To assess the association between type 2 diabetes mellitus (DM2) and the severity of dengue disease in adults treated at hospitals in Piura, Peru. Materials and Methods: We conducted a matched case-control study (1:2:2) by month from January to December 2023. Cases were patients diagnosed with severe dengue, while controls consisted of patients diagnosed with dengue with warning signs (controls A) and dengue without warning signs (controls B). The exposure variable was type 2 diabetes mellitus (DM2). We measured demographic, clinical, and laboratory variables. We used tests for significance of the null hypothesis (PSHN) for paired samples and general ordinal logistic regression models with fixed effects per month (FEOLOGIT) with 1000 clones to estimate odds ratios (OR) with 95% confidence intervals (CI) both crude and adjusted for epidemiological criteria, and from there we estimated marginal probabilities for dengue with warning signs and severe dengue. Additionally, as an exploratory approach and by stage, we applied sequential logistic transition models with fixed effects per month (SEQLOGIT) and generalized ordinal continuous ratio models (GNCRM) to estimate OR 95% CI in both cases with non-parametric bootstrap with corrected and accelerated bias of 1000 repetitions. Results: We included 82 cases, 164 controls A, and 164 controls B. The frequency of DM2 was 25.6% in patients with severe dengue, 14% in patients with dengue with warning signs (controls A), and 7.3% in patients with dengue without warning signs (controls B) (p<0.001). Additionally, in the PSHN, we found statistical evidence of association between severity levels and male sex (p=0.006), ederly (p<0.001), come from another district of Piura, other provinces of Piura and the district of Castilla (p=0.001), hypertension (p<0.001), and chronic disease (p<0.001). In the FEOLOGITs, we observed association at crude level (ORc 2.84; 95% CI 1.41- 5.71; p=0.003) and adjusted level (ORa 2.67; 95% CI 1.56-4.58; p<0.001). In crude marginal estimates, patients with DM2 had a 8.35% probability (95% CI 2.7%-13.93%; p=0.003) of developing dengue with warning signs and 16.7% (95% CI 5.5%-27.87%; p=0.003) for severe dengue; these probabilities remained in adjusted marginal estimates: 7.87% (95% CI 3.6%- 12.17%; p<0.001) and 15.75% (95% CI 7.1%-24.35%; p<0.001); respectively. In the SEQLOGIT models we observed that DM2 increases the transition from dengue without warning signs to dengue with warning signs and severe dengue (ORc: 2.83; 95% CI: 1.41-5.40; p=0.002) and from dengue with warning signs to severe dengue (ORc:2.31; 95% CI 1.18-4.29; p=0.010). At an exploratory level, in the GENCRM models we show that patients with DM2 7 have an increased odds of progressing to a higher severity stage compared to those without DM2 both in the models with compliance with proportionality (ORa 2.39; 1.23-4 .63; p=0.010), with variation due to exposure (ORa 2.55; 1.09-5.98; p=0.030) and with free variation (ORa 2.55; 1.05-5.19; p =0.037). In the SEQLOGIT models we observed that DM2 increases the probability of transition from dengue without warning signs to dengue with warning signs and severe dengue (aOR: 2.65; 95% CI: 1.23-6.45; p=0.009 ) and from dengue with warning signs to severe dengue (aOR:2.11; 95% CI 1.07-4.17; p=0.032). Conclusion: We demonstrated an association between DM2 and dengue severity independent of measured demographic and clinical variables. Patients with DM2 have higher odds and probability of developing dengue with warning signs and severe dengue compared to those without diabetes mellitus. Longitudinal studies are required to confirm these findings.
