Evaluation of oral manifestations and head and neck lymphadenopathy in newly diagnosed acute leukemia patients

OBJECTIVES

To determine the frequency of head and neck lymphadenopathy (LAP) and intraoral findings (non-dental/dental) in patients with newly diagnosed acute leukemia (AL).

SUBJECTS AND METHODS

Twenty-eight (52.8%) females and 25 (47.2%) males in a total of 53 patients with newly diagnosed AL with a mean age of 46 years were included in the study. Personal information, the type of AL (AML [acute myelogenous leukemia]/ALL [acute lymphocytic leukemia]), and hematological findings (anemia, neutropenia, and thrombocytopenia) were obtained from medical records. One of two calibrated oral diagnosis and maxillofacial radiology specialists performed extraoral (head and neck LAPs) and intraoral (non-dental and dental) clinical examinations. The Chi-square (χ2) test was used to evaluate categorical variables.

RESULTS

LAP was observed in 22.6% and intraoral findings in 30.2% of the patients. LAP was most commonly observed in the neck and none in the parotid glands. The most intraoral findings were gingival/mucosal bleeding and oral petechiae/ecchymosis. While there was no statistical difference between AML and ALL patients in terms of LAP (p > .05), intraoral findings were observed more in patients with AML (p < .05). Only two (3.8%) patients had dental findings. With a slight difference, intraoral findings were more with thrombocytopenia and LAP with neutropenia.

CONCLUSION

In AL, especially non-dental intraoral findings are common. The fact that dentists working in the oral cavity are often the first specialists to encounter the oral manifestations of AL imposes an important role in early diagnosis and treatment.

Efficiency of intravenous iron carboxymaltose in patients with iron-deficiency anemia due to heavy menstrual bleeding: a single-center experience

OBJECTIVE

Heavy menstrual bleeding (HMB) is the most common cause of iron deficiency anemia (IDA) in premenopausal women. Clinical studies have shown that iron carboxymaltose (ICM) is an appropriate, effective, and well-tolerated treatment option for clinical situations associated with iron deficiency (ID).

PATIENTS AND METHODS

This study took 78 out of 400 consecutive patients diagnosed with IDA due to HMB and intolerant or insufficient response of oral iron. All patients were administered the total calculated dose of ICM separately, based on the body weight and current hemoglobin (Hb) level. All the anemia parameters of the patients were compared before and after treatment.

RESULTS

All anemia parameters, including median Hb, ferritin, and transferrin saturation, significantly increased four weeks after treatment. Pre- and post-treatment mean Hb levels were 8.9 (± 1.7) g/dL and 12.3 (± 1.2) g/dL, respectively. The mean ferritin level of the patients before treatment was 3.93 (± 2.7) ng/mL. After treatment, the mean ferritin level was 244 (± 185) ng/mL. The mean transferrin saturation levels before and after treatment were 5.7% (± 5.0) and 43.1% (± 20.9), respectively. Although no serious side effects were observed in all patients, headache was detected in 2 patients (2.6%), urticaria in 3 patients (3.8%), and flushing in 2 patients (2.6%).

CONCLUSIONS

ICM is an effective and safe treatment option for patients with IDA due to HMB, in which oral iron therapy is insufficient or intolerant. In fact, without waiting for the failure or intolerance of oral iron therapy, moving ICM to the frontline could be cost-effective and more convenient to patients with HMB and health care providers.

Skin ulcers caused by ruxolitinib in a patient with chronic cutaneous graft-versus-host disease

INTRODUCTION

Graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic cell transplantation (HCT). In the treatment of chronic GVHD, skin directed therapy, systemic corticosteroids, calcineurin inhibitors (such as cyclosporine (CsA) and tacrolimus), rituximab, mycophenolate mofetil (MMF), extracorporeal photopheresis (ECP) and ruxolitinib are used.

CASE REPORT

We present an 18 year old male with Philadelphia chromosome positive acute B lymphoblastic leukemia, treated with allogeneic HCT from a full matched sibling donor. The patient had grade 2 chronic cutaneous GVHD resistant to corticosteroids, CsA, MMF, and ECP treatment. Three months after initiation of ruxolitinib therapy, the patient developed skin ulcers on his lower extremities.

