Acute kidney injury of infectious etiology in monsoon season: A prospective study using acute kidney injury network criteria

The epidemiological pattern of acute kidney injury (AKI) in tropical countries during monsoon reflects infectious disease as the most important cause. AKI is a confounding factor and may be overlooked by primary health-care providers and underreported in health statistics. The present study prospectively helps estimate the burden of disease and analyze etiology, clinical profile, and outcome in a tertiary care hospital of a metropolitan city in a tropical country. The study period included monsoon season of 2012 and 2013, a total of 8 months. AKI staging was done as per the AKI Network (AKIN) criteria. Patients were treated for primary disease. Renal replacement therapy (RRT) was given as required. Patients were followed up during hospitalization till recovery/death. Out of a total of 9930 admissions during this period, 1740 (17.52%) were for infections and 230 (2.31%) had AKI secondary to infectious diseases during monsoon. The incidence of AKI (230/1740) in infectious diseases during monsoon was 13.21%. The study population (n = 230) comprised 79.5% of males and the mean age was 40.95 ± 16.55 years. Severe AKI: AKIN Stage III was seen in 48.26% of patients and AKIN Stage I in 41.74%. The most common etiology of AKI was malaria (28.3%) followed by acute gastroenteritis (23%), dengue (16.5%), leptospirosis (13%), undifferentiated fever (10.4%), more than one etiology (5.4%), and enteric fever (3.5%). RRT was required in 44.78% of patients. Requirement for RRT was maximum in patients with more than one etiology followed by leptospirosis, malaria, dengue, and least in typhoid. The overall mortality was 12.17%. In multivariate analysis, vasopressor support and assisted ventilation were risk factors for mortality

Phytochemical analysis of Clerodendron infortunatum Linn. leaves in various seasons by different solvent and extraction techniques

Clerodendron infortunatum Linn is widely used for the treatment of malaria and vermifuge, scorpion and snake bites, tumors, inflammation, bronchitis and in wound healing. The present study was carried out to estimate the variation in the amounts of Gallic acid, Rutin and Quercetin in Clerodendron infortunatum Linn.leaves extracts collected in different seasons using high-performance thin layer chromatography (HPTLC).In this study, leaves of C. infortunatum were subjected to methanol extractions using Soxhlet method and cold maceration. The leaves were collected in different seasons in the months of December (Sample A -Shishir rutu-Winter season) and July (Sample B -Varsha Rutu -Rainy season). The methanolic extracts were subjected to HPTLC study & using CAmag HPTLC system, employing a mixture of toluene:ethyl acetate:formic acid:methanol(3:6:1.6:0.4 ) as the mobile phase with densitometric scanning at 254nm. Quantity of Quercetin is found in both samples, extracted by Soxhlet method. Its quantity is higher in the winter season. Quantity of Gallic acidis found in both samples. Its quantity is the same in Sample B by Soxhlet extraction method & maceration method respectively. Quantity of Rutin is found in both the samples extracted by Soxhlet & maceration methods. It is higher in the sample-A. The present HPTLC method is used for the detection and quantization of Gallic acid, Quercetin and Rutin of C. infortunatum leaves. It needs to study the season wise and region wise variation of phytochemicals in useful parts of all other plants by different extraction methods
