Case report on splenic abscess with pleural effusion caused by enteric fever

Splenic abscess is an infrequent complication of enteric fever caused by Salmonella typhi. The incidence rate ranges from 0.14-2%. Clinical manifestations are often nonspecific and may be presented as fever with left upper quadrant abdominal pain and a palpable tender mass. Diagnosis is often difficult and splenic abscess management is based on surgical interventions and antibiotic therapy. In this case report we would like to highlight splenic abscess with left reactive pleural effusion as a rare complication of Salmonella typhi infection

Cocos nucifera L. inflorescence extract: An effective hepatoprotective agent

The flowering inflorescence of Cocos nucifera, a main constituent of several traditional drug formulations was investigated with a view to study the effect of the acetone extract of C. nucifera inflorescence (CnAE) on acetaminophen-induced hepatotoxicity. The total phenol and flavonoid contents of the extract are found to be 222.6 µg gallic acid equivalent/g and 120.8 µg quercetin equivalent/g, respectively. The LD50 value was >5000 mg/kg b.w. The antioxidant activity was assessed using three methods, namely, 2,2’- diphenyl-1-picryl hydrazyl assay, 2,2’-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay and ferric reducing antioxidant power assay and the IC50 values were found to be 65.72, 66.94 and 89.84 μg/mL, respectively. Effect of CnAE (100, 200 and 400 mg/kg b.w.) and silymarin (100 mg/kg b.w.) against acetaminophen-induced liver toxicity was evaluated in Wistar rats. The study showed that CnAE pre-treated groups remarkably prevented the increase in serum alanine amino transferase, aspartate amino transferase and alkaline phosphatase level and decrease in the level of liver superoxide dismutase, reduced glutathione, glutathione-S-transferase and glutathione peroxidise. The extract also suppressed the elevated level of malondialdehyde. The biochemical determinations supported the histopathological examination and blood parameter findings. The findings of our study indicated that the phenolic-rich CnAE could be an interesting alternative candidate against acetaminophen-induced hepato-toxicity and associated oxidative stress

Epidemiology, baseline characteristics and risk of progression in the first South-Asian prospective longitudinal observational IgA nephropathy cohort

Introduction: Glomerular Research And Clinical Experiments-IgA Nephropathy in Indians (GRACE-IgANI) is the first prospective South Asian IgAN cohort with protocolized follow-up and extensive biosample collection. Here we report the baseline clinical, biochemical, and histopathologic characteristics of GRACE IgANI and calculate baseline risk of progression for the cohort. Methods: 201 incident adults with kidney biopsy-proven primary IgAN were recruited into GRACE-IgANI between March 2015 and September 2017. As of April 30, 2020, the cohort had completed a median followup of 30 months (interquartile range [IQR] 16-39). Results: The commonest clinical presentation in GRACE IgANI was hypertension, with or without proteinuria, and nephrotic-range proteinuria was present in 34%, despite Conclusions: The predicted risk of progression in this cohort was considerable. Over the next 5 years, we will dissect the pathogenic pathways that underlie this severe South Asian IgAN phenotype

Three-Year Clinical Outcomes of the First South Asian Prospective Longitudinal Observational IgA Nephropathy Cohort

INTRODUCTION: Glomerular Research And Clinical Experiments—IgA Nephropathy in Indians (GRACE-IgANI) is the first prospective South Asian IgA nephropathy (IgAN) cohort with prespecified objectives, protocolized longitudinal follow-up, and extensive biosample collection. The baseline risk scores predicted high risk of kidney disease progression. METHODS: A total of 195 of 201 patients (97%) completed 3-year follow-up in September 2020. All patients received optimized supportive care, and those at high risk of progression were offered systemic corticosteroids. RESULTS: A total of 76 patients (76 of 193, 39.4%) had rapid progression in 3 years (≥5 ml/min per 1.73 m(2) decline in estimated glomerular filtration rate [eGFR] per year). A total of 72 patients (72 of 195, 36.9%) experienced the composite outcome (CO), defined as ≥50% fall in eGFR, eGFR < 15 ml/min per 1.73 m(2), commenced kidney replacement therapy or death, in 3 years. At each scheduled follow-up, achievement of proteinuria level < 1 g/d significantly delayed the time to the CO. The receiver operating characteristic curve of average annual decline in eGFR ≥ 5 ml/min per 1.73 m(2) had 86% sensitivity and 89% specificity for CO in 3 years and had good discrimination from 1 year onwards (area under the curve 0.8, SE 0.04, 95% CI 0.7–0.9, P < 0.0001). The significant predictors of CO by Cox proportional-hazards model were as follows: baseline MEST-T2 score (hazard ratio [HR] 3.3, 95% CI 1.7–6.5, P < 0.001), along with 24-hour urine protein level ≥ 1 g/d (HR 2.1, 95% CI 1.1–3.9, P = 0.02), eGFR < 60 ml/min per 1.73 m(2) (HR 2.9, 95% CI 1.1–7.6, P = 0.03), and rate of eGFR decline ≥ 5 ml/min per 1.73 m(2)/yr (HR 2.7, 95% CI 1.6–4.8, P < 0.001) all measured at 6 months. Mortality was 11 of 195 (5.6%). CONCLUSION: We identified longitudinal clinical variables measured at 6 months and ≥5 ml/min per 1.73 m(2) annual fall in eGFR after kidney biopsy as important predictors for composite outcome in addition to baseline histology

Citostatsko i protuupalno djelovanje polisaharida biljke Ganoderma lucidum

In this study, polysaccharides were isolated from Ganoderma lucidum (Polyporaceae) and their antitumor and anti-inflammatory activities were investigated using in vivo models. Potential antitumor activity was shown by G. lucidum polysaccharides (GLP) against solid tumor induced by Ehrlich’s ascites carcinoma cells. GLP at 100 mg kg–1 body mass showed 80.8 and 77.6 % reduction in tumour volume and tumour mass, respectively, when administered 24 h after tumour implantation. Again, GLP at the same dose but when administered prior to tumour inoculation, showed 79.5 and 81.2 % inhibition of tumour volume and tumour mass, respectively. GLP showed significant dose-dependent activity in carrageenean-induced (acute) and formalin-induced (chronic) inflammation assays. At 100 mg kg–1, GLP exhibited 57.6 and 58.2 % inhibition in carrageenean-induced and formalin-induced assays, respectively.U radu je ispitano in vivo citostatsko i protuupalno djelovanje polisaharida (GLP) izoliranih iz biljke Ganoderma lucidum (Polyporaceae). Ispitivani polisaharidi pokazali su potencijalno antitumorsko djelovanje na Ehrlichov ascitesni tumor. GLP su u dozi od 100 mg kg1 tjelesne mase inhibirali volumen tumora za 80,8, a njegovu masu za 77,6 %, kada su primijenjeni 24 h nakon implantacije tumora. Ako se GLP daju u istoj dozi prije inokulacije tumora, inhibiraju volumen tumora za 79,5, a njegovu masu za 81,2 %. GLP pokazuju značajno, o dozi ovisno, protuupalno djelovanje u karagenan testu (akutna upala) i formalin testu (kronična upala). U dozi od 100 mg kg1, GLP inhibiraju upalne procese za 57,6 odnosno 58,2 % u testu s karagenanom, odnosno formalinom
