BMJ Publishing House ( Summer/ 2006) ------Outpatient Tx in DM2 *********

Total Daily Dose(TDD) in Physiologic Insulin Replacement Therapy= Wt in Kg x 0.7= __Units of Insulin daily.

Basal & Bolus Insulin Requirements/ 24 hrs: 50 % Basal ( Detemir, Glargine);    50% Bolus ( Aspart, Glulisine, Lispro)..

For Post-Meal ( PP) Hyperglycemia: 1700/ TDD=X ( i.e., 1 Unit of Analog Insulin will decrease X mg/dl of Blood Glucose). Target correction 'to' not lesser than 150 mg/ dl, to avoid Hypoglycemia.

To prevent PP Hypoglycemia, based on the amount of Carbohydrate ingested:   450/ TDD=Y ( i.e, 1 Unit of fast-acting Insulin analog will cover the consumption of Y gms of carbohydrate).

1. Data have shown that inpatient mortality in patients with previously undiagnosed diabetes was:

Answer: >15%
Newly discovered hyperglycemia was associated with a higher in-hospital mortality rate (16%) compared with patients with a history of diabetes (3%) and patients with normoglycemia (1.7%; both P < .01).

2. Of the following choices, 3-BG is a highly accurate indicator of blood glucose control for surgery patients that:

Answer: Averages discrete 24 measurements over 3 perioperative days
It is shown that 3-BG is a highly accurate indicator of blood glucose control for surgery patients that averages discrete 24 measurements over 3 perioperative days. It is measured starting on the day of surgery and the first 2 postoperative days. Blood is taken by arterial line drop, venous line drop, or capillary fingerstick methods.

3. According to data from the Portland Diabetic Project, the major risk factor for increased morbidity and mortality in cardiac surgery with diabetes is:

Answer: 3-BG
According to data from the Portland Diabetic Project, the major risk factor for increased morbidity and mortality in cardiac surgery with diabetes is 3-BG. They found that mortality was 4.4% among those with 3-BG greater than 200 mg/dl compared with 1.6% in those with 3-BG less than 200 mg/dl.

4. Use of GIK infusions to control blood glucose is no longer recommended because:

Answer: All of the above
GIK infusions to control blood glucose are no longer recommended because it is burdensome and it is difficult to control glucose especially in patients who are eating. Additionally, studies with GIK are complicated by varying degrees of glucose control, congestive heart volume, and volume of GIK infusion.

5. One of the key elements of continuous insulin infusion is:

Answer: Blood glucose must be controlled for all 3-BG to normalize the risk for surgery patients with diabetes
Researchers have found that duration of CII therapy matters and there is independent significance of daily glucose parameters on outcomes.

6. Diabetes increases acute MI mortality risk by about:

Answer: 50%
Diabetes increases acute MI mortality risk by about 50%.

7. Compared to subcutaneous insulin, continuous insulin infusion has been shown to reduce CABG mortality by:

Answer: 65%
Compared to subcutaneous insulin, continuous insulin infusion has been shown to reduce CABG mortality by 65%.

8. According to the ADA, the in-hospital target for glucose is:

Answer: FPG 90-130 mg/dL; peak postprandial <180 mg/dL
According to the ADA, the in-hospital target for glucose is FPG 90-130 mg/dL and <180 mg/dL peak postprandial.

9. What is the threshold for starting an insulin drip?

Answer: FPG 140 mg/dL
The threshold for starting an insulin drip is an FPG of 140 mg/dL.

10. For patients with diabetes and major surgery or NPO status, the recommended therapy for control blood glucose is:

Answer: Continuous variable rate IV insulin drip
For patients with diabetes and major surgery or NPO status, the recommended therapy to control blood glucose is continuous variable rate IV insulin drip. The starting rate can be determined by using the following formula: U/h = (BG ¨C 60) x 0.02 where BG is current BG and 0.02 is the multiplier. Glucose should be checked every hour and the drip adjusted. The multiplier should also be adjusted to keep blood glucose in desired target range (80-110 mg/dL in the ICU and 100-140 mg/dL on the floor).

11. When do you convert to SC basal from IV drip insulin?

Answer: When >0.5 units/hr IV insulin is required and glucose is in a stable range
IV drip insulin can be converted to subcutaneous basal insulin if > 0.5 U/hr of IV insulin is required with normal blood glucose. In this case, a long-acting insulin such as glargine can be initiated. However, if there is no prior DM and normal A1C, the patient may not need SC insulin. The SC insulin must be started at least 1 to 2 hours before stopping IV insulin.

