Some features of vitamin D content in arterial hypertension in patients with and without osteoarthritis of the knee joints

The aim of the study was to assess the relationship of serum vitamin D concentration with impaired cardiometabolic profile in hypertension in patients with and without osteoarthritis of the knee joints.Materials and methods. The results of the examination of 196 patients aged 54.06±9.4 years with arterial hypertension (AH) were analyzed, who were divided into groups depending on the presence of osteoarthritis of the knee joints (OA KS): 1st–patients with AH (n=153) and 2nd–patients with AH+OA KS (n=43).All patients were assessed for the level of 25 (OH) D, biochemical parameters of blood plasma (total cholesterol, low and high density lipoproteins, triglycerides, creatinine), cardiac morphometry using ECHOCG.Results. The proportion of people with adequate vitamin D levels was 1.2 times higher among patients with AH+OA CS (32.6 % vs. 26.1 %, p0.05). Additional vitamin D supplementation was significantly more common in the group of patients with AH+OA (0 % vs. 44 %, p<0.001).The subgroup with vitamin D deficiency in patients with hypertension without OA CS had the most unfavorable «cardiometabolic» profile (they had significantly high BMI, total cholesterol, and LVH).Conclusions. In people with arterial hypertension (without OA CS), violations of vitamin D levels (deficiency or insufficiency) are associated with an unfavorable «cardio-metabolic» profile – they need additional testing of vitamin D levels in the blood and correction of the detected violations. The presence of pathology of the musculoskeletal system (OA CS) in patients with arterial hypertension, it had no effect on the level of vitamin D and the frequency of its individual disorders. However, in this cohort of patients (AH+OA), the use of vitamin D supplements was significantly more common (0 % vs. 44 %, p<0.001). The assessment of the effect of vitamin D supplementation on cardiometabolic status deserves further investigation. Patients with arterial hypertension and its combination with comorbid pathology have, on average, vitamin D levels classified as insufficiency.

ATP13A3 variants promote pulmonary arterial hypertension by disrupting polyamine transport

Abstract Aims Potential loss-of-function variants of ATP13A3, the gene encoding a P5B-type transport ATPase of undefined function, were recently identified in pulmonary arterial hypertension (PAH) patients. ATP13A3 is implicated in polyamine transport but its function has not been fully elucidated. Here, we sought to determine the biological function of ATP13A3 in vascular endothelial cells and how PAH-associated variants may contribute to disease pathogenesis. Methods and Results We studied the impact of ATP13A3 deficiency and overexpression in endothelial cell (EC) models (human pulmonary ECs, blood outgrowth ECs (BOECs) and HMEC-1 cells), including a PAH patient-derived BOEC line harbouring an ATP13A3 variant (LK726X). We also generated mice harbouring an Atp13a3 variant analogous to a human disease-associated variant to establish whether these mice develop PAH. ATP13A3 localised to the recycling endosomes of human ECs. Knockdown of ATP13A3 in ECs generally reduced the basal polyamine content and altered the expression of enzymes involved in polyamine metabolism. Conversely, overexpression of wild-type ATP13A3 increased polyamine uptake. Functionally, loss of ATP13A3 was associated with reduced EC proliferation, increased apoptosis in serum starvation and increased monolayer permeability to thrombin. Assessment of five PAH-associated missense ATP13A3 variants (L675V, M850I, V855M, R858H, L956P) confirmed loss-of-function phenotypes represented by impaired polyamine transport and dysregulated EC function. Furthermore, mice carrying a heterozygous germ-line Atp13a3 frameshift variant representing a human variant spontaneously developed a PAH phenotype, with increased pulmonary pressures, right ventricular remodelling and muscularisation of pulmonary vessels. Conclusion We identify ATP13A3 as a polyamine transporter controlling polyamine homeostasis in ECs, deficiency of which leads to EC dysfunction and predisposes to PAH. This suggests a need for targeted therapies to alleviate the imbalances in polyamine homeostasis and EC dysfunction in PAH.

