Abstract
Diabetes mellitus, characterized by impaired insulin signaling, is associated with increased incidence and severity of infections. Various diabetes-related complications contribute to exacerbated bacterial infections, including hyperglycemia, innate immune cell dysfunction, and infection with antibiotic-resistant bacterial strains. One defining symptom of diabetes is hyperglycemia, resulting in elevated blood and tissue glucose concentrations. Glucose is the preferred carbon source of several bacterial pathogens, and hyperglycemia escalates bacterial growth and virulence. Hyperglycemia promotes specific mechanisms of bacterial virulence known to contribute to infection chronicity, including tissue adherence and biofilm formation. Foot infections are a significant source of morbidity in individuals with diabetes and consist of biofilm-associated polymicrobial communities. Bacteria perform complex interspecies behaviors conducive to their growth and virulence within biofilms, including metabolic cross-feeding and altered phenotypes more tolerant to antibiotic therapeutics. Moreover, the metabolic dysfunction caused by diabetes compromises immune cell function, resulting in immune suppression. Impaired insulin signaling induces aberrations in phagocytic cells, which are crucial mediators for controlling and resolving bacterial infections. These aberrancies encompass altered cytokine profiles, the migratory and chemotactic mechanisms of neutrophils, and the metabolic reprogramming required for the oxidative burst and subsequent generation of bactericidal free radicals. Furthermore, the immune suppression caused by diabetes and the polymicrobial nature of the diabetic infection microenvironment may promote the emergence of novel strains of multidrug-resistant bacterial pathogens. This review focuses on the "triple threat" linked to worsened bacterial infections in individuals with diabetes: (i) altered nutritional availability in diabetic tissues, (ii) diabetes-associated immune suppression, and (iii) antibiotic treatment failure.

IJID REGIONS 2021; 1:142-149. [PMID: 35757820 PMCID: PMC9216422 DOI: 10.1016/j.ijregi.2021.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 09/29/2021] [Accepted: 10/19/2021] [Indexed: 11/30/2022]
Abstract
An overall UTI prevalence of 9.2% (90/982) was detected in diabetic patients in Ghana. Multidrug-resistant E. coli and Klebsiella spp. are a cause for concern in diabetic patients. Phylo-groups B2 and D were prevalent, followed by group C. The predominant virulence genes observed were iutA (17.9%) and KpsMTIII (14.3%). Phylo-group B2 had the highest number of VFs, and was resistant to most of the tested antibiotics.
Objectives Our study aimed to determine the etiology of urinary tract infections (UTIs), resistance profiles of isolated bacteria, and virulence factors of Escherichia coli associated with bacteriuria in diabetic patients in Ghana. Methods Midstream urine samples from 982 diabetic patients were tested for uropathogens at the National Diabetes Management and Research Centre in Ghana, using standard bacteriological methods, with antibiogram testing of the isolates using the Kirby–Bauer disk diffusion, as per CLSI guidelines. Polymerase chain reaction (PCR) was used to investigate the phylogenetic groupings and virulence factor (VF) genes of isolated E. coli. Results The overall prevalence of UTIs was 9.2%, and the main uropathogens were Klebsiella spp. (55.6%) and Escherichia coli (31.3%). Age, duration of diabetes, and a previous history of UTIs were risk factors associated with UTI (p-value < 0.05). High levels of antibacterial resistance to cefuroxime (84%), ampicillin (80%), and gentamicin (70.7%) were observed. The distribution of VFs in each phylogenetic group revealed that sfa-iutA-KpsTMII-KpsTMIII genes were associated with group B2, and iutA-ibe were associated with group D. Conclusions The isolated uropathogens were highly resistant, and the E. coli isolates possessed varying VFs. Continuous monitoring of bacteria associated with UTI in diabetics is highly recommended.

Abstract
Chronic and recurrent infections occur commonly in both type 1 and type 2 diabetes (T1D, T2D) and increase patient morbidity and mortality. Neutrophils are professional phagocytes of the innate immune system that are critical in pathogen handling. Neutrophil responses to infection are dysregulated in diabetes, predominantly mediated by persistent hyperglycaemia; the chief biochemical abnormality in T1D and T2D. Therapeutically enhancing host immunity in diabetes to improve infection resolution is an expanding area of research. Individuals with diabetes are also at an increased risk of severe coronavirus disease 2019 (COVID-19), highlighting the need for re-invigorated and urgent focus on this field. The aim of this review is to explore the breadth of previous literature investigating neutrophil function in both T1D and T2D, in order to understand the complex neutrophil phenotype present in this disease and also to focus on the development of new therapies to improve aberrant neutrophil function in diabetes. Existing literature illustrates a dual neutrophil dysfunction in diabetes. Key pathogen handling mechanisms of neutrophil recruitment, chemotaxis, phagocytosis and intracellular reactive oxygen species (ROS) production are decreased in diabetes, weakening the immune response to infection. However, pro-inflammatory neutrophil pathways, mainly neutrophil extracellular trap (NET) formation, extracellular ROS generation and pro-inflammatory cytokine generation, are significantly upregulated, causing damage to the host and perpetuating inflammation. Reducing these proinflammatory outputs therapeutically is emerging as a credible strategy to improve infection resolution in diabetes, and also more recently COVID-19. Future research needs to drive forward the exploration of novel treatments to improve infection resolution in T1D and T2D to improve patient morbidity and mortality.

