Abstract

Background

Graft-versus-host disease (GVHD) is a rare but serious complication after pediatric liver transplantation (LTx). Early diagnosis is difficult due to nonspecific presenting symptoms and non-pathognomonic skin histopathological features. The aim of this article was to describe a case of pediatric GVHD after LTx and to review available data on pediatric GVHD highlighting the diagnostic difficulty. We also propose a diagnostic algorithm to improve the diagnostic capability and increase clinical awareness about this potentially fatal condition.

Methods

We did a comprehensive literatures review on studies on GvHD following pediatric LTx between 1990 and February 2021, chimerism study by short tandem repeat (STR), HLA typing by sequence-specific oligonucleotide (SSO) method, and flowcytometry crossmatch.

Results

Our search yielded 23 case reports. The most common clinical manifestations were fever and rash (91%) followed by diarrhea. Mortality rate was 36.8% mainly due to sepsis and organ failure. Diagnosis was challenging and chimerism study to confirm donor engraftment was performed on only half of the cases. Prevalence of “donor dominant HLA one-way matching” typically occurs in homozygous parents-to-child transplantation was 75% in cases with HLA testing.

Conclusion

So far, there are no available standard diagnostic criteria for GVHD following pediatric LTx. Recognition of multiple risk factors through proper laboratory assessment can predict the occurrence, and early chimerism study can confirm suggestive clinical manifestation. The strong likelihood of developing GVHD in “donor one-way HLA match” and the severe problems imposed by this complication may justify avoidance of HLA homozygous parent's donation.

CONFLICT OF INTEREST

The authors confirm that there are no conflicts of interest.
