RESUMO
BACKGROUND: Monocyte activation is a driver of inflammation in the course of chronic HIV infection. Prostaglandin E2 (PGE2) is known to mediate anti-inflammatory effects, notably the inhibition of tumor necrosis factor- (TNF-) production by monocytes. We aim to investigate the effects of PGE2 on activation of monocytes in chronic HIV infection and the mechanisms through which PGE2 modulates their inflammatory signature. METHODS: We recruited a group of people with HIV (PWH) and matched healthy uninfected persons. We compared plasma levels of PGE2, monocyte activation, and sensitivity of monocytes to the inhibitory actions mediated by PGE2. RESULTS: We found increased plasma levels of PGE2 in PWH, and an activated phenotype in circulating monocytes, compared with uninfected individuals. Monocytes from PWH showed a significant resistance to the inhibitory actions mediated by PGE2; the concentration of PGE2 able to inhibit 50 of the production of TNF- by lipopolysaccharide-stimulated monocytes was 10 times higher in PWH compared with uninfected controls. Furthermore, the expression of phosphodiesterase 4B, a negative regulator of PGE2 activity, was significantly increased in monocytes from PWH. CONCLUSIONS: Resistance to the inhibitory actions mediated by PGE2 could account, at least in part, for the inflammatory profile of circulating monocytes in PWH.

A brain abscess is a focal infection characterized by a collection of pus in the brain parenchyma. It is a life-threatening condition that should be diagnosed and treated as soon as possible. We report here three cases of patients with otogenic brain abscesses of polymicrobial origin that had in common the isolation of Actinomyces europaeus, which has not been previously described in this location. A. europaeus was identified by the conventional methodology, matrix-associated laser deionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing. Antibiotic susceptibility was evaluated by the epsilometric method, and all isolates showed sensitivity to penicillin, vancomycin and linezolid, whereas susceptibility to clindamycin and erythromycin was variable. MALDI-TOF MS identification allowed a quick and reliable species level identification in order to provide a rapid and effective response to avoid treatment delay that could lead to increased morbidity and even mortality.

This study analysed Strongyloides stercoralis genetic variability based on a 404 bp region of the cox1 gene from Latin-American samples in a clinical context including epidemiological, diagnosis and follow-up variables. A prospective, descriptive, observational study was conducted to evaluate clinical and parasitological evolution after ivermectin treatment of 41 patients infected with S. stercoralis. Reactivation of the disease was defined both by clinical symptoms appearance and/or direct larvae detection 30 days after treatment or later. We described 10 haplotypes organized in two clusters. Most frequent variants were also described in the Asian continent in human (HP24 and HP93) and canine (HP24) samples. Clinical presentation (intestinal, severe, cutaneous and asymptomatic), immunological status and eosinophil count were not associated with specific haplotypes or clusters. Nevertheless, presence of cluster 1 haplotypes during diagnosis increased the risk of reactivation with an odds ratio (OR) of 7.51 [confidence interval (CI) 95% 1.3844.29, P = 0.026]. In contrast, reactivation probability was 83 times lower if cluster 2 (I152V mutation) was detected (OR = 0.17, CI 95% 0.020.80, P = 0.02). This is the first analysis of S. stercoralis cox1 diversity in the clinical context. Determination of clusters during the diagnosis could facilitate and improve the design of follow-up strategies to prevent severe reactivations of this chronic disease.

Desulfovibrio spp. are strict anaerobes that are ubiquitous in nature. They can reside in the human or animal gastrointestinal tract and, as they are also environmental bacteria, may be present in soil and water. They can persist asymptomatically in the intestine or behave as opportunistic pathogens associated with primary bacteremia and intraabdominal infections. Several Desulfovibrio spp. infections may be underestimated due to their slow growth rate and because many laboratories do not routinely perform anaerobic cultures. Simple tests such as motility detection on a fresh subculture, Gram stain to confirm cell morphology, presence of H2S in SIM agar and production of a red fluorescence in alkaline pH under UV light would be indicative of Desulfovibrio spp. Here we report the case of Desulfovibrio desulfuricans bacteremia in a woman with clinical picture of abdominal sepsis due to gangrenous appendicitis with multiple organ failure.

