RESUMEN

HIV self-testing (HIVST) holds promise for accessing hard-to-reach populations by overcoming sociocultural and structural barriers to awareness of HIV status. This phenomenological qualitative study explored the experiences and perspectives of married men in Kano, northern Nigeria, regarding HIV testing and counseling (HTC) and HIVST. Twenty married men from diverse socioeconomic backgrounds participated in in-depth interviews conducted in the local language. Thematic analysis was employed to analyze the data, yielding key themes related to prior test experiences, knowledge of self-testing, and perceived ease of use, in addition to motivation for self-testing and concerns about reliability and counseling support. The findings shed light on the impact of facility-based HIV testing experiences on the perspectives of participants. Concerns related to delays, overcrowding, discomfort, fear, and unsupportive attitudes from healthcare providers influenced their perceptions. Among persons with previous self-testing experience, initial uneasiness was overcome with repeated use, highlighting the ease of use associated with HIVST. Motivations for self-testing included privacy, convenience, personal empowerment, improved infection detection, and efficiency. Concerns were raised regarding the reliability of self-testing results compared to hospital-based testing, and the absence of counseling support during self-testing. Our findings underscore the need to address infrastructural limitations, enhance counseling support, and promote awareness and knowledge of HIVST.

RESUMEN

Introduction: Telemedicine practice experiences during the COVID-19 pandemic have not been well documented in resource-constrained settings, such as Nigeria. We set out to assess knowledge, attitude, and factors associated with telemedicine practice during the COVID-19 lockdown, as well as physician experiences in Kano, Nigeria. Methods: We employed a mixed-methods approach, utilizing structured questionnaires administered to 246 physicians, followed by in-depth interviews with a purposive subsample of 20 individuals. The data were analyzed using logistic regression and the framework approach. Results: Overall, 65.0% of the respondents demonstrated moderate to good knowledge of telemedicine. Before COVID, only 47.6% (n = 117) reported practicing telemedicine, compared with 77.2% (n = 190) during the COVID lockdown (p < 0.05). Factors associated with telemedicine practice included having at least 5 years of work experience, working in pediatrics, undergoing senior residency training, receiving formal telemedicine training, possessing good knowledge of telemedicine, and having a positive attitude toward it. The odds of engaging in telemedicine practice were four times higher (adjusted odds ratio = 4.10, 95% confidence interval: 1.79-9.40) for those who practiced it before the pandemic. Challenges identified included knowledge and skill gaps, slow internet connectivity, unstable electricity, and inadequate equipment. Conclusion: To enhance telemedicine practice in resource-limited settings, it is important to focus on strengthening information and communication infrastructure, providing comprehensive clinician training, implementing careful patient selection processes, and improving practice guidelines.

RESUMEN

INTRODUCTION: Envenoming by Echis spp. (carpet or saw-scaled vipers) causes haemorrhage and coagulopathy and represents a significant proportion of snakebites in the savannah regions of West Africa. Early diagnosis of envenoming is crucial in the management of these patients and there is limited evidence on the utility of the 20-minute whole blood clotting test (20WBCT) in diagnosing venom-induced consumptive coagulopathy (VICC) following envenoming by Echis ocellatus. METHODS: A prospective observational cohort study was conducted at the Kaltungo General Hospital in North-eastern Nigeria from September 2019 to September 2021. Standardised 20WBCTs were conducted by trained hospital staff and citrated plasma samples were collected at numerous timepoints. Prothrombin time (PT) and international normalised ratio (INR) were determined using a semi-automated analyser and INR values were calculated using international sensitivity indices (ISI). The sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and likelihood ratios of the 20WBCT compared to an INR ≥ 1.4 were calculated, alongside 95% confidence intervals. RESULTS: We enrolled 121 patients into our study, with a median age of 26 (18.0-35.0) years and a male predominance (75.2%). The 20WBCT was positive (abnormal) in 101 out of 121 patients at timepoint 0h, of which 95 had an INR ≥ 1.4, giving a sensitivity of 87.2% (95%CI 79.4-92.8). Among patients with a negative 20WBCT (normal), six had an INR < 1.4 giving a specificity of 50% (95%CI 21.1-78.9). The positive and negative likelihood ratios were 1.7 (95%CI 1.6-1.9) and 0.3 (95%CI 0.1-0.4) respectively. CONCLUSION: The 20WBCT is a simple, cheap, and easily accessible bedside test with a high sensitivity for the detection of patients with venom induced consumptive coagulopathy (VICC) following envenoming by E. ocellatus, although false positives do occur. Repeated 20WBCTs can identify patients with new, persistent, and rebound coagulopathy.

