Prognosis and long-term outcomes of acute kidney injury due to snake envenomation.

BACKGROUND: Snakebite is a common occupational hazard in tropical countries. To date, the literature on snakebite-related acute kidney injury (AKI) has been limited by retrospective study designs, lack of uniformity in case definitions of AKI and limited follow-up. This study aims to identify the in-hospital outcomes and long-term changes in kidney function that follow haemotoxic envenomation. METHODS: All adult patients admitted with AKI following haemotoxic envenomation from January 2016 to June 2017 were recruited and followed up until July 2018. Predictors of in-hospital mortality was assessed. Long-term follow-up data on kidney function were collected from survivors. RESULTS: In total, 184 patients with haemotoxic envenomation and AKI were recruited. The mean age of the subjects was 42.2 years [95% confidence interval (CI) 40.3-44.7]. The majority were male (71.2%). The mortality of patients with haemotoxic envenomation was 21.5%. The mortality was considerably higher in patients with Kidney Disease: Improving Global Outcomes (KDIGO) Stage 3 AKI [relative risk (RR) 4.45 (95% CI 1.14-17.42)] and those who met KDIGO urine output criteria [RR 20.45 (95% CI 2.84-147.23)]. A Cox regression model identified mechanical ventilation [odds ratio (OR) 5.59 (95% CI 2.90-10.81)], hypotension [OR 2.48 (95% CI 1.31-4.72)] and capillary leak syndrome [OR 2.02 (95% CI 1.05-3.88)] as independent predictors of mortality. Long-term follow-up data were available for 73 patients. A total of 21 patients (28.7%) developed adverse renal outcomes (glomerular filtration rate <60 mL/min/1.73 m2, urine albumin excretion >30 mg/g and new-onset hypertension or prehypertension). CONCLUSIONS: AKI resulting from snake envenomation is associated with considerable risk of mortality. The greater the AKI stage the greater the likelihood of mortality. One-third of patients with AKI developed long-term complications like chronic kidney disease, prehypertension and hypertension over the follow-up period.

Comparison of two Anti Snake Venom protocols in hemotoxic snake bite: A randomized trial.

The dose of Anti Snake Venom (ASV) in hemotoxic snake bite depends on the amount of venom injected and species of snake. All trials in South East Asia have studied different doses of ASV, wherein the ASV in high dose group itself was lower than the dose that is recommended in Indian National protocol. These studies favored low dose protocol, as there was no difference in mortality and morbidity between the groups. So, this study intended to assess the efficacy of National protocol in reducing morbidity and mortality in hemotoxic snake bite in comparison to current protocol followed in institution. This was an open label randomized trial of 140 hemotoxic snakebite patients. Group A received national protocol: initial dose of 100 ml followed by 100 ml 6th hourly till 20-min Whole Blood Clotting Time (20WBCT) was negative or 300 ml of ASV was given, whichever was earlier. Group B received 70 ml followed by 30 ml every 6th hourly until two consecutive 20WBCT were negative. There was no statistical difference in the amount of ASV required in both the groups. Mortality and acute kidney injury were higher in group A (statistically not significant), probably due to sicker patients in that group. There was no relapse of clotting time abnormality in both the groups. In a significant number of patients (12%), clotting time was persistently prolonged till death. We found that the use of National ASV dosing protocol did not decrease the mortality and morbidity.

Serum Procalcitonin Concentration and Its Relationship with Local Manifestations after Snakebites.

The local signs and symptoms following snakebites are similar to those of cellulitis caused by bacterial infections. This leads to empirical treatment with antibiotics, which however is not supported by evidence. Procalcitonin (PCT) is a biomarker with good diagnostic accuracy for bacterial infection. We studied serum PCT concentration in 100 patients aged 13 years or more, presenting to the hospital with significant local manifestations (crossing the joint proximal to the bitten wound) within 24 hours after snakebite. The extent and progression of local manifestations were monitored 12 hourly. Baseline PCT measurement was carried out for all patients and measurement was repeated 12 hourly only in those patients with progressive local manifestations. The median interqartile range PCT concentration did not differ significantly by the severity of local manifestation at presentation (Grade 2 = 0.28 [0.26-0.30]; Grade 3 = 0.28 [0.26-0.32]; Grade 4 = 0.27 [0.26-0.32] ng/mL; P = 0.15). Furthermore, we did not observe an increase in PCT concentration on serial estimation in those with progressive local manifestation (0.28, 0.29, and 0.29 ng/mL) over 36 hours. These observations suggest that the local manifestations following snakebites were not caused by bacterial infection.

