Graft-versus-host disease (GVHD) after liver transplantation (LT) is a rare complication with high mortality and is clinically characterized by fever, skin rash, and diarrhea. The clinical manifestations of GVHD after LT are nonspecific and may resemble viral infection or adverse drug reaction, posing a diagnostic and therapeutic challenge. We report a 60-year-old male who presented with generalized erythematous to violaceous macules and papules accompanied by fever and diarrhea after orthotopic LT. A skin biopsy and human leukocyte antigen typing of peripheral blood confirmed a Grade 2 GVHD. Clinical manifestations and diagnosis of GVHD following LT are discussed. While potentially under-recognized, clinicians should be aware of this rare but potentially fatal complication, as prompt intervention may improve outcomes in LT.

| Introduction|| |
Unlike graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT), GVHD after liver transplantation (LT) is a rare complication.[-3] GVHD develops when donor T-cells recognize cells from the recipient tissue as foreign antigens and initiate an immune attack on multiple organ systems. Solid organ transplants, such as small intestine or liver, contain more immunocompetent donor lymphocytes and are associated with a higher incidence of GVHD (5%–6% and 1%–2%, respectively). The mortality rate for GVHD of LT has been reported to be up to 85%. Prompt diagnosis for early intervention of GVHD after LT is difficult and challenging because the cutaneous manifestations are nonspecific and may mimic viral exanthem or adverse drug eruption. We report a case of a 60-year-old man with acute GVHD after orthotopic LT.
| Case Report|| |
A 60-year-old man visited the emergency department for generalized malaise, pruritic rashes, and fever for 1 week. He had a history of chronic hepatitis B with cirrhosis and stage three chronic kidney disease and received orthotopic LT for end-stage liver failure 1 month ago. The patient began receiving posttransplantation oral tacrolimus and prophylactic entecavir use since 1 month ago. On examination, he had a fever of 38.9°C and hyperpigmented oval-to-round macules and papules diffusely scattered on four limbs, especially on hands and feet [Figure 1]a, [Figure 1], [Figure 1]c. The initial impression was acute GVHD, but viral exanthem and drug reaction with eosinophilia and systemic symptoms were also considered. While the patient had a history of tacrolimus and entecavir drug use, both medications had low notoriety for cutaneous adverse reactions, and had been used for over 1 month, and thus, drug reaction was less favored.

Laboratory data were remarkable for leukopenia (1100 cells/mm3 with 79% neutrophils and 1% eosinophils), decreased platelet count (121,000 cells/mm3), and anemia (8.3 g/dL). Elevated serum creatinine level was noted, consistent with his baseline chronic kidney disease, while liver enzyme was within normal limit. Blood, stool, and urine cultures were negative. Serology and polymerase chain reaction (PCR) for cytomegalovirus (CMV), Epstein–Barr virus (EBV), and herpes simplex virus was negative. To confirm the diagnosis of GVHD, skin biopsy and human leukocyte antigen (HLA) typing of peripheral blood lymphocyte were performed. The biopsy specimen showed mild acanthosis with dyskeratotic cells, exocytosis, vacuolar degeneration of basal cells, melanin incontinence, and lymphocytes at the interface and around dermal vessels [Figure 1]d, which were consistent with Grade 2 GVHD. The HLA typing of peripheral blood lymphocytes also identified chimerism. Based on these findings, a diagnosis of GVHD was established.
Pulse steroid therapy combined with increased immunosuppressants with titrated dose of tacrolimus and newly added everolimus were given. Valganciclovir and entecavir were also used for prophylaxis of CMV infection and prevention of hepatitis B virus reactivation, respectively. Patient's GVHD was temporarily controlled, and he was discharged from our hospital. However, the patient subsequently was diagnosed with Pneumocystis jiroveci pneumonia with sepsis 1 month later and eventually expired due to multiple organ failure.
| Discussion|| |
GVHD is a multisystem disease that can occur after blood, bone marrow, or solid organ transplantation. GVHD after solid organ transplantation is rare but has a potentially lethal complication, especially in LT. GVHD occurs between 2 and 8 weeks after LT and often involves multiple organs, including the skin, gastrointestinal tract, and hematopoietic tissue., Skin rashes are usually the first manifestation, developing on an average of 48.3 days. A systematic review by Kim et al. described the dermatologic manifestations of GVHD as highly variable. Patients may present with pruritic erythematous to violaceous macules and papules with desquamation. The most common gastrointestinal symptom of GVHD is diarrhea caused by the destruction of the intestinal mucosa but can also be secondary to infectious causes or medications such as mycophenolate mofetil., Because the transplanted liver is the source of the donor T-lymphocytes, impaired liver function is not common. However, pancytopenia is regularly seen in patients with GVHD after LT. Normal liver function and presence of pancytopenia differentiate GVHD after LT from GVHD after HSCT., Differences between acute GVHD after LT and HSCT are described in [Table 1]. It is worth noting that pancytopenia and diarrhea have also been shown to be poor prognostic factors for GVHD after LT.

