ABSTRACT
Background: India is an agrarian country, where pesticides are most widely used in farming. Monsoon dependent agricultural practices are common in India. In present study socioeconomic class and prescribing pattern of commonly used drugs in organophosphate poisoning in indoor setting at tertiary care hospital is evaluated. The aim of the study was to evaluate prescribing trend of drugs and socioeconomic class of patients in organophosphate poisoning in monsoon season.Methods: Prospective observational study was conducted at Medical Intensive Care Unit (MICU) and Medicine Wards for 4 months at 540 bedded tertiary care teaching hospital.Results: Total 64 diagnosed cases were enrolled and analyzed in present study (n=64). Maximum number of cases (57.81%) were male followed by female (42.18%). Most of the cases (37.50%) were from the age group of 21-30 years. 49 (76.56%) patients were of primary intentional poisoning followed by 15 (23.43%) patients of accidental poisoning. Most common drugs prescribed were atropine, pralidoxime, cefotaxime and ranitidine. The average amount of atropine and pralidoxime used per patient/day were 37.89±63.63 mg and 10.07±26.87 gm respectively.Conclusions: Present study revealed that young male adults with low socioeconomic class from rural background were prone for intentional organophosphate poisoning in central India.
ABSTRACT
Background: Depression, a common mental disorder characterized by persistent unhappiness and lack of interest in daily activities, is one of the major important public health problems that are often comorbid with other chronic diseases like diabetes and can worsen the effect of the disease outcomes. Depression alone and/or as a comorbidity with diabetes is a common condition in the community. Aim of the study: To identify the prevalence of Depression among Type 2 Diabetes Mellitus patients and relationship between Depression and its effect on Drug Compliance among Type 2 Diabetes Mellitus patients, to determine the severity of Depression among Type 2 Diabetes Mellitus patients and the extent to which it affects Drug compliance. Materials and methods: The study was to be conducted in Rajah Muthiah Medical College and Hospital, Chidambaram in the year 2018-2019. A hundred patients with diagnosis of T2DM attending Diabetic OPD above 20 years of age were randomly selected. The Hamilton rating scale for depression by Hamilton is the most widely used rating scale to assess the symptoms of depression. The Ham-D is an observer-rated scale consisting of 17-21 items. Ratings are based on clinical interview. The items are rated on either a 0 to 4 spectrum or a 0 to 2 spectrum. The HAM-D also relies quite heavily on the clinical interviewing skills and the experience of rater in evaluating individuals with depressive illness. The strength of HAM-D is its excellent validation/research base, K.H. Mohamed Ibrahim, R. Gandhi Babu, M. Senthil Velan.

Its use is limited in individuals who have psychiatric disorders other than primary depression. Results: Analyzing with HAMD score, 40 had no depression, mild depression in 24 cases, moderate depression in 21 cases, severe depression in 15 cases. MAQ score scale- low adherence in 41 cases, medium adherence in 37 cases, high adherence in 22 cases. MMAQ score scale and HAMD scorelow adherence with no depression were 9 cases (22.5%) mild depression were 6 cases (25%) moderate were 11(52.4%) severe depression were 15 cases (100%). MMAQ score scale and HAMD score - medium adherence with no depression were 23 cases (57.5%) mild depression were 9 cases (37.5%) moderate were 5(23.8%) severe depression were not seen. MMAQ score scale and HAMD score - Medium adherence with no depression were 8 cases (20%) Mild depression were 9 cases (37.5%) Moderate were 5(23.8%) severe depression was not seen. Pearson Chi-Square = 35.344**, p<0.001. Conclusion: Further, there was a significant association between the depression in Type 2 diabetes patients and medication adherence, where patients with depression had poor medication adherence as compared to those without depression and severity of depression correlates with worse adherence to diabetic medications
ABSTRACT
Background: In developing countries, the widespread use of organophosphorus compounds (OPCs) has been accompanied by increasing incidence of poisoning with these agents, both suicidal and accidental. This is attributed mainly to their easy availability, indiscriminate handling, storage and lack of knowledge about the serious consequences of poisoning. Of the various substance used for suicidal attempts in India, OPCs form a significant group. Since the clinical manifestation of OPC poisoning is diverse ranging from mild symptoms to fatal complications in the course of time, we need proper management of the situation. Materials and methods: We studied 50 patients of organophosphorus poisoning. We checked vital parameters, general examination and systemic examination. We also checked for various parameters on like cholinesterase level, complete blood counts, renal function test with electrolytes, liver function test. Results: In this study majority of patients fell in 20-30 years of age group with male predominance from lower and middle socio-economical class and most common reason was suicidal. Precipitating event were domestic problem, marital friction and financial problem. Most common clinical features were vomiting, miosis and giddiness. Majority of the patients belonged to mild grade. The average S.cholinesterase level was low as severity increases. More doses of PAM and atropine are required in severe poisoning. Most common complication was respiratory paralysis. Death was more in severe poisoning. Conclusion: OPC is one of the most common poisoning in India. Reason for poisoning is most commonly suicidal. It is common in male with low socio-economical class mainly due to domestic Janak Chokshi, Kothi Zuber Suleman, Bhavikkumar Prajapati. A study of 50 cases of Organophosphorus poisoning and its complications. IAIM, 2019; 6(1): 16-22. Page 17 problems, financial issue and unhappy married life. In patients of OP poisoning presenting symptoms and S.ChE level directly correlated with severity. Therapeutic required dose of PAM and atropine are different in different grade of severity. Survival amongst patients is definitely better if atropine and PAM are being given with Mechanical ventilator support in cases of respiratory insufficiency.
