METHODOLOGY/PRINCIPLE FINDINGS: The D. siamensis monovalent antivenom displayed extensive recognition and binding to proteins found in D. siamensis venom, irrespective of the geographical origin of those venoms. Similar immunological characteristics were observed with the Hemato Polyvalent antivenom, which also uses D. siamensis venom as an immunogen, but binding levels were dramatically reduced when using comparator monovalent antivenoms manufactured against different snake species. A similar pattern was observed when investigating neutralization of coagulopathy, with the procoagulant action of all four geographical venom variants neutralized by both the D. siamensis monovalent and the Hemato Polyvalent antivenoms, while the comparator monovalent antivenoms were ineffective. These in vitro findings translated into therapeutic efficacy in vivo, as the D. siamensis monovalent antivenom was found to effectively protect against the lethal effects of all four geographical venom variants preclinically. Assessments of in vivo nephrotoxicity revealed that D. siamensis venom (700 μg/kg) significantly increased plasma creatinine and blood urea nitrogen levels in anaesthetised rats. The intravenous administration of D. siamensis monovalent antivenom at three times higher than the recommended scaled therapeutic dose, prior to and 1 h after the injection of venom, resulted in reduced levels of markers of nephrotoxicity and prevented renal morphological changes, although lower doses had no therapeutic effect.

Methods: We conducted a single-arm intervention study at the Clinical Lab of Community Medicine, Universiti Sains Malaysia, and included 31 healthy individuals aged between 30 and 60 years old. Wet cupping therapy was performed at five treatment points at the beginning of the study and repeated after three months. Health outcomes at baseline, one, three, and four months were assessed for FBS, renal function parameters (urea, creatinine, and uric acid), systolic blood pressure (SBP), and von Willebrand factor (vWF).

Results: Forty-five percent of participants were female, and the mean age of study participants was 44.9±6.4 years. Wet cupping therapy significantly reduced FBS, serum urea, and serum creatinine at one, three, and four months compared with baseline values. Serum uric acid and SBP showed a significant reduction at one and four months compared with baseline. The vWF (a measure of endothelial function) had a 4.0% reduction at four months compared to baseline, with a mean difference of 5.3 (95% confidence interval (CI): 2.20 = 8.55; p = 0.002).

METHOD: The meta-analysis included all studies that examined the effect of prebiotic, probiotic, and synbiotic supplements on one or more renal function parameters and had a control group. We searched July 1967 through to March 2016 MEDLINE, Scopus, and Google Scholar databases.

RESULTS: Of 437 studies, 13 were eligible for inclusion in the meta-analysis. GFR levels tended to be reduced; whereas creatinine levels increased in the intervention group compared with the placebo group, both in a non-significant manner. The pooled effect on BUN demonstrated a significant decline compared with the placebo group (MD, -1.72 mmol/L; 95% confidence interval [CI], -2.93 to -0.51; P = 0.005). Urea significantly decreased after intervention (-0.46 mmol/L; 95% CI, -0.60 to -0.32; P <0.0001). The UA levels significantly increased in the intervention group compared with the placebo group (12.28 µmol/L; 95% CI, 0.85-23.71; P = 0.035).
