RESUMO

Abstract Background: Positive end-expiratory pressure (PEEP) can overcome respiratory changes that occur during pneumoperitoneum application in laparoscopic procedures, but it can also increase intracranial pressure. We investigated PEEP vs. no PEEP application on ultrasound measurement of optic nerve sheath diameter (indirect measure of increased intracranial pressure) in laparoscopic cholecystectomy. Methods: Eighty ASA I-II patients aged between 18 and 60 years scheduled for elective laparoscopic cholecystectomy were included. The study was registered in the Australian New Zealand Clinical Trials (ACTRN12618000771257). Patients were randomly divided into either Group C (control, PEEP not applied), or Group P (PEEP applied at 10 cmH20). Optic nerve sheath diameter, hemodynamic, and respiratory parameters were recorded at six different time points. Ocular ultrasonography was used to measure optic nerve sheath diameter. Results: Peak pressure (PPeak) values were significantly higher in Group P after application of PEEP (p = 0.012). Mean respiratory rate was higher in Group C at all time points after application of pneumoperitoneum (p < 0.05). The mean values of optic nerve sheath diameters measured at all time points were similar between the groups (p > 0.05). The pulmonary dynamic compliance value was significantly higher in group P as long as PEEP was applied (p = 0.001). Conclusions: During laparoscopic cholecystectomy, application of 10 cmH2O PEEP did not induce a significant change in optic nerve sheath diameter (indirect indicator of intracranial pressure) compared to no PEEP application. It would appear that PEEP can be used safely to correct

RESUMO

OBJECTIVE: Although readmission after surgical procedures has been recognized as a new problem, its association with cholecystectomy has not been solved. We aimed to investigate the rate of unplanned readmission after cholecystectomy and to evaluate the reasons and outcomes in these patients. METHODS: All consecutive patients who underwent open and laparoscopic cholecystectomy were retrospectively evaluated. Hospital readmission within the post-operative first 90 days after the procedure was searched. The rate and reasons for hospital readmission were the primary outcomes. RESULTS: There were 601 patients with a mean age of 53.2 ± 12.4 years. The rate of readmission was 6.16%. Obesity (p = 0.001), number of coexisting disease (p = 0.039), conversion to open surgery (p = 0.002), development of intraoperative complications (p < 0.001), use of drain (p = 0.001), and length of hospital stay > 1 day (p = 0.024) were significantly associated with higher readmission rates. Biliary surgical causes were detected in five patients (12.8%). Non-biliary surgical causes were seen in 34 patients (87.2%). Among these, post-operative pain, nausea, and vomiting were the most common diagnoses in 25 (67.6%) and 5 patients (12.8%). CONCLUSION: The readmission rate after cholecystectomy is low. Significant predictive factors may help physicians to be alerted during the discharge of the patients. Post-operative pain, nausea, and vomiting were the most common diagnoses.


OBJETIVO: Aunque el reingreso hospitalario posterior a la cirugía se reconoció como un problema nuevo, su asociación con la colecistectomía no ha sido resuelta. Nuestro objetivo fue investigar la tasa de reingreso al hospital no planificado después de la colecistectomía y evaluar las razones y los resultados en estos pacientes. MÉTODOS: Todos los pacientes consecutivos que se sometieron a colecistectomía abierta y laparoscópica fueron evaluados retrospectivamente. Se investigó el reingreso al hospital dentro de los primeros 90 días postoperatorios. La tasa y las razones de la readmisión hospitalaria fueron los resultados primarios. RESULTADOS: Se examinaron 601 pacientes con una edad media de 53.2 ± 12.4 años. La tasa de reingreso fue del 6.16%. Obesidad (p = 0.001), número de enfermedades coexistentes (p = 0.039), conversión a cirugía abierta (p = 0.002), desarrollo de complicaciones intraoperatorias (p < 0.001), uso de drenaje (p = 0.001) y longitud de estancia hospitalaria > 1 día (p = 0.024) se asociaron significativamente con tasas más altas de reingreso. Se detectaron causas quirúrgicas biliares en cinco pacientes (12.8%). Se observaron causas quirúrgicas no biliares en 34 pacientes (87.2%). Entre estos, el dolor postoperatorio, las náuseas y los vómitos fueron los diagnósticos más comunes en 25 (67.6%) y 5 pacientes (12.8%). CONCLUSIÓN: La tasa de reingreso después de la colecistectomía es baja. Factores predictivos significativos pueden ayudar a los médicos a estar alertas durante el alta de los pacientes. El dolor postoperatorio, las náuseas y los vómitos fueron los diagnósticos más frecuentes.

