ABSTRACT
BACKGROUND: Hypertension management in older patients represents a challenge, particularly when hospitalized. OBJECTIVE: The objective of this study is to investigate the determinants and related outcomes of antihypertensive drug prescription in a cohort of older hospitalized patients. METHODS: A total of 5671 patients from REPOSI (a prospective multicentre observational register of older Italian in-patients from internal medicine or geriatric wards) were considered; 4377 (77.2%) were hypertensive. Minimum treatment (MT) for hypertension was defined according to the 2018 ESC guidelines [an angiotensin-converting-enzyme-inhibitor (ACE-I) or an angiotensin-receptor-blocker (ARB) with a calcium-channel-blocker (CCB) and/or a thiazide diuretic; if >80 years old, an ACE-I or ARB or CCB or thiazide diuretic]. Determinants of MT discontinuation at discharge were assessed. Study outcomes were any cause rehospitalization/all cause death, all-cause death, cardiovascular (CV) hospitalization/death, CV death, non-CV death, evaluated according to the presence of MT at discharge. RESULTS: Hypertensive patients were older than normotensives, with a more impaired functional status, higher burden of comorbidity and polypharmacy. A total of 2233 patients were on MT at admission, 1766 were on MT at discharge. Discontinuation of MT was associated with the presence of comorbidities (lower odds for diabetes, higher odds for chronic kidney disease and dementia). An adjusted multivariable logistic regression analysis showed that MT for hypertension at discharge was associated with lower risk of all-cause death, all-cause death/hospitalization, CV death, CV death/hospitalization and non-CV death. CONCLUSIONS: Guidelines-suggested MT for hypertension at discharge is associated with a lower risk of adverse clinical outcomes. Nevertheless, changes in antihypertensive treatment still occur in a significant proportion of older hospitalized patients.

BACKGROUND: Ocular manifestations of granulomatosis with polyangiitis (GPA) have been reported in a limited number of studies and with largely variable frequency. Here we report on the clinical, diagnostic, and therapeutic features of a cohort of 63 GPA patients, with particular regard to 22 of them with ophthalmic involvement (35%). METHODS: Clinical manifestations, results of immunological findings, histopathological pictures, imaging data, Birmingham Vasculitis Activity Score, therapeutic regimens, and outcomes were retrospectively analyzed. At diagnosis, in addition to a structured clinical assessment, all patients underwent a comprehensive ophthalmologic examination. RESULTS: The most frequently involved organs were kidneys, lungs, ear/nose/throat, and eyes. Ocular manifestations were bilateral in 32%. The three most commonly diagnosed ophthalmologic manifestations were scleritis (36%), retro-orbital pseudotumor or orbital mass (23%), and episcleritis (13%). Ocular and systemic involvement were simultaneously present at onset in 41% of the patients; systemic involvement was followed by ocular lesions in 36%; ocular inflammation was followed by systemic manifestations in 18%; and an orbital mass in the absence of systemic disease characterized 5%. Glucocorticoids plus cyclophosphamide and glucocorticoids plus rituximab were the combined therapies most frequently employed during remission induction and remission maintenance, respectively. Persistent ophthalmologic and extra-ocular remissions were achieved in 77 and 64% of the patients, respectively. One to three systemic relapses were diagnosed in 7 patients (31.8%). At the last follow-up, a visual outcome 20/40 or better in 31 (70%) of 44 eyes was determined. CONCLUSIONS: The eye was involved in over one third of our patients with GPA. Increased awareness, early diagnosis, and multi-specialty collaboration are critical in achieving a favorable outcome of GPA.

