Clinical significance of smell and taste dysfunction and other related factors in COVID-19.

PURPOSE: The objective of this study is to evaluate smell and taste dysfunction (STD) in coronavirus disease 2019 (COVID-19) positive and negative patients, and to assess the factors associated with STD in COVID-19 positive patients. METHODS: Patients who had been tested with the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for COVID-19 were identified, and according to the RT-PCR test results, patients were separated into Positive and Negative Groups. A telephone-based assessment was applied to both groups using the American Academy of Otolaryngology-Head and Neck Surgery Anosmia Reporting Tool. Patients in Positive Group were also asked to rate STD, nasal breathing, and anxiety in three different time periods (pre-/during-/post-COVID) using the visual analog scale (VAS). RESULTS: A total of 53 COVID-19 positive and 51 negative patients completed the surveys. STD was eightfold more frequent (OR 8.19; CI 95% 3.22-20.84) in the Positive Group. Of the 53 COVID-19 positive patients, 32 reported STD and 21 did not. 'Ground-glass appearance' on chest-computed tomography was more frequent and median lymphocyte count was significantly lower in COVID-19 positive patients with STD. During-COVID STD and nasal breathing VAS scores were significantly lower than the pre- and post-COVID scores. During-COVID STD scores were significantly correlated with anxiety scores (Spearman's rho-0.404, p = 0.022) but not correlated with nasal breathing scores. CONCLUSION: STD may be related to increased inflammatory response as well as damage of olfactory neuronal pathway or non-neuronal olfactory mucosa. Understanding the exact cause of chemosensory impairment in COVID-19 can be helpful in explaining the pathophysiology of the disease.

Evaluation of TyG index and TG/HDL-C ratio in HBeAg negative chronic hepatitis B infected patients.

Patients with hepatitis B e antigen (HBeAg) negative chronic HBV infection are regularly followed up. This study investigates the presence of insulin resistance and the relationship between hepatosteatosis and insulin resistance in patients with HBeAg negative chronic HBV infection using the TyG index and TG/HDL-C ratio. Patients with HBeAg negative chronic HBV infection who applied to the Infectious Diseases and Clinical Microbiology outpatient clinic between January 2019 and December 2020 were included in the study. Glucose, lipid panel, alanine amino transferase (ALT), acetyl amino transferase (AST), body mass index (BMI), TyG index, TG/HDL-C and hepatobiliary ultrasonography (USG) results were evaluated. The data were compared with the control group consisting of 308 HBsAg negative individuals. The study included 132 patients with a median age of 52 years. There was no significant difference between the patient and control groups regarding age, gender and BMI. Glucose, total cholesterol, TG, LDL, AST, ALT, TyG index and TG/HDL-C ratio were significantly higher in patient than in the control group. At the same time, the HDL value was significantly lower in the patients. There was a strong positive correlation between the TG and BMI, and a strong negative correlation between HDL levels and both TyG index and TG/HDL-C ratio. Our findings showed that the TyG index and TG/HDL-C ratio are helpful in the diagnosis of insulin resistance and hepatosteatosis in patients with HBeAg negative chronic HBV infection.

HIV and SARS-Cov-2 Co-Infection: A Local Perspective.

Objective: As the Coronavirus disease 2019 (COVID-19) pandemic spread globally, more human immunodeficiency virus (HIV) positive patients began to appear infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We aimed to evaluate the clinical course of HIV and SARS-CoV-2 co-infected patients from a local perspective. Methods: HIV and SARS-CoV-2 co-infected patients diagnosed between March 2020 to June 2021 at a tertiary hospital in Turkey were analyzed retrospectively. Results: Thirty HIV and SARS-CoV-2 co-infected patients were included. Five patients were female, 25 were male, and the mean age was 44.5 ±10.2 years. Twenty-three (76.7%) patients were known to be HIV-positive before their admission to the hospital, and seven (23.7%) patients, were detected by screening after the diagnosis of COVID-19. All patients were known to be HIV-positive; they were on antiretroviral therapy (ART) and virologically suppressed. Twenty-seven patients had a mild course. Three patients were hospitalized, and of them, two patients had died. All hospitalized patients were male and were ART-naïve. Conclusion: HIV infection alone did not increase the severity of the course of COVID-19 and did not increase the mortality in COVID-19.

Evaluation of neutrophil to lymphocyte ratio in predicting the prognosis of Crimean-Congo haemorrhagic fever.