There are two risk factors that have been identified for GVHD after LT, including HLA matching between donor and recipient and an immunocompromised state in the recipient. Recipients receiving a well-matched graft have an increased risk of developing GVHD, especially in cases with one-way donor-recipient HLA-matching.,, The plausible mechanism is because alloreactive donor lymphocytes from a well-matched graft are less likely to be rapidly destroyed in the recipient. An immunocompromised state in the recipient, including old age, previous immunosuppression, and diabetes mellitus, has been shown to be another risk factor. Previous studies showed that patients >65 years at the time of LT were nine times more likely to develop GVHD than those aged <65 years.
Viral exanthem and drug eruption should be considered in the differential diagnoses because clinical and histopathologic features resemble the cutaneous manifestations of acute GVHD after LT. Opportunistic viral infections after transplantation, including CMV, EBV, and human herpes virus, can be detected by serology and PCR. Specific histopathologic findings of skin biopsy, such as intranuclear inclusions in CMV infection, may be useful for distinguishing viral diseases from GVHD. However, it is difficult to differentiate viral exanthem from GVHD if no serologic and histopathologic evidence of viral infections are detected. Therefore, prophylaxis with antiviral agents should be given in consideration of potential viral infection. To evaluate potential adverse drug eruption, comprehensive review of drug history needs to be taken for the assessment of drug causalities, such as ALDEN algorithm of drug causality assessment and the Naranjo algorithm.,
Skin biopsy and HLA typing of peripheral blood is helpful in making the diagnosis of GVHD after LT. Skin biopsy showing epidermal dyskeratosis with vacuolar degeneration of basal cells, exocytosis of lymphocytes, and melanin incontinence is highly suggestive of GVHD. Vacuolar interface changes can also be present around the hair follicle. However, the histopathologic features in skin are not pathognomonic for GVHD and are also present in drug eruptions. The identification of chimerism, which is defined as the presence of cells expressing donor antigens, in the peripheral blood is a useful early diagnostic aid. In addition, serial detection of the chimerism can predict evolving GHVD. In addition, fluorescence in situ hybridization with specific probes for the sex chromosomes to monitor the recipient to donor ratio is an alternative method for confirming the diagnosis of GVHD.
Till date, there is no standardized treatment for GVHD after LT. High-dose or pulse steroid therapy is used as the first-line treatment of acute GVHD after LT. Unfortunately, GVHD after LT is less responsive to corticosteroids than GVHD after HSCT. The combination with nonsteroid immunosuppression has also been used, including anti-thymocyte globulin or other immunosuppressants. Therapy with monoclonal antibodies, interleukin-2 and interleukin-12 antagonists and tumor necrosis factor-alpha inhibitors, may also play potential roles in future management.,, Despite these interventions, the mortality rate of GVHD after LT still remains high.
In summary, we report a case of GVHD occurring 1 month after orthotopic LT. The diagnosis of GVHD after LT was based on the clinical manifestation, histopathological evidence, and demonstration of chimerism. Taiwan has a large number of LTs, with approximately 3000 cases between 2003 and 2012. Given the estimated incidence of GVHD and the volume of LTs in Taiwan, this entity is likely under-diagnosed and under-reported. Therefore, clinicians should be aware of this rare but potentially fatal complication, as prompt detection and management of GVHD can contribute to better outcomes in LT.
The study was approved by the Institutional Review Board of Chang Gung Medical Foundation, in compliance with Taiwanese law (IRB no. 201901670B0).
