Bundle care approach to reduce device associated infections in post-living-donor-liver transplantation in a tertiary care hospital, Egypt.

BACKGROUND: Device-associated infections (DAIs) are a significant cause of morbidity following living donor liver transplantation (LDLT). We aimed to assess the impact of bundled care on reducing rates of device-associated infections. METHODS: We performed a before-and-after comparative study at a liver transplantation facility over a three-year period, spanning from January 2016 to December 2018. The study included a total of 57 patients who underwent LDLT. We investigated the implementation of a care bundle, which consists of multiple evidence-based procedures that are consistently performed as a unified unit. We divided our study into three phases and implemented a bundled care approach in the second phase. Rates of pneumonia related to ventilators [VAP], bloodstream infections associated with central line [CLABSI], and urinary tract infections associated with catheters [CAUTI] were assessed throughout the study period. Bacterial identification and antibiotic susceptibility testing were performed using the automated Vitek-2 system. The comparison between different phases was assessed using the chi-square test or the Fisher exact test for qualitative values and the Kruskal-Wallis H test for quantitative values with non-normal distribution. RESULTS: In the baseline phase, the VAP rates were 73.5, the CAUTI rates were 47.2, and the CLABSI rates were 7.4 per one thousand device days (PDD). During the bundle care phase, the rates decreased to 33.3, 18.18, and 4.78. In the follow-up phase, the rates further decreased to 35.7%, 16.8%, and 2.7% PDD. The prevalence of Klebsiella pneumonia (37.5%) and Methicillin resistance Staph aureus (37.5%) in VAP were noted. The primary causative agent of CAUTI was Candida albicans, accounting for 33.3% of cases, whereas Coagulase-negative Staph was the predominant organism responsible for CLABSI, with a prevalence of 40%. CONCLUSION: This study demonstrates the effectiveness of utilizing the care bundle approach to reduce DAI in LDLT, especially in low socioeconomic countries with limited resources. By implementing a comprehensive set of evidence-based interventions, healthcare systems can effectively reduce the burden of DAI, enhance infection prevention strategies and improve patient outcomes in resource-constrained settings.

Carbapenem- and colistin-resistant Enterobacterales in intensive care unit patients in Mediterranean countries, 2019.

Introduction: The colonization of patients by carbapenemase-producing Enterobacterales (CPE) has been associated with heightened mortality, especially in vulnerable individuals within intensive care units (ICUs). Our study aimed to comprehensively assess CPE prevalence among ICU patients across the Mediterranean region pre-COVID-19, conducting a multicenter prevalence study in the first quarter of 2019. Methods: We collected clinical data and rectal or fecal samples from 256 ICU patients for CPE testing. Additionally, we performed whole-genome sequencing on 40 representative CPE strains to document their molecular characteristics. Results: Among the 256 patients, CPE was detected in 73 samples (28.5%), with prevalence varying from 3.3 to 69.0% across participating centers. We observed 13 colistin-resistant CPE strains, affecting three ICUs. Genetic analysis revealed highly diverse E. coli and K. pneumoniae strains, predominantly from international high-risk clones. Notably, blaOXA-48 and blaNDM-1 were the most prevalent carbapenemase genes. Molecular typing uncovered potential patient clusters in six centers. Significantly, longer hospital stays were associated with increased CPE carriage (p < 0.001). Nine centers across Morocco, Tunisia, Egypt, and Lebanon voluntarily participated. Discussion: Our study provides CPE prevalence in Mediterranean ICUs and reaffirms established CPE presence in this setting but also provides updates on the molecular diversity of CPE strains. These findings highlight the imperative of reinforcing infection control measures in the participating ICUs to curtail escalated mortality rates, and of strictly applying isolation measures around patients originating from the Mediterranean region when transferred to other healthcare institutions.

Leptin Rs7799039 polymorphism is associated with type 2 diabetes mellitus Egyptian patients.

