Animal venoms are a complex mixture of highly specialized toxic molecules. Among them, pore-forming proteins (PFPs) or toxins (PFTs) are one of the major disease-causing toxic elements. The ability of the PFPs in defense and toxicity through pore formation on the host cell surface makes them unique among the toxin proteins. These features made them attractive for academic and research purposes for years in the areas of microbiology as well as structural biology. All the PFPs share a common mechanism of action for the attack of host cells and pore formation in which the selected pore-forming motifs of the host cell membrane-bound protein molecules drive to the lipid bilayer of the cell membrane and eventually produces water-filled pores. But surprisingly their sequence similarity is very poor. Their existence can be seen both in a soluble state and also in transmembrane complexes in the cell membrane. PFPs are prevalent toxic factors that are predominately produced by all kingdoms of life such as virulence bacteria, nematodes, fungi, protozoan parasites, frogs, plants, and also from higher organisms. Nowadays, multiple approaches to applications of PFPs have been conducted by researchers both in basic as well as applied biological research. Although PFPs are very devastating for human health nowadays researchers have been successful in making these toxic proteins into therapeutics through the preparation of immunotoxins. We have discussed the structural, and functional mechanism of action, evolutionary significance through dendrogram, domain organization, and practical applications for various approaches. This review aims to emphasize the PFTs to summarize toxic proteins together for basic knowledge as well as to highlight the current challenges, and literature gap along with the perspective of promising biotechnological applications for their future research., (© 2023.

Lignocellulosic biomass (LCB) has been a lucrative feedstock for developing biochemical products due to its rich organic content, low carbon footprint and abundant accessibility. The recalcitrant nature of this feedstock is a foremost bottleneck. It needs suitable pretreatment techniques to achieve a high yield of sugar fractions such as glucose and xylose with low inhibitory components. Cellulosic sugars are commonly used for the bio-manufacturing process, and the xylose sugar, which is predominant in the hemicellulosic fraction, is rejected as most cell factories lack the five‑carbon metabolic pathways. In the present review, more emphasis was placed on the efficient pretreatment techniques developed for disintegrating LCB and enhancing xylose sugars. Further, the transformation of the xylose to value-added products through chemo-catalytic routes was highlighted. In addition, the review also recapitulates the sustainable production of biochemicals by native xylose assimilating microbes and engineering the metabolic pathway to ameliorate biomanufacturing using xylose as the sole carbon source. Overall, this review will give an edge on the bioprocessing of microbial metabolism for the efficient utilization of xylose in the LCB., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Introduction: Tinea capitis (TC) is a common fungal infection of the scalp, especially in children. Trichoscopy is a noninvasive technique that allows rapid and magnified in vivo observation of the hair with the visualization of morphologic features that are often imperceptible to the naked eye., Aim: This study aimed to evaluate the usefulness of trichoscopy in clinical diagnosis and to study various clinico-morphological patterns of TC., Materials and Methods: This cross-sectional, observational study included 140 clinically diagnosed cases of TC seen during a period of 1 year (April 2021 to March 2022). All patients were evaluated using a dermoscope (DermLite DL4 Multispectral 3 Gen, San Juan Capistrano, CA, USA,10×)., Results: The prevalence rate of TC in this study was 2.69 per thousand population. The most common clinical variant was gray patch followed by kerion and black dot, and the most common etiological agent was Trichophyton tonsurans . The characteristic trichoscopic features were as follows: comma hairs (80%), followed by corkscrew hairs (68.6%), bent hairs (54.2%), zigzag hairs (35.7%), and morse code-like hairs (15%). Other findings included scaling (89.2%), followed by black dot (67.1%), broken hairs (42.8%), and crusting and pustules (32.1% each). Comma and corkscrew-shaped hairs were most common in the black dot type, whereas zigzag, bent hairs, and morse code hairs were common in the gray patch type of TC. There was a significant association between trichoscopic findings and type of TC., Conclusion: Trichoscopy can be considered a novel tool for rapid diagnosis and selection of the appropriate therapy and in the monitoring of treatment efficacy in TC., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Indian Dermatology Online Journal.)

