Characterization of thrombocytopenia, leukopenia and increased hematocrit in the evolution and severity of patients with dengue diagnosis

Abstract

Dengue virus (DENV) has haunted our planet for more than three centuries. The Aedes aegypti bite causes DENV. Clinical and laboratory diagnosis are important for the management of dengue. Objective: to characterize the presence of plaquetopenia, leukopenia and increased hematocrit with the evolution and severity of patients with Dengue, Hospital Univalle. Material and methods: retrospective, longitudinal and analytical study, 2017 to 2020. Results: 235 patients were identified, 83% in 2020; 65% between 19 to 45 years old; the male sex with 54%. 80% come from Cercado-Cochabamba, of these more than 95% from the southern area. The test with the detection of the NS1Ag protein (AccuBio Tech Co, Ltd.) was used in 71%; 56% were hospitalized; more than 50% presented symptoms between the 2nd and 5th day; Within the dengue classification, 75% belonged to dengue without warning signs (p = <0,01). Fever (p = 0,001), associated with symptoms of alarm such as abdominal pain, persistent vomiting, and bleeding (p = <0,05) were frequent. Leukopenia <5 000 / mm3 was common in women with warning signs, in contrast to men; thrombocytopenia in patients with warning signs and in men; hematocrit> 45% in men and represented more than 5 days of hospitalization (p = 0,023). Conclusions: Plaquetopenia, leukopenia and increased hematocrit are biomarkers of clinical severity, hospital stay, associated with an early diagnosis, using the symptoms and rapid tests available; finally, consider the presence of autochthonous patients from the southern area of Cochabamba, Cercado.