RESUMEN

Background and Objective: The COVID-19 pandemic response overwhelmed health systems, disrupting other services, including maternal health services. The disruptive effects on the utilization of maternal health services in low-resource settings, including Nigeria have not been well documented. We assessed maternal health service utilization, predictors, and childbirth experiences amidst COVID-19 restrictions in a rural community of Kumbotso, Kano State, in northern Nigeria. Methods: Using an explanatory mixed methods design, 389 mothers were surveyed in January 2022 using validated interviewer-administered questionnaires, followed by in-depth interviews with a sub-sample (n=20). Data were analyzed using logistic regression models and the framework approach. Results: Less than one-half (n=165, 42.4%) of women utilized maternal health services during the period of COVID-19 restrictions compared with nearly two-thirds (n=237, 65.8%) prior to the period (p<0.05). Non-utilization was mainly due to fear of contracting COVID-19 (n=122, 54.5%), clinic overcrowding (n=43, 19.2%), transportation challenges (n=34, 15.2%), and harassment by security personnel (n=24, 10.7%). The utilization of maternal health services was associated with participant's post-secondary education (aOR=2.06, 95% CI:1.14- 11.40) (p=0.02), and employment type (civil service, aOR=4.60, 95% CI: 1.17-19.74) (p<0.001), business aOR=1.94, 95% CI:1.19- 4.12) (p=0.032) and trading aOR=1.62, 95% CI:1.19-2.94) (p=0.04)). Women with higher household monthly income (≥ N30,000, equivalent to 60 US Dollars) (aOR=1.53, 95% CI:1.13-2.65) (p=0.037), who adhered to COVID-19 preventive measures and utilized maternal health services before the COVID-19 pandemic were more likely to utilize those services during the COVID-19 restrictions. In contrast, mothers of higher parity (≥5 births) were less likely to use maternal health services during the lockdown (aOR=0.30, 95% CI:0.10-0.86) (p=0.03). Utilization of maternal services was also associated with partner education and employment type. Conclusion and Global Health Implications: The utilization of maternal health services declined during the COVID-19 restrictions. Utilization was hindered by fear of contracting COVID-19, transport challenges, and harassment by security personnel. Maternal and partner characteristics, adherence to COVID-19 preventive measures, and pre-COVID maternity service utilization influenced attendance. There is a need to build resilient health systems and contingent alternative service delivery models for future pandemics.

RESUMEN

Polymorphism of the prion protein gene (PRNP) gene determines an animal's susceptibility to scrapie. Three polymorphisms at codons 136, 154, and 171 have been linked to classical scrapie susceptibility, although many variants of PRNP have been reported. However, no study has investigated scrapie susceptibility in Nigerian sheep from the drier agro-climate zones. In this study, we aimed to identify PRNP polymorphism in nucleotide sequences of 126 Nigerian sheep by comparing them with public available studies on scrapie-affected sheep. Further, we deployed Polyphen-2, PROVEAN, and AMYCO analyses to determine the structure changes produced by the non-synonymous SNPs. Nineteen (19) SNPs were found in Nigerian sheep with 14 being non-synonymous. Interestingly, one novel SNP (T718C) was identified. There was a significant difference (P < 0.05) in the allele frequencies of PRNP codon 154 between sheep in Italy and Nigeria. Based on the prediction by Polyphen-2, R154H was probably damaging while H171Q was benign. Contrarily, all SNPs were neutral via PROVEAN analysis while two haplotypes (HYKK and HDKK) had similar amyloid propensity of PRNP with resistance haplotype in Nigerian sheep. Our study provides valuable information that could be possibly adopted in programs targeted at breeding for scrapie resistance in sheep from tropical regions.

RESUMEN

The 20 minutes Whole Blood Clotting Test (20WBCT) was evaluated in 1541 snakebite patients at 3 hospitals in Nigeria. It was useful in detection, monitoring, guiding antivenom therapy and prognostication of coagulopathy, with initial sensitivity of 84.7% (95%CI:82.7-86.5%) and specificity of 64.3% (95%CI:50.4-76.7%) compared to clinical envenoming. It led to correct decisions regarding administration or withholding antivenom in 97.93% of patients. The proportion of carpet viper (Echis romani) envenomed patients who restored clotting rose steadily following effective antivenom therapy. Patients with positive 20WBCT had severer envenoming, required more blood transfusion, had longer hospital stay and derived higher antivenom protection against death from carpet viper. However, there was no association between positive 20WBCT and fatality or complications.

