RESUMO Objetivo: Avaliar como a funcionalidade e a disfunção orgânica aguda influenciam a mortalidade hospitalar de pacientes oncológicos admitidos com suspeita de sepse. Métodos: Os dados foram obtidos de uma coorte retrospectiva de pacientes oncológicos com suspeita de infecção admitidos em uma unidade de terapia intensiva. Estes receberam antibióticos por via parenteral e tiveram suas culturas coletadas. Utilizamos uma regressão logística, para avaliar a mortalidade hospitalar como desfecho, Sequential Organ Failure Assessment e Eastern Cooperative Oncology Group como preditores, além de suas interações. Resultados: Dentre os 450 pacientes incluídos, 265 (58,9%) morreram no hospital. Para os pacientes admitidos na unidade de terapia intensiva com Sequential Organ Failure Assessment baixo (≤ 6), o comprometimento da funcionalidade influenciou a mortalidade hospitalar, que foi de 32% entre os pacientes sem comprometimento ou com comprometimento mínimo da funcionalidade e 52% entre os pacientes com comprometimento moderado e grave (p < 0,01). Nos pacientes com Sequential Organ Failure Assessment elevado (> 6), a funcionalidade não influenciou a mortalidade hospitalar (73% entre os pacientes sem comprometimento ou com comprometimento mínimo, e 84% entre os pacientes com comprometimento moderado e grave; p = 0,1). Conclusão: O comprometimento da funcionalidade parece influenciar a mortalidade hospitalar de pacientes oncológicos com suspeita de sepse sem disfunções orgânicas agudas ou que apresentem disfunções leves no momento da admissão na unidade de terapia intensiva.

ABSTRACT Objective: To evaluate how performance status impairment and acute organ dysfunction influence hospital mortality in critically ill patients with cancer who were admitted with suspected sepsis. Methods: Data were obtained from a retrospective cohort of patients, admitted to an intensive care unit, with cancer and with a suspected infection who received parenteral antibiotics and underwent the collection of bodily fluid samples. We used logistic regression with hospital mortality as the outcome and the Sequential Organ Failure Assessment score, Eastern Cooperative Oncology Group status, and their interactions as predictors. Results: Of 450 patients included, 265 (58.9%) died in the hospital. For patients admitted to the intensive care unit with lower Sequential Organ Failure Assessment (≤ 6), performance status impairment influenced the in-hospital mortality, which was 32% among those with no and minor performance status impairment and 52% among those with moderate and severe performance status impairment, p < 0.01. However, for those with higher Sequential Organ Failure Assessment (> 6), performance status impairment did not influence the in-hospital mortality (73% among those with no and minor impairment and 84% among those with moderate and severe impairment; p = 0.1). Conclusion: Performance status impairment seems to influence hospital mortality in critically ill cancer patients with suspected sepsis when they have less severe acute organ dysfunction at the time of intensive care unit admission.

ABSTRACT Objective: We evaluated the kinetics of cytokines belonging to the T helper1 (Th1), Th2, and Th17 profiles in septic patients, and their correlations with organ dysfunction and hospital mortality. Methods: This was a prospective observational study in a cohort of septic patients admitted to the intensive care units (ICU) of three Brazilian general hospitals. A total of 104 septic patients and 53 health volunteers (controls) were included. Plasma samples were collected within the first 48 h of organ dysfunction or septic shock (0D), after seven (D7) and 14 days (D14) of follow-up. The following cytokines were measured by flow cytometry: Interleukin-1β (IL-1β), IL-2, IL-6, IL-8, IL-10, IL-12/23p40, IL-17, IL-21, tumor necrosis factor-α (TNF-α), granulocyte-macrophage colony stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF). Results: IL-6, IL-8, G-CSF and IL-10 concentrations were higher in septic patients than in controls (p < 0.001), while IL-12/23p40 presented higher levels in the controls (p = 0.003). IL-6, IL-8 and IL-17 correlated with Sequential [Sepsis-related] Organ Failure Assessment (SOFA) D0, D1 and D3 (except for IL-6 at D0). IL-8 was associated with renal and cardiovascular dysfunction. In a mixed model analysis, IL-10 estimated means were lower in survivors than in deceased (p = 0.014), while IL-21 had an estimated mean of 195.8 pg/mL for survivors and 98.5 for deceased (p = 0.03). Cytokines were grouped in four factors according to their kinetics over the three dosages (D0, D7, D14). Group 1 encompassed IL-6, IL-8, IL-10, IL-1β, and G-CSF while Group 3 encompassed IL-17 and IL-12/23p40. Both correlated with SOFA (D0) (p = 0.039 and p = 0.003, respectively). IL-21 (Group 4) was higher in those who survived. IL-2, TNF-α and GM-CSF (Group 2) showed no correlation with outcomes. Conclusion: Inflammatory and anti-inflammatory cytokines shared co-variance in septic patients and were related to organ dysfunctions and hospital mortality.
