Evaluation of the effectiveness of prophylactic oral vitamin D (cholecalciferol) in children with sickle cell disease

Bone Disease among Children with Sickle Cell Disease: A Scoping Review of Incidence and Interventions

Background

Children with sickle cell disease (SCD) are more likely to have deficient serum levels of vitamin D for bone metabolism. However, appropriate interventions are essential to prevent its progression and alleviate symptoms.

Purpose

The aim of this study is to determine interventions for managing bone disease in children with SCD.

Methods

This study uses a scoping review. A literature review was conducted using PubMed, CINAHL, ScienceDirect, Scopus, and Google Scholar search engines. The study was eligible for inclusion if it included articles published from 2013 to 2023, full-text, and original study design. Study quality was assessed using the Joanna Briggs Institute (JBI) appraisal tool.

Results

This review identified six studies and 114 children with SCD, including 57 boys (50%) and 57 girls (50%). The majority of SCD types experienced were HbSS (86.84%), HbS-B0 Thal (7.01%), HbSC (5.27%), and the HbSS Arab-Indian haplotype (0.88%). Bone disease problems that often arise in children with SCD include Avascular Necrosis (AVN) (78.08%), Osteonecrosis of the Femoral Head (ONFH) (18.42%), and other bone problems (3.50%). Meanwhile, four types of intervention findings were used in managing bone disease among children with SCD: 1). Surgical procedures 53 (41.09%) included total hip arthroplasty (THA), Osteotomy, and Multiple epiphyseal drilling with Autologous Bone Marrow Implantation (AMBI); 2). Invasive procedures 67 (51.93%) included intravenous bisphosphonates, hydroxyurea (HU), and core decompression (CD) with bone marrow aspirate concentrate injection: 3). Oral pharmacological or Vitamin D3 (cholecalciferol) 4 (3.10%); 4). Non-pharmacology or physical therapy 5 (3.88%).

Conclusion

Our findings highlight that surgical, invasive, pharmacological, and physical therapy interventions positively impact increasing bone mineral density (BMD) and functional improvement of bone disease among children with SCD. The interventions provided excellent functional outcomes with minimal complications and no life-threatening side effects.

Provider Attitudes, Preferences, and Practices Regarding Sexual and Reproductive Health for Adolescents and Young Adults With Sickle Cell Disease

PURPOSE

With improvements in life expectancy, adolescents and young adults (AYAs) with sickle cell disease (SCD) increasingly face sexual and reproductive health (SRH) concerns. As subspecialists often serve as primary care providers for those with chronic disease, this study examines pediatric SCD providers' practices and attitudes related to SRH of AYA women with SCD.

METHODS

We developed an adapted survey to identify SCD provider attitudes and practices in addressing menses, sexual activity, contraception, and pregnancy for their female patients. We electronically distributed this survey to the American Society of Pediatric Hematology/Oncology SCD interest group. We used descriptive statistics to analyze results.

RESULTS

A total of 78 pediatric SCD providers completed the survey. A majority (95%) rated SRH discussions as moderately important or higher, with 89% agreeing this care should be standardized. Most respondents reported discussing SRH, such as menses (78%), teratogenic medications (61%), and contraception (90%), with their female patients with SCD at least annually. Although most refer AYAs with SCD for birth control (83%), 39% endorsed a preferred method, with 33% of these favoring levonorgestrel intrauterine devices in this population and 40% injectable contraception. Approximately half of respondents (57%) reported that the use of combined hormonal contraceptives was unacceptable despite published guidelines that support potential benefits outweighing theoretical risk in AYAs with SCD.

CONCLUSIONS

The range of SRH conversations and contraceptive recommendations for AYAs from pediatric SCD providers is broad. SCD providers and AYAs with SCD would benefit from improved evidence and educational resources related to contraception as well as coordinated SRH counseling.
