Omental calcified fibrous tumor with symptoms after COVID-19 infection.

Calcified fibrous tumor (CFT) is a rare benign tumor of mesenchymal origin. Between 1988 and 2019, a total of 272 CFT cases were reported. CFTs can be seen in all anatomical regions with soft tissue. Histologically, mononuclear inflammatory infiltrates and the presence of psammomatous calcification in dense hyalinized collagen are characteristic features of the tumor. Currently, if the tumor is located in only one focus, surgical removal is recommended. Although CFT is a benign tumor, it may cause complications. Diagnosis is often difficult due to the confusion of tumor findings with many diseases. We present a patient with CFT, whose omental lesions were detected on abdominal computed tomography, and the diagnosis was confirmed by histopathological examination.

Assessment of venous leg symptoms in patients with hemorrhoidal disease (VEIN-HEMORRHOID study).

BACKGROUND: Coexistence of dilating venous diseases in different vascular territories has raised the idea that they have similar vascular wall abnormality in their evolutionary process. Accordingly, we aimed to evaluate venous leg symptoms in patients with hemorrhoidal disease (HD) by means of VEINES-Sym questionnaire. MATERIALS AND METHODS: The study involved 249 consecutive patients who underwent colonoscopy and met the inclusion criteria. Presence and grading of HD were made according to Goligher's classification. All patients were examined for the existing of varicose vein and classified in respect of CEAP classification. All participants were requested to answer the VEINES-Sym questionnaire. RESULTS: There was not statistically significant differences between the patients without HD (grade 0 or I) and with HD (Grade II or III) in respect to clinical characteristics except female predominance in hemorrhoid group (p = 0.07). Scores of heavy legs, swelling, burning sensation, restless leg, throbbing, tingling, and total VEINES score were significantly lower (ie: worse) in hemorrhoid group. Logistic regression analysis revealed that female gender and total VEINES score were independently associated with HD (OR: 2.03, 95% CI: 1.17-3.52, p = 0.01; OR: 0.96, 95% CI: 0.92-0.99, p = 0.02, respectively). Among all venous leg symptoms, severity of heavy legs, night cramps, swelling and aching were significantly correlated with the grades of HD. CONCLUSION: We have shown significant association between the HD and venous leg symptoms reflected by total VEINES score and significant correlation between the HD grade and venous leg symptoms severity including heavy legs, swelling, night cramps and aching legs.

NS5A resistance - associated substitutions in chronic hepatitis C patients with direct acting antiviral treatment failure in Turkey.

OBJECTIVES: Chronic hepatitis C (CHC) is now a more curable disease with new direct acting antivirals (DAA). Although high sustained virologic response rates, failures still occur in DAA regimens. Our objective in this study was to characterize the real-life presence of clinically relevant resistance - associated substitutions (RASs) in the HCV NS5A gene in CHC patients whose DAA regimen has failed. METHODS: The study enrolled 53 CHC patients who experienced failure with DAA regimen as the prospective longitudinal cohort between 2017-2019. Genotypic resistance testing was performed via the viral population sequencing method and The Geno2pheno HCV tool was used for RAS analysis. RESULTS: The most frequent failure category was relapse (88%) followed by non-responder (12%). For a total of 36% of patients, RASs was detected in NS5A, Y93H was the most detected RAS in GT1b infected patients (89%). CONCLUSIONS: This study establishes an HCV failure registry for Turkey in which samples were combined with clinical, virologic and molecular data of adult patients whose DAA therapy failed. RASs can occur in CHC patients with DAA treatment failures. Evaluation of RAS after DAA failure is very important before re-treatment is initiated to prevent virologic failure.

High-resolution computed tomography and rheumatoid arthritis: semi-quantitative evaluation of lung damage and its correlation with clinical and functional abnormalities.

