Normalisation of the psychometric encephalopathy score within the Cameroonian population.

BACKGROUND: Minimal hepatic encephalopathy (MHE) is the presence of neuropsychological abnormalities detectable by psychometric tests. Psychometric Hepatic Encephalopathy Score (PHES) is a gold standard test for the early diagnosis of MHE in cirrhotic patients. The aim of this study was to standardize the PHES in a healthy Cameroonian population and to evaluate the prevalence of MHE among cirrhotic patients. METHODS: This was a prospective, multicentric study from 1 December 2018 to 31 July 2019 in two groups: healthy volunteers and cirrhotic patients without clinical signs of hepatic encephalopathy. The results of the number connection test-A, number connection test-B, serial dotting test, line tracing test were expressed in seconds and those of the digit symbol test in points. RESULTS: A total of 102 healthy volunteers (54 men, 48 women) and 50 cirrhotic patients (29 men, 31 women) were included. The mean age was 38.1 ± 12.55 years in healthy volunteers and 49.3 ± 15.6 years in cirrhotic patients. The mean years of education level was 11.63 ± 4.20 years in healthy volunteers and 9.62 ± 3.9 years in cirrhotic patients. The PHES of the healthy volunteer group was - 0.08 ± 1.28 and the cut-off between normal and pathological values was set at - 3 points. PHES of the cirrhotic patients was - 7.66 ± 5.62 points and significantly lower than that of volunteers (p < 0.001). Prevalence of MHE was 74% among cirrhotic patients. Age and education level were associated with MHE. CONCLUSION: PHES cut-off value in Cameroonians is - 3, with MHE prevalence of 74% among cirrhotic patients.

Coronavirus Disease 2019 (COVID-19) as a Multi-Systemic Disease and its Impact in Low- and Middle-Income Countries (LMICs).

Currently, the coronavirus disease 2019 (COVID-19) is the priority of the global health agenda. Since the first case was reported in Wuhan, China, this infection has continued to spread and has been considered as a pandemic by the World Health Organization (WHO) within 3 months of its outbreak. Several studies have been done to better understand the pathogenesis and clinical aspects of the disease. It appears that COVID-19 affects almost all body organs due to the direct effect of the virus and its induced widespread inflammatory response. This multi-systemic aspect of the disease has to be inculcated in COVID-19 management by health providers to improve patient outcomes. This strategy could help curb the burden of the disease especially in low- and middle-income countries (LMICs) like most African countries where the pandemic is at an "embryonic" stage.

[Cryoglobulin and factors associated with it in patient with anti-hepatitis-C antibodies living in resource-limited countries]. / Cryoglobuline et facteurs associés chez le patient porteur de l'anticorps du virus de l'hépatite C dans un pays à ressources limitées.

INTRODUCTION: hepatitis C virus (HCV) has several extra-hepatic manifestations including cryoglubulinemia. Cryoglobulinemia is defined as the abnormal presence in the blood of one or several proteins (cryoglobulins) that can precipitate at low temperatures. METHOD: We conducted a cross-sectional analytical study in the Laboratory of Biology and in the Unit of Hepatology of the General Hospital in Douala (HGD) over a period of 6 months. All patients agreeing to participate to the study and with anti-hepatitis-C antibodies under treatment or not were enrolled. Cryoglobulins were detected using biuret method and the classification was performed using Brouet immunoelectrophoresis. A multivariate analysis was conducted, confounding factors such as age, sex and the length of time after Hepatitis C Virus screening were adjusted. RESULTS: The study enrolled 116 patients. The average age of patients was 58.47±9.95 years. Male sex accounted for 50.86% of cases. Arthralgia was found in 69.80% of cases. Cryoglobulin was found in 63.80% of patients. After adjustment, female sex (OR =2.18; CI 95% [0,97-4,90]; p= 0.059), asthenia alone (OR =2.45;CI 95% [1,04-5,80]; p= 0.041), asthenia combined with arthralgia (OR =2.84;CI 95% [1,13-7, 10]; p= 0.026) and the presence of HCV RNA (OR =2.84;CI 95% [1,13-7,10]; p= 0.028) were factors independently associated with the presence of cryoglobulin. CONCLUSION: The prevalence of cryoglobubin is high in patients with anti-hepatitis-C antibodies at the HGD. Simple biological methods are used to detect it. Cryoglobulin test in patients with HCV is essential in resource-limited countries.

[Prognosis and survival of esophageal cancer in Cameroon: a prognostic study]. / Facteurs pronostiques du cancer de l'œsophage au Cameroun: étude multicentrique.

