Incidence of Hypertension Among Children Treated With Adrenocorticotropic Hormone (ACTH) or Prednisolone for Infantile Spasms

Clinical practice recommendations for kidney involvement in tuberous sclerosis complex: a consensus statement by the ERKNet Working Group for Autosomal Dominant Structural Kidney Disorders and the ERA Genes & Kidney Working Group

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the presence of proliferative lesions throughout the body. Management of TSC is challenging because patients have a multifaceted systemic illness with prominent neurological and developmental impact as well as potentially severe kidney, heart and lung phenotypes; however, every organ system can be involved. Adequate care for patients with TSC requires a coordinated effort involving a multidisciplinary team of clinicians and support staff. This clinical practice recommendation was developed by nephrologists, urologists, paediatric radiologists, interventional radiologists, geneticists, pathologists, and patient and family group representatives, with a focus on TSC-associated kidney manifestations. Careful monitoring of kidney function and assessment of kidney structural lesions by imaging enable early interventions that can preserve kidney function through targeted approaches. Here, we summarize the current evidence and present recommendations for the multidisciplinary management of kidney involvement in TSC.

Cost-effectiveness of adrenocorticotropic hormone injection and oral prednisolone in patients with West syndrome: A comparative analysis

Objectives

This study aims to compare the cost-effectiveness of oral prednisolone and adrenocorticotropic hormone injection in West syndrome patients, the two most common hormonal therapies used for this condition.

Materials and Methods

In this prospective and observational study, we documented sociodemographic, epilepsy, and development-related variables at baseline and up to 6 months after starting hormonal therapy, in all consecutive eligible patients of WS between August 2019 and June 2021, apart from the direct medical and non-medical costs and indirect health-care costs. We selected cost per quality-adjusted life-year (QALY) gained, per one patient with spasm freedom, one positive responder (>50% reduction in spasms), one relapse-free patient, and one patient with development gain. We determined whether incremental cost-effectiveness ratio for these parameters crossed the threshold value in base-case analysis and alternate scenario analysis.

Results

Out of 52 patients screened, 38 and 13 patients enrolled in ACTH and prednisolone group. On D28, 76% and 71% achieved spasm cessation (P = 0.78) and the total cost of treatment was INR 19783 and 8956 (P = 0.01), in ACTH and prednisolone group respectively. For all pre-specified parameters, the cost/effectiveness ratios including cost/QALY gain were higher in ACTH group and the corresponding ICER values for all these parameters crossed the threshold cost value of INR 148,777 in base-case analysis and also in alternative scenario analysis.

Conclusion

Treatment with oral prednisolone is more cost-effective as compared to ACTH injection for children with WS.

Cardiometabolic outcomes in children and adolescents with West syndrome

BACKGROUND

West syndrome is a convulsive disorder of infancy with unique seizures and a characteristic background electroencephalograph pattern. Adrenocorticotropic hormone (ACTH) is effective in spasm cessation, yet metabolic consequences of this therapeutic agent in childhood have not been published.

METHODS

In this observational study we explored the cardiometabolic outcomes of 117 children with West syndrome (78 ACTH-treated and 39 non-ACTH-treated) monitored at a single medical center from 1995 to 2019 (median follow-up 7.2 years). Outcomes included the prevalence of cardiometabolic derangements (obesity, hypertension, and dyslipidemia) during infancy (< 2 years), early childhood (2-6 years), and childhood/adolescence (6-18 years).

RESULTS

The rates of metabolic derangements during infancy in the West syndrome cohort were high compared to childhood/adolescence (obesity 27.3 % vs. 3.3 %, [p = 0.010], diastolic hypertension 48.8 % vs. 5.1 % [p < 0.001], hypertriglyceridemia 71 % vs. 40 % [p = 0.008], low high-density lipoprotein cholesterol [HDL-c] 54.2 % vs. 12.9 % [p = 0.001], and elevated triglycerides/HDL-c ratios 62.5 % vs. 12.9 % [p < 0.001]). The proportion of systolic and/or diastolic blood pressure levels categorized as hypertensive was 58.5 % during infancy, 48.1 % during early childhood, and 26.3 % during childhood/adolescence. ACTH-treated patients had higher weight and weight-to-length z-scores and higher triglyceride levels during infancy compared to non-ACTH-treated patients (p = 0.008, p = 0.001, and p = 0.037, respectively), and higher triglyceride levels during early childhood (p = 0.050), with no significant group differences during childhood/adolescence.

CONCLUSIONS

Children with West syndrome apparently have an increased prevalence of cardiometabolic derangements more pronounced in infants and in ACTH-treated patients. These findings highlight the need to monitor these children for cardiometabolic derangements, even though these cardiometabolic abnormalities are transitory and tend to decrease with time. The health implications of cardiometabolic derangements during critical windows of growth and development warrant further investigation.

Teleneurology based management of infantile spasms during COVID-19 pandemic: A consensus report by the South Asia Allied West syndrome research group

With telehealth services rescuing patients with chronic neurological disorders during the COVID-19 pandemic, there is a need for simplified teleneurology protocols for neurological disorders in children. Infantile spasms is an epileptic encephalopathy where treatment lag is a significant predictor of outcome. It is one such condition where telemedicine can make a remarkable difference when in-person consultations are delayed or are not possible. However, the adverse effect profile of the first-line therapeutic options, the need for frequent follow-up, underdeveloped telemedicine services, lack of a rational protocol, poor awareness about infantile spasms, a lesser level of parental understanding, and scarcity of pediatric neurologists are the major hurdles in developing countries. This paper provides a teleneurology based approach for the management of infantile spasms in developing countries during the COVID-19 pandemic. The cornerstones of this approach include the fundamental principles of management of infantile spasms, decentralization of patient care to local health providers, efforts for improving sensitivity and specificity of diagnosis, early initiation of first-line therapeutic options, and constant motivation of parents and local health providers to be vigilant for therapeutic response, adverse effects of therapy, and infections.

Neutrophil to lymphocyte rate and serum prealbumin maybe predictors for abnormal high blood pressure caused by adrenocorticotropic hormone therapy in children with epileptic spasms: two cases report

Epileptic spasms are a catastrophic form of epilepsy. When epileptic spasms occur under 2-year-old, they may be also called “infantile spasms”. Adrenocorticotropic hormone (ACTH) is recommended as first line intervention for the treatment of epileptic spasms without tuberous sclerosis complex. The chief risks of ACTH therapy are immunosuppression and hypertension. We reported rare cases of abnormal high blood pressure in two male epileptic spasms patients during ACTH therapy. Both patients’ blood pressure reached a high blood pressure stage 2 on the 9th day and 10th day of ACTH treatment, respectively. The blood pressure returned to normal range after the drug dosage was reduced or stopped. The lower level of neutrophil%, neutrophil count, and a higher level of lymphocyte%, lymphocyte count and prealbumin than normal range were observed in both patients before ACTH therapy. The neutrophil to lymphocyte rate might be a predictor for high blood pressure among patients treated with ACTH. The rates of both patients were under 0.50 (0.42 for Case 1 and 0.17 for Case 2). We reported the documented cases in two Chinese pediatric patients who suffered from epileptic spasms treated with ACTH resulted in abnormal high blood pressure, which could be predicted by using neutrophil to lymphocyte rate. We also mentioned serum prealbumin might be another predictor. More clinical data is required to elucidate the relationship between serum prealbumin level and blood pressure.
