Two cases of self-limiting nephropathies secondary to dengue haemorrhagic fever

We report two cases of dengue haemorrhagic fever which developed self-limiting gross nephrotic-range proteinuria. One patient was a 32-year-old Bangladeshi and the other a 42-year-old Chinese national. Both patients did not have manifestations of renal damage, such as increase in serum creatinine, haematuria or urinary casts. Gross nephrotic-range proteinuria, which was self-limiting due to dengue haemorrhagic fever, has not been previously reported in Singapore. We postulate that this nephrotic-range proteinuria is a manifestation of increased glomerular leakage of protein, due to glomerulonephritis associated with dengue haemorrhagic fever.
