An inflammatory response occurs as a result of the immune response to high blood glucose levels as well as the presence of inflammatory mediators produced by adipocytes and macrophages in fat tissue.

This low and chronic inflammation damages the pancreatic beta cells and leads to insufficient insulin production, which results in hyperglycemia. Hyperglycemia in diabetes is thought to cause dysfunction of the immune response, which fails to control the spread of invading pathogens in diabetic subjects.

Therefore, diabetic subjects are known to more susceptible to infections. Mercey Livingston CNET Contributor. Mercey Livingston is a health and wellness writer and certified Integrative Nutrition Health Coach.

A normal blood glucose level is between 70 and 99 milligrams per deciliter. If your fasting blood glucose test is milligrams per deciliter or higher on two tests, you likely have diabetes. An AC blood test is also used for diagnosis. It shows your average blood glucose levels over several months.

A normal AC level is 5. If your test results are high, you may have diabetes. If you have type 1 diabetes, you'll need to learn how to manage it. You'll need to test your blood sugar, or glucose levels every day. You may have to check them several times during the day if you need regular insulin therapy or if you are having symptoms.

You will also need to have regular AC tests. This test shows how well you've been controlling your blood sugar over a three-month period. You'll also need to take extra care when you're sick. Getting sick can make controlling your blood sugar difficult.

Good blood sugar and blood pressure control helps reduce your risk for complications. Even with good control, you may need to see an eye doctor, dentist, and foot specialist on a routine basis for monitoring and treatment.

You should also wear a medical identification bracelet. This can help you get the right treatment during an emergency. If treated, type 1 diabetes goes away. True or false? The answer is false. Type 1 diabetes is a condition that doesn't go away.

Adults don't get type 1 diabetes. Type 1 diabetes is more commonly diagnosed in children and teens, but anyone can get it at any age.

Since most PMN functions are energy-dependent processes [34] , an adequate energy production is necessary for an optimal PMN function. Glucose needs insulin to enter the PMNs to generate this energy, which may explain the improvement of the chemotactic response after the addition of these two substances.

Conflicting data have been reported about the in vitro adherence of diabetic PMNs without stimulation [25 , 27 , 31 , 34 , 35]. In contrast, no differences have been found between diabetic and control PMNs after stimulation [27 , 31]. No correlation was found between plasma glucose or HbA1c and adherence [25 , 27 , 31].

However, in a small number of DM type 1 and DM type 2 patients with untreated hyperglycemia, the decreased adherence of PMNs to nylon fiber columns increased after the hyperglycemia was corrected [34 , 35]. Of course adherence to nylon fiber columns is not the same as to endothelial cells as a first step in the inflammation reaction.

However, again a better regulation of the DM seemed to increase the host response. PMNs of diabetic patients have shown the same [25 , 33] and a lower [31 , 36] phagocytotic capacity compared to PMNs of controls.

The mean HbA1c concentration was lower better regulation in patients without impaired phagocytosis [33] than in those with impaired phagocytosis [31 , 36].

One study [36] showed an inverse relationship between the HbA1c levels and the phagocytotic rate. Another study [37] showed that the decreased phagocytosis improved, but did not become normal after 36 h of normoglycemia.

Therefore, it seems that impairment of phagocytosis is found in PMNs isolated from poorly regulated patients and that better regulation of the DM leads to an improved phagocytotic function.

Chemiluminescence CL corresponds to the emission of light directly or indirectly produced in the course of a chemical reaction. This phenomenon is often used to evaluate the oxidative potential of PMNs, a process during which free radicals are synthesized early in the phagocytotic process [31 , 38].

CL correlates well with antimicrobial activity [39] and may be used as a measure of phagocytotic capacity [38].

Compared to controls, CL at baseline was higher [31] or the same [36 , 39] in PMNs of diabetic patients. These studies [31 , 36 , 39] also showed that, after stimulation, the CL of diabetic PMNs was lower than that of control PMNs.

It is possible that the reaction of diabetic PMNs to stimuli is quenched as a result of the higher resting CL. In our study [33] , we did not find any differences in CL after stimulation between diabetic patients and controls.

In general, however, the patients in our study were better regulated than those in the earlier studies, which may probably explain these different results.

Data about the bactericidal activity of diabetic PMNs have yielded conflicting results [25 , 26 , 33 , 37]. In general, however, the killing capacity of diabetic PMNs is lower than that of control PMNs. Again, differences in either the patient characteristics see Section 2.

An impaired killing function of diabetic PMNs was found in all studies using Staphylococcus aureus as the microorganism [25 , 26 , 37] , but not in the studies in which the killing of C. albicans [33] was used as the measure. Killing was impaired in one study that used nondiabetic serum for opsonization [37] , but not in another [33].

Thus, based on these studies we cannot draw any conclusions about the effect of nondiabetic serum on the killing of diabetic cells. No correlation was found with glycemic level [25 , 26 , 37] , although some studies have shown that bactericidal activity improved, but did not normalize after achieving normoglycemia [6 , 37].

In a study in our hospital [33] , we were unable to demonstrate any differences in chemotaxis, phagocytosis, CL, and killing between PMNs of diabetic women with bacteriuria, diabetic women without bacteriuria, and nondiabetic controls.