ABSTRACT
Objective To investigate the effect of different doses of pralidoxime chloride on clinical outcome including recovery rate and mortality in patients with acute organophosphorus pesticide poisoning.Methods According to the total amount of pralidoxime chloride administered over the first 24 hours or entire duration of hospitalization,a cohort of 163 organophosphorus pesticide poisoning patients,admitted from February 2004 to December 2014 were assigned to different groups followed by a retrospective analysis.Comparisons of recovery rate,mortality rate,mean length of hospital stay,and duration of mechanical ventilation were made among groups.SPSS 18.0 was used to analyze categorical variables between the data of groups with x2 test/Fisher exact probability method and numerical variables with t test or One-way ANOVA,and statistical significance was set as P ＜ 0.05.Results According to the amount of pralidoxime chloride given over the first 24 hours,the recovery rate and the mortality rate were significantly improved in the experimental group (pralidoxime chloride ＞ 2 g) than in the control group (pralidoxime chloride ＜ 2 g) (P =0.04).There was no significant difference in mean length of hospital stay between the experimental group and the control group (P =0.171),and there were statistically significant differences in recovery rate and mortality rate among the four dose-response subgroups (total dosage administered in 24 hours in group A ＜ 1 g,in group B ＜2 g,in group C ＜4 g and in group D ＞4 g) (P =0.034).Based on the total amount of pralidoxime chloride prescribed in the entire duration of hospital stay,the recovery rate and mortality rate were significantly better in the experimental group than those in control group (P =0.002),and among the three dose-response subgroups,the significant difference in recovery rate and mortality rate were also observed (P =0.006).Conclusions Increased amounts of pralidoxime chloride prescribed in the first 24 hours and in the whole hospitalized period can improve the recovery rate and reduce the mortality rate in organophosphorus pesticide poisoning patients.
ABSTRACT
Background: Drug-related problems are an important cause of morbidity and mortality and a significant burden on healthcare resources. There are few studies to account for errors in drug intake leading to adverse drug reactions (ADRs). This study was pursued with the objective of determining the frequency and severity of the ADRs resulting from erroneous drug intake, the expenses incurred in treating the same. Methods: The study was a prospective, cross-sectional, observational study. The study subjects were patients with ADRs due to errors in drug intake and from selfmedication. All the information regarding the ADR were collected as per ADR reporting form issued by Central Drugs Standard Control Organization. Causality was assessed by both Naranjo and the WHO criteria for causality assessment. Direct cost of all the medications, hospital charges (admission, bed charges, consultations paid, treatment charges, investigations, and conveyance charges) were recorded to find the financial burden due to error in drug intake. Results: The study showed that nearly 30% of the ADRs were due to errors in drug intake and the major contributing factor is self-modification either by discontinuation or missed doses. Major drugs that are implicated in these ADRs were that of metformin and insulins among anti-diabetic drugs and amlodipine and atenolol among antihypertensives. These two groups contributed to 18 (62%) of the total 29 ADRs. Organ system commonly involved was central nervous system and that was followed by musculoskeletal system. The average direct cost incurred in the management of these ADRs was Rs. 5773 for non-serious adverse events (SAE’s) and Rs. 11,400 for SAE’s. Conclusion: Proper education about the importance of compliance and damaging consequences of self-modification of drug dosage in patients who are on treatment for chronic disorders like diabetes and hypertension will be an effective strategy to prevent many of these ADRs.
