High mortality in critically ill patients infected with 2009 pandemic influenza A (H1N1) with pneumonia and acute kidney injury.
Patients infected with H1N1 virus may develop pneumonia and acute kidney injury (AKI). To determine the epidemiological characteristics, clinical features, management and out-comes of patients with confirmed H1N1 complicated by pneumonia and AKI and treatment with oseltamivir and to identify the prognostic indicators, we studied all the patients with a confirmed diagnosis of H1N1 infection with pneumonia and AKI, using real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay, between October 2009 and March 2010. H1N1 infection was confirmed in 20 patients with pneumonia and AKI; the mean age was 42.8 ± 18.2 years and 12 (60%) of the patients were males. ⋯ Fifteen (75%) patients required mechanical ventilation and 14 (70%) died. None of the health care workers developed influenza-like illness, when they received oseltamivir prophylaxis. Mortality was associated with higher Acute Physiology and Chronic Health Evaluation (APACHE) II, Sequential Organ Failure Assessment score (SOFA), Multiple Organ Dysfunction Score (MODS), XRChest score, in addition to requirement of inotrope, ventilator support, renal replacement therapy (RRT), and presence of underlying risk factor for severe disease.

[Severe acute respiratory infection in Cuban patients during the influenza A(H1N1) pandemic in Cuba, 2009].
On April 2009, the Mexican health authorities reported increased hospitalization indexes caused by pneumonia with high mortality rates to the Pan-American Health Organization (PAHO). The National Epidemiological Surveillance System of Mexico noticed that this increase mainly occurred in the 20-40 year old population. A new type of swine influenza A (H1N1) virus was identified by laboratory studies as the etiological agent of the first pandemic of the 21st century. On April 26 2009, the National Anti-pandemic Plan was activated by the Cuban Ministry of Public Health, and on May 7th, the lab-confirmed index case appeared. An integrated surveillance system with laboratory confirmation was set up. ⋯ The comprehensive analysis of these results contributes to the national and regional surveillance of respiratory viruses for the improvement of the prevention and control programs of the acute respiratory infections.
