Abstract
OBJECTIVE Dentinogenesis imperfecta (DI) is an inherited dentin defect and may be isolated or associated with disorders such as osteogenesis imperfecta, odontochondrodysplasia Ehler-Danlos and others. Isolated DI is caused mainly by pathogenic variants in DSPP gene and around 50 different variants have been described in this gene. Herein, we report on 19 patients from two unrelated Egyptian families with isolated DI. Additionally, we focused on genetic counselling of the two families. MATERIALS AND METHODS The patients were examined clinically and dentally. Panoramic X-rays were done to some patients. Whole exome sequencing (WES) and Sanger sequencing were used. RESULTS WES revealed two new nonsense variants in DSPP gene, c.288T > A (p.Tyr96Ter) and c.255G > A (p.Trp85Ter). Segregation analysis by Sanger sequencing confirmed the presence of the first variant in all affected members of Family 1 while the second variant was confirmed to be de novo in the patient of Family 2. CONCLUSIONS AND CLINICAL RELEVANCE Our study extends the number of DSPP pathogenic variants and strengthens the fact that DSPP is the most common DI causative gene irrespective of patients' ethnicity. In addition, we provide insights on genetic counseling issues in patients with inherited DSPP variants taking into consideration the variable religion, culture and laws in our society.

Abstract
BACKGROUND Chronic total occlusion (CTO) lesions in coronary arteries pose a significant challenge for coronary interventionists, often leading to referrals for coronary artery bypass graft surgery (CABG). Successful percutaneous coronary intervention (PCI) for CTOs requires accurate assessment of procedural potential. This study, comprising 100 Egyptian patients aged 37-81, compares the predictive efficacy of various CTO scoring systems in PCI success determination. Patients with CTO in at least one coronary artery, planned for elective PCI based on objective evidence of ischemia, were included. Experienced operators performed PCI, recording procedural variables, and assessing complications. Logistic regression analysis revealed an inverse linear relationship between success rates and score values across all systems. RESULTS Although, the predictive capacity of the scores was similar, with slight differences. The Euro CTO (CASTLE) score10 exhibited superior predictive efficacy, followed by the CL score9, while PROGRESS8 and J-CTO7 scores showed lower significance. ORA CTO11 score demonstrated intermediate predictive ability, and PROGRESS score8 had the least predictive value. CONCLUSION The CASTLE score10 proved most effective in predicting PCI success for CTO cases in Egyptian patients, with operators advised to choose scoring systems based on experience and case characteristics. Proper planning remains crucial for optimizing success rates in CTO PCI procedures, irrespective of the scoring system employed.

Abstract
OBJECTIVES describing the clinical features of twelve Egyptian patients with Papillon-Lefever syndrome (PLS). Five novel mutations in the cathepsin C (CTSC) gene are introduced and the phenotype of the syndrome is expanded by the identification of new clinical features. DESIGN the clinical, oro-dental data of twelve Egyptian patients from seven unrelated families are described. Sequence analysis of the CTSC gene was performed to identify the causative mutaions. RESULTS Typical PLS features were presented in all patints but with variable severity. One patient showed atypical dental features including dental structural defect, minimal periodontitis, severe gingivitis, and delayed closure of root apices. Another patient presented with arachnodactyly, dystrophic nails, and buphthalmos in the right eye secondary to uncontrolled congenital glaucoma. Mutational analysis of CTSC gene revealed seven distinct homozygous variants including five novel ones: c.285_286delGT (p.Leu96GlufsTer2), c .302 G>C (p.Trp101Ser), c.622_628delCACAGTC (p.H208Efs*11), c.1331delinsAAAAA (p.G444Efs*4) and c .1343 G>A (p.Cys448Tyr). The previously reported missense variant c .757 G>A (p.Ala253Thr) was found in one patient. This variant is very close to the splice region and by functional studies, we proved that it results in exon skipping and early protein truncation (p.R214Sfs*46). CONCLUSION We report five novel CTSC variants and describe rare and unusual associated clinical and dental findings such as dental structural defects, delayed closure of root apices, and congenital glaucoma. Therefore, our results expand both the phenotypic and mutational spectrum of PLS.

