Coronavirus disease 2019 morbid pulmonary pathology: What did we learn from autopsy examinations?

BACKGROUND

Despite the rapidly expanding data on clinical, epidemiological and radiological aspects of coronavirus disease 2019 (COVID-19), little is known about the disease's pathological aspects. The scarcity of pathological data on COVID-19 can be explained by the limited autopsy procedures performed on deceased patients.

AIM

This work aims to review and summarize the pulmonary pathological findings observed in COIVD-19 deceased individuals based on recent case series reports published in English up to September 2020.

METHODS

A search in Google Scholar, PubMed^Ò, MEDLINE^Ò, and Scopus was performed using the keywords "autopsy and COVID-19," "postmortem and COVID-19," and "pulmonary/lung pathology and COVID-19."

RESULTS

Pulmonary autopsy hallmark findings of COVID-19 cases demonstrate the presence of diffuse alveolar damage. The presence of pulmonary thrombi was reported in the majority of patients. Cellular alterations included type 2 pneumocyte hyperplasia, inflammatory cell infiltrates predominantly by lymphocytes, other mononuclear cells, and neutrophils as evident by their specific immunohistochemical markers. Electron microscopy confirmed the presence of virus particles in different cell types, including types 1 and 2 pneumocytes.

CONCLUSION

The few emerging autopsy reports have substantially contributed towards our understanding of COVID-19 pulmonary histopathological aspects. COVID-19 caused acute severe respiratory manifestations that are the leading cause of morbidity and mortality in infected patients. More studies and research are needed to understand the inflammatory processes and histopathological changes associated with COVID-19 in African populations.

RELEVANCE FOR PATIENTS

Postmortem investigations advance important mechanistic knowledge on COVID-19 pathophysiology and clinical outcomes and could facilitate provisions for targeted therapies.

The prevalence and risk factors for systemic hypertension among Sudanese patients with diabetes mellitus: A survey in diabetes healthcare facility

BACKGROUND AND AIMS

Diabetes and hypertension are common chronic diseases that affect about one fifth of Sudanese adults. The aim of this study was to assess the prevalence of hypertension among Sudanese individuals with diabetes.

MATERIALS AND METHODS

This a survey in diabetes healthcare facility-based study that recruited 266 individuals with diabetes mellitus (DM). Data was collected using a standardized pretested questionnaire, and was analyzed by performing descriptive and inferential statistics through SPSS program.

RESULT

The study showed that average age of participants was 58.7 (±10.5 SD) years, males were 59% and most of the participants (72.6%) from urban areas. Diabetes for 1-5 years was observed in 10.9% and for more than 11 years in 71.4%. The majority (91.7%) had type 2 diabetes mellitus while only (8.3%) had type 1 diabetes. The prevalence of hypertension was 47.7% among the study group, this was significantly associated with age (p value 0.016), and retinopathy (p value 0.001). Logistic regression analysis showed that age, body mass index (BMI), serum creatinine and retinopathy had statistically significant associations with the presence of hypertension (p values 0.002,0,016, 0.008,0.001) respectively.

CONCLUSION

Prevalence of hypertension in Sudanese patients with diabetes presenting to diabetes clinic was 47.7%, and it increased with age and presence of retinopathy. Risk factors of hypertension were age, body mass index (BMI), serum creatinine and retinopathy.

Assessment of lifestyle modifications among Sudanese individuals with diabetes: The situation so far and the need to do more

BACKGROUND

Inadequate lifestyle practices among individuals with diabetes may influence the progression of diabetes and its complications. The aim of this study was to assess the lifestyle practices among individuals with diabetes in Sudan.

METHODOLOGY

This was a descriptive, cross-sectional, health facility-based study conducted in 3 diabetes centers treating individuals with diabetes. The data were collected using a standardized pretested metabolic questionnaire about lifestyle and were analyzed by performing descriptive and inferential statistics through SPSS program version 23.

RESULTS

A total of 528 patients with diabetes answered the questionnaire. There were 52.1% of female participants and 72.9% of urban residents. 23.9% were obese, regular exercise was reported by 27.7%, and no exercise by 17%. There was a statistically significant association between lifestyle practices and gender (P < 0.001), age (P < 0.001), educational level (P = 0.002), marital status (P < 0.001), duration of diabetes (P < 0.001), hypertension (P < 0.001), high-density lipoprotein (P < 0.001), low-density lipoprotein (P < 0.001), and HbA1c level (P < 0.001). Logistic regression analysis showed male gender and education were significantly associated with lifestyle changes. Men were more likely to engage in favorable lifestyle practices than women (P < 0.001), while those with no formal education were less likely to engage in healthy lifestyle (P < 0.001).

CONCLUSIONS

Health authorities in Sudan will need to put more efforts into education for promoting self-awareness and good lifestyle practices in the population with diabetes.

An outbreak of measles in gold miners in River Nile State, Sudan, 2011

Background

Despite the wide use of vaccination, measles outbreaks still occur.

Aims

This study assessed cases notified during a measles outbreak in northern Sudan in 2011 and the response of the health authorities to contain the outbreak.

Methods

The records of all measles cases reported to the River Nile State health ministry in 2011 from the Abu Hamad locality, a gold-mining area, were reviewed together with the actions of the health authorities at the time of the outbreak. Seventeen gold-mining clusters were included. Data on demographic, clinical, geographic and chronological characteristics of the cases were extracted.

