Responding to Emerging Diseases Requires Multi-disciplinary and One Health Training, Egypt

Background: In Egypt, several infectious diseases of zoonotic origin have emerged in recent years like H1N1, MERSCoV and H5N1, the latter now endemic. Responding to these diseases requires a workforce trained in multi-disciplinary approaches to zoonotic disease research and control. It is difficult to deliver multidisciplinary and one health training globally because of the limited number of higher education programs that support such training. In low and middle-income countries where the impacts of emerging zoonotic diseases are felt more directly there is enthusiasm for such training and the use of e-technology can foster international, long-term collaborations. Objectives: To provide health training for infectious diseases research and to foster multidisciplinary collaboration. Methods: We designed and simultaneously held two training workshops, one focused on pediatric infectious diseases and another on emerging infectious diseases to meet the objective. Both workshops had pre- and post-workshop activities for multi-disciplinary methods with an emphasis on the use of mobile technologies to enhance emerging infectious diseases surveillance and research for public health professionals in Egypt. Faculty and scientists from all universities in Egypt and from the National Research Center were invited to participate. Results: 85 participants attended, 31 abstracts were submitted, and over a 3 year period 3 international grant applications were submitted, and 4 abstracts were presented at international conferences. An online forum was developed to continue building collaboration. Conclusions: Interactive on-site workshops are suitable for providing multi-disciplinary training for disease surveillance, research and disease control. Participants shared the opinion that grant proposal and scientific manuscript writing were important skills that they felt they did not have. Long term investments in workshops of this nature are needed to build upon the excitement generated by these activities

Nucleotide Oligomerization Domain-like receptor 4 (NLR4) Gene Expression and Interleukin 1-β (IL 1-β) Level in Urine Samples Before and After Intravesical BCG Therapy For Treatment of Bladder Cancer

Bladder cancer is the 7th most commonly diagnosed cancer in males worldwide and the 11th when both genders are considered. Seventy five per cent of bladder cancer cases are non-muscle invasive bladder cancer (NMIBC). Bacillus Calmette–Gu rin (BCG) immunotherapy remains the standard intravesical agent for NMIBC. The exact mechanism by which BCG prevents recurrence is unknown. The aim of this study was to evaluate NLR4 gene expression and IL-1β as possible prognostic indicators for NMIBC recurrence and BCG treatment failure, and to detect the difference in their levels among muscle invasive bladder cancer (MIBC) and NMIBC that may aid in primary differentiation between cases. This study was conducted in 30 patients who had NMIBC and 17 patients who had MIBC. Urine samples were obtained in sterile cups before operation. From NMIBC cases, four more samples were obtained as mentioned below. Evaluation of NLR4 gene expression was performed in pre-surgical sample for MIBC and in 4 samples for NMIBC: pre-surgical sample, sample collected 4 hours after the 3rd dose of BCG instillation, and samples collected during follow up (3 and 6 months post-surgically). There was statistical significant increase in NLRP4 expression levels in NMIBC (CT=0.87±1.48) compared to MIBC (CT=2.82±2.07). As far as we searched, no published results were found regarding comparative gene expression levels between NMIBC and MIBC cases. Gene expression in recurrent cases was higher in pre-surgical urine samples than in non-recurrent cases. The expression level further increased up to 21 fold than the pre-surgical level in the sample taken after injection of the 3rd dose of BCG. This level decreased distinctly to become 1-fold increase over pre-surgical level at the 3rd month follow up then to only 0.9-fold at the 6th month. In non- recurrent cases, gene expression level started pre-surgically in much lower levels than those encountered in recurrent cases. There were 11-fold increase in expression level after 3rd dose of BCG instillation and then decreased to be 5.6 folds higher in the sample taken at 3rd month follow up than in presurgical samples. Gene expression further decreased to become 4.1 fold higher in samples taken at 6 month follow up than the pre-surgical levels. IL-1β levels were estimated for NMIBC and MIBC cases in urine samples pre-surgically and during BCG therapy in case of NMIBC before and 4 hours after the 3rd dose and during 3rd month follow-up of those cases for searching its possible use of for primary differentiation between NMIBC and MIBC, and also as a prognostic factor for possible recurrence in case of NMIBC cases. The level of IL-1β was generally higher in pre-surgical samples (0.62±0.12 pg/ml) when compared to its level before the 3rd dose of BCG induction therapy (0.53±0.13 pg/ml). Its level was distinctly higher four hours after administration of the 3rd dose BCG (1.96±0.62 pg/ml) than both previous levels. Levels decreased bellow pre-surgical level at 3rd month follow up (0.57±0.099 pg/ml). The levels of IL-1β estimated in samples collected four hours after the 3rd dose BCG was higher in cases that showed recurrence later on than non-recurrent cases. The levels decreased in both cases and became higher in non-recurrent cases (0.64±0.05 pg/ml) than in cases already developed recurrence at the 3rd month diagnosed during follow-up (0.45±0.05 pg/ml). To conclude, on following NLRP4 gene expression and IL-1β levels during BCG administration among recurrent and non-recurrent cases of thirty NMIBC cases, there was a significant statistical difference in both levels for the samples collected after the third dose BCG, being higher in patients who showed subsequent recurrence at the 3rd and 6th month of follow-up. If these preliminary reported findings will be confirmed in upcoming larger cohort’s studies, it could be promising in prognosis of such cases, with the possibility of early manipulation of individualized treatment schedule, keeping patients most probably prone to encounter recurrence safe from possible side effects of BCG therapy. The assessment of NLRP4 expression and IL-1β levels could help predict failure of BCG therapy, playing an appreciable role in early deciding radical surgery. When comparing NLRP4 expression and IL-1β levels between MIBC and NMIBC cases, increased values were noted among non-invasive ones. This finding may serve as a possible diagnostic tool, which represents a challenging issue. Hence, cut-off values for gene expression and cytokine level are to be specified

