Abstract
Hepatocellular carcinoma (HCC) is, to date, the most common malignant tumor of the liver and is commonly staged with the Milan criteria. While deceased-donor liver transplantations (DDLT) are reserved for patients within the Milan criteria, living-donor liver transplantation (LDLT) might be a curative option for patients outside the Milan criteria. We here report a case of a 32-year-old woman who developed a giant, unresectable HCC out of a hepatocellular adenoma (HCA) after a pregnancy. The genetically identical twin sister donated her left hemi-liver after ethical approval and preoperative screening. No long-term immunosuppressive therapy was necessary, and after more than eight years, both are in perfect health and the recipient gave birth to a second child. This case shows that in certain situations large HCCs outside the standard criteria can be cured by LT. Careful evaluation of both donor and recipient should be performed for indications like this to assure optimal clinical outcome.

Liver Transplantation from a Human Leukocyte Antigen-Matched Sibling Donor: Effectiveness of Direct-Acting Antiviral Therapy against Hepatitis C Virus Infection. REPORTS 2022.

Abstract
Through living-donor liver transplantation (LDLT) from a human leukocyte antigen (HLA)-matched sibling donor, it may be possible to stop the use of immunosuppressants. It is possible that acute antibody-mediated rejection and chronic active antibody-mediated rejection through the positivity of donor-specific anti-HLA antibodies and/or T cell-mediated rejection may affect the prognosis of liver transplantation. The etiologies of liver diseases of the recipient may also affect the post-transplantation course. Herein, we report on the successful re-treatment with direct-acting antiviral (DAA) therapy against hepatitis C virus (HCV) infection in a patient who underwent a LDLT from HLA-matched sibling donor. After liver transplantation for HCV-related liver diseases, it is easy for HCV to re-infect the graft liver under a lack of immunosuppressants. DAA therapy against HCV re-infection immediately after transplantation should be commenced, and it is important to eradicate HCV for better prognosis of the recipients in LDLT for HCV-related liver diseases.

Abstract
Donor-recipient human leukocyte antigen (HLA) compatibility has not been considered to significantly affect liver transplantation (LT) outcomes; however, its significance in living-donor LT (LDLT), which is mostly performed between blood relatives, remains unclear. This retrospective cohort study included 1954 LDLTs at our institution (1990-2020). The primary and secondary endpoints were recipient survival and the incidence of T cell-mediated rejection (TCMR) after LDLT, respectively, according to the number of HLA mismatches at all five loci: HLA-A, HLA-B, HLA-C, HLA-DR, and HLA-DQ. Subgroup analyses were also performed in between-siblings that characteristically have widely distributed 0-10 HLA mismatches. A total of 1304 cases of primary LDLTs were finally enrolled, including 631 adults (recipient age at LT ≥18 years) and 673 children (<18 years). In adult-to-adult LDLT, the more HLA mismatches at each locus, the significantly worse the recipient survival was (p = 0.03, 0.01, 0.03, 0.001, and <0.001 for HLA-A, HLA-B, HLA-C, HLA-DR, and HLA-DQ, respectively). This trend was more pronounced when multiple loci were combined (all p < 0.001 for A + B + DR, A + B + C, DR + DQ, and A + B + C + DR + DQ). Notably, a total of three or more HLA-B + DR mismatches was an independent risk factor for both TCMR (hazard ratio [HR] 2.66, 95% confidence interval [CI] 1.21-5.87; p = 0.02) and recipient survival (HR 2.44, 95% CI 1.11-5.35; p = 0.03) in between-siblings. By contrast, HLA mismatch did not affect pediatric LDLT outcomes at any locus or in any combinations; however, it should be noted that all donor-recipient relationships are parent-to-child that characteristically possesses one or less HLA mismatch at each locus and maximally five or less mismatches in total. In conclusion, HLA mismatch significantly affects not only TCMR development but also recipient survival in adult LDLT, but not in children.

Abstract
BACKGROUND Twenty-year follow-up of the first reported simultaneous pancreas-kidney transplant from living donor between identical twins. CASE We present a case of a patient after the world's first simultaneous pancreas and kidney transplant between identical twins. The transplant was performed because of diabetes mellitus type (DM1) related renal failure. Now in her sixties, the patient has had exceptional prolonged bi-graft function without immunosuppression. She is free from DM1 recurrence, does not take insulin, and her creatinine level has stayed with the normal limit. CONCLUSIONS Simultaneous pancreas and kidney transplant can be performed successfully with excellent long-term outcomes.

