Fatal graft-versus-host disease after unrelated cadaveric liver transplantation due to donor/recipient human leucocyte antigen matching

Improved survival after LTx-associated acute GVHD with mAb therapy targeting IL2RAb and soluble TNFAb: Single-center experience and systematic review

Acute graft-versus-host disease (GVHD) after liver transplant (LTx) is a rare complication with a high mortality rate. Recently, monoclonal antibody (mAb) treatment, specifically with anti-interleukin 2 receptor antibodies (IL2RAb) and anti-tumor necrosis factor-α antibodies (TNFAb), has gained increasing interest. However, evidence is mostly limited to case reports and the efficacy remains unclear. Here, we describe 5 patients with LTx-associated GVHD from our center and provide the results of our systematic literature review to evaluate the potential therapeutic benefit of IL2RAb/TNFAb treatment. Of the combined population of 155 patients (5 in our center and 150 through systematic search), 24 were given mAb (15.5%)-4 with TNFAb (2.6%) and 17 with IL2RAb (11%) ("mAb group")-and compared with patients who received other treatments (referred to as "no-mAb group"). Two-sided Fisher exact tests revealed a better survival when comparing treatment with mAb versus no-mAb (11/24 vs 27/131; P = .018), TNFAb versus no-mAb (3/4 vs 27/131; P = .034), and IL2RAb versus no-mAb (8/17 vs 27/131; P = .029). This systematic review suggests a beneficial effect of mAb treatment and a promising role for TNFAb and IL2RAb as a first-line strategy to treat LTx-associated acute GVHD.

Dermatologic manifestations of solid organ transplantation-associated graft-versus-host disease: A systematic review

BACKGROUND

Graft-versus-host-disease (GVHD) after solid organ transplantation (SOT) is extremely rare.

OBJECTIVE

To investigate the dermatologic manifestations and clinical outcomes of SOT GVHD.

METHODS

Systematic literature review of SOT GVHD.

RESULTS

After full-text article review, we included 61 articles, representing 115 patients and 126 transplanted organs. The most commonly transplanted organ was the liver (n = 81). Among 115 patients, 101 (87.8%) developed skin involvement. The eruption appeared an average of 48.3 days (range, 3-243 days) posttransplant and was pruritic in 5 of 101 (4.9%) cases. The eruption was described as morbilliform in 2 patients (1.9%), confluent in 6 (5.9%), and desquamative in 4 (3.9%) cases. In many cases, specific dermatologic descriptions were lacking. The mortality rate was 72.2%. Relative time of death was reported in 23 patients who died during the follow-up period. These patients died an average of 99.2 days (range, 22-270 days) posttransplant, or 50.9 days after the appearance of dermatologic symptoms. Frequent causes of death were sepsis and multiorgan failure.

LIMITATIONS

Incomplete descriptions of skin findings and potential publication bias resulting in publication of only the most severe cases.

CONCLUSIONS

GVHD is a potentially fatal condition that can occur after SOT and often presents with a skin rash. We recommend that dermatologists have a low threshold to consider and pursue this diagnosis in the setting of post-SOT skin eruption.

Graft Versus Host Disease After Liver Transplantation in Adults: A Case series, Review of Literature, and an Approach to Management

BACKGROUND

Graft-versus-host-disease (GVHD) after liver transplantation (LT) is a deadly complication with very limited data on risk factors, diagnosis and management. We report a case series and a comprehensive review of the literature.

METHODS

Data were systematically extracted from reports of GVHD after LT, and from the United Network for Organ Sharing database. Group comparisons were performed.

RESULTS

One hundred fifty-six adult patients with GVHD after LT have been reported. Median time to GVHD onset was 28 days. Clinical features were skin rash (92%), pancytopenia (78%), and diarrhea (65%). Six-month mortality with GVHD after LT was 73%. Sepsis was the most common cause of death (60%). Enterobacter bacteremia, invasive aspergillosis, and disseminated Candida infections were frequently reported. Recipient age over 50 years is a risk factor for GVHD after LT. Hepatocellular carcinoma was overrepresented, whereas chronic hepatitis C was underrepresented, in reported United States GVHD cases relative to all United Network for Organ Sharing database LT cases. Mortality rate with treatment of GVHD after LT was 84% with high-dose steroids alone, 75% to 100% with regimens using dose increases of calcineurin inhibitors, and 55% with IL-2 antagonists. Mortality was 25% in small case series using the CD2-blocker alefacept or TNF-α antagonists.

CONCLUSIONS

Age older than 50 years and hepatocellular carcinoma appear to be risk factors for GVHD. Hepatitis C may be protective. High-dose steroids and calcineurin inhibitors are ineffective in the treatment of GVHD after LT. CD2-blockers and TNF-α antagonists appear promising. We propose a diagnostic algorithm to assist clinicians in managing adults with GVHD after LT.
