RESUMO

Background & objectives: Female genital tuberculosis (FGTB) is an important variety of extrapulmonary TB causing significant morbidity, especially infertility, in developing countries like India. The aim of this study was to evaluate the laparoscopic findings of the FGTB. Methods: This was a cross-sectional study on 374 cases of diagnostic laparoscopy performed on FGTB cases with infertility. All patients underwent history taking and clinical examination and endometrial sampling/biopsy for acid-fast bacilli, microscopy, culture, PCR, GeneXpert (only last 167 cases) and histopathological evidence of epithelioid granuloma. Diagnostic laparoscopy was performed in all the cases to evaluate the findings of FGTB. Results: Mean age, parity, body mass index and duration of infertility were 27.5 yr, 0.29, 22.6 kg/m2 and 3.78 years, respectively. Primary infertility was found in 81 per cent and secondary infertility in 18.18 per cent of cases. Endometrial biopsy was positive for AFB microscopy in 4.8 per cent, culture in 6.4 per cent and epithelioid granuloma in 15.5 per cent. Positive peritoneal biopsy granuloma was seen in 5.88 per cent, PCR in 314 (83.95%) and GeneXpert in 31 (18.56%, out of last 167 cases) cases. Definite findings of FGTB were seen in 164 (43.86%) cases with beaded tubes (12.29%), tubercles (32.88%) and caseous nodules (14.96%). Probable findings of FGTB were seen in 210 (56.14%) cases with pelvic adhesions (23.52%), perihepatic adhesions (47.86%), shaggy areas (11.7%), pelvic adhesions (11.71%), encysted ascites (10.42%) and frozen pelvis in 3.7 per cent of cases. Interpretation & conclusions: The finding of this study suggests that laparoscopy is a useful modality to diagnose FGTB with a higher pickup rate of cases. Hence it should be included as a part of composite reference standard.

RESUMO

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been used for almost a decade and have proven to be effective not only in managing Type 2 diabetes (T2D), but their cardio and renal protective features make them very useful in managing patients with risk of multiple comorbidities. This systematic review was undertaken by the authors because there is no evidence currently available in India that has studied the suitability of SGLT2i as a first-line agent in patients newly diagnosed with T2D in India. MATERIALS AND METHODS: First, literature was searched to identify features that are considered important when deciding on a first-line agent for managing T2D. A total of 5 broad topics were identified-glycemic control, extra glycemic effects, antihyperglycemic combination therapy, safety, and cost-effectiveness. These domains had further subheadings, and a total of 16 domains were identified. Metformin is the drug of choice as a first-line agent in such situations and has been considered the gold standard for evaluating the effects of SGLT2i across these domains. A systematic literature review on each domain was conducted to compare SGLT2i with the gold standard in Indian patients newly diagnosed with T2D. Evidence was graded (levels of evidence (LoE)-A, B, and C), and recommendations (class of recommendation (CoR)-I, II, and III) were classified by the expert group as defined in the methodology. RESULTS: According to the systematic reviews conducted, 11 domains had Level A evidence, 2 domains (impact on lipids and gut microbiome) had Level B, and 3 domains had Level C (ß-cell function, renal protection, and glycemic variability) evidence. Based on evidence and expert opinion, the authors recommend SGLT2i as a first-line agent for managing newly diagnosed patients with T2D with a Class I recommendation for 13 domains and Class II for the remaining 3 (impact on lipids, gut microbiome, and ß-cell function). Although a poorer level of evidence (Level C) was available for the glycemic variability domain, the authors still reported this as Class I recommendations according to their expert opinion and consensus. CONCLUSION: This article advocates adopting SGLT2 inhibitors as the primary treatment choice for treating patients with newly diagnosed T2D in India.

RESUMO

Colorimetric sensors have emerged as a powerful tool in the detection of water pollutants. Plasmonic nanoparticles use localized surface plasmon resonance (LSPR)-based colorimetric sensing. LSPR-based sensing can be accomplished through different strategies such as etching, growth, aggregation, and anti-aggregation. Based on these strategies, various sensors have been developed. This review focuses on the newly developed anti-aggregation-based strategy of plasmonic nanoparticles. Sensors based on this strategy have attracted increasing interest because of their exciting properties of high sensitivity, selectivity, and applicability. This review highlights LSPR-based anti-aggregation sensors, their classification, and role of plasmonic nanoparticles in these sensors for the detection of water pollutants. The anti-aggregation based sensing of major water pollutants such as heavy metal ions, anions, and small organic molecules has been summarized herein. This review also provides some personal insights into current challenges associated with anti-aggregation strategy of LSPR-based colorimetric sensors and proposes future research directions.

