Abstract
BACKGROUND Colon cancer (CC) is one of the most common malignancies worldwide. Characterization of new prognostic biomarkers for right-sided CC (RCC) and left-sided CC (LCC) may contribute to improving early detection. An association of human leukocyte antigens class II (HLA-II) with the predisposition to CC was suggested. AIM OF THE STUDY We evaluated the association of DRB1 and DQB1 with the risk of LCC and RCC. PATIENTS AND METHODS Our study comprised 93 CC patients and 100 healthy controls. Genotyping of HLA class II alleles were performed by the Polymerase Chain Reaction Sequence-Specific Primers (PCR-SSP). RESULTS DRB1*03 was positively associated with CC. In contrast, DRB1*11, DRB1*13, DQB1*03, and DQB1*05 were negatively linked to CC. Haplotype analysis revealed that DRB1*04-DQB1*04 and DRB1*09-DQB1*02 were positive, while DRB1*01-DQB1*05, DRB1*04-DQB1*03, DRB1*07-DQB1*02, DRB1*11-DQB1*03, DRB1*11-DQB1*05, and DRB1*13-DQB1*06 were negatively associated with CC. For sigmoid CC, DRB1*13, DRB1*11, and DQB1*05 were negative, while DRB1*04-DQB1*02, and DRB1*07-DQB1*03 were positively associated. DRB1*03 and DRB1*04-DQB1*04 were positive, while DRB1*11 and DQB1*03 were negatively linked to RCC. According to the LCC, DRB1*07, DRB1*11, DQB1*03, DQB1*05, and DRB1*07-DQB1*02 were negative. In contrast, DRB1*09-DQB1*02 was positively associated with LCC. Stratified analysis revealed that DRB1*11 is associated with higher risk of metastasis in CC and sigmoid CC, and tolerance to treatment in RCC. DQB1*03 was associated with lymph-node invasion in CC. CONCLUSION DRB1 and DQB1 polymorphisms could be used as future biomarkers for the early detection of subjects at a higher risk of developing RCC and LCC, metastasis in sigmoid CC, and tolerance to treatment in RCC.

Abstract
CONTEXT Chronic rheumatic diseases seem to be associated with a higher risk of developing cardiovascular diseases. The link between cytokines and lipid profile in spondyloarthritis is not well elucidated. AIMS We aimed to assess the relationship between cytokines and obesity, lipid profile and atherogenic indexes in spondyloarthritis. METHODS AND MATERIAL We conducted a cross-sectional study including 45 patients with axial radiographic spondyloarthritis. For each patient, we measured the following pro-inflammatory cytokines: interleukin (IL-) 1, IL-8, IL-6, IL-17, IL-23 and tumor necrosis factor a (TNFa), and anti-inflammatory cytokines: IL-10. We also measured total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDLc) and low-density lipoprotein cholesterol (LDLc). We calculated the following ratios: TC/HDLc, TG/HDLc, LDLc/HDLc and Log[TG/HDLc]. STATISTICAL ANALYSIS USED SPSS. RESULTS The mean age was 46 ± 11.9 years. IL-8 levels were increased in obese patients (P = 0.003). IL-8 and IL-22 levels were significantly higher in patients with abdominal obesity (P = 0.024 and P = 0.042, respectively). IL-6 levels were lower in patients with hypercholesterolemia (P = 0.009). IL-1 levels correlated to TG (r = 0.413; P = 0.005). IL-1 and IL-6 were correlated to TG/HDLc (IL-1: r = 0.484, P = 0.001; IL-6; r = 0.700, P = 0.012) and Log[TG/HDLc] (IL-1: r = 0.354; P = 0.012; IL-6: r = 0.309, P = 0.041). IL-10 level was correlated to TC/HDLc (r = 0.333, P = 0.027) and LDLc/HDLc (r = 0.342, P = 0.023). CONCLUSIONS IL-8 and IL-22 were higher in patients with abdominal obesity, highlighting the contribution of the adipocytes to the secretion of pro-inflammatory cytokines. The correlation between cytokines and atherogenic indexes suggests the role of these cytokines in the occurrence of cardiovascular diseases in spondyloarthritis.

