Sepsis Unveils T-cell Large Granular Lymphocytic Leukemia in the Setting of End-Stage Renal Disease: A Rare Hematologic Malignancy.

Large granular lymphocytic (LGL) leukemia is a rare chronic lymphoproliferative disorder originating from natural killer cells or T lymphocytes. In this report, we present the case of a 66-year-old female initially treated for sepsis, with methicillin-sensitive Staphylococcus aureus identified on initial blood culture prompting intravenous (IV) antibiotic therapy. The patient met systemic inflammatory response syndrome criteria upon admission due to severe neutropenia. Persistent fever led to neurological symptoms, and imaging revealed lung abnormalities along with chronic changes on the CT scan of the head. Multidisciplinary consultations were sought, resulting in treatment adjustments including antifungals and filgrastim. Flow cytometry and bone marrow biopsy confirmed the diagnosis of LGL leukemia.

Unmasking the Silent Threat: Cefepime-Induced Thrombocytopenia.

Cefepime, a commonly prescribed fourth-generation cephalosporin, is well-known for its broad-spectrum antibacterial activity. While adverse drug reactions associated with cefepime are well documented, thrombocytopenia as a rare complication has gained attention due to its potential severity. Symptomatic patients present with purpura (bruising), petechiae (small red or purple spots on the skin), and mucosal bleeding. Drug-induced thrombocytopenia can be initiated by myelosuppression by halting platelet formation in the bone marrow or by a drug-induced immune thrombocytopenia reaction. We present a case of a 71-year-old male who experienced thrombocytopenia secondary to cefepime use. We further discussed the underlying mechanisms of cefepime-induced thrombocytopenia, highlighting the need for increased vigilance in monitoring platelet counts during cefepime administration. This case underscores the importance of recognizing and managing this uncommon but potentially life-threatening adverse reaction in clinical practice.
