RESUMO
OBJECTIVES: Genetic predisposition plays a role in the etiology of metabolic syndrome (MetS), an important health problem worldwide. Leptin (LEP), produced by adipose tissue, plays a crucial role in the development of MetS. In this study, we evaluated the effects of LEP and LEP receptor (LEPR) variants on clinical findings and risk of developing MetS in the Turkish population. METHODS: A total of 320 patients were included in the study, of whom 150 were patients with MetS and 170 were healthy controls. DNA was extracted from blood samples. LEP rs7799039 and LEPR rs1137101 variants were genotyped using the polymerase chain reaction-based restriction fragment length polymorphism method. The genotype distributions of these variants and clinical and laboratory findings were compared. RESULTS: The LEP rs7799039 GA and AA genotypes and A allele frequencies were higher in participants with MetS than in the control group. For LEP rs7799039, the genotype AA-GA was higher in males, and the GG genotype was higher in females. On analyzing the clinical outcomes associated with these variants, it was observed that individuals possessing LEP rs7799039 GA and AA genotypes displayed elevated levels of triglycerides. In addition, those with the AG-GG genotype of LEPR rs1137101 had lower mean hemoglobin levels. CONCLUSION: Our results showed that the LEP rs7799039 and LEPR rs1137101 variants may be associated with both the risk of MetS development and clinical findings. Among the various contributors to MetS, a genetic predisposition is commonly recognized as the primary cause.
RESUMO
BACKGROUND AND PURPOSE: Studies have found that up to 73% of COVID-19 patients experience hyposmia. It is unclear if the loss of smell in COVID-19 is due to damage to the peripheral or central mechanisms. This study aimed to explore the impacts of COVID-19-induced hyposmia on brain structure and cognitive functions. METHODS: The study included 36 hyposmic (h-COV) and 21 normosmic (n-COV) participants who had recovered from mild COVID-19 infection, as well as 25 healthy controls (HCs). All participants underwent neurological examination, neuropsychiatric assessment and Sniffin' Sticks tests. High-resolution anatomical images were collected; olfactory bulb (OB) volume and cortical thickness were measured. RESULTS: Addenbrooke's Cognitive Examination-Revised total and language sub-scores were slightly but significantly lower in the h-COV group compared to the HC group (p = 0.04 and p = 0.037). The h-COV group exhibited poorer performance in the Sniffin' Sticks test terms of discrimination score, identification score and the composite score compared to the n-COV and HC groups (p < 0.001, p = 0.001 and p = 0.002 respectively). A decrease in left and right OB volumes was observed in the h-COV group compared to the n-COV and HC groups (p = 0.003 and p = 0.006 respectively). The cortical thickness analysis revealed atrophy in the left lateral orbitofrontal cortex in the h-COV group compared to HCs. A significant low positive correlation of varying degrees was detected between discrimination and identification scores and both OB and left orbital sulci. CONCLUSION: Temporary or permanent hyposmia after COVID-19 infection leads to atrophy in the OB and olfactory-related cortical structures and subtle cognitive problems in the long term.
RESUMO
The aim of this study was to investigate the reinfection rates and characteristics of SARS-CoV-2 in individuals with SARS-CoV-2 RNA present in their clinical specimens for COVID-19. Our data from the COVID-19 Laboratory of Istanbul University were analyzed for 27,240 cases between 27 March 2020 to 8 February 2022. Demographic characteristics, vaccination statuses, comorbidities, and laboratory findings were evaluated in cases with suspected reinfection, as determined by the presence of SARS-CoV-2 RNA at a rate of 0.3% in clinical specimens. When comparing laboratory values, leukocyte counts were lower in the second and third infections compared with the first infection (p = 0.035), and neutrophil counts were lower in the second infection (p = 0.009). Symptoms varied, with coughing being common in the first infection and malaise being common in subsequent infections. These results suggest that it is important to continue to monitor reinfection rates and develop strategies to prevent reinfection. Our results also suggest that clinicians should be aware of the possibility of reinfection and monitor patients for recurrent symptoms.

