Preliminary Study on Open Labelled Randomized Controlled Trial of the Safety and Efficacy of Hydroxychloroquine and Chloroquine Phosphate for the Treatment of Persons Infected with 2019 Coronavirus Disease in Nigeria.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a causative agent of COVID-19 is a leading cause of ill-health and deaths worldwide. Currently, COVID-19 has no known widely approved therapeutics. Thus, the need for effective treatment. OBJECTIVES: We investigated the safety and efficacy of two (2) therapeutic agents; chloroquine phosphate (CQ), 2- hydroxychloroquine (HCQ) and a control (standard supportive therapy) among hospitalized adults with COVID-19. METHODS: The clinical trial was done in accordance to the World Health Organization master protocol for investigational therapeutics for COVID-19. Atotal of 40 participants with laboratory-confirmed positive COVID-19 were enrolled. Blood samples and oropharyngeal (OP) swabs were obtained on days 1,3,15 and 29 for safety and efficacy assessments. RESULTS: The baseline demographics showed that the median ages in years (range) were 45 (31-57) in CQ, 45 (36.5-60.5) in HCQ, 43 (39.5-67.0) and 44.5 (25.3-51.3) in the control (P<0.042).At randomization, seven (7) participants were asymptomatic, thirty-three (33) had mild symptoms, eight (8) had moderate symptoms while three (3) had severe symptoms. The average day of conversion to negative COVID-19 was 15.5 days for CQ, 16 days for HCQ and 18 days for the control(P=0.036). CONCLUSION: The safety assessment revealed no adverse effect of the drugs in COVID-19 patients after treatment. These findings proved that chloroquine and hydroxychloroquine are effective for the treatment of COVID-19 among hospitalized adults. It also confirmed that they are safe.

Clinical predictors of Covid-19 mortality in a tertiary hospital in Lagos, Nigeria: A retrospective cohort study.

Background: The predictors of mortality among patients presenting with severe to critical disease in Nigeria are presently unknown. Aim: The aim of this study was to identify the predictors of mortality among patients with COVID-19 presenting for admission in a tertiary referral hospital in Lagos, Nigeria. Patients and Methods: The study was a retrospective study. Patients' sociodemographics, clinical characteristics, comorbidities, complications, treatment outcomes, and hospital duration were documented. Pearson's Chi-square, Fischer's Exact test, or Student's t-test were used to assess the relationship between the variables and mortality. To compare the survival experience across medical comorbidities, Kaplan Meir plots and life tables were used. Univariable and multivariable Cox-proportional hazard analyses were conducted. Results: A total of 734 patients were recruited. Participants' age ranged from five months to 92 years, with a mean ± SD of 47.4 ± 17.2 years, and a male preponderance (58.5% vs. 41.5%). The mortality rate was 9.07 per thousand person-days. About 73.9% (n = 51/69) of the deceased had one or more co-morbidities, compared to 41.6% (252/606) of those discharged. Patients who were older than 50 years, with diabetes mellitus, hypertension, chronic renal illness, and cancer had a statistically significant relationship with mortality. Conclusion: These findings call for a more comprehensive approach to the control of non-communicable diseases, the allocation of sufficient resources for ICU care during outbreaks, an improvement in the quality of health care available to Nigerians, and further research into the relationship between obesity and COVID-19 in Nigerians.

Outcome of Patients with Common Endocrine Diseases Who Had COVID-19 in two Centers in Lagos, Nigeria: A Cross-Sectional Study.