BACKGROUND: Angiotensin Converting Enzyme 2 (ACE2) is an endothelial cell receptor used by SARS-CoV- 2 virus to enter cells. Pulmonary function tests (PFTs), mainly spirometry, are the main diagnostic tools for most respiratory diseases. PFTs are mandatory for assessing the response to therapy. AIM: We evaluated patients after the SARS-CoV-2 infection through flow-volume spirometry that evaluates the role of drugs inhibiting the ACE2 pathway. MATERIAL AND METHODS: We evaluated 112 Caucasian patients 3-6 months after COVID-19 disease, i.e. after the date of negative molecular or antigenic nasopharyngeal swab. The series of patients showed a great variability due to a wide spectrum of age, the severity of disease manifestations, hospitalization, invasive/non-invasive ventilation, comorbidities, the presence/absence of a previous pneumological diagnosis and the variants of the virus. Patients were divided into those who were being treated with angiotensin receptor blocker (ARB) or ACE2 inhibitors (ACEi) (ARB/ACEi, group 1, 23 females and 12 males, aged 63.63 ± 10.40), and those who were not treated with these drugs (group 2, 38 females and 37 males, aged 55.12 ± 16.51). Distal airflow obstruction (DAO) was evaluate as forced expiratory flow (FEF) at 25%, 50% and 75% of total flow. RESULTS: Group 1 presented lower peripheral oxygen saturation percentage vs group 2 (96.54 ± 3.06 vs 97.30 ± 1.19%, p < 0.05). Spirometry data were worst in group1: Forced expiratory volume at first minute (FEV1) (91.20 ± 17.09 vs 97.56 ± 16.40%, p < 0.05), Forced vital capacity (94.06 ± 17.48 vs 99.13 ± 17.71%, p < 0.05), and Tiffenau Index (0.78 ± 0.12 vs 0.84 ± 0.10, p < 0.05). There was a DAO in group1. In group 1, we found also a reduction in FEF 25 (73.97 ± 27.28 vs 86.89 ± 22.44%, p < 0.05), FEF 50 (74.69 ± 33.01 vs 85.67 ± 23.74%, p < 0.05), and FEF 25-75 (74.14 ± 35.03 vs 83.92 ± 25.38%, p < 0.05) but not in FEF 75 (73.06 ± 39.37 vs 82.27 ± 43.33%, p < 0.05). DISCUSSION: In patients treated with ARB/ACEi the indexes of respiratory function were shifted towards the lower limits (albeit within normal limits). These parameters were significantly reduced compared to patients not treated with these drugs. This indicates that the COVID-19 disease is not only a pulmonary disease, but also a vascular one.

The pathophysiology of atrial fibrillation (AF) may involve atrial fibrosis/remodeling and dysfunctional endothelial activities. Despite the currently available treatment approaches, the progression of AF, its recurrence rate, and the high mortality risk of related complications underlay the need for more advanced prognostic and therapeutic strategies. There is increasing attention on the molecular mechanisms controlling AF onset and progression points to the complex cell to cell interplay that triggers fibroblasts, immune cells and myofibroblasts, enhancing atrial fibrosis. In this scenario, endothelial cell dysfunction (ED) might play an unexpected but significant role. microRNAs (miRNAs) regulate gene expression at the post-transcriptional level. In the cardiovascular compartment, both free circulating and exosomal miRNAs entail the control of plaque formation, lipid metabolism, inflammation and angiogenesis, cardiomyocyte growth and contractility, and even the maintenance of cardiac rhythm. Abnormal miRNAs levels may indicate the activation state of circulating cells, and thus represent a specific read-out of cardiac tissue changes. Although several unresolved questions still limit their clinical use, the ease of accessibility in biofluids and their prognostic and diagnostic properties make them novel and attractive biomarker candidates in AF. This article summarizes the most recent features of AF associated with miRNAs and relates them to potentially underlying mechanisms.

Background and Objectives: COVID-19 induces massive systemic inflammation. Researchers have spent much time and effort finding an excellent and rapid image tool to evaluate COVID-19 patients. Since the pandemic's beginning, lung ultrasound (LUS) has been identified for this purpose. Monoclonal antibodies (mAb) were used to treat mild patients and prevent respiratory disease worsening. Materials and Methods: We evaluated 15 Caucasian patients with mild COVID-19 who did not require home oxygen, treated with Bamlanivimab and Etesevimab (Group 1). A molecular nose-throat swab test confirmed the diagnosis. All were office patients, and nobody was affected by respiratory failure. They were admitted to receive the single-day infusion of mAb treatment in agreement with the Italian Drug Agency (AIFA) rules for approval. LUS was performed before the drug administration (T0) and after three months (T1). We compared LUS at T1 in other outpatients who came for follow-up and were overlapping at the time of diagnosis for admittance criteria to receive mAb (Group 2). Results: Our COVID-19 outpatients reported no hospitalization in a follow-up visit after recovery. All patients became SARS-CoV-2 negative within one month since T0. LUS score at T0 was 8.23 ± 6.46. At T1 we found a significant decrease in Group 1 LUS score (5.18 ± 4.74; p < 0.05). We also found a significant decrease in the LUS score of Group 1 T1 compared to Group2 T1 (5.18 ± 4.74 vs 7.82 ± 5.21; p < 0.05). Conclusion: Early treatment of the SARS-CoV-2 virus effectively achieves a better recovery from disease and reduces lung involvement after three months as evaluated with LUS. Despite extrapolation to the general population may be done with caution, based on our data this ultrasound method is also effective for evaluating and following lung involvement in COVID-19 patients.

