Associação entre expressão de receptores TLR2 e TLR4 e produção de TNF-alpha e IL-10 por monócitos de gestantes portadoras de pré-eclâmpsia

Preeclampsia (PE) is a pregnancy specific syndrome characterized by a systemic inflammatory response, with higher intensity than that observed in normal pregnancy. Cells of the immune system, such as monocytes and granulocytes are endogenously activated and secrete high levels of free radicals and inflammatory cytokines. The objective of this study was to assess the activation state of monocytes from pregnant women with preeclampsia by endogenous expression of TLR2 e TLR4 receptors and to correlate the expression of TLR2 and TLR4 on monocytes surface of pregnant women with PE with the production of tumor necrosis factor-alpha (TNF- and interleukin-10 (IL-10) by these cells stimulated or not with peptidoglycan (PG) and lipopolysaccharide (LPS), as agonists agents of TLR2 and TLR4, respectively. We evaluated 15 pregnant women with PE, 15 normotensive pregnant women (NT) and 15 non-pregnant (NP). Peripheral blood monocytes were incubates in the presence or absence of LPS or PG. The supernatant obtained after 18h of culture was aspirated and used for TNF- and IL-10 determination by enzyme immunoassay (ELISA). The endogenous expression of TLR2 and TLR4 receptors was evaluated by flow cytometry. Our results showed significant highly concentrations of TNF- and TLR4 expression in monocytes of preeclamptic women when compared with NT and NP. Normal pregnant women presented higher levels of IL-10 in comparison with PE and NP groups. TLR2 expression was similar in the three groups studied. Therefore, our study highlights the important role of TLR4 in PE and the consequent high production of TNF- by monocytes of these patients, as well as the potential mechanism involving low levels of IL-10 in the pathophysiology of the disease. These observations demonstrate the strong link between the pathology of PE and the immune system of these patients

Hydroxyurea in the sickle cell anemia: toxicity and effectiveness

Objective: to evaluate the use of hydroxyurea with regard to effectiveness and toxicity in people with sickle cell anemia. Method: this is a retrospective descriptive study, developed with 57 medical records of patients with sickle cell anemia, treated at the University Hospital Center of Campo Grande (Mato Grosso do Sul, Brazil), from 1993 to 2005. Inclusion criteria: electrophoresis of hemoglobin in medical record; regular use of drugs, for an average of 196 weeks; dosage; and hematological analyses before starting treatment. Exclusion criteria: living with other hemoglobinopathies. The variables evaluated were: neutrophils count; platelets; leukocytes; hemoglobin; time using hydroxyurea; drug response to the optimal dosage; and number and type of episodes of hospitalization. The research protocol was approved by the Ethics Committee of Universidade Federal de Mato Grosso do Sul, under the Protocol 645. Results: of the 57 medical records, 3 cases were evaluated. Comparing the hematological values, according to Portaria 872, enacted on 11/12/2002, it was found that: cases A, B, and C present an use of hydroxyurea (500 mg/day) for four years, with an average of 196 weeks. Case A, female, decreased painful episodes and frequency of hospitalization, keeping hematological values with no toxicity. In Case B, female, there was one hospitalization due to pain crises and important hemolysis. It stood out, in case C, male, neutropenia with hematological values < 2,000/mm3 . Conclusion: in the cases analyzed, we observed a drop in the number of hospitalizations with the decrease in painful crises from three to one a year, and there was no toxicity with regard to the dosage and time using hydroxyurea, in all three cases. For more comprehensive results, one suggests further study on this therapy with significant samples of this clientele.
