ABSTRACT
Objective To detect the levels of procalcitonin in multiple genes autoinflammatory disease (adult Still disease,systemic juvenile idiopathic arthritis,crohn's Crohn's disease),and to explore the relationship between erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),ESR/CRP and disease or complicated infection combined disease.Methods One hundred and fifty-three patients were en-rolled,88 patients with multiple genes autoinflammatory disease,including 32 cases of adult Still disease,27 cases of systemic juvenile idiopathic arthritis,29 cases of Crohn's disease.In addition,30 cases of healthy controls,35 patients with systemic lupus erythematosus (SLE) were included into this study.Electroche-miluminescence was used to test the value of serum PCT,erythrocyte sedimentation rate was tested by blood sedimentation instrument method,the CRP level was tested by lmmunoturbidimetry,and the data was handed managed and analysised by matlab software and One-way analysis of variance (ANOVA) was used to compare the differences of PCTs between groups.Results ① In the non-infection condition,the PCT value of the autoimmune inflammatory diseases [(0.36±0.74) μg/L,95％confidence interval (CI) (0.174 9,0.550 9) μg/L)] was signifieantly higher than that of the healthy control group [(0.06±0.06) μg/L,95％CI (0.035 1,0.081 7 μg/L)],the difference was statistically significant (F=5.03,P=0.027 4),but there was no statistically significant (F=1.03,P=0.475 5) when comparing with SLE group.② The PCT level of the non-infected inflammatory enteric arthritis [(0.20±0.32),95％CI(0.042 7,0.364 3) μg/L] was different compared with the healthy group,the difference was statistically significant (F=5.77,P=0.020 4),at the same time,the difference was not statistically significant when comparing with the SLE group (F=0.22,P=0.647 6).When the PCT value in non-infected adults Still disease [(0.60±1.02) 95％CI(0.048 4,1.153 6) μg/L] compared with the healthy group,the difference was statistically significant (F=7.22,P=0.01) but the difference was not statistically different when compared with the SLE group (F=2.65,P=0.114 3).The PCT level difference was statistically significant (F=2.23,P＜0.01)when comparing infection-free juvenile idiopathic arthritis [(1.52±2.02) μg/L,95％CI(0.054 8,4.591 9) μg/L] and the healthy group,the difference was statistically significantly different (F=8.34,P=0.004 7) when compared with the PCT of the non-infected SLE group.③ In the case of autoinflammatory diseases without infection,the 95％CI of ESR/CRP ratio was between 1.121 2 and 3.589 4.In the case of co-infection,the 95％ CI of ESR/CRP ratio was between 1.502 2 and 8.718 8,so we considered autoimmune inflammatory diseases might had a high possibility of co-infection when the ESR/CRP ratio was higher than 3.5.Conclusion ① The multiple genes autoinflammatory disease group has a higher value of PCT level than healthy controls even without infection.② The mean and 95％CI range of PCT of the inflammatory bowel disease arthritis,adult Still disease and the juvenile id-iopathic arthritis is significantly higher than the healthy controls,partially higher than SLE group.In addition,the PCT level in the juvenile idiopathic arthritis is the highest.③ In clinical,to estimate whether the multiple genes autoinflammatory disease has bacterial infection,we can't just simply rely on PCT to estimate whether the multiple genes autoinflammatory disease has bacterial infection,we may consider the ratio of the ESR/CRP,when the value is higher than 3.5,we may consider patients has strong probability with infection.
ABSTRACT
Human beings have taken successive approaches for the understanding and management of diseases. Initially brewed in supernatural concepts and mystical procedures, a vigorous scientific approach has emerged on the grounds of fundamental disciplines such as anatomy, microbiology, biochemistry, physiology, immunology, pathology, and pharmacology. The resulting integrated knowledge contributed to the current classification of diseases and the way Medicine is carried out today. Despite considerable progress, this approach is rather insufficient when it comes to systemic inflammatory conditions, such as systemic lupus erythematosus, that covers clinical conditions ranging from mild pauci-symptomatic diseases to rapidly fatal conditions. The treatment for such conditions is often insufficient and novel approaches are needed for further progress in these areas of Medicine. A recent breakthrough has been achieved with respect to chronic auto-inflammatory syndromes, in which molecular dissection of underlying gene defects has provided directions for target-oriented therapy. Such approach may be amenable to application in systemic auto-immune diseases with the comprehension that such conditions may be the consequence of interaction of specific environmental stimuli and an array of several and interconnected gene polymorphisms. On the bulk of this transformation, the application of principles of pharmacogenetics may lead the way towards a progressively stronger personalized Medicine.
O homem tem buscado sucessivas abordagens para o entendimento e manejo das doenças. Partindo de conceitos sobrenaturais e procedimentos místicos, uma abordagem científica vigorosa vicejou com base em disciplinas fundamentais como a anatomia, microbiologia, bioquímica, fisiologia, imunologia, patologia e farmacologia. O conhecimento integrado resultante contribuiu para a atual classificação das doenças e a formacom que a Medicina atual é praticada. Apesar deste considerável progresso, esta abordagem é insuficiente quando se trata de condições inflamatórias sistêmicas, como o lúpus eritematoso sistêmico, que abrange condições variando de formas brandas e pauci-sintomáticas até condições rapidamente fatais. O tratamento dessas condições é frequentemente insuficiente e novas abordagens são necessárias para progresso adicional nessas áreas da Medicina. Um avanço recente foi obtido no que tange às síndromes auto-inflamatórias hereditárias, nas quais a dissecção molecular dos defeitos gênicos subjacentes forneceu direcionamento para terapia orientada a alvos moleculares específicos. Esta abordagem é passível de aplicação às doenças auto-imunes sistêmicas com a compreensão de essas condições podem ser conseqüência da interação de estímulos ambientais específicos e uma gama de vários polimorfis mosgênicos interconectados. No escopo dessa transformação, a aplicação dos princípios de farmacogenéticas poderá contribuir para o progressivo desenvolvimento de uma Medicina personalizada vigorosa.