Vaccination is one of the most effective strategies for disease prevention. Argentina initiated the transition from child vaccination to family vaccination through the incorporation of an adult schedule. One of the difficulties with this last group is to assess the percentage of use (PU) of the vaccines. With the aim of determining the PU of adult vaccines in Argentina, a vaccination module was included in the National Survey of Risk Factors carried out in 2013 by the National Ministry of Health. The sampling had a stratified multistage design. A total of 32 365 people = 18 year-old were surveyed about the use of four vaccines included in the National Vaccination Calendar: hepatitis B, tetanus, influenza, and pneumococcus. The entire population was surveyed for tetanus and hepatitis B while certain groups at risk were evaluated for influenza and pneumococcus, according to current recommendations. PU varied according to the vaccine analyzed: tetanus 49.8%, hepatitis B 21.7%, influenza 51.6% and pneumococcus 16.2%. The main information sources on adult vaccination were media (television, internet, etc.) followed by health personnel (70.8% and 27.9%, respectively). The survey is a suitable tool to assess the use of vaccines by adults, identify low coverage populations, and to plan and implement strategies to improve coverage.

Vitamin D has immunomodulating properties. The nuclear receptor for vitamin D is expressed in several immune cells, which convert 25-hydroxyvitamin D (25OHD) to the active form 1,25 hydroxyvitamin D [1,25(OH)2 D]. Under conditions of infection, 1,25(OH)2 D promotes production of cathelicidin (an antimicrobial peptide) in monocytes and activated macrophages. In vitro studies have shown the ability of cathelicidin to inhibit replication of human immunodeficiency virus (HIV-1) in T CD4 lymphocytes and macrophages. OBJECTIVE: To evaluate vitamin D levels and their impact on mineral metabolism in HIV infected patients. MATERIALS AND METHODS: Seventy-four clinical records of HIV/AIDS patients seen at the outpatients clinic were reviewed. The following data were collected: age, sex, time since diagnosis of HIV, HIV-1 viral load, CD4 counts (absolute value and percentage), and mineral metabolism determinations: 25OHD, intact parathormone (iPTH); serum calcium (sCa); serum phosphorus (sP) and serum crosslaps (sCTX). Vitamin D levels were stratified as follows: optimal: ≥30ng/ml; insufficient: 21-29ng/ml; moderately deficient: 20≥ -25OHD- >10 ng/ml and severely deficient ≤10 ng/ml. RESULTS: Fifty-five clinical records were included; 82% of patients had 25OHD levels below 30ng/ml (insufficient: 23.6%, moderately deficient: 36.4%; and severely deficient: 21.8%). A significantly higher serum PTH levels in the moderately and severely deficient groups than in the optimal and insufficient groups was observed (p<0.05 and p<0.03 respectively). A weak negative correlation was observed between serum 25OHD and PTH levels (r=-0.268; p<0.004). CONCLUSION: Sub-optimal vitamin D levels are frequently observed in HIV/AIDS patients on antiretroviral therapy (ART). Systematic assessment of mineral metabolism is considered necessary in HIV/AIDS positive patients.
RESUMO
A group of interdisciplinary experts (cardiologists, clinicians, infectologists met with the purpose of analyzing the evidence revealed by the relationship between respiratory diseases caused by influenza, pneumococcal diseases and cardiovascular events, and the role played by immunization strategies applied in cardiovascular prevention. The present statement summarizes the conclusions reached by the expertise of the aforementioned professionals. Systematic revisions imply consistent evidence that influenza and pneumococcal infection lead to acute myocardial infarction and cardiovascular death. Studies published during the last 15 years suggest that vaccination against influenza and S. pneumoniae reduce the risk of acute coronary syndromes. With the current evidence, and considering cost-effectiveness, reducing operating expenses and safety profile of the vaccines, scientific societies, national and international government health agencies strongly recommend incorporating immunization programs in those patients with chronic cardiovascular disease.

