September-October 2016, 48(5):522-525
DOI:10.4103/0253-7613.190729  PMID:27721537
Objectives: To compare the efficacy and safety of febuxostat and allopurinol in pyrazinamide (PZA)-induced hyperuricemia in patients taking antitubercular therapy (ATT). Methods: This randomized controlled study was conducted at a tertiary care teaching institute of Rajasthan in all the sputum-positive tubercular patients aged between 18 and 65 years of either sex. Serum uric acid level was monitored at 0 th , 2 nd , 4 th , 6 th , and 8 th week of ATT. Patients whose uric acid level was found to be increased at 2 nd week were finally recruited in the study. Ninety patients who developed hyperuricemia due to ATT were divided randomly into three groups (Group A - febuxostat, Group B - allopurinol, and Group C - control) of thirty patients each. Mean serum uric acid levels were calculated at all the weeks in all the groups, and serum uric acid levels were compared by applying student's t-test and ANOVA. Results: Mean serum uric acid level decreased from 10.698 mg/dl (at 2 nd week) to 7.846 mg/dl (at 8 th week) in Group A and from 11.34 mg/dl (at 2 nd week) to 7.280 mg/dl (at 8 th week) in Group B. Numbers of adverse events encountered across both the treatment groups were same with both the drugs. Conclusion: Allopurinol and febuxostat were equally efficacious in lowering PZA induced raised serum uric acid level in tubercular patients, and it was possible to continue ATT without withdrawing PZA.

DOI:10.4103/0253-7613.190760  PMID:27721548
Objectives: To study medicine prescribing pattern for chronic kidney disease (CKD) patients on maintenance hemodialysis. Materials and Methods: This prospective observational study was conducted in hemodialysis unit of a teaching hospital with adult CKD patients on maintenance hemodialysis. Patients' clinical profile, drug-use pattern, and medication-related problem data were captured in a structured case report form and the data were analyzed descriptively. Adherence level was assessed by Morisky Medication-Taking Adherence Scale 4-item. Results: Data from 100 patients recruited over 6 months have been analyzed. The median (interquartile range [IQR]) age was 51 (42-57) years; 57% were male, mean [standard deviation (SD)] urea level was 160.11 (70.32) mg/dL, mean (SD) creatinine level was 8.73 (5.29) mg/dL. A large number (46%) were suffering from diabetic nephropathy. The common comorbidities were anemia (89%) followed by hypertension (85%). The median (IQR) number of drugs per prescription was 10 (9-13), with the bulk being cardiovascular drugs (23.41%) followed by gastrointestinal drugs (15.76%) and vitamins (12.29%). The median (IQR) number of potential drug-drug interaction per prescription was 2 (2-3). The incidence of adverse drug reactions (ADRs) was 46% with hyponatremia being most common (32%), followed by hypoglycemia (16%) and hypokalemia (10%). Adherence level was low in the majority (64%) of patients. Conclusions: There is a high incidence of polypharmacy along with significant medication-related problems such as high drug-drug interactions/prescription, high incidence of ADRs, and low adherence.

Sachin Kumar, Sakshi Bajaj, Ramesh Babu Bodla
September-October 2016, 48(5):481-486
DOI:10.4103/0253-7613.190716  PMID:27721530
Cancer, a group of diseases of unregulated cell proliferation, is a leading cause of death worldwide. More than 80% of compounds which have shown promising effects in preclinical studies could not get through Phase II of clinical trials. Such high attrition rate is due to improper or selective use of preclinical modalities in anticancer drug screening. The various preclinical screening methods available such as in vitro human cancer cell lines, in vivo tumor xenograft model, or genetically engineered mouse model have their respective pros and cons. Scrupulous use of these preclinical screening methods vis-ΰ-vis efficacy of potential anticancer compound with diverse mechanism of action can help in bringing down the rate of failure of anticancer compound at clinical phase. This article provides an insight into the various preclinical methods used in anticancer studies along with their advantages and disadvantages.

