Naples prognostic score may predict overall survival in metastatic pancreatic cancer.

INTRODUCTION: Naples prognostic score (NPS) based on nutritional and inflammatory parameters can predict response to chemotherapy and overall survival (OS) in many cancer types. However, its significance in metastatic pancreatic cancer (PC) remains unclear. We evaluated the prognostic significance of the NPS in patients with metastatic PC receiving first line chemotherapy. METHODS: We retrospectively analyzed 215 patients with metastatic PC receiving first line FOLFIRINOX chemotherapy. NPS's were calculated using pre-chemotherapy laboratory data. Patients were divided into three groups according to their scores (NPS: 0; 1 & 2; 3 & 4 were grouped as 1, 2 and 3, respectively). The association of NPS with clinicopathological features and OS were evaluated. RESULTS: Median age was 64 years, and median OS was 10.5 months. Hemoglobin levels were lower and Ca-19-9 values were higher with increasing NPS. Frequency of patients with bone and/or liver metastases, and with greater than 5 metastatic focus were higher in group 3. A lower NPS was associated with longer OS. The median OS in groups 1, 2, and 3 were 19.5, 12, and 8 months, respectively, and differed significantly. Univariate analysis revealed effect of NPS (3-4) on OS (HR: 2.38, 1.77-3.19). Other prognostic factors affecting OS were age, ECOG, liver, bone or lymph node metastases, number of metastatic foci (<5 vs >5), de-novo metastatic disease, and serum Ca-19-9 levels. NPS (3-4) was identified as an independent prognostic factor negatively affecting OS (HR: 1.89, 1.34-2.65) in multivariate analysis. CONCLUSION: NPS may be a useful prognostic marker for the prediction of OS in metastatic PC patients receiving systemic chemotherapy.

The relationship between DNA mismatch repair gene and other prognostic parameters in pancreatic adenocarcinoma.

The aim of the study was to determine DNA mismatch repair (MMR) proteins by immunohistochemically using MLH1, MSH2, MSH6, and PMS2 antibodies in patients diagnosed as pancreatic ductal adenocarcinoma and to assess its relationship with histopathological and clinical prognostic parameters. Fifty cases with a diagnosis of pancreatic ductal adenocarcinoma who underwent surgical resection, were included in the study. Demographic and histopathological features of the patients were collected from the medical records. The relationships between microsatellite status and prognostic parameters were determined. The mean age of the patients was 66.5 ± 9.5 years (range: 47-87) and male/female ratio was 1.63 (31/19). No errors were detected in DNA MMR proteins in any of the cases, and were classified as microsatellite stable. The mean tumor diameter was 4.01 ± 1.77 cm and 74% of the tumors were localized in the pancreatic head. All of the cases had lymphatic invasion, whereas vascular invasion was detected in only 78% and perineural invasion in 98% of the patients. When the relationship between prognostic parameters and survival was evaluated, statistically significant correlation was observed in patient age and histopathological parameters such as tumor diameter, status of surgical margins, and vascular invasion (p < 0.05). Age, tumor size, presence of tumor at surgical margins, vascular invasion, and adjuvant treatment were correlated with survival. Although microsatellite instability was not detected in our cases, it is important to determine the microsatellite status by immunohistochemistry for predicting the chemotherapy response and determining the immunotherapy option in pancreatic adenocarcinomas.

NT-proCNP levels predict higher atherosclerotic cardiovascular risk profile in patients with proliferative diabetic retinopathy.

AIMS: In this study, we aimed to demonstrate the effectiveness of serum amino-terminal proCNP (NT-proCNP) levels in predicting coronary heart disease (CHD) and cardiovascular risk in type 2 diabetes mellitus (T2DM) patients. METHODS: We recruited 73 patients with T2DM in the study. Additionally, we grouped the patients according to their status of diabetic retinopathy (DR) as no DR, non-proliferative DR, or proliferative DR. Serum NT-proCNP levels of the patients were measured and their atherosclerotic cardiovascular disease (ASCVD) risk scores were calculated. RESULTS: There was no significant difference in terms of NT-proCNP levels between the groups (p = 0.3) and in terms of CHD and ASCVD risk scores (p = 0.4 and p = 0.4, respectively). In the correlation analysis, a significant correlation was observed between the NT-proCNP levels and the ASCVD risk score (r = 0.373; p = 0.008 among the entire cohort and r = 0.555; p = 0.01 in the non-proliferative-DR group), smoking status (r = 0.280; p = 0.03 among the entire cohort and r = 0.362; p = 0.035 in the non-proliferative-DR group), sBP (r = 0.278; p = 0.038 among the entire cohort), and dBP (r = 0.284; p = 0.034 among the entire cohort and r = 0.482; p = 0.004 in the proliferative-DR group). In the ROC analysis, we found that the NT-proCNP level predicted a high ASCVD risk score with 83.3% sensitivity and 70.8% specificity and a very high ASCVD risk score with 100% sensitivity and 69.2% specificity among the proliferative-DR patients. No cut-off value was calculated for the prediction of high and very-high ASCVD risk scores in patients with non-proliferative DR. Similarly, no cut-off value was revealed for the prediction of established coronary artery disease in all groups. CONCLUSIONS: Our study revealed a significant association between NT-proCNP levels and high ASCVD risk scores in patients with proliferative DR.

