Does the platelet­to­lymphocyte ratio have a prognostic effect in patients with myelodysplastic syndrome?

INTRODUCTION: Myelodysplastic syndromes (MDS) include various hematologic abnormalities characterized by chronic cytopenia due to disruption in cellular differentiation. This study aims to evaluate the prognostic value of PLR in patients with MDS. MATERIAL AND METHODS: Clinical-laboratory findings and the results of bone marrow biopsies of MDS patients before treatment were recorded. p value of <0.05 was considered statistically significant. SPSS version 20.0 was used for statistical analysis. RESULTS: The study included 62 patients with median follow-up time of 62.8±4.5 months and median age of 68.5 years. In 13 patients, acute leukemia was transformed. In these subjects, a PLR cut-off level of 46 was established for mortality (p=0.015). We found a significant relationship between PLR and multilineage series with the presence of dysplasia (p=0.017). The survival analysis showed a decreased survival in cases with dysplasia in two and/or more series, transformation into acute leukemia, and thrombocytopenia. CONCLUSION: Our study demonstrated that there was a relationship between PLR and MDS with multilineage dysplasia (mld-MDS). PLR is investigated as an inflammatory finding in various hematologic malignancies. Further studies investigating the value of PLR in MDS are needed to determine whether PLR may be a marker of bone marrow dysplasia grading (Tab. 2, Fig. 4, Ref. 32).

In myelodysplastic syndrome cases, what should be the level of ferritin which has prognostic value?

OBJECTIVES: Myelodysplastic syndrome (MDS) is a highly mortal disease in which anemia is unresponsive to treatment. In this study, the effect of basal ferritin values on prognosis and survival was investigated in MDS patients without history of transfusion. METHODS: Data were retrospectively analyzed for 62 MDS cases. The cases were divided into two groups according to ferritin values. RESULTS: The mean survival time was 61.1±4.8 months. During the follow-up period, 34 (54.8%) patients deceased. Median ferritin level was 358ng/mL. The serum ferritin (SF) level associated with mortality was determined as 400ng/mL (ROC area for SF was 0.731 with a cutoff value of 400; sensitivity and specificity were 70.7% and 68.2%, respectively) (P=0.002). There were 29 (46.8%) patients with serum ferritin levels of ≥400ng/mL. Patients with serum ferritin levels≥400ng/mL had low survival rates. Ferritin≥400ng/mL was associated with six times increased mortality (P=0.001). CONCLUSION: Although the acceptable ferritin level at the start of chelation therapy is 1000ng/mL, the fact that 400ng/mL value is associated with survival in our study suggests that it may be useful to start chelation therapy in the early period. Further case studies on the subject are required.

Occult urinary incontinence in elderly women and its association with geriatric condition.

OBJECTIVE: Many older women are hesitated to initiate discussions about urinary symptoms and their incontinence. The aim of this study is to determine the prevalence of occult urinary incontinence in outpatient older women and to evaluate its association with other geriatric conditions. PATIENTS AND METHODS: 100 female patients 65 years and older were assessed at the geriatric outpatient clinic. The validated form of the Turkish version of the International Consultation on Incontinence Questionnaire-Short Form was used to evaluate urinary incontinence and quality of life. Comprehensive geriatric assessment including activities of daily living, instrumental activities of daily living, mini mental state examination and geriatrics depression scale was performed. The number of falls, comorbid conditions and number of medications were noted. The association between urinary incontinence and geriatric domains were evaluated with logistic regression analysis. RESULTS: A total of 100 patients were evaluated, 64 of them included in the study. The median age of patients was 72.5. The rate of urinary incontinence was found 40.6%. The association between urinary incontinence and quality of life, performance status and comorbidity was found statistically significant with logistic regression (p = 0.033, p = 0.005, p = 0.031 respectively). Half of the patients with UI believe that it is part of normal aging and no definite treatment is available. CONCLUSIONS: Occult urinary incontinence is a significant problem in older women that inversely affecting the quality of life. The study suggests that awareness and education regarding incontinence should be increased among elderly patients and screening of urinary incontinence is an important part of the geriatric assessment. The evaluation and management of functional status and comorbid conditions should be the initial step during incontinence management in elderly patients.