Detection of Blastocystis in clinical stool specimens using three different methods and morphological examination in Jones' medium.

BACKGROUND: Blastocystis was identified almost a century ago, yet its biology and pathogenicity status in humans is obscure. Studies on Blastocystis in India are scanty and are mostly microscopy based. This study compared three detection modalities to determine their efficiency in the identification of Blastocystis in human feces. MATERIALS AND METHODS: A total of 279 stool samples were screened using microscopy, culture (Jones' medium), and polymerase chain reaction (PCR)-based methods. Among the three, PCR is considered the gold standard test for detection of Blastocystis, as it helps to authenticate the sensitivity, specificity, and kappa agreement obtained by the other two tests. The morphological features of Blastocystis were recorded at 24, 48, and 72 h. After positive morphological identification, ten samples were cultured on Löwenstein-Jensen (LJ) medium and Locke's egg slant medium. RESULTS: The sensitivity and specificity determined on the basis of microscopy were 36.2% and 99.4%, respectively. On the other hand, Jones' medium showed 67.6% sensitivity and 100% specificity. Further, we documented various morphological and reproductive features of Blastocystis using various staining techniques on cultures positive in Jones' medium. In addition, we also found that LJ medium was not equally efficacious as Jones' medium in assisting the growth of Blastocystis. CONCLUSIONS: Although molecular diagnosis is a necessary tool for understanding the true epidemiology of Blastocystis, in laboratories devoid of molecular detection facilities, stool microscopy in conjunction with stool culture on Jones' medium could serve as the best alternative tool for the detection of Blastocystis.

Stopping the effective non-fluoroquinolone antibiotics at day 7 vs continuing until day 14 in adults with acute pyelonephritis requiring hospitalization: A randomized non-inferiority trial.

OBJECTIVE: To evaluate whether stopping the effective antibiotic treatment following clinical improvement at Day 7 (Truncated treatment) would be non-inferior to continued treatment until Day 14 (Continued treatment) in patients with acute pyelonephritis (APN) requiring hospitalization treated with non-fluoroquinolone (non-FQ) antibiotics. METHODS: Hospitalized adult men and non-pregnant women with culture-confirmed APN were eligible for participation after they had clinically improved following empirical or culture-guided treatment with intravenous non-FQ antibiotic(s). We excluded patients with severe sepsis, abscesses, prostatitis, recurrent or catheter-associated urinary tract infection, or urinary tract obstruction. We randomized eligible patients on Day 7 of effective treatment and assessed them at Weeks 1 and 6 after treatment completion. The primary outcome was retreatment for recurrent urinary tract infection. The prespecified non-inferiority margin was 15%. RESULTS: Between March 17, 2015 and August 22, 2016, we randomly allocated 54 patients-27 patients in each arm. Twenty-four (44%) patients were male, and 26 (48%) had diabetes mellitus. Escherichia coli was the most common urinary isolate (47 [87%] patients); 36 (78%) were resistant to ciprofloxacin. In all, 41 (76%) patients received amikacin-based treatment. At the end of 6 weeks, no patient in the truncated treatment arm required retreatment, whereas 1 patient in the continued treatment arm was retreated. Difference (90% CI) in retreatment was -3.7% (-15.01% to 6.15%). Upper bound of the difference (6.15%) was below the prespecified limit, establishing non-inferiority of truncated treatment. Asymptomatic bacteriuria at Week 6 was similar between the two arms (3/24 vs. 3/26; P = 1.0). Patients in the truncated treatment arm had significantly shorter hospital stay (8 [7-10] vs. 14 [14-15] days; P < 0.001) and less antibiotic consumption per patient (8.4 ± 2.8 vs. 17.4 ± 8.3 DDDs; P < 0.001). CONCLUSION: Stopping the effective non-FQ antibiotics following clinical improvement at Day 7 is non-inferior to continued treatment until Day 14 in selected patients with APN requiring hospitalization.

