The workup resulted in a analysis of AIDP and administration of intravenous immunoglobulins plus steroids was initiated. or adult unrelated donor. Autoimmune diseases happening after allogeneic hematopoietic cell transplantation (HCT) are mostly antibody mediated and organ specific [1,2]. Neurologic complications after allogeneic HCT happen in 1442% Vibunazole of individuals [3,4] Mouse monoclonal to TGF beta1 and can include seizures, encephalopathy, infections, and polyneuropathy. Immune mediated demyelinating disease after HCT is definitely a rare entity with unclear etiology that can be a manifestation of graft-versus-host disease [5]. A thorough workup is constantly warranted to rule out infectious etiologies when individuals present with neurologic manifestations after allogeneic HCT and in particular cord blood transplantation. == 2. Case Demonstration == A 55-year-old male with relapsed refractory CLL received two times cord blood transplant (DUCBT) with two 5/6 HLA matched cord blood devices (antigen levels HLA-A, HLA-B and allele level HLA-DRB1). Conditioning was a reduced intensity regimen consisting of fludarabine, Cytoxan, and total body irradiation. The treatment for prevention of graft-versus-host disease (GVHD) was with cyclosporine and mycophenolate. On day time 13 after DUCBT, he developed top and lower respiratory tract illness with respiratory syncytial disease (RSV) requiring inhaled ribavirin therapy. Patient achieved a successful neutrophil engraftment by day time 27 after DUCBT. Early posttransplant program was complicated by grade 4 acute GVHD of the gut having a total resolution with steroid therapy and successful taper of all immunosuppression by day time 180 after DUCBT. On day time 221 after transplantation, patient presented with pores and skin rash and tingling in both ft that progressed rapidly to lower extremity paralysis over the course of 2 days. Physical exam showed maculopapular rash influencing his top extremities, top chest, and back area accounting for almost 50% of his body surface area. Neurologic examination was significant for symmetric engine weakness in lower extremities 2/5, plantar flexion, and knee flexion 3/5. He had loss of deep tendon reflexes in both lower extremities (Achilles and Patellar) and top extremities (biceps and triceps). Laboratory workup revealed normal blood counts, organ function (kidney and liver), vitamin B12, Vibunazole folate, thyroid function (TSH level), and free cortisol. Serum electrophoresis and immunofixation were also normal. Magnetic resonance imaging of the central nervous system showed slight neural foramina narrowing in the L4-L5 level. Serologies for Lyme disease, Epstein Pub disease (EBV), syphilis, Cytomegalovirus (CMV), Hepatitis profile, HIV, toxoplasma, enterovirus, and human being herpes virus 6 were all bad. Blood checks for autoimmune markers including (anti-nuclear antibody) ANA, acetylcholine esterase, and volted calcium channel antibodies were normal. A lumbar puncture was Vibunazole performed and showed a high protein level of 67 mg/dL, 1 nucleated cell/mm3, and a normal glucose level. Cerebrospinal fluid was bad for oligoclonal bands, West Nile disease, cryptosporidium, HHV6, herpes viruses 1 and 2, gram stain, and ethnicities. Nerve conduction studies and Vibunazole needle electromyography were suggestive of acute demyelinating polyneuropathy. A pores and skin biopsy was consistent with GVHD. Based on the above workup, he was diagnosed with AIDP and started on therapy with intravenous immunoglobulins at 0.5 gm/kg for 4 days and prednisone 1 mg/kg daily for the treatment of GVHD. Etiology of AIDP was presumed to be related to GVHD as his workup was bad for campylobacter, HIV and CMV, and additional infectious etiologies. He improved significantly over the next 4 weeks and became ambulatory without assistance but his weakness symptoms relapsed as his prednisone dose was being tapered. Prednisone was improved again to 1 1 mg/kg and sirolimus.
