Other studies in clinical and laboratory findings
a metanalyses showed that the main clinical manifestations of COVID-19 were fever , cough , and dyspnea (Jiang et al., 2020). in a study with 208 patients, median age was 50.5 years, 51.4% of them were men and 48.6% were women. 7.7% of the patients had pulmonary diseases, 19.7% hypertension, and 6.3% diabetes. In our study, 26.5% of the patients had diabetes, hypertension and Asthma. Among all symptoms, 70.2% and 55.3% were belonged to fever and cough respectively. In compatible, 20.2% cases had decreased white blood cell count, and 29.3% cases had declined lymphocyte count. 74% of them had elevated CRP, and 11.1% had elevated LDH in the present study (Zhang et al., 2020b). In a retrospective cohort study, The mean age of the patients were 59.5 years and 67% patients were male (Shi et al., 2020).In a study, of 138 hospitalized patients, the median age was 56 years and 54.3% were men. Common symptoms were included fever 98.6%, and dry cough 59.4%. Lymphopenia occurred in 70.3% patients. HRCT showed bilateral patchy shadows or ground glass opacity in the lungs of all patients (Wang et al., 2020). In a Meta analysis study, including a total of 50404 patients with 2019-nCoV infection, the incidence of fever was 90.9% , and cough was 70.8%, moreover the incidence of abnormal chest CT was 95.6% (Sun et al., 2020), abnormal HRCT in our study was 88%. In a study in Beijing of 262 patients, the median age of patients was 47.5 and 48.5% of them were men. The most common symptoms at the onset of illness were fever (82.1%), cough (45.8%), dyspnea (6.9%) (Tian et al., 2020) that compatible with our study. In the other study(Zhang et al., 2020a) of 140 hospitalized COVID‐19 cases, a 1:1 ratio of men and women COVID-19 patients was found(50.7%), with a median age of 57.0 . Fever (91.7%), cough (75.0%) were the most common clinical manifestations, whereas hypertension (30.0%) and diabetes mellitus (12.1%) were the most common comorbidities (Zhang et al., 2020a). Bilateral patchy opacity or ground glass (89.6%) was the most common radiological finding. Lymphopenia (75.4%) and eosinopenia (52.9%) were seen in most cases. Eosinopenia with lymphopenia may be an indicator for diagnosis. Allergic diseases, asthma, and COPD are not risk factors for SARS-CoV-2 infection (Zhang et al., 2020a). The most common comorbidities in our study were hypertension, diabetes mellitus and asthma. Also, bilateral multilobar patchy ground glass opacities, bilateral multilobar patchy ground glass opacities and bilateral alveolar consolidations were the most common radiological findings in present study. Another study showed that of 1099 patients, the median age of the patients was 47 years; 41.9% of the patients were female. The common symptoms were fever and cough. Ground-glass opacity was the most common radiologic finding on chest CT (56.4%). 83.2% of the patients had lymphocytopenia. Patients often presented without fever, and many did not have abnormal radiologic findings(Guan et al., 2020). Ground-glass opacity in present study was higher common finding. Similar to our study, lymphocytopenia in COVID-19 patients was seen in the other studies(Surveillances, 2020, Diao et al., 2020).In a metha analysis, for 656 patients, fever 88.7%, cough 57.6% and dyspnea 45.6% were the most prevalent manifestations(Rodriguez-Morales et al., 2020).Of the 99 patients with 2019-nCoV pneumonia, The average age of the patients was 55·5 years, including 67 men and 32 women. 83% of the patients had fever, 82% cough, 31% shortness of breath, and 11% myalgia. According to imaging findings, 75% patients showed bilateral pneumonia, 14% patients showed multiple mottling and ground-glass opacity, and 1% patient had pneumothorax (Chen et al., 2020).Of the 10 cases, the average age was 56.5 years , 60% of the patients were males, Dry cough was the main symptom, followed by fever and fatigue. Chest computed tomography results were nonspecific, mainly with ground-glass attenuation and/or shadow images (Xia et al., 2020). Fever 72%, and cough 83% were common symptoms in a study. 33% of them had an abnormal chest radiograph finding or lung crepitations. Lymphopenia was present in 39% (Young et al., 2020).  A total of 5700 patients were included with median age, 63 years, and 39.7% female. The most common comorbidities were hypertension 56.6%, and diabetes 33.8% (Richardson et al., 2020). In a study, The prevalence of asthma in patients with COVID-19 was 0.9% (Li et al., 2020). During the course of a study 21 COVID-19 positive patients were admitted in , Jaipur, 66.66% of the patients were men and 80.90% were less than 60 years of old. Almost 33.33% patients were asymptomatic and of those who were symptomatic, cough was seen in 85.71% that followed by myalgia (64.28%), fever (78.57%), and dyspnea (28.57%). 14.28 % of the cases had co morbidities in the form of diabetes mellitus, hypertension, hypothyroidism, or coronary artery disease. moreover, 52.38% of the patients had lymphopenia(Bhandari et al., 2020). These patterns in comorbidities and lymphopenia were seen in our study, too.
