Treatment of laryngopharyngeal reflux improves asthma symptoms in asthmatics

Objective. Laryngopharyngeal reflux (LPR) is defined as the movement of gastric content toward laryngopharynx and is a common occurrence in patients with asthma. This study aimed (1) to determine the incidence of LPR in patients with asthma by assessment of symptom scores and indirect laryngoscopy and (2) to determine the effect of LPR treatment on asthma symptom scores. Methods. A total of 28 patients with mild to moderate asthma (24 women, 4 men, mean age 46 +/- 6 years) were included in the study, and after all patients completed LPR and asthma symptom questionnaires, indirect videolaryngoscopy was performed. In patients with LPR, daily treatment with 40 mg pantoprazole was administered for 3 months. Symptom score assessment and indirect videolaryngoscopic examination were repeated at the end of treatment. Results. A diagnosis of LPR was made in 21 of 28 patients (75%) by indirect laryngoscopy. A statistically significant improvement was observed in asthma and LPR symptoms in patients with LPR after the treatment (p = 0.001 and p < 0.001, respectively). Conclusions. LPR is a frequent condition in asthma patients. When the LPR symptom questionnaire and indirect laryngoscopy findings are suggestive of LPR, treatment with a proton pump inhibitor provides improvement in both asthma and LPR symptoms

The Endocrinologic Changes in Critically III Chronic Obstructive Pulmonary Disease Patients

Background: Alterations in the neuroendocrine system occur during critical illness. Chronic obstructive pulmonary disease (COPD) itself causes hormonal changes. The aim of this study was to determine neu roendocrine hormones of COPD patients with acute respiratory failure and to investigate the relationship between hormonal changes, mortality, and morbidity. Methods: We enrolled 21 patients (13 F/8 M) with COPD exacerbation requiring artificial airway support. Blood samples were collected on admission to the ICU, and on the day of hospital discharge. Eighteen healthy people were included as controls. Results: Female patients had lower luteinizing hormone (LH), follicle stimulating hormone (FSH), and free triiodothyronine (fT3), and higher prolactin (PRL) levels than controls on admission to the ICU (FSH: 70.3 vs. 29.3 mIU/mL; LH: 26.6 vs. 6.8 mIU/mL; fT3: 2.9 vs. 2.0 pg/mL; PRL: 12.4 vs. 21.3 ng/mL). Male patients had low testosterone and TSH and high PRL but only changes in TSH and PRL reached statistical significance (testosterone: 3.5 vs. 1.5 ng/mL, TSH: 1.1 vs. 0.5 uIU/mL, PRL: 9.7 vs. 14.2 ng/mL). Female patients had lower fT3 than males (fT3(female): 2.7 vs. fT3(male): 2.0 pg/mL). On follow-up, significantly elevated FSH and fT3 and decreased estradiol concentrations were documented among recovered women (FSH: 28.4 vs. 46.6 mIU/mL, fT3,: 2.0 vs. 2.6 pg/mL, E-2: 27.7 vs. 19.0 pg/mL). Patients had high C-reactive protein levels and acute physiologic and chronic health evaluation II scores. Mortality rate was 9.5% and a negative correlation between E-2 and duration of noninvasive mechanical ventilation and length of hospital stay was found in male patients. Conclusion: Men and women with acute respiratory failure in the presence of COPD develop significant changes in the neuroendocrine axis. Hormonal suppression vanishes with disease improvement

Noninvasive positive pressure ventilation in unplanned extubation

Background:Unplanned extubation is quite common in intensive care unit (ICU) patients receiving mechanical ventilatory support. The present study aimed to investigate the effectiveness of noninvasive positive pressure ventilation (NPPV) in patients with unplanned extubation. Materials and Methods: A total of 15 patients (12 male, age: 57 number 24 years, APACHE II score: 19 number 7) monitored at the medical ICU during the year 2004 who developed unplanned extubation were included in the study. NPPV was tried in all of them following unplanned extubation. Indications for admission to the ICU were as follows: nine patients with pneumonia, three with status epilepticus, one with gastrointestinal bleeding, one with cardiogenic pulmonary edema and one with diffuse alveolar bleeding. Results:Eleven of the patients (74) were at the weaning period at the time of unplanned extubation. Among these 11 patients, NPPV was successful in 10 (91) and only one (9) was reintubated due to the failure of NPPV. The remaining four patients (26) had pneumonia and none of them were at the weaning period at the time of extubation, but their requirement for mechanical ventilation was gradually decreasing. Unfortunately, an NPPV attempt for 6-8 h failed and these patients were reintubated. Conclusions:Patients with unplanned extubation before the weaning criteria are met should be intubated immediately. On the other hand, when extubation develops during the weaning period, NPPV may be an alternative. The present study was conducted with a small number of patients, and larger studies on the effectiveness of NPPV in unplanned extubation are warranted for firm conclusions

Evaluation of Airway Resistance in Children with Juvenile Idiopathic Arthritis

Background: Pneumonitis, pleuritis, and pulmonary interstitial infiltration have been described in patients with juvenile idiopathic arthritis (JIA). However, the pulmonary involvement of JIA is not often clinically apparent. There are few studies based on pulmonary function in children having only a diagnosis of JIA. The aim of the present study is to determine whether children with JIA have airway resistance and flow impairments measured by easily applied interrupter technique. Method: We performed interrupter resistance (Rint) measurements in children with JIA and in healthy control subjects who had no respiratory symptoms or diseases. Results: Fifty-eight children with the diagnosis of JIA (Mean age = 12.5 +/- 2.75 years; range 7-17 years) and 33 healthy subjects (Mean age = 11.8 +/- 2.62 years; range 6-16 years) were included in the study. The mean value of tidal peak flow during expiration measured by the interrupter technique was significantly lower in the JIA study group (0.73 +/- 0.11 L/s) compared to the healthy control group (0.79 +/- 0.08 L/s; p = 0.01). Rint values measured during inspiration (Rint(insp)) and during expiration (Rint(exp)) were higher in the JIA study group (Rint(insp) = 0.28 +/- 0.16 Kpa/L/s; Rint(exp) = 0.30 +/- 0.50 Kpa/L/s) compared to the healthy control group (Rint(insp) = 0.26 +/- 0.11 Kpa/L/s; Rint(exp) = 0.23 +/- 0.08 Kpa/L/s; p > 0.05). There was also a positive correlation between C-reactive protein level and median expiratory interrupter resistance (Rint(exp); r = 0.50, p = 0.005). Conclusion: The interrupter technique is a noninvasive and feasible technique and can be used to assess airway abnormalities in children with JIA who cannot successfully complete spirometry

Incidence and treatment results of laryngopharyngeal reflux in chronic obstructive pulmonary disease

Laryngopharyngeal reflux (LPR) is defined as the movement of gastric content towards the larynx and the pharynx and it may cause respiratory symptoms or difficulty in their control. We aimed to find the frequency of LPR in chronic obstructive pulmonary disease (COPD) patients and to investigate its effect on COPD symptoms and the results of its treatment. At baseline 30 (20 male, 10 female, mean age: 65 +/- A 10 years) COPD patients completed LPR and COPD symptom questionnaires and 13 (44%) were diagnosed with LPR based on laryngeal examination. Patients with LPR were given 2 months of PPI treatment, after which LPR and COPD symptom questionnaires, laryngeal examinations and pulmonary function tests were repeated. Following the treatment, significant improvements in COPD symptom index, LPR symptom index and laryngeal examination findings were observed in patients with LPR (P < 0.01, P < 0.01, P < 0.0001, respectively). Treatment of LPR resulted in a significant improvement in the symptoms of COPD
