RESUMEN
Evaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR were Klebsiella pneumoniae, and 55.3% of XDR were Acinetobacter baumannii. The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025-15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462-3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189-5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076-2.037). We confirm the urgent need to expand stewardship activities to community settings especially in LMI, with more paid attention to the drugs with a higher potential for resistance. Empowering microbiology laboratories and reports to direct prescribing decisions should be prioritized. Supporting stewardship in ICUs, the mixed medical-surgical ones in particular, is warranted.

Infective endocarditis is a growing problem with many shifts due to ever-increasing comorbid illnesses, invasive procedures, and increase in the elderly. We performed this multinational study to depict definite infective endocarditis. Adult patients with definite endocarditis hospitalized between January 1, 2015, and October 1, 2018, were included from 41 hospitals in 13 countries. We included microbiological features, types and severity of the disease, complications, but excluded therapeutic parameters. A total of 867 patients were included. A total of 631 (72.8%) patients had native valve endocarditis (NVE), 214 (24.7%) patients had prosthetic valve endocarditis (PVE), 21 (2.4%) patients had pacemaker lead endocarditis, and 1 patient had catheter port endocarditis. Eighteen percent of NVE patients were hospital-acquired. PVE patients were classified as early-onset in 24.9%. A total of 385 (44.4%) patients had major embolic events, most frequently to the brain (n = 227, 26.3%). Blood cultures yielded pathogens in 766 (88.4%). In 101 (11.6%) patients, blood cultures were negative. Molecular testing of vegetations disclosed pathogens in 65 cases. Overall, 795 (91.7%) endocarditis patients had any identified pathogen. Leading pathogens (Staphylococcus aureus (n = 267, 33.6%), Streptococcus viridans (n = 149, 18.7%), enterococci (n = 128, 16.1%), coagulase-negative staphylococci (n = 92, 11.6%)) displayed substantial resistance profiles. A total of 132 (15.2%) patients had cardiac abscesses; 693 (79.9%) patients had left-sided endocarditis. Aortic (n = 394, 45.4%) and mitral valves (n = 369, 42.5%) were most frequently involved. Mortality was more common in PVE than NVE (NVE (n = 101, 16%), PVE (n = 49, 22.9%), p = 0.042).

BACKGROUND: The role of antiretroviral therapy (ART) for Hepatitis C viral load (HCV-VL) and liver fibrosis is poorly understood. This study aimed at evaluating the influence of ART on HCV-VL and liver fibrosis in human immunodeficiency virus (HIV)/HCV-coinfected patients. METHODS: We conducted a retrospective cohort study of HIV/HCV-coinfected patients followed at a tertiary university hospital. RESULTS: In total, 143 patients were included. In 61 patients, ART initiation was accompanied by an increase in HCV-VL and a decrease in HIV viral load (HIV-VL), whereas ART suspension led to a decrease in HCV-VL and an increase in HIV-VL. Among the 55 HIV-suppressed patients who switched to a raltegravir (RAL)-containing regimen, median HCV-VL levels decreased significantly, while switching to a rilpivirine-containing regimen did not yield a significant reduction. DISCUSSION: If the -treatment of chronic hepatitis starts before ART, ART initiation should be delayed as much as possible. If ART has been started, it is advisable to wait 1 year before initiating chronic hepatitis treatment. RAL as the third agent in an ART regimen could be beneficial in HIV/HCV-coinfected patients, in comparison to other antiretroviral drugs. CONCLUSION: The start and the suspension of ART significantly interferes with HCV-VL in HIV/HCV-coinfected patients.
