The Effectiveness of Biological Agents on Chronic Rhinosinusitis with Nasal Polyposis in Patients with Comorbid Asthma: A Multicenter Real-Life Study from Türkiye.

Background and Objectives: Real-life data on the efficacy of biologic agents (BAs) on asthma-comorbid CRSwNP are needed. Our primary goal is to investigate the effects of BAs on CRSwNP symptoms, as well as endoscopic and tomography scores. Our secondary goal is to show a reduction in the frequency of acute sinusitis exacerbations and the need for surgery. Materials and Methods: We conducted a multicenter, retrospective, real-life study. We screened the patients with asthma-comorbid CRSwNP treated with omalizumab or mepolizumab. A total of 69 patients (40 F/29 M; omalizumab n = 55, mepolizumab n = 14) were enrolled. We compared the visual analog scale (VAS), sinonasal outcome test-22 (SNOT-22), nasal congestion score (NCS), Lund-Mackay computed tomography score (LMS), and total endoscopic polyp scores (TPS) before and after BAs. We evaluated the endoscopic sinus surgery (ESS) and acute exacerbations of chronic rhinosinusitis (AECRS) frequencies separately, according to the BAs. Results: The overall median (min-max) age was 43 (21-69) years. The median (min-max) of biologic therapy duration was 35 (4-113) months for omalizumab and 13.5 (6-32) for mepolizumab. Significant improvements were seen in VAS, SNOT-22, and NCS with omalizumab and mepolizumab. A significant decrease was observed in TPS with omalizumab [95% CI: 0-4] (p < 0.001), but not with mepolizumab [95% CI: -0.5-2] (p = 0.335). The frequency of ESS and AECRS were significantly reduced with omalizumab [95% CI: 2-3] (p < 0.001) and [95% CI: 2-5] (p < 0.001); and mepolizumab [95% CI: 0-2] (p = 0.002) and [95% CI: 2-8.5] (p < 0.001), respectively. There was no significant difference in LMS with either of the BAs. Conclusions: Omalizumab and mepolizumab can provide a significant improvement in the sinonasal symptom scores. BAs are promising agents for CRSwNP patients with frequent exacerbations and multiple surgeries.

Epiregulin: A new prognostic molecule in non-Hodgkin lymphoma.

BACKGROUND: Epiregulin is a molecule that plays a role in cell proliferation, tumor development, inflammation, and angiogenesis in malignant diseases. AIM: Our study aims to reveal, for the first time, the predictive value of this molecule in non-Hodgkin lymphoma (NHL) and its association with disease stage, cell type, and extranodal involvement. METHODS: The study is an observational case-control trial involving 60 newly diagnosed NHL patients and 60 healthy individuals (control group) between 18 and 75 years old. Demographic characteristics of all volunteers, stages of patients' illnesses and lymphoma cell types, hemogram, biochemistry tests, beta 2-microglobulin, C-reactive protein (CRP), and epiregulin levels were measured and statistically evaluated. RESULTS: Epiregulin levels were significantly higher in NHL patients compared to the control group (P < 0.0001). Similarly, a significant increase in epiregulin levels was observed in advanced NHL patients. Furthermore, the most common NHL subgroup within the NHL group, diffuse Large B Cell Lymphoma (DLBCL), and the subgroup with extranodal involvement also had significantly higher levels of epiregulin. A positive correlation was found between the epiregulin molecule and CRP, beta 2-microglobulin, and lactate dehydrogenase (LDH) levels in NHL patients. CONCLUSION: Our study suggests that serum epiregulin levels, discovered to increase in NHL patients for the first time, may be an independent predictive molecule in an advanced stage, extranodal involvement, and the DLBCL subtype of this disease. Epiregulin positively correlates with prognostic molecules such as beta 2-microglobulin, LDH, and CRP. Illuminating its potential role in NHL pathogenesis could make epiregulin a vital drug target for treatment.

