LOng COvid COmorbidities: Evaluation of Andrological, Reproductive and Sexual Functions in Patients Recovered From COVID-19

Обзор

Considering the compelling amount of studies focused on patients in the active phase of COVID-19 disease and the scarcity of studies focused on patient cured from disease aimed at evaluating the sequelae of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, the purpose of the study is to investigate, in patients recovered from COVID-19 disease: 1) whether SARS-CoV-2 infection has induced in male patients, a primary (testicular) and / or secondary (pituitary) damage to the hypothalamic-pituitary-testicular hormonal axis, structural and / or functional damage to the testis and penis, sexual dysfunction or fertility disorders; 2) the prevalence in male and female patients of chemosensory symptoms (olfactory dysfunction) and assess whether there is a correlation between the prevalence, severity, duration and eventual persistence of olfactory dysfunction and the severity of COVID-19 disease. Patients will be evaluated at baseline (at discharge from infectious and/or pneumology unit) and after 3- 12 months. A better definition of the prevalence and type of sequelae after recovery from COVID-19 disease could significantly improve the therapeutic management and long-term follow-up of these patients, with a relevant impact in terms of health resources and public health.

Подробное описание

The testis is among the male organs with the highest expression of angiotensin-converting enzyme 2 (ACE2), particularly in Sertoli cells, Leydig cells, spermatogonia, spermatocytes and spermatids; therefore, the possibility of SARS-CoV-2 infection spread to the testis and of a direct damage to testicular endocrine function and spermatogenesis is not a negligible aspect. In addition, the possibility of indirect testicular damage has been suggested; indeed, orchitis has been reported in patients with SARS-CoV-2, favored by the activation of a systemic inflammatory response to SARS-CoV-2 infection, and changes in gonadotropin levels that support the presence of subclinical or compensated hypogonadism associated with SARS-CoV-2 infection have been highlighted, although the possibility of effects mediated by the inflammatory state, the use of corticosteroids or stress cannot be excluded. Controversial data are available regarding the possibility that SARS-CoV-2 infection can actually spread to semen, and there is currently no evidence of a direct association between SARS-CoV-2 infection and male infertility, although an altered expression of ACE2 has been associated with non-obstructive azoospermia. The widespread expression of ACE2 by endothelial cells represents an additional susceptibility alert in relation to the male reproductive system, as well as to sexual function, in particular for the potential direct and indirect effects of SARS-CoV-2 infection on the penile vascular endothelium; indeed, multiple evidences support the presence of a multi-organ endothelial dysfunction in SARS-CoV-2 infection, connected to the direct tropism of the virus mediated by the diffuse expression of ACE-2 in endothelial cells, as well as to the systemic inflammation through the increased production of pro-inflammatory cytokines which mediate/favor the alteration of the function and permeability of the vascular endothelium. In this context, erectile dysfunction could represent a long-term complication of Covid-19; penile vascular endothelial dysfunction is indeed recognized as the dominant mechanism in the onset of vasculogenic erectile dysfunction, and preliminary studies highlight a significantly higher prevalence of erectile dysfunction in patients with Covid-19, regardless of other variables affecting erectile function, such as psychological state, age and body mass index. Anosmia/hyposmia, associated or not with ageusia, has been frequently reported as a symptom of the onset of SARS-CoV-2 infection, but it could also remain the only clinical manifestation in some paucisymptomatic patients. The incidence of anosmia in SARS-CoV-2 patients is around values between 33.9% and 68%, with a predominance in the female sex. The etiopathogenetic mechanisms underlying the onset of anosmia in these patients are yet to be fully clarified; the main mechanisms proposed include damage to olfactory sensory neurons or direct invasion of the brain via the olfactory bulb. Smell disorders affect nutrition and quality of life with important psycho-social consequences. In this scenario, it appears of primary importance to evaluate and monitor the long-term evolution of anosmia in post SARS-CoV-2 infection through an objective assessment.

The aim of the study is to investigate whether in male patients recovered from COVID-19 disease, SARS-CoV-2 infection has induced: 1) alterations of seminal parameters (oligo-, astheno-, teratozoospermia, azoospermia, necrozoospermia, leukocytospermia, hypo / hyperposia); 2) hypogonadism; 3) morpho-structural alterations of the testis evaluated by ultrasonography (testicular hypotrophy, testicular and / or epididymal inhomogeneity, testicular calcifications / microlithiasis, testicular solid lesions, hydrocele, varicocele, altered testicular and / or epididymal vascularization); 4) prostate-vesicular morpho-structural alterations assessed by ultrasonography; 5) morpho-structural and hemodynamic alterations of the penis evaluated by ultrasonography with Color and PowerDoppler performed at baseline, and in some selected cases which will be identified as pathological at baseline, also performed dynamically after intra-cavernous infiltration of prostaglandin-E1 (PGE1) (morphological alterations, nodules, alterations of the albuginea tunic, presence of fibrotic or calcified plaques, morphological and haemodynamic alterations of the cavernous arteries, anastomosis between the cavernous arteries and the dorsal artery, presence of other collateral circulation, presence and site of any occlusions); 6)male sexual dysfunctions (erectile dysfunction, premature ejaculation, hypoactive sexual desire disorder) assessed by sexological questionnaires. Moreover, the aim of the study is also to investigate whether in male and female patients recovered from COVID-19 disease, SARS-CoV-2 infection has induced an olfactory dysfunction, with evaluation of the eventual correlation between prevalence, severity, duration and possible permanence of olfactory dysfunction and the severity of the COVID-19 disease, using the Sniffin 'Sticks test for the evaluation of: odor threshold (T), odor discrimination (D) and odor identification (I) (TDI score).

Patients will be evaluated at baseline (at discharge from infectious and/or pneumology unit) and after 3- 12 months.
