好健康熱頭條 ─ 吸菸惡化牛皮癬
癮君子讓自己「皮膚」處於險境！最新研究顯示，每天抽超過半包菸的人，罹患嚴重牛皮癬的機率是每天抽10支（或少於）者的兩倍。
研究團隊表示，實驗結果指出，吸菸會惡化牛皮癬，並強調有皮膚問題的人應戒菸；吸菸同時也是其他疾病的危險因子，像是肺癌和心臟病，而其與牛皮癬間的關聯卻鮮為人知。
牛皮癬是一種慢性皮膚病，它不具傳染性也不會致命，但它會造成搔癢感，有時皮膚上會出現令人尷尬的紅色鱗斑，而且牛皮癬會擴散到指甲和關節。
【吸菸影響皮膚】
在發表於《皮膚科檔案》的研究報告中，研究團隊觀察818名罹患牛皮癬的人，比對其吸菸史和牛皮癬的嚴重程度。
研究結果顯示，相較於輕度菸癮者，重度菸癮者牛皮癬的嚴重程度高出兩倍；此外，菸齡愈長（同時評估吸菸量和吸菸期程）也會提高嚴重牛皮癬的風險。
研究團隊發現，菸齡對牛皮癬嚴重程度的影響，在女性身上比男性明顯，這代表著目前的女性吸菸者以及剛戒菸的人，牛皮癬的嚴重程度較高（72%）。
紐約西奈山醫學中心Mark G. Lebwohl醫師於伴隨研究發表的評論中表示，實驗顯示研究團隊對牛皮癬仍有許多未作說明的部份；舉例來說，實驗結論並未解答到底是牛皮癬導致吸菸，還是吸菸惡化了牛皮癬，其間的因果關係尚未知。
Smoking May Make Psoriasis Worse
Heavy smokers may be putting their skin at risk.
A new study shows people who smoked more than a pack of cigarettes per day were twice as likely to have severe psoriasis as those who smoked 10 cigarettes or less per day.
Researchers say the results suggest that cigarette smoking may exacerbate existing psoriasis, and highlights the need for people with the skin condition to quit smoking. Smoking is a risk factor for many other diseases, such as lung cancer and heart disease, but little is known about its relationship to psoriasis.
Psoriasis is a chronic skin disease that is not contagious or life-threatening, but it causes itchy and sometimes embarrassing red, scaly patches on the skin. Psoriasis can also affect the nails and joints.
Smoking May Affect Skin
In the study, published in the Archives of Dermatology, researchers compared smoking history and severity of psoriasis in 818 adults with psoriasis.
The results showed that people who smoked heavily had twice the risk of severe psoriasis compared with light smokers.
In addition, an increasing number of cigarette-years (a measurement of both the intensity and duration of smoking) also raised the risk of severe psoriasis.
Researchers found that the effect of cigarette-years on psoriasis severity was stronger for women than for men. This means that present women smokers and recent quitters had a higher risk (72%) for worse psoriasis.
In an editorial that accompanies the study, Mark G. Lebwohl, MD, of Mount Sinai Medical Center in New York, says the study shows researchers still have a lot to learn about psoriasis. For example, the study does not answer whether psoriasis leads to smoking or smoking exacerbates psoriasis.