Prognostic significance of flow cytometry findings in Turkish adult acute leukemia patients.

OBJECTIVE: Several factors are known to affect prognosis of acute leukemia such as age, high leukocyte count, cytogenetic abnormality, performance status and recurrent leukemia. We aimed to investigate the association between cell surface markers and prognostic determinants such as recurrence at 6 and 12 months and survival at 6, 12 and 18 months in acute leukemia patients. PATIENTS AND METHODS: A total of 142 patients, 101 with acute myeloid leukemia (AML) and 41 with B-cell acute lymphoblastic leukemia (B-ALL) were included. The effects of surface markers on survival and recurrence rates were evaluated retrospectively. RESULTS: In AML patients, CD5+ and CD34+ immunophenotypes and in ALL patients cCD22+, CD34+ and CD49f + CD19+ immunophenotypes were positive prognostic indicators. In AML patients CD7 expression, and in ALL patients CD5+, CD7+ and CD117+ immunophenotypes and >90% CD45 expression were negative prognostic indicators. CONCLUSIONS: This study demonstrates that flow cytometry, a common diagnostic tool in acute leukemia, may also have prognostic value in acute leukemia in the future.

The status of iron absorption in older patients with iron deficiency anemia.

OBJECTIVE: The aim of this study is to evaluate the iron absorption status by using the oral iron absorption test (OIAT) in older patients with iron deficiency anemia (IDA) in comparison with younger patients. PATIENTS AND METHODS: This is a cross-sectional study including 100 patients with iron deficiency anemia. Patients were divided in two groups; group 1 who is 65 and older and group 2 who is younger than 65. OIAT in which a fasting serum iron level is compared with a second serum iron level obtained three hours following oral ingestion of iron sulfate was performed. An increase in serum iron of at least 100 mcg/dL indicates that oral iron absorption is adequate. The Independent-Samples t-test was used to show the statistical difference between the means of two groups. RESULTS: There were 100 patients in the study; 69 of them have completed the study. The means of the oral iron absorption test results of the groups was compared with an independent t-test, which showed that the mean of group 1 was lower than group 2 and this was statistically significant (p = 0.001). The mean of OIAT results was 86.1 and 163.5 in group 1 and 2 respectively. CONCLUSIONS: In our knowledge, the present study is among the first that shows the status of iron absorption objectively by using OIAT in older patients. Our study shows iron absorption is decreased in older patients with IDA in comparison with younger patients. In the light of this finding; OIAT should be offered before initiating treatment in older patients when IDA is diagnosed and intravenous iron treatment should be considered more on the base of results.

The predictive value of epidemiological characteristics, clinical and laboratory findings in adult lymphadenopathy etiology.

OBJECTIVE: Our aim was to determine the presence or absence of malignant etiology in the epidemiological, clinical and laboratory results of patients undergoing lymph node biopsies. PATIENTS AND METHODS: This study was carried out between January 2013 and April 2014. We enrolled a total of 150 adult patients who had lymph node biopsies. 73 of these were females (48.7%) and 77 were males (51.3%). The epidemiological characteristics, clinical and laboratory findings were evaluated and compared with the pathological results. RESULTS: Leukopenia (p=0.05) thrombocytopenia (p=0.03) and increased lactate dehydrogenase levels (p=0.01) were found to be associated with the malignancy. In the cervical, submandibular, axillary and inguinal areas lymphadenopathy was generally seem to be benign while the rate of malignancy was higher in the intra-abdominal and supraclavicular regions. In those cases who had a lymph node index of below 2 there was a higher rate of malignancy (p=0.04). In cases which lymphadenopathy accompanied by splenomegaly has been found associated with malignancy (p=0.009). No association with regards to malignancy was found with the erythrocyte sedimentation rate, C-reactive protein and hepatomegaly. CONCLUSIONS: According to the results of the study five variables including cytopenia, lactate dehydrogenase levels, splenomegaly, lymph node index below 2, intra-abdominal and supraclavicular lymphadenopathy were concluded to be the most suitable means of predicting malignant etiology.

