With Hemanua in Dublin (Ireland) he has developed an innovative blood separation unit, which is also suitable to produce convalescent plasma for Ebola Virus Disease therapy. He has finished both his studies in Medicine and in Biochemistry in The Netherlands with a doctorate and has extensive practical experience in cell biology, immuno-hematology, infectious diseases, biodefense, and transfusion medicine. 

Abstract:

Sharing public health threat information is a necessity for governments to prevent outbreaks of infectious diseases. Zoonotic diseases are the most dangerous for outbreaks running out of control, as the population does not have natural nor artificial (from vaccination) immune response to new emerging diseases. The recent Ebola Virus Disease outbreak in West Africa was such an example. New diagnostic methods, which can be performed in developing countries lacking critical infrastructure have to be developed to have an early response on (potential) outbreaks. It must be high tech with high reliability, which can be used in rural areas without proper infrastructure. The mitigation of highly infectious and deadly disease pandemics have to be recognized at the source. Sophisticated diagnostic equipment and good calibration, maintenance and interpretation of the results is essential. To identify pathogens at molecular level new technologies are under development. In developing countries military and civilian actors cooperate fruitfully in fighting potential biological threats. In this civil-military cooperation it is not only the biosafety, which has to be considered, but also the biosecurity, as misuse of extremely dangerous strains of microorganisms cannot be excluded. Several zoonotic infectious diseases, like anthrax, small pox and also the hemorrhagic fevers like Ebola Virus Disease are listed as potential bioweapons. With this extra threat in mind, both biosafety and biosecurity have to be implemented in all mobile or fixed clinical laboratories. An information/computer network with a cloud in which essential information can be traced, helps in early detection of outbreaks of ‘new’, mostly zoonotic, infectious diseases. The same technology helps in the forensic aspects in case of a bioterror attack.

Abstract:

Clinical trial is a systematic study of new drugs in human subjects to generate data for discovering, verifying the clinically, pharmacological and adverse effects with the objective of determining safety and efficacy of the new drug. ICH GCP provides the guidelines as an international ethical and scientific quality standard to design, conduct, report and record trials conducted on the human participants. India has the potential to contribute meaningfully to global clinical drug development as the value of clinical research in India is being appreciated. Recently, pharmaceutical companies that are involved in clinical trials are being trailed by a growing concern over the clinical research ethics followed in India. In India, pharmaceutical companies carry out about 60% of clinical trials, while the other 40% are handled by CROs in India. Clinical trials are more than 50 percent cheaper in India compared to developed countries. Global pharmaceutical companies are contracting their projects with Indian companies for several reasons: increasing profit, cost-reduction process of drug development and fast process of regulatory approval & fostering a less hostile environment among the world’s impoverished ill. It is advantageous to perform clinical trials in India as it offers large patient pool, low cost of doing business, availability of expert researchers and huge market opportunities. Top multinational pharmaceutical companies like Pfizer, Glaxo Smith Kline, Aventis, Novartis, Novo Nordisk, Astra Zenica, Eli Lilly are conducting clinical trials in India apart from the Indian companies like Dr. Reddys, Nicholas Piramal, Cipla and Lupin etc. The country is organizing to attract more and more researchers from around the world to conduct their clinical trial studies in India. The regulatory system is being improved. Laws are being amended to smooth the path of entry. India is now balanced to provide the global pharmaceutical industry high quality and cost-effective contract services to support drug discovery, clinical trial conduct, data management and manufacturing.

Abstract:

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis complex (MTBC) whose natural history traces back 70,000 years ago. In 2016, there were an estimated 10.4 million new TB cases globally, 1.3 million TB-associated deaths, and an additional 374,000 deaths from TB patients with co-infection of HIV-MTBC. Although the number of TB deaths decreased, TB remained one of the top 10 causes of death worldwide. To address TB challenges, the World Health Organization (WHO) has introduced the “End TB Strategy”, which indicates that the phased strategy has progressed from controlling the prevalence of TB (before 2015) to ending the prevalence of TB (2016-2035). The target for 2035 is a 95% reduction in TB deaths and a 90% reduction in the TB incidence rate compared to levels in 2015, and the target for 2050 is less than one TB patient per million people each year. However, challenges of controlling TB infection and developing more effective vaccines remain, and concerted effort will be required to achieve the global TB control strategy formulated by WHO. Vaccination is the most effective way to prevent and control TB. As early as 1890, Robert Koch proposed the first immunotherapy against TB. However, bacilli Calmette-Guérin (BCG) is the only licensed preventive vaccine against TB and has existed for 96 years. Although BCG vaccination can effectively protect infants and young children from TB infection, and prevent severe diseases such as disseminated TB and tuberculous meningitis, it has variable efficacy against pulmonary TB, particularly in adults. Clinical trials conducted on adults in the United Kingdom (UK) have shown that the protective effect of BCG was 60 to 80%. However, studies performed with South African infants have shown that BCG had no protective effect. Reasons for this variability could be explained by several factors, including genetic differences, environmental factors, co-infection, production methods, the diversity of BCG strains, and the impact of poverty and nutrition. The BCG vaccine does not effectively stimulate the T cell mixed population (especially for CD8+ T cells), and the immuno-protective effect of BCG vaccination only persists for 10 to 15 years. Researchers worldwide have reached consensus that the development of more effective vaccines is necessary to compensate for the limitations of the BCG vaccine. With rapid developments in immunology and molecular biology, some novel TB vaccines have become available, including inactivated vaccines, recombinant live vaccines, attenuated live vaccines, subunit vaccines, and DNA vaccines. At present, there are 25 new TB vaccines in clinical trials, of which three vaccines (Vaccae in patients with latent TB infection (LTBI), Mycobacterium indicus pranii (MIP)/Mw, and VPM1002) have reached Phase III clinical trials. Three vaccines (Vaccae, Utilins, and BCG-PSN) have obtained registration certificates from the China Food and Drug Administration and have been widely used to clinically treat TB in China. However, three vaccines (rBCG30, AERAS-422, and H1:LTK63) have been terminated for their disappointing issues after phase I clinical trials. Herein, we review the developmental progress and challenges of these new TB vaccines, and we will also introduce five novel TB vaccines (Utilising, M. smegmatis, AEC/BC02, BCG-PSN, and GX-70) for the first time, which may give a fresh perception into the TB vaccine research field.