Crimean-Congo haemorrhagic fever (CCHF) is a severe form of haemorrhagic fever identified in parts of Africa, Asia, Eastern Europe and the Middle East. CCHF continues to be a justifiable cause of concern for people in rural areas where the disease is endemic. A total of 151 patients, diagnosed with CCHF, were evaluated retrospectively. The demographic characteristics of these patients and the relationship between the neutrophil-lymphocyte ratio (NLR) at admission and survival were examined. There were 21 (13.9%) deaths. There was no relationship between age, gender and mortality, but elevated neutrophil-lymphocyte ratio (NLR) on admission was statistically associated with mortality. NLR is a laboratory marker that can be studied even in medical centres with limited facilities and may be helpful in predicting the clinical course of the disease.

Evaluation of pain in patients with COVID-19.

OBJECTIVES: A new type of coronavirus outbreak has emerged in China and caused a pandemic. World Health Organization (WHO) announced the official name of this disease 'COVID-19'. The main purpose of this study is to evaluate pain in COVID-19 patients. METHODS: Patients who were followed in the ward of an infectious diseases department because of possible or confirmed COVID-19 between May and September of 2020 were included in the study. The Turkish version of the Brief Pain Inventory (BPI) was applied. Demographic features, frequency, location, the intensity of pain, and response to analgesics were analyzed. RESULTS: A total of 178 participants were included in the study. Ninety-one (51.1%) of patients had pain complaints and the mean pain score (MPS) was 2.28±2.81 over 10. Fifty-nine (56.0%) of participants with pain required analgesic therapy and 41 (80.3%) of them showed ≥50% pain relief with simple analgesics. Twelve of the remaining 18 who did not get enough pain relief with simple analgesic were taking their analgesics pro re nata (PRN) rather than around the clock (ATC). Pain frequency and intensity and mean hospitalization duration (MHD) were similar between confirmed and possible cases. CONCLUSION: Regarding the results, we conclude that pain is not one of the challenging symptoms and easily manageable in patients with a mild-moderate intensity of COVID-19. Our results were not enough to make a correlation between pain and the clinical course of the disease. Further studies are required for the evaluation of pain including patients in intensive care units.

Enterococcus hirae as a cause of bacteremic urinary tract infection: first case report from Turkey.

INTRODUCTION: Enterococcus hirae (E. hirae) constitutes less than 1% of the enterococci strains in human clinical specimens. In this article, we report the first case of urinary tract infection-related bacteremia due to E. hirae from Turkey. CASE PRESENTATION: A 74-year-old male patient with a history of coronary artery disease, hypertension, and chronic renal failure was admitted to the emergency department with abdominal pain, dysuria, and fever. The urine sample collected from the urinary catheter resulted as ampicillin-sensitive E. hirae. On the 4th day of hospitalization, E. hirae growth with the same sensitivity pattern was also reported in blood culture. Intravenous ampicillin 4×2 g/day treatment was initiated. There was no growth in subsequent blood and urine cultures. Fever resolved and general condition improved. The patient was discharged on the thirteenth day with clinical improvement after moxifloxacin treatment for four days and ampicillin treatment for nine days. DISCUSSION: The patient's medical history included risk factors for enterococcal bacteremia. There are a limited number of reports in the literature describing human infections caused by E. hirae. The reason for the rare isolation of E. hirae from clinical specimens may be the difficulty of identifying with standard diagnostic approaches. CONCLUSIONS: For diagnostic purposes, as in our case, rapid and high sensitive diagnostic methods such as Matrix-assisted Laser Desorption/Ionization Time of Flight (MALDI-TOF) and molecular techniques may be useful to guide the selection of the least toxic and optimal duration of antibiotic treatment.

Rotational thromboelastometry alongside conventional coagulation testing in patients with Crimean-Congo haemorrhagic fever: an observational cohort study.

