Liver and Kidney Biochemical Profile of Typhoid Fever Patients at the Dschang District Hospital, West Cameroon: A Cross-Sectional Study

Background: Typhoid fever remains prevalent in developing countries and most often affects liver and kidney. This study aimed to assess biochemical disturbances of the liver and kidney in patients with typhoid fever at the Dschang District Hospital, appreciate the implication of the disease duration as well as the type and the duration of treatment.Methods and materials:  This cross-sectional study was conducted at the Dschang District Hospital, Cameroon. A total of 263 participants and a structure questionnaire was used to collect sociodemographic data. Stool culture was used for the diagnosis of typhoid fever. Liver and kidney biomarkers were access using spectrophotometric technic. Results: By these technics, 112 healthy individuals (Control Group, CG), and 151 patients diagnosed with typhoid fever (Study Group, SG) were obtained. A significant lower level of albumin (p<0.05) was noted in SG compare to CG while other biochemical parameters of the liver and kidney function (ALT, AST, T-BILI, C-BILI, ALP, γ-GT, urea and creatinine) presented a significant higher levels at varying degrees, especially for ALT (p <0.001), AST, ALP, urea and creatinine (p <0.01), T-BILI, C-BILI and γ-GT (p <0.05). Relatively to the variation of biochemical parameters with respect to the duration of illness in the patients before their arrival to the hospital, except albumin which had a significant (p<0.05) decreased level from the first to the third week of the disease, ALT and AST had a significant (p<0.05) increased level from the first to the third week of the disease and, T-BILI, C-BILI, UC-BILI, ALP and γ-GT from the second to the third week of the disease. Relatively to the type of drug intake, the serum level of ALT, γ-GT, albumin and creatinine were significantly increased (p<0.05) with fluoroquinolones and indigenous (medicinal plants) intake while the serum level of AST, T-BILI, C-BILI, UC-BILI, ALP, urea and creatinine clearance were significantly (p<0.05) increased only with indigenous intake. Relatively to the duration of treatment, except creatinine clearance that significantly (p<0.05) decreased at the third week of treatment, the serum level of ALAT, ASAT, C-BILLI, ALP, γ-GT and albumin were significantly (p<0.05) increased from the first to the third week of the treatment, the serum level of T-BILI, UC-BILI and urea from the second to the third week of the treatment, and the serum level of creatinine at the third week of the treatment. There was a significant correlation between disease duration, drug intake duration and the serum level of ALT, AST, total bilirubin, conjugated bilirubin, unconjugated bilirubin, ALP, γ-GT, urea, creatinine, albumin and creatinine clearance. Conclusion: The results of this study suggest that typhoid fever negatively affects the proper functioning of the liver and kidneys, which varies depending on the duration of the illness, self-medication with conventional drugs such as fluoroquinolones and medicinal plants, and the duration of treatment

COMPARISON OF PERFORMANCE OF TWO WIDAL TEST TECHNIQUES WITH STOOL CULTURE IN THE DIAGNOSIS OF TYPHOID FEVER AT THE DSCHANG DISTRICT HOSPITAL, WEST CAMEROON

Objective: This study is aimed to compare the performance of two Widal test techniques with stool culture in the diagnosis of typhoid fever. Methods: A cross-sectional study was performed at the Dschang District Hospital in patients clinically suspected to have typhoid fever, whose stool was collected for stool culture. Furthermore, venous blood was collected and the serum was tested by both Widal slide agglutination test and Widal tube titration test. Results: The results showed that out of 750 participants include in the study, 325 (43.33%) were positive for Widal slide agglutination test, 174 (23.20%) for Widal tube titration test, and 159 (21.20%) for stool culture. The sensitivity, specificity, positive predictive value, and negative predictive value of Widal slide agglutination test with respect to stool culture were 97.48%, 71.23%, 47.69%, and 99.22%, respectively, but 100%, 97.46%, 91.37%, and 100% for the Widal tube titration test. With the stool culture, Widal slide agglutination test had a moderate agreement (kappa = 0.47), but Widal tube titration test had an absolute agreement (kappa = 0.94). Conclusion: Widal tube titration test should be used in place of Widal slide agglutination test in the diagnosis of typhoid fever in the case of limited access to stool culture test

Evaluation of metabolic syndrome in undergraduate students at the University of Dschang