Abstract
BACKGROUNDS A worldwide coronavirus pandemic has affected many healthcare systems in 2019 (COVID-19). Following viral activation, cytokines and chemokines are released, causing inflammation and tissue death, particularly in the lungs, resulting in severe COVID-19 symptoms such as pneumonia and ARDS. COVID-19 induces the release of several chemokines and cytokines in different organs, such as the cardiovascular system and lungs. RESEARCH IDEA COVID-19 and its more severe effects, such as an elevated risk of death, are more common in patients with metabolic syndrome and the elderly. Cytokine storm and COVID-19 severity may be mitigated by immunomodulation targeting NF-κB activation in conjunction with TNF- α -inhibition. In severe cases of COVID-19, inhibiting the NF-κB/TNF- α, the pathway may be employed as a therapeutic option. MATERIAL AND METHODS The study will elaborate on the Egyptian pattern for COVID-19 patients in the first part of our study. An Egyptian patient with COVID-19 inflammatory profiling will be discussed in the second part of this article using approved marine drugs selected to inhabit the significant inflammatory signals. A biomarker profiling study is currently being performed on Egyptian patients with SARS-COV-2. According to the severity of the infection, participants were divided into four groups. The First Group was non-infected with SARS-CoV-2 (Control, n = 16), the Second Group was non-intensive care patients (non-ICU, n = 16), the Third Group was intensive care patients (ICU, n = 16), and the Fourth Group was ICU with endotracheal intubation (ICU + EI, n = 16). To investigate COVID-19 inflammatory biomarkers for Egyptian patients, several inflammatory, oxidative, antioxidant, and anti-inflammatory biomarkers were measured. The following are examples of blood tests: CRP, Ferritin, D-dimer, TNF-α, IL-8, IL-6., IL-Ib, CD8, NF-κB, MDA, and total antioxidants. RESULTS AND DISCUSSION The results of the current study revealed many logical findings, such as the elevation of CRP, Ferritin, D-dimer, TNF- α, CD8, IL-6, IL-, NF-κB, and MDA. Where a significant increase showed in ICU group results (23.05 ± 0.30, 2.35 ± 0.86, 433.4 ± 159.3, 26.67 ± 3.51, 7.52 ± 1.48, 7.49 ± 1.04, 5.76 ± 1.31, 7.41 ± 0.73) respectively, and also ICU group results (54.75 ± 3.44, 0.65 ± 0.13, 460.2 ± 121.42, 27.43 ± 2.52, 8.63 ± 2.68, 10.65 ± 2.75, 5.93 ± 1.4, 10.64 ± 0.86) respectively, as well as ICU + EI group results (117.63 ± 11.89, 1.22 ± 0.65, 918.8 ± 159.27, 26.68 ± 2.00, 6.68 ± 1.08, 11.68 ± 6.16, 6.23 ± 0.07, 22.41 ± 1.39),respectively.The elevation in laboratory biomarkers of cytokines storm in three infected groups with remarkable increases in the ICU + EI group was due to the elevation of oxidative stress and inflammatory storm molecules, which lead to highly inflammatory responses, specifically in severe patients of COVID-19. Another approach to be used in the current study is investigating new computational drug compounds for SARS-COV-2 protective agents from the marine environment. The results revealed that (Imatinib and Indinavir) had the highest affinity toward Inflammatory molecules and COVID-19 proteins (PDB ID: -7CZ4 and 7KJR), which may be used in the future as possible COVID-19 drug candidates. CONCLUSION The investigated inflammatory biomarkers in Egyptian COVID-19 patients showed a strong correlation between IL6, TNF-α, NF-κB, CRB, DHL, and ferritin as COVID-19 biomarkers and determined the severity of the infection. Also, the oxidative /antioxidant showed good biomarkers for infection recovery and progression of the patients.

Abstract
OBJECTIVE To study the prevalence and impact of comorbidities among a cohort of patients with systemic lupus erythematosus (SLE). METHODS This study is retrospective, multicenter including 902 Egyptian patients with SLE. Medical records were reviewed for demographic data, clinical characteristics, routine laboratory findings, immunological profile, and medications. Moreover, SLE Disease Activity Index (SLEDAI), and the Systemic Lupus International Collaborating Clinics/American College Rheumatology Damage Index scores were calculated. RESULTS Comorbidities were found in 75.5% of the studied group with hypertension and dyslipidemia as the most frequent comorbidities (43.1% and 40.1%, respectively), followed by sicca features, avascular necrosis, diabetes, osteoporosis and renal failure (11.5%,9%, 9%,8.9%, and 7.1%, respectively). Multivariate regression model showed statistically significant relation between the presence of comorbid condition and each of age (P = 0.006), disease duration (P = 0.041), SLEDAI at onset (P < 0.001), cyclophosphamide intake (P = 0.001), and cumulative pulse intravenous methylprednisone (P < 0.001). Also, when adjusted to age and sex, those with multiple comorbid conditions had 18.5 increased odds of mortality compared to those without comorbidities (odds ratio (OR), 95% confidence interval (CI) = 18.5 (6.65-51.69)]. CONCLUSION Patients with SLE suffer from several comorbidities, with an increasing risk with age, longer disease duration, higher SLEDAI at onset, cyclophosphamide intake and cumulative pulse intravenous methylprednisone. Risk of mortality is exponentiated with multiple comorbidities.

Abstract
Progressive pseudorheumatoid dysplasia (PPRD), a rare autosomal recessive syndrome, is a type of skeletal dysplasia associated with pain, stiffness, swelling of multiple joints, and the absence of destructive changes. PPRD occurs due to loss of function pathogenic variants in WISP3 (CCN6) gene, located on chromosome 6q22. In this study, 23 unrelated Egyptian PPRD patients were clinically diagnosed based on medical history, physical and radiological examinations, and laboratory investigations. Sequencing of the whole WISP3 (CCN6) exons and introns boundaries was carried out for all patients. A total of 11 different sequence variations were identified in the WISP3 (CCN6) gene, five of them were new pathogenic variants: the NM_003880.3: c.80T>A (p.L27*), c.161delG (p.C54fs*12), c.737T>C (p.Leu246Pro), c.347-1G>A (IVS3-1G>A), and c.376C>T (p.Q126*). The results of this study expand the spectrum of WISP3 (CCN6) pathogenic variants associated with PPRD. Clinical and genetic analysis is important for proper genetic counseling to curb this rare disorder in the families.

