- ItemChronic obstructive pulmonary disease (COPD) : neutrophils, macrophages and lymphocytes in patients with anterior tuberculosis compared to tobacco related COPD(BioMed Central, 2018-03-27) Guiedem, Elise; Ikomey, George Mondinde; Nkenfou, Celine; Walter, Pefura-Yone Eric; Mesembe, Martha; Chegou, Novel N.; Jacobs, Graeme Brendon; Okomo Assoumou, Marie ClaireObjective: The inflammatory profile of chronic obstructive pulmonary disease (COPD) related to tobacco is known in certain studies while that of the post tuberculosis form is not yet known. This study aimed to evaluate the levels of neutrophils, macrophages and lymphocytes cells in sputum of COPD patients with history of smoking or anterior tuberculosis. Enumeration of cells in samples was analyzed using standard microscopy. Results: We enrolled 92 participants, 46 (50%) were COPD subjects comprising 22 (47.83%) smokers and 24 (52.17%) with anterior tuberculosis while 46 (50%) healthy persons constituted the control group. The levels of neutrophils, lymphocytes and monocytes were statistically higher in COPD patients compared to the control group with p-values of 0.0001 respectively. Neutrophils levels were higher in COPD patients with history of tobacco than in COPD patients with anterior tuberculosis with a mean rate of 4.72 × 106/ml and 2.48 × 106/ml respectively (p = 0.04). The monocytes and lymphocytes levels were not statistically different between the two sub-groups of COPD patients with p-value of 0.052 and 0.91 respectively. Neutrophils are the only inflammatory cells that were significantly higher in COPD patients with history of smoking as compared to COPD patients with anterior tuberculosis.
- ItemEvidence of co and triple infections of Hepatitis B and C amongst HIV infected pregnant women in Buea, Cameroon(Science Publishing Group, 2016-03) Ikomey, George Mondinde; Jacobs, Graeme Brendon; Tanjong, Becky; Mesembe, Martha Tongo; Eyoh, Agnes; Lyonga, Emilia; Mfoataw, Ebot; Ngoh, Rose; Tamandjou Tchuem, Cynthia Raissa; Ikomey, Greg; Okomo Assoumou, Marie ClaireLittle epidermiological data is available on the prevalence of HIV, Hepatitis B and C, Co-and or triple infection during pregnancy in Cameroon as well as many other resource limited settings. HIV and Hepatitis B and C are major public health concerns world wide. Our study aimed at assessing the seroprevalence of Hepatitis B and C amongst HIV infected pregnant women in Buea, located in the Southwest region of Cameroon. A Cross-sectional study on consented pregnant women were conducted from March 2015 to August 2015. HIV-1 infections were detected using the national HIV-1 test algorithms. Hepatitis B surface antigen (HBsAg), anti-HBe and anti- Hepatitis C (anti-HCV) were detected using Enzyme linked Immunosorbent Assays (ELISAs). Of the 1230 recruited pregnant women, 97/1230 (7.8%) (95% CI: 3.5, 29.0%) were confirmed HIV-1 positive. HIV/HBV co-infection were observed in 14/97 (14.4%) (95% CI: 39.8, 100%), whilst 11/97 (11.3 %; 95% CI: 27.5, 100%) were HIV/HCV co-infections. Two HIV-infected pregnant women (8/97(8.2%; 95% CI: 0.1, 17.2%)) were HIV/HBV/HCV triple-infected. Anti-HBc was detected in all HBV-infected pregnant women (14/14; (100.0%)) (95.0% CI: 39.8, 100.0%). Seropositivity for HIV-1 was higher (37%) amongst subjects aged between 32-37 years, whilst none was found above 40. From our results we conclude that Co- and triple infections of HIV, Hepatitis B and C were present amongst pregnant women in Buea. Epidemiological data generated from this study are limited due to the existence of triple infected. It will therefore serve as a guide to the government policies to reinforce screening, treatment and prevention strategies, through its Mother–to-Child–transmission (pMTCT) Programme nationwide.