RESUMEN

Scrapie is a fatal prion protein disease stiffly associated with single nucleotide polymorphism (SNPs) of the prion protein gene (PRNP). The prevalence of this deadly disease has been reported in small ruminants, including goats. The Nigerian goats are hardy, trypano-tolerant, and contribute to the protein intake of the increasing population. Although scrapie has been reported in Nigerian goats, there is no study on the polymorphism of the PRNP gene. Herein, we evaluated the genetic and allele distributions of PRNP polymorphism in 132 Nigerian goats and compared them with publicly available studies on scrapie-affected goats. We utilized Polyphen-2, PROVEAN and AMYCO programs to examine structural variations produced by the non-synonymous SNPs. Our study revealed 29 SNPs in Nigerian goats, of which 14 were non-synonymous, and 23 were novel. There were significant differences (P < 0.001) in the allele frequencies of PRNP codons 139, 146, 154 and 193 in Nigerian goats compared with scrapie-affected goats, except for Northern Italian goats at codon 154. Based on the prediction by Polyphen-2, R139S and N146S were 'benign', R154H was 'probably damaging', and T193I was 'possibly damaging'. In contrast, PROVEAN predicted 'neutral' for all non-synonymous SNPs, while AMYCO showed a similar amyloid propensity of PRNP for resistant haplotype and two haplotypes of Nigerian goats. Our study is the first to investigate the polymorphism of scrapie-related genes in Nigerian goats.

RESUMEN

This study examined the support for vaccine mandates and uptake among clinical and non-clinical staff at a tertiary hospital in northern Nigeria, focusing on variation of survey responses based on job position, socio-demographic characteristics, and perceived risk of infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Using an explanatory, sequential, mixed-methods design and deploying a pragmatic paradigm, 370 healthcare workers were administered structured questionnaires. This was followed by in-depth interviews with a sub-sample of respondents to further clarify the responses regarding support for the coronavirus disease 2019 (COVID-19) vaccine mandate. Findings demonstrated that less than one-half of respondents supported the COVID-19 mandate, and only one in three had received the recommended COVID-19 vaccine doses. Support for the vaccine mandate and vaccine uptake were predicted by profession, work experience, number of children, health status, and risk perception. Support for the vaccine mandate was ascribed to ethical and professional duty, whereas opposition was associated with respect for autonomy and human rights. This study documents the need to enhance support for vaccine mandates and uptake among healthcare workers through sustainable strategies, as Nigeria's healthcare workers are considered a source of trust and role models for the rest of society.

RESUMEN

BACKGROUND: People living with HIV (PLHIV) are at increased risk of COVID-19 acquisition, severe disease, and poor outcomes. Yet, little is known about COVID-19 vaccine hesitancy among PLHIV in high HIV burden countries, such as Nigeria. OBJECTIVE: This study aims to assess the acceptability of the COVID-19 vaccine and identify predictors and reasons for vaccine hesitancy among patients living with HIV and attending a tertiary hospital in Kano, northern Nigeria. METHODS: Using a mixed-methods design, structured questionnaires were administered to a clinic- based sample of patients living with HIV (n = 344), followed by 20 in-depth interviews with a sub-sample. Logistic regression and the framework approach were used to analyze the data. RESULTS: Less than half (46.2 %, n = 159) of the respondents were willing to take the COVID-19 vaccine. Vaccine acceptance was higher among non-Muslim PLHIV (Adjusted Odds Ratio (aOR) = 1.26, 95 % Confidence Interval (95 % CI): 1.10-4.00), persons with high-risk perception (aOR = 2.43, 95 % CI:1.18-5.00), those who were not worried about infertility-related rumors (aOR = 13.54, 95 % CI:7.07-25.94) and persons who perceived antiretroviral drugs are protective against COVID-19 (aOR = 2.76, 95 % CI: 1.48-5.14). In contrast, vaccine acceptance was lower among persons who were not concerned about the potential effects of COVID-19-HIV co-infection (aOR = 0.20, 95 % CI:0.10-0.39). The most common reasons for vaccine hesitancy included doubts about the existence of COVID-19, low-risk perception, anxiety about antiretroviral treatmentvaccine interactions, safety concerns, and infertility-related rumors. CONCLUSION: Covid-19 vaccine acceptance was low among PLHIV. COVID-19 vaccine acceptance was associated with respondents' faith, risk perception, perception of the protective effects of antiretroviral treatment, concerns about COVID-19-HIV co-infection, and infertility-related rumors. Vaccination counseling should be integrated into HIV treatment services to improve COVID-19 vaccine uptake among PLHIV in Kano, Nigeria and similar settings.

