ABSTRACT

Introducción: la sepsis tardía por estafilococo coagulasa negativo (SCoN) es una causa común de morbimortalidad en la unidad neonatal. Los SCoN son los microorganismos más frecuentemente involucrados con aproximadamente el 50% de los casos. El objetivo de este estudio es analizar la incidencia y las características de los neonatos portadores de sepsis tardía por SCoN. Materiales y métodos: se realizó un estudio descriptivo, longitudinal, retrospectivo. Se utilizaron las bases de datos del laboratorio de microbiología del hospital y las historias clínicas electrónicas para obtener la información. El período de estudio analizado fueron los años 2018 y 2019 en la unidad de cuidados intensivos e intermedios de recién nacidos del Centro Hospitalario Pereira Rossell. Resultados: obtuvimos una incidencia de 2,5% de los ingresos a cuidados intensivos e intermedios (25 pacientes). La edad gestacional al nacer fue de 28 semanas (25,0-35,0) y la mediana del peso fue de 1.070 g (730,0-2.365,0). La media de edad gestacional posmenstrual al momento del diagnóstico fue de 32,92±7,921 semanas. Por sospecha de sepsis precoz, 17 pacientes habían recibido un curso de antibióticos previo. El signo clínico más frecuentemente observado fue el deterioro del estado general, en 11 pacientes, seguido de distensión abdominal en 6 y fiebre en 5. Dentro de los SCoN, el más frecuentemente aislado fue el Staphylococcus epidermidis (13 pacientes); 22 pacientes recibieron tratamiento, 18 de ellos con vancomicina-meropenem y 4 con monoterapia con vancomicina. Conclusión: estos patógenos representan una causa importante de morbimortalidad en la unidad neonatal, particularmente en pacientes que presentan mayor gravedad y mayor necesidad de soporte vital. Se necesitan pautas claras de interpretación del rol de estos microorganismos y de abordaje de pacientes con riesgo de sepsis tardía, incluyendo el tratamiento antibiótico empírico.


Introduction: Coagulase Negative Staphylococci (CoNS) late onset sepsis is a common cause of morbidity and mortality in the neonatal intensive care unit (NICU). CoNS are the most frequently isolated microorganisms and total 50% of cases. The objective of this study is to analyze the incidence and characteristics of newborns carriers of late onset CoNS. Materials and methods: we performed a descriptive, retrospective, longitudinal study. Data was obtained from the hospital's microbiology laboratory database and electronic medical records. Patients included were those admitted to NICU during the period between 2018 and 2019. Results: we obtained an incidence of 2.5% of patients admitted to the NICU (25 patients). Median gestational age at birth was 28 weeks 25.0-35.0 and median birth weight was 1.070 g 730.0-2365.0. Mean gestational age at the time of diagnosis was 32.92±7.921 weeks. 17 patients had received an antibiotics course at birth because of early onset sepsis suspicion. The most frequently observed clinical symptom was deterioration of general condition, 11 patients, followed by abdominal distention in 6 and fever in 5. Among CoNS, the most frequently isolated pathogen was Staphylococcus epidermidis (13 patients). 22 patients received treatment, 18 a combination of vancomycin and meropenem and 4 received vancomycin monotherapy. Conclusion: these pathogens are a common cause of morbidity and mortality in the newborn intensive care unit, particularly in patients with more serious conditions and in those who require more advanced life support measures. Clearer interpretation of their role is needed as well as to determine a proper approach to patients at risk of late onset sepsis, including empiric antibiotic treatment.


