Biography:

Dr. Reza Nejat is a board certified Anesthesiologist, FCCM and ECFMG certified. He was graduated from Tehran University of Medical Sciences (TUMS) as a GP and achieved his expertise in Anesthesiology from Iran University of Medical Sciences. Fellowship in Critical Care Medicine at Sina Hospital, TUMS, made him fascinated to molecular medicine with inclination to sepsis and acute heart failure. IVIg has been one of his field of interests and experience for the past 4 years.

In addition to his positions as the chief of few hospitals and as an associate professor in Shahid Beheshti University of Medical Sciences for 8 years, he has 4 published books in the fields of cardiology, nephrology, fluid and electrolyte, nutrition, metabolism and endocrinology. He has established his website on which he publishes his articles. Dr. Nejat has presented a few articles in different conferences. 

Abstract:

Statement of the problem: Intravenous immunoglobulins (IVIG) contains immunoglobulins pooled from the plasma of 3000 to 10000 individual blood-donors. This preparation was developed originally in 1952 as a therapeutic milestone in primary hypo-gamma-globulinemia. IVIG has subsequently been proved to have therapeutic efficacy for an ever-growing number of conditions in diverse fields of medicine. Presuming the protective characteristic of its pluripotent antibody content, IVIg is expected to have explicit impact in sepsis, yet FDA has not approved and Surviving Sepsis Campaign Guidelines (SSCG) 2012 discouraged its administration in adult sepsis.

Methodology: By reviewing of relevant articles searched through internet from 1990 to 2016, the efficacy of IVIg as an adjuvant treatment in improving the outcome in systemic inflammatory response syndrome (SIRS) and sepsis was surveyed. Based on the literature it is discernible that SIRS and sepsis with high rate of mortality in ICUs are actually detrimental much more owing to dysregulated immune system responses overwhelmed by disarray of cytokines and chemokines, declining of endogenous immunoglobulins and even deranged activation or suppression of relevant gene domains. According to the latest definition of sepsis in 2016, this dysregulated host response to infection renders the scene toward organ dysfunction.

IVIg was given to three highly critically ill patients of 95, 37 and 11 years of age, with severe sepsis due to iatrogenic sigmoid perforation, post-ERCP necrotizing pancreatitis and severe multiple trauma following collision with a truck, respectively. Before administration of IVIg the patients was given intensive care with administration of appropriate antibiotics and keeping the energy, fluid and electrolytes in a balance mode. They all recovered from sepsis and were discharged in good health. 

Conclusion: Based on this review article and case report, immune-modulatory characteristic of IVIG may restore the pathobiological host responses to normal and improve the outcome in sepsis.

Abstract:

Background and Objective: Biological weapons like other weapons of mass destruction, including nuclear and radiological weapons are very dangerous in recent years due to characteristics such as the ability to create extensive injury , having incubation period , creating long illness , the ability to spread and epidemic and most importantly non-specific symptoms and difficulty in detection  of bioterrorism attacks are increasingly used by some countries . One of the most important steps to deal with the Bioterrorism threat is microbiological detection of biological agents that can be done in the Microbiology laboratory.

Methods: This study aimed to review the role and actions of microbiology laboratories and specialists needed in passive defense against biological threats. In this study databases like CDC, Medline, Google scholar, PubMed and the World Health Organization (WHO) and other national and international sources have been used.

Results: The basic principle of control bioterrorism attacks is based on the ability to rapidly deliver health services . Microbiology laboratories play a critical role in the rapid and accurate detection of biological agents due to the lack of features such as odor, color and other physical characteristics, diagnosis is difficult and sometimes impossible.Therefore  Microbiology Laboratories should be equipped with advanced  detection and diagnosis methods along with rapid development of Novel biological Agents and Personnel should be trained with current detection methods and  protocols and further with biosafety and biosecurity guidelines for working with bio agents.

Conclusion: With rapid Development in detection systems and methods specially molecular detection protocols and instruments for Biological Agents it will be nesecary for nationas Microbilogy laboratoryies and personel to be trained and equiped and redy for detection of any possible biological incidents.