Evaluation of serum levels of zinc, copper, and Helicobacter pylori IgG and IgA in iron deficiency anemia cases.

OBJECTIVE: Iron deficiency anemia (IDA) is the most common form of anemia. Impaired intake absorption and blood loss are the main factors in the etiology. Impaired absorption can be caused by a decrease in trace elements such as copper and zinc, which are found in the structure of enzymes that coordinate iron metabolism or act as a catalyst for them, and the existence of Helicobacter pylori (H. pylori), which inhibits iron absorption in the stomach. Serum levels of zinc, copper, and H. pylori antibodies were measured in IDA cases, and correlations with IDA were evaluated. PATIENTS AND METHODS: The study group was composed of 115 IDA cases who were followed at hematology outpatient clinics, and the control group was composed of 92 gender- and age-matched healthy individuals. Patients were diagnosed with iron deficiency anemia according to hemoglobin, serum ferritin, and iron levels and total iron-binding capacity. Serum zinc, copper, H. pylori immunoglobulin A (HpIgA) and immunoglobulin G (HpIgG), vitamin B12, and folic acid levels were examined in the blood specimens collected. RESULTS: No statistically significant difference in zinc and copper serum levels between the study and control groups was observed (p > 0.05 for both groups). Although no difference was observed between the HpIgG levels of the two groups, patients with IDA had a statistically significant increase in HpIgA levels (p < 0.05). Pearson's correlation analysis showed that the zinc levels of the IDA group did not have a correlation with any parameters (p < 0.05 for all). Copper levels had a positive correlation with only the HpIgA level in the IDA group (r = 0.222, p = 0.017). CONCLUSIONS: Trace elements and H. pylori infection did not have a correlation with IDA. Elevated levels of HpIgA and positive correlation of HpIgA with copper levels were observed. The literature review clearly suggests that several points require further explanation, and extensive research with larger samples is required.

A forgotten screening test for iron deficiency anemia: oral iron absorption test.

OBJECTIVE: In this study, we aimed to investigate the iron absorption defects using the oral iron absorption test (OIAT) in patients with iron deficiency anemia (IDA). MATERIALS AND METHODS: Forty-six patients with IDA which nonresponder to oral iron treatment were included in the study. OIAT was started at 8 a.m. after an overnight fast; 52.8 mg of elemental iron were given orally as 160 mg of iron sulfate. Iron levels of all participants were analyzed at baseline and at the 3rd hour of the study. RESULTS: Compared to baseline; serum iron levels whose serum iron levels exceed 91 mcg/ dl in 40(%87) patients. Further investigations in 6 patients revealed that 4 patients had chronic atrophic gastritis with helicobacter pylori infection; while the remaining 2 patients did not have any prominent. CONCLUSIONS: This study demonstrated that OIAT is a good index for the evaluation of absorption defects and can be a screening clinical test of IDA.

Diffuse plasma cell infiltration of liver detected initially at diagnosis of multiple myeloma.

Liver involvement in mutiple myeloma (MM) is not commonly encountered. In this report, we describe a patient who was diagnosed with IgG kappa type MM. A liver biopsy revealed monoclonal plasma cell infiltration. Hepatomegaly was the sole finding in physical examination and the liver function tests were not disturbed.

A patient with massive hemoptysis treated by videothoracoscopic clipping of the causative aberrant artery.