ABSTRACT
Background: Comparison of the efficacy of atropine alone against atropine with pralidoxime in the treatment of organophosphorus (OP) poisoning. Methods: Forty two patients between the age group of 18 to 65 years, treated for OP poisoning and matched for baseline characteristics, were included in two groupsbased on treatment received as “Atropine only” or “Atropine plus pralidoxime(PAM)”.Main outcomes of the study were ICU stay, total hospital stay and mortality. ICU and hospital stay were compared using ‘t’ test while mortality was compared using Fisher’s exact test. Results: Total hospital stay was not significantly different between the treatment groups (95% CI of difference: -4.227, 0.784). Length of stay was also not significantly different between patients who received atropine plus PAM within 6 hours of consumption of poison and those who received 6 hours later (95% CI of difference: -4.154, 0.954; p value: 0.2). Conclusion: Our data supports the use of only atropine over atropine plus PAM in patients with OP poisoning on account of no significant difference /reduction of hospital/ICU stay and mortality in the latter group. However, a study with a larger sample needs to be conducted, to be able to draw a definitive conclusion.
ABSTRACT
Acute organophosphate (OP) poisoning produces cholinergic symptoms resulting from the inhibition of cholinesterase, and the overstimulation of muscarinic and nicotinic receptors in the synapses. The dominant clinical features of acute cholinergic toxicity include bradycardia, miosis, lacrimation, salivation, bronchorrhea, and bronchospasm. All symptomatic patients should receive therapy with oxygen, atropine, and pralidoxime. Atropine works as a physiologic antidote by competitively occupying muscarinic receptor sites, reducing the effects of excessive acetylcholine. Atropine should be immediately administered, and the dose can be titrated according to the severity of OP poisoning. A large dose may be necessary to overcome the excessive cholinergic state in case of severe poisoning. Pralidoxime is a biochemical antidote that reactivates acetylcholinesterase by removing OP from it. It is effective in treating both muscarinic and nicotinic symptoms. After some period of time, the acetylcholinesterase-OP compound undergoes a conformational change, known as aging, which renders the enzyme irreversibly resistant to reactivation by a pralidoxime. There has been a great deal of controversy over the effectiveness of pralidoxime in acute OP poisoning. However, it may be beneficial to administer pralidoxime for a sufficient period in case of severe poisoning with a large quantity of OP, which is common in Korea.

ObjectiveTo study the role of catecholamine in genesis of myocardium injury after organophosphorus poisoning (OP) in order to elucidate the underlying mechanisms of OP-induced cardiotoxicity.Methods Of 92 patients with severe acute dichlorvos poisoning,41 were consecutively enrolled for study and followed up for three months. The levels of serum creatine kinase isoenzyme myocardium (CK-MB),cardiac troponin Ⅰ (cTnI),acetylcholinesterase (AChE),acetylcholine (Ach),epinephrine and norepinephrine were assayed on the 1st,3rd and 5th days after admission and on the day of discharge.Electrocardiography was recorded every day after admission.ResultsOf them,37 (90.2％ )patients survived and four ( 9.8％ ) patients died during treatment.Sinus tachycardia was found in 37 (90.2％ ) patients and ST-T changes in 33 (80.4％ ) patients.CK-MB and cTnI levels peaked 3 days after admission,and then decreased to normal levels.Serum Ach,epinephrine and norepinephrine peaked on the 1st day after admission and then decreased.ConclusionsSevere acute dichlorvos poisoning is associated with myocardial dysfunction likely caused by increase in catecholamine levels.
ABSTRACT
Since its discovery in 1956, pralidoxime has been used in the management of organophosphorus poisoning (OP) in addition to atropine. While efficacy of atropine is proved beyond doubt, clinical experience with pralidoxime has led to widespread controversies about its efficacy in treatment of OP poisoning. In this study we compared the efficacy of add-on pralidoxime therapy over therapy with atropine alone in OP poisoning. In this open-label, parallel-group clinical study, patients of OP poisoning, presenting in emergency department of a tertiary care district hospital, were randomly allocated to receive either atropine or atropine plus pralidoxime. The parameters used for efficacy assessment were: mortality rate, requirement of ventilator and duration of stay in the hospital in either of the two treatment arms.The mortality rate, requirement of ventilator and duration of hospital stay in the two treatment arms failed to show any statistically significant difference. Add-on pralidoxime therapy over atropine monotherapy, does not offer any significant advantage in the management of OP poisoning.
