RESUMO
OBJECTIVES: The natural history of chronic HBV infection (CHB) is generally divided into four phases: HBeAg-positive chronic HBV infection (EPCI) and -hepatitis (EPCH), HBeAg-negative chronic HBV infection (ENCI) and -hepatitis (ENCH). This study aimed to investigate changes in serum quantitative surface antigen (qHBsAg), systemic immune-inflammation index (SII) and systemic inflammatory response index (SIRI) in a large number of CHB patients. METHOD: Three hundred seventy-two CHB patients who underwent liver biopsy between January 2015 and February 2020 were evaluated. RESULTS: The SII-values were strongly significant between EPCI-EPCH ( P = 0.002), however, there was significant difference between ENCI-ENCH ( P = 0.025). Considering the SIRI results, there was a significant difference between both EPCI-EPCH ( P = 0.009) and ENCI-ENCH ( P = 0.118). In HBeAg-positive patients HBV-DNA, qHBsAg, and SII were found to be predictive ( P = 0.029, P = 0.039, P = 0.027, respectively) while in HBeAg-negative patients, age, AST, HBV-DNA, qHBsAg, SII, and SIRI were found to be predictive ( P = 0.047, P = 0.084, P = <0.001, P = 0.001, P = 0.012, P = 0.002, respectively). In EPCH phase, whereby accuracy rate results of HBV-DNA, qHBsAg, and SII were 75.3%, 73.4%, and 60.4%, respectively, while in the ENCH phase the accuracy rates of age, AST, HBV-DNA, qHBsAg, SII, and SIRI values were 57.8%, 65.6%, 68.3%, 63.8%, 57.3% and 53.2%, respectively. CONCLUSION: HBV-DNA, qHBsAg, and SII are predictive in EPCH patients. Age, AST, HBV-DNA, qHBsAg, SII and SIRI are all predictive in ENCH patients. In patients with CHB, we recommend using SII to distinguish between EPCI-EPCH and ENCI-ENCH. Based on its sensitivity and features, we believe that qHBsAg and SII are suitable measuring instruments in discrimination both of EPCI-EPCH and ENCI-ENCH.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a popular weight loss procedure with potential effects on gastroesophageal reflux disease (GERD). However, research on the association between LSG and GERD using objective evaluation criteria, such as multichannel intraluminal impedance combined with pH testing (MII-pH), is limited. This study aimed to investigate the impact of LSG on GERD using MII-pH and current consensus guidelines. MATERIALS AND METHODS: It was conducted as a prospective clinical study on 33 patients who underwent LSG between January 2022 and August 2022. MII-pH and high-resolution manometry were performed preoperatively and 3 to 6 months postoperatively. GERD diagnosis was based on MII-pH results using the Lyon and Update Porto consensus guidelines. RESULTS: Postoperative MII-pH analysis revealed a significant increase in acid reflux time, acid exposure time, reflux index, esophageal clearance, total reflux time, and longest reflux period. Weak acid reflux episodes decreased, while Demeester score and alkaline reflux showed nonsignificant increases. Pathologic reflux significantly increased postoperatively based on MII-pH diagnosis. High-resolution manometry showed a significant increase in unsuccessful motility. CONCLUSION: Although the Demeester score calculation consists of 6 metrics, including acid exposure time, the acid exposure time is more specific in detecting pathologic reflux. Pathologic GERD increases significantly with LSG in the early period. Therefore, preoperative and postoperative endoscopy and MII-pH can provide valuable information regarding the need for closer follow-up after LSG.

