Scaling up of diagnostic capacity is needed to mitigate the global pandemic of SARS-CoV2. However, there are challenges including shortage of sample collection swabs and transport medium. Saliva has been recommended as a simple, low-cost, non-invasive option. However, data from different populations and settings are limited. Here, we showed that saliva could be a good alternative sample to diagnose COVID-19 patients. Pair of NPS-saliva samples was collected from 152 symptomatic; confirmed COVID-19 patients, and compared their positivity rate, viral load, and duration of viral shedding. From 152 patients, 80 (52.63%) tested positive and 72 (47.37%) were negative for SARSA-CoV2 in NPS sample. In saliva, 129 (92.14%) were tested positive and 11 (7.86%) were negative on the day of admission to hospital. The overall percent agreement of RT-PCR result of Saliva to NPS was 70% (196/280). A comparison of viral load from 72 NPS-saliva pair samples on day of admission shows saliva contains significantly higher viral load (P < 0.001). In conclusion, saliva has higher yield in detecting SARS-CoV2, and COVID-19 patients show higher viral load and prolonged period of viral shedding in saliva. Therefore, we recommend saliva as a better alternative sample to NPS to diagnose COVID-19 patients.
BackgroundThe emergence of highly active antiretroviral therapy (HAART) has dramatically improved quality of life in prolonging survival of human immunodeficiency virus (HIV)-infected patients on treatment in developed as well as developing countries. However, the main shortcoming of HAART in long-term use is its potential to cause liver and kidney derangements that may be life threatening. The drugs are actively accumulated in the proximal renal tubule resulting in functional disturbance with mitochondrial injury being one of the most important targets recognized. Therefore, the aim of this study was to assess the adverse effects of HAART on kidney and liver functions among HIV-infected patients presenting to the University of Gondar Hospital, Ethiopia.Materials and methodsAn institution-based retrospective study was conducted from 2010 to 2015 on a subset of HIV-infected patients. Data were collected from the registration book of the University of Gondar Hospital antiretroviral clinic laboratory after checking the completeness of age, gender, creatinine, blood urea nitrogen, and alanine aminotransferase level. Data were entered and analyzed using SPSS version 20. Descriptive statistics, chi-square test, one-way analysis of variance, and logistic regression were done to determine associations. A P-value <0.05 was considered statistically significant.ResultsA total of 275 study subjects were included in the study. Of these, 62.2% were females, and the overall prevalence of chronic kidney disease (CKD) before and after treatment was 3.6% and 11.7%, respectively. A majority of the CKD patients were in stage 3 for patients after treatment. The overall prevalence of hepatotoxicity was 6.5% and 16.7% before and after treatment, respectively. A majority of the patients developed Grade 2 hepatotoxicity 66.7% and 65.2% before and after treatment, respectively. Binary and multiple logistic regression analysis indicated that the female gender was a risk factor for CKD.ConclusionThe prevalence of nephrotoxicity and hepatotoxicity were high among patients who took HAART. Stage 3 nephrotoxicity and Grade 2 hepatotoxicity had the highest incidences of the total toxicities, and the female gender was a risk factor for nephrotoxicity. Further prospective studies are recommended to determine the effect of HAART and contributing factors.
BackgroundVitamin A deficiency (VAD) is known to be a major public health problem among women of reproductive age in South East Asia and Africa. In Ethiopia, there are no studies conducted on serum vitamin A status of HIV-infected pregnant women. Therefore, the present study was aimed at determining the level of serum vitamin A and VAD among pregnant women with and without HIV infection in tropical settings of Northwest Ethiopia.MethodsIn this cross-sectional study, blood samples were collected from 423 pregnant women and from 55 healthy volunteers who visited the University of Gondar Hospital. Serum concentration of vitamin A was measured by high performance liquid chromatography.ResultsAfter controlling for total serum protein, albumin and demographic variables, the mean ± SD serum vitamin A in HIV seropositive pregnant women (0.96 ± 0.42 μmol/L) was significantly lower than that in pregnant women without HIV infection (1.10 ± 0.45 μmol/L, P < 0.05). Likewise, the level of serum vitamin A in HIV seropositive non-pregnant women (0.74 ± 0.39) was significantly lower than that in HIV negative non-pregnant women (1.18 ± 0.59 μmol/L, P < 0.004). VAD (serum retinol < 0.7 μmol/L) was observed in 18.4% and 17.7% of HIV infected and uninfected pregnant women, respectively. Forty six percent of non-pregnant women with HIV infection had VAD while only 28% controls were deficient for vitamin A (P = 0.002).ConclusionThe present study shows that VAD is a major public health problem among pregnant women in the tropical settings of Northwest Ethiopia. Considering the possible implications of VAD during pregnancy, we recommend multivitamin (which has a lower level of vitamin A) supplementation in the care and management of pregnant women with or without HIV infection.
Background Cervical cancer is a major public health problem. In the world, cervical cancer is the fourth most common cancer among women and it is one of the leading causes of cancer mortality in females. It is the second most common women cancer in Ethiopia with almost 6300 new cases and 4884 deaths annually. Despite the high burden of new cases and deaths, there is a scarcity of data on knowledge, attitude and practices (KAP) towards cervical cancer screening among female university students in Ethiopia particularly in the study area. Therefore, the present study was aimed to assess the KAP of undergraduate female students towards cervical cancer screening. Methods An institution based cross-sectional study was conducted in April 2018 at the University of Gondar, College of Medicine and Health Sciences undergraduate female students. Pretested, self-administered questionnaire was used for data collection. Four hundred and three female students were recruited by a simple random sampling method and the data were entered and analyzed using SPSS version 20 statistical packages. Descriptive data analysis was used to report the results. Results More than half of the respondents (59.3.3%) had good knowledge, whereas nearly 67.7% of the respondents had favorable attitude towards cervical cancer. However, less than 1% of the respondents had been screened for cervical cancer. Conclusion Although undergraduate female students had apparently good knowledge and favorable attitude, their practices on cervical cancer screening were quite low. Therefore, the health sectors and the gender streaming office of the university mobilize students to strengthen the uptake the cervical cancer screening practice.