Abstract
BackgroundPhysipathological mechanisms of spondyloarthritis (SA) are very complex. The role of the interleukin (IL)- 8, which is an angiogenic chemokine, has been suggested [1].ObjectivesWe aimed to evaluate the discriminative value of interleukin 8 in SA.MethodsWe conducted a cross-sectional study during two years (2019-2020) including 144 subjects divided into two groups: a group G1 that included 72 patients followed for spondyloarthritis meeting the Assessement of SpondyloArthritis international Society (ASAS) criteria and a group (G2) including 72 healthy controls. The two groups were matched by age and sex.IL-8 was measured for each participant using chemiluminescence.We performed a ROC analysis and computed the air under the curve (AUC) at IL-8 to assess the ability of this chemokine to diagnose SA and to distinguish between SA patients from healthy controls. Statistical analysis was performed using SPSS.ResultsWe included 57 men and 15 females in each group. The mean age was 44.84 ± 13.42 years. In G1, the mean disease duration was 10.25 ±7.7 years. Axial and peripheral involvements were found in 85% of cases (n=65) and 50% of cases, respectively.The mean BASDAI and ASDAS-CRP were 3.21 ± 1.87 and 2.92 ±1.55, respectively.IL-8 was able to distinguish SA patients from healthy controls with a cutoff of 4.5 pg/mL. The AUC was good at 0.855 (p<0.0001). The sensibility and the specificity were 92.8% and 81.6% (Figure 1).Figure 1.AUC at IL-8 between SA patients and healthy controls 0.855 (p<0.0001)ConclusionSeveral studies have found that IL-8 was significantly higher in SA patients comparing to controls [2,3]. Our study showed that IL-8 could distinguish SA patients from controls with a cutoff of 4.5 pg/mL. This suggests that IL-8 could play a role in the pathophysiology of SA.References[1]König A, Krenn V, Gillitzer R, Glöckner J, Janssen E, Gohlke F, et al.

Abstract
The severity of COVID-19 is largely determined by the inflammatory response, a “Cytokine storm,” that involves both pro- and anti-inflammatory cytokines. In the current study we investigated the balance of pro- and anti-inflammatory status as represented by the levels of IL-6/IL-10 in severe to critical COVID-19 patients. 66 confirmed COVID-19 patients admitted to the ICU were categorized into groups according to the mortality and respiratory failure. Data were collected retrospectively in ICU, including a peripheral immune cells and infection-related biomarker CRP. The measurements of cytokine levels were performed by Immulite analyzer for IL-6 and ELISA sandwich for IL-10. In addition, longitudinal measurement of IL-6 was performed during 5 days post admission. Longitudinal assays showed that IL-6 was sustained at a medium level within 5 days post admission in severe cases who survived or not requiring mechanical ventilation, whereas it was sustained at high levels throughout the disease course in either deceased cases or who developed respiratory failure. The ratio of IL-6/lymphocytes was positively correlated with the risk of mortality, while IL-10/lymphocytes ratio could predict respiratory failure in ICU. IL-6/IL-10 profiling revealed that deceased patients have different magnitudes of both IL-6 and IL-10 cytokine release. Notably, excessive levels of IL-6 concomitant with high levels of IL-10 were more common in diseased COVID-19 patients. Taking into account the IL-6/IL-10 profiling may help clinicians to identify the right time of anti-inflammation treatment and select patients who will respond to anti-cytokine therapies and maintain an adequate inflammatory response for SARS-CoV-2 clearance.

Abstract
The SARS CoV-2 pandemic is a global health threat with high morbidity and mortality (1 to 4%) rates. COVID-19 is correlated with important immune disorders, including a “cytokine storm”. A new therapeutic approach using the immunomodulatory drug, Anti-IL6 (tocilizimub), has been proposed to regulate it. We report here the first Tunisian experience using tocilizimub in two severe cases of COVID-19 pneumonia. The diagnosis was confirmed by chest scan tomography. Biological parameters showed a high level of Interleukin-6 (IL-6) that increased significantly during hospitalization. The patients developed hypoxia, so they received intravenously 8 mg/kg body weight tocilizumab. There was a resultant decrease in the level of IL6, with clinically good evolution. Blocking the cytokine IL-6 axis is a promising therapy for patients developing COVID-19 pathology.