Results

The outbreak occurred from 27 January to 3 May 2011 with the peak in epidemiological week 9. A total of 445 measles cases were recorded, giving an incidence of 27.1 per 10 000 of the mining and resident population. Most cases (87.4%) were aged between 15 and 34 years. High fever was the most common symptom (99.3% of the cases), followed by conjunctivitis (80.4%); haemorrhage was recorded in 29.4%. Most cases (84.9%) were unvaccinated. Six deaths occurred (case fatality: 1.3%); two from cerebral coma and four from haemorrhagic shock. Severity of disease was significantly associated with place of origin of the cases (P = 0.003).

Conclusion

The measles outbreak in the gold-mining areas in Abu Hamad had serious consequences attributed to poor environmental conditions, overcrowding, poor nutrition and lack of vaccination. The health authority response helped end the outbreak. The local health authority should consider the gold-mining areas as a potential risk to public health in their future plans.

The prevalence and risk factors of stroke among Sudanese individuals with diabetes: Cross-sectional survey

INTRODUCTION:

Diabetes complications in Sudan were increasing at an alarming rate. The aim of this study was to assess the prevalence of stroke among Sudanese individuals with diabetes.

METHODOLOGY:

This cross-sectional study recruited 283 individuals with diabetes from three diabetes centers in Sudan. Data were collected using a standardized pretested questionnaire, and data were analyzed using Chi-square and logistic regression analysis.

RESULTS:

The average age of participants was 51 (±12 standard deviation) and 35% were aged between 51 and 60 years. Females were 66.8%, and most of the participants (73.9%) were from urban areas and 66.1% received formal education between primary school and university. Body mass index (BMI) classification showed that 34.3% were obese, 31.8% overweight, and 30.4% normal BMI. Diabetes for 1-5 years were observed in 71.7% and for more than 10 years (12%). The majority, i.e., 94.3% had type 2 diabetes mellitus while only 5.7% had type 1. Only one-third of the participants were able to achieve glycosylated hemoglobin (HbA1c) target for diabetes control. The prevalence of cerebrovascular accident (CVA) was 2.5%, hypertension (HTN) was 20%, ischemic heart disease 3.2%, and neuropathy was 45.6%. Chi-square test showed significant association between HbA1c, serum creatinine, total cholesterol, triglyceride, low density lipoprotein, high density lipoprotein level, and the presence of CVA. Logistic regression analysis showed HbA1c, and the duration of diabetes are significantly associated with the presence of CVA (P = 0.010, 0.014).

CONCLUSION:

The prevalence of stroke among Sudanese individuals with diabetes was around 2.5%. The main risk factors were HbA1c, HTN, and duration of diabetes.

Comparison of serum lipid profile in type 2 diabetes with and without adequate diabetes control in Sudanese population in north of Sudan

BACKGROUND

Diabetes mellitus (DM) is a major health problem in Sudan and is a leading cause of morbidity and mortality. Dyslipidemia is a major complication of diabetes and an important risk factor for cardiovascular disease (CVD). The objective of this study was to determine the prevalence of dyslipidemia and its co-relation with the glycemic control in individuals with diabetes in River Nile State, Sudan.

METHODS

Individuals with diabetes attended, Naserudin Karamalla Diabetic (NKDM) Centre, in Atbara teaching hospital during study period, who volunteered to participate were included. Only those on treatment for DM for at least one year were included. Venous samples were collected for cholesterol, triglycerides, HDL, LDL, blood glucose and Glycosylated hemoglobin. Participants were interviewed using standardized pretested questionnaire to record medical history and sociodemographic characteristics. Blood pressure, body mass index (BMI) and waist circumference were measured.

RESULTS

A total of 188 individuals were included. The mean age was 49.5 + 13.9 and (128) 68.1% were females. Most patients were having DM for at least 3-5 years 69 (36.7%). Poor diabetes control (HbA1c >7) was recorded in 87.2%, hypercholesterolemia, hypertriglyceridemia and high LDL were identified in 36.6%, 27.7% and 26.6% respectively. In addition, HDL was low in 61.2% of patients.

CONCLUSION

Low HDL is a prominent feature in two thirds of individuals with diabetes, while high cholesterol and high triglyceride were seen in over one quarter.

Hypertension in Sudanese individuals and associated risk factors: the critical intersection between salt and sugar intake

Background

Hypertension is common problem across the globe. The aim of this study was to assess the prevalence of hypertension and impact of salt and sugar intake in Sudanese population.

Methods

A descriptive cross sectional study, included 323 of participants in Khartoum state. The data collection was performed to gather demographic information, physical activity and dietary habits. In addition to measurement of blood pressure (BP), weight and height measurement for calculation of body mass index (BMI).

Results

Among the 323 respondents (males were 171), 29 (9%) are known hypertensive, 60 (18.6%) are diagnosed to be hypertensive. Therefore, the prevalence of hypertension is 27.6%. Hypertension was significantly associated with male sex, increasing age, obesity, low physical activity, salt and sugar intake. Logistic regression analysis showed that increasing age, obesity and high sugar intake are absolute predictors for hypertension in Sudanese population.

