RESUMEN

BACKGROUND AND AIMS: Circulating levels of von Willebrand factor (vWF) predict mortality in patients with cirrhosis. We hypothesized that systemic inflammation in acute-on-chronic liver failure (ACLF) will stimulate endothelium, increase vWF levels, and promote platelet microthrombi causing organ failure. METHODS: In this prospective study, we correlated plasma vWF levels with organ failure, liver disease severity, sepsis, and systemic inflammatory response syndrome (SIRS) and also analyzed if vWF levels predicted in-hospital composite poor outcome (i.e. death/discharged in terminal condition/liver transplantation) in consecutive ACLF patients. RESULTS: Twenty-one of the 50 ACLF patients studied had composite poor outcome. ACLF patients had markedly elevated vWF antigen and activity (sevenfold and fivefold median increase, respectively) on days 1 and 3. Median ratio of vWF to a disintegrin and metalloprotease with thrombospondin type 1 motif, member 13 (ADAMTS13) activity on day 1 was significantly higher in ACLF patients (11.2) compared to 20 compensated cirrhosis patients (3.3) and healthy volunteers (0.9). On day 1, area under ROC curve (AUROC) to predict composite poor outcome of hospital stay for ACLF patients for vWF antigen, vWF activity, and model for end-stage liver disease (MELD) score were 0.63, 0.68, and 0.74, respectively. vWF activity correlated better with liver disease severity (MELD score, ACLF grade) and organ failure (Sequential Organ Failure Assessment [SOFA] score) than vWF antigen; in contrast, neither vWF antigen nor activity correlated with platelet count, sepsis, or SIRS. CONCLUSIONS: vWF levels are markedly elevated, correlate with organ failure, and predict in-hospital survival in ACLF patients. This data provides a mechanistic basis for postulating that vWF-reducing treatments such as plasma exchange may benefit ACLF patients.

RESUMEN

Portosystemic myelopathy is an unusual complication in patients with chronic liver disease with hepatic encephalopathy and portosystemic shunts. Here we present a case of 35-year-old male patient who presented to us with difficulty in walking and progressive stiffness in both lower limbs for two months. He had undergone splenectomy with distal splenorenal shunt 20 years back. On physical examination, he had spasticity in both lower limbs of grade 3, with minimal pyramidal weakness in lower limbs, brisk knee and ankle jerks. The plantar response was extensor. Upper limb examination was normal. On investigations, he had hypoalbuminemia, hyperbilirubinemia, increased plasma ammonia levels. Contrast enhanced CT scan abdomen revealed dilated splenorenal shunt and MRI spine showed no spinal cord compression. Electromyoneurogram was also normal. Spastic paraparesis due to portosystemic shunts was diagnosed. Liver transplantation can reverse the myelopathy only in earlier stages, hence early and accurate diagnosis is important.

RESUMEN

UNLABELLED: Drug-induced liver injury (DILI) is rare in children and adolescents, and, consequently, data are remarkably limited. We analyzed the causes, clinical and biochemical features, natural history, and outcomes of children with DILI. Consecutive children with DILI from 1997 to 2004 (retrospective) and 2005 to 2010 (prospective) were studied based on standard criteria for DILI. Thirty-nine children constituted 8.7% of 450 cases of DILI. There were 22 boys and 17 girls. Median age was 16 years (range, 2.6-17). Combination antituberculous drugs were the most common cause (n = 22), followed by the anticonvulsants, phenytoin (n = 10) and carbamazepine (n = 6). All of the 16 children (41%) who developed hypersensitivity features, such as skin rashes, fever, lymphadenopathy, and/or eosinophilia, including the 3 with Stevens-Johnson syndrome, survived. Those with hypersensitivity presented earlier (24.5 versus 35 days; P = 0.24) had less severe disease (MELD, 16 versus 29; P = 0.01) and had no mortality (0/16 versus 12/23; P < 0.001), compared to those without hypersensitivity. The 12 fatalities were largely the result of antituberculous DILI (n = 11). The presence of encephalopathy and ascites were associated with mortality, along with hyperbilirubinemia, high international normalized ratio, and serum creatinine. According to the Roussel Uclaf Causality Assessment Method, 18 were highly probable, 14 probable, and 7 possible. Thirty-two children were hospitalized. CONCLUSION: DILI is not uncommon in children and accounts for 8.7% of all patients with DILI. Antituberculous drugs and anticonvulsants are the leading causes of DILI in India. Overall mortality is high (30.7%), largely accounted by antituberculous drugs. Children with DILI and hypersensitivity features present early, have less severe disease, and, consequently, a better prognosis, compared to those without, and are often associated with anticonvulsants or sulfonamides.

