Subclinical Enthesopathy in Psoriasis-An Ultrasonographic Study.

The present study is aimed at assessing the presence and prevalence of subclinical entheseal changes in Psoriasis (PsO) patients using musculoskeletal ultrasonography (US), conjoined with the analysis of possible differences in terms of demographic, clinical, or biological features. We carried out an observational study on 54 patients with PsO and 40 controls. Subclinical enthesopathy, according to OMERACT definitions, was identified in 20 of the psoriasis patients (37.03%), a significantly difference compared to the controls (5 patients; 10.20%). A comparison between US examinations for psoriasis patients and controls indicates that all the examined areas manifested changes in a significantly higher percentage of patients than the controls. The most common structural changes were represented by thickened tendon (85%), calcification (65%), erosions (35%), power Doppler (PD) signal (20%), and bursitis (5%). The difference in mean MASEI (Madrid Sonographic Enthesitis Index) score between the psoriasis and control groups was statistically significant (10.56 + 2.96 vs. 2.9 + 2.20; p < 0.0001). In conclusion, ultrasound is an easily accessible and vital follow-up method for psoriasis patients to enable an early, subclinical detection of entheseal involvement, i.e., the first red-flag sign for a future transition to psoriatic arthritis (PsA).

High mortality risk among women with acromegaly still persists.

Introduction: The mortality ratio in patients with acromegaly has improved over the last few decades. We aimed to determine the mortality rate and correlated factors in patients with acromegaly before and after the introduction of national protocols for treatment. In addition, we determined whether there are sex-related differences in mortality of patients with acromegaly. Methods: This observational retrospective study included 399 consecutive patients with acromegaly between January 2001-December 2022. Paraclinical data included random growth hormone (GH) and insulin-like growth factor-I (IGF1) levels, maximal pituitary tumor diameter at diagnosis, first visit, and last evaluation. Standardized mortality ratio (SMR) was calculated by dividing the observed and expected mortality rates. Cox regression analysis revealed the independent factors associated with mortality. Results: At the last visit, 31.07% (124) of patients were cured, 22.05% (88) had controlled acromegaly with medication, and 45.31% (181) had not controlled acromegaly. During follow-up (13.03 ± 5.65 years, 5216.62 person-years), 89 patients died (0.017%), resulting in an SMR of 1.18 [95% CI 0.95-1.45]. The independent factors associated with mortality were the last IGF1 level/last random GH level, absence of surgery, gonadotropin deficiency, and age. Patients with normal IGF1 after treatment showed an SMR of 0.71, whereas patients with IGF1 ratio > 1 showed SMR=1.51. Patients diagnosed between 1975-2007 and 2008-2022 had SMR = 1.25 [95% CI 0.97-1.58] and SMR = 1.09 [95% CI 0.68-1.65], respectively. In females with acromegaly, SMR was 1.63 [95% CI 1.24-2.11]; 1.76 [95% CI 1.30-2.34] in women diagnosed before 2008 and 1.33 [95% CI 0.69-2.33] in those diagnosed after 2008. Males with acromegaly had a mortality ratio similar to males from the general population (SMR = 0.99, [95% CI 0.66-1.41]). Conclusion: Patients diagnosed with acromegaly in the last 15 years had lower mortality rates than those diagnosed before 2008, due to the availability of new medications, primarily somatostatin receptor analogs and to a higher proportion of patients undergoing surgery. Females still have a high mortality ratio owing to older age at diagnosis and higher risk of metabolic complications. Therefore, efforts should be made for early diagnosis of acromegaly in women.

Preliminary Study on the Antioxidant Effect of Natural Based Products with Potential Application in Complex Regional Pain Syndrome.

Complex regional pain syndrome (CRPS) is a complex condition characterized by chronic pain and various sensory, motor, and autonomic symptoms. It involves a complex interplay of mechanisms in the nervous system, including neuroinflammation, sensitization of pain pathways, and dysfunction of the sympathetic nervous system. Antioxidants may play a role in CRPS by helping to counteract oxidative stress, which is an imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant defences. CRPS involves inflammation and tissue damage, which can lead to increased ROS production and oxidative stress. Our paper represents a preliminary study on various commercially available natural-based products regarding their antioxidant effect. Several natural products with antioxidant properties, such as vitamins C and E, polyphenols, flavonoids, and botanical extracts, have shown promise in preclinical studies for their potential to alleviate pain and reduce inflammation associated with CRPS. The potential use of natural-based products with antioxidant effects for mitigating CRPS symptoms is still an area of ongoing research and investigation, but nonetheless it holds promise.

MMP-13, VEGF, and Disease Activity in a Cohort of Rheumatoid Arthritis Patients.