RESUMO

India has a sparkling pharmaceutical sector that holds a distinguished place by producing and supplying high-quality and affordable medicines across the globe. Ensuring the quality and safety of the marketed medicinal products is one of the most important components of the drug regulatory framework and assessment of the quality of medicines is usually achieved by referring to the public standards of the official Pharmacopoeia. In India, the Indian Pharmacopoeia (IP) is published at regular intervals to fulfill the requirements of the Drugs and Cosmetics Act, 1940 to ensure the quality of medicines being manufactured and/or marketed in India. The present article aims to provide an overview of the history of the IP, its standards-setting process, and the current status of monographs in the 9th edition of the IP 2022. Special focus is placed on the newly added and upgraded general chapters and monographs within the IP 2022. There are a total of 223 general chapters and 3152 drug monographs available under various categories in the IP 2022. This study also highlights a total of 92 new drug monograph additions and 412 monograph revisions in the IP 2022. It is anticipated that the standards laid down in the IP 2022 will play an imperative role in delivering quality medicines to patients within and outside India.

RESUMO

Background & objectives: Several studies have been conducted globally to assess the impact of usage of mobile phones on quality and duration of sleep as also on day time sleepiness. The objective of the present study was to assess the effect of mobile phone usage on the quality and composition of sleep in a sample from Indian population. Methods: The study was conducted at two tertiary care hospitals in north India from July 2014 to September 2019. A total of 566 participants were recruited in this study from both the centres. Sleep quality was assessed with the help of the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Subsequently, actigraphy was done in 96 participants and polysomnography in 95 participants. Results: Of the 566 participants, 128 (22.61%) had PSQI ≥5, reflecting poor sleep quality. A higher use of mobile phone was significantly associated with a poor sleep quality as a component of PSQI questionnaire (P=0.01) and higher overall PSQI score (P=0.01). The latency from sleep onset to N2 and N3 sleep stages was significantly shorter in participants having a higher mobile phone usage as compared to those with a lower usage [Median (range): 13.5 min (1.5-109) vs. 6.5 min (0-89); P=0.02] and [Median (range): 49 min (8.5-220.5) vs. 28.75 min (0-141); P=0.03], respectively. Interpretation & conclusions: This study focused on the maladaptive changes brought on by mobile phone usage on sleep. More studies with larger sample sizes need to be done that may serve to confirm the hypothesis generating findings of our study.

RESUMO

The Coronavirus Disease (COVID-19) is sweeping around the world at a rapid pace resulting in severe health crises across the globe. The pandemic condition has forced the government, regulatory authorities, bio/pharmaceutical industry, and healthcare system to take novel measures to address the crisis. The race for development of medicines and vaccines for treatment of COVID-19 is well under way and regulatory authorities are making efforts to safely deliver it into hands of public. As ever, pharmacopoeias played an active role in providing a framework of standards for the development, manufacturing, and quality of life-saving COVID-19 related medicines. The COVID-19 crisis has compelled the pharmacopoeias to redefine their role and show unprecedented levels of flexibility in extending their services to the stakeholders, developing new drug standards, and simultaneously ensuring the safety of their staff. During this pandemic, pharmacopoeias operated in a triangular chain system with regulators and pharmaceutical manufacturers to evaluate potential products for treatment of COVID-19. The present article provides an insight on the roles, challenges, and responses of the pharmacopoeias to deal with the current situation due to COVID-19 and emphasizes on new opportunities for collaborations to set standards for COVID-19 related drugs.

RESUMO

BACKGROUND & OBJECTIVES: : The fluoroquinolones (FQs) group of antibiotics is the backbone drugs for the management of drug-resistant tuberculosis (TB). In routine clinical practice, drug susceptibility testing (DST) for FQs is not performed, and the patients are empirically treated. A limited information exists regarding FQs resistance among pulmonary TB cases. The present study was conducted to determine the FQs resistance among drug sensitive and drug-resistant pulmonary TB patients in a tertiary care centre in north India. METHODS: : A total of 1619 sputum/smear-positive specimens of pulmonary TB patients were subjected to DST for first-line drugs (FLDs) and second-line drugs. In addition, FQs DST was also performed using automated Mycobacterial Growth Indicator Tube-960 liquid culture technique. The immuno-chromatographic assay was performed to distinguish Mycobacterium tuberculosis complex (MTBC) from non-MTBC. RESULTS: : Mycobacterium tuberculosis (Mtb) was isolated in 1499 sputum specimens; 1099 culture specimens were sensitive to FLDs, 249 grew as multidrug-resistant (MDR) Mtb and the remaining 151 isolates revealed any drug resistance to FLDs. While FQs monoresistance among the FLD sensitive isolates was 3.1 per cent (35/1099), 27.3 per cent (68/249) among MDR Mtb isolates had additional FQs resistance. INTERPRETATION & CONCLUSIONS: : FQs resistance among drug sensitive and MDR Mtb isolates was high in Delhi, India. Based on these findings, it is recommended that the DST for FQs should be routinely performed to avoid further amplification of drug resistance.

