1. Bacterial Infections in Hyper IgM Syndrome

Hyper IgM Syndrome is a genetic condition that affects the immune system, leading to difficulty in fighting infections. People with this syndrome produce high levels of a type of antibody called IgM, but not other types like IgG, which help protect against bacterial infections. As a result, they are more susceptible to severe bacterial infections, such as pneumonia or sinusitis. This condition requires careful management, including preventive antibiotics and possibly immunoglobulin therapy, to support the immune system and reduce the risk of infections. Regular medical follow-up is crucial for those affected.
