The Relationship between Mean Platelet Volume and Neutrophil-Lymphocyte Ratio and Liver Fibrosis in Patients with Chronic Hepatitis B.

Objective: The neutrophil-lymphocyte ratio (NLR) can be helpful both in demonstrating acute and chronic liver injury and predicting malignant potential. The mean platelet volume (MPV) is also a marker that can be used as a risk indicator in atherosclerosis-associated diseases, reflecting inflammation. Within the scope of this research, we aimed to elucidate the relationship between the mean platelet volume and neutrophil-lymphocyte ratio in liver fibrosis in chronic hepatitis B patients. Materials and Methods: A total of 84 patients who were followed up with the diagnosis of chronic hepatitis B and who underwent liver biopsy were included in this prospective study. Complete blood count parameters (neutrophil, lymphocyte, neutrophil-lymphocyte ratio, hemoglobin, thrombocyte, MCV, and MPV values), demographic data, biochemistry panel (AST, ALT), HBV DNA, and liver biopsy fibrosis scores obtained from hospital database were analyzed. Since the follow-up period of chronic hepatitis B patients is six months, patients were screened in order to include a full 3-year screening pool. Results: A total of 84 patients were enrolled within the scope of this study. The chronicity index was '0' in 7.1% (n = 6), '1' in 23.8% (n = 20), '2' in 56% (n = 47), and '3' in 13.1% (n = 11)of the patients. According to the chronicity index groups, there was a statistically significant difference between the medians of the hepatitis activity index (HAI) values at the 5% significance level (p < 0.001). The correlation analysis revealed a statistically significant relationship between the chronicity index and the mean platelet volume to lymphocyte ratio (MPVL). However, considering the degree of the relationship, it can be said that it was a positive and weak relationship (p = 0.046, r = 0.218). Conclusions: Regarding the outcomes of this research, a significant relationship was found between the neutrophil-lymphocyte ratio, mean platelet volume, and fibrosis.

Assessment of the underlying causes of the immune thrombocytopenia: Ten years experience.

OBJECTIVE: Immune thrombocytopenia (ITP) is an immune haematologic disorder causing platelet destruction mediated by anti-platelet antibodies. In this study we aimed to evaluate the clinical and laboratory variables of ITP patients in southeast of Turkey. METHODS: In this retrospective study 167 ITP patients between 2005 and 2015 were evaluated. All patients were screened for immunological parameters including ANA (antinuclear antibodies), anti dsDNA (anti-double-stranded-DNA), ACA(anti-cardiolipin) IgM and IgG, LA (lupus anticoagulants). All patients were screened for Helicobacter pylori, HBsAg (Hepatitis B surface antigen), anti-HCV (hepatitis C virus antibody), and anti-HIV ½ (HIV antibody) and brucellosis.. RESULTS: Among the patients, 50 (29.9%) patients were male, 117 (70.1%) were female. The age range of patients was 18-86 (mean 38.16±14). In 56 patients (33.5%) splenectomy was performed. 36 patients (21.6%) were positive for ANA, 5 (3%) were positive for anti dsDNA, 14 (8.4%) for ACA Ig G, and 14 (8.4%) patients for ACA IgM. LA was tested in 165 patients and 30 (18%) patients were positive for LA. Microbiologic evaluation was as follows: 16 patients (9.6%) were positive for HbsAg, 109 (65.3%) positive for Anti-HBs, 5 positive for anti-HCV (3%), 56 (33.5%) patients were positive for Helicobacter pylori antigen, 5 (2.9%) for Brucella and one patient was positive for anti-HIV ½. CONCLUSIONS: Immune thrombocytopenia patients have to be evaluated according to their demographic characteristics and laboratory results. Secondary causes of ITP were HIV, HCV, Helicobacter pylori, brucellosis, tuberculosis, and autoimmune diseases in our region. Management of ITP patients can change in different regions.

Evaluation of patients via colonoscopy who underwent positron emission tomography/computerized tomography due to colon involvement.

OBJECTIVE: Fluorodeoxyglucose is not a tumor-specific agent and it can also be involved in benign conditions, which may cause diagnostic confusion. This research aims to elucidate the colonoscopic findings of patients who underwent colonoscopy due to colon involvement in positron emission tomography/computerized tomography. METHODS: A total of 71 patients who underwent colonoscopy due to colonic involvement in positron emission tomography/computerized tomography at SBU Keçiören Training and Research Hospital Gastroenterology Clinic Endoscopy Unit have been analyzed retrospectively. Demographic characteristics of the patients, areas of involvement in positron emission tomography/computerized tomography, and severity have been obtained from the hospital database. RESULTS: The gastrointestinal involvement area of 22.5% (n=16) of the patients was ascending colon, 15.5% (n=11) was sigmoid, 15.5% (n=11) was rectum, 12.7% (n=9) was stomach, 11.3% (n=8) was transverse colon, 8.5% (n=6) was anal canal, 5.6% (n=4) was esophagus, and 5.6% (n=4) was descending colon. The endoscopic findings of 19.7% (n=14) patients were normal, whereas 29.6% (n=21) had polyps, 9.9% (n=7) had cancer, 2.8% (n=2) had an ulcer, 15.5% (n=11) had gastritis, 14.1% (n=10) had hemorrhoids, and 7% (n=5) had colitis. CONCLUSION: Fluorodeoxyglucose-positron emission tomography can detect unexpected distant metastases with high sensitivity because it allows whole-body imaging. Curative resection significantly contributes to the choice of treatment modality in the pre-operative period of colorectal cancer patients with planned surgery.

Presentation and Management of Paroxysmal Nocturnal Hemoglobinuria: A Single-Center Experience.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired disorder characterized by intravascular hemolysis. Real-world experience of PNH management is largely unreported. A retrospective analysis was undertaken based on medical records from six patients with PNH [two with aplastic anemia (AA)] treated at our center, Dicle University, Turkey. Diagnosis was based on granulocyte PNH clones, ranging from 93% to 66%. All patients had symptoms consistent with PNH. One patient was managed adequately with supportive measures only. Five were treated with the complement inhibitor eculizumab. Follow-up data (<1 year) were available in four cases (the fifth had received only three infusions by final follow-up). Hemoglobin level in these four patients increased from 4.1-7.2 g/dL to 8.3-13.0 g/dL. Lactate dehydrogenase, a marker for hemolysis, decreased profoundly in the two non-AA patients, with more minor improvements in the two AA patients. Weakness and fatigue improved in all eculizumab-treated patients. Four of the five treated patients became transfusion independent, including the patient given only three infusions. In the remaining case, a patient with AA, transfusion requirement decreased, and abdominal pain and dysphagia resolved. No adverse events occurred. PNH can be successfully managed in routine practice.
