Thickness of carotid intima and epicardial fat in rosacea: a cross-sectional study

Evaluation of atherosclerotic risk in rosacea patients through serum fetuin-A and carotid intima media thickness

BACKGROUND

The link between rosacea and various systemic conditions has been growing in prominence, even though the relationship between rosacea and cardiovascular disease remains a subject of debate in current research.

AIMS

Detecting the connection between rosacea and subclinical atherosclerosis using laboratory and ultrasonographic parameters.

METHODS

Fifty rosacea patients and 49 control were included in the study. Demographic, clinical, and laboratory data, including serum high sensitivity C-reactive protein (hs-CRP), fetuin-A (FA), and matrix gla protein levels were assessed. Carotid intima-media thickness (CIMT) was measured by carotid ultrasonography.

RESULTS

Serum hs-CRP levels (p = 0.009) and mean CIMT (p = 0.001) were significantly higher, while serum FA levels were significantly lower (p < 0.001) in the rosacea patients compared with control. The number of patients with mean CIMT>75th percentile according to age and sex were significantly higher in the rosacea group (p = 0.001). Rosacea patients with ocular involvement exhibited significantly higher hs-CRP values in comparison to those without ocular involvement (p = 0.008). No significant correlation was detected between disease duration, severity, subtype and the study parameters.

CONCLUSIONS

This study results suggest that rosacea poses an independent risk for subclinical atherosclerosis regardless of its severity, duration, or subtype. Therefore, individuals diagnosed with rosacea should receive careful evaluation and monitoring to detect possible cardiovascular complications promptly. Furthermore, our study hints at a potential elevated risk of subclinical inflammation in rosacea patients with ocular involvement, warranting additional attention and further investigation.

Lipid Alterations and Metabolism Disturbances in Selected Inflammatory Skin Diseases

Lipidomics is a term used to define the field that analyzes the structure, functions, and interactions of lipids. Inflammatory dermatoses and lipid disturbances are interrelated, especially due to chronic inflammatory conditions. This review discusses lipidomics in selected inflammatory skin diseases: psoriasis, lichen planus, and atopic dermatitis, as well as the less commonly mentioned hidradenitis suppurativa, rosacea, and acne vulgaris. Lipid homeostasis disorders are common; they are especially well-documented in psoriasis, lichen planus, and atopic dermatitis. Future studies are required for better insight into this issue, particularly on the skin lipidome. Understanding lipidomics, in particular skin diseases, increases our knowledge about their pathogenesis, and may become useful in adjusting tailored management for each patient as well establishing prognosis. Noteworthily, it seems advisable to alert doctors to the need to analyze lipid parameters and the complications of abnormal lipid metabolism in dermatological patients, which could decrease their comorbidities and improve the life quality and health condition of dermatological patients.

Evaluation of subclinical atherosclerosis in rosacea patients by flow-mediated dilatation method

BACKGROUND

Rosacea may contribute to the development of cardiovascular (CV) diseases by causing endothelial dysfunction (ED), which is known to be the initial step of atherosclerosis, due to its inflammatory features.

OBJECTIVE

This study aimed to assess ED in rosacea patients using the flow-mediated dilatation (=dilation) (FMD) method.

METHODS

Seventy-three rosacea patients and 73 age, gender-matched healthy volunteers were enrolled. Individuals with cardiac risk factors, pregnant, and lactating women were excluded. Demographic, clinical data and anthropometric measurements were recorded. FMD measurement was performed ultrasonographically by a cardiologist. Systolic and diastolic blood pressures (BP) were measured and hemogram, erythrocyte sedimentation rate (ESR), C-Reactive Protein (CRP), total cholesterol, triglyceride, low-density lipoprotein (LDL), high-density lipoprotein (HDL), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), and fasting blood glucose values were assessed.

RESULTS

The FMD value was statistically lower in rosacea patients compared with healthy controls (p = 0.000). Metabolic syndrome, systolic and diastolic BPs, and plasma NLR were higher in the rosacea group (p = 0.009, p = 0.000, p = 0.000, p = 0.000, respectively). According to the multivariate linear regression analysis, rosacea type significantly predicted FMD.

CONCLUSIONS

Rosacea is not only a disease limited to the skin, but it may also have systemic involvement. A significant difference was found between FMD values measured in between the case and control groups, suggesting rosacea may have an atherogenic effect. Possible cardiac risks should be considered in rosacea patients, and further evaluation could be warranted.