INTRODUCTION: Restless legs syndrome (RLS) is a common but underdiagnosed neurological syndrome. It is characterized by the feeling of discomfort and desire to move, especially in the lower extremities, which often occurs at night, and the cure or relief of symptoms with movement. Irisin is a hormonelike polypeptide that was first identified in 2012, weighs 22 kDa, consists of 163 amino acids, and is mainly synthesized in muscle. Its synthesis increases with exercise. Here in this study, we planned to investigate the relationship among serum irisin level, physical activity, lipid profile, and RLS. MATERIAL AND METHODS: A total of 35 patients with idiopathic RLS and 35 volunteers were included in the study. Then, venous blood was taken from the participants in the morning after 12 h of night fasting. RESULTS: The mean value of serum irisin level was 16.9 ± 14.1 ng/mL in the case group and 5.1 ± 5.9 ng/mL in the control group, which was statistically quite significant (p < .001). A significant efficiency (under the curve area 0.886 [0.804-0.967]) of irisin value was observed in the differentiation of patients in the case and control groups. DISCUSSION: Serum irisin level was significantly higher in the case group than in the control group. In conclusion, we suggest that irisin may play a role in the pathophysiology of RLS independently of the intensity and duration of physical activity and anthropometric data, such as body weight, body mass index, and waist/hip ratio.

OBJECTIVE: Hepatotoxicity is one of the major side effects of methotrexate and limits its use. In this study, we investigated the hepatoprotective effect of silibinin and the role of oxidative stress markers and cytokines on high-dose methotrexate-induced hepatotoxicity in rats. MATERIALS AND METHODS: In this study, rats were randomly divided into 5 groups (n=7). Methotrexate (20 mg/kg, intraperitoneally) was administered on the first day in all groups except control. Silibinin was injected for 5 days to methotrexate-silibinin25, methotrexate-silibinin50, and methotrexate-silibinin100 groups at a dose of 25, 50, and 100 mg/kg/day, respectively. On the sixth day, blood and liver samples were obtained and rats were sacrificed. Serum total antioxidant capacity, total oxidant status, total thiol, native thiol, alanine aminotransferase, aspartate transaminase, bilirubin, albumin, tumor necrosis factor-alpha, and interleukin-10 levels were measured. In addition, a histopathological evaluation of liver tissues was performed. RESULTS: Methotrexate reduced total antioxidant capacity and increased disulfide/total thiol ratio. Histopathologic examination revealed that methotrexate increased hepatic damage and 50 mg/kg/dose of silibinin prevented inflammatory cell infiltration in particular. CONCLUSION: Our results suggest that silibinin (50 mg/kg/day) may reduce the hepatic damage in methotrexate-induced hepatotoxicity in rats by increasing antioxidant capacity.
RESUMO
SUMMARY OBJECTIVE: The vast majority of patients who hospitalized with coronavirus disease 2019 are given empirical antibiotic therapy. However, information on the frequency, microorganism species, and resistance rates of secondary bacterial infections in coronavirus disease 2019 patients are insufficient. We aimed to show the frequency of secondary infections and resistance conditions in patients with coronavirus disease 2019 hospitalized in the intensive care unit. METHODS: The results of tracheal aspirate culture, blood culture, and urine culture obtained from coronavirus disease 2019 patients - at least 2 days after their admission to the intensive care unit - were examined microbiologically. RESULTS: A total of 514 patients hospitalized in intensive care unit were included in our study. Tracheal aspirate, blood, or urine cultures were collected from 369 patients (71.8%). Bacterial reproduction was detected in at least one sample in 171 (33.3%) of all patients. The rate of respiratory tract infection and/or bloodstream infection was found to be 21%. Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa in tracheal aspirate culture; Coagulase-negative staphylococci, K. pneumoniae, and A. baumannii in blood culture; and Escherichia coli, K. pneumoniae, and Enterococcus faecalis in urine culture were the most common microorganisms. A. baumannii was resistant to most antibiotics except colistin and P. aeruginosa strains were resistant to most antibiotics except amikacin, colistin, cefepime, and imipenem. In K. pneumoniae, the highest meropenem sensitivity (73%) was observed; there was a strong resistance to most of the remaining antibiotics. CONCLUSIONS: We think that our study can be useful in choosing empirical antibiotic therapy in the coronavirus disease 2019 pandemic and reducing the mortality that may occur with secondary infection.