Abinash Panda, Supriya Pradhan, Gurukrushna Mohapatra, Jigyansa Mohapatra
September-October 2016, 48(5):515-521
DOI:10.4103/0253-7613.190728  PMID:27721536
Objectives: The objective of this study is to identify and compare the nature of the drug-related problems (DRPs) associated with self-medication and non-self-medication (drug use guided by a prescription). Materials and Methods: The cross-sectional, observational study was conducted on 1100 adult participants at a convenience sample of six retail private pharmacy counters. The data collection form was based on the Pharmaceutical Care Network Europe version 6.2 classification for DRPs. Descriptive statistics was used to represent the prevalence of DRPs. Chi-square test was used to find out the association between the type of medication and DRPs. Odds ratio (OR) with confidence interval (CI) was computed to find the factors determining the occurrence of DRPs. P < 0.05 was considered to be statistically significant. Data were analyzed using SPSS version 16.0. Results: The prevalence of self-medication was 18.72%. The prevalence of DRPs was 17.36%. In the self-medication group, the prevalence of DRPs was high (40.78%) as compared to the non-self-medication group (11.97%). DRP related to inappropriate drug dosing was observed in 44.83% and 40.45% subjects in self-medication and non-self-medication group, respectively (P < 0.001). The subjects in the self-medication group were about 5 times likely to have a DRP (OR: 5.06, CI: 3.59-7.14, P < 0.001). Conclusions: Self-medication is associated with a higher risk of various DRPs. Since retail pharmacy outlet is often the first point of contact between the patient and the health care system in a developing country, interventions like drug information activities at the retail pharmacy is likely to bring down the DRPs associated with self-medication.

DOI:10.4103/0253-7613.190721  PMID:27721534
Objectives: Statins by their anti-inflammatory and endothelial stabilizing effect can be beneficial in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH). The present study was done to evaluate the effect of rosuvastatin on pulmonary functions and quality of life (QOL) in patients with concomitant COPD and PH. Materials and Methods: It was a prospective, randomized, double-blind, placebo-controlled, study conducted in patients with COPD and PH. A total of sixty patients were assigned to receive either rosuvastatin 10 mg or placebo once a day in addition to their conventional treatment for 12 weeks. Routine blood investigations, pulmonary functions, echocardiogram, exercise capacity, and QOL using a questionnaire were assessed at the baseline and after 12 weeks. Results: In patients of rosuvastatin group, there was a statistically significant increase in peak expiratory flow rate (PEFR) (P = 0.04) but no significant change in other pulmonary functions: Forced vital capacity (FVC), forced expiratory volume at 1 s (FVC, FEV 1 , FEV 1 /FVC), and echocardiogram parameters. There was a significant increase in 6-min walk test (6-min walk distance) (P = 0.03) at the end of 12 weeks. On comparing with placebo, rosuvastatin showed a significant reduction (P = 0.045) in COPD exacerbations while adverse effects did not differ. Conclusion: Statins have a favorable effect on patients with COPD and PH regarding the improvement in PEFR, COPD exacerbations, and exercise capacity. Such effects can be beneficial in these patients and more so in patients with concomitant coronary artery disease or hyperlipidemia where long-term benefits of statins have been established.

DOI:10.4103/0253-7613.190746  PMID:27721542
Objective: The objective of this study was to develop and validate a simple method for estimation of tramadol hydrochloride (TH) in pure and pharmaceutical dosage forms using a colorimeter. Materials and Methods: TH on reaction with Eriochrome Black T in the presence of acetate buffer at pH 3.5 forms a colored complex. This complex was extracted with a fixed volume of chloroform. The optical density of this colored complex was measured against reagent blank using a colorimeter at 520 nm. Results: Beer's law was obeyed with a good correlation coefficient (0.999) in the concentration range of 2.5 μg/ml to 10 μg/ml. Drug content estimation and recovery studies carried out on commercial tablet dosage forms demonstrated the accuracy of the method and that excipients do not cause interference. Precision and robustness were measured and found to be acceptable (% relative standard deviation <2%). Conclusion: The proposed method can be used for the rapid determination of TH content in tablets at a health-care provider level using already available staff and equipment.