Purpose of Review: Benzodiazepines, due to their anxiolytic properties, are prescribed to reduce anxiety and insomnia. They might have hypotensive effect via potentiation of the inhibitory effect of gamma-amino butyric acid (GABA) in the central nervous system and vasodilatory properties. However, studies comparing the effect of benzodiazepines in lowering blood pressure (BP) are equivocal. This systematic review and meta-analysis was planned to assess the efficacy of benzodiazepines in reducing blood pressure in short term among hypertensive patients., Recent Findings: Various trials and retrospective analysis conducted previously have reported that benzodiazepines cause short- as well as long-term BP reduction in patients with increased anxiety with hypertension. On the other hand, several studies investigating the efficacy of benzodiazepines in patients with hypertension have reported inconclusive results. The primary question about the effect of benzodiazepines in lowering BP remains unanswered. In this meta-analysis of seven studies, benzodiazepines were found comparable to standard drugs in reducing systolic and diastolic BP in patients having hypertension. Although, the mean difference in systolic BP with benzodiazepines and placebo was statistically not significant, the difference can be considered as clinically meaningful. The current review offers preliminary evidence that benzodiazepines may have antihypertensive properties and may be used as add-on antihypertensive in a subset of patients in short term. The existing data are encouraging, but more clinical trials and mechanistic research are required to ascertain the long-term benefits., (© 2023.

Exosomes, a subpopulation of Extracellular vesicles (EVs), are cell-secreted vesicles found in the majority of biological fluids, including breast milk, tears, sweat, blood and, urine. The density and size of these vesicles depend on a variety of factors, including age, gender and the biological condition of the individual. Researchers are now focusing on the selective extraction of exosomes from bodily fluids due to the unique biomolecule composition of exosomes, which is critical for diagnosis, disease, and regeneration. Furthermore, current approaches for exosome isolation have limitations, necessitating the development of a simpler and more effective technique to achieve this goal. In this study, we investigated a quick and effective strategy for isolating exosomes from serum using a bench-top centrifuge. This was accomplished by raising antibodies against exosome surface tetraspanins (CD9, CD63 & CD81) in Leghorn chickens due to their phylogenetic distance from humans and cost-effectiveness for commercial use. In order to separate exosomes from a complex biological fluid, the antibodies were further coupled with gold nanoparticles (AuNPs). The findings were validated using ELISA, spectrophotometry, and transmission electron microscopy (TEM). Using this technique, exosome isolation from serum was achieved rapidly and these were captured by using anti CD63 antibodies bound to AuNPs. To summarize, exosomes were purified from serum using anti-CD63 antibodies conjugated to gold nanoparticles (IgY@AuNPs). Consequently, the approach for exosome isolation from biological fluid could be useful for clinically monitoring the biological state of the patients., (© 2023.

Pyrazole and sulfonamide constitute an important class of drugs, with several types of pharmacological agents. Facile synthesis of two new series of 3,5-dimethyl-1 H -pyrazole-4-sulfonamide and 1,3,5-trimethyl-1 H -pyrazole-4-sulfonamide derivatives was designed and synthesized. These pyrazole-4-sulfonamide derivatives are characterized by Fourier transform infrared (FT-IR), 1 H NMR, 13 C NMR, and elemental analysis, and their biological evolution data are presented. This paved way for the development of new pyrazole-4-sulfonamide derivatives. These compounds are tested for their in vitro antiproliferative activity against U937 cells by the CellTiter-Glo Luminescent cell viability assay using Mitomycin C. Cytotoxicity detection is based on the measurement of LDH activity, while these compounds did not exhibit cytotoxic activity on these cells. Half maximal inhibitory concentration (IC 50 ) was calculated by Graph Pad Prism software for each dose. Their structure-activity relationships were obtained and discussed., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

Background Despite acne being a common dermatological problem, there is a paucity of literature addressing the knowledge, attitude and practice about it. Aims/Objectives To find out what patients know about acne, its cause and treatment, as well as myths, misconceptions and attitude towards it. Methods A cross-sectional, descriptive questionnaire-based study on acne patients at Maharana Bhupal Hospital, RNT Medical College, Udaipur, Rajasthan, India. Results Most (84.8%) patients belonged to the age group of 16-25 years. The majority (63.9%) presented 12 months after the onset of acne. More than half had average knowledge, a positive attitude and good practices, related significantly to gender and education. Limitations A standardized questionnaire suitable for all dialects and regional languages would have yielded more uniform results. Conclusion Study revealed that acne patients still need to acquire accurate, adequate and easily accessible information to seek timely and appropriate treatment, and alleviate their psychological suffering.

Small, strained ring molecules of phenylcyclopropane carboxamide have rigid, defined conformations and unique electronic properties. For these reasons many groups, seek to use these subunits to form biologically active compounds. Herein we report a generally applicable approach for preparing a small cyclopropane ring containing 1-phenylcyclopropane carboxamide derivatives to a wide range of the different aromatic compounds by α-alkylation of 2-phenyl acetonitrile derivatives with 1, 2-dibromo ethane in good yields followed by the conversion of cyano group to acid group by the reaction with concentrated hydrochloric acid. This obtained acid derivative undergoes acid amine coupling with various Methyl 2-(aminophenoxy)acetate to form 1-Phenylcyclopropane Carboxamide. These compounds possess distinct effective inhibition on the proliferation of U937, pro-monocytic, human myeloid leukaemia cell line while these compounds did not show cytotoxic activity on these cells. The structure-activity relationships of these compounds are discussed., (© 2023 The Authors.)

