Point-of-care ultrasound in infectious diseases: Current insights and future perspectives.

Point-of-Care Ultrasound (POCUS) is a safe, non-invasive technique performed at the patient's bedside, providing immediate results to the operator. It complements physical examination and facilitates clinical decision-making. In infectious diseases, POCUS is particularly valuable, offering an initial assessment in cases of suspected infection. It often leads to an early tentative diagnosis enabling the prompt initiation of antimicrobial treatment without the delay associated with traditional radiology. POCUS provides direct visualization of affected organs, assists in evaluating fluid balance and facilitates various interventions, all while reducing patient discomfort. For infectious disease specialists, becoming proficient in POCUS is a critical future challenge, requiring dedicated training for effective utilization.

Infective Native Aortic Aneurysm: a Delphi Consensus Document on Treatment, Follow Up, and Definition of Cure

Abstract Background Evidence is lacking to guide the management of infective native aortic aneurysm (INAA). Aims The aim of this study was to establish expert consensus on surgical and antimicrobial treatment and follow up, and to define when an INAA is considered cured. Methods Delphi methodology was used. The principal investigators invited 47 international experts (specialists in infectious diseases, radiology, nuclear medicine, and vascular and cardiothoracic surgery) via email. Four Delphi rounds were performed, 3 weeks each, using an online questionnaire with initially 28 statements. The panelists rated the statements on a 5-point Likert scale. Comments on statements were analysed, statements were revised and added or deleted, and the results were presented in the iterative rounds. Consensus was defined as ≥ 75% of the panel rating a statement as strongly agree or agree on the Likert scale, and consensus on the final assessment was defined as Cronbach’s α > 0.80. Results All 49 panelists fulfilled all four rounds, resulting in 100% participation. One statement was added based on the results and comments of the panel, resulting in 29 final statements: n = 3 on need for consensus, n = 20 on treatment, n = 5 on follow up, and n = 1 on definition of cure. All 29 statements reached agreement of ≥ 86%. Cronbach’s α increased for each consecutive round; round 1, 0.85; round 2, 0.90; round 3, 0.91; and round 4, 0.94. Thus, consensus was reached for all statements. Conclusion INAA is rare, and high-level evidence is lacking to guide optimal management. This consensus document was established with the aim of helping clinicians manage these challenging patients, as a supplement to current guidelines. The presented consensus will need future amendments in accordance with newly acquired knowledge.

ENDOCARDITIS TEAM? DESIGNING AN ORIGINAL AND TAILORED CLINICAL PATHWAY

Abstract Infective endocarditis (IE) remains a poorly understood disease that primarily affects either native or prosthetic heart valves. Its incidence has increased over the past two decades, now affecting 3 to 10 individuals per 100.000/year in the general population. Despite advances in early diagnosis and surgical intervention, IE continues to pose a significant challenge, often leading to severe complications and carrying a substantial burden of morbidity and mortality. Data from the EURO–Endo registry show a drastic change in IE and provide an accurate picture of IE disease today. In European countries, it tends to affect older patients with a remarkable 12% of cases occurring in those aged ≥ 80 years. The traditional care pathway is often fragmented into multiple and potentially dangerous steps, resulting in delayed diagnosis and treatment. Such a “patchy” approach may cause suboptimal patient management, especially in the subset of frail patients with important concomitant diseases and high surgical risk. Clinical pathways (CPs) are an evidence–based multidisciplinary care plans involving diagnosis, treatment and rehabilitation phases, through which to follow patients from hospital admission to discharge, in order to manage a specific health condition, aiming to optimize patient and hospital/team outcomes, while contributing to a better organized care processes. In 2018, a working group composed by healthcare managers, infectious disease specialists, cardiac surgeons, cardiologists, anesthesiologists, geriatricians and other professionals involved in the care of IE patients have engineered a dedicated CP for IE at our institution. The CP introduced significant changes in the management of patients with IE. As a result, the quality of care and services offered increased, a faster and more appropriate diagnosis and treatment were achieved, patient outcomes and safety improved and a better coordination and continuity of care between different settings was guaranteed. The growing burden of IE in western countries demands an evidence–based multidisciplinary care plan. The creation of a territorial network ensures continuity and appropriateness of care in conjunction with the referring physicians/hospital and rationalization of resources. Although some controversies still exist, we believe that CP will have a positive impact on quality in health care.

