The worldwide prevalence of Diabetes Mellitus (DM) associated with Hepatitis C Virus (HCV) infection are reported with higher rates of morbidity and mortality. The frequency of HCV is approximately 3-4 million cases each year and in parallel the incidence of DM is increasing alarmingly. World Health Organization (WHO) has specified that DM will be the 7th leading cause of mortality by 2030. The increasing association between HCV and DM has been indicated by some significant reports recently. HCV infection leads to hepatic steatosis and rapid insulin resistance, which in turn upsurges the risk factors for hepatic fibrosis and hepatocellular carcinoma. This study is designed to examine the association between HCV and DM, and different risk factors associated with HCV infection in Qassim region, Kingdom of Saudi Arabia (KSA). A total of 634 blood samples were obtained from diabetic and non-diabetic patients. These blood samples were first screened for HCV infection by enzyme-linked immunosorbent assay (ELISA) and positive samples were again confirmed by TaqMan HCV quantitative test and the viral load in different samples was estimated. The HCV prevalence was identified as 2.5% in diabetic patients with a positive association between HCV and DM (RR= 1.24, OR= 1.77) which is not significant statistically. However, the HCV prevalence among diabetic females was significantly different from males (p<0.05). The behavioural factors had no significant impact to acquire HCV infection. This study indicated a positive association between HCV and DM. Gender was an association factor in the HCV and DM status. Further studies with larger sample size is significant to properly assess the temporal relationship between HCV and DM.


Hepatitis C Virus, Viral Load, Diabetes Mellitus Type I, Diabetes Mellitus Type II, Qassim Region


Hepatitis C virus infection (HCV) and Diabetes Mellitus (DM) are well-known causes of morbidity and mortality throughout the world. It is now reported that more than 170 M individuals are infected with HCV globally.1-7 Approximately 3-4 million cases occur every year with a significant risk of progression to chronic liver disease, cirrhosis and hepatocellular carcinoma.8,9 The Ministry of Health (MOH) in Saudi Arabia, reported 9000 new cases of viral hepatitis in 2007, in that 32% were HCV infections.9 A Saudi study performed on blood donors showed 0.4 – 1.1% prevalence of HCV infection.10-13 Data on prevalence of HCV infection in the general population in KSA is lacking as no population-based studies have been carried out.9 Diabetes affects all ages, communities and continents. According to a national epidemiological health survey conducted on 16,917 Saudi subjects, the prevalence of DM was found to be 23.7%.14-16

HCV infection notoriously called as a silent disease caused by the HCV is a positive sense, ssRNA virus belonging to family Flaviviridae and genus Hepacivirus.17 It consists of 7 genotypes and 86 subtypes. 5-25% of the patients with chronic HCV pose the risk of developing cirrhosis after 25-30 yrs.18 Genotypes 1 and 4 are responsible for 86% of chronic HCV infections in Saudi Arabia.19-21 HCV is primarily transmitted through exposure of infected blood.22 Unsafely performed injection practices is the most predominant mode for transmission and it accounts to 40% of HCV infections reported worldwide.23

There is mounting evidence on the relationship between HCV and type 2 DM. People infected with HCV were observed to have increased risk of type 2 DM in controlled studies. HCV infection can lead to fibrosis and cirrhosis of the liver which may in turn lead to glucose intolerance and DM.23-25 According to the histological examination on the pancreases from patients with HCV, defects in function and morphology of beta islet cells of pancreas containing desensitized response of insulin to glucose were showed.25,26 HCV is found to induce hepatic steatosis, insulin resistance (IR) and impaired insulin signalling.27 Tumor necrosis factor alpha (TNF-a) can affect the signalling of insulin in patients with HCV.28,29 A large Taiwanian cohort study revealed that patients who developed DM and have chronic HCV, had the highest risk by 2-3-fold for getting liver decompensation and cirrhosis.30 DM also raises the risk of getting hepatocellular carcinoma (HCC) in patients with chronic HCV.31,32 The decreased rates of early virological response as well as sustained virological response (SVR) among patients with chronic HCV infection treated with a combination of ribavirin and pegylated interferon-a (PEG-IFN-a) are related to increasing levels of IR.33-35 There is a direct relationship between IR and high viral load of HCV.36 A study revealed that the prevalence of HCV infection was higher in type 2 diabetic patients as compared to type 1 diabetic patients (84% vs. 16%).37 Furthermore, another study indicated that type-2 diabetes was more common in patients with HCV than in patients with an HBV infection.38

