Rifampin Based Therapy for Patients With Staphylococcus aureus Native Vertebral Osteomyelitis: A Systematic Review and Meta-analysis.

BACKGROUND: Native vertebral osteomyelitis (NVO) caused by Staphylococcus aureus is associated with high risk of treatment failure and increased morbidity. The role of rifampin-based therapy for the treatment of this condition is controversial. The goal of this systematic review and meta-analysis is to explore the efficacy and safety of rifampin-based therapy for the treatment of S. aureus NVO. METHODS: We searched Cochrane, Embase, Medline, Scopus, and Web of Science databases for studies published up to May 2023, focusing on adults with NVO treated with or without rifampin-containing regimens. A random-effects model meta-analysis estimated relative risks and risk difference with 95% confidence intervals (CI). RESULTS: Thirteen studies (2 randomized controlled trials and 11 comparative cohort studies), comprising 244 patients with S. aureus NVO who received rifampin and 435 who did not, were analyzed. Meta-analysis showed that rifampin-based regimens were associated with lower risk of clinical failure (risk difference, -14%; 95% CI, -19% to -8%; P < .001; I2 = 0%; relative risk, 0.58; 95% CI, .37-.92, P = .02, I2 = 21%). Only 1 study reported on adverse events. All studies had a high or uncertain risk of bias, and the certainty of evidence was rated as very low. CONCLUSIONS: Adjunctive rifampin therapy might be associated with lower risk of S. aureus NVO treatment failure; however, the low certainty of evidence precludes drawing definitive conclusions that would alter clinical practice. A randomized trial is necessary to corroborate these findings.

Effect of Preoperative Antibiotic Therapy on Operative Culture Yield for Diagnosis of Native Joint Septic Arthritis.

BACKGROUND: Native joint septic arthritis (NJSA) is definitively diagnosed by a positive Gram stain or culture, along with supportive clinical findings. Preoperative antibiotics are known to alter synovial fluid cell count, Gram stain, and culture results and are typically postponed until after arthrocentesis to optimize diagnostic accuracy. However, data on the impact of preoperative antibiotics on operative culture yield for NJSA diagnosis are limited. METHODS: We retrospectively reviewed adult cases of NJSA who underwent surgery at Mayo Clinic facilities from 2012 to 2021 to analyze the effect of preoperative antibiotics on operative culture yield through a paired analysis of preoperative culture (POC) and operative culture (OC) results using logistic regression and generalized estimating equations. RESULTS: Two hundred ninety-nine patients with NJSA affecting 321 joints were included. Among those receiving preoperative antibiotics, yield significantly decreased from 68.0% at POC to 57.1% at OC (P < .001). In contrast, for patients without preoperative antibiotics there was a non-significant increase in yield from 60.9% at POC to 67.4% at OC (P = .244). In a logistic regression model for paired data, preoperative antibiotic exposure was more likely to decrease OC yield compared to non-exposure (odds ratio [OR] = 2.12; 95% confidence interval [CI] = 1.24-3.64; P = .006). Within the preoperative antibiotic group, additional antibiotic doses and earlier antibiotic initiation were associated with lower OC yield. CONCLUSIONS: In patients with NJSA, preoperative antibiotic exposure resulted in a significant decrease in microbiologic yield of operative cultures as compared to patients in whom antibiotic therapy was held prior to obtaining operative cultures.

Nontuberculous mycobacterial infections in patients with hematologic malignancies and recipients of hematopoietic stem cell transplantation.

BACKGROUND: The incidence of mycobacterial infections in patients with hematologic malignancies and hematopoietic stem cell transplant (HSCT) recipients is increasing, contributing to significant mortality and morbidity. This review explores the epidemiology, risk factors, clinical presentation, diagnosis, and treatment of nontuberculous mycobacteria (NTM) in this population. METHODS: A literature search was performed using PubMed with keywords and MeSH terms pertaining to the topics of nontuberculous mycobacteria, hematologic malignancies, hematopoietic stem cell transplant, cellular therapies, chimeric antigen therapies, epidemiology, diagnosis, and treatment. Additionally, we examined the reference lists of the included articles to identify other pertinent studies. RESULTS: Diagnosing mycobacterial disease among patients with hematologic disease and treatment-associated immunosuppressive conditions is challenging due to the lack of distinctive clinical, radiographic, and laboratory markers, as well as the atypical manifestations compared to immunocompetent patients. Treatment involves using a combination of antibiotics for extended durations, coupled with strategies to achieve source control and reduce immunosuppression when feasible. This is complicated by the absence of clear data correlating in-vitro drug susceptibility and clinical outcome for many antimicrobials use to treat NTM, adverse drug-drug interactions, and the frequent challenges related to poor medication tolerability and toxicities. CONCLUSION: The rising incidence and corresponding clinical challenges of mycobacterial infections in this unique patient population necessitate a heightened awareness and familiarity of NTM disease by clinicians to achieve timely diagnosis and favorable treatment outcomes.