Emerging hypotheses in the pathophysiology of major depressive disorder (MDD) suggest important role of neurotrophic factors and oxidative stress. This study assessed the effect of milnacipran (a dual serotonin‑noradrenaline reuptake inhibitor) on brain‑derived neurotrophic factor (BDNF) and oxidative stress biomarkers i.e., malondialdehyde (MDA), glutathione‑s‑ transferase (GST) and glutathione reductase (GR) in patients of MDD. Thirty patients (aged 18 to 60 years) with MDD diagnosed by DSM‑IV criteria, with Hamilton Depression Rating scale (HAM‑D) score ≥ 14 were included in the study. Patients were given milnacipran in the doses of 50‑100 mg once daily. Patients were followed up for 12 weeks. HAM‑D score at the start of treatment was 17.8±1.7 which significantly reduced to 8.9±3.1 at 12 weeks of treatment. In responders, the plasma BDNF levels increased significantly at 12 weeks post treatment. There was no significant change in the pre‑ and post‑treatment values of oxidative stress parameters (MDA, GST and GR) after 12 week treatment. Milnacipran is effective and well tolerated in MDD patients, and its therapeutic response is associated with an increase in plasma BDNF levels. However, milnacipran did not affect oxidative stress biomarkers.

As we were on the road to recovery from the coronavirus disease-19 (COVID-19) pandemic, the world is waking up to yet another potential adversary. Monkeypox (or human monkeypox) caused by monkeypox virus (an orthopox virus) is fast emerging in more than 80 countries worldwide, where it has never been historically reported. We in India, have already seen the advent of this outbreak since July 2022, with a progressive rise in number of cases being seen. Though the virus is not a novel virus; it is presenting with atypical manifestations as compared to our conventional knowledge of the disease. Through this document, the Indian Association of Dermatologists, Venereologists, and Leprologists Academy aims to sensitize dermatologists toward recognizing the clinical features and responding promptly, to contain the outbreak at the earliest. In view of the non-availability of specific antiviral drugs as well as vaccines; early detection, isolation, and prevention of spread form the mainstay of our approach towards the outbreak, which has been declared to be a "Public Health Emergency of International Concern" by the World Health Organization., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Indian Dermatology Online Journal.)

Background: Acute seizure activity might cause complications including bodily harm, progression to status epilepticus, and poor quality of life in children. The introduction of a venous line may be difficult in children with seizures which would delay the initiation of treatment. Rectal drug administration can be socially awkward for patients and providers. Intranasal (IN) midazolam offers a valuable substitute that is easier and faster to administer., Objective: To assess the efficacy, safety, and acceptability of intranasal midazolam in children with acute seizure when compared to conventional IV or rectal benzodiazepine (BDZ)., Methods: PubMed, google scholar, websites clinicaltrials.gov and the WHO-international clinical trials registry platform, were searched. Randomized controlled/prospective randomized trials comparing IN midazolam against IV/rectal BDZ in the treatment of acute seizures in pediatric patients were included in the meta-analysis., Results: Data of 10 studies were quantitatively analyzed. Intranasal midazolam (n = 169) when compared to IV/rectal BDZ (n = 161) has a shorter interval between hospital arrival and seizure cessation {(mean difference = -3.51; 95% CI [-6.84, -0.18]) P = 0.04}. Regarding time to seizure cessation after midazolam (n = 326) or BDZ (n = 322) administration, there is no significant difference between the two groups {(mean difference = -0.03; 95% CI [-1.30, 1.25]), P = 0.97} and both are equally effective for controlling acute seizures (odds ratio = 1.06; 95% CI [0.43, 2.63]; n = 737)., Conclusion: In children with acute seizures, IN midazolam is equally effective in aborting seizure and decreases the total time from hospital arrival and cessation of seizures, eventually leading to faster cessation of seizure as compared to IV/rectal BDZ., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Inc.