Introduction: This study examines the association between perceived stress, death anxiety, psychological resilience and the sociodemographic and clinical features of patients with Coronavirus Disease 2019 (COVID-19). Methods: 304 patients with COVID-19 diagnosis, who were admitted to Istanbul University Istanbul Faculty of Medicine Hospital "COVID-19 Patients Monitoring Center" were recruited. No sample selection was made, all the patients who were followed up and treated in the center were included. Data was collected by the researchers through face-to-face interviews using the Sociodemographic Information and Disease Progression Form, Psychological Hardiness Scale (PHS), Perceived Stress Scale (PSS), and Templer Death Anxiety Scale (TDAS). Results: Women scored higher in PSS and TDAS. Participants with chronic diseases reported higher death anxiety whereas perceived stress was higher in individuals with psychiatric disorders and ones without a history of intensive care unit stay. Participants without psychiatric disorders, who had longer hospitalization and who fully recovered scored higher in PHS-Control. Patients' report of negative attitudes from their relatives/friends was associated with lower scores in PHS. Perceived stress was correlated with death anxiety and psychological resilience. Conclusion: Being female, comorbid physical and mental illnesses, continuation of disease symptoms and low psychological resilience were found to be risk factors in terms of stress and death anxiety in COVID-19 patients. These vulnerable groups need to be closely evaluated with a bio-psychosocial approach and provided psychological support during the course of the disease. Health institutions are recommended to conduct medical treatment in cooperation with psychological care.
RESUMO
Oxidative stress (OS), which leads to DNA damage, plays a role in the pathogenesis of Coronavirus disease 2019 (COVID-19). We aimed to evaluate the role of DNA repair gene variants [X-ray repair cross complementing 4 (XRCC4) rs28360071, rs6869366, and X-ray cross-complementary gene 1 (XRCC1) rs25487] in susceptibility to COVID-19 in a Turkish population. We also evaluated its effect on the clinical course of the disease. A total of 300 subjects, including 200 COVID-19 patients and 100 healthy controls, were included in this study. These variants were genotyped using polymerase chain reaction (PCR) and/or PCR-restriction fragment length polymorphism (RFLP) methods. The patients were divided into three groups: those with a mild or severe infection; those who died or lived at the 28-day follow-up; those who required inpatient treatment or intensive care. There were 87 women (43.5%) and 113 men (56.5%) in the patient group. Hypertension was the most common comorbidity (26%). In the patient group, XRCC4 rs6869366 G/G genotype and G allele frequency were increased compared to controls, while XRCC4 rs6869366 G/T and T/T genotype frequencies were found to be higher in controls compared to patients. For XRCC1 rs25487, the A/A and A/G genotypes were significantly associated with COVID-19 disease. All of the patients hospitalized in the intensive care unit had the XRCC4 rs6869366 G/G genotype. In this study, we evaluated for the first time the impact of DNA repair gene variants on COVID-19 susceptibility. Results suggested that XRCC4 rs6869366 and XRCC1 rs25487 were associated with COVID-19 suspectibility and clinical course.

The suppressor of the cytokine signaling-1 (SOCS1) gene is a short sequence located on chromosome 16 that functions to induce an appropriate immune response and is an essential physiological regulator of interferon (IFN) signaling. In addition to comparing the global DNA and SOCS1 gene promoter methylation status between our patients with coronavirus disease 2019 (COVID-19) and healthy controls, this study demonstrates the effect of the SOCS1 rs33989964 polymorphism on patients with COVID-19. The study group included 139 patients diagnosed with COVID-19 in our hospital's clinics between June and December 2020, and the control group included 78 healthy individuals. After comparing the initial gene polymorphisms of the patients with the healthy control group, three separate clinical subgroups were formed. The gene polymorphism distribution and the methylation status of SOCS1 were examined in these clinical subgroups. Hypomethylation of the SOCS1 gene was observed in the COVID-19 patient group compared to the healthy control group (p = 0.001). Between the patients divided into two separate clinical subgroups, those with severe and mild infections, the Del/Del genotype of the SOCS1 gene was more common in patients with severe infection than in patients with mild infection (p = 0.018). Patients with the CA/CA and CA/Del genotypes were 0.201 times more likely to have a severe infection (95% CI: 0.057-0.716, p = 0.007). Having a non-Del/Del genotype was a protective factor against severe infection. The effect of the SOCS1 rs33989964 polymorphism and methylation status of the SOCS1 gene throughout the COVID-19 pandemic could be significant contributions to the literature.