Following the COVID-19 pandemic, the Americas faced a significant decline in vaccination coverage as well as increased vaccine hesitancy. The objective of this paper is to summarize the challenges and opportunities outlined by the National Immunization Technical Advisory Groups (NITAGs) in Latin America and the Caribbean (LAC) and prioritize targeted interventions. The exploratory survey included open-ended questions on two primary components: challenges, and opportunities. Free-text comments presented by each NITAG were collated and classified using indicators and sub-indicators of the NITAG Maturity Assessment Tool (NMAT). Opportunities were classified thematically, and priority actions were generated from the responses. All 21 NITAGs in LAC, representing 40 countries, 76 % of which have been active for over a decade, responded to the survey. The most common challenges were establishment and composition (62 %), integration into policymaking (62 %), resources and secretariat (52 %), and stakeholder recognition (48 %). The distribution of responses was seen across the whole sample and did not suggest a more pronounced need in relation to year of establishment. Opportunities included maximizing the Regional NITAG Network of the Americas (RNA) to facilitate collaboration, information sharing, visibility, and communication; existing global, regional, and systemic analyses; the World Health Organization/Pan American Health Organization (WHO/PAHO) templates for standard operating procedures; twinning programs with mature NITAGs; and NITAGs in governance structures. Action plans were outlined to formalize the establishment of NITAGs and broaden their composition; strengthen decision-making and access to data resources; and enhance the credibility of evidence-based recommendations and their uptake by policymakers and the public. NITAG challenges are not unique to LAC. NITAGs have outlined a short-term prioritized action plan which is critical to enhancing NITAG value and importance in countries.

Mucormycosis is an opportunistic infection caused by fungi of the order Mucorales. It is characterized by rapid progression and high morbidity and mortality in the absence of early diagnosis and prompt treatment. It was an infrequent disease, but in recent years, its incidence appears to have increased. The aim of this paper is to report the cases of mucormycosis diagnosed from 1982 to 2010 at the Hospital de Clinicas José de San Martín, University of Buenos Aires. We diagnosed 10 cases of mucormycosis; the first three between 1982 and 2004 and the last 7 between 2005 and 2010. The incidence from 1980 to 2004 was 0.13 patient-years and the frequency 0.1/10 000 discharges (95% CI 0.00- 0.3). In the period 2005 to 2010, the incidence was 0.86 patients per year with 1.1/10 000 discharges (95% CI 0.5-2.4). There was a pulmonary mucormycosis case (in a patient treated with corticosteroids) and nine rhinocerebral cases, two in neutropenic and seven in diabetic patients. The diagnosis was made by observation of cenocytic hyphae in 10/10 patients. Mucorales were recovered in 8/9 cultures (5 Rhizopus spp and 3 Mucor spp.). In one case diagnosis of pulmonary mucormycosis was made post-mortem. Nine patients were treated with amphotericin B deoxycholate (in 3 patients supplemented with liposomal amphotericin B) and surgery. Three patients underwent hyperbaric chamber. Seven patients had favorable outcome. In conclusion, mucormycosis is a rare disease, but its incidence has increased over the past five years. A good evolution of the patients is linked to early diagnosis and treatment.

Vibrio vulnificus is one of the most virulent Vibrio species known. It is a bacterium with universal distribution. The first case registered in Uruguay occurred in 2001 and, since then, several infections have occurred per year. Recently, in this country, V. vulnificus was responsible for a fatal soft tissue infection. Although no cases of human infection with this species have been reported in Argentina, researchers have recently identified V. vulnificus in samples associated with microplankton in the Rio Negro estuary. We present the case of a severe skin and soft tissue infection by V. vulnificus from an open wound in a patient in contact with a marine aquatic environment on the coast of the River Plate, in Uruguay. Isolation of vibrios from wound specimens can cause rapidly progressing tissue damage, particularly V. vulnificus which has a high mortality rate without early and appropriate intervention. In our case, the rapid identification of the microorganism allowed us to support the empirical treatment used, which a good clinical evolution.

El primer caso registrado en Uruguay se produjo en 2001, y desde entonces ocurren varias infecciones por año. Recientemente, en ese país, V. vulnificus fue responsable de una infección de partes blandas de curso letal. Aunque no han sido comunicados casos de infección humana por esta especie en Argentina, se ha identificado recientemente Vibrio vulnificus en muestras asociadas con microplancton en el estuario del Río Negro. Presentamos el caso de una infección grave de piel y partes blandas por V. vulnificus a partir de una herida abierta en un paciente en contacto con medio acuático marino en la costa de Uruguay del Río de la Plata. El aislamiento de vibrios en muestras de heridas puede causar un daño en los tejidos con rápida progresión, en particular V. vulnificus, que tiene una alta mortalidad sin la precoz y apropiada intervención. En nuestro caso, la rápida identificación del microorganismo permitió avalar el tratamiento empírico utilizado, con una buena evolución clínica.

Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus SARS-CoV-2, emerged in Wuhan, China, in December 2019 and rapidly spread around the world. Invasive aspergillosis has been reported as a complication of severe influenza pneumonia among intensive care patients. Similarities between COVID-19 and influenza pneumonia, together with limited published case series, suggest that aspergillosis may be an important complication of COVID-19. This report describes a case of ventilator-associated pneumonia involving Aspergillus flavus in a patient with COVID-19 from Buenos Aires, Argentina.
RESUMO
Cardiovascular diseases are the leading cause of death in most regions of the world, usually followed by infectious diseases. For decades, infections in general, and particularly those involving the respiratory system, have been known to be associated with an increased risk of cardiovascular and cerebrovascular events, and their consequent morbidity and mortality. Although vaccines are an excellent strategy in the prevention of infectious diseases, the proportion of immunized adults in our country is frankly deficient. Multiple barriers contribute to perpetuating this problem, within which the lack of prescription of the same by professionals who care for vulnerable populations occupies a central place. Patients with cardiovascular disease represent a particularly risky subpopulation. The spectrum of pathologies that can trigger respiratory infections is wide: development or worsening of heart failure, arrhythmias, acute coronary syndromes and cerebrovascular diseases, among the main ones. The role of immunoprophylaxis with influenza, pneumococcal and tetanus vaccine in patients with different heart diseases is addressed here, evaluating the evidence supporting its use, and placing special emphasis on practical aspects of its use, such as adverse effects, contraindications and special care situations, such as congenital heart disease in adults, heart transplantation, anticoagulation or egg allergy. Thus, this document aims to assist in decision-making for any doctor involved in the care of patients with cardiovascular disease.
Las enfermedades cardiovasculares ocupan la primera causa de muerte en la mayoría de las regiones del mundo, seguidas habitualmente por las enfermedades infecciosas. Desde hace décadas se conoce que las infecciones en general, y particularmente las que involucran el aparato respiratorio, se vinculan con un incremento en el riesgo de eventos cardiovasculares y cerebrovasculares, y su consecuente morbimortalidad. Si bien las vacunas constituyen una excelente estrategia en la prevención de enfermedades infectocontagiosas, la proporción de adultos inmunizados en nuestro país es francamente deficitaria. Múltiples barreras contribuyen a perpetuar esta problemática, dentro de las cuales la falta de prescripción de las mismas por parte de los profesionales que atienden a poblaciones vulnerables ocupa un lugar central. Los pacientes con enfermedades cardiovasculares representan una subpoblación de particular riesgo. El espectro de enfermedades que pueden originar las infecciones respiratorias es amplio: desarrollo o empeoramiento de insuficiencia cardíaca, arritmias, síndromes coronarios agudos y enfermedades cerebrovasculares, entre los principales. Se aborda aquí el rol de la inmunoprofilaxis con vacuna antigripal, antineumocócica y antitetánica en pacientes con diferentes cardiopatías, valorando la evidencia que respalda su empleo y haciendo especial hincapié en aspectos prácticos de su utilización, como efectos adversos, contraindicaciones y situaciones especiales de atención: cardiopatías congénitas del adulto, trasplante cardíaco, individuos anticoagulados o con alergia al huevo. Así, este documento tiene como objetivo asistir en la toma de decisiones a cualquier médico involucrado en el cuidado de pacientes con enfermedad cardiovascular.

