ABSTRACT

Con la llegada de la pandemia por COVID-19 en el año 2020, múltiples diagnósticos y tratamientos de diversas enfermedades quedaron relegados por el impacto del síndrome respiratorio agudo causado por el nuevo coronavirus (SARS-CoV-2) en los sistemas de salud. Teniendo en cuenta la coexistencia de la pandemia por el virus de inmunodeficiencia humana (VIH) y la provocada por el virus SARS-Cov-2, el objetivo del presente trabajo fue recolectar información de un Hospital de Enfermedades Infecciosas de la Ciudad de Buenos Aires y analizar cómo repercutió la pandemia por SARS-CoV-2 en el diagnóstico de las enfermedades que afectan a la población VIH positiva y, a su vez, comparar el estado clínico al ingreso y egreso de las pacientes en el período pre pandemia y durante la misma. Para esto se analizaron 100 epicrisis correspondientes a la sala 16 de internación de mujeres con complicaciones de la enfermedad VIH/SIDA que fueron asistidas en el período entre Enero del 2020 y Julio del 2021, y 74 epicrisis de pacientes internadas en ese mismo sitio en los siete meses previos. Se tuvieron en cuenta múltiples variables como el motivo de ingreso, conocimiento o no del diagnóstico de VIH, indicación de tratamiento antirretroviral y cumplimiento del mismo, antecedentes patológicos de las pacientes, presencia de enfermedades marcadoras de SIDA e infecciones de transmisión sexual, entre otras. Al comparar los datos entre pre-pandemia y pandemia se evidencia que esta última afectó a la población VIH positiva, en aspectos que van desde el retraso en el diagnóstico de la infección por el retrovirus, el inicio o reinicio de los tratamientos antirretrovirales y diferencias en los múltiples diagnósticos de egreso, incrementándose las consultas por trastornos respiratorios y neurológicos. A todo esto se añadieron las dificultades del personal médico para brindar una buena atención dado por el colapso del sistema sanitario que se hizo presente en dicho contexto. Por otra parte, destacar la importancia de la confección correcta y completa de las historias clínicas para lograr una mejor calidad de atención médica


With the arrival of the COVID-19 pandemic in 2020, many diagnoses and treatments of various diseases were relegated due to the impact of the acute respiratory syndrome caused by the novel coronavirus (SARS-CoV-2) in health systems. Taking into account the coexistence of the human immunodeficiency virus (HIV) pandemic and that caused by the SARS-CoV-2 virus, the objective of this study was to collect information from an Infectious Disease Hospital in the City of Buenos Aires and analyze the impact of the SARS-CoV-2 pandemic on the diagnosis of diseases that affect the HIV-positive population. Also, was compared the clinical status at admission and discharge of patients in the pre-pandemic period and during the same. For this, 100 epicrisis (clinical summaries) corresponding to 16 women who were hospitalized in the period between January 2020 and July 2021 were analyzed, and 74 epicrisis from patients hospitalized during the seven previous months. Multiple variables were considered, such as the reason for admission, whether or not there was knowledge of the HIV diagnosis, the presence of antiretroviral treatment and compliance with it, the patient's clinical history, the presence of marker AIDS diseases and sexually transmitted infections. When comparing the data between both periods, it can be clearly observed that the pandemic generated by SARS-CoV-2 affected the population with HIV, in aspects ranging from the delay in the diagnosis of the retroviral infection, the start or restart of antiretroviral treatments and differences in the multiple discharge diagnoses, especially those involvement the respiratory and the central nervous systems, that added new difficulties to the medical staff due to the saturation of the health system. The importance of the correct and complete preparation of medical records is highlighted in order to achieve better clinical care

