RESUMEN

BACKGROUND: Post-streptococcal glomerulonephritis (PSGN) is a consequence of the infection by group A beta-hemolytic streptococcus. During this infection, various immunological processes generated by streptococcal antigens are triggered, such as the induction of antibodies and immune complexes. This activation of the immune system involves both innate and acquired immunity. The immunological events that occur at the renal level lead to kidney damage with chronic renal failure as well as resolution of the pathological process (in most cases). Angiotensin II (Ang II) is a molecule with vasopressor and pro-inflammatory capacities, being an important factor in various inflammatory processes. During PSGN some events are defined that make Ang II conceivable as a molecule involved in the inflammatory processes during the disease. CONCLUSION: This review is focused on defining which reported events would be related to the presence of this hormone in PSGN.

RESUMEN

INTRODUCTION: Since 1980, there have been known cases of childhood neuropsychiatric syndromes in the world and its concept has evolved with changes in the definitions in 1995 (PITANDs - paediatric infection-triggered autoimmune neuropsychiatric disorders), 1998 (PANDAS - paediatric autoimmune neuropsychiatric syndrome associated with streptococci infection), 2010 (PANS - paediatric acute-onset neuropsychiatric syndrome) and 2012 (CANS - childhood acute neuropsychiatric syndrome). Despite being known for more than 20 years, it is still an illness that often goes unnoticed by many health professionals. OBJECTIVE: To sensitise the medical community about the identification of the disease and reduce the morbidity associated with a late diagnosis. CLINICAL CASE: A 6-year-old schoolgirl brought to the emergency department due to her refusal to eat. In the hospital treatment, a clinical history was identified with PANS-PANDAS diagnostic criteria. She exhibited a relapsing-remitting clinical course, as described in the literature, with poor response to first-line treatments. CONCLUSIONS: In all school-age child presenting with obsessive compulsive disorder or eating disorders, with other symptoms or not, a possible link to PANS-CANS should be evaluated and ruled out.

RESUMEN

BACKGROUND: Acute post-streptococcal glomerulonephritis (APSGN) is an immune- complex (ICs) mediated glomerular disease triggered by group A ß-hemolytic streptococcus (GAS) or Streptococcus pyogenes infections. APSGN represents a major cause of acquired kidney injury in children. METHODS: This non-systematic review summarizes recent evidence on APSGN. We discuss the epidemiology, pathogenesis, clinical and laboratory findings, histopathology, treatment and prognosis of the disease. RESULTS: The median APSGN incidence in children in developing countries is estimated at 24.3/100,000 per year, compared with 6.2/100,000 per year in developed countries. Nephritis-associated plasmin receptor, identified as glyceraldehyde-3-phosphate dehydrogenase, and the cationic cysteine proteinase streptococcal pyrogenic exotoxin B are thought to be two leading streptococcal antigens involved in the pathogenesis of APSGN, which activate the complement system, mainly via the alternative but also the lectin pathway. This process is critical for the generation of inflammation by the ICs deposited in the glomerulus. The classic phenotype is an acute diffuse proliferative glomerulonephritis leading to features of the nephritic syndrome, including hematuria, oliguria, hypertension and edema. The histopathology shows that the glomeruli are diffusely affected, mostly presenting enlarged glomerular tuffs due to hypercellularity. Proliferative endothelial and mesangial cells and inflammation have also been observed. APSGN frequently has spontaneous recovery. There is no specific therapy, but its morbidity and mortality are drastically reduced by the prevention and/or treatment of complications. CONCLUSION: Despite recent advances, the pathogenesis of APSGN is not fully understood. There is no specific treatment for APSGN. The prognosis is generally good. However, some cases may evolve into chronic kidney disease.

