    Successful Treatment With Third Stem Cell Transplant From an Allogeneic Donor for a Patient With Relapsed Diffuse Large B-Cell Lymphoma
    (Başkent Üniversitesi, 2013-04) Takasaki, Hirotaka; Tomita, Naoto; Motomura, Shigeki; Sakai, Rika; Ishigatsubo, Yoshiaki; Tsuchihashi, Hitoshi; Yamamoto, Wataru; Ishii, Yoshimi
    High-dose chemotherapy with autologous stem cell transplant is commonly used for diffuse large B-cell lymphoma that recurs after successful salvage chemotherapy. However, in patients in whom the disease recurs again, the prognosis is poor. A 40-year-old woman who underwent allogeneic stem cell transplant 4 years after autologous stem cell transplant developed recurrent diffuse large B-cell lymphoma 3 years after the initial autologous stem cell transplant. She then underwent reduced-intensity hematopoietic stem cell transplant from a human leukocyte antigen-matched, unrelated donor who was not the previous autologous stem cell transplant donor. She achieved a long survival (328 days after the reduced-intensity hematopoietic stem cell transplant and 1844 days after the first allogeneic transplant). A second allogenic transplant may provide survival benefits in a proportion of patients with malignant lymphoma recurring after allogeneic transplant, although careful consideration is required because of the high risk of treatment-related mortality with second allogenic transplant.

    Total Laparoscopic Donor Nephrectomy In Situs Inversus Totalis: A Case Report
    (Başkent Üniversitesi, 2013-04) Berber, Ibrahim; Gurkan, Alihan; Cakir, Ulkem; Alim, Altan; Gurluler, Ercument; Gures, Nazim
    Situs inversus totalis is a rare anomaly characterized by the total inversion of all abdominal and thoracic organs. For the first time, we report a case of a donor nephrectomy in a patient with situs inversus totalis, completed with a full laparoscopic approach. At the time of this writing, the donor and the recipient are doing well after 6 month’s follow-up. Our experience shows that patients with situs inversus totalis may be eligible candidates for laparoscopic donor nephrectomy, provided that detailed preoperative imaging studies as well as precise preoperative planning are performed before the transplant.

    Plasma Cell-Rich Acute Rejection With Monoclonal Gammopathy in a Renal Transplant Recipient
    (Başkent Üniversitesi, 2013-04) Sun, In O; Yang, Chul Woo; Choi, Yeong Jin; Kim, Yong Soo; Park, Cheol Whee; Park, Gyeong Sin; Choi, Bum Soon; Chung, Byung Ha; Hong, Yu Ah; Cho, Yul Hee
    Plasma cell infiltration into a renal allograft comprises a spectrum of lesions from acute rejection to posttransplant lymphoproliferative disease. We report an unusual case of plasma cell infiltration into a renal allograft with monoclonal gammopathy. A 42-year-old woman was admitted because of graft dysfunction after noncompliance with immunosuppressive therapy for 5 months. A graft biopsy showed acute T-cell–mediated rejection and massive plasma cell infiltration. Despite initial treatment with steroids and antithymocyte globulin, there was persistence of graft dysfunction, monoclonal gammopathy, and plasma cell infiltration. Subsequent treatment with bortezomib improved graft function and caused the monoclonal gammopathy to resolve. Immunohistochemical evaluation of markers of B cells (CD20 and CD138) and the ratio of kappa-to-lambda light chain (15:1) showed that infiltrating cells were plasma cells producing kappa light chain. This suggested that plasma cell-rich acute rejection with monoclonal gammopathy in this patient might have been in an early stage of kappa light chain-producing posttransplant lymphoproliferative disease confined to the renal allograft, and that bortezomib may be effective in treating a patient with this condition.

    Torsion of Extraperitoneally Transplanted Kidney: An Unusual Complication
    (Başkent Üniversitesi, 2013-04) Ozmen, Mehmet Mahir; Koc, Mahmut; Ziraman, Ipek; Bilgic, Ismail
    Torsion of the extraperitoneally transplanted kidney is rare complication with no clinical data in the literature. The authors present the case of a 44-year-old man with end-stage renal disease who received a kidney transplant from his father. On postoperative day 4, serum urea and creatinine levels increased and urine output decreased. Renal ultrasonography revealed the renal hilum to be rotated to the lateral pelvic border, causing mild pelvocaliectasis, and Doppler ultrasonography, the patients showed a poststenotic flow pattern. After the patient underwent urgent reoperation, all laboratory values and ultrasonography findings returned to normal. To the authors’ knowledge, this is the first published case report of torsion of the extraperitoneally transplanted kidney. When posttransplant deterioration in renal function occurs, renal torsion should be considered in the differential diagnosis.

