What Causes Fever In People With Diabetes

Fever Of Unknown Origin by Geetha Mary Philips

Fever is often a sign of infection somewhere in the body. It is an important immune system function that sometimes serves to kill the invading organism. People with diabetes are prone to several types of infection. It is important for a person with diabetes to seek treatment for infection or a chronic fever of unknown origin, as an acute illness can make diabetes more difficult to manage.

Chinese Herbs For Treatment Of Fever Of Unknown Origin

Unfortunately, modern Western treatment had probably made him more ill, as antibiotics and some of the anti-inflammatory medications cause nausea and stomach pain. I discharged him from the hospital and started him on traditional Chinese herbal remedy to boost and balance his yin energy. His fever subsided within days, and other clinical manifestations also improved very quickly. The point I am trying to make here, is that high fever is not only seen in people with yin energy excess, it may also be seen in individuals with yang energy deficiency. If an incorrect diagnosis is made, treatment not only is ineffective, it may make things a lot worse.

It’s All About The History In Diagnosing Fever Of Unknown Origin

There are 4 types of fever of unknown origin, and distinguishing among them starts with the first step: Look for clues from the history and other presenting symptoms.

When encountering a fever of unknown origin , a clinician’s first step should be the same as with any puzzling patient: Look for clues from the history and other presenting symptoms, said Jennifer Hanrahan, DO, associate professor of medicine at Case Western Reserve University in Cleveland, during a session at Hospital Medicine 2014 in Las Vegas in March.

Fever from an infection often presents with night sweats and weight loss, even if the patient has an appetite. Those symptoms aren’t usually seen in a patient whose fever has a rheumatological cause instead, he or she is more likely to present with arthralgias, myalgias, and fatigue. Feverish cancer patients, meanwhile, may have night sweats and weight loss but are also more likely to have pain and lack of appetite, she said.

These simple distinctions, and a few other rules of thumb, can take you a long way toward FUO diagnosis, Dr. Hanrahan said.

Patient information: See related handout on fever of unknown origin in adults, written by the authors of this article.

Fever of unknown origin in adults poses one of the greatest diagnostic challenges in medicine. For a large proportion of patients presenting with FUO in higher-income countries, a cause is never identified, and many cases are due to atypical presentations of common illnesses rather than rare disorders.1,2 The lack of a standard diagnostic workup leads to frustration for physicians and patients, and numerous noninvasive and invasive procedures are often performed without arriving at a definitive diagnosis.1,3 Currently, the most widely accepted definition of FUO requires only a clinically documented temperature of 101°F or higher on several occasions and an unrevealing diagnostic workup.2,4 Previous definitions have provided suggested minimal time frames for investigation however, these were acknowledged to be arbitrary and are not included in the current consensus definition.2,4

Physicochemical Changes During Hyperglycemia: Effects On The Immune System

An Approach to Fever of Unknown Origin (FUO)

Rheological Properties and Blood Viscosity

Rheological properties of blood may impact function, metabolism, motility and even the latency for clearing toxins of blood cells . Changes in rheological conditions have been reported during diabetes and hyperglycemia, which may alter red blood cells physiology and the local microcirculation . Indeed, some of the blood rheological properties that have been reported to be disturbed during hyperglycemia and/or diabetes include: an increment in serum osmolarity erythrocyte deformation that is produced by glycosylation of membrane proteins changes in pH and an increase in blood viscosity . All these alterations may impair the immune system activity and could explain the impact that glycemia has on the clinical outcome .

To round off and complete the above rheological scenario, it is to be noted that the concentration of fibrinogen and globulins are also important factors involved in blood viscosity . In fact, an increase in plasma fibrinogen in diabetic patients is a determining factor for blood viscosity . This, in turn, will alter oxygen supply resulting in an impaired immune response.

pH

Other important alterations induced by hyperglycemia in the circulatory system are related to a miss-functionality of the enzymatic machinery of blood cells, including Na+/K+-ATPase activity and glucose-6-phosphate dehydrogenase .

What Are Medical Treatments For Diabetes

An Approach to Fever of Unknown Origin (FUO)

Treatment of diabetes is highly individualized. Treatment depends on the specific type of diabetes, co-existing medical problems, presence of diabetes-related complications, and the physical and mental skills of the affected person.

  • A health care team helps set healthy and feasible goals for lifestyle changes, blood sugar control, and treatment.
  • Together, the affected person and his or her health care team formulate a plan to help meet these goals.

