Unmasking Infection Risks in Multiple Myeloma: Insights from a Retrospective Analysis

Area of Science:

• Hematology
• Oncology
• Infectious Diseases

Background:

• Multiple myeloma (MM) treatments have advanced, but infections remain a significant challenge for patient outcomes.
• Understanding infection risk factors is crucial for improving the quality of care and survival rates in MM patients.

Purpose of the Study:

• To investigate factors that predict infection risk in multiple myeloma patients.
• To analyze the types, timing, and causative organisms of infections in MM patients.

Main Methods:

• Retrospective analysis of medical records from 145 multiple myeloma patients at Kidwai Memorial Institute of Oncology, Bangalore.
• Data collection included patient demographics, disease stage, infection episodes, causative pathogens, and mortality.

Main Results:

• Nearly half (47.5%) of MM patients experienced at least one infection.
• Respiratory infections (76.2%) were most common, often caused by gram-positive bacteria (48.2%).
• Infections were frequently observed at presentation or within the first month, and advanced stages correlated with higher infection risk.

Conclusions:

• Infections are a major cause of morbidity and mortality in multiple myeloma patients.
• Prompt identification and management of infections, particularly respiratory infections caused by gram-positive bacteria, are essential.
• Further research into innovative infection prevention strategies and targeted therapies is needed to improve MM patient outcomes.