Background: Most of the academic teachers use four or five options per item of multiple choice question (MCQ) test as formative and summative assessment. Optimal number of options in MCQ item is a matter of considerable debate among academic teachers of various educational fields. There is a scarcity of the published literature regarding the optimum number of option in each item of MCQ in the field of medical education. Objectives: To compare three options, four options, and five options MCQs test for the quality parameters - reliability, validity, item analysis, distracter analysis, and time analysis. Materials and Methods: Participants were 3 rd semester M.B.B.S. students. Students were divided randomly into three groups. Each group was given one set of MCQ test out of three options, four options, and five option randomly. Following the marking of the multiple choice tests, the participants' option selections were analyzed and comparisons were conducted of the mean marks, mean time, validity, reliability and facility value, discrimination index, point biserial value, distracter analysis of three different option formats. Results: Students score more (P = 0.000) and took less time (P = 0.009) for the completion of three options as compared to four options and five options groups. Facility value was more (P = 0.004) in three options group as compared to four and five options groups. There was no significant difference between three groups for the validity, reliability, and item discrimination. Nonfunctioning distracters were more in the four and five options group as compared to three option group. Conclusion: Assessment based on three option MCQs is can be preferred over four option and five option MCQs.

Advances in oncologic therapies have allowed many patients with breast cancer to achieve better outcomes and longer survival. However, this progress has been tempered by cardiotoxicity, associated with anticancer therapies, ranging from subclinical abnormalities to irreversible life-threatening complications, such as congestive heart failure or cardiomyopathy. In particular, exposure to chemotherapy (CHT), including anthracyclines and trastuzumab, can lead to cardiac dysfunction with short- or long-term consequences, among patients with breast cancer. The aim of this study is to highlight the potential role of commonly used cardiac medications in the prevention of anthracycline- and trastuzumab-mediated cardiotoxicity, in women with breast cancer, based on evidence from recent clinical trials. This overview is focused on the use of antihypertensive medications, such as angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, outlining their cardioprotective effects in this patient population. In addition, the importance of biomarkers and modern imaging tests, as potential tools for detection and monitoring of cardiac dysfunction, induced by CHT, as well as some practical preventive and therapeutic strategies for cardio-oncology treatment teams, involved in the management of a growing number of women with breast cancer have been outlined. The content of this overview is based on a literature search of PubMed, within the last 5 years, mostly in relevance to the human epidermal growth factor receptor 2-positive patients with breast cancer, treated with anthracycline or trastuzumab therapy (in addition to surgery and/or radiation therapy [RT] regimen).

DOI:10.4103/0253-7613.190740  PMID:27721539
Objectives: The aim of this study was to investigate the antipsoriatic activity of ethanolic extract of Woodfordia fruticosa flowers (EEWF) using a novel in vivo screening model. Materials and Methods: For induction of psoriasis, 0.1 ml of prepared complete Freund's adjuvant (CFA) and formaldehyde mixture (1:10 ratio) was topically applied for 7 days on the dorsum surface of the skin of Swiss albino mice. Psoriasis severity index (PSI) was evaluated by phenotypic (redness, erythema, and scales) and histological features (epidermal thickness). Therapeutic effect of 0.05% and 0.1% (w/w) ointments of EEWF was evaluated after the induction of psoriasis. Ointments of EEWF flowers were applied once daily for 3 weeks, and antipsoriatic activity was evaluated by scoring the PSI and histological examination. Results: We observed the phenotypic and histological features and found a progressive reduction (P < 0.05) in the severity of psoriatic lesions (redness, erythema, and scales) from day 7 to 21 st day and decreased epidermal thickness in animals treated with 0.05% and 0.1% (w/w) ointments of EEWF. Conclusions: The results showed that 0.05% and 0.1% (w/w) ointments of EEWF have dose-dependent beneficial effects in CFA and formaldehyde-induced psoriasis. The present investigation revealed that W. fruticosa flowers possess potent antipsoriatic activity and can be used for psoriasis treatment.

DOI:10.4103/0253-7613.190752  PMID:27721543
Objective: The current study was designed to explore anxiolytic, antidepressant, and antistress actions of Cinnamomum tamala (CT) leaves (aqueous extract) in rats. Materials and Methods: Behavioral procedures of anxiety, depression, and stress were assessed in rats. CT (100, 200, and 400 mg/kg) was given once a daily for 7 days via oral route and the efficacy was matched by those elicited by lorazepam (1 mg/kg, p.o.), imipramine (10 mg/kg, p.o.), and Withania somnifera (100 mg/kg, p.o.) for anxiolytic, antidepressant, and antistress studies, respectively. Standard drugs were given 1 time, 30 min preceding the behavioral trials. Results: One-way analysis of variance followed by Newman-Keuls multiple comparison test was employed to analyze the results. P < 0.05 was considered statistically significant as compared to control. CT at 400 mg/kg produced an antianxiety effect equivalent to lorazepam, in the elevated plus maze, open field, and social interaction tests among selected doses of the CT. CT at 400 mg/kg also induced an antidepressant activity similar to imipramine, in the behavioral despair, learned helplessness test, and tail suspension among selected doses of the CT. Moreover, CT at 400 mg/kg produced a significant antistress effect comparable to W. somnifera in water immersion-restraint stress by decreasing ulcer index, adrenal gland weight, and by normalizing the plasma levels of corticosterone, glucose, cholesterol, and triglyceride levels when related to stress control. Conclusion: The study shows that among the different CT doses, CT at 400 mg/kg possesses significant anxiolytic, antidepressant, and anti-stress effects and has therapeutic beneficial for the management of psychological ailments.

