Summary

What Researchers Did

Doctors describe the case of a 35-year-old woman with severe pernicious anaemia who could not receive a blood transfusion for religious reasons, and who received hyperbaric oxygen therapy (HBO) along with vitamin B treatment.

What They Found

This is a single case report, and the abstract excerpt provided does not report an outcome or result for this patient. It states that she presented with fatigue, shortness of breath (dyspnoea), and a haemoglobin level of 26 g/L, and that she was diagnosed with pernicious anaemia. HBO is described as being used as part of her care, but no information on how she responded to treatment is included in this excerpt.

Canadian Relevance

No direct Canadian connection identified.

Study Limitations

This is a single case report with no comparison group, and the outcome of treatment is not included in the available abstract, so no conclusions about effectiveness can be drawn.
