Administration classification

Other forms

Study result signal

Indeterminate for molecular hydrogen.

Outcome type

Clinical and biomarker outcomes in a single patient.

Reported in the source

Methods at a glance

Population or model

One pediatric patient with anti-NMDA receptor encephalitis receiving intensive immunotherapy.

Sample

1 patient.

Duration

Follow-up over the treatment timeline reported in the article.

Intervention

One oral hydrogen-generating capsule daily as adjunctive therapy.

Hydrogen form

Hydrogen generated after capsule ingestion; not Brown's gas.

H₂ specification

Systemic hydrogen exposure was not directly measured.

H₂ flow

Not applicable — oral capsule.

O₂ delivered with H₂

No oxygen was co-delivered.

Comparator

No control; longitudinal clinical course.

Reported, not endorsed

Outcomes and reported result

Outcomes measured

Neurologic symptoms, clinical course and immune phenotyping.

Reported result

The report describes clinical and immunologic changes after hydrogen was added to rituximab, intravenous immunoglobulin and other care.

Results-extraction completeness

The full case report, treatment timeline, clinical observations and immune measurements were checked.

A reported association, difference or mechanism is not automatically a clinical benefit. Null findings, outcome type, study design and precision all matter.

Interpretation limits

Cautions and applicability

Design and reporting cautions

Concurrent intensive treatment and natural recovery make causal attribution to hydrogen impossible.

Applies directly to

This individual case only.

Preliminary appraisal framework

JBI Case Report Checklist — preliminary

Preliminary risk-of-bias status

Serious concerns

Appraisal rationale

No comparator and major time-varying confounding from immunotherapy and supportive care.

Appraisal domains

Single selected case · Co-interventions were present · Follow-up described in the report · Several outcomes were clinician- or patient-reported · No prespecified analysis plan

No single-study GRADE certainty rating is assigned. Certainty is assessed by important outcome across a complete eligible evidence set, not by attaching a final grade to one source.
