In patients undergoing immunotherapy, the quality of the immune response is reduced, which may negatively affect the efficacy of vaccination. This study was conducted in order to evaluate the efficacy of the hepatitis B virus (HBV) vaccine in patients using immunomodulators. Seronegative patients for HBV who were using biological agents, were included in the study. The vaccination was administered on the standard schedule in 3 doses of 20 or 40 µg/ml. Eighty-two patients (52%) were males and the mean age of all patients was 44,8 ± 10,3 years. Among these 109 patients, 83 had psoriasis, 12 had Crohn’s disease, six had rheumatoid arthritis, three had ulcerative colitis, three had hydradenitis supurativa, one had Behcet’s disease and one had ankylosing spondylitis. The biological agents that were being used by these patients were adalimumab (62), ustekinumab (25), infliximab (12), etanercept (9) and golimumab (1). Seventy-three of the patients were vaccinated with a dose of 20 µg/ml and 36 with 40 µg/ml. The anti-HBs titers of fifty-eight (53.2%) patients were above 10 mIU/ml. The antibody response rate was lowest in infliximab-users (16.7%) (p = 0.007), which was followed by adalimumab (48.4%), and higher protection rates were achieved in patients using ustekinumab and etanercept (72% and 88.9%, respectively; p < 0.05). The HBV vaccine response rate in patients using immunomodulators was significantly lower than that in immunocompetent patients. Furthermore, high dose vaccination did not increase the response rate. Clinicians should take into account administering HBV vaccination before treatment with biological agent in patients who have negative HBV serology.

Background/Objectives: In recent years, inflammatory markers have been increasingly utilized to predict disease prognosis. The neutrophil percentage-to-albumin ratio (NPAR) has emerged as a novel biomarker reflecting inflammation and systemic response. This study was conducted to evaluate the prognostic value of NPAR in pneumonia patients aged 80 years and older hospitalized in intensive care. Methods: Patients aged 80 years and older who were followed up in the intensive care unit with a diagnosis of pneumonia between 1 October 2022, and 31 May 2024, were retrospectively reviewed. Demographic characteristics, laboratory data, disease severity scores (APACHE II, SOFA), intensive care interventions, and variables associated with mortality were analyzed. NPAR was calculated by dividing the neutrophil percentage by the serum albumin level. The prognostic value of NPAR was assessed using Kaplan–Meier survival analysis, receiver operating characteristic (ROC) curve analysis, and Cox regression analysis. Results: A total of 135 patients were included in the study. Patients with NPAR > 0.286 had significantly higher SOFA (p = 0.002) and APACHE II (p = 0.007) scores. The high NPAR group was at significantly greater risk for requiring invasive mechanical ventilation (p = 0.003), vasopressor support (p = 0.042), and developing sepsis (p = 0.035). Elevated NPAR was strongly associated with mortality (p < 0.001) and was identified as an independent predictor of mortality in the Cox regression analysis (HR = 2.488, 95% CI: 1.167–5.302, p = 0.018). Conclusions: NPAR may serve as an effective biomarker for predicting disease severity and mortality risk in pneumonia patients aged 80 years and older. Due to its simplicity and accessibility, it can be considered a practical parameter for integration into clinical practice. However, large-scale, multicenter, and prospective studies are needed to validate these findings.

The demographic shift with an aging population worldwide has highlighted the unique healthcare challenges the elderly face. According to the Turkish Statistical Institute data, the population aged 65 and over reached 8,722,806 in 2023, accounting for 10.2% of the total population. Population projections indicate that the proportion of the elderly population is expected to reach 12.9% in 2030

Objectives: Individuals aged 80 and above, classified as the oldest old, are a growing population frequently requiring intensive care unit (ICU) admissions due to pneumonia. The disease in this group is complicated by comorbidities, immune dysfunction, and antibiotic-resistant infections. This study aimed to identify factors influencing mortality in elderly ICU patients. Materials and Methods: This retrospective study included 135 patients aged 80+ diagnosed with pneumonia in the ICU. Demographic data, clinical findings, laboratory results, and outcomes were analyzed. APACHE-II and SOFA scores were calculated upon admission. One-month in-hospital mortality was the primary endpoint, and predictors of mortality were examined. Results: The average age was 86.87, with a 39.2% mortality rate. APACHE II and SOFA scores were strong predictors of mortality. Factors associated with increased mortality included hemodialysis(p<0.001), invasive mechanical ventilation(p<0.001), low albumin(p=0.006), high procalcitonin(p=0.003), Neutrophil Percentage/Albumin Ratio (NPAR)(p<0.001), urea (p<0.001), and creatinine(p=0.010). Chronic Obstructive Pulmonary Disease (COPD) emerged as an independent risk factor. Conclusions: Mortality in elderly pneumonia patients is multifactorial. APACHE II, SOFA scores, and markers such as NPAR and COPD significantly affect outcomes. These findings underscore the importance of strategies to prevent organ dysfunction, monitor nutritional status, and manage infections in this vulnerable population.
