“…In this study, majority (50.0%) of the study participants had well-controlled asthma. Studies reported by Ayuk et al [11] and Omole et al [12] had similar findings with this study. Kuti and Omole [13] reported a higher percentage of 83.7% of well-controlled asthma among Ilesa children.…”

Objectives: This study aimed at assessing asthma control using Global Initiative for Asthma (GINA) asthma assessment, and determining its relationship with lung function parameters among asthmatic children in Usmanu Danfodiyo University Teaching hospital, Sokoto. Materials and Methods: This was a cross-sectional study among 60 children with asthma diagnosed based on GINA guidelines. It was conducted over a period of 4 months. The GINA asthma control assessment was administered to assess asthma control. Lung function was done using a portable spirometer. Results: Males accounted for 58.3% of the study population with M: F of 1.4:1 and median age of 9.47 years, with majority from urban domicile (91.7%). Well-controlled asthma accounted for 50.0% while 35.0% had partly controlled asthma and 15.0% had poorly controlled asthma. The median FEV1/FVC among the study participants was 0.856 (IQR: 0.170). There was no relationship between asthma control and LF parameters (FEV1: r = 0.044, P = 0.736, FVC: r = 0.010, P = 0.941, FEV1/FVC: r = 0.122, P = 0.352, and PEFR: r = 0.015, P = 0.911). Conclusion: Majority of the study participants had well-controlled asthma and no relationship was found between asthma control and lung function. Thus, serial monitoring of LF in addition to uniformly agreed standardized assessment of asthma control is required to objectively evaluate asthma control in children.

“…24 The most common concomitant atopic diseases are asthma (15% -64%), allergic rhinitis (30% -49%) and eczema (16% -24%). 19,20,25 In another earlier study, atopy was common in patients with palpebral or tarsal form of the disease compared with the limbal form. 26 Moreover, VKC is also associated with a family history of other inflammatory diseases such as psoriasis and thyroiditis.…”

“…Interestingly, this is usually attributed to consanguineous marriages. 25 This further emphasises the need for a detailed case history when examining patients with VKC in order to fully understand any possible associated causative factors of the disease.…”

Background: Vernal keratoconjunctivitis (VKC) is a public health problem that mostly affects children in warm subtropical climates. Unfortunately, the causative factors of the disease are not clearly defined, thus posing a serious management challenge to healthcare providers. It is therefore argued that understanding the pathogenesis of the disease and how various inflammatory cells affect the conjunctiva and the cornea may assist in the management of the disease.Aim: As visual impairment and avoidable blindness are indicated, it is advisable for optometrists to understand the clinical presentation of this chronic condition in order to initiate appropriate interventions and/or immediate referrals where necessary.Methods: A thorough literature search was conducted on peer-reviewed publications on VKC and children. All material obtained were then studied and the information extracted was used to document relevant information required for understanding VKC amongst children.Results: The results in the studied material revealed that VKC was prevalent amongst children aged 2 to 18 years, affecting mostly male children of African and Indian origins. Different strategies of management of the disease have been proposed, including but not limited to explaining to parents the nature of the disease, environmental strategies and preventive measures as well as possible surgical intervention.Conclusion: In view of the nature of this disease, healthcare providers should therefore seek to understand the history of the patient better when such patients present for their first consultation in order to develop a comprehensive management approach.

“…All three studies conducted in Nigeria, South Africa and Uganda [19][20][21] were cross-sectional; two hospital-based and one community-based. The sample size was smaller for hospital-based studies with 207 and 115 participants in Nigeria 19 and South Africa, 20 respectively, compared with the community-based study of 561 participants in Uganda. 21 Publication dates ranged from 2014 to 2019.…”

“…Interestingly, the children who lived in rural areas without concurrent allergy had poorly controlled asthma (50.0%) compared with their urban counterparts (28.3%), Fisher's exact test=2.076, p=0.17, although this too was not significant. 19 All three included studies considered the presence of asthma triggers in their participants' environments, but only the South African study examined these triggers in relation to asthma control. Common triggers included dust, cold air, physical exercise, fumes or air pollution, pollen, pets, smoking and biomass fuels (figure 2).…”

Barriers and determinants of asthma control in children and adolescents in Africa: a systematic review

ObjectiveTo identify reasons for poor asthma control in African children and adolescents.DesignSystematic reviewData sourcesPubMed, Scopus, CINHAL, PsycINFO, MEDLINE and Web of Science databases were systematically searched up to 31 May 2020. Hand searching was done on Sabinet, African Journal online and Google Scholar.Eligibility criteriaStudies identifying barriers to asthma control, where asthma control was assessed by the validated Asthma Control Test/Child Asthma Control Test and/or Asthma Control Questionnaire were included.Data extraction and synthesisTwo reviewers independently selected studies for inclusion with disagreements resolved by a research team discussion, including a third reviewer. Data were extracted using the Cochrane Effective Practice and Organization of Care data collection form. The quality of the included studies was assessed using the modified Newcastle-Ottawa quality assessment scale. Identified barriers were reported in a thematic narrative synthesis.Primary outcomesPoorly controlled asthma and associated factors.ResultsFrom 914 records, three studies conducted between 2014 and 2019 in Nigeria, Uganda and South Africa met the inclusion criteria. A total of 883 children aged 4–19 years were analysed. Older age, concurrent allergy and city-dwelling significantly impacted asthma control. Few children with asthma symptoms in the community had ever used inhaled corticosteroids (6.7%) and identified reasons included lack of asthma diagnosis (38.8%) and no prescribed treatment (47.6%).ConclusionAsthma control in African children is impacted by age, allergy, urbanisation and lack of access to asthma diagnosis and treatment. More studies focusing on identifying barriers to asthma control in Africa are needed.PROSPERORegistration no: CRD42020196755)

The prevalence of allergic diseases among children with asthma: What is the impact on asthma control in South East Nigeria?

Abstract: Allergic diseases are common in children with asthma in our environment, but did not significantly impact on asthma control. Socioeconomic factors such as urbanization and family size had effects on the achievement of asthma control but not on allergy status.
