Streptococcus bovis infection of the central nervous system in adults: Report of 4 cases and literature review / Infección del sistema nervioso central por Streptococcus bovis en adultos: reporte de 4 casos y revisión de la literatura

Objectives: To describe the clinical features, history and association with intestinal disease in central nervous system (CNS) S. bovis infections. Methods: Four cases of S. bovis CNS infections from our institution are presented. Additionally a systematic literature review of articles published between 1975 and 2021 in PubMed/MEDLINE was conducted. Results: 52 studies with 65 cases were found; five were excluded because of incomplete data. In total 64 cases were analyzed including our four cases: 55 with meningitis and 9 with intracranial focal infections. Both infections were frequently associated with underlying conditions (70.3%) such as immunosuppression (32.8%) or cancer (10.9%). In 23 cases a biotype was identified, with biotype II being the most frequent (69.6%) and S. pasteurianus the most common within this subgroup. Intestinal diseases were found in 60.9% of cases, most commonly neoplasms (41.0%) and Strongyloides infestation (30.8%). Overall mortality was 17.1%, with a higher rate in focal infection (44.4% vs 12.7%; p=0.001). Conclusions: CNS infections due to S. bovis are infrequent and the most common clinical form is meningitis. Compared with focal infections, meningitis had a more acute course, was less associated with endocarditis and had a lower mortality. Immunosuppression and intestinal disease were frequent in both infections.(AU)

Introducción: Streptococcus bovis, una causa bien conocida de endocarditis asociada a cáncer colorrectal, es también una causa poco frecuente de infecciones del sistema nervioso central (SNC), incluyendo meningitis, abscesos cerebrales o empiema subdural. El objetivo de este estudio es describir las características clínicas, los antecedentes médicos y la asociación con la enfermedad intestinal en las infecciones por S. bovis en el SNC. Métodos: Describimos 4 infecciones por S. bovis en el SNC en nuestra Unidad y, a continuación, presentamos una revisión bibliográfica de los artículos publicados entre 1975-2021 en PubMed/MEDLINE. Resultados: Se encontraron 52 estudios con 65 casos; 5 se excluyeron por datos incompletos. En total se analizaron 64 casos incluyendo nuestros 4: 55 con meningitis y 9 con infecciones focales intracraneales. Ambas infecciones se asociaron con frecuencia a condiciones subyacentes (70,3%) como la inmunosupresión (32,8%) o el cáncer (10,9%). En 23 casos se identificó un biotipo, siendo el más frecuente el biotipo ii (69,6%), y dentro de ellos, S. pasteurianus. En el 60,9% de los casos se detectaron enfermedades intestinales, siendo las más frecuentes las neoplasias (41,0%) y la infestación por Strongyloides (30,8%). La mortalidad global fue del 17,1%, con una tasa mayor en la infección focal (44,4 frente a 12,7%; p=0,001). Conclusiones: Las infecciones del SNC debidas a S. bovis son poco frecuentes y la forma clínica más común es la meningitis. En comparación con las infecciones focales, la meningitis tiene un curso más agudo, está menos asociada a la endocarditis y tiene una menor mortalidad. La inmunosupresión y la enfermedad intestinal fueron frecuentes en ambas infecciones.(AU)

Assessment of Post-COVID Symptoms Using the C19-YRS Tool in a Cohort of Patients from the First Pandemic Wave in Northwestern Spain.

Introduction: The emergence or persistence of symptoms after acute SARS-CoV-2 infection has made it necessary to develop tools to detect them and assess their impact on patients' quality of life. One of these tools is the COVID-19 Yorkshire Rehabilitation Screening (C19-YRS) scale. We present the results of this tool in a cohort of first pandemic wave patients. Methods: A cross-sectional study of patients with confirmed SARS-CoV-2 infection from March to May 2020 in Lugo (northwestern Spain). C19-YRS was administered via phone 10 months after the acute infection to both former inpatients and outpatients. Electronic medical records were reviewed and relevant data from the acute episode were collected. The main outcome was the presence of impairment in different areas measured by the C19-YRS scale. Results: The answer rate was 63.2%. The mean age was 54 ± 16 years, 38.4% were male and 190 (42.9%) had some comorbidity. Eighty-seven patients (19.6%) required hospitalization and 10 (2.3%) required intensive care unit admission. Ten (3.5%) patients lost their job due to the pandemic. Two hundred seventy-six patients (62.3%) related any symptoms; fatigue (37.2%) and exertional dyspnea (33.4%) were the most common with significant worsening in both cases compared with the situation before the infection. Subgroup analysis showed that more symptom domains were impaired in women than men. Older patients, those with comorbidity and those who needed hospital admission, demanded more health resources after the acute infection. Discussion: C19-YRS is useful for the detection and quantification of symptoms after COVID-19 and provides relevant social, health, and occupational information.

Espondilodiscitis por Streptococcus suis: 2 nuevos casos y revisión bibliográfica / Streptococcus suis spondylodiscitis: 2 new cases and a literature review

IntroducciónLa infección por Streptococcus suis (S. suis) es una zoonosis poco descrita en nuestro país, que se relaciona con la exposición al ganado porcino o su carne. La forma de presentación más frecuente es la meningitis, mientras que la afectación de la columna vertebral es rara.MétodosPresentamos 2 casos de infección por S. suis y realizamos una revisión sistemática de los trabajos publicados sobre espondilodiscitis por S. suis entre enero de 1994 y mayo de 2020 con el objetivo de definir las características clínicas, sus factores predisponentes y su evolución.ResultadosSe describen 17 casos, el 76,5% varones con una edad media de 57,6 años, generalmente sin enfermedad de base asociada. El enolismo fue un factor presente en casi el 17,6% de los pacientes. Un 70,6% presentaron exposición a ganado porcino o su carne y un 20% heridas en manos. La duración media de los síntomas fue de 10,2 días y el segmento más afectado fue el lumbar. Un 70,6% cursó con meningitis. Todos se trataron con betalactámicos con una duración media de 53,2 días. Hubo una recidiva y ninguno falleció.ConclusiónExisten pocos casos de espondilodiscitis por S. suis en la literatura. Cuando ocurre, se asocia a otro tipo de infección en la mayoría de los casos. Presentan buena respuesta al tratamiento médico y buen pronóstico.

