Effect of serum vitamin D levels on the severity of acute pancreatitis: A prospective study.

Acute pancreatitis (AP) is a serious and complex disorder with varying disease course and severity. Early and prompt interventions are crucial in management of AP. Vitamin D, being a prominent actor in calcium metabolism, also takes part in immunity and thus in immune-system related disorders, ranging from infections to cancer. In this study, the role of vitamin D status of a patient on the severity of AP was investigated. This study was conducted between June 2021 to August 2022 with a total of 315 patients. Blood samples were obtained upon admission. A 25-(OH)D3 level less than 10 ng/ml was defined as vitamin D deficiency. 10-19 ng/ml was defined as vitamin D insufficiency whereas 20 ng/ml or above was considered to be sufficient. Scoring systems (Ranson score, CTSI, BISAP, Revised Atlanta Classification (RAC) were applied. Serum 25-(OH)D3 levels of patients with AP were found to be negatively correlated with severity of the disease according to RAC (p < 0.001). In concordance to this finding, both Ranson score and BISAP were found to be statistically significantly related to 25-(OH)D3 levels. Both scoring systems revealed higher scores in patients with insufficient or deficient levels of 25-(OH)D3. Serum 25-(OH)D3 levels were not found to be related to intensive care unit admission or mortality. This study revealed that serum 25-(OH)D3 level is related to the severity of AP. In the future, interventional studies with vitamin D therapy in otherwise serum 25-(OH)D3 deficient AP patients might reveal a new potential therapeutic agent in this mechanically complex, burdensome disorder.

Importance of target calorie intake in hospitalized patients.

BACKGROUND/AIMS: To evaluate the feasibility and clinical outcome of a nutritional algorithm based on target calorie intake commenced as enteral nutrition (EN) alone or in combination with supplemental parenteral nutrition (SPN) among hospitalized patients. MATERIALS AND METHODS: In total, 301 hospitalized patients who were provided with nutritional support, including EN (n=125) or EN+SPN (n=176), due to various medical conditions during their hospitalization were included in this study conducted at Antalya Training and Research Hospital. All the patients were evaluated during their hospitalization under nutritional support until discharge or in-hospital death. Data on the length of stay (LOS) and serum pre-albumin and C-reactive protein (CRP) levels and records for feeding days considering nutritional risk screening (NRS) 2002 scores were collected. RESULTS: Overall, 85.7% of patients achieved the target calorie intake within a median of 4.0 days, while discharge and in-hospital death rates were 58.1% and 41.9%, respectively. Of the 5719 feeding days recorded during follow-up, 1076 (18.8%) days were associated with failure to achieve the target calorie intake with hemodynamic instability (33.3%), procurement problems (33.3%), and oral reluctance (23.0%). CONCLUSION: Our findings emphasize the role of keeping the intake closer to the target calorie intake and immediate use of SPN whenever full EN fails to achieve the target calorie intake for improving the adequacy of clinical nutrition in the early phase of critical illness. The EN and EN+SPN groups were found to be similar in terms of rates of target achievement, mortality, and discharge, while a lower mortality rate and improved nutritional status were evident in achievers than in non-achievers of the target calorie intake regardless of the type of nutrition.

Assessment of Aortic Elasticity in Patients with Celiac Disease.

BACKGROUND AND OBJECTIVES: Celiac disease (CD) is a chronic autoimmune disorder induced by dietary gluten intake by individuals who are genetically sensitive. Many studies report an increased risk of cardiovascular diseases in such patients. The aim of this study is to assess aortic elasticity properties in patients with CD that may be associated with an increased risk of cardiovascular disease. SUBJECTS AND METHODS: Eighty-one patients diagnosed with CD by antibody test and biopsy and 63 healthy volunteers were included in this prospective study. Electrocardiographic and echocardiographic examinations were performed. RESULTS: The CD group did not have any differences in the conventional echocardiographic parameters compared to the healthy individuals. However, patients in the CD group had an increased aortic stiffness beta index (4.3±2.3 vs. 3.6±1.6, p=0.010), increased pressure strain elastic modulus (33.6±17.0 kPa vs. 28.5±16.7 kPa, p=0.037), decreased aortic distensibility (7.0±3.0×10(-6) cm(2)/dyn vs. 8.2±3.6×10(-6) cm(2)/dyn, p=0.037), and similar aortic strain (17.9±7.7 vs. 16.0±5.5, p=0.070) compared to the control group. Patients with CD were found to have an elevated neutrophil/lymphocyte ratio compared to the control group (2.54±0.63 vs. 2.24±0.63, p=0.012). However, gluten-free diet and neutrophil/lymphocyte ratio were not found to be associated with aortic elasticity. CONCLUSION: Patients with CD had increased aortic stiffness and decreased aortic distensibility. Gluten-free diet enabled the patients with CD to have a reduction in the inflammatory parameters whereas the absence of a significant difference in the elastic properties of the aorta may suggest that the risk of cardiovascular disease persists in this patient group despite a gluten-free diet.