BACKGROUND: Leptin (LEP) is an anti-obesity hormone that regulates food intake, energy expenditure, and glucose metabolism. The genetic variants in LEP and the LEP receptor (LEPR) gene may play an important role in the pathogenesis of type 2 diabetes mellitus (T2DM) and obesity. The current study aimed to investigate the association of serum LEP levels, and LEP polymorphisms in LEP (rs7799039, 2548 G/A) with T2DM in Egyptian patients. METHODS: A total of 205 subjects were included in the present case-control study, consisting of 100 T2DM patients and 105 healthy controls. The anthropometric, psychometric, and biochemical measurements were taken from all the subjects. The genotyping of LEP gene variants was carried out by polymerase chain reaction TaqMan technology. Serum LEP levels were measured by the ELISA technique. RESULTS: T2DM patients had significantly elevated levels of glycated haemoglobin (HbA1c), fasting blood sugar (FBS), postprandial blood sugar (PPBS), international normalisation ratio (INR), creatinine, urea, cholesterol, triglyceride (TG), and low-density lipoproteins (LDL) and significantly decreased high-density lipoprotein (HDL) compared to healthy subjects. serum LEP levels were significantly decreased p (<0.001) as compared to the control group. LEP gene SNP rs7799039 was associated with an increased diabetic risk with A allele being more frequent in T2DM patients than control subjects. The distribution of the AA genotype and GA genotype of LEP SNP rs7799039 was higher in the diabetic group than control one. In addition, AA + GA genotype carriers had significantly elevated HbA1c, FBS, PPBS, TG, and LDL levels and on the contrary, decreased serum LEP levels compared to GG homozygotes. CONCLUSION: The genetic polymorphism rs7799039 showed a highly significant correlation with blood LEP. The co-dominant and dominant models of the LEP genetic polymorphism (rs7799039, 2548 G/A) were shown to have a significant correlation with complicated and uncomplicated diabetes individuals, but we have found that serum LEP levels were inversely related with control and diabetes patients. A positive significant association was found between LEP genetic polymorphism (rs7799039, 2548 G/A) and serum LEP in patients and controls. LEP levels and its rs7799039 genetic variant may play a vital role in increasing T2DM susceptibility.

The present study revealed a positive significant association between the leptin (LEP) genetic polymorphism rs7799039, fasting blood sugar, and post-prandial blood sugar.LEP levels might be utilised to predict T2DM. The AA genotype of LEP rs7799039, 2548G/A (co-dominant model) raises the risk of diabetes compared to the GA genotype, and the A alle is considered a risk factor OR = 1.66.A positive significant association was found between LEP genetic polymorphism (rs7799039, 2548G/A) and serum LEP in patients and controls.

Role of dexmedetomidine in modifying immune paralysis in patients with septic shock: randomized controlled trial.

BACKGROUND: Immune paralysis can be defined as a hypoinflammatory state associated with the incapacity of the immune system to release proinflammatory mediators despite the clearance of pathogens by antimicrobials. Persistent immune paralysis leads to failure to eradicate primary infections with a substantial increase in the risk of multiorgan dysfunction and mortality. The state of immune paralysis is caused mainly by the diminished ability of monocytes to release proinflammatory cytokines in response to endotoxin. This phenomenon is known as endotoxin tolerance. This study aimed to assess the role of dexmedetomidine in modifying immune paralysis in septic shock patients. METHODS: Twenty-four patients with septic shock were randomized into two groups of 12 patients. A continuous intravenous infusion of dexmedetomidine started at 0.15 µg kg-1 hr-1 and adjusted by 0.15 µg kg-1 h-1 to a maximum of 0.75 µg kg-1 h-1 (10 ml h-1), while midazolam was started at 1 mg h-1 (2 mL hr-1) and adjusted by 1 mg h-1 to a maximum of 5 mg h-1 (10 mL h-1). All infusions were adjusted by increments of 2 mL/hr-1 to maintain blinding. Serum levels of CD42a+/CD14+, HLADR+/CD14+, CRP, IL-6, IL-10 and TNF-α were measured at baseline (T1), 12 h (T2), and 24 h (T3). RESULTS: Treatment with dexmedetomidine yielded no significant difference in CD42a+/CD14+, HLADR+/CD14, CD24b-MFI, HLADR-MFI, IL6 and TREM1 at all time points when compared with midazolam treatment. There was no significant difference in TLR levels between the two groups. Cardiac output in the dexmedetomidine group showed a significant decrease at 6, 12 and 24 h (P = 0.033, 0.021, and 0.005, respectively) compared with that in the midazolam group. CONCLUSION: Our results indicated that dexmedetomidine did not affect CD42a+/CD14+ and HLA-DR+/CD14+ expression in septic patients. Furthermore, cytokine production and inflammatory biomarkers did not change with dexmedetomidine infusion.

