Increased serum level of N-terminal Pro-B-type natriuretic peptide as a possible biomarker of cardiovascular risk in psoriatic patients.

BACKGROUND: Apparently, these days psoriasis is regarded as a systemic disease with frequent cardiovascular comorbidities, such as hypertension, myocardial infarction, valvular defects etc., which may lead to reduced lifespan or even sudden death. Therefore, it is important that biomarkers helpful in early detection or prediction of cardiovascular complications as well as their prevention should be identified. Even though the N-terminal pro B-type natriuretic peptide (NT-proBNP) is a well-known cardiovascular predictor in cardiovascular (CV) patients and in the general population, its usefulness in detection of CV comorbidities in psoriatic patients is still unclear. OBJECTIVE: The aim of the study was to determine whether the N-terminal pro B-type natriuretic peptide (NT-proBNP) concentration was increased in psoriatic patients. METHODS: The study included 73 psoriatic patients and 45 age-matched healthy individuals. The serum NT pro-BNP concentration as well as lipid profile parameters were assessed in the study and control groups. Correlations between patients' clinical data, their serum NT-proBNP and lipid concentrations were calculated. RESULTS: The serum concentration of NT-proBNP was significantly higher in psoriatic patients (109.22 ± 172.59 pg/mL) in comparison with controls (35.82 ± 22.90 pg/mL) (P = 0.000054). In 28 (38.36%) psoriatic patients the lipid profile was within normal limits, whereas in 45 (61.64%) psoriatic patients triglyceride and/or total cholesterol were increased. Moreover, in both psoriatic groups, i.e. normo- and hyperlipidaemic, NT-proBNP concentrations were significantly higher compared to normo- and hyperlipidaemic controls, P = 0.02 and P = 0.001 respectively. A positive correlation was found between the NT-proBNP concentration and duration of psoriasis (P < 0.05). CONCLUSIONS: The study findings confirmed higher NT-proBNP concentrations in psoriatic patients, which could be a useful biomarker of CV disease in both normo- and hyperlipidaemic groups.

Cardiovascular disease in psoriatic post-menopausal women.

BACKGROUND: It is generally accepted that the risk of cardiovascular disease (CVD) in women is significantly increased after the menopause. Hormonal changes associated with the menopausal transition may also alter the course of autoimmune diseases. It has been reported that menopause may exacerbate the symptoms of rheumatoid arthritis, systemic sclerosis and giant cell arteritis, but attenuate the course of systemic lupus erythemathosus. There is a growing body of literature indicating that the course of psoriasis may be altered by menopausal hormone changes. Considering the fact that both psoriasis and menopause are independent risk factors for CVD, and that menopause may exacerbate the course of psoriasis, a possible additive effect between these two conditions may be crucial for proper monitoring and treatment of peri- and post-menopausal psoriatic patients. OBJECTIVE: The aim of this study is to analyse potential relationship between psoriasis, menopausal status and risk of CVD. MATERIALS AND METHODS: A retrospective analysis of the Clalit Health Services database was performed in an attempt to provide new data and the available literature concerning these issues was reviewed. Data on cardiovascular events in 10 872 female psoriatic patients and 19 471 controls were extracted and compared. RESULTS: In both psoriatic and control patients the association of CVD increased with age. The association of CVD was significantly greater in psoriatic patients, but no significant differences were found between any of age groups. CONCLUSIONS: The association of psoriasis and CVD in women increases with age but there is insufficient evidence to confirm that menopause increases the risk of psoriasis. Further studies directly addressing this issue are needed.

Skin lesions in a 16-month-old toddler with impaired zinc absorption.

Acrodermatitis enteropathica is a rare, autosomal recessive condition which results from impaired zinc absorption in the gastrointestinal tract. We report a 16-month-old female patient with a 7-month history of periorificial and acral skin lesions. Diagnosing of Acrodermatitis enteropathica was established on the basis of the patient's history as well as clinical and laboratory findings (a lowered zinc level in the child's serum: 17.2µg/dL (N 70-160 µg/dL)). Rapid clinical improvement was observed right after launching zinc supplementation.