PURPOSE: The aim of this study was to investigate the importance of atherosclerosis in the pathogenesis of sudden hearing loss by evaluating the newly discovered markers, serum salusin-α and salusin-ß. We also aimed to evaluate atherosclerosis risk factors, such as lipid profile, smoking, body mass index, waist circumference and mean blood pressure of the patients. METHODS: Fifty-two patients diagnosed with sudden hearing loss (study group) and fifty healthy people (control group) were included in the study. Detailed history was taken from the patients and risk factors for atherosclerosis, such as smoking, body mass index, waist circumference, lipid profile, mean blood pressure and serum salusin-α and salusin-ß levels, were evaluated. The study group was divided into recovery group (subgroup I) and non-recovery group (subgroup II). RESULTS: The salusin-ß median value was found to be significantly higher in the study group compared to the control group (p < 0.05). The salusin-ß median value was found to be significantly higher in subgroup 2 and was found to be a poor prognostic factor (p < 0.05). CONCLUSION: From the results obtained in this study, it is thought that salusin-ß peptide is increased in patients with sudden hearing loss and it can be evaluated as a poor prognostic factor.

To investigate the presence of respiratory viruses in the middle ear cavity of the individuals with a healthy middle ear and the children with otitis media with effusion (OME). A total of 72 middle ear samples were collected from 25 children with OME (Group 1) and 47 individuals with no middle ear disease (Group 2). Multiplex real-time polymerase chain reaction was used to investigate the presence of 20 different respiratory viruses. Virus results were compared with bacteriomes of the same populations. At least one respiratory virus was detected in 56% of the patients in Group 1 and 12.8% of the individuals in Group 2. The viral co-infection rate for Group 1 and 2 was 8% and 2.1%, respectively. In Group 1, adenovirus was the most frequently detected virus with a rate of 24%, either alone (16%) or concurrent with other viruses (8%), followed by influenza B (12%), rhinovirus, and bocavirus (8%) each. Parainfluenza 4, coronavirus OC43, and RSV A/B were detected in 4% of the sample each. In Group 2, rhinovirus was detected in two samples (4.3%) followed by adenovirus, coronavirus OC43, coronavirus E299, and coronavirus NL63 with a rate of 2.1% each. The detection rate of respiratory viruses was significantly higher in children aged 6 to 11 years. There was no positive association between virus and bacteria found in the middle ear cavity. The current study has provided comprehensive data indicating the presence of diverse respiratory viruses in the healthy middle ear cavity. Our results also suggest that respiratory viruses might have a contribution to OME pathogenesis.

OBJECTIVES: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is mainly transmitted through respiration and direct contact. The status of the infection in the female genital system is still unknown. The study aimed to evaluate whether SARS-CoV-2 is present in the vaginal fluid of women with COVID-19 infection in reproductive period. MATERIAL AND METHODS: Women who were between the ages of 18-50 years and clinically confirmed to have COVID-19 infection at our hospital between 20 April-31 May 2020 were included in the study. Women who were in their menstrual cycle during the study and who had a known cervical intraepithelial lesion and/or cancer, sexually transmitted disease and history and/or symptoms of vaginitis were excluded from the study. In patients in whom no pathology was detected during the examination, a sample was taken from the vaginal fluid for PCR by using Dacron tip swab. Analysis was performed with Genesig Real-Time PCR COVID-19 kit (Primer Design, England). RESULTS: Eighteen women who were in reproductive period and diagnosed with severe COVID-19 pneumonia were included in the study. The mean age of the patients was 38.16 ± 8.54. None of the patients were in their menopause period. The clinical symptoms of these women were similar to those of confirmed severe COVID-19 cases. SARS-CoV-2 was found to be negative in the samples taken from the vaginal fluid in all patients. CONCLUSIONS: SARS-CoV-2 virus was not detected in the vaginal fluid of the patients who tested positive for COVID-19 in reproductive period.
RESUMO
Background/aim: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Turkey on March 10, 2020 and the number of the patients are increasing day by day. Coronavirus disease 2019 (Covid-19) has high mortality rates in intensive care units (ICUs). We aimed to describe the demographic characteristics, comorbidities, treatment protocols, and clinical outcomes among the critically ill patients admitted to the ICU of our hospital. Materials and methods: This cohort study included 103 consecutive patients who had laboratory confirmed Covid-19 and admitted to ICU of Sakarya University Training and Research Hospital between March 19 and April 13, 2020. The final date of the follow-up was April 18. Results: The mean age of the patients was 69.6 ± 14.1 years. Most of the patients had increased CRP (99%), serum ferritin (73.8%), d-dimer (82.5%), and hs-troponin levels (38.8%). 34 patients (33%) had lymphocytopenia, 24 patients (23.3%) had thrombocytopenia. 63 patients (61.2%) developed acute respiratory distress syndrome (ARDS), 31 patients (30.1%) had acute kidney injury, and 52 patients (50.5%) had multiple organ dysfunction syndrome (MODS) during follow-up. Sixty-two patients (60.2%) received mechanical ventilation. As of April 18, of the 103 patients, 52 (50.5%) had died, 30 (29.1%) had been discharged from the ICU, 21 (20.4%) were still in the ICU. Conclusions: Covid-19 has high mortality rates in ICU. Patients with elevated procalcitonin, hs-troponin, d-dimer, and CRP levels and lower platelet count at admission have higher mortality.