RESUMO

OBJECTIVE: This study aimed to investigate the effectiveness of dexamethasone in dialysis patients with COVID-19 and whether it predicts mortality. METHODS: This is a comparative cross-sectional study of 113 consecutive patients with COVID-19 with severe pneumonia signs. The patients were divided into two groups according to the use of dexamethasone treatment: group 1 (n=45) included patients who were treated with dexamethasone and group 2 (n=68) who did not receive dexamethasone. RESULTS: The mean age of both groups was 67.0±10.6 and 67.2±13.0 years, respectively (p=0.947). With respect to demographic and laboratory findings, there were no significant differences between the two groups (p>0.05). The hospitalization time of patients in group 1 was longer than that in group 2 (11 [7-17] days vs. 8 [5.3-14] days, p=0.093]. The 28-day survival rate was 54.2% in the group receiving dexamethasone treatment and 79.5% in the group not receiving dexamethasone treatment (p=0.440). CONCLUSION: Dexamethasone did not reduce mortality rates and the requirement for intensive care unit in dialysis patients with COVID-19. Larger prospective randomized clinical trials are required to associate personalized medicine with the corticosteroid treatment to select suitable patients who are more likely to show a benefit.

RESUMO

BACKGROUND: The purpose of this study was to investigate the relation between venous blood gas and chest computerized tomography findings and the clinical conditions of COVID-19 pneumonia. METHODS: A total of 309 patients admitted to the emergency department and subsequently confirmed COVID-19 cases was examined. Patients with pneumonia symptoms, chest computerized tomography scan, venous blood gas findings, and confirmed COVID-19 on reverse transcription-polymerase chain reaction (PCR) were consecutively enrolled. Multiple linear regression was used to predict computerized tomography and blood gas findings by clinical/laboratory data. RESULTS: The median age of patients was 51 (interquartile range 39-66), and 51.5% were male. The mortality rate at the end of follow-up was 18.8%. With respect to survival status of patients pCO2 and HCO3 levels and total computerized tomography score values were found to be higher in the surviving patients (p<0.001 and p=0.003, respectively), whereas pH and lactate levels were higher in patients who died (p=0.022 and p=0.001, respectively). With logistic regression analysis, total tomography score was found to be significantly effective on mortality (p<0.001). The diffuse and random involvement of the lungs had a significant effect on mortality (p<0.001, 95%CI 3.853-38.769, OR 12.222 and p=0.027; 95%CI 1.155-11.640, OR 3.667, respectively). With linear regression analysis, the effect of pH and lactate results were found to have a positive effect on total tomography score (p=0.003 and p<0.001, respectively), whereas pCO2 was found to have a negative effect (p=0.029). CONCLUSION: There was correlation between venous blood gas indices and radiologic scores in COVID-19 patients. Venous blood gas taken in emergency department can be a fast, applicable, minor-invasive, and complementary test in terms of diagnosing COVID-19 pneumonia and predicting the prognosis of disease.

RESUMO

OBJECTIVE: This study aims to investigate and compare the coagulation parameters of coronavirus disease 2019 (COVID-19) patients with mortal and nonmortal conditions. METHODS: In this study, 511 patients diagnosed with COVID-19 were included. Information about 31 deceased and 480 recovered COVID-19 patients was obtained from the hospital information management system and analyzed retrospectively. Whether there was a correlation between coagulation parameters between the mortal and nonmortal patients was analyzed. Descriptive analyses on general characteristics of the study population were performed. Visual (probability plots and histograms) and analytical methods (Kolmogorov-Smirnov and Shapiro-Wilk test) were used to test the normal distribution. Analyses were performed using the SPSS statistical software package. RESULTS: Out of 511 patients, 219 (42.9%) were females and 292 (57.1%) were males. There was no statistically significant difference between males and females in terms of mortality (p=0.521). In total, the median age was 67 (22). The median age was 74 (13) in the nonsurvivor group and 67 (22) in the survivor group, and the difference was statistically significant (p=0.007). The D-dimer, prothrombin time, international normalized ratio, neutrophil, and lymphocyte median age values with p-values, in the recovered and deceased patient groups were: 1070 (2129), 1990 (7513) µg FEU/L, p=0.005; 12.6 (2.10), 13.3 (2.1), p=0.014; 1.17 (0.21), 1.22 (0.19), p=0.028; 5.51 (6.15), 8.54 (7.05), p=0.001; and 0.99 (0.96), 0.64 (0.84), p=0.037, respectively, with statistically significant differences. CONCLUSIONS: As a result of this study, D-dimer, prothrombin time, and international normalized ratio increase were found to be associated with mortality. These parameters need to be closely monitored during the patient follow-up.

