The effect of budesonide mouthwash on oral chronic graft versus host disease.

Oral chronic graft versus host disease (cGVHD) is common and a major cause of morbidity and loss of quality of life in long term survivors. Cyclosporine with prednisone remains the first line therapy for oral manifestations of cGVHD. However, even with routine administration of systemic agents, many patients with oral manifestations of cGVHD do not have resolution of their disease and may benefit from incorporation of local therapy. Budesonide is a highly potent steroid which has minimal systemic side effects and being used for oral cGVHD. We designed a retrospective study to compare treatment results of patients with oral cGVHD who received topical budesonide in addition to systemic therapy that consists of combined prednisone and cyclosporine (Group A, n = 12), with the treatment results of patients who were administered the same systemic therapy alone (Group B, n = 11) to determine whether budesonide mouthwash had any advantage on response rates. Three mg topical budesonide/10 ml saline was used 3-4 times a day for up to 6 months in group A. Diagnosis, clinical staging, and treatment response scoring for cGVHD were performed according to National Institutes of Health (NIH) consensus criteria. At the baseline examination, there were no statistically significant differences in terms of median oral cGVHD examination scores between two groups. After treatment, there was statistically significant decrease in median oral cGVHD examination scores compared to baseline (P < 0.001 and 0.021), and significant differences were found between two groups (P < 0.032). Overall response rate was 83% and 36% for group A and B, respectively (P = 0.036). However, no statistically significant differences were found between median pain scores of two groups before and after treatment (P = 0.740 and P = 0.091). No major systemic side effects and oral candidiasis were observed in two groups of patients. We concluded that topical budesonide might be added to systemic therapy to obtain better response rates in patients with oral cGHVD.

Kikuchi-Fujimoto disease: a rare but important cause of fever and lymphadenopathy in pregnant women.

We report a case of Kikuchi-Fujimoto disease (KFD) in a 28-year-old pregnant woman with prolonged fever and generalized lymphadenopathy. We evaluated the patient for etiology of the fever and adenopathy, which were unresponsive to antibiotic therapy. Cervical lymph node histology showed KFD. Currently, there is scant data available regarding the course and treatment of KFD during pregnancy. We administered steroid therapy (prednisone 1 mg/kg/day) to control severe systemic and constitutional symptoms. We observed a reduction in lymph node size as well as abatement of fever and other constitutional symptoms. The patient carried the fetus to full term with no apparent adverse effect. Our experience showed that steroid therapy may be used effectively to control KFD-related symptoms after the first 16 weeks without terminating the pregnancy.

Prognostic significance of Fas (CD95/APO-1) positivity in patients with primary nodal diffuse large B-cell lymphoma.

Fas (CD95/APO-1) is a protein that is mainly related to apoptosis of lymphoid cells. The increment of Fas expression is associated with long-term survival in various malignancies. However, there are limited studies regarding the effect of Fas expression on the course and prognosis of non-Hodgkin's lymphoma. The aim of this study was to investigate the significance of immunohistochemical Fas expression on the prognosis of nodal diffuse large B-cell lymphoma. A total of 63 patients with primary nodal diffuse large B-cell lymphoma diagnosed in the Erciyes University Department of Hematology between 1990 and 2003 were included in the study. The median age of the patients was 55 years old (range 19-102 years old). The median follow-up period was 19 months (2-132 months). Histopathological sections were stained immunohistochemically and evaluated by light microscopy for Fas, bcl-2, and p53. Clinical and laboratory parameters including Fas, bcl-2, and p53 positivity, age, sex, performance status, clinical stage, presence of B symptoms, bone marrow involvement, extranodal involvement, and lactic dehydrogenase levels were evaluated to compare overall survival. Complete remission was obtained in 28 patients (44.4%) after first-line chemotherapy. Fas positivity, male gender, good performance status, clinical stage I-II, absence of B symptoms, normal lactic dehydrogenase value, and absence of bone marrow involvement were favorable prognostic factors for complete remission in statistical analysis. Multivariate analysis revealed that positive Fas expression and ECOG performance status were independent prognostic factors for overall survival. Also, Fas-positive patients had significantly prolonged progression-free survival. Immunohistochemical Fas positivity was a favorable prognostic factor for complete remission and overall and progression-free survival in primary nodal diffuse large B-cell lymphoma.