BACKGROUND: We aimed to establish risk factors for radiological lung damage associated with rheumatoid arthritis (RA) and determine whether clinical findings and pulmonary function test were correlated with Warrick score calculated on the basis of high-resolution computed tomography or not. METHODS: One hundred thirty RA patients who were followed at rheumatology outpatient clinic were included through retrospective screening. To evaluate radiological involvement, the semi-quantitative evaluation proposed by Warrick was used to assign a score for each lesion based on the severity and extent of the pulmonary damage. In addition to the total score, indices for alveolitis and fibrosis were created. The correlations between each score and clinical and functional parameters were tested for all patients. RESULTS: We showed that age was an independent explanatory variable of radiological lung damage. Percentage of predicted lung diffusion capacity for carbon monoxide (DLco) below 75 % and presence of respiratory symptoms were found to contribute more to radiological lung damage. Warrick score was positively correlated with age at study onset (r = 0.43, p < 0.001). In addition, a negative correlation was found between Warrick score and DLco % predicted (r = -0.357, p = 0.001). Alveolitis index was negatively correlated with DLco % predicted (r = -0.321, p = 0.003). CONCLUSIONS: It is considered that this semi-quantitative method may have added value in early diagnosis, appropriate treatment decisions and follow-up when taken into account together with risk factors associated with pulmonary damage in RA.

Significance of Colonoscopic Findings in Patients After Kidney Graft.

OBJECTIVES: We aimed to investigate the colonoscopy findings in patients after kidney transplant. MATERIALS AND METHODS: We retrospectively analyzed kidney transplant patients who had colonoscopy examinations for various indications between 2011 and 2015. RESULTS: Eighty-one patients (25 women and 56 men) with a mean age of 39 years (range, 18-64 y) were identified. Mean follow-up after transplant was 9 years (range, 1-29 y). The most common indications for colonoscopy were diarrhea (41%), anemia (29%), gastrointestinal bleeding (12%), abdominal pain (12%), and unexplained weight loss (6%). Either colitis or ileitis or both were diagnosed in 20 patients (25%), whereas polyps were found in 9 patients (11%). One patient presented with hematochezia, which was diagnosed as cytomegalovirus colitis. The remaining cases of colitis or ileitis were diagnosed as nonspecific inflammation. Indications for colonoscopy were not correlated with age, duration after transplant, or use of immunosuppressive drugs. A subgroup analysis for mycophenolate-induced colitis found that 88% of patients used mycophenolate, but presence of colitis or ileitis had no statistical correlation with its use. In patients with poor gastrointestinal symptoms, the only significant predictor of presence of colitis or ileitis was a high C-reactive protein value (> 5 mg/dL; P = .02). CONCLUSIONS: Incidence of colitis and/or ileitis is a relatively common finding in patients after kidney transplant. Opportunistic infections, mycophenolate use, and mild degree of indeterminate colitis or ileitis disease may be the underlying condition. Cytomegalovirus infection should be screened in all recipients because it may cause serious complications or death in chronically immunocompromised patients.

Endoscopic Retrograde Cholangiopancreatography in Kidney Transplant Patients: Results From a Single Center.

OBJECTIVES: We report the outcomes of endoscopic retrograde cholangiopancreatography procedures performed for diagnostic and therapeutic purposes in patients who had undergone kidney transplant. MATERIALS AND METHODS: We retrospectively evaluated the records of kidney transplant patients for January 1993 to December 2014. Endoscopic retrograde cholangiopancreatography was carried out using an Olympus JF240 duodenoscope (tip outer diameter 12.6 mm, working channel diameter 3.2 mm). The procedures were performed by Department of Anesthesiology staff while the patients were deeply sedated, given a combination of midazolam plus propofol. RESULTS: Data from 21 kidney transplant patients (16 men and 5 women; mean age at endoscopic retrograde cholangiopancreatography 42.6 ± 23.4 y) were evaluated. A total of 23 endoscopic retrograde cholangiopancreatography procedures were performed. The indications were choledocholithiasis in 6 patients (28.6%), common bile duct dilatation plus liver enzyme elevations in 4 patients (19%), liver enzyme elevation alone in 4 (19%), biliary necrotizing pancreatitis in 2 (9.6%), and cholangitis in 5 (23.8%). Hepatobiliary ultrasonography findings showed that 3 patients (14.3%) had absence of gallbladder owing to cholecystectomy, 14 (66.7%) had gallstones, 1 (4.7%) had gallstones with cholecystitis findings, and 3 (14.3%) were normal. Endoscopic retrograde cholangiopancreatography findings were normal in 4 patients (19%), showed cholangitis in 2 (9.6%), choledocholithiasis in 10 (47.6%), bile duct wall irregularities in 2 (9.6%), dilated common bile duct in 2 (9.6%), and cholangiocarcinoma in 1 (4.7%). Sphincterotomy was performed in 16 patients. None of the patients who underwent endoscopic retrograde cholangiopancreatography developed any complications, for example, acute pancreatitis, bleeding, duodenal, or bile duct perforation. CONCLUSIONS: In kidney transplant patients, endoscopic retrograde cholangiopancreatography is safe and able to provide substantial information for managing biliopancreatic diseases.

