ABSTRACT

BACKGROUND: Cutaneous side effects are commonly seen in cancer chemotherapy. As new chemotherapy drugs are developed, the frequency and the diversity of these cutaneous side effects increase. For this reason, identification and management of these side effects are an important part of the treatment of cancer patients. This study aimed to investigate mucocutaneous side effects of conventional chemotherapy and targeted therapy agents that are used in cancer patients. METHODS: In this cross-sectional study, 231 cancer patients, who received single or combination chemotherapy at the oncology department of our hospital between 2013 and 2020, were retrospectively reviewed, and mucocutaneous side effects we evaluated. RESULTS: The ages of the patients varied between 27 and 90 years with a median age of 60 years. Of the patients, 136 (58.9%) were women, and 95 (41.1%) were men. Combination chemotherapy was applied to 174 patients (71.9%). A total of 558 mucocutaneous side effects were present in 231 patients. The most common side effect was alopecia, which was observed in 158 patients (65.6%). This was followed by mucositis (39.4%), hand-foot syndrome (35.3%), papulopustular rash (22%), dermatitis (18.3%), xerosis (14.1%), nail disorders (12%), and others. CONCLUSIONS: Although chemotherapy-induced cutaneous side effects are not usually life-threatening, they may lead to the development of morbidity and discontinuance or termination of the treatment. Therefore, these side effects should be well managed to improve the quality of life of cancer patients.

ABSTRACT

BACKGROUND/AIMS: Acute graft-versus-host disease (GVHD) is a common complication of haematopoietic cell transplantation (HCT), with the gastrointestinal tract (GIT) as one of the main target organs. There is a lack of consensus regarding the site in GIT with the highest sensitivity for biopsy. The present study aimed to determine the endoscopic and histological findings in acute GVHD. MATERIALS AND METHODS: The data of 111 patients who had received allogeneic HCT were retrospectively reviewed. RESULTS: Allogeneic HCT was performed in 111 patients, of whom 27 (24.3%) had developed acute GVHD. Nineteen of the 111 patients with intestinal symptoms were evaluated for intestinal involvement, and 17 were diagnosed with acute intestinal GVHD. Upper endoscopic findings had a sensitivity of 64.7%, a specificity of 50%, a positive predictive value of 91.6% and a negative predictive value of 14.2%. The diagnostic accuracy of upper endoscopy was 63.1%. Lower endoscopic findings had a sensitivity of 40% and a specificity of 0%. The diagnostic accuracy of upper endoscopy with duodenal biopsy and sigmoidoscopy was 94.1%. CONCLUSION: Endoscopic findings are nonspecific in acute intestinal GVHD. There is little agreement between endoscopic findings and histopathology; thus, biopsies are essential. In patients with intestinal symptoms after HCT, upper endoscopy with duodenal biopsy and sigmoidoscopy has an acceptable diagnostic yield for intestinal involvement.

ABSTRACT

Cancer, chemotherapy, and infections all together make changes in blood rheology and may affect the defense mechanisms by changing the thrombocyte function and endothelial cell. We have examined changes of blood rheology on plasma viscosity to put on probable following criteria for starting the treatment of febrile neutropenia immediately. A total of 27 postchemotherapy patients (16 males and 11 females) with febrile neutropenia diagnosed according to international guidelines have been included into the study. The plasma viscosity of the patients whose febrile neutropenia has been successfully treated was also measured to assess the impact of the duration of neutropenia on viscosity. The plasma viscosities of the patients were significantly higher during neutropenic episode than in nonneutropenic state (P = 0.006) except for alkaline phosphatase. All study parameters, particularly acute phase reactants, were statistically similar during both states. In the correlation of analysis with study parameters and stages, significant correlation was not observed between plasma viscosity alteration and leukocyte-neutrophil alteration, also other study parameters. We have demonstrated significantly elevated plasma viscosity in our patients during febrile neutropenic episode. Despite normal values of various parameters known to trigger plasma viscosity, particularly fibrinogen, it can be easily argued that the main mechanism may be the endothelial injury during infectious process and immune response mediated microcirculatory blood flow alterations.

