RESUMO

Caspofungin is an echinocandin with proven efficacy in invasive candidiasis (IC) and invasive aspergillosis (IA). This multicenter, prospective, non-comparative, observational ProCAS study was aimed to assess the effectiveness and safety of caspofungin in adult hematological patients with IC or IA under everyday clinical conditions. Favorable outcomes included complete and partial responses on the last day of caspofungin therapy. Safety was assessed up to 14 days post-caspofungin. A total of 115 patients (69 male) with a median age of 52 years (range, 23-78 years) were analyzed. Underlying disease was acute myeloid leukemia in 45 patients (39%), and 21 (18%) were allogeneic stem cell transplant recipients. Thirty-four (29.5%) patients had a diagnosis of IA and 26 (22.6%) had IC (candidemia). The median duration of caspofungin therapy was 14 days (range, 1-100). The overall favorable response rate was 77% (20/26) for patients with IC (69% first-line) and 79% (27/34) for those with IA. Antifungal therapy with caspofungin was generally well tolerated, only two (1.7%) patients having a non-serious drug-related adverse reaction. These results suggest that caspofungin, either alone or in combination, should be considered an effective and safe option for the treatment of invasive mycoses in patients with severe hematological disorders.

RESUMO

Of 167 newly diagnosed acute promyelocytic leukaemia patients, 83 patients were long (L)-form (50%), eight variable (V)-form (5%) and 76 short (S)-form (45%). The V-form and S-form groups presented a significantly higher percentage of patients with white blood cell counts > 10 x 10(9)/l (P < 0.05). The S-form cases displayed a significantly higher number of cases with M3v microgranular features (P = 0.005) and CD34 expression (P < 0.0001). There were no differences between the three isoforms in complete remission (CR) rate (overall CR 90%), but the 3-year disease-free survival was lower for V-form cases than it was for L- and S-form cases (62% vs. 94% and 89%, P = 0.056). We conclude that the V-form and S-form types are associated with some negative prognostic features at diagnosis. However, our data were only able to demonstrate an association with adverse prognosis in the V-form type and, moreover, as the number of cases was limited, needs to be confirmed in large, uniformly treated series.

RESUMO

PURPOSE: To study the relationship between pica and iron-lack anaemia in a series of iron-deficiency patients in order to establish the pathogenesis of such relationship. PATIENTS AND METHODS: Four-hundred and thirty-three patients were analysed. Pica was studied by introducing certain diet queries into the clinical history. All patients received oral iron and were periodically controlled with the usual clinico-haematological procedures. RESULTS: Pica was present in 23 patients (5.3%). Eight nourishing (namely, coffee grains, almonds, chocolate, ice, lettuce, carrots, sunflower seeds and bread) and 2 non-nourishing (clay and paper) substances were involved. A second episode of pica appeared in 9 cases upon relapsing of iron deficiency. Both anaemia and pica were cured by etiologic and substitutive therapy in all instances. No clear correlation was found with either socio-economic status or pathogenetic causes of iron deficiency and pica, and no haematological differences were seen between patients with pica and those without this alteration. CONCLUSIONS: (1) The pathogenesis of pica is unclear, although it appears unrelated to the degree of iron deficiency. (2) According to the findings in this series, pica seems a consequence of iron deficiency rather than its cause. (3) Adequate therapy can cure both conditions, although pica may reappear upon relapse of iron deficiency.