Late-Onset Drug-Induced Cholestasis in a Living-Related Liver Transplant Donor With Progressive Familial Intrahepatic Cholestasis.

We present a rare case of progressive familial intrahepatic cholestasis within a family. A 34-yearold female became a living-related liver transplant donor for her son, who had the disease. Nine years after the transplant, the mother developed severe intrahepatic cholestasis, for which she was evaluated after using an oral contraceptive drug. She presented with jaundice, pruritus, and increased bilirubin levels, together with elevated gamma glutamyl transferase and alkaline phosphatase levels. A liver biopsy revealed findings consistent with intrahepatic cholestasis. However, despite follow-up management and cessation of the insulting drug, her total bilirubin count continuously increased to 20 mg/dL and was accompanied by intractable pruritus. A total of 9 plasmapheresis sessions were performed, and she was started on a regimen of ursodeoxycholic acid (13 mg/kg/d) and cholestyramine (4 g, 3 times daily). The clinical and laboratory picture dramatically improved following cessation of the oral contraceptive, plasmapheresis sessions, and drug treatment. The patient's cholestasis normalized within 3 months, and she recovered uneventfully. A genetic analysis of the whole family revealed that both parents were heterozygous for the mutation c.124G>A in ABCB11, and the son was homozygous for this mutation. These findings supported varying degrees of bile salt export pump deficiency in the family members. Defective bile salt excretory system function can result in a wide spectrum of clinical presentations, ranging from progressive familial intrahepatic cholestasis requiring liver transplant to late-onset drug-induced cholestasis. Our findings suggest that, in a heterozygous carrier of a progressive familial intrahepatic cholestasis mutation, drug-induced cholestasis is responsive to treatment, after which the clinical picture can normalize within 3 months.

Factors Affecting Mortality and Morbidity of Patients With Cirrhosis Hospitalized for Spontaneous Bacterial Peritonitis.

OBJECTIVES: Spontaneous bacterial peritonitis, unless originating from surgery or an intra-abdominal source, is an infection diagnosed by neutrophil counts greater than 250/mm³ in ascites. Spontaneous bacterial peritonitis is the most common infection among patients hospitalized with cirrhosis, with a prevalence of 9% and a risk of development among all patients with cirrhosis within 1 year of 10%. No valid parameters have been defined to predict the mortality related to spontaneous bacterial peritonitis. Unless it is treated, the mortality rate as a result of spontaneous bacterial peritonitis is 50%, and serious complications may arise. MATERIALS AND METHODS: Medical records from 29 patients on the deceased-donor transplant waiting list and receiving treatment at the Baskent University Hospital Gastroenterology Clinic for cirrhotic ascites infection between 1996 and 2013 were analyzed. Demographic information, paracentesis findings, clinical follow-up, and treatment results were reviewed and collected from patient medical records, with data recorded to the research form. RESULTS: In our patient group, 72.4% were men and the average age was 46.6 years. Most of our patients were at advanced stage, with 55.2% having a Child-Pugh score of C and an average Model for End-Stage Liver Disease score of 17 ± 4.1. We found that 34.5% of the patients received prophylactic treatment for spontaneous bacterial peritonitis, 72.4% received a proton pump inhibitor, and 82.8% had treatment with intravenous albumin support at the time of diagnosis. Albumin treatment showed no effect on mortality. Mortality rate among patients with Child-Pugh score of C was 81.3%. CONCLUSIONS: Existence of chronic renal failure, liver graft surgery, and hepatocellular cancer did not seem to have a significant effect on patient mortality. The albumin treatment protocol showed no significant difference despite common belief among physicians.

