptive and analytical study in a population of men aged below 65 years of age with SARS-CoV-2. Not included in the study were any subjects on testosterone replacement therapy or with a known condition that could create hypogonadism. We recruited patients through a questionnaire and then performed total testosterone and SHBG analysis at 8 hours and 2 months post infection by ELISA. We used the Spearman Rho test for statistical analysis of correlations. The significance level was set at 0.05. Results: The sample consisted of 40 male COVID positive patients with a mean age of 46.4 ± 11.8 years. Eight patients were reviewed after infection. The mean total testosterone was 11 ng/ml ± 2.4 and the SHBG was 113 nmol/l ± 66.9 during infection. In the 8 patients reviewed after infection, median total testosterone decreased during infection (11 ng/ml) and increased after infection (12.7 ng/ml), this result was statistically significant (P = 0.028). Median SHBG during infection was increased (115.7 nmol/l) and after infection was decreased (82 nmol/l). There was a statistically significant (P = 0.04) and positive correlation between serum testosterone and SHBG levels in patients with severe infection. Conclusion: There could be a transient relative hypogonadism during SARS-CoV-2 infection, more marked in the severe forms of the disease with a tendency to improve after infection.

    • 摘要: BACKGROUND Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)can produce a wide range of clinical manifestations from asymptomatic to life-threatening.Various researchers have worked to elucidate the pathogenic mechanisms underlying these variable presentations.Differences in individual responses to systemic inflammation and coagulopathy appear to be modulated by several factors,including sex steroid hormones.Transgender men or non-binary individuals who undergo gender-affirming hormone therapy(GAHT)are a unique population of interest for exploring the androgen-mediated coronavirus disease 2019(COVID-19)hypothesis.As the search for reliable and effective COVID-19 treatments continues,understanding the risks and benefits of GAHT may mitigate COVID-19 related morbidity and mortality in this patient population.AIM To investigate the potential role of GAHT in the development of COVID-19 infections and complications.METHODS This systematic review implemented an algorithmic approach using PRISMA guidelines.PubMed,Scopus,Google Scholar top 100 results,and archives of Plastic and Reconstructive Surgery was on January 12,2022 using the key words“gender”AND“hormone”AND“therapy”AND“COVID-19”as well as associated terms.Non-English articles,articles published prior to 2019(prior to COVID-19),and manuscripts in the form of reviews,commentaries,or letters were excluded.References of the selected publications were screened as well.RESULTS The database search resulted in the final inclusion of 14 studies related to GAHT COVID-19.Of the included studies,only two studies directly involved and reported on COVID-19 in transgender patients.Several clinical trials looked at the relationship between testosterone,estrogen,and progesterone in COVID-19 infected cis-gender men and women.It has been proposed that androgens may facilitate initial COVID-19 infection,however,once this occurs,testosterone may have a protective effect.Multiple clinical studies have shown that low baseline testosterone levels in men with COVID-19 are associated with worsening outcomes.The role of female sex hormones,including estrogen and progesterone have also been proposed as potential protective factors in COVID-19 infection.This was exemplified in multiple studies investigating different outcomes in pre-and post-menopausal women as well as those taking hormone replacement therapy.Two studies related specifically to transgender patients and GAHT found that estrogen and progesterone could help protect men against COVID-19,and that testosterone hormone therapy may increase the risk of contracting COVID-19.CONCLUSION Few studies were found related to the role of GAHT in COVID-19 infections.Additional research is necessary to enhance our understanding of this relationship and provide better care for transgender patients.
