Background: The serum level of soluble Human Leukocyte Antigen-antigen-D Related (HLA)-(DR) (sHLA-DR) may appear as a useful parameter to monitor maternal immune response during pregnancy. Objective: The aim was to compare HLA-G serum levels in patients with or without preeclampsia. Methods: Pregnant women seen at the “Mónica Pretelini Sáenz” Maternal-Perinatal Hospital (HMPMPS) were recruited at their first visit. Two groups were conformed: a) women with healthy pregnancies, and b) women with preeclampsia. The patients’ sociodemographic and laboratory data were introduced into the SPSS software program. HLA-G quantification was performed in peripheral blood samples through the Enzyme-linked Immunosorbent Assay (ELISA) method. Results: The total number of women seen was 16 (mean age, 24 ± 8 years), eight healthy women (mean age, 22 ± 3 years) and eight women with preeclampsia (mean age, 27 ± 7 years). Women with preeclampsia were older, heavier, had higher levels of Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Mean Arterial Pressure (MAP), and referred less sexual intercourse per week than healthy pregnant women. There was no difference in HLA-G levels. Conclusion: The sexual intercourse frequency is a major factor to develop preeclampsia and the serum HLA-G levels measured previous to the child delivery or cesarean are not different between women with or without preeclampsia.
<p><strong>Objective</strong>. To evaluate changes in the expression of tumor necrosis factor-α in patients with rheumatoid arthritis submitted to phototherapy. <strong>Materials and methods</strong>. This was an open label study, enrolling ten patients. The phototherapy scheme within a range of 425 to 650 nm, 11.33 Joules/cm2, 30 cm above the chest was as follows: a) 45-min daily sessions from Monday to Friday for 2 to 3 months; b) three, 45-min weekly sessions for 1 to 2 months; c) twice weekly 45-min sessions for 1 to 2 months, and d) one weekly session for 1 to 2 months until completion. Erythrocyte sedimentation rate, C-reactive protein and rheumatoid factor were measured in peripheral blood and tumor necrosis factor-α, interleukin-1β, and interleukin-10 in leukocytes by quantitative real-time Reverse transcriptase-Polymerase chain reaction. In all the patients the next indexes: Karnofsky scale, Rheumatoid Arthritis-specific quality of life instrument, Steinbrocker Functional Capacity Rating and the Visual Analog Scale were evaluated. <strong>Results</strong>. Erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor declined notoriously after the indicated sessions. In gene expression, there was a tendency in tumor necrosis factor-α to decrease after 1 month, from 24.5±11.4 to 18±9.2 relative units, without reaching a significant statistical difference. The four tested indexes showed improvement. <strong>Conclusion</strong>. Phototherapy appears to be a plausible complementary option to reduce the inflammatory component in rheumatoid arthritis.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