Serum PM20D1 levels in patients with idiopathic pulmonary arterial hypertension and its clinical significance

ObjectiveThis study aimed to investigate the serum levels of Peptidase M20 domain containing 1 (PM20D1) in idiopathic pulmonary arterial hypertension (IPAH) patients and examine its association with lipid metabolism, echocardiography, and hemodynamic parameters.MethodsThis prospective observational research enrolled 103 IPAH patients from January 2018 to January 2022. Enzyme-linked immunosorbent assay (ELISA) was used to measure the serum PM20D1 levels in all patients before treatment within 24 h of admission. Demographic data, echocardiography, hemodynamic parameters and serum biomarkers were also collected.ResultsThe IPAH patients in the deceased group had significantly elevated age, right atrial (RA), mean pulmonary arterial pressure (mPAP), mean right atrial pressure (mRAP), pulmonary capillary wedge pressure (PCWP), pulmonary vascular resistance (PVR) and significantly decreased 6 min walking distance (6MWD) and tricuspid annulus peak systolic velocity (TASPV). IPAH patients showed significant decreases in serum PM20D1, low-density lipoprotein cholesterol (LDL-C), and albumin (ALB). Additionally, PM20D1 was negatively correlated with RA, NT-proBNP and positively correlated with PVR, ALB, 6MWD, and TAPSV. Moreover, PM20D1 has the potential as a biomarker for predicting IPAH patients’ prognosis. Finally, logistic regression analysis indicated that PM20D1, ALB, NT-proBNP, PVR, TASPV, RA and 6MWD were identified as risk factors for mortality in IPAH patients.ConclusionOur findings indicated that the serum levels of PM20D1 were significantly decreased in IPAH patients with poor prognosis. Moreover, PM20D1 was identified as a risk factor associated with mortality in IPAH patients.

Thiazide-associated hyponatremia in arterial hypertension patients: A nationwide population-based cohort study.

Thiazides are the first-line treatment for hypertension, however, they have been associated with hospitalizations for thiazide-associated hyponatremia (TAH). The aim of this study was to evaluate the risk of TAH and other drug-associated hyponatremia in a Korean population. The study used big data from the National Health Insurance Sharing Service of 1,943,345 adults treated for hypertension from January 2014 to December 2016. The participants were divided into two groups based on the use of thiazides. Cox proportional hazard models were used to identify independent risk factors for the occurrence of hyponatremia. The study found that hyponatremia-related hospitalizations were significantly higher in the thiazide group than the control group (2.19%vs. 1.45%). The risk increased further with concurrent use of other diuretics or desmopressin, and thiazide+spironolactone+desmopressin and hospitalization risk further increased (4.0 and 6.9 times). Multivariate analysis showed that hyponatremia occurrence increased with age, diabetes mellitus, depression, and thiazide use (hazard ratio=1.436, p<0.001). The thiazide group had better 6-year overall survival than the control group but had more fractures and hyponatremia. Thiazide use is associated with an increased risk of hyponatremia and related complications. However, the mortality rate decreased in those who received thiazides, suggesting that thiazide use itself is not harmful and may help decrease complications and improve prognosis with proper, cautious use in high-risk patients.

Collagen triple helix repeat-containing protein 1 is a novel biomarker of right ventricular involvement in pulmonary hypertension