ABSTRACT

Las infecciones se han convertido en una de las principales complicaciones de los pacientes con neumonía grave por SARS-CoV-2 que ingresan en UCI. El deficiente estado inmunitario, el desarrollo frecuente de fracaso orgánico con necesidad de tratamientos de soporte invasivos y las estancias prolongadas en áreas estructurales en gran medida saturadas de enfermos son factores de riesgo para el desarrollo de infecciones. El Grupo de Trabajo de Enfermedades Infecciosas y Sepsis GTEIS de la Sociedad Española de Medicina Intensiva y Unidades Coronarias SEMICYUC enfatiza la importancia de las medidas de prevención de infecciones relacionadas con los cuidados sanitarios, y de la detección y tratamiento precoz de las principales infecciones en el paciente con infección por SARS-CoV-2. La coinfección bacteriana, las infecciones respiratorias relacionadas con la ventilación mecánica, bacteriemia relacionada con el catéter, infección del tracto urinario asociado a dispositivo e infecciones oportunistas son desarrolladas. (AU)


Infections have become one of the main complications of patients with severe SARS-CoV-2 pneumonia admitted in ICU. Poor immune status, frequent development of organic failure requiring invasive supportive treatments, and prolonged ICU length of stay in saturated structural areas of patients are risk factors for infection development. The Working Group on Infectious Diseases and Sepsis GTEIS of the Spanish Society of Intensive Medicine and Coronary Units SEMICYUC emphasizes the importance of infection prevention measures related to health care, the detection and early treatment of major infections in the patient with SARS-CoV-2 infections. Bacterial co-infection, respiratory infections related to mechanical ventilation, catheter-related bacteremia, device-associated urinary tract infection and opportunistic infections are review in the document.

ABSTRACT

Vibrio cholerae O1 is the aetiological agent of the severe diarrhoeal disease cholera. Annually, there are an estimated 1-4 million cholera cases worldwide and over 140 000 deaths. The primary mode of disease transmission is through the consumption of water or food contaminated with the bacterium. Although cholera patients can be treated effectively using rehydration therapy, the disease remains a major scourge in areas with limited access to clean water and proper sanitation. Its continued prevalence highlights the failure of socioeconomic policies leading to wealth disparities, fragile and dated public infrastructure, and lack of appropriate health surveillance.

ABSTRACT

Candida albicans are polymorphic fungal species commonly occurs in a symbiotic association with the host's usual microflora. Certain specific changes in its usual microenvironment can lead to diseases ranging from external mucosal to severally lethal systemic infections like invasive candidiasis hospital-acquired fatal infection caused by different species of Candida. The patient acquired with this infection has a high mortality and morbidity rate, ranging from 40% to 60%. This is an ill-posed problem by its very nature. Hence, early diagnosis and management is a crucial part. Antifungal drug resistance against the first and second generation of antifungal drugs has made it difficult to treat such fatal diseases. After a few dormant years, recently, there has been a rapid turnover of identifying novel drugs with low toxicity to limit the problem of drug resistance. After an initial overview of related work, we examine specific prior work on how a change in oxidative stress can facilitate apoptosis in C. albicans. Subsequently, it was investigated that Candida spp. suppresses the production of ROS mediated host defense system. Here, we have reviewed possibly all the small molecule inhibitors, natural products, antimicrobial peptide, and some naturally derived semi-synthetic compounds which are known to influence oxidative stress, to generate a proper apoptotic response in C. albicans and thus might be a novel therapeutic approach to augment the current treatment options.

ABSTRACT

INTRODUCTION: Cronobacter sakazakii is an opportunistic Gram-negative, rod-shaped bacterium which may be a causative agent of meningitis in premature infants and enterocolitis and bacteremia in neonates and adults. While there have been multiple cases of C. sakazakii infections, there have been no acute cholangitis cases reported in humans. CASE PRESENTATION: An 81-year-old male with a past medical history of basal cell carcinoma, alcoholic liver cirrhosis, transjugular intrahepatic portosystemic shunt procedure, complicated by staphylococcus bacteremia, pituitary tumor, glaucoma, and hypothyroidism presented to the emergency room with the complaint of diffuse and generalized 10/10 abdominal pain of 1 day's duration. There was a concern for pancreatitis, acute cholangitis, and possible cholecystitis, and the patient underwent a percutaneous cholecystostomy tube placement. Blood cultures from admission and biliary fluid cultures both grew C. sakazakii. The patient was treated with a carbapenem and clinically improved. CONCLUSIONS: The case study described a patient with multiple medical comorbidities that presented with C. sakazakii bacteremia and cholangitis. While this bacterium has been implicated in other infections, we believe this is the first time the bacteria is being documented to have caused acute cholangitis.