Education about diabetes and its treatment is essential.

  • At the initial diagnosis of diabetes, the health care team will spend much time educating the patient about the condition, treatment, and practical skills for daily self-care.
  • The diabetes care team includes the health care professional and support staff. A professional dietitian and a diabetes educator are usually part of the team. The team may include specialists in hormone health , foot care , neurology, kidney diseases , eye diseases , and behavioral health .
  • Among reputable sources, the National Institute of Diabetes and Digestive and Kidney Disease provides information on diabetes and related research including clinical trials.

The health care team will encounter the patient at appropriate intervals to monitor progress and evaluate goals.

Type 1 diabetes treatments

Treatment of T1D involves multiple daily injections of insulin or continuous insulin delivery by a pump. Daily injections usually combine short-acting insulin and a long-acting insulin .

Medical Definition Of Fever Of Unknown Origin

Reviewed on 3/29/2021

Fever of unknown origin: The presence of fever greater than 38.3’C ‘off and on’ for more than three weeks without a specific cause identified for the fever. Abbreviated FUO. Extensive diagnostic testing can determine the cause in the majority of cases of FUO. FUO may be related to infections such as HIV or other viral infections, cancers, or chronic inflammatory diseases such as sarcoidosis.

Enhancing Healthcare Team Outcomes

In modern medicine, FUO remains one of the most challenging diagnoses as it can be caused by over 200 neoplastic, infectious, inflammatory, and miscellaneous disorders. Diagnosing FUO requires a thorough history, repeated physical examinations, and selective diagnostic testing. Providers should avoid taking a shot-gun approach early in the FUO workup as it can be misleading. Directed diagnostic testing based on a patient’s history and physical is more likely to yield a diagnosis and is more cost-effective.

An interdisciplinary approach is important while pursuing work-up for FUO. It is important to communicate the importance of monitoring fevers without treatment when appropriate with nursing staff to evaluate fever curves and guide additional testing. Primary care providers and hospitalists should work together with specialists to ensure early diagnosis and treatment. Discussing the case with the pharmacy can also be beneficial in determining whether any medications the patient is taking can be causing drug-induced fevers.

Fever Of Unknown Origin

, MD, FACP, Charles E. Schmidt College of Medicine, Florida Atlantic University

Fever of unknown origin is body temperature 38.3° C rectally that does not result from transient and self-limited illness, rapidly fatal illness, or disorders with clear-cut localizing symptoms or signs or with abnormalities on common tests such as chest x-ray, urinalysis, or blood cultures.

FUO is currently classified into 4 distinct categories:

  • Classic FUO: Fever for > 3 weeks with no identified cause after 3 days of hospital evaluation or 3 outpatient visits

  • Health careassociated FUO: Fever in hospitalized patients receiving acute care and with no infection present or incubating at admission if the diagnosis remains uncertain after 3 days of appropriate evaluation

  • or > 3 days in inpatients with confirmed HIV infection if the diagnosis remains uncertain after appropriate evaluation

Is It Possible To Prevent Diabetes

Fever of Unknown Origin (FUO)

No approach has yet been approved by the FDA to prevent T1D, though recent research showed promising results for teplizumab for some at highest risk of developing T1D.

T2D can be prevented in some cases.

  • Control weight to normal or near-normal levels by eating a healthy low-fat, high-fiber diet with appropriate content of calories.
  • Regular physical activity is essential to prevent T2D.
  • Keep alcohol consumption low.
  • Quit smoking and other tobacco products.
  • To control high blood fat levels or high blood pressure, take medications as directed.
  • Lifestyle modifications and/or certain medications can sometimes prevent progression of prediabetes to T2D. Prediabetes can be diagnosed by checking fasting glucose or two hours after ingesting up to 75 grams of glucose .

If you or someone you know has any type of diabetes, focus on preventing diabetes-related complications. Complications can cause serious disabilities, such as blindness, kidney failure requiring dialysis, amputation, or even death.

Are There Home Remedies For Diabetes

If a person has diabetes, healthful lifestyle choices in diet, exercise, sleep, and other habits will help improve glycemic control and prevent or minimize complications from diabetes.

Diabetes diet

A healthy diet is key to controlling blood sugar levels and preventing diabetes complications.