Background/aim: The COVID-19 infection, which started in Wuhan City, China, in December 2019, turned into a pandemic in a very short time, affecting mainly the elderly and those with serious chronic illnesses. COVID-19 infections have been observed to have a high mortality rate, especially in patients undergoing maintenance hemodialysis. Materials and methods: Forty-two patients over 18 years of age who underwent a maintenance hemodialysis program at our unit, who tested positive for COVID-19 by PCR from nasopharyngeal swabs, and/or who were observed to have disease-related signs in their CTs were included in the study. Results: In this study, 23 of 42 patients receiving hemodialysis support in our clinic were included. The median age was 67 years old (min: 35; max: 91 years), and all of our patients had primary hypertension and other comorbidities. Their clinical evaluation showed that dry cough (47.8%) and shortness of breath (47.8%) were the most common symptoms. Fever was less pronounced (30.4%). The median time from the onset of symptoms to hospitalization was 1 day (min: 0; max:), and the time from hospitalization to death was 18 days (min: 1; max: 22). Transfer from the inpatient ward to the ICU took a median of 7 days (min: 1; max: 13). Among the 23 patients, 3 died during follow-up, and 20 were discharged with full recovery. Baseline ferritin, procalcitonin levels, and CRP/albumin rates were higher, and neutrophil/lymphocyte levels were lower in patients who eventually died. In these patients, despite being nonsignificant, there were more diabetic patients, and the D-dimer levels were higher than 1000 ugFEU/L. Conclusion: The COVID-19 infection is associated with increased mortality in chronic kidney diseases patients. Despite being nonsignificant, there was a trend towards increased mortality in patient with diabetes, D-dimer levels >1000 ugFEU/L, higher ferritin and prokalsitonin levels, an increased CRP/albumin ratio, and a lower neutrophil/lymphocyte ratio.

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.

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.

