High mobility group box-1 levels may be associated with disease activity of Behcet's disease

BACKGROUND: High mobility group box- 1 (HMGB- 1) is a nuclear protein acting as a proinflammatory molecule. The serum HMGB- 1 levels were found elevated in chronic inflammatory diseases. In this cross-sectional study, serum HMGB- 1 levels in Behcet's disease (BD) patients and healthy controls (HC) were studied. Also, its association with disease activity scores and clinical findings were evaluated. METHODS: Ninety BD patients and 50 age-sex matched HC were included in the study. Disease activity scores were assessed by Behcet Disease Current Activity Form (BDCAF) and Behcet Syndrome Activity Score (BSAS). Serum HMGB- 1 levels were measured using a commercial ELISA kit. A p value of < 0.05 was considered to be statistically significant. RESULTS: Serum HMGB- 1 levels were significantly higher in BD than in HC (43.26 pg/mL and 16.73 pg/mL; p < 0.001, respectively). Serum HMGB- 1 levels were statistically significantly associated with presence of erythema nodosum (EN) and genital ulcers in the last one month prior to recruitment (p = 0.041 and p < 0.001, respectively). BDCAF and BSAS scores were positively correlated with serum HMGB- 1 level ( p = 0.03 and p = 0.02, respectively). DISCUSSION: HMGB - 1 may play a role in the development of BD. Also, due to its positive correlation with disease activity indices, it can be used as a novel disease activity parameter in BD.

Acute stunning effect of hemodialysis on myocardial performance: A three-dimensional speckle tracking echocardiographic study.

The effects of acute changes during hemodialysis (HD) on the myocardium are not yet known. The invention of three-dimensional speckle tracking echocardiography (3DSTE) has offered clinicians a new method to assess the movements of ventricular segments simultaneously in three spatial directions. The aim of this study was to evaluate the effect of first weekly standard HD process on the left ventricle (LV) and right ventricle (RV) global and regional myocardial function in patients with normal left ventricle ejection fraction using 3DSTE-derived indices. Patients (n=38) receiving maintenance HD in our clinic who have no known cardiovascular disease are examined just before and after a HD session using 3DSTE. Demographic and comorbidity data, renal replacement treatment characteristics, and laboratory test results are recorded. 3DSTE analysis is performed to calculate the LV global longitudinal, circumferential area and radial peak systolic strain, as well as RV septum and free-wall longitudinal strain and fractional area change. Patients are aged 52.8 ± 13.6 years and 52.6% of them are male. Mean dialysis duration is 56 months. The LV strain values of the patients changed markedly before and after HD (GLS: -14.2 ± 5.2, -11.1 ± 4.6 [P < .001], GCS: -14.8 ± 4.2, -12.4 ± 5.28 [P < .009]; GRS: 41.5 ± 16, 33.3 ± 16.5 [P = .003]; AREA -24.7 ± 7.2, -20.1 ± 7.6 [P = .001], respectively). We could not demonstrate any improvement in RV strain values before or after HD. LV strain values are positively correlated with blood pressure variability during the dialysis sessions. LV function is preserved better after HD in patients on beta or calcium channel blocker therapy compared to those who do not use these agents (P < .001, P < .01, respectively). HD treatment results in deterioration in all LV strain directions but not in RV. Strain assessment may improve vascular risk stratification of patients on chronic HD.

Prognostic value and morphological findings of overexpression of glypican-3 in hepatocellular carcinoma.

OBJECTIVES: Hepatocellular carcinoma (HCC) is the seventh most common cancer all worldwide and is second in cancer-related deaths. In HCC, whose prognosis is still not good despite current treatments, there is a need for prognostic markers as well as early diagnosis. Glypican (GPC)-3 has been proposed as a potential serologic and histochemical marker specific to HCC. This study aimed to determine the relationship between GPC3 overexpression and HCC prognosis and clinicomorphologic features. MATERIALS AND METHODS: In total 152 patients who were diagnosed as a result of hepatectomy, lobectomy or liver transplantation were enrolled. The patients were divided into two groups, GPC3-positive (overexpression) (>10%) and GPC3-negative (<10%). The demographic data of the patients, tumor characteristics and survival times were recorded. RESULTS: Survival was significantly lower in the GPC3+ group. In the multivariate analysis, hepatitis C, AFP, tumor number, tumor focality, portal vein tumor thrombosis and GLP3 positivity were found to be independent risk factors for survival. CONCLUSION: Our study shows that GPC3 overexpression is a poor prognostic factor in HCC. GPC3 positivity were found to be an independent risk factor for survival.

Prognostic factors of elderly patients with hepatocellular carcinoma: should we be more courageous in treatment?

OBJECTIVES: Hepatocellular carcinoma (HCC) is a cancer with a poor prognosis, its incidence increases with age. The risk of developing HCC is highest in the seventh decade. In this study, we aimed to determine the clinicopathological differences, treatment choices, survival times, and effective prognostic factors of HCC in the elderly and young populations. METHODS: All patients aged ≥18 years who were diagnosed histologically between 2016 and 2020 were included in the study. Patients were divided into two groups: <70 years and ≥70 years. The clinicopathological differences, treatment choices, survival times, and effective prognostic factors of HCC were compared in the elderly and young populations. RESULTS: A total of 407 patients were evaluated. There were 164 patients (40.3%) in the geriatric age group. There was no significant difference in the female/male ratio, the laboratory values, survival time between the two groups. There was no significant difference between the two groups in terms of tumor focality and portal vein invasion ( P > 0.05). The presence of NAFLD, maximal tumor diameter (MTD), and portal invasion were found to be significant for survival according to the univariate analysis in elderly group ( P < 0.05). In the multivariate analysis, presence of NAFLD etiologically, and MTD independent risk factors were observed in elderly group ( P < 0.05). CONCLUSION: If the clinicomorphological features of the tumor and prognostic risk factors can be determined by examining the patients in detail, all treatments can be easily applied in the geriatric group.