PROSTHETIC GRAFT INFECTION: WHEN ECHOCARDIOGRAPHY IS NOT ENOUGH!

Abstract A 68–year–old Caucasian male, post–Bentall procedure with a bioprosthetic valve following extensive aortic dissection involving the ascending aorta and aortic arch, presented to the Emergency Department with persistent fever for over a month. During his hospitalization, he experienced ventricular fibrillation in the setting of hypokalemia, successfully managed with Advanced Cardiovascular Life Support (ACLS) and DC shock, leading to the restoration of sinus rhythm. Subsequently, he was admitted to the Cardiovascular Intensive Care Unite. Blood tests revealed neutrophilic leukocytosis with elevated inflammatory markers, anemia, and a troponin curve consistent with myocardial injury in the context of sepsis and anemia. Echocardiography demonstrated a left ventricle of normal dimensions with globally depressed function (EF 45%), attributed to apical akinesia. The prosthetic valve was functioning normally, and there were no signs of endocarditic vegetations or pericardial involvement. A transesophageal echocardiogram confirmed the absence of vegetations. Given echocardiographic signs of myocardial ischemia, coronary angiography was performed, revealing a coronary circulation free from significant stenosis. Cultural exams showed positivity for Enterococcus faecalis. A PET–CT revealed the presence of radioisotope uptake around the vascular prosthesis situated in the aortic arch. An Infectious Disease specialist recommended antibiotic therapy with Piperacillin/Tazobactam and Teicoplanin. At the one–month follow–up, the patient remained asymptomatic, free from new febrile episodes. The follow–up echocardiogram indicated improved global systolic function, and inflammatory markers remained consistently negative. Repeat blood cultures were negative. This case illustrates a suspected endocarditis on a prosthetic valve where both transthoraci and transesophageal echocardiography yielded negative results. The use of PET–CT, on the other hand, revealed the presence of vascular graft infection, proving to be a valuable method in this clinical setting.

Variation in North American infectious disease specialists’ practice regarding oral and suppressive antibiotics for adult osteoarticular infections: results of an Emerging Infections Network (EIN) survey

Abstract Background Osteoarticular infections (OAI) are commonly treated with prolonged intravenous (IV) antimicrobials. The Oral versus Intravenous Antibiotics for Bone and Joint Infection (OVIVA) trial demonstrated that oral (PO) antibiotics are noninferior to IV antibiotics in the treatment of OAIs. We surveyed Infectious disease (ID) physicians about their use of PO antibiotics in the treatment of OAIs. Methods An Emerging Infection Network (EIN) survey with 9 questions regarding antibiotic prescribing for the treatment of OAIs was sent to 1475 North American ID physicians. The questions were mostly multiple choice and focused on use of definitive oral antibiotic therapy (defined as oral switch within 2 weeks of starting antibiotics) and chronic suppressive antibiotic therapy (SAT). Results Of the 413 physicians who reported treating OAIs, 91% used oral antibiotics at least sometimes and 31% used them as definitive therapy, most often for diabetic foot osteomyelitis and native joint septic arthritis. The oral antibiotics most frequently used for OAIs included trimethoprim-sulfamethoxazole, doxycycline/minocycline, and linezolid for Staphylococcus aureus, amoxicillin/cefadroxil/cephalexin for streptococci, and fluoroquinolones for Gram-negative organisms. The most common rationales for not transitioning to oral antibiotics included non-susceptible pathogen, comorbidities preventing therapeutic drug levels and concerns about adherence. SAT use was variable but employed by a majority in most cases of periprosthetic joint infection managed with debridement and implant retention. Conclusions North American ID physicians utilize oral antibiotics and SAT for the management of OAIs, although significant practice variation exists. Respondents voiced a need for updated guidelines.