RESUMO

Background & objectives: The burden of non-tuberculous mycobacterial (NTM) disease is increasing worldwide. The disease shares clinicoradiological features with tuberculosis (TB), Nocardia and several fungal diseases, and its diagnosis is frequently delayed. The present study was performed to determine the frequency of NTM disease among TB suspects in a tertiary care centre in north India. Methods: In this prospective study, mycobacterial culture isolates from pulmonary and extrapulmonary specimens among TB suspects were tested with immunochromatographic assay (ICA). All ICA-negative isolates were considered as NTM suspects and further subjected to 16S-23S rRNA internal transcribed spacer gene sequencing for confirmation and species identification. Patients with active disease were treated with drug regimen as per the identified NTM species. Follow up of patients was done to determine clinical, radiological and microbiological outcomes. Results: Of the 5409 TB suspects, 42 (0.77%) were diagnosed with NTM disease. Patients with active disease consenting for treatment were treated and followed up. Thirty four patients had NTM pulmonary disease (NTM-PD) and the remaining eight had extrapulmonary NTM (EP-NTM) disease. Mycobacterium intracellulare and M. abscessus, respectively, were most frequently isolated from NTM-PD and EP-NTM patients. Fifteen NTM-PD and seven EP-NTM patients successfully completed the treatment. Ten patients died due to unrelated causes, five were lost to follow up and another four declined the treatment. Interpretation & conclusions: Our study showed that the frequency of NTM disease was low among TB suspects at a large tertiary care centre in north India and this finding was similar to other Indian studies. More studies need to be done in other parts of the country to know the geographical variation in NTM disease, if any.

RESUMO

Narcolepsy is a common sleep disorder in Western countries but rarely reported from India. Here, we report a small case series of four narcolepsy patients seen over a four year period in the sleep clinic of a tertiary care hospital in north India. The diagnosis was established by clinical history and two or more sleep-onset rapid eye movements (SOREMs) on multiple sleep latency tests (MSLTs) following overnight polysomnography (PSG). The mean age of patients was 26.2±6.4 yr; one patient had associated cataplexy and another one had all four cardinal symptoms of narcolepsy. All these patients had a history of excessive daytime sleepiness (EDS). The mean body mass index was 24.2±4.7 kg/m[2]. The mean sleep latency during MSLT was 2.7±1.3 min, and the mean REM latency was 5.7±2.9 min. Narcolepsy, although rarely reported from India, should be suspected in young non-obese patients complaining of EDS and confirmed by performing MSLT following overnight PSG.

RESUMO

INTRODUCTION: Type 2 diabetes mellitus (T2DM) has attained epidemic proportions and continues to increase despite the availability of a number of oral antidiabetic medications and major advances made in insulin delivery since its discovery nearly a hundred years ago. One, amongst many other reasons responsible for the inability to achieve adequate glycaemic control in a substantial proportion of T2DM patients is the delayed initiation and inappropriate intensification of insulin treatment. Appropriate initiation and intensification of insulin is critical for the successful achievement of tight glycaemic control. OBJECTIVE: To provide simple and easily implementable guidelines to primary care physicians on basal insulin initiation and intensification, along with use of basal insulin in special situations (hepatic failure, renal failure and gestational diabetes mellitus). METHODS: Each consensus statement on basal insulin initiation, intensification and use of basal insulin in special situations was evaluated for dosing and titration based on established guidelines, data from approved pack inserts, prescribing information or summary of product characteristics for each insulin type, and published scientific literature. These evaluations were then factored into the national context based not only on the clinical experience of the expert committee representatives' but also based on the common therapeutic practices followed in India to successfully achieve optimal glucose control. RESULTS: Recommendations on initiation and intensification of basal insulin, and its use in special situations, have been developed. The key recommendations are to initiate basal insulin when 2 or 3 oral antidiabetic medications fail to achieve target glycaemic control, or in symptomatic patients with glycated haemoglobin value greater than 9%. Depending upon patient characteristics, any of the four available basal insulins [Neutral protamine Hagedorn (NPH), Glargine (IGlar), Detemir (IDet), Degludec (IDeg)] can be used. However, IDeg has a longer duration of action, comparatively lesser hypoglycaemia (both overall and nocturnal) and more flexibility in administration timing compared to IGlar) and IDet. Inability to maintain glycaemic control should lead to prompt intensification of basal insulin treatment by adding mealtime insulin, consisting of one to three injections of either rapid-acting insulin analog or regular insulin; depending upon patient characteristics, intensification can also be achieved by transition from basal insulin to twice daily premixed insulin analogs/premixed human insulin/insulin co-formulations. IDeg/IDet can be used in all grades of renal and hepatic impairment; and IDet has been approved for use in gestational diabetes mellitus. CONCLUSIONS: We hope that these consensus based recommendations shall be a useful reference tool for health care practitioners and help them in initiating and intensifying insulin therapy in T2DM patients in order to achieve optimal glycaemic control.