Comparison of Hemoglobin A1c with Fasting and 2-h Plasma Glucose Tests for Diagnosis of Diabetes and Prediabetes among High-risk South Indians.

BACKGROUND: Glycosylated hemoglobin (HbA1c) has not been evaluated extensively for diabetes and prediabetes diagnosis and short-term variability of fasting plasma glucose (FPG), 2-h PG post-75 g glucose load (2 hPG) and HbA1c has not been studied among Indians. OBJECTIVES: The study aimed to compare the sensitivity of HbA1c, FPG and 2 hPG for diabetes and prediabetes diagnosis as per the American Diabetes Association criteria, assess short-term variability of three tests and determine optimal HbA1c cutoffs for diabetes and prediabetes diagnosis among high-risk south Indians. METHODS: This diagnostic accuracy study, conducted at a tertiary care teaching hospital located in South India, enrolled 332 adults at high risk for diabetes and subjected them to testing (FPG, 2 hPG, and HbA1c) twice at 2-3 weeks interval. Sensitivity of three tests for diagnosing diabetes and prediabetes was determined based on the final diagnosis of normoglycemia/prediabetes/diabetes made with six test results for each participant. Optimal HbA1c cutoffs for diabetes and prediabetes were determined based on the final diagnosis of glycemic status made with four test results of FPG and 2 hPG. RESULTS: FPG, 2 hPG, and HbA1c, at American Diabetes Association recommended values, had sensitivity of 84.4%, 97%, and 93.8% respectively for diabetes diagnosis. HbA1c had lowest short-term variability (CVw = 1.6%). Receiver operating characteristic curve plotted with mean (of two values) HbA1c for each participant showed optimal HbA1c cutoffs of 6.5% for diabetes (area under curve [AUC] =0.990, sensitivity = 95.8%, specificity = 96.2%, accuracy = 95.2%) and 5.9% for prediabetes (AUC = 0.893, sensitivity = 84.3%, specificity = 80%, accuracy = 75.6%) diagnosis respectively. HbA1c <5.6% had 100% negative predictive value to exclude prediabetes/diabetes. CONCLUSIONS: HbA1c ≥6.5% is a convenient and reliable alternative to plasma glucose tests to diagnose diabetes among high-risk South Indians. HbA1c ≥5.9% is optimal for prediabetes diagnosis and value <5.6% excludes prediabetes/diabetes.Abbreviations used in the manuscript: ADA: American Diabetes Association, AUC: Area under curve, CVw: Within-person coefficient of variation, FPG: Fasting plasma glucose, 2 hPG: Two-hour plasma glucose post-75 g oral glucose load, HbA1c: Glycosylated haemoglobin, IFG: Impaired fasting glucose, IGT: Impaired glucose tolerance, NPV: Negative predictive value, PPV: Positive predictive value; PG: Plasma glucose, ROC: Receiver operating characteristic.

Primary Intestinal Lymphangiectasia (Waldmann's Disease) Presenting with Chylous Effusions in a 15-Year-Old.

Primary Intestinal Lymphangiectasia (PIL) is a rare disease of unknown aetiology which presents in the paediatric age group with anasarca, diarrhoea, hypoproteinaemia, lymphoedema and chylous effusions. Tuberculosis, filariasis, chest trauma, malignancies and haematological disorders usually contribute to most cases of secondary lymphangiectasia and chylous effusions. We hereby describe a case of PIL presenting with chylous effusions which remained undiagnosed for eight years.

Healthcare Associated Infections in a Resource Limited Setting.

