Successful stabilisation of nephropathy in a patient with POEMS (polyneuropathy, organomegaly, endocrinopathy, M-band, skin changes) syndrome on treatment with mycophenolate and steroids: a case report

INTRODUCTION: Renal involvement in POEMS (polyneuropathy, organomegaly, endocrinopathy, M-band, skin changes) syndrome is considered to be an under-diagnosed phenomenon with no clear treatment path. The limited literature suggests steroids to be the drug of choice, although improvements are limited and usually reverse on withdrawal of the drug. CASE PRESENTATION: A 52-year-old Caucasian woman presenting with features consistent with POEMS syndrome developed progressive renal impairment with proteinuria. Renal biopsy revealed a membranoproliferative glomerulonephritis. She was treated with relatively low dose oral mycophenolate mofetil and prednisolone which stabilised her nephropathy and neuropathy. CONCLUSION: We describe an alternative therapeutic option in patients with this serious but poorly understood condition.