Evaluating the Feasibility of Pro-Neurotensin and 25-Hydroxyvitamin D3 as Possible Indicators for Type 2 Diabetes Mellitus and Its Complications.

(1) Background: Type 2 diabetes mellitus (T2DM) and metabolic syndrome are associated with decreased vitamin D. In contrast, high pro-neurotensin (pro-NT) levels are linked with an increased risk of T2DM and cardiovascular disease. We aimed to determine the validity of pro-NT and 25-dihydroxy vitamin D3 levels as predictors for T2DM complications; (2) Methods: One hundred T2DM, and one hundred healthy volunteers participated in this case-control study. Their Pro-NT and 25-hydroxyvitamin D3 levels were evaluated using the ELISA technique; (3) Results: Pro-NT and 25 (OH) vitamin D3 have significant validity and accuracy in T2DM prediction, 84.5%, and 90.5%, respectively (p = 0.001). At a value of <29.5, 25-Hydroxy vitamin D3 showed 88% sensitivity and 93% specificity in predicting T2DM. At a value of >124 Pmol/L, Pro-NT showed 81% sensitivity and 88% specificity in predicting T2DM. At a value of 16.5, 25-Hydroxy vitamin D3 had 78.4% sensitivity and 68.3% specificity in predicting T2DM complications. At a value of >158 pmol/L, Pro-NT predicted T2DM complications with 67.6% sensitivity and 56.0% specificity; (4) Conclusions: 25 (OH) Vit D3 and Pro-NT could identify T2DM patients and predict T2DM complications. More extensive research is required to adequately validate this novel perspective with a large population study.

Allelic Discrimination of Vitamin D Receptor Polymorphisms and Risk of Type 2 Diabetes Mellitus: A Case-Controlled Study.

(1) Background: Type 2 diabetes mellitus (T2DM) is one of the rapidly growing healthcare problems, and several vitamin D receptor (VDR) polymorphisms seem to modulate the risk of T2DM. Our research was designed to investigate the allelic discrimination of VDR polymorphisms and T2DM occurrence risk. (2) Methods: This case-control research included 156 patients with T2DM and 145 healthy control subjects. Most of the study population were males 56.6% vs. 62.8% in the case and control groups, respectively. Genotyping for VDR single nucleotide polymorphisms (SNPs), rs228570 (Fok1), rs7975232 (Apa1), and rs1544410 (Bsm1) was compared between both groups. (3) Results: There was a negative link between vitamin D levels and insulin sensitivity. A significant difference was noted in the allelic discrimination of VDR polymorphism rs228570 and rs1544410 between the study groups (p < 0.001). No difference was observed in the allelic discrimination of VDR polymorphism rs7975232 between the groups (p = 0.063). Moreover, T2DM patients had significantly higher levels of fasting blood sugar (FBS), glycated hemoglobin HbA1c, 2-h post-prandial blood sugar (PP), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic-pyruvic transaminase (SGPT), total cholesterol, and triglycerides (p < 0.001), while High-Density Lipoprotein (HDL) Cholesterol (HDL-C) was significantly decreased (p = 0.006). (4) Conclusions: VDR polymorphisms had a positive association with T2DM risk among the Egyptian population. Further large-scale research using deep sequencing of samples is strongly urged to investigate different vitamin D gene variants and interactions, as well as the influence of vitamin D on T2DM.

