The effectiveness of dexamethasone on the prognosis of dialysis patients with severe COVID-19

SUMMARY 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.

Evaluation of cardiac parameters between survivors and nonsurvivors of COVID-19 patients

SUMMARY 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.

Evaluation of coagulation parameters: Coronavirus disease 2019 (COVID-19) between survivors and nonsurvivors

SUMMARY 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.

Correlation between venous blood gas indices and radiological involvements of COVID-19 patients at first admission to emergency department

SUMMARY 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.

Is the COVID-19 disease associated with de novo nephritic syndrome?

SUMMARY 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 INTRODUÇÃO: Este estudo tem como objetivo determinar a incidência da síndrome nefrítica de novo (SN) em pacientes com COVID-19 e identificar os fatores associados. MÉTODOS: Todos os pacientes da enfermaria com pneumonia por COVID-19 foram investigados. Após a determinação dos critérios de inclusão e exclusão, a população do estudo foi identificada. Foram realizadas medições do teste da vareta da urina e da razão da creatinina das proteínas na urina (UPCR). RESULTADOS: Este estudo transversal descritivo foi realizado com 21 pacientes com COVID-19. A idade média dos pacientes foi de 42,2±8,8 anos e 71,4% dos pacientes eram do sexo masculino. A duração média do seguimento foi de 28,4±9,3 dias. O teste de RT-PCR na urina foi positivo em um paciente (4,8%). Houve melhorias observadas na hematúria em 71,4% e na proteinúria em 85,7% no final do acompanhamento. E uma diminuição significativa na UPCR medida em comparação à linha de base (p=0,000). Além disso, foram registradas melhorias nas contagens sanguíneas completas, nos parâmetros inflamatórios, nos testes de ferritina e de coagulação, comparados aos valores basais. Houve correlação positiva entre UPCR basal e ferritina, e correlação negativa entre os valores basais de UPCR e sódio. CONCLUSÃO: A síndrome nefrítica de novo induzida por COVID-19 pode ocorrer principalmente devido ao envolvimento túbulo-intersticial e frequentemente resulta em remissão espontânea. No entanto, a questão de por que esses achados não se apresentaram em todos os pacientes que não apresentavam condição comórbida não é clara.

Evaluation of neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, and lymphocyte to monocyte ratio in patients with cellulitis

SUMMARY 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 OBJETIVO A celulite infecciosa é uma inflamação não necrotizante da pele e do tecido subcutâneo e uma das causas mais comuns para internação. O objetivo deste estudo retrospectivo foi investigar as relações Neutrófilo/Linfócito (RNL), Plaqueta/Linfócito (RPL) e Linfócito/Monócito (RLM) em pacientes com celulite. MÉTODOS Nós analisamos, retrospectivamente, 96 pacientes com celulite e 98 controles saudáveis equivalentes em sexo e idade. Os grupos foram comparados quanto a RNL, RPL e RLM. RESULTADOS Os valores de RPL e RNL do grupo com celulite foram significativamente mais elevados do que os do grupo de controle (p < 0,001). Após dividir os pacientes com celulite em dois grupos, ≥65 anos e <65 anos, uma diferença estatisticamente significativa foi observada nos valores de RNL e RLM (p < 0,05). Na análise da curva ROC, a RNL apresentou o maior poder de discriminação para distinguir entre pacientes com celulite e controles saudáveis (AUC = 0,950, 95% CI: 0,920 - 0,979; p < 0,001; 91,6% de sensibilidade e 89,8% de especificidade). CONCLUSÃO O valor de RNL foi significativamente maior para a diferenciação de pacientes com celulite e pacientes com mais de 65 anos. Estudos prospectivos maiores são necessários para determinar a sua utilidade na avaliação de diagnósticos diferenciais e prognósticos em pacientes com celulite.