Anti-tumor necrosis factor-alpha-induced psoriasis.

We describe a patient with rheumatoid arthritis who developed psoriasis during treatment with etanercept; psoriatic lesions resolved completely after the drug was discontinued, but returned on rechallenge. No such adverse skin reaction occurred after switching therapy to infliximab. Through a Medline search we identified 11 reports involving 32 patients who developed psoriasis/psoriasiform eruptions during therapy with tumor necrosis factor-alpha (TNF-alpha) inhibitors. All TNF-alpha blocking agents have been reported to lead to or exacerbate psoriasis. In some cases skin changes were severe enough to discontinue the medication.

Localized gastric amyloidosis: a case report.

Local deposition of amyloid without systemic involvement is rather uncommon and has been found in many organs. A 67-year- old man was admitted to our hospital presenting with weight loss, fatigue and poor appetite. Blood work and bone marrow examination revealed megaloblastic anemia. Upper gastrointestinal endoscopy reveeled e purple polypoid wass lesion of 5mm eliameter in the paracardiac region. Histopathologic examination of the gastric biopsy showed the deposition of amyloid materials in the mucosa. The patient had no evidence suggesting systemic amyloidosis. We report a rare case of localized amyloidosis of the stomach. The clinical and pathological features of this rare condition and association with megaloblastic anemia are discussed.

Intravenous gamma globulin is effective as an urgent treatment in Brucella-induced severe thrombocytopenic purpura.

Severe thrombocytopenia is a rare hematologic manifestation of brucellosis, which can occasionally be associated with bleeding into the skin and from mucosal sites. Prompt recognition of this brucellosis complication and aggressive therapy is vital because the mortality rate associated with bleeding into the central nervous system is high. We report a case of a patient infected with Brucella melitensis who was admitted with a severe case of thrombocytopenic purpura. The patient responded well to intravenous gamma globulin (IVIg) treatment with platelet recovery within 2-3 days. For cases of Brucella-induced thrombocytopenic purpura, IVIg may be administered as an urgent therapy until the microbial therapy takes effect.

Overexpression of cyclooxygenase-2 in multiple myeloma: association with reduced survival.

Cyclooxygenases (COX) are key enzymes in the conversion of arachidonic acid to prostaglandins. Several studies have shown a relation between angiogenesis and COX-2 expression. Elevated expression of cyclooxygenase-2 (COX-2), however, has not been reported in multiple myeloma (MM) in the literature. The aim of this study is to investigate COX-2 expression in MM as well as its correlation with prognostic factors and estimated survival rates. Immunohistochemical staining of the paraffin-embedded bone marrow biopsy tissues (n = 51) was performed using isoform-specific COX-2 polyclonal antisera (Santa Cruz Biotechnology, Santa Cruz, CA). Results were correlated with recognized clinical parameters, which were retrospectively obtained from patients' files. There were 15, 19, and 17 bone marrow biopsy specimens with negative, weak-moderate, and strong COX-2 immunostaining, respectively. According to univariate analysis, beta2-microglobulin, age, stage, COX-2 expression, and serum lactate dehydrogenase levels were significant prognostic factors for survival in patients with multiple myeloma. COX-2 expression, age, and serum lactate dehydrogenase levels (greater than 1x normal level) were significant prognostic factors by multivariate analysis. Kaplan-Meier overall survival estimate of those patients with negative or weak-moderate COX-2 immunoreactivity in myeloma cells was significantly better than that of patients with strong COX-2 immunoreactivity (log-rank chi(2) = 21,43, P < 0.001). COX-2 overexpression was associated with reduced estimated survival. Poor prognostic factors such as LDH, age, and beta2-microglobulin were also correlated with COX-2 expression. Potent, specific COX-2 inhibitors showing evident antiangiogenic and antitumor effects on cancers could provide new therapeutic strategies in the treatment of MM.

Acute trichinellosis in children compared with adults.

