Baricitinib, an oral drug, is a selective inhibitor of Janus kinase (JAK) 1 and 2 and interferes with the intracellular signaling pathway of many cytokines and in combination with remdesivir may give good results in severe COVID-19 infection. Aim The aim was to assess the effect of baricitinib in severe COVID-19 pneumonia. Patients and methods A total of 30 patients with SARS-CoV-2-confirmed positive cases by nasopharyngeal swab/reverse transcriptase PCR with severe pneumonia received oral baricitinib 4 mg daily, and patients were followed for at least 14 days, unless previously discharged or dead. Results Patients were admitted to the ICU, with a mean duration of 11 days. All patients received high-flow oxygen with nonrebreathing mask. A total of 18 (60%) patients improved and 12 (40%) patients died. Moreover, 15 patients had comorbidities, and mortality was high in this group (10 patients). No serious adverse effects of baricitinib were detected in our study. All patients were hypoxic at admission. The mean oxygen saturation on room air was 70%. There was a statistically significant improvement in oxygenation on discharge after receiving treatment, with mean oxygen saturation of 90% on room air. Conclusion Baricitinib with remdesivir improves clinical status and oxygen saturation in patients with severe COVID-19 pneumonia with no serious adverse effects.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83914872","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}

Disturbance of sleep leads to adverse health problems with poor quality of life. This study researched the comparison of polysomnographic parameters between menopausal and childbearing women. Patients and methods This study was carried out on 47 women (divided into two groups of premenopausal and postmenopausal), who attended for polysomnography in the Unit of Sleep in the Department of Chest Diseases in Menoufia University Hospital from the period of September 2021 to September 2022. After taking informed written consent, all participants were subjected to history taking, full examination, Epworth sleepiness scale, STOP-Bang questionnaire, and polysomnography. Results This study was carried out on 47 women who were divided into two groups: group I (29 participants) in menopause with an age of 58.9 ± 6.3 (mean±SD) and group II (18 participants) in the childbearing period with an age of 37.28 ± 8.064 (mean±SD). Polysomnographic parameters showed statistically significant differences between both groups regarding sleep latency (min) (P=0.026), sleep efficiency% (P=0.019), apnea–hypopnea index (P<0.001), O2 desaturation index, and lowest O2 saturation during sleep (P<0.001 and 0.01, respectively). Conclusion Women in menopausal women experience more sleep disturbance, insomnia, and sleep breathing disorders than they did during the childbearing years. Women in this age group, therefore, require a more thorough assessment of sleep difficulties and other relevant variables.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85329909","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}

This recommends the use of analgesia and sedation in a balanced strategy to alter patients’ comfort and assist synchronization with mechanical ventilation while avoiding the downsides of excessive sedation. Objective The aim of the study was to compare between deep sedation and light sedation, analgesia, and no sedation strategies and their effects on the length of mechanical ventilation, and their effects on patients’ prognosis. Patients and methods This cohort prospective pilot study was conducted at the medical respiratory ICU at Ain Shams University Hospital in Cairo, Egypt, on 54 patients separated into four groups according to the type of sedation and analgesia suited for each patient’s severity condition. Results In this study, 54 mechanically ventilated patients in respiratory ICU were recruited. The patients were divided into group 1: no sedation or analgesia, group 2: analgesia only, group 3: light sedation, and group 4: deep sedation. There was a significant difference in Acute Physiology and Chronic Health Evaluation score and severity%, although the Acute Physiology and Chronic Health Evaluation score and severity % were the highest in group 1 (25.53, 55.11%) and group 4 (23.40, 47.68%), but the prognosis was poorer in group 4 and was affected by deep sedation (100% death rate) than that in group 1 (60.0%). The average infusion rate of fentanyl and the total dose were significantly different between groups, the highest being in the deep sedation group. ICU length of stay was nonsignificant between groups but it was lower in group 4 (median: 9 days) than other groups. The average rate of dormicum infusion in the deep sedation group was 5 µg, while there was no daily vacation period; so, it can be explained that higher doses of sedation and analgesia in group 4 affected their prognosis to be poorer than other groups. Delirium occurred in 80% of group 4 patients, but only in 6.7% of subgroups, indicating a highly significant difference. Complications either metabolic, cardiac, or hematologic in the postextubation period were higher in group 4 (60%), than in group 1 (47.7%), group 2 (40%), and group 3 (15%). Conclusion Light sedation and analgesia strategies with daily sedation interruption would have a better survival outcome and cause fewer issues in patients, who were on mechanical ventilation than a heavy sedation approach.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79602659","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}