12. IV drip insulin can be converted to subcutaneous basal insulin if more than 0.5 U/h of IV insulin is required with normal blood glucose. In this case, a long-acting insulin such as glargine can be initiated. However, if there is no prior DM and normal A1C, the patient may not need SC insulin. The SC insulin must be started at least 1 to 2 hours before stopping IV insulin.

Answer: All of the above
When converting to SC insulin, it is important to establish the 24-hour insulin requirement. Half the insulin should be given as basal and half should be given as total bolus.

13. A preferred SC insulin therapy in the hospital for a patient eating discrete meals uses:

Answer: About 50% basal insulin (glargine) and 50% rapid-acting insulin (glulisine/lispro/aspart)
A preferred SC insulin therapy in the hospital for a patient eating discrete meals uses about 50% basal insulin (glargine) and 50% rapid-acting insulin (glulisine/lispro/aspart).

14. During preadmission, it is recommended that oral agents are discontinued and the dose of basal insulin is modified as needed.

Answer: True
For patients with diabetes and major surgery or NPO status it is recommended that oral agents are discontinued and the dose of basal insulin is modified. The recommended therapy to control blood glucose is continuous variable rate IV insulin drip. Glucose should be checked every hour and the drip adjusted. The multiplier should also be adjusted to keep blood glucose in desired target range (80-110 mg/dl in the ICU and 100-140 mg/dl on floor).

15. Scheduled insulin analogs are preferred over sliding scale because they improve glycemic control without increasing the risk of hypoglycemia.

Answer: True
Scheduled insulin analogs are preferred over sliding scale for patients with diabetes and major surgery or NPO status, the recommended therapy to control blood glucose is continuous variable rate IV insulin drip. The starting rate can be determined by using the following formula: U/h = (BG ¨C 60) x 0.02 where BG is current BG and 0.02 is the multiplier. Glucose should be checked every hour and the drip adjusted. The multiplier should also be adjusted to keep blood glucose in desired target range (80-110 mg/dl in the ICU and 100-140 mg/dl on floor).

Persons who have type 2 diabetes and whose glucose exceeds 200 mg/dL have at least a 30% decrease in survival within 200 days.

http://www.medscape.com/viewarticle/536351_5

(The best results came when you continued the rosiglitazone and you gave a 25 mg dose of Aldactone. So, that is something we can use).

http://www.medscape.com/viewarticle/536351_7

(...Do triamterene or amiloride work for edema caused by TZDs? Well, it turns out that triamterene is great if you want stones. Then you're finished. What is meant is that triamterene does very little. For some reason there is a rash of triamterene use and you could end up doing is switching patients to a thiazide diuretic and get miraculous blood pressure discoveries. Don't use triamterene. Amiloride is very good. Amiloride will work because, in fact, the epithelial sodium channel (EnaC) is the one that has been found to really be affected by the TZDs. So amiloride would be an excellent drug to use in combination; something like Moduretic (amiloride) would be brilliant in people on TZDs because you'd have the thiazide plus the amiloride working. Spironolactone is also very good, but if you've got issues with potassium or something and the patient has good enough kidney function, then Moduretic would probably be a better way to go. The loop diuretics are worthless, and they are not going to help you in that situation.
The other little thing in terms of edema in these patients, especially if they're susceptible, is if you start dosing the TZD slowly rather than blasting patients with 8 mg up front, you'll tend to get less edema than you will if you start at much higher doses early on).

(...What drugs are safe to use for diabetes treatment in people with chronic kidney disease stage III or beyond? You can't use metformin anymore. Sulfonylureas are no longer that safe because many are renally excreted and would lead to prolonged activity and hyperglycemia would be a risk. Insulin is the safest. It is a natural product, so remember that short-acting insulin becomes long-acting; long-acting becomes longer-acting. Dosage modification becomes critical.

Some of the newer agents like the secretagogue marketed as Starlix, whose pharmacologic name is nateglinide, are neutral in the setting of renal failure. Even in dialyzed patients, its pharmacokinetics are unaltered, so its secretion is by nonrenal mechanisms. Rosiglitazone, a TZD, can be used up to a certain stage in renal failure; we still have the ability to use it because it is not nephrotoxic. It does not accumulate like metformin does, and there is no toxicologic concern.

So there are agents that can be used, but we have insulin, at least some insulin onboard to hedge our bets, to make sure the A1c control is on target. But there are some oral agents, the ones that have been mentioned, that can be used in renal failure).

(...How many of the patients given Aldactone (spironolactone) developed hyperkalemia?   Researchers used 25 mg, which is much lower than doses they use in cirrhosis of the liver and other conditions where we do not see a lot of hyperkalemia. Aldactone is used a lot in hirsute patients in whom you need to block androgen receptors -- the polycystic ovary population. We use up to 100 mg/day and hyperkalemia as a limiting problem.