RESUMEN

Introducción: el estreptococo del grupo B (EGB) es una causa frecuente de sepsis neonatal. La enfermedad precoz disminuyó su incidencia por la profilaxis antibiótica, a diferencia de la sepsis tardía, que aumentó su incidencia en los últimos años. Objetivo: conocer la incidencia de la sepsis tardía en el período 2016-2017 en el Centro Hospitalario Pereira Rossell (CHPR). El secundario, describir las características epidemiológicas y clínicas de sepsis tardía por EGB en niños ingresados a la Unidad de Cuidados Intensivos de Niños (UCIN) del CHPR en el período 2007-2017. Resultados: la incidencia calculada de sepsis tardía por EGB fue de 0,53 casos/1000 recién nacidos (RN) vivos. Entre los años 2007 y 2017 ingresaron cinco niños por sepsis tardía por EGB a la UCIN del CHPR. La presentación clínica más frecuentes fue fiebre sin foco y meningitis. Se obtuvieron tres aislamientos en sangre de EBG y tres en líquido cefalorraquídeo (dos en cultivo y otro por detección de ADN). Ninguno falleció. Los casos con meningitis presentaron alteraciones en la tomografía de cráneo. Un niño fue pretérmino. Conclusiones: la sepsis tardía se vincula a importante morbimortalidad en pediatría. No se ha establecido cuáles son los principales factores de riesgo asociados a una enfermedad grave ni las políticas para disminuir su incidencia.


Background: group B streptococcus (GBS) is a common cause of neonatal sepsis. Early disease decreased its incidence due to antibiotic prophylaxis. Late sepsis increased its incidence in recent years. Objectives: to know the incidence of late onset EGB sepsis in the period 2016-2017 at the Pereira Rossell Hospital Center (CHPR), and secondly, to describe the epidemiological characteristics and the clinical presentation of late onset sepsis due to GBS in children admitted to the Children's Intensive Care Unit (UCIN) of the CHPR in the period 2007-2017. Results: the calculated incidence of late sepsis due to GBS was 0.53 cases/1000 live newborns. Between 2007-2017, 5 children were admitted due to GBS late sepsis at the UCIN. The most frequent clinical presentation was fever without focus and meningitis. 3 isolates were obtained in EBG blood cultures and 3 in cerebrospinal fluid (2 in culture and another by DNA detection). None of them died. Cases with meningitis showed abnormalities in the brain tomography. 1 of the 5 was preterm. Conclusions: late sepsis is associated with significant morbidity and mortality in pediatric patients. The main risk factors associated with serious disease and the policies needed to reduce its incidence have not been established.

RESUMEN

Streptococcus suis (S. suis) is a zoonotic pathogen that primarily inhabits the upper respiratory tract of pigs. Therefore, pigs that carry these pathogens are the major source of infection. Most patients are infected through contact with live pigs or unprocessed pork products and eating uncooked pork. S. Suis mainly causes sepsis and meningitis. The disease has an insidious onset and rapid progress. The patient becomes critically ill and the mortality is high. In this case report, we described a rare case of S. suis isolated from a middle-aged woman in Jinhua City, Zhejiang Province, China, who did not have any contact with live pigs and had not eaten uncooked pork. S. Suis was isolated from both the patient's blood and cerebrospinal fluid samples.

RESUMEN

Acute poststreptococcal GN (APSGN) is the prototype of immune complex GN and is associated with manifestations of autoimmune reactivity that have been neglected as epiphenomena. Recently, studies have demonstrated transient antifactor B autoantibodies that activate the alternative complement pathway, bringing self-immunity to a central position in the pathogenesis of APSGN. Therefore, examining other manifestations of autoimmunity that have been reported in association with poststreptococcal GN is of interest. This article reviews the renal and extrarenal manifestations of autoimmune reactivity in APSGN and considers their potential relevance in modifying the usually benign clinical course of the disease. It also discusses related aspects of the nephritogenic antigens, complement activation, and genetic elements associated with immune reactivity and their potential relevance to the familial incidence of the disease.

RESUMEN

Streptococcus equi subspecies zooepidemicus is a Gram-positive, P-hemolytic coccus considered part of the commensal flora in horses and an opportunistic pathogen in other animals. Infection in humans is rare, but it usually manifests as serious symptoms, it has been associated with contact with animals, especially horses, and the consumption of unpasteurized dairy products. In this report we describe a case of bacteremia of the mother-child binomial by this agent, associated with the consumption of artisan cheeses. Although penicillin is the treatment of choice, the newborn was successfully treated with ampicillin and the mother with ceftriaxone, none of them presented complications associated with bacteremia. To our knowledge, this is the first report of connatal infection by this agent.