Small Bowel Video Capsule Endoscopy Guidance in Practice: Expert Opinion Report.

Capsule endoscopy, in clinical use since the 2000s, has disrupted the diagnosis of various small bowel diseases, especially obscuregastrointestinal bleeding. An overview of information on indications, contraindications, patient management, and patient preparationfor capsule endoscopy, which allows the evaluation of the entire gastrointestinal tract, will be helpful for both referrers and capsuleendoscopy. This review critically considers current evidence on the optimal clinical use of capsule endoscopy and addresses areas in the "gray zone."

Comparison of Hospitalized COVID-19 Patients in Terms of Disease Course According to the Presence of Gastrointestinal Symptoms Before and After Admission.

BACKGROUND: This study aimed to find the prevalence of gastrointestinal symptoms in hospitalized COVID-19 patients and to investigate the effects of gastrointestinal symptoms on the course of the disease during hospitalization. METHODS: Patients who were hospitalized due to COVID-19 were included in this retrospective study. The diagnostic method of COVID-19 was either a positive reverse transcription polymerase chain reaction test or a typical finding in chest computed tomography. This study was conducted by contacting patients by phone 1 month after they were discharged from hospital to investigate gastrointestinal symptoms. Patients' laboratory findings at the time of admission, medications they used, and clinical findings were obtained from hospital records retrospectively. Patients with gastrointestinal symptoms were divided into 2 groups according to the start of treatment: pre-treatment and post-treatment groups. RESULTS: At least 1 gastrointestinal symptom (anorexia, weight loss, diarrhea, nausea, vomiting, and abdominal pain) was present in 67.5% of 435 patients (55.6% male, mean age 52.8). If anorexia and weight loss are excluded, the rate of the presence of at least 1 gastrointestinal symptom is 54%. Gastrointestinal symptoms were present in 48.9% before the initiation of COVID-19 treatment. The most prevalent 3 symptoms were anorexia, weight loss, and diarrhea (56%, 52%, and 35.6%, respectively). Presence of pre-treatment gastrointestinal symptoms was associated with elevated C-reactive protein levels. Pre-treatment gastrointestinal symptoms were more common in those who received oxygen supply and who were intubated. Resolution of gastrointestinal symptoms takes longer time in those who were admitted to intensive care unit. Weight loss and diarrhea were more common in COVID-19 patients with gastrointestinal symptoms who were intubated than who were not intubated. Abdominal pain was not found to be a significant predictor of disease severity. CONCLUSION: The prevalence of at least 1 gastrointestinal symptom in hospitalized COVID-19 patients was 67%. The most prevalent symptoms were anorexia, weight loss, and diarrhea. Presence of pre-treatment gastrointestinal symptoms was associated with elevated C-reactive protein levels, use of oxygen supply, and intubation. Gastrointestinal symptoms persist longer in those admitted to intensive care unit.

The liver-kidney axis: Is serum leptin a potential link in non-alcoholic fatty liver disease-associated chronic kidney disease?

