(2) Research Areas

 

·      Allergic Bronchopulmonary Aspergillosis: An epidemiological study on ABPA has been done for the first time in India and the prevalence of ABPA was 16% in asthmatic patients (Asian Pacific Journal of Allergy and Immunology-2000; Clin Pul Med-2004). For the first time, a clinico-serological evaluation of ABPA has been done staging ABPA as mild, moderate and severe form of ABPA. (Journal of Asthma-2002, Chest-2003). The ABPA patients were categorized as ABPA-S, ABPA-CB and ABPA-CB-ORF for the first time. This study was awarded for David A and Julie A Stevens Scholar award in 2006 at Greece. ABPA with Aspergilloma mimicking pulmonary tuberculosis has been seen and many cases of ABPA was evaluated, 30% of ABPA were misdiagnosed as tuberculosis and given treatment (Ind J Tub; 47:103-105, Ind J Tub 2000, Ind J Allergy Asthma Immunol 2003, Indian J. of Allergy, Asthma and Immunology, 2010, Annals of Allergy, Asthma & Immunology 2011). A clinical, serological and radiological characteristic of patterns of ABPA was evaluated (Annals of Allergy, Asthma & Immunology 2011). The role of Itraconazole in ABPA has also been examined (Saudi Medical Journal-2003). Subsequently, the study of ABPA has been reviewed extensively and published in different journals.

 

·      Food Allergy in Bronchial Asthma: Role of food allergy in bronchial asthma has been studied in detail including epidemiology, type of common food products causing allergy and clinical and serological aspects in the diagnosis of food allergy in bronchial asthma (Clin. Pulm Med-2005). Black gram allergy in patients of asthma and rhinitis; Prevalence of food allergy in respiratory diseases (Allergy-2005); Relevance of IgE estimation in allergic bronchial asthma with special reference to food allergy (Asia Pac All Immunol 2006); Sensitization of blackgram allergy in patients of asthma and rhinitis. Clinical evaluation and characterization of allergens (Allergy 2006); Rice allergy in rhinitis and asthma (Immunology 2007) has been studied extensively. Prevalence of food allergy by identification of IgE mediated food allergy and allergens in older children’s and adults with asthma and rhinitis was evaluated and found out to be 4% (India J Chest Dis Allied Sc 2010).

 

·      Bronchial Asthma: Specific detailed studies undertaken covered topics such as Prevalence of asthma in school girls; Evaluation of market spacer in bronchial asthma: Study on different drugs (Ipratropium Bromide, Tiopropium) used in bronchial asthma; Role of inhaled Frusemide in asthma; Pulmonary function test of parents of asthmatic children; Exhaled carbon monoxide level as marker of clinical severity and control of asthma; Pulmonary rehabilitation in asthma and COPD; Inhaled magnesium sulphate in severe asthma; Time of recovery of acute exacerbation in asthma, IgE level in asthmatic patients and their families has been studies. Affect of Indoor Air Pollutants and Bronchial Asthma in Children has been evaluated extensively.

 

·      Rhinitis: Airway obstruction in rhinitis is an important area studied in detail besides other aspects of rhinitis. Different drugs (Budesonide, Beclomethasone) used have been studied for their efficacies. Pulmonary function test in patients of Rhinitis and Prevalence of Allergic Rhinitis in Children has been evaluated. Indore Air pollutant level such as RSPM, SO2, NO2, and rhinitis has been studied in children’s.

 

·      Allergy/Allergy testing: A study of skin sensitivity to various allergens by Intradermal test in patients (341) with respiratory allergy, bronchial asthma and allergenic rhinitis in India has been studied and published (Intern med J Thai 2003). Three hundred and forty one patients have undergone allergy testing with 20,119 Intradermal tests done. Identification of cross-reactive patients amongst different curvularia species (Int Arch Allerr & Immu 2002), allergic cross-reactivity of curvularia lunata with other airborne fungal species (Allergy 2002) have been studies.

