Researchers tested whether vitamin A supplements could help children with sepsis (a dangerous blood infection) recover faster. They studied 156 children in the hospital, giving half vitamin A and half a fake pill. While the supplements didn’t reduce how long kids stayed in the ICU or lower death rates, they did seem to help reduce some signs of inflammation in the body. The supplements were safe with no side effects, but more research is needed to understand if vitamin A truly helps children fight serious infections.

The Quick Take

  • What they studied: Whether giving vitamin A supplements to children with sepsis (a life-threatening infection) would help them recover faster and stay in the hospital for less time
  • Who participated: 156 children diagnosed with sepsis who were treated in a hospital ICU over nearly 4 years, with 72 getting vitamin A and 84 getting a placebo
  • Key finding: Vitamin A supplements didn’t reduce ICU stay time (14 vs 16.5 days) or death rates, but they did appear to lower some inflammation markers in the blood
  • What it means for you: If your child has sepsis, vitamin A supplements appear safe but won’t necessarily speed recovery - focus on following your doctor’s main treatment plan

The Research Details

This was a randomized controlled trial, which is considered the gold standard for testing treatments. Researchers randomly assigned children with sepsis to receive either vitamin A supplements or a placebo (fake pill that looks identical). The study was single-blind, meaning the children and families didn’t know which treatment they received, but the doctors did. This design helps ensure that any differences between groups are due to the treatment, not other factors.

The researchers chose this approach because their earlier work showed that children with sepsis often have low vitamin A levels, and sicker children tend to have even lower levels. By testing vitamin A supplements in a controlled way, they could determine if boosting these levels actually helps children recover.

This study has several strengths: it was conducted over nearly 4 years with a reasonable number of participants, used proper randomization, and was registered with clinical trials databases. However, it was done at only one hospital, which may limit how broadly the results apply to other settings.

What the Results Show

The main goal was to see if vitamin A supplements would reduce how long children stayed in the ICU. Unfortunately, there was no significant difference - children getting vitamin A stayed an average of 14 days compared to 16.5 days for those getting placebo. The study also found no differences in total hospital stay, death rates after 28 days, time on breathing machines, or antibiotic use. These results suggest that vitamin A supplements don’t provide the major recovery benefits researchers hoped for.

While the main outcomes were disappointing, the researchers found some interesting changes in blood tests. Children getting vitamin A showed improvements in lactate levels (a marker of how well cells are using oxygen) and had better trends in albumin levels (a protein that indicates nutritional status). They also had lower white blood cell counts and bigger drops in PCT levels (both signs of reduced inflammation).

This study builds on the same research team’s earlier work showing that children with sepsis often have vitamin A deficiency. However, this is one of the first controlled trials to actually test whether supplementing vitamin A helps these children recover, making it an important addition to the limited research in this area.

The study was conducted at only one hospital, which may limit how well the results apply elsewhere. The researchers also noted that they didn’t find the large differences they expected, which might mean they needed more participants to detect smaller but still meaningful effects. Additionally, the study focused on short-term outcomes and didn’t follow children long-term.

The Bottom Line

Based on this research, vitamin A supplements appear safe for children with sepsis but shouldn’t be expected to dramatically speed recovery or reduce ICU stays. Parents should focus on following their medical team’s primary treatment recommendations rather than relying on vitamin A as a major intervention.

Parents of children with sepsis, pediatric ICU doctors, and healthcare providers treating serious infections in children should be aware of these findings. However, treatment decisions should always be made with the medical team, not based on this research alone.

The study measured effects over days to weeks during hospitalization. Any potential benefits from vitamin A appeared within the first few days, but the major outcomes like ICU length of stay weren’t significantly improved.

Want to Apply This Research?

  • Track your child’s vitamin A intake through foods like carrots, sweet potatoes, and leafy greens, aiming for age-appropriate daily recommended amounts
  • Focus on maintaining good vitamin A status through a balanced diet rich in colorful fruits and vegetables rather than relying on supplements for serious illness prevention
  • Log your family’s intake of vitamin A-rich foods weekly and discuss any concerns about nutritional status with your pediatrician during regular check-ups
