Clinical significance of anti-D IgG screening and titer detection in 286 RhD negative pregnant women / 中国当代儿科杂志

<p><b>OBJECTIVE</b>Anti-D IgG in RhD negative pregnant women is the main antibody of Rh-induced hemolytic disease of newborn (HDN). The study aimed to investigate the clinical significance of anti-D IgG screening and titer detection in RhD negative pregnant women.</p><p><b>METHODS</b>Sera of 286 RhD negative pregnant women were collected. Microtube column indirect antiglobulin test was used to screen and identify anti-D IgG. The indirect antiglobulin test was used to test the titer of anti-D IgG.</p><p><b>RESULTS</b>Anti-D IgG was identified in 21 cases (7.3%). The titer of anti-D showed an increasing trend with pregnancy progresses. The clinical outcomes of 12 fetuses (newborns) from positive anti-D pregnant women were observed. Two cases died in utero, 2 cases did not show abnormality and 8 cases had hemolysis. The 8 cases with hemolysis were treated with exchange transfusion or blood transfusion, and they had a good prognosis.</p><p><b>CONCLUSIONS</b>The screening and titer detection of anti-D IgG in RhD negative pregnant women are valuable in the prediction and treatment of HDN.</p>

Lymphoplasmapheresis for Guillain-Barre syndrome / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the clinical therapeutic effect and security of lymphoplasmapheresis (LPE) for Guillain-Barre syndrome (GBS).@*METHODS@#Sixty-six GBS patients were randomly divided into 2 groups: the therapy group (33 patients) were treated with LPE in addition to the medical treatment; the control group (33 patients) only accepted the medical treatment. The therapeutic effect was evaluated with the initial recovery time of myodynamia and the myodynamia score difference, and the side effect of the therapy group was observed.@*RESULTS@#The therapy group were treated with LPE for 48 times,1.5 times per person. The average initial recovery time was quicker in the therapy group compared with that in the control group [(6.45+/-3.01) vs (8.36+/-3.83) days]. The difference of limb myodynamia score between pre-treatment and post-treatment in the therapy group was more than that in the control group. The improved number in the therapy group was more than that in the control group, but the ineffective number in the therapy group was not as many as that in the control group. The total effective rate in the therapy group was higher than that in the control group (51.5% vs 27.7%); the average hospital day in the therapy group was shorter than that in the control group [(19.42+/-7.25) vs (24.00+/-8.64) days]; and the difference had statistical significance(P0.05). After the second and the third LPE, the average myodynamia score continued to rise, and the difference had statistical significance (P<0.05). The incidence rate of side effects in the therapy group was 12.5%. Urticaria and hypotension were the major side effects, but they were light and could be relieved by symptomatic treatment.@*CONCLUSION@#The therapeutic effect of LPE is definite, and the side effect is scarce. LPE is safe and effective, and it is worth of generalization and applying in clinical practice.