 

·      Indoor Air Pollution and respiratory allergy: Role of indoor air pollution on respiratory system of children in different parts of Delhi has been studies. The correlation between clinical symptoms, Spirometry, passive smoking and Indoor air pollutants like NO2, SO2 and SPM have been evaluated in homes of different parts of Delhi. Indoor air pollution and history of asthma, rhinitis, URI have been extensively studies. (Archives of Environmental & Occupational Health 2007: 62 (2); 75-80, Asia Pacific Journal of Public Health. 2008 Vol (20) No.1, 36‑48). Impact of domestic air pollution from cooking fuel on respiratory allergy in children in India has been studied (Asian Pacific Journal of Allergy and Applied Immunology (2008) 26: 213-222). Other studies conducted were – Effect pf air pollution on respiratory systems of auto-rickshaw drivers in Delhi; Bronchial asthma in petrol pump workers(Ind J Occ and Env Medicine 2000; 4(4): 168- 171, Indian Journal of Occupational and Environmental Medicine 2003; 7(3): 13-16).

 

·      Smoking Cessation: Tobacco consumption among college students of University of Delhi has been done and total 25% students use tobacco in one of the form (Ind. J. of Prev. Social Medicine – 2010). The Role of Pharmacotherapy and counseling in Tobacco Cessation was evaluated and the quit rate at one year as found to be 26% (Lung India 2010, Ind. J. Chest Allied Sci-2007). Tobacco Cessation in India was review (Ind. J. Chest Dis. Allied Sci.-2005). Effect of smoking on atopic predisposition and sensitization to allergens were studies (Indian J. Chest Allied Sci.-2008). A comparative study was done between bidi and cigarette smokers and Breath CO level was found to be significantly more in bidi smokers compared to cigarette smokers. (Ind. J. Chest Dis All. Sci.-2010). Breath CO level in passive smokers mainly the worker in hotel restaurants, bar were studies and found to be significantly high compared to non smokers (Ind. J. Chest Dis. Allied Sci. 2011). Rhinitis was found to be more in bidi smokers comparison to cigarette smokers (Ind. J. Allergy, Asthma, Immunol 2011). Contributed to develop Tobacco Dependence guideline for national tobacco control programe, Govt. of India (Tobacco Dependence Treatment Guideline Govt. of India-2011). The smoking Cessation program and other preventing strategies for COPD was evaluation. (JAPI-2012).

 Achievements

 

1.  For the first time in India, systematic comprehensive studies on the etiologic significance of pollen, insects, fungi, algae and animal dander, etc., in respiratory allergic disorders have been undertaken which involved the development of various modern in vitro techniques to study their allergenic and antigenic properties. These techniques include Radio-allergosorbent test (RAST), Rocket immunoelectrophoresis, Crossed immunoelectrophoresis (CIE), Crossed-line immunoelectrophoresis (CLIE), Sodium dodecyl sulphate -Polyacrylamide gel electrophoresis (SDS-PAGE), Thin layer isoelectric-focussing (TLIEF), etc. In addition, the immunochemical quantitation of airborne insect-derived allergen particles has been carried out for the first time in our country.

 

 

2. Development of an easy method of inhalation provocation test to detect the cause of allergic asthma which has been referred to, in standard text book of Respiratory Medicine by Crofton.

 

3. Establishment of monoclonal antibody staining techniques for the study of immunology of tuberculosis and leprosy.

 

4. Some of the studies have helped in understanding the alterations of immune system (i) in diseases like tuberculosis, leprosy and breast cancer and (ii) on treatment with drugs.

 

5. Study on phylogeny of immune response revealed that as one goes higher in the evolutionary tree, the classical complement pathway becomes more active as compared to alternative complement pathway.

6. Prevalence of food allergy in Bronchial asthma has been studied. The percentage of Food-related symptoms is common among respiratory allergy patients. Self-reports prevalence of food allergy was 69% could be confirmed in 4.4%, resulting in an overall estimated prevalence of 1.1% ([0.7101.75] at 95% Cl) in respiratory allergy patients. The common offending foods are rice, citrus fruits, blackgram and banana. Indoor air pollution and respiratory allergy.

7. Effect of Indoor air pollution on respiratory allergy has been studied extinguisley. Impact of air pollution like NO2, SO and RSPM has been studied.

 

8. An epidemiological study on ABPA has been done for the first time in India and the prevalence of ABPA was 16% in asthmatic patients.