INTRODUCTION: Esophageal cancer is rare. Poor prognosis is due to delayed diagnosis. Five year survival is less than 20%. This study aimed to investigate the factors associated with survival of patients with esophageal cancer in Cameroon. METHODS: We conducted a prognostic study in the General Hospitals in Yaoundé and in Douala over a period of 11 years from 1 January 2005 to 31 December 2015. The parameters studied were those associated with survival. Survival was established on the basis of the date of diagnosis and of the date of death or of the last visit. SPSS software (Statistical Package for Social Sciences) version 23 allowed for data analysis. Kaplan Meier curve was used to estimate the survival function. Log RankTest allowed for comparison among the different groups. Cox regression helped to highlight the different factors associated with it. Significance level was set at 0.05. RESULTS: We collected data from 49 medical records. The average age of patients was 57.83 years. There was a male predominance (71.4%; n=35) with a sex ratio of 2.49. The follow-up period was 3.2 months. Median survival was 6.67 months (CI 95% [1.33-10.4]) and the average survival time was 7.99 months (CI 95% [4.42-11.17]). Multivariate-adjusted analysis showed that stage IV was a predictive factor of mortality (HR = 2.79; CI95% [1.13-6.89], p = 0.025]). CONCLUSION: Esophageal cancer is a rare disease with poor prognosis. Prognostic factor is the tumor stage.

Cryoglobuline et facteurs associés chez le patient porteur de l'anticorps du virus de l'hépatite C dans un pays à ressources limitées

Introduction: le virus de l'hépatite C (VHC) a plusieurs manifestations extra hépatiques parmi lesquelles la cryoglubulinémie. La cryoglobulinémie se définit par la présence anormale dans le sang d'une ou plusieurs protéines (cryoglobuline) pouvant précipiter au froid. Méthodes: nous avons mené une étude transversale et analytique dans le service du laboratoire de biologie et l'unité d'hépatologie de l'Hôpital Général de Douala (HGD) pendant une durée de 6 mois. Etaient inclus dans le travail tous les patients acceptant de participer et porteurs d'un anticorps anti VHC avec ou sans traitement. Les cryoglobulines étaient recherchés par la méthode de Biuret et la classification était réalisée par une immunoélectrophorèse de Brouet. Une analyse multivariée a été réalisée, des facteurs de confusion tels que l'âge, le sexe et la durée après dépistage du VHC ont été ajustés.Résultats: nous avons inclus 116 patients. L'âge moyen était de 58,47 ± 9,95 ans. Le sexe masculin représentait 50,86% des cas. L'arthralgie était présente dans 69,80% des cas. La cryoglubiline était présente chez 63,80% des cas. Apres ajustement, le sexe féminin (ORa =2,18; IC à 95% [0,97-4, 90]; p= 0,059), l'asthénie seule (ORa =2,45; IC à 95% [1,04-5,80]; p= 0,041), l'asthénie couplée à l'arthralgie (ORa =2,84; IC à 95% [1,13-7, 10]; p= 0,026) et la présence de l'ARN du VHC (ORa =2,84; IC à 95% [1,13-7, 10]; p= 0,028) étaient des facteurs indépendamment associés à la présence de cryoglobuline.Conclusion: la prévalence de la cryoglobubine est élevée chez les patients porteurs de l'Ac anti VHC à l'HGD. Elle est recherchée par les méthodes biologiques simples. La recherche de cryoglobuline chez les patients porteurs du VHC est essentielle dans un pays à ressource limité

Effects of phloroglucinol on the active phase of labour (EPAL trial): a single blinded randomised controlled trial in a tertiary hospital in sub-Sahara Africa.

INTRODUCTION: One of the most recognized factors of maternal and neonatal outcome pertaining to the peripartum period is the duration of labour. Finding a drug that will decrease the duration of labour with no effects on mother and foetus will be welcomed. Thereby in this study we aimed to evaluate the effects of phloroglucinol on the duration of the active phase of labour. METHODS: We did a single blinded placebo controlled randomised 1:1 parallel designed superiority trial between January and June 2017 in Douala general hospital. Participants greater than 18 years with singleton uncomplicated pregnancy who consented following randomisation, were administered either 80mg/8ml intravenous phloroglucinol or 8ml of sterile water when in active labour. The primary outcome was the duration of labour. Modified intention to treat analysis was done with the level of significance set at a p value of 0.05. RESULTS: 122 participants received the intervention. The mean total duration labour in the treatment and placebo group were 216.8 ± 38.7 and 358.5 ± 65.8 respectively (p value = 0.243). The mean duration of the active phase of labour in the treatment and placebo group were 183.0±35.6 and 316.0±52.2 respectively (p value = 0.046). The mean rate of cervical dilatation in the treatment and placebo group were 2.1 ± 0.4 and 1.3 ± 0.4 respectively (p value = 0.322). There was no difference in maternal and foetal outcomes between the two groups. CONCLUSION: Phloroglucinol shortens the duration of active phase of labour by about 2 hours (42%). It is safe to mother and baby and does not cause adverse foetal or maternal outcomes.