Sepse tardia para Staphylococcus coagulase negativa (SCoN) é uma causa comum de morbidade e mortalidade na unidade neonatal. SCoNs são os microrganismos mais frequentemente envolvidos e representam aproximadamente 50% dos casos. O objetivo deste estudo é analisar a incidência e as características de neonatos com sepse tardia por SCoN. Materiais e métodos: foi realizado um estudo descritivo, longitudinal e retrospectivo. Usamos os bancos de dados do laboratório de microbiologia e prontuários médicos eletrônicos de nosso hospital para obter as informações. O período de estudo analisado foi de 2018 e 2019 na unidade de terapia intensiva e intermediária para recém-nascidos do Centro Hospitalar Pereira Rossell. Resultados: obtivemos uma incidência de 2,5% de internações em Terapia Intensiva e Intermediária (25 pacientes). A idade gestacional ao nascer foi de 28 semanas 25,0-35,0 e o peso médio foi de 1070g 730,0-2365,0. A média da idade gestacional pós-menstrual no momento do diagnóstico foi de 32,92 ± 7,921 semanas. 17 pacientes haviam recebido um curso anterior de antibióticos por suspeita de sepse precoce. O sinal clínico mais frequentemente observado foi deterioração do estado geral em 11 pacientes, seguido por distensão abdominal em 6 e febre em 5. Dentre os SCoN, o mais isolado foi o Staphylococcus Epidermidis (13 pacientes). 22 pacientes receberam tratamento, 18 deles com Vancomicina-Meropenem e 4 com Vancomicina em monoterapia. Conclusão: esses patógenos representam uma importante causa de morbimortalidade na unidade neonatal, principalmente em pacientes com maior gravidade e maior necessidade de suporte de vida. Orientações claras são necessárias para interpretar o papel desses microrganismos e para abordar pacientes com risco de sepse tardia, incluindo tratamento com antibióticos.

ABSTRACT

Los estafilococos coagulasa negativos son microorganismos frecuentemente aislados cuya significancia clínica puede ser difícil de establecer por su carácter de comensales habituales de la piel. En la población neonatal estos patógenos han ido adquiriendo mayor protagonismo debido a la sobrevida de pacientes mas prematuros que en el pasado, así como sus necesidades de tratamiento, que determinan mayores tiempos de estadía hospitalaria. Estos elementos representan factores de riesgo también para el desarrollo de endocarditis en estos pacientes, particularmente debido a la utilización de catéteres intravasculares centrales por tiempo prolongado. En este caso clínico se presenta un paciente pretérmino severo que presentó una endocarditis a estafilococo coagulasa negativo a partir del cual discutiremos las características de las infecciones por estos microorganismos, las características de la endocarditis infecciosa en el recién nacido pretérmino y la utilización de antibióticos en estos pacientes, así como algunos elementos asociados a la vigilancia activa en el uso de antibióticos.


Coagulase negative staphylococcus (CoNS) are commonly isolated microorganisms whose clinical importance may be difficult to establish due to their role as part of our usual skin microbiota. These pathogens have gained relevance in neonatal population due to an improvement in neonatal care that determine longer survival rates and hospitals stays. Neonatal endocarditis is also affected by these microorganisms and particularly by the use of central intra vascular lines for long periods of time. In this clinical case we introduce a severe preterm patient who developed a CoNS endocarditis and discuss the characteristics of CoNS infections and endocarditis in preterm newborns as well as some antibiotic vigilance principles.


Os estafilococos coagulase negativos são microrganismos frequentemente isolados, cujo significado clínico pode ser difícil de estabelecer devido ao seu caráter de comensais cutâneos comuns. Na população neonatal, esses patógenos vêm adquirindo maior destaque devido à sobrevida de pacientes mais prematuros do que no passado, bem como suas necessidades de tratamento, as quais determinam tempos de internação mais longos. Esses elementos também representam fatores de risco para o desenvolvimento de endocardite nesses pacientes, principalmente pelo uso prolongado de cateter intravascular central. Neste caso clínico apresentaremos um paciente pré-termo grave que apresentou endocardite estafilocócica coagulase-negativa a partir do qual discutiremos as características das infecções por esses microrganismos, as características da endocardite infecciosa no recém-nascido pré-termo e o uso de antibióticos nesses pacientes bem como alguns elementos associados à vigilância ativa no uso de antibióticos.