BACKGROUND AND AIM: Left heart remodeling is a well-known pathophysiological effect of arterial hypertension. Right Heart status is not considered in its evaluation. No data are available on right atrium (RA) and its impact on the outcome in hypertension. We wondering to understand whether RA may play a role as a marker of an increased risk for organ damage in well-controlled hypertensives, to probe the clinical significance and whether it could indicate an increased risk. METHODS AND RESULTS: We studied well-controlled hypertensive patients. Heart damage was assessed by echocardiography. Patients were subdivided into those with RA area ≤18 cm2 (normal RA - Group 1) (554 pts, 227 M, aged 60.35 ± 10.48 years) and those >18 cm2 (Increased RA - Group 2) (101 pts, 71 M, age 61.65 ± 9.46 years). Group 2 had a higher left ventricle mass (LVM) and left atrium volume (LAV) both as absolute value (both p < 0.0001) and indexed for body surface area (LVMi p < 0.013; LAVi p = 0.0013). Group 2 showed an increased vascular stiffness (p < 0.0001) and carotid stenosis percentage (p = 0.011). TAPSE (p < 0.0001) resulted significantly increased. In The RA area was significantly correlated directly to LVM and LAV in both groups, but these correlations persisted in indexed values only in Group 2. Moreover, in this group there was a significant direct correlation between RA area and Tricuspid s'wave at echocardiography TDI analysis. Finally, Group 2 had an increased mortality rate compared to Group 1 (Log-Rank p = 0.0006). CONCLUSION: Group 2 hypertensive patients showed more alterations in dimensional and volumetric left heart parameters, and an increased mortality.

BACKGROUND: COVID-19 induces robust systemic inflammation. One of the main complications is the increased coagulation due to endotheliitis. There is an increased incidence of pulmonary embolism (PE) in COVID-19 patients. However, clinical characteristics for a strict analysis are yet to be determined. AIM: We evaluated oxygenation and characteristics in patients with COVID-19 PE (CPE). MATERIAL AND METHODS: We evaluated 215 COVID-19 patients from 1 January to 30 April 2021. We found 18 patients affected by PE (CPE, 50.0% males, aged 67.00 ± 10.86 years). As controls, we used data from patients affected by PE evaluated in our ward between 1 January 2015 and 31 December 2019 (64 patients, 53.1% males, aged 70.88 ± 16.44 years). All patients underwent a complete physical examination, pulmonary computerised tomography, laboratory tests, D-dimers and blood gas analysis at the time of diagnosis. RESULTS: There were no differences in laboratory tests nor in D-dimers between the two groups. In the CPE group we found a significantly increased pO2 (92.83 ± 42.52 vs. 76.11 ± 32.58 mmHg; p < 0.05), difference of oxygen between alveoli and arteries (A-aDO2; 169.3 ± 171.9 vs. 52.97 ± 39.65 mmHg; p < 0.05), and oxygen saturation % (97.06 ± 2.59 vs. 93.77 ± 5.53%; p < 0.05) compared to controls. No difference was found in pCO2 and the ratio between pO2 and percentage of inspired oxygen (P/F). Finally, a significantly decreased urate (3.67 ± 1.49 vs. 5.60 ± 2.10; p < 0.05) was found in CPE compared to controls. In CPE, platelets count presents an inverse correlation to P/F (r = -0.389, p = 0.02) but a direct correlation to A-aDO2 (r = 0.699, p = 0.001). No similar findings were present in controls. DISCUSSION: COVID-19 PE appears to have a different clinical setting. Reduced oxygenation described in PE may not to be considered as a sign of disease. The increased A-aDO2 may indicate that COVID-19 PE involved smaller vessels compared to classical PE. A possible diffuse capillary thrombosis could explain these results.

