ABSTRACT

OBJECTIVE: The first decision to be made in the case of community-acquired pneumonia (CAP) is whether hospitalization of the patient is mandatory. In this study, we aimed to investigate whether the addition of oxygenation parameters to CURB-65 has diagnostic value in predicting mortality in CAP. PATIENTS AND METHODS: A total of 903 CAP patients were included in the study. Patients with a CURB-65 score of 0 and 1 were classified as Group 1 and patients with a CURB-65 score of 2 or more were classified as Group 2. The prediction of mortality through Pneumonia Severity Index (PSI), CURB-65 and CURBS-65/CURBP-65 with the addition of SaO2 and PaO2 values; hence the four different models, was compared among all patient groups. RESULTS: As a result, 3.3% of the cases in Group 1 and 12.7% of the cases in Group 2 died. In both CURB-65 groups, it was noted that the frequency of patients with SaO2 <90% was significantly higher in the dead group than in the alive patient group (p=0.009 and p=0.001, respectively). In the univariate analysis, PaO2<60, and SaO2<90 were significantly associated with mortality. Model 2 (CURBS-65) and Model 3 (CURBP- 65) were examined, SaO2<90 (OR 2.08) was found to have an effect on death. In predicting mortality by the receiver operating characteristics (ROC) analysis, it was understood that the CURBS-65 score had a slightly higher area under the curve (AUC) value than CURB-65. CONCLUSIONS: As a result, it has been shown that the use of CURBS-65 scoring instead of CURB-65 clinical scoring may be more useful in predicting mortality.

ABSTRACT

Crimean-Congo haemorrhagic fever (CCHF) is a severe human infection which can lead to fatal consequences. Acute CCHF patients were previously shown to exhibit frequencies of regulatory T-cell (Treg) but lower Treg-mediated suppressive activities than the healthy counterparts. This study aims is to investigate the phosphorylation levels of Foxp3 protein (master regulator of Treg cells) in CCHF patients. Blood samples collected from 18 CCHF patients and nine healthy volunteers were used to isolate peripheral blood mononuclear cells (PBMCs). Total and phosphorylated Foxp3 expression levels in the isolated PBMC samples were monitored by western blot and quantified using ImageJ software. Total Foxp3 expression levels in CCHF patients displayed decreasing trend, but not significantly. In contrast, significantly lower expression levels of phosphorylated Foxp3 were reported in CCHF patients. Our results suggest a possible association between Foxp3 dephosphorylation and CCHF pathogenesis. Nevertheless, more studies are required to evaluate the effect of Foxp3 dephosphorylation on Treg function, which would not only help to enlighten the CCHF pathogenesis but also contribute to the development of effective treatment strategies.

ABSTRACT

BACKGROUND: There has been a substantial improvement in classifying patients with primary Sjögren's syndrome (pSS), with the new 2016 ACR/EULAR classification criteria. It was aimed to investigate the potential role of parotid elastography in the classification of patients with pSS, as well as the clinical diagnosis of those who do not otherwise fulfil the criteria. METHOD: This is a cross-sectional analysis of patients with pSS followed up in tertiary out-patient rheumatology clinic. Patients' medical records were retrospectively investigated whether or not clinically diagnosed pSS patients fulfil 2016 ACR/EULAR criteria sets. Elastographic evaluation of parotid and submandibular glands bilaterally was performed when presented for follow-up. Strain ratio, shear wave velocity and Pascal values of the glands were obtained. RESULTS: Clinical data on 179 patients with Sjögren's syndrome were investigated. Ninety-six patients with pSS and 30 gender and age-matched healthy controls were included in the study. Eighty-six percent of the clinically diagnosed patients satisfied the 2016 ACR /EULAR criteria and were considered 'criteria patients', and the remaining were considered 'non-criteria patients'. Both criteria and non-criteria patients had significantly higher parotid strain ratio and submandibular velocity compared with healthy controls (p < 0.001 and p < 0.001 for parotid strain ratio and p < 0.001 and p = 0.016 for submandibular velocity, respectively). Replacing labial gland biopsy findings with parotid strain ratio in the new classification criteria resulted in similar sensitivity and lower specificity, 91.6% and 80%, respectively. CONCLUSION: Parotid shear elastography is an easy and noninvasive method and might be a useful tool for the classification of patients with pSS, especially when labial gland biopsy is not feasible. Key Points • Salivary gland elastography (SGE) is a useful tool for the classification of patients with pSS. • SGE could be performed instead of labial biopsy without changing the diagnostic power of classification criteria.

ABSTRACT

Crimean Congo hemorrhagic fever is a fatal systemic viral infection which is an important health problem in Turkey. Since it leads to diffuse endothelial damage, many complications can be seen during the course of the disease. We report here an atypical presentation of CCHF with acute acalculous cholecystitis and intraabdominal abscess.
