The clinic visit the diabetes team needs to work to together with the person with diabetes to review the program of care including the management goals and targets at each visit [19] medicine park oklahoma order combivent 100 mcg otc. It is important that the person with diabetes shares in any decisions about treatment or care as this improves the chance of jointly agreed goals being adopted following the consultation symptoms cervical cancer cheap combivent 100mcg line. A family member medicine 7253 cheap combivent 100 mcg free shipping, friend or carer should be encouraged to attend the clinic to help them stay abreast of developments in diabetes care and help the person with diabetes make informed judgments about diabetes care treatment 99213 discount combivent 100 mcg without a prescription. An important goal of diabetes management is to prevent the microvascular and macrovascular complications of diabetes without inducing iatrogenic side effects. This involves active management of hyperglycemia together with a multifaceted approach targeting other cardiovascular risk factors. Glycemic management Enquiries and discussions should be made about hyperglycemic symptoms, problems with medications, including issues relating to injections, hypoglycemia and self-monitoring of blood glucose. Hyperglycemic symptoms Symptoms relating to hyperglycemia usually occur when the blood glucose rises above the renal threshold leading to an osmotic diuresis. Medications the diabetes care team is responsible for ensuring that the person with diabetes has access to the medication and equipment necessary for diabetes control. In many countries this is available free or at a reduced rate; many people with diabetes may be unaware of this and timely advice may alleviate some of the anxieties about the cost of diabetes. Oral hypoglycemic drugs Each of the oral hypoglycemic drugs has its strengths and profile of side effects (see Chapter 29) and these should be discussed. Assessment of glucose control Supporting the person with diabetes to achieve excellent glycemic control is an essential component of diabetes care. The methods of assessing glucose control essentially involve short-term measures such as self-monitoring of blood glucose and long-term measures such as glycated hemoglobin (see Chapter 25). Not all those with diabetes will undertake self-monitoring of blood glucose, but when they do it is incumbent on the health care professional to discuss the findings with the person with diabetes and how these will affect future management. The glycated hemoglobin provides a further measure of the adequacy of glycemic control and sometimes there may be a discrepancy between this measure and self-monitored blood glucose. It is important to explore the reasons that underlie the differences, which may range from biologic issues such as genetically determined rates of glycation, through to inappropriately timed glucose readings to fabricated results. A pristine sheet (with no blood stains from fingersticks) and with the use of a single pen color may be a clue to the latter. The use of computers and the ability to download results may help to observe patterns of hyperglycemia, although it is important to make sure that the meter has not been shared. It is clearly important that people with diabetes are encouraged to tell the truth. Sometimes clinicians can appear judgmental which may result in people with diabetes falsifying their results because they are scared. They can feel as if some clinicians are headteachers and they do not want to be reprimanded. It is understandable why someone would not put themselves through that if they did not have to . It is better to break down these barriers and to build a relationship whereby the person with diabetes feels that it does not benefit them to lie, and that the health care professional is there to support, not to judge. Despite these targets, many people with diabetes are unable to achieve this level of control. It is important for the health care professional to explore the reasons with the person with diabetes why the control is not ideal. A common limiting factor in the ability to achieve good control is hypoglycemia which is one of the most uncomfortable, inconvenient and feared side effects of diabetes medication (see Chapter 33). An exploration of the underlying causes and advice about prevention are required for the future. When a person with diabetes is treated with insulin, it is important to ensure that they carry a readily accessible source of glucose such as glucose tablets. Concentrated glucose solution and glucagon should also be made available for use in more severe hypoglycemia. As these treatments may only be used infrequently, it is worth checking whether they are in date. Furthermore, as they need to be administered by another individual, it is important to ensure that the friends and relatives of the person with diabetes know how to administer them before they are needed. In some instances, the only way of avoiding disabling hypoglycemia is to accept a lesser degree of glycemic control.