BACKGROUND AND STUDY AIMS: Non-alcoholic fatty liver disease (NAFLD) is an independent risk factor for chronic kidney disease (CKD). Previous studies argued that leptin levels increase significantly with the progression of CKD. But the association between leptin and CKD has not been investigated in patients with NAFLD. Therefore, we conducted this study to establish whether increased leptin level is associated with CKD in NAFLD patients. PATIENTS AND METHODS: In our prospective study with a follow up period of six months thirty-five teetotaller biopsy-proven NAFLD patients were divided as groups with mild, versus advanced, fibrosis. Liver fibrosis was also assessed with Fibroscan. Serum leptin levels were measured by radioimmunoassay. For insulin resistance we used the homeostasis model assessment method (HOMA-IR). For the kidney function, we used the abbreviated formula Modification of Diet in Renal Disease (MDRD) formula, which estimates GFR. For statistical analysis, Student's-t test, Mann-Whitney test, linear regression-binary logistic regression analyses and the ROC curve analysis were used. RESULTS: Advanced fibrosis and increased HOMA-IR were risk factors for decreased eGFR. Leptin correlated inversely with advanced fibrosis (p: 0.03) and low leptin was a risk factor for CKD (p: 0.02). In ROC curve analysis, advanced fibrosis and low leptin were risk factors for decreased eGFR (p: 0.007 and 0.004, respectively). Low leptin level was dependently associated with decreased eGFR. CONCLUSION: Advanced fibrosis in NAFLD patients is a risk factor for CKD. Leptin correlated inversely with advanced fibrosis. Unlike the previous studies, which were not performed in NAFLD patients, we found decreased leptin in NAFLD patients with decreased eGFR. Low leptin level was found to be a dependent predictor for differentiating NAFLD patients with high risk for CKD.

Clinical Contribution of Standardized Terminology for Pancreatic Lesions' Cytopathology.

INTRODUCTION: Demonstration of diagnostic contribution of Papanicolaou Society of Cytopathology-standardized nomenclature for pancreaticobiliary cytology (PSC-PC) in endoscopic ultrasonography (EUS) fine-needle biopsy (FNA) biopsies is important for widespread use and further development. METHODS: 179 EUS-FNA biopsies (89: solid, 90: cystic) and PSC-PC categories were compared with surgical definite histopathology and definite clinical diagnosis. Overall risk of malignancy (oROM) was calculated for each PSC-PC category. Diagnostic accuracy was evaluated. RESULTS: The cytopathology of lesions was nondiagnostic in 27%. Ductal dilatation, lymphadenopathy, and solid characteristic (independently) were associated with diagnostic result, while lesion size was not. PSC-PC categories had 89% diagnostic consistency with surgical definite histopathology. Category mismatch was detected in 3 patients (11%), of which 2 had adenocarcinoma. oROM was 14.3% for nondiagnostic group, 46% for cat. III (atypia), and 12% for cat. IVB (neoplastic - other). In terms of malignancy, the PSC-PC system had 100% specificity; PPV, 92% sensitivity, and 81% NPV; and the diagnostic accuracy was 94%. CONCLUSION: Using PSC-PC in EUS-FNA biopsies, pancreatic malignancy can be diagnosed with high diagnostic accuracy. In mucinous cystic lesions, some malignancies may be missed. To predict the malignancy risk of cat. IVB, assessment of dysplasia seems important. Although PSC-PC is not the only parameter in terms of diagnosing malignancy, its contribution to the clinical decision is quite high.

Renal Manifestations in Inflammatory Bowel Disease: A Cohort Study During the Biologic Era.

BACKGROUND Renal involvement can complicate the course of inflammatory bowel disease (IBD). In this study, we aimed to analyze the extent of renal manifestations in patients with IBD (Crohn disease or ulcerative colitis) during the biologic era. MATERIAL AND METHODS Patients diagnosed with and followed up for IBD for a period covering 16 years were retrospectively analyzed. Patients who received IBD diagnosis with clinical, endoscopic, and histopathological findings and were older than 18 years were enrolled in the study. Demographic, clinical, laboratory, and treatment data were retrieved from the patients' medical records. RESULTS Of the 1874 patients analyzed, the diagnosis was ulcerative colitis in 1055 patients and Crohn disease in the remaining 819. Renal manifestations were found in 105 patients (5.6%), 55 (6.7%) of whom were diagnosed with Crohn disease and 50 (4.7%) with ulcerative colitis. Renal calculi was the most common renal manifestation for both Crohn disease and ulcerative colitis. Renal manifestations were related to disease activity and surgical resection history in patients with Crohn disease, whereas no such relationship was found in patients with ulcerative colitis. CONCLUSIONS Renal manifestations may be seen in up to 6% of patients with IBD, and patients with Crohn disease seems to have more risk than do patients with ulcerative colitis. Nephrolithiasis is the most common form of renal involvement in IBD and is closely associated with disease activity. This relationship between IBD and renal manifestations should be considered, especially when there are subtle renal symptoms.

Malnutrition treatment and follow-up in clinical nutrition outpatient clinics associated with increased muscle mass.

