When Neisseria meningitidis Strikes an Immunocompetent Host and Purpura Fulminans Results

TL;DR

This paper discusses a rare case of purpura fulminans in an elderly immunocompetent woman caused by Neisseria meningitidis infection.

Contribution

The novelty lies in highlighting PF caused by Neisseria meningitidis in an immunocompetent individual.

Findings

PF can occur in immunocompetent individuals due to Neisseria meningitidis.

Early intervention with antibiotics, steroids, and anticoagulants is crucial for survival.

DIC secondary to Neisseria meningitidis can lead to PF.

Abstract

Purpura fulminans (PF) is a rapidly progressive, life-threatening condition marked by ecchymotic, tender, and symmetric skin lesions, often resulting from disseminated intravascular coagulation (DIC) secondary to infectious or non-infectious etiologies. PF usually occurs in immunocompromised hosts and is associated with a high mortality rate. Here, we highlight a case of an elderly immunocompetent woman with Neisseria meningitis-mediated DIC and subsequent PF. Her case underscores the importance of early intervention in managing this rare but deadly condition in order to ensure optimal survival outcomes. Early intervention for PF with DIC includes the timely administration of antibiotics, steroids, and anticoagulants, along with addressing the underlying consumptive coagulopathy.