Background: Emerging hypotheses in the pathophysiology of major depressive disorder (MDD) indicate the role of neurotrophic factors and inflammation. This study assessed the association between therapeutic response of bupropion and serum brain-derived neurotrophic factor (BDNF) and tumour necrosis factor-α (TNF-α) levels in patients with MDD., Methods: Thirty patients (aged 18 to 60 years) with MDD diagnosed by DSM-5 criteria, with Hamilton Depression Rating scale (HAM-D) score ≥ 20 were included in the study. Patients were given bupropion sustained release (SR) in the doses of 150 mg once daily. All patients were followed up for 12 weeks., Results: HAM-D score at the start of the treatment was 25.57 ± 1.85 which significantly reduced to 10.8 ± 4.24 at 12 weeks of treatment. The serum BDNF level increased significantly (p < 0.05) from 2.42 ± 0.19 ng/ml to 2.97 ± 0.10 ng/ml and the levels of serum TNF-α reduced significantly (p < 0.05) from 4.45 ± 0.95 pg/ml to 2.11 ± 0.84 pg/ml at 12 weeks of treatment, in responders to treatment., Conclusion: The results of our study suggest that bupropion SR monotherapy is effective and well tolerated in MDD patients with moderate to severe depression, and its therapeutic efficacy is accompanied by an increase in serum BDNF levels and a decrease in serum TNF-α levels., (Copyright © 2020 Elsevier Inc.

Background: Vitiligo is an acquired, idiopathic, and common depigmentation disorder. The values of various epidemiologic parameters are often doubtful due to the methodological weaknesses of the studies., Aims: To elicit the magnitude of various epidemiological parameters and important correlates of vitiligo., Materials and Methods: Every vitiligo patient attending the outpatient department of medical colleges spread over most of the Indian states were examined over a period of 1 year. Various epidemiological and clinical variables were examined and compared with age and sex-matched controls (registered in the Clinical Trial Registry of India CTRI/2017/06/008854)., Results: A total of 4,43,275 patients were assessed in 30 medical colleges from 21 Indian states. Institutional prevalence of vitiligo was 0.89% (0.86% in males and 0.93% in females, P < 0.001). The mean age at presentation and mean age at onset were 30.12 ± 17.97 years and 25.14 ± 7.48 years, respectively. Head-neck was the most common primary site ( n = 1648, 41.6%) and most commonly affected site ( n = 2186, 55.17%). Most cases had nonsegmental vitiligo ( n = 2690, 67.89%). The disease started before 20 years of age in more than 46% of cases. About 77% of all cases had signs of instability during the last 1 year. The family history, consanguinity, hypothyroid disorders, and depressed mood were significantly ( P < 0.001) higher among the cases. First, second, and third-degree family members were affected in 269 (60.04%), 111 (24.78%), and 68 (15.18%) cases, respectively. Work-related exposure to chemicals was significantly higher among cases ( P < 0.008). Obesity was less common among vitiligo cases [ P < 0.001, odds ratio (OR) 0.78, 95% confidence interval (CI): 0.71-0.86]., Conclusion: This is one of the largest studies done on vitiligo in India. The prevalence of vitiligo was found to be 0.89% among hospital attendees. Prevalence of vitiligo was higher among females than in males and prevalence of family history, consanguinity, hypothyroid disorders were higher in vitiligo than among controls., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Indian Journal of Dermatology.)

Background and Aims: Monocyte chemoattractant protein-1 (MCP-1) and cathepsin-D are progressively raised in type 2 diabetes mellitus (T2DM) with both non proliferative and proliferative retinal disease. This study aimed to evaluate the effect of antidiabetic medications on MCP-1 and cathepsin-D., Methods: 60 patients of T2DM without retinopathy and 60 of diabetic retinopathy were enrolled to receive metformin (500 mg-1000 mg) combined with either glimepiride (1 mg-2 mg) or insulin. The effect of antidiabetic medications on serum MCP-1 and cathepsin-D was assessed., Results: Mean MCP-1 (pg/ml) and cathepsin-D (ng/ml) levels were significantly lower in patients of T2DM with and without retinopathy treated with metformin + insulin (468.52 ± 272.84 vs 234.30 ± 180.58; p < 0.01 and 460.15 ± 128.52 vs 517.33 ± 213.49; p = 0.214) as compared to patients treated with metformin + glimepiride (1434.02 ± 105.27 vs 1256.27 ± 76.76; p < 0.01 and 1689.36 ± 752.57 vs 919.69 ± 675.05; p = < 0.01). No significant correlation of MCP-1 and cathepsin-D with HbA1c, fasting and post prandial blood glucose were found., Conclusion: Patients treated with metformin and insulin combination had lower serum MCP-1 and cathepsin-D levels which suggests that this combination may be more effective in reducing the progression of diabetic retinopathy.