RESUMEN

Increasing evidence supports a central role of the immune system in acute post streptococcal glomerulonephritis (APSGN), but the current view of how streptococcal biology affects immunity, and vice versa, remains to be clarified. Renal glomerular immune complex deposition is critical in the initiation of APSGN; however, mechanisms previous to immune complex formation could modulate the initiation and the progression of the disease. Initial and late renal events involved in the nephritis can also be related to host factors and streptococcal factors. In this review we describe the mechanisms reported for the APSGN pathogenesis, the interactions of streptococcal products with renal cells and leukocytes, the possible effects of different nephritogenic antigens in the renal environment and the possibility that APSGN is not just due to a single streptococcal antigen and its antibody; instead, kidney damage may be the result of different factors acting at the same time related to both streptococcus and host factors. Addressing these points should help us to better understand APSGN physiopathology.

RESUMEN

Acute mastoiditis is an infection that affects the mastoid air-cell system, usually due to the progression of an acute otitis media. The bacteria most frequently isolated in acute mastoiditis are Streptococcus pneumoniae, Streptococcus pyogenes and Staphylococcus aureus. The mastoid infection can extend affecting contiguous structures and producing intra or extracranial complications. The most frequent ones are intracranial complications, including meningitis, temporal lobe or cerebellar abscess, epidural or subdural abscess and venous sinus thrombosis. We present the case of a 4-year-old girl who developed two intracranial complications (intracranial epidural abscess and transverse and sigmoid sinus thrombosis) initiated in an acute mastoiditis produced by Streptococcus pyogenes.


La mastoiditis aguda es una infección de las celdillas mastoideas, generalmente, secundaria a la progresión de una otitis media aguda. Las bacterias aisladas con más frecuencia en las mastoiditis son Streptococcus pneumoniae, Streptococcus pyogenes y Staphylococcus aureus. La infección mastoidea puede extenderse por contigüidad, afectar a estructuras vecinas y dar lugar a complicaciones intra- o extracraneales. Las más frecuentes son las intracraneales, entre las que se incluyen la meningitis, el absceso cerebeloso o del lóbulo temporal, el absceso epi- o subdural y la trombosis de senos venosos. Se presenta el caso de una niña de 4 años que desarrolló dos complicaciones intracraneales (absceso epidural y trombosis de senos venosos transverso y sigmoideo) a partir de una mastoiditis aguda producida por Streptococus pyogenes.

RESUMEN

OBJECTIVE: To highlight the pathogenicity of Streptococcus anginosus, which is rare in pediatric patients, but can cause severe infections that are known to have a better outcome when treated early with interventional procedures and prolonged antibiotic therapy. CASE: description: The patient is a 6-year-old boy with global developmental delay, examined in the emergency room due to fever and respiratory distress. The physical examination and diagnostic workout revealed complicated pneumonia with empyema of the left hemithorax; he started antibiotic therapy and underwent thoracic drainage. Pleural fluid cultures grew Streptococcus anginosus. On day 11, the child had a clinical deterioration with recurrence of fever, hypoxia, and respiratory distress. At this point, considering the causative agent, he was submitted to video-assisted thoracoscopic decortication, with good progress thereafter. COMMENTS: Streptococcus anginosus is a commensal bacterium of the human oral cavity capable of causing severe systemic infections. Although reports of complicated thoracic infections with this agent are rare in the pediatric population, they have been increasing in adults. Streptococcus anginosus has a high capacity to form abscess and empyema, requiring different therapeutic approaches when compared to complicated pneumonia caused by other agents.

RESUMEN

BACKGROUND: Simultaneous infection in tuberculosis (TB) is rare. The mixed infection between Streptococcus anginosus group (SAG) and M. tuberculosis (MTB) has not been reported in children. The aim of this report was to describe a pediatric case with a pulmonary abscess caused by the duality SAG-MTB co-infection. CASE PRESENTATION: An 11-year-old boy with an acute onset of throbbing pain of two-day evolution located in the anterior chest wall. The patient reported a history of fever, cough and rhinorrhea during the last seven days. An anterior chest radiography revealed a heterogenic opacity at the lower right lobe while the lateral projection showed an obliteration at the anterior diaphragmatic insertion. Parenteral Ceftriaxone (100 mg/kg/day) and Dicloxacillin (200 mg/kg/day) was started. The abscess was subsequently drained and analyzed. After a year of follow-up, the patient remained asymptomatic. CONCLUSION: This case represents the first reported case of pulmonary co-infection involving MTB and SAG in an immunocompetent pediatric patient.

