Prevalence, patterns, and factors associated with bleeding tendencies in dengue

Abstract: Introduction: The pattern of bleeding tendencies in dengue and its corellation with platelet count and other factors requires clarification. Methodology: A retrospective study on bleeding tendencies in adults with dengue and platelet counts of less than 100,000 per mm 3 was conducted. Factors associated with bleeding were analyzed. The study cohort were grouped as dengue with severe thrombocytopenia when platelet count was < 50,000/mm 3 and as dengue with moderate thrombocytopenia if platelet count was 50,000-… Show more

“…Peripheral immune-mediated platelet destruction also occurs via DENV binding to platelets [ 41 ]. In addition to DENV-associated imbalance between clotting and fibrinolysis systems, non-DENV-associated factors, including advanced age, sepsis-associated stress ulcers, worsening of preexisting peptic ulcers, underlying comorbidities such as cirrhosis and end-stage renal diseases, and medications (aspirin, anti-coagulants, and NSAIDs) interfering with platelet or coagulating functions, also contributed to acute GI bleeding [ 30 , 32 , 42 ]. However, this study only utilized insurance claim data, and thus GI bleeding caused by different pathologies in dengue patients could not be discriminated because detailed clinical information and laboratory findings were not available.…”

“…Algunos autores (16,18,19) han encontrado mayor incidencia de esta infección en pacientes del sexo masculino, hecho que contrasta con los resultados obtenidos en el presente estudio, en donde observamos mayor incidencia en mujeres (57% vs. 43%). Una de las manifestaciones clínicas del dengue más temida es la hemorragia, que se observa en 4% a 24% de los casos (14,20), generalmente secundaria a trombocitopenia, disfunción plaquetaria o al desarrollo de coagulación intravascular diseminada (21). En el presente estudio el 20% de los pacientes presentaron algún tipo de hemorragia; la mayoría fue sangrado leve en piel y mucosas, pero 8% presentó sangrado grave; incluso se observó que el 38% de los pacientes sin manifestaciones hemorrágicas dieron positivo en la prueba del torniquete (Rumpel-Leede).…”

“…Um estudo não randomizado com 683 pacientes com dengue, dos quais 154 apresentaram sangramentos de relevância clínica não especificada, mostrou um OR ajustado de 0,86 (IC 95%: 0,51-0,97). 70 Outros quatro estudos não randomizados, abrangendo 2.054 pacientes com dengue e 368 casos de sangramento sem correção para fatores de confusão, tiveram resultados variados: dois deles apontaram para um aumento na incidência de sangramento em pacientes tratados com AINEs, 71,72 , enquanto os outros dois não identificaram um aumento na incidência. 73,74 Nos estudos com pacientes com dengue, também há incerteza sobre o efeito dos AINEs na incidência de dor abdominal e injúria hepática.…”