Human ACE-2, MCP1 and micro-RNA 146 as Novel Markers for COVID- 19 Affection and Severity.

BACKGROUND & AIMS: Coronavirus disease - 2019 (COVID-19) is a major pandemic that causes high morbidity and mortality rates. AIM OF THIS STUDY: to detect the relations between many risk factors, ACE-2, MCP-1, Micro RNA 146 gene expression, and COVID-19 infection and disease severity. METHODS: This study was carried out on 165 cases of COVID-19 and 138 controls. ACE2 and MCP1 levels were measured in COVID-19 cases and control by ELISA and micro-RNA-146 expression by PCR. RESULTS: We found an increased blood level of ACE2 and MCP1 in COVID- 19 patients than in healthy persons and a significant down-regulation of micro-RNA 146 gene expression in cases than in controls. There was a significant correlation between increased blood level of ACE2, regulation of micro-RNA 146 gene expression and severity of lung affection, a significant correlation was found between increased blood level of MCP1 and thrombosis in COVID-19 patients. Neurological complications were significantly correlated with more viral load, more ACE2 blood level, and down regulation of micro RNA146 expression. CONCLUSION: High viral load, increased blood level of ACE2, and down-regulation of micro-RNA 146 expression are associated with more severe lung injury and the presence of neurologic complications like convulsions and coma in COVID-19 Egyptian patients.

In vitro antibacterial effect of probiotics against Carbapenamase-producing multidrug-resistant Klebsiella pneumoniae clinical isolates, Cairo, Egypt.

BACKGROUND: Searching for a non-antibiotic therapeutic option such as probiotics is gaining momentum nowadays. We aimed to evaluate the in vitro antibacterial ability of cell-free supernatant (CFS) of selected Lactobacillus strains (with probiotic properties) against clinical isolates of OXA-48-producing multidrug-resistant (MDR) Klebsiella pneumoniae separately and in combination with cefoperazone antibiotic. METHODS: Over a period of 8 months, a cross-sectional experimental study involving 590 Klebsiella pneumoniae isolates was done. Our study took place at The Specialized Pediatric Teaching Hospital of Cairo University. Of the 590 Klebsiella pneumoniae isolates collected from blood cultures, pus, endotracheal aspirates, and pleural fluid, only 50 unrepeated clinical isolates of MDR Klebsiella pneumoniae-producing OXA-48-like detected by CHROMID® OXA-48 (bioMérieux, France) were selected for our study. After determining the minimal inhibitory concentration of CFS of ten Lactobacillus strains and cefoperazone each, the synergistic effect of both was tested. RESULTS: Among ten tested Lactobacillus spp., a significant increase in the mean value of inhibition zone diameter with CFS of L. helveticus (14.32 mm) and L. rhamnosus (13.3 mm) was detected separately. On the contrary, an antagonistic activity against all tested isolates was detected upon combination of Lactobacilli with cefoperazone (512 µg/ml). The mean value of inhibition zone diameter of L. helveticus CFS+ cefoperazone was (11.0 mm) and for L. rhamnosus CFS+ cefoperazone was (10.88 mm) (p value <0.001). CONCLUSION: The antimicrobial efficiency of using CFS of Lactobacillus species separately indicates that these therapies may be a substitute treatment strategy against MDR Klebsiella pneumoniae.

Apelin Association with Hepatic Fibrosis and Esophageal Varices in Patients with Chronic Hepatitis C Virus.