Launch of Board Certification in Pediatric Infectious Diseases in Japan.

To cultivate specialists in pediatric infectious diseases (ID) in Japan, the Japanese Society for Pediatric Infectious Diseases initiated board certification for pediatric ID in 2017. Previously, in 2014, we had formed a committee for board certification in pediatric ID and discussed the fundamentals of the board certification system, including the goals, requirements for designated training institutions, provisional certification of pediatric ID specialists and eligibility for and content of the board certification examination. After approval from 31 programs, the pediatric ID programs started in 2017 with 8 fellows in 7 programs. The first 6 graduates received board certification in 2020. To date, 61 pediatricians have been board certified as pediatric ID specialists. In parallel, we introduced board certification for pediatricians who work mainly in primary care settings and have a special interest in pediatric ID. This system has certified 338 pediatricians. During and after the development of the programs, we achieved substantial progress in highlighting the pivotal role of pediatric ID specialists, including the establishment and maintenance of antimicrobial stewardship programs, pediatric ID consultations and introduction of viral diagnosis by polymerase chain reaction at institutions. However, several issues need to be addressed, including the establishment of independent pediatric ID departments in institutions, payment of consultation fees, program site visits, maintenance of certification and cultivation of physician-scientists. These challenges will be the focus of future efforts.

Pre-exposure prophylaxis against HIV infection

Pre-exposure prophylaxis (PrEP) decreases the risk for HIV transmission in high-risk populations. PrEP has been available in Denmark since 2019 and consists of antiretroviral drugs in a combination tablet taken daily or on demand. The effect of this prophylaxis in Denmark is summarized in the review. PrEP is indicated in men and transgender persons with unprotected anal intercourse with multiple male partners in the latest 12 weeks or recent diagnoses of syphilis, chlamydia, or gonorrhoea. PrEP is provided by infectious disease specialists. Continued implementation could significantly reduce HIV transmission and potentially end the epidemic in Denmark.

Exploring European Consensus About the Remaining Treatment Challenges and Subsequent Opportunities to Improve the Management of Invasive Fungal Infection (IFI) in the Intensive Care Unit

BackgroundThe global prevalence of invasive fungal infections (IFI) is increasing, particularly within Intensive Care Units (ICU), where Candida spp. and Aspergillus spp. represent the most important pathogens. Diagnosis and management of IFIs becomes progressively challenging, with increasing antifungal resistance and the emergence of rare fungal species.Through a consensus survey focused on assessing current views on how IFI should be managed, the aim of this project was to identify challenges around diagnosing and managing IFIs in the ICU. The current status in different countries and perceived challenges to date amongst a multidisciplinary cohort of healthcare professionals involved in the care of IFI in the ICU was assessed.MethodsUsing a modified Delphi approach, an expert panel developed 44 Likert-scale statements across 6 key domains concerning patient screening and minimal standards for diagnosis of IFIs in ICU; initiation and termination of antifungal treatments and how to minimise their side effects and insights for future research on this topic. These were used to develop an online survey which was distributed on a convenience sampling basis utilising the subscriber list held by an independent provider (M3 Global). This survey was distributed to intensivists, infectious disease specialists, microbiologists and antimicrobial/ICU pharmacists within the UK, Germany, Spain, France and Italy. The threshold for consensus was set at 75%.ResultsA total of 335 responses were received during the five-month collection period. From these, 29/44 (66%) statements attained very high agreement (≥ 90%), 11/44 (25%) high agreement (< 90% and ≥ 75%), and 4/44 (9%) did not meet threshold for consensus (< 75%). ConclusionThe results outline the need for physicians to be aware of the local incidence of IFI and the associated rate of azole resistance in their ICUs. Where high clinical suspicion exists, treatment should start immediately and prior to receiving the results from any diagnostic test. Beta-D-glucan testing should be available to all ICU centres, with results available within 48 h to inform the cessation of empirical antifungal therapy. These consensus statements and proposed measures may guide future areas for further research to optimise the management of IFIs in the ICU.

