Carimune: A Comprehensive Guide to Its Benefits, Dosages, and Precautions

Carimune, also known by its generic name, immune globulin IGIV, is a medication typically prescribed to strengthen the immune system in patients who are at higher risk of certain infections. 

Carimune belongs to the “immune globulins” drug class, and it is made up of highly purified and concentrated forms of IgG antibodies (96% of IgGs). This medication contains IgG immunoglobulins prepared from the pooled plasma of thousands of healthy donors. 

Carimune is available in sterile, lyophilized powder form that is reconstituted before infusion. Currently, this medication is being sold under various common brand names such as Bivigam, Flebogamma, Gammagard को परिचय S/D, Gammaplex, Octagam को परिचय, Panzyga, Privigen को परिचय, Vigam, Vivaglobulin, and Carimune NP. 

What Is Carimune Used to Treat?

In addition to strengthening the patient’s immune system, Carimune can  also be prescribed for the following conditions:

• Primary immunodeficiencies (PID) 
• B-cell chronic lymphocytic leukemia
• Acute or chronic idiopathic thrombocytopenia purpura (ITP)
• Kawasaki syndrome
• बहु-फोकल मोटर न्यूरोपैथी
• डर्मेटोमायोसाइटिस
• क्रोनिक इन्फ्लेमेटरी डिमाइलिनेटिंग पोलिन्यूरोपैथी (CIDP)

IGIV may also be used off-label for other purposes not listed in this medication guide.

यस्ले कसरी काम गर्छ?

Since Carimune contains 96% of all IgG antibodies, it exerts a wide range of effects in patients with different conditions, which are as follows:

It Boosts the Immune System

Patients with primary immunodeficiency disorders such as X-linked agammaglobulinemia, common variable immunodeficiency, and severe combined immunodeficiency are more prone to various infections. 

Carimune works to boost the immune system by supplying the missing or deficient antibodies, ultimately reducing the frequency and severity of infection in these patients. 

It Increases Blood Clotting Cells (Platelets)

Patients with acute or chronic idiopathic thrombocytopenia purpura experience low levels of blood-clotting cells called platelets due to the attack of autoantibodies (abnormal antibodies produced by the immune system against healthy cells such as platelets).  

Carimune works to increase the level of platelets by neutralizing the effects of autoantibodies. 

It Modulates Hyperactive Immune Responses

Similarly, Carimune also neutralizes or blocks the action of autoantibodies in patients with CIDP or multifocal neuropathy (a disorder in which the immune system attacks the nerves).

It Prevents Infection and Aneurysm

In patients with B-cell chronic lymphocytic leukemia, Carimune helps to prevent certain infections. It also prevents aneurysms (which occur as a result of weakness in the main artery of the heart) in patients with Kawasaki disease.

Dosage for ITP

For the treatment of ITP, a dose of 0.4g/kg of body weight should be administered in patients for 2 – 5 consecutive days.
