Morbi Infectious Mortality of Diabetics Hospitalized at the Medical Clinic of Abass Ndao Health Center

Introduction: Diabetes is a public health problem and is exposed to some complications, particularly infectious. The work on this entity remains segmentary in Africa. The objective was to describe the morbi infectious mortality of the diabetics at the Medical Clinic II of Abass Ndao Health Center of Dakar. Patients and Methods: This was a cross-sectional, descriptive and analytical study conducted from 01 January 2016 to 31 December 2016. It covered patients with diabetes hospitalized during the study period. Epidemiological data and infectious diseases were evaluated. Results: During the study period, 346 diabetics have respected the inclusion criteria. These were 165 men (47.68%), a sex ratio of 0.91. The mean age was 56.17 years. The age group of [60 69 years] accounted for 31.5% and 95.6% of the patients came from the Dakar region. The average age of diabetes was 10.31. Diabetes had been evolving for less than 5 years in 25.15% of patients and inaugural in 11.46%. About 82.36% of our patients had type 2 diabetes. The acute complications of diabetes were ketoacidosis (51.89%), hyperosmolar hyperglycemia (0.58%), and hypoglycemia (1.45%). The mean infections were the skin and soft tissues (54.91%), urogenital infections (16.18%), respiratory infections (14.45%), malaria (3.46), infections of the skin and soft tissues were dominated by the diabetic foot (41.90%). The 125 non-diabetic patients developed 38 infectious pathologies, the main ones being respiratory infections (24.32%), infections of the skin and soft parts (24.32%). HIV infection was observed in 0.28% of diabetics and 8.10% of non-diabetic patients. 93 patients died (15.70%). Fifty-one of them died of infectious diseases (54.8%), 42 non-infectious diseases (45.16%), and subjects aged over 60 years, representing 72.54%. The means of consultation was 30 days. The highest rates of lethality were diabetes (37.41%), acute gastroenteritis (17.64%), and acute pyelonephritis (12.5%).

Introduction
Diabetes is a public health problem due to medical, social and financial implications [1].
The International Diabetes Federation (IDF) 2015 estimates report a prevalence of 8.8%.Prevalence in sub-Saharan Africa increased from 4.8% to 5.7% [2].In Senegal, prevalence data remains approximate.According to IDF's 2015 estimates, 3.24% of the Senegalese population would be diabetic [2] [3].As a result, diabetes leads to chronic complications and increases susceptibility to infections through reduced lymphocyte response [4].According to the World Health Organization, infectious diseases are the leading cause of morbidity and mortality in developing countries in general and Africa in particular [5].The few existing data in the field relate to epidemiological, clinical and evolutionary aspects.This study had motivated this study with the objective of specifying the proportion of infectious diseases and identifying the main causes of death in the context of these conditions in the internal medicine department of the Abass Ndao Health Center in Dakar.

Materials and Methods
It's about a descriptive cross-sectional study carried out at the internal medicine department of the Abass Ndao Health Center in Dakar from 1 January 2016 to 31 December 2016.It focuses on diabetic patients of all types aged less than 10 years hospitalized in the department of internal medicine (department affiliated to the national reference center in the management of diabetes and metabolic diseases since 1960).Non-diabetic subjects hospitalized during the study period and diabetic subjects with incomplete records were not included.A pre-established questionnaire or inquiry had been used to collect data relevant to the evaluation.Data collection was carried out on patient records and the hospitalization register.For this survey, we selected the following variables: -Socio-demographic characteristics: sex, age grouped by age and occupation, provenance; -The study of diabetes mellitus: age, type of diabetes, nature of ongoing treatments, cardiovascular risk factors and chronic complications of associated diabetes, level of glycemic control using capillary blood glucose; -Clinical characteristics: diagnosis, consultation time, duration hospitaliza-tion and the evolution of patients.The data for the clinics that contributed to the diagnosis and management of the patients, and resulting from the feasible examinations at the Abass Ndao Health Center, were: 1) thick blood glucose and blood smear for malaria, 2) cytobacteriological and mycology of the CSF for meningitis, 3) the search for acid-alcohol-resistant bacilli (BAAR) on sputum and gastric tubing liquid for tuberculosis, 4) HIV serology, 5) chest X-ray, 6) other biological analyzes (blood cultures, coprocultures, ECBU, transaminases, HBsAg and AgHBe, AcHBc).The statistical analysis was carried out by the Epi Info 6.0 software.