In KD, you do not need to use high doses. In fact, 12.5 to 25 mg is more than adequate. Use a loop diuretic twice a day, if you USE them. As for tolerability, generally don't even blink until the potassium hits 5.8. If you do all that, hyperkalemia will be an issue, but it will not be a big issue in those patients).

(...What is the best treatment to prevent progression of diabetic neuropathy? The best treatment is glucose control. The Diabetes Control and Complications Trial (DCCT) showed 60% reduction in the rate of new-onset neuropathy, and 70% in progression of preexisting neuropathy.

All of the marketed drugs for "neuropathy" don't address the fundamental biology of the process. They block pain through projection from the dorsal column in the gracile bundle in the thalamic integration site. It is similar to the way Tylenol (acetaminophen) makes your headache go away, where you think you do not have that brain-based process. Tylenol resets the membrane potential for pain threshold, but the process is still there.
So do not really prescribe Neurontin (gabapentin) or any of those pain medications that are supposed to heal the nerves. They do not heal nerves. Glycemic control and then in the future when we have nerve growth factor based approaches or aldose reductase based approaches, but right now glycemic control is the winning move here).

(...A question here about the "negative effects" of thiazide diuretics on lipids and insulin resistance, and should those effects discourage their use in people with diabetes. The short answer is no, it should not discourage the use because every single person with diabetes is volume expanded, period, and you will not be able to unload them unless you put them on peritoneal dialysis when their glomerular filtration rate is 65. It's just not going to happen.

You need to be using the diuretics, and unfortunately, it was thought that the angiotensin-converting enzyme (ACE) inhibitors and the angiotensin-receptor blockers (ARBs) would protect you from the effects of the diuretics on metabolic control, but there is a paper in the Journal of the American Medical Association that -- in a very nicely controlled study looking at a number of things, including insulin levels and oral glucose tolerance tests, etc. -- actually probably does not support that theory.

This does not mean that if you have a patient with diabetes that you should avoid diuretics. Absolutely the contrary. They need to be used. You may need to go up on the diabetes medicine. You may need to reinforce lifestyle more. But you absolutely are going to have to use them. The key issue is to make sure the potassium doesn't go below 4. As long as the potassium stays above 4, you will be in good shape. Once it starts going below 4, you actually are starting to worsen insulin sensitivity, and in addition to that, by the way, you're going to see negative results because if a patient has hypokalemia, you are actually closing the potassium channels and worsening blood pressure independent of anything else. Minoxidil works in the exact opposite manner).

The initial dose of rapid-acting insulin may be calculated as 1 U of rapid-acting insulin for every 10 g of carbohydrate eaten plus an additional 1 U for every 30 mg/dL above the target self-monitoring blood glucose level of 100 mg/dL.

A GOOD LUNCH HAS ATLEAST 250 CALS OR 30 GMS OF CARBOHYDRATE.

Administer from one third to one half of that as basal insulin, and the remainder as rapid-acting insulin, distributed as 40% (8 U) at breakfast, 30% (6 U) at lunch, and 30% (6U) at supper. Consider adopting a carbohydrate-counting program to refine the premeal doses.

1. Which one of the following statements is correct?

Answer: Type 2 diabetes is characterized by progressive loss of beta-cell function
Although insulin resistance is another feature of type 2 diabetes, it has not been shown to worsen over time. In clinical trials with a treat-to-target approach, near normalization of fasting glucose levels in patients inadequately controlled on oral agents by the addition of basal insulin will result in A1C levels of ¡Ü 7% in 60% of patients. Data from the UKPDS estimated that a 1% decrease in A1C would lead to a 25% risk reduction in the development of complications in subjects with type 2 diabetes.

2. Common reasons cited by providers as barriers to insulin initiation include all of the following except:

Answer: Fear that insulin use may promote injection drug use among patients
Concern about the promotion of injection drug use has not been cited by providers as a reason for failure to initiate insulin treatment in surveys.

3. The current American Diabetes Association (ADA) guidelines for goals of therapy in type 2 diabetes are as follows:

Answer: Preprandial blood glucose 90-130 mg/dL and peak postprandial blood glucose < 180 mg/dL
Current ADA guidelines are fasting blood glucose of 90-130 mg/dL and peak postprandial blood glucose < 180 mg/dL.

4. Mr. Smith, a 62-year-old mechanic with type 2 diabetes, is seen for routine follow-up. He is currently on glyburide 10 mg twice daily, metformin 850 mg twice daily, and rosiglitazone 4 mg once daily. His A1C at this appointment is 8.6%, and it has steadily increased over the last 2 visits. Review of his log reveals fasting glucose levels of 160-220 mg/dL and 2-hour postprandial values between 160 and 200 mg/dL. Which one of the following methods will best help Mr. Smith improve his glycemic control?

