68例白癜风患者血清β2—微球蛋白与免疫球蛋白水平的检测

测定６８例白癜风患者血清β２－微球蛋白（β２－Ｍ）与免疫球蛋白ＩｇＧ、ＩｇＡ、ＩｇＭ水平。测定结果，寻常型进展期与稳定期白癜风血清β２－Ｍ水平均显著性升高，以进展期尤甚（Ｐ＜０．０１），节段型白癜风血清β２－Ｍ水平无显著性改变（Ｐ＞０．０５）；寻常型白癜风血清免疫球蛋白ＩｇＧ、ＩｇＡ、ＩｇＭ均显著高于对照组（Ｐ＜０．０１），节段型白癜风除血清ＩｇＧ升高外（Ｐ＜０．０５），ＩｇＡ、ＩｇＭ无显著性变化（Ｐ＞０．０５）。提示β２－Ｍ与白癜风自身免疫发病学说之间有一定的关系。

银屑病皮损中免疫细胞组分的研究

采用免疫组化技术检测３例寻常性银屑病患者皮损中免疫细胞的组分。结果发现银屑病皮损真皮上层中单个核细胞、ＨＬＡ－ＤＲ＋（活化）细胞和ＣＤ－１５＋（巨噬）细胞数均比非皮损部位显著增加（Ｐ＜０．０３，Ｐ＜０．００３和Ｐ＜０．０４）。ＣＤ－４５ＲＯ＋／ＲＡ＋（Ｔ／Ｂ）细胞数变化不大。研究结果提示银屑病发病与皮肤组织中积聚的免疫活化细胞在局部产生一系列引起表皮细胞异常增殖与分化的细胞因子有关。

The lipid profile in psoriasis: a controlled study

BACKGROUND: Psoriasis is an inflammatory dermatosis that is characterized with hyperproliferation of keratinocytes and inflammatory infiltration in the epidermis and dermis. The high prevalence of atherosclerosis has been reported in psoriatic patients. High serum lipid level has been suggested in the pathogenesis of this phenomenon. In this study, our purpose was to compare the lipid profile in psoriatic patients with non-affected persons. METHODS: This study was designed and conducted as a case-control assay with 50 cases in the patient and control groups, respectively. The lipid profile, including serum level of triglyceride, cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were assessed in both groups. RESULTS: The patient and control groups each consisted of 50 cases (39 male and 11 female). The serum triglyceride, cholesterol, and LDL was significantly higher in psoriatic patients (P < 0.05) but not for HDL (P = 0.29). CONCLUSION: This study, like previous assays, shows that high serum lipid level is significantly more common in psoriasis. This fact may be responsible for higher prevalence of cardiovascular accident in psoriatic patients. It may be useful to do early screening and treatment of hyperlipidaemia in psoriasis to prevent the atherosclerosis and its complications.     

Lipoprotein (a) in patients with psoriasis: associations with lipid profiles and disease severity

Background  Lipoprotein (a) [Lp(a)] is a genetically determined molecule whose role has been implied in cardiovascular pathology, and whose levels have been reported to be elevated in patients with psoriasis.
Aim  To assess the serum levels of Lp(a) in patients with psoriasis, and to investigate the associations of Lp(a) with other lipids and with psoriasis severity.
Methods  Thirty-four patients with psoriasis and 26 healthy control subjects took part in the study. Serum levels of Lp(a) and total, high density lipoprotein (HDL), low density lipoprotein (LDL), and very low density lipoprotein (VLDL) cholesterol fractions were measured in all participants. The levels of triglycerides and total cholesterol were measured using enzymatic colorimetric tests; HDL and LDL cholesterol concentrations were determined by precipitation methods; the VLDL concentration was calculated according to the formula: VLDL cholesterol = triglycerides/5.
Results  Patients with psoriasis showed significantly higher serum levels of Lp(a) relative to controls. Even when controlling for normolipidemic vs. hyperlipidemic status, abnormal levels of Lp(a) (> 30 mg/dL) were observed significantly more often in patients than in controls. In both patients and controls, Lp(a) levels correlated positively with total and HDL cholesterol levels. In patients, Lp(a) levels correlated positively with psoriasis severity.
Conclusions  Lp(a) may be a factor contributing to an increased cardiovascular risk in patients with psoriasis. A pathogenetic link may exist between this lipoprotein and psoriatic pathophysiology.     