Abstract:

The progression of human immunodeficiency virus (HIV) is associated with mucosal damage in the gastrointestinal (GI) tract. This damage enables bacterial translocation from the gut and leads to subsequent inflammation. Dextran sulfate sodium (DSS-treatment) is an established animal model for experimental colitis that was recently shown to recapitulate the link between GI-tract damage and pathogenic features of SIV infection. The current study tested the protective properties of ABX464, a first-in-class anti-HIV drug candidate that has demonstrated anti-viral activity in HIV treatment of naïve patients. ABX464 also induced a long-lasting control of the viral load in HIV infected humanized mice after treatment arrest. ABX464 treatment strongly attenuated DSS-induced colitis in mice and produced a long-term protection against prolonged DSS-exposure after drug cessation. Consistently, ABX464 reduced the colonic production of the inflammatory cytokines IL-6 and TNF as well as that of the chemoattractant MCP-1. However, RNA profiling analysis revealed the capacity of ABX464 to induce the expression of IL-22, a cytokine involved in colitis tissue repair both in DSS-treated mice. A comprehensive analysis of the gene expression profiles by RNAseq demonstrated that the expression of IL22 was preferentially induced by ABX464 in mouse bone marrow derived macrophages only upon stimulation with LPS.  Importantly, anti-IL22 antibodies abrogated the protective effect of ABX464 on colitis in DSS-treated mice.
Because reduced IL-22 production in the gut mucosa is an established factor of HIV and DSS-induced immunopathogenesis, our data suggest that the anti-inflammatory properties of ABX464 warrant exploration in both HIV and inflammatory ulcerative colitis (UC) disease.

Biography:

Hailay Gesesew has his expertise in Epidemiology. His multi-method approach assessing in each cascades of HIV care continuum will establish a significant contribution for the AIDS Ending goal. He has been publishing a lot of peer reviewed articles on the area of HIV care in reputable journals. Hiis publications produced from his PhD will improve the HIV care in developing countries especially Ethiopia. Hailay has been serving as a clinician, academician and researcher. 

Abstract:

Background: How Ethiopia’s UNAIDS 90-90-90 targets is progressing was not assessed. We assessed HIV care continuum outcomes as surrogate markers for the 90-90-90 targets. Methodology: Data were collected from a 12 years retrospective cohort from anti-retroviral therapy (ART) clinic in Southwest Ethiopia.  For measuring the UNAIDS diagnosis target, prevalence rate of delayed HIV diagnosis was considered as a surrogate marker. For the treatment target, number of people on ART, number of people who discontinued from ART or transferred out, and number of people who had fair or poor adherence were used as surrogate markers. For the viral suppression target, number of CD4 counts and/or WHO clinical stages were used to assess immunological, clinical and treatment successes and further show the viral suppression. Summary statistics, trends and estimated survival time were reported. Findings: 8172 patients were enrolled for HIV cares in 2003-2015. For the diagnosis target, 34.5% patients knew their status early (43%-children, 33%-adults). For the treatment target, 65% patients received ART, 1154 (21.9%) patients discontinued from ART, 1015 (19.3%) patients on ART transferred out to other sites, 916 (17%) of patients on ART had fair or good adherence. For the virological suppression target, 80.7, 80.3 and 65.8% of patients had immunological, clinical and treatment success displaying an estimated 66% of patients achieved the target. Conclusions: The finding reflects that an estimated 35% of patients knew their status timely, 65% of diagnosed patients received treatment and 66% of patients on ART achieved viral suppression.  This is very far from the UNAIDS 90-90-90 targets underscoring the need for concreted efforts such as use of unmanned aerial systems (or drones) for transporting laboratory specimens, immediate or same day ART initiation, community distribution of ART, runaway packs during conflict, and use of GenXpert for HIV viral load testing would help to hit the target.

He sees patients at his office in Clarksburg, MD (www.clarksburgmed.com) and Fredrick, MD. 