RESUMO

Background: Tuberculosis (TB) and malnutrition are major global health problems, with multidrug-resistant (MDR) TB complicating international efforts. The role of vitamin D in susceptibility to and as an adjunctive treatment for TB is being studied extensively, although no study has included MDR-TB patients in context to dietary profile with vitamin D levels and sunlight exposure.Objective: This study aimed to estimate vitamin D serum levels and examine their association with dietary intake of vitamin D and sun exposure in patients with MDR-TB.Methods: North Indian participants were enrolled in three groups: MDR-TB, drug-susceptible pulmonary TB (DS-PTB), and healthy controls. All consenting participants underwent the estimation of macro- and micronutrient intake and sunlight exposure using structured questionnaires. Serum biochemistry, including 25-hydroxyvitamin D and calcium levels, was measured, and the correlation between variables was determined.Results: 747 participants were enrolled. Significant differences among the three groups were found in mean serum 25-hydroxyvitamin D levels, body mass index, macronutrient intake, dietary vitamin D and calcium content, and sun exposure index (SEI). All except sun exposure (SEI was highest in DS-PTB patients) were found to follow the trend: MDR-TB < DS-PTB < healthy controls. The mean serum vitamin D levels of all groups were deficient and correlated positively with dietary intake and SEI.Conclusion: In this study's we found significant association of serum vitamin D concentrations, dietary intake and sunlight exposure in MDR-TB, DS-PTB patients and healthy controls. Dietary intake may be more important than sun exposure in determining serum levels. However, the significance of this finding is uncertain. Further studies are required to confirm the association, direction, and potential for vitamin D supplementation to treat or prevent MDR-TB infection.

RESUMO

BACKGROUND AND AIMS: Most guidelines recommend protein restriction in adults with chronic kidney disease (CKD), with or without diabetes. However, advising protein restriction for every person with CKD is controversial. We aim to arrive at a consensus on this topic, especially among Indian adults with CKD. METHODS: A systematic literature search in the PubMed electronic database was undertaken using specific keywords and MeSH terms until May 1, 2022. All the retrieved literature was circulated and rigorously deliberated upon by the panel members. RESULTS: Seventeen meta-analyses that evaluated the outcomes of protein restriction in adults with CKD, with or without diabetes, met our inclusion criteria and were analyzed. A low-protein diet (LPD) in people with stages 3-5 of CKD (who are not on haemodialysis [HD]) reduces the severity of uremic symptoms and the rate of decline in glomerular filtration rate, leading to a delay in dialysis initiation. However, LPD in patients on maintenance HD may not be desirable because HD-induced protein catabolism may lead to protein-energy malnutrition. Since the average protein intake among Indians is much lower than recommended, this must be taken into consideration before recommending LPD for all Indian adults with CKD, particularly those on maintenance HD. CONCLUSION: It is essential to assess the nutritional status of people with CKD, particularly in countries like India where average daily protein intake is poor, before recommending guideline-directed protein restriction. The prescribed diet, including the quantity and quality of proteins, should be tailored to the person's habits, tastes, and needs.