Background: Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening mucocutaneous drug reactions with a high morbidity and mortality that require immediate medical care. Several immunomodulatory drugs are used for the treatment but evidence of their efficacy is limited. Cyclosporine has recently been found to have a promising role in SJS/TEN owing to its potent antiapoptotic activity., Aims: This open label prospective study was conducted to determine the efficacy, safety, and tolerability of cyclosporine in patients with SJS/TEN., Methods: This study was conducted at a tertiary care teaching hospital of South Rajasthan during a period of 4 years (August 2015 to July 2019). Data regarding clinical profile, causative drug(s), disease severity, associated comorbidities, treatment received, and outcome were recorded in a predesigned proforma. SCORTEN prognostic score was calculated for each patient at the time of admission. Cyclosporine was administered in a dose of 5 mg/kg body weight in two divided dosage until reepithelization., Results: Out of 16 patients 10 were males and 6 were females. Mean age of patients was 30.62 ± 16.98 years (range: 7-63). Most of the patients, i.e., 8 out of 16 had TEN, 5 patients had SJS, and 3 patients had SJS/TEN overlap. Mean ± SD delay between onset and admission was 3.812 ± 1.377 days (range: 2-7). Among the suspected drugs, antiepileptics (43.7%) formed the major group. Mean duration of reepithelization was 10.5 ± 3.46 days (range: 7-15). Based on the SCORTEN, the expected mortality was 2.55 with mean predicted mortality rate of 16.43% with SD of 19.3., Limitations: 1) Sample size was small. 2) Placebo control trial could not be done due to the severity of the disease., Conclusion: We recommend cyclosporine (5 mg/kg/day) as the first line-specific immunomodulatory agent in SJS/TEN on account of its efficacy, safety, rapid reepithelization, decrease hospital stay, and reduced morbidity and mortality., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Indian Dermatology Online Journal.)

Introduction: Cutaneous leishmaniasis (CL) is a vector-borne protozoal infection of the skin with variable clinical manifestations. In Rajasthan, western Thar desert is endemic for this disease., Aim: The present study was aimed to describe clinico-epidemiological features of cutaneous leishmaniasis cases from a non-endemic area of South Rajasthan., Materials and Methods: A hospital-based prospective study was carried out during a period of 3 years (2017-2019). Data regarding clinical profile and treatment outcome were recorded in a predesigned proforma for analysis. Diagnosis of CL was made clinically and confirmed by demonstration of amastigotes in microscopic examination of Giemsa stained tissue smear of lesions., Results: Out of 24 patients, 16 (67%) were females and 8 (33%) were males. The age ranged from 3 months to 68 years (median-25). Face (67%) and extremities (29%) were the common sites affected. The most common morphological form was crusted plaques (54%) followed by nodular lesions (38%). Slit skin smear for Leishmania donovani bodies was positive in all patients (100%)., Conclusion: This study highlights a focus of CL in non-endemic areas of South Rajasthan. Of late leishmaniasis is breaking out of its classical boundaries and is increasingly being reported from new geographic locations with a possibility of a novel parasite variant. Therefore, a high clinical suspicion of CL should be kept in non-endemic area., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Indian Dermatology Online Journal.)

Objective: The reduction of Coenzyme Q10 (CoQ10) levels following statin use has been linked to cause peripheral neuropathy. Hence, this study was planned to explore the effect of statin on the serum HMGCR (3-hydroxy-3-methyl-glutaryl-coenzyme A reductase), serum CoQ10 levels and nerve conduction and their correlation., Patients and Methods: In an open labelled, cross-sectional, observational study, estimation of serum HMGCR and CoQ10 levels was performed in 50 atorvastatin/rosuvastatin users and 50 normal healthy volunteers (NHV). Statin users were also subjected to nerve conduction studies (NCS)., Results: Mean serum HMGCR level in NHV was higher (73.58 ± 7.64 ng/ml; p = 0.003) than that in statin users (49.11 ± 1.98 ng/ml). Similarly, mean serum CoQ10 levels was also lower (30.54 ± 2.03 ng/ml, p < 0.0001) in statin users than in NHV (49.43 ± 3.23 ng/ml). Amongst the 50 statin users, 29 had impaired NCS in sural, tibial and common peroneal nerve with lower mean serum CoQ10 levels (24.05 ± 1.96 ng/ml; p < 0.0001). Significant negative correlation was observed between onset time of action potential (AP) of the sural nerve and serum CoQ10 (r=-0.32) and HMGCR (r=-0.43) levels. There was significant positive correlation of conduction velocity of sural (r = 0.38) and tibial (r = 0.31) nerves with serum CoQ10 level. While conduction velocity in sural (r = 0.37) and common peroneal (r = 0.34) nerves positively correlated with serum HMGCR levels. The amplitude of the AP of the common peroneal nerve positively correlated with both serum CoQ10 (r = 0.52) and HMGCR (r = 0.46) levels., Conclusion: Statin users had lower serum CoQ10 and HMGCR levels associated with nerve conduction deficits suggesting a role of CoQ10 in the occurrence of the neurological adverse effects., (Copyright © 2020 Elsevier B.V.

