Clinical Characteristics of Children and Adolescents Undergoing Hematopoietic Cell Transplantation Who Develop Oral Mucositis

Utilization of Photobiomodulation for the Prevention and Treatment of Oral Mucositis

Background: Oral mucositis is a significant and common toxicity experienced by patients who receive high-dose chemotherapy as a preparatory regimen for a hematopoietic cell transplant (HCT). Photobiomodulation (PBM) has been found to be feasible with significant efficacy in preventing the progression of oral mucositis in adult patients undergoing HCT. The purpose of this study was to determine the feasibility and efficacy of PBM in pediatric oncology patients undergoing HCT. Method: Forty children and adolescents admitted to the transplant unit for an allogeneic HCT for acute lymphoblastic leukemia or acute myeloid leukemia were treated daily at six sites until day + 20 or engraftment. Results: There were 1,035 patient encounters, with successful treatment of four or more sites during 979 patient encounters for a feasibility 93.3% CI [0.926, 0.039]. We had estimated a meaningful effect size of 20% for PBM and estimated 51% of patients treated with PBM would have at least one day or more of Grade 3 mucositis. The rate of patients who received PBM and developed Grade 3 mucositis was 20% CI [0.091, 0.356]. Patients treated with PBM had fewer days of hospitalization (p = .009) and less severe mucositis in comparison to the matched control group (p = .03). Conclusion: PBM is feasible and effective in preventing and treating oral mucositis and is now supported by the Children's Oncology Group for prevention and treatment of oral mucositis in patients undergoing an allogeneic HCT or receiving head/neck radiation.

Incidence, severity, and temporal development of oral complications in pediatric allogeneic hematopoietic stem cell transplant patients - a multicenter study

PURPOSE

Oral mucositis is a common complication for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) and causes pain and difficulties in functions like eating and swallowing, resulting in lower quality of life and greater need of treatment with opioids and parenteral nutrition. This prospective multicenter study focused on pediatric recipients of HSCT in the neutropenic phase concerning oral complications, timing, severity, and patient experience.

METHODS

The cohort comprised 68 patients, median age 11.1 years (IQR 6.3) receiving allogeneic HSCT at three clinical sites. Medical records were retrieved for therapy regimens, concomitant medications, oral and dental history, and subjective oral complaints. Calibrated dentists conducted an oral and dental investigation before HSCT. After HSCT graft infusion, study personnel made bedside assessments and patients filled out a questionnaire once or twice a week until neutrophil engraftment.

RESULTS

We followed 63 patients through the neutropenic phase until engraftment. 50% developed oral mucositis of grades 2-4. Peak severity occurred at 8-11 days after stem cell infusion. Altogether, 87% had subjective oral complaints. The temporal distribution of adverse events is similar to the development of oral mucositis. The most bothersome symptoms were blisters and oral ulcerations, including mucositis; 40% reported severe pain and major impact on activities of daily living despite continuous use of opioids.

CONCLUSION

This study highlights the burden of oral complications and their negative effect on the health and quality of life of HSCT recipients.

Pain and discomfort in children with gastrostomy tubes - In the context of hematopoietic stem cell transplantation

BACKGROUND

In children with malignant and severe non-malignant disorders undergoing hematopoietic stem cell transplantation (HSCT), treatment related pain and discomfort are common. Food consumption may become troublesome, making the use of a gastrostomy tube (G-tube) necessary and resulting in complications, why the purpose was to explore pain and discomfort during the transplantation and post-transplantation time.

METHODS

This was a mixed methods study where data were collected along the child's total health-care process between 2018 and 2021. Questions with fixed answer options were used, simultaneously, semi-structured interviews were performed. In total, sixteen families participated. Descriptive statistics and content analysis were used to describe analysed data.

FINDINGS

Intense pain was common during the post-surgery phase, especially in conjunction with G-tube care, which is why the children needed support to manage the situation. After the post-surgery phase when the skin has healed, most of the children experienced minor to no pain or bodily discomfort, why the G-tube became a well-functioning and supportive tool in daily life.

CONCLUSIONS

This study describes variations in and experiences of pain and bodily discomfort in conjunction with G-tube insertion in a unique sample of children who had undergone HSCT. In conclusion, the children's comfort in daily life after the post-surgery phase seemed to be only marginally affected by G-tube insertion. Children with severe non-malignant disorders seemed to experience a higher frequency and intensity of pain and bodily discomfort due to the G-tube than children with malignant disorders.