Medical laboratory personnel may be exposed to various hazards, especially biological and chemical, during their routine activities. In this multicenter study, which could reflect the nation wide results, it was aimed to determine the safety and biosecurity practices of the employee working in medical microbiology laboratories and to reveal the current situation. A total of 1072 personnel working in the Medical Microbiology Laboratory of 23 hospitals (14 medical faculty hospitals, seven ministry of health training and research hospitals and two state hospitals) from different provinces were provided with a questionnaire consisting of 33 questions inquiring about the rules, opinions, attitudes and behaviors regarding safety and biosafety practices. Statistical analyses were made with institutions, age groups, gender, educational background, working time and occupational groups in terms of exposure to biological and chemical hazards. It was determined that approximately 50% personnel of the university/ training and research hospitals and 2/3 of the state hospitals personnel consumed food and beverages in the laboratories (p<0.05). Compared with other hospitals, it was determined that in state hospitals; the absence of separate resting room (35%), the personnel finding their own knowledge and practices inadequate (28.9%), laboratory coats washed at home (95%), educational organization and participation rates (90%) and medical waste information levels of the personnel were higher (p< 0.05). It was determined that as the age progresses, the rate of education, food and beverage consumption in the laboratory, not being outside the laboratory with protective equipment (gloves, masks and laboratory coats) and the history of laboratory acquired infections were increased (p< 0.05). It was observed that washing the laboratory coats at home was higher in the younger age group and hospital washing was higher in the elderly group (p< 0.05). There was no significant difference between the genders in terms of food and beverage consumption in the laboratory (p= 0.09). It was determined that periodic health checks were not performed in 1/3 of both sexes, but the use of gloves and compliance with medical waste rules was lower in men. Female employees find themselves inefficient in terms of knowledge and practices (p< 0.05). The rate of those who did not have their periodic checkups at regular intervals was higher in the high school and master of science education groups; While non-compliance with medical waste rules, food and beverage consumption in the laboratory was highest in the primary and high school graduates, the lowest rates were found in the master and doctorate groups (p< 0.05). The rate of those who had regular health checkups was higher in the group of specialist physicians and technicians (p< 0.05). It was observed that the rule of not going out of the laboratory with protective equipment was fully observed in the 35+ years working group, while compliance was 70-85% in other groups (p< 0.05), hepatitis B vaccination rate was highest in specialist doctors and lowest in cleaning and other personnel group (p< 0.05). Highest non-compliance rate with medical waste rules was observed in the cleaning personnel group (p< 0.05). As a result, although advances have been made in employee safety practices in medical microbiology laboratories in our country in recent years, it has been found that it is not yet sufficient. The results indirectly reflected the profile of medical laboratories in our country. In the laboratories, physical space and equipment deficiencies should be eliminated, periodic health checkups and vaccination should be provided, non-staff entrance to the laboratory and food, beverage and cigarette consumption should be prevented, laboratory coats should be washed in the hospital, in-service trainings, including medical waste training, should be conducted and these trainings should be developed through mechanisms that will change the behavior.

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.

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.

BACKGROUND: Hepatitis E virus (HEV) infection is usually an acute self-limiting disease, which causes rapidly progressive cirrhosis and chronic infection in patients with hematological malignancies, patients requiring chemotherapy, and HIV-infected patients. The aim of this study was to investigate the positivity of hepatitis E IgM and IgG in HIV positive patients with the recently introduced Enzyme Linked Fluorescent Assay (ELFA) commercial kits. MATERIALS AND METHODS: The study included 126 patients who were followed up by the Infectious Diseases and Clinical Microbiology Clinic of Sakarya University Training and Research Hospital between October 2017 and December 2018 for HIV positivity. Serum samples of the patients were evaluated for anti-HEV IgG and IgM positivity with a novel commercially available kit using the ELFA method (bioMerieux, France). The study group consisted of 126 patients with HIV infection. Anti-HEV IgG antibodies were studied primarily from plasma samples. Anti-HEV IgM positivity was also investigated in patients with anti-HEV IgG positivity. RESULTS: The study group consisted of 114 (90.5%) males and 12 (9.5%) females with a mean age of 38.11 ± 13.32 (min: 18, max: 80) years. Anti-HEV IgG was positive in 5 (4.0%) HIV-positive patients. One of the anti-HEV IgG positive patients was newly diagnosed with HIV and the other four patients were being followed up for HIV positivity. Anti-HEV IgM was negative in all patients. None of the patients with anti-HEV IgG positivity had anti-HCV and HBsAg positivity. CONCLUSIONS: In the study, anti-HEV IgG positivity was found to be 4% in HIV-positive individuals, and no HCV and HBV co-infection was detected in any patients with HIV and HEV coexistence. HEV infections do not emerge as a priority among HIV-infected people, but HEV should also be investigated in HIV-infected individuals with liver abnormalities of uncertain etiology.