Neumonía comunitaria por Legionella pneumophila: estudio de 136 casos / Community acquired pneumonia by Legionella pneumophila: Study of 136 cases

Objetivo: La mayoría de los datos de la neumonía por Legionella en nuestro país proceden del área mediterránea, y apenas existen estudios en la zona del Noroeste. Con este trabajo se pretende conocer la situación de la infección en nuestro medio. Método: Estudio retrospectivo de todos los pacientes con antigenuria positiva para Legionella en el Hospital Universitario Lucus Augusti de Lugo desde 2001, año en que se introdujo la antigenuria como prueba diagnóstica en nuestro centro, hasta 2015. Se analizaron datos epidemiológicos, factores de riesgo, hallazgos clínicos, radiológicos, analíticos y evolutivos. Resultados: Se registraron 136 pacientes. Si comparamos los primeros 5años del estudio con los 5últimos, la incidencia aumentó de 10,9 a 64,5 casos/1.000.000, el número de peticiones de antigenuria se incrementó 3,4 veces, y con respecto a otras neumonías, Legionella pasó del 0,9 al 15% de ellas. La edad media fue de 64,1años, y el 84,6% fueron varones. El 74,3% tenían comorbilidades. Los varones fueron significativamente más jóvenes (62,7±16,6 vs 71,9±17,3) y consumían más alcohol (26,1% vs 0%) y tabaco (67,8% vs 14,3%). El 88,9% se diagnosticaron dentro de las primeras 72h y la mayoría recibió levofloxacino (95,6%). El 85% necesitaron ingreso hospitalario, el 11,7% en UCI y el 4,4% fallecieron. Conclusiones: Coincidiendo con la introducción de la antigenuria, se observa un aumento de incidencia de neumonía por Legionella en nuestra área sanitaria, con tasas en los últimos años que se sitúan entre las más altas de nuestro país. A pesar de tener pacientes con elevada edad media y un alto porcentaje de comorbilidades, la mortalidad fue reducida

Objective: Most of the data on Legionella pneumonia in our country come from the Mediterranean area, and there are few studies from the Northwest area. This study tries to assess the situation of this infection in this area. Method: Retrospective study of all patients with positive Legionella antigenuria treated at the University Hospital Lucus Augusti in Lugo (Spain) from 2001, the year in which this test was introduced in our centre, until 2015. We analysed epidemiological data, risk factors, clinical, radiological and biochemical findings, and clinical outcome. Results: The sampled included 136 patients. When comparing the first five years of the study with the last five, the incidence increased from 10.9 to 64.5 cases/1,000,000; the number of antigenuria requests increased 3.4 times, and compared to other pneumonia aetiologies Legionella increased from 0.9% to 15%. The mean age was 64.1years and 84.6% were males; 74.3% had comorbidities. Males were significantly younger (62.7±16.6 vs 71.9±17.3) and consumed more alcohol (26.1% vs 0%) and tobacco (67.8% vs 14.3%). Diagnosis was established within the first 72hours in 88.9% of cases and most received levofloxacin (95.6%). Hospitalisation was needed in 85% of cases, 11.7% in ICU and 4.4% died. Conclusions: After the introduction of antigenuria there was an increase in the incidence of Legionella pneumonia recorded in our health area. Its rate in recent years has been one of the highest in our country. Despite the fact that the patients had advanced age and comorbidities, mortality was low

Association between bacteremia due to Streptococcus gallolyticus subsp. gallolyticus (Streptococcus bovis I) and colorectal neoplasia: a case-control study.

BACKGROUND: The association between bacteremia by Streptococcus gallolyticus subsp. gallolyticus (SGG) and colorectal neoplasia (CRN) is well established but the frequency of the association varies widely in different studies. We conducted a case-control study to assess the association between SGG bacteremia and CRN. METHODS: An analysis of all SGG bacteremias was performed during the period 1988-2011. The frequency of CRN in patients with SGG bacteremia was compared with the frequency of CRN in a symptomatic control group of patients matched at a 1:2 ratio for gender and age (±3 years) without S. bovis bacteremia and personal history of CRN and with increased risk of CRN (by the presence of symptoms, signs, or test suspicious of colonic pathology or by family history of CRN). RESULTS: One hundred nine cases of SGG bacteremia were detected (mean age, 66 years; 87% male). Colonoscopy was performed in 98 cases, diagnosing 69 cases of CRN: 57 adenomas (39 advanced adenomas) and 12 invasive carcinomas. Only 4 cases had suspected CRN before the blood culture. The prevalence of CRN was higher in patients with SGG bacteremia than in the 196 control patients (70% vs 32%; odds ratio [OR], 5.1; 95% confidence interval [CI], 3.0-8.6). This difference was not significant when comparing nonadvanced adenomas (19% vs 12%), but we found significant differences in advanced adenomas (40% vs 16%; OR, 3.5; 95% CI, 2.0-6.1) and invasive carcinomas (12% vs 5%; OR, 2.9; 95% CI, 1.2-6.9). CONCLUSIONS: The frequency of CRN among SGG infected patients is significantly increased compared with symptomatic age-matched controls, indicating that SGG infection is a strong indicator for underlying occult malignancy.