BackgroundPulmonary hypertension leads to right ventricular failure, which is a major determinant of prognosis. Circulating biomarkers for right ventricular function are poorly explored in pulmonary hypertension. This study aimed to clarify the significance of collagen triple helix repeat-containing protein 1 (CTHRC1) as a biomarker of right ventricular failure in pulmonary hypertension. MethodsA monocrotaline-induced pulmonary hypertension rat model was used to evaluate right ventricular CTHRC1 expression and its relationship with fibrosis. Next, human plasma CTHRC1 levels were measured in controls (n = 20), pulmonary arterial hypertension (n = 46), and chronic thromboembolic pulmonary hypertension (CTEPH) patients (n = 64) before the first and after the final balloon pulmonary angioplasty. ResultsCTHRC1 expression was higher in the right ventricles of rats with monocrotaline-induced pulmonary hypertension than in those of controls. CTHRC1 was co-localized with vimentin and associated with fibrosis in the right ventricles. Plasma CTHRC1 levels were higher in human pulmonary arterial hypertension (P = 0.006) and CTEPH patients (P = 0.011) than in controls. Plasma CTHRC levels were correlated with B-type natriuretic peptide (R = 0.355, P < 0.001), tricuspid lateral annular peak systolic velocity (R = -0.213, P = 0.029), and right ventricular fractional area change (R = -0.225, P = 0.017). Finally, plasma CTHRC1 levels were decreased after the final balloon pulmonary angioplasty (P < 0.001) in CTEPH. ConclusionsCTHRC1 can be a circulating biomarker associated with right ventricular function and fibrosis in pulmonary hypertension and might reflect the therapeutic efficacy of balloon pulmonary angioplasty in CTEPH.

A Case Report: A Successful Management of Extrinsic Compression of the Left Main Coronary Artery by a Dilated Pulmonary Artery in Patients with Pulmonary Arterial Hypertension

Extrinsic compression of the left main coronary artery (LMCA) by a dilated pulmonary artery can be life threatening in pulmonary arterial hypertension patients; however, it can be treated with percutaneous coronary intervention. In this case report, we presented a successful treatment with the stenting of the LMCA stenosis associated with extrinsic compression of LMCA by a dilated pulmonary artery.

An Increase in the Left Atrium Volume During Exercise is Associated With a Positive Result of a Diastolic Stress Test in Patients With Arterial Hypertension.

To study the relationship between changes in left atrial volume (LAV) during exercise and the result of a diastolic stress test (DST) in patients with arterial hypertension (AH). The study included 219 patients with AH without ischemic heart disease and atrial fibrillation. During the DST performed before and after exercise, the ratio of transmitral flow velocity to mitral annular velocity (E/e'), the left atrial global longitudinal strain in the reservoir phase (reservoir strain), and LAV were determined. The criterion for a positive DST was an increase in E/e' ≥15. A positive result of DST was observed in 90 (41.1%) patients. Patients with positive DST were older (65.0 and 59.0 years); among them, there were fewer men (24.4 and 41.1%), but more patients with obesity (66.7 and 40.3%) and diabetes mellitus (36.7 and 8.5%). At rest, patients with positive DST had higher E/e' ratio (11.5 and 8.8), pulmonary artery systolic pressure (29.0 and 27.0 mm Hg), and LAV (60.0 and 52.0 ml), but a lower left atrial reservoir strain (20.0 and 24.0%). During exercise in patients with positive and negative DST, E/e' increased by 5.46 and 0.47 units, respectively. Changes in the LAV and reservoir strain during exercise in these groups were directed differently. In patients with positive DST, the left atrial reservoir strain decreased by 1.0 percentage points (pp) whereas in patients with negative DST, it increased by 8.0 pp. During exercise, the LAV increased by 10.0 ml in patients with a positive DST, whereas in the alternative group, the LAV decreased by 8.5 ml. The AUC for changes in LAV as an indicator of a positive DST was 0.987 while the AUC for the resting left atrial reservoir strain was 0.938. An increase in LAV &gt;1 ml, as an indicator of a positive DST has a sensitivity of 96.9% and a specificity of 95.1%. In AH patients, changes in left ventricular filling pressure are associated with a unidirectional change in LAV. An increase in LAV during exercise by more than 1 ml can serve as a criterion for a positive DST result. This assessment was consistent with the assessment of the DST result by the E/e' criterion &gt;15 in 94.5% of cases.