Tiny but Nasty: A case report and a review of the literature on Ureaplasma parvum peritonitis.

Ureaplasma parvum, a member of the Mollicutes class, is a rare but significant pathogen in extragenital infections. This case report is the tenth known case of Ureaplasma spp. peritonitis, occurring in a 36-year-old female post extensive surgery for metastatic sigmoid colon adenocarcinoma. Following the intervention, the patient exhibited post-surgical peritonitis with fever despite empirical broad-spectrum antibiotics. Conventional bacterial and fungal cultures remained negative, prompting the use of 16 S rRNA polymerase chain reaction (PCR) for diagnosis. Ureaplasma parvum was detected in both peritoneal and perihepatic fluid samples, and in the urine, leading to the initiation of doxycycline therapy. The patient responded positively to the treatment, with complete resolution of symptoms and no recurrence observed during a four-year follow-up. This report underscores the clinical challenge posed by Ureaplasma spp. due to its resistance to common antibiotics and difficulty in cultivation. It highlights the importance of molecular diagnostics in identifying such pathogens in culture-negative cases and the necessity of considering Ureaplasma spp. especially in female patients with persistent peritonitis post-urogenital procedures or surgeries. The case also reflects on the limited data regarding antimicrobial susceptibility, emphasizing the need for tailored therapeutic approaches based on local resistance patterns and the clinical context. Ultimately, this case contributes valuable insights into the diagnosis and management of Ureaplasma spp. peritonitis, advocating for heightened clinical suspicion and appropriate molecular testing to ensure effective patient outcomes.

Culture-Negative Native Vertebral Osteomyelitis: A Narrative Review of an Underdescribed Condition.

The incidence of culture-negative NVO (CN-NVO) cases is increasing, presenting significant diagnostic and therapeutic challenges due to the inability to isolate causative organisms with conventional microbiological methods. Factors influencing the diagnosis of CN-NVO include prior antimicrobial therapy, low pathogen burden, fastidious or intracellular organisms, technical issues, and non-infectious mimickers. Diagnosis often relies on imaging modalities like magnetic resonance imaging (MRI) and computed tomography (CT)-guided biopsy, though these methods can sometimes fail to yield positive microbiological results. Advanced diagnostic tools, such as polymerase chain reaction (PCR), metagenomic next-generation sequencing (mNGS), and cell-free DNA analysis, may be necessary to identify the pathogen. The causative pathogen cannot be isolated in some patients, among which an empirical antimicrobial therapy should be initiated. This narrative review discusses the management, monitoring, surgical indications, and outcomes for patients with CN-NVO.

Optimal antibiotics duration following surgical management of septic olecranon bursitis: a 12-year retrospective analysis.

Introduction: The absence of a standardized postoperative antibiotic treatment approach for patients with surgically treated septic bursitis results in disparate practices. Methods: We retrospectively reviewed charts of adult patients with surgically treated septic olecranon bursitis at Mayo Clinic sites between 1 January 2000 and 20 August 2022, focusing on their clinical presentation, diagnostics, management, postoperative antibiotic use, and outcomes. Results: A total of 91 surgically treated patients were identified during the study period. Staphylococcus aureus was the most common pathogen (64 %). Following surgery, 92 % (84 of 91 patients) received systemic antibiotics. Excluding initial presentations of bacteremia or osteomyelitis (n=5), the median duration of postoperative antibiotics was 21 d (interquartile range, IQR: 14-29). Postoperative complications were observed in 23 % (21 of 91) of patients, while cure was achieved in 87 % (79 of 91). Active smokers had 4.53 times greater odds of clinical failure compared with nonsmokers (95 % confidence interval, 95 % CI: 1.04-20.50; p=0.026). The highest odds of clinical failure were noted in cases without postoperative antibiotic administration (odds ratio, OR: 7.4). Conversely, each additional day of antibiotic treatment, up to 21 d, was associated with a progressive decrease in the odds of clinical failure (OR: 1 at 21 d). Conclusion: The optimal duration of antibiotics postoperatively in this study was 21 d, which was associated with a 7.4-fold reduction in the odds clinical failure compared with cases without postoperative antibiotics. Further validation through a randomized controlled trial is needed.

