Diabetes and Hepatopathy: Epidemiological and Clinical Profile in the Internal Medicine Department of CHU Donka ()
1. Introduction
Diabetes is a chronic hyperglycemia resulting from genetic and environmental phenomena and can lead to long-term complications affecting small and large vessels. The diagnostic criteria for diabetes are: if the blood glucose level ≥ 1.26 g/l on 2 occasions fasting for more than 8 hours or venous blood glucose at any time of the day ≥ 2 g/l with signs of hyperglycemia or blood glucose 2 hours later (OGTT at 75 g of glucose) ≥ 2 g/l or HbAlc ≥ 6.5 [1]. Diabetes represents for the World Health Organization (WHO) one of the 4 noncommunicable diseases targeted with cardiovascular diseases, cancers and respiratory diseases [2]. It is estimated that there are 463 million adults aged 20 to 79 years living with diabetes and 79.4% of them live in low-income and middle-income countries. According to 2019 estimates, 578.4 million adults aged 20 - 79 years are expected to be living with diabetes by 2030 and 700.2 million by 2045, representing a prevalence of 10.9% [3]. Chronic liver disease, defined as liver disease that persists over a prolonged period, is a major public health problem. Viral infections, especially hepatitis B and C are recognized as common causes of chronic liver disease, affecting approximately 325 million people worldwide [4]. A link between chronic viral hepatitis and type II diabetes mellitus was first suspected many years ago, many trials have reinforced the belief that the 2 entities are indeed linked, although the exact pathophysiological mechanisms have not been established, hepatitis C (HCV) is more frequently associated with diabetes, compared to hepatitis B virus (HBV) infection [5]. In Belgium in 2014, Jaafar J. et al. [6] reported that type 2 diabetic patients frequently had hepatic steatosis or other chronic liver diseases, moreover 30% of cirrhotic patients had diabetes. In Morocco in 2009, Latrech et al. [7] revealed that the prevalence of diabetes in cirrhotic patients was 48%. In Guinea in 2007, Baldé et al. [8] found 8.6% of diabetics with hepatitis B. Given the hospital frequency of this association in our department, the delay in consultation and the lack of recent data motivated the choice of this study.
2. Methods
It was a study descriptive type prospective study lasting 15 months from March 1, 2023 to June 30, 2024. We included in this study all patients admitted for liver disease on the grounds of known diabetes or incidental discovery whose age ≥ 18 years, regardless of gender, from any origin supported in the internal medicine department and with diagnostic criteria blood glucose ≥ 1.26 g/l [7 mmol/l] on two occasions after fasting for more than 8 hours, or venous blood glucose at any time of the day ≥ 2 g/l [11.1 mmol/l] with signs of hyperglycemia or blood glucose 2 hours after a glucose load (OGTT at 75 g of glucose) ≥ 2 g/l [11.1 mmol/l], HbAlc ≥ 6.5 after ruling out hemoglobinopathies and having given verbal consent having given verbal consent. Data collection was carried out on of all the files of patients followed up in the Internal Medicine department hospitalized and presenting with liver disease associated with diabetes, we have: in a first step, we have identified the data from the inter-hospital system (SIH) of the Donka national hospital of patients followed up for liver diseases associated with diabetes, then in a second step, we have filled out the individualized survey form from the data collected in SIH, and finally we have analyzed each survey form according to our patient inclusion criteria. The data collected from the results on the survey forms were entered and then analyzed using Epi info software version 3.5.4.
The data was collected anonymously, used for strictly scientific purposes and confidentiality was respected.

4. Discussion
Chronic liver disease and diabetes constitute a major public health problem with significant morbidity and mortality, Chronic infection with hepatitis C virus (HCV) results in the occurrence of severe chronic liver disease with metabolic complications such as diabetes mellitus, which occupies an important place according to literature data.
During the period, out of a total of 809 hospitalized patients, 50 patients had a combination of liver disease and diabetes, is 6.2% (Table 1). Kabbaj N [9] had reported 17.2% in his study. In another study, conducted in the United States during the period 1999-2010, the prevalence of hepatitis B infection in adult diabetic patients was 60% [10].
The low prevalence in our study reflects the underdiagnosis of liver diseases in patients with diabetes, which under diagnosis requires targeted interventions to address the many challenges facing health structures in underdeveloped countries. According to CDC investigations, hepatitis B and C viruses can be contracted by: shared use of blood glucose monitoring devices, shared use of the same injection equipment, such as syringes or insulin pens, cross-contamination of clean supplies with devices soiled blood glucose monitoring used by health home agencies, inaccurate sterilization of soiled equipment, poor hand hygiene [11] (Table 2).
The average age reported during our study was 54.7 years with extremes of 25 and 95 years. Ameur FZ et al. [12] had found an average age of 54 years. On the one hand, diabetes is a disease that increases with age, this is probably linked to the accumulation of bad eating habits, to the aging of cells as the body ages and on the other hand, according to literature the Metabolic factors are likely to interfere with the natural history of HCV infection, the rate of progression of fibrosis is high in obese subjects with a BMI > 30 kg/m2.
The male sex was the majority in our study. Diarra MT et al. [13] had found a female predominance with respective sex ratios of 0.38. This result may be justified by the occurrence of complications with poor lifestyle such as tobacco, alcohol, multiple sexual partners Physical asthenia was the most common manifestation found in our study. GEIST C. [14] in 2013 in the emergency room of Strasbourg which had a frequency of 21%. This could be explained by the fact that asthenia is a frequent reason for consultation in internal medicine but also reflects the chronic mode of evolution of the disease.
Digestive hemorrhage (DH) due to rupture of esophageal varices (RVO) and hepatic encephalopathy (HE) were the most common complications encountered during our study. Ouavene JO et al. [15] in their study reported that the main complications were dominated by digestive hemorrhage (19.5%) and hepatic encephalopathy (19%). Stroke and diabetic retinopathy represented the most common chronic complications found during our study. Mahamane SA et al. [16] found 79.5% for neuropathy, 32.1% for diabetic retinopathy. This result could be explained by the delay in diagnosis and patients consulting health facilities at the stage of complications or decompensation of diabetes or hepatopathy, our results are consistent with the data in the literature. During its progression, diabetes can cause serious complications affecting the heart, blood vessels, eyes, kidneys and nerves. Cohort or case-control studies in the United States, Europe and the Asia-Pacific region show that DT2 increases the risk of developing HCC by 2 to 3 times, regardless of cirrhosis or the concomitant presence of other causes of chronic liver disease. The risk of HCC appears to be correlated with the duration and control of diabetes [17] (Table 3, Table 4).
5. Conclusion
Chronic liver disease in diabetic patients was not negligible during our study and concerned an average age of 55 years, mostly male and type II diabetic. Stroke and diabetic retinopathy were the most common complications of diabetes and progressive complications were marked by hepatic encephalopathy and HCC. Emphasis should be placed on strengthening preventive methods for diabetes and chronic liver disease. Further studies are necessary to determine the role of each pathology in the occurrence of complications.
