Abstract
Parthenium hysterophorus is the commonest cause of plant dermatitis in India. It classically causes airborne contact dermatitis (ABCD), characterized by pruritic, eczematous, and lichenified lesions involving predominantly the face and flexural areas. Over time, however, a transition to chronic actinic dermatitis (CAD) pattern, with prominent involvement of sun-exposed sites, may occur. Management involves strict protective measures and topical and oral corticosteroids or immunomodulatory agents but often leads to only limited success. We report a patient with a chronic and extensive mixed ABCD-CAD pattern of parthenium dermatitis recalcitrant to conventional treatment, with rapid resolution after initiation of treatment with tofacitinib.

Abstract
Congress grass (Parthenium hysterophorus L., family Asteraceae) is found generally in agricultural and vacant lands across the globe. This study investigated the fatty acids and elemental profiles of different parts including roots, stem and leaves of P. hysterophorus in the response to seasonal variation. The elemental analysis and fatty acid were determined in both the winter and summer seasons. The root, stem, and leaves powder were subjected to extraction with acetone, water, chloroform, diethyl ether, ethanol, methanol, and n-hexane to measure the extractive values. Among all the plant parts, leaves recorded the highest extractive value of 29%, and 28% with acetone and diethyl ether, respectively, while the root recorded the lowest (10.3%) extractive value with chloroform. Higher concentrations of saturated and unsaturated fatty acids were detected in all the plant parts in the winter collection than in the summer season. Parthenium hysterophorus is multi medicinal applications such as used for rheumatic pain, urinary tract infections, inflammation, diarrhea, neuralgia, and malaria. The study highlights the importance of collection time (seasons) of different parts of P. hysterophorus for the maximum extraction of both elements and fatty acids either saturated or unsaturated from the pharmacogenetic point of view.

Biochemical Characterization of Different Chemical Components of Parthenium hysterophorus and Their Therapeutic Potential against HIV-1 RT and Microbial Growth. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3892352. [PMID: 35528165 PMCID: PMC9071890 DOI: 10.1155/2022/3892352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 03/21/2022] [Indexed: 11/17/2022]
Abstract
Parthenium hysterophorus possesses certain allelochemicals responsible for their medicinal effects. The presence of oils, polyphenols, alkaloids, terpenes, pseudoguaianolides, and histamines in P. hysterophorus has been shown to exhibit medicinal properties. However, the systematic biomedical properties of this plant are still unexplored. The extracts of leaves, stem, and flower of P. hysterophorus, both at low and high temperatures (equivalent to boiling points of different solvents) were prepared. The extracts prepared in hexane, ethylacetate, methanol, and water were analyzed spectrophotometrically and colorimetrically and resolved on TLC for the presence of phytochemicals. The analyses of the free radical quenching potential of plant extracts were done by DPPH assay. The total antioxidant capacity was determined by phosphomolybdate assay and the ferric reducing antioxidant power (FRAP) assay was used to determine the reduction potential of the extracts. The spectrophotometric and qualitative analysis of plant extracts demonstrated the presence of alkaloids, terpenoids, carbohydrates, and cardiac glycosides. The occurrence of more than one Rf values for extracts determined by TLC indicated the presence of more than one phytochemical compound. The P. hysterophorus extracts contained strong antioxidant activity. These extracts exhibited strong antimicrobial activity against Staphylococcus epidermis, Salmonela typhi, Neisseria gonococci or gonococci, Citrobacter, and Shigella flexineri. The evaluation of the antimicrobial potential of P. hysterophorus extracts was done by the disc diffusion method. These extracts also showed significant inhibition against HIV-1 RT activity. The anti-HIV-1 RT activity was done using Roche Kit. The P. hysterophorus extracts displayed the presence of many phytochemicals with strong antioxidant, antimicrobial, and anti-HIV-1 RT properties.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Parthenium hysterophorus L. is a noxious weed and a species of flowering plant in the Asteraceae family. It is regarded as the seventh most deadly weed in the world: harmful to both humans and livestock. It is widely known as Congress Grass or Feverfew. Despite its pitfalls, P. hysterophorus bestows medicinal effects. Although prolific in nature and difficult to control, many novel applications of this controversial herb have been discovered as an approach to manage the weed. AIM The current review aims to compile all the ethnobotanical, phytochemistry, biological activities and utilities, clinical studies and toxicity data available on P. hysterophorus and its major chemical constituent parthenin. MATERIALS AND METHODS Extensive literature surveyed Google search, Google scholar, Wiley online library, Elsevier, Springer, Science direct, American Chemical Society, Royal Society of Chemistry and Research Gate. RESULT According to the study, P. hysterophorus is utilized as a traditional medicine throughout Central America and the Caribbean. It can be used to treat skin infections, dermatitis, amoebic dysentery, and as an analgesic in the treatment of muscular rheumatism. The extracts obtained from P. hysterophorus have anti-inflammatory, antioxidant, larvicidal, anti-microbial, insecticidal, hypoglycaemic and anti-cancer activity. CONCLUSION The earlier investigations confirmed that P. hysterophorus has numerous traditional and biological applications. However, the scientific data are limited in clinical and toxicological studies. Therefore, further research is required on clinical and toxicological aspects to understand the complete potential and effects of P. hysterophorus.

