Influence of beta(S) allele in the lipid peroxidation and antioxidant capacity parameters

Introduction: The oxidative process plays a fundamental role in the pathophysiology of sickle cell anemia (SCA), and population and environmental characteristics may influence redox balance. The aim of this study was to evaluate lipid peroxidation and antioxidant capacity in Brazilian Hb S carriers undergoing different therapies.MethodsBlood samples from 270 individuals were analyzed (Hb SS, n=68; Hb AS, n=53, and Hb AA, n=149). Hemoglobin genotypes were assessed through cytological, electrophoretic, chromatographic, and molecular methods. Plasma lipid peroxidation and antioxidant capacity were measured by spectrophotometric methods.ResultsPatients with SCA who used iron-chelating drugs combined with hydroxyurea, associated with regular transfusions, showed lower levels of TBARS (P <= 0.05), higher levels of TEAC (P <= 0.01), and lower TBARS/TEAC ratio (R=255.8). The redox profile of Hb AS subjects was not statistically different (P>0.05) from that of Hb AA subjects.ConclusionThe data suggest that oxidative stress is lower in the patients with SCA who received regular blood transfusions associated with the combined use of HU and iron chelators than the group received only HU. The redox system of the Hb AS carriers is compatible with the control group.

Leg Amputation for an Extensive, Severe and Intractable Sickle Cell Anemia Ulcer in a Brazilian Patient

A 35-year-old African Brazilian patient had sickle cell anemia complicated with recurrent vasoocclusive (VOC) crises and refractory painful leg ulcers for 16 years. The ulcers started over both medial malleoli and expanded gradually. The ulcer on the left leg spread from the foot to the knee circumferentially and was refractory to all forms of therapy within the frame work of multi-disciplinary care. The patient agreed to a below the knee amputation of the left leg. He felt much better after the amputation but developed severe neuropathic phantom pain that was well controlled medically. He could differentiate the sickle cell anemia and ulcer pain from the neuropathic pain. About 6 months after the amputation he had dengue fever with fatal outcome. This is the first report of treatment of refractory sickle cell anemia leg ulcer with amputation and probably the first report of a Brazilian patient with sickle cell anemia and dengue fever.

Effects of autohemotherapy on hematological responses in Wistar female rats Autohemotherapy in rats

Introduction: Autohemotherapy is a type of treatment that have acquired an opposite role and have presented its efficiency strived by the medical community for many reasons. In this study we aimed to evaluate the effects of authohaemotherapy on hematological response. Method: We used Wistar female rats (300g). The study consisted in a control group and a treatment group, blood samples were collected at the first day and at the eighth day after the application. In the both groups we collected 300 μl of blood from each rat through a syringe with a previously prepared solution of 30 μl of sodium citrate 3.2%. In the autohemotherapy group the blood sample was immediately injected in the quadriceps muscle on the back of the thigh hind limb. Rats from the control group did not receive intramuscular blood application. The cellular count was done through flow cytometry and the samples were dosed for immunoglobulin. Results: In the both groups we observed increased production of erytrocites, hemoglobin and platelet (p<0.05). However, there was reduction of basophil in the control group and reduction of lymphocyte, monocyte and neutrophil in the both groups. No effects were observed in IgA, IgG and IgM levels. Conclusion: Autohemotherapy did not influence hematological responses in Wistar female rats.