ABSTRACT

In this study, the importance of plasma viscosity (PV) as a biomarker in differential diagnosis of dementia subtypes especially Alzheimer's disease (AD) and vascular dementia (VaD) was investigated. Our study recruited 45 patients with AD, 35 patients with VaD, and control participants. Individuals with inflammatory disease, infection, heart, liver, renal failure, and with high erythrocyte sedimentation rate and C-reactive protein levels were excluded from the study. The cases underwent comprehensive geriatric assessment. The PV measurements were performed with Brookfield DV-II viscometer. The PV measurements of AD, VaD, and control groups were 1.61 ± 0.08, 1.70 ± 0.06, and 1.48 ± 0.06 mPa S, respectively. The PV levels of the dementia group were significantly higher than the control group (P < .001). When the dementia group was analyzed by itself, patients with VaD had higher PV levels than the patients with AD (P < .001). The PV is a biomarker to be used in diagnosis as well as in differentiating between the 2 most common forms of dementia which are AD and VaD.

ABSTRACT

OBJECTIVE: This study investigated whether or not the stress and hypoxia, which are the effects of radiation on normal vascular endothelium, leading to the release of HIF-1α, VEGF, eIF2, TIA-1, and TSP-1 were related and the possibility of them stimulating angiogenesis. MATERIALS AND METHODS: Twenty-four male Swiss Albino mice were separated into 4 groups. The first group was the control group (Group 1), and the second, third, and fourth groups were euthanized after 24 h (Group 2), 48 h (Group 3), and 7 days (Group 4), respectively. A single-fractioned 10 Gy of ionizing radiation was applied to all mice's pelvic zone with Co-60. Bladders were removed completely from the pelvic region. Immunohistochemistry and light microscopy were used to investigate whether there would be an increase or not in the angiogenesis pathway by using the HIF-1α, VEGF, eIF2, TIA-1, and TSP-1 antibodies. RESULTS: The HIF-1α antibody showed strong staining in Group 3, while the staining intensity was less in other groups. VEGF showed weak staining in Groups 1 and 4, while moderate staining in Group 2 and strong staining in Group 3 was observed. eIF2 showed strong staining in Groups 1 and 4. Groups 2 and 3 were stained weakly. In the present study, staining with TSP-1 was very strong in the samples belonging to Group 1, while other groups showed very weak staining. CONCLUSION: When normal tissue was exposed to radiation, the positively effective factors (HIF-1, VEGF, eIF2, and TIA-1) on the angiogenesis pathway were increased while the negative factor (TSP-1) was decreased. Radiation may initiate physiological angiogenesis in the normal tissue and accelerate healing in the damaged normal tissue. CONFLICT OF INTEREST: None declared.

ABSTRACT

OBJECTIVE: The accompanying thrombocytosis is referred to as the major factor associated with thromboembolism in iron deficiency anemia (IDA). Increased viscosity may increase the risk of thrombosis. We hypothesized that increased platelet count -with reactive thrombocytosis- might also affect plasma viscosity. We planned to evaluate the influence of normal and high platelet count on plasma viscosity in IDA patients. MATERIAL AND METHODS: The patient population consisted of fifty-three newly diagnosed and untreated women aged between 18 and 62 years with IDA. Group 1 consisted of 33 patients, platelet levels below 400 x 10(9)/L. Group 2 consisted of 20 patients, platelet levels above 400 x 10(9)/L. Measurements of plasma viscosity were performed using Brookfield viscometer. RESULTS: Mean plasma viscosity was found as 1.05 ± 0.08 mPa.s. in Group 1, and 1.03 ± 0.06 mPa.s. in Group 2. Mean plasma viscosity was not statistically different. White blood cell count was significantly higher in Group 2. Vitamin B12 levels were significantly higher in Group 2, while folic acid levels were higher in Group 1 (p=0.011 and p=0.033). Plasma viscosity was correlated with erythrocyte sedimentation rate (r=0.512 p=0.002) in Group 1 and inversely correlated with vitamin B12 (r=-0.480 p=0.032) in Group 2. CONCLUSION: Despite the significant difference between groups in terms of platelet count, no significant difference was detected in plasma viscosity and this finding could be explained as the following; 1-These platelets were not thrombocythemic platelets; 2-Similar to the theory about leukocytes, higher platelet counts - even non-thrombocythemic - may increase plasma viscosity; 3-Evaluating platelet count alone is not sufficient and the associating red-cell deformability should also be taken into account; and 4-Although other diseases that could affect viscosity are excluded, some definitely proven literature criteria such as fibrinogen, hyperlipidemia, and the inflammatory process should also be evaluated by laboratory and clinical measures.

