ABSTRACT

BACKGROUND: Snakebite is a neglected problem with a high mortality in India. There are no simple clinical prognostic tools which can predict mortality in viper envenomings. We aimed to develop and validate a mortality-risk prediction score for patients of viper envenoming from Southern India. METHODS: We used clinical predictors from a prospective cohort of 248 patients with syndromic diagnosis of viper envenoming and had a positive 20-minute whole blood clotting test (WBCT 20) from a tertiary-care hospital in Puducherry, India. We applied multivariable logistic regression with backward elimination approach. External validation of this score was done among 140 patients from the same centre and its performance was assessed with concordance statistic and calibration plots. FINDINGS: The final model termed VENOMS from the term "Viper ENvenOming Mortality Score included 7 admission clinical parameters (recorded in the first 48 hours after bite): presence of overt bleeding manifestations, presence of capillary leak syndrome, haemoglobin <10 g/dL, bite to antivenom administration time > 6.5 h, systolic blood pressure < 100 mm Hg, urine output <20 mL/h in 24 h and female gender. The lowest possible VENOMS score of 0 predicted an in-hospital mortality risk of 0.06% while highest score of 12 predicted a mortality of 99.1%. The model had a concordance statistic of 0·86 (95% CI 0·79-0·94) in the validation cohort. Calibration plots indicated good agreement of predicted and observed outcomes. CONCLUSIONS: The VENOMS score is a good predictor of the mortality in viper envenoming in southern India where Russell's viper envenoming burden is high. The score may have potential applications in triaging patients and guiding management after further validation.

ABSTRACT

Snake bite is an important cause for acute kidney injury (AKI) in the tropics and the victims are often otherwise healthy young adults without conventional risk factors for chronic kidney disease (CKD). Available literature on long-term outcomes of AKI -snake envenomation is limited, with only two small retrospective studies with follow-up periods of two years or less. In a hospital-based prospective and retrospective follow-up study, all consecutive adult patients who developed AKI and discharged alive were recruited in the prospective group and for retrospective analysis, we retrieved medical records of patients hospitalized with snake bite from the digitized medical records. Clinical and biochemical characteristics during hospitalization and on follow-up were collected. We recruited 193 patients with snake bite and AKI in a prospective (140) and a retrospective (53) group. Of the 193 AKI patients, 162 (84%) had estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 at the time of discharge from hospital and at follow-up (n = 171) 29 (16.9%) had eGFR<60 mL/min/1.73 m2. Of the 116 patients with follow-up beyond one year, 30 (26%) had CKD. Overall 26 to 28% of patients went on to develop CKD depending on the duration of follow-up. Only very few (1.16%) patients progressed to ESRD. This is the largest follow-up study so far on snake bite-related AKI and provides further evidence that snake bite-associated AKI causes CKD on long-term follow-up. Older age, diabetes, severe AKI, and inadequate anti-snake venom administration were risk factors for the development of CKD on follow-up.

ABSTRACT

BACKGROUND: Prothrombotic factors have been correlated with vascular events in young patients, with recurrent strokes, and with venous thromboembolisms. However, their prevalence in adult strokes, in healthy populations, and in specific ethnic groups is not well defined. We investigated the association of prothrombotic factors with strokes in a South Indian Tamil population. METHODS: In this hospital-based cross-sectional study, plasma homocysteine (Hcys), protein C and protein S activity levels, activated protein C resistance (APCR) as a surrogate for factor V Leiden (FVL), fibrinogen, and antithrombin III (ATIII) were determined from 75 consecutive patients with ischemic stroke (IS), 25 with cortical venous thrombosis (CVT), and 75 healthy control participants. The Student t test or Mann-Whitney U test was used for comparing prothrombotic factor levels between the stroke and control groups. The χ2 or Fisher exact test was used for comparisons of proportions of thrombophilia and estimation of odds ratios. Mid-P correction was done for multiple estimations. RESULTS: Hcys levels in patients with IS were significantly higher compared with those in healthy control participants (P = 0.02). Proportions of ATIII deficiency and hyperfibrinogenemia were significantly higher in the IS group, and no healthy control participants had hyperfibrinogenemia. Protein C deficiency was more frequent in those with IS (17%; P < 8 × 10-5) and CVT (P < 10-7) compared with healthy control participants, and protein C activity levels (P = 0.016) were also significantly lower in patients with CVT. Other parameters had no significant associations with IS and CVT. The frequency of protein S deficiency was high in healthy control participants (60%) and in both patients with IS (45%; P = 0.1) and patients with CVT (48%; P = 0.4). No patients or control participants had abnormal APCR. CONCLUSIONS: In Tamilian participants, several prothrombotic factors were associated with IS. Protein C deficiency alone was associated with CVT. Replication of the pattern in genetically linked populations around the world may affect management of stroke in those populations.