Conclusions

The prevalence of hypertension was 27.6%. Hypertension in Sudanese individuals was associated with high sugar and salt intake, obesity and increase in age. Therefore, decreasing sugar and salt intake should be advocated by health authorities and the public in Sudan.

Sugar intake in Sudanese individuals was associated with some features of the metabolic syndrome: Population based study

AIM

The aim of this study was to assess the level of sugar intake among Sudanese individuals.

MATERIALS AND METHODS

A cross-sectional study with 323 participants. Respondents were grouped by the total intake of added sugars into two groups, one group with sugar intake more than 200 calories per day and other group with sugar intake less than 200 calories per day. Demographic data were collected with anthropometric measurements like body mass index (BMI) and waist circumference. Chi square, T-Tests and stepwise logistic regression were used (a p-value <0.05 was considered significant).

RESULTS

High sugar intake was noted among 74.6% participants and among overweight, normal weight, followed by obese (p<0.015) and then individuals with diabetes and hypertension (p <0.000 and 0.038 respectively).High sugar intake was also associated with abdominal obesity (p<0.016), mean age of 33 years old (p<0.00) and being married and single(p<0.003). Stepwise logistic regression showed diabetes and BMI<25 were absolute predictors for sugar consumption with p value of 0.001 and 0.039 respectively. Individuals with diabetes have more than five times probability to consume large amount of sugar (Odd ratio 5.6), while those with BMI<25 have two times risk of consuming more sugar compared to those with BMI>25 group (Odd ratio 2.1).

CONCLUSION

A large percentage of Sudanese population uses a high amount of sugar. High sugar intake was associated with normal weight, overweight, abdominal obesity, diabetes and hypertension. Absolute predictors of high sugar intake were diabetes and normal body weight.

Increasing prevalence of type 2 diabetes mellitus and impact of ethnicity in north Sudan

BACKGROUND

Diabetes mellitus constitutes a global health threat, with increasing burden of disease in low and middle-income countries witnessing ongoing epidemiological transition including Sudan.

AIMS

To study the prevalence of type 2 diabetes mellitus (T2DM) and prediabetes and determine the relationship to gender, age, waist circumference, body mass index, residence and ethnicity among the adult population in north Sudan.

METHODS

A cross-sectional, population-based study in Northern State and River Nile State using random multi-stage cluster sampling targeting 5376 participants from 14 localities divided into 60 urban and 40 rural clusters. In each cluster, 60 households were studied. Blood glucose level and anthropometric measurements were recorded and a questionnaire containing demographic data was obtained from each participant.

RESULTS

The prevalence of T2DM among participants was 18.7% and prediabetes was 12.9%. Among people living with T2DM, 694(71.0%) were known cases of T2DM, whereas 284(29.0%) were newly diagnosed cases. The significant associated risk factors for T2DM included urban residence (AOR 1.23, 95%CI 1.09-1.41), age above 60 years (AOR 4.77, 95%CI 4.04-5.63), obese BMI (AOR 1.26, 95%CI 1.03-1.55) and central obesity (AOR 1.39, 95%CI 1.14-1.68). Compared to indigenous population, individuals of Egyptian descents (AOR 1.28, 95%CI 1.04-1.57) and mixed origin (AOR 1.24, 95%CI 1.04-1.48) had increased risk of T2DM.

CONCLUSION

The prevalence of T2DM and prediabetes in north Sudan have increased significantly since 1996 with variations between ethnicities which showed to be an independent risk factor for T2DM. Health authorities are recommended to set plans to meet the health needs of these communities.

Prevalence and determinants of undernutrition among children under 5-year-old in rural areas: A cross-sectional survey in North Sudan

Background

Child malnutrition is a major public health problem in developing countries. Therefore, the aim of this study was to estimate the prevalence of undernutrition among children <5 years in River Nile state (RNS) in North Sudan.

Subjects and Methods

A cross-sectional household survey was done in four localities in RNS. Using Multistage Cluster sampling, 1635 under 5 years' children had participated. Pretested questionnaire and anthropometric measures were used during data collection. The analysis was done using SPSS software program version 21 and World Health Organization (WHO) Anthro 2005 software. Indices were reported in z-scores and compared with the WHO 2005 reference population to determine the nutritional status of children.

Results

Among 1,447 surveyed children, the prevalence of stunting, underweight, and wasting were 42.5%, 32.7%, and 21%, respectively. Stunting was highest among the 48-60 months of age group (82.5%). Boys had poorer indicators of undernutrition in comparison to girls. Geographically stunting was more prevalent in Berber locality. Infectious diseases (gastroenteritis and respiratory symptoms) and incomplete vaccination were significantly associated with wasting (P = 0.007, P = 0.013, and P = 0.008). Poor socioeconomic status (P = 0.043), poorer household sanitation (P = 0.022), large family size, lack of family spacing, and infants weaned suddenly were regarded as risk factors for undernutrition.

Conclusion

There was a high prevalence of undernutrition in the 4^th and 5^th year of life in RNS population, with significant gender imbalance. Our survey highlighted the importance of urgent need to improve child health in this region.