Abstract
Background:Common low back pain (LBP) is a common health problem affecting 50 to 80% of working age adults. It is one of the common and costly health problems in Tunisia. Actually, the role of the immune response and inflammatory cytokines in the pathogenesis of chronic pain has been of growing interest.Objectives:The aim of this study was to assess whether pro and anti-inflammatory cytokines could be detected in serum in patients with LBP compared with healthy subjects and whether they could be related to pain severity and to clinical findings.Methods:It was a an analytical cross-sectional study including 50 patients with at least three months of LBP, in the department of rheumatology, orthopedics and immunology at the Military Hospital of Tunis between January 1st and March 31, 2020. All patients had a standardized clinical assessment.Levels of serum cytokines IL-6, IL-8, IL-1β and TNF- α, were measured using the chimiluminescence technique. Serum concentration of IL-10 was assayed by the enzyme-linked immunosorbent assay technique (ELISA). The normal levels of cytokines were determined in 50 healthy controls.Results:The mean age of the patients was 41.9 ± 8.4 years and the sex ratio was 4.5. LBP duration was 66.4 months. The mean lumbar visual analog scale (VAS) was 4.5 ± 1.9, and the root VAS was 2.6 ± 2.5. Neuropathic pain was found in 26% of patients. The average BMI was 27 ± 3.7 kg/m2. Only serum level of IL-8 was significantly higher in subjects with LBP compared to healthy controls (p <10-3). IL-1β was indetectable in both patients and controls. Positive correlations were found between IL-8 levels and anxiety/functional scores (r = 0.3; p = 0.02/ r = 0.3; p = 0.04). IL-6 was positively correlated with BMI, and negatively correlated with the Schober test. No correlations were found between serum levels of IL-6, IL-8, IL-10, TNF-α and pain intensity (VAS), neuropathic pain (DN4), fibromyalgia (FIRST), depression (HAD) and various radiological data.Conclusion:Interleukin-8 is a biomarker of common low back pain and correlate with anxiety and functional disability. These results suggest that IL-8 may be a therapeutic target to reduce chronic back pain and reduce the social and profession impact.Disclosure of Interests:None declared

Abstract
Background:Interleukin 17 (IL-17) is pro-inflammatory cytokine that plays a crucial role in spondyloarthritis via the Th17/IL-17 axis. (1)Objectives:We aimed to study the diagnosis value of IL-17 serum in spondyloarthritis.Methods:We conducted a case-control study, including 104 subjects divided into 2 groups:-G1: 52 patients meeting the Assessment of SpondyloArthritis International Society (ASAS) criteria for spondyloarthritis (SA)-G2: 52 healthy controls matched for age and sex.The IL-17 level was measured using Enzyme-linked immunosorbent assay (ELISA).We performed a ROC analysis and computed the air under the curve (AUC) at IL-17 to assess the ability of IL-17 to diagnose SA.Statistical analysis was performed using “IBM SPSS Statistics” software version 25.Results:Eighty per cent of the patients were men (n=41). The mean age was 44.96 ± 13.09 years. The mean age at the onset of the disease was 35.07 ± 12.66 years. The disease duration was 9.25 ± 8.09 years. Axial radiographic spondyloarthritis and peripheral involvement were found in 53.8% (n=28) and 44.2% (n=23) of cases, respectively. Psoriasis was noted in 46% of cases (n=24). The mean ASDAS-CRP was 3.21 ± 1.64.IL-17 level was significantly higher in patients compared to healthy controls (92.76 ± 71.85 pg/mL and 2.67 ± 9.01 pg/mL, respectively, p<0.0001).As shown in Figure 1, the AUC value to distinguish between spondyloarthritis and healthy control was 0.987 (p<0.0001). IL-17 cut-off was 13.79 pg/mL (Sensibility= 94.2%, specificity=98.1%).Figure 1.AUC at IL-17 between SA patients and healthy controls 0.987 (p<0.0001)Conclusion:According to previous studies, our study showed that serum IL-17 level is significantly higher in SA patients compared to healthy controls (2).Interestingly, IL-17 was able to distinguish between SA patients and healthy controls with a cut-off of 13.79 pg/mL. This finding suggests that IL-17 may be useful for the diagnosis of SA.References:[1]Ruiz de Morales JMG, Puig L, Daudén E, Cañete JD, Pablos JL, Martín AO, et al.

