Fatigue in newly diagnosed acute myeloid leukaemia: general population comparison and predictive factors

Objectives: This study compared the burden of fatigue between treatment-naïve patients with newly diagnosed acute myeloid leukaemia (AML) and the general population and investigated patient factors associated with fatigue severity. Methods: Pretreatment patient-reported fatigue was assessed with the Functional Assessment of Chronic Illness Therapy-Fatigue questionnaire in a sample of 463 newly diagnosed patients with AML who were enrolled in a clinical trial. Multivariable linear regression models were used to estimate the adjusted mean differences in fatigue between patients with AML and adults from the general population (n=847) by AML disease risk categories. A clinically meaningful difference in fatigue was defined as ≥3 points. Univariable and multivariable linear regression models were used to identify sociodemographic, clinical and molecular correlates of worse fatigue in patients with AML. Results: Patients with AML reported adjusted mean fatigue scores that were 7.5 points worse than the general population (95% CI -8.6 to -6.4, p<0.001). Across AML disease risk categories, adjusted mean differences in fatigue compared with the general population ranged from 6.7 points worse (patients with favourable risk: 95% CI -8.6 to -4.8, p<0.001) to 8.9 points worse (patients with poor risk, 95% CI -10.5 to -7.2, p<0.001). Overall, 91% of patients with AML reported fatigue that was equal to or worse than the general population's median fatigue score. Higher pretreatment fatigue was independently associated with female sex, WHO performance status ≥1 and lower platelet levels. Conclusions: Patients with newly diagnosed AML reported worse fatigue than the general population, and mean differences exceeded twice the threshold for clinical significance. Our findings may help to identify patients with AML most likely to benefit from supportive care interventions to reduce fatigu

Life-Threatening Autoimmune Hemolytic Anemia and Idhiopatic Thrombocytopenic Purpura. Successful Selective Splenic Artery Embolization

Selective splenic artery embolization (SSAE) is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a case of a patient affected by idiopathic thrombocytopenic purpura (ITP) and warm auto-immune hemolytic anemia (AIHA) both resistant to immunosuppressive and biological therapies, not eligible for a surgical intervention because of her critical conditions. She underwent SSAE and achieved a hematologic complete response within a few days without complications. SSAE is a minimally invasive procedure to date not considered a standard option in the management of AIHA and ITP. However, following the progressive improvement of the techniques, its indications have been extended, with a reduction in morbidity and mortality compared to splenectomy in patients with critical clinical conditions. SSAE was a lifesaving therapeutic approach for our patient and it may represent a real alternative for the treatment of resistant AIHA and ITP patients not eligible for splenectomy

Prospective Cytomegalovirus Monitoring During First-Line Chemotherapy in Patients With Acute Myeloid Leukemia

Little is known about the incidence and clinical impact of cytomegalovirus (CMV) infection in patients with acute myeloid leukemia at the time of diagnosis and during chemotherapy. The aims of the present study were to assess prospectively the incidence of active CMV infection in 69 consecutive patients with acute myeloid leukemia and to describe the outcomes of treatment. pp65 antigenemia was monitored at diagnosis, post-induction and post-consolidation chemotherapy, and whenever CMV reactivation was suspected. Patients with pp65 antigenemia received pre-emptive anti-CMV treatment. Fifty-nine patients achieved complete remission. Baseline CMV serology results were available for 56 of the 59 patients: 52 patients (93%) were IgG positive. The overall incidence of pp65 antigenemia in patients in complete remission after chemotherapy was 35% (21/59): 9 patients after induction and 12 post-consolidation. Sixteen of the 21 pp65-positive patients received anti-CMV treatment: 15 as pre-emptive therapy and 1 for interstitial CMV pneumonitis. Five patients received no anti-CMV treatment and did not develop CMV disease. Patients with pp65 antigenemia had more hospital admissions (2.57 vs. 2.16; P=0.009), while patients with >10 pp65-positive cells had more clinical complications (8/9 vs. 2/12; P=0.002). In conclusion, patients with acute myeloid leukemia receiving chemotherapy should be monitored for active CMV infection. CMV reactivation in these patients was associated with an increased number of hospital admissions, and high levels of pp65 antigenemia were associated with more clinical complications. Controlled studies are needed to assess the relevance of pre-emptive anti-CMV therapy in patients with acute myeloid leukemia receiving chemotherapy. J. Med. Virol. 82:1201-1207, 2010.

Thrombotic thrombocytopenic purpura during pregnancy versus imitator of preeclampsia.

BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is a severe disorder affecting the microcirculation of multiple organs due to a systemic endothelial cell injury secondary to a deficiency in ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 motif, member 13) activity. TTP is a rare complication of pregnancy with a poor prognosis and high fetal mortality, especially when it occurs during the first trimester. Recent data have supported that effective treatment of TTP is plasma therapy. Unfortunately a major problem remains in the delay in diagnosis due to confounding factors between other "imitators of preeclampsia." Rapid and readily available laboratory testing to quickly diagnose TTP is desperately needed to improve care and to save mother and future child life. CASE REPORT We describe a rare case of successful pregnancy after TTP manifestations occurring in the first trimester; most importantly, our experience represents the first case of atypical manifestation due to neurologic and kidney manifestations preceding laboratory assay alterations. RESULTS We treated a patient with plasma replacement of 30 mL/kg/day and daily plasmapheresis in combination with continuous infusion of fresh-frozen plasma 10 mL/kg/day. The response of clinical manifestation immediately improved. At 30 weeks, the patient had multiple episodes of high blood pressure and concomitant decrease of hemoglobin and platelet count, so a cesarean section was immediately performed. She delivered a healthy female baby. CONCLUSION Early diagnosis by ADAMTS13 activity, occasionally occurring before clinical manifestations, aided us in promptly administering commended and life-saving treatments