HIV-Associated Nephropathy in Africa: Pathology, Clinical Presentation and Strategy for Prevention

The human immunodeficiency virus (HIV) infection can lead to progressive decline in renal function known as HIV-associated nephropathy (HIVAN). Importantly, individuals of African ancestry are more at risk of developing HIVAN than their European descent counterparts. An in-depth search on Google Scholar, Medline and PubMed was conducted using the terms "HIVAN" and "pathology and clinical presentation", in addition to "prevalence and risk factors for HIVAN", with special emphasis on African countries for any articles published between 1990 and 2017. HIVAN is characterized by progressive acute renal failure, proteinuria and enlarged kidneys. A renal biopsy is necessary to establish definitive diagnosis. Risk factors are male gender, low CD4 counts, high viral load and long use of combined antiretroviral medication (cART). There is a wide geographical variation in the prevalence of HIVAN as it ranges from 4.7% to 38% worldwide and little published literature is available about its prevalence in African nations. Microalbuminuria is a common finding in African populations and is significantly associated with severity of HIV disease progression and CD4 count less than 350 cells/µL. Other clinical presentations in African populations include acute kidney injury (AKI), nephrotic syndrome and chronic kidney disease. The main HIV-associated renal pathological lesions were focal segmental glomerulosclerosis, mainly the collapsing form, acute interstitial nephritis (AIN), and immune complex-mediated glomerulonephritis (ICGN). HIV infection-induced transcriptional program in renal tubular epithelial cells as well as genetic factors is incriminated in the pathogenesis of HIVAN. This narrative review discusses the prevalence, presentation, pathogenesis and the management of HIVAN in Africa. In low resource setting countries in Africa, dealing with HIV complications like HIVAN may add more of a burden on the health system (particularly renal units) than HIV medication itself. Therefore, the obvious recommendation is early use of cART in order to decrease risk factors that lead to HIVAN.

Low levels of physical activity in Sudanese individuals with some features of metabolic syndrome: Population based study

BACKGROUND

The aim of this study was to evaluate the level of physical activity among Sudanese population.

METHODS

A descriptive cross sectional study composed of 323 participants from Khartoum state, Sudan. Data collected using pretested designed questionnaire based on previously validated Global Physical Activity Questionnaire. The demographic and physical measurement including blood glucose, anthropometric and blood pressure.

RESULTS

The Mean age of participants was 35.5. Males were 59.9% and females 47.1% and the prevalence of inactivity was 53.8%. Despite the fact that males are more active than females (P<0.000) physical activity tends to decrease with age but this not statistically significant. Physical activity is significantly decreased with obesity, higher education and doing sedentary jobs (P<0.018, P<0.000 and P<0.000 respectively). While majority of individuals with hypertension and pre-hypertension tend to do less physical activity (P<0.045 and P<0.008 respectively). Logistic regression analysis shown that gender is absolute risk factor for physical activity. Males have more than three times probability of being physically active than women OR3.82 (1.91-7.30). In this study, physical activity was not affected by central obesity (P<0.497), diabetes (P<0.378) and being married or not (P<0.135).

CONCLUSION

Physical activity in Sudanese women was significantly decreased in comparison with men.

Diabetes complications in Sudanese individuals with type 2 diabetes: Overlooked problems in sub-Saharan Africa?

BACKGROUND

Diabetes mellitus (DM) is a major health problem in Sudan and is a leading cause of morbidity and mortality. The objective of this study is to determine the prevalence of complications of type 2 diabetes across different cities in the country.

METHODS

Individuals with type 2 diabetes, who have been on treatment for DM for at least one year and volunteered to participate, were selected from two diabetes centers in Sudan (Khartoum and Atbara). Participants were interviewed using standardized pretested questionnaire to record medical history, socio-demographic, life style characteristics and presence of complications of diabetes.

RESULTS

Four hundred and twenty four individuals with T2DM were included in this study (50.7% males and 49.3% females). Good glycemic control (HbA1c <7) was found in 15.7%. Hypertension was reported in 39.9% and myocardial infarction in 5.9%, while high cholesterol and triglyceride noted in 59.9%, 32.5% respectively. Low HDL was noted in 52.6%. Other complications like peripheral neuropathy, retinopathy and diabetic foot were observed in 68.2%, 72.6% and 12.7% respectively. Factors significantly associated with these complications were longer duration of diabetes (P<0.001), and living in urban areas (P<0.004).

CONCLUSION

High prevalence of complications of type 2 diabetes were observed especially in those with longer duration of diabetes and poor control.

Prevalence and trends of obesity among adult Sudanese individuals: Population based study

AIM

The prevalence of obesity has increased across the globe in particular in Africa. The aim of this study was to determine the prevalence of obesity in Sudan.

MATERIAL AND METHODS

Descriptive, cross sectional study recruited 7239 individuals. Demographic and clinical data were collected by an interview using a pretested standardised questionnaire. Anthropometric measurements including body weight, height and waist circumference have been taken using standardized techniques and calibrated equipment. Body mass index (BMI) has been calculated.

RESULTS

Total of 7239 persons completed the questionnaires; the results showed that prevalence of obesity was found to be 21.2%, with a higher rate of obesity in females than males (26.3% versus 13.8%). The prevalence of central obesity was also higher in women (36.7%) than men (17.6%).The prevalence of overweight was 34.9%. The overall prevalence of overweight/obesity was 56.1%. Obesity determined by BMI was associated with hypertension and diabetes. While central obesity was associated with an increase in age, female, diabetes and hypertension.

