In this investigation, we discovered that dengue patients with diabetes had lower serum albumin levels (0.69 ± 0.07) g/dl and platelet counts (49.758 ± 3.349) × 103 cells/μL than those without diabetes having serum albumin levels (1.24 ± 0.14) g/dl and platelet counts (58.36 ± 1.634) × 103 cells/μL. This evidence concerns the gene ALB and diabetes mellitus.