BACKGROUND: Galectin-3 has been shown to play a key pathophysiological role in pulmonary associated inflammatory response and lung fibrosis in COVID-19 and is a mediator for viral adhesion. However, there is limited data about its potential role in severity and prognosis of COVID-19. This study aimed to investigate the predictive role of serum galectin-3 concentrations in the severe clinical outcomes of hospitalized COVID-19 patients: the severity of pneumonia, in-hospital mortality, and the need for intensive care unit (ICU) admission. METHODS: This single-center study included 68 patients with laboratory- and radiologically-confirmed COVID-19 admitted to our emergency department. The study population was divided into patients with primary clinical out-comes (n = 32) and those without (n = 36). The need for ICU admission and/or in-hospital mortality were the primary clinical endpoints. The study group was also classified based on pneumonia severity: severe or mild/moderate. Blood samples were collected within 48 hours of admission to estimate serum galectin-3 concentrations. RESULTS: Multivariate regression analysis showed that lower concentrations of galectin-3 and arterial oxygen saturation (SpO2) were independently associated with the primary clinical outcomes (OR = 0.951, p = 0.035; OR = 0.862, p = 0.017, respectively); increased concentrations of galectin-3 were an independent predictor of severe pneumonia (OR = 1.087, p = 0.016). In the receiver operating characteristics curve analysis, serum galectin-3 concentrations at hospital admission predicted pneumonia severity with 52.1% sensitivity and 90% specificity with a cutoff of 38.76 ng/mL. CONCLUSIONS: Circulating galectin-3 at hospital admission could be a useful biomarker for identifying COVID-19 patients at high risk for severe pneumonia.

PURPOSE: While the definitive diagnosis of COVID-19 relies on PCR confirmation of the virus, the sensitivity of this technique is limited. The clinicians had to go on with the clinical diagnosis of COVID-19 in selected cases. We aimed to compare PCR-positive and PCR-negative patients diagnosed as COVID-19 with a specific focus on older adults. METHODS: We studied 601 hospitalized adults. The demographics, co-morbidities, triage clinical, laboratory characteristics, and outcomes were noted. Differences between the PCR (+) and (-) cases were analyzed. An additional specific analysis focusing on older adults (≥65 years) (n = 184) was performed. RESULTS: The PCR confirmation was present in 359 (59.7 %). There was not any difference in terms of age, sex, travel/contact history, hospitalization duration, ICU need, the time between first symptom/hospitalization to ICU need, ICU days, or survival between PCR-positive and negative cases in the total study group and older adults subgroup. The only symptoms that were different in prevalence between PCR-confirmed and unconfirmed cases were fever (73.3 % vs. 64 %, p = 0.02) and fatigue/myalgia (91.1 % vs. 79.3 %, p = 0.001). Bilateral diffuse pneumonia was also more prevalent in PCR-confirmed cases (20 % vs. 13.3 %, p = 0.03). In older adults, the PCR (-) cases had more prevalent dyspnea (72.2 % vs. 51.4 %, p = 0.004), less prevalent fatigue/myalgia (70.9 % vs. 88.6 %, p = 0.002). CONCLUSION: The PCR (+) and (-) cases displayed very similar disease phenotypes, courses, and outcomes with few differences between each other. The presence of some worse laboratory findings may indicate a worse immune protective response in PCR (-) cases.

