Increased frequency of pulmonary hypertension in psoriasis patients

Concomitant Interstitial Lung Disease with Psoriasis

Background

We encounter interstitial lung disease (ILD) patients with psoriasis. The aim of this case series was to examine clinical and radiographic characteristics of patients with concomitant psoriasis and ILD.

Methods

This is a retrospective review of our institutional experience of ILD concomitant with psoriasis, from the database in the Advanced Lung/Interstitial Lung Disease Program at the Mount Sinai Hospital. Out of 447 ILD patients, we identified 21 (4.7%) with antecedent or concomitant diagnosis of psoriasis. Clinical, radiographic, pathological, and outcome data were abstracted from our medical records.

Results

Median age was 66 years (range, 46-86) and 14 (66.7%) were male. Thirteen (61.9%) had not previously or concomitantly been exposed to immunosuppressive therapy directed against psoriasis. Two (9.5%) ultimately died. Clinical diagnosis of ILD included idiopathic pulmonary fibrosis, 11 (52.4%); nonspecific interstitial pneumonia (NSIP), 2 (9.5%); cryptogenic organizing pneumonia, 2 (9.5%); chronic hypersensitivity pneumonitis, 2 (9.5%); and the others, while radiographic diagnosis included usual interstitial pneumonia pattern, 9 (42.9%); NSIP pattern, 6 (28.6%); organizing pneumonia pattern, 4 (19.0%); hypersensitivity pneumonitis pattern, 2 (9.5%); and the others.

Conclusions

We report 21 ILD cases with antecedent or concomitant diagnosis of psoriasis. Further prospective studies are required to determine the association between ILD and psoriasis.

Incidence of Pulmonary Arterial Hypertension in Patients with Psoriasis: A Retrospective Cohort Study

CONTEXT

Inflammatory signaling may play an important role in the pathogenesis of pulmonary arterial hypertension (PAH).

OBJECTIVE

To assess the incidence of PAH in patients with mild and severe psoriasis compared with their respective controls.

DESIGN

From January 2004 to November 2012, we performed a retrospective cohort study of patients with psoriasis in the Kaiser Permanente Southern California Health Plan. Patients with an International Classification of Diseases, Ninth Revision Clinical Modification diagnostic code for psoriasis (696.1) or psoriatic arthritis (696.0) without a prior diagnosis of primary PAH (416.0) or secondary PAH (416.8) were eligible for inclusion. Patients who had never received a diagnosis of psoriasis were frequency-matched by age, sex, and race to form the control cohorts.

MAIN OUTCOME MEASURES

Incidence of PAH in patients with psoriasis compared with matched controls.

RESULTS

There were 10,115 patients with mild psoriasis, 3821 with severe psoriasis, and 69,360 matched controls. On multivariable analysis, there was a significantly increased risk of PAH developing in the severe psoriasis cohort vs their controls (hazard ratio = 1.46, 95% confidence interval = 1.09-1.94).

CONCLUSION

The systemic inflammatory process underlying psoriasis may be a cause for an increased risk of PAH, but there are numerous secondary causes of PAH, some of which were not accounted for in our study. Further prospective, randomized controlled trials are necessary to establish psoriasis as a risk factor for PAH.

Influence of psoriasis on circulatory system function assessed in echocardiography

Psoriasis vulgaris is a chronic disease with a multifactorial pathogenesis. It affects about 2–4 % of the population all over the world. In course of psoriatic arthritis, joints’ damages are observed. In patients with psoriasis vulgaris and psoriatic arthritis, there is increased morbidity and mortality caused by cardiovascular diseases observed. The aim of the study is to analyze the echocardiography of patients with psoriasis vulgaris and psoriatic arthritis on the basis of the literature available in PubMed database. Abnormalities found in echocardiography of patients with psoriasis include valvular defects (40.7 % of the patients), left ventricle diastolic dysfunction (27.8 %), and left ventricle hypertrophy (11.1 %). Left ventricle’s systolic disorders, increased aorta stiffness index and increased pulmonary artery blood pressure were also observed in this group of patients.

Psoriasis and risk of heart failure: a nationwide cohort study

AIMS

Psoriasis is a common inflammatory disease that is associated with increased risk of cardiovascular disease, including myocardial infarction. Heart failure (HF) is independently associated with several cardiovascular risk factors and is a major cause of cardiovascular morbidity and mortality. The association between psoriasis and HF is unclear and we therefore investigated the risk of new-onset HF in a nationwide cohort of psoriasis patients compared with the background population.

METHODS

The study included the entire Danish population aged ≥18 years followed from 1 January 1997 until HF, death or 31 December 2011. Information on comorbidity and concomitant medication was identified by individual-level linkage of administrative registers. New-onset HF was defined as first hospital admission for HF. Incidence rates of new-onset HF were calculated and adjusted hazard ratios were estimated by multivariable Cox regression models adjusted for age, gender, comorbidity and cardiovascular medications.

