Abstract
INTRODUCTION H7N9 infection has raised serious concerns worldwide. Pregnant women were considered to be at a high risk of influenza infection. Normal pregnancy was dependent on T helper (Th) 2 deviation. However, whether pregnancy influences the immune status of influenza H7N9 patients has not been reported. CASE REPORT Here, we reported a case of pregnant woman in the first trimester with H7N9 infection compared with the two non-pregnant female H7N9 patients for clinical features and relevant immunological changes. We found that there were no differences in plasma levels of Th1 and Th2 cytokines between the pregnant and non-pregnant patients, and there was no Th2 deviation in the acute phase. However, the Th2 deviation was recurrent along with the clearance of infection in the H7N9 pregnant patient. CONCLUSION These cases highlighted that the pregnant patient infected with H7N9 could induce an effective Th1 immune response equal to that of non-pregnant patients with H7N9 virus infection, although the pregnancy itself could lead to a Th2 deviation. These data suggested that pregnant patients could acquire a similar antiviral response for H7N9 infection versus non-pregnant patients.

[PMID: 24144035 DOI: 10.1016/s1995-7645(13)60179-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2013] [Revised: 10/15/2013] [Accepted: 11/15/2013] [Indexed: 10/26/2022] Open
Abstract
OBJECTIVE To explore effect of different anesthesia methods and different anesthetics on erythrocyte immune function in mice. METHODS The mice were anesthetized by isoflurane and ether inhalation, and also under intraperitoneal anesthesia with sodium pentobarbital and chloral hydrate. Blood was collected from the ventro-cardinal vein. Automatic blood cell analyzer was used for routine blood examination, and the canthine oxidase method was used to measure the superoxide dismutase (SOD) activity. Lipid peroxidation product malondialdehyde (MDA) was measured with TBA, and glutathione peroxidase (GSH-Px) was measured with DTNB, and then the effect of different anesthesia methods and different anesthetics on erythrocyte immune function in mice was observed. RESULTS Hct level of chloral hydrate intraperitoneal injection group was significantly higher than the other three groups (P<0.05). And the MDA levels in the pentobarbital sodium group were significantly higher than the other three groups (P<0.05). SOD and GSH-Px of the chloral hydrate and sodium pentobarbital intraperitoneal injection group were significantly lower than the other two groups; RBC-C 3bRR and RBC-ICR of the chloral hydrate and sodium pentobarbital intraperitoneal injection group were significantly lower than the other two groups. CONCLUSIONS Different drugs can induce changes in immune function of mice at different levels. Isoflurane and ether have less damage to animal body, while chloral hydrate and sodium pentobarbital intraperitoneal injection have a certain inhibitory effect on the animal body respiratory system and can cause greater damage to the body. Therefore, the reasonable selection and control of anesthetics are very important in order to avoid the experimental errors caused by anesthesia.

Abstract
PURPOSE Africa, as the rest of the world, was touched by the 2009 pandemic influenza A(H1N1). In the literature, a few publications covering this subject emerged from this continent. We prospectively describe baseline characteristics, treatment and outcomes of consecutive critically ill patients with confirmed 2009 influenza A(H1N1) in the intensive care unit (ICU) of Sfax hospital. METHODS From 29 November 2009 through 21 January 2010, 32 patients with confirmed 2009 influenza A(H1N1) were admitted to our ICU. We prospectively analysed data and outcomes of these patients and compared survivors and dead patients to identify any predictors of death. RESULTS Patients were young (mean, 36·1 [SD], 20·7 years) and 21 (65·6%) of whom had co-morbidities. During ICU care, 29 (90·6%) patients had respiratory failure; among these, 15 (46·9%) patients required invasive ventilation with a median duration of 9 (IQR 3-12) days. In our experience, respiratory dysfunction can remain isolated but may also be associated with other dysfunctions or complications, such as, septic shock, seizures, myasthenia gravis exacerbation, Guillan-Barre syndrome, acute renal failure, nosocomial infections and biological disturbances. The nine patients (28·1%) who died had greater initial severity of illness (SAPS II and sequential organ failure assessment (SOFA) scores) but also a higher SOFA score and increasing severity of organ dysfunction during their ICU evolution. CONCLUSION Critical illness from the 2009 influenza A(H1N1) in Sfax occurred in young individuals and was associated with severe acute respiratory and additional organ system failure. SAPS II and SOFA scores at ICU admission, and also during evolution, constitute a good predictor of death.

Abstract
OBJECTIVES to describe the characteristics, treatment and outcome of critically ill patients with influenza A(H1N1) infection at St Pierre Hospital in Reunion Island during the 2009 outbreak, as well as the measures of care reorganization implemented to face them. PATIENTS AND METHODS prospective observational study of probable and confirmed cases of influenza A (H1N1)/2009 infection concerning hospitalized patients in a polyvalent intensive care unit (ICU). RESULTS thirteen patients have been included between August and September 2009. Three (23 %) didn't have any medical history. The median age was 42 [22-69]. Eleven have required pulmonary ventilation for 10.3 days (± 8). Three (23 %) have developed an ARDS. Three patients (23 %) died. To cope with the influx of cases and considering our situation of geographic isolation, it has been needed to totally rework the organization of care: set-up of a specific welcoming channel, division into sectors of the department, opening of additional beds, new on-duty assignment, inter and intra hospital cooperation. CONCLUSION reunion Island has been an experimental lab of crisis management during the H1N1/2009 epidemic, several months ahead of the mother country. To anticipate the reorganization of care in intensive care units during an outbreak period, particularly in small units or units isolated like ours, looks to us a must so to quietly face a sharp influx of patients.
