To assess the chemotactic activity and phagocytic response of neutrophilic polymorphonuclear leukocytes among women in the first five days postpartum.
A prospective, cross-sectional clinical-laboratory study was conducted. Data of 31 postpartum women during the first five days after vaginal delivery were compared with those of 24 healthy non-pregnant non-postpartum women matched for age. The inclusion criteria were postpartum, clinically and obstetrically healthy women; vaginal delivery, singleton pregnancy carried to term; non-hypertensive, hyperglycemic, allergic, malnourished or with autoimmune or neoplastic diseases; not having received vaccines or blood products in the last three months. The Control Group was chosen according to the same inclusion criteria but involving non-pregnant non-postpartum women. The chemotactic activity of neutrophilic polymorphonuclear leukocytes was assessed by determining the distance from directed migration to bacterial lipopolysaccharide, in three Boyden chamber assays. The phagocytic response was identified by assessing the Zymosan particles' ingestion in three assays carried out in Leighton tubes. The Student's t- test was used in the statistical analysis, adopting a 5% level of significance.
The chemotactic activity of neutrophilic polymorphonuclear leukocytes from postpartum women in the presence of homologous (73.2±6.9) and autologous (78.6±13.9) sera showed a significant increase compared to the values observed in the Control Group (64.1±4.1 and 66.6±5.4). Both chemotactic response and phagocytosis ingestion phase of neutrophilic polymorphonuclear leukocytes were significantly increased (p<0.05) in postpartum women compared to healthy non-pregnant and non-postpartum women.
There was an increase in the chemotactic activity and phagocytic response of neutrophilic polymorphonuclear leukocytes during the first five days after vaginal delivery in women.

PURPOSE: to quantify the presence of antithyroperoxidase (anti-TPO) and antithyroglobulin (anti-TG) antibodies, and the plasmatic concentrations of thyrotropin (TSH) and free thyroxine (FT4) in normal pregnant women. METHODS: a hundred twenty-seven pregnant women, residing in São Paulo, aged from 14 to 44 years old and gestational age > 16 weeks, determined by ultrasound performed before the 20th week of pregnancy were included in a transversal study performed in the prenatal clinic of Santa Casa de Misericórdia de São Paulo, from January 2003 to September 2004. Pregnant women using medicines or with thyroidopathy history were excluded. Antithyroperoxidase and antithyroglobulin antibodies were quantified by chemiluminescence immunoassay. The immunofluorimetry technique by time-resolved was used for determining the thyrotrophin and free thyroxine. The Student's t test, with significance of 5%, was used for analyzing the results. RESULTS: the frequency of antithyroid antibodies was 12.6% (8.6% of anti-TPO antibodies, and 4.6% of anti-TG antibodies). The average of TSH concentrations was 2.13±1.0 µU/ml, and the average of T4L was 0.9±0.5 ng/dl. It was observed alteration of the thyroid function in ten pregnant women (8%). Three of them had diagnosis of hypothyroidism: one in the clinical form of the disease, with increased TSH and decreased FT4; two in the subclinical form with increased TSH and normal FT4. Five presented decreased TSH and increased FT4, consistent with clinical hyperthyroidism and two were diagnosed with subclinical hyperthyroidism, with decreased TSH concentrations only. CONCLUSIONS: the frequency of antithyroid antibodies was 12.6% in pregnant women, the antithyroperoxidase antibodies being predominant over the antithyroglobulin antibodies. It was observed some thyroid dysfunction in 8% of the cases with alterations of TSH and/or T4L.

PURPOSE: the premature rupture of membranes (PROM) has been a reason for many investigations, amongst which the involved immune mechanisms. Ahead of the scarcity of studies related to the subject, this work had as objective to evaluate the serum values of IgA, IgG, IgM, C3 and C4 in pregnant women with pre-term PROM. METHODS: in this transversal study, 36 pregnant women had been enclosed, with gestational age between 23 and 37 weeks. Of this total, 15 women had had laboratorial and clinical diagnosis of PROM. Patients with beginning of the childbirth work, clinical signals of infection, clinical dysfunction with systemic repercussion had been excluded. Serum concentrations of immunoglobulin (IgA), immunoglobulin M (IgM) and immunoglobulin G (IgG), C3 and C4 had been evaluated in the patients with (study group) and without PROM (control group). Correlation among dosages; number of childbirths and time of rupture was determined by Spearman coefficient correlation (r value). RESULTS: serum levels of IgA (average±SD) had been significantly higher in the patients of the control group (271.0±107.0 versus 202.9±66.1; respectively, control and study group; p=0.024). There was no statistical difference when the levels of IgM, IgG, C3 and C4 had been compared between two groups. Significant association was not noticed between the number of childbirths and the IgA, IgM, IgG, C3 and C4 dosages (Spearman; r between -0,009 and 0,027; p>0,05). The average time of rupture of study group patients was of 19.1 hours (one - 72 hours), without association with the evaluated serum dosages. CONCLUSIONS: pregnant women with PROM show levels of IgA significantly lower than normal pregnant patients. The variable "number of childbirths" does not act as a factor of confusion in the comparative analysis of the dosages obtained in patients with or without PROM, as well as also it did not have association between the time of rupture and the immunoglobulin and complements serum dosages.