ABSTRACT

BACKGROUND: Many studies have shown that invasive pulmonary aspergillosis, cryptococcosis, and mucormycosis can mimic radiographic and clinical features of primary lung cancer. However, more research surveying the incidence and outcomes of these fungal infections among patients with a history of lung cancer is needed. The aim of this study was to describe the occurrence and clinical outcomes of opportunistic invasive fungal infections that can mimic tumors in non-small-cell lung cancer patients. PATIENTS AND METHODS: Patients seen at Stanford University Medical Center from January 1, 2007, to May 1, 2020, with pulmonary aspergillosis, cryptococcosis, or mucormycosis after non-small-cell lung cancer (NSCLC) diagnosis were reviewed. The European Organization for Research and Treatment of Cancer National Institute of Allergy and Infectious Diseases Mycoses Study Group criteria was used to classify patients with evidence of proven or probable invasive fungal infection within our cohort. RESULTS: A total of 12 patients with proven or probable invasive mold infection (including 8 cases of aspergillosis) and 1 patient with proven cryptococcosis were identified, without any cases of mucormycosis. Of this cohort, 6 patients (46%) showed radiographic findings that were found to be most consistent with lung cancer by radiologists. Eight cases (62%) were suspected of cancer recurrence or progression by the treatment team on the basis of additional considerations of medical history and clinical symptoms. Most patients had active NSCLC or had a history of recurrence without active NSCLC at the time of fungal discovery (11 patients; 85%). Most patients died without full recovery (7 patients; 54%). CONCLUSIONS: Invasive pulmonary aspergillosis and cryptococcosis can often be mistaken as cancer recurrence or progression in patients with a history of NSCLC because of mimicking radiographic and clinical characteristics.

ABSTRACT

ABSTRACT: A 56-year-old woman, with history of psoriasis well controlled on ustekinumab, underwent 18F-FDG PET/CT to explore first onset of histologically proven skin panniculitis of unknown origin. PET/CT showed high uptake in panniculitis lesions in limbs and in a lung opacity suggestive of pneumonia. Based on PET/CT findings, a bronchoalveolar lavage revealed pulmonary coinfection by Pneumocystis jirovecii and Cryptococcus neoformans. Thus, hematogenous dissemination of infection was suspected as etiology of panniculitis. She was treated with fluconazole and trimethoprim-sulfamethoxazole, leading to total resolution of skin lesions. Posttherapeutic PET/CT showed complete metabolic response of skin and pulmonary lesions.

ABSTRACT

BACKGROUND/OBJECTIVES: Cutaneous mucormycosis is an emerging opportunistic mycosis caused by Mucorales. It can be divided into primary caused by trauma and secondary by extension of rhino-cerebral and disseminated cases. The objective is to present a retrospective study of cases of mucormycosis with cutaneous involvement. METHODS: A retrospective and descriptive study was carried out. Mucormycosis patients were included and divided into two groups: a) Primary Cutaneous and b) Secondary Cutaneous. Mycological tests were performed; the agents were identified by morphology and molecular studies (PCR and sequencing); some cases underwent histopathology. Clinical data and response to treatment were collected. RESULTS: 115 cases were included, 18 of primary, and 97 of secondary cutaneous mucormycosis. Primary cutaneous mucormycosis was most associated with adhesive bands (44.4%) and trauma from traffic accidents (33.3%). The principal clinical form was extensive and deep necrotic ulcers. Secondary cutaneous mucormycosis cases were rhino-cerebral with uncontrolled diabetes (81.4%) The most frequent clinical presentation was necrosis of the eyelid and the nose (65.9%). In both groups, the principal agent was Rhizopus arrhizus, 38.8% and 74.2% respectively. The most effective treatment was the combination of amphotericin B with surgical debridement. The clinical and mycological cure was achieved in 31.0% of primary cases, and 44.4% for secondary cases. CONCLUSION: Primary cutaneous mucormycosis is caused by implantation of the Mucorales due to trauma or rupture of the cutaneous barrier-breach, and secondary cutaneous mucormycosis develops as part of the rhino-cerebral process. The response to treatment depends on the extension and depth, as well as the predisposing factors.