气质联用技术检测正常人与银屑病患者血清脂肪酸成分的差异

目的探讨正常人与银屑病患者的血清脂肪酸差异。方法采用气质联用(GC-MS)技术测定36例银屑病患者与22名正常对照组血清游离脂肪酸成分,利用主成分分析法与Logistic回归建立数学模型。结果银屑病患者主要脂肪酸成分棕榈酸甲酯和硬脂酸甲酯低于正常人(P<0.05),而其余主要成分脂肪酸与正常人差异无显著性(P>0.05)。采用Logistic回归方法将正常人与银屑病患者峰值建立模型,其W ald检验P<0.05。其中36例银屑病患者中35例被成功确认,符合率为97.2%。同样,正常人组22个样本中17例被成功确认,符合率为77.3%。结论银屑病患者存在游离脂肪酸代谢紊乱,其中棕榈酸甲酯和硬脂酸甲酯的变化可能与病情发展有关。     

Serum uric acid levels in untreated and PUVA-treated patients with psoriasis

Hyperuricemia occurs frequently in patients with psoriasis. An increased purin breakdown due to the enhanced epidermal turnover was stressed as a reasonable explanation. To prove this theory serum uric acid, cholesterol, triglyceride levels and the average body overweight were determined in 318 untreated psoriatic patients and the parameters were correlated with the extent of psoriatic skin involvement. In more than 100 psoriatic patients treated by oral photochemotherapy (PUVA), uric acid serum levels were examined additionally after the PUVA clearing phase and during PUVA maintenance treatment. The present study demonstrates: (1) There is no relationship between the frequency of hyperuricemia and the extent of psoriatic skin involvement, indicating that the increased epidermal turn over may not play a role in psoriatic hyperuricemia. (2) The most reasonable explanation for elevated uric acid in psoriasis seems to be a combination of genetic predisposition and hyperalimentation. (3) No significant change was found in the incidence of hyperuricemia under the influence of photochemotherapy.     

寻常型银屑病患者几种血清细胞因子的检测

Homocysteine, vitamin B12 and folic acid levels in psoriasis patients

Background  Hyperhomocysteinaemia is a risk factor for atherosclerotic cardiovascular disease, stroke, peripheral arterial occlusive disease and venous thrombosis. An association between psoriasis and cardiovascular diseases has been reported.
Aim  The aim of our study was to examine serum homocysteine, folic acid and vitamin B₁₂ levels in psoriasis patients.
Material and methods  We performed a cross-sectional study in 70 consecutive outpatients with chronic plaque psoriasis and 70 age- and gender-matched controls. Serum levels of homocysteine, vitamin B₁₂ and folic acid levels were measured in both groups.
Results  Serum homocysteine, folic acid and vitamin B₁₂ levels did not differ between patient and control groups. In psoriasis patients, homocysteine levels correlated directly with psoriasis severity as measured by psoriasis area and severity index. Serum homocysteine level inversely correlated with serum folic acid levels in the patient group.
Discussion  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.

Association of Adipokines,Insulin Resistance,Hypertension and Dyslipidemia in Patients with Psoriasis Vulgaris

BackgroundSystemic inflammation in psoriasis causes insulin resistance and cardiovascular diseases. Adipokines are adipose-tissue-derived factors that are involved in metabolic processes. It is thought that these adipokines are associated with the development of psoriasis.ObjectiveThe purpose of this study was to determine the changes in adipokine levels, insulin resistance, hypertension, and dyslipidemia over a 12-week period.MethodsThe study comprised 35 psoriasis patients and 50 controls. Blood samples were obtained twice from the patients, one sample at the start and one at the end of a 12-week follow-up period. The following parameters were assessed in both groups: serum fasting glucose, fasting insulin, homeostasis model assessment-estimated insulin resistance (HOMA-IR) index, serum lipids, adiponectin, leptin, resistin, chemerin, omentin, vaspin, visfatin, retinol-binding protein 4, and high-sensitivity C-reactive protein (hs-CRP) levels; blood pressure; body mass index; and the psoriasis area severity index (PASI) scores.ResultsThe patients showed an improvement in the PASI score and a significant decrease in serum hs-CRP, omentin, and chemerin values. Moreover, at the start of the follow-up, the psoriasis patients had significantly lower levels of adiponectin and visfatin and significantly higher levels of vaspin and resistin than those of the control group. Visfatin levels correlated negatively with low-density lipoprotein (LDL) and cholesterol, while vaspin and omentin levels correlated positively with diastolic blood pressure. Decreased adiponectin levels correlated negatively with diastolic blood pressure and LDL.ConclusionPlasma levels of adipokines might be useful for evaluating the disease activity of psoriasis and its comorbidities.
