Introduction and History
Any discussion of the psychiatric aspects of pediatric transplantation must begin with a brief history of the field of pediatric transplantation itself. Both solid organ and bone marrow transplant procedures have made remarkable progress over the last 30 to 40 years, with pediatric technological expertise keeping pace with the rapid development of new and better means of keeping transplant patients healthy and highly functional. In fact, if one examines the relatively high morbidity and mortality rate of all forms of transplantation 30 years ago compared to the state of the art today, it perhaps makes sense that interest in the psychosocial and psychiatric wellbeing of transplant patients is a relatively new and still understudied aspect of the field.
The first solid organ transplant procedures in children involved cardiac transplant attempts in infants during the late 1960s. These patients lived at most a few days, and although physicians and scientists tried valiantly to understand the limits of these potentially life-saving procedures, the results were plagued by infection, organ failure, and graft rejection. The introduction of cyclosporine as an immunosuppressing agent in 1980 marked perhaps the beginning of a fundamental change in the outcome of these procedures. Although powerful and increasingly specific antibiotic and physiologic medications were vastly improving outcomes, medications such as cyclosporine made possible the resistance to graft rejection that paved the way for a substantially more normal existence for transplant recipients. Patients lived longer, fared substantially better, and transplant services became gradually more interested in the psychosocial development of the younger patients whose lives had been saved, but permanently altered, inherent in the transplant itself and in the treatment of subsequent complications makes the medical training of the consultation-liason psychiatrist ideally suited for this service.
In a similar fashion, bone marrow transplantation began as a desperate attempt to prevent the development of otherwise fatal conditions, most commonly hematological malignancies. Since its somewhat rocky beginnings, great strides have been made in this difficult and unique procedure. While the first bone marrow transplant procedures took place in the late 1960s, unlike solid organ transplant procedures, bone marrow transplantation had its genesis in the pediatric population. In addition, perhaps because of the severe isolation that very young patients must endure during bone marrow transplantation, attention to the psychosocial needs of these patients received greater initial emphasis than did solid organ procedures on similar-age patients. However, for both solid organ and bone marrow transplant procedures, transplant services are increasingly recognizing the need for participation by, and integration with, pediatric mental health specialists. In addition to assisting transplant services with decisions regarding suitability and preparation of the patient and family for the imminent surgery, problems such as medication compliance, maintaining a normal developmental trajectory, the onset and treatment of emerging psychiatric disorders, and the management of psychological aspects of the still frequent medical crises all involve active participation of child mental health services. Furthermore, our experience suggests that the understanding of the medical challenges inherent in the procedure itself and in the treatment of subsequent complications make the physician training of the consultation-liaison child psychiatrist ideally suited for this service.
All of these developments gave rise to the somewhat new field of transplant psychiatry. Early consultants such as Owen Surman at Massachusetts General Hospital and Margaret Stuber at UCLA paved the way for greater acceptance of the psychiatric needs of solid organ and bone marrow transplant recipients. Interestingly, as with other significant, chronic, and severe medical conditions, there is some evidence that attention to the psychiatric concerns of transplant patients became more palatable to medical and surgical services as the overall capacity to keep these patients healthy continued to improve (1).
This chapter will summarize the psychiatric aspects of pediatric solid organ and bone marrow transplant patients. We will focus on the evaluation and preparation of patients and their families for the procedure itself, on the management of the patient and family during and immediately following the procedure, and on the long-term management of these patients as they move forward in their lives. In many ways, pediatric transplant psychiatry epitomizes the fundamental aspects of good consultation-liaison work. The principal challenge for the transplant psychiatrist is achieving balance in the dual role of helping the patient and family maintain a normal developmental trajectory while at the same time assisting the transplant team with the often charged and intense emotions that accompany working with these young patients.
Psychiatric Similarities and Differences between Solid Organ and Bone Marrow Transplantation Procedures
Important Similarities
Patients who face either solid organ transplant or bone marrow transplant are gravely ill. Transplants are a viable option when other treatment modalities cannot prevent death or progressive, debilitating illness. Patients who require a new solid organ or organs, or patients who require bone marrow transplantation, are reckoning with the most basic of existential quandaries. If the patients are old enough, they will often be acutely aware of the risks to their life and wellbeing. They and their families are under enormous stress. Both patient populations must process the complex array of risks and benefits of multiple options and then make a decision about whether or not to proceed with a potentially life-threatening and most certainly life-changing treatment.