Background Evidence from the literature, highlights the increased risk of developing glucose intolerance and type 2 diabetes mellitus (T2DM) with statin therapy. In addition, few animal studies demonstrate that adipsin secreted from adipocytes plays a crucial role in insulin secretion and the development of T2DM. Methods To further explore the role of serum adipsin, in this prospective open label study, 55 newly diagnosed dyslipidemic patients were enrolled. Before starting statin therapy, liver function test (LFT), kidney function test (KFT), lipid profile, glycemic parameters [glycated hemoglobin A (HbA1c), fasting blood sugar (FBS), and postprandial blood sugar (PPBS)], serum insulin, and serum adipsin were estimated. Then these patients were prescribed statin (i.e. atorvastatin, rosuvastatin, or pitavastatin) and after 12 weeks of therapy, all the above investigations were repeated. Results After 12 weeks of statin therapy, the LFT and KFT values remained unchanged and lipid parameters showed significant improvement. But the glycemic parameters deranged significantly (p < 0.001), i.e. FBS, PPBS, and HbA1c increased by 12.49% (102.99 ± 20.76 mg/dL), 24.72% (147.71 ± 47.29 mg/dL), and 21.43% (6.38 ± 1.34%), respectively. On the other hand, the baseline adipsin (2.73 ± 1.99 ng/mL) and insulin (16.13 ± 12.50 mIU/L) levels reduced significantly (p < 0.0001) to 1.43 ±1.13 ng/mL and 6.91 ± 5.93 mIU/L, respectively. The reduction in serum adipsin also showed a positive correlation with reduction in serum insulin (r = 0.85; p < 0.0001). None of the patients experienced any significant adverse effect or reaction leading to discontinuation of therapy. Conclusions There might be an association between reduction in adipsin and development of glucose intolerance by statin therapy.

Background It is imperative that non-compliance with statins be identified and addressed to maximize their clinical benefits. Patient self-reporting methods are convenient to apply in clinical practice but need to be validated. Objective We studied the concordance of a patient self-report method, Morisky eight-item medication adherence scale (MMAS)), with the pill count method in measuring adherence with statins and their correlation with extended lipid profile parameters and serum hydroxyl-methylglutaryl coenzyme A reductase (HMGCoA-R) enzyme levels. Methods MMAS and the pill count method were used to measure the adherence with statins in patients on statins for any duration. Patients were subjected to an estimation of extended lipid profile and serum HMGCoA-R levels at the end of three months follow-up. Results Out of a total of 200 patients included in the study, 117 patients had a low adherence (score less than 6 on MMAS) whereas 65 and 18 patients had medium (score 6 or 7) and high adherence (score of 8), respectively. The majority of patients who had low adherence to statins by MMAS were nonadherent by the pill count method yielding a concordance of 96.5%. Medium or high adherence to statins by the MMAS method had a concordance of 89.1% with the pill count method. The levels of total cholesterol, low-density lipoprotein-cholesterol, apolipoprotein B, and HMGCoA-R were negatively correlated with compliance measured by pill count and MMAS in a statistically significant way and with similar correlation coefficients. HMGCoA-R levels demonstrated a plateau phenomenon, with levels being 9-10 ng/ml when compliance with statin therapy was greater than 60% by pill count and greater than 6 on the Morisky scale. Conclusion In conclusion, MMAS and the pill count method showed concordance in measuring adherence to statins. These methods need to be explored further for their interchangeability as surrogates for biomarker levels., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Grover et al.)

