Clinical and Etiological Profile of Acute Undifferentiated Fever With Thrombocytopenia in an Emergency Department.

INTRODUCTION

Acute undifferentiated fever with thrombocytopenia is a common and challenging clinical presentation encountered in the emergency departments of tertiary care centers, particularly in tropical regions, often requiring prompt evaluation and management. The study aimed to explore the clinical and etiological profile of acute undifferentiated fever with thrombocytopenia in the Emergency Department of Indira Gandhi Institute of Medical Sciences, Patna. It investigates factors associated with patient outcomes and compares platelet transfusion requirements among different etiological groups.

METHODS

In this cross-sectional observational study, 350 patients with acute undifferentiated fever with thrombocytopenia were analyzed for one year from October '21 to September '22. Pre-existing chronic infectious diseases, liver cirrhosis, and autoimmune conditions were excluded.

RESULTS

Thrombocytopenia was observed in all patients, with 65% having platelet counts below 50,000/µL. Associations were found between the degree of thrombocytopenia and organ dysfunction, shock, and third space loss. Logistic regression analysis identified thrombocytopenia, organ dysfunction, and platelet transfusion requirement as significant predictors of the overall outcome. Etiological group comparisons revealed higher platelet transfusion requirements in the bacterial group.

CONCLUSION

Prompt recognition and management of thrombocytopenia in acute undifferentiated fever are vital. Thrombocytopenia, along with organ dysfunction and shock, significantly influence patient outcomes. Tailored interventions based on etiological factors are crucial. Further research should focus on specific viral aetiologies in acute undifferentiated fever with thrombocytopenia.