DOI:10.4103/0253-7613.190742  PMID:27721540
Objectives: The defective apoptosis is believed to play a major role in the survival and proliferation of neoplastic cells. Hence, the induction of apoptosis in cancer cells is one of the targets for cancer treatment. Researchers are considering scorpion venom as a potent natural source for cancer treatment because it contains many bioactive compounds. The main objective of the current study is to evaluate the anticancer property of Androctonus bicolor scorpion venom on cancer cells. Materials and Methods: Scorpions were milked by electrical stimulation of telsons and lyophilized. The breast (MDA-MB-231) and colorectal (HCT-8) cancer cells were maintained in appropriate condition. The venom cytotoxicity was assessed by 3-(4,5-di-methylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay, and the cellular and nuclear changes were studied with propidium iodide and 4',6-diamidino-2-phenylindole stain, respectively. The cell cycle arrest was examined using muse cell analyzer. Results: The A. bicolor venom exerted cytotoxic effects on MDA-MB-231 and HCT-8 cells in a dose- and duration-dependent manner and induced apoptotic cell death. The treatment with this venom arrests the cancer cells in G0/G1 phase of cell cycle. Conclusions: The venom selectively induces the rate of apoptosis in MDA-MB-231 and HCT-8 cells as reflected by morphological and cell cycle studies. To the best of our knowledge, this is the first scientific evidence demonstrating the induction of apoptosis and cell cycle arrest by A. bicolor scorpion venom.

Prashant P Kadam, Nithya Jaideep Gogtay, Sunil Karande, V Shah, Urmila M Thatte
September-October 2016, 48(5):498-502
DOI:10.4103/0253-7613.190720  PMID:27721533
Objectives: Studies on antimalarial kinetics in children or adults who are undernourished or malnourished are both limited and have yielded conflicting results. The present study was carried out with the objectives of evaluating the pharmacokinetics of single dose chloroquine and its metabolite desethylchloroquine in children who were undernourished and compare them with children who were normally nourished. Methods: Children of either gender between the ages of 5 and 12 years, smear positive for P. vivax malaria and classified either as well nourished or undernourished were included. Undernourishment was adjudged based on the Indian Academy of Pediatrics (IAP) classification of protein energy malnutrition [PEM] which in turn was based on Khadilkar's growth charts. All participants received 10 mg/kg on the first day followed by 10 mg/kg on Day 2 and 5 mg/kg on Day 3 along with supportive treatment. Blood samples for the levels of chloroquine [CQ] and desethylchloroquine [DECQ] were collected at 0, 0.5, 1, 2 4, 8, 12, 24, 48, 72 hours and 14 days after the first dose and levels assessed by High Performance Liquid Chromatography. Results: A total of 12 children who were normally nourished and 13 who were undernourished were studied. Wide inter-individual variability was seen in the levels of both drug and metabolite in both groups of patients. However, the differences in Cmax, AUC 0-inf, Clearance, half life and Vd between the two groups were not significantly different. Discussion: Our results indicate that dosage requirement is unlikely to be needed for chloroquine in undernourished children with uncomplicated P. vivax malaria.