RESUMEN
BACKGROUND: Antiretroviral therapy dramatically reduced HIV-related morbidity and mortality, prolonging the lifespan of HIV-infected patients. Greater duration of infection and exposure to antiretroviral therapy makes these patients susceptible to traditional cardio-metabolic risk factors and pathologies. The optimal diagnostic protocol for Diabetes Mellitus in these patients is still controversial. Haemoglobin A1c (HbA1c) has been shown to underestimate glycaemia levels and the oral glucose tolerance test (OGTT) has been shown to reveal cases of glucose metabolism disturbances in patients with normal fasting glucose. Thus, this study aimed to determine the prevalence of prediabetes and diabetes in a population of HIV-infected patients undergoing combined antiretroviral therapy, using three different diagnostic methods (fasting glucose, OGTT and HbA1c), to determine the agreement between the different methods and the characteristics associated with each one. METHODS: This study analyzed 220 HIV-infected patients on antiretroviral therapy. Patient characteristics were collected using a standardized protocol. Disturbances of glucose homeostasis were defined by the ADA 2017 criteria. Patients were characterized according to the presence or absence of clinical lipodystrophy, and distributed into four different categories, according to the presence, or absence of either clinical lipoatrophy, or abdominal prominence. Insulin resistance was assessed by HOMA-IR and QUICKI indexes. Agreement between the diagnostic methods was assessed by Cohen's kappa coefficient. RESULTS: There were no patients diagnosed with diabetes with HbA1c. 5.9% prevalence was obtained when OGTT was used, and 3.2% prevalence when fasting glucose was used. Prediabetes had a prevalence of 14.1% when using HbA1c, 24.1% when using OGTT, and 20% when using fasting glucose. In all three methods, glucose homeostasis disturbances were associated with older age and higher resistance to insulin. Regarding other characteristics, associations varied between the three methods. The agreement between them was fair, or slight. CONCLUSIONS: We observed that HbA1c was the method that diagnosed the least amount of cases and that OGTT was the one that diagnosed the most cases. Accordingly, our results indicate that HbA1c underestimated glycaemia levels in this population and that the use of OGTT might allow an earlier diagnosis of glucose homeostasis disturbances, potentially making it possible to avoid severe complications of DM.

BACKGROUND: Combined antiretroviral therapy (cART) in HIV-infected patients has been associated with lipodystrophy, metabolic abnormalities, and an increased risk of cardiovascular disease. Ultrasound measures of carotid artery intima-media thickness (cIMT) have been used as a valid measure of subclinical atherosclerosis and as a tool to predict the risk of cardiovascular events. Our aim was to evaluate the progression of cIMT in HIV-infected patients subjected to cART, with and without lipodystrophy, over a one-year period. METHODS: We performed a one-year prospective cohort study to compare changes in cIMT, metabolic and inflammation markers in HIV-infected patients undergoing cART. Body composition was assessed by dual-energy X-ray absorptiometry (DXA) and abdominal computed tomography (CT). Levels of blood pressure, lipids and inflammatory markers were evaluated, as well as ultrasound measures of cIMT. Lipodystrophy defined by Fat Mass Ratio (L-FMR) is measured as the ratio of the percentage of trunk fat mass to the percentage of lower limb fat mass by DXA. Categorical variables were compared, using the chi-square or Fisher's exact test. Wilcoxon ranks tests and the McNemar chi-square tests were used to compare results of selected variables, from the first to the second year of evaluation. Means of cIMT, adjusted for age, glucose, triglycerides levels, systolic blood pressure (SBP), and waist to hip ratio were calculated, using generalised linear models for repeated measures. RESULTS: L-FMR was present in 44.3% of patients, and the mean of cIMT increased significantly in this group [0.82 (0.26) vs 0.92 (0.33); p = 0.037], as well as in patients without lipodystrophy [0.73 (0.20) vs 0.84 (0.30); p = 0.012]. In the overall sample, the progression of cIMT was statistically significant after the adjustment for age, glucose, triglycerides, and SBP, but the significance of the progression ceased after the adjustment for waist/hip ratio [0.770 (0.737-0.803) vs 0.874 (0.815-0.933); p = 0.514]. CONCLUSIONS: Carotid IMT progressed significantly in both groups of this HIV-infected cohort, however no association between the progression of cIMT and the presence of lipodystrophy defined by FMR was found. Visceral adipose tissue had an impact on the increment of cIMT, both in patients with, and without lipodystrophy defined by FMR.

