C-Reactive Protein and Covid-19 Severity: A Systematic Review.

BACKGROUND: COVID-19 clinical course has been quite unpredictable and efforts have been made to identify reliable markers that will help in early disease progression, prognosis and severity detection. Objective: This study thus aimed to provide evidence that will guide clinical management by reviewing studies that assessed CRP concentration and COVID-19 severity/outcome. METHODS: Three electronic databases, PubMed/Medline, Google Scholar, and JSTOR were searched to identify studies available online as at 1st September 2020 which assessed COVID-19 clinical outcome and CRP concentration. The search strategy involved words combination like "C-reactive protein" OR "inflammatory markers" OR "acute phase reactants" and "coronavirus 2019" OR ''COVID-19" OR "2019-nCoV" OR "SARS-CoV-2". RESULTS: Sixty-one articles were systematically reviewed out of 812 studies identified after duplicates were removed. The 61 studies comprised 13,891 COVID-19 patients made of 7,840 (56.4%) males and 6,051 (43.6%) females. All the papers revised were observational studies except one case-control and they cut across fifteen countries. The result of the review demonstrated that the severe cases had higher levels of C - reactive protein when compared to the mild cases in all the studies (100%). The increase in C-reactive protein was statistically significant in 78.7% of the cases. CONCLUSION: High levels of CRP are associated with COVID-19 severity. Highlights: Severe cases of COVID-19 is characterized with higher CRP levels. COVID-19 cases should be screened regularly for CRP to monitor severity.

Contexte: L'évolution clinique du COVID-19 a été assez imprévisible et des efforts ont été faits pour identifier des marqueurs fiables qui aideront à la progression précoce de la maladie, au pronostic et à la détection de la gravité. Objectif : Cette étude visait donc à fournir des preuves qui guideront la gestion clinique en passant en revue les études qui ont évalué la concentration de CRP et la gravité/l'issue du COVID-19. Méthodes: Trois bases de données électroniques, PubMed/Medline, Google Scholar et JSTOR, ont été consultées pour identifier les études disponibles en ligne au 1er septembre 2020 qui évaluaient le résultat clinique du COVID-19 et la concentration de CRP. La stratégie de recherche comportait des combinaisons de mots comme "protéine Créactive" OU "marqueurs inflammatoires" OU "réactifs de phase aiguë" et "coronavirus 2019" OU "COVID-19" OU "2019-nCoV" OU "SARS-CoV-2". Résultats: Soixante et un articles ont été systématiquement examinés sur les 812 études identifiées après suppression des doublons. Les 61 études comprenaient 13 891 patients atteints de COVID-19, dont 7 840 (56,4 %) hommes et 6 051 (43,6 %) femmes. Tous les articles examinés étaient des études d'observation, à l'exception d'un cas-témoin, et ils couvraient quinze pays. Le résultat de l'examen a démontré que les cas graves avaient des niveaux plus élevés de protéine C-réactive par rapport aux cas légers dans toutes les études (100%). L'augmentation de la protéine C-réactive était statistiquement significative dans 78,7% des cas. Conclusion: Des niveaux élevés de CRP sont associés à la sévérité du COVID-19. Mots clés: Protéine C-réactive, COVID-19, SRAS-COV-2 et Coronavirus. Points forts: Les cas graves de COVID-19 sont caractérisés par des niveaux de CRP plus élevés. · Les cas de COVID-19 doivent faire l'objet d'un dépistage régulier de la CRP afin de surveiller la gravité de la maladie.

Assessment of gross malnutrition among primary school children using body mass index as an assessment tool in abakaliki metropolis of Ebonyi State, South-East Nigeria.

BACKGROUND: Obesity and overweight are emerging major health problems in developing countries in the background of undernutrition. These have been linked to a substantial increase in mortality and morbidity. OBJECTIVES: This cross-sectional survey was aimed at determining the prevalence of underweight, overweight, and obesity using body mass index (BMI) in primary school pupils in Abakaliki metropolis of Ebonyi State, south-east Nigeria. METHOD: Eight hundred and four participants aged 6-12 years, from four public and four private primary schools had their weights and heights measured using standard methods. BMI value was calculated for each subject and compared with BMI for age and sex from World Health Organisation (WHO 2007) reference standard. Socioeconomic status was determined using method proposed by Oyedeji. RESULTS: Out of 804 subjects, 426 (53.0%) were from public schools, whereas 378 (47%) were from private schools (P ≤ 0.01). Four hundred and fifteen (51.6%) were males and 389 (48.4%) were female (P = 0.88). The prevalence of underweight, overweight, and obesity using BMI were 4.5% and 1.2%, 0% in public schools and 1.1%, 5.0%, and 3.0% in private schools, (P < 0.001). The socioeconomic class significantly affected the prevalence of underweight, overweight, and obesity as more subjects with overweight and obesity belonged to upper social class, whereas more underweight subjects belonged to lower social class. CONCLUSION: Overweight and obesity are emerging in a background of undernutrition, showing ''double burden'' of nutritional disorder.
