Kidney therapeutic potential of peptides derived from the bromelain hydrolysis of green peas protein

Nutrition profile and potency of RGD motif in protein hydrolysate of green peas as an antifibrosis in chronic kidney disease

OBJECTIVES

Fibrosis is the major cause of chronic kidney injury and the primary etiology in diabetic glomerulosclerosis. The initial study of protein hydrolysate of green peas hydrolyzed by bromelain (PHGPB) considered it to improve kidney function parameters and showed no fibrosis in histopathology features in gentamicin-induced nephrotoxicity rats. In the current study, we aimed to assess the nutrition profile and potency of RGD in PHGPB as antifibrosis in chronic kidney disease (CKD).

MATERIALS AND METHODS

Green peas (Pisum sativum) were hydrolyzed by bromelain from pineapple juice to obtain PHGPB. The amino acid content of PHGPB was measured using the UPLC method, while the primary structure used LC-MS/MS. Bioinformatic analysis was conducted using the Protease Specificity Predictive Server (PROSPER). The potency of RGD in PHGPB was characterized by determining the levels of Fibronectin (FN) and TGF-β1 in mesangial SV40 MES 13 cell lines of diabetic glomerulosclerosis.

RESULTS

The level of lysine was 364.85 mg/l. The LC-MS/MS data showed two proteins with 4-15 kDa molecular weight originated from convicilin (P13915 and P13919) which were predicted by PROSPER proteolytic cleavage, resulted in RGD in the LERGDT sequence peptide. PHGPB increased SV40 MES 13 mesangial cell proliferation that died from high-glucose levels (diabetic glomerulosclerosis model). PHGPB and RGD reduced the levels of FN and TGF-β1 in mesangial cell lines of diabetic glomerulosclerosis.

CONCLUSION

The nutrition profile and RGD motif in PHGPB show great potential as antifibrosis in CKD.

An Evaluation of Health Policy Implementation for Hajj Pilgrims in Indonesia

Background: For last decades, the mortality rate of hajj pilgrims from Indonesia was between 2.1 and 3.2 per 1000 hajj pilgrims. At the same time, morbidity affected 87% of the elderly (>65 years old), of which 83% faced high risk of health problems. This is a complex problem affecting hajj health care in Indonesia. The study was aimed to understand what extent of the hajj implementation on health care in Indonesia.

Methods: This review was conducted by abstracting of three studies in Indonesian hajj health care. Two of the studies were based on cross-sectional reviews, while one was a case–control study. The majority of the studies performed laboratory tests to evaluate the disease conditions among hajj pilgrims through secondary data.

Results: First study presented that hajj Posbindu (integrated post-coaching) was not functional in managing the health problems of the pilgrims. It shows that the stroke prevalence is 10.9 per 1000 people, Diabetes Mellitus (DM) 10.9% of the people, and coronary heart disease 1.5%. The second study expressed that, according to health isthitaah (policy implementation), there were 20% hajj pilgrims who delayed their trip because of health issues. Most of them had chronic kidney disease, dementia, or lung tuberculosis. The policy implementation of health isthitaah was not smooth; there was little collaboration between the Ministry of Health and Ministry of Religious Affairs, and the population was not sufficiently educated in the area, resulting in hajj pilgrims with poor knowledge, attitude, and practice in health isthitaah. This notion was enforced in the third study.

Conclusion: The coaching according to health isthitaah should be encouraged alongside collaboration between the Ministry of Health and Ministry of Religious Affairs. Socialization in public health has to increase according to health isthitaah, which can be done by district health centers.