Effect of COVID-19 on platelet count and its indices

SUMMARY 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 OBJETIVO Testes laboratoriais de fácil acesso, baixo custo e amplamente utilizados capazes de demonstrar a gravidade da COVID-19 são importantes. Portanto, neste estudo, o nosso objetivo foi investigar a relação entre a mortalidade na COVID-19 e a contagem de plaquetas, volume plaquetário médio (VMP) e largura de distribuição de plaquetas. MÉTODOS No total, 215 pacientes com COVID-19 foram incluídos no estudo. Os pacientes foram divididos em dois grupos. Pacientes com saturação de oxigênio < 90% em ar ambiente foram considerados casos graves de COVID-19 e pacientes com valores ≥90% foram considerados casos moderados. Os registros médicos dos pacientes e o sistema eletrônico de monitoramento de dados de pacientes foram analisados retrospectivamente. As análises foram realizadas utilizando o software estatístico SPSS. Um valor de p <0,05 foi considerado significativo. RESULTADOS A média de idade dos pacientes foi de 64,32 ± 16,07 anos. Com base na saturação de oxigênio, 81 pacientes eram casos moderados e 134 tinham COVID-19 grave. Nosso estudo revelou que a saturação de oxigênio no momento da internação e a diferença nos valores de VPM entre o primeiro e terceiro dia de internação foram parâmetros significativos para predizer mortalidade de pacientes com COVID-19. A mortalidade foi 8,4 vezes maior nos pacientes com saturação abaixo de 90% no momento da internação, mas um aumento de apenas 1 unidade no valor de VPM aumentou a mortalidade 1,76 vezes. CONCLUSÃO Além da capacidade pulmonar dos pacientes, o volume plaquetário médio pode ser utilizado como um teste auxiliar para prever a mortalidade de pacientes com COVID-19.

Comparison of saliva and oro-nasopharyngeal swab sample in the molecular diagnosis of COVID-19

SUMMARY 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 OBJETIVO Funcionários da saúde correm risco de infecção ao coletar amostras do trato superior e/ou inferior. Portanto, existe a necessidade de métodos de coleta de amostras que não representem um risco de infecção. Neste estudo, nosso objetivo foi comparar as métodos de coleta de saliva e swab de naso e orofaringe (ONS). MÉTODOS Os pacientes foram divididos em três grupos. O Grupo 1 incluiu pacientes cujo diagnóstico de COVID-19 foi confirmado por reação em cadeia da polimerase (PCR). O Grupo 2 incluiu pacientes com achados compatíveis com COVID-19 em exames de tomografia computadorizada (TC), mas com PCR negativo. O Grupo 3 incluiu pacientes que compareceram ao departamento de emergência com queixas compatíveis com COVID-19, mas TC normal. Amostras de saliva e ONS foram coletadas no terceiro dia de internação, nos Grupos 1 e 2, já no Grupo 3, foram coletadas no momento da internação. RESULTADOS Um total de 64 pacientes foram incluídos no estudo. A média de idade foi de 51,04 ± 17,9 anos, e 37 (57,8%) eram do sexo masculino. SARS-CoV-2 foi detectado em 27 (42,2%) amostras de saliva dos pacientes. A sensibilidade e valor preditivo positivo foi de 85,2% nas amostras de saliva, já a especificidade e o valor preditivo negativo foi 89,2%. O valor de Kappa estava substancialmente de acordo (0,744) e era estatisticamente significante (<0,001). CONCLUSÃO Amostras de saliva podem ser usada em vez de ONS na detecção de SARS-CoV-2. O uso de amostras de saliva para detecção de SARS-CoV-2 é mais barato, mais fácil para o paciente e em geral e, mais importante, representa um risco muito menor de contaminação de SARS-CoV-2 para os profissionais da saúde.

Impact of antihypertensive agents on clinical course and in-hospital mortality: analysis of 169 hypertensive patients hospitalized for COVID-19