PRACTICE IMPLICATIONS

The paediatric care team need competence in assessing G-tube related pain and awareness that experiences may differ depending on the child's disorder.

Changes in Central Line–Associated Bloodstream Infection (CLABSI) Rates Following Implementation of Levofloxacin Prophylaxis for Children and Adolescents With High-Risk Leukemia

Background: Despite initiatives to reduce central line–associated bloodstream infection (CLABSI), children and adolescents with hematologic malignancies, as well as those with relapsed disease, remain at the greatest risk for infection. This single-institution project evaluated changes in CLABSI rates following implementation of antibacterial prophylaxis with levofloxacin for patients with high-risk hematologic malignancies. Methods: Positive blood culture events meeting National Health Safety Network surveillance criteria to be classified as CLABSIs from January 1, 2006, to December 31, 2019, were included. Data were organized into four time periods for comparison based on implementation of CLABSI-reduction interventions. Conditional Poisson regression models were used to evaluate the effect of time (intervention period) on CLABSI rates with post hoc Tukey pairwise comparisons between each of the four time periods. Results: From 2006 and 2019, 227 patients experienced 310 CLABSIs. Clinically important decreases in CLABSI rates from baseline (4.84 per 1,000 line days) occurred with implementation of Children's Hospital Association (CHA) bundles (3.29 per 1,000 line days); however, this difference was not significant ( p  =  .16). CLABSI rates decreased from baseline with the addition of formalized supportive cares (2.66 per 1,000 line days; incidence rate ratio [IRR]  =  0.60; p < .01), and with the use of antibacterial prophylaxis (1.66 per 1,000 line days; IRR  =  0.35; p < .01). Post hoc comparisons indicated decreased CLABSI rates with the use of antibacterial prophylaxis compared with CHA bundles alone (IRR  =  0.49; p  =  .011) and CHA bundles plus formalized supportive cares (IRR  =  0.58; p  =  .046). Discussion: Results demonstrate sustained success using a practice-based evidence approach to guide CLABSI-reduction interventions. Follow-up research, applying machine learning algorithms, may identify additional risk factors and inform future interventions.

The Association Between Pain Relief Using Video Games and an Increase in Vagal Tone in Children With Cancer: Analytic Observational Study With a Quasi-Experimental Pre/Posttest Methodology

Background

Patients with secondary pain due to mucositis after chemotherapy require treatment with morphine. Use of electronic video games (EVGs) has been shown to be an effective method of analgesia in other clinical settings.

Objective

The main objective of this study was to assess the association between the use of EVGs and the intensity of pain caused by chemotherapy-induced mucositis in pediatric patients with cancer. The secondary objective was to assess the association between changes in pain intensity and sympathetic-parasympathetic balance in this sample of pediatric patients.

Methods

Clinical records were compared between the day prior to the use of EVGs and the day after the use of EVGs. The variables were variations in pupil size measured using the AlgiScan video pupilometer (IDMed, Marseille, France), heart rate variability measured using the Analgesia Nociception Index (ANI) monitor (Mdoloris Medical Systems, Loos, France), intensity of pain measured using the Numerical Rating Scale (score 0-10), and self-administered morphine pump parameters.

Results

Twenty patients (11 girls and nine boys; mean age 11.5 years, SD 4.5 years; mean weight 41.5 kg, SD 20.7 kg) who met all the inclusion criteria were recruited. EVGs were played for a mean of 2.3 (SD 1.3) hours per day, resulting in statistically significant changes. After playing EVGs, there was significantly lower daily morphine use (before vs after playing EVGs: 35.9 vs 28.6 µg/kg/day, P=.003), lower demand for additional pain relief medication (17 vs 9.6 boluses in 24 hours, P=.001), lower scores of incidental pain intensity (7.7 vs 5.4, P=.001), lower scores of resting pain (4.8 vs 3.2, P=.01), and higher basal parasympathetic tone as measured using the ANI monitor (61.8 vs 71.9, P=.009). No variation in pupil size was observed with the use of EVGs.

Conclusions

The use of EVGs in pediatric patients with chemotherapy-induced mucositis has a considerable analgesic effect, which is associated physiologically with an increase in parasympathetic vagal tone despite lower consumption of morphine.