Due to insufficient data on prevalence of HCV and its association with DM in Qassim region, this study was designed to investigate the prevalence of HCV infection; its association with DM and the risk factors associated with HCV/DM comorbidities. The methodology used in the study was represented by Figure 1.

Materials and Methods

Sample study
The cross-sectional study was conducted during the period 2018-2019 in Buraidah, Qassim. All the Saudi nationals who attended the King Fahad Specialist Hospital (KFSH), including Diabetes Centre were invited to participate in this study. Among those, 634 subjects consented to participate and were enrolled in the study by convenience sampling method (the power of the sample size estimate was 0.99). The study was conducted after obtaining due ethical clearance from the Institutional Ethical Committee and Regional Research Ethics Committee (Registration N0. H-04-Q-001). Informed consent was taken from the participants, and consent for the minors was taken from their parent/guardians. Blood samples with aseptic precautions were drawn from all study subjects who attended KFSH above the age of 10 years and were willing to participate in the study. Subjects less than 10 years of age or with pancreatic disease other than DM or with a history of it or with hepatocellular carcinoma or cirrhosis from another cause and subjects who refused to participate in the study were excluded.

Data collection
The participants signed the informed consent and the parental or guardian consent was obtained for minors, respectively. Information was also collected using a pre-structured questionnaire, which included information on demographic characteristics such as gender, age, education level and marital status. Additionally, information on the type of DM, duration of the disease, family history of DM, DM treatment information, and history of exposures to risk factors for example: sharing personal items, injections, history of hospitalization, surgical procedures etc were collected. Clinical information was gathered from routine laboratory tests and medical records: e.g., glucose level and liver function test values were recorded. According to the American Diabetes Association criteria for type 2 diabetes, a person is considered diabetic if HbA1c ≥ 6.5%, Fasting plasma glucose ≥ 126 mg/dl (7.0mmol/l), 2hr plasma glucose ≥ 200 mg/dl (11.1 mmol/l), and Random plasma glucose ≥ 200 mg/dL (11.1 mmol/L).39

Screening for HCV
Screening for HCV was done using Monolisa anti-HCV ELISA kit which is an indirect qualitative enzyme immunoassay for the detection of HCV infection based on the detection of anti-HCV (IgG) antibodies in serum. Positive samples were further confirmed by using TaqMan HCV quantitative test which was done in Nucleic Acid Testing (NAT) section of KFSH, Buraidah. The NAT is considered as the gold standard for detection of HCV replication.40

COBAS AmpliPrep/COBAS TaqMan HCV Test
The quantitative RT-PCR for the confirmation and detection of the viral load of HCV was performed using COBAS AmpliPrep/COBAS TaqMan HCV Test. Classification of viral load result: <60,0000IU/ML was considered low, (60, 0000-80,0000IU/ML) was considered intermediate and >80, 0000 IU/ML was considered as high viral load.41

Statistical Analysis
All the data obtained was analyzed by using Excel, Epi Info™ and SPSS and descriptive statistical analysis was performed.42,43 Results obtained on categorical measurements were designated in numbers (%). Fishers Exact and Cochran’s Mantel-Haenszel tests were used to test associations between the prevalence of HCV among diabetics/non-diabetics and socio-demographic characteristics, behavioural factors and biochemical parameters of liver function by calculating the p value. The results were then presented in tables, charts and graphs. The level p<0.05 was set as statistically significant.


Demographic Characteristics
This study included 634 participants. The majority (26.8%) of participants for this study were between 51-60 years old and at least 3% were between 10-20 years of age. There ratio of females (54.6%) was more than males and more married (83.4%) than single participants in the study sample.