BACKGROUND: Artemisinin-based therapy is the current standard treatment for non-severe malaria due to Plasmodium falciparum. The potential for asymptomatic liver toxicity of this therapy and its implication in clinical practice is currently unknown. The aim of this study is to assess the hepatic function in patients treated with a standard three-day artemisinin-based regimen and to compare it with the quinine-doxycycline regimen. METHODS: Retrospective and comparative study of returned adult travellers admitted with non-severe P. falciparum malaria. Fifty-seven patients were included: 19 treated with artemisinin-based therapy and 38 with quinine-doxycycline therapy. RESULTS: During treatment, when compared with quinine-doxycycline group, the artemisinin-lumefantrine group presented a higher proportion of significant liver enzyme abnormalities (42 vs. 5%, p < 0.01) and a higher peak value of aspartate aminotransferase (131 vs. 64 U/L, p < 0.01) and alanine aminotransferase (99 vs. 75 U/L, p = 0.05). None of the patients was symptomatic, there were no treatment interruptions and all patients achieved clinical cure. CONCLUSIONS: Treatment of uncomplicated falciparum malaria with artemisinin-based therapy might cause asymptomatic liver enzyme abnormalities in the first days of treatment. Nevertheless, these liver enzyme abnormalities seem to be harmless, asymptomatic and self-limited.

We present the case of a male patient not vaccinated against hepatitis B virus (HBV) and with reactivity to a surface antibody who, after immunosuppression for a multiple myeloma, had HBV reactivation. Pharmacological HBV suppression was tried, but viremia could not be suppressed. Production-detection core mutations or immunity issues can explain this clinical phenomenon.

Tuberculosis (TB) is a global health threat, especially in HIV patients who may experience immune reconstitution inflammatory syndrome (IRIS) upon Mycobacterium tuberculosis infection. Diagnosing and defining IRIS in non-HIV patients remains challenging. A 63-year-old male with acute leukaemia underwent induction therapy with a regimen containing fludarabine. Febrile neutropenia led to further investigations, revealing non-cavitary pulmonary TB, prompting anti-tuberculosis therapy (ATT) alongside resumed leukaemia treatment with sorafenib. Persistent extra-pulmonary TB, specifically lymph node involvement, were observed and IRIS was suspected, evidenced by enlarged lymphadenopathies, scrofula, and skin lesions that developed during the 13-month course of ATT, with no recurrence after its cessation. This article explores a case of lymph node TB-associated paradoxical IRIS in a non-HIV leukaemia patient, revealing the intricate interplay between tuberculosis and haematological malignancies and emphasizing the lack of standardized diagnostic criteria and treatment consensus. Challenges in lymph node TB diagnosis and management highlight the need for tailored therapeutic approaches. The report explores the potential immunomodulatory effects of fludarabine and sorafenib, questioning their roles in TB-IRIS. This case illuminates TB-IRIS dynamics in non-HIV patients, urging further research and collaborative efforts to enhance understanding and outcomes. As medical complexities persist, personalized therapeutic approaches and advancements in TB-IRIS research are crucial.
RESUMEN
Invasive pneumococcal disease is a serious infection with an elevated case-fatality rate that can be even higher among patients with asplenia. Its impact has been blunted by the widespread use of vaccines; even recently, in 2021, two new pneumococcal conjugate vaccines emerged. The authors present a case of a 58-year-old male, splenectomised with the immunisation schedule complete, who died of invasive pneumococcal disease with a fulminant course. It is highlighted that fever in a patient with impaired splenic function is an emergency, and despite the success of immunisation in reducing pneumococcal carriage and invasive disease, serotypes continue to change. Also, the local epidemiology may help guide situations where the immunisation recommendations are dubious regarding the implementation of the new vaccines.
RESUMEN
Cytomegalovirus (CMV) is a type of double-stranded deoxyribonucleic acid virus belonging to the herpesviridae family. Following a primary infection, the virus becomes latent in various types of white blood cells. Cytomegalovirus infection can remain latent or become active, especially in immunocompromised individuals, such as those undergoing hematopoietic stem cell transplantation (HSCT), where CMV reactivation can occur. In this context, CMV infection is common and associated with high rates of morbidity and mortality. Pneumonia is one of the most serious complications, with mortality rates exceeding 50%. Additionally, even in the absence of organ-specific disease, CMV infection is related to increased mortality unrelated to hematologic neoplasm recurrence. Given the frequency and severity of this infection in HSCT patients, it is crucial to implement effective strategies for monitoring, prevention, and treatment. This guideline was developed to identify patient groups that benefit from a systematic approach to CMV infection and to define the most appropriate strategy for each group. Monitoring CMV viral load in peripheral blood is crucial, especially in patients at moderate to high risk of active infection. Primary prophylaxis with letermovir (an antiviral drug) is recommended to reduce the incidence of active infection, especially in high-risk patients. Secondary prophylaxis with valganciclovir (antiviral drug) is recommended after an episode of active infection, while preemptive and disease treatment is based on monitoring viral load and clinical response. The aim of this guideline is to improve the approach to CMV infection in HSCT patients, ensuring an effective and safe preventive and therapeutic approach.