An experience with plasma exchange treatment of acute lymphoblastic leukemia in a case with fulminant hepatitis related to L-asparaginase.

Acute lymphoblastic leukemia (ALL) is a malignant disorder resulting from the clonal proliferation of lymphoid precursors with arrested maturation. L-asparaginase is commonly used in combination chemotherapy of both pediatric and adult acute lymphoblastic leukemias. The most commonly encountered side effects of L-asparaginase are hypersensitivity reactions like pyrexia, urticaria, skin rash, and respiratory distress. There are also other side effects like anaphylaxis, coagulopathy, pancreatitis, thrombosis, and hepatic toxicity. Plasmapheresis can sometimes be appropriate to manage an overdose of drugs that circulate in the plasma compartment. We have reported plasmapheresis treatment of fulminant hepatitis in a patient with ALL after L-asparaginase treatment.

Soluble CD40 ligand, high sensitive C-reactive protein and fetuin-A levels in patients with essential thrombocythemia.

BACKGROUND: CD40 ligand (CD40L) is expressed on the surface of activated platelets and activated T lymphocytes. Circulating soluble CD40 ligand (sCD40L) is formed from these molecules proteolytically. Fetuin-A is a potent antiinflammatory cytokine. AIM OF THE STUDY: In this study, we aim to investigate sCD40L levels to determine whether there is platelet activation and to measure high sensitive C-reactive protein (hs-CRP) levels to demonstrate if this leads to an inflammatory process and also to study fetuin-A levels to see if there is any concomitant antiinflammatory event in patients with essential thrombocythemia (ET). METHODS: We compared 30 patients with essential thrombocythemia with 30 control subjects and in these patients we measured levels of sCD40L, hs-CRP and fetuin-A. RESULTS: sCD40L levels were significantly higher in the ET group compared to the control group (30.6±14.4 vs. 18.5±8.9, p=0.001). Although fetuin-A levels showed a slight trend to be increased in ET patients, the difference did not reach significance (4.5±4.2 vs. 3.2±2.1, p=0.158). There were no statistically significant differences in hs-CRP levels (24.6±4.9 vs. 25.0±5.2, p=0.750). CONCLUSION: sCD40L was significantly higher in patients with an ET without any association with an inflammatory process and we believe this may be a marker of platelet regeneration.

Comparative levels of macrophage migration inhibitory factor, procalcitonin, osteoprotegerin, interleukin-8, hs-C reactive protein, D-dimer in febrile neutropenia, newly diagnosed cancer patients, and infectious fever.

BACKGROUND: The purpose of this study is to determine the levels of procalcitonin (PCT), IL-8 (interleukin-8), MIF (macrophage migration inhibitory factor), osteoprotegerin (OPG), hs-CRP and D-dimer during fever above 38.3°C due to various causes. MATERIAL AND METHODS: Blood samples taken from a total of consecutive 65 hospitalized patients during fever were prospectively tested for hsCRP, PCT, IL-8, OPG, MIF and D-dimer. Of these patients, there were 26 patients presenting with chemotherapy-induced neutropenia who had no infectious agents found; 23 patients, who had a malignancy with a febrile episode which was neither a microbiologically documented infection nor a chemotherapy-induced neutropenia, and 16 patients who did not have a malignancy and were considered to have a clinically and microbiologically documented infection. RESULTS: IL-8 and D-dimer levels were higher in patients with febrile neutropenia than in the other two groups. Although MIF and OPG were higher in patients with newly diagnosed cancers, there were no differences among the three groups regarding PCT and hs-CRP values. CONCLUSION: High serum IL-8 and D-dimer levels can be useful markers to identify hospitalized chemotherapy-induced neutropenia patients. MIF and OPG were found to be higher in patients with newly diagnosed cancer.

The effects of lung involvement, clinical and laboratory parameters on outcome in elderly patients with coronavirus disease 2019.