BACKGROUND: COVID-19 induces robust systemic inflammation. Patients with cardiovascular disease (CVD) are at an increased risk of death. However, much effort is being spent to identify possible predictors of negative outcomes in order to have a more specific clinical setting. CVD scores are a useful tool in evaluating risk of cardiovascular events. AIM: We evaluated oxygenation and characteristics in COVID-19 patients according to cardiovascular risk stratification performed using the Framingham risk score (FRS) for cardiovascular disease. MATERIALS AND METHODS: We evaluated 155 COVID-19 patients (110 males and 45 females, aged 67.43 ± 14.72 years). All patients underwent a complete physical examination, chest imaging, laboratory tests and blood gas analysis at the time of diagnosis. Seventeen patients died (10 males and 7 females, aged 74.71 ± 7.23 years) while the remaining 138 patients (100 males and 38 females, aged 66.07 ± 15.16 years) were alive at discharge. RESULTS: Deceased patients have an increased FRS compared to those that survived (27.37 ± 5.03 vs. 21.33 ± 9.49, p < 0.05). Compared to survivors, the deceased group presents with a significant increase in white blood cells (p < 0.05) and D-dimers (p < 0.05). There was no difference in pCO2, SO2, and in alveolar arteriolar oxygen difference (A-aDO2). On the contrary, in deceased patients there was an increased pO2 (p < 0.05) and a decreased ratio between oxygen inspired and pO2 (P/F; p < 0.05). FRS shows a negative correlation to P/F (r = 0.42, p < 0.05) in the deceased while no correlation was found in the survivors. No other correlation has been found with blood gas parameters or in the inflammation parameters evaluated in the two groups. DISCUSSION: CVD may be considered as a major risk factor for death in COVID-19 patients. The increased risk relates to a reduced lung capacity but it is not related to blood gas values. Similarly, CV risk score results are independent from the inflammatory status of the patients.

COVID-19 is a pandemic disease caused by the new coronavirus SARS-CoV-2 that mostly affects the respiratory system. The consequent inflammation is not able to clear viruses. The persistent excessive inflammatory response can build up a clinical picture that is very difficult to manage and potentially fatal. Modulating the immune response plays a key role in fighting the disease. One of the main defence systems is the activation of neutrophils that release neutrophil extracellular traps (NETs) under the stimulus of autophagy. Various molecules can induce NETosis and autophagy; some potent activators are damage-associated molecular patterns (DAMPs) and, in particular, the high-mobility group box 1 (HMGB1). This molecule is released by damaged lung cells and can induce a robust innate immunity response. The increase in HMGB1 and NETosis could lead to sustained inflammation due to SARS-CoV-2 infection. Therefore, blocking these molecules might be useful in COVID-19 treatment and should be further studied in the context of targeted therapy.

Many researchers have speculated that the clinical progression from monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM) is driven by defects in dendritic cell (DC) function. However, evidence supporting this assumption is controversial, and no mechanism for the putative DC dysfunction has been demonstrated thus far. We studied DC subsets from the bone marrow of MM patients compared with those of MGUS patients and control subjects. We found that myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) accumulate in the bone marrow during the MGUS-to-MM progression. After engulfment of apoptotic tumor plasma cells via CD91, bone marrow mDCs and pDCs mature and are able to activate tumor-specific CD8(+) T cells. However, by interacting directly with CD28 on live (nonapoptotic) tumor plasma cells, bone marrow mDCs downregulate the expression of proteasome subunits in these cells, thus enabling their evasion from human leukocyte antigen (HLA) class I-restricted CD8(+) T-cell killing. These results suggest that DCs play a dual, but opposing, role in MM: for one, DCs activate CD8(+) T cells against tumor plasma cells and, for the other, DCs protect tumor plasma cells from CD8(+) T-cell killing. This information should be taken into account in designing immunotherapy approaches to enhance immune surveillance in MGUS and to break down immune tolerance in MM.