BACKGROUND: While there are substantial reports on the acute phase of Covid-19, the data on post-Covid phase are limited. AIM: To report the data on older post-Covid patients comparatively with the young adults. STUDY DESIGN: Retrospective, single-center study in post-Covid outpatient clinic. Clinical characteristics, laboratory examination, chest imagings were examined. RESULTS: 665 patients were included (median age, 46; 53 %, male; 10.5 %, aged ≥65). We assessed patients at 47th day (median) after recovery. 43.6 % were suffering from one or more ongoing symptomatology. The prevalence of symptoms or physical examination findings were not different between older and younger groups. Most prevalent ongoing symptom was dyspnea (14.3 % and 11.8 % older and younger group, respectively). Most common laboratory abnormality was high pro-BNP (12.2 %, in both age groups). Despite there was no differences regarding imaging findings at acute-phase, there were higher rates of control imaging abnormalities in older subgroup (35.7 % vs 19.4 %; p = 0.006). On admission 28.4 % younger patients had normal imaging, of whom 12.4 % developed some form of sequela; however, in older group, 40.0 % had normal imaging, of whom 25.0 % developed sequela. CONCLUSION: Complaints related to Covid-19 persisted in about half of the patients at about 1.5 months after Covid. More than 1/3 older post-Covid patients displayed pulmonary sequela in the post-acute period which was more prevalent than those in younger adults. Hence, compared to the younger counterparts, the clinicians should be alert in follow-up of older adults for subsequent pulmonary sequela, even among those that had normal imaging finding on initial presentation.

BACKGROUND: The purpose of this study is to evaluate the prognostic roles of hemostatic tests including prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, D-dimer, and antithrombin III in the progression of disease, monitorization of severe, mild and moderate cases, and also to show their relationship with inflammatory markers including C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6). METHODS: The study comprised 604 patients (360 men and 244 women) with confirmed SARS-CoV-2 infection admitted to Emergency Department of Istanbul Faculty of Medicine between March 15 and April 15, 2020. The variations in the concentration of coagulation tests and inflammatory markers were observed from the admission to hospital to the 10th day with three-day periods. RESULTS: PT level and PT activity of severe cases were significantly different compared to mild cases (p = 0.012, p = 0.010, respectively). Similarly, aPTT and D-dimer levels in severe cases were significantly higher compared to the mild cases. However, fibrinogen levels of mild cases were significantly lower compared to either moderate or severe cases (p < 0.001, for both). The PT, PT activity, aPTT, and D-Dimer levels in severe cases were significantly different compared with the mild cases. However, fibrinogen level was the highest in severe cases, and higher than either mild or moderate cases. CONCLUSIONS: Our findings reveal the vital importance of measuring coagulation parameters at the time of admission and monitoring them at regular intervals in clinical monitoring of COVID-19 patients, in determining the severity of the disease in terms of the patient's prognosis, and in choosing and applying the appropriate treatment at the right time.