RESUMEN

We assessed the acceptability of COVID-19 vaccine, predictors, and reasons for vaccine hesitancy among clinical and non-clinical staff at a tertiary hospital in Kano, northern Nigeria.Using a mixed-methods design, structured questionnaires were administered to 284 hospital staff, followed by 20 in-depth interviews with a purposive sub-sample. Logistic regression and the framework approach were used to analyze the data.Only 24.3% (n = 69) of the respondents were willing to accept the COVID-19 vaccine. Acceptance was lower among females (Adjusted Odds Ratio (aOR) = 0.37, 95% Confidence Interval (95%CI): 0.18-0.77 (male vs. female), nurses/midwives (aOR = 0.41, 95%CI:0.13-0.60, physicians vs. nurses/midwives), persons not tested for COVID-19 (aOR = 0.32, 95%CI 0.13-0.79) (no vs. yes) and those who perceived themselves to be at low risk of COVID-19 (aOR = 0.47, 95%CI,0.21-0.89, low vs. high). In contrast, vaccine acceptance was higher among more experienced workers (aOR = 2.28, 95%CI:1.16-8.55, ≥10 vs. <5 years). Vaccine acceptance was also higher among persons who did not worry about vaccine efficacy (aOR = 2.35, 95%CI:1.18-6.54, no vs. yes), or about vaccine safety (aOR = 1.76, 95%CI: 1.16-5.09, no vs. yes), side effects (aOR = 1.85, 95%CI:1.17-5.04, no vs. yes), or rumors (aOR = 2.55, 95%CI:1.25-5.20, no vs. yes). The top four reasons for vaccine hesitancy included distrust, inadequate information, fear of long-term effects, and infertility-related rumors.Concerted efforts are required to build COVID-19 vaccine confidence among health workers in Kano, Nigeria.Our findings can help guide implementation of COVID-19 vaccination in similar settings.

RESUMEN

BACKGROUND: Overconsumption of energy drinks (EDs) is a global public health concern because of its potential health consequence. OBJECTIVES: This study aimed to determine the prevalence and factors associated with ED consumption amongst undergraduate students in Kano, Northwest Nigeria. METHODOLOGY: A descriptive cross-sectional study design was used to study 381 undergraduate students, selected using a two-stage sampling technique. Data were collected using interviewer-administered questionnaires and analysed using SPSS version 22.0 with P ≤ 0.05 considered to be statistically significant. RESULTS: : A total of 381 students were studied. The mean ± standard deviation age of the students was 23.1 ± 3.6 years with male-to-female distribution of about 1:1. Period prevalence of 67.0% within the last 30 days and point prevalence of 23.9% were found. The commonly used ED was Power Horse 44.6%. Up to 59.6% consumed EDs to boost their physical and mental capacity. Odds of ever-consuming EDs were lower in female undergraduates (adjusted odds ratio [aOR]: 0.5, 95% confidence interval [CI]: 0.3-0.7) and higher in Hausa/Fulani ethnic group (aOR: 1.7, 95% CI: 1.04-2.7). Amongst those who were currently consuming EDs, being 24 years or less (aOR: 1.9, 95% CI: 1.04-3.4) and coming from the Hausa/Fulani tribe (aOR: 2.5, 95% CI: 1.4-4.4) were associated with increased consumption. Male undergraduates (aOR: 0.2, 95% CI: 0.1-0.4) and students who were residing on campus were less likely to be current consumers of EDs (aOR: 0.5, 95% CI: 0.3-0.9). CONCLUSION: Consumption of EDs is increasing amongst students and therefore relevant government agencies should ensure regulated advertisement and consumption to avert the health consequences.

