Abstract：

Objective To investigate the association of HLA-A and -B alleles with syphilis in Shandong Han population. Methods The allele frequencies of HLA-A and -B were detected in 205 patients with syphilis and 5844 normal human controls by PCR-sequence specific oligonucleotide probe (PCR-SSOP)method. Results The patients with syphilis showed a higher frequency of HLA-A*02, B*15, B*40 alleles(all P＜0.01, Pc＜0.05) and a lower frequency of HLA-A*26 allele (P= 0.003, Pc = 0.039) than the normal human controls did. There was an increased frequency of HLA-B*15 and B*40 alleles in patients with symptomatic syphilis (both P＜0.01, Pc＜0.05), as well as an elevated frequency of HLA-A*02, 11, 29, B*15 and 40 alleles (all P＜0.01, Pc＜0.05) and a decreased frequency of HLA-A*30 and 33 in patients with asymptomatic syphilis(P=0.002, 0.026, Pc=0.001, 0.013 respectively), compared with the normal human controls. The frequency of HLA-A*30 allele was significantly higher in patients with symptomatic syphilis than in those with asymptomatic syphilis (P = 0.001, Pc = 0.013). Conclusions There seems to be an association between HLA-A*02, B* 15 and B*40 alleles and syphilis, between HLA-A*30 allele and symptomic syphilis, and between HLA-A*02, 11 and 29 alleles and asymptom1atic syphilis, in Shandong Han population.

Critical role of environmental factors in the pathogenesis of psoriasis

Psoriasis is a common cutaneous disease with multifactorial etiology including genetic and non‐genetic factors, such as drugs, smoking, drinking, diet, infection and mental stress. Now, the role of the interaction between environmental factors and genetics are considered to be a main factor in the pathogenesis of psoriasis. However, it is a challenge to explore the mechanisms how the environmental factors break the body balance to affect the onset and development of psoriasis. In this article, we review the pathogenesis of psoriasis and summarize numerous clinical data to reveal the association between environmental factors and psoriasis. In addition, we focus on the mechanisms of environmental risk factors impact on psoriasis and provide a series of potential treatments against environmental risk factors.

Risk factors for psoriasis: A case–control study

A case–control study of 110 consecutive psoriatic outpatients and 200 unmatched controls was carried out in order to analyze the association of psoriasis with smoking habits, alcohol consumption, family history of psoriasis and stressful life events. Stressful life events were assessed with Paykel's Interview for Recent Life Events, a semi-structured interview covering 63 life events. According to our results, the risk of psoriasis is higher in urban dwellers (odds ratio [OR] = 3.61; 95% confidence interval [CI] = 0.99–13.18), patients who were divorced (OR = 5.69; 95% CI = 2.26–14.34) and those exposed to environmental tobacco smoke at home (OR = 2.29; 95% CI = 1.12–4.67). Alcohol consumption (OR = 2.55; 95% CI = 1.26–5.17), family history of psoriasis (OR = 33.96; 95% CI = 14.14–81.57) and change in work conditions (OR = 8.34; 95% CI = 1.86–37.43) are also risk factors for psoriasis. Separate analyses for men and women showed that the risk of developing psoriasis was stronger in men with a family history of psoriasis (OR = 30.39; 95% CI = 6.72–137.42) than in women (OR = 16.99; 95% CI = 7.21–40.07). The effect of environmental tobacco smoke at home was found only in women (OR = 2.44; 95% CI = 1.26–4.73). Future well-designed epidemiological studies need to be performed in order to determine whether lifestyle factors and stress could be risk factors triggering or aggravating psoriasis.     