ABSTRACT
PURPOSE: The optimal dose of oximes for use in the treatment of organophosphorus pesticide poisoning has not been conclusively established. In this retrospective study, we assessed the effectiveness of the use of high-dose pralidoxime infusion in treating organophosphorus pesticide poisoning. METHODS: From January 1998 to December 2009, 71 patients visited the hospital Emergency Department (ED) as a result of organophosphate pesticide intoxication. All of these patients received an initial bolus of 2 g of pralidoxime as the first step of treatment. Patients who then received continuous infusion of pralidoxime at a dose of 500 mg/hr were entered into study group 1 (low dose), and those treated by continuous infusion of pralidoxime at a dose of 1000 mg/hr were entered into study group 2 (high-dose). Plasma cholinesterase activities for each patient were evaluated at ED arrival and re-evaluated 24 hours after pralidoxime infusion. The effectiveness of the two treatment modalities was gauged by comparing the required duration of mechanical ventilation, time spent in the intensive care unit (ICU) and total time spent in the hospital. RESULTS: The mean duration of mechanical ventilation was 9.98+/-6.47 days for group 1 and 4.39+/-6.44 days for group 2. The respective mean duration of time spent in ICU and the total number of days in the hospital were 16.38+/-18.84 days and 21.87+/-20.16 days for group 1, and 7.83+/-9.99 days and 11.71+/-13.53 days for group 2. High-dose pralidoxime treatment was associated with shorter required durations for mechanical ventilation, ICU and hospital stay. In addition, plasma cholinesterase reactivation rates were higher for those patients receiving high-dose pralidoxime treatment. CONCLUSION: The results suggest that high-dose pralidoxime treatment has greater efficacy for patients suffering from organophosphorus pesticide poisoning.

ABSTRACT
PURPOSE: Pralidoxime(2-PAM) is the mainstay of organophosphate intoxication management as an antidote. We investigated the usefulness of high-dose pralidoxime therapy. METHODS: From January 2000 to July 2003, 86 patients presented with organophosphate insecticide intoxication to the emergency medical center of Chonnam National University Hospital. They were randomized into two groups: Group I was given continuous IV infusion of pralidoxime in dose of 500 mg/hr after an initial bolus dose of 2 g and Group II was given continuous IV infusion of pralidoxime in dose of 1000 mg/hr after an initial bolus dose of 2 g. Both groups were given same therapeutic interventions, including the duration of atropine administration. The plasma cholinesterase activites were monitored at admission and at 24 hr and 48 hr after infusion of pralidoxime. The effectiveness of the two treatment modalities were gauged by comparing the durations of mechanical ventilation and intensive care unit (ICU) stay. RESULTS: The mean durations of mechanical ventilation were 9.82+/-6.45 days in group I and 6.51+/-4.50 days in group II. The mean durations of ICU stay were 12.82+/- 7.69 days in group I and 9.15+/-5.38 days in group II. group I showed that longer durations of mechanical ventilation (p=0.03) and ICU stay( p<0.001). The plasma cholinesterase reactivation rate were higher in group II than in group I. CONCLUSION: The results suggest that continuous high-dose pralidoxime therapy may be helpful in the treatment of organophosphate intoxication.

Organophosphate pesticides are used extensively worldwide, and poisoning by these agents, particularly in developing nations is a public health problem. Organophosphorous nerve agents are still considered as potential threat in both military or terrorism situations. The mechanism of toxicity is the inhibition of acetylcholinesterase, resulting in accumulation of the neurotransmitter acetylcholine and continued stimulation of acetylcholine receptors both in central and peripheral nervous systems. Beside acute cholinergic crisis, organophosphates are capable of producing several subacute or chronic neurological syndromes. The well described intermediate syndrome (IMS) emerges 1-4 days after an apparently well treated cholinergic crisis. The standard treatment consists of reactivation of inhibited acetylcholinesterase with an oxime antidote (pralidoxime, obidoxime, HI-6 and Hlo7) and reversal of the biochemical effects of acetylcholine with atropine. The newer oximes HI-6 and Hlo& are much more suitable and efficacious acetylcholinesterase reactivator for severe acute nerve agent induced poisoning than currently used pralidoxime or obidoxime. Patients who receive treatment promptly usually recover from acute toxicity but may suffer from neurologic sequelae.
