Factors Associated with the Outcome of 2023 Diphtheria Outbreak in Jigawa State, Nigeria: A Retrospective Review of the Surveillance Data.

OBJECTIVE: The objective of this study was to identify the factors associated with the outcome of the 2023 diphtheria outbreak in Jigawa State, Nigeria. METHODS: A descriptive cross-sectional study was conducted amongst all line-listed diphtheria cases reported from Jigawa State, Nigeria, using the 2023 Integrated Disease and Surveillance Response line list of cases that met the World Health Organization case definition of diphtheria. A total of 245 line-listed cases from January 2023 to December 2023 met the criteria for inclusion in the study. Data were analysed using IBM SPSS version 22.0 with a P value set at ≤5%. Binary logistic regression was used to identify the independent predictors of the outcome of the 2023 outbreak. RESULTS: The maximum age of the line-listed cases was 39 years, and the minimum was 1 year with a median of 8 (interquartile range = 5-8) years. More than two-thirds (68.2%) of the cases were ≥5 years of age. More than one-third of the cases (39.6%) were from the northeast senatorial zone of the state. Out of the total 245 cases, 14 died of the disease representing a case fatality rate of 6%, and an attack rate of 3.4 per 100,000 populations. The majority of the cases (95.5%) had fever, cough (81.2%), pharyngitis (86.9%), tonsillitis (96.7%) and laryngitis (82.0%). More diphtheria-related mortalities were recorded amongst cases <5 years of age (7.7%), female cases (5.9%), rural residence (7.7%) and cases from the northeast senatorial zone (8.2%) of the state. Significantly higher mortalities (8.8%, P = 0.003) were recorded amongst cases with nasopharyngitis. The odds of diphtheria-related mortality were higher amongst cases who presented clinically with nasopharyngitis and were 4 times more likely to die (adjusted odds ratio = 3.9; 95% confidence interval = 1.1-14.3) compared with those with no nasopharyngitis. CONCLUSIONS: Significantly higher mortalities were recorded amongst diphtheria cases whose samples were not taken, and those with nasopharyngitis. These findings underscored the importance of improved immunisation uptake, early and prompt case detection, investigation and proper management.

Prevalence and clinical profile of heart failure patients with atrial fibrillation in a tertiary hospital in Kano, Nigeria.

Introduction: Atrial fibrillation (AF) is one of the most prevalent sustained arrhythmias that is seen in clinical practice. AF commonly coexists with heart failure (HF) and there is growing evidence that it confers an adverse prognostic impact on the natural course of the disease. We set out to describe the prevalence and clinical profile of HF patients with AF in Aminu Kano Teaching Hospital (AKTH), Kano, Nigeria. Materials and Methods: We conducted a cross-sectional study of all adults aged 18 years and above, who presented at the AKTH, Kano, and were hospitalised for HF. Those who consented were consecutively recruited into the study. Sociodemographic and clinical characteristics of patients at presentation were documented. Thromboembolic risk was assessed using CHA2DS2-VASc scoring system. A 12-lead electrocardiogram recording was obtained from each of the recruited patients to confirm the presence of AF. The prevalence of AF was determined amongst the admitted HF patients. Those with AF were compared with those without AF in terms of sociodemographic and clinical characteristics. Results: A total of 240 Nigerians were recruited. Sixty per cent were female and the whole group had a mean age of 50.85 ± 18.90 years. The prevalence of AF was found to be 12.5% amongst the recruited HF patients. The HF patients with AF had a significantly higher mean age (58 ± 16.7 years vs. 49.8 ± 19.0 years) (P = 0.021), and they also had a higher prevalence of palpitation and body swelling. The mean CHA2DS2-VASc score of the AF patients was 3.4 ± 1.0. Conclusion: AF is prevalent amongst HF patients in our environment with high thrombotic risk. More studies are needed to fully study the prevalence of AF and its clinical profile amongst HF patients in our country.

Factors associated with hypertension among adults in high burden kidney disease areas of Jigawa State, Nigeria: A cross-sectional survey.

Background: Hypertension is the leading risk factor for preventable cardiovascular-related complications and mortalities worldwide. Materials and Methods: A cross-sectional survey was conducted to assess the prevalence and factors associated with hypertension among 361 adults from four local government areas (LGAs) of Jigawa state identified to have high burden of kidney diseases. The Modified WHO STEPS questionnaire and multi-stage sampling technique were employed and data were analysed using IBM SPSS version 22.0. Results: The age of the respondents ranged from 18 to 102 years with a median of 45 (interquartile range = 30-80) years. More than a quarter (34.9%) of the respondents were unemployed. Few reported history of alcohol ingestion (0.8%) and cigarette smoking (1.1%). The prevalence of systolic hypertension was 116 (32.1%), while that of diastolic hypertension was 133 (36.8%). Jahun LGA had higher cases (36.7%) of systolic hypertension, whereas Dutse LGA had higher cases (47.8%) of diastolic hypertension. Systolic hypertension was significantly higher (P < 0.001) among those >35 years of age. The odds of developing systolic hypertension were significantly lower among those between the ages of 18 and 35 years, and those between the ages of 18 and 35 years were less likely to have systolic hypertension than those above the age of 35 years (adjusted odds ratio = 9.0; 95% confidence interval = 4.6-17.6). Similarly, those who reported family history of diabetes and hypertension (P < 0.001) had a significantly higher proportion of systolic hypertension. Conclusions: The prevalence of hypertension was alarming in the high burden kidney disease areas. The government should develop a sustainable model for the mass community screening of risk factors and community-based health insurance for the effective management of all identified cases.

Socio-demographic and Nutritional Factors Associated with Obesity amongst Adults from High Burden Kidney Diseases Areas of Jigawa State, Nigeria: A Community-based Survey.

Background: Obesity is a preventable public health problem associated with a significantly increased risk of non-communicable diseases. This study aimed to find the socio-demographic and nutritional factors associated with obesity amongst adults from high-burden kidney disease areas of Jigawa State, Nigeria. Methodology: A cross-sectional survey was conducted to assess the socio-demographic and nutritional factors associated with obesity among 361 adults from four local government areas (LGAs) of Jigawa state identified to have a high burden of kidney diseases. The Modified WHO STEPS questionnaire and multi-stage sampling technique were employed, and data were analyzed using IBM SPSS version 22.0. Results: The minimum age of the respondents was 18, and the maximum was 102 with a median of 45 (interquartile range = 30-80) years. The prevalence of obesity and overweight in the high-burden LGAs of Jigawa state was 33.0% and 27.1% respectively. Hadejia LGA had the highest (68.1%) prevalence of obesity. The prevalence of overweight was higher in Jahun LGA (38.9%). About one-third (38.2%) had a waist circumference (WC) greater than 88cm. Up to half of the female respondents had a waist-hip ratio (WHR) greater than 0.85. For male respondents, many (74.3%) had a WHR of greater than 0.9, and obesity was significantly higher (39.8%, P s< 0.001) among those ≥40 years of age. Obesity was significantly higher (39.8%,P < 0.001) among those ≥40 years of age, known diabetic, (57.1%, P=0.02), and rare consumption of vegetables, (45.8%, P<0.001).The odds of developing obesity were significantly higher among those who were known diabetics and were 3 times more likely to be obese than those who were not known to be diabetics (adjusted odds ratio [aOR] = 3.1, 95% CI = [1.1-8.9]. Conclusions: The prevalence of obesity was high in the areas with high burdens of kidney disease. The government and relevant stakeholders should develop a cost-effective prevention, early diagnosis, and treatment model.