BACKGROUND: Hepatitis C virus (HCV) chronic infection is frequently associated to autoimmune manifestations. The aim of this study was to prospectively evaluate the occurrence of clinical and/or laboratory features of autoimmunity in a cohort of 140 consecutive HCV chronically infected patients treated with direct-acting antiviral agents (DAAs) and followed-up for 96 weeks. METHODS: All patients were screened for cryoglobulins, rheumatoid factor (RF), C3, C4, antinuclear antibody (ANA), anti-smooth muscle (ASMA), anti-liver kidney microsome type 1 (anti-LKM1), anti-mitochondrial antibodies (AMA), anti-neutrophil cytoplasmic antibodies (ANCA), and anti-liver cytosol type 1/soluble liver antigen (anti-LC1/SLA) autoantibodies before therapy and 12, 48 and 96 weeks after treatment. They were then grouped according to the expression of laboratory findings and related autoimmune diseases. RESULTS: At baseline, autoimmune manifestations were found in 70 patients: 83% of them were cryoglobulinemic, whereas ANA, AMA, perinuclear ANCA (pANCA) and LKM/LC1 autoantibodies were found in the remaining 17%. An autoimmune disease was diagnosed in 9 cases, two of them featuring an autoimmune liver disease (AILD). At the end of follow-up, despite viral clearance and regression of vasculitis, cryoglobulins persisted in 12 patients (21%), and autoantibodies disappeared or decreased in most of cases but, with the exception of the 2 patients diagnosed as AILD, associated autoimmune diseases remained stable. In one patient with relapsing cryoglobulinemia and ANA positivity, type-1 autoimmune hepatitis was defined. Conversely, autoantibodies first appeared after viral clearance in 5 patients, of whom one was diagnosed with type-1 autoimmune hepatitis and one with pANCA+ primary sclerosing cholangitis. CONCLUSIONS: Following DAA-induced viral clearance, cryoglobulins may persist or reappear. Autoantibodies changed dynamically in step with the disappearance of a previously diagnosed or the occurrence of a new AILD. A longer follow-up will be necessary to establish the possible diagnosis of a newly onset AILD, the reactivation of cryoglobulinemic vasculitis and even its progression to non-Hodgkin lymphoma.