Abstract:

A high seroprevalence of human herpesvirus type (HHV-8) in mild cirrhotics is significantly associated with hepatitis activity. Cirrhosis is almost derived from chronic hepatitis. We aimed to evaluate the prevalence of HHV-8 infection in patients with chronic hepatitis. Blood samples collected from 129 patients with chronic hepatitis and 129 age- and sexmatched healthy controls were analyzed for monocyte and platelet counts, hepatitis B surface antigen (HBsAg), anti hepatitis C virus (anti-HCV), HHV-8 antibody and DNA, and alanine aminotransferase (ALT). Mean monocyte and platelet counts were significantly higher and lower in patients than in healthy controls (P = 0.02 and < 0.0001, respectively). Seropositive rate for HHV-8 antibodies was significantly greater in patients (32.6%) than in controls (20.9%, P = 0.04), particularly in patients with HCV infection, or higher plasma ALT levels, or both (P = 0.004, 0.01, and 0.0009, respectively). Antibody titers for HHV-8 in patients also exceeded those in controls (P = 0.02). The mean age of HHV-8 seropositive patients (60.3 years) was significantly older than that of seronegative (52.3 years) (P = 0.0007). Patients aged 55 or older had higher seropositive rate and titers for HHV-8 antibodies than those younger (P = 0.005 and 0.007, respectively). A significantly high HHV-8 seroprevalence is already present in patients with chronic hepatitis before the development of cirrhosis, particularly in patients with HCV infection and/or higher plasma ALT levels. Advancing age seems to play an important role in HHV-8 seroprevalence in a patient with chronic hepatitis.

Title: Positives from the negatives
Speaker
Biography:

Abstract:

Pap smear is a good sample for identification of abnormalities in the cervix. Basic advantages are easy to handle and transport. After receiving the smears to the relevant lab, the medical laboratory technologists have to accept the samples and do the staining procedures. The technologist's responsibility is issuing the reports within 14 days. Because of that rule( issuing date) technologists have to work hard and fast. So difficult to get an ideal conclusion about the smear. (a) Deuto that time of period, some time they apply shortcuts in the staining procedures. They keep the short time period in the running tap water bath for the washing step. That hence excess hematoxylin staining particles will remain on the smear. So that nuclei and the chromatin cannot be seen very clearly. The other one is, they do not use Scott's tap water for the blueing. Nuclear chromatin is a very important factor from which get more information about the abnormal cells. Scott's tap water act as clearing agent and gives more blue contrast. Early abnormalities in the cervix can be missed when the application of the incomplete staining techniques. (b) Some smears covered with 60% of blood. So that is very difficult to find abnormal hypochromic cells. When they don't pay their attention that abnormal cells can be missed. It also misleads the negative results. (c) Some smears are overcrowded. Because they made it using a small part of the slide surface. All the normal and abnormal cells are in the one cells clump. When the screening the smear cannot go through the one by one cell. It also misleads the negative result. (d) Candida infection: In that infection cells get somewhat enlarge. When the screening, once they look candida organism in the smear, they consider only candida infection not the changes of the HPV. Some pap smears having both candida infection and HPV changes. But screeners report candida infection only.

Conclusions: (1) Due to that points, a Qualified technologist with experience must re-examine the random samples from every 100 slides of the negatives. (2) Medical laboratory technologist should be examined 25 slides for the day. Not more than that because they need more time to screen and make a good report.

Results: 2-4% of new cases can be found the form that negatives within 6 months. I think false positives better than false negatives. Because very positives patients who had a low-grade squamous intraepithelial lesion or atypical squamous cells of undetermined significance (ascus) have to repeat their second sample within six months.

Speaker
Biography:

Suliman Qadir Afridi has received his BSc and MSc in microbiology and virology and now he is doing his PhD at the Institute of Virology, Technische Universität München (TUM), Germany. He is a DAAD scholar. He has published 3 papers in reputed journals.