MANAGEMENT & OUTCOME

The biopsy revealed that the changes were caused by the drug reactions. We suspected ruxolitinib as the likely cause of these ulcerative lesions after evaluating the adverse drug reaction probability scale. The adverse drug score was 4, therefore, ruxolitinib treatment was discontinued. Ulcerative lesions fully recovered after 4 weeks of follow-up.

DISCUSSION

Ruxolitinib is used in the treatment of chronic GVHD that has been resistant to steroids and other salvage therapies. In our case, ruxolitinib was used as a salvage therapy in a patient who had refractory chronic skin GVHD. Ruxolitinib-related skin lesions with ulcers of lower extremities and whole body erythematous skin lesions were reported previously in patients with myelofibrosis. The pathophysiology of ruxolitinib related skin ulcers is unknown. Skin changes of patients using ruxolitinib should be closely monitored, and newly developing lesions should be suspected of being drug-related and biopsied.

Non hemorrhagic pericardial effusion from ibrutinib İn a patient without comorbidities

INTRODUCTION

The most common kind of leukemia in adults is chronic lymphocytic leukemia (CLL). CLL is treated with ibrutinib. During the course of ibrutinib therapy, bleeding and cardiac arrhythmias may occur. Non-hemorrhagic adverse events are extremely infrequent in individuals using ibrutinib.

CASE REPORT

A 64 year-old man was diagnosed with CLL in June 2016. He was treated with 6 courses of FCR, he stayed in remission for 3 years and then relapsed. He achieved partial remission after two months of therapy with ibrutinib. The patient was admitted to the hospital with fever and shortness of breath. Pericardial tamponade and effusion was diagnosed during his evaluation.

MANAGEMENT & OUTCOME

Non-hemorrhagic exudative effusion was drained by pericardiocentesis and a pericardial catheter was inserted to drain pericardial effusion. In all pleural and pericardial effusion samples, pathological and flow cytometric examination revealed no atypical malignant cells for malignancy, including CLL. Infections, both bacterial and viral, were also undetectable in the samples, as were rheumatological markers of collagen vascular disease. Ibrutinib therapy was discontinued. The pericardial effusion and tamponade were linked to ibrutinib treatment after evaluating the adverse drug reaction probability scale with a total score of 6. Colchicine was administered to reduce the pericardial effusion. The catheter was removed; pericardial effusion did not reoccur during follow up visits.

DISCUSSION

Serious adverse events of ibrutinib are seen when treating CLL patients. This group of individuals should be closely monitored for potentially serious complications such as pericardial effusion and cardiac tamponade.

Is increased red cell distribution width an indicating marker of nonalcoholic steatohepatitis and fibrotic stage?

AIM: To evaluate the red cell distribution width (RDW) as an indicator of the presence of non-alcoholic steatohepatitis (NASH) and its association with fibrotic scores.

METHODS: A retrospective study was carried out that included sixty-two biopsy proven NASH, 32 simple steatosis patients and 30 healthy controls. The correlation between the clinical and histopathological features of NASH patients and RDW values was evaluated. Liver fibrosis scores were measured using a 0 to 4 point scale and were divided in to two groups; fibrosis scores 0-1 were termed mild and fibrosis scores 2-4 were termed advanced fibrosis. RDW values were compared between NASH, simple steatosis and healthy controls. Univariate and multivariate analyses were performed to evaluate the independent predicting factors for the presence of liver fibrosis caused by NASH.

RESULTS: Patients with NASH had higher RDW values compared with simple steatosis and healthy control groups [14.28% ± 0.25% vs 13.37% ± 0.12%, 12.96% ± 0.14% (P < 0.01), respectively]. Patients with advanced fibrosis had higher RDW values than the mild fibrosis group (15.86% ± 0.4% vs 13.63% ± 0.67%, P < 0.01, respectively). RDW also correlated with fibrotic scores (r = 0.579 and P < 0.01). The variables that were significant in the univariate analysis were evaluated in multivariate logistic regression analysis, and RDW was an independent predicting factor of NASH (OR = 1.75, 95%CI: 1.129-2.711, P < 0.05).

CONCLUSION: RDW a new non-invasive marker that can be used to demonstrate the presence of NASH and indicate advanced fibrotic scores.