ABSTRACT

RESUMEN La introducción de los antibióticos en el siglo pasado ha sido uno de los ejemplos que brinda la historia de intervenciones médicas que cambiaron drásticamente la esperanza de vida de la población. La época dorada de los antibióticos, cuando la aparición de nuevas moléculas era lo habitual, ha dado paso a otra de sequía, en la que es raro el desarrollo de este grupo farmacológico debido al largo período de tiempo que requieren las investigaciones de nuevos fármacos, su elevado costo y al aumento de las exigencias regulatorias. Este progreso médico ganado en décadas pasadas, está amenazado por el aumento de la resistencia de las bacterias a los antibióticos; constituye un grave riesgo mundial por lo que requiere una mayor atención y la coherencia a nivel internacional, nacional y regional. La resistencia bacteriana tiene un gran impacto microbiológico, terapéutico, económico, epidemiológico y en la salud pública; cuesta dinero, medios de subsistencia, vidas humanas y amenaza con socavar la eficacia de los programas de atención a la salud. La presente revisión bibliográfica propone reflexionar sobre los aspectos más significativos del desarrollo de los antibióticos y su impacto en la sociedad.


ABSTRACT The introduction of antibiotics in the last century has been one of the examples that history provides of medical interventions that drastically changed the life expectancy of the population. The golden age of antibiotics, where the appearance of new molecules was what usual, has given way to another of drought, in which the development of this pharmacological group is rare due to the long period of time required for research into new drugs, their high cost and the increase in regulatory requirements. This medical progress gained in past decades is threatened by the increase in the resistance of bacteria to antibiotics, constituting a serious global risk for which it requires greater attention and coherence at the international, national and regional levels. Bacterial resistance has a great microbiological, therapeutic, economic, epidemiological and public health impact; it costs money, livelihoods, human lives, and threatens to undermine the effectiveness of health care programs. This bibliographic review proposes to reflect on the most significant aspects of the development of antibiotics and their impact on society.

ABSTRACT

Resumen La enfermedad de Whipple es una enfermedad multisistémica crónica, causada por la bacteria Tropherima whipplei. Se han descripto aproximadamente 1200 casos en la literatura. La incidencia mundial se estima en 9.8 casos por millón de personas. Los datos provenientes de Sudamérica y Europa muestran que afecta a varones de mediana edad. Se cree que los factores inmunológicos del huésped son los que influyen en el curso de la infección y no el genotipo del agente. Dado que las características clínicas no suelen ser específicas y el espectro de manifestaciones en órganos individuales puede ser subestimado, el diagnóstico sigue siendo muy difícil. Presentamos un caso confirmado por histopatología con compromiso multisistémico. Consideramos importante su difusión dados los escasos casos documentados en Sudamérica y la relevancia de tener presente la sospecha diagnóstica para el abordaje terapéutico precoz que mejora el pronóstico de esta rara enfermedad.


Abstract Whipple's disease is a chronic mutisystem disease caused by the bacteria Tropherima whipplei. Approximately 1200 cases have been described in the literature. The worldwide incidence is estimated at 9.8 cases per million people. Data from South America and Europe show that it affects middle-aged males. It is believed that host immunological factors rather than agent genotypic traits influence the course of the infection. Since the clinical characteristics are usually nonspecific and the wide spectrum of manifestations in individual organs may be underestimated, the diagnosis remains challenging. We present a case with multisystem compromise confirmed by histopathology. We consider its publication important given the few cases documented in South America and the relevance of bearing in mind the importance of an early diagnosis for a prompt treatment that improves the prognosis of this rare disease.

ABSTRACT

The rationale for the antibiotic treatment of viral community-acquired pneumonia (CAP) in adults was analyzed to develop a clinical reference standard for this condition. Clinical data from 166 patients diagnosed with viral pneumonia across 14 hospitals in Beijing from November 2010 to December 2017 were collected. The indications for medications were evaluated, and the rationale for the use of antibiotics was analyzed. A total of 163 (98.3%) patients with viral pneumonia were treated with antibiotics. A combination of C-reactive protein (CRP) and procalcitonin (PCT) was used as markers to analyze the possible indications for antibiotic use. With threshold levels set at 0.25 µg/L for PCT and 20 mg/L for CRP, the rate of unreasonable use of antibiotics was 55.2%. By contrast, at a CRP level threshold of 60 mg/L, the rate of antibiotic misuse was 77.3%. A total of 39 of the 163 (23.9%) patients did not meet the guidelines for drug selection for viral CAP in adults. The unreasonable use of antibacterial drugs for the treatment of viral CAP in adults is a serious concern. Clinicians must reduce the unnecessary use of antibiotics.