RESULTS

A total of 5 485 856 subjects were eligible for analysis. In the study period 66 389 patients with new-onset psoriasis, including 11 242 patients with severe psoriasis, were identified. The overall incidence rates of new-onset HF were 2.82, 4.22 and 4.70 per 1000 person-years for the reference population, mild psoriasis and severe psoriasis, respectively. Compared with the reference population, the fully adjusted hazard ratios for new-onset HF were increased in patients with psoriasis with a hazard ratio 1.22 (95% confidence interval 1.16-1.29) and hazard ratio of 1.53 (95% confidence interval 1.34-1.74) for those with mild and severe disease, respectively.

CONCLUSION

In this nationwide cohort, psoriasis was associated with a disease severity-dependent increased risk of new-onset HF.

High prevalence of cardiovascular risk factors in patients with moderate or severe psoriasis in northern China

Recent studies suggest that psoriasis is a systemic disorder associated with cardiovascular disease (CVD) risk factors, such as obesity, hypertension and dyslipidemia. However, these risk factors have not been widely recognized across different populations. This cross-sectional study aimed to examine the association of risk factors for CVD with psoriasis by comparing patients with psoriasis and matched controls in northern China. This study identified 291 patients with diagnosed moderate or severe psoriasis as cases and 445 age- and gender-matched subjects as controls. A significant association (P < 0.01) was observed between overall psoriasis incidence and smoking [odds ratio (OR), 2.96; 95 % confidence interval (CI) 2.09-4.09], alcohol consumption (OR, 3.77; 95 % CI 2.381-5.955), diabetes (OR, 2.79; 95 % CI 1.70-4.59), hypertension (OR, 2.19; 95 % CI 1.56-3.06) and hyperlipidemia (OR, 1.76; 95 % CI 1.29-2.40). Furthermore, hypertension correlated with the duration of psoriasis after adjustment for age and sex. Hyperlipidemia, smoking and alcohol consumption were related to the severity of the disease. Moreover, patients with psoriasis had lower levels of apolipoprotein B (ApoB) and lipoprotein (Lip) than did controls (P < 0.05). These data suggest that multiple risk factors for CVD are associated with psoriasis. CVD risk factor screening should be performed, and appropriate measures should be taken accordingly for psoriasis patients.

Psoriasis and cardiovascular disease

Current epidemiological data support the association between psoriasis and cardiovascular (CV) risk, in apparent correlation with psoriasis severity. Although less unanimously, evidence of an increased prevalence of CV diseases among psoriasis patients has been reported, including ischemic heart disease, cerebrovascular, peripheral vascular and heart structural disorders. In particular, various studies showed a correlation between psoriasis and major CV events (i.e., myocardial infarction, stroke), while others investigated subclinical changes of blood vessels, such as intima-media thickness increase, arterial stiffness and coronary artery calcification. A series of different mechanisms, like traditional CV risk or iatrogenic risk factors, inflammation, hemostasis dysregulation, hyperhomocysteinemia, and shared genetic susceptibility, are thought to underlie this epidemiological association. Among these elements, inflammation and its related cytokine milieu, including Th1-mediated response and Th17/Treg imbalance, C reactive protein and the newly implicated osteopontin are considered to play a primary role, even if yet to be fully understood.

Lipid disturbances in psoriasis: an update

Psoriasis is a common disease with the population prevalence ranging from 2% to 3%. Its prevalence in the population is affected by genetic, environmental, viral, infectious, immunological, biochemical, endocrinological, and psychological factors, as well as alcohol and drug abuse. In the recent years, psoriasis has been recognised as a systemic disease associated with numerous multiorgan abnormalities and complications. Dyslipidemia is one of comorbidities in psoriatic patients. Lipid metabolism studies in psoriasis have been started at the beginning of the 20th century and are concentrated on skin surface lipids, stratum corneum lipids and epidermal phospholipids, serum lipids, dermal low-density lipoproteins in the psoriatic skin, lipid metabolism, oxidative stress and correlations between inflammatory parameters, lipid parameters and clinical symptoms of the disease. On the basis of the literature data, psoriasis can be described as an immunometabolic disease.

Serum lipid profile paraoxonase and arylesterase activities in psoriasis

Psoriasis is a common chronic and recurrent inflammatory skin disease with unknown etiology that has been associated with abnormal plasma lipid metabolism and oxidative stress. There are controversial results in the previous studies investigating oxidant/antioxidant systems in psoriasis.The aim of this work was to evaluate dyslipidemia, oxidative stress, total antioxidant capacity and serum paraoxonase (PON1) and arylesterase (ARE) activities in psoriasis, and to look for a correlation between these parameters and lesion percentage in psoriasis.Thirty psoriatic patients and twenty three sex- and agematched healthy volunteers were included in the study. From blood samples, lipid profile, malondialdehyde (MDA) levels, total antioxidant capacity (TAO), serum PON1 and ARE activities were determined.No significant differences between the patients and controls were found in terms of total cholesterol, triacylglycerol (TAG), HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, MDA and TAO levels. Serum PON1 and sodium-stimulated PON1 activities (p < 0.05) and ARE activity (p < 0.01) were found significantly higher in the patients than in the controls. There was not any significant correlation between lesion percentage and the parameters studied.