OBJECTIVES: Trichinellosis is a cosmopolitan parasite infection caused by Trichinella nematodes that is acquired from consumption of raw meat from several animal species. Knowledge of the clinical pattern and laboratory features of the disease in childhood is limited. The purpose is to study the clinical pattern of trichinellosis caused by Trichinella britovi in children and to compare it in household adults. METHODS: We evaluated all children up to 17 years of age and their adult householders exposed to the consumption of infected meat during an outbreak of trichinellosis. A questionnaire was developed to record clinical data. The blood sample was collected for blood count, muscle enzymes, serum electrolytes, albumin and serology. All exposed children were treated with mebendazole, and severe symptomatic patients received prednisolone. Clinical and laboratory presentations and outcome were recorded. To evaluate the clinical picture of trichinellosis in childhood, clinical and laboratory findings were compared between children and household adults with a confirmed diagnosis who consumed the same amount of infected meat. RESULTS: In 47 (62%) of 76 children with suspected trichinellosis, the diagnosis was serologically confirmed. The main clinical and laboratory findings in children were fever, abdominal pain, myalgia, facial and/or eyelid edema, rash, eosinophilia and increased muscular enzymes. The incubation period was similar in children and adults, but myalgia (66% versus 96%, P < 0.01), facial and/or eyelid edema (57% versus 86%, P < 0.05), eosinophilia (52% versus 96%, P < 0.01) and increased serum creatine kinase (38% versus 79%, P < 0.01) were less common in children than in adults. Seroconversion occurred in fewer children than adults, but the difference was not statistically significant. CONCLUSIONS: T. britovi infection shows a benign course and a milder clinical picture in children than in adults who consumed the same amount of infected meat.

Severe thrombotic microangiopathy associated with brucellosis: successful treatment with plasmapheresis.

Brucellosis is a disease that may lead to changes in hematologic parameters such as anemia, neutropenia, and thrombocytopenia; however, thrombotic microangiopathy (TMA) is a rare finding. Severe TMA may be associated with life-threatening hematologic, renal, and neurologic disorders. To prevent this mortality caused by brucellosis, prompt recognition of this complication and prompt therapy are essential. A patient with TMA associated with Brucella melitensis is presented who initially presented with fever, skin purpura, epistaxis, confusion, microangiopathic hemolytic anemia, and thrombocytopenia. TMA was treated with plasmapheresis with cryosupernatant plasma replacement, energetically. A rapid improvement in platelet count, lactate dehydrogenase level, hemolytic anemia, and neurologic symptoms was observed with this treatment. For cases with infection-induced thrombotic microangiopathy, short-term plasmapheresis may be applied as an urgent therapy in addition to antimicrobial therapy.

The role of plasma exchange in HELLP syndrome.

Plasma exchange therapy has been successfully used in selected patients with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome who have organ failure or refractory to treatment. There is no prospective study regarding plasma exchange and its effect in HELLP syndrome. The aim of this study was to investigate the effects of early postpartum use of plasma exchange in patients with HELLP syndrome on outcomes. The mortality rate and the recovery times were compared in patients with HELLP syndrome treated with plasma exchange and historic control group of patients treated conservatively. During a 3-year period (between April 2000 and December 2003), 29 consecutive patients with HELLP syndrome were treated with single or multiple plasma exchange by using fresh-frozen plasma at post-partum period. The control group consist of 26 patients with HELLP syndrome treated between 1993 and 1999. Maternal mortality rate was 23.1% in the control group; there was no death in plasma exchange group; and the mortality rate was significantly higher in the control group (p=0.006). The length of stay at the intensive care unit was shorter in the plasma exchange group (p<0.0001). Rapid improvement of the platelet, aspartate aminotransferase, alanine aminotransferase, and lactic dehydrogenase levels were observed in the plasma exchange group. This study showed that postpartum early plasma exchange therapy improves treatment outcomes in patients with severe HELLP syndrome.

Thyrotoxic periodic paralysis in a Turkish male; the recurrence of the attack after radioiodine treatment.

Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare complication of hyperthyroidism and an uncommon form of hypokalemic periodic paralysis. Its differentiation of more common forms of periodic paralysis is important because aggressive treatment can place the patient at risk for rebound hyperkalemia. Treatment of the underlying thyroid dysfunction cures the muscle symptoms. Here we describe a 37-year-old Turkish male with THPP whose paralysis attack recurred soon after administration of radioactive iodine.

