Dilemma in diagnosing incomplete Kawasaki disease in a resource limited setting

Introduction and importance

Kawasaki disease (KD) is an acute febrile systemic vasculitis that predominantly affects small to medium sized vessels and mostly occurs in children below 5 years of age. The morbidity and mortality mostly occur due to cardiac involvement.

Case presentation

The authors present a case of a 5-year-old male child from hilly region of Nepal who presented with fever for 7 days along with strawberry tongue and non-exudative conjunctivitis without rashes, extremity changes or lymphadenopathy. A suspicion of incomplete KD (IKD) was made. The notable investigation findings were increased erythrocyte sedimentation rate, C-reactive protein, leucocyte count and platelets. Echocardiography showed normal findings. Based on the clinical features and supplemental laboratory findings, a diagnosis of IKD was made. The patient improved after intravenous immunoglobulin and Aspirin.

Clinical discussion

The main learning objective that the authors get from this case is the challenges in the diagnosis of IKD in the resource limited setting like Nepal. Whether or not to start intravenous immunoglobulin is a dilemma for the physician in most of the cases of suspected IKD, due to the high cost and poor availability of intravenous immunoglobulin in this setting. Hence, the use of inflammatory markers, supplemental laboratory findings together with the few diagnostic criteria met by the patient helps in making a diagnosis and institute timely treatment with intravenous immunoglobulin and aspirin.

Conclusion

Diagnosis of KD in difficult in resource limited setting.