Abstract
Objectives The study aimed to examine the frequency, causes, and predictors of mortality in a cohort of Egyptian systemic lupus erythematosus (SLE) patients and compare mortality causes and the survival rate in our cohort to African, Arabic, and Mediterranean studies. Patients and methods In this retrospective study, a review of medical records of 563 SLE patients (516 females, 47 males; median of age: 32 [IQR: 26-38 years]; range, 14 to 63 years) fulfilling the 1997 American College of Rheumatology (ACR) criteria between January 2015 and December 2019 was done. The data extracted included demographic, clinical, and laboratory features, treatments used, disease activity as measured by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), and damage index as measured by Systemic Lupus International Collaborating Clinics (SLICC) damage index. Causes of mortality were also reported. Results Out of 563 reviewed medical records, 50 (8.9%) patients died. Infection (28%) and organ damage (18%) were the most commonly reported causes of death. Multivariate Cox regression analysis showed that patients with cardiac manifestations, renal failure, those receiving higher doses of either oral (in their last visit) or intravenous (higher cumulative pulse steroids) steroids were at increased risk of mortality (p=0.011, p<0.001, p=0.01, and p<0.001, respectively; 95% confidence intervals 7.2, 63.9, 1.2, and 1.09, respectively). The overall survival at 5, 10, 15, and 20 years was 96.6%, 93.3%, 91.0%, and 83.2%, respectively, and 56.2% at 25 years until the end of the follow-up. Conclusion Cardiac manifestations, renal failure, and higher steroid doses were independent predictors of mortality in our cohort. As in most African countries, infection was the main cause of death in our study; however, the mortality rate and the five-year survival among our cohort were better than in African (sub-Saharan) countries and similar to Arabic and Mediterranean countries.

Abstract
Early childhood obesity is a real public health problem worldwide. Identifying the etiologies, especially treatable and preventable causes, can direct health professionals toward proper management. Measurement of serum leptin levels is helpful in the diagnosis of congenital leptin and leptin receptor deficiencies which are considered important rare causes of early childhood obesity. The main aim of this study was to investigate the frequency of LEP, LEPR, and MC4R gene variants among a cohort of Egyptian patients with severe early onset obesity. The current cross-sectional study included 30 children who developed obesity during the first year of life with BMI > 2SD (for age and sex). The studied patients were subjected to full medical history taking, anthropometric measurements, serum leptin and insulin assays, and genetic testing of LEP, LEPR and MC4R. Disease causing variants in LEP and LEPR were identified in 10/30 patients with a detection rate of 30%. Eight different homozygous variants (two pathogenic, three likely pathogenic, and three variants of uncertain significant) were identified in the two genes, including six previously unreported LEPR variants. Of them, a new frameshift variant in LEPR gene (c.1045delT, p.S349Lfs*22) was recurrent in two unrelated families and seems to have a founder effect in our population. In conclusion, we reported ten new patients with leptin and leptin receptor deficiencies and identified six novel LEPR variants expanding the mutational spectrum of this rare disorder. Furthermore, the diagnosis of these patients helped us in genetic counseling and patients' managements specially with the availability of drugs for LEP and LEPR deficiencies.

Abstract
BACKGROUND This study was performed to investigate the expression of different biomarkers in patients with hepatocellular carcinoma and its connection with detective biomarkers. To achieve this objective, seventy subjects were examined in this study, sub-grouped to forty HCC patients and thirty HCV-affected patients with matched thirty healthy individuals. The study involved several groups of participants who were matched based on their age and gender. METHODS The expression pattern of biomarkers was monitored by quantitative polymerase chain reaction (qRT-PCR). Finally, we utilized a ROC curve to investigate the predictive accurateness of those distinct biomarkers as well as a traditional tumor marker, AFP, in detecting HCC cases. RESULTS The baseline biomarker expression levels were markedly greater in HCC patients than in those affected by HCV or healthy subjects. We stated that the sensitivity and the specificity of the different biomarkers alone did not improve than that of AFP alone. When comparing AFP with different biomarkers, the diagnostic validity improves only when combining with CK-1. CONCLUSIONS Overall, our results indicate that CK-1 mRNA expression could help as a noninvasive tumor biomarker for HCC prognosis and diagnosis when combining with AFP.

Abstract
BACKGROUND Patients with bipolar disorder (BD) had contributed immensely to high health service utilization. Variation in clinical practices that miss to follow the standard guidelines all with the disorder complexity, deepened the management gap. This study aimed to provide an Egyptian epidemiological database of the ongoing clinical practices that framed different diagnostic and management choices in a sample of patients with bipolar disorder. Highlighting challenges and the need for optimized clinical practices. METHODS Over 4 months in 2014, 20 clinicians filled in a designed sheet of their routine healthcare practice with information about; caseload /month, management guidelines knowledge background. Out of 301 patients in acute episode BD, 300 patients aged 20 to 60 years from both sexes, completed their assessment using; (1) a semi-structured interview sheet, (2) Structured Clinical Interview for DSM-IV Axis I (SCID I) for psychiatric diagnoses, (3) Global Assessment of Functioning scale for illness impact. RESULTS Psychiatrists received 49.5 ± 37.0 (mean ± SD) patient /month. 95% of them reported positive knowledge background on BD diagnostic guidelines and treatment recommendations (G/R), 89.6% of patients had different initial diagnosis than BD.The most commonly given initial diagnosis was major depressive disorder (33%) followed by brief psychotic disorder(20.7%) and others. The median of time taken from the initial to bipolar diagnosis was 12.3 months. Majority of patients had evident functional impairment. Atypical antipsychotics were mostly used. Drug abuse and obesity were high comorbidities. CONCLUSION The evident gap in practice and BD complexity have negative impact on clinical outcomes. Physician's continuous medical education programs and individually tailored standard medical care are recommended for optimized practices.

