Objective: To describe the prognostic and clinical profile of hospitalized patients with chikungunya virus (CHIKV) infection focusing on renal outcomes. Methods: This is a cross-sectional study including all patients with confirmed chikungunya fever (CHIKF) admitted to 3 different high-complexity hospitals in Fortaleza, Brazil between January 2016 and June 2017. Data analysis was carried out to evaluate correlation between clinical profile and outcomes. Results: Fifty-five patients were included, with a median age of 77 (IQR=21) years, and 23 (41.82%) were male. Twenty-five patients (45.45%, 25/55) developed acute kidney injury (AKI), and 15 (60.00%, 15/25) were classified as KDIGO 1, 1 (4.00%) as KDIGO 2, and 9 (36.00%) as KDIGO 3. The overall mortality was 34.54% whilst AKI-related mortality was 64.00% (16/25). Both AKI and encephalitis were associated with higher mortality. Patients who died were significantly older [82 (IQR=12) years vs. 70 (IQR= 28.75) years, P<0.001)]. In the multivariate analysis, abdominal pain was associated with an increased risk of severe AKI (OR=5.33, 95% CI=1.11-25.64, P=0.037) and AKI was an independent risk factor of death (OR=12.06, 95% CI=2.55-57.15, P=0.002). Recovery of renal function was similar among the different age groups. Conclusions: AKI is present in half of the study population and is an independent risk factor of death. Thus, renal function should be carefully monitored in hospitalized patients with CHIKV infection.

Leptospirosis is a bacterial disease disseminated through the centuries in the whole world which causes symptoms that go from self-limited diseases to hemorrhagic manifestations and organ failure, including acute kidney injury (AKI), composing the severe disease known as the Weil's syndrome. Mortality rates varies according to the clinical presentation and usually increases when kidney injury is present, and is even higher in the setting of pulmonary hemorrhage. There are recent advances in the search for novel biomarkers of renal involvement and early detection of AKI in leptospirosis, as well as in its pathophysiology. We review in this article the clinical aspects of leptospirosis-associated AKI and the perspectives for future research.