ABSTRACT

Acute myeloid leukemia has a poor outcome because of early deaths, high relapse rate and financial constraints. Our hospital provides care free of cost and this study assesses the short term outcome of acute myeloid leukemia in adults. The study was done from September 2013 to May 2015. All patients above 18 years of age were included. Cytarabine infusion 100 mg/m2 daily for 7 days and Daunorubicin 60 mg/m2 daily for 3 days was used for induction chemotherapy followed by three cycles of high dose cytarabine as post-remission therapy. One hundred and two patients were included in the study. 48% were males. The median age was 41 years. There was an intention to treat in 84 patients. 13 patients died before chemotherapy and 71 patients (57 non AML M3) received induction chemotherapy. 82% of them had a Eastern Cooperative Oncology Group performance score of ≤ 2. 28 (of 57 non AML M3) patients were alive after post-remission therapy (with 39% deaths during induction phase) and 15 of them were in remission after a median follow up of nine months. The overall event free survival at the end of the study was 22% (16 out of 71). Altogether, 63 out of 84 patients had died. Sepsis was considered as the cause of death in 46% of the patients, but the isolation of causative organism was limited (20%). The treatment outcomes of AML are poor at our centre and the current standard of care needs a significant improvement.

ABSTRACT

BACKGROUND & OBJECTIVES: Although insulin resistance (IR) is a known complication in obesity, the physiological mechanisms linking IR with cardiometabolic risks in obesity have not been well studied. This study was conducted to assess the difference in cardiovascular (CV) risk profile in IR and non-IR (NIR) conditions, and contribution of IR to cardiometabolic risks in pre-obese and obese individuals. METHODS: Basal CV, blood pressure variability, autonomic function test and cardiometabolic parameters were recorded in pre-obese (n=86) and obese (n=77) individuals during 2012 and 2015. The association of altered cardiometabolic parameters with homeostatic model for IR (HOMA-IR) in pre-obese and obese groups and with baroreceptor sensitivity (BRS) in IR and NIR groups was calculated by appropriate statistical analysis. RESULTS: Decreased BRS, a known CV risk and cardiometabolic parameters were significant in IR (pre-obese and obese) group compared to the NIR group. Sympathovagal imbalance in the form of increased sympathetic and decreased parasympathetic activities was observed in individuals with IR. There was no significant difference in the level of independent contribution of HOMA-IR to cardiometabolic parameters in pre-obese and obese groups. Adiponectin and inflammatory markers had an independent contribution to BRS in IR group. INTERPRETATION & CONCLUSIONS: Findings of the present study demonstrated that the intensity of cardiometabolic derangements and CV risk were comparable between IR, pre-obese and obese individuals. Pro-inflammatory state, dyslipidaemia and hypoadiponectinaemia might contribute to CV risk in these individuals with IR. IR could possibly be the link between altered metabolic profile and increased CV risks in these individuals independent of the adiposity status.

