Independent of severity at the time of ICU admission, isolation of penicillin-nonsusceptible strains and a delay in antibiotic treatment following admission were predictors of mortality among patients with pneumococcal meningitis.
The number of HIV-infected patients admitted to the ICU remained high in the HAART era. Underutilization of HAART and limited access to health care are possible explanations. The ICU mortality has remained unchanged, but 3-month mortality has decreased.
Thrombotic microangiopathies with severe organ dysfunctions leading to hospitalization in the intensive care unit are associated with high mortality. Neurologic impairment appears to be the main adverse prognostic factor correlated to mortality, and the study confirms the importance of plasma exchange in the treatment of high-risk patients.
We have undertaken this retrospective study to determine factors associated with in-hospital mortality and morbidity in 80 adult patients with severe Streptococcus pneumoniae meningitis. Clinical characteristics at admission of patients infected with susceptible (n = 54) and nonsusceptible (n = 17) strains to penicillin G were similar: age: 51 +/- 19 versus 58 +/- 15 yr (p = 0.16); Simplified Acute Severity Score (SAPS II): 39 +/- 14 versus 41 +/- 11 (p = 0.68); and Glasgow Coma Score: 8 +/- 3 versus 9.5 +/- 3 (p = 0.21), respectively. In-hospital mortality was 25% (20/80), with one death among the 17 patients (6%) infected with a nonsusceptible strain (p = 0.03). High-dose dexamethasone was used in 22 cases. By multivariate analysis, three factors were independently associated with death: platelet count < 100 G/L (adjusted odds ratio [aOR] = 32.7; 95% CI = 3.2 to 332.5; p = 0.0032), arterial pH > 7.47 (aOR = 33.1; 95% CI = 3.4 to 319.7; p = 0.0025), and mechanical ventilation (aOR = 48.8; 95% CI = 2.6 to 901.5; p = 0.009). When adjusting for the identified prognostic factors, corticosteroids significantly reduced the risk of death (aOR = 0.069; 95% CI = 0.005 to 0.9; p = 0.048). Only SAPS II was predictive of adverse outcome (death or neurologic deficit). We conclude that in intubated patients with S. pneumoniae meningitis, hyperventilation should be used with caution. Nonsusceptibility to penicillin G is not associated with a worse outcome. High-dose corticosteroids may be beneficial in the most severely ill patients.
These results suggest that both heated humidifiers and heat and moisture exchanger filters can be used with no significant impact on the incidence of ventilator-associated pneumonia and that other criteria may justify their choice.
We report three cases of severe thrombocytopenia during COVID-19 infection associated with either cutaneous purpura or mucosal bleeding. The initial investigations ruled out other causes of thrombocytopenia. Two of the patients were treated with intravenous immunoglobulins and eltrombopag, while the third recovered spontaneously. A good clinical and biological response was achieved in all patients leading to hospital discharge.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
