So, ongoing efforts to develop MERS-CoV vaccines are mandatory, and their immunity profiles against different antigens and correlation with protection should be assessed. Aim The present study aimed to assess the neutralizing capacity of MERS-CoV spike (S) structural protein as a DNA-based candidate vaccine in mice models. Materials and methods The spike structural protein gene of MERS-CoV was amplified and cloned using pcDNA3.1 (negative) mammalian expression vector and competent Escherichia coli, for immunization of BALB/c mice as a DNA candidate vaccine, followed by a booster dose after 2 weeks. Sera of mice were collected within 8 weeks after prime vaccination for evaluation of the neutralizing capacity of DNA vaccine using plaque reduction neutralization test (PRNT) assay compared with the neutralizing capacity of inactivated whole virus vaccine, and also a group of mice was injected with empty vector in phosphate-buffered saline (PBS); PBS-pcDNA3.1 (negative) was used as a negative control. Results PRNT50 showed complete neutralization in mice vaccinated with inactivated MERS-CoV vaccine (PRNT50 titer, ∼1 : 160) 6 and 8 weeks of first immunization (P<0.01). The negative control group of mice injected with PBS-pcDNA3.1 (negative) did not show any neutralizing antibodies against MERS-CoV at 2, 4, 6, and 8 weeks after prime vaccination. The mice vaccinated with S gene-based DNA vaccine (pcDNA3.1-S) showed a significant increase of neutralizing antibodies against MERS-CoV strain NC163/2014 at week 8 after prime vaccination with PRNT50 titer, ∼1 : 80. Conclusion These results reported that the spike gene-expressed protein is a major immunogenic protein in MERS-CoV, so it would be recommended in future vaccine development.","PeriodicalId":22975,"journal":{"name":"The Scientific Journal of Al-Azhar Medical Faculty, Girls","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89125554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To investigate the intensity of podocyturia in LN as a noninvasive biomarker and its relation to grade of disease activity. Patients and methods This is a case–control study. It was carried out on 60 patients and 20 control. All participants were randomly selected from those admitted in the internal medicine and rheumatology departments in Al Zahraa University Hospital, Al Hussein University Hospital, and Sayed Galal University Hospital in the period from March 2019 to March 2020. These patients were divided into three groups: group I included 20 healthy controls, group II included 20 patients SLE without nephritis, and group III included 40 patients with LN, which was subdivided into IIIA, which included 20 highly active LN cases and IIIB, which included 20 inactive LN cases. Results In the current work, there was a highly statistically significant difference among the studied groups regarding hemoglobin, white blood cells, creatinine, urea, albumin/creatinine ratio, estimated glomerular filtration rate, anti-DNA, C3, C4, erythrocyte sedimentation rate, C-reactive protein, and antinuclear antibody. Moreover, there was a highly significant difference among the studied groups regarding urinary podocyte marker. There was a statistically significant positive correlation between podocyte marker and creatinine, urea, albumin/creatinine ratio, and anti-DNA in all patients. There was a positive correlation between immunoglobulin (Ig) Cγ and urea and between Ig Cκ and albumin/creatinine and a negative correlation between Ig Cκ and C4 in group III A (active LN).

Patients and methods The study included 30 patients with different degrees of sepsis and septic shock in addition to age-matched and sex-matched healthy controls. All patients were subjected to full clinical examination. The clinical condition of the patients was further assessed using acute physiology age chronic health evaluation II score and Sequential (sepsis-related) Organ Failure Assessment score. The performed laboratory investigations included complete blood count, coagulation profile, erythrocyte sedimentation rate, CRP, renal function tests (blood urea, serum creatinine, sodium, and potassium), liver function tests (serum albumin and bilirubin), and pan-cultures. Results Among the studied patients, there were 16 (53.3%) patients with sepsis, seven (23.3%) patients with severe sepsis, and seven (23.3%) patients with septic shock. Six (20.0%) patients died at the end of the study. The patients had a significantly higher CRP (46.6±24.3 vs. 6.7±3.3 mg/dl, P<0.001) and NLR (21.6±2.8 vs. 2.8±1.9, P<0.004) levels when compared with controls.