ABSTRACT

BACKGROUND: Drug-drug interactions are a major source of adverse drug events (ADEs). Polypharmacy, age and the number of comorbid conditions are important predictors of adverse drug interactions. ADEs account for up to 5% of hospital admissions per year and an increase in the length of hospital stay. OBJECTIVE: To find the prevalence and predictors of potential drug-drug interactions (pDDIs) in patients admitted to the wards of an internal medicine department of a tertiary care hospital. METHOD: Patients admitted to internal medicine wards with prescriptions having more than one drug were selected. Demographic details including age, gender, number of comorbid conditions, number of drugs prescribed and the disease for which the patient was admitted were recorded in a case record form. Interactions were checked using Micromedex DrugReax software. RESULTS: A total of 939 patients were recruited for this study based on inclusion criteria. 433 prescriptions (46%) had one or more pDDIs, with a range of 1-13 drug interactions per prescription. A total of 1395 drug interactions were found, with 866 moderate drug interactions (62%), 435 major interactions (31.1%) and 89 minor interactions (6.3%). During the study period only three contraindicated drug combinations (0.2%) were recorded. A significant association (p<0.01) was found between the number of pDDIs and predictors, age and number of drugs. CONCLUSION: A total of 433 prescriptions (46%) had one or more pDDIs. Older patients and those prescribed >6 drugs are at major risk for occurrence of pDDIs. Moderate severity interactions were the highest number followed by major severity interactions.

ABSTRACT

BACKGROUND & OBJECTIVES: The optimal anti-snake venom (ASV) dose required to treat neurotoxic snake envenomation is not known. Low-dose ASV (national protocol: maximum dose 200 ml) may be as efficacious as the conventional regimen (100 ml six hourly till all symptoms disappear), but a direct comparison of the regimens is not available. The aim of this study was to test the efficacy of low-dose ASV regimen against the conventional high-dose regimen. METHODS: The clinical profile of 51 patients with neurotoxic snake envenomation was studied. Patients were treated with either the national protocol or the conventional protocol for ASV administration. The time to complete recovery of symptoms, duration of mechanical ventilation and total dose of ASV were compared. RESULTS: More patients were females (28 vs. 23) bitten in the early morning hours (2400-0600 h). Thirty nine of 51 (76.4%) patients required mechanical ventilation. In terms of progression of neuroparalysis, time to complete resolution of ptosis and occurrence of VAP and ASV reactions, there was no difference. Duration of mechanical ventilation was less with the national protocol (24 vs. 43.5 h). Significantly less amount of ASV was used with the national protocol (224 vs. 982 ml) per patient. There were no mortality or permanent neurological sequelae with either regimen. INTERPRETATION & CONCLUSIONS: In this preliminary study, it was found that the national ASV protocol was as effective as the conventional regimen for neurotoxic snake bites. However, the findings need to be tested in a larger randomized controlled trial for definitive conclusions.

ABSTRACT

INTRODUCTION: Inherited factor V deficiency / Owren's disease has varied clinical manifestations ranging from asymptomatic laboratory abnormalities to massive hemorrhage. The acquired form due to inhibitors following antibiotic therapy, infection, or surgery is less common, and spontaneous development of inhibitors is not known. CASE REPORT: An 18-year-old boy presented with bleeding axillary and groin ulcers. At the age of 15, due to recurrent epistaxis and gum bleed, he was diagnosed with acquired factor V deficiency with positive inhibitor screen and treated with fresh frozen plasma (FFP) transfusion and temporary azathioprine. Coagulation workup at his current presentation also revealed acquired factor V deficiency with presence of inhibitors. The tests were repeated after 6 weeks of intermittent FFP transfusion, and the differences observed included negative inhibitor screen and complete correction on mixing studies, but factor V level was 2%. DISCUSSION: Evidence of inhibitors at presentation favored acquired disease. However, younger age of onset, detection of inhibitors 1 year after first episode of self-regressing bleed, lack of identifiable triggers, and persistent bleeding with reduced factor levels after disappearance of inhibitors favored inherited factor V deficiency. CONCLUSION: In this case report, we have described an interesting case of severe inherited factor V deficiency with spontaneous appearance and disappearance of inhibitors exhibiting nonspecific factor inhibitory activity.