Epidemiological and laboratory examination of pregnant women for toxoplasmosis in a polyclinic of the Arkhangelsk region

The article presents the results of examinations of 41 pregnant women by an infectious disease specialist in a clinic for the period from September 22, 2017 to November 19, 2023. The patients were tested for avidity for toxoplasmosis, as well as underwent standard laboratory tests. The results of the epidemic assessment of the situation for each pregnant woman are presented. As a result, it was found that each woman had high-avidity antibodies to toxoplasmosis. These women were not prescribed treatment.

Role of lymphadenopathies in clinical practice of an infectious disease specialist in the Arkhangelsk region

The relevance of the topic under study is due to the wide prevalence of lymphadenopathy (LAP), its various etiology, non-specificity, and an increased risk of neoplastic processes in conditions of environmental distress. Most clinicians of various specialties are familiar with this pathology, including infectious disease specialists, surgeons, GPs, hematologists, oncologists, and pediatricians. Lymphadenopathy is one of the most common clinical symptoms, which complicates differential diagnosis, both between infectious diseases and oncohematological, systemic diseases, tuberculosis, and syphilis. Purpose of the study is to assess the clinical and epidemiological features of lymphadenopathy in various infectious diseases in the Arkhangelsk Region. An analysis of LAP among hospital and clinic patients in the Arkhangelsk Region for the period of 2021–2022 is presented. The following parameters were assessed: prevalence among children and adults, features of the epidemiological history and clinical picture.

Melanoma and basal cell skin cancer in a patient with HIV infection. Clinical observation

The aim is to present the results of the anamnesis, diagnosis and treatment of a case of a combination of malignant melanoma of the skin and basal cell carcinoma of the skin in a patient with HIV infection. Material and methods. The clinical observation of the development of multiple skin lesions with malignant neoplasms (melanoma and basal cell carcinoma) against the background of HIV infection in a patient with low adherence to follow-up and antiretroviral therapy (ART) is described. Clinical and anamnestic data, results of examination and therapy are presented. Results and discussion. Malignant neoplasms of the patient’s skin were first identified by a dermatovenerologist. The patient was routed to an oncologist, fully examined and successfully treated with a combined method (surgical removal of tumors, photodynamic therapy and immunotherapy). Further observation and examination revealed the metastasis of melanoma. The above observation indicates the need for timely and comprehensive examination of people living with HIV (PLHIV) for early detection of oncological diseases. The case demonstrates the possibility of obtaining effective treatment of a malignant neoplasm of the skin against the background of immunosuppression in the short term, despite the patient’s low adherence to therapy. Conclusion. It is especially important for outpatient doctors (infectious disease specialists, dermatovenerologists, surgeons, etc.) to be oncological when working with PLHIV. It is necessary to include malignant neoplasms of the skin, including melanoma and basal cell carcinoma, in the range of differential diagnostic search for erosive ulcerative and nodular lesions. The presented case highlights the need for timely provision of comprehensive medical care and proper routing of comorbid patients.

Ritonavir: 25 Years' Experience of Concomitant Medication Management. A Narrative Review.

Ritonavir is a potent inhibitor of the cytochrome P450 3A4 enzyme and is commonly used as a pharmacokinetic (PK) enhancer in antiviral therapies because it increases bioavailability of concomitantly administered antivirals. Decades of experience with ritonavir-enhanced HIV therapies and, more recently, COVID-19 therapies demonstrate that boosting doses of ritonavir are well tolerated, with an established safety profile. The mechanisms of PK enhancement by ritonavir result in the potential for drug-drug interactions (DDIs) with several classes of drugs, thus making co-medication management an important consideration with enhanced antiviral therapies. However, rates of DDIs with contraindicated medications are low, suggesting these risks are manageable by infectious disease specialists who have experience with the use of PK enhancers. In this review, we provide an overview of ritonavir's mechanisms of action and describe approaches and resources available to mitigate adverse events and manage concomitant medication in both chronic and short-term settings.

