Neoplastic natural killer (NK) cells overexpress Fas ligand (FasL), which may cause damage of Fas-bearing tissues. We report a patient with NK cell leukaemia who developed liver injury after pharyngitis. The NK leukaemic cells expressed functional FasL. In addition to soluble FasL, serum levels of interleukin-6 and interferon-gamma were increased dramatically when liver injury was aggravated. Moreover, hepatocytes expressed Fas and apoptotic hepatocytes were detected in the portal areas. These findings are consistent with the notion that inflammatory cytokines enhance the sensitivity to FasL and trigger apoptosis of hepatocytes in NK cell malignancies.

As the main target of influenza viral aggression, the respiratory tract is subject to easier bacterial infection superimposition. The researchers from Les Laboratoires Servier--France, managed to isolate a substance--fusafungine--from the microspore of the fungus Fusarium lateritium, which demonstrates unique anti-inflammatory and antibiotic action, and is the active ingredient of Bioparox Spray, an inhalant. The principal indications of Bioparox Spray for treatment of respiratory tract infections fall within the range from the sinuses to the finest alveolar duct, namely: rhinitis, sinusitis, tonsillitis, pharyngitis, laryngitis, tracheitis and bronchitis. In terms of technology Bioparox is unique due to the fact that 90% of the aerosol particles are less than one micron large, while generally the particles needed for penetration through the alveolar duct should be less than three microns. Due to such micronization, after inhalation Bioparox Spray reaches from the sinuses to the finest bronchial branches. Bioparox Spray possesses sound and broad antibiotic spectrum of action on the most common causative agents of respiratory infections, and more over, it acts upon Candida albicans, unlike the remaining broad-spectrum antibiotics. Bioparox Spray also has an independent anti-inflammatory effect by blocking the inflammation mediators: Bioparox Spray inhibits the synthesis of free radicals and the action of IL1 and TNF as pro-inflammatory factors, and it potentiates the action of IL2 and interferon-gamma which are anti-inflammatory factors. By its dual antibiotic and anti-inflammatory action Bioparox Spray is an excellent alternative to the conventional antibiotic therapy.

Streptococcus pyogenes is a major causative agent of tonsillitis or pharyngitis in children. Streptococcus pyogenes can persist in tonsils, and one-third of children treated with antibiotics continue to shed streptococci and have recurrent infections. Mouse nasal-associated lymphoid tissue (NALT) is functionally analogous to human oropharyngeal lymphoid tissues, and serves as a model for characterization of the mucosal innate immune response to S. pyogenes. Wild-type S. pyogenes induces transcription of both type I and interferon-gamma (IFN-gamma)-responsive genes, proinflammatory genes and acute-phase response proteins 24 h after intranasal infection. Invasion of NALT and the induction of the interferon response were not dependent on expression of antiphagocytic M protein. Intranasal infection induces a substantial influx of neutrophils into NALT at 24 h, which declines by 48 h after infection. Infection of IFN-gamma(-/-) [IFN-gamma knock-out mouse (GKO)] C57BL/6 mice with wild-type S. pyogenes resulted in local dissemination of bacteria to draining lymph nodes (LN), but did not lead to systemic infection by 48 h after infection. Infected GKO mice had an increased influx of neutrophils into NALT compared with immunocompetent mice. Thus, IFN-gamma-induced responses are required to prevent local dissemination of streptococci to the draining LN.

A 66-year-old woman complained of fever, sore throat, and neck pain due to pharyngitis and painful lymph node swelling. CBC revealed severe pancytopenia and markedly hypocellular marrow. The administration of antibiotics and granulocyte-colony stimulating factor (G-CSF) successfully ameliorated the inflammatory lesions, and hematopoiesis recovered. Causes for pancytopnenia was unlikely to be virus infection or drugs, and aplastic anemia was also unlikely since only the plasma levels of tumor necrosis factor-alpha (TNF-alpha) was markedly elevated, erythropoietin (EPO) was slightly elevated, interferon-gamma (IFN-gamma) was normal, and flow cytometric analysis for paroxysmal nocturnal hemoglobinuria (PNH)-type cells was negative. These results suggested that the cause of impaired hematopoiesis in the present patient might have been due to elevated TNF-alpha in overwhelming infection, although the pathogen was not identified.
