Multiple etiologies of axonal sensory motor polyneuropathy in a renal transplant recipient: a case report
<p>Abstract</p> <p>Introduction</p> <p>Neurological complications leading to morbidity and mortality are not frequent in renal transplant recipients. Here, we report a renal transplant recipient who presented with diminished strength in his limbs probably due to multiple etiologies of axonal sensorimotor polyneuropathy, which resolved with intravenous immunoglobulin.</p> <p>Case presentation</p> <p>A 49-year-old Iranian male renal transplant recipient with previous history of autosomal dominant polycystic kidney disease presented with diminished strength in his limbs one month after surgery. Our patient was on cyclosporine A, mycophenolate mofetil and prednisone. Although a detected hypophosphatemia was corrected with supplemental phosphate, the loss of strength was still slowly progressive and diffuse muscular atrophy was remarkable in his trunk, upper limb and pelvic girdle. Meanwhile, his cranial nerves were intact. Post-transplant diabetes mellitus was diagnosed and insulin therapy was initiated. In addition, as a high serum cyclosporine level was detected, the dose of cyclosporine was reduced. Our patient was also put on intravenous ganciclovir due to positive serum cytomegalovirus immunoglobulin M antibody. Despite the reduction of oral cyclosporine dose along with medical therapy for the cytomegalovirus infection and diabetes mellitus, his muscular weakness and atrophy did not improve. One week after administration of intravenous immunoglobulin, a significant improvement was noted in his muscular weakness.</p> <p>Conclusion</p> <p>A remarkable response to intravenous immunoglobulin is compatible with an immunological basis for the present condition (post-transplant polyneuropathy). In cases of post-transplant polyneuropathy with a high clinical suspicion of immunological origin, administration of intravenous immunoglobulin may be recommended.</p
Reversible symmetric polyneuropathy with paraplegia after heart transplantation
Background, Neurotoxicity is a well-recognized side effect of
cyclosporine therapy in transplant recipients. Cyclosporine can cause a
wide range of adverse effects on both the central and peripheral nervous
systems.
Methods. We present a case history of symmetric polyneuropathy with
flaccid paraplegia, a rare neurological complication of cyclosporine
administration.
Results. Blood levels of the drug above the therapeutic range
accompanied the neurological manifestations. The syndrome subsided fully
with dose reduction. Patients’ symptoms were attributed to axonal
degeneration of the peripheral nerves, according to electromyography
findings.
Conclusions. Cyclosporine neurotoxicity should always be considered in
patients with neurological complications following transplantation, The
case presented in this article illustrates an additional potential
mechanism of this adverse effect, namely, axonal degeneration of the
peripheral nerves, causing symmetric polyneuropathy