O vírus citomegálico (CMV) é um tipo de vírus de ácido desoxirribonucleico de dupla cadeia que pertence à família herpesviridae. Após uma infeção primária, o vírus torna-se latente em vários tipos de glóbulos brancos. A infeção por CMV pode permanecer latente ou tornar-se ativa, especialmente em indivíduos imunodeprimidos, como aqueles submetidos a transplantes de células progenitoras hematopoiéticas (TPH), onde a reativação do CMV pode ocorrer. Neste contexto, a infeção por CMV é comum e associada a elevadas taxas de morbilidade e mortalidade. A pneumonite é uma das complicações mais graves, com taxas de mortalidade superiores a 50%. Além disso, mesmo na ausência de doença específica do órgão, a infeção por CMV está relacionada com um aumento da mortalidade não relacionada com a recidiva da neoplasia hematológica. Dada a frequência e gravidade desta infeção em doentes submetidos a TPH, é crucial implementar estratégias eficazes de monitorização, prevenção e tratamento. Este protocolo foi desenvolvido para identificar os grupos de doentes que se beneficiam de uma abordagem sistematizada para a infeção por CMV e definir a estratégia mais adequada para cada grupo. A monitorização da carga viral de CMV no sangue periférico é fundamental, especialmente em doentes com risco moderado a elevado de infeção ativa. A profilaxia primária com letermovir (fármaco antiviral) é recomendada para reduzir a incidência de infeção ativa, especialmente em doentes com alto risco. A profilaxia secundária com valganciclovir (fármaco antiviral) é recomendada após um episódio de infeção ativa, enquanto o tratamento de antecipação e de doença é baseado na monitorização da carga viral e na resposta clínica. Este protocolo visa melhorar a abordagem da infeção por CMV em doentes submetidos a TPH, garantindo uma abordagem preventiva e terapêutica eficaz e segura.
RESUMEN
Background: Blood culture-negative endocarditis (BCNE) is a diagnostic challenge, therefore our objective was to pinpoint high-risk cohorts for BCNE. Methods: The study included adult patients with definite endocarditis. Data were collected via the Infectious Diseases International Research Initiative (ID-IRI). The study analysing one of the largest case series ever reported was conducted across 41 centers in 13 countries. We analysed the database to determine the predictors of BCNE using univariate and logistic regression analyses. Results: Blood cultures were negative in 101 (11.65 %) of 867 patients. We disclosed that as patients age, the likelihood of a negative blood culture significantly decreases (OR 0.975, 95 % CI 0.963-0.987, p < 0.001). Additionally, factors such as rheumatic heart disease (OR 2.036, 95 % CI 0.970-4.276, p = 0.049), aortic stenosis (OR 3.066, 95 % CI 1.564-6.010, p = 0.001), mitral regurgitation (OR 1.693, 95 % CI 1.012-2.833, p = 0.045), and prosthetic valves (OR 2.539, 95 % CI 1.599-4.031, p < 0.001) are associated with higher likelihoods of negative blood cultures. Our model can predict whether a patient falls into the culture-negative or culture-positive groups with a threshold of 0.104 (AUC±SE = 0.707 ± 0.027). The final model demonstrates a sensitivity of 70.3 % and a specificity of 57.0 %. Conclusion: Caution should be exercised when diagnosing endocarditis in patients with concurrent cardiac disorders, particularly in younger cases.
RESUMEN
Tracheobronchial injury (TBI) is a rare life-threatening injury that can result from either penetrating or blunt trauma. Treatment may be surgical or conservative, but the evidence regarding which is the best approach is still very scarce. This case report describes the successful conservative management of a 32-year-old male with a traumatic tracheal laceration. The alarming signs and symptoms, the imaging modalities of choice, the rationale behind the treatment strategy, and the most common complications are detailed here. Through this case, the authors wish to highlight the features that should lead to the suspicion of this potentially fatal traumatic injury, as well as raise awareness on how to adequately manage these patients.
