Treatment: ❑ Only supportive care, ❑Some patients need hospitalization for pain control, kidney biopsy, and/or administration of immunosuppressant agents or, occasionally, IVIG

Treatment: ❑ Patients with DGI should be treated for at least 1 week with IV ceftriaxone. ❑ Treatment duration should be extended in patients who do not improve adequately

Treatment: ❑ Doxycycline is the drug of choice in all nonpregnant patients and children. ❑ Pregnant patients can be treated with chloramphenicol

Vancomycin should be added ❑Rifampin is used as prophylaxis in close contacts of the patients,alternatively single-dose ciprofloxacin and IM ceftriaxone can be administered ❑ Dexamethasone can reduce neurologic sequelae if given early,even before administering antibiotics

Treatment: ❑ The primary treatment of DIC is treatment of the underlying condition ❑ In patients with DIC and bleeding or at high risk of bleeding and a platelet count of <50 x 10(9)/l transfusion of platelets should be considered but non-bleeding patients with DIC, prophylactic platelet transfusion is not given unless there is a high risk of bleeding. ❑Activated partial thromboplastin time (aPTT), administration of fresh frozen plasma (FFP) may be useful in DIC patients with prolonged prothrombin time (PT). ❑In patients where FFP can not be used due to chances of fluid overload,factor concentrates can be used. ❑ Patients with DIC with a primary hyperfibrinolytic state and severe bleeding can be treated with lysine analogues, such as tranexamic acid, 1 g every 8 hourly is administered.