Portal hypertension and esophageal varices complicating hepatitis C virus (HCV)-related chronic liver diseases are some of the most devastating sequelae. Angiogenesis is the hallmark of their pathogenesis. Apelin is one of the recently identified angiogenic and fibrogenic peptides. We studied apelin gene expression, apelin (rs3761581) single-nucleotide polymorphism (SNP), and serum apelin level in patients with chronic HCV, and their association with liver fibrosis and esophageal varices in 112 patients with HCV-related chronic liver disease (40 with liver cirrhosis [LC]/low-grade varices, 33 with LC/high-grade varices, and 39 with fibrotic non-cirrhotic liver/no varices) and 80 healthy control subjects. Real-time polymerase chain reaction was used for apelin gene expression assay and apelin rs3761581 SNP analysis in peripheral blood samples. The serum apelin level was measured by ELISA. Apelin gene expression was undetectable in the studied samples. The SNP analysis revealed a greater frequency of the C (mutant) allele among patients compared with control subjects (P = 0.012; odds ratio, 3.67). The serum apelin level was significantly greater in patients with LC/varices (median, 31.6 ng/L) compared with patients without LC/varices (median, 2.9 ng/L; P < 0.001). A serum apelin level cutoff value of 16.55 ng/L predicted the presence of varices, with an area under the receiver operating characteristic curve value of 0.786. A positive correlation was found between serum apelin level and grade of liver fibrosis (r = 0.346, P < 0.001) and portal hypertension (r = 0.438, P < 0.001). In conclusion, the apelin rs3761581-C allele may be associated with the progression of HCV-related chronic liver disease and varices formation, and can be considered a potential therapeutic target to control fibrosis progression. The serum apelin level provided an accurate prediction of the presence of esophageal varices.

Modeling COVID-19 effects on SDGs using system dynamics in Egypt.

The coronavirus disease 2019 (COVID-19) poses a significant threat to achieving the Sustainable Development Goals (SDGs). To address this challenge, a thorough examination of the pandemic's influence on four SDGs in Egypt is presented in a system dynamic model. The addressed goals are related to no poverty (SDG 1), zero hunger (SDG 2), decent work and economic growth (SDG 8), and climate action (SDG 13). The model is simulated over 35 years extending from 2015 to 2050. Furthermore, a web-based interactive learning environment is developed to analyze the interdependencies among public health activities and study the impacts of possible intervention countermeasures or prevention policies. Indicators including poverty line, food insecurity, gross domestic product (GDP) growth rate, and greenhouse gas (GHG) emissions are evaluated to track Egypt's performance in relation to SDGs 1, 2, 8, and 13. According to the simulation model, the poverty line will continue to decline until it reaches around 16% by 2050. According to the significant governmental efforts to follow its vision of 2030, Egypt can achieve a decreasing percentage of food insecurity, reaching 3% in 2030, and this percentage will continue to decrease until it reaches full sufficiency by 2050. The GDP growth rate will rise every year until it reaches 13.71% in 2050. With respect to climate, GHG emissions are predicted to fall to roughly 97 Mt CO2-equivalents by 2050. This approach revitalizes debates about the achievement of SDGs amid the crisis and acts as a powerful tool that aids decision-makers in identifying leverage points to avoid the long-term negative repercussions of the crisis on the economy, people, and environment.

Clonal Diversity and Epidemiological Characteristics of ST239-MRSA Strains.

Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen associated with severe morbidity and mortality and poses a significant threat to public health worldwide. The genetic diversity based on sequence types of MRSA strains was illustrated in previous studies; meanwhile, the diversity along with the predominant sequence type, especially in Egypt, remains unknown. The purpose of the current study was to determine the diversity of the predominant MRSA clone ST239-MRSA (n = 50) isolated from different hosts and clinical samples and to illustrate the correlation between the resistance patterns, toxin genes, and the genetic background in Port-said and El-Sharkia Governorates, Egypt. The ST239-MRSA clone was analyzed by phenotypic antibiotyping and various genotypic assays comprising SCCmec, agr, spa, coa, and coa-RFLP in addition to toxin gene profiles. Most of the analyzed strains (40/50, 80%) were multidrug resistant (MDR), belonged to SCCmec-III, agr-I, and coa genotype I, and harbored sea and pvl genes. A negative correlation between the toxin gene profiles and antimicrobial resistance was recorded. Meanwhile, the correlation between the toxin gene profiles and the genetic background was not observed in this study. Although ST239-MRSA strains belonged to a single sequence type, they exhibited a high degree of phenotypic and genotypic diversity, indicating weak clonality and adaptability. With such diversity, it is assumed that these strains may have undergone different evolutionary processes during transmission events among and/or within a single host or tissue niche.

