Long term complication (> 10 yr) renal transplantation is/are -a) Bacterial infectionb) Malignancyc) Viral infectiond) Acute graft versus host reactione) Psychosis
## **Core Concept**
Long-term complications of renal transplantation refer to the adverse effects that occur beyond the 10-year mark post-transplantation. These complications arise due to prolonged immunosuppression, chronic rejection, and other factors related to the transplanted kidney and the recipient's health.
## **Why the Correct Answer is Right**
The correct answer involves identifying complications that are known to occur in the long term after renal transplantation. **Malignancy (b)** is a well-recognized long-term complication due to chronic immunosuppression, which increases the risk of various cancers, particularly skin cancers and lymphomas. **Viral infection (c)** can also be a long-term issue, as immunosuppressed patients are more susceptible to viral infections, including cytomegalovirus (CMV) and Epstein-Barr virus (EBV) reactivations.
## **Why Each Wrong Option is Incorrect**
- **Option A: Bacterial infection** - While bacterial infections can occur at any time post-transplant, they are more commonly considered short-term complications, especially in the first year. However, they can still occur long-term but are not as specifically highlighted as long-term complications compared to malignancy and viral infections.
- **Option D: Acute graft versus host reaction** - This is incorrect because graft-versus-host disease (GVHD) is typically an acute complication of bone marrow transplantation rather than renal transplantation. Chronic GVHD can occur but is less common and not specifically listed as a long-term renal transplant complication.
- **Option E: Psychosis** - While psychosis can be a complication of various medical conditions and treatments, it is not specifically listed as a common long-term complication of renal transplantation.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that long-term survivors of renal transplants are at increased risk of **malignancies**, particularly skin cancers, lymphomas, and Kaposi's sarcoma, due to chronic immunosuppression. Regular screening and preventive measures are crucial.
## **Correct Answer:** B.
