Abstract
Neurological manifestations of novel coronavirus disease (COVID-19) are reported to occur in as much as 37% of the affected patients. These manifestations range from headache and dizziness to altered mental status and consciousness, anosmia, ageusia, sensory disturbances, and stroke. The mechanisms by which the neurological symptoms arise are not yet determined but may either proceed as an indirect consequence of systemic hyperinflammation or result from the direct invasion of the virus to neural and glial cells. The neural invasion can explain both the retrograde pathway of encephalitis and the early manifestation of anosmia by invading the olfactory bulb. Moreover, in the case of attacking the brain stem, it may take part in the early apnea manifestation reported by patients. Additionally, neurotropism of the virus could be the cause of acute hemorrhagic encephalitis. Hyperinflammation can have acute and prolonged effects in the nervous system, such as acute demyelination and predisposition to multiple sclerosis. Moreover, the pro-inflammatory state contributes to hypercoagulation, which in turn could result in cerebrovascular injuries in COVID-19 patients. This chapter would discuss that the neurologic manifestations of the COVID-19 are to be looked at as a multifactorial entangled phenomenon.

Abstract
BACKGROUND AND AIMS Autoimmune hepatitis is a chronic immune-mediated liver injury caused by dysregulated immune response to liver antigens. Genetic susceptibility is affected by multiple single nucleotide polymorphisms in immune-related genes. There are few reports on the association of TGF-β and IL-10 genetic variants with autoimmune hepatitis. METHODS Allele frequency and genotype status of IL-10 -1082, -819, -592 and TGF-β +869 and +915 polymorphisms were investigated in 57 unrelated patients with autoimmune hepatitis and 140 healthy controls by polymerase chain reaction with sequence-specific primers. RESULTS IL-10 -592 and -819 allele frequencies and genotypes were not associated with autoimmune hepatitis in our population, while IL-10 -1082 genotypes were. IL-10 -1082/-819/-592 "high-producing" haplotype GCC was significantly less frequent in patients. TGF-β +869 "high-producing" allele C and genotype CC were significantly more in autoimmune hepatitis, compared to controls; whereas, TGF-β +915 "low-producing" allele C and genotype CC were significantly more in autoimmune hepatitis compared to control. TGF-β +869/+915 haplotype TG was significantly less frequent in patients while CC haplotype was significantly more frequently observed in patients. CONCLUSION We identified a significant association between IL-10 -1082/-819 and TGF-β +869/+915 genotypes and haplotypes with autoimmune hepatitis in Iranians.

Abstract
OBJECTIVES To correlate total and lobar liver and spleen volume with disease severity in primary sclerosing cholangitis (PSC) as determined by Mayo risk score. METHODS This HIPAA-compliant single center retrospective study included 147 PSC patients with available imaging studies (MRCP/CT) and laboratory data between January 2003 and January 2018. Total and lobar (right, left and caudate) liver volume and spleen volume were measured. ANOVA test was performed to assess the differences in volumes between low, intermediate and high-risk groups (Mayo risk score <0, >0 and <2, >2, respectively). Correlations between volumes and Mayo risk score were calculated. ROC analysis was performed to assess the accuracy of the variable with the strongest correlation to PSC severity to predict Mayo risk score. P value <0.05 was considered statistically significant. RESULTS The mean age of this cohort was 45 ± 17 years; 58% were men. Absolute volumes of left lobe, caudate and spleen and volume ratios of left lobe and caudate to total liver volume of the high-risk group were significantly higher compared to those of low and intermediate risk groups (p < 0.05). Left lobe to total liver volume ratio had the highest correlation to Mayo risk score (Pearson correlation coefficient 0.61, p < 0.05) and on ROC analysis it had 84.4% accuracy in detecting high-risk PSC. CONCLUSIONS In this single institution large cohort study, the left lobe to total liver volume ratio was the best quantifiable volumetric biomarker to correlate with severity of PSC as identified by Mayo risk score.