Association between Demographic Characteristics and HCV
There was non-significant association (p >0.05) between all demographic data (age, gender, marital status, Education level) and HCV infection. The age groups 41-50 years, 51-60 years and >60 years showed high percentages of presence of anti-HCV, being 2.2%, 3.0%, and 3.9% respectively, compared to the other age group and male was higher with positive anti-HCV (2.4%) than female (1.7%). Married participants were also higher with anti-HCV positive (2.3%) than non-married (0.9%). The participants who were non-educated had higher percent of anti-HCV positive status (3.0%) than participants with other education levels (Table 5).

Prevalence of HCV in Diabetic and Non-Diabetic Participants
The prevalence of anti-HCV in diabetic participants was 2.5% and there was an association between HCV and diabetes mellitus as the risk difference was 13.4%, while the relative risk was 1.24 and the odds ratio was 1.77. However, the association was not statistically significant as p =0.40; therefore, the null hypothesis was rejected and the alternative hypothesis was accepted (Table 6).

HCV and Diabetes Mellitus
Figure 3 compares the prevalence of HCV and diabetes mellitus in different age groups. It shows that both age groups (51–60 years and > 60 years) have the highest prevalence of HCV and diabetes mellitus (0.5%), while the age groups (10–20 years and 21–30 years) have the lowest prevalence (0.0%). There was non-significant association between HCV and diabetes mellitus that considered all age groups as p =0.74, while in all age groups 10-20 years, 21-30 years, 41-50 years and >60 years, p =1.00. The age group of 31-40 years had p=0.20, and p=0.31 was in 51-60 years’ age group.

There was a significant association between HCV and diabetes mellitus in female (p=0.03), with higher percentage (0.9%), while there was non-significant association between HCV and diabetes mellitus in male (p=0.46) and the percentage in male was lower (0.5%). The association between HCV and diabetes mellitus considered both gender as statistically non-significant (p = 0.50) the percentages for both gender is shown in Figure 4.

Figure 4. HCV vs Diabetes Mellitus with Gender.  It includes four categories: males and females have HCV and DM, have HCV but no DM, have DM but no HCV, no HCV and no DM

A percentage of 1.4% of HCV and diabetes mellitus was found in married participants, while there was no HCV and diabetes mellitus in single participants. Furthermore, there was non-significant association between HCV and diabetes mellitus that considering marital status (p=1.00 for singles, and p=0.37 for married). Non-significant association between HCV and diabetes mellitus including both single and married was found with p =0.60 (Figure 5)

Figure 6. HCV vs Diabetes Mellitus with respect to Education Level. Including three categories: non educated, school educated and university education

Figure 6 illustrated that the highest percentage of HCV and diabetes mellitus were in university education level (0.6%), followed by non-educated level (0.5%), while the lowest percentage was found in school-educated level (0.3%). Furthermore, there was non-significant association between HCV and diabetes mellitus considering all education levels (p= 0.58), while p=1.00 was determined for both non-educated and school-educated participants, and p=0.16 was calculated for university education level.

Clinical Lab Findings
The available records of the levels of liver function tests among the participants with elevated alanine aminotransferase (ALT) and aspartate aminotransferase (AST) 6.7% and 9.1% were found to be anti-HCV positive, respectively. Moreover, there was non-significant association between ALT and HCV (p=0.28) and between AST and HCV (p=0.09) (Tables 9 & 10).

Many studies have suggested the association between the HCV infection and DM.44-48 There are many risk and behavioural factors which can contribute to acquiring HCV infection. The present study assessed the prevalence of HCV in diabetic and non-diabetic subjects and evaluated the association between demographic characteristics and the presence of HCV infection, viral load and DM.

