However, the prevalence of polycythemia and its possible risk factors in patients with COPD have not been widely studied. In the past, it was known that patients with COPD had a high prevalence of polycythemia.However, owing to the advances in the management of patients with COPD and the use of long-term oxygen therapy to correct hypoxemia in patients with advanced COPD, its frequency is decreasing. Aim The current research was done to evaluate the frequency of polycythemia and its effects in patients with COPD in Minia Cardiothoracic University Hospital. Patients and methods A total of 100 patients with COPD were included within the study. They were assessed for complete demographic and clinical data. Spirometry and arterial blood gases were evaluated. Complete blood count, serum iron, total iron-binding capacity, and erythropoietin level were measured.Patients were divided into two groups: group I, nonpolycythemic patients (86 patients), and group II, polycythemic patients (14 patients). Results Polycythemia was present in 14 (14%) patients. Polycythemic patients had a higher modified Medical Research Council dyspnea grade (P=0.001) and a higher number of exacerbations per year (0.02). There was also a significant increase in serum iron level (170.9 ± 9.6 µg/dl) and total iron-binding capacity (377.1 ± 14.8 µg/dl) with lower erythropoietin (24.04 ± 3.8 mU/ml) in group II compared with group I (134.4 ± 27.4 µg/dl, 310.9 ± 40.1 µg/dl, and 41.9 ± 10.3 mU/ml, respectively) (P=0.001, 0.001, and 0.001, respectively). Conclusion Polycythemia was present in 14% of the studied patients. It was associated with a significantly higher grade of dyspnea and an increased number of exacerbations.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78397023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using predictors of fungal infection helps to guide the diagnosis and treatment in these cases and save their lives. Patients and methods A total of 257 patients with moderate to severe COVID-19 pneumonia were examined in this retrospective study at Al Qassimi Hospital of EHS. An assessment of clinical, laboratory, and radiologic findings was performed upon admission. The data were collected and analyzed. Results Overall, 32% of critically ill COVID cases had fungal infection; 47% of them were candida, whereas aspergillosis and yeast were positive in 26.5% each. At the time of hospitalization, computed tomography chest findings had a strong correlation with fungal culture results in COVID-19 cases. Fungal infection in COVID-19 cases correlated strongly with metabolic acidosis, high erythrocyte sedimentation rate, high blood sugar, need for mechanical ventilation at admission, vasopressor use, renal replacement, long duration of steroid treatment, long stay in ICU, and long duration on mechanical ventilation. The longer the duration of PCR positivity, the higher the incidence of positive sputum fungal culture result. Conclusion COVID-19-infected patients with other risk factors for fungal infections should always be considered to have fungal infections if pathogenic organisms are isolated from respiratory secretions or other microbiological or immunological markers appear positive. Computed tomography chest finding in COVID-19 cases is an important predictor for fungal infection.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88679366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing number of inhaler devices have been approved by drug regulatory authorities. Failure to use the drug delivery devices properly has been shown to affect the control of diseases negatively. Research studies concerning the inhalation devices handling difficulties have been published previously; however, local data are lacking. Aim We aimed to study the technical errors among patients while handling the different available inhaler devices. We also aimed to compare between different devices regarding usage prevalence, duration of use and patient adherence. Patients and methods The study was a prospective, cross-sectional, observational study. It was conducted on patients aged greater than 12 years, who used an inhaler regularly for more than 4 weeks. Each patient demonstrated the inhalation technique using their inhaler, showing their usual inhalation technique. Technical mistakes that are likely to make therapy ineffective using devices metered-dose inhaler (MDI) and dry powder inhaler (Diskus, Turbohaler, Breezhaler, Handihaler, Ellipta) were recorded. A statistics analysis was then performed. Results A total of 221 patients were enrolled, comprising 116 (52.5%) males and 105 (47.5%) females, with a mean age of 47.6 ± 18.5 years. Bronchial asthma was the most frequent disease in 191 (84.6%) patients. The enrolled 221 patients used a total of 280 inhalation maneuvers with six different inhaler devices: 97 (34.6%) used MDI, 82 (29.3%) used Turbohaler, 58 (20.7%) used Diskus, 27 (9.7%) used Handihaler, and nine (3.2%) used Ellipta. A total of 167 (75.6%) patients used a single device, whereas the MDIs had the longest duration of use among the studied cases (mean: 56.15 months). The compliance was much higher among patients using Turbohaler and Handihaler (70 and 85%, respectively). Analysis of technical errors experienced by the studied patients shows that using Diskus or Turbohaler is accompanied by more frequent error compared with other devices (1.82 per patient and 1.73, respectively), whereas Handihaler had the least recorded error per patient (0.48). Conclusion Inhaler mishandling and compliance remain common problem in our locality. A good inhalation technique is mainly affected by the type of the device. Instructions given by health caregivers are the only modifiable factors useful for decreasing inhaler mishandling.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80495973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and methods This observational prospective study included 50 patients with ILD from the outpatient clinic of Fayoum Chest Hospital. All patients had positive serology for HCV. They were categorized into two groups based on the results of a PCR test that determined their blood viremia: group 1 (viremic group) and group 2 (nonviremic group). Both groups were subjected to spirometry, HRCT of the chest, diffusing lung capacity for carbon monoxide, arterial blood gases, and abdominal ultrasound. Results The honeycombing pattern in HRCT was more common in the viremic group(P=0.006), especially with higher level of viremia. Moreover, forced vital capacity (FVC%) value showed statistically significant reduction in the viremic group (P=0.006).