Strategies for choosing combination therapy for hypertension in metabolic syndrome - focus on inflammation

The article substantiates the need for adequate fixed combination therapy for metabolic syndrome and arterial hypertension (AH). The issues of inflammation in the initiation and stabilization of arterial hypertension in patients with metabolic syndrome (MS) are considered. Taking into account the results of international and Russian studies, a differentiated approach is proposed to select a fixed combination of antihypertensive drugs for the treatment of hypertension and prevention of cardiovascular complications in patients with MS.

Clinical Correlates of a Nonplexiform Vasculopathy in Patients With a Diagnosis of Idiopathic Pulmonary Arterial Hypertension

The clinical phenotype of idiopathic pulmonary arterial hypertension (IPAH) patients has changed. . Whether or not subgroups of IPAH patients have different vascular phenotypes is a subject of debate. What are the histological patterns and their clinical correlates in patients diagnosed with IPAH or hereditary PAH? In this this cross-sectional registry study lung histology of 50 IPAH patients was qualitatively assessed by two experienced pathologists. In addition, quantitative analysis by means of histopathological morphometry using immunohistochemistry was performed. Histopathological characteristics were correlated with clinical and hemodynamic parameters. In this cohort of 50 IPAH patients, a plexiform vasculopathy was observed in 26/50 (52%) of patients, while 24/50 (48%) patients had a non-plexiform vasculopathy. The non-plexiform vasculopathy was characterized by prominent pulmonary microvascular (arterioles and venules) remodeling and vascular rarefaction. While hemodynamic parameters were comparable in plexiform versus non-plexiform vasculopathy, patients with non-plexiform vasculopathy were older, more often male, had a stronger history of cigarette smoking and lower diffusing capacity for carbon monoxide (DLCO) at diagnosis No mutations in established PAH genes were found in the non-plexiform group. This study reveals different vascular phenotypes within the current spectrum of patients diagnosed with IPAH, separated by clinical characteristics (age, sex, , history of cigarette smoking, and DLCO at diagnosis). Potential differences in underlying pathobiological mechanisms between patients with plexiform and non-plexiform / microvascular disease should be taken into account in future research strategies unravelling the pathophysiology of pulmonary hypertension and developing biology-targeted treatment approaches.

Hemodynamic and Clinical Profiles of Pulmonary Arterial Hypertension Patients with GDF2 and BMPR2 Variants.

Asians have a higher carrier rate of pulmonary arterial hypertension (PAH)-related genetic variants than Caucasians do. This study aimed to identify PAH-related genetic variants using whole exome sequencing (WES) in Asian idiopathic and heritable PAH cohorts. A WES library was constructed, and candidate variants were further validated by polymerase chain reaction and Sanger sequencing in the PAH cohort. In a total of 69 patients, the highest incidence of variants was found in the BMPR2, ATP13A3, and GDF2 genes. Regarding the BMPR2 gene variants, there were two nonsense variants (c.994C>T, p. Arg332*; c.1750C>T, p. Arg584*), one missense variant (c.1478C>T, p. Thr493Ile), and one novel in-frame deletion variant (c.877_888del, p. Leu293_Ser296del). Regarding the GDF2 variants, there was one likely pathogenic nonsense variant (c.259C>T, p. Gln87*) and two missense variants (c.1207G>A, p. Val403Ile; c.38T>C, p. Leu13Pro). The BMPR2 and GDF2 variant subgroups had worse hemodynamics. Moreover, the GDF2 variant patients were younger and had a significantly lower GDF2 value (135.6 ± 36.2 pg/mL, p = 0.002) in comparison to the value in the non-BMPR2/non-GDF2 mutant group (267.8 ± 185.8 pg/mL). The BMPR2 variant carriers had worse hemodynamics compared to the patients with the non-BMPR2/non-GDF2 mutant group. Moreover, there was a significantly lower GDF2 value in the GDF2 variant carriers compared to the control group. GDF2 may be a protective or corrected modifier in certain genetic backgrounds.

