Mirror syndrome associated with fetal cardiomyopathy

Mirror syndrome is a rare condition of generalized maternal oedema caused by fetal hydrops. A 37-year-old patient was admitted to our hospital because of suspected mirror syndrome caused by fetal cardiomyopathy. At 26th week of gestation patient developed bilateral pulmonary oedema as her condition rapidly deteriorated. Consequently, preterm labor was induced, percutaneous evacuation of fetal ascites was performed, and the patient finally vaginally delivered stillborn fetus. Although the initial postpartum period was severely complicated by hemorrhage, the condition of the patient significantly improved later, and she was discharged seven days after delivery. We believe this case is worth presenting due to its rarity and significant perinatal and obstetric challenges in treatment of those patients. Furthermore, preimplantation genetic testing could be performed to prevent at least some of the cases.

Stable Gastric Pentadecapeptide BPC 157 May Recover Brain-Gut Axis and Gut-Brain Axis Function

Conceptually, a wide beneficial effect, both peripherally and centrally, might have been essential for the harmony of brain-gut and gut-brain axes' function. Seen from the original viewpoint of the gut peptides' significance and brain relation, the favorable stable gastric pentadecapeptide BPC 157 evidence in the brain-gut and gut-brain axes' function might have been presented as a particular interconnected network. These were the behavioral findings (interaction with main systems, anxiolytic, anticonvulsive, antidepressant effect, counteracted catalepsy, and positive and negative schizophrenia symptoms models). Muscle healing and function recovery appeared as the therapeutic effects of BPC 157 on the various muscle disabilities of a multitude of causes, both peripheral and central. Heart failure was counteracted (including arrhythmias and thrombosis), and smooth muscle function recovered. These existed as a multimodal muscle axis impact on muscle function and healing as a function of the brain-gut axis and gut-brain axis as whole. Finally, encephalopathies, acting simultaneously in both the periphery and central nervous system, BPC 157 counteracted stomach and liver lesions and various encephalopathies in NSAIDs and insulin rats. BPC 157 therapy by rapidly activated collateral pathways counteracted the vascular and multiorgan failure concomitant to major vessel occlusion and, similar to noxious procedures, reversed initiated multicausal noxious circuit of the occlusion/occlusion-like syndrome. Severe intracranial (superior sagittal sinus) hypertension, portal and caval hypertensions, and aortal hypotension were attenuated/eliminated. Counteracted were the severe lesions in the brain, lungs, liver, kidney, and gastrointestinal tract. In particular, progressing thrombosis, both peripherally and centrally, and heart arrhythmias and infarction that would consistently occur were fully counteracted and/or almost annihilated. To conclude, we suggest further BPC 157 therapy applications.

Occurrence of Liver Damage and Obstetric Outcomes in Pregnant Women Diagnosed with Pruritus during Pregnancy: A Retrospective Study

AIM

A retrospective study of the occurrence of liver damage and obstetric outcomes in pregnant women diagnosed with pruritus.

METHODS

The following parameters were monitored in patients: aspartate aminotransferase (AST), alanine aminotransferase, gamma-glutamyl transferase, bilirubin (direct and total), hemoglobin, platelets, serum bile acid level, age of pregnant women, parity, pregnancy weight gain, birth weight, and gestational age at delivery. A total of 107 patients were included during a five-year period (2016-2020) and classified into three groups. Group A included 17 pregnant women with pruritus without elevated liver enzymes and bilirubin. Group B included 50 pregnant women with pruritus, elevated liver enzymes, and bilirubin. Group C included 40 pregnant women with pruritus and elevated bile acids (regardless of liver enzyme levels).

RESULTS

The groups did not significantly differ in patients' age and parity, but there was a statistically significant between-group difference in weight gain during pregnancy. The values of AST, ALT, GGT, LDH, and direct bilirubin were the highest in group B, and serum bile acids were expectedly the highest in group C. There was no statistically significant variation in the onset of labor and mode of delivery between groups. However, groups significantly differed in gestational age at delivery, newborn birthweight, and pregnancy prolongation from the onset of pruritus to delivery.

CONCLUSION

Further study is needed to assess the pathophysiologic mechanisms underlying intrahepatic cholestasis of pregnancy as well as any significant liver damage associated with pregnancy.

Gastric pentadecapeptide BPC 157 counteracts morphine-induced analgesia in mice

Previously, the gastric pentadecapeptide BPC 157, (PL 14736, Pliva) has been shown to have several beneficial effects, it exert gastroprotective, anti-inflammatory actions, stimulates would healing and has therapeutic value in inflammatory bowel disease. The present study aimed to study the effect of naloxone and BPC 157 on morphine-induced antinociceptive action in hot plate test in the mouse. It was found that naloxone and BPC 157 counteracted the morphine (16 mg/kg s.c.) - analgesia. Naloxone (10 mg/kg s.c.) immediately antagonised the analgesic action and the reaction time returned to the basic values, the development of BPC 157-induced action (10 pg/kg, 10 ng/kg, 10 microg/kg i.p.) required 30 minutes. When haloperidol, a central dopamine-antagonist (1 mg/kg i.p.), enhanced morphine-analgesia, BPC 157 counteracted this enhancement and naloxone reestablished the basic values of pain reaction. BPC 157, naloxone, and haloperidol per se failed to exert analgesic action. In summary, interaction between dopamine-opioid systems was demonstrated in analgesia, BPC 157 counteracted the haloperidol-induced enhancement of the antinociceptive action of morphine, indicating that BPC acts mainly through the central dopaminergic system.