Abstract
Background:Interleukin 23 (IL-23) is a pivotal pro-inflammatory cytokine in the Th17/IL-23 axis which became the center of attention in researches during these last decades, especially during spondyloarthritis (1).Objectives:We aimed to study the diagnosis value of IL-23 serum in spondyloarthritis.Methods:We conducted a case-control study, including 144 subjects divided into 2 groups:-G1: 72 patients meeting the Assessment of SpondyloArthritis International Society (ASAS) criteria for spondyloarthritis (SA)-G2: 72 healthy controls matched for age and sex.For each SA patient we collected the following parameters: BASDAI (Bath Ankylosing Spondylitis Disease Activity Index), ASDAS (Ankylosing Spondylitis Disease Activity Score), BASFI (Bath Ankylosing Spondylitis Functional Index), and BASRI (Bath Ankylosing Spondylitis Radiology Index).The IL-23 level was measured using Enzyme-linked immunosorbent assay (ELISA).Erythrocyte Sedimentation rate (ESR) and C-reactive protein (CRP) were also measured.We performed a ROC analysis and computed the air under the curve (AUC) at IL-23 to diagnose SA patients.Statistical analysis was performed using “IBM SPSS Statistics” software version 25.Results:The study included 57 men and 15 women. The mean age was 44.84 ± 13.42 years. The mean age at the onset of the disease was 35.97 ± 12.88 years. The disease duration was 8.54 ± 7.7 years.Seventy-nine per cent of our patients had axial radiographic spondyloarthritis (n=57). Peripheral involvement was found in 45.8% (n=33). Eighteen patients had both axial and peripheral involvement concomitantly. Psoriasis was found in 36.1% of the cases (n=26).The mean BASDAI and ASDAS-CRP were 3.21 ± 1.64 and 3.05 ± 1.51, respectively.The mean was BASFI 3.88 ± 2.69. The mean was BASRI 5.26 ± 4.14.The mean ESR and CRP were 36.74 ± 29.38 mm/hr and 20.45 ± 25.19 mg/dL, respectively.IL-23 level was significantly higher in patients compared to healthy controls (23.1 ± 2.72 pg/mL and 5.02 ± 0.59 pg/mL, respectively, p<0.0001).As shown in Figure 1, the AUC value to distinguish between spondyloarthritis and healthy control was 0.705 (p<0.0001). IL-23 cut-off was 7.96 pg/mL (Sensibility= 69.4%, specificity=98.6%).Figure 1.AUC at IL-23 between SA patients 0.705 (p<0.0001) Nevertheless, no correlation was found between serum IL-23 levels and the following parameters: ESR, CRP, BASDAI, ASDAS-CRP, BASFI and BASRI.Conclusion:As reported to previous studies, our study showed that IL-23 is significantly higher in SA patients (2).Interestingly, IL-23 was able to distinguish between SA patients and healthy controls with a cut-off of 7.96 pg/mL. This finding suggests that IL-23 may be practical for the diagnosis of SA.References:[1]K V, D E.

Abstract
Background:The cardiovascular burden in inflammatory rheumatic diseases is well recognized. This burden has been reported in spondyloarthritis. Atherogenic indexes are known with their role of predicting cardiovascular risk.Objectives:The aim of our study was to determine the relation between pro-inflammatory cytokines and atherogenic indexes in spondyloarthritis.Methods:We performed a cross sectional study including 38 patients with spondyloarthritis according to ASAS criteria. For each patient we measured interleukin (IL)1, IL6, IL17, IL23 and tumor necrosis factor (TNF) alpha, total Cholesterol (CT), Triglycerides (TG), High density lipoprotein Cholesterol (HDLc) and Low density lipoprotein cholesterol (LDLc). We also calculated the following ratios: CT/HDLc, TG/HDLc, LDLc/HDLc, and LogTG/HDLc.Disease activity was measured using ASDAS (Ankylosing Spondylitis Disease Activity Score) and BASDAI (Bath Ankylosing Spondylitis Disease Activity Index).Statistical analysis was performed using IBM SPSS Statistics 25.Results:The mean age were 45.4±12.5 years. There were 33 Male (sex ratio were 6.6).The mean C-reactive protein(CRP) were 29.6 ±40.34mg/L, mean erythrocyte sedimentation rate(ESR) were 41±33.9mm.The mean ASDASCRP, BASDAI were 2.8±1.24, 3.7±2.12, respectively.Active disease were noted in 68 % of patients using ASDASCRP score.The mean IL1, IL6, IL17, IL23, TNF alpha were 11.6 ±25pg/ml, 15.4±45.9pg/ml, 84.6±77.9pg/ml, 15.3±15.26pg/ml, 25.3± 47.9pg/ml respectively.The mean CT,HDLc,LDLc, TG were 4.47±0.93mmol/l, 1.09±0.3mmol/L, 2.77±0.78mmol/L, 1.29±0.54mmol/L respectively.The mean CT/HDLc, TG/HDLc, LDL/HDLc, LogTG/HDLc were 4.28±1.26, 1.22±0.6, 2.7±1.06, 0.03±0.23, respectively.Correlations were found between TG/HDLC ratio and IL1 (p<0.01, r=0.515), IL6(p<0.05; r=0.407), Log TG/HDLc and IL1 (p< 0.05, r=0.369), and IL6(p<0.05; r=0.333)However, no correlations were noted between atherogenic indexes and IL7, IL17, IL23, TNFalpha.Conclusion:Our study showed a correlations between atherogenic indexes and both IL1 and IL6.These findings suggests that serum IL-6 and IL1 levels in spondyloarthritis contribute to the development of cardiovascular disease atherosclerosis.References:[1]Lau et al.