HIV/AIDS and its marker diseases-manifestations

An objective confirmation of the seriousness of the human community’s understanding of the global significance of such a «relatively young» infection as HIV/AIDS is the extensive discussions — the discussion of this seemingly purely medical problem at several meetings of the UN General Assembly, as well as the creation of a specialized UNAIDS program (of the United Nations AIDS Program) which this year published a final report entitled «In danger». It assessed the current situation with this infectious disease as an absolute threat to the entire modern human society. Objective — to conduct an analysis of professional publications of recent years regarding the modern clinical and epidemiological features of the clinical course of HIV-infection/AIDS and to determine organizational measures to ensure at least partial well-being of the public health of the population of Ukraine in wartime conditions and the conduct of active hostilities. It is important to emphasize to primary care physicians not only the significant variety of clinical manifestations of various forms of this acutely contagious viral pathology, but also the real possibility of visually diagnosing it — suspecting it at a daily outpatient polyclinic appointment, based on the clinical manifestations of numerous marker diseases already present on the skin and mucous membranes. Materials and methods. Official documents and scientific publications related to public health policy, approaches to overcoming the HIV/AIDS epidemic, dynamics of morbidity and specific manifestations and clinical course of certain marker dermatological manifestations of this viral pathology in Ukraine were analyzed. Results and discusion. The content of the analyzed professional publications indisputably shows that the problem of HIV/AIDS has gone far beyond the scope of the purely medical field and has acquired the status of national significance. A modern approach to improving the state of public health requires constant coordination of the efforts of different people, who at the same time have a wide range of professional skills in many different disciplines, as well as the ability to collaborate fruitfully with others in joint multiprofessional teams to achieve the common goal of overcoming this viral epidemic. Conclusions. The analysis of scientific publications of recent years on the problem of HIV/AIDS indicates an urgent need to consider this disease in the state public health system as a socially significant infectious disease of the whole organism, in which early visual identification on the skin of clinical manifestations of a number of marker dermatoses allows prompt suspicion, and then and to quickly confirm both the fact of HIV infection and to start a course of ART. This requires an interdisciplinary approach and systematic methodological cooperation of primary care physicians, dermatovenerologists, infectious disease specialists, and pathologists in the aspect of timely (early) diagnosis and complex therapy of this viral infectious pathology.

Neurocysticercosis of the third ventricle: illustrative case.

Neurocysticercosis is a parasitic infection of the central nervous system. Cysts located in the ventricles, intraventricular neurocysticercosis (IVNCC), can cause symptoms of increased intracranial pressure and, if untreated, can be fatal. Neuroendoscopic removal of IVNCC is recommended as the first-line treatment. The authors present the case of a healthy 30-year-old male originally from Mexico who presented with headaches and vomiting. He was found to have a cyst in the third ventricle on imaging, consistent with IVNCC. The authors successfully performed neuroendoscopic surgery with removal of the cyst en bloc. A multidisciplinary team of neurosurgery and infectious disease specialists is recommended for successful management of patients with IVNCC. These patients typically require neuroendoscopic surgical removal for definitive treatment. In this case, the authors show surgery resulted in an effective cure without the need for antiparasitic medication and excellent long-term outcomes.

Hospitalists’ COVID-19 management roles in hospitals without infectious disease specialists

ABSTRACT Background Hospitalists may work in a variety of clinical settings to manage COVID-19 cases. However, the extent of their involvement in COVID-19 care is unknown, particularly in hospitals without infectious disease (ID) specialists. Methods This study aimed to confirm whether hospitalists provided COVID-19 management in various clinical settings when ID specialists were unavailable. We conducted a multicenter cross-sectional study using a web-based questionnaire. The participants were full-time hospitalists working in Japanese academic community-based hospitals. The study period was from 15 January 2021 to 15 February 2021, during Japan’s third wave of the COVID-19 pandemic. The primary outcome was the rate of hospitalists participating in COVID-19 inpatient management in hospitals with or without ID specialists. Results ID specialists were absent in 31% of small hospitals (those with fewer than 249 registered beds), but only 4% of large hospitals (p < 0.001). Hospitalists were more likely to manage both COVID-19 inpatient care and emergency department care in hospitals without than with hospitals with ID specialists (76 versus 56% (p = 0.01) and 90 versus 73% (p = 0.01), respectively). After adjusting for confounders by multivariate analysis, hospitalists who worked in hospitals without ID specialists had higher odds of participating in COVID-19 inpatient care than those who worked in hospitals with such specialists (adjusted odds ratio: 3.0, 95% CI: 1.2–7.4). Conclusion Hospitalists were more likely to provide COVID-19 inpatient care in various clinical settings in hospitals without ID specialists.