Abstract
The noxious plant species Parthenium hysterophorus L. has become a major concern for the conservation of many natural and managed areas. The species is known for its various adverse effects on the invaded ecosystems, particularly in terms of biodiversity loss. Currently, P. hysterophorus is a leading invasive species widespread in the grasslands of productive and diversity rich Indo-Gangetic plains of India and is responsible for various changes in the ecosystem. The present study addresses the changes that P. hysterophorus can bring in the vegetation structure (species richness, species evenness, and species composition) of the grasslands of Indo-Gangetic plain. To broaden our understanding of the invasion success and facilitated expansion, we also focus on the variability of soil nitrogen pool and processes as a consequence of invasion. We report that in the presence of P. hysterophorus, the species diversity, evenness, composition and richness were altered, affecting many native and non-native flora of the ecosystem. The effect was more prominent during the second and third year of the study with more increase in the invasion outcomes. Significant changes in soil nitrogen (N) dynamics, particularly, increased available (N), N-mineralization and microbial biomass N have been found in the invaded plots along with changes in vegetation of the grassland community. Overall, the result suggested that the invasive species, P. hysterophorus, modifies the soil and this modification is correlated with changes in vegetation structure and this situation is likely to further facilitate severe alterations in the ecosystem and could favor encroachment of other non-native species in the area.

Abstract
Being one of the notorious weed P. hysterophorus has invaded almost every part India and is the lead cause of skin allergies and severe dermatitis among farmers and rural population. It is an invasive obnoxious weed capable of surviving extreme environmental conditions and various parts of this plant are reported to cause severe contact allergies in humans due to the presence of high concentrations of toxic sesquiterpene lactones viz. parthenin. It can stimulate numerous cellular and immune responses that may translate into Oxidative stress, allergies, and inflammation. The effect of P. hysterophorus flower extract was evaluated on cell viability, oxidative stress and inflammation in A549 lung cancer cell line by spectrophotometric and reverse transcriptase-polymerase chain reaction methods. Schrodinger software based docking was performed for possible interactions studies. The A549 cells treated with P. hysterophorus flower extract favors increase in cell viability, reactive oxygen species generation. The mRNA expression of proinflammatory cytokines such as IFN-γ, TNF-α, and IL-1β was significantly increased whereas no change in IL-18 expression was observed. Significant increase in protein expression of NF-κB was observed, suggesting the role of NF-κB signalling in allergic responses. The docking studies demonstrated the potential interaction between Parthenin and NF-κB/IL-1β/IL-18 suggesting their activation leading to inflammation. The current study emphasize that P. hysterophorus mediates oxidative stress, and inflammatory process via alterations in expression of proinflammatory cytokines such as IL-1β, IFN-γ through NF-κB activation which was also confirmed in docking studies. Cellular and molecular mechanisms involved in pathogenesis of allergic/chronic inflammation and severe dermatitis need to be further investigated to identify specific binding partners responsible for severe inflammation which can provide some leads in developing effective targets against severe dermatitis and skin allergies.

Abstract
Skin contact or exposure to sensitizers often occurs as a consequence of occupational exposures (e.g. poison ivy in forestry), wearing jewelry (e.g. nickel), or use of cosmetics (e.g. fragrances). However, many of the known skin sensitizers or their chemical variants are also consumed orally through foods or other sources. Since oral exposure to antigenic substances can lead to tolerance, consumption of sensitizers may impact the development and potency of skin sensitization, especially if the sensitizer is consumed early in life, prior to the first skin contact. To address this issue, we have reviewed human clinical and epidemiological literature relevant to this subject and evaluated whether early oral exposures to relevant sensitizers, or their chemical variants, are associated with reduced prevalence of skin sensitization to three main allergic sensitizers - nickel, urushiols of poison ivy, and sesquiterpene lactones of chrysanthemum and other plants.

