“…Indeed, in their comparative study, these authors too recorded a higher prevalence in the exposed individuals with a more considerable difference for breathing discomfort. Our results are also in accordance with those of Laraqui and his collaborators in Morocco who recorded a rate of 13.4% for dyspnoea [ 21 ].…”

“…Our study showed that there is no difference between exposed and unexposed workers concerning the prevalence of respiratory symptoms. This result is not in accordance with the one obtained by Laraqui and his collaborators who got a prevalence ratio of 2.46 (45.1% in the exposed individuals against 16.3% in the unexposed individuals) [ 21 ]. When we evaluated the prevalence of symptoms in this cohort, comparing individuals directly exposed to those indirectly exposed to cotton dust, there was no difference between the exposed group and the unexposed ( p > 0.05), but when we explored in detail the respiratory symptoms, we noted increased cough, sputum production, chest tightness, and dyspnea, with 10 (1.53%) reporting symptoms consistent with asthma and 22 (3.36%) reporting symptoms consistent with chronic bronchitis.…”

The textile industry sector occupies a prominent place in the economy of Benin. It exposes workers to several occupational risks, including exposure to cotton dust. To assess the effect of exposure to cotton dust on the health of workers, this study was initiated and conducted in a Beninese cotton industry company. The objective of the study was to evaluate the respiratory disorders among the textile workers exposed to cotton dust and the cross-sectional study involved 656 subjects exposed to cotton dust and 113 non-exposed subjects. The methods used are mainly based on a survey using a questionnaire of organic dust designed by the International Commission of Occupational Health (ICOH); and on the measures of lung function parameters (FEV1 and FVC). The main results of the different analyzes revealed that subjects exposed to cotton dust have more respiratory symptoms than unexposed subjects (36.9% vs. 21.2%). The prevalence of chronic cough, expectorations, dyspnoea, asthma and chronic bronchitis are 16.8%, 9.8%, 17.3%, 2.6%, and 5.9% respectively among the exposed versus 2.6%, 0.8%, 16.8%, 0% and 0.8% among the unexposed subjects. The prevalence of byssinosis is 44.01%.The prevalence of symptoms is dependent on the sector of activity and the age of the subject. These results should encourage medical interventions and technical prevention especially since the textile industry occupies an important place in the Benin’s economy.

“…The early removal of the worker from the suspected exposure has important prognostic implications. Several studies have demonstrated that asthma symptoms linked to a workplace exposure may persist years after removal from the exposure [45]. These studies have also shown that the early diagnosis of occupational asthma and the early removal from a suspected exposure are important in regaining lung function and controlling symptoms [46].…”

“…The reduction of the exposure level could be a successful and a sufficient solution for workers without a high bronchial hyper-responsiveness to maintain them at an arranged work station. Even in big companies, rehabilitation is very often difficult because alternative employment is not always available as it is already held by other sick or aged employees [44,45].…”

Nowadays, occupational asthma is the most common form of occupational lung disease in the world. In some countries the textile industry remains an important source of potential agents causing occupational asthma. In the textile industry several agents such as cotton dust and dyes may cause occupational asthma. In this review, we discuss the epidemiology, pathogenesis/mechanisms, clinical presentations, management and prevention specific to occupational asthma in the textile industry.Work-related asthma risk is considerable. Current understanding of the mechanisms by which many textile agents cause occupational asthma is limited, especially for low molecular-weight sensitizers and irritants. The diagnosis is generally established on the basis of a suggestive history of a temporal association between exposure and the onset of symptoms and objective evidence that these symptoms are related to airflow limitation. Early diagnosis, elimination or reduction of exposure to the offending agent and early use of convenient therapy according to disease severity may play an important role in the prevention of long-term persistence of asthma. Its prevention in the textile industry should be both technical and medical. It depends on the difficulties to reduce dust level, the limits in arranging work station or in occupational rehabilitation. These difficulties are increased in small textile industry companies. Persistent occupational asthma in this sector is often associated with substantial disability and consequent impacts on income and quality of life. Prevention of new cases is the best approach to reduce the burden of asthma attributable to occupational exposures. This review also outlines different patents on the diagnosis and treatment of asthma.

We aimed to identify the contemporary prevalence of byssinosis through a systematic review. We used Medline, Web of Science, Embase, and Global Health databases to identify studies published in any language between 2000 and 2019, reporting primary data on byssinosis among adults. We used the Joanna Briggs Institute checklist to estimate the risk of bias in studies and undertook a qualitative, narrative data analysis. The review considered the prevalence of byssinosis, chest tightness, and airflow obstruction in textile workers in low- and middle-income countries (LMICs). We found 26 relevant studies that included 6930 workers across 12 countries. Most of the studies (n = 19) were from Asia, and 7 from African countries. Twenty-five studies were cross-sectional surveys while 1 was a cohort study. The prevalence of byssinosis was reported by 18 studies, and ranged from 8% to 38%, without any clear associations, at the group level, between the prevalence of byssinosis and durations of workers’ exposures. Prevalence of chest tightness ranged between 4% and 58% and that of airflow obstruction between 10% and 30%. We found a strong correlation ( r = 0.72) between prevalence of byssinosis and cotton dust levels. Our findings indicate that byssinosis remains a significant, contemporary problem in some parts of the textile sector in LMICs.