Abstract
Autoimmune hepatitis (AIH) is a chronic hepatitis of unknown etiology and several cytokines have been implicated in its pathogenesis and onset. Our objective was to determine the profile of pro and anti-inflammatory cytokines, including IL-1β, IL-6, IL-8, IL-23, IFN-, TNF-α, IL-10 in autoimmune hepatitis and their association with HLA gene polymorphisms. Serum cytokine levels were determined in 50 autoimmune hepatitis patients and one hundred fifty controls using chemiluminescence and ELISA techniques and HLA genotyping performed by PCR SSP. The levels of IL-6 (12 pg/mL vs. 5.5 pg/mL, p = 0.017), IL-8 (24.1 pg/mL vs. 7.8 pg/mL, p = 0.006), and TNF-α (61.1 pg/mL vs. <4.00 pg/mL, p = 0.002) were significantly higher in AIH patients in pretreatment phase compared to levels after remission and in controls. HLA*DRB15 was significantly associated with higher levels of IL-8. IL-6, IL-8, and TNF-α may be biomarkers of AIH activity. HLA gene expression may play a role in higher cytokine production and could allow an earlier diagnosis and better management of the disease.

Abstract
e12592 Background: Breast cancer is the second most common cancer and the fifth most common cause of cancer mortality worldwide. The functional relationship between inflammation and cancer is an old concept of cancero- genesis, and it is now clear that inflammatory process certainly potentiates and/or promotes neoplastic risk. However, many of the molecular and cellular mechanisms mediating this relationship remain unresolved. The aim of this study is to measure the level of circulating cytokines (IL17, IL6, IL22, IL23 and TNFα) in breast cancer patients in Tunisia, and to evaluate their implication as prognostic factors. Methods: Serum samples were collected prospectively from sixty breast cancer patients in Tunisia. TNF-α and IL6 levels were determined using the technique of a solid-phase, two-site chemo-luminescent enzyme immune-metric assay (Immulite 1000, USA). Serum levels of IL17, IL22 and IL23 were measured by enzyme-linked immunosorbent assays (ELISA) sandwich method. Results: The mean age of patients is 48 years, and fourth of them were metastatic. The mean level of cytokines IL6, IL17, TNFα, IL22 and IL23 were respectively 4.80 ± 7.26 pg/ ml (min 2, max 36.80 pg/ ml), 0.27 ± 0.69 pg/ ml (min 0, max 3.62 pg/ ml), 5.93 ± 2.27 pg/ ml (min 4, max 15.30 pg/ml), 50.82 ± 34.78 p/ml (min 26.48, max 199.48 pg/ ml) and 18.05 ± 30.91 pg/ ml (min 0, max 200.21 pg/ml). Serum IL6 level was significantly higher in advanced stages (p = 0.013), especially in metastatic cases (p = 0.001) and in patients who had recurrent disease (p = 0.010). High level of TNFα was also significantly associated with advanced stage (stage III and IV) (p = 0.019), and high level of IL22 was significantly associated with a high histopathological grade (Grade III of Bloom-Richardson grade (SBR)) (p = 0.028). IL23 was found to be significantly increased in lymph node metastatic cases (p = 0.042) and in young patients < 35 years (p = 0.034). Finally, the level of IL17 was significantly higher in patients who had recurrent disease (p = 0.018). Conclusions: Our results highlight the role of certain circulating cytokines as potential prognostic biomarkers in breast cancer patients. The serum analysis of these cytokines, which could contribute to tumor growth and progression, may help to identify groups of patients with poor prognosis and who may need more aggressive treatment. This correlation needs to be evaluated in large prospective validating trials and suggests a rational for the development and use of cytokine blockade in treatment of some groups of breast cancer patients.

