Unusual presentation of rheumatic fever in a 3-year-old child in the UK

In the developed world, acute rheumatic fever (ARF) is rare. When it does arise, symptoms commonly include fever, arthralgia and rash. We describe a presentation of a 3-year-old child with ARF in a UK District General Hospital. The patient had a 6-week history of diarrhoea, rash and intermittent right hip arthralgia. This was initially thought to be a viral illness until she re-presented with shortness of breath and fever with a pan-systolic murmur. A throat-culture was negative, but an anti-streptolysin titre was elevated, with a bedside echocardiogram demonstrating moderate to severe mitral regurgitation. The young child was transferred to the local tertiary centre for further management; however, she went on to develop acute left ventricular failure. This case illustrates the need to be vigilant for the presentation of a rare illness, such as rheumatic fever, as there can be significant impacts on the quality of life of young patients.