CONCLUSION

The prevalence of obesity was 21.2%. Obesity and central obesity have a higher prevalence among Sudanese women. Obesity and central obesity were associated with diabetes and hypertension.

Diabetes, metabolic syndrome and dyslipidemia in people living with HIV in Africa: re-emerging challenges not to be forgotten

BACKGROUND

The current challenge in managing people living with human immunodeficiency virus (PLWHIV) includes the identification and monitoring for comorbid health risks associated with HIV and its treatment and longer survival. Dyslipidemia, diabetes mellitus and metabolic syndrome are increasingly seen in PLWHIV.

OBJECTIVE

In this narrative review, we aimed to summarize the current knowledge about diabetes, dyslipidemia and metabolic syndrome in PLWHIV in Africa and also to discuss the challenges that patients as well as health authorities in Africa may face.

METHODS

PubMed and Google scholar published-English literatures concerning earlier mentioned entities regardless of time limit were critically reviewed.

RESULTS

The prevalence of metabolic disorders in HIV population in Africa was estimated to range from 2.1% to 26.5% for diabetes and 20.2% to 43.5% for pre-diabetes, 13% to 58% for metabolic syndrome and 13% to 70% for dyslipidemia.

CONCLUSION

The management of metabolic disorders and cardiovascular disease risks related to HIV is complex especially in Africa due to healthcare resources, but our experience suggests that metabolic clinic is beneficial to patients and staff and should be an important part of HIV services especially as the older HIV population is increasing. In this context, cardiovascular risk assessment of HIV-infected patients will become an important component of care in developing countries in Africa and strategies are needed to deal with progressive increase in the epidemic of type 2 diabetes, dyslipidemia and metabolic syndrome.

Glycaemic control in Sudanese individuals with type 2 diabetes: Population based study

BACKGROUND

Diabetes mellitus (DM) is a major health problem in Sudan and is a leading cause of morbidity and mortality. The objective of this study was to determine the prevalence of glycaemic control among individuals with type 2 diabetes across different cities in Sudan.

METHODS

Individuals with type 2 diabetes attending selected diabetes centres in Sudan, who had been on treatment for DM for at least one year and volunteered to participate were included. Participants were interviewed using standardized pretested questionnaire to record medical history, sociodemographic and life style characteristics. Lipid profile and glycosylated hemoglobin were tested by calibrated laboratory methods. Blood pressure, Body mass index (BMI) and waist circumference were measured. Chi squared and logistic regression were used as statistical methods.

RESULTS

A total of 387 individuals with T2DM were included in this study (50.4% males and 49.6% females). The glycemic control indicator (HbAIc>7) was poor in 85% of patients. Factors associated with poor glycemic control were prolonged duration of diabetes (p=0.03), high plasma triglyceride (p=0.02), low high density lipoprotein (HDL) level (p=0.04) and low glomerular filtration rate (GFR) (P=0.01). Logistic regression analysis showed that low GFR is independent factor with poor diabetes control.

CONCLUSION

High prevalence of uncontrolled diabetes (85%) is noted in Sudanese individuals with type 2 diabetes.

Prevalence and Risk Factors for Acute Coronary Syndrome Among Sudanese Individuals With Diabetes: A Population-Based Study

Background

Acute coronary syndrome (ACS) is common with diabetes. The aim of this study was to establish prevalence and risk factors for ACS among Sudanese individuals with diabetes mellitus (DM).

Methods

A descriptive cross-sectional study was conducted in Khartoum State and Atabra (North of Sudan). The data collection was performed through pretested questionnaire, in addition to measurement of lipid profile and HbA1c.

Results

Among the 496 respondents, 234 (48.4%) were males and only 15 of them had ACS, while 255 (51.6%) were females and 12 had ACS. Therefore, the prevalence of ACS was 5.44% (95% confidence interval (CI): 3.45-7.44%). The unadjusted risk factors for ACS were age (P = 0.0008864), duration of DM (P = 0.01105) and presence of hypertension (P = 0.0006021). The presence of albuminuria, gender, and body mass index (BMI) was not associated with ACS. In addition, parameters like HbA1c, high-density lipoprotein (HDL), triglyceride and low-density cholesterol (LDL) were also not associated with ACS. Logistic regression analysis showed that duration of diabetes (odds ratio (OR) for below 5 years' history of DM = 0.175 (95% CI for OR: 0.180 - 0.835), P = 0.04051) and hypertension (OR = 2.462 (95% CI for OR: 1.007 - 6.500), P = 0.039) were absolute risk factors for ACS.

Conclusion

The prevalence of ACS is estimated to be 5.44%. ACS in Sudanese individuals with DM was associated with hypertension, increase in age and increase in duration of DM.

Non-Alcoholic Fatty Liver Disease in Africa and Middle East: An Attempt to Predict the Present and Future Implications on the Healthcare System

Non-alcoholic fatty liver disease (NAFLD) encompasses a group of hepatic diseases that range in severity. NAFLD is increasingly recognized as an epidemic among different populations, including those in Africa and the Middle East. The objective of this narrative review is to document the prevalence of and risk factors for NAFLD in Africa and the Middle East and the potential implications on the healthcare systems. An in-depth search on Google Scholar, Medline and PubMed was conducted using the terms "non-alcoholic fatty liver disease" and "non-alcoholic steatohepatitis", in addition to "prevalence and risk factors for NAFLD", with special emphasis on Africa and the Middle East countries. There were three types of epidemiological studies that included prevalence, risk factors and management/complications of NAFLD. There was noticeable variation in the prevalence of NAFLD among different countries, based on the variation in the prevalence of risk factors (type 2 diabetes, obesity, metabolic syndrome and dyslipidemia) and the diagnostic tool used in the study. However, the highest prevalence rate was reported in some Middle East countries. In Africa, there were few studies about NAFLD and most reported variable prevalence rates. There is an increasing prevalence of NAFLD as a result of the increasing risk factors, particularly in the Middle East, while in Africa, the situation is still unclear. Health providers in these regions are faced with many challenges that need urgent plans.