ABSTRACT

INTRODUCTION: Early diagnosis of acute meningitis has paramount importance in clinical practice because of mortality and morbidity of the disease. Examination of cerebrospinal fluid (CSF) has critical value for the diagnosis of acute meningitis and discrimination of bacterial and aseptic meningitis. It has been previously reported that plasma viscosity can be used as an inflammatory marker. In this study we aimed to evaluate the role of CSF viscosity as a complementary measure for diagnosis of meningitis in suspected patients. METHODS: Forty-one consecutive patients who underwent lumbar puncture to rule out meningitis were studied prospectively. Twenty-seven patients were diagnosed with meningitis, of whom 13 patients had aseptic meningitis and 14 patients had bacterial meningitis. Meningitis was ruled out in 14 patients. RESULTS: CSF protein and CSF viscosity were significantly higher in patients with meningitis compared to nonmeningitis. Receiver operator characteristic (ROC) analysis revealed that CSF viscosity was highly sensitive (100%) and specific (93%); measures for the diagnosis of meningitis in the study population was comparable to those of CSF protein. Additionally, patients with meningitis were also divided into two groups as having bacterial and aseptic meningitis. CSF viscosity also significantly differed between bacterial and aseptic meningitis. CONCLUSION: The CSF viscosity is a simple and easy method and can be used as an adjunctive measure for the diagnosis of meningitis. With the support of further and larger clinical studies, CSF viscosity may have a role in the discrimination of bacterial versus aseptic meningitis.

ABSTRACT

BACKGROUND: Markers of platelet activation and haemorrheological indices have been demonstrated to play a role in the pathophysiology of atherosclerosis and cardiovascular events. In this study, we aimed at investigate the association between plasma viscosity and platelet indices in patients undergoing coronary angiography. MATERIALS AND METHODS: Three hundred and eighty four consecutive patients scheduled to undergo coronary angiography were included in the study. Prior to coronary angiography, blood samples were withdrawn to determine routine biochemical markers, blood cell analyses and viscosity measurements. According to the results of coronary angiography, patients were classified either in a subgroup with coronary artery disease (CAD; 1 or more stenoses >50%) or normal coronary arteries (NCA; no stenoses or <50%). RESULTS: There was a statistically significant correlation between plasma viscosity and mean platelet volume levels in all patients undergoing coronary angiography (r=0.199, p<0.001). Additionally, when correlation analysis was performed within each group, plasma viscosity significantly correlated with MPV both in patients with CAD (r=0.18, p=0.004) and in patients with NCAs (r=0.272, p=0.002). Linear regression analysis revealed that plasma viscosity was positively associated with MPV while platelet number was inversely but significantly associated with MPV. CONCLUSION: We have shown for the first time that MPV correlates with plasma viscosity in patients undergoing coronary angiography, suggesting a relation with plasma proteins and activation of circulating platelets or peripheral consumption of platelets. To evaluate this relation further controlled studies also in patients with acute coronary syndromes are warranted.

ABSTRACT

OBJECTIVE AND BACKGROUND: Determining the aetiology of an effusion involves assessing if it is an exudate or a transudate. However, a reliable test for determining the aetiology of a pleural effusion is lacking. Pleural viscosity has a high sensitivity and specificity and a high positive and negative predictive value for discriminating exudative and transudative pleural effusions. The aim of this study was to use pleural fluid viscosity to discriminate between various aetiologies of exudative effusions, namely malignant, parapneumonic and tuberculous. METHODS: Seventy consecutive patients (24 women, 46 men, mean age = 67 years) with exudative pleural effusion due to pneumoniae in 24 patients, tuberculous pleurisy in 21 and lung cancer in 25 were studied prospectively. Measurements of pleural fluid and plasma viscosity were performed using Brookfield DV-II viscometer. RESULTS: Pleural viscosity and pleural LDH were highest in the tuberculous pleurisy patients and lowest in the lung cancer patients. Pleural viscosity > or = 1.57 was found to be indicative of tuberculous pleurisy with a sensitivity of 100% and specificity of 95%. Pleural viscosity < 1.39 was found to be indicative of lung cancer with a sensitivity of 100% and specificity of 94%. Pleural viscosity was significantly correlated with pleural albumin (r = 0.34, P = 0.004), protein (r = 0.40, P = 0.001), LDH (r = 0.70, P < 0.001) and plasma viscosity (r = 0.44, P < 0.001), having the most significant value with pleural LDH. CONCLUSION: The pleural fluid viscosity of patients with parapneumonic, tuberculous and malignant effusions are significantly different from each other. Among these groups, tuberculous effusions had the highest viscosity, and malignant effusions from lung cancer the lowest.