Treatment of pulmonary arterial hypertension in patients with connective tissue diseases: a systematic review and meta-analysis

The evidence for the treatment of connective tissue disease-associated pulmonary arterial hypertension (CTD-PAH) mostly depends on subgroup or post hoc analysis of randomized controlled trials (RCTs). Thus, we performed a meta-analysis of RCTs that reported outcomes for CTD-PAH. PubMed and EMBASE were searched for CTD-PAH treatment. The selected outcomes were functional class (FC) change, survival rates, 6-min walk distance (6-MWD), clinical worsening (CW), N-terminal prohormone BNP (NT-proBNP), pulmonary vascular resistance (PVR), mean pulmonary arterial pressure (mPAP), right atrial pressure (RAP), and cardiac index (CI). The meta-analysis was conducted according to the PRISMA guidelines and registered in PROSPERO (CRD42020153560). Twelve RCTs conducted with 1837 patients were included. The diagnoses were systemic sclerosis in 59%, SLE in 20%, and other CTDs in 21%. The pharmacological interventions were epoprostenol, treprostinil, sildenafil, tadalafil, bosentan, macitentan, ambrisentan, riociguat, and selexipag. There was a significant difference between interventions and placebo in FC, 6MWD, CW, PVR, RAP, and CI that favored intervention. Our analysis showed a 39% reduction in the CW risk with PAH treatment. The short-term survival rates and mean serum NT-proBNP changes were similar between the study and control groups. Treatment for CTD-PAH had favorable effects on clinical and hemodynamic outcomes but not on survival and NT-proBNP levels. Different from the previous meta-analyses that focused on 6-MWD, time to clinical worsening, and CW as outcomes, this meta-analysis additionally reports the pooled analysis of change in FC, hemodynamic measurements (RAP, PVR, CI), and NT-proBNP, some of which have prognostic value for PAH.

Occurrence of Arterial Hypertension in Patients with sleep Apnoea Syndrome

Introduction: Sleep apnoea syndrome (SAS) is a serious under-diagnosed chronic disease, which often coincides with arterial hypertension (AH). The U.S. Joint National Committee considers SAS to be the most common cause of secondary arterial hypertension. Objective: To determine the incidence of arterial hypertension in patients diagnosed with SAS in an accredited sleep laboratory (ASL) in Bratislava in the years 2013-2022. Methods: The monitored group consisted of 688 patients examined in an ASL in Bratislava who underwent an initial examination (anamnesis, anthropometry, sleep questionnaire) and a diagnosis of sleep-disordered breathing (nocturnal polysomnography) in order to confirm or refute the diagnosis of OSAS. Data collection also took place by using a copy of the patients’ medical records (presence of AH). We used Microsoft Excel and statistical software SPSS, version 21.0 to process the obtained data. We considered the result to be statistically significant if p ≤ 0.05. Results: We demonstrated a statistically significant difference in the incidence of AH in patients with SAS compared to patients without SAS, i.e., there was a statistically significantly higher incidence of AH in patients with SAS compared to patients without SAS (39% vs. 17.5%; OR=3.0; p&lt;0.001). We also demonstrated that the higher the AHI value in patients with SAS, the higher the incidence of AH (p=0.002; 95% CI 1.4 – 4.4). In addition, there was a 1.9 times higher risk of developing AH in patients with a moderate degree of SAS compared to patients with a mild degree of SAS (p=0.014) and up to a 2.8 times higher risk of developing AH in patients with a severe degree of SAS compared to patients with moderate SAS (p&lt;0.001) regardless of BMI. Conclusion: Due to the high coincidence (1/3) of arterial hypertension and sleep apnoea syndrome in the monitored group, it is necessary to focus on effective screening of SAS in high-risk persons as well as effective screening of SAS in persons with present AH.