Abstract
PURPOSE To study the relation between serum calprotectin level and acute noninfectious anterior uveitis in Egyptian patients. METHODS An observational prospective study carried out at Menoufia University Hospital during the period from March 2021 till June 2022, after informed consent from all studied patients. This study included 20 eyes of patients with Acute Anterior Uveitis (AAU) and 20 eyes healthy individuals matched sex and age as the control group. Full history taking, ophthalmological examination and serum calprotectin levels were performed for both patients and controls. RESULTS Serum calprotectin levels were substantially higher in patients' eyes with acute anterior uveitis than in healthy eyes (61.45±7.89 vs 32.50±11.64; 95% CI: 22.58-35.32; P < 0.001). ROC curve analysis showed that the cut-off point of serum calprotectin in severity detection of AAU was ≥58.0, with sensitivity of 95%, specificity of 43% at AUC of 0.986, with reached to significant level (p < 0.001). CONCLUSION Serum calprotectin levels were significantly elevated with positive previous uveitis and marked grade indicating a possible role of calprotectin in the pathogenesis of non-infectious AAU. The serum calprotectin cut-off points for severity detection of AAU were 58.0, with sensitivity of 95% and specificity of 43%. Finally, we identified serum calprotectin as a potential biomarker for detection of anterior uveitis severity and patients' morbidity risk. Further investigation with large sample size is needed to assess the relationship between calprotectin and uveitis activity.

Abstract
Introduction An inflammatory environment is the common pathway for the development of cholangiocarcinoma (CCA). The natural killer group 2D receptor (NKG2D), an activating receptor for NK cells, is a potent immune axis in the antitumor and antimicrobial immune response through its binding to NKG2D ligands (NKG2DLs). NKG2DLs are normally absent or poorly expressed in most cells; conversely, they are upregulated in stressed cells. We studied the rs2596542 polymorphism located upstream of the MICA gene, which encodes an NKG2DL, in patients with CCA as a marker for early disease detection and a possible therapeutic target. Material and methods A case-control study was conducted on 40 patients with CCA and 45 healthy individuals (as controls). After routine examination, the rs2596542 polymorphism of the MICA gene was investigated using real-time PCR. Results We found that a TT homozygous genotype was significantly predominant in patients with CCA (p = 0.039), with the T allele being dominantly distributed in CCA (p = 0.007). High levels of CA19-9 were significantly associated with the TT genotype in the patients. However, we did not detect significant differences in rs2596542C/T genotype and allele distribution between patients with CCA with cirrhosis and those without cirrhosis (p > 0.05). Conclusions The MICA rs2596542 polymorphism may affect the susceptibility to CCA, but not its progression. The TT genotype could be used as a potential diagnostic marker for CCA and triggering the MICA pathway could be a promising therapeutic target.

Abstract
UNLABELLED This study describes the clinical, radiological, and molecular data of four new patients with osteoporosis-pseudoglioma syndrome and assesses their response to bisphosphonate therapy. INTRODUCTION Osteoporosis-pseudoglioma syndrome (OPPG) is a very rare disorder characterized mainly by severe juvenile osteoporosis and congenital blindness. OPPG is caused by biallelic mutations in the gene encoding low-density lipoprotein receptor-related protein 5 (LRP5). METHODS We present the clinical, radiological, and molecular findings of four new patients with OPPG from Egypt. We also assessed patients' response to oral and intravenous bisphosphonate therapy. RESULTS All patients had reduced bone mineral density (BMD) with variable number of fractures per year, in addition to bone abnormalities and the characteristic eye phenotype associated with OPPG. Mutation analyses of LRP5 gene revealed three different homozygous variants including two novel ones, c.7delG (p.A3Qfs*80) and c.3280G > A (p.E1094K). The c.3280G > A (p.E1094K) was recurrent in two unrelated patients who shared a unique haplotype suggesting a possible founder effect. The use of bisphosphonate therapy was beneficial; however, intravenous bisphosphonate administration led to a more favorable response. CONCLUSION Our study described the phenotypic and genetic features of four patients with OPPG and identified two new LRP5 variants, thus expanding the mutational spectrum of OPPG. In addition, our study reinforces the efficiency of using intravenous bisphosphonates in the management of patients with OPPG.

Abstract
BACKGROUND AND PURPOSE Unverricht-Lundborg disease (ULD) is a common type of progressive myoclonic epilepsy (PME). It is caused mostly by biallelic dodecamer repeat expansions in the promoter region of CSTB gene. Despite highly prevalent in the Mediterranean countries, no studies have been reported from Egypt. This article study the presence of CSTB gene mutations among Egyptian patients clinically suspected with ULD, and describes the clinical and genetic characteristics of those with confirmed gene mutation. METHODS Medical records of patients following up in two specialized epilepsy clinics in Cairo, Egypt were retrospectively reviewed. Twenty patients who belonged to 13 unrelated families were provisionally diagnosed with ULD based on the clinical presentation. Genetic testing was done. Clinical characteristics, demographic data and EEG findings were documented. RESULTS Genetic studies confirmed the presence of the CSTB dodecamer repeat expansion in 14 patients from 8 families (frequency 70 %). The mean duration of the follow-up was 5 years. Male to female distribution was 1:1 with a mean age of onset 9.7 years. Consanguinity was noted in 4 families. Eight patients had their first seizure between the age of 10 and 20 years. Myoclonic jerks ranged in severity from mild in three unrelated patients to severe in one. Only 3 had cognitive impairment. CONCLUSION Our study confirms the presence of CSTB mutation among Egyptian patients suspected with ULD. There was no clear phenotype-genotype correlation among the studied group of patients. In addition, we noticed variable inter and intra familial severity among patients from the same family.