Furthermore, an earlier study showed no differences in phagocytosis and killing between diabetic patients with and without recurrent infections [26]. So, these studies do not indicate that the presence of infections influences PMN functions.

In conclusion, besides some of the conflicting results in studies mentioned above, different disturbances in diabetic compared to control PMN functions are described. However, the clinical relevance of these in vitro studies remains uncertain, mainly because of the differences in the tests performed.

It is possible that only a combination of defects in PMN functions plays a role in vivo. Most studies show an improvement of PMN functions after a better metabolic regulation of DM.

Both impaired chemotaxis and phagocytosis of the monocytes of diabetic patients have been described [1 , 40]. Since plasma from healthy controls does not cause any significant change in the phagocytotic capacity of diabetic monocytes [40] , it seems that this impaired function is caused by an intrinsic defect in the monocytes themselves.

A lower immune response in children with DM type 1 compared to controls was found after intradermal instead of intramuscular administration of the hepatitis B vaccine [5].

It has been suggested that this lower response is probably partly the result of an impaired macrophage function in this patient group [5]. The pathogenic mechanism remains unclear.

Further research has to be done to explain this interesting phenomenon. Adherence of a microorganism to mucosal or epithelial cells is an important step in the pathogenesis of infections. Host-related factors may influence this adherence.

For example, women with recurrent urinary tract infections have a greater adherence of E. coli to their vaginal and buccal cells compared to controls [41]. albicans infection is frequently found in diabetic patients. Since infection mostly is preceded by colonization Aly et al. investigated which risk factors increased the risk of Candida carriage in diabetic patients [42].

Risk factors for oral Candida carriage in patients with DM type 1 were a lower age and a higher HbA1c level poor regulation of DM. Continuous wearing of dentures and the presence of glucosuria also an indication of a poor DM regulation increased the risk of Candida carriage in DM type 2 patients, the mean number of cigarettes smoked per day was correlated with Candida carriage in DM type 1 and type 2 grouped together [42].

Cameron et al. extracted lipids from human buccal epithelial cells and found, using chromatogram overlay assays, that some C. albicans strains bind to fucose-containing and other C.

albicans strains to N -acetylgalactosamine-containing lipids extracted from human buccal cells. The authors conclude that the existence of several adhesin-receptor systems contributes to the virulence of C.

albicans [43]. The carbohydrate composition of receptors probably plays an important role in the susceptibility to infections.

It has been shown that severely ill patients have a decreased amount of galactose and sialic acid on their buccal cells, compared with minimally ill patients and healthy controls. The investigators mentioned that these receptor changes possibly lead to an increased adherence of microorganisms and play a role in the high prevalence of Gram-negative bacterial colonization in the respiratory tract of these patients [44].

This mechanism of increased adherence, due to an altered receptor carbohydrate composition, is possibly also present in diabetic patients. Buccal cells from 50 diabetic patients DM type 1 and type 2 showed an increased in vitro adherence of C. albicans compared to buccal cells from controls [45]. No relationships, however, were found between the frequency or quantity of Candida and age, duration, regulation, or type of DM [45].

This increased adherence to diabetic cells might also play a role for other microorganisms, for example the adherence of E. coli to uroepithelial cells, which would explain the increased prevalence of infections in patients with DM. In conclusion, disturbances in cellular innate immunity play a role in the pathogenesis of the increased prevalence of infections in DM patients Table 1.

In general, a better regulation of the DM leads to an improvement of cellular function. A second important mechanism is the increased adherence of the microorganism to diabetic cells. Deresinski S. Google Scholar. Carton J. Maradona J. Nuno F. Fernandez-Alvarez R. Perez-Gonzalez F.

The small intestine does the following: - It absorbs nutrients from food, which it sends to the large intestine for elimination. Prev Next. Apr 25, Type 2 diabetes is a metabolic disorder that can lead to serious health problems.

With type 2 diabetes, the body doesn't use insulin as well as it should. One of the main complications of type 2 diabetes is an impaired or weakened immune system, making you more vulnerable to infections and other diseases.

What is the immune system? The immune system is the collection of cells and organs that work together to fight disease. The organs of the immune system are your thymus, spleen, lymph nodes and bone marrow.

These organs make white blood cells WBCs , including T-cells and B-cells. These WBCs help protect against infections from viruses and bacteria. The spleen and lymph nodes produce antibodies that destroy germs or mark them for destruction by other WBCs.

Other parts of the immune system are phagocytes, which engulf bacteria or any harmful substance to the body, as well as natural killer cells NKC that attack cells in the body with abnormal proteins.

How do WBCs work? The cells of the immune system have a particular structure. The T-cells, in particular, have two molecules that stick out from their central body or nucleus area.

These are called 'tails', and they are like paddle wheel-like appendages that move around the cells of the immune system using motors to push them in different directions. So how does this affect the immune system? If you do not make enough insulin, your body cannot use the glucose you eat as an energy source, so it uses it instead to make chemicals needed by the immune system.

These chemicals are called 'cytokines', and one of the main ones is interleukin 6 IL
