Combined Immune Deficiency

Infants with severe combined immune deficiency (SCID) typically present in the first few months of life with severe, recurrent, opportunistic infections, and without definitive treatment the condition is invariably fatal (Gaspar et al. 2013). Many centres believe that protective isolation is required for treatment of SCID patients once diagnosed, and the isolation protocol varies across institutions. This paper describes the isolation protocol for SCID requiring hematopoietic stem cell transplant (HSCT) that has been utilized at our institution for over the last 25 years. We believe that the profound immunodeficiency in SCID patients warrants a more restrictive treatment to limit the morbidity and mortality associated with HSCT. With this protocol, we have seen a very low infection rate in and have a very good survival rate for our SCID population.

Background Hemophagocytic lymphohistiocytosis (HLH) is a severe life threatening hyper-inflammatory syndrome of abnormal immune activation and dysregulation if untreated. The 5-year probability of survival (pSu) obtained from HLH registries and treatment protocols HLH-94 and HLH-2004 ranges from 21%-64%, with improved 5-year pSu of up to 70% following hematopoietic stem cell transplant (HSCT) (Arico et al., Trottestam et al., Bergsten et al.). Despite significant advances in the management of HLH over time, survival remains low and the extent of disease morbidity and healthcare utilization is poorly characterized. In this study, we sought to investigate morbidity, mortality, and the healthcare burden in children and adolescents with HLH who underwent HSCT. Methods Using the Pediatric Health Information System (PHIS) database, we identified patients under the age of 21 years admitted between 01/01/2004 and 09/30/2018 with a primary or secondary ICD-9 or ICD-10 diagnosis codes for HLH, as well as concurrent medication charges for both dexamethasone and etoposide in the same encounter. We then identified the patients who underwent HSCT to further analyze them. We abstracted data on demographics, hospitalizations, HSCT related complications, mortality, resource utilization and costs. Results were summarized using descriptive statistics. Time to HSCT was calculated as elapsed time from the admission date of the initial encounter to the date of the encounter in which there was a procedure code for HSCT. Time to mortality event was calculated as elapsed time from the admission date of the initial encounter to the discharge date of the encounter in which mortality occurred. The PHIS database provides an encrypted patient medical record number; thus, we were able to follow patients over time. This allowed for a better visualization of the patient's hospitalizations trend over 14 years. Results A total of 493 patients met inclusion criteria for HLH during the study period from 52 children's hospitals. The majority of patients (n = 284, 58%) were less than 5 years of age. Of these, 136 patients (28%) underwent HSCT with 155 hospital encounters, including readmissions. The median age at the time HSCT was 2 years (IQR; 0-9 years) and there were 82 males (60%). The median time to HSCT was 126 days (IQR: 75-193 days) and the average length of stay for the initial HSCT hospitalization was 61.1 days. Median initial HSCT hospitalization cost was $463,630 (IQR; 230,795 - 558,533). ICU care was required for 71 (46%) of patients. Overall, 91 (67%) patients developed transplant-related complications, which included infections, sinusoidal obstruction syndrome or graft versus host disease (Table 1). Mortality after HSCT was 22% (n=30) with an increased mortality observed with advanced age at the time of HSCT (Figure 1). The median time to death after the initial HSCT admission was 65 days (IQR; 56-94 days). Conclusion This is a large in-patient cohort of pediatric patients with HLH who underwent HSCT in the US. We observed an improved overall mortality after HSCT in this population compared to previous studies. However, morbidity (particularly from infections) and heath care resource utilization remain high. This stresses the importance of novel therapeutic approaches to improve not only patient survival but also long-term quality of life. Planned future analysis of this database will be aimed at assessing treatment variability; morbidity and mortality by treatment regimen, time to HSCT, and HSCT preparative regimen; and risk factors associated with mortality in pediatric patients with HLH who do and do not undergo HSCT.
