Abstract
Background

Coronavirus disease 19 (COVID-19) is a recently described infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Iran was the first country where the SARS-Cov-2 was detected in the Middle East. In the current study, we aimed to evaluate the clinical, radiological and laboratory findings in hospitalized COVID-19 confirmed cases in Iran.

Methods

The clinical manifestations, radiological data, laboratory findings, and the underlying diseases of the patients with COVID-19 were obtained from electronic medical records. Next, this information was compared in discharged and dead patients.

Results

Overall, 4028 patients with COVID-19 including 3088 discharged, 778 dead, and 162 still hospitalized patients were enrolled in this study. The highest percentage of people who recovered (55%) was between 30 and 60 years old and the highest percentage of deaths (74.4%) was more than 60 years old. Based on demographic data, 50.05% were female and 49.95% were male. Clinical evaluations revealed that dyspnea (56.9%), cough (31.4%) and fever (17.8%) were the most manifestations. Comorbidities were significantly higher in the dead group. Laboratory analysis revealed abnormalities in lymphocyte count (LYM), erythrocyte sedimentation rate (ESR), and inflammatory biomarkers such as C-reactive protein (CRP). The most prevalent computed tomography (CT) scan data were ground-glass opacity (GGO) (30.5%) and consolidation (9.4%).

Conclusions

Laboratory parameters and clinical and radiological findings help to evaluate the follow-up of the disease in patients. Age and comorbidities are factors that predispose people to COVID-19. Further research is needed to evaluate the effects of various factors on the progression of COVID-19 infection.

Resumen
Antecedentes

La enfermedad por coronavirus de 19 (COVID-19) es una enfermedad infecciosa recientemente descrita causada por el síndrome respiratorio agudo severo por coronavirus 2 (SARS-CoV-2). Irán fue el primer país de Oriente Medio donde se detectó SARS-Cov-2. En el estudio actual, nuestro objetivo fue evaluar los hallazgos clínicos, radiológicos y de laboratorio en pacientes hospitalizados con confirmación de COVID-19 en Irán.

Métodos

Se obtuvieron las manifestaciones clínicas, los datos radiológicos, los hallazgos de laboratorio y las enfermedades subyacentes de los registros clínicos electrónicos. Seguidamente, se comparó esta información con los pacientes dados de alta y fallecidos.

Resultados

A nivel global, se incluyó en este estudio a 4.028 pacientes con COVID-19, de los cuales 3.088 habían recibido el alta, 778 habían fallecido, y 162 seguían hospitalizados. El mayor porcentaje de recuperaciones (55%) se produjo entre las personas de 30 a 60 años, y el mayor porcentaje de muertes (74,4%) se dio en los mayores de 60 años. Sobre la base de los datos demográficos, el 50,05% fueron mujeres y el 49,95% varones. Las evaluaciones clínicas revelaron que la disnea (56,9%), la tos (31,4%) y la fiebre (17,8%) fueron las manifestaciones más prevalentes. Las comorbilidades fueron significativamente más elevadas en el grupo de fallecidos. Las analíticas revelaron anomalías en cuanto a recuento linfocitario, tasa de sedimentación eritrocitaria (ESR), y biomarcadores inflamatorios tales como proteína C reactiva (PCR). Los datos procedentes de la tomografía computarizada (TC) fueron opacidad en vidrio esmerilado (GGO) (30,5%) y consolidación (9,4%).

Conclusiones

Los parámetros de laboratorio y los hallazgos clínicos y radiológicos ayudan a evaluar el seguimiento de la enfermedad en los pacientes. La edad y las comorbilidades son factores que predisponen a las personas a la COVID-19. Es necesaria más investigación para evaluar los efectos de los diversos factores en la progresión de la infección por COVID-19.
