ABSTRACT

Caso clínico: Paciente de sexo masculino, de 69 años, sin otros antecedentes. Debuta con dolor en zona de la cadera derecha transitorio, evolucionando con cuadro de seis días de desarrollo de fiebre hasta 39,2ºC, calofríos, artralgias en tarso derecho, rodillas, hombros y astenia, por lo que fue hospitalizado. Al examen destacaba aumento de volumen doloroso en rodilla izquierda y hombro derecho. El estudio de líquido articular descartó artritis infecciosa y presencia de cristales intraarticulares. Los exámenes séricos mostraban parámetros inflamatorios alterados con leucocitosis, VHS y PCR elevados. Panel viral negativo. Sin otro foco inflamatorio evidente, se inició manejo antibiótico empírico con Ceftriaxona y Cloxacilina, con buena respuesta, mejorando su sintomatología y parámetros inflamatorios. Cultivos articulares negativos. El Gram de hemocultivos demostró la presencia de bacilos Gram negativos, aislando en los hemocultivos Streptobacillus moniliformis. El paciente evoluciona favorablemente, con regresión total de su cuadro articular. Discusión y conclusión: La Fiebre por Mordedura de Rata es una enfermedad sistémica que típicamente se presenta con fiebre, rash cutáneo y poliartralgias migratorias. Uno de sus principales agentes causales es el Streptobacillus moniliformis, que coloniza la nasofaringe de ratas y otros roedores. Casos aislados han sido reportados en Chile. En la Fiebre por Mordedura de Rata hasta un 50 por ciento de los pacientes desarrolla artritis con derrame articular o sin él. Puede afectar cualquier articulación, pero la más comúnmente comprometida es la rodilla. El dolor articular disminuye en las primeras tres semanas del uso de antibióticos, pero la articulación en ocasiones puede llegar a ser destruida. En sujetos sanos se han reportado tasas de mortalidad de 10 por ciento a 15 por ciento. Mientras todos los síntomas se resuelven puede haber recaídas con graves complicaciones, como meningitis, endocarditis...


Clinical case: Male patient, 69 years old and no previous record. First episode with transitory pain in the right hip zone, going on to 6 days of fever that evolves to 39.2 ºC, shivers, articular pain in the right tarsus, knees, shoulders and asthenia, so he was hospitalized. Upon examination, painful swellings of the left knee and right shoulder stood out. A study of synovial fluid ruled out infectious arthritis and presence of intra-articular crystals. Blood tests showed altered inflammatory parameters with high leukocytes, VHS and CRP. Negative viral panel. Without another evident inflammatory focus, an empirical management was initiated by means of antibiotics with Ceftriaxone y Cloxaciline, which had a good response relieving symptoms and inflammatory panels. Negative articular culturing. The blood culture Gram showed presence of negative Gram bacilli, with the isolation of Streptobacillus moniliformis in the blood cultures. Patient evolves favorably, with full regression of his articular symptoms. Discussion and conclusion: Rat-bite fever is a systemic sickness that typically presents itself with high fever, skin rash and migratory poly-articular pain. One of its main causing agents is the Streptobacillus moniliformis that colonize the nasopharynx of rats and other rodents. Isolated cases have been reported in Chile. In Rat-bite Fever up to 50 percent of patients develop arthritis with and without joint effusion. It may affect any joint, but that most commonly compromised is the knee. Articular pain subsides in the first 3 weeks of use of antibiotics, but the joint may sometimes even be destroyed. Mortality rates in healthy individuals have been reported at 10 percent to 15 percent. While all symptoms disappear there might be relapses with serious complications such as meningitis, endocarditis, myocarditis, pneumonia and fulminant sepsis that may cause the patient to die. Timely diagnose and treatment are paramount to avoid its serious...

ABSTRACT

We report a case of bacteremia caused by Streptobacillus moniliformis. A 2 years and 3 months female Kuwaiti child presented with febrile convulsions, mild cough and vomiting. The patient's history, clinical findings and radiological investigations were reviewed. There was no history of rat/animal bite, but the child had been camping in the desert prior to the illness and may have been exposed to rodent excreta. On two occasions, blood culture specimens yielded pure growth of the organism which was identified by standard diagnostic criteria. The patient was successfully treated with cefotaxime and clarithromicin. S. moniliformis may be a cause of bacteremia even in the absence of rat/animal bites

ABSTRACT

Rat bite fever is a rare, systemic illness caused by Streptobacillus moniliformis or Spirillum minus following a rat or other rodent bite. Characteristically, fever develops abruptly with maculopapular skin rash after an incubation period of two to ten days, and asymmetric migrating polyarthritis starts later in up to 50% of patients. The arthritis involves the knees, shoulders, elbows, wrists and hands, which may either be suppurative or non-suppurative. Although most cases seem to resolve spontaneously within two weeks, the mortality in untreated cases is around 10~15%. The response to antibiotic treatment is good and early diagnosis is the most important prognostic factor. We report a patient who developed arthritis with fever after biting by rat.

ABSTRACT

Numerosas afecciones son transmitidas al hombre por diferentes vectores, sean éstos insectos, pájaros o mamíferos. Entre las transmitidas por estos últimos, en la presente revisión se abordaron: la enfermedad por mordedura de rata que es básicamente un cuadro febril agudo, intenso, de comienzo brusco y de evolución recurrente y la enfermedad por rasguño de gato que se manifiesta por adenopatías sin signos inflamatorios locales, de lenta evolución regresiva y con escasa repercusión sobre el estado general. Ambas afecciones son más comunes en nuestro medio de lo que habitualmente se piensa y responden favorablemente a diversos antibióticos pero inicialmente plantean, con frecuencia, problemas de diagnóstico diferencial con enfermedades de pronóstico más grave