SUMMARY OBJECTIVE Coronavirus disease 2019 (COVID-19) is an emerging health threat caused by a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). Previous studies have noted hypertension is associated with increased mortality due to COVID-19; however, it is not clear whether the increased risk is due to hypertension itself or antihypertensive agents. We aimed to evaluate the impact of antihypertensive agents on the clinical outcomes of hypertensive patients with COVID-19. METHODS Our study included 169 consecutive hypertensive patients hospitalized due to COVID-19 between March 20 and April 10, 2020. The demographic characteristics, clinical data, and type of antihypertensive agents being used were reviewed. RESULTS The mean age of patients was 65.8±11.7 years.30 patients(17.7%) died during hospitalization. A total of 142 patients(84%) were using angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs), 91 (53.8%) were using diuretics, 69 (40.8%) were using calcium channel blockers (CCBs), 66 (39.1%) were using beta-blockers, 12 (7.1%) were using alpha-blockers, and 5 (2.9%) were using mineralocorticoid receptor antagonists (MRAs). There was no significant difference between survivors and non-survivors based on the type of antihypertensive agents being used. Binary logistic regression analysis showed that the type of the antihypertensive agent being used had no effect on mortality [OR=0.527 (0.130-2.138), p=0.370 for ACEIs/ARBs; OR=0.731 (0.296-1.808), p=0.498 for CCBs; OR=0.673 (0.254-1.782), p=0.425 for diuretics; OR=1.846 (0.688-4.950), p=0.223 for beta-blockers; OR=0.389 (0.089-1.695), p=0.208 for alpha-blockers; and OR=1.372 (0.107-17.639), p=0.808 for MRAs]. CONCLUSION The type of antihypertensive agent being used had no effect on the clinical course and mortality in hypertensive patients with COVID-19. The use of these agents should be maintained for the treatment of hypertension during hospitalization.

RESUMO OBJETIVO A doença de coronavírus 2019 (COVID-19) é uma ameaça emergente à saúde causada por um novo coronavírus denominado síndrome respiratória aguda grave coronavírus 2 (Sars-COV-2). Estudos anteriores observaram que a hipertensão está associada a um aumento da mortalidade devido ao COVID-19, no entanto, não está claro se o aumento do risco pertence à própria hipertensão ou a agentes anti-hipertensivos. Nosso objetivo foi avaliar o impacto de agentes anti-hipertensivos nos resultados clínicos em pacientes hipertensos com COVID-19. MÉTODOS Nosso estudo incluiu 169 hipertensos consecutivos internados por COVID-19 entre 20 de março e 10 de abril de 2020. As características demográficas, dados clínicos e o tipo de anti-hipertensivos em uso foram revistos. RESULTADOS A idade média dos pacientes foi de 65,8±11,7 anos. Trinta pacientes (17,7%) faleceram durante a internação. Cento e quarenta e dois pacientes (84%) usavam inibidores da enzima de conversão da angiotensina (ACEIs) ou bloqueadores dos receptores da angiotensina II (ARBs), 91 (53,8%) usavam diuréticos, 69 (40,8%) usavam bloqueadores dos canais de cálcio (CCBs), 66 (39,1%) usavam betabloqueadores, 12 (7,1%) usavam bloqueadores alpha e cinco (2,9%) usavam antagonistas dos receptores de mineralocorticoides (MRAs). Não houve diferença significativa entre sobreviventes e não sobreviventes com base no tipo de agentes anti-hipertensivos em uso. A análise de regressão logística binária mostrou que o tipo de agente anti-hipertensivo utilizado não teve efeito na mortalidade (OR=0,527 (0,130-2,138), p=0,370 para ACEIs/ARB; OR=0,731 (0,296-1,808), p=0,498 para CCBs; OR=0,673 (0,254-1,782), p=0,425 para diuréticos; OR=1,846 (0,688-4,950), p=0,223 para bloqueadores beta; OR=0,389 (0,089-1,695), p=0,208 para bloqueadores alpha e OR=1,372 (0,107-17,639), p=0,808 para MRAs). CONCLUSÃO O tipo de agente anti-hipertensivo utilizado não teve efeito no curso clínico e na mortalidade em pacientes hipertensos com COVID-19. O uso desses agentes deve ser mantido no tratamento da hipertensão durante a hospitalização.

The effects of favipiravir on hematological parameters of covid-19 patients

SUMMARY 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.