Abstract
AIM To analyse the change in size on follow-up of hepatic adenomas (HAs) and adenomatosis, and to investigate the relationship of imaging features with size change. MATERIALS AND METHODS The study included 44 patients (142 lesions) who underwent magnetic resonance imaging (MRI) or computed tomography (CT) for diagnosis and follow-up of HA. The imaging features and percentage change in maximum tumour dimension were observed over a follow-up duration of up to 139 months. RESULTS With an average follow-up of 43 months, 37% lesions decreased in size, 58% were stable, 4% increased; one lesion regressed completely. Adenomas were stratified into size groups (<3, 3-5, and ≥5 cm). Size change among the three groups was similar (p>0.05). Percent size change was different for lesions followed for ≤12 months (-7.2%) compared with lesions followed for 13-60 months (-20.5%), and those followed for ≥60 months (-23.5%; p<0.05); there was no difference between lesions followed for 13-60 months and ≥60 months (p=0.523). Baseline size and percent size change was similar between the hepatocyte nuclear factor 1α-inactivated HA (HA-H) and inflammatory HA (HA-I) subtype (p>0.05). CONCLUSION Most adenomas were either stable or regressed on follow-up. Size change was independent of baseline size. After an initial size decrease within 5 years, no further size reduction was noted on extended follow-up. The percent size change in the HA-H and HA-I subtype was similar.

Abstract
BACKGROUND AND PURPOSE The Centers for Medicare and Medicaid Services imposed a 25% professional component multiple procedure payment reduction for the professional component of advanced diagnostic imaging modalities in January 2012. In 2017, the Centers for Medicare and Medicaid Services rolled back the multiple procedure payment reduction to 5% for subsequent imaging. To evaluate the effect of this change, we analyzed 5 months of Centers for Medicare and Medicaid Services procedures at Johns Hopkins Medical Institution. MATERIALS AND METHODS We analyzed the procedure codes and reimbursement rate for studies performed between January 1 and May 31, 2017. Patients with Medicare insurance who had multiple diagnostic procedures in a day were selected. Per the Centers for Medicare and Medicaid Services guidelines, procedures with the highest price were considered fully reimbursed and subsequent studies were marked for differences between 25% (2013-2016) and 5% reduction (2017). RESULTS We included 8787 patients with 22,236 procedures (mean, 2.53 studies/day). CT, MR imaging, and ultrasound scans composed 75.9%, 21.5%, and 2.6% of all studies, with 61.2%, 54.9%, and 85.4% of the procedures of each technique subject to multiple procedure payment reduction, respectively. The projected reimbursement for these studies was $1,666,437, which translated to a $179,782 (12.1%) increase in revenue comparing 25%-versus-5% multiple procedure payment reduction rates for 5 months: $128,542 for CT, $47,802 for MR imaging, and $3439 for ultrasound. The annual overall prorated increase in revenue would be $431,476. The impact was maximal for neuroradiology. CONCLUSIONS With the recent favorable adjustment in multiple procedure payment reduction regulations, CT-heavy subspecialties like neuroradiology benefit the most with revenue increases. Different practice settings might experience revenue increases to a different extent, depending on the procedure and payer mix.

Abstract
Interferon regulatory factor 5 (IRF5) is a member of IRF family which induce signaling pathways and are involved in modulation of cell growth, differentiation, apoptosis, and immune system activity. Juvenile idiopathic arthritis (JIA) is an auto-inflammatory syndrome where the inflammatory markers are believed to play a fundamental role in its pathogenesis. In this study, we aimed to assess the association of IRF5 gene polymorphisms with susceptibility of JIA in Iranian population. Three IRF5 single-nucleotide polymorphisms (rs10954213 A/G, rs2004640 G/T, and rs3807306 G/T) were genotyped using TaqMan assays in 55 patients with JIA and 63 matched healthy individuals. The frequency of the IRF5 rs2004640 T allele was significantly higher (69 vs 45%, P value = 0.0013) in JIA group as compared to control. The frequency of the IRF5 rs 2004640 G allele was significantly higher in the control group in comparison to JIA group (54 vs 32%, P value = 0.001). Allele and genotype frequencies of the rs10954213 and rs3807306 did not show any significant difference between JIA and control group. IRF5 rs 2004640 T allele can be considered as a risk factor for the development of JIA and presence of rs 2004640 G may be act as protective factor.