ABSTRACT

BACKGROUND: The initial step in establishing the cause of an effusion is to determine whether the fluid is a transudate or exudate. Plasma viscosity is influenced by the concentration of plasma proteins and lipoproteins with the major contribution resulting from fibrinogen. In this study we aimed to evaluate the role of pleural fluid viscosity in discrimination of transudate and exudates. MATERIALS AND METHODS: We studied prospectively 63 consecutive patients with pleural effusion in whom diagnostic or therapeutic thoracentesis had been performed. The criteria of Light were applied to differentiate transudates from exudates: 33 patients (23 male, 13 female, mean age=68+/-4 years) had exudates and 30 patients (17 male, 13 female, mean age=68+/-5) had transudates (due to congestive heart failure). Measurements of pleural fluid and plasma viscosity were performed using a viscometer. RESULTS: There was no statistically significant difference between patients with transudate and exudates in respect to plasma viscosity. However, pleural viscosities of the patients with exudates were significantly higher than those of patients with transudate (1.37+/-0.16 mPa vs 0.93+/-0.03 mPa s p<0.001, respectively). Pleural viscosity has a high sensitivity, specificity (94%, 93%, respectively), positive and negative predictive value (97%, 97%, respectively) for the discrimination of transudative or exudatetive pleural fluid. CONCLUSION: We have demonstrated for the first time that pleural viscosity of the exudative effusion is higher than that of transudative effusion with high sensitivity, specificity, positive and negative predictive value. Regarding the simplicity of this measurement, it may play a valuable role in the accurate and fast discrimination of pleural fluid.

ABSTRACT

OBJECTIVE: To study, the impact of thrombophilia caused by Factor V, Factor ll G20210A mutations on recurrent abortions, the prevelance of Factor V Leiden and Factor II G20210A mutation in patients with habitual abortions. METHODS: Forty one patients with a diagnosis of habitual abortion were enrolled in the study. Control group consisted of 50 women without a history of poor obstetric outcome. 10 ml. peripheral venous blood was taken from study and control groups and transferred to EDTA tubes, and were tested for Factor V Leiden and Factor II G20210A mutations by PCR in genetics laboratory. RESULTS: Phenotypes of 91 cases were determined by PCR for Factor V Leiden. It was established that of 41 patients in the study group, 31 (75.6%) had GG genotype, 9 (22%) had GA genotype and 1 (2.4%) had AA genotype. In the control group, 45 (90%) of 50 women had GG genotype and 5 (10%) had GA genotype. A allele carrier status was found to be 24.4% in study group and 10% in the control group. The difference between them was not statistically significant (p = 0.06). CONCLUSIONS: The results obtained from patients and control group have no difference in Factor V Leiden and Factor II G20210A mutations.These results suggest that mutations have no role in etiology of 1. and 2. trimester recurrent abortions.

ABSTRACT

INTRODUCTION: Apheresis is a procedure in which one of the components of blood is removed. The aim of therapeutic plasma exchange (TPE) is to remove a large fraction of the patient's plasma from the body, and to exchange this with replacement solutions using automatic devices. With this procedure circulating pathogens and toxins are reduced. Before each TPE results of a baseline basal complete blood count, serum protein electrophoresis, coagulation tests and serum electrolytes must be known. The efficacy of this therapy is assessed only by these values. The proteins responsible for disease may be monoclonal proteins, cryoglobulins, lipoproteins, auto or allo antibodies or toxins. In this study, we aimed to compare the effects of several replacement fluids on plasma viscosity and oncotic pressure. At the same time, we evaluated the correlation between plasma viscosity and oncotic pressure. MATERIAL AND METHODS: 111 TPE were performed on 42 patients. Before TPE, the patients whose veins were not suitable were catheterised either by using a subclavian or jugular 11F dialysis catheter. At each session, approximately 1-1.5L of plasma was exchanged. The procedure was performed with albumin in patients whose albumin was under 3gr/dl. Over this value, the exchange fluids were randomised. RESULTS: When the overall results were analysed, there was no statistically significant difference between groups 1 (HES+albumin) and group 3 (albumin). The statistical difference between group 2 and 3 was significant, but no difference was observed between group 1 and 2. According to the decreasing plasma viscosity, there was a significant difference between group 2 and group 3, but there was no difference between group 1 and group 2. CONCLUSIONS: The replacement solutions used for plasmapheresis are similar when compared for hemorheologic effects, but we have chosen fresh frozen plasma because of fewer side effects.

