INTRODUCTION: Acute kidney injury (AKI) is one of the severe complications in dengue hemorrhagic fever, usually occurred in shock. We report an interesting case of AKI in a hemodynamically stable dengue hemorrhagic fever patient. CASE PRESENTATION: An 18-year-old male dengue fever patient referred to our institution in his day eight of illness due to three days of decreased urine output. He was hemodynamically stable with thrombocytopenia, increase in creatinine, positive for Anti dengue IgM, proteinuria, and hematuria. Ultrasound examination showed ascites. He was diagnosed with AKI stage III related to dengue hemorrhagic fever and underwent hemodialysis. A total of four series of hemodialysis and furosemide drip were performed during 12 days of admission and he was finally improved. CONCLUSION: Renal injury might occur in hemodynamically stable dengue hemorrhagic patients. It is a reversible condition; hence, appropriate treatment and close monitoring result in good outcomes

Objectives To express and characterize NS1 of Indonesian-specific DENV2 virus in Pichia pastoris (P. pastoris). Methods A codon optimized synthetic gene derived from the DENV-2 NS1 amino acid sequences was synthesized commercially and inserted into the P. pastoris pPICZαA expression vector. The recombinant DENV-2 NS1 protein was purified by Ni-NTA affinity chromatography, and its antigenicity was tested. Results The recombinant DENV-2 NS1 protein was secreted as a protein with a molecular weight of ∼45 kDa, and the optimal expression condition was achieved by induction with 2% (v/v) methanol for 72 h. The purified recombinant DENV-2 NS1 protein was able to interact with a monoclonal antibody of NS1 in a commercial rapid test. Conclusions The resulting recombinant DENV-2 NS1 protein produced in P. pastoris KM71 is a potential candidate for use in the development of a dengue diagnostic kit and vaccine.