Abstract:

Background: Lyme disease is caused by the bacterium Borrelia burgdorferi, transmitted to humans through the bite of infected blacklegged ticks. CD4/CD8 ratios in healthy adults vary across populations; in the US, a CD4/CD8 ratio ranging from 0.9 to 1.9 is considered to be normal in non-immunocompromised individuals. Lyme disease is diagnosed based on symptoms, physical findings (eg. Rash) and the possiblity of exposure to infected ticks. Labratory testing is helpful if used correctly and performed with validated methods. The US Center for Disease Control (CDC) diagnostic criteria requires the identification of five Western blot IgG bands for a positive diagnosis1, although patients with less than five positive bands have been subsequently diagnosed with Lyme Disease through urine PCR in Nanotrap testing2. Material/methods: 183 patients at two medical centers were evaluated in Lyme endemic communities in Maryland, US. Further investigation of 148 of these patients correlated their CD4/CD8 ratio with their Ig41 band, using one and two tail testing. Results: The mean CD4/CD8 ratio in the 148 patients was 2.41 with a variance of 1.05 and a standard deviation of 1.025. Assuming a normal CD4/CD8 ratio of less than 2, with a 5% confidence interval, the p value on both a one tailed and two tailed test was shown to be 0.00001. Two patients with an initial CD4/CD8 ratio of 2.7 and 2.8 who were IgG 41 positive were subsequently tested with the Nanotrap Urine PCR and found to be positive for Lyme. Conclusions: Increased CD4/CD8 ratio with a positive IgG 41 band appears to be a strong predictor of a subsequent diagnosis of Lyme disease despite current diagnostic guidelines. Further research should not only be directed towards investigating how Borrellia Burgdoferi disrupts immune function, but also towards improving diagnostic guidelines in light of validated diagnostic methods.

He also plans to continue making research in the future regarding the implementation and improvement of health care.

Abstract:

To evaluate the current level of knowledge of Ebola virus and to raise community awareness of the risk factors for Ebola infection among medical and para-medical students given that healthcare workers have been especially vulnerable.
Method:This was a field study carried in the campus of University of Mansoura, Egypt. A stand has been divided into 3 stations: a pre-survey, an awareness station and a post-survey. The questionnaire addressed basic facts about Ebola virus and how to prevent it, its route of transmission, risk of morbidity and mortality, treatments available and countries afflicted.
Results: Out of the 1515 peoples participating in the survey there were 703 females and 812 males. A total of 1336 were medical students. 754 said they had heard about Ebola. The internet was the most common source of knowledge about Ebola, as 1273 students stated it as first choice with TV coming in second, with 242 students. Most were met with the answer ‘I don’t know’ in the pre-survey. In the post-survey after a 10 minutes general awareness session about the Ebola virus, 1470 surveyors agreed that Ebola has currently no effective treatment and leads to death. Moreover, after the quick awareness 1491 surveyors answered positively to the question ‘Is Ebola preventable?’
Discussion, and/or Conclusion:Involving community-especially medical students and healthcare workers- in treatment and prevention of Ebola through providing adequate means of awareness; assessment is crucial to containing the outbreak and limiting its consequences.

Biography:

Abstract:

Background: Onchocerciasis is a neglected tropical parasitic disease (NTD) caused by a filarial nematode worm called onchocerca volvulus and transmitted by the bites of simulium flies. Since 2001, Ethiopia has been committed to implementation of the National Onchocerciasis Control Programme, which was revised during 2012 to undertake elimination through interruption of transmission until 2020. This strategy uses annual or semiannual community-based treatment using the drug Ivermectin.

Objective: This study was aimed at assessing whether the goal of focal transmission interruption attained or not in one of the areas receiving annual community based Ivermectin for more than a decade.