ABSTRACT

OBJETIVOS: Analizar la eficacia diagnóstica del lavado broncoalveolar y su impacto en el manejo terapéutico en pacientes pediátricos. MATERIAL Y MÉTODOS: Estudio retrospectivo incluyendo a los pacientes a los que se les realizó un lavado broncoalveolar por parte del Servicio de Cirugía Pediátrica entre 2009 y 2019. Se ha dividido la muestra en dos grupos: pacientes hemato-oncológicos y no hemato-oncológicos. Se han recogido variables demográficas, el resultado del lavado broncoalveolar y la actitud terapéutica posterior. RESULTADOS: Se realizaron 45 lavados broncoalveolares en 38 pacientes. El grupo hemato-oncológico constaba de 25 lavados broncoalveolares. Los pacientes tenían una edad media de 9,99 ± 2,34 años. El 80% de los pacientes tenían tratamiento antiinfeccioso previo al lavado broncoalveolar. El cultivo del lavado broncoalveolar fue positivo en el 52% de los casos. El resultado del lavado broncoalveolar influyó en un cambio de manejo terapéutico en un 24% (6/25). Se produjeron 3 complicaciones posoperatorias, todas leves. En el grupo no hemato-oncológico (n = 20) la edad media era de 6,70 ± 5,17 años. El lavado broncoalveolar fue positivo en el 25% y supuso un cambio de manejo en un 5% de los pacientes. Este grupo tuvo una tasa de complicación del 30%, dos pacientes requirieron ventilación mecánica. CONCLUSIONES: Según nuestros resultados, el lavado broncoalveolar en los pacientes hemato-oncológicos ayuda al diagnóstico microbiológico en procesos respiratorios infecciosos y es relativamente bien tolerado. En los no hemato-oncológicos, tiene una baja rentabilidad diagnóstico-terapéutica, con una tasa de complicaciones no desdeñable. Sería necesario individualizar el balance beneficio-riesgo en cada paciente


OBJECTIVE: To analyze bronchoalveolar lavage diagnostic effectiveness and impact on therapeutic management in pediatric patients. MATERIALS AND METHODS: Retrospective study of patients undergoing bronchoalveolar lavage at the pediatric surgery department from 2009 to 2019. The sample was divided into two groups: hemato-oncological patients and non-hemato-oncological patients. Demographic variables, bronchoalveolar lavage result, and subsequent therapeutic attitude were collected. RESULTS: 45 bronchoalveolar lavages were carried out in 38 patients. The hemato-oncological group consisted of 25 bronchoalveolar lavages. Patient mean age was 9.99 ± 2.34 years. 80% of patients had received anti-infective treatment prior to bronchoalveolar lavage. Bronchoalveolar lavage culture was positive in 52% of cases. Bronchoalveolar lavage results translated into therapeutic management change in 24% of cases (6/25). 3 postoperative complications were recorded, all mild. In the non-hemato-oncological group (n = 20), mean age was 6.70 ± 5.17 years. Bronchoalveolar lavage was positive in 25% of cases, and translated into management change in 5% of patients. Complication rate in this group was 30%. 2 patients required mechanical ventilation. CONCLUSIONS: According to our results, bronchoalveolar lavage in hemato-oncological patients helps achieve microbiological diagnosis in infectious respiratory conditions and is relatively well-tolerated. In non-hemato-oncological patients, diagnostic and therapeutic usefulness is low, and complication rate is not negligible. The risk-benefit balance should be individually considered in each patient