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia. Not only does HCV increases type 2 diabetes mellitus (T2DM) risk but it also worsens its control and is associated with increased prevalence of diabetes complications. There is interacting relationship between HCV, T2DM, and the degree and severity of liver fibrosis (FIB) and that T2DM is potentially preventable or controllable by curing HCV infection. Our study aimed to evaluate the effect of eradication of HCV by direct-acting antivirals on the glycemic control, indicated by glycated hemoglobin, and liver FIB, indicated by FIB-4 score. Patients and methods We enrolled in our study 200 patients with chronic hepatitis C (with compensated liver function) and T2DM, who were treated with direct-acting antiviral drugs for 12 weeks, and we followed up their fasting blood sugar, glycated hemoglobin %, and FIB-4 score at the beginning of treatment, at the end of treatment, and then after 3 months. Results Overall, 95% of the patients achieved sustained virological response (SVR) and 5% did not (NSVR). Moreover, 80% from SVR achieved improved glycemic control versus only 10% in NSVR. On the contrary, 80.5% of SVR exhibited decrease (improvement) in FIB-4 score versus 70% in NSVR, but the reduction of FIB-4 was more significant in SVR group.

In the majority of cases, hair falls out in one or more well-circumscribed round or oval patches on the scalp or body (AA focalis), but sometimes it can lead to complete loss of hair on the scalp (AA totalis) or, in extreme cases, the entire body (AA universalis). Hair and nails have a common origin, anatomical structures, and may be involved in many diseases. Nails may also be involved in AA; fragility and pitting can be signs of nail dystrophy in AA patients. Nail dermoscopy was initially used only in the assessment of nail pigmentation, but now it is widely utilized for the evaluation and follow-up of many nail disorders. Aim Evaluation of the presence, types, and clinical findings of nail changes in patients with AA by nail dermoscopy. Patients and methods This is a cross-section observational study, including 100 patients with AA. They were subjected to complete history taking, clinical examination (general and dermatological), and the severity of alopecia tool score was calculated for all patients. The finger nail was examined with a dermoscope to clarify the features of nail changes associated with the disease. Results Nail changes were found in (84.0%) of patients of AA, while (16.0%) have not shown nail changes. The most common nail change was scaly cuticle (75%) of the patients. There was a highly significant positive correlation between nail changes in patients having AA with severity of alopecia tool score and duration of the disease. There was no statistical significant correlation regarding sex, age of the patients, and dermoscopic hair features of AA. Conclusions From this study, we have found that scaly cuticle is the most common nail change in AA patients followed by scales in the lateral nail fold. Also, it can be concluded that nail changes in AA related to the disease severity and the duration of disease, but they are not related to the age, sex of patients, and dermoscopic findings of AA.","PeriodicalId":22975,"journal":{"name":"The Scientific Journal of Al-Azhar Medical Faculty, Girls","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87548480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim The aim of this work is to evaluate the possibility of anticipation of histopathological tissue diagnosis for a mediastinal lymphadenopathy specimen taken by mediastinoscopy on the basis of preoperative CT findings for patients admitted in Al-Zahraa University Hospital in the Cardiothoracic Surgery Department. Patients and methods Thirty patients were included in this study, admitted in the Cardiothoracic Surgery Department of Al-Zahraa University Hospital from December 2019 to May 2020. All patients had received a diagnosis by CT chest and invasive method in the form of mediastinoscopy; then, histopathological results of the mediastinoscopic biopsy were correlated with the CT chest finding to estimate the relationship between both methods of diagnosis in cases with mediastinal lymphadenopathy. Results There is no definitive sign in CT imaging either using the size or shape or distribution to help in reaching the final diagnosis. Therefore, the biopsy is inevitable in all cases.