Hepatitis B- and hepatitis D-virus-related liver transplant: single-center data.

OBJECTIVES: Hepatitis B and D virus coinfection or superinfection lead to chronic liver disease and have poor treatment results and poor prognosis. After transplant, these patients have difficult problems. We aimed to report long-term data of liver transplant recipients who had hepatitis B and D virus-related chronic liver disease. MATERIALS AND METHODS: This retrospective, longitudinal study included 25 consecutive hepatitis B surface antigen-positive patients with antihepatitis D virus antibodies. Patient data (age, sex, antiviral treatment, posttransplant use of hepatitis B hyperimmunoglobulin and/or nucleoside/nucleotide analogues, the presence of hepatocellular carcinoma, age at transplant, follow-up) were extracted from patient records. RESULTS: Females comprised 32% patients. The median age was 44 years (range, 23-63 y). The serum Hepatitis B envelope antigen level was negative in all patients. At the time of transplant, 4 patients were positive for hepatitis B virus DNA and 11 patients also had hepatocellular carcinoma. Posttransplant follow-up was 59 months (range, 3-120 mo). During follow-up, 4 patients died, 4 patients were lost to follow-up, and 17 patients were alive. Posttransplant survival of patients with hepatocellular carcinoma was 50.45 months (range, 3-84 mo) and without hepatocellular carcinoma was 65.8 months (range, 4-120 mo). There were 3 patients who had acute rejection and were treated successfully with pulse doses of prednisolone. Hyperimmunoglobulin therapy was used in conjunction with oral nucleotide/nucleoside analogues for 12 months (range, 3-24 mo) and then stopped. After transplant, 4 patients had antiviral medicine changed to adefovir or entecavir because of drug resistance, and otherwise all patients remained negative for hepatitis B virus DNA during follow-up. CONCLUSIONS: Patients transplanted for hepatitis B and D virus cirrhosis, even with hepatocellular carcinoma, had favorable prognosis and good longterm results. Close follow-up of patients and effective viral suppression with suitable drugs were key factors for efficient patient care.

The effect of pretransplant chronic hepatitis C virus infection treatment on graft and patient survival in renal transplant recipients.

OBJECTIVES: Studies have demonstrated worse graft and patient survival among hepatitis C virus-positive patients following kidney transplant. Eradication of hepatitis C virus infection before renal transplant with interferon should be considered in hepatitis C virus-infected patients undergoing dialysis who are on the waiting list for transplant. We investigated whether pretransplant hepatitis C virus infection treatment affected graft and patient survival, and we evaluated other contributing factors to these outcomes. MATERIALS AND METHODS: We enrolled 83 antihepatitis C virus-positive patients who were diagnosed with chronic hepatitis C virus infection by serology or histopathology and had renal transplant at Baskent University Ankara Hospital from 1982 to 2013. Data were obtained from patient medical files retrospectively. Patients were divided into 2 groups that had or did not have interferon treatment. RESULTS: In 83 renal transplant patients with chronic hepatitis C virus infection (57 male [69%] and 26 female [31%]), median age was 46 years (range, 26 - 69 y), and most patients were genotype 1-dominant (92%). Interferon monotherapy was received by 30 patients before renal transplant and 28 of 30 patients had long-term follow-up data. There were 14 of 28 patients (50%) who achieved sustained virologic response, and only 1 patient had relapse. Graft survival was significantly lower in patients who had treatment (6 y vs 9 y; P ≤ .003). However, patient survival rates were similar between groups. Patients who had interferon were younger and had longer hemodialysis duration before renal transplant than patients without treatment. Higher viral load was associated with higher mortality which was caused by sepsis. CONCLUSIONS: Patients with posttransplant lymphoproliferative disorder have high incidence of bone marrow involvement and high mortality rates. Therefore, bone marrow examination may be important in the diagnosis and staging evaluation of posttransplant lymphoproliferative disorder.

Panel reactive antibodies in predicting hepatitis C virus treatment outcome in kidney transplant candidates.

