“…Mean plasma homocysteine levels were significantly higher than sex and age matched controls. 29 While Cakmak et al 30 did not observe significant differences in homocysteine, they found that homocysteine levels correlated with Psoriasis Areas and Severity Index (PASI) in the psoriasis group. It is important to note that homocysteine may be a surrogate marker of CVD rather than an etiologic factor, as recent studies of pharmacotherapy to lower homocysteine levels have not impacted vascular outcomes.…”

The daily intake of FA of 5% Americans age 50 and over and in one study of psoriatic American women is about 1 mg. A patient with plaque psoriasis on 10 mg lisinopril did not improve on vitamins B12 and B6 alone. When folic acid 5 mg daily was added PASI improved 50%. Three cases of plaque psoriasis flared when given 1-2 mg folic acid (FA), 100 mg vitamin B6 and 1000 mcg daily B12. When daily FA was increased to 4 to 7 mg daily all three cases improved their disease.

“…After the studies made in 1990s where high levels of homocysteine were found in plasma samples of subjects who had or would likely to have a history of myocardial infarction, ischemic stroke or peripheral vascular disease and the association of homocysteine with atherosclerosis and hypercoagulability had been shown [6][7][8][9][10][11][12] , along with increased attention to the comorbidities of psoriasis, as far as we know, 19 studies have been conducted to explore homocysteine levels in these patients. Homocysteine level was found to be high in 12 and normal in 7 of these studies [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] . Since this sulfur-containing amino acid is not taken through diet and not producing protein, homocysteine is formed via methionine catabolism 8,11,27 .…”

ÖzBackground and Design: Homocysteine, a sulfur-containing amino acid, is known to be related with autoimmunity-inflammation, cardiovascular disease and DNA methylation. In this case-control study, we aimed to determine plasma homocysteine, folic acid, vitamin B12 and vitamin B6 levels in patients with psoriasis. Materials and Methods: Smoking, alcohol and coffee consumption habits were recorded in adult patients with plaque-type psoriasis and age-and sex-matched controls. Height and weight measurements were performed and Psoriasis Area and Severity Index (PASI) scores were calculated. Fasting venous blood samples were collected to determine homocysteine, folic acid, vitamin B12, vitamin B6, glucose, total cholesterol, triglyceride, high density lipoprotein (HDL), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels. Results: There was no significant difference between psoriasis patients (n=43) and controls (n=47) in body mass index and alcohol and coffee consumption. Smoking rate was significantly high in psoriasis patients. The median PASI score was 10.0 (8.3-12.8). Plasma homocysteine, folic acid, vitamin B12, vitamin B6, total cholesterol, triglyseride, ESR and CRP values were not significantly different between patients and the controls. HDL level was low in psoriasis patients (p=0.001). Plasma homocysteine level was higher in males than in females. There was no relationship of homocysteine levels with patient's age, PASI scores, ESR, CRP values and lipids. Homocysteine levels were inversely related with folic acid and vitamin B12 (p=0.000, r=-0.436, p=0.047, r=-0.204, respectively). We did not find any relationship between homocysteine and vitamin B6 levels. Conclusion: There was no increase in plasma homocysteine levels in psoriasis patients we followed up. Homocysteine level increases in inflammatory disorders and this increase is accepted as a cardiovascular disease marker. Homocysteine homeostasis may be balanced in our patients because of the genetic background and/or nutritional habits in this population Keywords: Psoriasis, homocysteine, folic acid Amaç: Homosistein kardiyovasküler hastalık, otoimmünite-enflamasyon ve DNA metilasyonu ile ilişkilendirilen sülfür içeren bir aminoasittir. Bu olgu-kontrol çalışmasında psoriazisli hastalarda plazma homosistein düzeylerinin ve homosisteini etkileyen folik asit, vitamin B6 ve vitamin B12 düzeylerinin belirlenmesi amaçlanmıştır. Gereç ve Yöntem: Polikliniğimizde takip edilen erişkin plak tip psoriazis hastaları ile yaş ve cinsiyet uyumlu kontrol grubunda alkol, kahve ve sigara tüketimi sorgulandı, katılımcıların boy ve ağırlıkları ölçüldü. Hastaların Psoriazis Alan Şiddet İndeksleri (PAŞİ) hesaplandı.

Homocysteine, vitamin B₁₂ and folic acid levels in psoriasis patients

Abstract: Homocysteine levels correlated with psoriasis area and severity index in the patient group, which shows the disease severity. The increase in cardiovascular mortality with the severity of psoriasis might be also due to the effects of homocysteine.
