Categorized examples of clinical case reports and trials of hepatocyte transplantation
| Patients | Disease | Procedure | Cells | Outcome | Reference |
|---|---|---|---|---|---|
| Small number of engrafted hepatocytes lead to sufficient repopulation due to hepatocytic injury | |||||
| Female 64 yo | Acute liver failure due to ingestin of amanita phalloides mushrooms | Portal vein injection | 8 billion cryopreserved cells. Viability ~62% measured with Trypan blue. | Ammonia, billirubin decreased gradually. Eight weeks after transplant, normal liver architecture and normal blood flow was seen. Physicians concluded full recovery. | Schneider et al. 2006 [82] |
| Small number of engrafted hepatocytes needed to provide therapeutic benefit | |||||
| Male | Factor VII deficiency | Inferior mesenteric vein injection | 1.09 billion cryopreserved | Requirement of exogenous protein diminished to 20% dose previous to transplant. Remission began at 6 mos. Received OLT. | Dhawan et al. 2004 [83] |
| Male | Factor VII deficiency | Inferior mesenteric vein injection | 2.18 billion fresh and cryopreserved | Requirement of exogenous protein diminished to 20% dose previous to transplant. Remission began at 6 mos. Received OLT. | |
| Female 9 yo | Crigler-Najjar | 7.5 billion cells (5% liver mass) | 50–65% reduction, remission at 3mo. Possible rejection. | Ambrosino et al. 2005 [84] | |
| Female 9 yo | Crigler-Najjar | Venous injection | 18 infusions over 5mo, total 4% of liver mass (6.1 billion cells) | Bilirubin reduced from 17.5 to 13.6, remission at 6mo | Lysy et al. 2008 [42] |
| Female 1 yo | Crigler-Najjar | Venous injection | 14 infusions over 15d, total of 8.6% of liver mass (2.6 billion) | Billirubin reduced from 17.6 to 13.3, remission at 4mo | |
| Male 6 yo | Phenylketoneurea (PKU) | 2.5 billion cells over 2 infusions | Phenylalanine decreased from 11.1 to 3.5 | Smets et al. 2011 [85] | |
| Female 4 mos | Carbamoyl-phosphate synthetase 1 (CPS1) deficiency | Portal vein by recanalization of the umbilical vein | 689 million viable cells over 3 infusions within 26hrs of 5GY HIR | Continued to experience episodes of high ammonia | Soltys et al. 2017 [50] |
| Male 7 mos | OTC | 2 billion cells over 4 infusions within 16hrs of 7.5GY HIR | Tolerated protein from day 20 to day 84, when ammonia acutely elevated | ||
| Female 27 yo | PKU | 5 billion cells over 3 infusions after 10GY HIR | PHE reduced by 36% for more than a year | ||
| Male 14 mos | Urea cycle disease (Ornithine transcarbamylase (OTC) deficiency) | Portal vein injection | 2.4 billion (6%) | Reduction in ammonia for 2mos. Psychomotor development improved. Eventually underwent OLT. | Stephenne et al. 2005 [86] |
| Female 3.5 yo | Argininosuccinate Lyase deficiency | Portal vein injection | 3.7 billion (9%) | Psychomotor advances acquiring fecal and urinary continence, could dress alone, and perform difficult puzzle exercises and ammonia decreased 50% and remained low for at least a year. Repopulation measured with Y-chromosome FISH showed 19% repopulation at 8 months, 12.5% at 12 months. | Stephenne et al. 2006 [87] |
| Massive repopulation is is required because toxic metabolite is generated in host hepatocytes | |||||
| Female 4 yo | Infantile Refsum disease, peroxisomal biogenesis disease | spleno-mesenteric confluent injection (venous injection) | 2 billion cells (5%). Half fresh half cryopreserved. | Resolution of cholestasis, metabolite decreased by 40%. Engraftment seen on biopsy. Reduction in abnormal metabolites maintained until end of measurement at 18 mos. | Sokal et al. 2003 [49] |
