* In several studies, it has been noticed that there is a strong correlation between the host immune response and lymphoedema development. The immune response is higher in the lymphedema patients more than the patients with microfilariae just cirulating in the blood. | |||
* Hence, it is believed the role of the immune response in development of the lymphedema as it leads to inflammation and obstruction of the lymphatic vessels. | |||
* Infection by filariasis induces cell mediated immunity in response to the filarial antigens. This will lead to production of cytokines and interleukns. | |||
* High levels of immunoglobulins (IgG1,2,3) has been detected in patients with lymphedema which increases the evidence of the role of the immune response in pathogenesis of the disease. | |||

|Secondary bacterial infections | |||

* Adenolymphangitis is a result of the inflammation induced by the filarial infection and the immune response. It is believed that it worsens the disease and leads to morbidity. | |||
* It affects the lower limbs resulting in cord like lesion of the lymphatic vessels and worsening of the filariasis. | |||