The Results of Work of Infectious Disease Specialists and Epidemiologists of the Rospotrebnadzor during the Outbreak of Acute Intestinal Infections in the Republic of the Congo (Brazzaville) in 2023

This paper provides an analysis of the results of joint work of Russian and Congolese infectious disease specialists and epidemiologists to decipher the etiology and causes of the outbreak of intestinal infections in Dolisie (Republic of the Congo) in the summer of 2023. It has been found that the increase in the incidence of intestinal infections was caused mainly by the agents of typhoid fever and dysentery; tropical malaria was a combined pathology. No cases of cholera patient detection were registered. Failure of water supply system, domestic disrepair, and low public awareness about prevention of intestinal infections contributed to the active transmission of pathogens. The combination of epidemic process manifestations testified to the aquatic nature of the outbreak. Also, cases of pathogen transmission through contact household route were recorded, food transmission was not excluded. Patients with severe and complicated forms of typhoid fever and shigellosis accounted for 50 % of those hospitalized. There was delay in seeking medical care. The available regimens of antibacterial therapy were ineffective, since there was no possibility of laboratory confirmation of the diagnosis with determination of sensitivity to drugs. Uncontrolled treatment facilitated the emergence of antibiotic resistance in pathogens, prolonged bacterial release and subsequent spread of infection. Infectious disease specialists and epidemiologists of the Rospotrebnadzor provided consulting and practical assistance to Congolese colleagues, developed and presented recommendations for optimizing anti-epidemic and therapeutic measures, taking into account the results of assessment of the causes for onset and development of the outbreak.

Falciparum malaria case acquired by wound exposed to the blood of infected malaria patient

Malaria is a serious Anopheles mosquito-borne disease. It is not endemic in Egypt but continues to be imported by travelers returning from endemic areas. The transmission of malaria in non-endemic areas is an extremely unusual event, but it is possible under certain conditions.Herein, we report a case of prolonged fever in a patient living in the countryside of Egypt with no reported travel history following accidental blood exposure to a malaria patient. The purpose is to shed light on this rare mode of malaria transmission and also to alert physicians and infectious disease specialists to consider malaria in the differential diagnosis in case of contact history to the blood of a malaria patient.

Recommandations françaises 2023 pour le diagnostic et la prise en charge des bursites septiques prépatellaires et olécraniennes

Septic bursitis (SB) is a common condition accounting for one third of all cases of inflammatory bursitis. It is often related to professional activities. Management is heterogeneous and either ambulatory or hospital-based, with no recommendations available. This article presents recommendations for managing patients with septic bursitis gathered by 18 rheumatologists from the French Society for Rheumatology work group on bone and joint infections, 1 infectious diseases specialist, 2 orthopedic surgeons, 1 general practitioner and 1 emergency physician. This group used a literature review and expert opinions to establish 3 general principles and 11 recommendations for managing olecranon and prepatellar SB. The French Health authority (Haute Autorité de santé [HAS]) methodology was used for these recommendations. Designed for rheumatologists, general practitioners, emergency physicians and orthopedic surgeons, they focus on the use of biological tests and imaging in both outpatient and inpatient management. Antibiotic treatment options (drugs and duration) are proposed for both treatment modalities. Finally, surgical indications, non-drug treatments and prevention are covered by specific recommendations.

