RESUMO

Inflammatory cardiomyopathy diagnosed by endomyocardial biopsy (EMB) is common in non-ischemic heart failure (HF) and might be associated with adverse outcome. We aimed to identify markers predicting myocardial inflammation in HF. We screened 517 patients with symptomatic non-ischemic HF who underwent EMB; 397 patients (median age 54 [IQR 43/64], 28.7% females) were included in this study. 230 patients were diagnosed with myocardial inflammation, defined as ≥ 7.0 CD3+ lymphocytes/mm2 and/or ≥ 35.0 Mac1 macrophages/mm2 and were compared to 167 inflammation negative patients. Patients with myocardial inflammation were more often smokers (52.4% vs. 39.8%, p = 0.013) and had higher C-reactive protein (CRP) levels (5.4 mg/dl vs. 3.7 mg/dl, p = 0.003). In logistic regression models CRP ≥ 8.15 mg/dl (OR 1.985 [95%CI 1.160-3.397]; p = 0.012) and Troponin I (TnI) ≥ 136.5 pg/ml (OR 3.011 [1.215-7.464]; p = 0.017) were independently associated with myocardial inflammation, whereas no association was found for elevated brain natriuretic peptide (OR 1.811 [0.873-3.757]; p = 0.111). In prognostic performance calculation the highest positive predictive value (90%) was detected for the combination of Global longitudinal strain (GLS) ≥ -13.95% and TnI ≥ 136.5 pg/ml (0.90 (0.74-0.96)). Elevated CRP, TnI and GLS in combination with TnI can be useful to detect myocardial inflammation. Smoking seems to predispose for myocardial inflammation.

RESUMO

Chronic infantile neurological cutaneous and articular syndrome (CINCA) is a disorder with a defect in the CIAS1 (NLRP3) gene and the altered gene product cryopyrin leads to inflammasome activation with increased IL-1beta synthesis. The activation pathway of the transcription factor NF-κB is also affected, which plays a role in angiogenesis. With respect to the angiogenesis stimulating ability of prostaglandin E1, we treated a female patient with CINCA syndrome and conventionally non-responsive skin ulcers with prostaglandin E1 infusions (6 µg/kg bw/24 h/5 day) followed by wound healing lasting over 3 weeks. After 1 year of periodic infusions, the skin defects were permanently closed.

RESUMO

BACKGROUND: Pharmacotherapy for peritoneal adhesion prophylaxis has been a focus for intensive research. Previous strategies included intravenous and intraperitoneal application of suitable pharmaceutical agents. However, success of these strategies in humans has been limited. Here we describe intra-operative local injection of pharmaceuticals as a novel strategy for adhesion prophylaxis. METHODS: N=208 peritoneal lesions were created in 26 adult Wistar rats. In each animal, lesions on one flank were randomly chosen for treatment with locally injected prednisolone whereas the contralateral side was injected with normal saline. Half of the animals were randomly selected for early adhesion scoring after 3 days. Adhesions were scored after 10 days in the other animals. RESULTS: One animal randomized into the late group died peri-operatively. In the early analysis group, 27% (14/52) of treated lesions were affected by adhesions, whereas 50% (26/52) of control lesions were affected by adhesions. This difference was statistically significant (p=0.02). In the late analysis group, 52% (25/48) of treated lesions were affected by adhesions, whereas 60% (29/48) of control lesions were affected by adhesions. This difference did not reach statistical significance. CONCLUSIONS: These experiments provide proof of principle that intra-operative local injection of pharmaceutical agents is a promising strategy for adhesion prophylaxis. Once sutiable agents become available this could become as common as local anesthesia for pain reduction. However, the effect of injected prednisolone diminishes before the vulnerable time-frame for adhesion formation closes. Therefore slow-release formulations and other agents with longer effect will need to be investigated in the future.

RESUMO

BACKGROUND: Since the rate of histologically 'negative' appendices still ranges between 15 and 20%, appendicitis in 'borderline' cases remains a challenging disease. As previously described, cell adhesion molecule expression correlates with different stages of appendicitis. Therefore, it was of interest to determine whether the 'negative' appendix correlated with the absence of E-selectin or vascular cell adhesion molecule-1 (VCAM-1). METHODS: Nineteen grossly normal appendices from a series of 120 appendectomy specimens from patients with suspected appendicitis were analysed in frozen sections for the expression of E-selectin and VCAM-1. As control, 5 normal appendices were stained. RESULTS: This study showed a coexpression of E-selectin and VCAM-1 in endothelial cells in early and recurrent appendicitis. In patients with symptoms for less than 6 h, only E-selectin was detected. Cases with fibrosis and luminal obliteration were only positive for VCAM-1. In cases of early appendicitis with symptoms of less than 6 h duration, a discordance between histological and immunohistochemical results was found. CONCLUSIONS: This report indicates that E-selectin and VCAM-1 expression could be useful parameters in the diagnosis of appendicitis in borderline cases.