The interrelationship between COVID-19 and autoimmunity is complex and bidirectional. There was world concern about the severity of COVID infection in rheumatic patients; however, other studies have found no difference between them and the general population. Objectives To study the clinical character of rheumatic disease patients (RDP) with COVID and the outcome and compare this outcome with the nonrheumatic patients. Patients and methods This investigation was conducted retrospectively; all patients were recruited from quarantine hospitals. This study included 100 randomly selected COVID-19 patients with RDP and 200 COVID-19 patients with comorbidities other than rheumatological disease. Results The RDP presented with fever in 75%, and more than 60% developed cough and dyspnea. One-third of the patients developed anosmia and 25% lost the taste sensation; 72% of the studied RDP were admitted to Ain Shams University’s quarantine hospitals. Mean of the patients’ hospital stay of RDP was 15.4 ± 6.7; 38% of those were admitted to the ICU. Moreover, 27% had needed mechanical ventilation, 14% developed cytokine storm, and finally, 11% of RDP died due to COVID infection; 89% of RDP had been resolved from COVID infection. Conclusions Three-quarters of the recruited patients needed hospitalization. The mortality was 11%. The frequency of hospitalization and mortality of RDP were related significantly to the severity of COVID-19 infection, presence of comorbidity, and use of cyclophosphamide.

Chemokine receptor 3 (CCR3) which is expressed over eosinophils and Th2 lymphocytes has a significant role in chemoattraction of those cells to inflammatory sites which symbolizes a key mechanism in asthma. Aim A trial to detect the association between CCR3 T51C gene polymorphism and different asthma phenotypes (allergic march phenotype, cough-predominant asthma phenotype, and wheeze-predominant asthma phenotype). Patients and methods A case–control study was conducted comprising 60 asthmatic patients and 100 healthy controls. Asthmatic children were divided into three groups of 20 patients each, group 1 allergic march phenotype (wheeze asthma phenotype with allergic rhinitis and/or atopic dermatitis), group 2 cough-predominant asthma phenotype, and group 3 wheeze-predominant asthma phenotype. The included cases and controls underwent total serum immunoglobulin E (IgE) using the enzyme-linked immunosorbent assay technique, peripheral eosinophilic percent, and PCR-restriction fragment length polymorphism for CCR3 T51C gene polymorphism. Results Asthmatic children showed significant increase in crowding index, family history of bronchial asthma, parental smoking, parental consanguinity, and total serum IgE than controls. Also, the CCR3 T51C gene polymorphism was found in Egyptian asthmatic children but no significant association concerning this polymorphism and different clinical asthma phenotypes was detected. Conclusion In conclusion, allergic march phenotype showed significant higher frequency with positive family history of asthma when compared with cough and wheezy asthma phenotypes. Also, parental consanguinity showed higher frequency in cough phenotype compared with allergic march phenotype. Furthermore, the CCR3 T51C gene polymorphism is found to be present in Egyptian asthmatic children, but there is no significant association between CCR3 T51C gene polymorphism and different asthma phenotypes.
