Abstract Background Antibiotic treatment decisions in severely ill patients must often be made in the absence of microbiologic results. The recently FDA-cleared BioFire® FilmArray® Pneumonia Panel (PN) detects fifteen bacteria semi-quantitatively, three atypical pneumonia bacteria, eight viruses, and seven antimicrobial resistance markers by multiplex PCR in ~1 hour in the laboratory. Previous reports have shown the PN panel bacterial detections are highly accurate, even when routine culture had no growth. Methods Consecutive bronchoalveolar lavage and endotracheal specimens submitted for culture between June-September 2018 from 270 patients with sufficient clinical and laboratory data were tested with the PN panel. Patients were divided into 3 groups: 1) both culture and PN panel positive, 2) PN panel positive but culture uninformative (no growth or normal flora) and 3) patients with no PN panel detections. Results Groups 1 and 2 had significantly higher maximum temperatures on the day of culture (p=0.00036, ANOVA with Bonferroni correction), higher levels of an inflammatory response as measured by % polymorphonuclear leukocytes in bronchoalveolar lavage (p=0.00025, ANOVA with Bonferroni correction) and the gram stain report of white blood cells, as previously reported 4. Conclusions Both group 1 (culture and PN panel positive), and group 2 (PN panel positive but culture uninformative) had higher levels of host response inflammatory responses compared with group 3 that had no targets detected, suggesting PN panel detections need to be interpreted in the clinical context, even if cultures are discordant. Depending on laboratory turnaround time, there could be opportunity for improved diagnosis and antibiotic stewardship.

Background : Pertussis is an acute bacterial infection of the respiratory tract caused by Bordetella pertussis. Without immunization and adequate therapy, the disease will evolve to severe complication. The purpose of the case report was to describe the diagnosis and treatment of severe pertussis from a Papuan infant in remote mountainous area of Papua. Case report : A 5 months old male Papuan infant, lived in the mountainous area of Papua was admitted to the hospital after 1 week of cough. No history of DPT immunization. Physical examination revealed continuous coughing, sunken fontanel, sunken eyes, nasal flaring, chest retraction, and bilateral crackles. Laboratory examination showed white blood count was 87,600/µL, CRP 48 mg/dL, ASTO negative. He deteriorated and referred to ICU for Mechanical Ventilation. His bronchoalveolar lavage taken at day 10 confirmed Pseudomonas from the culture and Bordetella pertussis by the PCR. Discussion : Children lived in the Honai without enough ventilation at the area of low coverage of immunization are susceptible to pneumonia. This infant was treated with Erythromicin and Ceftriaxon on admission with the idea that they will cover broad spectrum of antibacterial, atypical pneumonia or Pertussis infection. The Sputum culture from bronchoalveolar lavage showed Pseudomonas resistant to Amoxillin and Erythromicin, but sensitive to Amikacin. This finding explains why there was no clinical improvement after 2 weeks of Erythromicin. After changing to Amikacin, the clinical condition improved in 7 days. Conclusions : On the area with low immunization coverage, the pediatrician should consider Pertussis as one of the possible etiology of pneumonia, and start treating early to get the better result and avoid severe complication. It recommeded that all countries should consider expanding vaccination strategies to include adding Pertussis booster doses to pre-school children (4-6 years old), to adolescent and to those specific adults that have the highest risk of transmitting Bordetella pertussis infection to vulnerable infants.

Pneumocystis carinii (PC) is an organism capable of causing fatal pneumonia in immune suppressed individuals and has recently gained prominence because of its association with AIDS. A similar organism occurs in rats and infection may be induced with cortisone injections. In order to isolate PC for further study bronchoal veol ar lavage (BAL) was performed. Differences in the ul trastructure of BAL-obtained organisms and PC in situ were observed and are herein reported.

Eosinophils are important to the pathogenesis of allergic asthma, and are increased in bronchoalveolar lavage within four hours after bronchoprovocation of allergic asthmatic patients, and remain significantly increased up to 24 hours later. While the components of human eosinophil granules have been recently isolated and purified, the mechanisms of degranulation have yet to be elucidated.We obtained blood from two volunteers who had a history of allergic rhinitis and asthma and a positive skin test (5x5mm wheal) to Alternaria and Ragweed. Eosinophils were obtained using a modification of the method described by Roberts and Gallin.

There is a great need for the development of a rapid and reliable bioassay to evaluate the pulmonary toxicity of inhaled particles. A number of methods have been proposed, including lung clearance studies, bronchoalveolar lavage analysis, and in vitro cytotoxicity tests. These methods are often limited in scope inasmuch as they measure only one dimension of the pulmonary response to inhaled, instilled or incubated dusts. Accordingly, a comprehensive approach to lung toxicity studies has been developed.To validate the method, rats were exposed for 6 hours or 3 days to various concentrations of either aerosolized alpha quartz silica (Si) or carbonyl iron (CI) particles. Cells and fluids from groups of sham and dust-exposed animals were recovered by bronchoalveolar lavage (BAL). Alkaline phosphatase, LDH and protein values were measured in BAL fluids at several time points postexposure. Cells were counted and evaluated for viability, as well as differential and cytochemical analysis. In addition, pulmonary macrophages (PM) were cultured and studied for morphology, chemotaxis, and phagocytosis by scanning electron microscopy.