Methods:  A community-based cross sectional study was conducted in selected communities of Metema focus during 2014 and 2015 in North Gondar, Ethiopia. High endemicity before intervention, proximity to the breeding sites and representativeness of the focus within 20-30 km distance between sites was used for selection. The study participants were community residents above the age of 5 years for skin microfilariae survey and children’s born during the period of mass treatment with age below 10 years for Ov-16 IgG4 antibody exposure test. Skinsnip sample collected from left and right iliac crest of 2,986 individuals with sterilized biopsy punch and examined under a microscope after 24 hours’ incubation. Whereas, finger prick samples collected from 3,136 children and dried blood spot (DBS) prepared for Ov-16 ELISA laboratory analysis.
Results: From microscopic examination, no skin snip found positive for microfilaria. ELISA showed 0.25% (8 of 3,136) antibody positive. But molecular assay of skin snip using PCR demonstrated no infective parasite for those 8 sero-reactive children.
Conclusion: The skin microfilarial survey results revealed absence of Onchocerca volvulus in the community and the serology results implied that children born during the period of the intervention are protected from acquiring infection. An entomological assessment appears important to confirm absence of infectious flies in the focus and interruption of focal transmission.

Title: Complication of burn infection
Speaker
Biography:

Abstract:

[Background and Aims] Although there are some cases complicated by toxic shock syndrome (TSS) from wound infections in extensive severe burns patients, they are rare case causing TSS in small range burn in adults.
For the patients suffering from small burn injuries, an intensive care is not usually needed for the primary care, as they admit in the general ward on admission day. However in rare cases these patients’ condition could get worse while having a treatment in the general ward, and they can be forced to move to the ICU until the vital sign gets stable. In this time, it was examined the TSS complicated by small range burn patients in adults. I report these rare cases with some our considerations.
[Methods] I have experienced 5 cases were complicated by TSS at some reason in inpatient treatment in burns to five years from January 2010 to December 2015, two cases are males and three cases are females, 24 years of age to 75 years (average 48.2 years). Of each case TBSA, PBI, sudden change time, outcome were examined .
[Results] TBSA is 3-32 (average 11.2). PBI is 26-76 (average 53.8), sudden change timing injury 4th to 14th or postoperative 1st to 13th, outcome 1 cases in five cases have been died
[Conclusions] Burn patients have low TBSA and PBI, there is a possibility that even easily getting worse. Particularly when complicated by infection, was easily considered caution because they may follow  irreversible course when complicated by TSS. We suggest not to hesitate to move the patients to the ICU as soon and suggest that the teamwork and cooperation of the plastic surgery department and the ICU department are required.

Title: Status of Xpert MTB/RIF Assay Implementation in Ethiopia
Speaker
Biography:

Abstract:

Background: In 2010, WHO has endorsed Xpert MTB/RIF Assay for the diagnosis of tuberculosis (TB) and rifampicin resistance tuberculosis (RR-TB). Following this recommendation, Xpert MTB/RIF Assay has been implemented in Ethiopia since 2012. Monitoring   and   evaluation   of   Xpert MTB/RIF Assay implementation is necessary to ensure the effective and efficient use of resources and to guide the future scale-up.

Objective: To assess the implementation Xpert MTB/RIF for the diagnosis of TB and RR-TB in Ethiopia.

Methodology: Data was collected and analyzed from 87 GeneXpert sites from May to June 2016. A structured questionnaire was used to collect information on staff profile and trainings taken. Data was extracted from GeneXpert machine since the date of installation from 70 GeneXpert sites. Records were reviewed from laboratory register book and from archived laboratory request formats by using a comprehensive assessment tool to evaluate the laboratory personnel competency and clinician’s adherence to the national algorithm.

Result: A total of 80,683 specimens were examined by using Xpert MTB/RIF Assay starting from the date of installation up to June 2016 in 70 GeneXpert sites. Mycobacterium tuberculosis was detected in 12,422 (15.4%) of specimens. From all TB detected results 83.75% (10,403), 12.68% (1,591) and 3.45% (428) were susceptible, resistance and indeterminate to Rifampicin respectively. The error rate was 14.1%. There were 285 Xpert MTB/RIF Assay trained laboratory professionals at 87 GeneXpert sites. An average of 3 trained laboratory professionals were working in each facility. At least one trained laboratory professional was found in each facility, but untrained laboratory professionals were performing Xpert MTB/RIF Assay in 67 facilities. National Tuberculosis Program approved Xpert MTB/RIF Assay testing algorithm was not followed in 36% of sites. Most of the clinicians did not properly fill request papers. Standardized request formats and laboratory log books were not available in 15% and 8% of facilities, respectively. Xpert MTB/RIF Assay results were correctly recorded on the laboratory log book in 87% of sites. Critical result (RR-TB) communication was not appropriate in 25.6% of facilities. Xpert MTB/RIF Assay test results were not archived regularly in 47% of laboratories.