The influence of gastric pentadecapeptide BPC 157 on acute and chronic ethanol administration in mice. The effect of N(G)-nitro-L-arginine methyl ester and L-arginine

BACKGROUND

Alcohol disturbances, NO stimulation (by the NO-precursor L-arginine), and/or NO-synthesis blockade (by N(G)-nitro-L-arginine methyl ester, i.e. L-NAME) were challenged with stable gastric pentadecapeptide BPC 157, which inhibits both acute alcohol intoxication and alcohol withdrawal symptoms.

MATERIAL/METHODS

Mice received intraperitoneally (i.p.) BPC 157 (10 microg/kg), L-NAME (10 mg/kg), and L-arginine (400 mg/kg), alone or in combination, 5 minutes before or after acute ethanol (4 g/kg i.p.) intoxication or after 0, 3, or 7 hours of withdrawal after drinking 20% alcohol for 13 days.

RESULTS

BPC 157 rapidly opposes the strongest disturbance presentations in acute intoxication (sustained ethanol anesthesia, complete loss of righting reflex, no reaction to external stimuli, hypothermia, 25% mortality) and withdrawal (prominent seizures). NO-agents: Aggravation of acute alcohol intoxication and opposition to withdrawal are common, but the later intervals affected by L-arginine and the action throughout the experiment by L-NAME are distinctive. Given together, L-arginine and L-NAME counteract each other, while either the "L-NAME presentation" (acute intoxication) or the "L-arginine presentation" (withdrawal) predominates. BPC157+NO-agent: In acute intoxication (L-NAME predominating in NO-system functioning to aggravate intoxication), both BPC157+L-NAME and BPC157+L-arginine follow the presentation of L-NAME, but without worsened mortality. In withdrawal (L-arginine predominating in NO-system functioning to oppose disturbance symptoms), BPC157+L-NAME follows the presentation of L-NAME, while BPC 157+L-arginine imitates that of L-arginine.

CONCLUSIONS

The relationships among pentadecapeptide BPC 157, the NO-system, acute alcohol intoxication, and opposed withdrawal may be important, presenting pentadecapeptide BPC 157 as a suitable alcohol antagonist.

Gastric pentadecapeptide BPC 157 effective against serotonin syndrome in rats

Serotonin syndrome commonly follows irreversible monoamine oxidase (MAO)-inhibition and subsequent serotonin (5-HT) substrate (in rats with fore paw treading, hind limbs abduction, wet dog shake, hypothermia followed by hyperthermia). A stable gastric pentadecapeptide BPC 157 with very safe profile (inflammatory bowel disease clinical phase II, PL-10, PLD-116, PL-14736, Pliva) reduced the duration of immobility to a greater extent than imipramine, and, given peripherally, has region specific influence on brain 5-HT synthesis (alpha-[14C]methyl-L-tryptophan autoradiographic measurements) in rats, different from any other serotonergic drug. Thereby, we investigate this peptide (10 microg, 10 ng, 10 pg/kg i.p.) in (i) full serotonin syndrome in rat combining pargyline (irreversible MAO-inhibition; 75 mg/kg i.p.) and subsequent L-tryptophan (5-HT precursor; 100 mg/kg i.p.; BPC 157 as a co-treatment), or (ii, iii) using pargyline or L-tryptophan given separately, as a serotonin-substrate with (ii) pargyline (BPC 157 as a 15-min posttreatment) or as a potential serotonin syndrome inductor with (iii) L-tryptophan (BPC 157 as a 15 min-pretreatment). In all experiments, gastric pentadecapeptide BPC 157 contrasts with serotonin-syndrome either (i) presentation (i.e., particularly counteracted) or (ii) initiation (i.e., neither a serotonin substrate (counteraction of pargyline), nor an inductor for serotonin syndrome (no influence on L-tryptophan challenge)). Indicatively, severe serotonin syndrome in pargyline + L-tryptophan rats is considerably inhibited even by lower pentadecapeptide BPC 157 doses regimens (particularly disturbances such as hyperthermia and wet dog shake thought to be related to stimulation of 5-HT2A receptors), while the highest pentadecapeptide dose counteracts mild disturbances present in pargyline rats (mild hypothermia, feeble hind limbs abduction). Thereby, in severe serotonin syndrome, gastric pentadecapeptide BPC 157 (alone, no behavioral or temperature effect) has a beneficial activity, which is likely, particular, and mostly related to a rather specific counteraction of 5-HT2A receptors phenomena.

The influence of gastric pentadecapeptide BPC 157 on acute and chronic ethanol administration in mice

The stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, M.W.1419), which was promising in inflammatory bowel disease (PL-10, PLD-116, PL-14736, Pliva) trials, protects against both acute and chronic alcohol-induced lesions in stomach and liver, but also, given peripherally, affects various centrally mediated disturbances. Now, in male NMRI mice BPC 157 (10 pg intraperitoneally, 10 ng and 10 microg, intraperitoneally or intragastrically) (i) strongly opposed acute alcohol (4 g/kg intraperitoneally) intoxication (i.e., quickly produced and sustained anesthesia, hypothermia, increased ethanol blood values, 25% fatality, 90-min assessment period) given before or after ethanol, and (ii) when given after abrupt cessation of ethanol (at 0 or 3 or 7 h withdrawal time), attenuated withdrawal (assessed through 24 hours) after 20%-alcohol drinking (7.6 g/kg) through 13 days, with provocation on the 14th day.