Abstract
Purpose The study aimed to detect the frequencies of allelic variants (TPMT*3A, TPMT*3C, and TPMT*3G) in the TPMT genes in the Egyptian population and assess the association between TPMT polymorphisms and azathioprine (AZA)—clinical efficacy and adverse drug reactions among Egyptian patients with autoimmune diseases. Patients and Methods Design A prospective, observational single-center clinical trial. Setting Rheumatology and Rehabilitation Department, Kasr Alainy University Hospital, Faculty of Medicine, Cairo University. Patients Patients attending Kasr Alainy Rheumatology Outpatient Clinic between December 1, 2017 and June 30, 2019 were included in the study after signing a consent form. TPMT genetic polymorphisms were detected for all patients, and the association between polymorphisms presence and azathioprine’s clinical efficacy and adverse drug reactions were determined. Results A total of 150 patients with a mean age of 35.85 years were enrolled in this study. About 72% of patients were heterozygous in the TPMT*3 G460A and TPMT*3 A719G mutant alleles and 81% were wild type in the TPMT*2 G238C mutant allele. Abnormal liver function tests were detected in 42% of patients. Myelosuppression was presented as anemia which was detected in 63% of patients, leucopenia in 51%, and thrombocytopenia in 25% of patients. AZA clinical failure has occurred in 50% of patients where AZA was discontinued or shifted to another drug which occurred in 45% of patients. Myelosuppression rates were higher in homozygous patients in the three mutant alleles, but statistically significant in TPMT*2 G238C while not statistically significant in TPMT*3 G460A and TPMT*3 A719G. Females had a higher risk of immunosuppression than males (p-value 0.031). Conclusion The study provided an overview of the genomic variations in the Egyptian population. Routine TPMT genotyping prior to the initiation of AZA therapy should be considered.

Abstract
Blepharophimosis-ptosis-intellectual disability syndrome (BPID) is an extremely rare recognizable blepharophimosis intellectual disability syndrome (BID). It is caused by biallelic variants in the UBE3B gene with only 24 patients described worldwide. Herein, we report on the clinical, brain imaging and molecular findings of additional nine patients from six unrelated Egyptian families. Patients presented with the characteristic features of the syndrome including blepharophimosis, ptosis, upslanted palpebral fissures with epicanthic folds, hypertelorism, long philtrum, high arched palate, micrognathia, microcephaly, and intellectual disability. Other findings were congenital heart disease (5 patients), talipes equinovarus (5 patients), genital anomalies (5 patients), autistic features (4 patients), cleft palate (2 patients), hearing loss (2 patients), and renal anomalies (1 patient). New or rarely reported findings were spherophakia, subvalvular aortic stenosis and hypoplastic nails, and terminal phalanges. Brain MRI, performed for 7 patients, showed hypogenesis or almost complete agenesis of corpus callosum. Genetic studies revealed five novel homozygous UBE3B variants. Of them, the c.1076G>A (p.W359*) was found in three patients from two unrelated families who shared similar haplotype suggesting a likely founder effect. Our results strengthen the clinical, dysmorphic, and brain imaging characteristic of this unique type of BID and extend the mutational spectrum associated with the disorder.

Abstract
Interleukin 17 (IL-17) is one of the pro-inflammatory cytokine. Psoriasin is a noticeably over-expressed protein found in the skin lesions of psoriatic patients. Our current study was planned to examine the association of (- 947 A/G) single nucleotide polymorphism (SNP) in IL-17RA promoter region (rs4819554) with psoriasis susceptibility in Egyptian psoriatic patients. Our study included 100 patients and 100, age as well as sex matched, control groups. IL-17RA SNP association was studied using allelic discrimination. RT-qPCR and ELISA were done to assess IL-17 expression. ELISA was performed to assess psoriasin expression. Our study showed a significant association between IL-17 rs4819554 SNP and psoriasis risk, evidenced by higher G allele and AG genotype frequencies in psoriatic patients when compared to controls (allelic: OR 2.283, 95% CI 1.321-3.946, p = 0.003, and genotype: OR 3.026, 95% CI 1.356-6.752, p = 0.007). Additionally, serum psoriasin level was significantly increased when comparing psoriatic patients to controls (p = 0.0003). Moreover, significant increase in IL 17 gene and protein level in AA, AG psoriatic genotypes compared to the corresponding genotypes in normal control (p = 0.0004). IL-17 rs4819554 is significantly associated with psoriasis, and with psoriasin level, in the Egyptian population.

