ABSTRACT

Background:

Septic arthritis is an infrequent condition of prolonged morbidity and there is no previous publications in Chile that allow orientate therapy.

Aim:

To characterize a group of adult patients with septic arthritis confirmed by culture. Material and

Methods:

Descriptive study of a case series.

Results:

From 2003 to august 2013, 24 patients with 25 events of septic arthritis were identified in a general hospital. Mean age was 68.3 years old (range 24-94). Predisposing conditions were harbored by 91.7%. Predominant clinical manifestations were pain (92%) and impaired joint movement (95.7%). Fever was present in 64%, hypotension in 28% of events, and C-reactive protein > 100 mg/L in 90.6%. Gram positive cocci were the most frequently isolated microorganisms (81.5%), predominating S. aureus (48.1%), and with 4 isolates methicillin resistant isolates (26.7%). Resistant isolates trend to be associated with previous surgery (p = 0.055) and all cases caused by non-fermentative Gram negative bacilli had recent hospitalization or surgery, a feature that did not reach a significant difference. Nine events were associated to bacteremia (36%). Outcome analysis indicated 32% of events with full recovery, 28% with a favorable evolution, 20% with therapy failure and 16.7% patients that died. A total of 24% of the series remained with significant sequels.

Conclusions:

Septic arthritis is an infrequent disease that affects in most cases patients with predisposing conditions. Associated symptoms include pain and impaired joint movement, sometimes fever, hypotension, positive blood cultures and frequently a C-reactive protein > 100 mg/L. Predominant agents are Gram positive cocci, specially S. aureus, including methicillin resistant isolates. Case-fatality ratio, treatment failure and sequels are important.
RESUMEN
Antecedentes Los cuadros de artritis séptica son esporádicos pero de elevada morbilidad y no hay publicaciones en Chile que permitan orientar el tratamiento de ellos.

Objetivos:

Caracterizar un grupo de pacientes con cuadros de artritis séptica confirmados microbiológicamente. Pacientes y

Métodos:

Serie de casos.

Resultados:

Un total de 24 pacientes con 25 eventos de artritis séptica fue identificado entre el 2003 y agosto de 2013. La edad promedio fue de 68,3 años (24-94) y 91,7% tuvo condiciones que predisponen. Las manifestaciones clínicas dominantes fueron dolor (92%) e impotencia funcional (95,7%), 64% presentó fiebre y 28% tuvo hipotensión arterial. Un 90,6% tuvo PCR > 100 mg/L. Las cocáceas grampositivas fueron los microorganismos más frecuentes (81,5%), predominando Staphylococcus aureus (48,1%) y cuatro cepas estafilocóccicas presentaron resistencia a cloxacilina (26,7%). Las cepas resistentes tendieron a estar asociadas a pacientes con cirugía articular previa (p 0,055) y todos los casos asociados a bacilos gramnegativos no fermentadores tenían antecedentes de hospitalización reciente o cirugía articular previa. Nueve eventos (36%) se asociaron a bacteriemia. Un 32% de los pacientes tuvo curación, 28% un curso favorable, 20% fracaso y 16,7% falleció. Un 24% quedó con secuelas.

Conclusiones:

Los cuadros de artritis séptica son infrecuentes, afectan en su mayor parte a pacientes con factores que predisponen, se presentan con dolor e impotencia funcional, a veces fiebre, hipotensión arterial o bacteriemia y generalmente con PCR > 100 mg/L. Se asocian a cocáceas grampositivas, especialmente S. aureus, incluyendo aislados resistentes a cloxacilina. La letalidad, fracaso del tratamiento y secuelas no son despreciables.