RESUMO

OBJECTIVE: The present study compares the cardiac parameters of the survivor and nonsurvivor patients with COVID-19 infection. METHODS: This study was conducted in 379 patients diagnosed with COVID-19 disease. Information of 21 nonsurvivor and 358 survivor patients with COVID-19 was obtained from the hospital information management system and analyzed retrospectively. Relationship between cardiac parameters in patients categorized into the mortal and immortal groups was investigated. RESULTS: Of the total 379 patients involved in this study, 155 (40.9%) were females and 224 (59.1%) were males. No statistically significant difference in mortality was found between females and males (p=0.249). The total median age was 70, the median age in the nonsurvivor group was 74 (35-89), and it was 69.5 (18-96) in the survivor group (p=0.249). The median values of high-sensitivity troponin (hs-Tn), creatine kinase MB form, and especially myoglobin in the survivor and nonsurvivor groups were 25/64.9 (p=0.028), 18/23 (p=0.02), and 105.5/322.4 (p<0.001), and the difference was statistically significant. Comparing mortality, while there was 1 (0.7%) nonsurvivor out of 134 patients in the service unit, there were 20 (8.2%) nonsurvivors out of 245 patients in the intensive care unit. This difference was statistically significant (p=0.003). The cutoff value of myoglobin, which may pose a risk of mortality, was found to be 191.4 µg/L, while it was 45.7 ng/l for hs-Tn and 60.1 U/L for creatine kinase MB. CONCLUSIONS: Advanced age and increased levels of high-sensitivity troponin, creatine kinase MB, and myoglobin were found to be associated with mortality.

RESUMO

BACKGROUND: High-intensity statin (HIS) therapy is widely recommended for secondary prevention after an acute myocardial infarction (AMI). The 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) dyslipidemia guidelines have lowered the target low-density lipoprotein cholesterol (LDL-C) level, which necessitates a more frequent use of nonstatin therapies. OBJECTIVES: The objectives of the study were to investigate the rate of LDL-C target attainment for secondary prevention in AMI patients. METHODS: This retrospective investigation included 1360 patients diagnosed with AMI in a tertiary heart center. Lipid parameters were collected within 24 h of admission and within 1 year after discharge. The medications used were retrieved from medical records, and the lowest LDL-C levels after statin treatment were used to assess the effectiveness of the therapy. LDL-C target attainment was defined according to the 2016 ESC/EAS dyslipidemia guidelines as an LDL-C level of < 70 mg/dL and a ≥ 50% reduction from baseline. In addition, the rate of LDL-C target attainment according to the 2019 fromESC/EAS guidelines was defined as an LDL-C level of < 55 mg/dL and a ≥ 50% reduction baseline. RESULTS: In total, 502 (36.9%) and 247 (18.2%) patients reached the LDL-C targets according to the 2016 and 2019 ESC/EAS guidelines, respectively. The admission LDL-C levels were significantly lower and HIS treatment was used more frequently in patients who subsequently attained the LDL-C goal. Remarkably, 461 (34%) patients failed to reach the LDL-C goals despite HIS treatment. Only 27 (1.9%) patients were prescribed ezetimibe. CONCLUSION: The rate of LDL-C goal attainment in AMI patients was low, which indicates the need for combination statin and non-statin lipid-lowering therapies.