INTRODUCTION: Health Care associated Infections (HAI) are the most common complications affecting the hospitalized patients. HAI are more common in developing and under developed countries. However, there are no systematic surveillance programs in these countries. AIM: To find out the burden, predisposing factors and multidrug resistant organisms causing HAI in a resource limited setting. MATERIALS AND METHODS: This prospective observational study was done at Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER). Patients aged 13 years or more with stay of more than 48 hours in a 16 bedded Medical Intensive Care Unit (MICU) between November 2011 and April 2013 were included in the study. Patients were prospectively followed up till discharge or death for the development of HAI. Device associated HAI like Ventilator Associated Pneumonia (VAP), Catheter Related-Blood Stream Infection (CR-BSI) and Catheter Associated-Urinary Tract Infections (CA-UTI) were studied. Standard laboratory methods were used for identification of microorganisms causing HAI and to test their antibiotic sensitivity. RESULTS: A total of 346 patients were included in the study with median age of 38 years. Common indications for admission to Medical Intensive Care Unit (MICU) were poisoning (31.5%); neurological illness (23.4%) like Guillian-Barre syndrome, tetanus, meningitis, encephalitis; respiratory illness (14.5%) like pneumonia, acute respiratory distress syndrome and tropical infections (7.2%) like malaria, scrub typhus, leptospirosis. Fifty percent (174/346) patients developed one or more HAI with VAP being the most common. The rates of HAI per 1000 device days for VAP, CR-BSI, CA-UTI were 72.56, 3.98 and 12.4, respectively. Acinetobacter baumannii was the most common organism associated with HAI. Multidrug resistance was seen in 74% of the isolates. CONCLUSION: The burden of HAI, especially with MDR organisms, in resource constrained setting like ours is alarming. There is urgent need for infection control and monitoring system to reduce HAI.

Curcumin inhibits hyperlipidemia and hepatic fat accumulation in high-fructose-fed male Wistar rats.

CONTEXT: Curcumin, an active principal of Curcuma longa Linn. (Zingiberaceae), has potent antioxidant and anti-inflammatory properties. OBJECTIVES: This study investigated the effects of curcumin on hyperlipidemia and hepatic steatosis in high-fructose-fed Wistar rats. MATERIALS AND METHODS: Forty male Wistar rats were divided into four groups with 10 rats in each. Two groups were fed with standard rodent diet and the other two with 60% high-fructose diet for 10 weeks. Curcumin (200 mg/kg body weight) was administered along with the diets simultaneously to each of the aforementioned diet groups. After 10 weeks of experiment, blood samples were collected from tail vein. Liver, adipose and epididymal tissues were collected after sacrifice of the animals and stored for further analyses. RESULTS: Administration of curcumin reduced body weight (280.6 ± 7.4 g), liver weight (2.5 ± 0.2 g/100 g BW), adipose weight (1.4 ± 0.3 g/100 g BW), plasma levels of TAG (86.1 ± 13.5 mg/dL), VLDL-C (17.2 ± 2.7 mg/dL), lipid ratios and increased HDL-C (28.4 ± 4.5 mg/dL) in fructose-fed rats. Curcumin supplementation significantly lowered TAG content and decreased the protein expression of LXR-α (43%) and SREBP1c (59%) in the liver. Furthermore, curcumin suppressed the expression of lipogenic enzymes, ACLY (95%), ACC (50%) and FAS (77%) in rats fed with high-fructose diet. No significant change was found in the expression of PPAR-α. DISCUSSION AND CONCLUSION: Curcumin prevented the high-fructose induced hyperlipidemia and hepatic steatosis.

Preventive effect of curcumin on inflammation, oxidative stress and insulin resistance in high-fat fed obese rats.

BACKGROUND: The present study investigated the beneficial effects of curcumin on inflammation, oxidative stress and insulin resistance in high-fat fed male Wistar rats. METHODS: Five-month-old male Wistar rats (n=20) were divided into two groups (10 rats in each group). Among the two groups, one group received 30 % high-fat diet (HFD) and another group received 30 % HFD with curcumin (200 mg/kg body weight). Food intake, body weight and biochemical parameters were measured at the beginning and at the end of the study. After 10 weeks, oxidative stress parameters in skeletal muscle and hepatic triacylglycerol (TAG) content were estimated. Histological examinations of the liver samples were performed at the end of the experiment. RESULTS: High-fat feeding caused increase in body weight, liver and adipose tissue mass. Rats fed with HFD showed increased levels of fasting plasma glucose, insulin, Homeostasis Model Assessment for Insulin resistance (HOMA-IR), total cholesterol (TC), TAG, very low density lipoprotein cholesterol (VLDL-c) and decreased high-density lipoprotein cholesterol (HDL-c). There was also increase in the plasma inflammatory markers [tumor necrosis factor-α (TNF-α), C-reactive protein (CRP)] and skeletal muscle oxidative stress parameters [malondialdehyde (MDA), total oxidant status (TOS)] in these rats. In addition, high-fat feeding increased liver TAG content and caused fat accumulation in the liver. Treatment with curcumin significantly reduced body weight, relative organ weights (liver, adipose tissue), glucose, insulin and HOMA-IR. Curcumin supplementation decreased plasma levels of TC, TAG, VLDL-c, TNF-α and increased HDL-c. Administration of curcumin also reduced MDA, TOS in skeletal muscle, hepatic TAG content and liver fat deposition. CONCLUSIONS: Curcumin supplementation improved HFD-induced dyslipidemia, oxidative stress, inflammation and insulin resistance.

