NCT ID: NCT04737473 Recruiting - Surgery Clinical Trials

The Comparative Efficacy and Safety of Two General Anesthesia Protocols Consisting of Fentanyl Plus Propofol Plus Rococuronium Plus Isoflurane Versus Ketamime Plus Magnesium Sulphate Plus Lidocaine Plus Clonidine Plus Propofol Plus Rococuronium Plus Isoflurane for Gynaecology Surgery in Cameroon

Start date: January 6, 2020
Phase: N/A
Study type: Interventional

Recently, a lot of side effects have been identified from the perioperative use of opioids. To remedy this, anesthesia research has recently focused on providing safe general anesthesia without opioids in a new concept or anesthetic technic called Opiod Free Anesthesia (OFA). Evidence on the effectiveness and safety of OFA is scarce in Africa, with no report from Cameroon.The aim of this study is to demonstrate the feasibility of an adapted OFA protocol as well as its efficacy and safety in very painful surgeries like gynaecology surgery in a low-resource setting.

This is an exploratory study to evaluate the efficacy of Doxycycline (200mg on D1 to D7) and Rivaroxaban (15 mg daily on D1 to D7) versus the combination of Hydroxychloroquine (400 mg on D1 to D7) and Azithromycin (500 mg on D1 and 250mg on D2 to D5) as per national standard to treat ambulatory mild COVID-19 patients, with the aim to achieve early negativity of RT-PCR of SARS-CoV-2 from nasopharyngeal swab, and early clinical improvement and prevention of severe disease.

NCT ID: NCT04682990 Recruiting - Clinical trials for Tuberculosis, Pulmonary


Start date: January 5, 2021
Phase: N/A
Study type: Interventional

Tuberculosis (TB) is one of the top 10 causes of death in the world. More than 95% of TB deaths are in middle- and middle-income countries. Low incomes and long-term diagnosis promote this persistence. In 2017, Cameroon was the 3rd in the top of 20 countries with the highest estimated numbers of incident TB cases among people living with HIV, based on the severity of their TB burden. World Health Organization (WHO) encourages the introduction of rapid, non-invasive and cheaper screening tests. In this scope, this study proposes the collection of exhaled breath samples and their analysis through the electronic nose made in Tor Vergata University (TV eNose) to diagnose TB and TB-HIV on their participants.

NCT ID: NCT04565184 Completed - Malaria,Falciparum Clinical Trials

Effectiveness and Safety of Artesunate-Amodiaquine and Artemether-Lumefantrine for the Treatment of Malaria in Yaounde

Start date: May 9, 2019
Phase: Phase 4
Study type: Interventional

Artesunate-amodiaquine and artemether-lumfantrine are currently being used for the treatment of uncomplicated Plasmodium falciparum in Cameroon. Globally, many studies have reported high efficacy and safety of artemisinin-based combination therapies (ACTs) mostly under strict supervision of drug intake and limited to children less than 5 years of age. Patients over 5 years of age are usually not involved in such studies. The main objective of this study is to assess the genetic markers of antimalarial drug resistance and drug metabolism subsequent to the efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine during a 28-day follow-up period in children with acute uncomplicated P. falciparum malaria in Yaounde, Cameroon. A randomized, open-labelled, controlled clinical trial comparing artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) will be carried out from 9th May 2019 to 30th November 2020 at two secondary health centres (Cité Verte and Minkoameyos) in Yaounde. The study participants shall include febrile patients aged 6 months to 10 years, with confirmed uncomplicated P. falciparum infection. Eligible children for whom parent/guardian informed consents are obtained will be randomized to receive either artesunate-amodiaquine (group A) or artemether-lumefantrine (group B) in the ratio 1:1. A minimum sample of 76 patients will be required for the study. With a 20 % increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 92 patients will be enrolled for each of the two study arms. The study will recruit a total of 184 patients. Drug intake will be partially supervised only for the first dose and subsequent doses administered unsupervised as pertains in routine practice in the field. Patients or their parents/guardians will be advised on the time and mode of administration for the 3 days (D0, D1 and D2) treatment unobserved at home. Follow-up visits will be performed on days 3, 7, 14, 21, and 28 to evaluate clinical and parasitological resolution of their malaria episode as well as adverse events. Polymerase chain reaction (PCR) genotyping of merozoite surface proteins 1 and 2 (msp-1, msp-2) as well as glutamate rich protein (GLURP) will be used to differentiate between recrudescence and new infection.