RESUMEN

BACKGROUND: Assessing body image self-perception has used BMI as an indicator of nutritional status. The visual analogue scale is a highly effective instrument for assessing people's level of dissatisfaction with their body weight while evaluating the perceptual component of body image. OBJECTIVE: By knowing body mass index of female medical students, to find out their pattern of body image perception and any attempts done to change their weight. MATERIALS AND METHODS: All the students residing in MBBS ladies hostel were included in this study and a questionnaire regarding body image perception, diet, physical activity and attempts to change weight was instituted. Their responses were collected, tabulated, analyzed and interpreted. RESULTS: Among 147 study subjects, according to BMI, 25(17%) were undernourished while 111(75.5%) and 11(7.5%) were normally nourished and overweight respectively. 35(23.8%) of the subjects felt they were lean, 95(64.6%) felt they were normal and 17(11.6%) felt they were overweight. Regarding image satisfaction, 98(66.7%) of them were satisfied with their image and out of 49 who were not satisfied 30 (20.4 %) wanted to reduce weight. Skipping meals was practiced by 42 (28.6%) of subjects. CONCLUSION: About 75.5% of the study group were having normal BMI. Most of them perceived their image correctly regarding to their weight. Most of the underweight and all overweight females were not satisfied. Underweight females preferred to gain weight and overweight females preferred to lose weight.

RESUMEN

We report preliminary results from an ongoing series of experiments on lifespan extension by appropriately modified Ayurvedic rasayanas in animal models. Here data are presented indicating lifespan extensions of 51-55% (up to 70-95% in the pilot experiment) in a standard strain of Drosophila melanogaster (Oregon-K) using a standard rasayana (Ayurvedic herbal formulation for life-extension) suitably adapted for insects. In a first experiment, two groups of 20 unmated D. melanogaster strain Oregon-K kept at 22°C received either rasayana or standard yeast diet; days of death were recorded. Another experiment investigated possible sex differences; equal sized (N = 30) groups of similar males, females, and controls were compared. Life lengths of all controls were in the strain's usual range: in Experiment 1, control life lengths were minimum 40 to maximum 53 days; experimental group figures were 81-91 days; groups were completely separated, experimental group minimum life length being 28 days more than control group maximum life length, i.e., about 2.5 full distribution widths - a sign test for the null hypothesis yields p < 2(-20), i.e., 10(-6) as maximum p. Experiment 2 found no differences between life lengths of males and females; but the maximum life length of 30 controls (60 days in males and 66 days in females) was once again far shorter than the minimum life length of the 60 in the two experimental groups, strengthening the findings of Experiment 1. Despite group sizes being relatively small, results are conclusive: the rasayanas in question increase D. melanogaster strain Oregon-K life length. The complexity of the formulation suggests that multiple mechanisms are involved - worth further investigation.

RESUMEN

The Global Alliance for the Elimination of Lymphatic Filariasis (GAELF) has recommended exploring local health traditions of skin care and a low cost treatment paradigm for rural communities has been proposed by Vaqas and Ryan. Our case study incorporates these promising treatments for use in treating filariasis in rural communities. Patients having lymphedema of one or both lower limbs (skin: normal, thickened or with trophic/warty changes) received treatment components from ayurveda, yoga and biomedicine simultaneously: including soap wash, phanta soaking, Indian manual lymph drainage (IMLD), pre- and post-IMLD yoga exercises, and compression using bandages for 194 days, along with diet restrictions and oral herbal medicines indicated for "elephantiasis" in Ayurveda. Entry points when infected were treated with biomedical drugs. The study was conducted in the reverse pharmacology design. 112 patients and 149 lower limbs completed 194 days of treatment during 2003-2006. Significant improvements were observed in the limb circumference measurements and the frequency of acute dermatolymphangioadenitis, use of preventive antibiotics, and reduction in the number of entry points were also improved. The objective to obtain significant benefit for a common problem using locally available, sustainable and affordable means has been achieved. It has not been our purpose to show that the regimen employed is better than another but the results do pose the question--"Are there components of Ayurvedic medicine that deserve further study?" It is important to understand that the regimen has been delivered mostly at home and that participants we have treated, representing a population suffering from a common problem, have not had access to effective conservative therapy that is culturally acceptable, safe, and efficacious.