Clinical and radiological septic joint analysis of spontaneous sternoclavicular joint infections: achieving the best outcomes-a systems engineering approach.

Spontaneous sternoclavicular joint infection (SSCJI) is a rare and poorly understood disease process. This study aims to identify factors guiding effective management strategies for SSCJI by using data mining. An Institutional Review Board-approved retrospective review of patients from 2 large hospitals (2010-2022) was conducted. SSCJI is defined as a joint infection without direct trauma or radiation, direct instrumentation or contiguous spread. An interdisciplinary team consisting of thoracic surgeons, radiologists, infectious disease specialists, orthopaedic surgeons, hospital information experts and systems engineers selected relevant variables. Small set data mining algorithms, utilizing systems engineering, were employed to assess the impact of variables on patient outcomes. A total of 73 variables were chosen and 54 analysed against 11 different outcomes. Forty-seven patients [mean age 51 (22-82); 77% male] met criteria. Among them, 34 underwent early joint surgical resection (<14 days), 5 patients received delayed surgical intervention (>14 days) and 8 had antibiotic-only management. The antibiotic-only group had comparable outcomes. Indicators of poor outcomes were soft tissue fluid >4.5 cm, previous SSCJI, moderate/significant bony fragments, HgbA1c >13.9% and moderate/significant bony sclerosis. This study suggests that targeted antibiotic-only therapy should be considered initially for SSCJI cases while concurrently managing comorbidities. Patients displaying indicators of poor outcomes or no symptomatic improvement after antibiotic-only therapy should be considered for surgical joint resection.

Diagnostic imaging of the diabetic foot: an EANM evidence-based guidance.

Consensus on the choice of the most accurate imaging strategy in diabetic foot infective and non-infective complications is still lacking. This document provides evidence-based recommendations, aiming at defining which imaging modality should be preferred in different clinical settings. This working group includes 8 nuclear medicine physicians appointed by the European Association of Nuclear Medicine (EANM), 3 radiologists and 3 clinicians (one diabetologist, one podiatrist and one infectious diseases specialist) selected for their expertise in diabetic foot. The latter members formulated some clinical questions that are not completely covered by current guidelines. These questions were converted into statements and addressed through a systematic analysis of available literature by using the PICO (Population/Problem-Intervention/Indicator-Comparator-Outcome) strategy. Each consensus statement was scored for level of evidence and for recommendation grade, according to the Oxford Centre for Evidence-Based Medicine (OCEBM) criteria. Nine clinical questions were formulated by clinicians and used to provide 7 evidence-based recommendations: (1) A patient with a positive probe-to-bone test, positive plain X-rays and elevated ESR should be treated for presumptive osteomyelitis (OM). (2) Advanced imaging with MRI and WBC scintigraphy, or [18F]FDG PET/CT, should be considered when it is needed to better evaluate the location, extent or severity of the infection, in order to plan more tailored treatment. (3) In a patient with suspected OM, positive PTB test but negative plain X-rays, advanced imaging with MRI or WBC scintigraphy + SPECT/CT, or with [18F]FDG PET/CT, is needed to accurately assess the extent of the infection. (4) There are no evidence-based data to definitively prefer one imaging modality over the others for detecting OM or STI in fore- mid- and hind-foot. MRI is generally the first advanced imaging modality to be performed. In case of equivocal results, radiolabelled WBC imaging or [18F]FDG PET/CT should be used to detect OM or STI. (5) MRI is the method of choice for diagnosing or excluding Charcot neuro-osteoarthropathy; [18F]FDG PET/CT can be used as an alternative. (6) If assessing whether a patient with a Charcot foot has a superimposed infection, however, WBC scintigraphy may be more accurate than [18F]FDG PET/CT in differentiating OM from Charcot arthropathy. (7) Whenever possible, microbiological or histological assessment should be performed to confirm the diagnosis. (8) Consider appealing to an additional imaging modality in a patient with persisting clinical suspicion of infection, but negative imaging. These practical recommendations highlight, and should assist clinicians in understanding, the role of imaging in the diagnostic workup of diabetic foot complications.