The risks of the surgery itself are difficult to contemplate, as is the meaning of the commitment to a lifetime of medications with both short- and long-term side effects. Both populations and their families will wonder about issues as immediate as whether academic and developmental progress will continue, and as distant as whether or not fertility will be at risk.
Immunosuppressive medications are still the mainstay of antigraft rejection treatment, and many patients experience neuropsychiatric side effects from those medications. Cyclosporine and tacrilomus, two major antirejection agents, as well as corticosteroids, have been associated with anxiety, depression, agitation, delirium, paranoia, potentially some cognitive changes, and worsening of preexisting psychiatric conditions. These effects will be discussed in detail below. The transplant psychiatrist must be aware of the potential for these side effects and monitor patients carefully.
Case Illustration 1: Side Effects of Immunosuppression
A 13-year-old boy with a history of autoimmune hepatitis and subsequent hepatic failure received a deceased donor liver transplant at age 12. Before his liver disease and surgery, he carried the psychiatric diagnoses of ADHD and an atypical mood disorder, and was treated with stimulant medications and atypical antipsychotics to prevent his often aggressive outbursts. Given the severity of his psychiatric disorder, his medication was continued throughout his perioperative course. However, after his transplant, he developed significant emotional lability that correlated with the addition of prednisone as a necessary part of his immunosuppressant regimen. This behavior was managed by increasing dosages of his atypical antipsychotic medications. As atypical agents are hepatically metabolized, increased monitoring of his liver function tests was necessary to ensure that the added psychotropics were not further compromising his graft.
In addition, in both populations of transplant recipients there is a high potential for drug–drug interactions. Many transplant recipients are on multiple agents, and these may affect each other with significant neuropsychiatric sequelae (refer to Chapter 6.1.1). The transplant psychiatrist may be the member of the team most likely to recognize these interactions given that vigilance regarding drug–drug interactions is a mainstay of psychopharmacology.
Case Illustration 2: Drug–Drug Interactions
An 18-year-old woman who underwent a deceased donor liver transplant for biliary atresia at age 2 presented to the pediatric transplant service for ongoing management of her transplant, as well as for care of her inflammatory bowel disease. Important psychiatric issues included diagnoses of depression and anxiety for which she was prescribed clonazepam and paroxetine. Her history was also significant for recreational marijuana use and a complex partial seizure disorder. Finally, she had persistent difficulties with medication compliance, often stopping her anti-rejection medications. After her arrest for possession at age 19, she abruptly stopped using marijuana, and almost immediately thereafter experienced another round of graft rejection for which she was admitted to the hospital with the assumption that she had stopped taking her medications. A low tacrolimus level made her insistence that she was indeed compliant all the more puzzling. The transplant service eventually concluded that the sudden withdrawal of marijuana likely increased gastric motility, such that she absorbed less immunosuppressing agents than before and thus was not able to maintain her graft without immediate treatment with steroids and a higher overall immunosuppressive regimen. Appropriate adjustments in immunosuppressant dosages adequately addressed the problem, and the patient was able to maintain her graft.
Apart from the psychiatric effects of the immunosuppressing agents themselves, recipients of transplant surgery often carry all of the incertainty and psychological distress that characterize the onset of a chronic medical condition. Indeed, there is mounting evidence that both bone marrow and solid organ recipients are at risk for posttraumatic syndromes and in some instances will meet full criteria for posttraumatic stress disorder. Mental health members of transplant services need to watch for these symptoms, both in patients and in their families. There is in fact some evidence that the extent to which parents feel traumatized correlates with the psychological and medical wellbeing of the pediatric transplant recipient (2,3). These challenges, along with the normal adolescent drive toward independence and separation, contribute to the high rate of medication noncompliance that characterizes the most common cause of graft rejection in pediatric populations.