Rosacea, not just skin deep: Understanding thesystemic disease burden

Rosacea is a common inflammatory skin condition with four main clinical subtypes: erythematotelangiectatic, papulopustular, rhinophymatous, and ocular. Although several genetic and environmental factors have been linked with triggering rosacea, the pathogenesis still remains poorly understood. There is an increasing evidence in the literature to support that rosacea is a harbinger of several systemic comorbidities and may represent a chronic, systemic, inflammatory state. We have provided the most up-to-date evidence on the association between rosacea and several systemic diseases, discussing that rosacea is not just a skin disorder but a systemic disease process.

Relationship between rosacea and chronic obstructive pulmonary disease: Rosacea and comorbidities

BACKGROUND

Rosacea is a chronic inflammatory skin disease that has been reported to be associated with many systemic disorders including respiratory diseases.

AIMS

This study aims to investigate respiratory function in patients with rosacea.

PATIENTS/METHODS

Patients with rosacea and age- and gender-matched healthy volunteers were included in this cross-sectional study. Spirometric pulmonary function tests including the percentage of forced vital capacity (FVC%), percentage of forced expiratory volume in one second (FEV 1%), forced expiratory flow at 25-75% of FVC (FEF 25-75%), and FEV 1/FVC ratio was assessed in both patient and controls. The potential relationship between rosacea severity and pulmonary functions was assessed.

RESULTS

A total of 120 patients with rosacea and 120 healthy controls were enrolled in the study. Compared to the controls, FEV 1%, FEV 1/FVC%, and FEF 25-75% values were significantly lower in patients with rosacea. Lower FEV 1/FVC% values were found to be associated with disease severity. FEV 1%, FEV 1/FVC%, and FEF 25-75% values were found to be more useful in differentiating the patients from healthy subjects.

CONCLUSIONS

This study showed that patients with rosacea may have abnormal respiratory function compared to healthy subjects. Besides, disease severity was associated with worse respiratory functions. We believe that patients with rosacea, particularly those with additional risk factors, should be screened for respiratory disorders.

Assessment of thyroid disorders in patients with rosacea: a large case-control study

Background

The frequency of autoimmune diseases and thyroid cancer has been increasingly reported in association with rosacea. However, studies investigating thyroid diseases in rosacea are scarce with conflicting results.

Objective

To investigate the relationship between thyroid disorders and rosacea.

Methods

A large case-control study on age- and gender-matched 2091 rosacea patients and 9572 controls was conducted. Rosacea patients using the rosacea-specific ICD codes were compiled from the hospital records. Additionally, all participants were evaluated in terms of the presence of hypothyroidism and hyperthyroidism. Conditional logistic regression analysis was used to compute case-control odds ratios (OR) with 95% confidence intervals.

Results

The analysis comprehended 2091 rosacea patients (1546 female, 545 male; mean 48.73 ± 14.53 years) and 9572 controls (7009 female, 2563 male; mean 48.73 ± 15.1 years). Whereas the rate of hypothyroidism was significantly higher in rosacea patients (OR = 1.3, 95% CI 1.13–1.49, p < 0.001), there was no significant difference in the rate of hyperthyroidism between the groups (OR = 1.12, 95% CI 0.81–1.53, p = 0.497). Stratification for gender revealed a significant association between hypothyroidism and rosacea in females (OR = 1.27, 95% CI 1.1–1.47, p = 0.002) and males (OR = 1.58, 95% CI 1.04–2.4, p = 0.032). The frequency of hypothyroidism in rosacea patients increased towards the age range of 40–49 and then decreased, parallel with the hypothyroidism frequency of the study population.

Study limitations

Different subtypes and severities of rosacea were not distinguished.

Conclusions

Hypothyroidism may be a comorbidity of rosacea and investigation for hypothyroidism may be appropriate when evaluating rosacea patients.

Evaluation of epicardial fat thickness and the ankle-brachial index in patients with rosacea: A case-control study

BACKGROUND

Recent data suggest that rosacea is related to cardiovascular diseases (CVD) due to its inflammatory nature and immune dysregulation.

AIM

The aim of this study was to evaluate the values of epicardial fat thickness (EFT) and the ankle-brachial index (ABI) in patients with rosacea, as indicators of subclinical atherosclerosis and CVD risk.

