For the first time in Thessaloniki, Greece, 15-year allergenic pollen records were conducted. Clinical observations confirm that the pollen mainly implicated in respiratory allergy symptoms are grasses, olive and wall pellitory.
In a selected cohort of asthmatic patients, obesity is significantly associated with increased urinary leukotriene levels. Alterations of leptin/adiponectin balance may be related to the presence of leukotriene inflammation in obese asthmatic patients.
FeNO and EBC pH levels may identify patients with not well-controlled asthma. However, their performance was inferior to clinical judgment and may be limited to selected subgroups of asthmatic patients.
Mycobacterium tuberculosis infection in patients with cystic fibrosis (CF) is rare. We report a 22-year-old CF patient with high fever, dyspnea and weight loss that progressively worsened over 2 weeks before admission. The patient suffered from liver cirrhosis, was colonized with Pseudomonas aeruginosa and had been repeatedly hospitalized for pulmonary infections. The patient was treated initially as for an exacerbation of P. aeruginosa infection, but tuberculosis (TBC) was suspected due to lack of improvement. A CT of the chest revealed enlarged bilateral cavities in the upper and middle lobes. A tuberculin skin test was positive, and M. tuberculosis nucleic acid was isolated from sputum samples. After receiving first-line anti-TBC drugs for 1 month, the patient's condition continued to worsen so molecular drug susceptibility testing was performed. Multidrug-resistant TBC was discovered, leading to a change in regimen. The patient was treated with ethionamide, moxifloxacin, linezolid, amikacin, imipenem/cilastatin and rifabutin and showed a remarkable clinical improvement. Although nontuberculous mycobacteria are more common in CF, the possibility of TBC should not be ignored. In that setting, early suspicion of infection due to resistant M. tuberculosis can be life saving.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