Possibilities of Using the National Electronic Data Syetstem in Assessing the Control of Arterial Hypertension at The Primary Health Care Level in the Kyrgyz Republic Using the Example of a Single Family Medicine Center.

To determine the capabilities of the National Electronic System for collecting quantitative data necessary to assess the quality of management and effectiveness of arterial hypertension (AH) control at the primary health care (PHC) level and to develop indicators and possibilities of their use for a standardized report on the quality of AH management and control at the PHC level in the Kyrgyz Republic. Data from electronic outpatient records were processed for all registered patients of a pilot family medicine center (FMC) that was selected randomly. The registered patient group consisted of 91,226 people older than 18 years, including 37,740 men and 53,486 women. The data obtained during contact with a patient was entered by the family doctor into the electronic outpatient record and automatically forwarded to the center that collected and aggregated the data. To monitor AH control, 11 indicators were developed and evaluated. The indicators were divided into 3 groups: indicators for identifying AH, indicators for the quality of AH patient management, and indicators for the effectiveness of AH control. In total, 26,206 patients (7,933 men and 18,273 women) visited the FMC during a year, and blood pressure (BP) was measured in 71.4% of them. In 2022, 5,072 patients (5.6% of the registered group) visited the FMC for AH, including 1,539 men and 3,533 women (4.1 and 6.6% of the registered patient group, respectively; p&lt;0.001). The proportion of patients with AH who, according to the clinical protocol, had their BP measured 2 times a year or more, was 81.4% and was slightly higher for women than for men (82.3% and 79.1%, respectively; p&lt;0.01). 38.7% of AH patients received antihypertensive drugs. Lipid-lowering therapy was prescribed to 23.5% of AH patients. The proportion of AH patients taking acetylsalicylic acid was higher, 36.3% for the whole group, including 34.1% for men and 37.2% for women (p&lt;0.05). The efficacy of AH treatment was 62.8%. Any monitoring system has limitations for the amount of useful data that can be obtained ensuring their proper quality. Taking this into account, two major indicators are suggested to use for evaluating the effectiveness of AH control at the PHC level: 1) the number of AH patients who have achieved the BP goal; 2) the number of AH patients who visited a medical institution (health care facility) during a calendar year relative to the number of registered patients (AH detectability).

Effect of Macitentan in Pulmonary Arterial Hypertension and the Relationship Between Echocardiography and cMRI Variables: REPAIR Echocardiography Sub-study Results.

The aim of this sub-study was to evaluate the relationship between echocardiography (echo) and cardiac magnetic resonance imaging (cMRI) variables and to utilize echo to assess the effect of macitentan on right ventricle (RV) structure and function. REPAIR (NCT02310672) was a prospective, multicenter, single-arm, open-label, 52-week, phase 4 study in pulmonary arterial hypertension (PAH) patients, which investigated the effect of macitentan 10mg as monotherapy, or in combination with a phosphodiesterase 5 inhibitor, on RV structure, function, and hemodynamics using cMRI and right heart catheterization. In this sub-study, patients were also assessed by echo at screening and at weeks 26 and/or 52. Post hoc correlation analyses between echo and cMRI variables were performed using Pearson's correlation coefficient, Spearman's correlation coefficient, and Bland-Altman analyses. The Echo sub-study included 45 patients. Improvements in echo-assessed RV stroke volume (RVSV), left ventricular SV (LVSV), LV end-diastolic volume (LVEDV), RV fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), and in 2D global longitudinal RV strain (2D GLRVS) were observed at weeks 26 and 52 compared to baseline. There was a strong correlation between echo (LVSV, 2D GLRVS, and LVEDV) and cMRI variables, with a moderate correlation for RVSV. Bland-Altman analyses showed a good agreement for LVSV measured by echo versus cMRI, whereas an overestimation in echo-assessed RVSV was observed compared to cMRI (bias of -15mL). Hemodynamic and functional variables, as well as safety, were comparable between the Echo sub-study and REPAIR. A good relationship between relevant echo and cMRI parameters was shown. Improvements in RV structure and function with macitentan treatment was observed by echo, consistent with results observed by cMRI in the primary analysis of the REPAIR study. Echo is a valuable complementary method to cMRI, with the potential to non-invasively monitor treatment response at follow-up. REPAIR NCT02310672.