RESUMEN

A community based longitudinal study was conducted in Malpe, a coastal village of Udupi district, Karnataka state, to investigate acute respiratory infections (ARI) in children. A cohort of 91 children under 3 years of age were followed up for 1 year, leading to 2047 fortnightly observation. On an average every child had 11.3 months of follow up. The overall incidence of ARI was 6.42 episodes per child per year. On an average each episode lasted for 5.06 days. Mean duration of ARI during one year was 32.5 days per child. Most of the ARI episodes in children (91.3%) were of simple Cough & Cold (no pneumonia). However, 8.2% developed pneumonia and only 0.51% had severe pneumonia. Incidence of ARI was almost same in male and female children. There was no significant difference in incidence among various age groups. But the incidence of pneumonia was significantly higher among infants (p<0.00002). Children of poor housing with smoke producing conditions suffered more frequently (p,002).

RESUMEN

The profiles of patients with fulminant hepatic failure (FHF) from developing countries have not been reported earlier. The current study was conducted prospectively, at a single tertiary care center in India, to document the demographic and clinical characteristics, natural course, and causative profile of patients with FHF as well as to define simple prognostic markers in these patients. Four hundred twenty-three consecutive patients with FHF admitted from January 1987 to June 1993 were included in the study. Each patient's serum was tested for various hepatotropic viruses. Univariate Cox's regression for 28 variables, multivariate Cox's proportional hazard regression, stepwise logistic regression, and Kaplan-Meier survival analysis were done to identify independent predictors of outcome at admission. All patients presented with encephalopathy within 4 weeks of onset of symptoms. Hepatotropic viruses were the likely cause in most of these patients. Hepatitis A (HAV), hepatitis B (HBV), hepatitis D (HDV) viruses, and antitubercular drugs could be implicated as the cause of FHF in 1.7% (n= 7), 28% (n= 117), 3.8% (n= 16), and 4.5% (n= 19) patients, respectively. In the remaining 62% (n= 264) of patients the serological evidence of HAV, HBV, or HDV infection was lacking, and none of them had ingested hepatotoxins. FHF was presumed to be caused by non-A, non-B virus(es) infection. Sera of 50 patients from the latter group were tested for hepatitis E virus (HEV) RNA and HCV RNA. In 31 (62%), HEV could be implicated as the causative agent, and isolated HCV RNA could be detected in 7 (19%). Two hundred eighty eight (66%) patients died. Approximately 75% of those who died did so within 72 hours of hospitalisation. One quarter of the female patients with FHF were pregnant. Mortality among pregnant females, nonpregnant females, and male patients with FHF was similar (P > .1). Univariate analysis showed that age, size of the liver assessed by percussion, grade of coma, presence of clinical features of cerebral edema, presence of infection, serum bilirubin, and prothrombin time prolongation over controls at admission were related to survival (P < .01). The rapidity of onset of encephalopathy and cause of FHF did not influence the outcome. Cox's proportional hazard regression showed age > or = 40 years, presence of cerebral edema, serum bilirubin > or = 15 mg/dL, and prothrombin time prolongation of 25 seconds or more over controls were independent predictors of outcome. Ninety-three percent of the patients with three or more of the above prognostic markers died. The sensitivity, specificity, positive predictive value, and the negative predictive value of the presence of three or more of these prognostic factors for mortality was 93%, 80%, 86%, and 89.5%, respectively, with a diagnostic accuracy of 87.3%. We conclude that most of our patients with FHF might have been caused by hepatotropic viral infection, and non-A, non-B virus(es) seems to be the dominant hepatotropic viral infection among these patients. They presented with encephalopathy within 4 weeks of the onset of symptoms. Pregnancy, cause, and rapidity of onset of encephalopathy did not influence survival. The prognostic model developed in the current study is simple and can be performed at admission.