OBJECTIVE: Clinical nutrition outpatient clinics (CNOCs) are the mainstay of the nutrition bundle in hospitals. They are important for the diagnosis, treatment, and follow-up of outpatients with malnutrition (MN) and sarcopenia. The aim of this study was to evaluate changes in muscle mass during the treatment of MN in patients admitted to CNOCs. METHODS: A total number of 1118 patients were included in this retrospective cohort descriptive study. Data including medical history, weight loss, anthropometric measurements, MN diagnosis (according to ESPEN definition), nutrition treatment, bioelectrical impedance analysis and laboratory examinations were noted for the first admission and the follow-up. RESULTS: This retrospective, cohort descriptive study included 1118 patients. The mean age of the participants was 54 ± 22 y (18-101 y) and half of the patients were men. Of the 1118 patients, 37,7% were ≥65 y of age. Cancer (32.2%) was the most frequent diagnosis followed by diabetes (16.7%) and dementia (11.3%). MN prevalence was 51.6%. Protein- and energy-enriched diet, oral enteral nutrition supplementation, tube enteral feeding, and parenteral nutrition were used in 42.7%, 69.6%, 11%, and 2.7% of the patients with MN, respectively. Skeletal muscle mass was significantly increased in MN, cancer, neuromuscular diseases (NMD) and patients ≥65 y of age in the first 6 mo, and could be maintained during the next 6 mo of follow-up. Patients with cancer, chronic kidney disease, and NMD and those ≥65 y of age were able to increase their body mass index. CONCLUSIONS: MN treatment and follow-up can restore muscle mass especially in patients ≥65 y of age and in those with chronic diseases. CNOCs are beneficial in the treatment and follow-up of MN.

The Psychological Effects of COVID-19 Pandemic in Patients with Inflammatory Bowel Disease.

BACKGROUND: Coronavirus disease 2019 pandemic was expected to have traumatic effects and increase the anxiety levels of inflamma- tory bowel disease patients. METHODS: We aimed to investigate the psychosocial effects of the coronavirus disease 2019 pandemic on patients with inflammatory bowel disease by revealing the risk perception for present disease, coping strategies, follow-up characteristics, and treatment adher- ence. This is a cross-sectional, web-based survey study including 798 inflammatory bowel disease patients who were followed at our outpatient clinic and 303 volunteer who did not have any known chronic diseases and were not health professionals were included as the control group. RESULTS: In this study, 281 of the patients were diagnosed with Crohn's disease and 215 with ulcerative colitis. The mean age of patients with Crohn's disease, ulcerative colitis, and the control group were 40.9 ± 13.1, 42.3 ± 12.7, and 39.9 ± 11.6, respectively. Here, 119 (42%) of the Crohn's disease cases, 116 (54%) of the ulcerative colitis cases, and 170 (56%) of the control group were male. Among the 3 groups, coronavirus disease 2019-related post-traumatic stress disorder rates (Impact of Event Scale-Revised > 33) and State-Trait Anxiety Inventory of current status of anxiety-related anxiety rates were not statistically different while State-Trait Anxiety Inventory of anxiety tendency-related constant anxiety was higher in inflammatory bowel disease patients than the control group (P < .017). CONCLUSION: Inflammatory bowel disease patients with anxiety have a lower quality of life, and this may worsen the clinical course of the disease. Coronavirus disease 2019 is a major source of stress for such a vulnerable population. During the pandemic, psychological support and mental health awareness should be made accessible to all individuals.

Can Interferon Therapy Change the Natural Course of Hepatitis Delta Infection?: a Clinical and Pathological Study.

Chronic delta hepatitis (CDH) has a worse outcome than other types of viral hepatitis. High-dose, long-term alpha interferon (IFN-α) is the approved treatment and may ameliorate the course of infection. We evaluated long-term histological outcomes of CDH patients treated with IFN-α. Patients with histologically proved noncirrhotic CDH who were treated with high-dose IFN-α for at least 1 year were classified as cirrhotic or noncirrhotic at the end of treatment. Noncirrhotic patients also had posttreatment liver biopsies. Patients were designated histologically responsive or nonresponsive on the basis of fibrosis status. Histological, virological, and biochemical courses were analyzed. Forty-eight patients were treated with IFN-α (conventional and/or pegylated) for a median of 24 months with a posttreatment follow-up of 5 years. During the follow-up, cirrhosis developed in 24 patients, 5 of whom were decompensated. There was no difference between pre- and posttreatment fibrosis scores for 24 noncirrhotic patients at the end of follow-up. Among patients, 13% (n = 6) had decreased, 21% (n = 10) had steady, and 16% (n = 8) had increased fibrosis scores. Persistent viral response (PVR) was achieved in 16 patients (33%). Twenty percent of the entire group was histologically responsive (decreasing or steady fibrosis scores with improved necroinflammatory scores), while nearly 80% had histological progression/cirrhosis. PVR was significantly associated with histological response. The long-term natural course of patients who were treated with high dose IFN-α for at least 1 year was evaluated clinically and histologically. Despite the association of PVR with histological response, IFN-α treatment did not change the natural course of CDH; clinical and histological progression continued in two-thirds of the cases despite treatment.