Epidemiology and Clinical Features of Arterial Hypertension in Patients with Type 2 Diabetes Mellitus. Literature Review

Hypertension and type 2 diabetes mellitus are often combined and mutually enhance the adverse effect on vascular and renal prognosis. Hypertension is present in about 50 % of patients with type 2 diabetes, and diabetes, in turn, is detected in about 20 % of people with hypertension. The risk of developing hypertension in patients with type 2 diabetes is 2-2.5 times higher than in people without diabetes; the presence of hypertension increases the risk of type 2 diabetes by the same number of times. Hypertension and diabetes mutually burden each other: on the one hand, the presence of hypertension significantly increases the likelihood of developing diabetic macro- and microvascular complications (including diabetic nephropathy and retinopathy); on the other hand, type 2 diabetes, as a classic independent cardiovascular risk factor, increases the risk of complications inherent in hypertension by about 2 times Careful treatment of diabetes with maintenance of target values of glycemia for a long time may be associated with a decrease in the likelihood of developing hypertension by 24 % compared with less adequate control of glycemia. Hypertension in type 2 diabetes may have a number of features that distinguish such patients from the general population of people with hypertension. Such features include a higher proportion of isolated systolic hypertension and resistant hypertension, certain types of circadian rhythm disorders of blood pressure (categories “non-dipper” and “night-peaker”), frequent combination with albuminuria, frequent high salt sensitivity and volume-dependent nature of hypertension, and others.

Epidemiological and clinical analysis of exposure-related factors in non-melanoma skin cancer: A retrospective cohort study

BackgroundThe incidence of non-melanoma skin cancers (NMSCs) increased over last decades, probably due to environmental concerns or to the increase of frail patients with age related comorbidities. Currently, the relationship of increasing global skin cancer rates with increased ultraviolet radiations (UVRs) resulting from stratospheric ozone depletion, global warming, and air pollution from fossil-fuel combustion. AimsWe conducted a retrospective epidemiological study including 546 NMSC patients managed at the Dermatology Unit of the Tor Vergata Hospital to highlight different trends of sun exposure or different comorbidities. MethodsDescriptive and inferential statistical analyses were performed to evidence differences between continous variable and Spearman rank test for dicotomical variables. Charlson Comorbidity Index was calculated to obtain the 10-years survival rate in order to identify the mean comorbidity burden of our patients. ResultsConsidering patients with comorbidities (73.81%), actinic keratoses (AKs) was the most frequent lesion. In patients with a history of previous melanoma, basal cell carcinoma (BCC) was predominant (ANOVA test, p < 0.05) with a statistically significant correlation (rho = 0.453; p < 0.01). Squamous cell carcinoma (SCC) showed a higher rate in arterial hypertension patients, followed by the chronic heart failure and hematologic neoplasms (60%, 29.7% and 32.1%, respectively) groups. Men were more affected than women, representing 61.54% of patients. Chronic sun exposure is directly correlated with SCC rho = 0.561; p < 0.01), whereas BCC correlated with a history of sunburns (rho = 0.312; p < 0.05). ConclusionsHistory of photo-exposition had an important role on NMSC development especially for work or recreational reasons. Sex, age, and presence of comorbidities influenced different NMSC types. BCC was more frequent in younger patients, associated with melanoma and sunburns. The presence of SCC is associated with older patients and the hypertension group. AKs were diagnosed predominantly in oldest men, with a chronic sun-exposure history, and hematologic neoplasms group.