Efficacy and safety of active vitamin D supplementation in chronic spontaneous urticaria patients.

BACKGROUND: Chronic spontaneous urticaria (CSU) is a common skin disorder affecting negatively patients' lives. Vitamin D deficiency has been reported to be associated to many allergic skin disorders. OBJECTIVE: This study aimed to evaluate the association between the serum level of 25 hydroxy vitamin D and CSU and to assess the efficacy and safety of active vitamin D in management of CSU. METHODS: The study was conducted on 77 patients with CSU and 67 healthy controls, then the 77 CSU patients were randomized to either the study group that received 0.25 µg alfacalcidol daily or the placebo group that received oral placebo for 12 weeks. RESULTS: Serum 25(OH) D was significantly lower in CSU as compared to healthy controls and was negatively correlated to the urticarial severity. After alfacalcidol administration, the study group showed significant higher level of 25(OH) D compared to the placebo group. In addition, the mean serum level of IL6, hsCRP and TNFα significantly decreased in the study group in comparison to the placebo group and as compared to their baseline results. CONCLUSION: Vitamin D deficiency is more common in CSU patients as compared to healthy people and hence, alfacalcidol might have a beneficial role as add on therapy in CSU management with no reported side effects.

Asymptomatic SARS-CoV-2 infection among healthcare workers in a non-COVID-19 teaching university hospital.

BACKGROUND: During the COVID-19 pandemic, most of the published reports on COVID-19 emphasized that health care workers (HCWs) get infected more than the general population representing one of the most vulnerable groups. However, that the real percentage of HCWs infected by SARS-CoV-2 in Egypt remains unknown. The researchers conducted the current study to assess seroprevalence of SARS-CoV-2 IgG among HCWs working in a hospital with no SARS-CoV-2 patients, and to identify the potential factors associated with SARS-CoV-2 IgG seropositivity. DESIGN AND METHODS: The current study is a cross-sectional study carried out among 455 HCWs at Cairo University Hospital. The researchers administered a questionnaire shortly before the SARS-CoV-2 rapid test is performed using closed-ended question format to obtain information on demographic data of the study participants including age, sex, specialty, clinical information including questions about medical conditions, and. history of previous exposure with a confirmed or suspected case of COVID-19, and history of COVID-19- compatible symptoms during the previous 14 days (cough, sore throat, runny nose, fatigue, shortness of breath, fever, headache, vomiting, diarrhea, anosmia, ageusia, and chills). RESULTS: We screened 455 HCWs for SARS-CoV-2 antibodies, 31.4% were in the high-risk group, and 68.6% in the low-risk group. The overall IgG seroprevalence was 36 (7.9%) (95% CI 5.8 to 10.8). The IgG seroprevalence was significantly higher in low-risk group 11% (35/312) versus high-risk group 0.7% (1/143), p<0.001. CONCLUSIONS: Low seropositivity rates for SARS-CoV-2 among HCWs is suggestive of lack of immunity and we are still far from herd immunity.

MALDI-TOF MS Overcomes Misidentification of the Uncommon Human Pathogen Candida famata by Routine Phenotypic Identification Methods.