ABSTRACT

OBJECTIVE@#To analyze the characteristics, prognosis and risk factors of bloodstream infection in patients with hematological malignancies in the tropics, so as to provide evidence for the prevention and treatment of bloodstream infection.@*METHODS@#The clinical features, blood culture results and prognosis of patients with bloodstream infection in patients with hematological malignancies admitted to Hainan Hospital of PLA General Hospital were retrospectively studied.@*RESULTS@#The most common primary infection site of the 81 patients with hematological malignancies was lung (46.91%), followed by PICC (11.11%). The detection rate of Gram-positive bacteria and Gram-negative bacteria in the blood culture was 60.98% and 30.02%, respectively. Coagulase-negative staphylococci was the most common Gram-positive bacteria resulting in bloodstream infection in our study. Of the Gram-negatives, Klebsiella pneumoniae (34.38%) was predominant, followed by Escherichia coli (18.75%) and Pseudomonas aeruginosa (18.75%). Gram-positive bacteria was highly sensitive (100%) to vancomycin, linezolid and tigecycline. Study showed that Gram-negative bacteria had low sensitive to quinolones, in particular, the resistance rate of Escherichia coli to quinolones was as high as 83.33%. In terms of overall survival (OS), the 30-days OS of patients with Gram-negative and Gram-positive septicemia was 77.42% and 92.00%, respectively. There was no statistically significant difference between the two groups. Multivariate analysis revealed that septic shock (P=0.001, RR=269.27) was an independent risk factor for 30-day mortality, and remission status (P=0.027, RR=0.114) was an independent predictor of a favourable outcome of bloodstream infection in patients with hematological malignancies.@*CONCLUSION@#Gram-positive bacteria are the main pathogens causing bloodstream infections in patients with hematological malignancies in the tropics. Improving the care of PICC is an important measure to reduce the incidence of bloodstream infection in patients with hematological malignancies in the tropics. A correct treatment relieving disease and effective prevention and treatment of septic shock can reduce mortality of patients with bloodstream infection in patients with hematological malignancies in the tropics.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of sepsis risk calculator (SRC) in guiding antibiotic use in neonates with suspected early-onset sepsis (EOS).@*METHODS@#A total of 284 neonates with a gestational age of ≥ 35 weeks were enrolled as the control group, who were hospitalized in the Children's Hospital of Chongqing Medical University from March to July, 2019 and were suspected of EOS. Their clinical data were retrospectively collected and the use of antibiotics was analyzed based on SRC. A total of 170 neonates with a gestational age of ≥ 35 weeks were enrolled as the study group, who were admitted to the hospital from July to November, 2020 and were suspected of EOS. SRC was used prospectively for risk scoring to assist the decision making of clinical antibiotic management. The two groups were compared in terms of the rate of use of antibiotics, blood culture test rate, clinical outcome, and adherence to the use of SRC.@*RESULTS@#Compared with the control group, the study group had a significantly higher SRC score at birth and on admission (@*CONCLUSIONS@#The use of SRC reduces the rate of empirical use of antibiotics in neonates with suspected EOS and does not increase the risk of adverse outcomes, and therefore, it holds promise for clinical application.

ABSTRACT

OBJECTIVE@#To analyze the clinical data of children with invasive pneumococcal disease (IPD) or noninvasive pneumococcal disease (NIPD), and to provide a reference for clinical diagnosis and treatment.@*METHODS@#A retrospective analysis was performed on the medical data and the drug susceptibility test results of isolated strains of 518 children who were hospitalized due to @*RESULTS@#The children with IPD had a median age of 2.2 years, and the children aged ≤5 years accounted for 80.0%. For the children with IPD, the main type of infection was meningitis which was observed in 19 children (54.3%), and the most common underlying disease was hematological malignancy in 8 children (22.9%); 14 children (40.0%) were admitted to the pediatric intensive care unit (PICU), 18 children (51.4%) experienced complications, and 8 children (22.9%) died. For the children with NIPD, the median age was 1.2 years; the main type of infection was pneumonia in 429 children (88.8%), and the most common underlying disease was congenital heart disease in 60 children (12.4%); 60 children (12.4%) were admitted to the PICU, 102 children (21.1%) experienced complications, and 11 children (2.3%) died. The IPD group had significantly higher incidence rate of complications, PICU admission rate, and mortality rate than the NIPD group (@*CONCLUSIONS@#SP infection is common in children under 5 years of age, and the children with underlying diseases including hematological malignancy are at high risk for IPD. Although the complication rate, PICU admission rate, and mortality rate of NIPD children are lower than those of IPD children, they still cannot be ignored. Penicillin may be used as an empirical treatment for children with NIPD, but not for those with IPD.