Abstract
BACKGROUND Egypt is a densely populated country with living habits and health care services that differ from urban to rural regions. We aimed to study how characteristics of stroke vary among these regions. METHODS This is a cross-sectional observational study of ischemic stroke, thus hemorrhagic and venous strokes were excluded. A total of 1475 ischemic stroke patients were recruited for analysis from a tertiary hospital in Cairo representing urban area and from a secondary care hospital in Suhag representing rural region. RESULTS Analysis was done for 1143 ischemic stroke patients from urban and 332 from rural area. Onset to door was shorter in urban. Urban patients showed an older age and higher prevalence of hypertension and diabetes (65.9%, 48.6% respectively), while rural patients were characterized by female preponderance (51.5%), more dyslipidemia, smoking 44.6%, stroke in young 20.5%, atrial fibrillation 23.8% % and recurrent stroke 44.3%. Rural cases showed a severer deficit at onset and poorer outcome. CONCLUSION Vascular risk factors, stroke type, and presentation tend to differ in Egypt according to the geographic distribution whether urban or rural. Studying patterns of such difference may aid in planning specific targeted preventive and therapeutic strategies for stroke in urban and rural Egypt.

Abstract
BACKGROUND The discovery of direct-acting antiviral agents (DAA) is an outstanding achievement of modern medicine in the current century. The current study aimed to explore the effectiveness and safety of two regimens sofosbuvir (SOF) in combination with either ribavirin (RBV) or simeprevir (SMV) in chronic hepatitis C (CHC) genotype (GT) 4 patients in Egypt. METHODS A total of 201 patients, treatment-naïve and experienced, with CHC GT4 infection were allocated into two groups based on the type of the regimen used. All eligible patients were treated orally with SOF plus daily oral weight-based RBV (24 weeks; group 1), or SOF plus daily oral SMV (12 weeks; group 2). RESULTS In the patients who received SOF/RBV therapy for 24 weeks, a sustained virological response (SVR12) was achieved by 89% (90/101) of all patients, 92% (49/53) of naïve patients and 85% (41/48) of experienced patients. In the SOF/SMV group, the SVR12 rate was 92% (92/100) for overall patients, 93% (70/75) of naïve patients and 88% (22/25) of experienced patients. Adverse events (AEs) were reported in 70% of patients in the SOF/RBV group and 42% patients in the SOF/SMV group. The most common AEs in both groups were fatigue, headache, nausea, and dyspnea. CONCLUSIONS The present comparative study suggests that both SOF/RBV and SOF/SMV combination regimens are highly effective in CHC GT4 treatment. However, the two-DAA regimen (SOF/SMV) may offer well-tolerated treatment, with a shorter duration and better safety compared to SOF/RBV.

Abstract
GAPO syndrome is a very rare disorder characterized by growth retardation, alopecia, pseudoanodontia and progressive optic atrophy. It is caused by biallelic mutations in the ANTXR1 gene. Herein, we describe the clinical and molecular findings of seven new patients with GAPO syndrome. Our patients presented with the characteristic clinical features of the syndrome except for one patient who did not display total alopecia till the age of two years. Strikingly, optic atrophy and glaucoma were observed in all patients and one patient showed keratopathy in addition. Moreover, craniosynstosis was an unusual associated finding in one patient. Mutational analysis of ANTXR1 gene identified five novel homozygous mutations including two frameshift, two splice site and a large intragenic deletion of exon 3. Our results reinforce the clinical characteristics of the syndrome, expand the mutational spectrum and provide more insights into the role of the ANTXR1 protein in the regulation of extracellular matrix.

Abstract
INTRODUCTION New regimens involving direct-acting antiviral agents (DAAs) have recently been approved for the treatment of hepatitis C virus (HCV) genotype 4 (GT4). The current study aims to assess the efficacy and safety of sofosbuvir (SOF) with pegylated interferon (PegINF)/ribavirin (RBV) for chronic HCV GT4 patients at the beginning of the interferon-free era. MATERIAL AND METHODS Between March 2015 and November 2015, 99 patients (59 naïve and 40 experienced) infected with HCV GT4 were enrolled in the study. Eligible patients received daily oral 400 mg SOF, RBV (body weight: < 75 kg, 1000 mg; < 75 kg, 1200 mg), the dose modified according to patient tolerability, plus 180 μg PegINFα-2 once weekly for 12 weeks. RESULTS Among the patient cohort, sustained virological response 12 weeks after the end of treatment (SVR12) was achieved by 88% (87/99) of all patients, by 93% (55/59) of naïve patients and by 80% (32/40) of experienced patients. Regarding treatment failure, the data recorded 12% (12/99) of patients (4 null responses and 8 relapsers). Otherwise, the most common adverse events observed during the study included headache, nausea, fatigue, dyspnea, influenza-like illness, anemia, and leukopenia. CONCLUSIONS SOF combination-based therapies were considered promising choice regimens for chronic HCV infection. The present findings suggest that the combination of the SOF/PegINF/RBV regimen was effective for Egyptian patients with HCV GT4. The recorded adverse events and viral outcome revealed the high need for further efforts to minimize the side effects of the current regimen and/or replace PegINF with additional potent DAA(s) to increase SVR12 to achieve 100%.

Abstract
Objective: To discover the possibility of using microRNA155 (miRNA155) expression level as a biomarker of Behçet's Disease (BD) activity or remission. Methods: Thirty BD patients’ white blood cells (WBCs) miRNA155 expression was measured and compared to WBCs miRNA155 expression in 15 healthy subjects. Assessment of disease activity was done using Behçet's Disease Current Activity Form (BDCAF). Results: miRNA155 expression significantly decreases with the increase of BD activity scored by BDCAF. Conclusion: Increased miRNA155 may be used as a biomarker of BD remission and thus in the disease follow up. There could be a prospect of treating the disease via microRNA 155 effect enhancement.