OBJECTIVE: Water-pipe smoking has become a serious public health threat worldwide. In order to raise awareness of adverse effects and transmission of bacteria via water-pipe smoking, we aimed to identify the bacteria and their antimicrobial resistance profiles that colonize different parts of waterpipes. METHODS: We examined totally 182 water pipes from 7 lounges (in Turkey) used in public places and we collected 728 culture samples in total by microbiological methods. We used disposable sterile swabs to sample the inside and outside of the mouthpiece, and the handling piece and sterile injectors were used to collect 5 mL of water from the water pipe bowl. RESULTS: There was a significant (p < 0.05) difference in microbial contamination (growth/presence of bacteria and fungi) among the parts of the water pipes sampled. There was a significant (p < 0.05) difference in the number of bacteria growing (microbial load) among the parts of the water pipes. Only one narghile lounge out of seven, which had 13 water pipes, had a hygiene procedure. The water jars are often contaminated with Gram-negative bacteria. CONCLUSION: Water pipes, especially the interior and outer part of the mouthpieces and the handle, are colonized by microbes and pose a risk of infection. Procedures for water pipe hygiene should be developed, periods should be defined, and the owners and employees of establishments and water-pipe smokers should be educated in this regard. Water-pipe smoking is a threat to public health and should be regulated by the state.

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.

SUMMARY OBJECTIVES The 2019 Novel coronavirus disease puts a serious burden on the health system. Therefore, the detection of particularly serious patients at an early stage is extremely important in terms of controlling the outbreak and improving the prognosis. We investigated the role of inflammatory markers studied in patients suspected of COVID-19 at an emergency department in predicting PCR and CT results. METHODS This retrospective study was carried out with 133 patients who were admitted between 13 March and 1st April 2020 with suspicion of COVID-19. The patients were divided into four groups according to CT and RT-PCR results and evaluated. RESULTS Considering all patients, no specific findings were found in the hematological and biochemical values of patients in the laboratory analyses. Although all of the results remained within the reference range, there was a significant difference in white blood cell, neutrophil, platelet, and lymphocyte values when the groups were compared [p = 0.000; p = 0.004; p = 0.022; p = 0.023]. CONCLUSION Laboratory is not specific enough in the pre-diagnosis. In addition, this result does not alter with PCR or CT positivity. However, minimal changes observed in laboratory results may be partially guiding in patients in whom both PCR and CT are positive.
RESUMO OBJETIVOS A nova doença de coronavírus de 2019 coloca um fardo sério para o sistema de saúde. Portanto, a detecção de pacientes especialmente graves em um estágio inicial é extremamente importante em termos de controle do surto e melhoria do prognóstico. Investigamos o papel dos marcadores inflamatórios estudados em pacientes suspeitos de COVID-19 no pronto-socorro na previsão de resultados de PCR e CT. MÉTODOS Este estudo retrospectivo foi realizado entre 133 pacientes que foram admitidos entre 13 de março e 1o de abril de 2020 com suspeita de COVID-19. Os pacientes foram divididos em quatro grupos de acordo com os resultados da TC e RT-PCR e avaliados. RESULTADOS Considerando todos os pacientes, não foram encontrados achados específicos nos valores hematológicos e bioquímicos dos pacientes em análises laboratoriais. Embora todos os resultados tenham permanecido dentro do intervalo de referência, houve uma diferença significativa nos valores de glóbulos brancos, neutrófilos, plaquetas e linfócitos quando os grupos foram comparados [p = 0,000; p = 0,004; p = 0,022; p = 0,023]. CONCLUSÃO O laboratório não é suficientemente específico no pré-diagnóstico. Além disso, este resultado não se altera com a positividade para PCR ou CT. No entanto, alterações mínimas observadas nos resultados laboratoriais podem ser parcialmente norteadoras em pacientes com PCR e CT positivos.
