Few treatment options with variable efficacy results are available for its management. We aimed to illustrate the efficacy of Therapeutic Plasma Exchange (TPE) treatment in COVID-19 patients with resistant CS. Material and methods This research is a prospective pilot study which included ten COVID-19 positive patients with CS state with no response after two doses of tocilizumab. Each patient received three to five TPE sessions according to his/her response. Respiratory status {oxygen (O2) requirements and data of mechanical ventilation} and laboratory markers (IL-6, CRP, ferritin, D dimer, LDH) were assessed before and after TPE. We reported mortality at 28 day of illness. Results Six males and four females were enrolled in the study with a mean age of (52.9 years). Seven patients (70%) were on mechanical ventilation (MV). After TPE, oxygenation parameters and most laboratory markers improved significantly in all patients (p < 0.05). Four patients survived and were discharged (40%). One was on MV and three were not. The four patients had better hypoxic index (PaO2/FiO2 ratio) (˃100 vs <100), started TPE sooner after tocilizumab failure (2–3 vs 5–6 days), needed fewer TPE sessions (3 vs 4–5, p = 0.03), and less duration in ICU (6.5 vs 12.5 days) compared to those who did not benefit. Conclusions In patients with CS state who did not respond well to tocilizumab and steroids, TPE could be a good option. Larger randomized clinical trials are needed to support its use.

The challenge of antibiotic resistance has led to several pharmaceutical companies to abandon the synthesis of new drugs in fear of bacteria developing resistance in a short period hence limiting initial investment return. To this effect, alternative approaches such as the use of bacteriophages to treat bacterial infections are being explored. This review explores the recent advances in phage-mediated antibacterial applications and their limitations. Methods: We conducted a comprehensive literature search of PubMed, Lib Hub and Google Scholar databases from January 2019 to November 2019. The search key words used were the application of bacteriophages to inhibit bacterial growth and human phage therapy to extract full-text research articles and proceedings from International Conferences published only in English. Results: The search generated 709 articles of which 95 full-text research articles fulfilled the inclusion guidelines. Transmission Electron Microscopy morphological characterization conducted in 23 studies registered Myoviruses, Siphoviruses, Podoviruses, and Cytoviruses phage families while molecular characterization revealed that some phages were not safe to use as they harbored undesirable genes. All in vivo phage therapy studies in humans and model animals against multidrug-resistant (MDR) bacterial infection provided 100% protection. Ex vivo and in vitro phage therapy experiments exhibited overwhelming results as they registered high efficacies of up to 100% against MDR clinical isolates. Phage-mediated bio-preservation of foods and beverages and bio-sanitization of surfaces were highly successful with bacterial growth suppression of up to 100%. Phage endolysins revealed efficacies statistically comparable to those of phages and restored normal ethanol production by completely eradicating lactic acid bacteria in ethanol fermenters. Furthermore, the average multiplicity of infection was highest in ex vivo phage therapy (557,291.8) followed by in vivo (155,612.4) and in vitro (434.5).","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":"57 1","pages":"1 - 20"},"PeriodicalIF":0.9,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20905068.2020.1851441","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41784337","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}

This study aimed to assess the risk factors associated with HTLV-1/-2 and HIV co-infected among persons attending a secondary hospital in Ningi, Bauchi State, Nigeria. Methods: Blood samples were collected from 182 HIV infected persons and analysed for anti-HTLV-1/2 IgM and IgG antibodies using commercial Enzyme-Linked Immunosorbent Assay (ELISA) kits. Interviewer-based questionnaire were used to collate sociodemographic and risk factor data of the subjects and clinical history were obtained from participants’ medical records. Results: The seroprevalence of anti-HTLV-1/-2 IgM and IgG were 9.9% and 19.8%, respectively. Out of the 80 ART-naïve, 25 (31.3%) were IgM seropositive. Out of 102 ART-experienced, 11 (10.8%) were anti-HTLV-1/-2 IgM positive. There was a significant association between ART status and seroprevalence of anti-HTLV-1/-2 IgM (p=0.009).