OBJECTIVE: Severe acute respiratory syndrome (SARS) coronavirus 2 (SaRS-Cov-2) associated respiratory disease (COVID-19), announced as a pandemic, is a multisystem syndrome. SARS-CoV-2 directly infects and damages vascular endothelial cells, which leads to microvascular dysfunction and promotes a procoagulant state. Dipyridamole (DP) acts as a reversible phosphodiesterase inhibitor and is used mainly as an antiplatelet agent. It is hypothetised that it has possible activities in COVID-19. DESIGN AND METHODOLOGY: We report our retrospective, real-world results of DP added to low-molecular weight heparin (LMWH) in the treatment of 462 clinically diagnosed and hospitalized COVID-19 patients. We compared anticoagulation with and without DP addition with no administration of anticoagulation in the same time frame. The primary outcome was proven or highly suspected coagulopathy within 30 days of hospitalization. RESULTS: Definitive coagulopathy has been diagnosed in 3 (3.5%) of 85 LMWH administered patients and 7 (2.13%) of 328 DP + LMWH received patients (P=0.456). Five cases with definitive coagulopathy were not initiated any anticoagulation at the time of the event. The multivariate analysis showed that DP addition to the anticoagulant approach did not have any impact on the risk of demonstrated coagulopathy and highly-suspected coagulopathy. CONCLUSION: We think that our clinical experience is valuable in showing the real-life results of DP + LMWH treatment in COVID-19. This approach did not affect the coagulopathy rate. Our data did also not document an additive effect of DP in the COVID-19 outcome. Prospective controlled trials would give more convincing results regarding the role of DP in COVID-19 endothelial dysfunction and clinical outcome.
RESUMO
BACKGROUND: The severe acute respiratory syndrome coronavirus 2 virus was found to have effects not only in the lungs but also in many different organs. We aimed to evaluate the management of our patients with inflammatory bowel disease in this pandemic, the incidence of coronavirus disease 2019 in terms of clinical, medical treatment, and features of inflammatory bowel disease, and to investigate the effects of the severe acute respiratory syndrome coronavirus 2 on this particular group of patients. METHODS: During the coronavirus disease 2019 pandemic, 207 patients who had inflammatory bowel disease for at least 6 months were questioned for coronavirus disease 2019 at their outpatient clinic admissions, and their medical records were evaluated prospectively. RESULTS: Of the 207 patients, 146 had Crohn's disease. The mean disease duration was determined as 118.15 ± 72.85 months. Of the patients, 127 (61.4%) were using mesalazine, 110 (53.1%) azathioprine, and 148 (71.5%) biological agents. It was found that 66 (31.9%) patients changed their medications during the coronavirus disease 2019 pandemic. As a medication change, anti-Tumor Necrosis Factor (TNF) dose was observed to be omitted most frequently at a rate of 80%. Diarrhea was present in 20.8%, abdominal pain in 20.3%, nausea in 10.6%, anorexia in 13.5%, and weight loss in 15.9% of the patients. Twelve (5.79%) patients were diagnosed with coronavirus disease 2019. Lung involvement was present in 11 (91.7%) of the patients diagnosed with coronavirus disease 2019. Of the patients diagnosed and not diagnosed with coronavirus disease 2019, 75% vs. 71.6% were using biological agents (P = .80), respectively. Half of the patients diagnosed with coronavirus disease 2019 were active in terms of inflammatory bowel disease at the time of diagnosis, and 2 of these patients were severely active. CONCLUSION: The incidence of coronavirus disease 2019 infection in patients with inflammatory bowel disease was not different from the general population during the severe acute respiratory syndrome coronavirus 2 pandemic. Coronavirus disease 2019 infection does not progress with poor prognosis in patients with inflammatory bowel disease who receive immunosuppressive therapy including biological agents.

BACKGROUND: Acute kidney injury (AKI) in COVID-19 patients is associated with poor prognosis. However, the incidence, risk factors and potential outcomes of AKI in hospitalized patients are not well studied. MATERIALS AND METHODS: This is a retrospective cohort study conducted in two major university hospitals. Electronic health records of the patients, 18 years or older, hospitalized between 13 April and 1 June 2020 with confirmed COVID-19 were reviewed. We described the incidence and the risk factors for AKI development in COVID-19 patients. Furthermore, we investigated the effects of AKI on the length of hospital and intensive care unit (ICU) stay, the admission rates to ICU, the percentage of patients with cytokine storm and in-hospital mortality rate. RESULTS: Among 770 hospitalized patients included in this study, 92 (11.9%) patients developed AKI. The length of hospitalized days (16 vs 9.9, p < 0.001) and days spent in the hospital until ICU admission (3.5 vs. 2.5, p = 0.003) were higher in the AKI group compared to patients without AKI. In addition, ICU admission rates were also significantly higher in patients with AKI (63% vs. 20.7%, p < 0.001). The percentage of patients with AKI who developed cytokine storm was significantly higher than patients without AKI (25.9% vs. 14%, p = 0.009). Furthermore, the in-hospital mortality rate was significantly higher in patients with AKI (47.2% vs. 4.7%, p < 0.001). CONCLUSIONS: AKI is common in hospitalized COVID-19 patients. Furthermore, we show that AKI increases the admission rates to ICU and in-hospital mortality. Our findings suggest that AKI should be effectively managed to prevent the adverse outcomes in COVID-19 patients.