Massive hemoptysis is a life-threatening situation and can have a variety of underlying causes. Bronchial arteries are mostly the source of bleeding but in rare cases an aberrant systemic artery may be present, causing hemoptysis. Here, we present a patient in whom an aberrant systemic artery was defined to be the cause of hemoptysis. Obstruction of this artery by videothoracoscopic clipping was curative for the patient's hemoptysis.

Hematological malignancy and pregnancy: a single-institution experience of 21 cases.

The incidence of hematological malignancies during pregnancy is low, and treatment in this setting is problematic. This study observed 21 pregnancies in 18 patients with hematological malignancies. Patients' ages were between 19 and 43 (median 25) years. Two pregnancies ended with spontaneous abortion, one pregnancy ended with in utero death, three therapeutic abortions were carried out, and 15 infants were born alive but three of them died later. The median birth weight was 2.47 kg. Twelve babies survived to a median age of 36 (range 4-117) months. Eight babies were exposed to chemotherapy during the in utero period. One baby was exposed to chemotherapy during all the trimesters and was born prematurely and later died because of intracranial bleeding. Four babies were exposed to chemotherapy during the first trimester, one of them had low birth weight and floating thumb malformation, two of them had only low birth weight, and one was born healthy, but died at 3 months of age as a result of severe gastroenteritis. Two babies were exposed to chemotherapy during the second and third trimesters; one of them had low birth weight, and the other pregnancy ended in in utero death. One infant was exposed to chemotherapy during the third trimester and was born at term, but died because of pulmonary hemorrhage. We concluded that chemotherapy during all trimesters of pregnancy carries a significant risk for an unfavorable outcome.

Effect of valsartan on erythropoietin and hemoglobin levels in stage III-IV chronic kidney disease patients.

Angiotensin-converting enzyme inhibitors (ACEIs) were accepted as a potential cause of inadequate epoetin response in chronic kidney disease (CKD) patients. We aimed to determine the effects of valsartan, an angiotensin receptor blocker (ARB), on serum ertyhropoietin levels and on certain biochemical and haematological parameters in hypertensive CKD patients. Twenty-two stage III-IV CKD patients (mean age; 56.8 +/- 8.9 years, 12 male 10 female) were included in the study. Before initiating the treatment, current anti-hypertensive treatments (if any) were discontinued, and blood samples were collected after a washout period of 3 weeks. Valsartan 80 mg/day was started, and additional anti-hypertensive agents were given according to study protocol if needed. One way Anova and paired t-tests were used for statistical comparisons. Serum blood urea nitrogen (BUN), creatinine, uric acid, potassium, haemoglobin and erythropoietin values were measured, and glomerular filtration rates were calculated before and 3, 6 and 90 days after valsartan treatment, a significant reduction in EPO level was observed at 3rd (19.6 +/- 24.0 vs. 13.8 +/- 8.5, p = 0.010), 6th (12.1 +/- 7.6, p = 0.009), and 90th days (8.3 +/- 5.4, p = 0.007). When pre-treatment values were compared with 90th day results, no significant change was observed in terms of hgb, htc, serum BUN, creatinine, uric acid, potassium, and GFR values. In conclusion, valsartan, an ARB, did not decrease haemoglobin levels in stage III-IV CKD patients despite significant reduction in serum erythropoietinlevels, so ARBs may be preferred to ACEIs in CKD patients when indicated.

Microalbuminuria in Hodgkin's disease.

In some malignant disorders, it was reported that urinary albumin excretion (UAE) was correlated with the prognosis and the extent of the disease. In this study, 24-h UAE was determined in 34 Hodgkin's disease patients without prior treatment and 19 healthy controls. Microalbuminuria (MAU) was defined as UAE > or = 20 microg/min. In patients with MAU, UAE was determined again after the treatment. Mean UAE was 31.2 microg/min in the patient group and 5.6 microg/min in the controls (p = 0.005). Whereas MAU frequency was 47% in the patients, there was no MAU in the controls. Mean UAE tended to be higher in advanced stage patients compared to early stage patients (p = 0.051). Also, MAU frequency tended to be higher in the advanced stage group compared to the early stage group (p = 0.196). In four patients in whom remission could not have been achieved, although UAE was reduced, MAU did not disappear. In conclusion, UAE was increased in Hodgkin's disease. However, there is no significant correlation between UAE and the disease extent.