ABSTRACT

Procalcitonin has been found to be a good marker for the diagnosis of sepsis. However, data on procalcitonin levels to predict the clinical outcome in patients with sepsis are limited. The aim of our study was to estimate serum procalcitonin levels in patients with sepsis and to identify its relationship with the clinical outcome. This was a prospective observational study conducted on 112 patients with sepsis admitted to the medical wards and medical intensive care unit of a tertiary care teaching hospital. Serum procalcitonin was measured at baseline before antibiotic administration and on day 5. The clinical outcome studied was death or survival on day 28. Baseline mean serum procalcitonin was highest in patients with septic shock and lowest in patients having sepsis without organ dysfunction. Mean values of procalcitonin at baseline and on day 5 were significantly higher in non-survivors when compared with survivors. There was a significant difference in the change in procalcitonin levels from baseline to day 5 between survivors and non-survivors, with survivors having declining values on day 5 while non-survivors had increasing values from baseline. The baseline APACHE II and SOFA scores also showed a significant correlation with the baseline procalcitonin level. Declining values of procalcitonin therefore indicate a favourable clinical outcome in patients with sepsis.

ABSTRACT

Bleomycin-induced skin toxicity is a rare and unique complication. We report a 35-year-old man with nodular lymphocytic predominant Hodgkin's lymphoma, stage IVB, who was started on adriamycin, bleomycin, vinblastin and dacarbazine (ABVD) chemotherapy. He developed pruritic hyperpigmented, patchy skin lesions on the neck, back, chest and thighs after IA cycle of ABVD chemotherapy. Lesions were not typical flagellate rash but hyperpigmented, patchy and mildly pruritic lesions over the trunk and proximal extremities. Lesions increased with continuation of bleomycin and improved gradually after removing the drug from chemotherapy schedule. The patient was in complete remission after VI cycles of chemotherapy (AVD Regimen) and skin lesions healed with minimal residual hyperpigmentation.

ABSTRACT

INTRODUCTION: Lipid abnormalities and increase in inflammatory markers are common among patients with End Stage Renal Disease (ESRD) and it tends to persist/worsen even after initiating Intermittent Haemodialysis (IHD). The cardiovascular mortality and morbidity remains significantly high in this population. AIM: The present study was carried out to assess the pattern of lipid abnormality in our population and to find its association with inflammatory markers. MATERIALS AND METHODS: It was a cross-sectional, observational study on ESRD patients undergoing Haemodialysis (HD) in comparison with age and sex matched healthy individuals in a tertiary care hospital. About 40 adult male and female patients aged >18 years, undergoing chronic HD for more than 6 months were enrolled in Group A. Patients who were alcoholics, tobacco consumers and those on steroids and hypolipidemic drugs were excluded. Group B consisted of healthy, age and sex matched controls. Serum lipid profile, lipoprotein A, apolipoprotein A1, apolipoprotein B and apo B/A1 ratio, serum uric acid, homocysteine, hs-CRP and testosterone levels were estimated among patients undergoing intermittent HD and healthy individuals. Chi-square/Fisher's-exact test was used for comparing ratios. A p-value of <0.05 was considered statistically significant. RESULTS: The mean Total Cholesterol (TC), Low Density Lipoprotein (LDL) and Non-HDL High Density Lipoprotein cholesterol was significantly lower in HD patients as compared to control group with all the three parameters attaining statistical significance (p<0.005). The mean lipoprotein A level was significantly higher (p=0.037), while Apo A1 was found to be significantly lower (p=0.001) in patients receiving HD. Inflammatory markers like uric acid was high (p<0.005) and serum testotsterone level in male HD patient was significantly low (p<0.005). CONCLUSION: The mean values of traditional serum lipid profile remained lower in HD patients than the control group. The abnormalities in lipoprotein A and apolipoproteins were more pronounced in patients undergoing HD. The mean level of testosterone also was found to be lower in male patients receiving HD. Hence, estimation of lipoprotein A, apolipoproteins and inflammatory markers may serve as a potential tool in cardiovascular risk stratification.