ABSTRACT

OBJECTIVES: Antimicrobial stewardship programs (ASPs) comprise coordinated interventions designed to improve antimicrobial use. Understanding the current structure of ASP hospitals will support interventions for the improvement of these programs. This study aimed to describe the status of ASPs in hospitals in São Paulo, Brazil. METHODS: A cross-sectional survey was conducted on the ASPs of hospitals in the state of São Paulo from March to July 2018. Through interviews by telephone or e-mail, we queried which components of the Infectious Diseases Society of America/Society for Healthcare Epidemiology of America and Centers for Disease Control and Prevention guidelines were implemented. RESULTS: The response rate was 30% (28/93 hospitals), and 26 hospitals (85%) reported having a formal ASP. The most frequently implemented strategies were antimicrobial surgical prophylaxis guidelines (100%), empiric sepsis guidelines (93%), and the presence of ASP team members during bedside rounds (96%). The least commonly implemented strategies included prior authorization for all antimicrobials (11%), pharmacokinetic monitoring, and an adjustment program for patients on IV aminoglycosides (3%). Regarding the metrics of the ASP, the most common indicator was the rate of antimicrobial resistance (77%). Eighteen hospitals evaluated antimicrobial consumption using defined daily dose, and only 29% evaluated the days of therapy; 61% of hospitals reported their results to the hospital administration and 39% to the prescribers. CONCLUSIONS: Most hospitals have a formal and active ASP, but with timely actions. We observed inconsistencies between what program leaders understand as the main objective of ASP and the metrics used to evaluate it. Part of the effort for the next few years should be to improve program evaluation metrics and to provide feedback to physicians and hospital leadership.

ABSTRACT

A mastite é uma patologia relativamente frequente na mulher que amamenta. Surge maioritariamente nas primeiras seis semanas após o parto (prevalência entre 75-95% antes do bebé completar os três meses de vida), podendo, contudo, ocorrer ao longo de todo o período da amamentação. Apresenta-se clinicamente com mastalgia, eritema e edema mamário, linfonodomegalia axilar, febre, calafrios, mal-estar e prostração. Entretanto, o quadro clínico completo pode não estar presente em todos os casos. A técnica incorreta de amamentação provoca as microlesões mamáriasque são fatores associados à mastite, inicialmente, e esta quando não recebe tratamento adequado pode evoluirpara os abscessos mamários, que são caracterizados clinicamente por nodulação palpável ou não, flutuante, parcialmente circunscrita, geralmente no quadrante superior lateral da mama afetada. O microrganismo mais envolvido é o Staphylococcus aureus. O diagnóstico diferencial envolve principalmente outras causas não infecciosas de mastite, por exemplo a granulomatosa com reação a corpo estranho (piercing, implantes de silicone) e também malignidade. A ultrassonografia é um método bastante útil na investigação inicial daqueles quadros com suspeita de desenvolvimento de tal complicação e possibilita de maneira segura o tratamento minimamente invasivo e a obtenção de amostra para analise laboratorial. Isto permite a escolha de antibioticoterapia direcionada para os microorganismos causadores.


Mastitis is a relatively common condition in breastfeeding women. It appears mostly in the first six weeks after delivery (prevalence between 75-95% before the baby is three months old), however, it can occur throughout the entire period of breastfeeding. It may present clinically with mastalgia, erythema and breast edema, axillary lymph node enlargement, fever, chills, malaise and prostration. However, the complete clinical picture may not be present in all cases. The incorrect breastfeeding technique causes breast microlesions which are factors associated with mastitis, initially, and when it does not receive adequate treatment it can evolve for breast abscesses, which are characterized clinically by palpable or not, floating, partially circumscribed nodulation, usually in the upper lateral quadrant of the affected breast. The most involved microorganism is Staphylococcus aureus. The differential diagnosis mainly involves other non-infectious causes of mastitis, for example granulomatous with a foreign body reaction (piercing, silicone implants) and also malignancy. Ultrasonography is a very useful method in the initial investigation of those conditions suspected of developing such a complication, and it safely allows minimally invasive treatment and obtaining a sample for laboratory analysis. This allows the choice of antibiotic therapy directed at the causative microorganisms.