  • Patients who are obese and have had difficulty losing weight on their own should talk to a health care professional. He or she can recommend a dietitian, help set feasible goals, or supervise a weight-modification program.
  • Eat a consistent, well-balanced diet high in fiber, low in saturated fat, low in concentrated sweets, and eliminate excess calories.
  • A consistent diet includes roughly the same number of calories at predictably similar times of day. Such a disciplined diet helps match the correct dose of insulin or other medications.
  • A healthy diet helps keep the blood sugar level relatively even. A healthy, predictable diet avoids excessively low or high blood sugar levels, which can be dangerous and even life-threatening.

Exercise

In any form, regular exercise helps reduce the risk of developing diabetes. Activity can reduce the risk of developing diabetes-related complications such as heart disease, stroke, kidney failure, blindness, and leg ulcers.

Alcohol use

Smoking

Self-monitored blood glucose

Check blood sugar levels frequently, then record the results in a logbook or digital record. At a minimum, check blood sugar before meals and at bedtime.

Concepts On The Origin Of Diabetes

Type 1 diabetes mellitus results from progressive destruction of the insulin producing beta cells in the islets of Langerhans. This disease most frequently occurs in persons of European descent and is less common in other racial groups. The incidence ranges from a low of 12 per 100,000 per year in Japan to as high as 40 per 100,000 per year in Finland . In the United States, the prevalence of type 1 diabetes mellitus by the age of 20 is about 1.7 cases per 1,000 people and the overall annual incidence is approximately 18 new cases per 100,000 people younger than 20. The risk of developing type 1 diabetes before age 20 is approximately 0.5% . The incidence appears to be age-dependent with increase occurring from birth to a first peak around puberty. A second peak in the onset of the disease is noted in those in their 20s to 30s. This later presentation of type 1 diabetes appears to have the same pathogenic origin as in the earlier presentation. Pathogenesis in type 1 diabetes mellitus differs from type 2 diabetes mellitus in that there is actual deficiency of insulin whereas in type 2 diabetes mellitus it is insulin resistance that plays the fundamental role .Continue reading > >

How Did The Patient Develop An Fuo

Fever of Unknown Origin (FUO) with Dr. Raghuram

Epidemiology of FUOs varies according to the category. A comprehensive history and physical examination are cornerstone. By geographic region its been described that in western countries, compared with other regions of the world, infections are less frequent, and inflammatory causes more common. In low and middle-income countries, enteric diseases , brucellosis, tuberculosis, endocarditis, and intra-abdominal abscesses are the most commonly reported infectious causes of FUO.

Giant cell arteritis, also known as temporal arteritis, affects Caucasians , older than 50 years. This diagnosis could be 17% of FUO in older adults.

The most common malignancies implicated in FUO that should be careful considered are lymphoma, hypernephroma, pre-leukemia, and atrial mixoma. Lymphomas, particularly non-Hodgkin are more frequent in HIV patients.

When considering an infectious cause of FUO, history must include:

Previous infectious illnesses

Similar illness in others with similar exposure

Residence and country of origin

Recent travel

Physical examination should pay special attention into the eyes, skin, nodes, liver and spleen.

Eyes: Fundoscopic findings such as Roth spots, cytoid bodies, retinal hemorrhages

Heart: Relative bradycardia, murmur.

Can A Simple Fever Be That Bad For A Diabetes Patient

No doubt youve heard the advice, Drink plenty of fluids, for a fever. This is because fever causes considerable fluid loss through the skin as perspiration. Your loss of fluid can be difficult to estimate, so your physician may want to assume that youd require 12 more quarts of fluid daily than youd normally need. Ordinarily, a mild fever helps to destroy the infectious agent that caused the fever. The tendency to sleep out fever may also be beneficial.

For a diabetic, however, the somnolence that you experience with fever may discourage you from checking your blood sugar, covering with insulin, drinking adequate fluid, and calling your physician every few hours. If you dont have someone awaken you every 20 minutes, you should use aspirin, acetaminophen , or ibuprofen , in accordance with your doctors instructions, to help fight the fever. Beware, however, that aspirin can cause false positive readings on tests for urinary ketones, so dont even test for ketones if you are using aspirin. Never use aspirin or ibuprofen for fever in children because of the risk of Reyes syndrome. Excessive doses of aspirin or NSAIDs can cause severe hypoglycemia. If at all possible, try not to use NSAIDs, as the combination of these drugs with dehydration can cause kidney failure. Acetaminophen can be highly toxic if used in doses greater than those indicated on the package label.