Metabolic syndrome (MetS) is a cluster of risk factors for cardiovascular diseases (CVD), such as obesity, dyslipidemia, high blood pressure, and high blood glucose; it increases morbidity and mortality of CVD. MetS affects both adults and youths, leading to an impaired quality of life and a lowering of life expectancy. This study aimed to assess various aspects of metabolic syndrome, in undergraduate students at the University of Dschang. A questionnaire was distributed to 307 students of both sex; 203 meeting inclusion criteria were selected for anthropometric and blood pressure measurements followed by blood sample collection, for the dosage of biochemical markers (blood glucose, total cholesterol, LDL cholesterol, HDL cholesterol, triglyceridemia, and C-reactive protein). Results indicate that the prevalence of metabolic syndrome within the study population was 11.33 %. It has a significant predominance among obese and overweight patients (P˂0.05), compared to normal ones. Elevated blood pressure (OR= 23.4) and low HDL cholesterol levels (OR= 20.4) appeared to be the most determinant components of metabolic syndrome in the study population. We found an increase of metabolic syndrome prevalence with frequent consumption (3 to 4 times per week) of ‘‘Koki’’ (P=0.023), ‘‘Achu’’ (P=0.01), ‘’Corn couscous’’ (P=0.012), Salads (P=0.031), ‘‘Ndolè’’ (P=0.039) and pork (P=0.04). On the contrary, the prevalence of metabolic syndrome decreases significantly, with frequent consumption of green vegetables (P=0.016). Metabolic syndrome is present in undergraduate students of the University of Dschang, as a consequence of excess fat storage. Its main features are elevated blood pressure and low HDL-cholesterol level.Keywords: Obesity; Metabolic syndrome; cardiovascular risk factor; students; University of Dschan

Clinical Manifestations and Changes of Haematological Markers among Active People Living in Polluted City: The Case of Douala, Cameroon

International audienceUrban air pollution, despite its dangerous health impact, is poorly studied in sub-Saharan Africa (sSA). Epidemiological data on this silent killer are almost non-existent for cities of Cameroon, which seems to be one of the sSA countries where populations are highly exposed to air pollutants. Objective: The present study was conducted in Douala city, and aimed at determining the association of urban air quality degradation with respiratory and systemic health in active populations exposed to air pollutants on a daily basis. Methods: A cross-sectional study was conducted from 2017 to 2019 in 1182 active people consisting of motorbikes drivers (MD), outdoor urban workers (UW), and fuel station sellers (FSS). A standardized questionnaire was used to document participants' data. One hundred and twenty-six (126) motorbike drivers were selected to evaluate the relationship between haematological (white blood cells, platelets) and inflammatory (C-reactive protein-CRP) biomarkers, and air pollution; compared with those of a sixty-five (65) motorbike drivers' control group enrolled in Dschang, another town situated at about 216.3 km from Douala. Results: Among those recruited in urban Douala, some respiratory disorders such as running nostrils, colds, common fever, sore throats, dry cough, wheezing, chest pain, shortness of breath and systemic symptoms such as headaches, eye irritation, conjunctivitis, watery eyes and general tiredness were very common among MD, UW, and FSS. Regarding biological data, blood monocytes, lymphocytes and CRP were found to be significantly increased among selected MD in Douala, compared to control groups in Dschang. Conversely, a more significant decrease in blood neutrophil level was observed among MD in Douala than control groups in Dschang. These changes of haematological markers were significantly associated with place of residence, site of activity, and daily duration. Conclusion: Our results suggest the risk of suffering from respiratory impairments and systemic symptoms with exposure to urban air pollution among active people working near highways in Douala

Evaluation of the Effects of Agro Pesticides Use on Liver and Kidney Function in Farmers from Buea, Cameroon

Agro pesticides are increasingly used worldwide to increase crop production. However, health hazards resulting from human exposure to these chemicals, especially from agricultural areas of developing countries have been a growing concern. The objective of this study was to evaluate the impact of occupational exposure to agro pesticides on the health of farmers in the Buea subdivision, which is one of the major agrarian areas in Cameroon. The study was transversal and involved 90 participants including 58 farmers using pesticides and a reference population of 32 men not involved in occupational use of agro pesticides. The participants were interviewed on agro pesticide use and their health status. Thereafter, blood samples were collected from the participants and used for the assessment of biochemical markers of the liver (alanine aminotransferase and aspartate aminotransferase) and the kidney (creatinine and uric acid) function. Results revealed that farmers frequently used insecticides, fungicides, and herbicides in their farming activities. Farmers reported several acute health symptoms related to pesticides use with the common ones being skin rash, eye irritation, and face burn. When compared to the reference population, the farmers showed significantly elevated (p<0.01) alanine aminotransferase activity. However, other parameters investigated were not affected significantly. These results suggested that farmers were exposed to 3 different classes of agro pesticides, which induced eye and skin affections. Pesticides exposure resulted in alterations of the liver function hence the increased serum alanine aminotransferase activity. Therefore, there is a need to sensitize the farmers on toxicity and liver alteration potential of agro pesticides and the importance of appropriate protective equipment that may minimize exposure