It is estimated that essential hypertension accounts for about 10% of cases in people with diabetes medicine wheel colors cheap combivent 100 mcg free shipping. Finally treatment abbreviation discount combivent 100mcg mastercard, insulin may stimulate the proliferation of vascular smooth muscle cells symptoms xeroderma pigmentosum cheap combivent 100mcg with amex, which could lead to medial hypertrophy and increased peripheral resistance [22 medications pain pills buy combivent 100mcg free shipping,25]. The association may be partly genetically determined: subjects with diabetes and microalbuminuria commonly have parents with hypertension and may also inherit overactivity of the cell-membrane Na+­H+ pump (indicated by increased Na+­Li+ counter-transport in red blood cells), 660 Cardiovascular Risk Factors Chapter 40 which would tend to raise intracellular Na+ concentrations and thus increase vascular smooth muscle tone [27]. The basic mechanisms of hypertension include decreased Na+ excretion with Na+ and water retention. Peripheral resistance is increased, to which raised intracellular Na+ will contribute. These discrepancies may be explained by differences in diet, treatment, metabolic control and the type and duration of diabetes. Patients with microalbuminuria who are insulin-resistant appear to be particularly susceptible to hypertension [30]. The deleterious effects of hypertension on left ventricular function are also accentuated by the presence of diabetes. Screening for hypertension in diabetes As the two conditions are so commonly associated, people with diabetes must be regularly screened for hypertension and vice versa. Hypertensive patients, especially if obese or receiving treatment with potentially diabetogenic drugs, should be screened for diabetes at diagnosis and during follow-up. Should hyperglycemia be detected, potentially diabetogenic antihypertensive drugs should be reduced or changed to others or used in combinations that do not impair glucose tolerance, and normoglycemia can then often be restored. This is especially important in those with other cardiovascular risk factors, such as nephropathy (which is associated with a substantial increase in the cardiovascular mortality rate), obesity, dyslipidemia, smoking or poor glycemic control. Impact of hypertension in diabetes A large proportion of hypertensive people with diabetes show signs of cardiovascular aging and target-organ damage [10]. Marked postural hypotension, which can coexist with supine hypertension, may indicate the need to change or reduce antihypertensive medication, especially if symptoms are provoked.

Vaccaro, paper presented at the 26th Annual Meeting of the European Diabetes Epidemiology Group, Lund, 1991. Various other expert bodies have suggested alternative, generally lower target levels (Figure 40. Investigation of hypertension in diabetes Initial investigation of the hypertensive patient with diabetes aims to exclude rare causes of secondary hypertension (Table 40. A standard 12-lead electrocardiogram may show obvious ischemia, arrhythmia or left ventricular hypertro662 phy; the latter is more accurately demonstrated by echocardiography, which will also reveal left ventricular dysfunction and decreased ejection fraction. Exercise testing (or stress-echo) testing and 24-hour Holter monitoring may also be appropriate. A fresh urine sample should be tested for microalbuminuria (see Chapter 37) and another examined microscopically for red and white blood cells, casts, and other signs of renal disease. Further specialist investigations that may be needed include an isotope renogram and other tests for renal artery stenosis (Figure 40.

This means weight reduction or weight stabilization in the obese, sodium restriction, diet modification and regular physical exercise (moderate intensity, 40­60 minutes, 2­3 times weekly). Dietary intake of saturated fat has been associated with impaired in insulin sensitivity and should therefore be reduced [37]. Alcohol should be restricted to 2­3 units/day in men and 2 units/day in women, but omitted altogether if hypertension proves difficult to control. Smoking causes an acute increase in blood pressure and greater variability overall [38]. Smoking cessation is especially important, as smoking not only accelerates the progression of atherosclerosis and vascular aging, but also impairs insulin sensitivity [39] and worsens albuminuria [40].

Management Although some patients initially respond to sulfonylureas treatment chlamydia purchase 100mcg combivent, most ultimately need insulin [76] symptoms with twins order combivent 100 mcg line. In addition to controlling diabetes symptoms copd purchase discount combivent online, insulin also improves body weight and pulmonary and pancreatic function [71,77,78]. Starting from adolescence, all patients with cystic fibrosis should be regularly screened for diabetes using the oral glucose tolerance test or serial measurements of HbA1c [78]. Dietary modification in patients with cystic fibrosis who also have diabetes presents much the same difficulties as in patients with chronic pancreatitis. Oral pancreatic enzyme therapy helps to improve nutrient digestion and absorption. Fibrosing colonopathy is a concern in patients receiving higher strengths of lipase [79]. Conclusions Although rare, diabetes secondary to pancreatic disease is potentially important. The underlying pancreatic disease may need treatment in its own right, while disorders with a genetic basis must be identified so that other family members can be screened. Suggestive symptoms include features of pancreatic disease (steatorrhea, unexplained weight loss or back pain) and severe and brittle diabetes in the absence of a family history of diabetes.