 

9. For the first time, a clinico-serological evaluation of ABPA has been done staging ABPA as mild, moderate and severe form of ABPA. The ABPA patients were categorized as ABPA-S, ABPA-CB and ABPA-CB-ORF for the first time. This study was awarded for David A and Julie A Stevens Scholar award in 2006 at Greece.

 

10.Tobacco consumption among college students of University of Delhi has been done and total 25% students use tobacco in one of the form and the Role of Pharmacotherapy and counseling in Tobacco Cessation was evaluated and the quit rate at one year as found to be 26%.

 

11.   A comparative study was done between bidi and cigarette smokers. The Breath CO level was found to be significantly more in bidi smokers compared to cigarette smokers. The Breath CO level in passive smokers mainly the worker in hotel restaurants, bar were studies and found to be significantly high compared to non smokers.

 

Transfer of Technology

 

Identification of local allergens lead to proper diagnosis and treatment of the patients with respiratory allergy. The results of immunotherapy with specific local allergens were encouraging. This created an exceedingly heavy demand on the Department for supply of these allergens from all over the country. Until 1969, the Department tried to cope with the ever increasing demand but the patients had to wait for several months for investigations and treatment. The Department at that time transferred the technology of allergen preparation to the CSIR, Institute of Genomics & Integrative Biology, a Govt. of India Undertaking to make them available on commercial scale for the use on patients.

 

Teaching/Training Programmes

 

Workshops on allergy, allergens and immune response

 

In 1975, the Department started conducting biannual Workshops on Allergy, Allergens and Immunotherapy in order to impart training, in clinical and laboratory aspects of diagnosis and management of allergic respiratory diseases to medical practitioners and faculty members of hospitals/research institutions working in various parts of India. From 1981 onwards, the Institute has been conducting these workshops in collaboration with the Institute of Genomics & Integrative Biology (CSIR). Faculty members and scientists from the VP Chest Institute, the Institute of Genomics & Integrative Biology (IGIB) and other medical institutions from Delhi and other parts of India participate in the teaching programme. About 25-50 medical postgraduates are trained annually in these workshops. The latest workshop in this series on "Respiratory Allergy: Diagnosis and Management" which was the 37th workshop held on April 2-6, 2012.

 

Patient’s Care

 

The Department has been the pioneer centre for research and teaching in the identification of local allergens and management of respiratory allergic disorders by administering immunotherapy. The skin test facility provided by the Department for a large number of patients has been helpful in proper diagnosis and efficient management of respiratory allergy diseases. In selected patient the Immunotherapy is given for therapeutic use. The department involved in the following activities:

Research

 

1. Studies on pollen allergy in Delhi metropolitan area

 

Systematic and comprehensive studies on the identification of clinically important pollen aeroallergens were undertaken. These studies involved, (i) Field surveys of Delhi and adjoining areas. (ii) Aerobiological surveys to identify and enumerate common airborne pollen types to study their seasonal prevalence. (iii) Collection and processing of common pollen types. (iv) Preparation and storage of pollen extracts, and (v) Clinico- immunologic studies to evaluate their allergenic significance. A large number of pollen types were identified 'and quantified in the air and their seasonal patterns were recorded. More than 150 different pollen extracts were prepared and were evaluated for their allergenic significance in patients with allergic respiratory disorders. About 50 of them were. found to be clinically significant. Besides these common anemophillous pollen allergens, allergy to pollen of an entomophillous plant (papaya tree) was also reported.

 

2. Studies on the allergenic significance of plants parts Parthenium and its relationship to pollen allergens Allergenic -potential of pollen and various parts of Parthenium hysterophorous was also studied: Pollen extract was found to be allergenic in 28% patients followed by flower (8%) and leaf extracts (6%) in that order. These studies suggested close relationship among pollen, leaf and flower extracts.

3. Atopic relationship amongst some species of chenopodiaceae and amarant- haceae 

Antigens from pollen of the four species of chenopodiaceae (viz. Chenopodium album, C. murale, C. ambrosioides and a tetraploid of C. album) and two species of Amaranthaceae (viz. Amaranthus spinosus and A. hybridus) were skin tested on about 100 patients of nasobronchial allergy. The results indicated that positivity proneness of the patients varied from species to species; probably due to species in chenopodiaceae specific allergenic factors in this family.