Can we predict mucosal remission in ulcerative colitis more precisely with a redefined cutoff level of C-reactive protein?

AIM: Most patients with ulcerative colitis (UC) with active mucosal disease have a lower C-reactive protein (CRP) level than the classic accepted cutoff level (≤5 mg/l). We aimed to predict the mucosal remission in UC with an optimal cutoff level of CRP when mucosal activity and extensiveness of UC were both considered. METHOD: In this retrospective study, we evaluated CRP values and their relation to mucosal extension and UC activity in 331 colonoscopic examinations performed between December 2016 and March 2019. Endoscopic activity and disease extension were assessed using Mayo scores and the Montreal classification. RESULTS: The Mayo 2 and 3 groups' CRP values were significantly higher when compared with Mayo 0-1 between values of E1 and both E2 and E3 with an increasing trend. The standard CRP cutoff level ≤5 mg/l only yielded 55% specificity in predicting mucosal remission. In the ROC analysis, a CRP cutoff level ≤2.9 mg/l predicted an overall mucosal remission (Mayo 0-1) with 77% sensitivity and 80% specificity, and ≤1.9 mg/l predicted Mayo-0 with 70% sensitivity and specificity. In the clinical remission subgroup, the overall CRP cutoff level was even lower, at ≤1.58 mg/l. CONCLUSION: An overall CRP cutoff level ≤2.9 mg/l predicts mucosal remission in UC better than the standard cutoff ≤5 mg/l. Mucosal remission in stable clinical remission may present with an even lower CRP level. An increasing trend in the CRP level from E1 through E3 even in mucosal remission suggests that both histological inflammation and extensiveness may have some influence on a CRP-based prediction of endoscopic remission.

Subclinic arterial and left ventricular systolic impairment in autosomal dominant polycystic kidney disease with preserved renal functions.

Subclinical atherosclerosis and cardiovascular events are common even in young normotensive patients with autosomal dominant polycystic kidney disease (ADPKD). Our aim was to examine the relationship between serum fibroblast growth factor-23 (FGF-23) levels, left ventricular global longitudinal strain (LV-GLS), arterial stiffness (AS), and carotid intima-media thickness (CIMT) in patients with ADPKD with preserved kidney function. The relationship between albuminuria, AS, LV-GLS, CIMT, 24-hour ambulatory blood pressure measurement, and FGF-23 was examined in 52 normotensive and hypertensive patients with ADPKD and a matched control group of 35 subjects. AS was assesed with brachial-ankle pulse wave velocity, LV-GLS was measured with speckle-tracking echocardiography. FGF-23 was measured with enzyme-linked immunosorbent assay. The microalbumin/creatinine ratio was significantly higher in the ADPKD group than in the control group (p?

Acquired FVIII and FIX Inhibitors after Pregnancy: A Case Report.

Acquired hemophilia is a relatively rare clinical presentation, and most cases present with acquired FVIII inhibitor. The co-occurrence of inhibitors to multiple coagulation factors is uncommon. These autoantibodies may induce spontaneous life-threatening bleeding in patients who have had no previous bleeding disorder. Herein, we present a patient with postpartum acquired FVIII and FIX inhibitors who developed intramuscular hematoma and hemothorax during follow-up. She was then treated with activated prothrombin complex concentrate and methylprednisolone.

Case report of fatal Mycobacterium tilburgii infection.

There are few reports concerning Mycobacterium tilburgii infection in humans because this bacterium is non-cultivatable. Herein, using new molecular techniques, we report the case of an immunocompromised patient with fatal disseminated lymphadenitis that was caused by M. tilburgii.26 years old Caucasian HIV negative female patient presented with abdominal pain. Her clinical assessment revealed disseminated lymphadenitis, that was acid fast bacilli positive. Further molecular evaluation showed the causative agent as M. tilburgii. Despite anti mycobacterial therapy and careful management of intervening complications patient died because of an intraabdominal sepsis. This is the first fatal M. tilburgii infection in the literature. This case points the importance of careful management of patient's immune status and intervening infections besides implementation of effective drug treatment.