ABSTRACT

La tuberculosis es la primera causa de mortalidad infectocontagiosa a nivel mundial. La tuberculosis pulmonar corresponde a la presentación más frecuente, sin embargo, el 15 % de los casos cursan con infección extrapulmonar, siendo raro el compromiso amigdalino. Este reporte de caso describe a un paciente de 39 años con odinofagia recurrente secundaria a amigdalitis por Mycobacterium tuberculosis, un raro caso de tuberculosis extrapulmonar. La amigdalitis es una infección leve y frecuente de la vía aérea superior, que responde adecuadamente al manejo antibiótico; sin embargo, cuadros recurrentes y prolongados, manifestaciones atípicas o pobre respuesta a la antibioticoterapia son características que obligan a la búsqueda de diagnósticos diferenciales, lo que lleva a considerar la presencia de Mycobacterium tuberculosis como agente etiológico, especialmente en países con alto índice de tuberculosis como Colombia


Tuberculosis is the leading cause of infectious mortality worldwide. The pulmonary one corresponds to the most frequent presentation, however up to 15% of tuberculosis cases present extrapulmonary involvement, tonsillar tuberculosis being rare. The following is a case report of a 39-year-old patient with recurrent odynophagia secondary to Mycobacterium tuberculosis tonsillitis, a rare form of extrapulmonary tuberculosis. Tonsillitis is a benign and extremely common infection of the upper airway. Such patients benefit from systemic antibiotics, although, recurrent episodes, prolonged odynophagia, atypical manifestations, or poor response to antimicrobial therapy forces consideration of diagnostic possibilities other than the obvious, including Mycobacterium tuberculosis as the etiological agent, especially in countries with the highest rates of tuberculosis.

ABSTRACT

Objective:To identify the prevalence of klebsiella pneumoniae and to analyze the factors related to the infection by this bacterium in a private hospital in northeastern Brazil. Method: descriptive retrospective documentary study, carried out with patients who developed infection in the year 2017 (n: 64). Sociodemographic and infection information was collected. The data was processed in SPSS 20.0. The project was approved by the ethics committee. Results: the most prevalent topographic site was the urinary tract (34; 56.7%). the main risk factor for triggering klebsiella pneumoniae infection was the use of mechanical ventilation, presenting a risk of 43.8% for the appearance of infections by this microorganism. Higher resistance was found for the piperacillin / tazobactam 52 antimicrobial (82.5%). Conclusion: because of the high resistance to antibiotics and the great potential of klebsiella contamination, measures should be taken to minimize the high level of contamination and, especially, the negative prognosis for the patient