Obesity among Sudanese adults with diabetes: a population-based survey

BACKGROUND

The aim of this study was to determine the prevalence of obesity among Sudanese individuals with diabetes.

METHODS

Demographic and clinical data from 1,337 individuals with type 2 diabetes were collected using a pretested, standardized, interviewer administered questionnaire. Subjects were recruited from three states namely Khartoum, Northern and River Nile States. Anthropometric measurements including body weight, height and waist circumference were determined using standardized techniques and calibrated equipment.

RESULTS

Total of 1,337 subjects with type 2 diabetes from Khartoum and North of Sudan were enrolled in this study and completed the questionnaires; the results showed that prevalence of obesity among individuals with diabetes was found to be 24.5%, with a higher rate of obesity in females than males (29.2% versus 18.1%). The prevalence of central obesity was also higher in women (43.6%) than men (21.8%). The prevalence of overweight was 39.9%. The overall prevalence of overweight and obesity was 64.4%. Obesity was associated with age, sex and blood pressure. While central obesity was associated with an increase in age, female sex and hypertension. Logistic regression analysis showed that female sex and hypertension are absolute risk factors for both obesity and central obesity.

CONCLUSIONS

The prevalence of obesity was 24.5% and overweight was 39.9% among Sudanese individuals with diabetes and more among women than men. Obesity and central obesity were significantly associated with female sex and hypertension.

Diabetes and Ramadan: A concise and practical update

Despite the fact that the month of Ramadan includes 29–30 days and the duration of fasting for each day can last for between 12 and 16 h, it was estimated that a large number of individuals with diabetes do fast during Ramadan. In light of recent advancement of new pharmacological agents, drugs such as vildagliptin, sitagliptin, and liraglutide were found to be safe to use during this month of fasting. These therapeutic agents can also be used in combination with metformin. The use of sulfonylureas, in most of the recent guidelines about diabetes and Ramadan, seems not to gain much support due to the risk of hypoglycemia. In this review, we also addressed the use of insulin injection, insulin pump, and education before, during, and after Ramadan. Further research is needed to determine (i) the therapeutic benefit of new antidiabetic agents and (ii) the benefit of new technologies for the treatment of diabetes.

Metabolic control targets in Sudanese adults with type 1 diabetes: A population-based study

Background:

Type 1 diabetes is a challenging metabolic disorder for health authorities in Sudan. The objective of this study was to assess the level of glycemic control and to determine the prevalence of dyslipidemia and complications among individuals with type 1 diabetes in Sudan.

Materials and Methods:

Individuals with type 1 diabetes, who were having the disease for at least 1 year, were invited to participate in this study. Data were collected from two diabetes centers, in the Capital Khartoum and Atbara City, North of Sudan. Participants were interviewed using standardized pretested questionnaire to record medical history, sociodemographic data, and life style characteristics. Blood pressure, body mass index, and waist circumference were measured. Blood samples were taken for measurement of lipid profile and glycosylated hemoglobin.

Results:

A total of eighty individuals with type 1 diabetes volunteered to participate in this study, 37.5% of males and 62.5% of females. Majority of the patients were aged between 40 and 70 years old. There was poor glycemic control (glycosylated hemoglobin >7%), in 83.8%. Age and sex were significant factors associated with poor glycemic control in this cohort. High cholesterol, triglyceride, and low density lipoprotein were seen in 76.2%, 27.5%, and 48.8% of participants, respectively. Low high density lipoprotein was seen in 33.8%. Hypertension was determined in 21.3%. Peripheral neuropathy, visual impairment, diabetic foot, and myocardial infarction were seen in 50%, 48.8%, 18.8%, and 2.5% of patients, respectively.

Conclusion:

Sudanese adults with type 1 diabetes have poor glycemic control, high prevalence of dyslipidemia, and long-term complications.

Prevalence of diabetes mellitus and its risk factors in urban communities of north Sudan: Population-based study

BACKGROUND

Diabetes mellitus (DM) is a major health problem in Africa and worldwide. The prevalence of diabetes is expected to increase at alarming rate in Africa. Its estimated that around 20 million Africans are now living with diabetes, comprising a challenge for health systems at present and in the future. The aim of the present study was to determine the prevalence of undiagnosed and diagnosed DM and impaired glucose tolerance (IGT) in adult urban communities of the River Nile State (RNS), north Sudan.

METHODS

The present study was a cross-sectional community-based study in which participants were randomly selected from the four main cities of the RNS, on a house-to-house basis. Blood glucose was tested and all participants completed a questionnaire to obtain demographic, clinical and social data. Blood pressure and anthropometric measures were also recorded.