RESUMO INTRODUÇÃO Este estudo tem como objetivo avaliar as alterações nos parâmetros hematológicos após o acompanhamento de pacientes que receberam tratamento com favipiravir devido à infecção por Covid-19. MÉTODOS Sessenta e dois casos em tratamento com favipiravir por pelo menos cinco dias devido à infecção por Covid-19 foram avaliados retrospectivamente. Parâmetros como idade, sexo, positividade do swab nasofaríngeo e doenças crônicas foram analisados. Os parâmetros hematológicos foram analisados antes e após o tratamento. RESULTADOS A idade média dos pacientes que receberam tratamento com favipiravir foi de 63,7±12,3 anos. A positividade do swab nasofaríngeo foi detectada em 67,7%. As condições comórbidas mais comuns detectadas nos pacientes foram hipertensão em 25 casos (40,3%) e diabetes em 16 casos (25,8%). Na análise estatística dos parâmetros hematológicos antes e após o tratamento com favipiravir, os níveis de leucócitos, PT-PTT-INR não foram afetados. Verificou-se que o RBC médio diminuiu de 4,33±0,58 M/uL para 4,16±0,54 M/uL (p=0,003); o nível médio de hemoglobina foi reduzido de 12,3 g/dl para 11,9 g/dl (p=0,041); o nível de hematócrito diminuiu de 38,1%±4,8 para 36,9%±4,2 (p=0,026); a contagem mediana de neutrófilos diminuiu de 4,57 K/uL para 3,85 K/uL (p=0,001); a contagem média de linfócitos aumentou de 1,22±0,53 K/uL para 1,84±1,19 K/uL (p=0,000); a contagem média de plaquetas aumentou de 244,1±85,1 K/uL para 281,9±103,3 K/uL (p=0,005). CONCLUSÃO Concluiu-se que o efeito patológico do tratamento com favipiravir no sistema hematológico foi a supressão na série eritrocitária e que não houve efeitos adversos em outros parâmetros hematológicos.

High ferritin and myoglobin level in legionella pneumonia: A case report and review of literature.

Legionella pneumophila is a cause of both community- and hospital-acquired pneumonia and might cause high morbidity and mortality. Therefore, early diagnosis and treatment with appropriate antibiotics is crucial. Many clinical and laboratory abnormalities can be observed in the course of Legionella pneumonia. In this study, we aimed to present simultaneously increased serum ferritin and myoglobin level in a legionella case with reference to the relevant literature.

Pedro pons' singn as a brucellosis complication.

Brucellosis is one of the most important zoonotic diseases. Several complications may be seen during its clinical coures. Here, we describe a patient who presented with complaints of fatigue, malaise, and intensive lumbar pain. He had been suffering from these complaints for nearly 1 month. It was learned that he lived in rural area, made and ate his own cheese. The Rose Bengal test was positive and Brucella standard tube agglutination was positive at 1/320 titer. Pedro Pons' sings, an osteoarticular complication of brucellosis, was revealed with the aid of radiologic imaging. Osteoarticular involvement is common in the course of brucellosis. Deformation in vertebrae formerly known as pedro pons' sign should be thought in brucellosis patients suffering from lumbar pain.

Antituberculosis drug resistance and associated risk factors in the European section of Turkey.

BACKGROUND: We carried out this study in order to establish the prevalence of antituberculosis drug resistance in Mycobacterium tuberculosis strains and to determine risk factors for the development of resistance in Trakya region of Turkey. METHODS: Pattern of drug resistance in 214 M. tuberculosis isolates from patients with tuberculosis treated at the regional tuberculosis dispensaries were included in the study. RESULTS: Isolates of 105 (49.1%) were resistant to only one drug, and 62 (29.0%) were resistant to more than one drug. The total resistance rates to streptomycin, isoniazid, rifampicin, ethambutol and isoniazid + rifampicin were 29.0%, 27.1%, 21.5%, 10.3% and 11.6%, respectively. The secondary resistance rates in all drugs and combinations were higher than primary resistance rates (p<0.001). Step wise logistic regression revealed that (i) non-compliance with treatment increases the chances of development of resistance by 15 times [p<0.00001, 95% confidence intervals (95% CI) : 4.16 to 56.70], and (ii) a regimen of inadequate treatment increases the chance of development of drug resistance by 10.5 times (p<0.01, 95% CI=2.66 to 49.80). CONCLUSIONS: We propose that specially trained physicians should institute antituberculosis therapy and medication should be practiced under direct observation in this region.
