The effect of anticoagulation control on overall Health-Related Quality of Life (HRQoL) in patients taking warfarin in Malaysia has not been explored yet. Therefore, this study aimed to evaluate HRQoL among patients on warfarin in Malaysia. HRQoL among patients on warfarin was measured using WHOQOL-BREF (World Health Organization Quality of life Assessment: Brief Version). Descriptive and inferential statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 22. Out of 319 patients, more female patients were observed than the males (n = 221, 69.3%, and n = 98, 30.7% respectively). Mean scores for the physical (61.14 ± 15.96), psychological (68.58 ± 16.11), social (63.55 ± 27.06) and environmental domains (62.78 ± 17.58) were observed. Statistically, a significant association was found between the comorbidities other than CVDs with health satisfaction (p = 0.002), physical (p = 0.001), psychological (p < 0.001), social (p = 0.003) and environmental domains of the WHOQOL-BREF. A weak positive correlation between overall health satisfaction and the social domain (r = 0.153) and a moderate positive correlation between the physical and environmental domains (r = 0.628) of the WHOQOL-BREF were observed. Patients had overall better perceived HRQoL scores in the psychological domain as compared with the rest of the domains of the WHOQOL-BREF. Age, gender, employment status, education level, the indication of use and duration of warfarin therapy associated with overall perceived HRQoL. [ABSTRACT FROM AUTHOR]

Warfarin doses are greatly affected by polymorphism altering cytochrome P450 2C9 (CYP2C9) and vitamin K epoxide reductase complex subunit 1 (VKORC1) gene. This study evaluated the prevalence of alleles (either single or double) and carriers of single nucleotide polymorphisms (SNPs) in both genotypes CYP2C9 and VKORC1 in alkharj area, Saudi Arabia and its association with warfarin use risk. Total 112 samples were collected and genotyped using FlexiGene DNA Kit for isolation and StepOnePlus Real-Time PCR System by TaqMan allelic discrimination methods. The results indicated the frequency of 11%, 8% and 45% for CYP2C9 *2 *3 and VKORC1-1639 G > A polymorphism. And as a combination genotype it was 15.18% For both CYP2C9 and VKORC1 polymorphism, 27.67% for CYP2C9 and 42.86% for VKORC1. Non-carriers rate came to be at 30.3%. According to previously published dosing changes in warfarin for polymorphism carriers (single-double-triple). The predicted warfarin doses reduction in order of 1–1.6, 2–2.9, 2.9–3.7 mg/day. It was found that 72.3% of the study population was carrier of a type of polymorphism, 15.18% for two types of polymorphisms. These findings predict changes in warfarin metabolism and eventually dosing alteration among patients on warfarin. Both genotypes (CYP2C9 and VKORC1) require different dosing of warfarin than non-carriers in order to minimize the risk of warfarin overdosing and avoidance of the drug-related problems (DRPs).

The use of traditional medicines as a diuretic agent has been increasing in recent years. The diuretic activity of a number of plant extracts used as diuretic agents in ethnomedicine has been confirmed in experimental animals. However, despite the widespread use of Peganum harmala in traditional medicine, there is a paucity of data supporting its use as a diuretic agent. Therefore, the present study aimed to envisage the true effect and magnitude of diuresis of methanolic extract of P. harmala (MEPH) in comparison with a well-known diuretic drug furosemide using Wistar albino rats. MEPH was administered orally in three different doses (150, 300 and 450 mg/kg) to experimentally dehydrated rats. Furosemide (10 mg/kg orally) was used as a reference drug. The diuretic effect of the MEPH was evaluated by measuring urine volume, urine pH, urinary electrolyte levels, natriuretic and saliuretic effects. The urine volume (in mL) measured at 5 h and 24 h and electrolyte excretion (Na + , K + , and Cl − ) at 24 h duration were measured. The urine output and urinary electrolyte excretion were found to be significantly higher in rats treated with MEPH as compared to normal rats in a dose dependent manner ( P < 0.05). The results of our study were comparable to furosemide drug. Based on observed results, we can recommend that P. harmala may be an effective diuretic, however, toxicity studies should be conducted before administration. [ABSTRACT FROM AUTHOR]