We aimed to investigate the association of lung involvement and biochemical parameters with patients' demographic characteristics, and how this association effects the disease course and mortality in elderly patients diagnosed with coronavirus disease 2019 (COVID-19). Age, degree of pulmonary involvement, comorbidities, and biochemical parameters of 211 patients who were 60 years or older, diagnosed with COVID-19, and had lung involvement were analyzed. The effects of these parameters on ICU admission and mortality were investigated. Advanced age, severity of lung involvement, elevated D-dimer, ferritin, and fibrinogen levels, and a previous history ofchronic obstructive pulmonary disease (COPD)were significant for predicting ICU admission and mortality. Along with advanced age, both the severity of lung involvement and a history of COPD had major impact on mortality in the course of COVID-19.

Treatment of a patient with adnexal lymphoma with Rituximab.

Orbital lymphoma is a very rare type of primary Non-Hodgkin lymphoma. The disorder is often small B-cell lymphoma, although large cell morphology may also be identified in rare cases. It may sometimes be confused with non-malignant, benign-course lymphoid hyperplasia. Although involvement is usually unilateral (80%), bilateral cases are also reported. Response to radiotherapy is achieved in the majority of cases, whereas the prognosis is poor in orbital involvement with large cell lymphoma and response to combined chemotherapy is inadequate. In this paper, we report a case with a diagnosis of unilateral adnexal involvement, who previously received CHOP treatment and developed a relapse 6 months later, then responded to treatment with Rituximab.

Case report: blastic Mantle Cell Leukemia.

The patient, who was being followed up for Mantle Cell Lymphoma, was diagnosed with Mast Cell Leukemia 2 years after receiving R-CHOP treatment. The results of flow cytometry, which was performed upon determining leucocytosis and detecting blasts in the peripheral smear following the patient's presentation due to his poor general condition, was consistent with Mantle Cell Leukemia. This case is being presented since there are a very limited number of previously published cases on this topic.

Treatment of status epilepticus with plasmapheresis in a patient with thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is a syndrome with numerous neurological manifestations including altered mental status and seizures. However, status epilepticus (SE) has rarely been reported in this condition. Signs may be transient or fluctuate; however, permanent deficits do occur. Its prognosis was once considered uniformly poor, with a high mortality rate. Since the introduction of plasma infusions and exchanges, the prognosis of the disease has improved dramatically; remissions now occur in 80-90% of patients. Altered mental status in TTP often resolves with plasmapheresis. Likewise, we successfully treated a patient with thrombotic thrombocytopenic purpura (TTP) with pronounced clinical effects of status epilepticus with plasmapheresis and steroid treatment.

Comparison of conventional dose steroid treatment and high dose steroid treatment as run-in regime for splenectomy in immune thrombocytopenic purpura (ITP).

BACKGROUND: Splenectomy is a treatment procedure for ITP which is being used for more that 50years and is still considered as the best option for the treatment of the condition. The facts that frequent monitoring is not required and that medical treatment is not indicated following splenectomy in most cases are among the major advantages of the procedure. AIM OF THE STUDY: To compare the conventional dose steroid and high dose steroid treatments as run-in regime for splenectomy in patients diagnosed with ITP. METHODS: The conventional dose steroid (1mg/kg, n=20) and high dose steroid treatments (30mg/kg, n=30) were applied to 50 cases with ITP between 1998 and 2008 in our clinic. RESULTS: High dose steroid produced higher platelet count on days 3, 5, and 7 compared to conventional dose steroid. There were no differences between the groups in terms of adverse effects. Treatments were discontinued after the operation by rapidly reducing the dose. Postoperative values regarding response to splenectomy were comparable in both groups. CONCLUSIONS: Both higher and earlier responses obtained with high dose steroid may be significant in reducing hospitalization period of patients and eliminating life-threatening platelet values within the shortest time possible.

Serum homocysteine and asymmetric dimethylarginine levels in patients with premature ovarian failure: a prospective controlled study.

