Congenital renal anomalies, Williams Syndrome and non-Hodgkin lymphoma all occur separately at low incidence, so their simultaneous presence in the same patient is exceptional. We present a young patient manifesting all three conditions. This child is a boy with a Williams Syndrome phenotype who was diagnosed with severe chronic kidney disease secondary to bilateral renal dysplasia/hypoplasia. Due to his small size, he received treatment with growth hormone. He progressed to end stage kidney disease and, after 8 months, a renal transplant was performed. A number of suspicious abdominal adenopathies were removed during the surgery and, thereafter, immunosupressive treatment with prednisone, azathioprine and cyclosporine was initiated. Examination of the biopsy tissue confirmed the presence of a T-cell lymphoblastic lymphoma. Appropriate chemotherapy was given, and the immunosupressive regimen was eventually reduced to prednisone alone. Now, 8 years since the initial diagnosis of T-cell lymphoblastic lymphoma and 6 years after the completion of the chemotherapy, the patient is still in complete remission with a functional donor kidney. We discuss some possible explanations of this association. Chemotherapy has not appeared to have affected the viability of the grafted kidney and, in fact, it may even have induced immunotolerance.

The concentration levels of serum lipids and lipoprotein (a) were measured in 20 children receiving carbamazepine, 25 children receiving valproic acid, and 5 children receiving phenobarbital at the following times: (1) during chronic treatment while eating a normal diet, (2) during chronic treatment while eating a low-fat diet (children treated with carbamazepine and phenobarbital with high levels of total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol), and (3) 3 months after the end of treatment with antiepileptic drugs. Patients during chronic treatment and eating a normal diet revealed significant changes in lipids, but when we reevaluated the groups of children treated with carbamazepine and phenobarbital when they were eating a low-fat diet and reevaluated the three groups of children 3 months after the end of treatment, a complete return to normal of all parameters was observed. These data demonstrate that the changes induced by these drugs are transient, reversible, and influenced by a low-fat diet. (J Child Neurol 2006;21:48-53).