NCT ID: NCT04547738 Recruiting - Tuberculosis Clinical Trials

Influence of Filarial Infections on Tuberculosis Disease and Tuberculosis Vaccination in Cameroon

Start date: November 1, 2020
Study type: Observational

Filarial nematodes modulate the host immune response to promote regulatory and T helper type 2 immune responses, which were shown to influence concomitant infections. Indeed, several studies showed that increased susceptibility and worsened disease course of HIV, tuberculosis (TB) and malaria in filarial endemic regions. Moreover, the investigators demonstrated that M. perstans infections polarize and suppress immune responses with likely consequences for concomitant infections and vaccine-induced protection. In addition, the investigators observed altered frequencies of natural killer and regulatory T and B cells in filarial and M. tuberculosis co-infected individuals and that M. perstans influences CD4+ T cell function and immune responses upon purified protein derivative antigen stimulation. Nevertheless, the consequences of manifestation of TB disease and influence on TB vaccination remains unknown. Thus, the trial aim to address two main questions with high clinical relevance: 1) Does filarial infection influence disease severity and recovery in tuberculosis patients? 2) Does filarial infection influence Bacille Calmette-Guérin (BCG)-induced protection against disease progression in vaccinated children?

NCT ID: NCT04401670 Completed - Cervical Cancer Clinical Trials

Cervical Cancer Screening in Cameroon

Start date: April 25, 2017
Phase: N/A
Study type: Interventional

Human immunodeficiency virus-infected (HIV[+]) women have a several-fold increased risk of invasive cervical cancer (ICC) as well as increased risk of cervical pre-cancer. In low- and middle-income countries (LMICs), ICC is the 1st or 2nd most common cause of cancer and cancer-related death in women. Rates of ICC and ICC-related mortality are particularly high in Sub-Saharan Africa, which also has the highest rates of HIV infection in the world. Although prophylactic HPV vaccines may be the optimal cervical cancer prevention strategy, 2-3 generations of at-risk HIV[+] and HIV[-] women are already highly exposed to human papillomavirus (HPV) and would not benefit from (and will not be immunized with) HPV vaccine. Thus cervical cancer screening is needed for the foreseeable future. However, Pap testing is expensive and requires a complex clinical and lab infrastructure that does not generally exist in LMICs; strategies based on high-risk HPV (hrHPV) testing or visual inspection after acetic acid (VIA) are promising but are either too non-specific, leading to over-referral for colposcopy or over-treatment, or are too insensitive, respectively. Thus, inexpensive, easily implemented, and effective cervical cancer screening methods are greatly needed in Sub-Saharan Africa, especially for HIV[+] women. This cervical cancer screening study of 1,200 women (800 HIV[+] and 400 HIV[-] women), aged 25-59 years, living in Cameroon, utilized our existing research site. The investigators evaluated screening tests (hrHPV testing, VIA and Pap), traditional triage tests (HPV16/18/45 detection, VIA, Pap), and promising new biomarkers for triage (Ki-C67, TOP2a, CDKN2A, and HPV viral load) of screen-positive women. All screen positives underwent rigorous disease ascertainment to obtain unbiased estimates of sensitivity, specificity, and positive and negative predictive value. The goal of this study was to establish the foundation and capacity for future studies designed to reduce the burden of HPV-associated cancers in the Cameroon population. It will inform Cameroon and other countries with high HIV burdens on the best strategies for cervical cancer screening in their HIV[+] and HIV[-] women.
