Abstract

Psoriasis is a common, chronic, immune mediated disorder.The disease is arising as a result of dysregulated interactions of the innate and adaptive immune system in the context of skin epithelium and connective tissue. The biological drug Etanercept(ETN) approved for use in treated psoriasis. ETN is tumor necrosis factor- α (TNF-α) inhibitor. In this study, 48 psoriatic patients were taken before and after treatment who attended to the Dermatology and Venereology Department in Baghdad Teaching Hospital during the period from December 2016 to September 2017and 50 samples were used as healthy control group. The results showed that most psoriatic patients 52.08 % were within the second and third decades 20-35 year, and the majority of psoriatic patients were males 62.5% and the ratio of male to female is 1.67:1. Moreover, the results demonstrated that the males were more expected psoriasis compare with females. Blood samples were collected and TNF- α was estimated in sera of all subjects by using Enzyme Linked Immunosorbent Assay (ELISA). The TNF- α mean levels in psoriatic patients before treatment was 189.5±26.0 ng/ml, and after treatment was 223.6±41.1 ng/ml compar with the healthy control group 93.5±2.4 ng/ml. The results showed significant differences between the studied groups

Abstract

Summary:Background: Cytokines produced by inflammatory cells play a pivotal role in synovial inflammation and joint destruction in rheumatoid arthritis.Patients and Methods: The cytokine serum levels were measured by EASIA (Enzyme amplified sensitivity immunoassay) in sera from 50 RA patients, and 40 healthy donors. Cytokine levels were compared in different RA subpopulations (positive or negative rheumatoid factor (RF), long term or recent onset disease, high or low disease activity). In addition, the possible association with other demographic and clinical parameters (gender, age, etc) was also analyzed. Results: It was demonstrated that IL-2, IL-6 and IFN-δ levels were elevated in serum samples of RA patients as compared with apparently healthy controls. Maximum elevation of TNF-α was recorded in a few number of patient's sera. There were non significant differences between control and RA patient groups in serum TNF-α level. Conclusions: Assessing the serum IL-2, IL-6, IFN-δ and TNF-α levels may be helpful in the confirmation of the RA activity. Due to the chronic course of this disease, other inflammatory markers must be identified in order to provide early therapeutic strategies to these patients.Key words: Rheumatoid Arthritis, Interleukine-2, Interleukine-6, Tumor Necrosis Factor- α, Interferon- δ.

Abstract

Background and objective: Chronic periodontitis is a multifactorial inflammatory disease characterized by destruction of tooth supporting tissues. Tumor necrosis factor-α, a key inflammatory cytokine, plays an important role in periodontal destruction. This study aimed to analyze the effect of non-surgical periodontal treatment on tumor necrosis factor-α levels in serum of patient with chronic periodontitis (with and without using chlorhexidine 0.2% mouthwash).Methods: A total of 44 patients with moderate to severe localized chronic periodontitis were divided into: Group I (n=22) without using of chlorhexidine mouthwash and Group II (n=22) with 0.2% chlorhexidine mouthwash. Serum samples collected from each subjectsat baseline and four weeks after scaling and root planning treatment were quantified fortumor necrosis factor-α levels using ELISA technique.Results: The mean concentration of TNF-α were significantly reduced one month after treatment in sera of patients with chronic periodontitis for group I when compared to its mean concentration before treatment (P <0.05), while in group II a highly significant reduction after one month treatment (P <0.001) was observed.Conclusion: The effect of non-surgical periodontal therapy with chlorohexidine mouth wash showed more reduction in the levels of serum tumor necrosis factor-α.

Abstract

Abstract :The aim of this study was to determine the Th1 and Th2 serum cytokines, in patients with psoriasis and to compare their cytokine levels with those of normal control subjects. where study included 55 Iraqi patients with psoriasis:30 (15 females ,15 males) were untreated with any drugs. The other patient group consist of 25 (9 female and 16 male) treated with a biological treatment (infliximab) ,and 30 healthy control group were withdrawn (5) ml of venous blood for both patients and members of the control ,to conduct Immunological tests to determine the quantitative for each of level of IL-2,IL-10 and TNF-α in a manner (ELISA). The results showed significant increase in the level of probability (P <0.05) in the rate of level of IL-10 and TNF-α in patients compared to the control (healthy) .As well as the result also show no significant increases of IL-2.From this we can deduce that pro inflammatory and anti-inflammatory cytokines have an important role in the pathogenesis of psoriasis, the increase of IL-10 and TNF-α indicated the balance between the proinflammatory and the anti-inflammatory cytokine .