Candida famata has been associated with the identifiable Candida infections that takes place in human and the identification error of this species possibly will result in misinterpretation of antifungal susceptibility and improper diagnosis; which will have a major effect on the prognosis and therapy of patients. Our objective is to correctly identify Candida spp. collected from patients at the intensive care units, New Cairo University teaching hospital in Cairo-Egypt using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS). Hundred clinically isolated yeast strains were identified using API 20C AUX obtained from patients receiving care at intensive care units. ATB FUNGUS 3 strips were used to detect the minimum inhibitory concentration. Thirty-three non duplicate strains identified as C. famata were subjected to re-identification by MALDI-TOF MS. Our results revealed that isolates were initially identified as C. famata 33%, C. tropicalis 15%, C. albicans 12% and C. parapsillosis 10% using the phenotypic techniques. MALDI-TOF MS analyses results showed that the 33 C. famata isolates are C. tropicalis (n = 29), Trichosporon asahii (n = 2), C. parapsilosis (n = 1), and Aeromonas sobria (n = 1). Antifungal resistance was low in the Candida species, except for reduced susceptibility to itraconazole among C. krusei strains. This report shows that misidentification of C. famata is frequent when using conventional phenotypic methods of identification which result in challenges in treating fungal infections. MALDI-TOF MS is an accurate convenient substitute to classical approaches for fungal identification. In general, antifungal multidrug resistance is uncommon in our studied Candida species and yeast isolates.

The impact of vitamin D supplementation as an adjuvant therapy on clinical outcomes in patients with severe atopic dermatitis: A randomized controlled trial.

Vitamin D supplementation with standard treatment yielded positive clinical outcomes in mild and moderate atopic dermatitis; however, the potential benefit of vitamin D in severe cases remains unclear. This study aimed to evaluate the impact of vitamin D supplementation on response to standard treatment in pediatrics with severe atopic dermatitis. The patients were randomized to receive either vitamin D 3 1600 IU/day or placebo, plus baseline therapy of topical 1% hydrocortisone cream twice daily for 12 weeks. The primary endpoints were the change in mean Eczema Area and Severity Index (EASI) score at the end of the study and the mean percent change in EASI score from baseline to week 12. Eighty-six subjects completed the study. The treated group achieved a significant higher level of 25 hydroxy vitamin D (P < .001) compared to control group at week 12. The mean EASI score was significantly lower in the treatment group compared to placebo group (P = .035). The percent change in EASI score from baseline differed significantly between the supplementation (56.44 ± 29.33) and placebo (42.09 ± 19.22) groups after intervention (P = .039). Vitamin D supplementation could be an effective adjuvant treatment that improves the clinical outcomes in severe atopic dermatitis.

Care Bundle Approach to Reduce Surgical Site Infections in Acute Surgical Intensive Care Unit, Cairo, Egypt.

INTRODUCTION: Surgical site infections (SSIs) are one of the most frequently reported hospital acquired infections associated with significant spread of antibiotic resistance. PURPOSE: We aimed to evaluate a bundle-based approach in reducing SSI at acute surgical intensive care unit of the Emergency Hospital of Cairo University. PATIENTS AND METHODS: Our prospective study ran from March 2018 to February 2019 and used risk assessment. The study was divided into three phases. Phase I: (pre-bundle phase) for 5 months; data collection, active surveillance of the SSIs, screening for OXA-48 producing Enterobacteriaceae and multidrug resistant Acinetobacter baumannii colonizers using Chrom agars were carried out. Phase II: (bundle-implementation) a 6-S bundle approach included education, training and postoperative bathing with Chlorhexidine Gluconate in collaboration with the infection control team. Finally, Phase III: (post-implementation) for estimation of compliance, rates of colonization, and infection. RESULTS: Phase I encompassed 177 patients, while Phase III included 93 patients. A significant reduction of colonization from 24% to 15% (p<0.001) was observed. Similarly, a decrease of SSI from 27% to 15% (p=0.02) was noticed. A logistic regression was performed to adjust for confounding in the implementation of the bundle and we found a 70% reduction of SSI odd's ratio (OR's ratio = 0.3) confidence interval (95% CI 0.14-0.6) with significant Apache II (p=0.04), type of wound; type II (p=0.002), type III (p=0.001) and duration of surgery (p=0.04) as independent risk factors for SSI. Klebsiella pneumoniae was the most prevalent organism during phase I (34.7%). On the other hand, A. baumannii was the commonest organism to be isolated during phase III with (38.5%) preceding K. pneumoniae (30%). CONCLUSION: Our study demonstrated that the implementation of a multidisciplinary bundle containing evidence-based interventions was associated with a significant reduction of colonization and SSIs and was met with staff approval and acceptable compliance.