Conclusion: Detection rate of TB with the Xpert MTB/RIF Assay was low. This may be due to inappropriate eligibility screening of the patients. Xpert MTB/RIF Assay showed an advantage for detecting RR-TB cases in peripheral laboratory level, which is important for early detection of drug resistant cases as well as early treatment initiation. Error rate was high in comparing with the expected standard (≤3%). There was 100% Xpert MTB/RIF Assay training coverage; however, in majority of the sites untrained laboratory professionals were performing Xpert MTB/RIF testing. This may probably have negative impact on test results.

Speaker
Biography:

Dr.Neeraj Chhari 34 years is an assistant professor in department of community medicine in Peoples college of medical science & research Centre,Bhopal,India.He has done his MBBS(2008) MD(2012).He has done his”Certificate course in evidence Based Diabetes Management”(CCEBDM) in 2016 which is recognized by Public Health foundation of India(PHFI) & International diabetes Federation(IDF).He is life member of Indian association Preventive & Social Medicine(IAPSM) and World Non communicable disease(WNCD) federation.Dr.Neeraj is basically inclined towards non communicable diseases esp. diabetes and cancer. At his clinic since 2014 he has organized 4 diabetic camps till date .

Abstract:

INTRODUCTION: As the WHO report the Diabetes epidemic is more pronounced in India than anywhere else. Glycated hemoglobin is a form of hemoglobin that is measured primarily to identify the three-month average plasma glucose concentration. The test is limited to a three-month average because the lifespan of a red blood cell is four months (120 days). But RBCs do not all undergo lysis at the same time, so HbA1C is taken as a limited measure of 3 months.OBJECTIVES:To study the level of A1C level in Diabetic and Non diabetic patients in the suburban area to give  recommendations on that basis METHODOLOGY: Cross sectional study was done on the patients coming to clinic during Diabetic camp organized in suburban area of city. RESULTS:Out of 143 T2DM patients the 112(78%) have HBA1C level within the range of 7-9%.Only 7(4.9%) patients have level >11%.37 patients out of 78 who were non diabetic has Hba1c level of more than 6.5%.CONCLUSION:The observational study was conducted in diabetic camp and it was observed that diabetes has encroached the society with large spectrum and Life style modification is needed to prevent.

Biography:

Sumedha Sharma started her research career with her dissertation in the postgraduate degree where she worked on the effect of Ocimum gratissimum on the colon cancer. She qualified various national eligibility test (Indian Council of Medical Research & Council of Scientific & Industrial Research, India) to pursue her goal in research and academics. Her inclination towards research lead her to join the doctorate program where her research was focused on tuberculosis (TB). During her doctorate degree, she was selected as a training participant in AIDS and TB international training and research program (AITRP) sponsored by Fogarty International Centre, NIH, USA where she was trained on microarray technology. Her microarray work on sputum of PTB patients gave an insight to the mycobacterial genome specifically expressed in active TB patients, leading to identification of mycobacterial targets, which can be exploit as potential vaccine and diagnostic candidates. 

Abstract:

