Cytokine levels in bronchoalveolar lavage and serum in 3 patients with 2009 influenza A(H1N1)v severe pneumonia.

Introduction: Pandemic Influenza A (H1N1)v pneumonia has led to a notable increase of admissions to intensive care units. A cytokine-mediated inflammatory response has been well documented in pneumonia and acute respiratory distress syndrome. However, few studies have focused on the role of these inflammatory mediators in infections caused by the Influenza A (H1N1)v. In this study, we assess the inflammatory response mediated by cytokines at the local and systemic levels in three cases of severe pneumonia caused by Influenza A (H1N1) virus. Methodology: Serum and bronchoalveolar lavage samples were obtained from three mechanically ventilated patients diagnosed with Influenza A (H1N1) virus pneumonia by bronchoscopic bronchoalveolar lavage. Levels of interleukin 6 (IL-6), interleukin 8 (IL-8), tumour necrosis factor alpha (TNFα) and interleukin 1 beta (IL-1ß) were meassured in these samples by enzyme-linked immunosorbent assay (ELISA). Results: High levels of C Reactive Protein, Procalcitonin below 1 ng/ml and absence of leukocytosis were common findings in all patients. TNF α and IL-1ß were not detected in the serum. IL-6 levels in serum were (94, pg/ml, 77 pg/ml and 84 pg/ml) respectively in the three patients, while IL-8 levels were (30,2 pg/ml, 128 pg/ml and 40,5 pg/ml). In the BAL samples, only one of the analysed cytokines, IL-1ß was present at detectable levels in two patients (21 pg/ml and 11 pg/ml respectively). Conclusions: Our results support previous findings which suggest that high levels of IL-6 and IL-8 in serum somehow participate in the inflammatory response in severe cases of pandemic influenza pneumonia.

Characterization of 23S rRNA domain V mutations in gastric biopsy patients from the eastern Amazon

Resistance of Helicobacter pylori to clarithromycin is characterised by simple point mutations in the 23S ribosomal RNA (rRNA) gene and is responsible for the majority of cases of failure to eradicate this bacterium. In this paper, we characterised the variability of the 23S rRNA gene in biopsies of patients with gastric pathologies in the eastern Amazon (Northern Region of Brazil) using PCR and sequencing. A total of 49 sequences of H. pylori strains were analysed and of those, 75.6% presented nucleotide substitutions: A2142G (3.3%), T2182C (12.9%), G2224A (6.45%), T2215C (61.3%), A2192G (3.3%), G2204C (6.4%) and T2221C (6.4%). Of the mutations identified, four are known mutations related to cases of resistance and 16.1% are not yet described, revealing a high prevalence of mutations in the H. pylori 23S rRNA gene among the strains circulating in the in the eastern Amazon. The high prevalence in individuals with gastric pathologies in the Northern Region of Brazil demonstrates the need for characterising the profile of these strains to provide correct therapy for patients, considering that mutations in this gene are normally associated with resistance to the primary medication used in controlling H. pylori infection.