Antibiotic consumption as a driver for resistance in Staphylococcus aureus and Escherichia coli within a developing region

Background: This study aimed to provide insight into possible antibiotic drivers of methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli resistant to third-generation cephalosporins (3GCREC) in southern and eastern Mediterranean institutions. Methods: MRSA and 3GCREC susceptibility proportions from 19 regional hospitals, previously published by the ARMed project, were correlated with antibiotic use data from the same institutions. Results: Hospitals reporting below-median MRSA proportions had significantly lower total antibiotic use. MRSA proportions increased with greater use of carbapenems (P = .04). In multivariate analysis, a positive correlation was identified with the use of carbapenems (P = .002), combination penicillins (P = .018), and aminoglycosides (P = .014). No difference was ascertained between 3GCREC proportions and total antibiotic use. In multivariate linear regression, a correlation was identified only for 3GCREC (P = .005), but a negative association was evident for beta-lactamase–resistant penicillins (P = .010) and first-generation cephalosporins (P = .012). Conclusions: The results suggest an association between resistance and antibiotic use, especially for carbapenems and third-generation cephalosporins. These data support the urgent implementation of antibiotic stewardship initiatives in hospitals in developing countries that focus on more judicious use of broad-spectrum formulations.peer-reviewe

International Nosocomial Infection Control Consortium (INICC) report, data summary of 36 countries, for 2004-2009

The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).

Report from IFIC’s Special Interest Group Safe Childbirth Workshop:

Scope of the problem In many parts of the world, very high rates of complications and infections are part of the birth process. Infection prevention is integral to the problem and must be part of the solution. Low cost, effective infection prevention interventions are necessary immediately. 1 Maternal complications of childbirth Each year, more than 529,000 women die from complications during pregnancy, childbirth, or postpartum period. 2 Maternal mortality is inequitably spread throughout the world: nearly all of maternal deaths occur in developing countries. 3 The risk of maternal death is 1 in 75 in developing regions compared to 1 in 7,300 in developed regions, but

Device-associated infection rates in adult and pediatric intensive care units of hospitals in Egypt. International Nosocomial Infection Control Consortium (INICC) findings

► Surveillance of device-associated infections in intensive care units in Egypt is proposed. ► Using INICC methods and CDC-NHSN definitions enabled us to obtain comparative data. ► Systematic surveillance enables benchmarking against other health care settings. ► Device-associated rates in our settings are higher than in developed countries. ► Infection control programs with surveillance must be prioritized in these settings. To determine the rate of device-associated healthcare-associated infections (DA-HAIs) at a respiratory intensive care unit (RICU) and in the pediatric intensive care units (PICUs) of member hospitals of the International Nosocomial Infection Control Consortium (INICC) in Egypt. A prospective cohort DA-HAI surveillance study was conducted from December 2008 to July 2010 by applying the methodology of the INICC and the definitions of the NHSN-CDC. In the RICU, 473 patients were hospitalized for 2930d and acquired 155 DA-HAIs, with an overall rate of 32.8%. There were 52.9 DA-HAIs per 1000 ICU-days. In the PICUs, 143 patients were hospitalized for 1535d and acquired 35 DA-HAIs, with an overall rate of 24.5%. There were 22.8 DA-HAIs per 1000 ICU-days. The central line-associated blood stream infection (CLABSI) rate was 22.5 per 1000 line-days in the RICU and 18.8 in the PICUs; the ventilator-associated pneumonia (VAP) rate was 73.4 per 1000 ventilator-days in the RICU and 31.8 in the PICUs; and the catheter-associated urinary tract infection (CAUTI) rate was 34.2 per 1000 catheter-days in the RICU. DA-HAIs in the ICUs in Egypt pose greater threats to patient safety than in industrialized countries, and infection control programs, including surveillance and guidelines, must become a priority