ABSTRACT

AIMS: Heart transplantation may represent a particular risk factor for severe coronavirus infectious disease 2019 (COVID-19) due to chronic immunosuppression and frequent comorbidities. We conducted a nation-wide survey of all heart transplant centers in Germany presenting the clinical characteristics of heart transplant recipients with COVID-19 during the first months of the pandemic in Germany. METHODS AND RESULTS: A multicenter survey of all heart transplant centers in Germany evaluating the current status of COVID-19 among adult heart transplant recipients was performed. A total of 21 heart transplant patients with COVID-19 was reported to the transplant centers during the first months of the pandemic in Germany. Mean patient age was 58.6 ± 12.3 years and 81.0% were male. Comorbidities included arterial hypertension (71.4%), dyslipidemia (71.4%), diabetes mellitus (33.3%), chronic kidney failure requiring dialysis (28.6%) and chronic-obstructive lung disease/asthma (19.0%). Most patients received an immunosuppressive drug regimen consisting of a calcineurin inhibitor (71.4%), mycophenolate mofetil (85.7%) and steroids (71.4%). Eight of 21 patients (38.1%) displayed a severe course needing invasive mechanical ventilation. Those patients showed a high mortality (87.5%) which was associated with right ventricular dysfunction (62.5% vs. 7.7%; p = 0.014), arrhythmias (50.0% vs. none; p = 0.012), and thromboembolic events (50.0% vs. none; p = 0.012). Elevated high-sensitivity cardiac troponin T- and N-terminal prohormone of brain natriuretic peptide were significantly associated with the severe form of COVID-19 (p = 0.017 and p < 0.001, respectively). CONCLUSION: Severe course of COVID-19 was frequent in heart transplanted patients. High mortality was associated with right ventricular dysfunction, arrhythmias, thromboembolic events, and markedly elevated cardiac biomarkers.

ABSTRACT

PURPOSE OF REVIEW: Tremendous advances have been made in the treatment armamentarium for acute lymphoblastic leukemia in recent years, which have substantially improved outcomes for these patients. At the same time, unique toxicities have emerged, and without early intervention, are life-threatening. This article will review the novel therapies in acute leukemias and highlight the clinically relevant supportive care advances. RECENT FINDINGS: The American Society for Transplantation and Cellular Therapy (ASTCT) has put forth the most recent recommendations in managing the cytokine release syndrome and neurotoxicity after chimeric antigen receptor T cells (CAR-T) and blinatumomab. The hepatic injury incurred by inotuzumab, and the vascular toxicity of tyrosine kinase inhibitors, other relatively novel agents, require subspecialist intervention and multidisciplinary care. Asparaginase, a long-established and key element of pediatric regimens, has made a comeback in the young adult leukemia population. Updated guidelines have been outlined for management of asparaginase thrombotic complications. Lastly, although there have been few changes in the applications of growth factor, antimicrobial prophylaxis, and management of neuropathy, these encompass exceedingly important aspects of care. While the rapidly changing treatment paradigms for acute lymphoblastic leukemia have transformed leukemia-specific outcomes, treatment emergent toxicities have forced much necessary attention to better definitions of these toxicities and on improving supportive care guidelines in acute lymphoblastic leukemia.

ABSTRACT

Antimicrobial-resistant and novel pathogens continue to emerge, outpacing efforts to contain and treat them. Therefore, there is a crucial need for safe and effective therapies. Ultraviolet-A (UVA) phototherapy is FDA-approved for several dermatological diseases but not for internal applications. We investigated UVA effects on human cells in vitro, mouse colonic tissue in vivo, and UVA efficacy against bacteria, yeast, coxsackievirus group B and coronavirus-229E. Several pathogens and virally transfected human cells were exposed to a series of specific UVA exposure regimens. HeLa, alveolar and primary human tracheal epithelial cell viability was assessed after UVA exposure, and 8-Oxo-2'-deoxyguanosine was measured as an oxidative DNA damage marker. Furthermore, wild-type mice were exposed to intracolonic UVA as an in vivo model to assess safety of internal UVA exposure. Controlled UVA exposure yielded significant reductions in Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Enterococcus faecalis, Clostridioides difficile, Streptococcus pyogenes, Staphylococcus epidermidis, Proteus mirabilis and Candida albicans. UVA-treated coxsackievirus-transfected HeLa cells exhibited significantly increased cell survival compared to controls. UVA-treated coronavirus-229E-transfected tracheal cells exhibited significant coronavirus spike protein reduction, increased mitochondrial antiviral-signaling protein and decreased coronavirus-229E-induced cell death. Specific controlled UVA exposure had no significant effect on growth or 8-Oxo-2'-deoxyguanosine levels in three types of human cells. Single or repeated in vivo intraluminal UVA exposure produced no discernible endoscopic, histologic or dysplastic changes in mice. These findings suggest that, under specific conditions, UVA reduces various pathogens including coronavirus-229E, and may provide a safe and effective treatment for infectious diseases of internal viscera. Clinical studies are warranted to further elucidate the safety and efficacy of UVA in humans.