For COVID-19 (Coronavirus Disease-2019) cases, detecting host-based factors that predispose to infection is a very important research area. In this study, the aim is to investigate the MBL2 and NOS3 gene polymorphisms in COVID-19 patients with lung involvement, whose first nasopharyngeal PCR results were negative. Seventy-nine patients diagnosed with COVID-19 between April-June 2020 who were admitted to a university hospital, and 100 healthy controls were included. In the first statistical analysis performed between PCR-positive, CT-negative and PCR-negative, CT-positive patients; the AB of MBL2 genotype was significantly higher in the first group (p = 0.049). The B allele was also significantly higher in the same subgroup (p = 0.001). The absence of the AB genotype was found to increase the risk of CT positivity by 6.9 times. The AB genotype of MBL2 was higher in healthy controls (p = 0.006). The absence of the AB genotype was found to increase the risk of CT positivity; also, it can be used for early detection and isolation of patients with typical lung involvement who had enough viral loads, but whose initial PCR results were negative.

Subclinical atherosclerosis and cardiovascular events are common even in young normotensive patients with autosomal dominant polycystic kidney disease (ADPKD). Our aim was to examine the relationship between serum fibroblast growth factor-23 (FGF-23) levels, left ventricular global longitudinal strain (LV-GLS), arterial stiffness (AS), and carotid intima-media thickness (CIMT) in patients with ADPKD with preserved kidney function. The relationship between albuminuria, AS, LV-GLS, CIMT, 24-hour ambulatory blood pressure measurement, and FGF-23 was examined in 52 normotensive and hypertensive patients with ADPKD and a matched control group of 35 subjects. AS was assesed with brachial-ankle pulse wave velocity, LV-GLS was measured with speckle-tracking echocardiography. FGF-23 was measured with enzyme-linked immunosorbent assay. The microalbumin/creatinine ratio was significantly higher in the ADPKD group than in the control group (p?0.001). Serum FGF-23 levels were similar between the study and control group. LV-GLS value tended to be impaired and CIMT to be higher in the ADPKD group compared to controls (?18.1?±?2.6 vs. -19.4?±?3.1?%, p?=?0.08; 0.75?±?0.1 vs. 0.68?±?0.1 mm, p?=?0.09, respectively). The augmentation index was significantly higher in the ADPKD group than in the control group (26.2?±?12.5 vs. 16.4?±?11.2 mmHg/mmHg, p?=?0.01). Our study supports subclinical impairment in arterial and cardiac functions in the early period of ADPKD. However, none of these factors was found to be associated with serum FGF-23 levels.

In COVID-19-induced acute respiratory distress syndrome, the lungs are incapable of filling with sufficient air, leading to hypoxemia that results in high mortality among hospitalized patients. In clinical trials, low-molecular-weight heparin was administered via a specially designed soft-mist inhaler device in an investigator initiated, single-center, open-label, phase-IIb clinical trial. Patients with evidently worse clinical presentations were classed as the "Device Group"; 40 patients were given low-molecular-weight heparin via a soft mist inhaler at a dose of 4000 IU per administration, twice a day. The Control Group, also made up of 40 patients, received the standard therapy. The predetermined severity of hypoxemia and the peripheral oxygen saturation of patients were measured on the 1st and 10th days of treatment. The improvement was particularly striking in cases of severe hypoxemia. In the 10-day treatment, low-molecular-weight heparin was shown to significantly improve breathing capability when delivered via a soft-mist inhaler.