The issue of posttraumatic syndromes stemming from severe medical conditions and intense treatment regimens deserves special mention. As mentioned above, there is growing evidence that children who undergo frequent and often noxious treatments for chronic medical illness can develop subclinical traumatic reactions or the full syndrome of posttraumatic stress disorder (PTSD). A recent review by Stuber and colleagues (3) suggested that parental trauma was a strong predictor of patient traumatic reaction among medically ill pediatric cancer patients. Similarly, in pediatric transplant patients, new research stresses that the sense among families and patients of the seriousness of the illness, regardless of how physicians tended to view the severity of the condition, is a potent predictor of pathological stress reactions (2). As one might expect, sudden events, such as abrupt rupture of esophageal varicies in patients with portal hypertension, are associated with more traumatic responses than are insidious serious illnesses, such as slowly progressive cardiomyopathies. These data stress the need for clear, straightforward, developmentally and educationally tailored discussions with patients and families about the risks of the current condition. Assumptions that families will view their predicament exactly as the transplant team assesses the severity of the situation can lead to gross misunderstandings, the possibility of significant psychological stress for patients and caregivers, and potentially serious psychiatric syndromes such as PTSD or depression.
For all patients who undergo transplant procedures, there exists a difficult equilibrium in allowing their children to develop and grow as normally as possible, while remaining constantly vigilant and increasingly anxious about the possibility of graft rejection. Graft rejection is not always obvious, though in some instances it is preceded by a clearly worsening course. In other situations, however, possible graft rejection is discovered on routine laboratory tests, leading to an element of hypervigilance that both patient and parents can experience and that is neither helpful nor healthy. The transplant psychiatrist can be helpful in managing this particular form of anxiety. His or her unique understanding of transplant medicine may encourage a frank discussion by the patient and family about their heightened concerns.
Finally, given the natural epidemiology of childhood psychosocial and psychiatric difficulties, there will inevitably be some children and adolescents who will suffer psychological difficulties not directly related to their transplant, but whose transplant will complicate effective treatment. For these patients, though no clear guidelines exist, keeping in mind drug–drug interactions, the means by which medications are metabolized, and the possible neuropsychiatric side effects of immunosuppressants are all important considerations. In general, one should prescribe psychotropic agents in lower initial dosages and monitor closely both the mental status exam and laboratory values that might suggest adverse drug effects. In addition, one cannot underestimate the effectiveness of supportive, psychodynamic, and behavioral interventions for some patients. Undergoing and living with a transplant is trying at best, and for children and adolescents, the therapist can help them cope with shaping a developing identity, such that they do not necessarily assume a sickly sense of self.
Important Differences
In spite of the similarities noted above, there are differences to note as well. Patients who require solid organ transplant (heart, kidney, lung, liver) often see their disease as limited to that organ. Bone marrow transplantation is performed for patients who have an underlying systemic illness, i.e., cancer. As cancer itself carries particular emotional valence in our culture, patients receiving transplant procedures for malignancies may require extra attention given the associated stress that the diagnosis and all of its cultural signifiers can entail. Although some pediatric patients may receive solid organ transplantation for cancer, this is less common than for organ malformation or metabolic and autoimmune diseases. Additionally, the isolation associated with bone marrow transplantation is particularly harrowing for all patients, and attention to the developmental needs of these patients is crucial for their psychological and medical wellbeing.
Transplantation, is a final common pathway for a group of heterogeneous and not always related conditions. This poses a special challenge to the child psychiatrist working with the transplant team. To be effective, the child psychiatrist must have an understanding of the medical and surgical components of the underlying disease as well as an understanding of the risks and benefits of the transplant itself. He or she must then tailor any treatment to the temperament and preexisting psychological and developmental challenges facing the child and the family, keeping in mind the inherent limitations posed by both the disease and the treatment. As many patients are quite young, there is the added challenge of balancing the involvement of an extended family and multiple systems of care. The work is complex but immensely rewarding.
The Pretransplantation Evaluation
The child and adolescent psychiatrist plays an important and complex role in the evaluation of the child who is approaching transplantation. Initially, the psychiatrist is responsible for conducting a thorough psychiatric evaluation of the patient and family. In addition, the psychiatrist must be familiar with the medical problems facing the patient, both before and after surgery, in order to educate the family about the risks and benefits or transplantation and to assess the family’s ability to provide informed consent. The psychiatrist also acts as a liaison between the family and the transplant team. The family will need support, direction, and clarification of the transplant team’s expectations and concerns. The team in turn will also need support, direction, and sometimes interpretation of the family’s behavior. The psychiatrist may also serve to focus the team’s attention on ethical conflicts that may arise, particularly those that involve directed living donation by a related or unrelated donor.