RESULTS

In all, 954 adults (518 females; 54.3%; mean [±SD] age 39.5 ± 16.7 years; range 18-90 years) participated in the survey. The overall prevalence of DM was 19.1% (182/954), whereas that of IGT was 9.5% (91/954). Among the diabetic group, 125 (68.7%) had known diabetes, whereas 57 (31.3%) were newly diagnosed during the study. Increasing age, a family history of diabetes, central obesity, abnormal body mass index, and hypertension were significant risk factors for DM.

CONCLUSIONS

There is high prevalence of DM and glucose intolerance in the urban population of the RNS. Screening for diabetes in individuals with any feature of metabolic syndrome is recommended.

Potential Benefit of Metformin as Treatment for Colon Cancer: the Evidence so Far

Metformin is known as a hypoglycaemic agent that regulates glucose homeostasis by inhibiting liver glucose production and increasing muscle glucose uptake. Colorectal cancer (CRC) is one of the most common cancers worldwide, with about a million new cases diagnosed each year. The risk factors for CRC include advanced age, smoking, black race, obesity, low fibre diet, insulin resistance, and the metabolic syndrome. We have searched Medline for the metabolic syndrome and its relation to CRC, and metformin as a potential treatment of colorectal cancer. Administration of metformin alone or in combination with chemotherapy has been shown to suppress CRC. The mechanism that explains how insulin resistance is associated with CRC is complex and not fully understood. In this review we have summarised studies which showed an association with the metabolic syndrome as well as studies which tackled metformin as a potential treatment of CRC. In addition, we have also provided a summary of how metformin at the cellular level can induce changes that suppress the activity of cancer cells.

Epidemiology of tuberculosis and evaluation of treatment outcomes in the national tuberculosis control programme, River Nile state, Sudan, 2011-2013

Tuberculosis is a major health problem in Sudan, a country that carries 11-15% of the tuberculosis burden in the Eastern Mediterranean Region. This study aimed to describe the epidemiology of tuberculosis in River Nile State and to compare treatment outcomes with WHO recommended indicators. A descriptive study was conducted on data collected from records of 1221 patients registered at tuberculosis management units over the 3 years 2011-2013. The mean age of cases was 37.7 (SD 21.5) years and 65.9% were males; 76.3% were pulmonary tuberculosis and 36.9% were sputum smear-positive cases. Average values for all outcome indicators were suboptimal, notably rates of case notification (30.8 per 100 000), case detection (10.3%), treatment success (79.6%), treatment failure (3.0%), default (8.1%) and death (8.0%). Of the 264 patients tested for HIV, 3.8% were positive. Outcome indicators for the national tuberculosis control programme are lagging behind the required targets.

High prevalence of hypertension among an ethnic group in Sudan: implications for prevention

OBJECTIVE

Hypertension is an emerging non-communicable disease in developing countries. Due to its silent nature and serious complications, active screening is essential in order to prevent complications. For instance, premature mortality from cardiovascular diseases could be prevented by the effective control of hypertension. The aim of this study was to determine the prevalence of undiagnosed hypertension among Nuba ethnic group living in Atbara city, north Sudan and to identify the associated risk factors.

SUBJECT AND METHODS

All consenting 500 adults from Nuba tribe who live in El Wihda District, Atbara were included. Blood pressure (BP) and body mass index were measured. Standard interviewing procedures were used to record medical history, socio-demographic data, and lifestyle characteristics.

RESULTS

Among the 500 participants, females were 364 (72.8%) and males were 136 (27.2%). The overall prevalence of undiagnosed hypertension was 49.4% (30.8% stage 1 hypertension and 18.6% stage 2 hypertension). In addition, 41% of the population was having prehypertension. The significant risk factors for high BP were: male sex, age above 45 years, overweight, illiteracy, and alcohol consumption.

CONCLUSION

Undiagnosed high BP is very common among Nuba ethnic group; therefore, active screening and early management are recommended to prevent complications.

Prevalence of and risk factors for hypertension among urban communities of North Sudan: Detecting a silent killer

Background:

Hypertension is a common global health problem in many countries including Sudan. The objective of this study was to determine the prevalence of and risk factors for high blood pressure (BP) in River Nile State (RNS), Sudan.

Materials and Methods:

A community-based, cross-sectional study was conducted by a house-to-house survey; all consented adults from the main four cities, Atbara, Shendi, Ed Damer, and Berber, were interviewed using standardized pretested questionnaire to record medical history, sociodemographic and lifestyle characteristics. BP was measured using the standardized technique. Body mass index, waist circumference, and blood glucose were also determined.

Results:

A total of 954 individuals were included in the study. The mean age was 39.5 ± 16.6 years and 54.3% were females. The prevalence of hypertension was 35.7% and the newly diagnosed cases were 22.4%. Increasing age, low educational level, diabetes mellitus, obesity, and central obesity were found to be risk factors for hypertension.

Conclusion:

Hypertension is diagnosed in more than one-third of the population living in urban communities of RNS and correlates well with features of the metabolic syndrome.

The Changing Pattern of Hospital Admission to Medical Wards: Burden of non-communicable diseases at a hospital in a developing country

OBJECTIVES

This study aimed to determine the pattern of hospital admissions and patient outcomes in medical wards at Atbara Teaching Hospital in River Nile State, Sudan.

