    This study found that individuals with pellagra experience significantly reduced post-ischaemic paraesthesia responses. This reduction was more pronounced in pellagrins with peripheral neuropathy.

    Area of Science:

    • Neurology
    • Nutritional Science
    • Clinical Medicine

    Background:

    • Pellagra, a deficiency disease, is associated with neurological complications.
    • Peripheral neuropathy is a known manifestation of severe pellagra.
    • Paraesthesia, or abnormal sensations, can occur following ischemia.

    Purpose of the Study:

    • To quantitatively assess post-ischaemic paraesthesia in pellagrins compared to healthy controls.
    • To investigate the impact of peripheral neuropathy on paraesthesia responses in pellagra patients.

    Main Methods:

    • A quantitative assessment of post-ischaemic paraesthesia was performed.
    • Fifty individuals with pellagra and 20 healthy identical controls participated.
    • Comparison of paraesthetic response between groups and subgroups.

    Main Results:

    • A highly significant diminution of the paraesthetic response was observed in pellagrins.
    • Pellagrins with peripheral neuropathy exhibited a more marked depression of paraesthesia.
    • No consistent relationship was found between the severity of peripheral neuropathy and the degree of paraesthetic response depression.

    Conclusions:

    • Pellagra significantly impairs the sensory response to post-ischaemic stimuli.
    • Peripheral neuropathy in pellagra exacerbates the reduction in paraesthetic responses.
    • Further research may elucidate the specific mechanisms underlying sensory pathway dysfunction in pellagra.