ABSTRACT

BACKGROUND AND AIMS: Upper gastrointestinal symptoms are more prevalent among type 2 diabetes mellitus (T2DM) patients. The prevalence of delayed gastric emptying (GE) and factors predictive of it have not been studied in Indian T2DM patients and the present study aimed to study the same. METHODS: This hospital-based cross-sectional study involved adult (age between 18 and 65 years) outpatients with T2DM of ≥5-year duration. Measurements of GE of a labelled standardized solid rice idli meal by gastric emptying scintigraphy (GES), symptoms of delayed GE (by standardized questionnaire) and autonomic function by cardiovascular autonomic function tests (AFTs) were carried out. Thirty healthy subjects served as controls for GES and AFTs. RESULTS: One hundred and forty T2DM patients (age range: 32-65 years) were studied. Delayed GE was documented in ≈29 % (40/140) and rapid GE in 2 % (3/140) of T2DM patients. Univariate analysis showed significant positive association between delayed GE and duration of DM, body mass index (BMI), HbA1c, retinopathy, peripheral neuropathy, autonomic dysfunction and coronary artery disease (p < 0.05 for all). However, there was no significant correlation of age, sex, symptoms suggestive of gastroparesis and nephropathy with delayed GE. Hypoglycemic episodes were significantly more frequent in those with delayed GE (p < 0.05). Multiple logistic regression analysis revealed only BMI and HbA1c to be significant independent predictors of delayed GE. CONCLUSION: Presence and severity of symptoms of gastroparesis did not predict delayed GE. Delayed GE, irrespective of symptoms, was associated with microvascular and macrovascular diabetic complications and increased risk of hypoglycemic episodes. HbA1c and BMI were independent predictors of delayed GE.

ABSTRACT

T cell large granular lymphocytic leukemia is a clonal proliferation of cytotoxic large granular T cells positive for CD3 and CD8. It is a chronic lymphoproliferative disorder with an indolent course. Therapeutic options include observation and low dose chemotherapy. Rarely, they have an aggressive course. Such cases have expression of NK cell associated antigens like CD56 in the T cells. These cases require more aggressive therapy with acute lymphoblastic leukemia regimens. We report a case of fatal CD56 negative T cell large granular lymphocytic leukemia in a 38 year old lady.

ABSTRACT

Intravenous (IV) administration of iodinated contrast agents (ICAs) is frequently employed for image enhancement while performing radiographic studies such as computed tomography and angiography. Complications related to IV administration of ICAs such as immediate hypersensitivity reactions and nephrotoxicity are well-known. However, severe skin and soft tissue injuries and acute compartment syndrome resulting from contrast extravasation are rare. This is especially so with small volume extravasation of a low osmolar, nonionic ICA such as iohexol. Here, we report a 63-year-old woman who developed acute compartment syndrome of left hand following iohexol extravasation and had swelling, blistering, cutaneous and soft tissue necrosis. She underwent fasciotomy for acute compartment syndrome of hand and later surgical debridement of necrotic skin and soft tissues was carried out. Clinical pharmacology of ICAs, extravasation injuries following their IV administration, their management and measures to reduce them are discussed in brief.

ABSTRACT

OBJECTIVE: Though decreased baroreflex sensitivity (BRS), the predictor of cardiac morbidities and mortality has been reported in obesity, the mechanisms and metabolic biomarkers influencing BRS have not been studied. We aimed to assess the difference in cardiovascular (CV) risk profile in pre-obesity and obesity, and the contribution of body composition and cardiometabolic factors to CV risks in these two conditions. METHODS: Obesity indices, body composition, blood pressure variability and autonomic function test parameters were recorded in 223 subjects divided into controls (n=72), pre-obese (n=77) and obese (n=74) groups. Insulin resistance (HOMA-IR), atherogenic index (AI), leptin, adiponectin, inflammatory and oxidative stress parameters were measured. Association and independent contribution of altered cardiometabolic parameters with BRS were performed by Pearson's correlation and multiple regression analysis, respectively. RESULTS: BRS was significantly decreased in pre-obese and obese group compared to controls. Sympathovagal imbalance (SVI) in the form of increased sympathetic and decreased parasympathetic cardiac drives was observed in pre-obesity and obesity. There was significant difference in general markers of obesity (body mass index, and waist-to-hip ratio), between pre-obese and obese group, however no such difference was observed in body composition and cardiometabolic parameters between the two groups. AI, high sensitive C-reactive protein (hs-CRP) and ratio of basal metabolism to body fat (BM/BF) in pre-obese group, and AI, HOMA-IR, leptin, adiponectin, ratio of basal metabolism to body weight (BM/BW), BM/BF, inflammatory and oxidative stress markers in obese group had independent contribution to BRS. Among these metabolic biomarkers, BRS had maximum association with leptin (ß=0.532, p=0.000) in the obese group and hs-CRP (ß=0.445, p=0.022) in the pre-obese group. CONCLUSIONS: The present study demonstrates decreased BRS, an important marker of increased CV risk in pre-obesity and obesity. The intensity of cardiometabolic derangements and CV risk was comparable between pre-obese and obese subjects. BM/BF ratio appears to be a better marker of metabolic activity in pre-obesity and obesity. SVI and increased basal metabolism appear to be the physiological link between metabolic derangements and CV risks in both pre-obesity and obesity.

