ABSTRACT

ABSTRACT Rapidly progressive glomerulonephritis (RPGN) is a renal disease with an extensive differential diagnosis. This paper reports the case of a 55-year-old female patient diagnosed with Hansen's disease with acute progressive renal impairment after developing lower limb pyoderma. The association between Hansen's and kidney disease has been well documented, with glomerulonephritis (GN) ranked as the most common form of renal involvement. Post-infectious glomerulonephritis (PIGN) in adults has been associated with a number of pathogens occurring in diverse sites. The patient described in this case report had RPGN and biopsy findings suggestive of PIGN with C3 and IgA detected on immunofluorescence and kidney injury secondary to recent infection by Staphylococcus, a well-documented manifestation of renal impairment in patients with Hansen's disease.


RESUMO A Glomerulonefrite Rapidamente Progressiva (GNRP) é um padrão de doença renal com amplo diagnóstico diferencial. O caso reporta uma paciente de 55 anos com deterioração aguda e progressiva da função renal após quadro de piodermite em membro inferior com diagnóstico concomitante de hanseníase. Associação da hanseníase com doença renal é bem descrita, sendo a GN a forma de acometimento renal mais comum. As glomerulonefrites pós-infecciosas (GNPIs) em adultos ocorrem devido a um grande número de patógenos, nos mais diversos sítios. A paciente do caso relatado apresentava quadro de GNRP e achados de biópsia que sugerem GNPI com marcação de C3 e IgA na imunofluorescência, sugestiva de lesão renal secundária a infecção recente por Staphylococcus, uma manifestação bem descrita de doença renal em pacientes com hanseníase.