Lily Dubey, Suparna Chatterjee, Alakendu Ghosh
September-October 2016, 48(5):591-594
DOI:10.4103/0253-7613.190761  PMID:27721549
Objectives: Methotrexate (MTX) is the most commonly used cost-effective disease-modifying antirheumatoid drug (DMARD). Its main dose-limiting adverse effects are hepatic and hematopoietic. This cross-sectional, observational study evaluated the prevalence of hepatic and hematological adverse effects with long-term low-dose MTX therapy. Materials and Methods: Rheumatoid arthritis (RA) patients taking ≤15 mg/week MTX for at least 2 years were enrolled from the rheumatology outpatient department. Demographic, disease, drug treatment profiles, and hematological and hepatic enzyme levels were noted. Results: Of the 204 patients enrolled, the frequency of raised alanine transaminase level (≥3-fold rise above the upper limit of normal) was 6.37% (95% confidence interval of 3.76-10.59) including two biopsy-proven hepatic fibrosis cases. About 5.4% had severe anemia (<8 g/dl) and 4.4% had leukopenia. Conclusion: Long-term low-dose MTX is safe in RA patients in the Indian population. The patterns of adverse effects were similar to those documented in earlier studies. However, our study results suggest that disease duration, cumulative MTX dose, concomitant DMARD intake are not risk factors associated with hepatic or hematological adverse effects.

September-October 2016, 48(5):576-581
DOI:10.4103/0253-7613.190758  PMID:27721546
Objective: Tinospora cordifolia is used for treatment of several diseases in Indian system of medicine. In the present study, the inhibition potential of T. cordifolia extracts and its constituent tinosporaside to cause herb-drug interactions through rat and human liver cytochrome enzymes was evaluated. Materials and Methods: Bioactive compound was quantified through reverse phase high-performance liquid chromatography, to standardize the plant extracts and interaction potential of standardized extract. Interaction potential of the test sample was evaluated through cytochrome P450-carbon monoxide complex (CYP450-CO) assay with pooled rat liver microsome. Influence on individual recombinant human liver microsomes such as CYP3A4, CYP2D6, CYP2C9, and CYP1A2 isozymes was analyzed through fluorescence microplate assay, and respective IC 50 values were determined. Results: The content of tinosporaside was found to be 1.64% (w/w) in T. cordifolia extract. Concentration-dependent inhibition was observed through T. cordifolia extract. Observed IC 50 (μg/ml) value was 136.45 (CYP3A4), 144.37 (CYP2D6), 127.55 (CYP2C9), and 141.82 (CYP1A2). Tinosporaside and extract showed higher IC 50 (μg/ml) value than the known inhibitors. T. cordifolia extract showed significantly less interaction potential and indicates that the selected plant has not significant herb-drug interactions relating to the inhibition of major CYP450 isozymes. Conclusions: Plant extract showed significantly higher IC 50 value than respective positive inhibitors against CYP3A4, 2D6, 2C9, and 1A2 isozymes. Consumption of T. cordifolia may not cause any adverse effects when consumed along with other xenobiotics.

Yuvaraj Neelakandan, Arul Venkatesan
September-October 2016, 48(5):562-570
DOI:10.4103/0253-7613.190754  PMID:27721544
Aim: The aim of this objective is to evaluate the antinociceptive and anti-inflammatory potential of sulfated polysaccharide purified fractions isolated from brown seaweed Sargassum wightii and seagrass Halophila ovalis in male Wistar rats. Subjects and Methods: Crude sulfated polysaccharide from S. wightii and H. ovalis was subjected to anion exchange chromatography, and the chemical composition was investigated. The antinociceptive activity of purified fractions was investigated using formalin and hot plate test. Carrageenan-induced paw edema, peritonitis model, and Freund's Complete Adjuvant-induced arthritis model were employed to determine the anti-inflammatory activity. Results: In the formalin test, there was a significant reduction in licking time in both phases of the test at a dose of 10 mg/kg. In the hot plate test, the antinociceptive effect was observed only in animals treated with 5, 10 mg/kg suggesting that the analgesic effect occurs through a central action mechanism. Sw FrIV and Ho FrIV significantly inhibited paw edema induced by carrageenan, especially at 3 h after treatment and potentially decreased neutrophil migration at 10 mg/kg, respectively. In Freund's adjuvant-induced arthritic rats, a significant reduction in paw volume was observed in Sw FrIV and Ho FrIV-treated groups (10 mg/kg). Conclusion: Purified components from S. wightii and H. ovalis have strong antinociceptive and anti-inflammatory effect on animal model. However, to determine the molecular mechanism, it is necessary to investigate the effect of purified fractions on inhibition of nitric oxide synthase expression mediated by inhibiting the phosphorylation of various signal proteins in lipopolysaccharide-stimulated RAW264.7 cells.