In the present study, the prevalence of HCV in diabetic participants was 2.5% which was higher than what previously reported in Dammam city (1.9%),1 in Turkey (2.2%) and in Tunisia (1.3%).49,50 However, it was lower than what reported in USA (4.2%), in T2D reported from India (5.7%)51,52; in Pakistan (36%),53 in Nigeria (11%) and among T2DM in study reported in Taiwan (6.8%).54,55

The prevalence of HCV in non-diabetic participants was 1.4% which was higher than what previously reported in Dammam city (0.074%)1, in Yemen (1.3%), in Tunisia (0.6%) and in Turkey (0.5%).49,50,56 However, it was lower than what reported in USA (1.6%) and in Taiwan (2.6%).51,55

A significant association between the female gender, Anti-HCV and DM was determined, which is in an agreement with the study conducted in USA, which showed that the diabetic HCV cohort had a higher proportion of female participant.5 However, another study showed that among the HCV infected patients, males had an increase frequency of DM.44

This study has also showed a higher percentage of HCV in older age group such as age more than 60 years when considered to the total participants. HCV percentage was also high among older diabetic participants as suggested by studies conducted in Dammam and Egypt.1,57 A study conducted in central region of Yemen also revealed that there was increasing in seropositivity of HCV with older age.56

This study found that there is no significant association between HCV and type of DM, as previously determined in Dammam city which found that 15% of type 1 diabetic patients had HCV compared to 35% of patients with type 2 diabetic who had HCV.1 A study conducted in Pakistan showed that out of 100 diabetic participants, only 36 had HCV seropositivity and all of them had type 2 DM.53 Furthermore, a following study in the same country found strong relationship between HCV and type 2 DM.58

The present study found that the association between duration of DM and HCV was not statistically significant. A study conducted in Dammam, Saudi Arabia has shown that 85% of HCV cases were with duration of more than 5 years of diabetes mellitus, compared to 15% in those with equal or less than 5 years. The association was significant between chronicity of diabetes mellitus and HCV1. However, a previous study showed that the majority of patient with HCV seropositive had less than 5 years duration of DM.53

There is an evidence that the insulin users are more prone to acquire infection since the unsafe injection and contaminated equipment’s may lead to the infection, however this study showed no significant association between insulin injection and HCV. The percentage of anti-HCV was lower in insulin users compared to participants taking oral medication. A study conducted in France found no difference in diabetic participants with seropositivity for HCV comparing with the mode of treatment, being 62.5% for oral agents, 37.5% for insulin treatment.59 However, a recent study revealed a higher infection among insulin users 65% compared to those with non-insulin treatment 35%.1

No significant association between sharing personal item, tattooing, blood transfusion, hospital admission and surgical operation, IV drug use, hijama and HCV was determined in the present study. A recent study also showed a non-significant association between surgery and blood transfusion with HCV.52 However, a previous investigator found a significant association between most of these behavioural factors and HCV like sharing personal item, tattooing and blood transfusion, while dialysis, surgery, hospital admission had non-significant association with HCV. Moreover, a higher number of operation and hospital admission were found to have significant association with HCV.1 Furthermore, a study conducted in Nile delta showed that the risk factors like blood transfusion and surgeries were significantly associated with HCV seropositivity when considered people with age of more than 20 years.60 However, another study showed non-significant association between IV drug, sharing sharp item and hijama by health care worker with HCV, while a significant association between tattooing and hijama by people with HCV was found.61

No significant association was found between transaminase and HCV, which was unlike to the study conducted in Dammam city, showing the elevation of transaminases were a predictor for HCV.1 A previous study in Pakistan found that high ALT levels were in associations with HCV seropositivity in diabetic participants.53


The present study shows a positive correlation between HCV and diabetes mellitus. Demographic characteristic like gender, had a significant influence on HCV and DM status. Different behavioral factors, however, had no significant impact on acquiring HCV infection. Further investigations are required to determine whether the HCV infection can lead to DM or vice versa. A temporal relationship between HCV and DM needs to be established with the help of prospective studies. This study recommends that a good awareness about increasing HCV incidence and preventive control measures in the region need to be performed. Future screening of HCV among patients suffering from diabetes mellitus and vice versa is also highly recommended. Further study is required to find the prevalent genotype among diabetic patients in Qassim region.
