Cyproheptadine enhances weight gain in children with FTT, modulating Nesfatin-1 and NUCB2.

Cyproheptadine enhances weight gain and modulates appetite-regulating peptides in children with failure to thrive and food allergies.

Background

The study addresses Failure to Thrive (FTT) in children, particularly those with co-occurring food allergies, a complex condition characterized by inadequate weight gain. Current management often relies on dietary interventions, but pharmacotherapeutic options are limited, especially when dietary restrictions are necessary due to allergies. Cyproheptadine hydrochloride (CH), an antihistamine known for its appetite-stimulating properties, presents a potential therapeutic avenue. This research explores CH's impact on growth parameters and the modulation of appetite-regulating peptides in this vulnerable pediatric population.

Study Design

This non-randomized, real-world study enrolled children aged 1-3 years diagnosed with FTT and food allergy. Participants were allocated to either a treatment group (T-group, n = 25) or a control group (NT-group, n = 19). The T-group received cyproheptadine at 0.15 mg/kg twice daily for 12 weeks. Primary outcomes included anthropometric indices such as body weight, WAZ (weight-for-age Z-score), WLZ (weight-for-length Z-score), BMI (body mass index), height, and LAZ (length-for-age Z-score). Secondary outcomes assessed clinical symptom scores and serum levels of the appetite-regulating peptides Nesfatin-1 and NUCB2.

Results

After 12 weeks of treatment, the T-group demonstrated significantly greater improvements in body weight (10.32 ± 0.28 kg vs. 9.05 ± 0.23 kg, P = 0.002), WAZ (P < 0.001), WLZ (P < 0.001), and BMI (P = 0.001) when compared to the NT-group. No significant differences were observed in height or LAZ between the groups. Within the T-group, all weight-based indices (body weight, WAZ, WLZ, BMI) showed significant improvements from baseline to week 12 (P < 0.001 for all). > Cyproheptadine treatment was also associated with significant reductions in serum Nesfatin-1 (P = 0.000) and NUCB2 (P = 0.043) levels. At baseline, reduced food intake and sleep disturbances were negatively correlated with WAZ and LAZ, respectively.

Key Findings

  • Cyproheptadine treatment significantly increased body weight (10.32 ± 0.28 kg vs. 9.05 ± 0.23 kg, P = 0.002) in the T-group.
  • WAZ, WLZ, and BMI significantly improved in the cyproheptadine group (P < 0.001 for WAZ/WLZ, P = 0.001 for BMI).
  • Serum Nesfatin-1 levels significantly decreased with cyproheptadine treatment (P = 0.000).
  • Serum NUCB2 levels significantly decreased with cyproheptadine treatment (P = 0.043).
  • No significant differences were observed in height or LAZ between the groups.

Why It Matters

Cyproheptadine offers a promising pharmacotherapeutic option for young children with FTT and food allergies, a population often facing limited treatment choices. This study suggests that a protocol of 0.15 mg/kg twice daily could effectively enhance weight gain and improve crucial growth parameters. The observed downregulation of anorexigenic peptides Nesfatin-1 and NUCB2 provides a mechanistic insight, indicating that cyproheptadine not only stimulates appetite but also favorably modulates underlying hormonal signals. This could lead to more targeted and effective interventions for FTT, potentially improving long-term health outcomes for these vulnerable children. Further research in larger, randomized trials is warranted to confirm these findings and establish broader clinical applicability.