 

4. Studies on allergenic fungi of Delhi metropolitan area A comprehensive, systematic study of aerial fungal spores in Delhi area was undertaken. In early sixties the fungal spores were enumerated using gravimetric methods by simultaneous exposure of slides and petri-plates. Two peak periods of fungal spore concentration were reported, one from September to November and the other from February to April. A comparison of results of the two gravinetric techniques with those obtained with a volumetric sampler was made in late 1980's. Of the 150 fungal types encountered in Delhi air, 20 were show:1 to be allergenic and aetiologically related to respiratory allergic disorders. Several new fungal allergens including 12 species of Aspergillus have also been identified.
 

5. Identification of new fungal allergens 

 

Volumetric aeromycological survey of Delhi was undertaken to identify and quantify yet unknown airborne allergenic fungi of Delhi area. With a view to evaluating their significance as inhalant allergens, intradermal tests with a number of new fungal extracts were performed on the patients with respiratory diseases. Results showed that Penicillium nigricans, P. chrysogenum, P. funiculosam, Aspergillus clavatus, Fusarium chamydosporium, Nigrospora sp., Syncephalastrum sp., Gliocladium sp., and Trichoderma viridae were allergenically significant. Inclusion of these yet unknown fungal allergens in the skin test kit will increase the scope of identification of causative allergens in the patients of allergic respiratory disorders.

 

6. Presence of shared as well as unique allergenic and antigenic components in different fungal species Systematic studies were undertaken on the presence of shared or specific allergens or antigenic components among various genera, species and varieties of airborne fungi. .The results revealed that the allergenic and antigenic components among different fungal genera were largely specific and only a few of them were cross-reacting. Among various species of Aspergillus, a number of both shared as well as species specific components were observed. However, most of the allergenic and antigenic components among different varieties of P. funiculosum were found to be cross-reacting and only a few of them were variety specific.
 

7. Studies on insects Aetiologic significance of about 35 insects, prevalent in Delhi atmosphere was evaluated and all of them were found to be important inhalant allergens. Elevated levels of insect allergen specific IgE antibodies in the sera of respiratory allergy patients by radioimmunoassay were found.
 

8. lmmunochemical quantification of airborne insects and other allergens The etiologic significance of insects as producers of inhalant allergens causing type I respiratory allergic diseases was demonstrated by immunochemical quantification of airborne insect allergens for the first time in India, The insects studied were butterfly, moth, mosquito and housefly. These results have established conclusively that insects play an important role in type I hypersensitivity disorders of respiratory system.

 

On immunochemical quantification, seasonal varieties were noted in the amounts of airborne horse and dog dander allergens. Horse dander allergen varied from 0-16.5 ug/m3 of air, its peak periods being January to April and September to October. Airborne dog dander allergen ranged from 0-4.7 ug/m3 of air and was maximum during the months of January to March and September to December.

 

9. Demonstration of shared as well as unique allergenic and antigenic components in different insects genera and species and male/female cockroaches Clinicoimmunologic and immunochemical analysis of the allergen extracts of male and female cockroaches (Periplaneta americana), different genera of cockroaches (P. americana and Blatella germanica) and mosquitoes (Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti) revealed the presence of shared as well as specific allergenic and antigenic components in different sexes and genera of insects, These observations will have significant bearing on the immunotherapy of patients with respiratory allergy.

10. Etiologic significance of various dusts in respiratory allergy Of the four dusts investigated, house dust and rice dust were found to be important as inhalant allergens, while the other two (cotton and paper dusts) were almost of no allergenic significance. All the dust related arthropods (housefly, rice weevil, male and female cockroaches and house dust mite) were also found to be important sources of inhalant allergens. However, these arthropods were not found to contribute significantly to the allergenicity of house dust and rice dust allergens.

 

11.Purification and characterization of significant allergenic components of clinically important inhalant allergens Allergen extracts used for diagnosis and immunotherapy of patients with respiratory allergic disorders are crude, complex mixtures, each comprising a number of biochemical components of different shapes, sizes and properties. While some of them may be allergenic others are non-allergenic. A few of the allergenic components may be major while some others are minor contributors in the allergic activity of the crude extract. For efficient diagnosis and efficacious immunotherapy in patients, it is important that extracts of appropriate biological activity are used. However, techniques/ immunological reagents are not available for the quality control of various commercially available allergen extracts. The Department has been working on the purification, isolation and characterization of major allergenic components of different groups of allergens. Partial purification of the whole body extract of cockroach (male and female) suggested the presence of shared low molecular weight significant allergens and cockroach (male) specific high molecular weight minor allergens. In housefly, Fr. III (~66 ,KD) has been identified as one of the significant allergens.
 