CA 125 levels in patients with non-Hodgkin lymphoma and other hematologic malignancies.

Cancer antigen (CA 125) is a glycoprotein commonly used as a tumor marker. In this study, CA 125 levels were measured in 149 patients and 26 healthy control subjects. The study group included 69 non-Hodgkin lymphomas (NHL), 25 Hodgkin disease (HD), 20 acute myelocytic leukemia (AML), 14 chronic lymphocytic leukemia (CLL), 12 chronic myelocytic leukemia (CML), and nine multiple myeloma (MM) patients. CA 125 was elevated in 37 of the patients and in none of the control subjects. Average CA 125 level in NHL patients was significantly higher than the controls (56.2 +/- 9.2 U/ml, 7.99 +/- 1.05 U/ml respectively) (P < 0.05). CA 125 levels were significantly higher in NHL patients with abdominal involvement (113.6 +/- 23.4 U/ml), with B-symptoms (72.3 +/- 13.2 U/ml), higher stage of the disease (stages III and IV -75.3 +/- 14.9 U/ml), bulky disease (99.9 +/- 30.4 U/ml) and in those with serosal involvement (103.1 +/- 18.5 U/ml) (P < 0.05 for all). CA 125 levels were also elevated in seven patients with HD and in a patient with CLL with pleural effusion. In conclusion, for patients with NHL, high levels of CA 125 were associated with B-symptoms, advanced stage, bulky disease, abdominal, and serosal involvement. Therefore, CA 125 might be used as a marker to predict prognosis and to detect advanced disease in NHL.

Autonomic dysfunction in multiple sclerosis: correlation with disease-related parameters.

Cardiovascular autonomic functions were investigated in a prospective, controlled study of 22 consecutive relapsing-remitting multiple sclerosis (MS) patients and 22 healthy subjects using 5 simple noninvasive tests and sympathetic skin response testing. Tests included the heart rate response to deep breathing, valsalva maneuver and standing, blood pressure response to standing and sustained hand grip, and were graded according to the Ewing and Clark classification as early, definite or severe impairment. The relationship between autonomic dysfunction and disease-related parameters such as the expanded disability status scale (EDSS) and disease duration was studied. Ninety percent of the patients had symptoms related with autonomic dysfunction, and 45.5 % had abnormal results in cardiovascular autonomic function testing with 4 patients also having abnormal sympathetic skin responses. Statistical analysis indicated that patients with a long disease duration rather than high EDSS carried a risk of autonomic involvement in MS. Both parasympathetic and sympathetic functions were impaired and this could have been easily overlooked by a standard EDSS follow-up. In this regard, autonomic function testing seems necessary in order to detect subclinical changes in MS patients and should be considered in outcome measures.

The effect of G-CSF on lymphocyte subsets and CD34+ cells in allogeneic stem cell transplantation.

