The extensive use of opioid-based pain management strongly correlates with poor cardiovascular and cardiorenal outcomes. Our recent studies suggest that treatment with kappa opioid receptor (KOR) agonist BRL 52537 leads to the progression of chronic kidney disease (CKD) and aggravation of salt-sensitive hypertension. We hypothesize that stimulation of KORs leads to blood pressure elevation, albuminuria, and kidney damage in healthy Sprague-Dawley (SD) rats. To characterize the effect of the KOR agonist BRL 52537 on the development of blood pressure and kidney function in vivo , SD rats were treated with a daily i.v. bolus infusion of BRL 52537 or a corresponding vehicle. To test the contribution of KOR stimulation on calcium homeostasis in podocytes, BRL 52537 was used on freshly isolated glomeruli from SD rats. Single-channel analysis was applied to assess the effect of KORs stimulation on TRPC6 channel activity in the human immortalized podocytes. Chronic treatment with BRL 52537 leads to increased mean arterial pressure (88±1 vs 101±4 mmHg, vehicle vs treated, p<0.05), podocyte basal calcium (90±12 vs 216±16 a.u., vehicle vs treated, p<0.05), and GFB impairment in SD rats which is reflected by a transient increase in albumin excretion (Alb/cre ratio 0.35±0.1 vs 0.72±0.2, vehicle vs treated, p<0.05). Cumulative probability distribution analysis of the glomerular injury score revealed a rightward shift toward a high glomerular injury score in the group treated with BRL 52537 (p<0.05). Angiotensin II level was higher in a BRL-treated group (156±17 vs 232±59 pmol, vehicle vs treated, p=0.065); however, it did not reach a statistical difference. Acute application of BRL 52537 resulted in sustained calcium response (0.23±0.01 a.u., Fluo4/FuraRed, maximum calcium response) in freshly isolated glomeruli from SD rats. Furthermore, patch-clamp experiments in human immortalized podocytes (cell-attached configuration) revealed that BRL 52537 activated TRPC6 channels. Taken together, these data support the hypothesis that administration of opioids in SD rats leads to activation of the KOR/TRPC6 pathway, which in turn led to glomerular filtration barrier impairment, increased glomerular damage, and blood pressure elevation.

Westudied patterns of antenatal care in low- versus high-risk pregnancies in Lebanon comparing 538 women after delivery in urban Beirut with rural Baka’a. Most women had 9 antenatal care visits with an obstetrician, starting in the first trimester. Care for high-risk and low-risk pregnancies was similar in terms of type of provider, number of visits and timing of first visit. More high-risk women had advice about special diets, supplements and laboratory tests. Maternal and fetal outcomes showed that, controlling for area and pregnancy risk, more antenatal visits were associated with fewer preterm deliveries, more caesarean sections and fewer cases of postpartum depression. Overall, differences between risk groups were small