[PMID: 33446279 PMCID: PMC7809737 DOI: 10.1186/s13756-021-00887-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 01/05/2021] [Indexed: 12/20/2022] Open
Abstract
Background Antibiotic prescribing is common worldwide. There are several original studies about antibiotic prescribing in the healthcare setting of Iran reporting different levels of prescribing. The aim of this systematic review and meta-analysis was to determine the prevalence of antibiotic prescribing in both inpatient and outpatient settings in Iran, an example of a developing country. Methods To identify published studies on antibiotic prescribing, databases such as ISI, Scopus, PubMed, Google Scholar, and Electronic Persian were searched in Iran till January 2020. Eligible studies were those analyzing original data on the prescription and use of antibiotics in outpatient or inpatient settings in Iran. Moreover, all studies that used an intervention to improve antibiotic prescribing were included. The quality of the included studies was assessed using self-administered quality assessment criteria. The meta-analysis of prevalence of antibiotic prescribing was conducted based on the meta-analysis of observational studies in epidemiology guidelines. To calculate pooled rates, the random-effects model was used. Results A total of 54 studies (39 outpatients and 15 inpatients) were included in this study. The median of antibiotic prescribing in the outpatient and inpatient settings accounted for 45.25% and 68.2% of patients, respectively. The results of meta-analysis also showed that the antibiotic prescribing accounted for 45% of prescriptions in outpatient settings and 39.5%, 66%, and 75.3% of patients in all wards, pediatrics wards, and ICU wards of inpatient settings, respectively. The most commonly prescribed antibiotic classes in outpatient settings were penicillins, cephalosporins, and macrolides, while in inpatient settings, these were cephalosporins, penicillins, and carbapenems. There were seven studies using interventions to improve antibiotic prescribing pattern. It should be mentioned that intervention in a study had a statistically significant effect on improving antibiotic prescribing (p < .05). Conclusion Prevalence of antibiotic prescribing in Iran is high. Our findings highlight the need for urgent action to improve prescription practices. It seems that developing a national plan to improve antibiotic prescribing is necessary.

Abstract
Our study focuses on the antimicrobial susceptibility, genotypic and phenotypic heterogeneity, and serotype classification of the Streptococcus mutans isolated from type II diabetic patients (n = 25; age 42-68). Eighty-two percent of isolates were classified as serotype c. No serotype k was present. Macrorestriction analysis of genomic DNA of the isolates exhibited a clonal diversity that paralleled the phenotypic heterogeneity, which was also assessed in terms of biofilm forming ability. Isolates were susceptible to all the classes of antibiotics. In conclusion a great heterogeneity and no antimicrobial resistance were apparent in the considered S. mutans strains from diabetic patients.

Abstract
OBJECTIVES We examined the real-world treatment of urinary tract infections (UTIs) in a type 2 diabetes mellitus (T2DM) population, evaluated UTI-related healthcare resource use and direct treatment costs, and assessed factors that may predict UTI-related costs. METHODS We analyzed an anonymized dataset from a regional German healthcare fund (2010-2012). UTI-associated resource use was described by the number of UTI-associated outpatient visits, the number and length of UTI-related acute hospital visits, and the number of UTI-related antibiotics prescriptions. UTI-related direct treatment costs were studied both based on these resource use numbers and, additionally, based on a comparison of all-cause annual healthcare costs of T2DM-patients who were or were not affected by a UTI. To identify factors that might predict direct treatment costs related to UTI treatment, we conducted generalized linear regression model analyses (based on gamma distribution) using sociodemographic and clinical characteristics of observed patients as available in the database as independent variables. RESULTS A total of 456,586 T2DM-patients were included with a mean age of 73.8, a percentage of 56.3 female patients, and a mean Charlson comorbidity index of 7.3. In our database, we observed 48,337 UTI events. The direct mean resource-based costs were €315.90 per UTI event. Older age, higher comorbidity status, at least one previous non-UTI infection, and poorer renal function were associated with higher costs, while female gender and at least one previous UTI event were associated with lower costs. In the all-cause cost analysis, healthcare costs per patient year were €3,916 higher in the UTI group than in the non-UTI group. CONCLUSION Our study confirms that UTI is a common complication in patients with T2DM. Patients with T2DM who have had previous infections, who are older, and who are male, as well as patients who have more comorbidities or severe renal insufficiency, face above-average UTI treatment costs. These patient groups, therefore, should receive special attention in the real-world treatment of T2DM, which should include a regular screening of UTI risk.