Cirrhotic Ascites management via procalcitonin level and a new approach B-mode gray-scale histogram.

BACKGROUND/AIMS: To determine the role of serum procalcitonin levels and ascites/subcutaneous echogenicity ratio (ASER) in predicting ascites infection in hospitalized cirrhotic patients. MATERIALS AND METHODS: A total of 50 patients hospitalized because of cirrhosis-related ascites were included in this study. In these patients, 44% of ascites were infected (peritonitis), whereas 56% of ascites were sterile. These two groups were compared in terms of procalcitonin levels and ASER for predicting ascites infection. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of ASER, and the predicting outcome of ASER was compared with procalcitonin levels. RESULTS: The ASER values of the patients with the diagnosis of infected ascites were significantly higher than in those with the diagnosis of sterile ascites (p<0.001). ROC analysis was performed to determine the diagnostic ASER value for infected ascites. An ASER greater than 0.0019 determined peritonitis with 95.5% sensitivity and 100% specificity. A procalcitonin level greater than 0.05 determined peritonitis with 86.4% sensitivity and 75% specificity. Using ROC analysis, an ASER greater than 0.0019 [area under curve (AUC): 0.974, 95% confidence interval (CI) (0.884-0.999, p<0.001)] was a significantly better diagnostic marker than a procalcitonin level >0.5 mg/dL [AUC: 0.860, 95% CI (0.884-0.999, p<0.001) (p<0.045)]. CONCLUSION: According to our findings, the determination of ASER and serum procalcitonin levels seems to provide satisfactory diagnostic accuracy in differentiating ascites infections in hospitalized cirrhotic patients. ASER values significantly differentiate ascites infections better than procalcitonin levels.

Helicobacter pylori eradication lowers serum asymmetric dimethylarginine levels.

INTRODUCTION: Microbial pathogens, one of them is Helicobacter pylori (H. pylori), have frequently been implicated in the atherogenesis. Endothelium-derived nitric oxide (NO) is synthesized from L-arginine by nitric oxide synthase (NOS) and plays a pivotal role in the regulation of vascular tone. Asymmetric dimethylarginine (ADMA) is the most potent endogenous NOS inhibitor. Elevated levels of ADMA have been reported in many circumstances associated with a high cardiovascular risk. The aim of the present study was to investigate whether the eradication of H. pylori infection affects serum ADMA levels. MATERIALS AND METHODS: Forty-two H. pylori-positive patients were enrolled in the study. Triple therapy for 14 days were given to all patients. Serum ADMA levels were measured at baseline and 2 months after therapy. RESULTS: Eradication was achieved in 34 (81%) patients. The mean serum ADMA levels before and after therapy were 1, 77 ± 0, 30 and 1, 67 ± 0, 29 ng/mL in the group with H. pylori eradicated and 1, 63 ± 0, 28 and 1, 56 ± 0, 32 ng/mL in the noneradicated, respectively. We detected statistically significant decreased serum ADMA levels after therapy in H. pylori eradicated group. CONCLUSION: These findings have indicated that eradication of H. pylori infection may decrease the risk of atherosclerosis and cardiovascular events.

Isolated bone metastasis in testicular germ cell tumors: a case report and review of the literature.

BACKGROUND: In testicular germ cell tumors (GCT), bone metastases are usually seen late in the disease progress and are almost always associated with involvement of other sites. However, isolated bone metastasis is an extremely rare finding in these patients. CASE REPORT: A 43- year-old man was admitted to the neurosurgery department of our hospital suffering from dysarthria, ataxia, headaches and a progressive swelling above the parietooccipital region of the skull. Radiological, biochemical and pathologic tests showed that the lesion of the skull was an isolated skull metastasis as an initial manifestation of nonseminomatous GCT of the testis. DISCUSSION: When a young patient presents with bone pain or painless swelling, even if it is an unusual site and isolated, testicular GCT should be considered as a differential diagnosis, as these lesions could be the first evidence of metastatic GCT.