Abstract

Background: Chronic periodontitis is an inflammatory disease of bacterial etiology that results in the destruction of tooth supporting tissues, tooth mobility, and tooth loss. The inflammatory response of the periodontal tissues to infection is influenced by environmental and genetic factors. The polymorphism of tumor necrosis factor-alpha (TNF-α) has been reported to influence the expression of TNF-α, thereby playing a role in the pathogenesis of periodontitis.Objective: To study the genotyping of tumor necrosis factor-α at position (-308) and to find out whether any associations exist between the severity of periodontitis and the gene polymorphisms.Patients and Methods: The study groups included 50 patients with chronic periodontitis and 20 healthy controls with clinically healthy periodontium with an age range of 25-50. Everyone were analyzed for polymorphism of TNF-α gene at position (-308). Periodontal parameters used in this study were plaque index (PLI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and bleeding on probing (BOP). Five ml of venous blood was collected from all patients and controls. DNA was extracted from blood samples, and then the results of electrophoresis of polymerase chain reaction (PCR) products for this cytokine were subjected for sequencing and to locate the positions of possible mutations.Results: The results of sequencing for the tumor necrosis factor-α gene showed higher frequency of mutations in patient samples as compared to healthy control samples. A highly significant difference was found in the frequency of mutations among the six samples (4 patients and 2 controls) p=0.0002.Conclusion: The results of this study indicates that the (-308) polymorphism in TNF-α gene is associated with the susceptibility to chronic periodontitis.

خلفية الدراسة: مرض النساغ المزمن هو مرض التهابي من المسببات البكتيرية التي تؤدي إلى تدمير الأنسجة الداعمة للأسنان ، حركة الأسنان، وفقدان الأسنان. الاستجابة الالتهابية لأنسجة الاسنان الداعمة للاصابة تتأثر بالعوامل البيئية والوراثية.أن تعدد الأشكال لعامل نخر الورم ألفا (TNF-α) له تأثير على التعبير عن TNF-α، وبالتالي تلعب دورا في التسبب في التهاب اللثة.اهداف الدراسة : قد أجريت هذه الدراسة لدراسة التنميط الجيني لعامل نخر الورم α في موضع (-308) ولمعرفة ما إذا كان هناك أي أرتباط موجودة بين شدة التهاب اللثة وتعدد الأشكال الجيني.المرضى والطرائق : شملت مجموعات الدراسة 50 مريض لديهم التهاب اللثة المزمن و 20 الاصحاء مع لثة صحية سريريا وكانت أعمارهم تتراوح ما بين25- 50 سنة. اما فيما يخص مؤشرات ما حول الاسنان التي تم قياسها في هذه الدراسة هي (مؤشر الصفيحة الجرثومية , مؤشر التهاب اللثة , عمق جيوب اللثة , مستوى الانسجة الرابطة سريريا و مؤشر النزف عند التسبير). تم جمع خمسة مل من الدم الوريدي من جميع المرضى والضوابط. تم استخراج الحمض النووي (DNA) من عينات الدم ثم بعد ذلك أُجري الترحيل الكهربائي من منتجات تفاعل البلمرة المتسلسل (PCR) ، وأُرسلت النتائج لمعرفة التتابعات وتحديد اماكن الطفرات المحتملة.النتائج: أظهرت نتائج الكشف عن تسلسلات القواعد النتروجينية لجين عامل نخر الورم ألفا ((TNF-α تردد أعلى من الطفرات في عينات المرضى مقارنة عينات من الأصحاء. تم العثور على اختلاف كبير جدا في تردد الطفرات بين العينات الست (4 مرضى و2 الضوابط) p=0.0002.الاستنتاجات: نتائج هذه الدراسة تشير إلى أن تعدد الأشكال في الجين TNF-α في موضع (-308) يمكن أن تسهم في زيادة القابلية لمرض النساغ المزمن.
