RESUMO

Immune thrombocytopenia (ITP) is a rare autoimmune disorder presenting with isolated thrombocytopenia. Splenectomy is still one of the treatment alternatives for these patients. Here we aim to analyze long term follow-up data of splenectomy in immune thrombocytopenia. This retrospectively designed study was conducted in a tertiary health clinic. Patients with ITP who were splenectomized between 1990 and 2015 were included. Response to treatment was interpreted as 'complete response', 'response' or 'no response'. The incidence of response loss was evaluated. Perioperative and long term complications and overall survival rates were determined. Out of 51 patients, who underwent splenectomy after 12 months of diagnosis, 47 achieved a response (92.2%). Of 47 patients who had a platelet count at least 30.000/µL, 41 (87.2%) had CR. Incidence of loss of response was 10.5% (95% confidence interval (CI): 4%-26.1%) at 30 months. Two patients died, and overall survival rate was 97.4% (95% CI: 82.8%-99.6%) at 30 months of follow up. Considering the complications: two patients had venous thromboembolism, 11 had minor bleeding episodes and 15 suffered from perioperative infections. Our study suggests that splenectomy promises a high level of response with acceptable complication rates. Although less preferred recently, splenectomy should still be taken into consideration when remission is not achieved especially after 12 months of disease.

RESUMO

PURPOSE: Primary ocular adnexal lymphomas are cured by radiotherapy; however, complications are frequent and relapses may occur. In this case, we aimed to report the efficacy and safety of extended systemic rituximab (anti-CD 20 monoclonal antibody) therapy of conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma. METHODS: In the standard regimen, rituximab is used as four consecutive weekly infusions of 375 mg/m2 in patients with low-grade lymphomas. We treated a patient who had bilateral conjunctival MALT lymphoma with rituximab 375 mg/m2 intravenously once weekly for 10 weeks as a first-line therapy. RESULTS: During the examination of the sixth week, we observed partial response of the lesions in both eyes. At the end of the tenth cure, complete remission was achieved. No local or systemic adverse effect was observed. The patient has no signs of recurrence during the 22-months follow-up period. CONCLUSION: Extended rituximab therapy may be an effective and well-tolerated first-line treatment option for bilateral conjunctival MALT lymphoma.

RESUMO

BACKGROUND: The prognostic significance of complete cytogenetic response (CCyR) is well defined in patients with chronic phase chronic myeloid leukemia treated with imatinib as first-line therapy. However, the effect on outcomes of obtaining molecular response itself and the depth of it is not clear. In this study we aimed to determine the frequency of complete molecular response (CMR) during long-term follow-up and the clinical significance of CMR on patient outcomes and survival. PATIENTS AND METHODS: We retrospectively evaluated the files of 178 chronic phase chronic myeloid leukemia patients using imatinib therapy. Forty-seven patients with missing data were excluded from the study and the assessment was done in 131 patients. CMR was defined as undetectable BCR-ABL transcripts using real-time quantitative polymerase chain reaction with a sensitivity level of ≥ 104 in 2 consecutive analyses at least 3 months apart. Cytogenetic and molecular monitoring during treatment was performed according to the European LeukemiaNet recommendations criteria. Our primary objective was to analyze the association of deeper molecular response with differences in progression-free survival (PFS). RESULTS: Eighty-eight patients (67%) achieved CMR at any time in a median of 65 months of follow-up. The rate of CMR was higher in patients who achieved CCyR at 12 months and major molecular response (MMR) at 18 months. Fewer events occurred in the CMR group than the MMR group (26.1% vs. 50.0%). Overall survival was not different in both groups. CMR was associated with longer PFS with borderline significance. CONCLUSION: Prolonged imatinib therapy helps to achieve a deeper molecular response in the long-term. Achieving deeper molecular response at any time positively affects maintaining the cytogenetic and molecular responses, and decreases the transformation to accelerated and/or blastic phase. The slight prolongation in PFS did not reach statistical significance.