METHODS

This prospective case-control study was carried out on 62 participants, including 31 rosacea patients and 31 controls. The values of EFT and ABI were measured in all subjects.

RESULTS

The mean thickness of EFT was statistically higher in rosacea patients (0.54 ± 0.12 mm) than in the controls (0.39 ± 0.05 mm) (P < 0.01). ABI was not significantly different between the subjects with rosacea and the comparison group (1.02 ± 0.1 vs 0.98 ± 0.07; P = 0.131). A total of 29% of the rosacea patients had mitral valve insufficiency (MVI), while 3.2% of the control group had MVI (P = 0.006). A mild degree of tricuspid valve insufficiency (TVI) was present in 45.2% of the rosacea patients, while 19.4% of the controls had TVI (P = 0.03).

CONCLUSION

Rosacea may be associated with subclinical cardiac dysfunction. EFT measurements in rosacea patients can provide early detection of possible subclinical cardiovascular diseases, which can be life-extending in rosacea. However, further studies with larger sample sizes are required to confirm the present findings.

Carotid intima-media thickness and serum proinflammatory cytokine levels in rosacea patients without cardiovascular risk factors

There is a growing body of evidence linking rosacea to various systemic disorders, even though data regarding the association between rosacea and cardiovascular diseases are presently controversial. We sought to investigate the potential association of rosacea with subclinical atherosclerosis and serum proinflammatory/proatherogenic markers. This study included 44 patients with rosacea and 44 age-matched and sex-matched healthy control subjects. Patients with traditional cardiovascular risk factors or a history of cardiovascular events were excluded. Demographic, clinical, and laboratory data, including serum interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and high-sensitivity C-reactive protein (hs-CRP) levels were assessed. Carotid intima-media thickness (CIMT) and carotid plaques were measured by carotid ultrasonography. Serum IL-1β (P < .001), IL-6 (P < .001), TNF-α (P < .001), and hs-CRP (P < .001) levels were significantly higher in the patient group compared with the control group. Mean CIMT values did not differ significantly between the patient group and control group (P > .05). Patients with moderate to severe rosacea had a significantly greater CIMT than those with mild rosacea (P = .047). Rosacea patients with eye involvement had a significantly greater CIMT than those without eye involvement (P = .008). There was no significant correlation between CIMT values and inflammation parameters. As conclusion, in the absence of other traditional cardiovascular risk factors, rosacea does not seem to affect mean CIMT value. However, specific subgroups such as patients with moderate to severe disease or with eye involvement are associated with increased subclinical atherosclerosis and may require additional attention for cardiovascular disease prevention.

Association between rosacea and cardiovascular disease: A systematic review and meta-analysis

BACKGROUND

Rosacea and cardiovascular diseases (CVD) are chronic inflammatory disorders. While CVD is the leading cause of mortality globally, increasing evidence indicates that CVD prevalence could be higher among patients with rosacea.

AIMS

This review aimed to determine the association between the prevalence of CVD and rosacea.

PATIENTS/METHODS

A systematic review of observational studies with controls available in MEDLINE, EMBASE, PubMed, Cochrane, and Web of Science databases was conducted. We performed a pooled meta-analysis using random-effects weighting. Overall, 11 studies met the inclusion criteria, which indicated increased odds for at least one risk factor of CVD, including diabetes, high blood pressure, or dyslipidemia.

RESULTS

The pooled meta-analysis indicated an association of rosacea with higher odds of insulin resistance or diabetes (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.97-1.45), high systolic blood pressure (OR, 1.96; 95% CI, 1.35-2.84), dyslipidemia (OR, 1.50; 95% CI, 1.19-1.88), and CVD (OR, 6.65; 95% CI, 2.80-15.76). No publication bias was detected. The effect of confounding factors due to overlapping symptoms and lack of individual-level data were limitations of this review.

CONCLUSION

Patients with rosacea have a high risk of CVD. However, further studies are warranted to confirm the association between rosacea and CVD.

Is rosacea a systemic disease?