Abstract
There are some reported cases of liver transplant between identical twins with no immunosuppressants because of their matched HLA. However, there is no mention of donor-specific antibodies (DSA). Here, we report a rare case of living donor liver transplant (LDLT) between identical twins, mimicking DSA positivity, on a low-dose immunosuppression protocol. A 57-year-old man with acute liver failure underwent LDLT using the right lobe from his identical twin. Their blood types were identical on HLA matching. However, the preoperative DSA test results were positive for class II antibodies. This was supposed to be due to the relatively large amount of blood transfusion before testing: a total of 580 units of fresh frozen plasma for plasma exchange. The presence of class II antibodies for DSA positivity was the result of the passive immunity from transfusion, and this result could not be ignored, given the risk of rejection. Therefore, we arranged low-dose postoperative immunosuppressants using tacrolimus at a quarter dose and no mycophenolate mofetil. The postoperative course was uneventful. A few months after LDLT, the patient's DSA level was negative for class II antibodies, thus confirming our preoperative hypothesis of DSA as the result of transfusion. Currently, 6 months after LDLT, he is free from immunosuppressive medication with good liver function. When administering relatively large doses of fresh frozen plasma by repeated plasma exchange before LDLT, even between identical twins, it is important to consider that the DSA test could be positive and that immunosuppressive treatment should be performed carefully.

Abstract
We describe the case of a 24-year-old female with end-stage renal disease from focal segmental glomerulosclerosis (FSGS) diagnosed at age 16, who underwent monozygotic triplet transplantation at age 21 from her sister. Monozygosity was established by buccal smear DNA PCR amplification using short tandem repeat (1) profiling for 16 genetic alleles. All immunosuppression was discontinued by 1 month posttransplant. To evaluate the use of immunosuppression in HLA identical monozygotic transplantation, we interrogated the OPTN (Organ Procurement Transplant Network) database for all transplants conducted from 1987 to 2006. We identified 194 probable identical twin transplantations based on age, gender, race, ethnic category, blood type and HLA match. We evaluated the use of various immunosuppressive agents at discharge, 6 months and 1, 2 and 3 years after transplantation. Seventy-one percent of these patients at discharge and 34% at the end of 1 year were on immunosuppression. At discharge 61% received steroids and 30% received calcineurin inhibitors and 66% of these remained on calcineurin inhibitors at 1 year. Renal function was superior among those not maintained on immunosuppression. Thus, monozygotic transplantation confers an immunologic advantage that allows immunosuppression elimination despite a risk of recurrent glomerular disease such as FSGS with appropriate evaluation and management.

Abstract
BACKGROUND Deriving their name from the Greek word plastikos, meaning related to molding, plastic surgeons have made their reputation by transplanting tissues from one area of the body to another to "remold" defects caused by trauma, congenital anomaly, or disease. Dr. Joseph Murray, a plastic surgeon, performed the first successful kidney transplant between identical twins in 1954. The authors present three cases involving the transplantation of perforator flaps from one identical twin to another for breast reconstruction, including cases using both deep inferior epigastric perforator and superficial inferior epigastric artery flaps. METHODS Three sets of recipient monozygotic twins that had breasts treated with mastectomies underwent reconstruction using transplanted tissue from their donor monozygotic twins. All sets of twins underwent DNA testing to determine that they were monozygotic; therefore, no immunosuppressive therapy was indicated. RESULTS The three sets of recipient monozygotic twins underwent successful breast reconstruction using perforator flap transplants from their donor monozygotic twins. The operations included two unilateral reconstructions (one using a deep inferior epigastric perforator flap and the other using a superficial inferior epigastric artery flap) and one bilateral deep inferior epigastric perforator reconstruction. Their hospital courses were unremarkable. CONCLUSIONS Transplant surgery continues to evolve in the twenty-first century. The authors present three cases of breast reconstruction using skin flap transplantation as a new option for breast reconstruction.

Abstract
Using a clinical case, this paper explores the ethical complexities of assessing potential living organ donors when the proposed donor-recipient pair consists of monozygotic (identical) or dizygotic (fraternal) twins. While all donor-recipient pairs can present various ethical and psychosocial challenges, the challenges of twin pairs are unique and especially complex. Donor Advocate Teams need to be aware of these unique issues and address them during their assessment process.

Abstract
Hepatitis C virus reinfection after liver transplantation is universal and more severe than in nontransplant patients. Rejection episodes and immunosuppressive agents are considered risk factors for deterioration of recurrent hepatitis C. We report 2 cases of living donor liver transplantation for patients with hepatitis C-related cirrhosis who received right-lobe grafts from an identical twin. Thanks to genetic identity, no immunosuppressive drugs were administered during or after transplantation without rejection. Hepatitis C virus RNA kinetics showed a rapid increase following transplantation and liver biopsies 1 month after transplantation showed acute lobular hepatitis in both cases. Antiviral therapy using interferon alpha and ribavirin was started immediately, and both cases showed virological and histological response. In conclusion, avoidance of immunosuppression did not delay hepatitis C recurrence following transplantation, while early antiviral therapy without risk of rejection or immunosuppression led to successful viral eradication.