RESUMO

Eltrombopag was used in patients with chronic primary immune thrombocytopenia (ITP) who did not tolerate or were refractory to two or more previous treatments. The primary aims of the study were to determine the efficacy and safety of long-term eltrombopag treatment. Data were extracted from medical chart records retrospectively. Platelet count of at least 50 000/µl at any time point during the treatment was defined as the 'response'. Median duration of eltrombopag treatment was 29 weeks (11-74). The number of patients who had a platelet count of at least 50 000/µl at any time point was 26 (83.9%). The response was achieved by the second week in most of the patients. Concomitant ITP medications were withdrawn in nine out of the 11 patients. Eltrombopag was discontinued in one patient due to sustained response despite discontinuation of the treatment. Age, sex, concomitant ITP treatments, and previous ITP treatment failures had no impact on the treatment response. The treatment was discontinued due to thrombosis in only four patients. Four patients experienced a minor bleeding event. Hepatotoxicity and all other adverse events were mild and manageable. Eltrombopag is effective, safe, and well tolerated in the long-term treatment of chronic ITP patients.

RESUMO

Hepatobiliary tuberculosis is uncommon even in endemic countries. It is associated with a high mortality and is even diagnosed early in the disease course. Acute liver failure (ALF) caused by tuberculosis bacilli has been reported in only a few reports. All previous cases have been diagnosed by postmortem examination. Time to antituberculosis treatment is very critical. In case of suggestive findings on clinical and radiologic examination, antituberculosis treatment should be initiated immediately. Drug use can be a challenge in patients with ALF. However, as long as the other possible causes of ALF can be excluded and hepatotoxic drugs were avoided during the early course of treatment, such a highly fatal presentation of tuberculosis can be treated safely. Here, we report a case of acute liver failure as a presentation of miliary tuberculosis. He was treated successfully with antituberculosis treatment.

RESUMO

The human JAK2 gene is mainly targeted by two types of genetic lesions that play roles in the pathogenesis of hematologic malignancies: intragenic mutations and chromosomal translocations. Chromosomal translocations of JAK2 are typically associated with myeloid or lymphoid malignancies with an aggressive course and poor outcome. Here we report a t(9;22)(p24;q11.2) translocation, in a MDS patient and review results associated with BCR-JAK2 fusion reported in the literature.

RESUMO

Onychomycosis (OM) is a common fungal infection of the toenails and/or fingernails that is highly prevalent in the general population and also responsible for significant morbidity. OM is caused by dermatophytes, nondermatophytic molds, or yeast. Today systemic antifungal agents are considered as the gold standard for all types of OM. Here we report a case of aplastic anemia associated with oral terbinafine use and a review of the literature on hematological toxicities associated with terbinafine.

RESUMO

BK-virus (BKV) is an important etiological agent for late-onset hemorrhagic cystitis (HC) in patients undergoing hematopoietic stem cell transplantation. Late-onset HC causes significant morbidity among these patients. Therapeutic approaches remain predominantly symptomatic. Several treatment options have been used with variable success rates. Cidofovir has the highest specificity against BKV; however, its lack of availability in the majority of countries, high costs and potential nephrotoxic effects limit its use. The present study reports three cases of severe and prolonged BKV-associated HC (BKHC). HC was resolved in all three of the patients using oral levofloxacin. Thus, levofloxacin may be an effective treatment modality for achieving complete clinical and molecular response in patients with refractory, severe BKHC.

RESUMO

Imatinib mesylate is the standard treatment of chronic myeloid leukemia (CML). Despite imatinib is being used in the treatment of other malignancies as well, its potential role on de novo tumor growth is not known. Secondary malignancies are rarely seen in patients with CML and particularly in those receiving imatinib. Here, we present a CML patient taking imatinib therapy that was diagnosed to have breast cancer and received adjuvant chemo-and radiotherapy with imatinib. We tried to explain co-occurrence of these rare events by probable pathogenetic mechanisms.