INTRODUCTION: Lung ultrasound (LUS) is widely used in clinical practice for identifying interstitial lung diseases (ILDs) and assessing their progression. Although high-resolution computed tomography (HRCT) remains the gold standard for evaluating the severity of ILDs, LUS can be performed as a screening method or as a follow-up tool post-HRCT. Minimum training is needed to better identify typical lesions, and the integration of innovative artificial intelligence (AI) automatic algorithms may enhance diagnostic efficiency. AIM: This study aims to assess the effectiveness of a novel AI algorithm in automatic ILD recognition and scoring in comparison to an expert LUS sonographer. The "SensUS Lung" device, equipped with an automatic algorithm, was employed for the automatic recognition of the typical ILD patterns and to calculate an index grading of the interstitial involvement. METHODS: We selected 33 Caucasian patients in follow-up for ILDs exhibiting typical HRCT patterns (honeycombing, ground glass, fibrosis). An expert physician evaluated all patients with LUS on twelve segments (six per side). Next, blinded to the previous evaluation, an untrained operator, a non-expert in LUS, performed the exam with the SensUS device equipped with the automatic algorithm ("SensUS Lung") using the same protocol. Pulmonary functional tests (PFT) and DLCO were conducted for all patients, categorizing them as having reduced or preserved DLCO. The SensUS device indicated different grades of interstitial involvement named Lung Staging that were scored from 0 (absent) to 4 (peak), which was compared to the Lung Ultrasound Score (LUS score) by dividing it by the number of segments evaluated. Statistical analyses were done with Wilcoxon tests for paired values or Mann-Whitney for unpaired samples, and correlations were performed using Spearman analysis; p < 0.05 was considered significant. RESULTS: Lung Staging was non-inferior to LUS score in identifying the risk of ILDs (median SensUS 1 [0-2] vs. LUS 0.67 [0.25-1.54]; p = 0.84). Furthermore, the grade of interstitial pulmonary involvement detected with the SensUS device is directly related to the LUS score (r = 0.607, p = 0.002). Lung Staging values were inversely correlated with forced expiratory volume at first second (FEV1%, r = -0.40, p = 0.027), forced vital capacity (FVC%, r = -0.39, p = 0.03) and forced expiratory flow (FEF) at 25th percentile (FEF25%, r = -0.39, p = 0.02) while results directly correlated with FEF25-75% (r = 0.45, p = 0.04) and FEF75% (r = 0.43, p = 0.01). Finally, in patients with reduced DLCO, the Lung Staging was significantly higher, overlapping the LUS (reduced median 1 [1-2] vs. preserved 0 [0-1], p = 0.001), and overlapping the LUS (reduced median 18 [4-20] vs. preserved 5.5 [2-9], p = 0.035). CONCLUSIONS: Our data suggest that the considered AI automatic algorithm may assist non-expert physicians in LUS, resulting in non-inferior-to-expert LUS despite a tendency to overestimate ILD lesions. Therefore, the AI algorithm has the potential to support physicians, particularly non-expert LUS sonographers, in daily clinical practice to monitor patients with ILDs. The adopted device is user-friendly, offering a fully automatic real-time analysis. However, it needs proper training in basic skills.
ABSTRACT
Patients with multiple myeloma (MM) have an increased risk of sepsis due to underlying disease- and treatment-related immunosuppression. However, data on sepsis incidence, causative pathogens, and impact on outcomes in newly diagnosed MM (NDMM) are limited. We conducted a retrospective observational study of 92 NDMM patients who developed sepsis between 2022 and 2023 at a tertiary care center in Italy. Patient characteristics, sepsis criteria [Quick Sequential Organ Failure Assessment, Systemic Inflammatory Response Syndrome (SIRS)], microbiology results, and associations with progression-free survival (PFS) were analyzed. In this cohort of 92 critically-ill patients, pathogenic organisms were identified via microbiological culture in 74 cases. However, among the remaining 18 culture-negative patients, 9 exhibited a SIRS score of 2 and another 9 had a SIRS score of 4, suggestive of a clinical presentation consistent with sepsis despite negative cultures. Common comorbidities included renal failure (60%), anemia (71%), and bone disease (83%). Gram-negative (28%) and Gram-positive (23%) bacteria were frequent causative organisms, along with fungi (20%). Cox Univariate analyses for PFS showed statically significant HR in patients with albumin ≥ 3.5 vs < 3.5 (HR = 5.04, p < 0.001), Karnofsky performance status ≥ 80 vs < 80 (HR = 2.01, p = 0.002), and early-stage vs late-stage disease by International Staging System (HR = 4.76 and HR = 12.52, both p < 0.001) and Revised International Staging System (R-ISS III vs R-ISS I, HR = 7.38, p < 0.001). Sepsis is common in NDMM and associated with poor outcomes. Risk stratification incorporating sepsis severity, comorbidities, and disease stage may help guide preventive strategies and optimize MM management.

Over the past few years, COVID-19 pandemic has imposed a high toll worldwide, with a high burden of morbidity and mortality. Healthcare practitioners (HCPs) have been in the frontline since the beginning of the outbreak, and the high level of stress have affected their physical and mental status, as well as their relationships. We aimed at exploring the self-reported changes in comprehensive well-being in a cohort of Italian physicians. An online-based survey was administered to the members of the Italian Society of Internal Medicine (SIMI) between March and June 2021. The survey was based on 32 multiple-choice questions exploring self-reported physical and mental well-being, as well as changes in workloads, work-related feelings and physicians' relationship with patients, colleagues and families. 228 physicians (mean age: 35.7 ± 9.8 years) participated in the survey; 120 (52.6%) were residents, 196 (86.0%) worked in COVID-19 units and 65 (28.5%) had COVID-19 during the pandemic. A significant proportion of respondents reported to have experience onset or worsening of physical and mental symptoms, with insomnia/sleep disorders (58.3%) and mood swings (47.8%) being the most common, respectively. The burden of physical and mental consequences was broadly higher among residents compared to specialists, with the former reporting more frequently an increase in the number of worked hours (p = 0.020) and being more frequently infected with COVID-19 (35.0% vs. 21.3, p = 0.032). Moreover, familiar and doctor-patient relationships were also considerably affected. Physicians have been suffering a wide spectrum of physical, mental and relational consequences during COVID-19 pandemic, with youngest doctors being more likely to present several physical and mental health symptoms. Further studies are needed to evaluate long-term consequences of COVID-19 pandemic on the well-being of HCPs, and potential preventive strategies.