Abstract
e15130 Background: Colorectal cancer is the third most common malignancy and fourth most common cause of cancer mortality worldwide. It is responsible for more than 600,000 deaths annually, and incidence rates are increasing in most of the developing countries. Pathophysiology implicates pro-inflammatory conditions that promote the tumor malignant progression, invasion, and metastasis. The aim of this study is to measure the level of circulating cytokines (IL1b, IL6, IL8, IL10, IL22, IL23 and TNFα) in sixty colorectal cancer patients in Tunisia and to evaluate their implication as prognostic factors. Methods: Serum samples were collected prospectively from a cohort of sixty colorectal cancer patients in Tunisia. Levels of circulating inflammatory cytokines, TNF-α, IL1b, IL6 and IL8 were measured using the technique of a solid-phase, two-site chemo-luminescent enzyme immune-metric assay (Immulite 1000, Simens, USA). Serum levels of IL10 were measured by enzyme-linked immunosorbent assays (ELISA) sandwich method. Results: The mean age of patients is 58 years (24–82 years), Thirty-sex among them were m and 24 women with sex ratio of 1.5. Twenty-five patients were at metastatic setting, and hepatic metastasis was found in 25% of cases. The mean level of cytokines Il6, IL10, TNFα, IL8 and IL1b were respectively 12.26 +/- 18.7 pg/ ml (min 2, max 117pg/ ml), 0.93 +/- 5.23 pg/ ml (min 0, max 39.35 pg/ml), 8.31 +/- 4.99 pg/ ml (min 4, max 27.20 pg/ ml), 61.9 +/- 159.71 pg/ml (min 5, max 1173 pg/ ml) and 1.13 +/- 3.34 pg/ ml (min 5, max 15.7pg/ml. We found a significant correlation between a high level of IL8 and metastatic disease (p=0.001), especially in mutant RAS cases (p=0.001). We found also a significant correlation between high level of IL1b and lymphovascular invasion (p=0.013) and young patients (p=0.01). On the other hand, there was significant correlation between IL8 and IL6 (r = 0.560, p = 0.00001); IL8 and TNFα (r = 0.404, p = 0.001); and IL10 with IL1b (r = 0.297, p = 0.021). Conclusions: Our results highlight the role of circulating IL8, TNFα, IL1b and IL10 as potential prognostic biomarkers in colorectal cancer patients. These cytokines could contribute to tumor growth and progression, namely for IL-8 level that was significantly correlated with poor prognosis and advanced stages. This correlation needs to be evaluated in large prospective trials and suggests a rational for the development and use of cytokine blockade in treatment of colorectal cancer patients.

Abstract
The physiopathology of autoimmune hepatitis (AIH) is complex and still not fully elucidated. The genes localized outside the histocompatibility complex involved in regulation and signal transduction of the immune system SH2B3, TGFβ1, STAT4 and PTPN22 could be associated to the susceptibility and hepatocyte lysis mechanism of this lethal autoimmune disorder. PATIENTS AND METHODS We investigated four polymorphic sites in SH2B3 (rs3184504), TGFβ1 (rs1800471), STAT4 (rs7574865) and PTPN22 (rs2476601) in 45 AIH patients and 150 healthy controls from Tunisia using real-time PCR. RESULTS Significant associations were found for SH2B3 T allele (OR = 1.861; p = 0.015, pc = 0.366) and PTPN22 A allele (OR = 7.070; p = 0.026; pc = 1.00) and AIH with opposite homozygous being protective against the disease (CC genotype with OR = 0.420, p = 0.025; GG genotype with OR = 0.136, p = 0.025, respectively). No statistically significant associations were found for the TGFβ1 and STAT4 polymorphisms with AIH susceptibility. CONCLUSION Our work enlarges information on non-HLA genes that are associated with AIH by focusing in a region of the world that was poorly molecularly characterized for this disease.

Abstract
OBJECTIVES Acute myocardial infarction (MI) leads to molecular, structural, geometric and functional changes in the heart during a process known as ventricular remodeling. Myocardial infarction is followed by an inflammatory response in which pro- and anti-inflammatory cytokines play a crucial role, particularly in left ventricular remodeling. This study aimed at evaluating serum concentrations of interleukin-8 (IL8), tumor-necrosis-factor-alpha (TNFα) and interleukin-10 (IL10), pro- and anti-inflammatory cytokines, and at correlating them with left ventricular remodeling as assessed by echocardiographic parameters. METHODS In a case-control study 30 MI patients were compared with 30 healthy controls. Serum concentrations of IL8, TNFα and IL10 were measured on day 2 and day 30 post-MI by chemiluminescence immunoassay and correlated with echocardiographic parameters. RESULTS There was an increase of IL8, and TNFα together with a decrease of IL10 at both time points. IL8 was negatively correlated with the left ventricular end-diastolic diameter (LVEDD) and positively with left ventricular systolic volume. IL10 was negatively correlated with LVEDD and left atrial volume 30days post-MI. CONCLUSION The increase of pro-inflammatory cytokines TNFα and IL8 was accompanied by decreased anti-inflammatory IL10. This imbalance between pro- and anti-inflammatory cytokines might contribute to the progression of left ventricular remodeling and may lead to heart failure.

