RESUMO

Resumen Streptococcus equi subespecie zooepidemicus es una cocácea grampositiva, p-hemolítica, considerada parte de la microbiota de los equinos y un patógeno oportunista en otros animales. La infección en humanos es poco frecuente, pero suele manifestarse como cuadros graves. Se ha asociado al contacto con animales, especialmente caballos, y al consumo de productos lácteos no pasteurizados. Presentamos el caso de una bacteriemia en un binomio madre-hijo por este agente, asociado al consumo de quesos artesanales. Pese a que la penicilina es el tratamiento de elección, la recién nacida fue tratada en forma exitosa con ampicilina y la madre con ceftriaxona. Ninguna de ellas presentó complicaciones asociadas a la bacteriemia. A nuestro conocimiento, este es el primer reporte de infección connatal por este agente.


Abstract 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.

RESUMO

Se revisa críticamente la información científica relacionada con deficiencia de vitamina D (DVD) y riesgo de infecciones respiratorias agudas bajas (IRAB) o asma bronquial en niños. Las IRAB, en especial por virus respiratorio sincicial (VRS) están asociadas a una alta carga de enfermedad. Al no contar aún con una vacuna para ellas, las medidas preventivas y de sostén son las más importantes. El DVD es prevalente en todos los ambientes geográficos, con consecuencias ligadas al metabolismo de calcio y óseo, pero también alteraciones de la inmunidad. Hay evidencia inicial de una asociación entre DVD y mayor riesgo de IRAB, especialmente durante los primeros meses de vida; alelos de algunos polimorfismos del receptor de vitamina D podrían asociarse a un mayor riesgo de IRAB. Este escenario cosmopolita, justifica estudiar el impacto de medidas de suplementación de VD adaptadas a las realidades locales, a la madre durante el embarazo y/o al niño en los primeros meses de vida, que impacten sobre el riesgo de presentar IRAB y asma.


We critically review the information about vitamin D deficiency (VDD) and risk of lower respiratory infections and asthma in children. Acute lower respiratory infections (ALRI), particularly those due to respiratory syncytial virus (RSV) are associated with a high burden of disease. In theabsence of a vaccine for them, prevention and support during illness are important measures to reduce the risk of acquiring the condition or decreasing its severity. VDD has been described as prevalent in all geographical environments; its consequences are linked to calcium and bone metabolism, but also to impaired immunity. Recent evidence of an association between VDD and increased risk of ALRI, especially during the first few months of life has been demonstrated; alleles of some polymorphism of vitamin D receptor may be involved in an increased risk of LRTI. It is justified to study the impact of measures of vitamin D supplementation adapted to local environments, including the appropriate doses to the mother during pregnancy and/or to the child in the first months of life, on the risk of ALRI, or asthma in later ages.