RESUMO

Abstract: Purpose: The objective of this study is to evaluate and compare the microtensile bond strength (μTBS) of four different self-adhesive resin cements to a resin-based ceramic CAD/CAM block, at the baseline, and after subjecting them to 5,000 thermo-cycles.Materials and Methods: Four self-adhesive dual-cured resin cements; G-CEM LinkAce (GC EUROPE, Leuven, Belgium), RelyX U200 (3M ESPE, Seefeld, Germany), Maxcem Elite (Kerr, CA, USA), TheraCem (Bisco, Schaumburg, USA) were applied to Cerasmart CAD/CAM blocks (GC EUROPE, Leuven, Belgium). CAD/CAM blocks were sectioned into sticks and subjected to µTBS tests at 24 hours, and the other half were subjected to tests after 5000 thermo-cycles. The data were tested by one-way variance analysis (p<0.05). Results: The highest bond strength values were observed in TheraCem, followed by G-CEM LinkAce and RelyX U200, respectively (p<0.05). At the baseline, G-CEM LinkAce, RelyX U200, and Maxcem Elite showed statistically similar results. After 5,000 thermal-cycles, a significant decrease was observed in the bond strength values of G-CEM LinkAce (p<0.05). Conclusion: Between the adhesive cements used in the study, TheraCem showed the highest micro-tensile bond strength values both in the baseline (24h) results, and after the 5,000 thermal- cycle aging procedures.


Resumen: Propósito: Evaluar y comparar la resistencia adhesiva microtensil (μTBS) de cuatro cementos de resina autoadhesivos diferentes con un bloque CAD/CAM de cerámica a base de resina, antes y después de 5.000 ciclos de termociclado. Materiales y métodos: cuatro cementos de resina de doble curado autoadhesivos; G-CEM LinkAce (GC EUROPE, Lovaina, Bélgica), RelyX U200 (3M ESPE, Seefeld, Alemania), Maxcem Elite (Kerr, CA, EE. UU.), TheraCem (Bisco, Schaumburg, EE. UU.) fueron aplicados a bloques Cerasmart CAD/CAM (GC EUROPE, Lovaina, Bélgica). Los bloques CAD/CAM se seccionaron en barras y se sometieron a pruebas µTBS a las 24 horas, y la otra mitad se sometió a pruebas después de 5000 ciclos térmicos. Los datos fueron probados por análisis de varianza unidireccional (p<0.05). Resultados: Los valores más altos de fuerza de unión se observaron en TheraCem, seguido de G-CEM LinkAce y RelyX U200, respectivamente (p<0.05). En la línea de base, G-CEM LinkAce, RelyX U200, Maxcem Elite mostró resultados estadísticamente similares. Después de 5.000 procesos de ciclo térmico, se observó una disminución significativa en los valores de resistencia de la unión de G-CEM LinkAce (p<0.05). Conclusión: entre los cementos adhesivos utilizados en el estudio, TheraCem mostró los valores más altos de resistencia de la unión micro-extensible tanto en la línea de base (24 h) como después de 5,000 procedimientos de envejecimiento térmico.

CONCLUSION: There was correlation between venous blood gas indices and radiologic scores in COVID-19 patients. Venous blood gas taken in emergency department can be a fast, applicable, minor-invasive, and complementary test in terms of diagnosing COVID-19 pneumonia and predicting the prognosis of disease.

OBJECTIVE: Good knowledge of the coronavirus disease 2019 (COVID-19) among healthcare workers is essential for keeping health systems active and controlling the outbreak. We aimed to investigate the knowledge and attitudes of Emergency Medical Service (EMS) employees who fight COVID-19 at the forefront. METHODS: A total of 400 EMS workers (doctors, nurses, emergency medical technicians, paramedics, and ambulance drivers) were included in this study. Knowledge, attitude, and preventive behaviors for COVID-19 were evaluated using an online questionnaire. RESULTS: A total of 275 EMS workers participated in the study with a response rate of 68.8%. The respondents reported that their highest common sources of knowledge about COVID-19 were social media and television (n=240, 88%). Overall, > 96% of the participants had adequate knowledge about the transmission routes of COVID-19. Among the respondents, 36% of them were unaware of the correct hand washing or scrubbing technique. In addition, 78% of the participants had poor knowledge about floor and surface disinfection. The majority of the participants exhibited inaccurate attitudes toward the use of personal preventive equipment. More than half of EMS workers (52%) agreed that a surgical mask is not enough during the procedures that do not generate aerosol. Moreover, a significant proportion of the participants (66%) perceived that a N95 mask is required. CONCLUSIONS: As a consequence, although emergency workers have sufficient basic knowledge about COVID-19, there is a need for postgraduate training in many subjects.