RESUMEN
Septic shock is the most dreaded presentation of an infection, carrying a reserved prognosis. Appropriate antimicrobial therapy is therefore the mainstay of treatment, alongside organ support as needed. Legionnaires' disease is mainly due to Legionella pneumophila serogroup 1 but it can be caused by other serogroups and species not detected by the urinary antigen test. Anti-tumour necrosis factor α therapy may increase the risk of invasive fungal infection, which carry a poor prognosis. We present a challenging case of a septic shock due to Legionella pneumophila and Saprochaete clavata infections, with a review of the two infections presented.
RESUMEN
BACKGROUND: COVID-19 is mainly characterized by respiratory manifestations. Nevertheless, neurologic complications have been described, including delirium, which appears to be frequent, prolonged, and severe. METHODS: We conducted a retrospective analysis of demographic, clinical, and laboratory data of two cohorts: patients with COVID-19 admitted to the infectious disease intensive care unit (ID-ICU) and patients admitted to the ID-ICU with other respiratory infections in 2018-2019. Outcomes were defined as the presence, duration, and severity of delirium. Doses of antipsychotics used to control delirium were converted to equivalents and used as delirium severity. Logistics regression models were used to correlate COVID-19 with the outcomes. RESULTS: Ninety-nine patients with COVID-19 and 40 patients without COVID-19 were included. The mean age of the COVID-19 cohort was 63 years, with a male predominance. Delirium developed in 42%, with a median duration of 3 days and an equivalent dose of olanzapine use of 10 mg/day. In univariate analysis, COVID-19 was not associated with the development or different duration of delirium when compared with patients without COVID-19. There was an association between COVID-19 and severity of delirium in a binary logistic regression model controlled to confounding variables. CONCLUSION: COVID-19 is not associated with a higher prevalence or duration of delirium than in cohorts without COVID-19. However, it is associated with more severe forms of delirium.

BACKGROUND: Common variable immunodeficiency disorders (CVID) are a group of primary immunodeficiencies characterized by impaired immunoglobulin production and dysregulated immune response. Neurological manifestations have been described in a few patients, and little is known about its clinic and therapeutic approach. Thus, this work aimed to review the literature on it and to help differentiate CVID from its mimics, especially sarcoidosis. METHODS: We described a case report and included a literature review of inflammatory neurological involvement in CVID. RESULTS: A 32-year-old female patient with a medical history of recurrent bacterial infections, temporal focal epilepsy and granulomatous lung disease under study, and cervix squamous cell carcinoma, was initially admitted to the emergency department due to intracranial hypertension. After excluding infectious and neoplastic etiologies, the most likely hypothesis was that granulomatous pulmonary, cerebral, and leptomeningeal inflammatory involvement were associated with sarcoidosis. Two years later, a diagnosis of CVID was made, and the patient was secondarily diagnosed with Granulomatous and Lymphocytic Interstitial Lung Disease (GLILD) and related inflammatory brain disease - both complications of CVID. After starting targeted treatment with immunoglobulin replacement and pulse glucocorticoids followed by a chronic taper, the patient became stable. However, three consecutive failures in immunoglobulin intake during the COVID-19 pandemic led to disease recurrence with relapse of neurological manifestations. CONCLUSION: This case illustrates the complex multiple organ manifestations of CVID. When granulomatous conditions arise in these patients, a rare lung disease arising in the context of CVID, the GLILD disease with multisystem involvement, should be taken into consideration. Early treatment with combined steroids and immunotherapy seems to be effective in controlling CVID's neurological manifestations.

Implemented control measures brought about by the coronavirus disease 2019 (COVID-19) pandemic have changed the prevalence of other respiratory viruses, often relegating them to a secondary plan. However, it must not be forgotten that a diverse group of viruses, including other human coronaviruses, rhinoviruses, respiratory syncytial virus, human metapneumoviruses, parainfluenza and influenza, continue to be responsible for a large burden of disease. In fact, they are among the most common causes of acute upper and lower respiratory tract infections globally. Viral respiratory infections can be categorised in several ways, including by clinical syndrome or aetiological agent. We describe their clinical spectrum. Distinctive imaging features, advances in microbiological diagnosis and treatment of severe forms are also discussed. Educational aims: To summarise the knowledge on the spectrum of disease that respiratory viral infections can cause and recognise how often they overlap.To learn the most common causes of respiratory viral infections and acknowledge other less frequent agents that may target certain key populations (e.g. immunocompromised patients).To improve awareness of the recent advances in diagnostic methods, including molecular assays and helpful features in imaging techniques.To identify supportive care strategies pivotal in the management of severe respiratory viral infections.
