3. Opportunistic Infections in Hyper IgM Syndrome

Hyper IgM Syndrome is a rare immune disorder where the body cannot produce certain antibodies, leading to weak defenses against infections. Individuals with this syndrome are particularly vulnerable to opportunistic infections, which are caused by organisms that usually don't harm healthy people. These include certain bacteria, viruses, and fungi. Because the immune system is unable to respond effectively, even common pathogens can cause serious illness. Early recognition and treatment of these infections are crucial to managing the condition and protecting the patient’s health.