Genetic diversity of carbapenem-resistant Klebsiella Pneumoniae causing neonatal sepsis in intensive care unit, Cairo, Egypt.

Neonatal sepsis is a great challenge for clinicians and infection control practitioners, especially in facilities with limited resources. Carbapenem-resistant Klebsiella pneumoniae (CRKP) is rapidly increasing and carriages a major threat to neonates. We aimed to examine phenotypes causing neonatal late onset sepsis (NLOS) in comparison with neonatal early onset sepsis (NEOS) with further investigations of genotypes, and genetic relatedness of CRKP in neonatal late-onset sepsis. Our study included 88 neonates diagnosed with sepsis: 58 with (NLOS) and 30 with (NEOS) from November 2015 to April 2016, at neonatal intensive care unit (NICU) of Cairo University Hospital. K. pneumoniae was the most common encountered pathogen in the NLOS group (37.9%) with a mean sepsis score of 6.39 when compared to the NEOS group (p < 0.05). In Klebsiella group, C-reactive protein and interleukin-6 levels were significantly high (p ˂ 0.001) and 56.5% of the isolates were meropenem resistant. The most prevalent carbapenemase gene was OXA-48 which was identified in 14/23 (60.8%) followed by NDM-1 which was identified in 12/23 (52.2%) as detected by multiplex PCR. Coexistence of both carbapenemases was found in 52.2% (12/23). The blaKPC, blaIMP, and blaVIM genes were not harbored in the isolates. By investigating the genetic relatedness of CRKP by pulsed-field gel electrophoresis, 23 isolates of K. pneumoniae revealed various pulsed-field gel electrophoresis (PFGE) patterns, demonstrating that the isolates were non-clonal. Awareness of the existing phenotypes and genotypes is important for proper treatment and infection control practices.

DAAs therapy associated with improved hepatic fibrosis in HCV-GT4 patients co-infected with HIV.

Background: The present work aimed at evaluation of the potential dynamic changes in hepatic fibrosis following treatment of chronic HCV using DAAs in patients coinfected with HIV. Patients and methods: In total, 50 HCV/HIV coinfected patients [age; 34.68 ± 10.38 years, 82% men] were included. For all included patients, liver stiffness measured using transient elastography as well as serum liver fibrosis scores; [fibrosis-4 (FIB-4) score and the aspartate aminotransferase to platelet ratio index (APRI)] were calculated at baseline and at 12 and 24-weeks following 12 weeks therapy of HCV with once daily sofosbuvir 400 mg plus daclatasvir 60 mg. Results: Most of the included patients (70%, n = 35) were on anti-retroviral therapy. SVR24 was achieved by 93.48% of the patients. There was significant serial improvement in baseline liver stiffness measurement (LSM), FIB-4 and APRI among responders; [LSM: baseline, 7.05 ± 4.84 kPa vs. 5.66 ± 2.63 kPa at SVR24, p < 0.001], [FIB-4: baseline, 1.24 ± 1.08 vs. 0.93 ± 0.64 at SVR24, p 0.001) and (APRI: baseline, 0.725 ± 0.66 vs. 0.36 ± 0.19at SVR24, p 0.001) respectively. Conclusion: Treatment of HCV patients coinfected with HIV using DAAs is associated with a rapid significant regression in hepatic fibrosis, as evaluated by FibroScan, FIB-4, and APRI scores.
