Prevalence and pattern of self-medication in elderly individuals

Background: Self-medication that is taking medicines without prescription by the doctor is highly prevalence in the community. Elderly population is more likely to self-medicate due to multiple morbidities. This study was undertaken to evaluate the prevalence and pattern of use of self-medication among elderly individuals.Methods: Study was carried out at tertiary care hospital. The questionnaire which was used in our earlier studies regarding self-medication was utilized. After obtaining consent, the elderly individuals (≥60 years) reporting for health check-up were requested to fill up the questionnaire themselves or were asked to respond to questions verbally in the case of illiterate. Questionnaire mainly contained demographic and clinical data and self-medication details - frequency, symptoms/disease for self-medication, drugs, reasons for self-medication, sources of information, awareness regarding the risk of self-medication.Results: Out of 200 elderly included in the study, 177(88.5%) reported self-medication in 6-month recall period. About 60% were male and mean age - 69.64±6.21 (60-85) years. About 21% reported frequent self-medication. Abdominal pain (16%) and headache (14%) were the most common symptoms, and diabetes (7%) was the most common disease for self-medication. Allopathic medicines (55%) mainly paracetamol (13.5%) were most frequently used followed by home remedies (23%) and ayurvedic (17%). Previous experience with the drug (50%) followed by advertisements (23.2%) were common source of information. Most common reasons for self-medication were convenience (69.5%) and cost (56%). None of respondents were aware of risks of self-medicationConclusion: Self-medication is highly prevalent in elderly people who are unaware of risks involved

Comparison of analgesic, anti-inflammatory and anti-pyretic efficacy of diclofenac, paracetamol and their combination in experimental animals

Background: Various combinations of analgesics antipyretic drugs are available in the market for treatment of various musculoskeletal disorders and pain relief. Diclofenac and paracetamol combination is most commonly used combination and its rationality is questionable. The objective of this study was to compare the analgesic, anti-inflammatory and anti-pyretic activities of diclofenac, paracetamol and their combination.Methods: Experimental animals were divided into 4 different groups – control, diclofenac, paracetamol and their combination. Analgesic activity was compared by using tail-clip method in rats and writhing test in mice, anti-inflammatory activity was compared by carrageenan paw edema method using plethysmometer and anti-pyretic action was compared using TAB vaccine induced pyrexia and measuring the rectal temperature. Different doses of diclofenac (1mg/kg and 2mg/kg) and paracetamol (10mg/kg and 20mg/kg) used and same doses were used in combination group.Results: Diclofenac sodium (1mg/kg) showed significantly higher analgesic activity using tail-clip and writhing method compared to paracetamol (10mg/kg) (p<0.0001) and the combination group (p<0.05). Diclofenac sodium (2mg/kg) showed significantly higher analgesic activity using tail-clip and writhing method compared to paracetamol (20mg/kg) (p<0.0001) and the combination group (p<0.1). Diclofenac has no significant difference in anti-inflammatory activity using carrageenan induced paw edema when compared to the combination group (p<0.1) for both doses. But diclofenac when compared to paracetamol for anti-inflammatory effect, it was highly significant (p<0.0001 and p<0.0004) for both doses at 1st and 3rd hour. Paracetamol 20mg/kg was superior antipyretic (p<0.05,0.01 and 0.01 ) when compared to the combination group at 1hr, 2hr and 3hr duration after injecting TAB vaccine.Conclusion: Diclofenac and paracetamol combination was either equal or inferior in all three activities studied as compared to the individual drugs

The Association between Vaccination and Autoimmunity

Vaccines are one of the prime preventive measures against infectious diseases. Administration of vaccination may lead to significant autoimmune manifestations. There is a vast literature on autoimmune issues associated with vaccines including animal and in-vitro studies, case reports and case series. Contrary to this, epidemiological research work does not report this association. This review on the potential association between vaccines and the development of autoimmune diseases is based on currently available scientific literature. We conclude that vaccines have a very positive impact on human health. Further research is required to clarify the association between vaccines and autoimmune conditions and also the detailed mechanisms behind this

Background: To study the pattern of utilization of drug in the patients of Acute Coronary Syndrome at tertiary care hospital.Methods: Prospective cross-sectional observational drug utilization study was conducted in patients of acute coronary syndrome admitted in ICCU, for the period of two months. Data was collected in preformed Case record form. Analysis was done by using drug use indicators, demographic pattern, morbidity pattern of disease, pattern of drug use. Data analysed using Microsoft Excel SPSS software - version 21.l. Total 71 cases were analysed.Results: In our study we analysed 71 patients out of that 50 were male and 21 were female patients. The mean age of patient was 57.61±11.09 yr; most belonging to age group of 51-60 years (36.62%). Number of patients undergoing thrombolysis were 28(39.43%) and 43(60.57%) underwent percutaneous coronary intervention (PCI). Total 44 different drugs were used and 565 drugs were prescribed in 71 patients. Most frequently prescribed drugs were Clopidogrel and aspirin in 100% encounters, followed by atorvastatin (85%).Average number of drugs per encounter was 7.96. Percentage of drugs prescribed by generic name was 16.28%.Conclusions: The present study provides valuable insight about the overall pattern of drug used in Acute Coronary syndrome. Physician should be encouraged to prescribe drugs with generic name