Abstract
OBJECTIVE To investigate whether volumetric enhancement on baseline MRI and volumetric oil deposition on unenhanced CT would predict HCC necrosis and response post-TACE. METHOD Of 115 retrospective HCC patients (173 lesions) who underwent cTACE, a subset of 53 HCC patients underwent liver transplant (LT). Semiautomatic volumetric segmentation of target lesions was performed on dual imaging to assess the accuracy of predicting tumour necrosis after TACE in the whole cohort and at pathology in the LT group. Predicted percentage tumour necrosis is defined as 100 % - (%baseline MRI enhancement - %CT oil deposition). RESULTS Mean predicted tumour necrosis by dual imaging modalities was 61.5 % ± 31.6%; mean percentage tumour necrosis on follow-up MRI was 63.8 % ± 31.5 %. In the LT group, mean predicted tumour necrosis by dual imaging modalities was 77.6 % ± 27.2 %; mean percentage necrosis at pathology was 78.7 % ± 31.5 %. There was a strong significant correlation between predicted tumour necrosis and volumetric necrosis on MRI follow-up (r = 0.889, p<0.001) and between predicted tumour necrosis and pathological necrosis (r = 0.871, p<0.001). CONCLUSION Volumetric pre-TACE enhancement on MRI and post-TACE oil deposition in CT may accurately predict necrosis in treated HCC lesions. KEY POINTS • Imaging-based tumour response can assist in therapeutic decisions. • Lipiodol retention as carrier agent in cTACE is a tumour necrosis biomarker. • Predicting tumour necrosis with dual imaging potentially obviates immediate post-treatment MRI. • Predicting tumour necrosis would facilitate further therapeutic decisions in HCC post-cTACE. • Pre-TACE MRI and post-TACE CT predict necrosis in treated HCC.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a chronic long-lasting hepatocellular inflammation associated with circulating auto antibodies. In addition to the genetic component, several cytokines have been implicated to be involved in AIH. This study was performed to investigate potential associations of AIH with IL4 gene variants. METHOD The studied alleles and genotypes included: IL4G/T allele polymorphisms at position -1098 and C/T allele polymorphisms at two positions (-33 and -590) on the IL4 gene, in addition to the A/G allele polymorphisms at position +1902 on the IL4RA gene. RESULT The IL4 C allele and CC genotype at position -590 and TT genotype at position -33 had a significantly higher frequency in AIH patients. CONCLUSION This study identified the IL4 C allele and CC genotype susceptibility gene in AIH, which will provide better insights into the mechanisms of AIH and potential therapeutic interventions.

Abstract
Multiple sclerosis (MS) is a multifaceted disease in which genetic and environmental factors are involved. Although neurodegeneration aspect of MS has major influence in patients' disability, none of the available treatments have been shown to obviously reduce neurodegeneration. Recently, the role of Erythropoietin (EPO) as a neuroprotective and anti-inflammatory agent has been attracted tremendous interest. In the present randomized double-blind pilot study, we combined EPO with methylprednisolone (MPred) in severe motor relapsing-remitting MS (RR-MS) patients to target both inflammatory and neurodegenerative aspects of disease. Twenty patients with RR-MS in relapse phase were randomized into two groups. The case group (10 patients) received intravenous MPred (1,000 mg/24 h) and intravenous EPO (20,000 U/24 h) for five consecutive days, and the control group (10 patients) received just MPred at the same dose as the case group, and a placebo. Both groups were followed for 3 months by ambulatory index (AI), Expanded Disability Status Scale (EDSS) and by magnetic resonance imaging (MRI) parameters. Improvement in maximal distance walking, reflected by reduction in AI and EDSS, was observed in EPO group after second month and continued after 3 months. Furthermore, MRI data analysis showed significant reduction in the number of T2WI lesions in EPO group without any significant change in contrast enhancing and black hole lesions. There was no major side effect in EPO group. The results of this first therapeutic pilot trial in RR-MS patients are promising, but need to be validated in larger trials.