RESUMO

Xpert MTB/RIF-generated cycle-threshold (C(T)) values have poor clinical utility as a rule-in test for smear positivity (cut-point ≤20.2; sensitivity 32.3%, specificity 97.1%) but moderately good rule-out value (cut-point >31.8; negative predictive value 80.0%). Thus, 20% of individuals with C(T) values >31.8 were erroneously ruled out as smear-negative. This group had a significantly lower sputum bacillary load relative to correctly classified smear-positive patients (C(T) ≤ 31.8; P < .001). These data inform on public health and contact tracing strategies.

RESUMO

Information regarding the utility of adjunct diagnostic tests in combination with Xpert MTB/RIF (Cepheid, Sunnyvale, CA, USA) is limited. We hypothesised adjunct tests could enhance accuracy and/or reduce the cost of tuberculosis (TB) diagnosis prior to MTB/RIF testing, and rule-in or rule-out TB in MTB/RIF-negative individuals. We assessed the accuracy and/or laboratory-associated cost of diagnosis of smear microscopy, chest radiography (CXR) and interferon-γ release assays (IGRAs; T-SPOT-TB (Oxford Immunotec, Oxford, UK) and QuantiFERON-TB Gold In-Tube (Cellestis, Chadstone, Australia)) combined with MTB/RIF for TB in 480 patients in South Africa. When conducted prior to MTB/RIF: 1) smear microscopy followed by MTB/RIF (if smear negative) had the lowest cost of diagnosis of any strategy investigated; 2) a combination of smear microscopy, CXR (if smear negative) and MTB/RIF (if imaging compatible with active TB) did not further reduce the cost per TB case diagnosed; and 3) a normal CXR ruled out TB in 18% of patients (57 out of 324; negative predictive value (NPV) 100%). When downstream adjunct tests were applied to MTB/RIF-negative individuals, radiology ruled out TB in 24% (56 out of 234; NPV 100%), smear microscopy ruled in TB in 21% (seven out of 24) of culture-positive individuals and IGRAs were not useful in either context. In resource-poor settings, smear microscopy combined with MTB/RIF had the highest accuracy and lowest cost of diagnosis compared to either technique alone. In MTB/RIF-negative individuals, CXR has poor rule-in value but can reliably rule out TB in approximately one in four cases. These data inform upon the programmatic utility of MTB/RIF in high-burden settings.

RESUMO

PURPOSE: Syndrome Z is the occurrence of metabolic syndrome (MS) with obstructive sleep apnea. Knowledge of its risk factors is useful to screen patients requiring further evaluation for syndrome Z. METHODS: Consecutive patients referred from sleep clinic undergoing polysomnography in the Sleep Laboratory of AIIMS Hospital, New Delhi were screened between June 2008 and May 2010, and 227 patients were recruited. Anthropometry, body composition analysis, blood pressure, fasting blood sugar, and lipid profile were measured. MS was defined using the National Cholesterol Education Program (adult treatment panel III) criteria, with Asian cutoff values for abdominal obesity. RESULTS: Prevalence of MS and syndrome Z was 74% and 65%, respectively. Age, percent body fat, excessive daytime sleepiness (EDS), and ΔSaO(2) (defined as difference between baseline and minimum SaO(2) during polysomnography) were independently associated with syndrome Z. Using a cutoff of 15% for level of desaturation, the stepped predictive score using these risk factors had sensitivity, specificity, positive predictive value, and negative predictive value of 75%, 73%, 84%, and 61%, respectively for the diagnosis of syndrome Z. It correctly characterized presence of syndrome Z 75% of the time and obviated need for detailed evaluation in 42% of the screened subjects. CONCLUSIONS: A large proportion of patients presenting to sleep clinics have MS and syndrome Z. Age, percent body fat, EDS, and ΔSaO(2) are independent risk factors for syndrome Z. A stepped predictive score using these parameters is cost-effective and useful in diagnosing syndrome Z in resource-limited settings.

RESUMO

The present study was designed to evaluate the quality control parameters, quantitative phytochemical analysis (total phenols, total flavonoids, and total saponin content), and the antiobesity effect of ethanol extract of Achyranthes aspera Linn. seed (EAA) by employing in vitro and in vivo models. In in vitro study, the inhibitory activity of EAA on pancreatic amylase and lipase was measured. The in vivo pancreatic lipase activity was evaluated by measurement of plasma triacylglycerol levels after oral administration of EAA along with lipid emulsion to Swiss albino mice. The EAA inhibited pancreatic amylase and lipase activity in vitro and elevations of plasma triacylglycerol level in mice. Furthermore, the antiobesity effect of EAA (900 mg/kg) was assessed in mice fed a high-fat diet with or without EAA for 6 weeks. EAA significantly suppressed the increase in body, retroperitoneal adipose tissue, liver weights, and serum parameters, namely; total cholesterol, total triglyceride, and LDL-cholesterol level. The anti obesity effects of EAA in high-fat-diet-treated mice may be partly mediated through delaying the intestinal absorption of dietary fat by inhibiting pancreatic amylase and lipase activity. Histopathological effects of EAA on the liver of mice were also assessed.