    Liver Transplant From an ABO-Incompatible and Hepatitis C Antibody-Positive but an HCV-RNA Negative Living Donor in a Familial Amyloid Polyneuropathy Patient
    (Başkent Üniversitesi, 2013-04) Takeichi, Takayuki; Ohya, Yuki; Inomata, Yukihiro; Lee, Kwang-Jong; Okumura, Kenji; Yamamoto, Hidekazu; Asonuma, Katsuhiro
    Familial amyloid polyneuropathy is a rare, progressively disabling, and ultimately fatal inherited disease. Liver transplant is currently the only available treatment proven to halt the progression of familial amyloid polyneuropathy. We report a 31-year-old woman with familial amyloid polyneuropathy who received a living-donor liver transplant from her husband who was hepatitis C virus antibody-positive but HCV-RNA negative and ABO incompatible. Six years after the transplant, both donor and recipient have normal liver biochemistry results; no hepatitis C viral load has been detectable in the recipient. This is the first report of a living ABO-incompatible liver transplant from an anti-hepatitis C virus antibody-positive but an HCV-RNA negative donor. This experience suggests that the use of an anti-hepatitis C virus antibody-positive hepatic graft is possible in select circumstances.

    De Novo Postallogeneic Hematopoietic Stem Cell Transplant Membranous Nephropathy
    (Başkent Üniversitesi, 2013-02) Numata, Akihiko; Muto, Shigeaki; Ando, Yasuhiro; Kusano, Eiji; Yumura, Wako; Takemoto, Fumi; Saito, Osamu; Mori, Masaki; Morishita, Yoshiyuki
    We report membranous nephropathy in a 61-year-old man after allogeneic hematopoietic stem cell transplant without chronic graft-versus-host disease. A diagnosis of acute myeloid leukemia was made, and the patient received hematopoietic stem cell transplants, twice, from different donors. The first donor was his brother and the second donor was an unrelated man. Human leukocyte antigens between donors and recipient were fully matched. His clinical course was stable without acute or chronic graft-versus-host disease or relapse of acute myeloid leukemia with tacrolimus after the second hematopoietic stem cell transplant. Six months after the second hematopoietic stem cell transplant, tacrolimus was decreased gradually and discontinued because of tacrolimus-induced liver dysfunction. Three months after discontinuing the tacrolimus, the patient developed edema in his leg. The results of a blood analysis showed that plasma albumin level was 21 g/L and plasma total cholesterol level was 11.5 mmol/L, while results from a urinalysis showed proteinuria of 5.6 g/d without hematuria. No abnormalities in the skin, mucosal tissues, and other organs suggestive of chronic graft-versus-host disease were seen. A renal biopsy was done to investigate the cause, which revealed renal disease. Electron microscopic analysis showed dense deposits in the subepithelial region in all glomeruli. Immunofluorescence analysis showed the deposition of IgG4 and C3c in the subepithelial space of all glomeruli. Membranous nephropathy was diagnosed. He then was administered prednisolone at a dosage of 45 mg/d (0.7 mg/kg/d). After prednisolone treatment, urine protein and hypoalbuminemia were markedly improved, and his leg edema disappeared. These results suggest that this membranous nephropathy may have been de novo membranous nephropathy after hematopoietic stem cell transplant because it developed after hematopoietic stem cell transplants without chronic graft-versus-host disease.

    Diabetic Ketoacidosis Associated With Acute Pancreatitis in a Heart Transplant Recipient Treated With Tacrolimus
    (Başkent Üniversitesi, 2013-02) Im, Moon-Sun; Lee, Hae-Young; Kim, Ki-Bong; Cho, Hyun-Jai; Ahn, Hyo-Suk
    New-onset diabetes mellitus after transplant is a well-recognized complication of tacrolimus immunosuppression and commonly occurs as a form of type 2 diabetes mellitus. However, tacrolimus-associated acute pancreatitis causing diabetic ketoacidosis has not been reported in heart transplant patients. We report a 22-year-old women hospitalized owing to diabetic ketoacidosis associated with acute pancreatitis 7 months after a heart transplant. Her immunosuppression included tacrolimus. She was admitted with complaints of polydipsia, anorexia, and abdominal pain of 3 days’ duration. Her initial laboratory test revealed a toxic level of tacrolimus (> 30 ng/mL), severe hyperglycemia (39 mmol/L), severe metabolic acidosis (pH 6.9), and ketonuria, although diabetes mellitus had never been diagnosed. Serum amylase and lipase levels and abdominal computed tomography suggested the presence of acute pancreatitis. After correcting the diabetic ketoacidosis and getting the tacrolimus level to the normal range, she was discharged home. Three months later, insulin was replaced with oral hypoglycemic agents. Pancreatitis can present with diabetic ketoacidosis in the recipient of a heart transplant treated with tacrolimus. Clinicians should pay more attention to tacrolimus levels and the risk of pancreatitis.