RESUMO OBJETIVO: Um bom conhecimento sobre a doença por coronavírus 2019 (COVID-19) entre profissionais de saúde é essencial para manter os sistemas de saúde ativos e controlar o surto. Nosso objetivo foi investigar o conhecimento e as atitudes dos funcionários do serviço médico de emergência (EMS) que lutam com o COVID-19 na vanguarda. MÉTODOS: Um total de 400 trabalhadores do SME (médicos, enfermeiros, técnico de emergência médica, paramédicos e motoristas de ambulância) foram incluídos neste estudo. Conhecimento, atitude e comportamentos preventivos para COVID-19 foram avaliados usando um questionário on-line. RESULTADOS: Um total de 275 trabalhadores do SME participou do estudo com uma taxa de resposta de 68,8%. Os entrevistados relataram que as maiores fontes comuns de conhecimento sobre COVID-19 foram as mídias sociais e a televisão (n = 240, 88%). No geral,> 96% dos participantes tinham conhecimento adequado sobre as rotas de transmissão do COVID-19. Entre os entrevistados, 36% deles desconheciam a técnica correta de lavar ou esfregar as mãos. Além disso, 78% dos participantes tinham pouco conhecimento sobre desinfecção de pisos e superfícies. A maioria dos participantes exibiu atitudes imprecisas em relação ao uso de equipamentos preventivos pessoais. Mais da metade dos trabalhadores do SME (52%) concordou que a máscara cirúrgica não é suficiente durante os procedimentos que não geram aerossol. Além disso, uma proporção significativa dos participantes (66%) percebeu que a máscara N95 é necessária. CONCLUSÕES: Como conseqüência, embora os trabalhadores de emergência tenham conhecimento básico suficiente sobre o COVID-19, há necessidade de treinamento de pós-graduação em muitas disciplinas.

RESUMO

INTRODUCTION: This study aims to determine the incidence of de novo nephritic syndrome (NS) in COVID-19 patients and identify its associated factors. METHODS: All ward patients with COVID-19 pneumonia were investigated. After determining the inclusion and exclusion criteria, the study population was identified. The urine dipstick test and urine protein creatinine ratio (UPCR) measurements were performed. Patients with de novo NS findings, nasopharyngeal swab, and urine RT-PCR tests were performed simultaneously. RESULTS: This descriptive cross-sectional study was conducted with 21 patients with COVID-19. The mean age of the patients was 42.2±8.8 years, and 71.4% of them were male. The mean duration of follow-up was 28.4±9.3 days. The urine RT-PCR test was positive in one patient (4.8%). Improvements were observed in hematuria by 71.4%, and proteinuria by 85.7% at the end of the follow-up. A significant decrease in the measured UPCR was found in comparison to the baseline(P=0.000). Also, improvements were recorded in the complete blood counts, inflammatory parameters, ferritin, and coagulation tests, compared to the baseline. There was a positive correlation between baseline UPCR and ferritin, and a negative correlation between baseline UPCR and sodium values. CONCLUSION: COVID-19-induced de novo nephritic syndrome may occur mainly due to tubulointerstitial involvement and often results in spontaneous remission. However, why these findings were not present in all patients who had no comorbidities is not clear.

RESUMO

OBJECTIVE: Cellulite infection is a non-necrotizing inflammation of the skin and subcutaneous tissue and is one of the most common reasons for admission to hospital. This retrospective study aimed to investigate the Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), and Lymphocyte to Monocyte Ratio (LMR) in patients with cellulitis. METHODS: In our study, we retrospectively analyzed 96 patients with cellulitis and 98 age- and sex-matched healthy controls. The study and control groups were compared regarding NLR, PLR, and LMR.0.001). When patients with cellulitis were divided into two groups, i.e., ≥65 years and <65 years, a statistically significant difference was noted in the NLR and LMR values (p < 0.05). In the ROC curve analysis, NLR had the highest discriminative power in distinguishing between cellulitis and healthy controls (AUC = 0.950, 95% CI: 0.920-0.979, p < 0.001; 91.6% sensitivity and 89.8% specificity). CONCLUSION: NLR was significantly higher in differentiating cellulite and in patients older than 65 years. Larger, prospective studies are required to determine its usefulness in assessing differential diagnosis and prognosis in cellulitis patients.