1) Sociodemographic characteristics
During the study period, we have 383 patients.Among these patients, there were 346 diabetics who met the inclusion criteria (90.33%) and 37 patients without diabetes (9.66%).There were 165 men (47.68%) and 181 women (52.31%), a sex ratio of 0.91.The mean age was 56.17 years with extremes of 15 to 90 years.The age group of 60 years and 69 years represents 109 cases (31.5%) of the hospitalized patients.In our study, 95.6% of the patients came from the Dakar region.The Table 1 shows the socio-demographic characteristics of the subjects.
2) Diabetes study The mean age of diabetes was 10.31 years with extremes of 0 to 38 years.Diabetes evolved for less than 5 years in 25.15% of patients and inaugural in 11.46%.Approximately 82.36% of our patients had type 2 diabetes.The treatment was essentially insulin in 48.71% and oral anti-diabetics in 42.30%.The acute complications of diabetes were ketoacidosis (51.89%), hyperosmolar hyperglycemia (0.58%), hypoglycemia (1.45%), electrocardiographic signs suggestive of coronary artery disease (30.6%).Mean fasting blood glucose was 3 g/l with extremes of 0.4 and HI.Only 63 patients had blood glucose (<2 g•l).
Table 2 shows the distribution of patients according to the infectious pathologies observed.4) Causes of death Among the 592 hospitalized patients with diabetes, 93 died (15.70%).Fifty-one of them are infectious diseases (54.8%), 42 non-infectious diseases (45.16%).Patients over 60 years of age and 725.4% and mean consultation time were 30 days.The causes of death of the 51 patients who died of infectious diseases are mainly Open Journal of Endocrine and Metabolic Diseases dominated by diabetic foot 36 cases, pneumonia 5 cases and acute gastroenteritis 3 cases (Table 2); the prevalence of malaria was 1.96% in these subjects was 74.3%.The mortality rate for infectious diseases was 14.73%.In the non-diabetic patients, five deaths with HIV prevalence were observed in 20% of the patients.Mortality rates were highest in the diabetic foot (37.41%), acute gastroenteritis (17.64%) and acute pyelonephritis (12.5%).The mortality rate for indeterminate infections and malaria was 10% and 8.33%, respectively.Table 3 shows the distribution of patients according to the clinical characteristics of the living and deceased patients.

Discussion
Infectious medical pathologies were the first cause of morbid mortality in the internal medicine department of the Abass Ndao Health Center.Indeed, there are 53.41% of the pathologies responsible for hospitalizations and 57.14% of the causes of death in the service during the period of study.This retrospective study, which may be underestimating the reality of infectious pathology in the internal medicine department due to non-analyzed records for missing data, is the first of its kind carried out in our department.The prevalence of infection (58.78%) was as high in hospitalized patients with diabetes as in patients who died.In Africa, infections, as the main causes of decompensation of diabetes, interrupted therapeutic [6].This is in agreement with other authors.In Senegal, Sarr [7] found 78% of concomitant infections and in Algeria Boutabia [8] found a predominance of infectious factors in 51.7% of cases in his series.Thus, the causes of morbidity were dominated by infections (16.98%), respiratory infections (14.45%), malaria (3.46%), digestive infections (6.93%), skin infections and soft tissues and oral infections (5.49%).The infectious pathologies remain the same with a variable distribution of the reports in the literature.Our study differs from that of Sarr [7] and Umpierrez [9] found a predominance of urogenital and bronchopulmonary infections.This is due to the fact that there is a proximity to the podiatry unit that refers to unbalanced patients with skin infections.Diabetics are more prone to infections of the skin and soft tissues.These infections may occur during the course of the disease or may be the first sign of diabetes presentation [10] and may be more severe in these populations [11].Skin and soft infections are the leading cause of morbidity in our series.Skin infections were dominated by the diabetic foot (41.90%).The latter arrives in hospital at a stage of gravity which can lead to amputation.This requires effective therapeutic education to improve the amputation rate.The average age of our patients (56.17 years) was similar to that found by the Masoodi team (50.5 ± 13.3 years) [12].The age range of [60 -69] represents 31.5%.However, the male predominance with a sex ratio of 0.91 found in our study (47.68%) is not shared with the literature [12] [13].Infection is one of the complications revealing diabetes as in Uganda [13].In our study it is in 11.46%.
Ignorance due to lack of information on routine diabetes screening and neglect of diabetes symptoms would be the cause of this delay in diagnosis [14].The average diabetes seniority was 10.31 years higher to that reported by Raherison [15] in Madagascar (6.69 years) and Masoodi (6.6 ± 5.6 years) [12].The infection leads to an imbalance of diabetes [16].A hyperglycemia greater than 2 g/l is found in our study in 76.39%.The acute complications of diabetes were ketoacidosis (51.89%), hyperosmolar hyperglycemia (0.58%), and hypoglycemia (1.45%).
Respiratory infections are represented in our study (14.45%).This rate is lower than in Burkina Faso [17] and Madagascar [15] with 47% and 40.74%, respectively.Tuberculosis was a common lung infection in our patients.There does not appear to be a prevalence of tuberculosis in diabetic patients in developed countries.However, in the developing regions of the world, tuberculosis continues to be a major challenge.We have already documented tuberculosis as a major lung infection in diabetic patients [18].It has been suggested that the recrudescence of tuberculosis may explain a high-level infection in diabetic patients in developing countries.There is also evidence of an increase in the rate of tuberculosis in diabetic patients and new patients in tuberculosis patients in Africa [19].Urinary tract is the most prevalent in the prevalence of infection among diabetic patients [20].It represents a rate of 16.18% in our study.High rates were found in the Sharikstudy of 28.42% [21].This finding should prompt us to ask for more explorations of urinary tract biology because these infections can most often be asymptomatic.HIV infection was observed in 0.28% of diabetics and 8.10% of non-diabetic subjects.This low rate is explained by a demand for retroviral serology in our patients.Indeed, immunodeficiency syndrome is a disease characterized by clinical polymorphism.Hence, it is necessary to think about and carry out HIV tests.We have found a mortality rate similar to that reported by Shah, et al. (15%) [22] and lower by that of Esper, et al. (18.5%) [23].Subjects aged over 60 years were strongly represented (72.54%).This is probably due to a delay in taking care of us.The average time for consultation was 30 days.Mortality rates were highest (37.41%), acute gastroenteritis (17.64%).The mortality rate of undetermined infections and malaria was 10% and 8.33%, respectively.The mean hospital stay of our patients was between those reported by the Mokhtar team (10 days) [24] and the team of Rachdi (20 days) [25].Infections in diabetics always increase economic and hospital costs by prolonging the hospital stay.
