Background and Objectives: Psoriasis is a chronic immune-mediated inflammatory disease requiring reliable diagnostic and monitoring tools. Salivary interleukins have emerged as promising non-invasive biomarkers, reflecting systemic inflammation and offering practical advantages such as ease of collection and improved patient compliance. Materials and Methods: This review synthesizes the current evidence on key salivary cytokines—IL-1β, IL-6, TNF-α, and IL-17—in relation to psoriasis pathogenesis, diagnosis, and treatment monitoring. It also compares saliva to blood-based diagnostics, emphasizing benefits like cost-effectiveness and suitability for repeated sampling. Methodological challenges, including heterogeneity in collection protocols and limited longitudinal data, are critically examined. Results: Advances in biologic therapies have deepened the understanding of psoriasis immunopathogenesis, highlighting interleukins as central biomarkers. Recent findings identify IL-37 and IL-38 as novel regulatory cytokines with anti-inflammatory roles. While elevated serum TNF-α levels in psoriatic patients are well documented, some inconsistencies persist. Notably, saliva has proven to be a viable alternative diagnostic fluid, supporting large-scale screening and routine clinical monitoring. Conclusions: Salivary interleukins—particularly IL-1β, IL-6, TNF-α, and IL-17—represent valuable, non-invasive biomarkers for early detection, disease severity assessment, and therapeutic response monitoring in psoriasis. Standardizing saliva-based methods and conducting large-scale studies are essential next steps to support their integration into personalized clinical practice.

Background and Objectives: Hematological disorders, especially chronic anemia and coagulation disorders, are common in patients with chronic kidney disease (CKD). Severe anemia is associated with increased cardiovascular morbidity and mortality in this special group of patients and is also responsible for decreased hope and quality of life. Despite the use of appropriate iron therapy and erythropoietin-stimulating agents, red blood cell transfusion is occasionally required, usually in the setting of acute bleeding or for correction of perioperative anemia. The COVID-19 pandemic has accelerated the progression of chronic diseases and worsened the outcomes for patients with nephrological conditions. As a precautionary measure against infections, patients’ access to hospitalization for their procedures has been reduced and their chronic complications, including hematological abnormalities, have gotten out of control. Materials and Methods: Our retrospective observational study was designed to evaluate the impact of the COVID-19 pandemic on blood transfusion for the patients with chronic kidney disease hospitalized in our emergency county medical unit, over a period of four years (2019–2022) who were admitted or at least referred for evaluation to the Nephrology department. We also followed the measures adopted to ensure the necessary blood products during this time. Results: Between 2190–2022, a total of 24,096 hospitalized patients were transfused at the Emergency County Clinical Hospital in Constanta, Romania. Meanwhile, in the nephrology and other medical or surgical wards of our medical unit, 1590 CKD patients were transfused with different blood derivatives. During the pandemic years, as expected, the number of transfused patients and transfused blood units decreased by 4% and 7%, respectively, in comparison with the pre-pandemic year, 2019. Unlike the general trend of transfusion activity, more patients with CKD transfused in 2022 (580) than before the pandemic (414 in 2019), and the number of blood units was higher in 2022 than in 2019 for red blood products and plasma. Between 2020–2022, from the total number of transfused patients in our study, 254 with CKD patients (16%) and 798 non-CKD (4%) died in-hospital. Conclusions: The adaptive strategies implemented to ensure the necessary blood products in the hospital during the COVID-19 pandemic mainly included restrictive transfusion and limitation of elective surgical procedures. The subject matter of the article is important as blood shortages are a problem that healthcare workers may encounter in future pandemics.

There have been relatively few studies revealing a decreased platelet count in chronic kidney disease (CKD). Although this hematological abnormality is not as well documented as renal anemia, platelet functions are altered in the uremic environment and there is an increased risk of bleeding. The aim of this study was to assess the effectiveness of the administration of platelet concentrate in CKD based on how patient prognosis was influenced by platelet transfusion therapy. The study monitored 104 patients with CKD and thrombocytopenia who received platelet transfusion during their hospitalization in the period from 2015 to 2021. The complete blood cell count, serum urea and creatinine, and inflammatory status were tested upon admission. The number of transfused platelet units were considered for each patient. A Kruskal–Wallis H test showed that for one transfused platelet unit, the distribution of the number of platelets (×10³/µL) was the same across the categories of associated diagnoses, which was seen as possible risk factors for thrombocytopenia, including liver cirrhosis and urosepsis. With a single exception, all patients exceeded the critical threshold of 20 × 10³/µL and 14 patients remained under 50 × 10³/µL. Even though our patients exceeded the critical threshold of platelet numbers, in patients with multiple comorbidities, severe, uncontrolled hemorrhages could not be prevented in 4.83% of cases.