OBJECTIVES: Chronic hepatitis C virus infection compromises hemodialysis patients and increases liver-related mortality. Interferon treatment is associated with improved sustained virological response rates and increased risk of graft loss after kidney transplant. This may be related to the development of antihuman leukocyte antigen antibodies, which may be a surrogate marker of potent immune response. We evaluated panel reactive antibody 1 and 2 levels for prediction of sustained viral response in patients with kidney transplant. MATERIALS AND METHODS: In this retrospective cohort study, we reviewed data from hepatitis C virusinfected hemodialysis patients who received interferon treatment before kidney transplant. Panel reactive antibody > 20% was considered positive. Sustained viral response rates for interferon treatment were obtained and compared with panel reactive antibody 1 and 2 values. RESULTS: There were 40 patients (16 female and 24 male patients; mean age, 41.5 y; range, 18-65 y). Sustained viral response rate was 18/40 (45%). Panel reactive antibody 1 was negative in 31 patients and positive in 9 patients. Sustained viral response ratio was not correlated with panel reactive antibody 1 positivity. Panel reactive antibody 2 was negative in 31 patients (sustained viral response: present, 11 patients; absent, 20 patients) and positive in 9 patients (sustained viral response: present, 7 patients; absent, 2 patients). Sustained viral response ratio was significantly correlated with panel reactive antibody 2 positivity. CONCLUSIONS: We showed a correlation between panel reactive antibody 2 positivity and sustained viral response rates that may be a predictive tool for hepatitis C virus treatment response. In patients with other complications that compromise hepatitis C virus treatment, panel reactive antibody 2 may be a surrogate marker for sustained viral response prediction. The induction of cellular immunity may cause clearance of hepatitis C virus infection and formation of high panel reactive antibody 2 levels.

Evaluation of the efficacy of aprepitant on the prevention of chemotherapy-induced nausea and vomiting and quality of life with functional living index emesis.

OBJECTIVE: Functional Living Index Emesis (FLIE) is developed to evaluate the relationship between emesis and it's effects on patient's daily life and is far more relevant to detect the effectiveness of antiemetic treatment compared with self-diary reports. In this study, the efficacy of oral neurokinin-1 antagonist aprepitant on the prevention of chemotherapy-induced nausea and vomiting and quality of life is evaluated with FLIE. STUDY DESIGN: Cross sectional study. MATERIAL AND METHODS: Sixty patients with Non-Small Cell Lung Cancer (NSCLC) receiving a chemotherapy regimen consisting of Cisplatin and Docetaxel were evaluated. The patients were prospectively randomized to two groups before the first cycle of chemotherapy. Patients in Group A (31 patients) received 3 daily doses of aprepitant along with oral ondansetron and dexamethasone. The patients in group B (29 patients) received only ondansetron and dexamathasone. The efficacy of both regimens was evaluated by a modified Turkish version of FLIE scale consisting of 18 questions. RESULTS: The number of patients with complete response was 31 in the whole group. Of these 18 patients (58%) were in Group A (Aprepitant) and 13 patients in group B (42%). Median FLIE score in group A was 24.97 (±12.45) while it was 38.1 (±26.987) in group B and the difference was statistically significant (p=0.022). Total score >20 was seen in only 5 of 31 patients in aprepitant group (16%) showing the significant efficiency of aprepitant on quality of life, while in group B, 13 of 29 patients (44%) had total scores >20 (p=0.02). CONCLUSION: Regarding these findings, it is certain to state that aprepitant in combination with other drugs optimizes protection against both nausea and vomiting compared to the prior standard of care, and must be recommended as first-line therapy for patients who are treated with moderately or highly emetogenic chemotherapy.

Severe jaundice due to coexistence of Dubin-Johnson syndrome and hereditary spherocytosis: a case report.

Dubin-Johnson syndrome is a chronic, benign, intermittent jaundice, mostly of conjugated hyperbilirubinemia. The level of bilirubin is not expected to be more than 20 mg/dl in this syndrome. In this article, we report a patient who was evaluated for hyperbilirubinemia and liver function test abnormalities and diagnosed with Dubin-Johnson syndrome coexisting with hereditary spherocytosis. We suggest that other diseases should be investigated if patients with Dubin-Johnson syndrome present with severe hyperbilirubinemia. Dubin-Johnson syndrome accompanied by hemolytic diseases might also have high coproporphyrin levels (as in Rotor's syndrome) than expected in pure Dubin-Johnson syndrome.