BACKGROUND: Endocrine diseases are ubiquitous. In our environment, diabetes mellitus (DM), obesity and thyroid disorders represent the most common examples. Diabetes mellitus is a global health problem with a myriad of complications. We sought to evaluate outcome in terms of fatality in those with common endocrine diseases who were infected with COVID-19. AIMS AND OBJECTIVES: To determine outcome in terms of mortality in patients with common endocrine diseases who contracted COVID-19. MATERIALS AND METHODS: We conducted an observational, descriptive, cross-sectional study with 120 participants drawn from the endocrinology/DM clinic at the Lagos University Teaching Hospital and Serenity Hospital, Surulere (a private medical clinic). Data collected included age, gender, type of endocrine disease, comorbid diseases, and COVID-19 status. Through charts from the medical records department, outcome of participants in terms of mortality was determined. RESULTS: Data of 120 subjects were analyzed. There were 61males and 59 females, yielding a male:female ratio of 1:1. Mean age was 58 years and the mode was 46 years. Over half (88) of the patients had diabetes mellitus, 22 had obesity, and 17 had thyroid disorders. The case fatality rate of patients with endocrine diseases who had COVID-19 was 11%, with about 85% of these deaths occurring in the elderly (those aged above 60 years). Ninety-two percent of the patients who died had type 2 DM. Approximately 80% of patients who were infected with COVID-19 had at least one co-morbid disease. CONCLUSION: Older age, type 2 diabetes mellitus, and the presence of at least one comorbidity were associated with increased mortality in patients with endocrine diseases who were infected with COVID-19 in our study.

CONTEXTE: Les maladies endocriniennes sont omniprésentes. Dans notre environnement, le diabète sucré, l'obésité et les troubles thyroïdiens en sont les exemples les plus courants. Le diabète est un problème de santé mondial qui s'accompagne d'une myriade de complications. Nous avons cherché à évaluer l'issue en termes de mortalité chez les personnes atteintes de maladies endocriniennes courantes qui ont été infectées par COVID-19. BUTS ET OBJECTIFS: Déterminer l'issue en termes de mortalité chez les patients atteints de maladies endocriniennes courantes qui ont contracté COVID 19. MATÉRIEL ET MÉTHODOLOGIES: Nous avons mené une étude observationnelle, descriptive et transversale auprès de 120 participants provenant de la clinique d'endocrinologie/DM de l'hôpital universitaire de Lagos et de l'hôpital Serenity, Surulere (clinique médicale privée). Les données recueillies comprenaient l'âge, le sexe, le type de maladie endocrinienne, les maladies concomitantes et le statut COVID-19. Les résultats des participants en termes de mortalité ont été déterminés à partir des dossiers médicaux. RÉSULTATS: Les données de 120 sujets ont été analysées. Il y avait 61 hommes et 59 femmes, avec un ratio homme/femme de 1:1. L'âge moyen était de 58 ans, le mode de 46 ans. Plus de la moitié [88] des patients souffraient de diabète sucré. 22 patients souffraient d'obésité et 17 de troubles thyroïdiens. Le taux de létalité des patients souffrant de maladiesendocriniennes et atteints de COVID-19 était de 11 %, 85 % de ces décès survenant chez des personnes âgées, c'est-à-dire de plus de 60 ans. 92 % des patients décédés souffraient de diabète de type 2. Environ 80 % des patients infectés par COVID-19 présentaient au moins une maladie concomitante. CONCLUSION: L'âge avancé, le diabète de type 2, la présence d'au moins une comorbidité sont associés à une mortalité accrue chez les patients atteints de maladies endocriniennes et infectés par COVID-19 dans notre étude.

Clinical Presentation and Intensity of Infection with Intestinal Helminths among School Children in Ile-Ife, Osun State, Nigeria.

BACKGROUND: Intestinal helminthiases are public health problems of children in developing countries of the world and account for significant morbidity as it results in stunted growth, intestinal obstruction, anaemia, cognitive impairment, acute pancreatitis, acute cholecystitis and rectal prolapse. This study assessed intestinal helminths, infection intensity and symptoms in primary school children in Ile-Ife. METHODS: It was a cross sectional study. Three hundred and eighty-four pupils randomly selected from six public primary schools in Ife Central Local Government were enrolled for the study. Ethical approval was obtained. Stool samples were collected and processed using the Formol-ether concentration method. Questionnaires were administered to obtain relevant information. Data entry and processing were done using Microsoft excel and IBM SPSS Statistics for windows, version 17. Statistical analysis included frequency, proportion and percentages. RESULTS: Helminthic parasites were recovered from the stool of the schoolchildren and the overall prevalence of helminthic infection was 24%. Ascaris lumbricoides was the most prevalent (22.1%) with moderate and light intensities of infection, Hookworm (3.4%) with light intensity infection and Hymenolepis nana 0.3%. Symptoms were present in 48.2% of the participants and 31.5% presented with abdominal pain, nausea 22.1%, diarrhoea 21.1%, anorexia 7%. Weight loss, nausea and vomiting were found to be significantly associated with infection with intestinal helminths. CONCLUSION: Light to moderate intestinal helminthic infections are still prevalent among school children with weight loss, nausea and vomiting being the most significant symptoms. Continuous studies among school children are needed including those in private schools to better understand the epidemiology of these infections.