Pattern of antidiabetic drugs use in type-2 diabetic patients in a medicine outpatient clinic of a tertiary care teaching hospital

Background: Diabetes mellitus (DM) is an important public health problem in developing countries. Drug utilisation study of antidiabetic agents is of paramount importance to promote rational drug use in diabetics and make available valuable information for the healthcare team. The aim of study was to investigate the drug utilization pattern in type-2 diabetic patients.Methods: A prospective, cross-sectional study was carried out in medicine outpatient clinic of tertiary care hospital, Ahmedabad for eight weeks. Patients with type-2 diabetes and on drug therapy for at least one month were included. Patients’ socio-demographic and clinical data were noted in a pre-designed proforma. Data was analysed by using SPSS version 20 and Excel 2007.Results: Total 114 patients were enrolled with mean (± standard deviation) age and duration of diabetes of 56.8 ± 10.5 and 8.3 ± 9.4 years respectively. Male: Female ratio was 0.72:1. Mean fasting and postprandial blood glucose levels were 147.5 ± 73.1 and 215.6 ± 97.3 mg/dl respectively. Most common symptom was weakness/fatigue (77.2%). Hypertension (70.2%) was most common co-morbid illness. Mean number of drugs prescribed were 7.8 ± 2.5. Total numbers of patients receiving more than five drugs were 89.5%. Most commonly used drug group was biguanides (87.7%) followed by sulphonylureas (68.4%).Conclusion: Metformin (biguanide) was the most utilized (87.7%) antidiabetic drug for type-2 diabetes. This study revealed that the pattern of antidiabetic prescription was rational and largely compliant with NICE (National Institute for Health and Clinical Excellence) guidelines

Voltage Gated Calcium Channels Negatively Regulate Protective Immunity to Mycobacterium tuberculosis

Mycobacterium tuberculosis modulates levels and activity of key intracellular second messengers to evade protective immune responses. Calcium release from voltage gated calcium channels (VGCC) regulates immune responses to pathogens. In this study, we investigated the roles of VGCC in regulating protective immunity to mycobacteria in vitro and in vivo. Inhibiting L-type or R-type VGCC in dendritic cells (DCs) either using antibodies or by siRNA increased calcium influx in an inositol 1,4,5-phosphate and calcium release calcium activated channel dependent mechanism that resulted in increased expression of genes favoring pro-inflammatory responses. Further, VGCC-blocked DCs activated T cells that in turn mediated killing of M. tuberculosis inside macrophages. Likewise, inhibiting VGCC in infected macrophages and PBMCs induced calcium influx, upregulated the expression of pro-inflammatory genes and resulted in enhanced killing of intracellular M. tuberculosis. Importantly, compared to healthy controls, PBMCs of tuberculosis patients expressed higher levels of both VGCC, which were significantly reduced following chemotherapy. Finally, blocking VGCC in vivo in M. tuberculosis infected mice using specific antibodies increased intracellular calcium and significantly reduced bacterial loads. These results indicate that L-type and R-type VGCC play a negative role in M. tuberculosis infection by regulating calcium mobilization in cells that determine protective immunity

Inappropriate surgical chemoprophylaxis and surgical site infection rate at a tertiary care teaching hospital

OBJECTIVES: This study aimed to analyze the pattern of surgical chemoprophylaxis, surgical site infection rate, and to check rationality of surgical chemoprophylaxis based on Kunin's criteria. MATERIALS AND METHODS: A prospective, observational study was performed on patients undergoing surgery, in a tertiary care teaching hospital. Data were collected in a pro-forma which included the patients' details, prescriptions from date of admission to discharge or any other outcome and operative notes. Surgical site infection as defined by Centre for Disease Control criteria was recorded. Rationality was assessed based on Kunin's criteria. RESULTS: Total 220 patients were enrolled over a period of one year. Mean hospital stay was 8.67 ± 5.17 days. A total of 2294 drugs were prescribed out of which 840 (36.61%) were antimicrobials. Mean duration for pre-operative intravenous antimicrobial therapy was 0.75 ± 0.45 day and for post-operative intravenous antimicrobial therapy was 3.33 ± 2.24 days while post-operative oral antimicrobial therapy was 4.58 ± 3.34 days. Third generation cephalosporins were prescribed most frequently 64.74% and 64.40% pre-operatively and post-operatively respectively. Antimicrobial prescribing was inappropriate in 52.28%. Total of 19 patients developed surgical site infection. Surgical site infection rate was significantly higher (13.04%) in patients receiving inappropriate chemoprophylaxis (p < 0.01). Surgical site infection adds 9.98 days of hospital stay (p < 0.0001) and 3.57 extra drugs (p < 0.0001) compared to group without surgical site infection. CONCLUSION: Inappropriate use of antimicrobials is highly prevalent in surgical chemoprophylaxis leading to higher surgical site infection rate. Adoption of international standard and formulation of locally feasible guidelines can help overcome this situation