Abstract
Churg-Strauss syndrome (CSS) is a granulomatous small-vessel vasculitis with unknown etiology. Extra-pulmonary manifestations of CSS are currently treated with a combination of steroids and Cyclophosphamide. Its gastrointestinal complications may be devastating, occasionally requiring extensive bowel resection resulting in short-gut syndrome. Living-related small bowel transplantation (LRSBTx) is a relatively standardized procedure that, not only represents a valid alternative to cadaver bowel transplant in selected cases, but also portraits excellent results when performed in experienced centers. The availability of an identical twin as a donor, which allows avoidance of immunosuppressive therapy, is a major indication for this procedure. We present the case of a young individual affected by gastrointestinal necrotizing vasculitis that lost almost his entire small bowel requiring the immediate institution of total parenteral nutrition (TPN). However, within few weeks a significant hepatic dysfunction ensued. An identical twin-brother, not affected with CSS, became an immediate, optimal donor-candidate for LRSBTx, the first of this kind in a patient affected with CSS. Following the procedure, two main concerns were addressed: the recipient's ability to recover a regular intestinal function without immunosuppression and the possible recurrence of the primary disease. Twenty-seven months post-transplant, the patient enjoys a regular lifestyle without any clinical, endoscopic and histologic evidences of recurrent disease in the transplanted graft.

Abstract
BACKGROUND : Due to ongoing organ donor shortage, an increasing number of adult live-donor liver transplants (LDLT) are being performed. The aims of this study were to compare the incidence of ACR between recipients of live- and deceased-donor liver transplants, and to note any differences in ACR among related and unrelated living-donor recipients. METHODS : Sixty-four adults undergoing LDLT between 1998-2001 were closely matched with a deceased recipient. Statistical comparisons in ACR between the live- and deceased-donor groups were based on the differences between the ACR rates of each LDLT patient and the corresponding matched deceased recipient. Analyses were performed separately for pairs in which the living donor was not related to the recipient, was a nonsibling relative, or was a sibling. RESULTS : Live- and deceased-donor recipients underwent a similar number of liver biopsies. In all, 16/50 (32%) of the biopsied LDLT patients had ACR compared to 36/49 (73%) of the deceased-donor recipients. ACR rates of living donors and their deceased-donor matches did not differ significantly for the unrelated living donors, but did differ for the nonsibling related (P=0.03) and the sibling LDLT (P=0.03). The results were similar when comparing rates of high-degree ACR for unrelated, nonsibling related, and sibling pairs. High-degree ACR differences in the sibling LDLT group were significantly greater than in the nonsibling group (P=0.05). CONCLUSIONS : Rates of ACR and high-degree ACR are decreased in living-related liver transplant recipients. This difference is likely genetically related as ACR rates are lower in recipient-donor pairs of increasing genetic similarity.

Abstract
The increasing awareness of liver diseases and their early detection have led to an increase in the number of transplant waiting list candidates over the past decade. This need has not been matched by the actual number of orthotopic liver transplantations performed. Live donor liver transplantation (LDLT) is an innovative surgical technique intended to expand the available organ donor pool. Although LDLT offers definite advantages to the recipient, it offers none to the donor except for the possibility of psychological well-being. Clinical research studies aimed at the prospective collection of data for donors and recipients need to be conducted.

Abstract
A 22-year-old Caucasian patient underwent living-donor liver transplantation (LDLT) for hepatic hemangioendothelioma in a healthy liver. The organ donor was his monozygotic twin brother. Surgery was uneventful in both donor and recipient, who received the same postoperative treatment (i.e. no immunosuppression for the recipient). Although both donor and recipient achieved a full liver function recovery, the volume of the recipient's graft increased much more than the donor's residual liver in the first postoperative month (1.6-fold vs. 1.2-fold). This different growth rate correlated with growth hormone (GH)/insulin growth factor (IGF) axis dynamics: the donor had significantly lower insulin-like growth factor 1 (IGF-1), insulin-like growth factor 2 (IGF-2) and insulin-like growth factor binding protein 3 (IGFBP-3) values than the recipient on postoperative days (POD) 3-30, although they had similar GH values. Other potential regenerative factors, e.g. tumor necrosis alpha, interleukin 6 (IL-6), insulin and C peptide did not correlate with liver regeneration rate. The particular endocrine picture of the graft may be explained by a modified GH-hepatocyte interaction due to cold ischemia during preservation resulting in a higher IGF production. Whether this is a potential molecular tool by means of which transplanted partial livers promote their regeneration remains to be seen in a larger number of patients.