The effect of granulocyte colony-stimulating factor (G-CSF) on peripheral blood lymphocytes (PBL) and CD34+ cell frequency in the apheresis product has been determined in 25 healthy stem cell donors. Peripheral blood mononuclear cells (PBMNC) were collected after five days of G-CSF 10 microg/kg/day s.c., which was well tolerated. The median number of leukocytes increased eight-fold over that of pretreatment levels. Collection of PBMNC lasted a median of two (range, 1-3) days. The mean mononuclear cell (MNC) count and total lymphocyte percentage were 6.69 x 10(8)/kg and 59.08%, respectively, and the frequency of CD34+ cell expression was 2.1% in the apheresis product. The frequency of CD3+, CD4+, CD25+, NK and CD122+ cell expressions in mobilized PBMNC and PBL showed no significant difference. However, the frequency of CD8+, CD8+28+, CD3+DR+, CD19+, CD20+ and CD22+ B cells expression in the apheresis product increased significantly compared to steady-state PBL. In contrast, the frequency of the CD11 a+ and CD8+38+ cell expressions in the apheresis product was decreased compared to the steady-state PBL. The mean yield of CD34+ and CD3+ cells were 13.6 x 10(6) and 2.69 x 10(8)/kg of recipient body weight (RBW), respectively. Following allograft all patients engrafted with >0.5 x 10(9)/l neutrophil and < or = 20 x 10(9)/l platelets on a median of day 13 and 12, respectively. Nine patients had grade II-IV acute GVHD and chronic GVHD occurred in eight patients. Four patients died due to transplant-related complications. There was one late engraftment failure which occurred on the fifth month. Thirteen patients are still alive. In conclusion, these results indicate that administration of G-CSF at 10 microg/kg/day in normal donors alters the lymphocyte subsets and there are significant differences in the lymphocyte contents of the recipients before apheresis and in apheresis product.

Polyserositis as a rare component of polyglandular autoimmune syndrome type II.

Polyglandular autoimmune (PGA) syndromes (types I and II) may affect various endocrine and non-endocrine organs in the body. In the commoner PGA type II, primary adrenal insufficiency, autoimmune thyroid disease and type I diabetes mellitus are the most frequent manifestations. Serositis with pericardial or pleural involvement is not a well known component of the disease. Here, we report a 21-year-old man who first presented with a pleuropericardial effusion and Graves' disease, and who then developed type I diabetes mellitus.

Head and neck granulocytic sarcoma with acute myeloid leukemia: three rare cases.

We conducted a retrospective review of pathology files and hospital records and identified three unusual presentations of granulocytic sarcoma associated with acute myeloid leukemia (AML) of the head and neck. At least one mass was observed on the skin of all three patients. A 17-year-old boy had masses in each temporal region that were accompanied by bilateral facial paralysis. He was administered chemotherapy and radiotherapy, but he died of infection secondary to a second relapse 29 months after the initial diagnosis. A 17-year-old girl had a tumor in the right parotid area. She received chemotherapy, but she died of infection and bleeding 2 months after the initial diagnosis. A 33-year-old man had numerous tumors widely disseminated over his skin. He received chemotherapy and was in remission 12 months after the initial diagnosis, but he eventually relapsed and died. Granulocytic sarcoma can be localized in unexpected regions, including the head and neck. This tumor is very often misdiagnosed as a malignant lymphoma, which leads to delayed treatment and a poor outcome. Therefore, clinical and histopathologic findings should be evaluated before any diagnosis of malignant lymphoma is pronounced. Immunohistochemical stains should also be performed on patients with suspected granulocytic sarcoma, and aggressive chemotherapy or immunotherapy should be administered. We believe that high-dose chemotherapy can improve survival rates in granulocytic sarcoma associated with AML.

Relationship Between Leptin Levels and Body Indexes in Patients with Haematologic Malignancy.

Leptin is a recently found hormone regulating body weight. In human obesity, this weight-regulating hormone level is in a positive correlation with FMI (fat mass index) and BMI (body mass index). In this study, we aimed to investigate the relation between serum leptin levels and BMI, PF (percentage fat), LMI (lean mass index), FMI and some other parameters of patients with haematologic malignant diseases. Fourty-four patients with haematologic malignant diseases and 25 healthy control group were taken into the study. In the comparison, there were no significant difference between the PF and FMI values of both groups, while the mean BMI and LMI values of the control group were significantly higher than that of the patient group. There was a positive correlation between leptin levels and BMI and FMI among parameters studied in our control group, whereas we couldn't demostrate any such correlation in patient group. We estimate that the alteration may be due to disturbances in the feed back mechanism developing in patient with haematologic malignancy.