RESUMO Objetivo: Alertar para a patogenicidade do Streptococcus anginosus que, apesar de raro em pediatria, pode causar infeções graves que necessitam de tratamento invasivo e antibioterapia de longo curso para obter um melhor prognóstico. Descrição do caso: Criança de seis anos, com atraso do desenvolvimento psicomotor, avaliado no serviço de urgência por febre e dificuldade respiratória. O exame físico, juntamente com os exames complementares, revelou uma pneumonia complicada com empiema no hemitórax esquerdo, tendo iniciado antibioterapia e sido submetido à drenagem do líquido pleural. Foi identificado Streptococcus anginosus nesse líquido. No 11º dia de doença, a criança agravou o seu estado clínico, com recidiva da febre, hipoxemia e dificuldade respiratória. Considerando-se o microrganismo identificado, o paciente foi submetido à decorticação pulmonar por videotoracoscopia, com boa evolução clínica posterior. Comentários: Streptococcus anginosus é uma bactéria comensal da cavidade oral humana, que pode causar infecções sistêmicas graves. Apesar de serem raros os casos descritos em pediatria, têm sido cada vez mais descritas infecções torácicas complicadas em adultos. Esse microrganismo também tem a capacidade de formar abcessos e empiemas, que precisam de intervenções terapêuticas diferentes, quando comparados a pneumonias complicadas causadas por outros agentes.

RESUMEN

A 15-year-old, mixed breed, male horse was attended with a history of multiple abscesses in the cervical region with a three-year evolution. Upon admission, three fistulous tracts with drainage of purulent secretions in the cervical region, low body score, restriction of cervical movements, and painful sensitivity to palpation were observed. The horse was diagnosed with osteomyelitis secondary to Streptococcus equi infection. The initial treatment was antibiotic therapy and local curative. Owing to the lack of response, surgical debridement was performed. An initial favorable response was observed; however, after 4 months, drainage recurred, and the animal was euthanized. A post-mortem computed tomography scan was performed to obtain details of the injury. Cervical osteomyelitis is rare, and its occurrence through hematogenous spread in adult horses and the tomographic findings had not been reported previously. The long period of evolution, difficulty in performing an aggressive debridement, and the presence of multi-drug resistant bacteria contributed to the negative outcome.(AU)


Um equino macho, sem raça definida, de 15 anos de idade, foi atendido com histórico de múltiplos abscessos cervicais com evolução de três anos. Na admissão, foram observados: três trajetos fistulosos com drenagem de material purulento na região cervical; baixo escore corporal; restrição de movimentos cervicais; e sensibilidade dolorosa à palpação da região. Foi diagnosticada osteomielite vertebral cervical secundária à infecção por Streptococcus equi. O tratamento inicial consistiu na administração de antibióticos e curativo local. Na ausência de resposta à terapia, realizou-se o debridamento cirúrgico. Inicialmente, obteve-se uma resposta favorável, entretanto, após quatro meses, houve recidiva da lesão e o animal foi submetido à eutanásia. Realizou-se tomografia computadorizada no post mortem para detalhamento da lesão. A osteomielite vertebral cervical é rara, e sua ocorrência por meio de disseminação hematógena em animais adultos não foi previamente reportada. O longo período de evolução, aliado à dificuldade de realização de um debridamento agressivo, e a característica multirresistente do agente etiológico contribuíram para o desfecho negativo do caso.(AU)

RESUMEN

This report describes the post-bariatric-surgery evolution of an obese patient who had low adherence to the diet and micronutrient supplementation. Four years after two bariatric surgeries, the patient was admitted due to transient loss of consciousness, slow thinking, anasarca, severe hypoalbuminemia, in addition to vitamin and mineral deficiencies. She had subcutaneous foot abscess but did not present fever. Received antibiotics, vitamins A, D, B12, thiamine, calcium, and parenteral nutrition. After hospitalization (twenty-eight days), there was a significant body weight reduction probably due to the disappearance of clinical anasarca. Parenteral nutrition was suspended after twenty-five days, and the oral diet was kept fractional. After hospitalization (weekly outpatient care), there was a gradual laboratory data improvement, which was now close to the reference values. Such outcome shows the need for specialized care in preventing and treating nutritional complications after bariatric surgeries as well as clinical manifestations of infection in previously undernourished patients.

