Abstract Background Chlamydia pneumoniae is a common cause of atypical community acquired pneumonia (CAP). The diagnostic approach of chlamydial infections remains a challenge. Diagnosis of delayed chlamydial-associated complications, involving complex autoimmune pathophysiological mechanisms, is still more challenging. C. pneumoniae-related cardiac complications have been rarely reported, including cases of endocarditis, myocarditis and pericarditis. Case presentation A 40-year old female was hospitalized for pleuropericarditis following lower respiratory tract infection. The patient had been hospitalized for CAP (fever, dyspnea, chest X-ray positive for consolidation on the left upper lobe) 5 weeks ago and had received ceftriaxone and moxifloxacin. Four weeks after her discharge, the patient presented with fever, shortness of breath and pleuritic chest pain and was readmitted because of pericardial and bilateral pleural effusions (mainly left). The patient did not improve on antibiotics and sequential introduction of colchicine and methylprednisolone was performed. The patient presented impressive clinical and laboratory response. Several laboratory and clinical assessments failed to demonstrate any etiological factor for serositis. Chlamydial IgM and IgG antibodies were positive and serial measurements showed increasing kinetics for IgG. Gold standard polymerase chain reaction of respiratory tract samples was not feasible but possibly would not have provided any additional information since CAP occurred 5 weeks ago. The patient was discharged under colchicine and tapered methylprednisolone course. During regular clinic visits, she remained in good clinical condition without pericardial and pleural effusions relapse. Conclusions C. pneumoniae should be considered as possible pathogen in case of pleuritis and/or pericarditis during or after a lower respiratory tract infection. In a systematic review of the literature only five cases of C. pneumoniae associated pericarditis were identified. Exact mechanisms of cardiovascular damage have not yet been defined, yet autoimmune pathways might be implicated.

BackgroundWe developed the chronic obstructive pulmonary disease (COPD)-Lower Respiratory Tract Infection-Visual Analogue Score (c-LRTI-VAS) in order to easily quantify symptoms during exacerbations in patients with COPD. This study aimed to validate this score.MethodsIn our study, patients with stable COPD as well as those with an acute exacerbations of COPD (AECOPD) were included. The results of c-LRTI-VAS were compared with other markers of disease activity (lung function parameters, oxygen saturation and two health related quality of life questionnaires (St Georges Respiratory Questionnaire (SGRQ) and Clinical COPD Questionnaire (CCQ)) and validity, reliability and responsiveness were assessed.ResultsEighty-eight patients with clinically stable COPD and 102 patients who had an AECOPD completed the c-LRTI-VAS questionnaire. When testing on two separate occasions for repeatability, no statistically significant difference between total scores was found 0.143 (SD 5.42) (p=0.826). Internal consistency was high across items (Cronbach’s apha 0.755). Correlation with SGRQ and CCQ total scores was moderate to high. After treatment for hospitalised AECOPD, the mean c-LRTI-VAS total score improved 8.14 points (SD 9.13; p≤0.001).Conclusionsc-LRTI-VAS showed proper validity, responsiveness to change and moderate to high correlation with other questionnaires. It, therefore, appears a reliable tool for symptom measurement during AECOPD.Trial registration numberNCT01232140.

Abstract We sought to examine the influence of clinically severe lower respiratory tract infection on pulmonary artery pressure in children having CHD with post-tricuspid left-to-right shunt, as it may have physiological and clinical implications. In a prospective single-centre observational study, 45 children with post-tricuspid left-to-right shunt and clinically severe lower respiratory tract infection were evaluated during the illness and 2 weeks after its resolution. Pulmonary artery systolic pressure was estimated non-invasively using shunt gradient by echocardiography and systolic blood pressure measured non-invasively. Median pulmonary artery systolic pressure during lower respiratory tract infection was only mildly (although statistically significantly) elevated during lower respiratory tract infection [60 (42–74) versus 53 (40–73) mmHg, (p < 0.0001)]. However, clinically significant change in pulmonary artery systolic pressure defined as the increase of >10 mmHg was present in only 9 (20%) patients. In the absence of hypoxia or acidosis, only a small minority (9%, n = 4) showed significant pulmonary artery systolic pressure rise >10 mmHg. In the absence of hypoxia or acidosis, severe lower respiratory tract infection in patients with acyanotic CHD results in only mild elevation of pulmonary artery systolic pressure in most of the patients.

Abstract Background Respiratory Syncytial Virus (RSV) is one of the most common causes of childhood lower respiratory tract infection (LRTI) worldwide. While financial burdens have been documented, there are few data on parental psychological stress associated with RSV hospitalizations. We evaluated the psychological stress and anxiety of parents whose children were hospitalized with RSV. Methods During the 2019-2020 RSV season, parents with children &lt; 5 years of age hospitalized with laboratory-confirmed RSV LRTI at Primary Children’s and Riverton Hospitals in Salt Lake City, Utah, were surveyed in person, and online after discharge. As part of the survey, parents completed the State-Trait Anxiety Inventory for Adults (STAIAD) instrument (short form) and the parental stressor scale (PSS). We evaluated the difference in parental stress and anxiety reported during hospitalization and at 2-weeks post-discharge using a paired t-test. Results Among 284 Salt Lake County resident children &lt; 5 years, and hospitalized with RSV LRTI, 75 (26%) and 57 (20%) parents completed both surveys on admission and at 2-weeks post-discharge respectively. In 11 of 20 STAIAD items gauging stress and anxiety, parents reported higher levels of stress and anxiety whilst their children were admitted compared to post-discharge (Table 1). Parents’ average score on several items associated with a “positive outlook,” e.g. I feel calm, significantly improved (p &lt; 0.05) at 2-weeks post-discharge. Similarly, several items associated with a “negative outlook,” e.g. I am worried, significantly decreased (p &lt; 0.05) at 2-weeks post-discharge (Table 1). For the PSS items, ≥ 50% of parents rated 15 out of 25 as being “very or extremely stressful”, including: feeling helpless about how to help my baby; my baby’s unusual or abnormal breathing; and when my baby seemed to be in pain (Table 2). Estimates of Psychological Burden of RSV lower respiratory tract infection (LRTI) Hospitalization of Children &lt;5 Years of Age on Parents: State-Trait Anxiety Inventory for Adults (STAIAD) Estimates of Psychological Burden of RSV lower respiratory tract infection (LRTI) Hospitalization of Children &lt;5 Years of Age on Parents: Parental Stressor Scale (PSS) Conclusion RSV LRTI hospitalization among children &lt; 5 years of age, imposed a significant psychological stress and anxiety on parents, which generally persisted up to 2-weeks post-discharge. Prevention of RSV infection through vaccines and immunoprophylaxis will help ease parental psychological burden associated with RSV hospitalization.