Introduction Diabetes has long since taken over from syphilis as the great imitator, and nowhere is this more apparent than in the wide variation of possible modes of initial presentation. The classic triad of thirst, polydipsia and polyuria accounts for only a modest proportion of new diagnoses of diabetes. Ketoacidosis and hyperosmolar hyperglycemic syndrome may precipitate a dramatic presentation to emergency services. Non-specific symptoms including tiredness, general malaise and repeated or persistent skin infections may lead to a biochemical diagnosis of diabetes. Regrettably, the nature of the condition is such as to allow it to remain asymptomatic for years, allowing the clinical presentation to be a long-term complication of diabetes. This could be in the form of macrovascular disease (myocardial infarction, stroke, black toe) or in the form of microvascular disease (loss of visual acuity, neuropathy).

The first report of successful pregnancies following a renal transplant was in 1986 [247] treatment naive definition generic combivent 100 mcg with visa. Successful pregnancies following a transplant are now common [248] medications quizlet buy cheap combivent 100mcg line, with three large registries providing pregnancy outcome data symptoms 6 days before period due discount combivent 100 mcg without prescription. Among 176 renal transplant recipients medicine gif order 100mcg combivent otc, pregnancy was not associated with any long-term adverse effect on the transplant. When the pre-pregnancy serum creatinine was >150 mol/L, however, there was a tendency for the serum creatinine to be higher postpartum. Approximately half of the births occurred before 37 weeks, with a mean gestation of 35. Hypertension occurred in 60­80%, with pre-eclampsia diagnosed in approximately one-third, although this may be over-reported as the diagnosis of pre-clampsia is difficult in women with preexisting hypertension, renal impairment and proteinuria. The Toronto Renal Transplant Program is one of the few studies to report follow-up data on 32 children born to renal transplant recipients. Postnatal growth was normal although developmental assessment showed one child had moderate to severe sensorineural hearing loss, another a learning disability and a third a pervasive developmental disorder [250]. It is likely in the future that more women with diabetic nephropathy will have a combined pancreas­kidney transplant before a planned pregnancy. The benefit and risk of a combined pancreas­kidney transplant over a single kidney transplant has not yet been evaluated for pregnancy. The antenatal population is becoming more obese, reflecting the secular trend in obesity. It has a major impact on maternal and fetal health as well as on health services and resources [261]. Babies of obese mothers are more likely to have birth weight above the 90th percentile [266] and be at risk of birth trauma and adult obesity and diabetes [267]. The first report linking pre-gestational weight and malformations in South Wales between 1964 and 1966 found that mothers of anencephalic infants were significantly heavier than a matched control group [268]. Data from 22 951 pregnant women enrolled in a prospective cohort study reported that major non-chromosomal congenital defects associated with diabetes were more common in obese women [270]. Thyroid function should be monitored in pregnant women with hypothyroidism as small increases in thyroxine replacement are frequently 899 Part 10 Diabetes in Special Groups required [272]. This is important as there is some evidence linking mild degrees of hypothyroidism in the first trimester with adverse neurodevelopment [273]. The simultaneous ingestion of iron and thyroxine may inhibit thyroxine absorption, and women should be advised to take any iron supplements at least 2 hours after or before taking thyroxine [274]. Women with a previous history of Graves disease will also need their thyroid function measured before and during pregnancy. Fetal monitoring is also recommended as maternal thyroid-stimulating antibodies can cross the placenta causing transient fetal and neonatal hyperthyroidism [275]. Clinical management Pre-pregnancy care Pregnancy care for women with diabetes should begin prior to conception when glycemic control can be optimized, medication reviewed and folic acid started. All health care providers who look after women with diabetes should emphasize the benefits of prepregnancy planning and good glycemic control on pregnancy outcomes and encourage women to plan their pregnancies and to engage in pre-pregnancy care. Discussions about contraception and pregnancy plans should form part of the ongoing care of all pre-menopausal women with diabetes. Once a woman expresses an interest in becoming pregnant she should have access to a pre-pregnancy clinic where specific pre-conceptual advice can be given. Women who seek out and engage in pre-pregnancy care tend to have higher educational and economic status and greater family and social support [281,282]. A survey in New Zealand showed 60% of non-pregnant women with diabetes aged 18­40 years would like more information about diabetes and pregnancy [283], suggesting there is an unmet need for good pre-pregnancy advice. It remains a clinical challenge to increase the awareness and uptake of pre-pregnancy care for all women with diabetes planning pregnancy, especially among more hard to reach groups. Information to cover during pre-pregnancy care All pre-pregnancy advice should be supported by evidence of its benefit in pregnancy.
