OBJECTIVETo study the effects of desmopressin (DDAVP) on coagulation factor Ⅷ (FⅧ) and activated partial thromboplastin time (APTT) in children with mild hemophilia A.
METHODSEighteen children with mild hemophilia A were enrolled. DDAVP (0.3 μg/kg•d) was injected intravenously for 5 days. Plasma FⅧ levels and APTT were measured before and after DDAVP treatment.
RESULTSIn 16 of 18 children with mild hemophilia A, the bleeding symptoms, including the articular or musclar hematoma, were significantly alleviated as a result of DDAVP treatment. The plasma FⅧ levels increased significantly to (27±4)% and APTT was shortened to (66±10)s 60 minutes after the first dose of DDAVP treatment. The plasma FⅧ remained at the levels of 25%-30% during 3-4 days of DDAVP treatment. Five days after DDAVP treatment, the plasma FⅧ levels decreased [(21±3)%], and APTT was prolonged when compared with 1-4 days of DDAVP treatment.
CONCLUSIONSDDAVP treatment can increase plasma FⅧ levels and shorten APTT in children with mild hemophilia A. DDAVP is effective in the treatment of mild hemophilia A. The duration of DDAVP therapy for mild hemophilia A is recommended as 3 to 4 days.

2.Effect of desmopressin on platelet aggregation and blood loss in patients undergoing valvular heart surgery.
Chinese Medical Journal 2015;128(5):644-647
BACKGROUNDBlood loss after cardiac surgery can be caused by impaired platelet (PLT) function after cardiopulmonary bypass. Desmopressin or 1-deamino-8-D-arginine vasopressin (DDAVP) is a synthetic analog of vasopressin. DDAVP can increase the level of von Willebrand factor and coagulation factor VIII, thus it may enhance PLT function and improve coagulation. In this study, we assessed the effects of DDAVP on PLT aggregation and blood loss in patients undergoing cardiac surgery.
METHODSA total of 102 patients undergoing valvular heart surgery (from October 2010 to June 2011) were divided into DDAVP group (n = 52) and control group (n = 50). A dose of DDAVP (0.3 μg/kg) was administered to the patients intravenously when they were being re-warmed. At the same time, an equal volume of saline was given to the patients in the control group. PLT aggregation rate was measured with the AggRAM four-way PLT aggregation measurement instrument. The blood loss and transfusion, hemoglobin levels, PLT counts, and urine outputs at different time were recorded and compared.
RESULTSThe postoperative blood loss in the first 6 h was significantly reduced in DDAVP group (202 ± 119 ml vs. 258 ± 143 ml, P = 0.023). The incidence of fresh frozen plasma (FFP) transfusion was decreased postoperatively in DDAVP group (3.8% vs. 12%, P = 0.015). There was no significant difference in the PLT aggregation, urine volumes, red blood cell transfusions and blood loss after 24 h between two groups.
CONCLUSIONSA single dose of DDAVP can reduce the first 6 h blood loss and FFP transfusion postoperatively in patients undergoing valvular heart surgery, but has no effect on PLT aggregation.

OBJECTIVEApplying three treatment methods for enuresis in children with primary nocturnal enuresis (PNE) in a randomized controlled clinical trial (RCT) to compare the curative effects and characteristics of the three methods.
METHODSIf the parents and children consented to accept the treatment for 4 months and to keep on follow-up, the children diagnosed as primary nocturnal enuresis in the department of developmental and behavioral pediatrics in Shanghai Children's Medical Center from April 2003 to August 2004 were randomized into three groups: 52 children were in physio-psychological treatment group and were treated by utilizing the conditioning training role of alarm and other psychological and behavioral training programs; 46 children were in drug treatment group and were treated by taking DDAVP tablets orally; 40 children were in combined treatment group who were treated by applying the former two methods simultaneously. If the parents and children did not accept treatment, they were enrolled into the control group and were followed-up. Then, the curative effects of the four groups were compared statistically when the 4-month treatment was over and compared again 3 months later.
RESULTSApplying the physio-psychological treatment for 4 months, the short-term cure rate of children with enuresis was 75.0%. Three months after the end of the treatment, the long-term cure rate was 71.2%. As for drug treatment group, the short-term cure rate of children with enuresis was 47.8%, the long-term cure rate was 28.3%; As for combined treatment group, the short-term cure rate of children with enuresis was 85.0%, the long-term cure rate was 80.0%. The short-term and long-term curative effects of physio-psychological treatment group and combined treatment group were better than that of drug treatment group (P < 0.01). However, the short-term and long-term curative effects were not significantly different between physio-psychological treatment and combined treatment group (P > 0.05). Physio-psychological treatment exerts effects slowly, but showed sustained curative effects. While Drug treatment exerts effects rapidly, but the relapse rate was very high after discontinuation of the medication.
CONCLUSIONSPhysio-psychological treatment and drug treatment are currently generally recognized the best ways to treat enuresis, both of them are suitable for Chinese enuresis children, both of them showed good curative effects. Physio-psychological treatment develops children's ability to control nocturnal micturition, its curative effects were better than that of the drug treatment whilst its relapse rate is lower as compared to drug treatment. So, physio-psychological treatment is more suitable for widespread use to treat PNE in China.

Diabetes insipidus (DI) is characterized by excessive urination and thirst. This disease results from inadequate output of antidiuretic hormone (ADH) from the pituitary gland or the absence of the normal response to ADH in the kidney. We present a case of transient central DI in a patient who underwent a cardiopulmonary bypass (CPB) for coronary artery bypass grafting (CABG). A 44-yr-old male underwent a CABG operation. An hour after the operation, the patient developed polyuria and was diagnosed with central DI. The patient responded to desmopressin and completely recovered five days after surgery. It is probable that transient cerebral ischemia resulted in the dysfunction of osmotic receptors in the hypothalamus or hypothalamus-pituitary axis during CPB. It is also possible that cardiac standstill altered the left atrial non-osmotic receptor function and suppressed ADH release. Therefore, we suggest that central DI is a possible cause of polyuria after CPB.
