Managing schizophrenia has never been a trivial matter. Furthermore, while classical antipsychotics induce extrapyramidal side effects and hyperprolactinaemia, atypical antipsychotics lead to diabetes, hyperlipidaemia, and weight gain. Moreover, even with newer drugs, a sizable proportion of patients do not show significant improvement. Alstonine is an indole alkaloid identified as the major component of a plant-based remedy used in Nigeria to treat the mentally ill. Alstonine presents a clear antipsychotic profile in rodents, apparently with differential effects in distinct dopaminergic pathways. The aim of this study was to complement the antipsychotic profile of alstonine, verifying its effects on brain amines in mouse frontal cortex and striatum. Additionally, we examined if alstonine induces some hormonal and metabolic changes common to antipsychotics. HPLC data reveal that alstonine increases serotonergic transmission and increases intraneuronal dopamine catabolism. In relation to possible side effects, preliminary data suggest that alstonine does not affect prolactin levels, does not induce gains in body weight, but prevents the expected fasting-induced decrease in glucose levels. Overall, this study reinforces the proposal that alstonine is a potential innovative antipsychotic, and that a comprehensive understanding of its neurochemical basis may open new avenues to developing newer antipsychotic medications.

Background: Therapies for hyperglycemic treatment, including insulin and oral diabetes medications, have been confirmed to cause several side effects. Thus, finding new drugs with fewer side effects is of high importance. Salung leaf herb (Psychotria malayana Jack) reported used in traditional societies as a treatment for diabetes. However, the scientific proof of this plant for diabetes treatment is still lacking.Objective: To evaluate the antidiabetic effect of the P. malayana jack in induced type 1 diabetic rats by assessing blood glucose level and pancreatic cells in white rats.Methods: Alloxan used to induce type I diabetes. Rats randomly divided into six groups. A Group P1 received 250 mg/kg BW; group P2 received 500 mg/kg BW, group P3 received 1000 mg/kg BW. While group 4 basal received no treatment, group 5 received distilled water as a negative control, and group 6 received glibenclamide as a positive control. Medications are given for six days. Glucose levels were measured, and observation of pancreatic Langerhans cell damages.Results:  A decrease in blood glucose levels observed in all treatment groups. The most significant reduction (49.76%; 1000 mg/kg BW) occurred in the P3 group. Morphological features of pancreatic Langerhans cell damage were slightly high in the P1 group.Conclusion: P. malayana Jack can consider having an antidiabetic effect in a type 1 diabetic rat by reducing blood glucose levels.

Diabetic kidney disease (DKD) is a major cause of end-stage kidney disease, and it is crucial to understand the pathophysiology of DKD. The control of blood glucose levels by various glucose-lowering drugs, the common use of inhibitors of the renin–angiotensin system, and the aging of patients with diabetes can alter the disease course of DKD. Moreover, metabolic changes and associated atherosclerosis play a major role in the etiology of DKD. The pathophysiology of DKD is largely attributed to the disruption of various cellular stress responses due to metabolic changes, especially an increase in oxidative stress. Therefore, many antioxidants have been studied as therapeutic agents. Recently, it has been found that NRF2, a master regulator of oxidative stress, plays a major role in the pathogenesis of DKD and bardoxolone methyl, an activator of NRF2, has attracted attention as a drug that increases the estimated glomerular filtration rate in patients with DKD. This review outlines the altered stress responses of cellular organelles in DKD, their involvement in the pathogenesis of DKD, and discusses strategies for developing therapeutic agents, especially bardoxolone methyl.

Due to less extrapyramidal side-effects ,atypical antipsychotics use in psychiatry has increased a lot. But it is associated with other metabolic and endocrine side effects. Olanzapine is one such antipsychotic that less likely to cause hyperprolactinemia which can present as amenorrhea in patients.Here we present a rare case of olanzapine induced amenorrhoea reversed by switching to Aripiprazole.

Blood Monitoring

The development of atypical antipsychotics has revolutionised the treatment of schizophrenia, as well as providing new insights into its cause. The archetypal atypical antipsychotic is clozapine, which has therapeutic advantages over traditional antipsychotics, as well as a low potential for producing extrapyramidal side-effects (EPS) (Kane et al, 1988). However, clozapine causes agranulocytosis in 1% of patients, and there has consequently been a search for novel atypical antipsychotics, as efficacious as clozapine, but without the need for intensive blood monitoring. There has been much discussion of the definition and characteristics of an atypical antipsychotic drug, and an operational understanding seems to have been agreed upon, that atypical drugs have therapeutic efficacy in treating schizophrenia, without producing EPS (Deutch et al, 1991; Kerwin, 1994).

Cognitive Side Effects

New onset hallucinations and delusions are rare after isolated concussion and should trigger a search for other causes: Schizophrenia (relatively common in young adults), drug abuse, alcohol or drug withdrawal, and delirium due to infection or sleep deprivation should be considered. Importantly, if the psychosis is dangerous or potentially dangerous, think about safety first. This may require inpatient admission to a psychiatric service. If outpatient treatment is required, atypical antipsychotics should be used in as low a dose as possible to minimize cognitive side effects. Aripiprazole (Abilify) is associated with less weight gain than other atypical antipsychotics. Risperidone (Risperdal) is the least expensive. Quetiapine (Seroquel), or rarely Clozaril, are the best choices when parkinsonism is a comorbidity.

Order Of Magnitude

Ischemic conditions in limbs can be provoked by occlusion with inflatable cuffs. The period of development of ischemia to an extent where muscle exercise is no longer possible is drastically shortened by muscle exercise itself. Blood obtained by venepuncture of the forearm under these conditions showed no differences in pH, PO2. pCO2 , and lactate and glucose levels in comparison with the blood taken before occlusion A special technique of blood sampling under low flow flushing conditions was developed, by which blood reflecting the ischemic state is obtained nearly without dilution from the cubital vein. This is demonstrated by measurements of pH, pO2 , pCO2, lactate concentration and osmolarity, which, under the latter conditions, revealed changes of about 0.3 pH units, 20 mm Hg, 80 mm Hg, 90 mg/dl, and 30 mosm/1 respectively. The extent of local changes of these parameters in the microcirculation of muscle tissue in the state of ischemic pain is suggested to be of the same order of magnitude.

Atypical antipsychotics have become a common therapeutic option in both schizophrenia and bipolar disorder. However, these medications come with a high risk of metabolic side effects, particularly dyslipidemia and insulin resistance. Therefore, identification of patients who are at increased risk for metabolic side effects is of great importance. The genetics of fatty acid metabolism is one area of research that may help identify such patients. Therefore, in this present study, we aimed to determine the effect of one commonly studied genetic polymorphism from both fatty acid desaturase 1 (FADS1) and FADS2 gene on a surrogate measure of insulin resistance and lipid levels in a metabolically high-risk population of patients largely exposed to atypical antipsychotics. This study used a cross-sectional design, fasting blood draws, and genetic analysis to investigate associations between polymorphisms, haplotypes, and metabolic measures. A total of 320 subjects with schizophrenia (n=226) or bipolar disorder (n=94) were included in this study. The mean age of the population was 42.5 years and 45% were male. A significant association between FADS1 and FADS2 haplotypes was found with insulin resistance while controlling for confounders. Further investigation is required to replicate this finding.