Identifying certain serum biomarkers associated with the degree of rheumatoid arthritis (RA) activity can provide us with a more accurate view of the evolution, prognosis, and future quality of life for these patients. Our aim was to analyze the presence and clinical use of matrix metalloproteinase-13 (MMP-13), along with vascular endothelial growth factor (VEGF) and well-known cytokines such as tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6) for patients with RA. We also wanted to identify the possible correlations between MMP-13 and these serological markers, as well as their relationship with disease activity indices, quality of life, and ultrasonographic evaluation. For this purpose, we analyzed serum samples of 34 RA patients and 12 controls. In order to assess serum concentrations for MMP-13, VEGF, TNF-α, and IL-6, we used the enzyme-linked immunosorbent assay (ELISA) technique. Our results concluded that higher levels of MMP-13, VEGF, TNF-α, and IL-6 were present in the serum of RA patients compared to controls, with statistical significance. We furthermore identified moderately positive correlations between VEGF, MMP-13, and disease activity indices, as well as with the ultrasound findings. We also observed that VEGF had the best accuracy (97.80%), for differentiating patients with moderate disease activity. According to the data obtained in our study, that although MMP-13, TNF-α and C-reactive protein (CRP) have the same sensitivity (55.56%), MMP-13 has a better specificity (86.67%) in the diagnosis of patients with DAS28(4v) CRP values corresponding to moderate disease activity. Thus, MMP-13 can be used as a biomarker that can differentiate patients with moderate or low disease activity. VEGF and MMP-13 can be used as additional parameters, along with TNF-α and IL-6, that can provide the clinician a better picture of the inflammatory process, disease activity, and structural damage in patients with RA. Our data can certainly constitute a start point for future research and extended studies with multicenter involvement, to support the selection of individualized and accurate therapeutic management strategies for our patients.

Acute gastrointestinal bleeding: A comparison between variceal and nonvariceal gastrointestinal bleeding.

Acute upper gastrointestinal bleeding (UGIB) is a typical medical emergency, with an incidence of 84 to 160 cases per 100,000 individuals and a mortality rate of approximately 10%. This study aimed to identify all cases of UGIB hospitalized in a tertiary gastroenterology department, to identify possible predictive factors involved in rebleeding and mortality, potential associations between different elements and the severity of bleeding, and the differences between the upper digestive hemorrhage due to nonvariceal and variceal bleeding. This was an observational, retrospective study of patients with UGIB admitted to the tertiary Department of Gastroenterology between January 2013 and December 2020. A total of 1499 patients were enrolled in the study. One thousand four hundred and ninety-nine patients were hospitalized for 7 years with active upper digestive hemorrhage, 504 variceal bleeding, and 995 nonvariceal bleeding. When comparing variceal with nonvariceal bleeding, in nonvariceal bleeding, the mean age was higher, similar sex, higher mortality rate, higher rebleeding rate, and higher hemorrhagic shock rate. Endoscopy treatment was also performed more frequently in variceal bleeding than in nonvariceal bleeding. Severe anemia was found more frequently in patients with variceal bleeding. The mortality rate was 10% in the entire study group, which was not significantly different between the 2 batches. However, the rebleeding rate is higher in patients with variceal gastrointestinal bleeding.

Diagnosis of malignant biliary obstruction: pondering over the ERCP, MRCP and histology.

OBJECTIVE: To compare the diagnostic accuracy of endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance pancreatography (MRCP) and histological examination for malignant biliary obstruction. METHODS: This retrospective study included patients admitted for biliary obstruction caused by biliary tree malignancy that underwent ERCP, MRCP and histological examination. Data were collected from the medical records. The primary endpoints were the area under the receiver operating characteristic (AUROC) curve value, sensitivity, specificity and overall diagnostic accuracy of the three procedures in terms of a final diagnosis of obstructive biliary malignancy; and the agreement between ERCP, MRCP and histological examination with the final diagnosis. RESULTS: A total of 160 patients were included in the study (85 males, 53.1%; mean ± SD age, 69.31 ± 10.96 years). Considering the final diagnosis, the performance of MRCP, ERCP and histology in assessing biliary tumours produced AUROC values of 0.88 (95% confidence interval [CI] 0.75, 0.90), 0.94 (95% CI 0.85, 0.99) and 0.80 (95% CI 0.70, 0.82), respectively. ERCP presented higher sensitivity, overall diagnostic accuracy and agreement with the final diagnosis than MRCP and histological examination. CONCLUSION: These current data suggest that invasive methods such as ERCP with biopsy remain more reliable than non-invasive methods.

Opportunistic Colonoscopy Cancer Screening Pays off in Romania-A Single-Centre Study.

