Effect of L-dopa on the seborrhoea of Parkinsonism

Abstract: Summary By studying the sebum excretion rate in patients with Parkinsonism before and during treatment with L‐dopa we have shown that L‐dopa reduces sebum excretion if seborrhoea is initially present, but has no effect on normal sebum excretion rates. The seborrhoea of Parkinsonism may be due to increased production of melanocyte‐stimulating hormone, and our finding may have therapeutic implications in Parkinsonism and breast cancer.

“…17 In addition to human immunodeficiency virus (HIV) infection, some neurological diseases such as Parkinson's disease also result in a higher incidence of SD, and Parkinson's patients in treatment with levodopa experience an improvement in SD. [26][27][28][29][30][31] The higher incidence of SD in patients with Parkinson's disease appears to be related to an increase in male sex hormone secretion and the effects of these hormones on the sebaceous glands rather than on autonomic dysfunction (dysautonomia), as was previously believed. 32 A higher prevalence of SD has also been found in cases of neuroleptic-induced Parkinsonism, in craniosynostosis, in familial amyloidotic polyneuropathy, in traumatic brain injury, traumatic spinal cord injury, cerebrovascular accidents (CVA), epilepsy and in facial nerve paralysis.…”

“…Pronounced seborrhoea due to increased size of the sebaceous glands may be the cause. J L Burton et al 14 found that 5 patients with Parkinsonism on levodopa showed dramatic response in seborrheic dermatitis after 3 weeks. Pituitary plays an important role in control of sebum secretion and L-dopa exerts its effect on sebum production by modifying pituitary secretion.…”

“…Burton et al 8 concluíram que L-dopa é eficiente em reduzir a excreção sebácea de parkinsonianos, desde que ela estivesse presente. Os resultados obtidos por Harvilli e Appenzeller 15 também são efetivos em demonstrar que L-dopa reduz a excreção sebácea em parkinsonianos.…”

“…O possível fator sebotrófico estaria sob controle inibitório 8 . A hipó-tese, aventada por Shuster et al 25, de que o aumento da excreção sebácea em parkinsonianos era conseqüente à ação do MSH, e em particular do beta-MSH, e que níveis séricos do beta-MSH estariam elevados em parkinsonianos, porém não em todos, não recebeu comprovação.…”
