What are the 10 common diseases that can cause a secondary immunodeficiency?

Common diseases that can lead to secondary immunodeficiency include HIV/AIDS, Diabetes mellitus, chronic kidney disease, cancer (particularly hematological malignancies), autoimmune diseases (like lupus and rheumatoid Arthritis), malnutrition, chronic liver disease, severe burns, certain viral infections (like hepatitis), and the use of immunosuppressive therapy (for conditions like organ transplants). These conditions can impair the immune system's ability to function effectively, increasing susceptibility to infections and other complications.