Relationship between environmental factors,age of onset and familial history in Japanese patients with psoriasis

Psoriasis is a chronic inflammatory disease that often involves the skin and joints. Psoriasis develops at any age and the distribution of age of onset of psoriasis is bimodal in Japan. Also, male predominance is distinct in Japanese psoriatic patients. To clarify the relationship between sex difference and habitual/environmental status, age and incidence of familial psoriasis, we analyzed data from the Fukuoka University Psoriasis Registry. A total of 1120 Japanese patients (751 men, 369 women) were analyzed. The male/female ratio was 2.03:1. Smoking and drinking habit, known as risk factors of psoriasis, were significantly more prevalent in men. Age‐specific psoriasis‐onset rate standardized by population showed bimodal distribution in both men and women; the younger peak was in their 30s for men and 10s in women; the second peak was in the 50s for both sexes. A familial history of psoriasis was seen in 6.3% of patients overall; however, female patients showed a significantly higher rate (8.7%) compared with men (5.1%, P = 0.024). When stratified by age of onset, the frequency of familial history was much higher among women with onset at less than 30 years (15.4%), compared with 30 years or more (5.3%, P = 0.0026). Our data suggest that genetic factors have a stronger influence in young women who experience fewer environmental factors such as smoking and drinking. This is the first study to show that there is a difference in the incidence of familial psoriasis depending on age of onset of psoriasis in Japan.     

Potentially modifiable risk factors for adverse pregnancy outcomes in women with psoriasis

Background Data on pregnancy outcomes among women with psoriasis are lacking. However, there are several known comorbidities of psoriasis, including obesity, smoking and depression, each of which increases the risk for negative birth outcomes. Objectives To determine if pregnant women with psoriasis have an excess of potentially modifiable risk factors for adverse pregnancy outcomes. Methods Prospectively collected data from the Organization of Teratology Information Specialists (OTIS) Autoimmune Diseases in Pregnancy Project were analysed to compare the prevalence of selected risk factors between 170 pregnant women with psoriasis and 158 nondiseased controls. Results Women with psoriasis were more likely to be overweight/obese prior to pregnancy (P < 0·0001), to smoke (P < 0·0001), or to have a diagnosis of depression (P = 0·03), and were less likely to have been taking preconceptional vitamin supplements (P = 0·004). After controlling for race/ethnicity and socioeconomic status, women with psoriasis were 2·37 (95% confidence interval 1·45–3·87) times more likely to be overweight/obese as women without psoriasis. Duration of disease, age at onset, measures of disease impact during pregnancy, or use of biologics in pregnancy were not significant predictors of overweight/obesity in the subset of psoriatic women. Conclusions Pregnant women with psoriasis may be at increased risk for adverse pregnancy outcomes due to comorbidities or other health behaviours associated with the disease. These should be taken into consideration during clinical treatment of women with psoriasis who are in their childbearing years.

Incidence of risk factors for myocardial infarction and other vascular diseases in patients with psoriasis

Background Recent cross‐sectional studies reported a higher prevalence of diabetes and other risk factors for cardiovascular disease in patients with psoriasis than in the general population. Objectives To estimate the cumulative incidences of risk factors for myocardial infarction and other vascular diseases after a first recorded diagnosis of psoriasis and the hazard ratio (HR) for these conditions in patients with psoriasis compared with the general population. Methods We used the General Practice Research Database to conduct a cohort study of 44 164 patients with a first‐time diagnosis of psoriasis and 219 784 nonpsoriasis comparison subjects psoriasis‐matched on age, sex and index date. Results HRs were increased among patients with psoriasis vs. the comparison cohort for incident diabetes [HR 1·33; 95% confidence interval (CI) 1·25–1·42], hypertension (HR 1·09; 95% CI 1·05–1·14), obesity (HR 1·18; 95% CI 1·14–1·23) and hyperlipidaemia (HR 1·17; 95% CI 1·11–1·23). Patients with psoriasis also had higher risks of incident myocardial infarction (HR 1·21; 95% CI 1·10–1·32), angina (HR 1·20; 95% CI 1·12–1·29), atherosclerosis (HR 1·28; 95% CI 1·10–1·48), peripheral vascular disease (HR 1·29; 95% CI 1·13–1·47) and stroke (HR 1·12; 95% CI 1·00–1·25). Conclusions Risk factors for cardiovascular disease as well as myocardial infarction and other vascular diseases occur with higher incidence in patients with psoriasis than in the general population. Further work is needed to investigate whether these associations involve causal factors related to psoriasis or its treatment.