OBJECTIVE: To investigate serum homocysteine and asymmetric dimethylarginine (ADMA) levels in patients with premature ovarian failure (POF). STUDY DESIGN: A total of 69 women, 32 with POF and 37 apparently healthy women were included in the study. Fasting blood samples were drawn to measure serum homocysteine and ADMA levels using ELISA method. RESULTS: The study and control group had a mean age of 37.3 + 2.6, 37.5 + 2.5 years; a mean homocysteine level of 13.54 + 5.19, 12.71 + 3.99 mmol/l and a mean ADMA level of 1.32 + 0.27, 1.26 + 0.36 mmol/l, respectively. There were no statistically significant differences between the two groups in terms of homocysteine and ADMA levels (with p values of 0.465 and 0.423, respectively). A negative significant correlation was found between estradiol and ADMA (p <0.05). CONCLUSION: Homocysteine and ADMA levels did not change in comparison with the control group, which suggests that estrogen deficiency in patients with POF does not have any effect on homocysteine and asymmetric dimethylarginine levels.

Roles of certain biochemical and hematological parameters in predicting mortality and ICU admission in COVID-19 patients.

OBJECTIVE: In this study, we aimed to retrospectively analyze the roles of certain hematological and biochemical parameters in predicting mortality and intensive care unit admission in patients diagnosed with coronavirus disease 2019 (COVID-19). METHODS: We analyzed the complete blood count and biochemical parameters of 186 COVID-19 patients by using the polymerase chain reaction test. Whether these parameters can be used to predict intensive care unit admission and mortality in the COVID-19 patients was investigated. RESULTS: The complete blood count and biochemical parameters of COVID-19 patients and in those admitted to intensive care unit were compared. The red cell distribution width, ferritin, lactate dehydrogenase, D-dimer, C-reactive protein, prothrombin time, and creatinine levels were found to be the most significant parameters. We found that these parameters are significant for predicting not only intensive care unit admission, but also the mortality of the patients admitted to the intensive care unit. CONCLUSIONS: We determined that the most effective parameters to predict intensive care unit admission and mortality in COVID-19 patients are ferritin, lactate dehydrogenase, D-dimer, C-reactive protein, red cell distribution width, creatinine, and intensive care unit. Close monitoring of these parameters and early intervention in alterations are of vital importance.

Adhesion molecules before and after propylthiouracil in patients with subclinical hyperthyroidism.

OBJECTIVE: This study aimed to investigate the effect of propylthiouracil treatment on adhesion molecules in patients with subclinical hyperthyroidism. METHODS: In this study, a total of 168 patients diagnosed with subclinical hyperthyroidism were treated with propylthiouracil for one year. The levels of adhesion molecules, consisting of sICAM-1, sVCAM-1, and sE-Selectin, before and after the treatment were measured and compared. These results were compared with the levels of 148 healthy controls who received a placebo. RESULTS: sICAM-1 levels were significantly higher in subclinical hyperthyroidism patients than in healthy controls (*pa=0.000). sICAM-1 levels were significantly decreased after the treatment (**pb=0.000). Despite this decrease in patients with subclinical hyperthyroidism, it did not decrease to the level of the control group. sVCAM-1 did not change before and after propylthiouracil treatment. The level of sE-selectin was similar to that of the pretreatment control group, but it did not have statistical significance, although it increased after the treatment (**pb=0.004). CONCLUSION: The sICAM level was significantly higher than the pretreatment values and decreased after the propylthiouracil treatment. However, further studies are needed to reduce the risk of atherosclerosis and cancer in patients with subclinical hyperthyroidism.

Serum Annexin V and Anti-Annexin V levels and their relationship with metabolic parameters in patients with type 2 diabetes.