Abstract
BACKGROUND/OBJECTIVE Genetic factors seem to play an important role in the pathogenesis of ulcerative colitis (UC). Genome wide association studies showed a highly significant association between interleukin 23 receptor (IL23R) single nucleotide polymorphisms (SNPs) and Crohn's disease; however, there are contrary results regarding the disease-modifying effects of IL23R variants in UC. This study was performed in a group of patients with UC to test the possible role of IL23R SNPs in conferring susceptibility or protection against the disease. METHODS The study was performed on 67 Iranian adult patients with UC and 78 healthy controls. Eight IL23R SNPs were genotyped, using real-time polymerase chain reaction (RT-PCR). The frequencies of alleles and genotype at each position were determined and compared between two groups of patients and controls. RESULTS The frequency of the T allele at position rs1343151 was significantly higher in the patient group, compared to the controls (P=0.018). The TT genotype at the same position was also significantly overrepresented in the patient group (P=0.02). There was no significant difference in alleles and genotype frequencies of other SNPs between patients and controls. CONCLUSIONS This study identified a new susceptibility locus associated with UC. Our findings provide further insight into the genetics of UC, which might be amenable to future therapeutic intervention.

Abstract
Common variable immunodeficiency (CVID) is characterized by low levels of circulating immunoglobulins and compromised specific antibody response leading to frequent infections. Cytokines play an important role in the orchestration of the antibody response. Several previous studies have attempted to identify distinct cytokines responsible for the inflammatory changes and different manifestations of CVID, but there are conflicting results regarding the cytokine profiles in CVID patients. In light of this, an extensive review regarding the level of various cytokines and their potential therapeutic role in CVID patients was performed. This review delineates the contribution of interleukin (IL)-1, IL-2, IL-4, IL-5, IL-6, IL-7, IL-10, IL-12, IL-21, interferons, tumor necrosis factor (TNF)-α, IL-17, APRIL (a proliferation inducing ligand) and BAFF (B cell activating factor) in CVID disease and outline their potential therapeutic implications in these patients.

Abstract
AIM Multiple sclerosis (MS) is an inflammatory neurodegenerative disorder that inflammatory cytokines have been implicated in its immunopathogenesis. Resistin, a member of cysteine-rich secretory proteins family, identified with inflammatory properties in humans. To elucidate whether different genotypes of resistin are involved in MS pathogenesis, we compared serum levels of TNF-α, IL-1β, hs-CRP, and resistin levels in different genotypes of MS patients with relapsing remitting type and healthy subjects. METHODS IN a case-control study, 86 MS patients and 86 age- and sex-matched healthy subjects were enrolled. The age, gender distribution, and BMI of MS patientsand control group were similar. The serum levels of TNF-α, IL-1β, and Resistin were measured by ELISA. hs-CRP was measured by imunoturbidimetric method. After DNA extraction, the analysis of -420C/G SNP (rs1862513) was performed via PCR-RFLP method. RESULTS The resistin, TNF-α, IL1β, and hs-CRP levels were significantly higher in MS patients compared with control group. The distribution of "rs1862513" genotypes were not significant between MS and control groups. Although resistin and TNFα levels were higher in GG genotype carriers of both groups, but the difference was significant only in MS patient. CONCLUSION Resistin gene polymorphisms may modify the being susceptible to MS disease, which may cause through various levels of cytokines between genotypes.

Abstract
Longevity is a multifaceted trait in which variety of genes and environmental factors are involved. Newly, the role of vitamin D has been revived regarding its potential advantage on delaying the aging process. Vitamin D exerts its effect through vitamin D receptor (VDR). VDR-FokI is the only polymorphism which alters the VDR length. We examined the frequency of FokI genotypes in old age population as compared to young adults to determine the discerning genotype of FokI polymorphism leading to longer living. In addition, to highlight the position of FokІ polymorphism in quality of life; a cognitive function assessment was performed. 728 participants participated in this study of which 166 individuals were elderly residents of Kahrizak Charity Foundation. The rest were participants of Iranian Multicenter Osteoporosis Study (IMOS). Genomic DNA was extracted from peripheral blood and VDR genotype was detected by the polymerase chain reaction. The participants in the elderly group underwent a cognitive function assessment. Cognitive function was measured with the mini mental state examination (MMSE). Data were analyzed by SPSS 16.5. The prevalence of ff genotype showed 48% decrease in elderly population as compared to young adults (P=0.06). In addition, F allele was over-represented in the elderly group as compared to controls (P=0.05). Also, "FF" participants of elderly group had higher MMSE as compared to "ff" genotype (18.16Vs17.12). Our data suggest that single nucleotide polymorphisms (SNPs) in FokI may be possibly involved in longevity and cognitive function.