12. Study on the time course of retention of allergenic activity of some important allergen extracts Usually an allergen extract, when stored at 4oC in aqueous form, is considered to retain its allergenic activity for a period of one year. However, loss of biological activity was observed in some extract within 9 months, while some other extracts showed retention of activity for 15 or more months, even when stored at room temperature. While extracts with reduced allergenic activity should not be used for diagnosis and therapy of patients, discarding the batches of latter extracts after one year storage, while they are still biologically active, will lead to financial loss. Thus, there is an urgent need of studying the shelf life of other clinically important extracts.
 

13. Comparison of biological activity in some clinically important, allergen extracts supplied by different manufacturers The diagnostic efficiency and therapeutic efficacy of various allergen extracts used for skin tests and immunotherapy in patients with IgE mediated bronchial asthma and/or allergic rhinitis depend on the biological activity in the allergens extracts used. No quality control methods/reagents are available for standardization of allergen extracts in India. For this purpose, the present study has been undertaken to compare the biological activity in commercially available allergen extracts prepared by different manufacturers in India. Biological activity varied from allergen to allergen. The results emphasize the need for developing immunologic reagents and procedures for quality control of clinically important allergen extracts in our country.
 

14. New methods for enumeration of airborne (i) total (viable + non-viable), (ii) only viable, (iii) immuno-cheniically quantified fungal allergens A new technique to quantify (i) total (viable + non viable) and (ii) (only viable) fungal species using the Burkard's Air Sampler was developed. Subsequently a new approach for simultaneous counting of air borne (i) total, (ii) only viable fungal spores and (iii) Immuno-chemically quantified fungal aeroallergens using membrane filtration technique was developed. The amount of allergen quantitated had a good correlation with the spore colony counts. House dust mites and their significance as aeroallergens. Mite fauna of house dust samples was studied. Various species of house dust mites (HDM) were identified and counted in the house dust samples of respiratory allergy patients in Delhi area. The results established that HDM is an important inhalant allergen in India.
 

15.Clinico-immunologic study on comparative evaluation of the sensitivity and specificity of common methods of diagnostic tests used in patients suffering with IgE mediated type I in allergic respiratory diseases The sensitivity and specificity of various diagnostic methods to identify the offending allergens in patients of respiratory allergy was compared employing skin tests, bronchial provocation tests (BPT), conjunctival tests and radio- allergosorbent tests (RAST). The results showed that the skin tests performed and graded as per the method and criteria developed in the Department give reliable information and the technique is very sensitive and specific. Results of skin tests showed a good co-relation with the BPT and RAST.
 

16. Development of a rapid method for preparation of allergen extracts A rapid method of preparation of allergen extracts was developed in which a mixture of chloroform and methanol was found to be a better defatting agent than conventionally used diethyl ether, and two hours period of extraction in the buffered saline was sufficient for optimal allergen recovery.
 

17. Studies on the causative allergens in patientsSeveral studies were undertaken to evaluate the etiologic significance of offending allergens in patients of bronchial asthma and allergic rhinitis using a number of allergens of different groups i.e. pollen, fungal, dust, animal dander and insect extracts. Results showed that all these groups played an important role in the etiology of allergic disorders in patients. The causative allergens varied from patient to patient and in different permutation and combination to various allergens of different groups.
 

18. Investigation on the role of immunotherapy in patients suffering with nasobronchial allergy Several studies on the therapeutic efficacy of immunotherapy in patients with nasobronchial allergy were undertaken. The best results were obtained in the patients suffering with seasonal nasobronchial allergy. It was observed that immunotherapy administered in properly selected patients gives encouraging results.

 

19. Studies on bronchial tolerance to histamine, methacholine chloride and specific antigen inhalation Increase in bronchial tolerance to histamine, methacholine chloride and specific allergens inhalation challenge was observed after treatment with Tylophora indica leaves, its alcoholic extract or its alkaloids. Similar therapeutic response was observed in patients after ingestion of whole plant powder of Solanum xaenthocarpum whole plant.
 