Abstract
The present study was undertaken to investigate the association between Hepatitis B Virus (HBV) infection and polymorphisms of tumour necrosis factor alpha TNF-α -308 G>A, TNF-α -238 G>A and TNF RII VNTR (p75) gene promoter in a Tunisian population. Blood samples were collected from 100 Tunisian patients with HBV infection, 45 with Chronic Hepatitis (CH), 36 with Liver Cirrhosis (LC), 15 with Hepatocellular Carcinoma (HCC) and 200 healthy individuals of similar ethnicity. Genomic DNA was extracted from peripheral blood leukocytes. Genotyping of the analysed polymorphisms was performed using Amplified Refractory Mutation System-Polymerase Chain Reaction (ARMS-PCR), Restriction Fragment Length Polymorphism (RFLP) and Variable Number Tandem Repeat PCR (PCR-VNTR). The variant homozygotes -308 GG were associated with 50% decreased risk of HBV chronic infection (GG vs AA+GA; p=0.010; OR=0.50; 95%CI=0.29-0.85). However, the carriers of minor allele -308 A have higher risk (1.5 times) to develop a chronic infection than other patients (p=0.027; OR=1.46; 95%CI=1.04-2.06). The minor allele of -238 polymorphism was positively associated with virus resistance and the development of chronic infection (p=0.043; OR=1.42; 95%CI =1.01 1.99). The distribution of -308, -238 and TNF RII VNTR (p75) among the three groups differed significantly. For HCC groups, there were statistically significant differences in allele distribution in -308, -238 respectively in which A allele remains a risk factor for HBV evolution to HCC (p=0.008 and p=0.026). Haplotype analysis revealed that TNF-α (-308A; -238A) was significantly associated to HBV chronic infection and moreover to disease aggravation to HCC stage. Our findings imply that variations in the genes governing the levels of constitutive and inducible TNF-α and TNF RII might be an important risk factor, which could explain the variable outcomes of HBV infection.

Abstract
Cardiomyopathies (CMs) are primary disorders of cardiac muscle. They are a major cause of morbidity and mortality for all ages and, like acquired forms of cardiovascular disease, often result in heart failure. Molecular genetic studies have made remarkable progress in defining the pathogenesis of CM. The present study was the first report to evaluate the relationship between class II major histocompatibility complex (MHC) genes (HLA-DRB1 and HLA-DQB1) and the genetic susceptibility to primary dilated cardiomyopathy (DCM) in Tunisian patients. The human leukocyte antigen (HLA)-DRB1 and -DQB1 alleles were analyzed in 76 patients with primary DCM and 111 ethnically matched healthy controls using polymerase chain reaction-sequence specific primers technique. An increased frequencies of HLA-DRB1*0401 (OR = 2.67, P < 0.001), HLA-DQB1*0302 (OR = 3.28, P = 0.001) and HLA-DQB1*0401 (OR = 6.26, P = 0.005) alleles were found in the patients with primary DCM compared with healthy controls. Individuals with HLA-DRB1*1301 (OR = 0.24, P < 0.001) and HLA-DQB1*0201 (OR = 0.49, P = 0.002) alleles have a protective effect against primary DCM. Two haplotypes were associated with increased risk of primary DCM: DRB1*0401/DQB1*0302 (OR = 4.53, P = 0.002) and DRB1*0401/DQB1*0401 (OR = 9.42, P = 0.004). In conclusion, our data suggest that the variation in class II HLA alleles could be a genetic factor involved in the susceptibility to primary DCM in the Tunisian population.

Abstract
BACKGROUND Anaphylactic reactions during anesthesia are mainly the result of muscle-relaxant (MR) drugs. Skin tests, serologic detection of specific IgE, and in vitro leukocyte histamine release are used to investigate MR allergy. OBJECTIVE We describe a new assay that is based on the detection by flow cytometry of the altered expression of plasma membrane molecules of MR-activated basophils. METHODS For this assay, which we have named the BASIC assay, basophils are incubated in vitro with MR, after which they are fixed and then triple labeled with fluorescein-conjugated anti-CD63, tandem dye R-phycoerythrin-cyanin 5.1 conjugated anti-CD45, and R-phycoerythrin conjugated anti-IgE. The resulting B asophils' A ltered S urface I mmunofluorescence is detected by flow C ytometry (BASIC). RESULTS Forty-one patients who had an allergic reaction during general anesthesia and 23 control subjects without such a history were studied. All included subjects' basophils were tested in the BASIC assay with at least 4 MR: suxamethonium, gallamine, vecuronium, and pancuronium. After reaction of the basophils of the MR-allergic patients with MRs, increased surface expression of CD63 and CD45 and decreased expression of IgE were detected. Increased expression of CD63 was observed most frequently and it was stronger than the alteration of the 2 other markers. Cross-reactivity between MRs commonly occurred. MRs diluted 10(-1) activate the basophils of the control subjects, suggesting that at relatively high concentrations MRs are also nonspecific basophil activators. CONCLUSION In the diagnosis of MR allergy, the BASIC assay has a good specificity but a low sensitivity, and it correlates strongly with skin test results. It is currently appraised for the diagnosis of anaphylactic reaction induced by other classes of drugs.