BACKGROUND: Data describing the coagulopathy of Crimean-Congo haemorrhagic fever are scarce. We did rotational thromboelastometry (ROTEM) and conventional coagulation testing in patients with Crimean-Congo haemorrhagic fever to increase our understanding of the coagulopathy of this infectious disease. METHODS: We did a prospective observational cohort study of adults aged 18 years and older and admitted to hospitals with PCR-confirmed Crimean-Congo haemorrhagic fever in Samsun and Tokat, Turkey. Demographic, clinical, and laboratory data were collected and blood samples for ROTEM analysis and coagulation testing were drawn at admission and during hospital admission and convalescence (up to 30 days after onset of illness). For the ROTEM analysis we recorded the following extrinsically activated ROTEM (EXTEM S) variables, with normal ranges indicated: clotting time (38-79 s), clot formation time (34-159 s), amplitude at 10 min after clotting time (43-65 mm), maximum clot firmness (50-72 mm), and maximum lysis (>15% at 1 h). The following fibrin-specific ROTEM (FIBTEM S) variables were also recorded: amplitude at 10 min after clotting time (normal range 7-23 mm) and maximum clot firmness (9-25 mm). Disease severity was assessed by Swanepoel criteria, severity grading score (SGS), and the severity scoring index (SSI), with mild disease defined as meeting no Swanepoel criteria, graded mild by SSI, and graded low risk by SGS. FINDINGS: Between May 27, 2015, and Aug 2, 2015, 65 patients with confirmed Crimean-Congo haemorrhagic fever were recruited and had blood taken at 110 time points. Most were male (40 [62%] of 65) with mild disease (49 [75%] of 65). Haemorrhage occurred in 13 (20%; 95% CI 11·1-31·8) of 65 patients and 23 (35%) of 65 received blood products (15 received fresh frozen plasma and eight received red blood cell concentrates), and 21 patients received platelet transfusions. At admission, the following EXTEM S variables differed significantly between mild cases and moderate to severe cases: median clotting time 56 s (range 42-81; IQR 48-64) versus 69 s (range 48-164; IQR 54-75; p=0·01); mean amplitude at 10 min after clotting time 45·1 mm (SD 7·0) versus 33·9 mm (SD 8·6; p<0·0001); median clot formation time 147 s (range 72-255; IQR 101-171) versus 197 s (range 98-418; IQR 156-296; p=0·006); and maximum clot firmness 54·4 mm (SD 7·2) versus 45·1 mm (SD 12·5; p=0·003). The EXTEM S variables were compared at different time points; maximum clot firmness (p=0·024) and amplitude at 10 min after clotting time (p=0·090) were lowest on days 4-6 of illness. We found no significant differences in FIBTEM variables between mild and moderate to severe cases (median amplitude at 10 min, 13 mm [range 8-20; IQR 11-15] vs 12 mm [range 6-25; IQR 10-15; p=0·68]; and median maximum clot firmness, 15 mm [range 9-60; IQR 13-21] vs 17 mm [range 7-39; IQR 13-23; p=0·21]); and no hyperfibrinolysis (maximum lysis >15%). INTERPRETATION: Coagulopathy of Crimean-Congo haemorrhagic fever is related to defects in clot development and stabilisation that are more marked in severe disease than in mild disease. The combination of normal and slightly deranged coagulation screens and FIBTEM results with the absence of hyperfibrinolysis suggests that the coagulopathy of Crimean-Congo haemorrhagic fever relates to platelet dysfunction.

Infection prevention and control practice for Crimean-Congo hemorrhagic fever-A multi-center cross-sectional survey in Eurasia.

BACKGROUND: Crimean Congo Hemorrhagic Fever (CCHF) is a life threatening acute viral infection that presents significant risk of nosocomial transmission to healthcare workers. AIM: Evaluation of CCHF infection prevention and control (IP&C) practices in healthcare facilities that routinely manage CCHF cases in Eurasia. METHODS: A cross-sectional CCHF IP&C survey was designed and distributed to CCHF centers in 10 endemic Eurasian countries in 2016. RESULTS: Twenty-three responses were received from centers in Turkey, Pakistan, Russia, Georgia, Kosovo, Bulgaria, Oman, Iran, India and Kazakhstan. All units had dedicated isolation rooms for CCHF, with cohorting of confirmed cases in 15/23 centers and cohorting of suspect and confirmed cases in 9/23 centers. There was adequate personal protective equipment (PPE) in 22/23 facilities, with 21/23 facilities reporting routine use of PPE for CCHF patients. Adequate staffing levels to provide care reported in 14/23 locations. All centers reported having a high risk CCHFV nosocomial exposure in last five years, with 5 centers reporting more than 5 exposures. Education was provided annually in most centers (13/23), with additional training requested in PPE use (11/23), PPE donning/doffing (12/23), environmental disinfection (12/23) and waste management (14/23). CONCLUSIONS: Staff and patient safety must be improved and healthcare associated CCHF exposure and transmission eliminated. Improvements are recommended in isolation capacity in healthcare facilities, use of PPE and maintenance of adequate staffing levels. We recommend further audit of IP&C practice at individual units in endemic areas, as part of national quality assurance programs.