Abstract
BACKGROUND AND AIM Clinical studies evaluating the efficacy of daclatasvir (DCV) for treatment of chronic hepatitis C virus (HCV) genotype 4 (GT4) infection are scarce. This study aims to evaluate the efficacy and safety of DCV plus sofosbuvir (SOF) with or without ribavirin (RBV) for treatment of Egyptian patients infected with HCV GT4. METHODS Between April 2016 and March of 2017, a large cohort of 946 patients with chronic HCV GT4 was enrolled for completing the treatment. Patients were classified into two groups: group 1 (easy to treat) was treated with a dual therapy of SOF/DCV daily for 12 weeks and group 2 (difficult to treat) was treated with a triple therapy of SOF/DCV/RBV daily for 12 weeks. Efficacy and safety of the treatments were estimated, and baseline characters associated with sustained virological response at 12 weeks post-treatment (SVR12) were investigated. RESULTS Among the patient's cohort, SVR12 was achieved by 94% (891/946) in the overall patients, by 95% (718/758) in the easy-to-treat group, and by 92% (173/188) in the difficult-to-treat group. The most common adverse events recorded were fatigue, headache, nausea, asthenia, and gastrointestinal troubles. No patient discontinued treatment due to severe adverse events. CONCLUSION The findings from the present study suggested that SOF/DCV (with or without RBV) regimen exhibited high effectiveness, was well tolerated in the treatment of chronic HCV GT 4, and revealed itself as a better option for patients with advanced liver disease, making the eradication of HCV a more realistic target to achieve.

Abstract
BACKGROUND The current standard of care for patients with chronic hepatitis C virus (HCV) infection is a combination of direct-acting antiviral agents (DAAs). However, rare clinical trials have been reported on the combination regimen of sofosbuvir (SOF) with ombitasvir, paritaprevir, and ritonavir (OBV/PTV/r) plus ribavirin (RBV) for treated patients with HCV genotype 4 (GT4) infection. AIMS To clarify the retreatment efficacy and safety of the recent regimen, SOF with OBV/PTV/r + RBV, for chronic HCV GT4-experienced patients who failed treatment with DAA-based regimens. METHODS A total of 113 treatment-experienced patients were allocated for the completion of their treatment period. The enrolled patients were treated orally with SOF plus a fixed dose combination of OBV/PTV/r + RBV, which was administered orally based on the patients' tolerability. The primary end point was a sustained virological response (HCV RNA < 15 IU/mL), observed 12 weeks after the end of the treatment (SVR12). RESULTS Among all patients, the treatment-experienced patients with SOF plus OBV/PTV/r + RBV had a higher SVR12 rate (97%; 109/113). Further, SVR12 was achieved by 98% (81/83) of non-cirrhotic patients and 93% (28/30) of cirrhotic patients. Additionally, the most common adverse events reported included fatigue, headache, insomnia, nausea, and dyspnea. CONCLUSIONS The recent multi-targeted regimen of SOF plus OBV/PTV/r + RBV was well tolerated and achieved excellent SVR rates among retreatment-experienced Egyptian patients with prior DAA treatments failure, thus providing an alternative regimen for the retreatment of difficult-to-cure HCV GT4 patients.

Abstract
OBJECTIVES To assess the inter-observer agreement of standard joint count between experienced Rheumatology professor (Prof) and young Rheumatology fellow (candidate), and to compare disease global assessment between professor, young candidate and patients. METHODS This study included one hundred rheumatoid arthritis patients. For all patients independent clinical evaluation was done by two rheumatologists (professor and candidate) for detection of tenderness in 28 joints and swelling in 26 joints. The study also involved global assessment of disease activity by the provider (Prof and candidate) (EGA) as well as by the patient (PGA). The EGA was determined without previous knowledge of the patient's laboratory test results. RESULTS A highly significant accordance (correlation) between professor and candidate was found in both the number of tender joints (p<0.001) (r=0.946), and the number of swollen joints (p<0.001) (r=0.797). Regarding swollen joints, the highest agreement was in right knee (0.929), while poor agreement was found in the right 5th MCP (0.049). Regarding tender joints, the highest analogy was in the right elbow (0.899), in contrast to the left 3rd PIP (0.462) which showed the least congruence. Agreement study using kappa measurement for disease global assessment showed: moderate agreement (between professor and candidate) (0.405), fair agreement between (professor and patient) (0.213), fair agreement between (candidate and patient) (0.367). CONCLUSION Inter-observer reliability was better for TJCs than SJCs. Regarding SJCs agreement was better in large joints such as the knees compared to the small joints such as the MCPs. Disease global assessment may show discrepancy between patients and physicians.