Curcumin prevents inflammatory response, oxidative stress and insulin resistance in high fructose fed male Wistar rats: Potential role of serine kinases.

Emerging evidence suggests that high fructose consumption may be a potentially important factor responsible for the rising incidence of insulin resistance and diabetes worldwide. The present study investigated the preventive effect of curcumin on inflammation, oxidative stress and insulin resistance in high fructose fed male Wistar rats at the molecular level. Fructose feeding for 10 weeks caused oxidative stress, inflammation and insulin resistance. Curcumin treatment attenuated the insulin resistance by decreasing IRS-1 serine phosphorylation and increasing IRS-1 tyrosine phosphorylation in the skeletal muscle of high fructose fed rats. It also attenuated hyperinsulinemia, glucose intolerance and HOMA-IR level. Curcumin administration lowered tumor necrosis factor alpha (TNF-α), C reactive protein (CRP) levels and downregulated the protein expression of cyclo-oxygenase 2 (COX-2), protein kinase theta (PKCθ). In addition, inhibitor κB alpha (IκBα) degradation was prevented by curcumin supplementation. Treatment with curcumin inhibited the rise of malondialdehyde (MDA), total oxidant status (TOS) and suppressed the protein expression of extracellular kinase ½ (ERK ½), p38 in the skeletal muscle of fructose fed rats. Further, it enhanced Glutathione Peroxidase (GPx) activity in the muscle of fructose fed rats. At the molecular level, curcumin inhibited the activation of stress sensitive kinases and inflammatory cascades. Our findings conclude that curcumin attenuated glucose intolerance and insulin resistance through its antioxidant and anti-inflammatory effects. Thus, we suggest the use of curcumin as a therapeutic adjuvant in the management of diabetes, obesity and their associated complications.

Case-Mix, Care Processes, and Outcomes in Medically-Ill Patients Receiving Mechanical Ventilation in a Low-Resource Setting from Southern India: A Prospective Clinical Case Series.

BACKGROUND: Mechanical ventilation is a resource intensive organ support treatment, and historical studies from low-resource settings had reported a high mortality. We aimed to study the outcomes in patients receiving mechanical ventilation in a contemporary low-resource setting. METHODS: We prospectively studied the characteristics and outcomes (disease-related, mechanical ventilation-related, and process of care-related) in 237 adults mechanically ventilated for a medical illness at a teaching hospital in southern India during February 2011 to August 2012. Vital status of patients discharged from hospital was ascertained on Day 90 or later. RESULTS: Mean age of the patients was 40 ± 17 years; 140 (51%) were men. Poisoning and envenomation accounted for 98 (41%) of 237 admissions. In total, 87 (37%) patients died in-hospital; 16 (7%) died after discharge; 115 (49%) were alive at 90-day assessment; and 19 (8%) were lost to follow-up. Weaning was attempted in 171 (72%) patients; most patients (78 of 99 [79%]) failing the first attempt could be weaned off. Prolonged mechanical ventilation was required in 20 (8%) patients. Adherence to head-end elevation and deep vein thrombosis prophylaxis were 164 (69%) and 147 (62%) respectively. Risk of nosocomial infections particularly ventilator-associated pneumonia was high (57.2 per 1,000 ventilator-days). Higher APACHE II score quartiles (adjusted HR [95% CI] quartile 2, 2.65 [1.19-5.89]; quartile 3, 2.98 [1.24-7.15]; quartile 4, 5.78 [2.45-13.60]), and new-onset organ failure (2.98 [1.94-4.56]) were independently associated with the risk of death. Patients with poisoning had higher risk of reintubation (43% vs. 20%; P = 0.001) and ventilator-associated pneumonia (75% vs. 53%; P = 0.001). But, their mortality was significantly lower compared to the rest (24% vs. 44%; P = 0.002). CONCLUSIONS: The case-mix considerably differs from other settings. Mortality in this low-resource setting is similar to high-resource settings. But, further improvements in care processes and prevention of nosocomial infections are required.