Abstract
INTRODUCTION This analysis was conducted to investigate urinary tract infection (UTI) incidence among Type 2 Diabetes mellitus (T2DM) patients in Germany in a real-world setting and to identify risk factors associated with UTI incidence/recurrence. METHODS Our cohort study was conducted based on an anonymized dataset from a regional German sickness fund (2010-2012). A UTI event was mainly identified through observed outpatient/inpatient UTI diagnoses. We reported the number of UTI events per 1000 patient-years. Furthermore, the proportion of patients affected by ≥1 and ≥2 UTI events in the observational period was separately reported. Finally, three multivariate Cox regression analyses were conducted to identify factors that may be associated with UTI event risk or recurrent UTI event risk. RESULTS A total of 456,586 T2DM-prevalent patients were identified (mean age 72.8years, 56.1% female, mean Charlson Comorbidity Index (CCI) of 7.3). Overall, the UTI event rate was 87.3 events per 1000 patient-years (111.8/55.8 per 1000 patient-years for women/men (p<0.001)). The highest UTI event rates were observed for those aged >89years. After 730days after first observed T2DM diagnosis, the proportion of women/men still UTI-event-free was 80.9%/90.2% (p<0.001). Most important factors associated with UTI risk in our three models were older age (Hazard Ratio (HR)=1.56-1.70 for >79years), female gender (HR=1.38-1.57), UTIs in the previous two years (HR=2.77-5.94), number of comorbidities as measured by the CCI (HR=1.32-1.52 for CCI>6) and at least one cystoscopy in the previous year (HR=2.06-5.48). Furthermore, high HbA1c values in the previous year (HR=1.29-1.4 referring to HbA1c>9.5%) and a poor kidney function (HR=1.11-1.211 referring to glomerular filtration rate (GFR)<60ml/min) increased the UTI event risk. DISCUSSION Our study confirms that UTI event risk is high in T2DM patients. Older female patients having experienced previous UTIs face an above-average UTI risk, especially if these risk factors are associated with poor glycemic control and poor kidney function.

Abstract
Urinary tract infections are more common, more severe, and carry worse outcomes in patients with type 2 diabetes mellitus. They are also more often caused by resistant pathogens. Various impairments in the immune system, poor metabolic control, and incomplete bladder emptying due to autonomic neuropathy may all contribute to the enhanced risk of urinary tract infections in these patients. The new anti-diabetic sodium glucose cotransporter 2 inhibitors have not been found to significantly increase the risk of symptomatic urinary tract infections. Symptoms of urinary tract infection are similar to patients without diabetes, though some patients with diabetic neuropathy may have altered clinical signs. Treatment depends on several factors, including: presence of symptoms, severity of systemic symptoms, if infection is localized in the bladder or also involves the kidney, presence of urologic abnormalities, accompanying metabolic alterations, and renal function. There is no indication to treat diabetic patients with asymptomatic bacteriuria. Further studies are needed to improve the treatment of patients with type 2 diabetes and urinary tract infections.

Abstract
New-onset diabetes mellitus after kidney transplantation (NODAT) is widely acknowledged to be associated with increased morbidity and mortality, as well as poor quality of life. Clear evidence links the occurrence of NODAT to accelerated progression of some macrovascular and/or microvascular complications. However, the evidence that some complications commonly attributed to diabetes mellitus occur in the context of transplantation lacks robustness. Certain complications are transplantation-specific and prevalent, but others are not frequently observed or documented. For this reason, it is essential that clinicians are aware of the array of potential complications associated with NODAT in kidney allograft recipients. Rather than simply translating evidence from the general population to the high-risk transplant recipient, this Review aims to provide specific guidance on diabetes-related complications in the context of a complex transplantation environment.

Abstract
The burden of respiratory infections is mainly seen in primary healthcare. To evaluate the potential impact of new preventive strategies against respiratory infections, such as the implementation of pneumococcal conjugate vaccines for infants in 2006 in The Netherlands, we conducted a baseline retrospective cohort study of electronic primary-care patient records to assess consultation rates, comorbidities and antibiotic prescription rates for respiratory infections in primary care. We found that between 1995 and 2005, overall registered consultation rates for lower respiratory tract infections had increased by 42·4%, upper respiratory infections declined by 4·9%, and otitis media remained unchanged. Concomitantly, there was a steady rise in overall comorbidity (75·7%) and antibiotic prescription rates (67·7%). Since Dutch primary-care rates for respiratory infections changed considerably between 1995 and 2005, these changes must be taken into account to properly evaluate the effect of population-based preventive strategies on primary-care utilization.