Abstract:

Norovirus (NoV) is responsible for most cases of pandemic and sporadic non-bacterial gastroenteritis outbreaks worldwide. Chronic infections have been described recently and will become more prevalent with increasing numbers of immunocompromised patients. Here, we studied the longitudinally genetic variability leading to immune escape and development of new quasi-species in chronically infected patients. To this aim, a quantitative ELISA was developed to measure NoV-specific IgG level chronically infected patients at different time points after infection. Evolution of NoV capsid gene was then assessed by next-generation sequencing (NGS), molecular dynamic analysis (SASA, RMSD, RMSF, and Radius of gyration) and structural modeling in a total of 20 samples from 5 chronically infected patients. Consensus sequences of all samples were used for genotyping and multiple sequence alignment. Quasi-species was reconstructed with assembly tool. NoV-specific IgG level increased over time, however in one of the patients decreasing the level of antibody was detected 6 months post-infection indicating immune escape of the virus. Alignment analysis revealed several mutations in the capsid gene, especially in the p domain leading to changes in accessibility and confirmation of the B-cell epitopes. A number of reconstructed quasi-species was found to be increased at the onset of infection and decreased after a certain period in chronically infected patients which leads to cure. In conclusion, the present study showed the fast evolution of NoV capsid gene in chronically infected patients leading to structural change and generation of new quasi-species.

Abstract:

Cutaneous leishmaniases with two forms of rural and urban are the endemic diseases and as a health problem in Iran. The aim of this study was the determination of cutaneous leishmaniases in Kermanshah province. (2013-2015) This descriptiveanalytic study was and the statistical society includes individual information with diagnosis during the 2013-2015 in the county health department in combating communicable disease were registered. About 78% of the total 740 cases were male and 22% were female. Most cases were in the age group 20-29 year with 32-48. Most patients had a wound on his body. Most wounds were on hands. The most common seasonal prevalence was in the winter. 27.6% of patients had a history of travel to endemic areas in the past year. The most frequency of infection was in Kermanshah and Ghasre Shirin cities. According to the results obtained in this study and comparison with previous studies conducted in the province, it can be said implementation control and treatment programs conducted by the relevant authorities and the disease is not endemic in Kermanshah. It is also recommended to determine the disease status in the province, in this regard epidemiological studies should be done every few years.

Abstract:

Objective: To retrospectively investigate the distribution and drug resistance of the main pathogens of common surgical infections in general surgery and to provide references for early and reasonable empirical treatment. Methods: The pathogens of the infected tissues, sputum, peritoneal drainage and puncture fluid were collected and identified in our hospital from January 2012 to January 2016. The pathogen type, distribution, and drug resistance were analyzed. Results: A total of 628 strains of pathogens were co-cultured in 397 infected patients. Among the 323 strains of pathogens, Escherichia coli and Klebsiella pneumoniae were 27.55% and 19.20% respectively. The number of pathogens isolated from the sputum samples was 213, and were Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii predominantly, accounting for 44.60%, 17.37%, and 13.62% respectively. 92 strains of pathogens were isolated from intraperitoneal drainage and puncture fluid samples. Escherichia coli and Klebsiella pneumoniae were mainly accounted for 45.65% and 10.87% respectively. Klebsiella pneumoniae, Escherichia coli are highly sensitive to imipenem and meropenem. Enterococcus faecalis is resistant to vancomycin. Pseudomonas aeruginosa in addition to cefazolin and other antibacterial drugs other than ceftriaxone are more sensitive, and Acinetobacter baumannii was with highly multiple drug resistance. Conclusions: Patients with common surgical infection should be mainly Gram-negative bacilli, which are sensitive to carbapenem antibiotics and should be promptly inspected and selected according to the distribution of pathogens and drug susceptibility.

Abstract:

Chronic hepatitis B virus infection is a major cause of HCC worldwide. Long-term monitoring of high-risk markers in chronic HBV carriers is important to identify the ones that need frequent follow-up or uptake prophylactic therapies. Though up to now the methods (e.g. ultrasound) and tumor markers (e.g. alpha-fetal protein) to diagnose HCC has been established, the high-risk markers for HCC incidence and recurrence have not been fully identified, given that HCC tumorigenesis is a complex process regulated by various crosstalks between host and viral factors. The pre-S2 deletion mutant large HBS (LHBS), isolated from the type 2 ground glass hepatocyte, has been found highly associated with HCC. To detect the pre-S deletion in LHBS, we developed a pre-S Gene Chip, which detects the pre-S deletion based on DNA hybridization of the HBS genes in patients to the DNA probes on the chip. We have also recently pursued to develop the ELISA system and sought its clinical application to test the pre-S2 mutant LHBS in clinical serum samples. The performances of the detection systems in clinical specimens have been validated. The products of monoclonal antibodies and respective ELISA systems, as well as Pre-S Gene Chip, have gained the US and Taiwan patent approval. Using these detection methods, we have identified the pre-S2 mutant LHBS as a predictive marker for HCC recurrence after the receiving hepatectomy surgeries.