BACKGROUND: Les helminthiases intestinales sont des problèmes de santé publique, des enfants dans les pays en voie de développement du monde et représentent une morbidité importante, car elles entraînent un retard de croissance, l'obstruction intestinale, l'anémie, les troubles cognitifs, la pancréatite aiguë, la cholécystite aiguë et prolapsus rectal. Cette étude a évalué les helminthes intestinaux, l'intensité de l'infection et les symptômes chez les enfants des écoles primaires d'Ile-Ife. MÉTHODES: Il s'agissait d'une étude transversale. Trois cent quatre-vingt-quatre élèves choisis au hasard dans six écoles primaires publiques de Ife Central Local Government ont été recrutés pour l'étude. L'approbation éthique a été obtenue. Les échantillons de selles ont été collectés et traités en utilisant la méthode de concentration Formol-Ether. Des questionnaires ont été administrés pour obtenir des informations pertinentes. La saisie et le traitement des données ont été effectués à l'aide de Microsoft Excel et IBM SPSS. Statistique pour wndows, version 17. L'analyse statistique comprenait fréquence, proportion et pourcentages. RÉSULTATS: Les parasites helminthiques ont été récupérés dans les selles des écoliers et la prévalence globale de l'infection helminthique était de 24%. Ascaris lumbricoides était le plus répandu (22,1%) avec une intensités d'infection modérée et légère, l'ankylostome (3,4%) avec une intensités d'infection légère et Hymenolepis nana 0,3 %. Les symptômes étaient présents chez 48,2% des participants et 31,5% présentaient des douleurs abdominales, nausées 22,1%, diarrhées 21,1%, anorexie 7%. La perte de poids, les nausées et les vomissements ont été associés de manière significative à l'infection par des helminthes intestinaux. CONCLUSION: Les infections légères à modérées par les helminthes intestinaux sont encore répandues chez les écoliers, la perte de poids, les nausées et les vomissements étant les symptômes les plus significatifs. Des études continues parmi les enfants scolarisés, y compris dans les écoles privées, sont nécessaires pour mieux comprendre l'épidémiologie de ces infections.

Medical mortality in an emergency department in Nigeria: the transition is obvious!

INTRODUCTION: The emergency department (ED), a major entry point into the hospital, provides an insight to the type of cases seen, the quality of care and mortality spectrum in a health institution. We aim to identify the spectrum of medical causes of mortality in our ED, the demographic pattern and duration of stay before death. METHOD: This is a retrospective study that looked at medical mortality in the ED from January 2004 to December 2009. We obtained data on the demographics and causes of death from the medical records and case notes of the deceased. RESULTS: A total of 16587 patients were admitted during the period under review, of these 1262 (7.61%) died in the ED. The male to female ratio was 1.58:1.0 [772 males (61.2%), and 489 females (38.8%)]. Mortality was highest among the 20-45 years age range, followed by 46-65 years, >65 years and < 20 years in decreasing frequency [589(46.7%), 421(33.4%), 186 (14.8%) and 66(5.2%) respectively]. The three most common causes of death were stroke 315(25%), HIV related illnesses 126(10.0%), and heart failure 123(9.7%). Most deaths occurred less than 24hours of admission, 550(43.6%), followed by one day (36.0%) and two days (10.8%) post admissions respectively. CONCLUSION: The commonest cause of death in the ED was stroke. The burden of death was highest in the younger age group, with most occurring less than 24 hours of admission.
