Biotin treatment for eczema effectiveness
Biotinidase deficiency characterized by skin and hair findings.
Direct relevance to biotin usage
We explored a unique case involving a girl diagnosed with biotinidase deficiency, a rare inherited metabolic condition that can lead to notable skin and hair issues. The report highlighted her struggles with intractable dermatitis, yellow hair, and alopecia—symptoms that pointed to the underlying deficiency.

Biotin, a vital nutrient, was administered at a dose of 20 mg per day as a replacement therapy. Within one month, we observed a substantial improvement in her dermatitis, and by the three-month mark, her hair color had returned to near normal. The significant change in her condition illustrates how effective biotin can be for individuals suffering from both biotinidase deficiency and associated eczema-like symptoms.

This case serves as a reminder for healthcare providers, especially dermatologists, to consider biotinidase deficiency as a potential factor when treating similar conditions in children. By recognizing the importance of biotin, we can help improve health outcomes for those experiencing dermatological challenges tied to this rare disorder.

Biotin supplementation improves eczema
Normalization of low biotinidase activity in a child with biotin deficiency after biotin supplementation.
Study highlights biotin's efficacy
We observed the case of a Japanese boy who suffered from a severe skin rash caused by biotin deficiency. This child had unique health challenges, including an intracranial malformation, and was fed through a tube using a single formula for more than a year. This feeding method led to a deficiency in biotin, an essential nutrient known for its role in maintaining skin health and other bodily functions.

Upon analysis, we found the boy had low biotinidase activity, which is important for processing biotin in the body. The good news is that after introducing biotin supplementation into his routine, not only did his skin rash improve significantly, but his biotinidase activity also returned to normal levels.

This case suggests that biotin plays a key role in regulating the production of biotinidase, highlighting its potential benefits in treating conditions like eczema, especially when linked to a deficiency. It's a promising finding, although we must acknowledge that this is a report based on a single patient’s experience.

Investigated biotin for eczema
Screening of carnitine and biotin deficiencies on tandem mass spectrometry.
Biotin's effect on eczema
We explored the potential benefits of biotin in treating eczema, particularly in pediatric patients. In the context of a study involving 42 children, we assessed nutritional deficiencies that might be affecting their skin health, especially considering some were on enteral feeding.

Among the findings, we discovered one patient with therapy-resistant eczema responded positively to treatment with additional biotin. Alongside this treatment, they also switched to a non-hydrolyzed formula. However, since biotin was administered in combination with other interventions, we cannot conclude that biotin alone was responsible for the improvement.

Overall, while the results suggest that biotin may have a role in addressing eczema in specific cases, the effects are not isolated. Further research would be needed to fully understand the impact of biotin on eczema management.

Energy and eczema relief
This helped my eczema! I initially purchased this for energy, but I began to notice that my eczema became much more manageable. I didn’t expect this outcome. However, when I stopped taking it, I found that my eczema would flare up easily again. Taking biotin (one pill a day) seems to enhance the effectiveness of my eczema cream. I am uncertain if it made a notable difference in my energy levels.

Effective against rashes
I often suffer from allergies that cause rashes and eczema. Since starting biotin, I've noticed less frequent flare-ups and quicker healing. My reliance on strong ointments has decreased, so I intend to keep taking it.

Eczema healing noted
After frequently using bleach and gel nails, I began taking biotin for stronger hair and nails. While I’m unsure about those results, my long-standing hand eczema has beautifully healed since I started taking it. I only wish I had started sooner!

HLCS deficiency improves with biotin
Holocarboxylase Synthetase Deficiency: Clinical, Biochemical and Molecular Findings in Five Malaysian Patients Including a Newborn Presenting as Collodion Baby.
Translational importance for treatment
We examined a rare condition called holocarboxylase synthetase (HLCS) deficiency, which affects biotin metabolism in patients. Our study focused on five patients diagnosed between 2015 and 2024.

Each patient presented with skin rashes and severe symptoms, including respiratory distress and seizures. Remarkably, four out of five patients showed improvement with biotin therapy, receiving daily doses of 10-30 mg that helped maintain their metabolic health.

This study highlights the importance of early detection and intervention with biotin to prevent serious complications, making a strong case for screening specific gene mutations in affected individuals.

Biotin improves overall health outcomes
[Diagnosis and treatment of biotinidase deficiency-clinical study of six patients].
Moderate impact on eczema noted
We explored how biotin treatment affects patients with biotinidase deficiency, focusing on their clinical features, which include skin conditions like eczema. In our study, six patients ranging from only a few months old to 14 years displayed a variety of neurological and dermatological symptoms.

Among these, Case 2 had eczema that started at 7 months old, and Case 6 also dealt with eczema and additional skin issues such as alopecia. Biotin supplements were given to most of the patients, and we saw that they made notable improvements in their overall health.

While biotin appeared beneficial in addressing general symptoms of biotinidase deficiency, particularly regarding nervous system function, the specific impact on eczema was less clear and may not have been as straightforward. Our observation suggests that early diagnosis and biotin supplementation play significant roles in improving outcomes for these patients overall.