Colorectal cancer (CRC) is the third most diagnosed cancer in men (after prostate and lung cancers) and in women (after breast and lung cancer). It is the second cause of cancer death in men (after lung cancer) and the third one in women (after breast and lung cancers). It is estimated that, in EU-27 countries in 2020, colorectal cancer accounted for 12.7% of all new cancer diagnoses and 12.4% of all deaths due to cancer. Our study aims to assess the opportunistic colorectal cancer screening by colonoscopy in a private hospital. A secondary objective of this study is to analyse the adenoma detection rate (ADR), polyp detection rate (PDR), and colorectal cancer (CRC) detection rate. We designed a retrospective single-centre study in the Gastroenterology Department of Saint Mary Hospital. The study population includes all individuals who performed colonoscopies in 2 years, January 2019-December 2020, addressed to our department by their family physician or came by themselves for a colonoscopy. One thousand seven hundred seventy-eight asymptomatic subjects underwent a colonoscopy for the first time. The mean age was 59.0 ± 10.9, 59.5% female. Eight hundred seventy-three polyps were found in 525 patients. Five hundred and twenty-five had at least one polyp, 185 patients had two polyps, 87 had three polyps, and 40 patients had more than three polyps. The PDR was 49.1%, ADR 39.0%, advanced adenomas in 7.9%, and carcinomas were found in 5.4% of patients. In a country without any colorectal cancer screening policy, polyps were found in almost half of the 1778 asymptomatic patients evaluated in a single private center, 39% of cases adenomas, and 5.4% colorectal cancer. Our study suggests starting screening colonoscopy at the age of 45. A poor bowel preparation significantly impacted the adenoma detection rate.

Entheseal involvement in a group of psoriatic arthritis patients: An ultrasonographic study.

Psoriatic arthritis (PsA) is an inflammatory potentially destructive disease that requires early diagnosis and therapeutic approach. Its main pathogenic event and the condition's hallmark is considered to be enthesitis. Clinical examination of the enthesis can be a challenge in the clinical practice; thus, ultrasonography (US) has emerged as an indispensable imaging tool for evaluating both structural and inflammatory changes of this structure. In the present study, we aimed to analyze the type and frequency of entheseal involvement in PsA patients by US examination, performing a retrospective study on 41 patients diagnosed with PsA. Ultrasonographically confirmed enthesitis, identified according to Outcome Measures in Rheumatology group (OMERACT, initially Outcome Measures in Rheumatoid Arthritis Clinical Trials) definitions, was present in 26 of the included patients, Achilles enthesis being the most common site involved. The prevalence of tendon structure abnormalities and the presence of entesophytes underlines the importance of chronic inflammation on entheseal sites. US examination has proven to be a reliable imaging method, with significant and continuous improvement, which is clearly a requisite part for current understanding and diagnosis of enthesitis and more than this, for the patient follow-up algorithm.

Facing the Unseen - Metabolic Syndrome in Psoriatic Arthritis.

Psoriatic arthritis (PsA) is a heterogeneous multifaceted inflammatory artropathy, associated or not with psoriasis, part of the spondyloarthropaties group. Beyond articular and skin manifestations, patients with psoriatic disease are prone to associated comorbidities, including cardiovascular disease (CVD), obesity and metabolic syndrome, diabetes, or fatty liver disease; in order to improve the prognosis and the quality of life for these patients, it is mandatory to prevent, identify and properly manage any of the comorbidities. We aimed to assess the presence of traditional CV risk factors and MetS in a group of PsA patients, compared to controls and their possible inter-relation. We performed an observational study on 41 consecutive patients diagnosed with PsA based on CASPAR established criteria. Our subjects met the criteria of MetS in a percentage of 43.90% of the cases and AHT, frequently reported in higher percentages for PsA or psoriasis patients, compared to general population was also revealed in significant percentages by our data. Regarding dyslipidemia, it is confirmed and validated by several studies that patients diagnosed with PsA or psoriasis associate an altered lipid metabolism and our study noticed data accordingly. As PsA is a condition characterized by chronic inflammation, a non-traditional CV risk factor, each patient should benefit from a periodic close evaluation in order to approach a compete and early therapeutic intervention and reduce further CV morbidity and mortality rates.

New insights into IL-17/IL-23 signaling in ankylosing spondylitis (Review).

Ankylosing spondylitis (AS) is a progressive common autoimmune inflammatory disease, part of the spondylarthritis group, characterized, besides clinical spinal and peripheral joint inflammation, by enthesitis and new bone formation, that can lead to severe functional impairment. Beyond intensive and continuous research on the pathogenic process extensively performed in recent years, their impact on therapeutic management remains open to future development. Better knowledge of AS pathogenesis have shown results progressively and studies are being performed to advance our current understanding of the disease. It is well known that tumor necrosis factor (TNF) exerts a central role, along with interleukin-17 (IL-17) and interleukin-23 (IL-23), demonstrated by several clinical studies. Similar to other rheumatic inflammatory conditions, SA is associated with an early process of systemic bone loss, both trabecular and cortical, consecutive osteopenia, osteoporosis, and high fracture risk. Current personalized therapeutic options benefit from new published data, to prevent future complications and to improve quality of life.