RESUMEN

AIMS: The EURO-ENDO registry aimed to study the management and outcomes of patients with infective endocarditis (IE). METHODS AND RESULTS: Prospective cohort of 3116 adult patients (2470 from Europe, 646 from non-ESC countries), admitted to 156 hospitals in 40 countries between January 2016 and March 2018 with a diagnosis of IE based on ESC 2015 diagnostic criteria. Clinical, biological, microbiological, and imaging [echocardiography, computed tomography (CT) scan, 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT)] data were collected. Infective endocarditis was native (NVE) in 1764 (56.6%) patients, prosthetic (PVIE) in 939 (30.1%), and device-related (CDRIE) in 308 (9.9%). Infective endocarditis was community-acquired in 2046 (65.66%) patients. Microorganisms involved were staphylococci in 1085 (44.1%) patients, oral streptococci in 304 (12.3%), enterococci in 390 (15.8%), and Streptococcus gallolyticus in 162 (6.6%). 18F-fluorodeoxyglucose positron emission tomography/computed tomography was performed in 518 (16.6%) patients and presented with cardiac uptake (major criterion) in 222 (42.9%) patients, with a better sensitivity in PVIE (66.8%) than in NVE (28.0%) and CDRIE (16.3%). Embolic events occurred in 20.6% of patients, and were significantly associated with tricuspid or pulmonary IE, presence of a vegetation and Staphylococcus aureus IE. According to ESC guidelines, cardiac surgery was indicated in 2160 (69.3%) patients, but finally performed in only 1596 (73.9%) of them. In-hospital death occurred in 532 (17.1%) patients and was more frequent in PVIE. Independent predictors of mortality were Charlson index, creatinine > 2 mg/dL, congestive heart failure, vegetation length > 10 mm, cerebral complications, abscess, and failure to undertake surgery when indicated. CONCLUSION: Infective endocarditis is still a life-threatening disease with frequent lethal outcome despite profound changes in its clinical, microbiological, imaging, and therapeutic profiles.

RESUMEN

SUMMARY This report describes the post-bariatric-surgery evolution of an obese patient who had low adherence to the diet and micronutrient supplementation. Four years after two bariatric surgeries, the patient was admitted due to transient loss of consciousness, slow thinking, anasarca, severe hypoalbuminemia, in addition to vitamin and mineral deficiencies. She had subcutaneous foot abscess but did not present fever. Received antibiotics, vitamins A, D, B12, thiamine, calcium, and parenteral nutrition. After hospitalization (twenty-eight days), there was a significant body weight reduction probably due to the disappearance of clinical anasarca. Parenteral nutrition was suspended after twenty-five days, and the oral diet was kept fractional. After hospitalization (weekly outpatient care), there was a gradual laboratory data improvement, which was now close to the reference values. Such outcome shows the need for specialized care in preventing and treating nutritional complications after bariatric surgeries as well as clinical manifestations of infection in previously undernourished patients.


RESUMO Este relato descreve a evolução pós-cirurgia bariátrica de uma paciente obesa que apresentou baixa adesão à dieta e suplementação de micronutrientes. Quatro anos após duas cirurgias bariátricas, a paciente foi internada por perda transitória de consciência, raciocínio lento, anasarca, hipoalbuminemia grave, além de deficiências vitamínicas e minerais. Apresentava abscesso subcutâneo no pé, mas não apresentava febre. Recebeu antibióticos, vitaminas A, D, B12, tiamina, cálcio e nutrição parenteral. Após a internação (28 dias) houve redução significativa do peso corporal, provavelmente devido ao desaparecimento clínico da anasarca. A nutrição parenteral foi suspensa após 25 dias e a dieta oral foi mantida fracionada. Após a internação (atendimento ambulatorial semanal) houve uma melhora gradativa dos dados laboratoriais, que estavam próximos dos valores de referência. Tal desfecho mostra a necessidade de cuidados especializados na prevenção e tratamento de complicações nutricionais após cirurgias bariátricas, bem como manifestações clínicas de infecção em pacientes previamente desnutridos.