Drug Abuse has become a major challenging problem for the society. It effects people of all countries economical strata's and all ages. According. Monetary loss all over the world regarding drug abuse is in million dollars, it not only has an impact on human productivity and healthcare cost but also on cost of crimes conducted by these drugs and alcohol abuse. Therapeutic vaccine has come as new approach to deal with this problem, after failures in search for a pharmaceutical agent to deal with drug of abuse and alcohol. Research in field of nicotine abuse has gone a way ahead with number of vaccines being tried clinically followed by cocaine, opioids, methamphetamine, phencyclidine and alcohol. All of them have a common mechanism of action by antibody production whereas alcohol acts by genetic intervention. None have being approved yet due to poor results in phase II trials, possibly due to not able to trigger an adequate immunological response. But still quest is on for cracking the ice by developing first successful vaccine against drug of abuse,that would follow for other drugs too. It would be great step in field of therapeutic vaccines for drug abuse after similar successful vaccines being approved for other diseases like cancer.

Objectives: The aim of the study was to analyze the adverse drug reaction (ADR) profile of microtubule-damaging antineoplastic drugs (taxanes and vinca alkaloids) and to look for unexpected ADRs among the local population. Focused study on these drugs, rampantly used in oncology department for a wide variety of tumors including early and advanced malignancies, would enable better treatment care by physicians. Materials and Methods: Data on ADRs were collected from the cancer patients belonging to both gender and of all ages, on taxanes- or vinca-based cancer chemotherapy and reported in the Indian Pharmacopoeia Commission form. Causality was assessed using the WHO criteria and Naranjo's Algorithm. Preventability and severity of ADRs were also assessed. Results: A total of 97 ADRs were reported among 488 patients on microtubule-damaging anticancer drugs admitted over a period of 1 year. The incidence rate was 19.87%. Gastrointestinal system (40.2%) was the most affected followed by bone marrow (33%) and skin (8.2%). The highest incidence of ADRs was reported among paclitaxel (54.6%), and vincristine (39.2%). Most of the reported ADRs were of milder nature and preventable. The WHO causality assessment scale indicated 71.1% possible reactions. Conclusions: This study showed that most ADRs are preventable with effective ADR monitoring. There is a great need to create awareness among healthcare professionals regarding the importance of the pharmacovigilance system. Judicious use of the preventive measures will lead to a reduction in the incidence of ADRs due to the drug armamentarium, thereby enabling additional economic benefit to the patient and society.

DOI:10.4103/0253-7613.190737  PMID:27721538
Objectives: The present study was carried out to investigate the in vivo antimycobacterial activity of methanol extract of Alstonia scholaris and Mucuna imbricata in murine model. Materials and Methods: Female BALB/c mice were infected with the Mycobacterium tuberculosis H 37 Rv suspension. Extracts were administered orally for 2 weeks from 7 th day postinfection at a dose of 200 mg/kg and rifampicin at 20 mg/kg as standard. The synergistic groups were 10 and 100 mg/kg for rifampicin and extract, respectively. Results: The final body weight of mycobacteria-infected group was significantly reduced (15.41 ± 0.42, P < 0.01), but following treatment with the plant extract plus rifampicin could elevate the body weight. Colony forming unit (CFU) count of lung (8.71 ± 0.01) and spleen (8.59 ± 0.01) was significantly higher in infected and untreated group (P < 0.01). It was observed that activity of the synergistic group displayed powerful and maximum response against tuberculosis (TB) infection with lower CFU counts. Histopathology study showed cells such as lymphocytes, epithelioid, Langhans giant cell, and fibrous tissue proliferation in lungs; depletion of lymphocytes in the spleen. Conclusions: The data indicate that methanol extract of A. scholaris has potential antimycobacterial activity, and the synergistic group consisting of rifampicin and A. scholaris could be a rational choice for the treatment of TB.

DOI:10.4103/0253-7613.190765  PMID:27721553
Here, we report a case of a 30-year-old male who was prescribed eperisone hydrochloride for body pain and loose stools after which he developed severe maculopapular rash. Eperisone hydrochloride is  an analgesic and antispastic drug used for spastic diseases such as spastic paralysis in cerebrovascular diseases, cervical spondylosis, and periarthritis. The drug is marketed in most of the Asian countries including India, but it is not licensed. Studies show the history of hypersensitivity in other countries, but this is the first reported case in India.