Abstract
Allergic contact dermatitis following exposure to Parthenium is a chronic disease associated with frequent relapses and significant disturbance in the quality of life. The affected patients have lower circulating levels and decreased expression of IL-10. Hence, measures to increase its level may enhance the therapeutic outcome. The clinical trial was undertaken to evaluate the effect of cholecalciferol supplementation on treatment response and IL-10 level in Parthenium dermatitis patients with vitamin D deficiency. A total of 72 patients were recruited and randomized to receive either cholecalciferol tablet 60,000 IU per week or matching placebo for 8 weeks with standard background treatment. Eczema Area Severity Index (EASI) and Dermatology Life Quality Index (DLQI) were assessed at baseline, 4 weeks, and 8 weeks while IL-10 and serum 25-hydroxyvitamin D levels were measured at baseline and 8 weeks. Levels of 25-hydroxyvitamin D and IL-10 showed a significant rise in both placebo and vitamin D groups following the intervention. The relatively higher increase in IL-10 level observed in the vitamin D group was statistically insignificant compared to placebo group. Significant reduction in EASI, as well as DLQI scores, was noted after 1 and 2 months, but the reduction in these scales was not significantly different between the groups. Cholecalciferol supplementation for 2 months did not reduce the disease severity in clinically diagnosed Parthenium dermatitis patients. However, treatment initiation significantly improved plasma IL-10 levels after 2 months in both placebo and cholecalciferol groups.

Abstract
Parthenium hysterophorus is a weed of global concern with high threshold of tolerance against most of biotic and abiotic stresses. Phytochemical profile and in vitro antioxidant analysis may help in understanding its tolerance to stresses. Root, stem, leaf, phyllary, and receptacle (including disc and ray florets) were chemotyped employing GC tof-MS and assessed for antioxidant activity by DPPH, FRAP, HRSA, and TAC assays. Phytochemicals identified were terpenes, fatty acids, hydrocarbons, phytosterols, and compounds of miscellaneous chemical nature. Organ-specific maximum concentration of metabolite was β-vatirenene (root), hexadecanoic acid methylester (stem), aristolene epoxide (leaf), hexadecanoic acid methylester (phyllary), and hexadecanoic acid methylester (receptacle). Identified metabolites could be associated with stress tolerance mechanisms, basic metabolism, and allelopathy, etc. Root extracts showed highest antioxidant potential followed by receptacle. It can be concluded that diverse and unique phytochemical profile and great antioxidant potential make P. hysterophorus stress-tolerant, hence a weed of global habitat.

Abstract
INTRODUCTION Occupational contact dermatitis, accounting for 95% of cases of occupational dermatoses, is the most common occupational skin disease. AIM To find out the various allergens in different occupational and environmental settings causing contact allergy, from our patients presented with contact dermatitis. MATERIALS AND METHODS It was a retrospective study from the data in hospital outpatient register over one year period, which includes patients with age ranging from 11 years to 73 years. Patch test was done with total of 24 allergens from Indian standard battery and Indian standard series and with materials suspected to cause contact allergy. Result was expressed in terms of percentage. RESULTS Contact dermatitis constitutes about 0.75% of total dermatological cases in our Dermatology Outpatient Department. A total of 358 contact dermatitis were included in this study with M:F ratio 2.25:1 and majority of the cases in the age group of 26-55 years. Out of 358 cases, 157 cases were positive to at least one allergen. Building construction workers constitute about 35.75% (128 cases) of total contact dermatitis cases, among which potassium dichromate (39 out of 57) is the most common allergen, followed by nickel (31) and cobalt (28). In other occupations, contact allergy to parthenium, hair dye, foot wear, paint, kum-kum, turmeric, detergents and cosmetics were also present in significant number and none was positive for vegetables, dettol, kerosene and native medication. CONCLUSION This study gives an idea about the common occupation and population who are prone to develop contact dermatitis in our environmental setting and also about the most common sensitizers involved in various occupation and environment.

Abstract
Feverfew (Parthenium hysterophorus), an invasive weed from the Asteraceae family, has been reported as allergen source. Despite its relevance, knowledge of allergens is restricted to a partial sequence of a hydroxyproline-rich glycoprotein. We aimed to obtain the entire sequence for recombinant production and characterize feverfew pollen using proteomics and immunological assays. Par h 1, a defensin-proline fusion allergen was obtained by cDNA cloning and recombinantly produced in E. coli. Using two complementary proteomic strategies, a total of 258 proteins were identified in feverfew pollen among those 47 proteins belonging to allergenic families. Feverfew sensitized patients’ sera from India revealed IgE reactivity with a pectate lyase, PR-1 protein and thioredoxin in immonoblot. In ELISA, recombinant Par h 1 was recognized by 60 and 40% of Austrian and Indian sera, respectively. Inhibition assays demonstrated the presence of IgE cross-reactive Par h 1, pectate lyase, lipid-transfer protein, profilin and polcalcin in feverfew pollen. This study reveals significant data on the allergenic composition of feverfew pollen and makes recombinant Par h 1 available for cross-reactivity studies. Feverfew might become a global player in weed pollen allergy and inclusion of standardized extracts in routine allergy diagnosis is suggested in exposed populations.