BACKGROUND: We investigated the serum annexin V and anti-annexin V levels and their relationship with metabolic parameters in patients recently diagnosed type 2 diabetic. METHODS: A total of 143 patients recently diagnosed type 2 diabetes and 133 control subjects were included in the study. Body mass index (BMI), hs-CRP, HOMA-IR, carotid intima-media thickness, and serum levels of annexin V and anti-annexin V were investigated. RESULTS: HOMA-IR, serum hs-CRP, and carotid intima-media thickness were found to be statistically significant. The Pearson correlation analysis revealed a statistically significant positive relationship between the carotid intima-media thickness and the annexin V level (r=0.29, p=0.006*). A statistically significant positive relationship was also detected between the Annexin V level and level of serum hs-CRP (r=0.29 p=0.006*). CONCLUSION: A positive relationship was observed between the carotid intima-media thickness and annexin V at the end of our investigation. In this regard, we also believe that serum levels of annexin V may be increased for cardiovascular protection in the elevation of carotid intima-media thickness.

Immunoadsorption method using immunoglobulin Adsopak in adult cases with ITP resistant to splenectomy and other medical therapies.

BACKGROUND: Despite all medical therapies and splenectomy performed, severe life-threatening thrombocytopenia persists in many adult patients. AIM OF THE STUDY: To evaluate the efficiency of Immunoglobulin Adsopak immunoadsorption method in eliminating circulating immunocomplexes and IgG from plasma in these cases. METHODS: The method of POCARD Ig-Adsopak Wide Spectrum was applied to four cases with severe thrombocytopenia (< or =20.000/microL) by treating with a daily plasma of 0.25-2 L for 6 days. Platelet counts were recorded at the beginning and during administration of the method. For long-term effects, the cases were called for monthly controls during which platelet counts were measured. RESULTS: Platelet counts of four cases started to increase on average as of the first day. On Day 11, the platelet count reached 50.000/microL. On the following days (Day 17), platelet count was recorded as 90.000/microL. Cases were followed up for a mean of 2 years. At the end of 2 years, mean platelet count of the patients was 210.000 (175.000-265.000) microL. CONCLUSION: In adult cases who do not respond to surgical and medical therapy, including splenectomy, the results obtained from the therapy using the method of Immunoadsorption with Immunoglobulin Adsopak are promising both in short and long-term follow up.

Relationship Between Serum Macrophage Migration Inhibitory Factor Level and Insulin Resistance, High-Sensitivity C-Reactive Protein and Visceral Fat Mass in Prediabetes.

BACKGROUND: Growing evidence suggest that macrophage migration inhibitory factor (MIF) plays a vital role in glucose metabolism. We aimed to ascertain whether MIF levels are altered in subjects with prediabetes and also to determine the relationship between MIF and metabolic parameters as well as visceral fat mass. MATERIAL AND METHODS: This cross-sectional study included 40 subjects with prediabetes and 40 age-, body mass index (BMI)- and sex-matched subjects with normal glucose tolerance. Circulating MIF levels were measured using enzyme-linked immunosorbent assay. Metabolic parameters of recruited subjects were evaluated. Visceral fat mass was measured using bioelectrical impedance method. RESULTS: Circulating MIF levels were found to be elevated in subjects with prediabetes compared to controls (26.46 ± 16.98 versus 17.44 ± 11.80 ng/mL, P = 0.007). MIF positively correlated with BMI, visceral fat mass and indirect indices of homeostasis model assessment of insulin resistance. In linear regression model, an independent association was found between MIF levels and metabolic parameters, including BMI, visceral fat mass and homeostasis model assessment of insulin resistance. Multivariate logistic regression analyses revealed that the odds ratio for prediabetes was higher in subjects in the highest quartile of MIF compared to those in the lowest quartile, after adjusting for potential confounders. CONCLUSIONS: Increased MIF levels are associated with the elevation of prediabetic risk.

Relationship between insulin resistance, hs-CRP, and body fat and serum osteoprotegerin/RANKL in prediabetic patients.