Resumen El absceso cerebral es una infección focal caracterizada por acumulación de pus enel parénquima cerebral; su diagnóstico es de urgencia debido a la alta mortalidad que acarrea.Presentamos tres casos de pacientes con abscesos cerebrales con foco otogénico de origen poli-microbiano, que presentaron en común el aislamiento de Actinomyces europaeus, agente nodescrito hasta el momento en esta localización. A. europaeus fue identificado por la metodo-logía convencional, por espectrometría de masas por desorción/ionización asistida por matriz(MALDI-TOF MS) y por secuenciación del gen ARNr 16S. La sensibilidad antibiótica se evaluó porel método epsilométrico. Todos los aislados presentaron sensibilidad a penicilina, vancomicinay linezolid, mientras que la sensibilidad a clindamicina y eritromicina fue variable. La iden-tificación por MALDI-TOF MS permitió arribar a nivel de especie de forma rápida y confiabley dar una respuesta oportuna y efectiva, evitando el retraso en el tratamiento, lo que sueleincrementar la morbimortalidad del cuadro clínico.
RESUMO
La neumonía adquirida en la comunidad (NAC) sigue siendo una importante causa de morbilidad y mortalidad en la población adulta. Uno de los aspectos importantes en el manejo de esta patología es la toma de decisiones en lo que se refiere al tratamiento antibiótico recomendado, la decisión de un manejo ambulatorio o en internación (tanto en áreas generales como en unidades de cuidados intensivos) y la evaluación del pronóstico del paciente

Introducción: Es frecuente que, luego de un episodio de COVID-19, los pacientes persistan con síntomas, lo cual impacta negativamente en su calidad de vida. El objetivo primario de este estudio es determinar los síntomas prevalentes y su duración luego de un episodio de COVID-19 y la persistencia de estos al mes y a los tres meses del episodio. Los objetivos secundarios son describir el lapso entre el episodio de COVID-19, la reinserción laboral o académica y la reanudación de actividad física. Material y métodos: Estudio descriptivo, observacional, en adultos con antecedente de infección por SARS-CoV-2, realizado a través de una encuesta en línea. Se relacionaron variables demográficas y comorbilidades con síntomas durante la infección, al mes y al tercer mes del episodio.Resultados: Participaron 308 personas. Los síntomas más comunes en la fase aguda fueron dolor muscular y fiebre. Al mes, el 89% presentaba síntomas persistentes, siendo los más frecuentes: fatiga y mialgias. Luego de tres meses, 34,85% presentaba síntomas, siendo los más frecuentes: fatiga y anosmia. Solo el 45,7% de las personas logró la reinserción laboral/académica y el 17% de los individuos logró reiniciar actividad física al alta epidemiológica.Discusión: El porcentaje de personas con síntomas persistentes después de un episodio de COVID-19 es alto. La persistencia de los síntomas disminuye con el tiempo, lo cual es un dato alentador para todos aquellos pacientes que consultan por continuar sintomáticos.
Background: It is frequent that patients complain of persistent symptoms after an episode of COVID-19 infection, that worsened their quality of lifeAim: the aim of this study is to describe the main symptoms during a COVID-19 infection and persistent symptoms a month and three months after the episode. Our secondary objective is to describe the period between the COVID-19 episode and resuming work/ studies and exercise routine. Methods: this is a descriptive, observational study that included adults who underwent an episode of SARS-CoV-2 infection. Participants responded to an online survey. We include demographic and comorbidity data and symptoms during infection, and one and three months after infection. Results: 308 people responded to the survey, frequent symptoms during the episode included myalgia and fever. A month after the episode, 89% complained of persistent symptoms, most frequently myalgia and fatigue. Three months after the episode 38.85% complained of persistent symptoms , most frequently fatigue and anosmia. Only 45.7% could resume work/ studies 10 days after the diagnosis, and 17% could resume exercise routine 10 days after the diagnosis. Conclusions: there is a high percentage of people who persisted with symptoms after a COVID-19 infection. We noticed symptoms improved over time, this finding could be encouraged for patients who persist symptomatic after the episode.

In Argentina, the National Technical Advisory Group on Immunizations is represented by the National Immunization Commission (CoNaIn), an organization created by the Ministry of Health in 2000. Recently, the Argentine government has decided to prioritize vaccination as a state policy, emphasizing this strategy as a sign of social equity so CoNaIn was restructured to increase its capacity to formulate sound and evidence-based recommendations. The commission shall consist of a group of immunization experts, representatives of scientific societies, the immunization program and the Ministry of Health. Its functions include the formulation of recommendations on the introduction of vaccines into the immunization program. The recommendations are based on technical, programmatic and social criteria. This decision-making process transparent with the support and advice of experts and scientific societies and guided by available evidence decisions help strengthen the Ministry of Health immunization policy generating greater confidence and support from the population and health professionals.
