Neuropathic pain in axial spondyloarthropathy is underdiagnosed and a confounding factor in biologic drug-switching decision: a cross-sectional study.

OBJECTIVES: The aim of this study was to evaluate the relationship between the presence of neuropathic pain (NeP), disease activity scores and biologic drug-switching decisions in the subjects with axial spondyloarthritis (axSpA) receiving biologic treatment. METHODS: PainDETECT Questionnaire was used to evaluate the presence of NeP in the patients with axSpA aged ≥18 years who had been receiving biologic treatment for at least 6 months. The relationships between disease activity scores, inflammatory markers, life quality index, biologic drug-switching decisions and the presence of NeP were analyzed. RESULTS: A total number of 175 patients with axSpA [ankylosing spondylitis (AS) (n:150) and non-radiographic axSpA (nr-axSpA) (n:25)] were enrolled in the study. NeP was detected in 41.7% of the patients and it was more common in females than in males (p:0.009). PainDETECT scores were positively correlated with disease activity scores, but they were not correlated with inflammatory marker levels. NeP was found to be significantly more common in whom the biologics had been switched 3 or more times (p:0.007). PainDETECT scores were higher and NeP was more prevalent (p:0.028) in the patients for whom drug-switching decisions had been made due to primary or secondary unresponsiveness. CONCLUSION: NeP is more common than estimated in the patients with axSpA and current disease activity scores are insufficient to make a distinction between NeP and inflammatory pain. NeP is a confounding factor in the evaluation of treatment response to biologic agents. In the subjects with AS and nr-axSpA with primary or secondary treatment unresponsiveness, the presence of NeP must be considered before biologic drug-switching decisions. Key Points • Neuropathic pain (NeP) is common in subjects with AxSpA treated with multiple biologic agents. • Current disease activity scores for AxSpA are insufficient to make a differentiation between NeP and inflammatory pain. • NeP is a confounding factor in the evaluation of treatment response to biologic agents. • Patients with AxSpA should be re-evaluated in terms of the presence of neuropathic pain before making biologic drug-switching decisions.

The risk of cancer in patients with primary Sjögren syndrome: a single-center study from Turkey.

BACKGROUND: The aim of this study is to determine the risk of cancer in patients with primary Sjögren syndrome (pSS) from a single center in Turkey. METHODS: Clinical data of the subjects with pSS were retrospectively analyzed. The incidence of cancer for general population was obtained from GLOBOCAN 2018. Age- and sex-specific standardized incidence ratios (SIR) of solid and hematological cancers were calculated compared with the general population. RESULTS: Four hundred thirty patients with pSS were included in the study. The majority of the patients were female (n = 396, 92.1%), and the mean age was 58.6 ± 12.0 years. Thirty-four patients (7.9 %) were diagnosed with cancer (26 solid and 8 hematological) during follow-up. The SIR for all cancers was 2.45 (95% CI, 1.625-3.275). The SIR was 2.42 (95% CI, 1.542-3.298) for solid cancers and 8.42 (95% CI, 2.394 - 14.446) for hematological cancers. The most diagnosed malignancies were breast cancer (n = 6), ovarian cancer (n = 6), and non-Hodgkin lymphoma (NHL) (n = 4). There was an increased risk for ovarian cancer (SIR 12.76, 95% CI, 2.545-22.975). The SIR values were 2.08 (95% CI, 0.419-3.741) and 10.81 (95% CI, 0.216-21.404) for breast cancer and NHL, respectively. DISCUSSION: The risk of hematological and solid cancers was higher in the patients with pSS when compared to general population. In our pSS cohort, the risk for ovarian cancer was found to be increased, which has not been previously reported in the literature.

Does Total Parenteral Nutrition Increase the Mortality of Patients with Severe Sepsis in the ICU?

OBJECTIVES: We aimed to evaluate the independent association between total parenteral nutrition (TPN) and nosocomial infection and intensive care unit (ICU) mortality in patients with severe pulmonary sepsis. MATERIAL AND METHODS: The present study was designed as a retrospective observational cohort study. We enrolled all patients with severe sepsis due to pulmonary infections who stayed more than 24 h in the respiratory ICU between January 2009 and December 2010. We recorded demographic characteristics, ICU severity scores, Acute Physiologic and Chronic Health Evaluation II (APACHE II) and first day Sequential Organ Failure Assessment (SOFA) score in the ICU, TPN because of intolerance to enteral feeding, ICU data, and mortality. To evaluate the risk factors for mortality, we performed adjusted logistic regression test for TPN, nosocomial infection, and SOFA in the model. RESULTS: Five hundred and fifty patients (males=375, females=175) with severe sepsis were involved in the study during the study period. The median and interquartile range (IQR) of age, APACHE II, and SOFA score at the time of admission to the ICU were 65 years (53-73), 20 (16-25), and 4 (3-6), respectively. Mortality rate was 18% (n=99). Adjusted odds ratio (OR), confidence intervals (CI) 95%, and p values of TPN, nosocomial infection, and first day SOFA score for mortality were as follows: OR:3.8, CI:2.3-6.1, p<0.001; OR:2.4, CI: 1.4-3.9, p<0.001; and OR: 1.3, CI:1.2-1.4, p<0.001, respectively. CONCLUSION: Nosocomial infection and the need for TPN because of intolerance of enteral nutrition (EN) is associated with a higher mortality rate in patients with severe sepsis in the ICU. Rational use of antibiotics and application of hospital acquired infection control program will further reduce mortality.

C-reactive protein as a predictor of mortality in patients affected with severe sepsis in intensive care unit.

BACKGROUND: Severe sepsis is a primary cause of morbidity and mortality in the intensive care unit (ICU). Numerous biomarkers have been assessed to predict outcome and CRP is widely used. However, the relevance for mortality risk of the CRP level and the day when it is measured have not been well studied. We aimed to assess whether initial and/or third dayCRP values are as good predictors of mortality in ICU patients with severe sepsis as other well-known complex predictors of mortality, i.e., SOFA scores. METHODS: An observational cohort study was performed in a 20-bed respiratory ICU in a chest disease center. Patients with severe sepsis due to respiratory disease were enrolled in the study. SOFA scores, CRP values on admission and on the third day of hospital stay, and mortality rate were recorded. ROC curves for SOFA scores and CRP values were calculated. RESULTS: The study included 314 ICU patients with sepsis admitted between January 2009 and March 2010. The mortality rate was 14.2% (n = 45). The area under the curve (AUC) for CRP values and SOFA scores on admission and on the 3rd day in ICU were calculated as 0.57 (CI: 0.48-0.66); 0.72 (CI: 0.63-0.80); 0.72 (CI: 0.64-0.81); and 0.76 (CI: 0.67-0.86), respectively. Sepsis due to nosocomial infection, a CRP value > 100 mg/L and higher SOFA scores on 3rd day, were found to be risk factors for mortality (odds ratio [OR]: 3.76, confidence interval [CI]: 1.68-8.40, p < 0.001, OR: 2.70, CI: 1.41-2.01, p < 0.013, and OR: 1.68, CI: 1.41-2.01, p < 0.0001, respectively). CONCLUSIONS: The risk of sepsis related mortality appears to be increased when the 3rd day CRP value is greater than 100 mg/dL. Thus, CRP appears to be as valuable a predictor of mortality as the SOFA score.