RESUMEN

Vaccination is a critical tool in the global response to the COVID-19 pandemic. Yet, COVID-19 vaccine hesitancy has not been well explored in parts of Nigeria. We assessed the predictors of acceptability of the COVID-19 vaccine and identified reasons for vaccine hesitancy among adults in urban Kano, northern Nigeria. Using a mixed-methods design, we administered structured questionnaires to a cross-section of adults (n = 446), complemented with 20 in-depth interviews. Binary logistic regression and the framework approach were used to analyze the data. About one-half (51.1%, n = 228) of the respondents were willing to take the COVID-19 vaccine. Vaccine acceptance was higher among older respondents (≥30 years) (adjusted Odds Ratio (aOR) = 1.76, 95% Confidence Interval (CI): 1.14-2.99 (≥30 vs. <30), higher-income earners (≥30,000 Naira) (aOR = 2.06, 95%CI:1.12-3.80, ≥30,000 vs. <30,000), and those with a history of a chronic medical disorder (aOR = 1.90, 95%CI:1.06-3.72). Vaccine acceptance was also higher in persons with high risk perception (aOR = 1.61, 95%CI:1.13-2.81, high vs. low), those who were unconcerned about vaccine safety (aOR = 1.71, 95%CI:1.13-3.55), and those who were not worried about efficacy (aOR = 2.02, 95%CI:1.14-4.11) and infertility-related rumors (aOR = 1.98, 95%CI:1.24-3.18). Themes revealed doubts about the existence of COVID-19, mistrust for authorities, and popular credence to rumors and conspiracy theories. In conclusion, COVID-19 vaccine acceptance was sub-optimal and influenced by respondent's age, income, co-morbidities, risk perception, and concerns about vaccine safety, efficacy, and rumors. Context-specific, evidence-based risk communication strategies and trust-building measures could boost vaccine confidence in similar settings.

RESUMEN

BACKGROUND: In line with global standards and progress made in Prevention of Motherto- Child Transmission (PMTCT), an assessment of the outcome of Early Infant Diagnosis in northern Nigeria is necessary to evaluate progress towards zero Human immunodeficiency Virus (HIV) infection among children. OBJECTIVES: This study assessed the infection rate and risk factors for mother-to-child HIV transmission among HIV-exposed children in Kano, northwest Nigeria. METHODS: Using a retrospective cohort design, pregnant HIV-positive women and their exposed infants were recruited over a period of six years (2010 to 2016). Participants were enrolled during pregnancy or at delivery in the PMTCT clinic of a tertiary health facility in Kano, Nigeria. The main outcomes for the study were Early infant diagnosis positivity for HIV at 6 weeks and risk factors for positivity. RESULTS: Of the 1,514 infants studied, early infant diagnosis was positive for HIV among 13 infants (0.86%). Infants whose mothers did not have antiretroviral therapy (adjusted Prevalence Ratio aPR = 2.58, 95%CI (1.85- 3.57)), who had mixed feeding (aPR = 12.06, 95%CI (9.86- 14.70)), and those not on antiretroviral prophylaxis (aPR = 20.39, 95%CI (16.04- 25.71)) were more likely to be infected with HIV. HIV-exposed infants on nevirapine and zidovudine prophylaxis were 95% and 74%, respectively, less likely to be infected with HIV. CONCLUSION: HIV infection rate remains high among HIV-exposed infants whose mothers did not receive PMTCT services. Scaling up proven interventions of early commencement of antiretroviral treatment for mothers, adherence to antiretroviral prophylaxis, and avoidance of mixed feeding among HIV-exposed infants would protect future generations from HIV infection.

RESUMEN

The parasite Trypanosoma brucei is the main cause of the sleeping sickness threatening millions of populations in many African countries. The parasitic infection is currently managed by some synthetic medications, most of them suffer limited activity spectrum and/or serious adverse effects. Some studies have pointed out the promising therapeutic potential of the plant extracts rich in polyphenols to curb down parasitic infections caused by T. brucei and other trypanosomes. In this work, the main components dominating Eugenia uniflora and Syzygium samarangense plant extracts were virtually screened, through docking, as inhibitors of seven T. brucei enzymes validated as potential drug targets. The in vitro and in vivo anti-T. brucei activities of the extracts in two treatment doses were evaluated. Moreover, the extract effects on the packed cell volume level, liver, and kidney functions were assessed. Five compounds showed strong docking and minimal binding energy to five target enzymes simultaneously and three other compounds were able to bind strongly to at least four of the target enzymes. These compounds represent lead hits to develop novel trypanocidal agents of natural origin. Both extracts showed moderate in vitro anti-trypanosomal activity. Infected animal groups treated over 5 days with the studied extracts showed an appreciable in vivo anti-trypanosomal activity and ameliorated in a dose dependent manner the anaemia, liver, and kidney damages induced by the infection. In conclusion, Eugenia uniflora and Syzygium samarangense could serve as appealing sources to treat trypanosomes infections.