Rosacea is a chronic inflammatory facial disease occurring world-wide. The incidence of rosacea is increasing with age, with the clinical course being characterized by relapses. The pathogenesis of rosacea is not completely understood, but neurovascular and immunologic mechanisms are involved. Rosacea has a number of known extrinsic triggers that should be avoided, such as sun exposure, heat and cold, alcoholic beverages, and spicy food. Of greater importance is the observation that rosacea may develop as a manifestation of systemic diseases with a significant morbidity and even mortality. Obesity, Helicobacter pylori infection, smoking, and inflammatory bowel disease bear a significant risk for the development of rosacea. Metabolic, psychiatric, and neurologic disorders and certain types of cancer show a significant association with rosacea. The possible link to cardiovascular events is debatable. There are extrafacial and extracutaneous manifestations of rosacea, such as the red scalp syndrome, ocular rosacea, and migraine. Rosacea should be considered a systemic disease.

Noninvasive assessment of subclinical atherosclerosis in patients with rosacea

BACKGROUND

Rosacea is a chronic, inflammatory cutaneous disorder that is characterized by remissions and relapses that commonly occur in patients over the age of 30 years. There have been many studies in literature evaluating the relationship between cardiovascular disease and psoriasis, which is a chronic inflammatory disease; however, there have been very few studies to date evaluating the relationship between rosacea and cardiovascular disease risk.

METHODS

The study included 52 consecutive rosacea patients and 52 healthy controls matched for age, gender and Body Mass Index. Demographic data, anthropometric measurements, lipid parameters, C-reactive protein (CRP), epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) were recorded.

RESULTS

The main finding of the present study is the significantly higher EFT (P˂0.001) and CIMT (P˂0.001) values identified in patients with rosacea than in the control group and CRP (P=0.004), total cholesterol (P=0.003) and low-density lipoprotein (P=0.004) levels were also significantly higher in the rosacea group. EFT was significantly correlated with CIMT in the rosacea group (P=0.041). Total cholesterol (OR=1.032, P=0.017), CIMT (OR=7.391, P˂0.001) and EFT (OR=3.959, P=0.036) were independently associated with rosacea.

CONCLUSIONS

Clinicians should be aware of the risk of cardiovascular disease when presenting with conditions involving persistent subclinical inflammation, as in the case of rosacea. EFT and CIMT measurements, which are noninvasive, easily accessible and cheap, can be useful to determine cardiovascular risk in rosacea patients.

The investigation of the relationships of demodex density with inflammatory response and oxidative stress in rosacea

The relationships of demodex density with systemic oxidative stress, inflammatory response, and clinical severity in rosacea are not clear. This study aimed to (a) analyze the levels of systemic oxidative stress, antioxidant capacity, inflammatory parameters, and matrix metalloproteinases (MMPs) in systemic circulation in patients with rosacea, (b) identify the relationship between mite density and both oxidative stress and inflammation, and (c) investigate the role of photoaging and sebum secretion in etiopathogenesis. Forty patients with rosacea and 40 age-, sex-, and skin phenotype-matched healthy volunteers were included in the study. Clinical disease severity of the patients was determined. Sebum levels were measured in both the groups, and photoaging was evaluated. Reflectance confocal microscopy was used to calculate demodex density. Serum total antioxidant capacity (TAC), total oxidant capacity (TOC), myeloperoxidase (MPO), MMP-1, MMP-9, arylesterase (ARES), interleukin-1β (IL-1β), paraoxonase-1 (PON-1), and tumor necrosis factor-α (TNF-α) levels were also analyzed. The patients with rosacea had significantly higher serum TOC and lower TAC levels (p < 0.001). The serum ARES and PON-1 levels were significantly lower (p = 0.045 and p < 0.001, respectively); however, the serum levels of MMP-1, MMP-9, IL-1β and MPO were higher in the patient group. Demodex parameters were higher in the patient group compared to the control group. There was no significant correlation between the number of mites and disease severity. In addition, the number of mites was not correlated with the serum levels of TAC, TOC, OSI, MPO, MMP-1, MMP-9, ARES, PON-1, TNF-α, and IL-1β. However, sebum levels were directly proportional to the number of mites. Photoaging severity was similar between the patients and control subjects. The changing sebaceous microenvironment in rosacea leads to an increase in the number of demodex mites. However, increased demodex density does not alter disease severity, level of oxidative stress, or inflammation. Although none of the patients with rosacea had any underlying systemic disease, patients' systemic oxidative stress and inflammation parameters were found high in systemic circulation. It is assumed that the patients with rosacea are more prone to systemic diseases.