Statement of the Problem: Tuberculosis (TB) diagnosis is a one of the major areas of interest to control the spread of TB disease in community. Therefore, there is a need to develop rapid and specific diagnostics easily usable at different health care levels. Our previous work on mycobacterial gene expression pattern in sputum from pulmonary tuberculosis patients lead to identification of newer targets, as potential biomarkers. In view of this, the current study was planned to evaluate the role of these candidate biomarkers in molecular and serodiagnostic tests. Methodology: Three of the genes, Rv0986 & Rv0971 along with one Region of Difference (RD) gene Rv3121, were evaluated for their diagnostic potential in RNA based real time (RT) polymerase chain reaction (PCR). Simultaneously, the peptides from proteins corresponding to these genes along with five other RD genes were evaluated for their serodiagnostic potential using a peptide based enzyme linked immunosorbent assay (ELISA) technique. Findings: The use of the target genes Rv0986, Rv0971 and Rv3121 in a molecular RNA based assay lead to the detection of smear positive patients with 100%, 87% and 94% sensitivity and of smear negative TB patients with 50%, 58% and 67% respectively. However, of all the peptides corresponding to different proteins which were tested in the serodiagnostic ELISA the maximum sensitivity that could be attained was 37% for smear positive PTB patients and 32% for smear negative PTB patients. Conclusion & Significance: A subset of the proteins encoded by the genes expressed by mycobacteria in the sputum have shown less sensitivity for the development of a serodiagnostic assay, but these genes have shown promising results for the development of a RNA based molecular assay that can be optimized further after evaluation in a larger cohort of patients.

S.M.L. Seddiki is a lecturer at University Center of Naama. He had these degrees of undergraduate and graduate at the University of Tlemcen - Algeria. Seddiki’s research contributes to the struggle against fungal nosocomial infections, particularly those caused by Candida sp, he proposed the term: INFECTIVITY to distinguish fungal infections from simple contamination

Abstract:

Invasive nosocomial infections due to Candida species are responsible for increasing the length of stay, cost of hospitalization and morbidity in immunocompromised patients. Their severity and rapid progressivity are owed to the difficulty of diagnosis. Various catheters, which are often used to train a body fluid (blood, urine, infusion, parenteral nutrition, medication ...) inside the body of the patient or vice versa, are susceptible to be altered by Candida sp. and promote the formation of biofilms which consolidates the risk of invasive nosocomial infections; i.e., these structures are considered as a nest for disease because it is not easily eradicate by conventional antifungal therapy. Such as the diagnosis of candidiasis related to catheter is difficult, the differentiation between catheter infection and a simple contamination is essential to establish an antifungal treatment. Our study aimed adapts to yeasts the Brun-Buisson (1987) method which only concerned by bacteria, it’s why we conducted our study between February 2011 and January 2012 at the Hospital University Center of Sidi Bel Abbès-Algeria that aims to evaluate the various types of fungal catheters infectivities (contaminations, colonization and infections) and their corresponding rates, as well as the responsible yeast species. At the end, the ability to form biofilms was checked. The results showed that three types of fungal infectivities of catheters were identified. On the other hand, SEM images showed clearly Candida biofilms on the surfaces of catheters.

Abstract:

Antimicrobial resistance (AMR) is a growing public health concern worldwide and is one of the top health challenges facing humanity in the 21st century. AMR among enterobacteriaceae is rapidly increasing especially to third-generation cephalosporins and carbapenems.  Further, strains carrying mobilized colistin resistance (mcr) genes 1 & 2 have been isolated from humans, food-producing animals, and environment. Uncontrolled use of antibiotics in animals in large scale could be one of the major contributing factors to generation and spread of antibiotic resistance. No studies have been done to evaluate antimicrobial resistance in animals in Qatar. This study aimed at establishing a primary baseline data for prevalence of antimicrobial resistance among food animals in Qatar. 172 fecal samples were obtained from two broiler farms andone live bird market in Qatar and 90 Escherichia coli (E. coli) bacteria were isolated and subjected to antimicrobial susceptibility testing using Etest method. 90% (81/90) of the isolates were resistant to at least one of the 16 tested antibiotics. 15.5% (14/90) of the isolates were colistin resistant, 2.2% (2/90) were extended spectrum β lactamase (ESBL) producers and similar percentage were multi-drug resistant (MDR) to four antibiotic classes. ESBL-producing E. coli and colistin resistant isolates were confirmed using double disc susceptibility testing and PCR, respectively. In Summary, Our results indicates high antimicrobial resistance in food producing animals in Qatar, including ESBL and colistin resistance. Such AMR bacteria could be easily transmitted to humans through consumption of undercooked food or noncompliance with hygiene practices, which mandates prompt development and implementation of stewardship program to control and monitor the use of antimicrobial agents in community and agriculture.