BACKGROUND: Receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPN) are soluble members of the tumor necrosis factor superfamily. Growing evidence suggest that there is link between inflammation, insulin resistance and OPG, soluble RANKL (sRANKL). We aimed to ascertain whether OPG and sRANKL levels are altered in prediabetic subjects and there is association between OPG/sRANKL and metabolic parameters. METHODS: Forty prediabetic subjects and 40 age- and BMI-matched controls were recruited for this cross-sectional study. Circulating OPG, sRANKL were measured using ELISA. Anthropometric and metabolic parameters were also determined. RESULTS: Circulating sRANKL (97.74±17.67 vs. 55.00±11.19 pg/mL, P=0.010) and OPG (261.54±74.55 vs. 159.23±52.91 pg/mL, P=0.020) levels were found to be significantly higher in diabetic subjects compared with control subjects. There was a positive correlation between sRANKL and OPG. sRANKL also positively correlated with BMI, insulin resistance marker HOMA-IR, inflammatory marker hs-CRP. Logistic regression analyses revealed that the odds ratio was increased for prediabetes in subjects with having elevated sRANKL levels. CONCLUSIONS: Increased sRANKL and OPG levels were associated with prediabetic subjects. sRANKL and OPG may play a role in the pathogenesis of diabetes as well as metabolic disturbance.

Close monitoring of these parameters and early intervention in alterations are of vital importance.

Comparison of pre- and post-levothyroxine high-sensitivity c-reactive protein and fetuin-a levels in subclinical hypothyroidism.

OBJECTIVE: The objective of this trial was to determine the levels of inflammatory markers, high-sensitivity C-reactive protein and fetuin-A pre- and post-levothyroxine treatment in cases of subclinical hypothyroidism. MATERIALS AND METHODS: A total of 32 patients with a diagnosis of subclinical hypothyroidism and a control group of 30 healthy individuals were tested for high-sensitivity C-reactive protein and fetuin-A, followed by the administration of 50 µg of levothyroxine in the patient group for 3 months. During the post-treatment stage, high-sensitivity C-reactive protein and fetuin-A levels in the patient group were re-assessed and compared with pre-treatment values. RESULTS: Pre-treatment levels of both high-sensitivity C-reactive protein and fetuin-A were observed to be higher in the patient group than in the control group. The decrease in high-sensitivity C-reactive protein levels during the post-treatment stage was not statistically significant. However, the decrease observed in post-treatment fetuin-A levels was found to be statistically significant. CONCLUSION: The decrease in fetuin-A levels in subclinical hypothyroidism cases indicates that levothyroxine treatment exerts anti-inflammatory and anti-apoptotic effects. Although the decrease in high-sensitivity C-reactive protein levels was statistically non-significant, it is predicted to reach significance with sustained treatment.

Increased circulating macrophage migration inhibitory factor levels are associated with coronary artery disease.

BACKGROUND: To evaluate the macrophage migration inhibitory factor and E-selectin levels in patients with acute coronary syndrome. MATERIALS/METHODS: We examined the plasma migration inhibitory factor and E-selectin levels in 87 patients who presented with chest pain at our hospital. The patients were classified into two groups according to their cardiac status. Sixty-five patients had acute myocardial infarction, and 22 patients had non-cardiac chest pain (non-coronary disease). We designated the latter group of patients as the control group. The patients who presented with acute myocardial infarction were further divided into two subgroups: ST-elevated myocardial infarction (n = 30) and non-ST elevated myocardial infarction (n = 35). RESULTS: We found higher plasma migration inhibitory factor levels in both acute myocardial infarction subgroups than in the control group. However, the E-selectin levels were similar between the acute myocardial infarction and control patients. In addition, we did not find a significant difference in the plasma migration inhibitory factor levels between the ST elevated myocardial infarction and NST-elevated myocardial infarction subgroups. DISCUSSION: The circulating concentrations of migration inhibitory factor were significantly increased in acute myocardial infarction patients, whereas the soluble E-selectin levels were similar between acute myocardial infarction patients and control subjects. Our results suggest that migration inhibitory factor may play a role in the atherosclerotic process.