Abstract
Antiphospholipid antibodies were investigated in 37 individuals with sickle cell disease and compared to a control group of 30 healthy subjects. Sickle cell patients included 18 homozygous sickle cell patients, 8 S/beta thalassemic patients and 11 sickle cell trait subjects. In all individuals, antiphospholipid antibodies were explored by lupus anticoagulant (LA) detection and the quantification of IgG and IgM anticardiolipin (aCL) isotypes, total antiphospholipid antibodies (APA) and IgM, IgG and IgA antiphospholipid classes. In homozygous sickle cell patients, mean level of IgG aCL and total APA were significantly increased (17.02 +/- 8.88 GPL/ml, p < 0.05 and 10.64 +/- 10.58 UPL/ml, p < 0.05 respectively). The IgG aCL, total APA and LA frequencies were 22.2%, 44.4% and 62.2%, respectively. APA isotypes were mostly IgG or IgG and IgA. In S/beta thalassemic patients, mean levels of APA were significantly increased (10.81 +/- 7.82 UPL/ml, p< 0.05). Their frequency was 71.4% and they were mostly IgG or IgG and IgA. In patients with sickle cell trait, mean levels of APA were significantly increased (10.84 +/- 5.84 UPL/ml, p < 0.01). Their frequency was 72.7% and mostly of IgG isotype. Our study showed a close association between high APA levels and sickle cell syndrome, however there was no relationship between high levels of antiphospholipid antibodies and the major complications of sickle cell disease.

Abstract
The aim of this in vitro study was to sketch the subtle anticoagulant profile of iopamidol 300 mg l/ml (low osmolality non ionic contrast medium) and meglumine amidotrizoate 370 mg l/ml (high osmolality ionic contrast medium) in situations where variable amounts of clotting factors are observed and to check whether thrombin-generation significantly occurred in non anticoagulated blood-contrast materials mixtures. In the first experiment, mixtures of deficient plasmas with a routine plasma pool provided different ranges with variable amounts of clotting factors II, V, VIII, X, XI and XII. For each clotting factor level studied within these ranges, an activated partial thromboplastin time was determined with either contrast material loaded thromboplastin (5% v/v) or glucose loaded thromboplastin (5% v/v) used as a control. In the second experiment fibrino-peptide A (FpA) or modified antithrombin III (ATM) assays were performed in either (9:1) non anti-coagulated blood contrast materials mixtures or blood-glucose mixtures (control). Differing aPTT prolongation profiles were observed when clotting factors V, VIII, XI and XII were lowered in the plasma. However, neither iopamidol nor amidotrizoate induced an aPTT prolongation with decreasing clotting factor II. In the second experiment no significant thrombin generation was observed as both blood-contrast materials mixtures showed significantly lower FpA and ATM levels (p < 0.001) than glucose control after 5 minutes and 10 minutes incubation at room temperature. These findings provide evidence that the use of iopamidol in angiographic procedures does not increase risk of clotting or hemorrhage.

Abstract
The fibrinolytic potential was evaluated in 37 patients with homozygous sickle cell disease and compared to a control group of 30 age- and sex-matched healthy volunteers. In all individuals, the euglobulin clot lysis time and plasma antigen levels of t-Pa and PAI-1 were measured before and after venous occlusion (v.o) for 10 min. The global fibrinolytic activity was normal in 4 patients (good responders to v.o), while it was decreased in 33 patients (poor responders to v.o). Among the latter, 22 patients had significantly increased baseline levels of PAI-1 Ag (82.6 +/- 27.5 ng/ml, p < 0.001) and a normal release of t-Pa Ag after v.o. In contrast, 11 patients had basal values of PAI-1 Ag comparable to those in controls with a defective release of t-Pa Ag after v.o (11.4 +/- 5.2 ng/ml, p < 0.01). These data provide evidence for reduced fibrinolytic capacity resulting from either increased basal levels of PAI-1 or defective release of t-PA.