Alcoholic beverages are common components of diets worldwide and understanding their effects on humans' health is crucial. Because hypertension is the leading risk factor for cardiovascular diseases and all-cause mortality, the relationship of alcohol consumption with blood pressure (BP) has been the subject of extensive investigation. For the purpose of this review, we searched the terms "alcohol", "ethanol", and "arterial hypertension" on Pubmed MeSH and selected the most relevant studies. Short-term studies showed a biphasic BP response after ingestion of high doses of alcohol, and sustained alcohol consumption above 30 g/day, significantly, and dose-dependently, increased the risk for hypertension. These untoward effects of alcoholic beverages on BP can be mediated by a multiplicity of neurohormonal mechanisms. In addition to the effects on BP, excess alcohol intake might contribute to cardiac and renal hypertensive organ damage, although some studies suggest possible benefits of moderate alcohol consumption on additional cardiovascular risk factors, such as diabetes and lipoprotein(a). Some intervention studies and cumulative analyses support the evidence of a benefit of the reduction/withdrawal of alcohol consumption on BP and cardiovascular outcomes. This is why guidelines of scientific societies recommend avoidance or limitation of alcohol intake below one unit/day for women and two units/day for men. This narrative article overviews all these topics, providing an update of the current knowledge on the relationship between alcohol and BP.

We identified STAT1 gain of function (GOF) in a 32-year-old female with pallor, weakness, cough, and dyspnea admitted to our Division of Medicine. She had severe oral ulcers (OU), type 1 diabetes (T1DM), and pancytopenia. Bone marrow (BM) biopsy showed the absence of erythroid precursors. Peripheral blood parameters such as neutrophils < 500/mL, reticulocytes < 2%, and BM hypo-cellularity allowed to diagnose severe aplastic anemia. A heterozygous variant (p.520T>C, p.Cys174Arg) of STAT1 was uncovered. Thus, p.Cys174Arg mutation was investigated as potentially responsible for the patient's inborn immunity error and aplastic anemia. Although STAT1 GOF is rare, aplastic anemia is a more common condition; therefore, we explored STAT1 functional role in the pathobiology of BM failure. Interestingly, in a cohort of six patients with idiopathic aplastic anemia, enhanced phospho-STAT1 levels were observed on BM immunostaining. Next, the most remarkable features associated with STAT1 signaling dysregulation were examined: in both pure red cell aplasia and aplastic anemia, CD8+ T cell genetic variants and mutations display enhanced signaling activities related to the JAK-STAT pathway. Inborn errors of immunity may represent a paradigmatic condition to unravel crucial pathobiological mechanisms shared by common pathological conditions. Findings from our case-based approach and the phenotype correspondence to idiopathic aplastic anemia cases prompt further statistically powered prospective studies aiming to elucidate the exact role and theragnostic window for JAK/STAT targeting in this clinical context. Nonetheless, we demonstrate how a comprehensive study of patients with primary immunodeficiencies can lead to pathophysiologic insights and potential therapeutic approaches within a broader spectrum of aplastic anemia cases.

