Drug of choice in Neonatal ITP is –
**Question:** Drug of choice in Neonatal ITP is –
A. Prednisolone
B. Cyclosporine
C. Etanercept
D. Intravenous Immunoglobulin (IVIG)
**Core Concept:**
Neonatal Immune Thrombocytopenic Purpura (NITP) is a condition characterized by a decrease in platelets (thrombocytes) in a neonate, resulting in bleeding manifestations. This autoimmune disorder is caused by the destruction of platelets by the host's immune system, leading to thrombocytopenia.
**Why the Correct Answer is Right:**
Drug selection for neonatal ITP depends on the severity of thrombocytopenia and the gestational age of the infant. In this case, Intravenous Immunoglobulin (IVIG) is the correct choice as it is a polyclonal preparation of IgG antibodies that can suppress the immune response and prevent platelet destruction.
**Why Each Wrong Option is Incorrect:**
A. Prednisolone is an immunosuppressive drug, but its use in neonates is limited due to long-term side effects, such as growth retardation, Cushing's syndrome, and adrenal suppression.
B. Cyclosporine is an immunosuppressive drug used in organ transplantation but is not a first-line choice for neonatal ITP. Its use in neonates is associated with nephrotoxicity and hypertension.
C. Etanercept is a TNF-alpha inhibitor used in autoimmune diseases but is not suitable for neonatal ITP. It is associated with increased susceptibility to infections and exacerbation of preexisting infections.
**Clinical Pearl:**
In neonates with mild thrombocytopenia, observation and supportive care are often sufficient. However, when treatment is required, IVIG is the preferred choice due to its safer profile compared to other immunosuppressive agents.