    Treatment of Liver Transplant Graft-Versus-Host Disease With Antibodies Against Tumor Necrosis Factor-α
    (Başkent Üniversitesi, 2013-02) Blank, Gregor; Königsrainer, Alfred; Nadalin, Silvio; Handgretinger, Rupert; Kratt, Thomas; Li, Jun
    Acute graft-versus-host disease is uncommon after liver transplant. We recently treated a 60-year-old man with liver transplant for hepatocellular carcinoma. After the primary liver transplant graft did not function, revision liver transplant resulted in excellent function. Subsequently, the patient developed watery diarrhea, systemic inflammatory response syndrome, a skin rash on his limbs and trunk, and palmar erythema. Skin biopsy suggested viral exanthems consistent with cytomegalovirus. Despite treatment for cytomegalovirus, intestinal symptoms worsened. Analysis of peripheral blood with fluorescence-activated cell sorting showed a high proportion of T lymphocytes, with 5% to 10% T cells specific to the second donor, suggestive of graft-versus-host disease. Within 48 hours after beginning therapy with antibodies against tumor necrosis factor-α (infliximab), the skin rash disappeared and endoscopy showed slight improvement of the mucosal regeneration. However, despite antifungal prophylaxis with caspofungin, the patient developed angioinvasive pulmonary aspergillosis and multiple organ failure, and he died. In conclusion, typical clinical symptoms of graft-versus-host disease after liver transplant may include skin rash and gastrointestinal symptoms, and diagnosis may be confirmed by histologic examination and testing for blood chimerism. A consensus for the treatment of graft-versus-host disease still is lacking, but tumor necrosis factor-α is an encouraging target for therapy to decrease the symptoms of graft-versus-host disease and enable mucosal regeneration.

    Treatment of Pure Red-Cell Aplasia With Cyclosporine in a Renal Transplant Patient
    (Başkent Üniversitesi, 2013-02) Yildirim, Rahsan; Aydinli, Bulent; Gokbulut, Puren; Uyanik, Abdullah; Keles, Mustafa; Bilen, Yusuf
    Acquired pure red-cell aplasia is a rare disorder that can be either idiopathic or associated with certain autoimmune diseases, pregnancy, lympho­proliferative disorders, nutritional deficiencies, or medicines. We present a deceased-donor renal transplant patient who developed pure red-cell aplasia associated with mycophenolate mofetil or tacrolimus and was treated with cyclosporine. A 20-year-old woman was transplanted from a deceased donor 1 month earlier and presented to us with symptoms of fatigue, prostration, and palpitation. The results of a laboratory examination revealed anemia. A diagnostic work-up resulted in a diagnosis of pure red-cell aplasia. Mycophenolate mofetil was discontinued. Tacrolimus also was replaced with cyclosporine 2 months after mycophenolate mofetil was halted because of a lack of improvement in anemia. Three months later, her anemia improved with cyclosporine. Starting cyclosporine instead of tacrolimus or mycophenolate mofetil showed good improvement in our patient within 6 months of therapy.

    Relapsing Mycobacterium Genavense Infection as a Cause of Late Death in a Lung Transplant Recipient: Case Report and Review of the Literature
    (Başkent Üniversitesi, 2012-12) Lhuillier, Elodie; Dauriat, Gaëlle; Ruimy, Raymond; Mal, Hervé; Mourvilliers, Bruno; Danel, Claire; Veziris, Nicolas; Brugière, Olivier
    Mycobacterium genavense is recognized as a life-threatening pathogen in severely immuno­compromised patients, mostly in those with advanced human immunodeficiency virus infection. We report a case of M. genavense infection in a lung-transplant recipient with late-onset death occurring from disseminated infection. In human immunodeficiency virus-negative patients, there exist only about 10 reports of disseminated M. genavense infection in immunocompromised hosts; and to our knowledge, this is a first reported case of M. genavense infection after a lung transplant. Diagnosis of M. genavense was obtained only with nucleic acid-based identification technique, as frequently observed in a few cases of human immunodeficiency virus-negative patients. A striking feature was the recurrence of this infection in our patient after a seemingly infection-free period of 3 years. Because M. genavense infection can be life-threatening, clinicians must be aware of the frequent requirement for nucleic-acid–based identification for its diagnosis.