RESUMEN
Introduction: Hepatitis E virus (HEV) infection causes zoonotic hepatitis in Europe, with a higher risk of complications in immunocompromised hosts. HEV natural history in human immunodeficiency virus (HIV) positive patients is not fully understood, and its prevalence is unknown. Objectives: To study the seroprevalence of HEV and prevalence of chronic HEV in HIV-positive patients from Porto, Portugal. Methods: We randomly selected patients from the cohort of HIV-positive patients followed in our hospital. We performed an enzyme-linked immunosorbent assay to search for immunoglobulin G for HEV. When the absorbance/cut-off was inferior to 3.5, the test was repeated, and a confirmatory test executed in that sample. For reactive tests and for immunosuppressed patients (CD4 count < 200/mm3) with nonreactive test, a polymerase chain reaction (PCR) test was also performed. Results: We included 299 patients. The mean age was 48 and 75.3% were men. Regarding HIV infection, the median follow-up time was 10 years, the acquisition was mainly heterosexual contact, and 94% were on antiretroviral therapy. Seventy-six patients (25.4%) had reactive immunoglobulin G (IgG) hepatitis E serology. Patients with a reactive test were older (statistically significant difference). Otherwise, there was no difference between groups concerning birthplace, rural residence, chronic viral hepatitis coinfection, or cirrhosis. Nadir and actual TCD4+ lymphocyte counts did not differ significantly from patients with HEV reactive and nonreactive serology. Gamma-glutamyl-transferase (GGT) was higher in patients with reactive IgG HEV. All serum HEV PCR tests were negative. Conclusions: Seroprevalence of HEV was 25.4% in HIV-positive patients. Older age and higher GGT correlated to HEV reactive IgG test. No cases of current hepatitis E were found.
RESUMEN
We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases-International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (~5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%-90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs' implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

BACKGROUND: Multiple sclerosis treatment has changed in the last years with the emergence of new disease-modifying therapies (DMTs). Despite a better efficacy profile, these drugs raise concerns about infectious risk, which needs to be mitigated. OBJECTIVE: To analyze the results of a systematic collaborative approach between Neurology and Infectious Diseases (ID) Departments in the management of infectious risk and complications in MS patients treated with DMT. METHODS: Retrospective collection of MS patients' demographic and clinical data from clinical records of MS and ID outpatient clinics (2011-2017). RESULTS: We included 149 patients: most had evidence of previous contact with Herpesviridae, and half of them were not immune to hepatitis A and B viruses (HAV and HBV). Vaccines for HAV, HBV, and Streptococcus pneumoniae were administered in 91%, 78%, and 88% of non-immune patients, respectively. JC virus serology monitoring prevented natalizumab (NTZ) initiation or prompted its switch in 34/122 patients. Forty patients had latent tuberculosis, in which 88% were treated. Infectious events occurred in 33 patients, mostly mild urinary, respiratory, and herpes virus group infections. Only three patients required inpatient care. CONCLUSION: Facing the expansion of the new DMT, we highlight the benefits of an interdisciplinary approach for safer use of the chosen treatment.
RESUMEN
Adults infected with SARS-CoV-2 may develop a multisystem inflammatory syndrome (MIS-A) characterized by elevated inflammatory markers and multisystem organ involvement. We report the case of a patient who presented with fever and vomiting at hospital admission. He tested positive for SARS-CoV-2 infection and blood tests showed elevated inflammatory markers. The patient developed acute cardiac dysfunction and shock in less than 24 hours and the echocardiogram revealed an LVEF of 30%. He was discharged 3 weeks later fully recovered. MIS-A should be considered if a compatible syndrome is observed in patients with evidence of SARS-CoV-2 infection by PCR test or serology. LEARNING POINTS: Multisystem inflammatory syndrome should be considered in young adults presenting with shock and elevated inflammatory markers.Multisystem inflammatory syndrome may be highly responsive to parenteral steroids.