RESUMEN

CONTEXT: Sexual abuse of young female hawkers is a subject of public health importance with resultant long-lasting physical and mental consequences. AIMS: This study assessed the prevalence, pattern and predictors of sexual abuse among female hawkers in Kano State, Nigeria. SETTINGS AND DESIGN: Using a descriptive cross-sectional design and two-stage sampling technique, female hawkers in Kano metropolis were studied. SUBJECTS AND METHODS: An adapted and pre-tested semi-structured interviewer-administered questionnaire was used to obtain information from 236 female hawkers. Data were analysed with SPSS Statistics, version 24.0 software. Prevalence and pattern of sexual abuse was determined and adjusted odds ratios of predictors derived from binary logistic regression models. RESULTS: The prevalence of sexual abuse was 68.6%. Forms of sexual abuse reported included verbal abuse (38.1%), inappropriate touch (64.0%) and rape (25.8%). Predictors of sexual abuse included respondents' age (adjusted odds ratio [aOR] = 10.65, 95% confidence interval [CI] [2.92-38.84]), ethnicity (aOR = 4.26, 95% CI [1.30-14.00]), highest educational attainment (aOR = 0.38, 95% CI [0.15-0.99]), residence with parent (s) (aOR = 0.07, 95%CI [0.01-0.54]) and parents being alive (aOR = 6.79, 95%CI [1.41-32.62]). CONCLUSIONS: Sexual abuse is prevalent among female hawkers and the forms experienced ranged from verbal abuse to inappropriate touch and rape. Interventions that delay age at the commencement of hawking, ensure the education of the girl child and support parental care could foster more matured and smart female hawkers who can avoid sexual abuse.

RESUMEN

OBJECTIVES: We aimed to determine the concordance between own and perceived partner fertility intentions and identify predictors of contraceptive use among couples receiving antiretroviral therapy in Kano, Nigeria. METHODS: A structured, validated questionnaire was used to interview 399 married men and women receiving antiretroviral therapy. Adjusted odds ratios for predictors of contraceptive use were derived from multivariate logistic regression models. RESULTS: Most couples (68.9%) had concordant fertility intentions. Only 10.0% of couples had discordant fertility intentions. Among 232 couples (58.1%) at least one partner used contraception. Male condoms were used by 45.9% of couples (n = 183). Female methods were used by 175 couples (43.9%). Contraceptive use was significantly higher in participants who were older (≥30 years), better educated (secondary or post-secondary), had a higher monthly income (NGN ≥30,000), longer marriage duration (≥5 years), at least one living child, >1 year of antiretroviral treatment, and who were living with a serodiscordant partner and in circumstances where the decision on contraception was made by the female partner or jointly by both partners (all p < 0.05). Contraceptive use was significantly lower in participants who had not been sexually active in the last 6 months, where both partners wanted more children, and in situations lacking spousal communication about family planning (all p < 0.05). CONCLUSION: One in 10 couples had discordant fertility intentions. Contraceptive use was suboptimal and was predicted by age, education, income, length of marriage, number of children, duration of antiretroviral therapy, partner's serostatus, sexual activity, fertility intention, spousal communication and the contraceptive decision-maker. Our findings highlight the need for spousal communication, joint contraceptive decision making and the integration of reproductive health services with antiretroviral therapy services.

RESUMEN

Previous studies have suggested a possible connection between insulin resistance and chronic hyperglycemia with membrane sialic acid content. In this study, the effects of high (20% ad libitum) fructose and glucose feeding on the sialic acid levels of some organs were investigated in rats. The blood glucose levels of the high fructose- and glucose-fed rats were consistently and significantly (P < 0.05) higher than the normal control throughout the experiment. Free serum sialic acid and total hepatic sialic acid levels were elevated in the high fructose- and glucose-fed rats compared to normal control, but only the data for the high glucose-fed group were significantly (P < 0.05) different from the normal control. Conversely, a significant (P < 0.05) decrease in the pancreatic sialic acid level was observed in high glucose-fed group compared to normal control. Also, the high fructose-fed rats had lower, but insignificant (P > 0.05), pancreatic sialic acid level than the normal control. On the other hand, high fructose and glucose feeding did not significantly (P > 0.05) affect the sialic acid levels of the skeletal muscle and heart, though a tendency to increase the sialic acid level was evident in the heart. In the kidney, the sialic acid level was significantly (P < 0.05) increased in both high fructose- and glucose-fed groups. It was concluded that the liver and kidney tend to stimulate sialic acid synthesis, while the pancreas downregulate sialic acids synthesis and/or promote sialic acid release from glycoconjugates. Also, these organs may contribute to high-serum sialic acid level observed during diabetes.