Abstract
Objective: We assessed the possibility of using mitochondrial (mt) DNA deletion as a molecular biomarker for disease progression in HCV-related hepatocellular carcinoma (HCC) and to identify its association with folic acid status. Methods: Serum folic acid and lymphocytic mtDNA deletions were assessed in 90 patients; 50 with HCC, 20 with liver cirrhosis (LC), and 20 with chronic hepatitis C (CHC) compared to 10 healthy control subjects. The diagnostic accuracy of mtDNA deletions frequency was evaluated using receiver-operating characteristic (ROC) curve analysis Survival analysis was performed using the Kaplan-Meier method. Differences in the survival rates were compared using log-rank test. Result: Our data revealed a significant elevation of mtDNA deletions frequency in the HCC group compared to the other groups (P-value <0.01). Also, our data showed a significant correlation between folate deficiency and high frequency of mtDNA deletions in patients with HCV-related HCC when compared to the other groups (r= -0.094 and P-value <0.05). Moreover, the size of the hepatic focal lesion in the HCC patients was positively correlated with mtDNA deletions (r= 0.09 and P-value <0.01). The median survival time for the HCC patients with high frequency of mtDNA deletions (∆Ct ≥3.9; 5.7+ 0.6 months) was significantly shorter than those with low mtDNA deletions frequency (∆Ct < 3.9; 11.9+ 0.04 months, P-value <0.01). Conclusion: Our data provided an evidence that lymphocytic mtDNA deletion could be used as non-invasive biomarker for disease progression and patients’ survival in HCV-related HCC. Also, our findings implied a causal relationship between the folate deficiency and the high mtDNA deletions frequency among Egyptian patients with HCV related HCC.

Abstract
Chronic lymphocytic leukemia (CLL) is a common lymphoid malignancy that has a highly variable clinical course. Genomic features as zeta-chain-associated protein kinase 70 (ZAP70) expression and CD38 expression provide further differentiation of disease prognosis. Extensive studies have confirmed the oncogenic activities of IL-9 in lymphoma. The aim of the current study was to investigate the contribution of IL-9 expression to the pathogenesis of CLL and its correlation to other prognostic parameters. This study was conducted on 80 patients at diagnosis with CLL and 80 healthy controls. Using real time polymerase chain reaction and enzyme linked immunosorbant assay, IL-9 mRNA expression and its serum level were compared between patients and controls. They were both correlated with other prognostic factors. RESULTS There was an overexpression of IL-9 in CLL patients that correlated with modified Rai staging, ZAP70, CD38 and all hallmarks of an active and aggressive disease. The correlation between IL-9 upregulation and patient characteristics provided direct clinical evidence for its contribution to the pathogenesis of CLL. In conclusion, significantly higher expression of IL-9 measured at both the mRNA and the protein levels in patients with CLL that correlates with more complex course of the disease and worse prognosis may allow one to speculate its importance in the pathogenesis of the disease and its possible impact on prognosis.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. It was reported to account for about 4.7 % of chronic liver disease in Egyptian patients. The present study aimed at studying the different factors that may be implicated in the relationship of schistosomiasis mansoni with HCC in Egypt. A total of 75 Egyptian patients with primary liver tumours (HCC) were enrolled in this study. They were subjected to full history taking and indirect hemagglutination assay (IHA) for the diagnosis of schistosomiasis. According to the results, the patients were categorized into two groups: Group I: 29 patients with negative IHA for schistosomiasis and hepatitis C virus (HCV) positive with no history or laboratory evidence of previous or current Schistosoma mansoni infection. Group II: 46 patients with positive IHA for schistosomiasis and HCV positive. The significant higher proportion of HCC patients in the present study had concomitant HCV and schistosomiasis (61.3 %) compared to HCC patients with HCV alone (38.7 %) suggesting that the co-infection had increased the incidence of HCC among these patients. Analysis of the age distribution among HCC patients revealed that patients in Group II were younger in age at time of diagnosis of HCC with mean age 57.1 years, as compared to patients in Group I with mean age 64.3 years with a highly significant statistical difference between the 2 groups. HCC in Group II was more common in rural residents while it was more common in urban areas in Group I with a significant statistical difference between the 2 groups. Analysis of the sex distribution among the studied groups showed that HCC was more common in males than females in both groups. As regards the aggression of HCC, it was more commonly multifocal and larger in size in patients with concomitant infection than in patients with HCV alone.

Abstract
Expression of extracellular matrix metalloproteinase inducer (EMMPRIN) and fascin have recently received considerable attention as emerging key markers of cell invasion and metastasis in various types of cancers. The present study aimed to characterize the expression of EMMPRIN and fascin in a cohort of bladder cancer patients and to verify the association with clinicopathological characteristics. Immunohistochemical analysis of EMMPRIN and fascin was performed in 125 bladder cancer specimens, including 86 transitional cell carcinoma (TCC) and 39 squamous cell carcinoma (SCC) cases. Overexpression of EMMPRIN and fascin was detected in 71.2 and 83.2% of bladder carcinomas, respectively, while neither was detectable in the normal adjacent epithelium. In SCC, EMMPRIN and fascin expression scores were found to be higher compared to TCC cases (P=0.031 and 0.053, respectively). Higher EMMPRIN and fascin immunoscores markedly correlated with tumor pathological (pT) stage in TCC (P<0.001) and SCC (P=0.004 and 0.001, respectively). High EMMPRIN expression was strongly associated with advanced grades in TCC and SCC (P=0.003 and 0.002, respectively). Cases were then stratified, according to the joint expression status of EMMPRIN and fascin, into four immunoprofiles. A highly significant association was found between various tumor immunoprofiles and pathological stage. Of those, the EMMPRIN-/fascin-positive immunophenotype was closely associated with pT3 and pT4 tumors. The findings suggested an association between increased EMMPRIN and fascin expression and increased progression of bladder cancer. Additionally, these two markers may act in concert to mediate a more aggressive behavior through enhanced tumor cell invasion.
