Insights
Male gender, hypertension, and diabetes are key risk factors for COVID-19 (Coronavirus disease 2019). This study in Jeddah identified lower lymphocyte and neutrophil counts in patients with SARS-CoV-2 infection.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, presents significant morbidity and mortality.
- While clinical features are documented, COVID-19 risk factors require further elucidation.
- This study aimed to identify risk factors and clinical characteristics of COVID-19 in Jeddah, Saudi Arabia.
Purpose of the Study:
- To characterize the risk factors associated with COVID-19.
- To describe the clinical features of COVID-19 patients.
- To investigate demographic and clinical data for COVID-19 in Jeddah.
Main Methods:
- Retrospective, chart-review, case-control study design.
- Inclusion of patients diagnosed between March 18 and May 18, 2020.
- Analysis of demographic, clinical, radiological, and laboratory data.
Main Results:
- 175 COVID-19 positive cases and 122 controls were analyzed.
- Male gender, hypertension, and diabetes were more prevalent in COVID-19 patients.
- Fever, cough, loss of taste/smell, and pneumonia were associated with positive COVID-19 diagnosis; lower lymphocyte and neutrophil counts observed.
Conclusions:
- Male gender, hypertension, and diabetes are significant risk factors for COVID-19 in Jeddah.
- COVID-19 patients exhibited significantly lower lymphocyte and neutrophil counts.
- Understanding these factors aids in managing and preventing COVID-19 spread.
Background:
Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2), is associated with significant morbidity and mortality. The clinical features of COVID-19 were mentioned in previous studies. However, risk factors for COVID-19 are not fully recognized. The aim of this study is to characterize risk factors and clinical features of COVID-19 disease in Jeddah, Saudi Arabia.
Methods:
A retrospective, chart-review, case-control study was conducted at King Abdulaziz University, Jeddah, Saudi Arabia. Demographic, clinical, radiological, and laboratory data on patients diagnosed between March 18 and May 18, 2020 were collected and analyzed.
Results:
We reviewed medical records on 297 suspected cases of COVID-19. Of these, 175 (59%) tested positive for COVID-19 by polymerase chain reaction (PCR) and considered as cases, while 122 (41%) tested negative and considered as control. COVID-19 positive cases were more likely to be males, and non-health care providers. Hypertension (15%), diabetes (10%) and two or more concurrent comorbidities (54.4%) were more prevalent among COVID-19 patients. Patients presented with fever, cough, and loss of taste/smell were more likely to test positive for COVID-19 (P = 0.001, 0.008, 0.008; respectively). Radiological evidence of pneumonia was associated with confirmed COVID-19 disease (P = 0.001). Shortness of breath and gastrointestinal symptoms were not associated with the risk of COVID-19 at presentation. On admission, white blood cells, neutrophils, lymphocytes, eosinophils, basophils, and platelets were significantly lower among COVID-19 patients compared with controls. Surprisingly, D-Dimer levels were lower among COVID-19 positive patients when compared with controls.
Conclusion:
Male gender, hypertension, and diabetes are the most commonly observed risk factors associated with COVID-19 disease in Jeddah, Saudi Arabia. COVID-19 patient had significantly lower lymphocyte and neutrophil counts.