Background/Objectives: Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Identifying reliable biomarkers that reflect the underlying immune pathophysiology of sepsis and support early risk stratification remains a major clinical priority. This prospective study aimed to evaluate the prognostic value of interleukin-6 (IL-6) measured at ICU admission in patients with sepsis and septic shock. Methods: This prospective observational study included adult patients with sepsis and septic shock admitted to the Intensive Care Unit (ICU) of the Clinical Hospital of Infectious Diseases Constanța between 2021 and 2025. Receiver operating characteristic (ROC) curve analysis with DeLong comparisons, Kaplan–Meier survival analysis, and Cox proportional hazards regression modeling were performed to assess the association between baseline IL-6 levels, in-hospital mortality, and time to death. Results: Among the analyzed biomarkers, IL-6 demonstrated the highest discriminatory performance for in-hospital mortality (AUC = 0.956; 95% CI: 0.893–0.987; p < 0.0001). The optimal cut-off value (>135.14 pg/mL) yielded a sensitivity of 87.65% and specificity of 92.86% (Youden index = 0.805). However, despite this excellent discrimination between survivors and non-survivors, baseline IL-6 levels were not significantly associated with time-to-death in Cox proportional hazards regression analysis. Conclusions: Admission IL-6 showed excellent discriminatory performance for mortality risk stratification but was not associated with survival duration in time-to-event analyses. These findings suggest that IL-6 should be interpreted primarily as an early risk stratification biomarker rather than a predictor of survival duration in patients with sepsis.

Background: Myocardial ischemia remains a major cause of morbidity and mortality worldwide. Although traditional risk factors are well-established, genetic predisposition—particularly involving MTHFR polymorphisms—has garnered increasing attention. This study investigates the association between MTHFR C677T and A1298C polymorphisms and first-episode myocardial ischemia in a Romanian population. Methods: This study included 69 adult patients with first-episode myocardial ischemia and 55 healthy controls, matched by age and sex. Participants were recruited from southeastern Romania between 2023 and 2025. Clinical data—such as blood pressure, body mass index, smoking, and alcohol consumption—were recorded. Genotyping for MTHFR C677T and A1298C polymorphisms was performed using a real-time PCR-based assay (Bosphore^® MTHFR 677-1298 Detection Kit v2), following the manufacturer’s protocol. Results: A significantly higher frequency of homozygous mutant genotypes was observed in patients with myocardial ischemia. The TT genotype of MTHFR C677T was present in 71% of patients, compared to only 7.3% of controls. Similarly, the CC genotype of A1298C was detected in 59.4% of patients, versus 7.3% in controls. These genotypic patterns suggest a strong genetic predisposition among affected individuals. The association between MTHFR polymorphisms and myocardial ischemia was particularly evident in participants over 50 years of age, indicating a possible interaction between genetic vulnerability and age-related cardiovascular risk. Conclusions: Our findings indicate a strong association between MTHFR C677T and A1298C homozygous mutant genotypes and the risk of first-episode myocardial ischemia, particularly in older adults. These results underscore the potential role of genetic screening in early cardiovascular risk stratification.

Background: Urinary tract infections (UTIs) are a major source of antibiotic use, with increasing antimicrobial resistance compromising treatment efficacy. This study evaluates local pathogen distribution and resistance patterns to support empirical therapy. Methods: We conducted a retrospective, observational study analyzing all positive urine cultures obtained in a tertiary care hospital between January 2023 and December 2025. Bacterial identification and antimicrobial susceptibility testing were performed using routine microbiological methods. Susceptibility results were interpreted according to European Committee on Antimicrobial Susceptibility Testing (EUCAST) criteria. Results: A total of 1,298 bacterial isolates recovered from positive urine cultures obtained between January 2023 and December 2025 were included in the analysis. Antimicrobial resistance was assessed using 18,079 individual antimicrobial susceptibility test (AST) results. Gram-negative bacteria predominated, with Escherichia coli (44.5%) and Klebsiella pneumoniae (20%) accounting for approximately 64.5% of all isolates. E. coli exhibited high resistance rates to ampicillin (60.4%) and trimethoprim–sulfamethoxazole (33.8%), while resistance to fluoroquinolones was considerable (25.9%). In contrast, nitrofurantoin (2.0%) retained excellent activity, and carbapenem resistance remained very low (0.4%). Klebsiella pneumoniae demonstrated extremely high resistance to beta-lactams and fluoroquinolones, with resistance to third-generation cephalosporins exceeding 60% and carbapenem resistance reaching 34.5–41.2%. Among Gram-positive pathogens, Enterococcus faecalis showed high resistance to fluoroquinolones and high-level aminoglycosides, whereas susceptibility to nitrofurantoin, linezolid, tigecycline, and glycopeptides remained largely preserved. The prevalence of vancomycin-resistant Enterococcus (VRE) was low (7.9%). Conclusions: Our findings reveal alarmingly high resistance rates among major pathogens, particularly Klebsiella pneumoniae, significantly limiting empirical therapeutic options. Nitrofurantoin remained highly active in our cohort. In accordance with current international guidelines, nitrofurantoin and fosfomycin remain recommended first-line agents for uncomplicated UTIs. Continuous local surveillance is essential to guide empirical therapy and support antibiotic stewardship efforts.