Extrapulmonary TB (EPTB) can involve many systems. Diagnosis is often difficult. EPTB may be misdiagnosed with many other inflammatory, granulomatous, and neoplastic disorders. GeneXpert mycobacterium tuberculosis /rifampicin is a valuable test in diagnosis of pulmonary TB. There is limited research about its diagnostic role in EPTB. Patients and methods The aim of this study was to assess the diagnostic value of GeneXpert in EPTB. Samples from EPTB cases were sent for standard mycobacterial culture and GeneXpert assay. The sensitivity and specificity of GeneXpert were calculated. Results A total of 100 patients were included. Overall, 61 cases were definitely diagnosed as EPTB, whereas 39 cases were negative according to culture. GeneXpert was positive in 40 cases, which represent 65.6% of EPTB cases, and negative in 21 (34.4%) cases. Sensitivity and specificity of GeneXpert was 65.6 and 97.4%, respectively. The positive predictive value and negative predictive value were 97.4 and 64.4%, respectively. Conclusion GeneXpert is a rapid, valuable tool in diagnosis of patients with EPTB.

The COVID-19 outbreak has forced people toward a better approach to life owing to limited developments, confinement in closed areas, and severe hygiene maneuvers for long periods. This period has been considered as a ‘transition’ stage and appears to require a look forward toward an altered life approach. Aim The aim of the work was to evaluate the effect of smoking on COVID-19 infection and the effect of COVID-19 infection on smoking propensity. Patients and methods A cross-sectional study was conducted through self-reported surveys. The study was conducted on 101 COVID-19-infected patients aged from 17 to 70 years old, who presented to the Department of Chest of Ain Shams University after approval of the Medical Ethical Committee. The study was conducted through self-reported surveys, which included data on risk factors such as diabetes mellitus, hypertension, ischemic heart disease, chronic obstructive pulmonary disease, interstitial lung disease, and the severity of COVID-19 infection. Results Regarding the associated comorbidities, hypertension was the most frequent disease found in 19.8% of patients followed by diabetes mellitus, which was found in 14.85, then ischemic heart diseases in 9.9%, and then chronic lung disease in 7.92%. Regarding general symptoms of COVID-19, fever was the most common symptom found in 42.57% of patients followed by anosmia in 19.8%, dyspnea in 13.86%, cough in 6.93%, bony aches in 6.93%, loss of taste in 6.94%, and then joint pain, fatigue, chest pain, and vomiting in 0.99% for each. Overall, 17.82% of COVID-19-infected patients required hospital admission, whereas 11.82% required oxygen therapy and 5.94% of patients required ICU admission. Only one COVID-19-infected patient had undergone spirometry after COVID-19. Overall, 47.56% experienced smoking cessation, 45.12% never tried to quit smoking, and 7.32% tried multiple times to quit. Multiple factors have affected smoking habit as follows: marriage has increased smoking in 61.9% of participants, and also work, depression, and happiness have increased smoking in 92.31, 95.12, and 64.63% of participants, respectively. Conclusion COVID-19 pandemic has led to unexpected changes in daily activities and alteration in health behaviors. The effects of smoking on human health are serious and profound. Smoking has increased the severity of COVID-19, symptoms, and hospital admission, especially in persons with multiple comorbidities. In the present study, there was a significant relation between admission to hospital and age, period of smoking, and frequency of smoking. Smoking cessation programs should be conducted for individuals, as they help smokers recognize and cope with problems that come up during quitting.","PeriodicalId":46359,"journal":{"name":"Egyptian Journal of Chest Diseases and Tuberculosis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86977189","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}

If the diagnostic accuracy of CUS for pulmonary tuberculosis (PTB) is similar to that for CUS in the diagnosis of pneumonia, CUS could play an important role in its diagnosis. Aim This study aimed to describe the diagnostic features and use of CUS in TTB and compare CUS findings in PTB versus community-acquired pneumonia (CAP). Patients and methods Consecutive patients presenting with TTB and CAP were enrolled in this study. Computed tomography (CT) chest, CUS, mediastinal US, and abdominal US were performed. CUS lesion pattern in TTB, PTB, and CAP cases were recorded. Results CUS in patients with PTB uniquely and significantly detected pleural gap (28 patients, 27%), fragmented pleura (35 patients, 34%), subpleural fluid collection (three patients, 2.9%), and subpleural nodules (SPN) (97 patients, 95%), which were not detected by CT (P<0.05 for all). Moreover, CUS in patients with PTB uniquely and significantly detected absent sliding sign in a cavitary lesion, pleural gap, and SPNs, which were absent in CUS in CAP (P<0.05 for all) and highly significant more subpleural consolidations when compared with CUS findings in CAP. However, more significant air bronchogram CUS patterns were encountered in patients with CAP than in those with PTB. Conclusion CUS is a complementary tool in assessing TTB.