ABSTRACT

INTRODUCTION: Common major pathogens like Pseudomonas aeruginosa are identified in the airways of patients with cystic fibrosis (CF) and non-CF bronchiectasis. However, other opportunistic bacterial pathogens like Achromobacter xylosoxidans complex, Stenotrophomonas maltophilia and non-tuberculous mycobacteria are currently emerging in CF and are also reported in non-CF bronchiectasis. BACKGROUND: The emergence of opportunistic bacterial pathogens has been recognized in CF through annual national reports of sputum microbiology data. Despite common factors driving the emergence of bacteria identified in CF and non-CF bronchiectasis patients, bronchiectasis registries have been created more recently and no longitudinal analysis of recorded microbiological data is currently available in the literature, thereby preventing the recognition of emerging bacteria in patients with non-CF bronchiectasis. OUTLOOK: A longitudinal follow-up of microbiological data is still needed in non-CF bronchiectasis to identify emerging opportunistic bacterial pathogens. Homogeneity in practice of sputum microbiological examination is also required to allow comparative analysis of data in CF and non-CF bronchiectasis. CONCLUSION: Bacterial pathogens recognized as emerging in CF have to be more carefully monitored in non-CF bronchiectasis in view of their association with deterioration of the lung disease.

ABSTRACT

The BK polyomavirus was isolated in 1971; it has been a significant risk factor for both graft dysfunction and failure in renal transplant recipients. So far, no specific treatment option has been available for effective treatment or prophylaxis for BK virus infections. Although the use of heavy immunosuppression has been the main risk factor for BK virus infection, other risk factors are equally important, including elderly recipients, prior rejection episodes, male sex, human leukocyte antigen mismatching, prolonged cold ischemia time, pretransplant BK virus serostatus, and ureteral stenting. Regular follow-up for BK virus infections according to each institution's policy has been, so far, effective in detecting patients with BK virus viremia and consequently preventing allograft loss. The mainstay of management continues to be reduction of immunosuppression. However, newer options are providing new insights, such as cellular immunotherapy.

ABSTRACT

BACKGROUND: Previous studies on coronavirus disease 2019 (COVID-19) have focused on populations with normal immunity, but lack data on immunocompromised populations. OBJECTIVE: To evaluate the clinical features and outcomes of COVID-19 pneumonia in kidney transplant recipients. DESIGN, SETTING, AND PARTICIPANTS: A total of 10 renal transplant recipients with laboratory-confirmed COVID-19 pneumonia were enrolled in this retrospective study. In addition, 10 of their family members diagnosed with COVID-19 pneumonia were included in the control group. INTERVENTION: Immunosuppressant reduction and low-dose methylprednisolone therapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The clinical outcomes (the severity of pneumonia, recovery rate, time of virus shedding, and length of illness) were compared with the control group by statistical analysis. RESULTS AND LIMITATIONS: The clinical symptomatic, laboratory, and radiological characteristics of COVID-19 pneumonia in the renal transplant recipients were similar to those of severe COVID-19 pneumonia in the general population. The severity of COVID-19 pneumonia was greater in the transplant recipients than in the control group (five severe/three critical cases vs one severe case). Five patients developed transient renal allograft damage. After a longer time of virus shedding (28.4 ± 9.3 vs 12.2 ± 4.6 d in the control group) and a longer course of illness (35.3 ± 8.3 vs 18.8 ± 10.5 d in the control group), nine of the 10 transplant patients recovered successfully after treatment. One patient developed acute renal graft failure and died of progressive respiratory failure. CONCLUSIONS: Kidney transplant recipients had more severe COVID-19 pneumonia than the general population, but most of them recovered after a prolonged clinical course and virus shedding. Findings from this small group of cases may have important implications for the treatment of COVID-19 pneumonia in immunosuppressed populations. PATIENT SUMMARY: Immunosuppressed transplant recipients with coronavirus disease 2019 infection had more severe pneumonia, but most of them still achieved a good prognosis after appropriate treatment.