Thrombosis and priapism in a patient with Henoch-Schonlein purpura.

Henoch-Schönlein purpura (HSP) belongs to the category of systemic small-vessel vasculitis. Although long-term outcome is generally good, serious complications may occur. Thrombosis and priapism have been reported only as extremely rare complications of HSP. We describe a 37-year-old man who developed recurrent thrombotic events shortly after he had been diagnosed as having HSP. Although he had additional risk factors for thrombosis, such as prothrombin G20210A mutation and use of celecoxib before the last episode, temporal relation of the thrombotic attacks to the onset of HSP suggest that the disease itself may lead to a prothrombotic state. This case is the first adult HSP patient with priapism, which probably developed secondary to thrombosis of the dorsal penile vein.

The effects of fresh frozen plasma on cholinesterase levels and outcomes in patients with organophosphate poisoning.

OBJECTIVE: The aim of this study is to determine the effects of fresh frozen plasma, as a source of cholinesterase, on butyrylcholinesterase (BuChE; plasma or pseudo cholinesterase) levels and outcomes in patients with organophosphate poisoning. MATERIALS AND METHODS: This prospective study was performed at the Department of Intensive Care of Erciyes University Medical School. Over 2 yrs, patients admitted to the ICU for OP poisoning were entered into the study. OP poisoning was diagnosed on the basis of history and BuChE levels. All patients received atropine. Fresh frozen plasma was given to 12 patients. The study was approved by the Ethical Committee, and verbal informed consent was obtained. RESULTS: Thirty-three patients were included in the study. BuChE levels measured at admission and the pralidoxime and atropine doses administered were not different between groups (p>0.05). Although intermediate syndrome developed in 28.6% of patients receiving pralidoxime, there were no intermediate syndrome cases in patients receiving plasma prior to developing intermediate syndrome. The mortality rates were 14.3% in the pralidoxime group and 0% in the plasma+atropine+pralidoxime group. Two patients received plasma after developing the intermediate syndrome, and one patient who received only atropine died. BuChE levels of fresh frozen plasma were 4069.5 +/- 565.1 IU/L. Every two bags of plasma provided an increase in BuChE levels of approximately 461.7 +/- 142.1 IU/L. CONCLUSION: Fresh frozen plasma therapy increases BuChE levels in patients with organophosphate poisonings. The administration of plasma may also prevent the development of intermediate syndrome and related mortality. Plasma (fresh frozen or freshly prepared) therapy may be used as an alternative or adjunctive treatment method in patients with organophosphate pesticide poisoning, especially in cases not given pralidoxime. Further randomized controlled and animal studies are required to infer a definitive result.

Plasma levels of free tissue factor pathway inhibitor in patients with various thyroid disorders.

Various coagulation abnormalities occur in thyroid disorders and its range may vary from subclinical laboratory abnormalities to clinically significant disorders of coagulation. Tissue factor pathway inhibitor (TFPI), which inhibits the initial reaction of tissue factor mediated coagulation pathway, is reported to be increased in patients with Graves disease (GD) in one study. Hyperthyroid (n=10), hypothyroid (n=10) and subclinical hypothyroid (n=10) patients and control cases (n=16) were evaluated for free and total tissue factor pathway inhibitor (tTFPI), plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (tPA) levels in disease and euthyroid states. Free TFPI levels were significantly higher in hyperthyroid patients compared with the control group and subclinic hypothyroid patients (p<0.001), but not with hypothyroid patients (p>0.05). After the euthyroid state was obtained in the hyperthyroid group, the levels of total TFPI (p<0.05), free TFPI (fTFPI) (p<0.005), t-PA (p<0.005) and PAI-1 (p<0.02) decreased significantly. In hyperthyroid patients, there was a strong correlation between thyroid functions and free TFPI levels. In conclusion, we hypothesize that coagulation abnormalities seen in thyroid disorders cannot be explained directly with the impaired fibrinolytic activity but also with the elevated fTFPI levels. Both increased plasma fTFPI and PAI-1 levels could be markers of the peripheral activity of thyroid hormones.