Host immune response in chronic hepatitis C infection: involvement of cytokines and inflammasomes.

Chronic liver disease is a major health issue worldwide and chronic hepatitis C (CHC) is associated with an increased risk of cirrhosis and hepatocellular carcinoma (HCC). There is evidence that the hepatitis C virus (HCV) infection is correlated with immune senescence by way of immune activation and chronic inflammation, which lead to increased metabolic and cardiovascular risk, as well as progressive liver damage. Both the innate and adaptive immunity are firmly tied to the prognosis of an infection with HCV and its response to antiviral therapy. HCV is therefore associated with increased pro-inflammatory status, heightened production of cytokines, prolonged systemic inflammation, as well as increased morbidity and mortality, mainly due to the progression of hepatic fibrosis and HCC, but also secondary to cardiovascular diseases. Viral hepatic pathology is increasingly considered a disease that is no longer merely limited to the liver, but one with multiple metabolic consequences. Numerous in vitro studies, using experimental models of acute or chronic inflammation of the liver, has brought new information on immunopathological mechanisms resulting from viral infections and have highlighted the importance of involving complex structures, inflammasomes complex, in these mechanisms, in addition to the involvement of numerous proinflammatory cytokines. Beyond obtaining a sustained viral response and halting the aforementioned hepatic fibrosis, the current therapeutic "treat-to-target" strategies are presently focused on immune-mediated and metabolic disorders, to improve the quality of life and long-term prognosis of CHC patients.

The role of skin and muscle biopsy in the diagnosis of main connective tissue diseases.

Systemic involvement in autoimmune diseases is often unclear and organ changes are confounding, thus making it difficult to have an early accurate diagnosis. In those situations, both clinical and paraclinical findings might orientate the diagnosis, but only histological or immunohistochemistry changes might be accurate enough. The skin histological changes are relevant and sometimes might have a tremendous role in the accurate diagnosis of autoimmune rheumatic diseases, due to the correlation with the clinical systemic manifestations of the diseases and through the accessibility of biopsy. In the same time, muscle biopsy can provide important support for physicians improving diagnosis and optimizing management of connective tissue diseases.

Intramuscular hemangioma of the arm: ultrasonography and pathology features.

Hemangiomas are between the most frequent soft tissue masses and despite the vascular origin, they do not generate metastases and do not have malignant evolution. They are frequent in childhood and female sex is more frequently affected. If deeply located, these tumors are difficult to diagnose and thus an imaging method is often needed, but conventional radiology is not sufficient. If superficially located, it frequently involves the skin and subcutaneous tissues, but in the deeper layer, they are often intramuscular. Clinical findings of intramuscular hemangioma include swelling, pain and sometimes loss of muscle function.

Vascular endothelial growth factor in systemic lupus erythematosus - correlations with disease activity and nailfold capillaroscopy changes.

Our study aimed to quantify serum VEGF (vascular endothelial growth factor) and its inter-relation with the severity of microvascular damage, assessed by nailfold capillaroscopy (NC), and to establish the possible relationship with disease activity score. We included 18 patients, diagnosed with systemic lupus erythematosus (SLE) and 17 gender and age-matched control subjects. For determining serum VEGF, we used a Human VEGF Assay kit-IBL. NC was performed, according to the standard method, using a video-capillaroscope Videocap 3.0, DS Medica, by the same examiner, blinded to clinical and laboratory data. Serum VEGF registered a mean value of 68.99±71.06 pg/mL for SLE patients and 31.84±11.74 pg/mL for controls, differences statistically significant; depending on disease activity, we found a mean value of 60.11±57.74 pg/mL, for patients with moderate disease activity vs. 30.96±11.51 pg/mL for the ones with a low activity (p=0.014). We found a moderately positive correlation, statistically significant (p=0.015), between serum level of VEGF and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Performing NC, we found changes in 88.88% of the patients; the most frequent were increased tortuosity, dilated capillaries, an increased length and a prominent subpapillary plexus. The presence of nailfold capillaroscopy changes and serum level of VEGF, correlated moderately, positive. Since serum levels of VEGF are higher in SLE patients, compared to controls, significantly different according to disease activity degree, and directly inter-related to abnormal NC patterns and a more active disease, we can include these accessible parameters in the routine evaluation, in order to better quantify the systemic damage, individualize the treatment, improve the outcome and life quality for these patients.
