Suspected SARS-CoV-2 infection with fever and coronary heart disease:A case report

BACKGROUND The coronavirus disease 2019(COVID-19)is an emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Suspected cases accounted for a large proportion in the early stage of the COVID-19 outbreak.The deviation of the nucleic acid test by throat swab(the current gold standard of COVID-19)caused by variation in sampling techniques and reagent kits and coupled with nonspecific clinical manifestations make confirmation of the suspected cases difficult.Proper management of the suspected cases of COVID-19 is crucial for disease control.CASE SUMMARY A 65-year-old male presented with fever,lymphopenia,and chest computed tomography(CT)images similar to COVID-19 after percutaneous coronary intervention.The patient was diagnosed as having bacterial pneumonia with cardiogenic pulmonary edema instead of COVID-19.This was based on four negative results for throat swab detection of SARS-CoV-2 nucleic acid using reverse transcriptase-polymerase chain reaction assay and one negative result for serological antibody of SARS-CoV-2 with the serological assay.Additionally,the distribution of ground-glass opacities and thickened blood vessels from the CT images differed from COVID-19 features,which further supported the exclusion of COVID-19.CONCLUSION Distinguishing COVID-19 patients from those with bacterial pneumonia with cardiogenic pulmonary edema can be difficult.Therefore,it requires serious identification.

Human Immunodeficiency Virus and Immunological Profiles among Suspected Tuberculosis Cases in Mombasa County, Kenya

Background: Human immunodeficiency virus (HIV) is a major public health concern and cause of death globally including Kenya. HIV infection is characterised by CD4+ lymphocyte depletion manifested through the loss of the immune response capacity. Aim: This study aimed to determine the prevalence of HIV infection and CD4+T cell counts among suspected tuberculosis (TB) cases seeking healthcare at TB clinics in Mombasa County, Kenya. Study Design: Hospital and laboratory based cross-sectional study was carried between May 2011 and November 2013 in Coast General Referral Hospital, Tudor, Port-Reitz, Mlaleo, Likoni and Mikandani districts and sub-districts hospitals. Methodology: A total of 500 suspected TB cases (271 males and 229 females) were screened for HIV infection using Trinity Biotech Uni-GoldTM test and positives confirmed with the enzyme- linked immunosorbent assay. CD4+ and CD8+T cells were analyzed using a BD FACS Count flow cytometer. A questionnaire was used to collect demographic data of the participants. Results: In total, 127 (25.4%) of the suspects were HIV infected 55.1% females and 44.9% males. Females were significantly affected than males (OR = 0.78;95% CI: 0.44 - 1.37;p = 0.042). The majority (36.2%) of the HIV cases were in the 25 - 34 years age group followed by the 35 - 44 (33.9%), 45 - 54 (16.5%) and 18 - 24 (7.1%) age groups, respectively. Widowed (AOR = 6.14;95% CI: 1.53 - 20.54;p < 0.033), alcohol (AOR = 2.83;95% CI: 1.71 - 4.87;p < 0.001) and condom use (AOR = 2.31;95% CI: 1.62 = 4.71;p < 0.002) were risk factors associated with HIV infection. The mean CD4 cell count was 333.27 ± 150.59 cells/mm3 and it was higher in males (343.05 ± 149.33 cells/mm3) than females (325.93 ± 152.92 cells). The mean values of white blood cells (5.9 ± 2.42) × 109/l), packed cell value (34.1% ± 4.3%), platelets (195.16 ± 88.7) × 109/l and erythrocyte sedimentation rate (102.0 ± 17.4 mm/hr) were significantly lower than the control group (p < 0.05). Conclusion: The prevalence of HIV infection among suspected TB cases was 25.4% which was higher than the current national average HIV prevalence of 6.9%. Lower CD4+ lymphocyte count was found to be the only predicting factor for HIV. There was a significant relationship between CD4/ESR and HIV infection.

Primary stratification and identification of suspected corona virus disease 2019(COVID-19) from clinical perspective by a simple scoring proposal

In this Commentary,we would like to comment on the article titled"A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV)infected pneumonia(standard version)"as a featured article in Military Medical Research.In the guideline,except for"confirmed cases","suspected cases","close contact"and"suspicious exposure"were defined by clinical perspective based on epidemiological risk,clinical symptoms and auxiliary examination.Combined with our experience,we introduced a simple scoring proposal additionally based on not only CT imaging as strongly recommended by the guideline but also blood routine test,especially for primary screening of such patients in the out-patient department.

Expert Consensus by Qilu Hospital of Shandong University on the diagnosis,management,and treatment of suspected COVID-19 cases(English version)

We devised a protocol to establish a standardized method of screening,diagnosing,and managing suspected cases of coronavirus disease(COVID-19)and to enhance the management of COVID-19 suspected cases.The protocol that included diagnostic criteria,preventive measures,and control measures against COVID-19 was developed based on new evidence regarding the epidemiological and clinical characteristics of COVID-19.A consensus document was subsequently formulated.The consensus focused on the clinical management of patients with suspected fever and reviewed the procedure for undergoing severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)nucleic acid testing.This consensus will contribute to the ongoing efforts worldwide for the prevention and control of COVID-19.