RESUMO

BACKGROUND: Healthcare personnel are at risk of becoming infected while taking upper and/or lower respiratory tract specimens. Therefore, there is a need for sampling methods that do not risk infecting them. In this study, we aimed to compare the saliva and Oro-Nasopharyngeal Swab (ONS) sampling methods. METHODS: Patients were divided into three groups. Group 1 included patients whose diagnosis of COVID-19 was confirmed by polymerase chain reaction (PCR). Group 2 included patients with COVID-19 compatible findings in lung computed tomography (CT), but with a negative PCR. Group 3 included patients who presented to the emergency department with COVID-19 compatible complaints but had normal CT. Saliva and ONS samples were taken on the third day of hospitalization in groups 1 and 2, whereas in group 3, they were taken at the time of admission to the hospital. RESULTS: A total of 64 patients were included in the study. The average age was 51.04 ± 17.9 years, and 37 (57.8%) were male. SARS-CoV-2 was detected in 27 (42.2%) patients' saliva samples. While the sensitivity and positive predictive value of saliva samples were 85.2%, specificity and negative predictive value were 89.2%. The value of kappa was in substantial agreement (0.744), and it was found statistically significant (<0.001). CONCLUSIONS: Saliva samples can be used instead of ONS samples in detecting SARS-CoV-2. Investigating SARS-CoV-2 with saliva is cheaper, easier for the patient and overall, and, most importantly, it poses much less risk of SARS-CoV-2 contamination to healthcare personnel.

RESUMO

BACKGROUND: Easily accessible, inexpensive, and widely used laboratory tests that demonstrate the severity of COVID-19 are important. Therefore, in this study, we aimed to investigate the relationship between mortality in COVID-19 and platelet count, Mean Platelet Volume (MPV), and platelet distribution width. METHODS: In total, 215 COVID-19 patients were included in this study. The patients were divided into two groups. Patients with room air oxygen saturation < 90% were considered as severe COVID-19, and patients with ≥90% were considered moderate COVID-19. Patient medical records and the electronic patient data monitoring system were examined retrospectively. Analyses were performed using the SPSS statistical software. A p-value <0.05 was considered significant. RESULTS: The patients' mean age was 64,32 ± 16,07 years. According to oxygen saturation, 81 patients had moderate and 134 had severe COVID-19. Our findings revealed that oxygen saturation at admission and the MPV difference between the first and third days of hospitalization were significant parameters in COVID-19 patients for predicting mortality. While mortality was 8.4 times higher in patients who had oxygen saturation under 90 % at hospital admission, 1 unit increase in MPV increased mortality 1.76 times. CONCLUSION: In addition to the lung capacity of patients, the mean platelet volume may be used as an auxiliary test in predicting the mortality in COVID-19 patients.

RESUMO

INTRODUCTION: This study aims to evaluate changes in hematological parameters after the follow-up of patients who received treatment with favipiravir due to COVID-19 infections. METHODS: Sixty-two cases receiving favipiravir treatment for at least five days due to COVID-19 infection were evaluated retrospectively. Parameters including age, gender, nasopharyngeal swab positivity, and chronic diseases were analyzed. Hematologic parameters were analyzed before and after the treatment. RESULTS: The mean age of the patients receiving treatment with favipiravir was 63.7±12.3 years. Nasopharyngeal swab positivity was detected in 67.7%. The most common comorbid conditions detected in patients were hypertension in 25 cases (40.3%) and diabetes in 16 cases (25.8%). In the statistical analysis of the hematological parameters before and after treatment with favipiravir, WBC, PT-PTT-INR levels were found to be unaffected; the mean RBC was found to have decreased from 4.33 ± 0.58 M/uL to 4.16 ± 0.54 M/uL (p:0.003); the median hemoglobin level was found to have decreased from 12.3 g/dl to 11.9 g/dl (p:0.041); the hematocrit level decreased from 38.1% ± 4.8 to 36.9% ± 4.2 (p:0.026); the median neutrophil count decreased from 4.57 K/uL to 3.85 K/uL (p:0.001); the mean lymphocyte count increased from 1.22 ± 0.53 K/uL to 1.84 ± 1.19 K/uL (p:0.000); and the mean platelet count increased from 244.1 ± 85.1 K/uL to 281.9 ± 103.3 K/uL (p:0.005). CONCLUSION: We concluded that the pathological effect of treatment with favipiravir on the hematologic system was the suppression in the erythrocyte series, and there were no adverse effects in other hematologic parameters.
