Investigation on the relationship between serum periostin, MMP-7, TGF-ß, and IL-18 levels and the clinical course and prognosis of COVID-19.

OBJECTIVE: Cytokines are involved in the inflammatory/anti-inflammatory balance and have been shown to play an important role in the course of COVID-19. This study aimed to evaluate the relationship of periostin, transforming growth factor-beta (TGF-ß), interleukin-18 (IL-18), and matrix metalloproteinase 7 (MMP-7) levels with clinical course and mortality in patients with early COVID-19 pneumonia. PATIENTS AND METHODS: A total of 150 hospitalized patients were diagnosed with COVID-19 between June and October 2021, and a control group of 30 healthy individuals were included in our study. The COVID-19 patients were divided into those who developed macrophage activation syndrome (MAS) in Group 1 and those who did not in Group 2. Serum periostin, MMP-7, TGF-ß, and IL-18 levels were measured from blood samples obtained at admission using enzyme-linked immunosorbent assay (ELISA). RESULTS: Periostin, MMP-7, and IL-18 levels were significantly higher in COVID-19 patients compared to the control group (p<0.001 for all). Periostin and MMP-7 levels were also significantly higher in Group 1 than in Group 2 (p<0.001 for both). Periostin, MMP-7, IL-18, and TGF-ß levels were significantly higher in non-surviving patients compared to survivors (p=0.04, p<0.001, p<0.001, and p<0.001, respectively). In the receiver operating characteristic (ROC) curve analysis, MMP-7 was found to have high sensitivity (90%) at a predictive value of 2.66 ng/mL. CONCLUSIONS: It is still not possible to predict which patients with early COVID-19 pneumonia will go on to develop MAS despite receiving standard treatment. The results of our study suggest that elevation of periostin and MMP-7 levels in the early period may predict the development of macrophage activation syndrome.

Patients with psoriasis have an increased amount of epicardial fat tissue.

BACKGROUND: Psoriasis is associated with coronary artery disease, and ischemic heart disease is associated with increased amounts of epicardial fat tissue (EFT). There has as yet been no study published on the accumulation of EFT in patients with psoriasis. AIM: To compare epicardial fat accumulation and coronary artery calcium score (CACS) in patients with psoriasis and controls. METHODS: We enrolled 38 patients with psoriasis and 38 controls matched for age and gender. Epicardial fat area (EFA) and CACS were evaluated by multidetector computed tomography. RESULTS: Mean EFA in patients with psoriasis was significantly higher than in controls (13.8 ± 8.4 vs. 9.7 ± 6.4 cm(2) , respectively, P = 0.02), but mean CACS did not differ significantly between the two groups (55.2 ± 65.4 vs. 27.8 ± 29.3; P > 0.05). Multiple linear regression analyses indicated that EFA was significantly associated with waist circumference and presence of coronary artery calcification in both patients and controls, whereas EFA was significantly associated waist circumference and age in patients only (P < 0.05). CONCLUSIONS: Patients with psoriasis had a higher level of EFA compared with controls, and EFA was independently associated with the presence of CAC in all study subjects.

Increased carotid artery intima-media thickness and impaired endothelial function in psoriasis.

BACKGROUND: Psoriasis is associated with an increased risk of atherosclerosis. This study compared subclinical atherosclerosis of the carotid and brachial arteries in psoriasis vulgaris patients and healthy controls using high-resolution ultrasonography. METHODS: We studied 43 psoriasis patients and 43 healthy controls matched for age and sex. Flow-mediated dilatation (FMD) and nitroglycerin-induced dilatation (NTD) of the brachial artery and intima-media thickness (IMT) of the common carotid arteries (CCA) were measured ultrasonographically. Diabetes mellitus, hypertension, renal failure, a history of cardiovascular or cerebrovascular disease were exclusion criteria. Subjects who were receiving lipid-lowering therapy, antihypertensive or anti-aggregant drugs, nitrates or long-term systemic steroids were also excluded. RESULTS: The mean IMT values of the right, left and averaged CCA of the psoriasis patients were significantly higher, compared with the controls (0.607+/-0.144 mm vs. 0.532+/-0.101 mm, 0.611+/-0.157 mm vs. 0.521+/-0.117 mm, and 0.609+/-0.146 mm vs. 0.526+/-0.104 mm; P=0.006, P=0.003 and P=0.003, respectively). The mean FMD and NTD values of the psoriasis patients were significantly lower, compared with the controls (13.36+/-6.39 mm vs. 19.60+/-11.23 mm and 21.08+/-8.38 mm vs. 26.85+/-12.38 mm; P=0.002 and P=0.013, respectively). Multiple linear regression analysis revealed a significant association between psoriasis and the IMT, FMD and NTD. Moreover, the FMD in psoriasis patients was associated with disease duration. CONCLUSION: Psoriasis patients had impaired endothelial function and thicker IMT of the CCA, compared with the healthy control subjects. The presence of psoriasis was an independent risk factor for subclinical atherosclerosis.

Broken stent in oesophageal malignancy: a rare complication.

Metallic expandable stents are used increasingly for palliative treatment of inoperable malignant tumours of oesophagus to improve dysphagia. We report a rare case of oesophageal stent fracture that was broken and left in situ within the stomach uneventfully until the end of the patient's life after the application of another stent.