20. Effect of prior medication on intradermal test response in patients with respiratory allergies Our studies revealed that certain drugs used for symptomatic treatment of asthma, such as salbutamol, theophyline, adrenaline, etc., were found not to interfere with the results of intradermal tests in patients with type I respiratory allergy. Thus, skin testing of patients need not be postponed due to their inability to discontinue these drugs. However, use of long acting antihistamine-Astemizole resulted in abrogation of interdermal test response to allergens up to four weeks. Thus, it is recommended that prior to performance of skin tests such anti- histamines should be discontinued for a suitable period.
 

21. Studies on the role of animal danders in the etiology of respiratory allergic disorders Evaluation of seven animal danders as inhalant allergens was undertaken and relative allergenic significance was studied. The presence of shared and specific allergenic components in different animal dander was found.

22. Influenza virus infection and levels of total allergen specific and virus specific IgE in patients with respiratory allergic disorders The role of influenza virus in the etiology of type I respiratory allergic disorders was studied. The results suggested that respiratory viruses may precipitate symptoms of asthma either by inducing an increase in the total, or allergen-specific IgE (non-virus) and/or virus-specific IgE antibodies.
 

23. Role of food allergens in the etiology of nasobronchial allergy The role of 25 food allergen in etiology of respiratory allergy was studied. A sizable percentage of patients showed marked skin positivity to one or more food allergens suggesting their etiologic significance in the causation of nasobronchial allergy. Our results suggested that a markedly positive skin reaction to food allergens should not be ignored which may be confirmed by performing bronchial provocation test and/or RAST.
 

24. Heterogeneity of IgE mediated immune response to insects in patients with naso-bronchial allergic disorders A total number of 346 patients of bronchial asthma and/or allergic rhinitis were tested with 17 insect extracts. Sera of 200 of these patients were studied in various insect RASTs for the presence of allergen-specific IgE antibodies. The patients showed skin reactivity and RAST positivity to more than one of the 17 insect extract in various permutations and combinations. These results crossed- RAST -inhibition and absorption studies showed heterogeneity of immune response of patients to these insect allergens.

 

 

25. Comparative efficacy of 2 RHZE/4RH (4D) regime Vs 2 RHZ /4 RH (3D) regimen in Category I sputum positive pulmonary tuberculosis(R: Rifampicin; H: Isoniazid; Z: Pyrazinamide; E: Ethambutol).

29. Studies involving T cell homeostasis in tuberculosis patients at the start and following three months of chemotherapy revealed that there was a drastic alteration in T cell subsets in these patients which reverted to normal after three months of successful chemotherapy.

 

30. The T4/T8 homeostasis was also altered in patients with various stages of breast carcinoma and benign breast diseases.

 

31. Lymphocytes with HLA-DR II and IL-2 receptor markers were also reduced in patients with breast carcinoma. The blood levels of IL-2 of carcinoma pa1ients were comparable to that of normal controls although their blood levels of sIL-2R were increased.

 

32. The nutritional deficiency in leprosy patients was found to be poverty related and not disease related. The serum Zn, vitamin A and E levels were associated with disease.

 

33. Dapsone and Clofazimine, the important constituents of multi-drug therapy (MDT) were found to alter the early components of the complement pathway, in- vitro, only at a very high concentration.

 

34. Clofazimine alone enhanced O2 production of rat resident peritoneal macrophages in a dose-dependent manner. The drug lost. this property after exposure to light. Detailed physico-chemical properties (i.e. UV, IR, NMR and mass spectra) of light reacted Clofazimine were also studied.

 

35. Rats treated with MDT showed altered T cell homeostasis, while there was no effect on CH-50, C3, total T cells (W3/13), B cells (OX-4) or immunoglobulin levels.

 

36. The haemagglutinins isolated from Indian fresh water catfish were shown to be specific towards L-galactopyranose. This activity was radioresistant suggesting that the haemagglutinin could be a lectin.

 

37. The purified haemagglutinin from Indian fresh water catfish had native molecules of molecular weights of 187 KD and 55 KD. The ultrastructure of immune apparatus of this catfish was also studied.