Acalculous pyelonephritis and cholecystitis occurring simultaneously in a diabetic patient on sitagliptin therapy.

Dipeptidyl peptidase-4 (DPP-4) inhibitors are a new class of anti-diabetic drugs. They control both fasting and postprandial hyperglycemia by inhibiting degradation of incretin hormones, such as, glucagon-like peptide-1(GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Sitagliptin is the first DPP-4 inhibitor to be marketed in India. In addition to its glucose lowering effect, it also suppresses immunity resulting in various infections in a diabetes patient. Here, we describe the simultaneous development of two infections (acalculous pyelonephritis and cholecystitis) in a postmenopausal female patient, well-controlled on sitagliptin-based anti-diabetic therapy.

Curcumin Attenuates Oxidative Stress and Activation of Redox-Sensitive Kinases in High Fructose- and High-Fat-Fed Male Wistar Rats.

The present study was carried out to investigate the effects of curcumin on oxidative stress and redox-sensitive kinases in high fructose- and high-fat-fed rats. Sixty rats were randomly divided into six groups with ten animals each. Rats were fed with a standard rodent diet, high fructose diet (60%), and high-fat diet (30%). Curcumin was administered to control, high fructose and high fat diet groups for ten weeks. At the end of the study, body weight and blood glucose levels were measured. The antioxidant enzymes GSH (reduced glutathione), GPx (glutathione peroxidase), and catalase activities were estimated in the blood. MDA, TAS, and TOS were estimated in the plasma, liver, and kidney. Curcumin treatment decreased body weight and blood glucose levels in the rats fed with fructose and high-fat diet. Antioxidant enzymes and plasma TAS were significantly improved by curcumin treatment in high fructose-fed rats, whereas in high-fat-fed rats, there was an increase only in the GPx activity. Curcumin significantly attenuated the elevation of plasma MDA and TOS in both diet groups. Hepatic MDA and TOS were found to be decreased upon curcumin supplementation in both diet groups, whereas a decrease in the renal MDA levels was observed only in fructose-treated rats, not in fat-fed rats. Curcumin treatment elevated liver TAS in rats fed only with the fructose-rich diet. Curcumin showed a significant decrease in the oxidative stress index (OSI) in plasma, liver, and kidney tissues in both diet groups. ERK phosphorylation was significantly decreased in both diet groups by curcumin treatment. Similarly, curcumin reduced the phosphorylation of p38 MAPK only in the high fructose-fed rats, not in the high-fat-fed rats. No significant changes were found in JNK phosphorylation in both diet groups. Thus, curcumin may be effective in the management of diet-induced oxidative stress and could be explored as a therapeutic adjuvant against complications associated with obesity and diabetes.

Gender specific association of endothelial nitric oxide synthase gene (Glu298Asp) polymorphism with essential hypertension in a south Indian population.

BACKGROUND: Endothelial derived nitric oxide (NO) plays a major role in blood pressure regulation. The role of missense variant eNOS-Glu298Asp has been demonstrated by many studies with conflicting results. Our objective was to investigate the association of eNOS gene polymorphism with essential hypertension in a south Indian population. METHODS: We carried out a case control study in 438 hypertensive patients and 444 healthy control subjects in a homogenous population. Genotyping was done by PCR-RFLP method. Multiple logistic regression analysis was used to detect the association between genotype and hypertension. RESULTS: The homozygous variant genotype Asp298Asp was significantly associated with hypertension (odds ratio 2.4; 95% CI, 1.23-5.0, p<0.01). Gender specific analysis showed both the heterozygous (odds ratio, 2.0; 95% CI, 1.3-2.9, p<0.01) and homozygous variants (odds ratio, 7.9; 95% CI, 2.0-4.1, p<0.001) were positively associated with hypertension in females. The variant allele Asp was higher in female hypertensives when compared to male hypertensive cases (22% vs. 16%). CONCLUSION: The eNOS gene polymorphism is a candidate gene for hypertension and the association to be gender specific with respect to females in a south Indian Tamilian population.