Background: Periostin is an extracellular matrix protein, and its expression is upregulated in airway epithelial cells in patients with bronchial asthma. Periostin may be a key molecule linked to type 2 T-helper cell inflammation. Inhaled corticosteroids (ICS) may suppress periostin-induced asthmatic inflammation. This study estimated the serum periostin levels in patients with asthma and evaluated the effect of ICS on the levels of periostin, peak expiratory flow rate (PEFR), and quality of life (QOL). Methods: The study design was prospective, open label, and observational. Forty adults with mild-to-moderate bronchial asthma started on ICS and matched healthy controls were enrolled. The patients were evaluated for their serum periostin, PEFR, and QOL by using asthma QOL questionnaire scores at baseline and after 4 weeks. Results: The mean ± standard deviation (SD) serum periostin concentration in patients with asthma was 90.36 ± 19.81 ng/mL, which was significantly higher (p < 0.01) compared with healthy controls (31.88 ± 8.71 ng/mL). ICS treatment for 4 weeks reduced the mean ± SD serum periostin levels to 58.78 ± 14.53 ng/mL. The mean ± SD PEFR increased significantly, from 225.25 ± 60.79 L/min to 292.5 ± 59.18 L/min (p < 0.01), after 4 weeks. Similarly, the mean ± SD when using asthma QOL questionnaire scores significantly increased, from 40.7 ± 7.84 at baseline to 59.33 ± 11.0 on day 28 after ICS therapy (p < 0.01). Conclusion: The serum periostin level, a marker of allergic inflammation and remodeling, increased in bronchial asthma and was reduced with ICS therapy. ICS improved QOL scores and PEFR in patients with asthma.

Background: Cutaneous adverse drug reactions (CADRs) are probably the most frequent of all manifestations of drug sensitivity. As a considerable number of new drugs are periodically introduced into the market, the incidence of CADR is likely to increase. The pattern of CADR and the causative drugs is likely to change accordingly. There is no uniformly accepted and reliable method of objectively assessing the causal link between drug and adverse reaction., Aim: To study the clinical patterns and causative drugs and compare causality assessment [World Health Organization (WHO) and Naranjo algorithm] of CADR among patients attending the dermatology department., Materials and Methods: This is a cross-sectional hospital-based study in which all patients with suspected CADR attending the dermatology department of a tertiary care center over a 9-month period were evaluated using the causality assessment criteria recommended by the WHO-Uppsala Monitoring Centre (UMC) and Naranjo scale. The severity of the reaction was assessed using Adverse Drug Reaction Severity Assessment Scale (modified Hartwig and Siegel scale)., Results: A total of 200 consecutive patients with CADR were evaluated. The causality assessment for a drug as per WHO scale yielded 63 (31.5%) cases as certain, 12 (6%) as probable, and 125 (62.5%) as possible, whereas Naranjo scale showed 26 (13%) cases to be definite, 138 (69%) as probable, and 36 (18%) as possible. There was poor agreement between the two scales. Fixed drug eruption was the most common pattern of CADR (82.41%). The average number of drugs received by patients was 2.09. The most common suspected drug group was antimicrobials ( n = 170; 40.5%), followed by nonsteroidal anti-inflammatory drugs ( n = 148; 35.3%) and antiretroviral drugs ( n = 41; 9.7%). Fixed drug eruption was most commonly caused by paracetamol. Antiepileptics and antimicrobials were the most common suspects among severe cutaneous adverse reactions., Limitations: Multiple concomitant drug usage by patients and inability to provoke all patients/measure drug levels in blood resulted in higher number of drugs with causal association as probable/possible., Conclusion: WHO-UMC scale was found to be easier to apply and evaluate, with greater practical utility. Poor agreement between the two commonly used scales emphasizes the need for a consistent and uniform causality assessment tool., Competing Interests: There are no conflicts of interest.

Objective: Data regarding efficacy comparison of daily regimen (DR) versus every other day regimen (EODR) atorvastatin therapy is not validated by estimation of serum hydroxymethylglutaryl-CoA reductase (HMGCR) levels and HMGCR correlation with lipid indices., Methods: In this randomized controlled trial, we compared the efficacy of DR versus EODR by measuring lipid indices and serum HMGCR levels at baseline and after 12 weeks of 10 mg atorvastatin therapy. Primary endpoint was comparison of mean change in serum HMGCR levels and lipid indices of both groups and their correlation with each other. Secondary endpoints were assessed by estimating serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase MM (CK-MM) levels and adverse drug reactions (ADRs)., Results: A total of 61 patients were enrolled of which 46 completed the study (24 in DR vs 22 in EODR group). The mean reduction in total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) and non-high density lipoprotein-cholesterol (HDL-C) was significantly higher in DR group, whereas mean reduction in triglycerides (TG) and increase in HDL-C was similar in both the groups. Reduction in serum HMGCR levels was comparable in both the groups (31.17% vs 28.19%). Change in serum HMGCR levels correlated more with change in lipid indices of DR group. Also, safety parameters were similar between the two groups., Conclusion: Both the regimens achieved therapeutic goals, however DR was found to be superior as it achieved greater reduction in TC and LDL-C. Further, these findings are substantiated by correlation of lipid indices with serum HMGCR levels., (Copyright © 2018. Published by Elsevier B.V.)