METHODS

This retrospective cross-sectional study was conducted from August 2013 to July 2014 and included all patients admitted to medical wards at the Atbara Teaching Hospital during the study period. Morbidity and mortality data was obtained from medical records. Diseases were categorised using the World Health Organization's International Classification of Diseases (ICD) coding system.

RESULTS

A total of 2,614 patient records were analysed. The age group with the highest admissions was the 56-65-year-old age group (19.4%) and the majority of patients were admitted for one week or less (86.4%). Non-communicable diseases constituted 71.8% of all cases. According to ICD classifications, patients were admitted most frequently due to infectious or parasitic diseases (19.7%), followed by diseases of the circulatory (16.4%), digestive (16.4%) and genito-urinary (13.8%) systems. The most common diseases were cardiovascular disease (16.4%), malaria (11.3%), gastritis/peptic ulcer disease (9.8%), urinary tract infections (7.2%) and diabetes mellitus (6.9%). The mortality rate was 4.7%.

CONCLUSION

The burden of non-communicable diseases was found to exceed that of communicable diseases among patients admitted to medical wards at the Atbara Teaching Hospital.

Bone marrow aspiration in north Sudan: the procedure, indications and the diagnostic value

INTRODUCTION

Bone marrow aspiration (BMA) is a common and useful investigation tool in clinical practice to obtain information about both hematological and non-hematological disorders. The aim of the work was to identify the main indications for BMA in Atbara city, north Sudan and to determine the common diagnoses encountered.

METHODS

All reports of BMA carried out during a 6-year period from 2009 to 2014, in the Modern Specialized Laboratory (the only site where BMA is conducted in Atbara) were reviewed. The information extracted included the main indications for performing this procedure, age groups involved, and the most common diagnoses established. A specially designed form was used for this purpose and the data were analyzed using SPSS computer program.

RESULTS

A total number of 112 cases were subjected to bone marrow aspiration. The most frequent indications were: pancytopenia 43(38.4%), anemia 39 (34.8%), and suspected leukemia 13 (11.6%). In 86(76.8%) cases, BMA provided either the diagnosis or diagnostic clues to the disease process, while 26 (23.2%) of the aspirates revealed a normally functioning marrow.

CONCLUSION

Bone marrow aspiration is an important investigation for establishing the diagnosis in many medical conditions. The most common indication for this procedure in our study was pancytopenia and the most common finding was aplastic anemia.

Cytomorphology of palpable breast lesions: Diagnostic utility of FNAC in a developing country

BACKGROUND

Breast lesions including breast cancer represent a major public health issue in Sudan. Fine-needle aspiration cytology (FNAC) is an established, simple, highly accurate, minimally invasive, and cost-effective method of diagnosing most breast lesions. The aim of this study is to document the most common breast conditions diagnosed by means of FNAC over a two-year period in Atbara, a city in north Sudan.

METHODS

A retrospective, descriptive, cross-sectional, laboratory-based study in which records of all palpable breast lesions diagnosed by FNAC in the years 2012 and 2013 were reviewed and analyzed.

RESULTS

The total number of cases studied was 232; most subjects, 222 (95.7%), were females. The age range was 15-90 years (mean 38.2). Painless lump was the most common 190 (81.9%) clinical presentation. The left breast was affected more often than the right breast, 56.0% vs. 40.5%. Benign conditions were 167 (72%). Malignant neoplasms were 65 (28.0%). The most important associations with malignancy were female sex, age above 35 years, multiparity, painless lump at upper outer quadrant of left breast, lump size above 2 cm and the presence of an enlarged ipsilateral axillary lymph node at presentation.

CONCLUSION

In the northern part of Sudan, the prevalence of malignant breast lesions diagnosed by FNAC is more than one fourth of all cases presenting with palpable breast lumps. FNAC is a technique that is ideal for use in resource-limited health settings.

Undiagnosed hypertension in a rural community in Sudan and association with some features of the metabolic syndrome: how serious is the situation?

BACKGROUND

Hypertension is the leading risk factor for death and disability globally. Its prevalence is increasing worldwide especially in low and middle income countries. It is considered a silent killer because it has no specific symptoms and thus can go unnoticed for many years, only presenting for the first time with serious complications. The situation of undiagnosed hypertension in Sudan has not been fully investigated before.

OBJECTIVE

To determine the prevalence of undiagnosed hypertension in the rural communities of River Nile State (RNS), Sudan and to assess the associated risk factors.

METHODS

A cross-sectional community-based study, in which 1099 volunteer adult participants from the rural communities in RNS, not known to be hypertensive, were included. Blood pressure was measured as well as anthropometric measurements. The WHO stepwise approach for non-communicable diseases surveillance was used for data collection. A p value below 0.05 was considered statistically significant.

RESULTS

There were 461 males (41.9%) and 683 females (58.1%). The male to female ratio was 1:1.4. The age range was 18-90 years, with a mean age of 39.6 (STD ± 15.9). The prevalence of undiagnosed hypertension was 38.2%, with a prevalence of 36.7% among males and 39.3% among females. There were significant associations between undiagnosed hypertension and increasing age, obesity, illiteracy and diabetes mellitus (p < 0.05).

CONCLUSION

This study uncovers a hidden epidemic of a silent killer in the rural communities of RNS. Urgent interventions are required to address this serious health epidemic.