 

38. Food Allergy in bronchial asthma.

 

The percentage of Food-related symptoms is common among respiratory allergy patients. Self-reports prevalence of food allergy was 69% could be confirmed in 4.4%, resulting in an overall estimated prevalence of 1.1% ([0.7101.75] at 95% Cl) in respiratory allergy patients. The common offending foods are rice, citrus fruits, blackgram and banana.

 

39. Isolation and characterization of a 28 kDa major allergen from blackgram (Phaseolus mungo)

 

Study was aimed to isolate and characterize a major allergenic protein from blackgram (Phaseolus mungo). Respiratory allergy patients with history of blackgram allergy were skin prick tested (SPT) and sera were collected from SPT positive patients. The purified protein separated at 28 kDa on 12% gel and showed IgE binding with 81% of blackgram hypersensitive patients’ sera on immunoblot indicating it to be a major allergen.

48.Trace elements in indoor airborne particulate matter of Delhi and its effects on respiratory Allergy among children.

 

The present study was undertaken in Shahdara and Shahzada Bagh industrial locations of Delhi with the primary objective to determine the trace elements in indoor suspended particulate matter (SPM) and its effects on respiratory allergy in children. 3.8% children were exposed to environmental tobacco smoke (ETS). Diagnosis of asthma, rhinitis and upper respiratory tract infection (URTI) was made in 11.8%, 38.9% and 36.2% respectively.

 

 

49.Compositional study of domestic airborne particulate Matter in industrial locations of Delhi and its Relationship with asthma in children.

 

The present study was undertaken in Shahdara and Shahzada Bagh industrial areas of Delhi with the primary objective to determine the mineralogy and chemical composition of indoor suspended particulate matter (SPM) and its association with asthma in children. 11.8% children were diagnosed to have asthma of which 14.2% were in Shahdara and 9.6% in Shahzada Bagh. The level of indoor SPMwas high in the houses of Shahdara and Shahzada Bagh industrial areas of Delhi where children had asthma. Mineral groups such as quartz, carbonates (calcite and dolomite), mica (illite and muscovite), feldspar, talc-chlorite (talc and chlorite) were identified in the indoor SPM. High amount of quartz and mica minerals were associated with asthma in children. Major elements including Si, Al, Fe, Mg, Ca, Na, K, Mn and trace elements such as Cr, Co, Ni, Pb, Cu, Zn, Mo, Cd were also determined in the indoor SPM. The mean concentration level of Si, Cr, Ni, Pb, Zn and Cu was statistically significantly high in the houses where children had asthma.

 

 

50.Obstructive Sleep Apnea in Asthma and COPD Patients and its Relation to Atopy.

 

Patients with asthma and COPD were evaluated for OSA symptoms by Epworth Sleepiness Scale (ESS) and Berlin Questionnaire (BQ). Patients having high risk for OSA by ESS and BQ underwent home based sleep study. Skin prick test (SPT) against common allergens was done to diagnose atopy. ESS was positive in 12% of COPD patients and BQ was positive in 18% of COPD patients. In the BQ positive asthma patients SPT was positive in 66%, whereas in COPD it was positive in 71%. Out of BQ positive patients, underwent home sleep study and were found to have OSA. The Patients from home sleep study group underwent SPT, 69% were found to be atopic.

 

51.Relationship of Atopy and Exhaled Nitric Oxide in Patients of Allergic Rhinitis.

 

The aim of the study to investigate the relationship, between atopy and FeNO in patients of allergic rhinitis. FeNO levels were assessed in patients of both the sub-groups, the average value being 20.65 ± 13.10 ppb. The levels in atopic patients were 25.13 ± 12.79 ppb. On compared to levels in non-atopic patients 14.5 ± 11.14 ppb, the FeNO levels in atopic patients were significantly higher with statistical correlation (p = .009). However, no correlation was found between the number of SPT positives and levels of FeNO.

 

52.Breath carbon monoxide level of non-smokers exposed to environmental tobacco smoke.

 

     The study was conducted with the help of a pre-designed questionnaire. The breath CO level was significantly higher in ETS exposed subjects who worked for more than nine hours a day in bars, restaurants and hotels (p = 0.018).