RESUMO

BACKGROUND: Obesity is recognized as a social problem, associated with serious health risks and increased mortality. Numerous trials have been conducted to find and develop new anti-obesity drugs through herbal sources to minimize side effects associated with the present anti-obesity drugs. The present study was designed to evaluate the quality control parameters, quantitative phytochemical analysis (total phenolic, total flavonoids and total saponin content), and the anti-obesity effect of lyophilized juice (LJ) of Stellaria media (Linn.) Vill. by employing in vitro and in vivo models. METHODS: In vitro studies were performed to evaluate the inhibitory activity of LJ on pancreatic amylase and lipase. The in vivo pancreatic lipase activity was evaluated by measurement of plasma triacylglycerol levels after oral administration of lipid emulsion to swiss albino mice. Furthermore, the anti-obesity effect of LJ was assessed at two doses, 400 mg/kg and 900 mg/kg body weight in mice fed a high-fat-diet with or without LJ for 6 weeks. RESULTS: The LJ inhibited pancreatic amylase and lipase activity in vitro and elevated plasma triacylglycerol level in mice. LJ suppressed the increase in body weight, retroperitoneal adipose tissue, liver weights and serum parameters viz., total cholesterol, total triglyceride, LDL-cholesterol level at the dose of 900 mg/kg body weight of the mice fed with high fat diet. The total phenolic, flavonoid and saponin contents were found to be 0.26 mg/g, 1.4 mg/g and 1.19 µg/g respectively of LJ. CONCLUSION: The anti-obesity effects of LJ in high-fat-diet fed mice may be partly mediated through delaying the intestinal absorption of dietary fat and carbohydrate by inhibiting digestive enzymes.

RESUMO

There are approximately 28 species of Aerva genus, but only a few species are medicinal of which A. persica, A. lanata and A. javanica are of great value. A number of flavonol glycosides (e.g., aervanone, kaempferol-3-galactoside, isorhamnetin-3-O-ß-D-glucoside) have been reported from Aerva persica as major phytoconstituents and the minor constituents are ß-cyanins (glycine betaine and trigonelline), sterols and carbohydrates. This plant is used as medicinal herb in several traditional systems of medicine all over the world, like diuretic, demulcent, purgative, emetic and tinder. Aerva plants are used to cure ulcer, lithiasis, dropsical affections, eye affection, toothache, headache, in disorders of abdomen and inflammation of internal organs. Roots and flowers are reported to possess hypoglycemic, antioxidant, anthelmintic, analgesic, antimalarial, antivenin activities and medicinal properties against rheumatism and kidney troubles.

RESUMO

BACKGROUND AND AIMS: The rapid increase in burden of type 2 diabetes mellitus (T2DM), poses a huge medico-economic challenge, especially when the cost of care is funded by out-of-pocket expenses. The aim of this review is to highlight various issues associated with rising cost of insulin, prevalence of cost-related insulin underuse, insulin related cost-saving behaviors, and viable solutions for the benefit of patients with T2DM receiving insulin. METHODS: Electronic databases (PubMed and Google Scholar) from 2000 to 2020 were searched using the key terms uncontrolled diabetes mellitus, insulin therapy, glycemic control, direct cost, indirect cost, out-of-pocket expenses, cost-related insulin underuse, cost-saving behaviors, and biosimilar insulin in developed countries and India. RESULTS: In majority of the patients with T2DM on monotherapy, addition of another oral antidiabetic agent is required. Despite these measures, the target glycemic goals are not achieved in majority of the patients resulting in various complications. These complications can be prevented and target glycemic goals can be achieved with early initiation of insulin therapy. However, rising cost is a major deterrent to the lifelong use of insulin. This results in non-compliance and further deterioration of glycemic control. Recently, biosimilar insulins have revolutionized the management of T2DM and look promising from the economic point of view. CONCLUSIONS: Biosimilar insulins are likely to further enhance the compliance of patients and should be used whenever feasible in patients with DM. However, the patient, along with prescriber should be allowed to make shared, informed decisions regarding the insulin they wish to use.