Acute Coxiella burnetii Infection: A 10-Year Clinical Experience at a Tertiary Care Center in the United States.

Background: Identifying and treating patients with acute Q fever who are at an increased risk of progressing to persistent disease is crucial for preventing future complications. In this study, we share our decade-long clinical experience with acute Q fever, highlighting the challenges that clinicians encounter from making an initial diagnosis and performing risk stratification to determining the appropriate prophylaxis regimen and duration. Methods: We retrieved records of adult Mayo Clinic patients (≥18 years) with positive Coxiella burnetii serology results between 1 January 2012 and 31 March 2022. Patients with Q fever anti-phase II immunoglobulin G ≥1:256 by indirect immunofluorescence were further analyzed. Results: Thirty-one patients were included. Their median age was 58 years (IQR, 50-64), and the majority were men (84%). Acute hepatitis (29%), flu-like illness (25.8%), and pneumonia (16%) were the most common presentations. Thirteen patients (42%) received antibiotic prophylaxis to prevent disease progression, with significant variation in the indications and duration across physicians. The combination of doxycycline and hydroxychloroquine was the preferred regimen. Prophylaxis was administered for a median 333 days (IQR, 168-414). Four patients (13%) progressed to Q fever native valve infective endocarditis, with elevated anticardiolipin immunoglobulin G levels being the sole risk factor in 2 cases. The small sample size precluded drawing conclusions on the impact of prophylaxis in preventing disease progression. Conclusions: Management of acute Q fever is complicated by the lack of comprehensive clinical guidelines leading to varied clinical practices. There is a critical need for randomized trials to establish robust evidence-based protocols for management.

It is time for a unified definition of native vertebral osteomyelitis: a framework proposal.

In recent years, there has been a notable increase in research output on native vertebral osteomyelitis (NVO), coinciding with a rise in its incidence. However, clinical outcomes remain poor, due to frequent relapse and long-term sequelae. Additionally, the lack of a standardized definition and the use of various synonyms to describe this condition further complicate the clinical understanding and management of NVO. We propose a new framework to integrate the primary diagnostic tools at our disposal. These collectively fall into three main domains: clinical, radiological, and direct evidence. Moreover, they and can be divided into seven main categories: (a) clinical features, (b) inflammatory biomarkers, (c) imaging techniques, microbiologic evidence from (d) blood cultures and (e) invasive techniques, (f) histopathology, and (g) empirical evidence of improvement following the initiation of antimicrobial therapy. We provide a review on the evolution of these techniques, explaining why no single method is intrinsically sufficient to formulate an NVO diagnosis. Therefore, we argue for a consensus-driven, multi-domain approach to establish a comprehensive and universally accepted definition of NVO to enhance research comparability, reproducibility, and epidemiological tracking. Ongoing research effort is needed to refine these criteria further, emphasizing collaboration among experts through a Delphi method to achieve a standardized definition. This effort aims to streamline research, expedite accurate diagnoses, optimize diagnostic tools, and guide patient care effectively.

Plasma Microbial Cell-free DNA Next-generation Sequencing Can Be a Useful Diagnostic Tool in Patients With Osteoarticular Infections.

Background: Recent advances in shotgun metagenomic sequencing (sMGS) for detecting microbial cell-free DNA (mcfDNA) in peripheral blood have shown promise across various patient populations. This study evaluates the application of sMGS for diagnosing osteoarticular infections (OAIs), a condition with significant diagnostic challenges. Methods: We conducted a retrospective analysis on 73 patients suspected of OAIs at the Mayo Clinic from 2019 to 2023, incorporating mcfDNA sMGS (Karius test [KT]) into their diagnostic evaluation. We categorized the clinical impact of KT on OAI diagnoses and management into 4 distinct outcomes. (1) KT was able to confirm an established diagnosis, (2) KT supported noninfectious diseases diagnosis, (3) KT established an unsuspected diagnosis, (4) KT did not add relevant information. Results: In our cohort, KT was performed in 73 patients. Among the infected individuals, KT yielded positive results in 22 of 43 (51.2%) cases. Of these 22 cases, 11 (50%) showed agreement with conventional diagnostic workup, whereas in 5 (22.7%) cases, the KT established an unsuspected diagnosis. Native vertebral osteomyelitis diagnosis (P < .001) or OAIs with concomitant presence of endocarditis or endovascular infection (P = .005) were statistically associated with a definite, probable, or possible diagnostic certainty of KT result. Conclusions: In complex OAIs, KT enhanced diagnostic accuracy by 11.6%, proving especially beneficial in diagnosing native vertebral osteomyelitis and infections with concurrent endocarditis or endovascular complications. Our findings underscore the utility of KT in the diagnostic workflow for challenging OAI cases, potentially altering clinical management for a significant subset of patients.