Granulomatosis with polyangiitis (GPA) is an ANCA-associated small-vessel vasculitis. Vessel wall inflammation induces multiple vascular damages, leading to accelerated atherosclerosis. Metabolic profile and cardiovascular risk are somewhat understood in GPA patients. Cardiovascular atherosclerotic disease (ASCVD) may represent a risk for outcomes. Our purpose is to evaluate ASCVD risk in GPA patients. Thirty-six patients received GPA diagnosis (T0) and were evaluated after 1 (T1) and 2 (T2) years follow-up. All patients were treated with high-dose glucocorticoid, one-year tapered, along with immunosuppressants. Total cholesterol significantly increased in T1 vs. T0 and T2. LDL exhibited the same trend, while triglycerides increased in both T1 and T2 vs. T0. No difference was found in HDL. A significant hsCRP decrease was detected at T1 and T2 vs. T0, but not between T2 and T1. Moreover, we found a significant reduction in ESR at T2 compared with T1 and T0 and at T1 compared to T0. Hypertensive patients presented a pronounced increase in lipids, while inflammation reduced slowly compared to normotensives. Our data suggest that the increase in cholesterol and LDL in T1 is a consequence of glucocorticoids. These data can be useful in the evaluation of both CV diseases and lipid metabolism, which are closely related to vessel inflammation.
ABSTRACT
Heart failure (HF) is a clinical syndrome consisting of typical symptoms and signs due to structural and/or functional abnormalities of the heart, resulting in elevated intracardiac pressures and/or inadequate cardiac output. The vascular system plays a crucial role in the development and progression of HF regardless of ejection fraction, with endothelial dysfunction (ED) as one of the principal features of HF. The main ED manifestations (i.e., impaired endothelium-dependent vasodilation, increased oxidative stress, chronic inflammation, leukocyte adhesion, and endothelial cell senescence) affect the systemic and pulmonary haemodynamic and the renal and coronary circulation. The present review is aimed to discuss the contribution of ED to HF pathophysiology-in particular, HF with preserved ejection fraction-ED role in HF patients, and the possible effects of pharmacological and non-pharmacological approaches. For this purpose, relevant data from a literature search (PubMed, Scopus, EMBASE, and Medline) were reviewed. As a result, ED, assessed via venous occlusion plethysmography or flow-mediated dilation, was shown to be independently associated with poor outcomes in HF patients (e.g., mortality, cardiovascular events, and hospitalization due to worsening HF). In addition, SGLT2 inhibitors, endothelin antagonists, endothelial nitric oxide synthase cofactors, antioxidants, and exercise training were shown to positively modulate ED in HF. Despite the need for future research to better clarify the role of the vascular endothelium in HF, ED represents an interesting and promising potential therapeutic target.
ABSTRACT
COVID-19 induces endotheliitis and one of the main complications is enhanced coagulation. The incidence of pulmonary embolism (PE) in COVID-19 (CPE) has increased and clinical features for a rigorous analysis still need to be determined. Thus, we evaluated the clinical characteristics in CPE and the immune infiltration that occurred. Between January 1 and December 31, 2021, 38 patients were affected by CPE (9 ICU, 19 males/19 females, 70.18 ± 11.24 years) out of 459 COVID-19 cases. Controls were subjects who were evaluated for PE between January 1 2015, and December 31, 2019 (92 patients, 9 ICU, 48 males/45 females, 69.55 ± 16.59 years). All patients underwent complete physical examination, pulmonary computed tomography, laboratory tests, D-dimer, and blood gas analysis. There were no differences in laboratory tests or D-dimer. In patients with CPE, pO2, alveolar-arterial oxygen difference (A-aDO2), oxygen saturation %, and the ratio between arterial partial pressure of oxygen (PaO2) and fraction of inspired oxygen (FiO2), P/F, were significantly increased. There were no differences in PaCO2. Platelet count was inversely correlated to P/F (r = - 0.389, p = 0.02) but directly to A-aDO2 (r = 0.699, p = 0.001) only in patients with CPE. Histology of lung biopsies (7 CPE/7 controls) of patients with CPE showed an increase in CD15+ cells, HMGB1, and extracellular MPO as a marker of NETosis, while no significant differences were found in CD3+, CD4+, CD8+, and intracellular MPO. Overall, data suggest that CPE has a different clinical setting. Reduced oxygen content and saturation described in Patients with CPE should not be considered a trustworthy sign of disease. Increased A-aDO2 may indicate that CPE involves the smallest vessels as compared to classical PE. The significant difference in NETosis may suggest the mechanism related to thrombi formation.

Oxidative stress (OS) is one of the most frequently recognized causes of ageing. Telomere erosion, defects in the DNA damage response and alterations in the nuclear architecture are also associated with premature ageing. The most severe premature ageing syndrome, Hutchinson-Gilford progeria syndrome (HGPS) is associated with alterations in nuclear shape resulting in the deregulation of lamin A/C. In this review we describe emerging data reporting the role of OS and antioxidant defence in progeroid syndromes focusing on HGPS. We explore precise antioxidant defence mechanisms and related drugs that may create a potential path out of the woods in this disease. Pathways regulated by Nuclear factor E2 related factor (Nrf2), by Nuclear Factor kappa B (NF-kB), and related to the Unfolded Protein Response (UPR) and Endoplasmic Reticulum (ER) stress are under investigation in HGPS patients for which the goal is a significant lifespan extension in particular by postponing atherosclerosis-related complications.