ABSTRACT

ABSTRACT Purpose: The aims of this study were to characterize alpha-hemolytic streptococci among isolates from cases of infectious endophthalmitis and keratitis and to determine their distributions. Methods: The sample included 27 and 35 nonduplicated isolates of alpha-hemolytic streptococci recovered from patients with infectious endophthalmitis (2002-2013) and keratitis (2008-2013), respectively. Isolates were identified by the optochin susceptibility and bile solubility tests, using a biochemical identification system. The minimum inhibitory concentration was determined by the broth microdilution method. Molecular identification was performed by analyses of three constitutive genes and the complementary multilocus sequence. The molecular epidemiology of Streptococcus pneumoniae was investigated using multilocus sequence typing, and the presence of the capsular polysaccharide-encoding gene was assessed using conventional polymerase chain reaction. Outcomes were evaluated using the patients' medical records. Results: Phenotypic tests differentiated S. pneumoniae from other alpha-hemolytic streptococci, consistent with later molecular identifications. Streptococcus oralis was significantly prevalent among the endophthalmitis isolates, as was S. pneumoniae in the keratitis isolates. High levels of susceptibility to antibiotics were observed, including vancomycin, cephalosporins, and fluoroquinolones. High genetic variability was detected among the 19 S. pneumoniae strains, with 15 predicted to be encapsulated. The medical records of patients with infectious endophthalmitis were reviewed (n=15/27; 56%), and final visual acuity was assessed in 12 cases (44%). Many patients progressed to a final visual acuity state of "no light perception" (6/12; 50%), "light perception" (3/12; 25%), or "hand motion" (1/12; 8%). The medical records of patients with infectious keratitis were also reviewed (n=24/35; 69%), and final visual acuity was assessed in 18 cases (51%). Similarly, most patients progressed to a final visual acuity state of "no light perception" (6/18; 33%), "light perception" (1/18; 6%), or "hand motion" (6/18; 33%). Overall, the majority of patients progressed to a final visual acuity state of "no light perception" (12/30), "light perception" (4/30), or "hand motion" (7/30). Conclusions: The distribution of alpha-hemolytic streptococci in ocular infections suggested the presence of a species-specific tissue tropism. The prognoses of patients with ocular streptococcal infections were highly unfavorable, and antibiotic resistance did not contribute to the unfavorable clinical progressions and poor outcomes.


RESUMO Objetivo: O objetivo deste estudo foi caracterizar os estreptococos alfa-hemolíticos isolados de endoftalmite infecciosa e ceratite e determinar sua distribuição. Métodos: A amostra incluiu 27 e 35 isolados não-duplicados de estreptococos alfa-hemolíticos recuperados de pacientes com endoftalmite infecciosa (2002-2013) e ceratite (2008-2013), respectivamente. Os isolados foram identificados pelos testes de suscetibilidade à optoquina e bile solubilidade, utilizando um sistema de identificação bioquímica. A concentração inibitória mínima foi determinada pelo método de microdiluição em caldo. A identificação molecular foi realizada pela análise de três genes constitutivos e análise complementar de sequências multilocus. A epidemiologia molecular do Streptococcus pneumoniae foi investigada por tipagem de sequência multilocus, e a presença do gene codificador do polissacarídeo capsular foi avaliada por reação em cadeia da polymerase convencional. Os resultados foram avaliados utilizando os prontuários médicos dos pacientes. Resultados: Os testes fenotípicos diferenciaram S. pneumoniae dos outros estreptococos alpha-hemolíticos, consistentes com identificações moleculares posteriores. S. oralis foi significativamente prevalente entre os isolados de endoftalmite, assim como S. pneumoniae nos isolados de ceratite. Foram observados altos níveis de suscetibilidade a antibióticos, incluindo vancomicina, cefalosporinas e fluoroquinolonas. Alta variabilidade genética foi detectada entre as 19 cepas de S. pneumoniae, com 15 previstas para serem encapsuladas. Os prontuários médicos dos pacientes com endoftalmite infecciosa foram revisados (n=15/27; 56%), e a acuidade visual final foi avaliada em 12 casos (44%). Muitos pacientes evoluiram para um estado final de acuidade visual de "sem percepção luminosa" (6/12; 50%), "percepção luminosa" (3/12; 25%) ou "movimentos de mãos" (1/12; 8%). Também foram revisados os prontuários médicos dos pacientes com ceratite infecciosa (n=24/35; 69%), e a acuidade visual final foi avaliada em 18 casos (51%). Da mesma foram, a maioria dos pacientes evoluiu para um estado final de acuidade visual de "sem percepção luminosa" (6/18; 33%), "percepção luminosa" (1/18; 6%) ou "movimentos de mãos" (6/18; 33%). No geral, a maioria dos pacientes evoluiu para um estado final de acuidade visual de "sem percepção luminosa" (12/30), "percepção luminosa" (4/30) ou "movimentos de mãos" (7/30). Conclusões: A distribuição de estreptococos alfa-hemolíticos nas infecções oculares sugeriu a presença de um tropismo de tecido específico da espécie. Os prognósticos dos pacientes com infeções oculares por estreptococos foram altamente desfavoráveis e a resistência a antibióticos contribuiu não para as progressões clínicas des­favoráveis e os maus resultados.