Effect of Antibiotic Therapy Before Arthrocentesis on Synovial Fluid Cell Count and Differential for Diagnosis of Native Joint Septic Arthritis.

We examined the effect of preoperative antibiotic exposure and duration on synovial fluid samples from patients with native joint septic arthritis of the hip/knee. While exposure before diagnostic arthrocentesis did not affect fluid parameters, increased duration was associated with a decreased total nucleated cell count, underscoring the complex antibiotic effects on synovial fluid parameters.

Native joint polyarticular septic arthritis secondary to disseminated Ureaplasma urealyticum infection in a patient on rituximab therapy with hypogammaglobulinemia: A Case Report.

Ureaplasma urealyticum and Ureaplasma parvum are important causes of septic arthritis in patients with hypogammaglobulinemia. The diagnosis can be challenging, leading to prolonged illness and increased morbidity, and mortality. This is driven by the complex growth media requirements of Ureaplasma species and the difficulty in identifying the organisms on routine culture media. Herein, we present a case of native joint polyarticular septic arthritis and vertebral infection secondary to disseminated U. urealyticum in a patient maintained on rituximab. The diagnosis was established through a positive species-specific U. urealyticum polymerase chain reaction (PCR) after a meticulous workup including synovial fluid biopsy, cultures and broad-range bacterial PCR returned negative. Septic arthritis caused by Ureaplasma species should be considered in the differential diagnosis especially in immunocompromised patients with hypogammaglobulinemia, even if the initial microbiological workup is non-revealing. Delayed diagnosis and treatment are associated with increased morbidity.

Clinical manifestations, treatment and outcomes of patients infected with Mycobacterium haemophilum with a focus on immune reconstitution inflammatory syndrome: a retrospective multi-site study.

BACKGROUND: Mycobacterium haemophilum is a nontuberculous mycobacterium with fastidious in vitro growth requirements and an increasingly reported cause of extrapulmonary disease. Timely diagnosis and management of M. haemophilum infections and the immune reconstitution inflammatory syndromes (IRIS) observed in a subset of patients during treatment remain challenging. METHODS: We conducted a retrospective chart review between January 1, 2010, and January 1, 2022 and identified 26 patients diagnosed with M. haemophilum infection at our institution. We describe their clinical presentation, diagnostic results, management, and outcomes. RESULTS: The majority of patients in our cohort had upper and/or lower extremity skin involvement, were immunosuppressed, and had generally favourable treatment outcomes. All tested M. haemophilum isolates were susceptible in vitro to clarithromycin and trimethoprim-sulfamethoxazole. Moreover, high rates of susceptibility were noted for ciprofloxacin (95%), linezolid (90%), and rifampin (85%). IRIS was identified in 31% of cases and should be considered in patients who develop worsening skin lesions or systemic symptoms following the initiation of effective antimicrobial therapy. Visualisation of acid-fast bacilli on initial tissue stains, a positive mycobacterial blood culture, and rapid de-escalation of tumour necrosis factor-α inhibitors and/or corticosteroids were more frequently encountered among patients in our cohort who developed IRIS. CONCLUSION: M. haemophilum infection should be considered among patients receiving immunomodulatory therapy who develop discoloured or nodular skin lesions involving the extremities, worsening focal arthritis, tenosynovitis, or isolated adenopathy. A heightened awareness of this pathogen's clinical and laboratory characteristics can lead to a timely diagnosis and favourable outcome.

A Review of Hemophagocytic Lymphohistiocytosis in Patients With HIV.

