ABSTRACT

Objective: Coronavirus disease-2019 (COVID-19) causes acute respiratory distress syndrome. Patients with adrenal insufficiency (AI) may develop severe complications due to this infection and should undergo COVID-19 vaccination; however, there is no consensus about the management of their replacement therapy. The aim of our study was to evaluate the tolerability and need for glucocorticoid dose adjustment related to COVID-19 mRNA vaccines in a cohort of patients with AI. Design and methods: We prospectively administered to 88 patients (51 M/37 F; mean age: 62.3 ± 16 years), with AI (28 primary and 60 secondary AI), a questionnaire about the occurrence, severity and duration of the side effects and the need for glucocorticoid dose adjustment within 1 week after the first and the second dose of COVID-19 mRNA vaccines (Pfizer-BioNTech and Moderna). Results: Side effects of mild to moderate severity occurred in about 70% of patients after both vaccine doses. The most common adverse events were pain at the injection site, fatigue, fever and flu-like symptoms. The occurrence and severity of the side effects were not correlated to gender, type of AI and mRNA vaccine, but their total number was higher after the second vaccine dose. Doubling the oral glucocorticoid dose was needed in up to 8% of patients, especially after the second vaccine dose, but no parenteral administration was required. Conclusions: COVID-19 mRNA vaccines were well tolerated in patients with AI. Side effects were similar to those observed in the general population, and increasing glucocorticoid replacement therapy before vaccine administration was not needed.

ABSTRACT

Background Systemic inflammation and male hypogonadism are 2 increasingly recognized "nonconventional" risk factors for long-QT syndrome and torsades de pointes (TdP). Specifically, inflammatory cytokines prolong, while testosterone shortens the heart rate-corrected QT interval (QTc) via direct electrophysiological effects on cardiomyocytes. Moreover, several studies demonstrated important interplays between inflammation and reduced gonad function in men. We hypothesized that, during inflammatory activation in men, testosterone levels decrease and that this enhances TdP risk by contributing to the overall prolonging effect of inflammation on QTc. Methods and Results We investigated (1) the levels of sex hormones and their relationship with inflammatory markers and QTc in male patients with different types of inflammatory diseases, during active phase and recovery; and (2) the association between inflammatory markers and sex hormones in a cohort of male patients who developed extreme QTc prolongation and TdP, consecutively collected over 10 years. In men with active inflammatory diseases, testosterone levels were significantly reduced, but promptly normalized in association with the decrease in C-reactive protein and interleukin-6 levels. Reduction of testosterone levels, which also inversely correlated with 17-ß estradiol over time, significantly contributed to inflammation-induced QTc prolongation. In men with TdP, both active systemic inflammation and hypogonadism were frequently present, with significant correlations between C-reactive protein, testosterone, and 17-ß estradiol levels; in these patients, increased C-reactive protein and reduced testosterone were associated with a worse short-term outcome of the arrhythmia. Conclusions During systemic inflammatory activation, interleukin-6 elevation is associated with reduced testosterone levels in males, possibly deriving from an enhanced androgen-to-estrogen conversion. While transient, inflammatory hypotestosteronemia is significantly associated with an increased long-QT syndrome/TdP risk in men.

ABSTRACT

BACKGROUND: While SARS-CoV-2 similarly infects men and women, COVID-19 outcome is less favorable in men. Variability in COVID-19 severity may be explained by differences in the host genome. METHODS: We compared poly-amino acids variability from WES data in severely affected COVID-19 patients versus SARS-CoV-2 PCR-positive oligo-asymptomatic subjects. FINDINGS: Shorter polyQ alleles (≤22) in the androgen receptor (AR) conferred protection against severe outcome in COVID-19 in the first tested cohort (both males and females) of 638 Italian subjects. The association between long polyQ alleles (≥23) and severe clinical outcome (p = 0.024) was also validated in an independent cohort of Spanish men <60 years of age (p = 0.014). Testosterone was higher in subjects with AR long-polyQ, possibly indicating receptor resistance (p = 0.042 Mann-Whitney U test). Inappropriately low serum testosterone level among carriers of the long-polyQ alleles (p = 0.0004 Mann-Whitney U test) predicted the need for intensive care in COVID-19 infected men. In agreement with the known anti-inflammatory action of testosterone, patients with long-polyQ and age ≥60 years had increased levels of CRP (p = 0.018, not accounting for multiple testing). INTERPRETATION: We identify the first genetic polymorphism that appears to predispose some men to develop more severe disease. Failure of the endocrine feedback to overcome AR signaling defects by increasing testosterone levels during the infection leads to the polyQ tract becoming dominant to serum testosterone levels for the clinical outcome. These results may contribute to designing reliable clinical and public health measures and provide a rationale to test testosterone as adjuvant therapy in men with COVID-19 expressing long AR polyQ repeats.