Background: Recently, with better understanding of the immunology of warts, immunotherapeutic approaches have emerged as an effective treatment option for the management of cutaneous warts. Intralesional immunotherapy with MMR vaccine is one such modality but there are still lack of enough placebo-controlled studies., Aim: To evaluate the efficacy of intralesional MMR in patients of extragenital warts in a double-blinded manner using normal saline as control., Patients and Methods: One hundred patients of extragenital cutaneous warts were randomly allocated into two groups, the interventional (MMR) group and control (normal saline) group. MMR vaccine was injected intralesionally in the patients belonging to interventional group, a similar volume of normal saline (NS) was injected in the control group. The outcome in terms of treatment response, adverse effects, and recurrences were evaluated and compared., Results: Eighteen of thirty (60%) patients in the interventional group achieved complete response as against 7 (23.3%) in the control group ( P = 0.01). Distant warts cleared in 69.5% patients in the interventional groupcompared to none in the control group. Adverse effects seen in both groups were injection site pain and mild erythema. A total of 57.1% patients showed recurrences in the control group compared to 16.6% in the interventional group., Conclusion: Intralesional MMR vaccine is an effective treatment option in patients with multiple extragenital warts. It is suggested that it should be used as first-line therapy for multiple warts and a second-line therapy for warts recalcitrant to standard therapies., Competing Interests: There are no conflicts of interest.

Any drug can cause any rash! Cutaneous adverse drug reactions (CADRs) are great mimickers and can be included in the differential diagnosis of any inflammatory dermatoses. Several drugs can cause rash of similar morphology and the same drug can cause rash of different morphology. While some common and specific drug reaction patterns are recognized easily by the clinicians, many a times unusual and interesting patterns can be induced by drug(s), thus leading to erroneous diagnosis and mistreatment. This review aims to familiarize clinicians with some rare, yet interesting patterns of CADR., Competing Interests: There are no conflicts of interest. What is new? The presentation of cutaneous adverse drug reaction is not always typical. The clinician should therefore be familiar with unusual and rare presentations as well. Many drugs considered safe may cause adverse drug reactions, many of which may be serious.Many newer and targeted agents often believed to be safe, can have bizzare and unusual presentation of adverse drug reactions. A possibility of paradoxical drug reactions should be kept in mind when a primary disease gets worsened with a drug used to treat that disease; the examples include immune reconstitution inflammatory syndrome (IRIS) with antiretroviral therapy and induction and/or worsening of psoriasis by TNF-alpha inhibitors.

Evidence suggests that neurotrophic factors, inflammatory markers, and circadian rhythm dysfunctions could be involved in pathophysiology of major depressive disorder. This study evaluated the efficacy and tolerability of agomelatine, a melatonergic drug, and fluoxetine (positive comparator) and their effect on serum brain-derived neurotrophic factor (BDNF) and tumor necrosis factor (TNF)-α level in patients having major depressive disorder with severe depression. In the present study, we chose TNF-α and BDNF because reduction of TNF-α and rise in BDNF levels are linked with improvement in major depressive disorder. Patients with Hamilton Rating Scale for Depression (HAM-D) score ≥25 were treated with agomelatine or fluoxetine and followed up for 12 weeks. In the agomelatine group, the HAM-D score, BDNF level, and TNF-α level at the start of treatment were 31.1 ± 1.88 ng/mL, 2.44 ± 0.38 ng/mL, and 512.5 ± 86.2 pg/mL, respectively, which significantly changed to 13.67 ± 2.22 ng/mL, 2.87 ± 0.44 ng/mL, and 391.64 ± 104.8 pg/mL, respectively (P < .05 for all 3 measures), at 12 weeks. In the fluoxetine group, the HAM-D score, BDNF level, and TNF-α level at the start of treatment were 30.83 ± 2.60 ng/mL, 2.54 ± 0.37 ng/mL, and 554.14 ± 46.8 pg/mL, respectively, which significantly changed to 13.67 ± 1.79 ng/mL, 3.07 ± 0.33 ng/mL, and 484.15 ± 49.9 pg/mL, respectively (P < .05 for all 3 measures) at 12 weeks. The BDNF level was significantly increased posttreatment with both drugs, and TNF-α level fell significantly more with agomelatine compared to fluoxetine. Thus, chronic neuroinflammatory biomarkers contribute to circuitry dysregulation in depression. Trophic factors repair dysfunctional circuits in depression. Both treatments were found to be safe and well tolerated., (© 2017, The American College of Clinical Pharmacology.)