We provide an elaborate review of cases published between January 2005 and April 2021 on hemophagocytic lymphohistiocytosis (HLH) in HIV patients. Seventy articles describing 81 adult patients (age ≥19 years) were included. The median age was 40 years, and 78% were males. Only 65% were known to have HIV before presentation. CD4 count was ≥200 cells/mm3 in 23%, and HIV viral load was <200 copies/mL in 41%. The lack of meticulous reporting of ≥5 of 8 criteria for HLH diagnosis was evident in a third of cases. At least 1 infectious agent-other than HIV-was believed to trigger HLH in 78% of patients. The most common were Epstein-Barr virus (26%), human herpesvirus 8 (21%), and Histoplasma capsulatum (17%). Sixty percent survived. Among those, 93% received treatment for identified secondary trigger(s), while 51% received HLH-directed therapy. There was significant heterogeneity in the treatment regimens used for HLH.

Contemporary demographics, diagnostics and outcomes in non-bacterial thrombotic endocarditis.

OBJECTIVE: Non-bacterial thrombotic endocarditis (NBTE) is a syndrome characterised by cardiac valve vegetations and/or thickening due to non-infective mechanisms. Nowadays, a premortem diagnosis of NBTE is possible based on echocardiographic findings. Therefore, to better characterise this disease, we performed a contemporary review of the epidemiology, demographics, diagnosis and clinical outcomes of these patients. METHODS: Adults with a diagnosis of NBTE seen within the Mayo Clinic Enterprise from December 2014 to December 2021 were included. NBTE diagnosis was identified by clinicians representing at least two specialties including cardiology, infectious diseases, rheumatology and oncology. Patients with positive blood cultures, infective endocarditis, culture-negative endocarditis and denial of research authorisation were excluded. All patients had a 1-year follow-up. RESULTS: Forty-eight cases were identified; mean age was 60.0±13.8 years, 75% were female. The most prevalent comorbidities were malignancy (52.1%) and connective tissue disease (37.5%). Valvular abnormalities included 41 (85.4%) patients with vegetations, 43 (89.6%) patients with thickening and 26 (54.2%) with moderate to severe regurgitation. Thirty-eight (79.2%) patients had an embolic event (stroke in 26 (54.2%) patients) within 1 month of NBTE diagnosis and 16 (33.3%) patients died within 1 year of NBTE diagnosis. Metastatic tumours and lung cancer were associated with 1-year all-cause mortality (p=0.0017 and p=0.0004, respectively). CONCLUSIONS: NBTE was more prevalent in females and embolic complications were the most frequent clinical finding. Overall, patients with NBTE had a poor prognosis, particularly in those with lung cancer or metastatic tumours. Further studies in patients with NBTE are needed given its morbidity and mortality.

SARS-CoV-2 infection: Initial viral load (iVL) predicts severity of illness/outcome, and declining trend of iVL in hospitalized patients corresponds with slowing of the pandemic.

BACKGROUND: Hospitalization of patients infected with the severe acute respiratory syndrome virus 2 (SARS-CoV-2) have remained considerable worldwide. Patients often develop severe complications and have high mortality rates. The cycle threshold (Ct) value derived from nasopharyngeal swab samples using real time polymerase chain reaction (RT-PCR) may be a useful prognostic marker in hospitalized patients with SARS-CoV-2 infection, however, its role in predicting the course of the pandemic has not been evaluated thus far. METHODS: We conducted a retrospective cohort study which included all patients who had a nasopharyngeal sample positive for SARS-CoV-2 between April 4 -June 5, 2020. The Ct value was used to estimate the number of viral particles in a patient sample. The trend in initial viral load on admission on a population level was evaluated. Moreover, patient characteristics and outcomes stratified by viral load categories were compared and initial viral load was assessed as an independent predictor of intubation and in-hospital mortality. RESULTS: A total of 461 hospitalized patients met the inclusion criteria. This study consisted predominantly of acutely infected patients with a median of 4 days since symptom onset to PCR. As the severity of the pandemic eased, there was an increase in the percentage of samples in the low initial viral load category, coinciding with a decrease in deaths. Compared to an initial low viral load, a high initial viral load was an independent predictor of in-hospital mortality (OR 5.5, CI 3.1-9.7, p < 0.001) and intubation (OR 1.82 CI 1.07-3.11, p = 0.03), while an initial intermediate viral load was associated with increased risk of inpatient mortality (OR 1.9, CI 1.14-3.21, p = 0.015) but not with increased risk for intubation. CONCLUSION: The Ct value obtained from nasopharyngeal samples of hospitalized patients on admission may serve as a prognostic marker at an individual level and may help predict the course of the pandemic when evaluated at a population level.