ABSTRACT

Neonicotinoid insecticides are considered to be less toxic to humans compared to older insecticides such as organophosphates, carbamates, pyrethroids, and organochlorine compounds. However,reports of severe human toxicity with neonicotinoids are emerging. Acute human thiacloprid poisoning and death as a result have not been reported in the literature so far. Here we report a case of thiacloprid poisoning resulting from deliberate ingestion in a 23-year-old man, manifesting with status epilepticus, respiratory paralysis,rhabdomyolysis, metabolic acidosis, and acute kidney injury (AKI), and ultimately giving rise to refractory shock and death. Thiacloprid can cause fatal human toxicity when ingested heavily, and absence of an effective antidote raises concern in this regard.

ABSTRACT

AIMS/INTRODUCTION: As reports show cardiovascular (CV) risks in first-degree relatives (FDR) of type 2 diabetics, and autonomic imbalance predisposing to CV risks, in the present study we have assessed the contribution of sympathovagal imbalance (SVI) to CV risks in these subjects. MATERIALS AND METHODS: Body mass index (BMI), waist-to-hip ratio (WHR), basal heart rate (BHR), blood pressure (BP), rate pressure product (RPP), and spectral indices of heart rate variability (HRV) were reordered and analyzed in FDR of type 2 diabetics (study group, n = 293) and in subjects with no family history of diabetes (control group, n = 405). RESULTS: The ratio of low-frequency (LF) to high-frequency (HF) power of HRV (LF-HF), a sensitive marker of SVI, was significantly increased (P < 0.001) in the study group compared with the control group. The SVI in the study group was due to concomitant sympathetic activation (increased LF) and vagal inhibition (decreased HF). In the study group, the LF-HF ratio was significantly correlated with BMI, WHR, BHR, BP and RPP. Multiple regression analysis showed an independent contribution of LF-HF to hypertension status (P = 0.000), and bivariate logistic regression showed significant prediction (odds ratio 2.16, confidence interval 1.130-5.115) of LF-HF to increased RPP, the marker of CV risk, in the study group. CONCLUSIONS: Sympathovagal imbalance in the form of increased sympathetic and decreased parasympathetic activity is present in FDR of type 2 diabetics. Increased resting heart rate, elevated hypertension status, decreased HRV and increased RPP in these subjects make them vulnerable to CV risks. SVI in these subjects contributes to CV risks independent of the degree of adiposity.

ABSTRACT

Pre-T cell acute lymphoblastic leukemia is a relatively rare leukemia. Twenty to 30 % of adult B cell leukemia cases are Philadelphia chromosome positive and it has a therapeutic and prognostic significance. Incidence and outcome of Ph+ T cell acute lymphoblastic leukemia (T cell ALL) is unknown. Only about 25 cases of de novo Ph+ T cell ALL and 44 cases of Ph+ T ALL in blastic phase of CML has been reported. Differentiation between Ph+ Pre-T ALL/LBL and T cell lymphoblastic crises of chronic myeloid leukemia may be difficult. We report a case of adult T cell ALL having Philadelphia chromosome as the cytogenetic abnormality. He was treated with acute lymphoblastic leukemia induction chemotherapy and Imatinib and achieved complete remission.