ABSTRACT

Plasmapheresis is a widely used alternative treatment for several diseases. Recently, synthetic plasma expanders have been used to reduce the cost of therapeutic plasma exchange (TPE). Hydroxyethyl starch (HES) is a polysaccharide colloid. Isohes and Varihes are plasma volume expanders containing 6% HES in 0.9% NaCl solution. In this study, we aimed to compare the effects of several replacement fluids used for TPE on plasma viscosity profile. At the same time, we evaluated the correlation between plasma viscosity and fibrinogen level. Twenty-nine patients were enrolled for this study. Patients were divided into four groups based on replacement fluids used: 3% HES + 4% albumin (group 1), FFP (group 2), 3% Varihes (450000/ 0.7)/Isohes(200000/0.5) (group 3), and 4% albumin (group 4). The choice of replacement fluids used was randomly assigned, as long as there were no contraindications for the patient. Seven samples were collected to determine plasma viscosity and fibrinogen level during TPE cycles. There was a positive exponential correlation between plasma viscosity and fibrinogen levels. At the second plasmapheresis procedure, plasma viscosity and fibrinogen levels decreased by 20% compared with first cycle. The effect of plasmapheresis solutions on hemorheology were roughly the same. Effects of replacement fluids on plasma viscosity were comparable.

ABSTRACT

BACKGROUND: The number of therapeutic procedures is increasing steadily year by year with growing collaboration of departments other than Hematology. In the aim to demonstrate our single center activity we analyzed our data since four years. METHODS: Between years 1998 and 2001, 658 therapeutic plasma exchange (TPE) procedures were performed on 158 patients. Median age and male/female ratio were 37 (range, 15-87) and 80/78, respectively. Main indications were myastenia gravis (n=55, 34%), TTP (n=13, 8.5%), post ABO mismatched allogeneic hematopoietic cell transplantation aregeneratoric anemia (n=6, 7.5%), progressive systemic sclerosis (n=10, 6.5%), multiple myeloma (n=10, 6.5%), Gullian Barre Syndrome (n=9, 5.9%), multiple sclerosis (n=7, 4.6%), Waldenström Macroglobulinemia (n=5, 3.4%), polymyositis (n=4, 2.7%), sepsis and disseminated intravascular coagulation (n=4, 2.7%). Departments who referred the majority of the patients for TPE were neurology (n=199), hematology (n=153), immunology (n=78), intensive care unit (n=78) and thorax surgery (n=51). RESULTS: The median TPE procedure per patient was 4 (range, 1-50). All the procedures were performed on continuous flow cell separators and median plasma volume processed per cycle was 2471 ml (range 436-5000). The replacement fluids used were 3% hydroxyethylstarch (HES) (24%), 5% albumin (35%), fresh frozen plasma (25%), and HES and albumin (16%). HES was tolerated well even as a sole replacement fluid with acceptable minor side effects. In three patients with progressing hypoalbuminemia HES was replaced or combined with 5% albumin. Close monitoring of serum albumin and fibrinogen levels after repeated procedures is mandatory. CONCLUSION: In our four years of TPE experience we have increased our collaboration with other departments. 3% HES+/-5% Albumin is a feasible, well tolerated and cost effective replacement fluid combination especially for short-term plasma exchange therapy.

ABSTRACT

Therapeutic apheresis is a widely used treatment alternative for several diseases. In 29 patients with different diseases, we have monitored the PT, aPTT, thrombin time (TT), fibrinogen, D-dimer, factor VIII, IX, X, XI, XII, VWF, Protein C, S, Active Protein C Resistance (APCR) and Antithrombin-III during TPE. Patients were divided into four groups based on the replacement fluids used: 3% VARIHES or ISOHES + 4% albumin (1:1) (group 1), fresh frozen plasma (FFP) (group 2), 3% VARIHES or ISOHES (group 3) and 4% albumin (group 4). In our study, the fibrinogen level decreased to 83% of the base line level after the end of 48 h therapy. The APTT, PT, and TT increased during TPE. However no statistical difference was observed between the groups. We found a significant change in factor levels with time, only the difference in factors IX and XI between the groups was significant. In addition, factor levels measured at 48 h were close to the levels measured before aphereses. In our study, time the related change in AT-3 values was significant. Time-related changes of the Protein S and APCR were not statistical significant significant but on the other hand, we found a significant difference in AT-III and Protein C values between groups. The side effects of HES on coagulation factors and tests were comparable to those of other replacement fluids. Its low cost makes it favourable.