SARS-CoV-2 Viral Load and Myocardial Injury: Independent and Incremental Predictors of Adverse Outcome.

To evaluate the association of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) initial viral load (iVL) and the incidence of myocardial injury (MCI) in hospitalized patients with SARS-CoV-2 infection, we conducted a retrospective longitudinal study of hospitalized patients who had a nasopharyngeal swab sample on admission that returned a positive result for SARS-CoV-2 by polymerase chain reaction between April 4 and June 5, 2020. The cycle threshold (Ct) value was used as a surrogate for the iVL level, with a Ct level of 36 or less for elevated iVL and greater than 36 for low iVL. Myocardial injury was defined as an elevated high-sensitivity cardiac troponin I level that was higher than the 99th percentile upper reference limit. A total of 270 patients were included. Of these, 171 (63.3%) had an elevated iVL and 88 (32.6%) had MCI. There was no significant difference in the incidence of MCI in patients with low iVL compared to those with elevated iVL (28 of 99 [28.3%] vs 60 of 171 [35.1%]; P=.25). In a multivariable model, MCI (odds ratio, 3.86; 95% CI, 1.80 to 8.34; P<.001) and elevated iVL (odds ratio, 4.21; 95% CI, 2.06 to 8.61; P<.001) were independent and incremental predictors of in-hospital mortality. The SARS-CoV-2 iVL level is not associated with increased incidence of MCI, although both parameters are strong independent and incremental predictors of mortality. Understanding the MCI mechanisms allows for early focused interventions to improve survival, especially in patients with SARS-CoV-2 infection and high iVL.

Invasive Saprochaete Infections: An Emerging Threat to Immunocompromised Patients.

Saprochaete clavata and Saprochaete capitata are emerging fungal pathogens that are responsible for life threatening infections in immunocompromised patients, particularly in the setting of profound neutropenia. They have been associated with multiple hospital outbreaks mainly in Europe. In this article, we present a comprehensive review of the epidemiology, clinical presentation, diagnosis, antifungal susceptibility and treatment of these organisms. The diagnosis of invasive Saprochaete disease is challenging and relies primarily on the isolation of the fungi from blood or tissue samples. Both species are frequently misidentified as they are identical macroscopically and microscopically. Internal transcribed spacer sequencing and matrix-assisted laser desorption ionization-time of flight mass spectrometry are useful tools for the differentiation of these fungi to a species level. Saprochaete spp. are intrinsically resistant to echinocandins and highly resistant to fluconazole. Current literature suggests the use of an amphotericin B formulation with or without flucytosine for the initial treatment of these infections. Treatment with extended spectrum azoles might be promising based on in vitro minimum inhibitory concentration values and results from case reports and case series. Source control and recovery of the immune system are crucial for successful therapy.

Prevalence of infections and antimicrobial use in the acute-care hospital setting in the Middle East: Results from the first point-prevalence survey in the region.

OBJECTIVES: Community-acquired (CAIs) and healthcare-associated (HAIs) infections are associated with significant morbidity and mortality. Data related to the epidemiology of these infections in the Middle East is scarce. The aim of this study is to estimate the prevalence of infections and antimicrobial use in the acute hospital setting in this region. METHODS: A multicentre Point-Prevalence Survey was conducted in seven Middle Eastern countries: Egypt, Kingdom of Saudi Arabia, United Arab Emirates, Lebanon, Oman, Kuwait and Bahrain. Data were collected by the infection control and infectious diseases teams of the respective hospitals. Study surveys were completed in one day (03 April 2018). RESULTS: The overall point prevalence of infection was 28.3%; HAI and CAI point prevalence was 11.2% and 16.8%, respectively. The majority of patients with an infection (98.2%) were receiving antimicrobial therapy. There were high levels of resistance to antimicrobials among Acinetobacter baumannii, Enterobacter cloacae, Klebsiella pneumoniae and other Klebsiella sp. CONCLUSIONS: Our findings indicate that the point prevalence of both HAI and CAI is high in a sample of Middle Eastern countries. These findings along with the increased use of antimicrobials represent a significant public health problem in the region; particularly in light of the growing regional antimicrobial resistance.