The current study aimed to investigate the performance of the modified Hodge test (MHT) as a phenotypic confirmatory method for the detection of carbapenemase-producing Gram-negative bacilli and to compare it to the gold standard PCR for the detection of carbapenemase production in both non-susceptible and phenotypically susceptible isolates. The latter were expected to harbor silent carbapenemase genes, as suspected from the inappropriate response to carbapenem therapy. Methods Ninety-five bacterial isolates from 75 critically ill patients were collected over 6 months from several ICUs at Cairo University Hospitals. The isolates were subjected to antibiotic susceptibility testing (AST) for carbapenems and were further screened by MHT, followed by genotypic analysis via multiplex PCR. Results Enterobacteriaceae were the most commonly isolated pathogens (55.8% of the total isolates), followed by Acinetobacter spp. (24%). Lower respiratory tract infections were the most common HAIs (42.11%), followed by surgical site infections (27.37%). All isolates demonstrating carbapenem resistance by AST were found to harbor at least one of the following carbapenemase genes: blaKPC, blaOXA-48, blaIPM, blaVIM, and blaNDM-1 . Alarmingly, 97.8% of the isolates which exhibited carbapenem-susceptible profile and negative MHT were harboring carbapenemase genes as confirmed by multiplex PCR. With the exception of one isolate (E. coli) which was not harboring any carbapenemase gene, the remaining 94 bacterial isolates were found to carry either a single or multiple carbapenemase genes. Conclusion The silent dissemination of different classes of carbapenemases even in isolates with negative MHT is a daunting challenge. It necessitates the implementation of strict antibiotic stewardship along with updated and actionable approach to detect non-expressed carbapenemase genes in phenotypically susceptible isolates.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":"56 1","pages":"181 - 188"},"PeriodicalIF":0.9,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20905068.2020.1838749","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45410089","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}

This leads to inconsistency of the results and limits the comparison of the data from different laboratories. Our aim was to provide an applied protocol for ASCS isolation and expansion, study the cell behavior and define their cellular surface markers. ASCs were cultured from both resected adipose tissue (RAT) obtained following abdominoplasty or breast reduction and lipoaspirates (LPA) following laser-free liposuction. Method: the protocol entailed coculturing of stromal vascular fraction (SVF) with RAT as raw pieces using DMEM medium with varying glucose concentration. The coculture protocol aimed to mimic the normal physiological conditions required for cell growth. ASCs were immunophenotyped to define their MSCs surface markers by flowcytometry. Results: ASCs were isolated from coculturing RAT with SVF with fibroblast-like adherent cells morphology. The ASCs yield isolated from LPA was significantly greater than from RAT on day 14 and 28 (p = 0.002, <0.001, respectively). Significant increase in ASCs proliferation rate was detected when ASCs were cultured under high glucose (4.5 g/L) compared to low glucose (1 g/L) condition on day 7 and 14 (p = 0.04, 0.015, respectively). ASCs isolated from both protocols were positive for CD34, CD49d, CD73, CD90 and CD105 and negative for CD3, CD14, CD19, CD45 and HLA-DR. Conclusion: We concluded that the cells harvested by our protocol were ASCs. Hence, our method can be an efficient isolation tool to obtain primary ASCs under culture conditions mimicking normal physiological status. This will help in providing ASCs which can be similar to cells in human tissue for further study.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":"56 1","pages":"42 - 50"},"PeriodicalIF":0.9,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20905068.2020.1750863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44394037","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}

The clinicopathologic profile displayed by this subset diverges from that of HPV-negative HNSCCs. Despite a variety of available tests, there is no consensus on which technique is the best for detection of HPV in HNSCCs. Although this field has received substantial interest within different continents, African and Egyptian populations are not yet well studied within the literature. Methods This cross-sectional study was carried out to detect HPV prevalence in HNSSC and to correlate the viral prevalence with different clinicopathologic parameters as well as with the patients’ outcome. For 51 patients with HNSCC, HPV-16 DNA was determined via PCR, while E6/E7 mRNA was detected employing real-time PCR. Immunohistochemistry (IHC) was performed to assess p16 status. Results P16 was overexpressed in 49% of cases, while HPV-16 DNA was detected in 52.9% of cases, and likewise, E6/E7 mRNA was found in 52.9% of cases. There was a very good agreement between HPV16 DNA and RNA results (κ = 0.843, P-value <0.001). Meanwhile, a good agreement was revealed between HPV16 DNA and p16 IHC results (κ = 0.608, P-value <0.001).
