RESUMO
BACKGROUND: Ehrlichia chaffeensis is responsible for most cases of human ehrlichiosis, an acute febrile tick-borne disease. This clinical entity is more commonly reported in adults from the United States. Therefore, it is of special interest to characterize this disease in children, given that very few cases in children have been reported outside of this country. CASE REPORT: We describe the case of a 15-year-old female from northeastern Mexico with a five-day history of myalgias, arthralgias, fever, abdominal pain, rash, and somnolence. The possibility of tick-borne disease was suspected considering that she lived with three tick-infested dogs that had recently died and a neighbor with similar symptoms who deteriorated rapidly and died a week earlier. Ehrlichia spp. was detected in blood samples by polymerase chain reaction. The patient completed a seven-day course of doxycycline and was discharged with complete resolution of symptoms. CONCLUSIONS: This case is the first report of ehrlichiosis in a pediatric patient in Mexico, illustrating the importance of considering tick-borne diseases as a differential diagnosis in patients with rash, fever, and altered level of consciousness. This initial clinical presentation may be indistinct from other conditions such as dengue, meningococcemia, and multisystem inflammatory syndrome in children (MIS-C), among others.
INTRODUCCIÓN: Ehrlichia chaffeensis es responsable de la mayoría de los casos de ehrlichiosis humana, una enfermedad febril aguda transmitida por garrapatas. Esta entidad clínica se reporta con mayor frecuencia en adultos de Estados Unidos. Por lo tanto, es de especial interés caracterizarla en niños, dado que se han reportado muy pocos casos en niños fuera de este país. CASO CLÍNICO: Se describe el caso de una paciente de sexo femenino de 15 años, originaria y residente del noreste de México con una historia de cinco días de mialgias, artralgias, fiebre, dolor abdominal, erupción cutánea y somnolencia. Se sospechó la posibilidad de una enfermedad transmitida por garrapatas considerando que convivió con tres perros infestados de garrapatas que habían muerto recientemente y una vecina con síntomas similares, quien se deterioró rápidamente y murió una semana antes. Ehrlichia spp. se detectó en una muestra sérica mediante reacción en cadena de la polimerasa. La paciente completó un curso de siete días de doxiciclina y fue dada de alta con resolución de los síntomas. CONCLUSIONES: Este caso es el primer reporte de ehrlichiosis en un paciente pediátrico en México que ilustra la importancia de considerar enfermedades transmitidas por garrapatas dentro del diagnóstico diferencial de pacientes con exantema, fiebre y alteración del estado de conciencia. Esta presentación clínica inicial puede ser indistinguible de otras entidades como dengue, meningococcemia y síndrome multisistémico inflamatorio, entre otras.

BACKGROUND: Pyelonephritis is one of the most serious bacterial illnesses during childhood. Gram-negative organisms account for up to 90% of the cases. Gram-positive bacteria are uncommon causes of urinary tract infections, and only a few cases caused by Facklamia hominis have been reported in the literature. CASE PRESENTATION: A five-year-old girl with tracheostomy and gastrostomy and past medical history of congenital lymphangioma presented with a two-week history of with intermittent fever, frequent urination, and vesical tenesmus. Diagnosis of pyelonephritis was made. Urine culture reported colonies with alpha-hemolysis in blood agar at 48-h of incubation and Facklamia hominis was identified by MALDI-TOF. The patient was successfully treated with gentamicin. CONCLUSIONS: This is the first reported case of pyelonephritis by Facklamia hominis in a child, and the second involving infection in a pediatric patient. Although this pathogen is uncommon, current treatment of F. hominis is a challenge for physicians. This case illustrates the requirement to standardize identification and treatment of care to avoid treatment failure and antimicrobial resistance.
