LOng COvid COmorbidities: Endocrine,Metabolic,Neuropsychiatric,Muscle,Cardiovascular,Pulmonary,Dermatologic Dysfunctions

Assessment of:thyroid-stimulating hormone(TSH),free triiodothyronine (FT3), free thyroxine (FT4),calcitonin,antibodies against thyroglobulin (AbTG) and against thyroperoxidase (AbTPO),adrenocorticotropic hormone (ACTH),cortisol, luteinizing hormone (LH),follicle-stimulating hormone(FSH),Testosterone,17-beta estradiol,sex hormone binding globulin (SHBG),progesterone, prolactin (PRL), growth hormone (GH), insulin growth factor-1 (IGF-1), dehydroepiandrosterone sulphate (DHEAS),delta 4-androstenedione,aldosterone,renin,glycemia, insulinemia, total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, HbA1c, vitamin D, adiponectin, irisin, IL-6.Thyroid and ovarian ultrasounds, pituitary and adrenal MRI will be performed as well. Body composition will be assessed with bioimpedance analysis and DXA scans.Female sexual dysfunctions will be evaluated with Female Sexual Function Index (FSFI), Sexual Inhibition and Sexual Excitation Scale (SIS/SES),Body Uneasiness Test (BUT).

Questions will be collected regarding the tolerance to physical activity and modifications after diagnosis of Covid. Muscular strength will be assessed by means of tests (Medical Research Council Scale) and dynamometers. Balance will be assessed with a Romberg test, tolerance to stress will be assessed by means of cyclometer.

Validated questionnaires will be collected to investigate depression (Beck Depression Inventory-II, BDI-II), apathy (Apathy Evaluation Scale, AES), anxiety (Test Anxiety Inventory, TAI), attention and cognitive functions (Montreal Cognitive Assessment and Quick Mild Cognitive Impairment). Fatigue will be assessed by Fatigue Rating Scale (FRS) and Fatigue Severity Scale (FSS). Muscle power will be assessed by six-minute walking test and sit and stand up test. The presence of myopathy will be evaluated by mean electrophysiological study.

Muscle biopsy will be performed upon need.

Modified Medical Research council questionnaire will be administered for evaluating of the dyspnoea level. Complete respiratory status assessment, including global spirometry, CO lung diffusion capacity and arterial gases analysis will be run. HRCT - high resolution CT scan of the chest - will be performed in selected cases to rule out the eventual sequelae of SARS-Cov2 related pneumonia.

Cardiological assessment will be run upon data collected from: Short Form-36 Health Survey (SF36), echocardiogram at rest and during stress tests, six-minute walking test, N-terminal fragment brain natriuretic peptides (NT-proBNP)

The assessment of the potential post-thrombotic vascular damage will comprise the investigation of prevalence of previously unknown deep venous thrombosis by ultrasonography.

Dermatology evaluation will account on: thrichoscopy, dermoscopy, onychoscopy and capillaroscopy, confocal microscopy, skin ultrasonography

Tissue biopsy will be performed upon need.