September-October 2016, 48(5):595-598
DOI:10.4103/0253-7613.190762  PMID:27721550
Objectives: The objective of this study was to evaluate any abnormal change in plasma glucose levels in patients treated with L-asparaginase (L-Asp)-based chemotherapy regimen in patients of acute lymphoblastic leukemia (ALL). Materials and Methods: This retrospective, hospital-based study was conducted in patients of ALL, admitted to the Clinical Haematology Department of a tertiary care hospital of Odisha from August 2014 to July 2015. Indoor records of 146 patients on multi-centered protocol-841 were evaluated for any alteration in plasma glucose level, time of onset of hypo/hyperglycemia, and persistence of plasma glucose alteration. Results: Twenty-one percent of patients showed abnormal plasma glucose level. Most of these patients developed hypoglycemia and were of lower age group. Most of these patients developed hypoglycemia and were of lower age group, whereas a majority of higher age group patients developed hyperglycemia. In majority of the cases, abnormal glucose developed after three doses of L-Asp. Hypoglycemia subsided whereas hyperglycemia persisted till the end of our observation period. Conclusions: L-Asp produces more incidences of hypoglycemia than hyperglycemia in a good number of ALL patients towards which clinicians should be more vigilant. However, hyperglycemia persists for a longer duration than hypoglycemia.

Nathani Minaz, Rema Razdan
September-October 2016, 48(5):544-549
DOI:10.4103/0253-7613.190744  PMID:27721541
Background: Diabetes-induced oxidative stress and hypertension play a major role in the development of nephropathy. Hence, the present study was undertaken to evaluate the protective effects of molsidomine, a nitric oxide donor in streptozotocin (STZ)-induced diabetic nephropathy (DN) in rats. Materials and Methods: Type 1 diabetes was induced through a single dose of STZ (52 mg/kg, i.p.) in male Wistar rats and then treated with molsidomine (5 and 10 mg/kg; p.o.) for 8 weeks. Physical parameters, vital and renal function test including blood glucose, albuminuria, blood urine nitrogen, serum creatinine, and kidney index were determined. Oxidative stress and lipid peroxidation were assessed in the kidney homogenate by means of antioxidant enzymes and malondialdehyde levels. Results: DN rats exhibited a significant renal dysfunction with a reduction in body weight, excessive oxidative stress, and pathological changes. Molsidomine treatment significantly improved vital sign, renal functions, and oxidative stress in DN rats in a dose-dependent manner. The protective effect of molsidomine was also substantiated by pathological changes in the architect of the kidney. Conclusion: Molsidomine shows a significant beneficial effect in Type 1 DN in rats.

Background: Ritonavir-boosted atazanavir (ATV/r) is the preferred second-line protease inhibitor (PI) option for HIV patients in resource-limited settings; its pattern of adverse drug reactions (ADRs) has not been much reported from India; hence, in this study, we have analyzed the incidence of ATV/r-associated ADRs in Southern Indian HIV-1-infected patients. Methods: In this prospective study, 111 HIV patients treated with ATV/r were included with at least 2 years follow-up visits for the emergence of hyperbilirubinemia, hypertransaminasemia, and serum creatinine elevation. The causality assessment was done based on the WHO scale for the causality assessment of suspected ADR. Results: The incidence of severe hyperbilirubinemia, hypertransaminasemia, and creatinine elevation was 28.6, 0.76, and 1.62 cases/100 person years, respectively. 3TC/FTC + TDF (odds ratio [OR]: 6.07, confidence interval [CI]: 1.31-27.98, P = 0.015) nucleos (t) ide reverse transcriptase inhibitor backbone and male sex (OR: 18.64, CI: 2.13-162.93, P = 0.0082) were found to be significantly associated with hypertransaminasemia and creatinine elevation, respectively. The causality assessment of ADR was "possible" for all the participants. Kaplan-Meier analysis showed hyperbilirubinemia to emerge earlier (mean duration: 32.18 months, CI: 24.9-39.4 months) followed by hypertransaminasemia and creatinine elevation. Hyperbilirubinemia is an expected side effect associated with ATV/r which is benign, transient, and does not predispose to hypertransaminasemia. Conclusion: Our study results show that patients starting ATV/r should be counseled for a good adherence in spite of the emergence of hyperbilirubinemia which generally reverts to normal range.
