ABSTRACT
Observations for over eighteen months with the establishment of an Allergy Clinic at the Port-of-Spain General Hospital are being presented. Skin testing for immediate Type I hypersensitivity by the Gell and Coombs classification was done on all patients with a history of allergy. The skin testing results showed that 63 percent of the patients were positive to Dermatophagoides pteronys-sinus; 55 percent positive to D. fariniae; 48 percent to house dust; 31 percent to a mixture of 4 moulds and 32 percent to a mixture of feathers. Therefore house dust mites and house dust were the major offending allergens. This confirms the observation in the temperate region that asthma is related to allergy and to house dust mites. During the course of this clinic, it was observed that in the majority of the patients with allergies, illnesses seemed to occur at the time of the year coinciding with that of the highest humidity. Consequently, a retrospective study of asthma with hospital data on admission was reviewed over a five-year period, 1975-1979. The mean monthly admission rate was 66 (range 46 to 98) with a rate of 57 (range 46 to 69) from January to September and 90 (range 86 to 98) from October to December. This seems to correlate with humidity which is low January to May (mean 79.4 percent) and high in July to December (mean 85.3 percent). The lag between the rise in humidity and the rise in admissions in October could suggest that the relationship is not a direct cause-effect one. The radioimmunoassay method was used for quatitating the serum IgE in a selected group of patients. Mean for the first 26 patients was 485 iu/ml and in only 7 of the first 26 patients done for IgE was less than 300 iu/ml the suggested upper limit. These are high values compared with non-allergic Swedish children whose mean is 66 iu/ml. and healthy Ethiopian children free of parasites whose mean was 325 iu/ml using a similar technique (AU)