Answer: Add 1 injection of 10 U of insulin glargine at night to the current regimen and adjust to target fasting blood glucose levels
The most effective means of achieving a target A1C would be to add glargine insulin to his regimen. Addition of detemir or NPH would be equally effective. Lispro would not be effective for basal insulin coverage because it is a rapid-acting insulin.

5. Which one of the following statements in regard to rapid-acting insulin analogs is correct?

Answer: They rapidly dissociate into monomers after injection
Rapid-acting analogs begin to act within 25 minutes of subcutaneous injection and are taken right before meals. They rapidly dissociate into monomers and are quickly absorbed into the circulation. Duration of action is 4-5 hours.

6. According to an analysis of the 1999-2000 National Health and Nutrition Examination Survey (NHANES), the number of Americans with diabetes who have A1C levels < 7% is estimated to be:

Answer: 37%
Data from NHANES 1999-2000 revealed that only 37% of patients with diabetes achieved A1C levels < 7%, and 37.2% had A1C levels > 8%.

7. The following are contraindications to use of inhaled insulin except:

Answer: History of hypoglycemia with subcutaneous insulin use
Even though hypoglycemia is an adverse effect that can be seen with use of inhaled insulin (and all other insulin preparations), it is not a contraindication.

8. Which one of the following statements is true about the Treat-to-Target Trial, which randomized type 2 diabetes patients failing oral antiglycemic drugs (OAD) to the addition of NPH or glargine?

Answer: Glargine + OAD therapy was associated with fewer hypoglycemic events
Glargine and NPH were equally effective in terms of reduction in A1C level achieved and the percentage of subjects who achieved an A1C concentration of < 7%.

9. Which one of the following statements best describes normal endogenous insulin secretion?

Answer: Continuous pulsatile secretion at low levels with increased bursts of secretion with meals
Insulin is secreted continuously at low levels (basal secretion) coupled with increased bursts of secretion during mealtime.

10. All of the following scenarios are indications for the initiation of insulin in type 2 diabetes except:

Answer: A patient with a history of type 2 diabetes for 10 years with an A1C level of 7.2% treated with metformin 500 mg twice daily
Insulin therapy is indicated for pregnant women, newly diagnosed symptomatic patients with very high blood glucose levels, and those whose A1C level remains above goal on maximal oral therapy. Insulin therapy is not indicated for this patient because even though the patient may have had diabetes for a long time, he/she has relatively good control with lifestyle intervention and monotherapy. Intensification of therapy can be achieved by adding a second OAD.

http://www.medscape.com/viewarticle/545155

1. Which one of the following medications must be given by injection?

Answer: Exenatide
As with many small polypeptides, exenatide can only be given by injection.

2. What is the mode of action of metformin?

Answer: Suppression of hepatic glucose production
The mechanism of action of metformin is via suppression of hepatic glucose production. The mechanism of action of the sulfonylureas is stimulation of insulin secretion by the pancreas. The mechanism of action of the short-acting insulin secretagogues is stimulation of prandial increases in insulin. The mode of action of the thiazolidinediones (TZDs) is the suppression of hepatic glucose production.

3. Which one of the following statements is true?

Answer: Imaging data have shown a reduction in visceral fat with TZD treatment
Imaging data have shown a reduction in visceral fat with TZD treatment. However, exenatide has been not been shown to have beta-cell protective effects in clinical trials; there are no head-to-head comparisons of the lipid effects of metformin, the TZDs, and exenatide; and 20% of patients receiving exenatide experience nausea.

4. What is the Third Report of the National Cholesterol Education Program (NCEP III) and American Diabetes Association (ADA) low-density lipoprotein cholesterol (LDL-C) target in patients with type 2 diabetes and no overt cardiovascular disease?

Answer: Less than 100 mg/dL
The NCEP II and ADA LDL-C target in patients with type 2 diabetes and no overt cardiovascular disease is 100 mg/dL.

5. Maximal doses of metformin will reduce glycated hemoglobin (A1C) levels by approximately what range?

Answer: 0.9% to 1.4%
Maximal doses of metformin will reduce A1C levels by approximately 0.9% to 1.4%.

( Medsite CME/ Pulmonology/6-13-06----Pub Date) ----COPD/ Role of Anti Inflammatory Meds

1. The estimated annual cost of chronic obstructive pulmonary disease (COPD) in the United States in 2002 was:

Answer: 32.1 billion dollars
The estimated annual cost of COPD in the United States in 2002 was 32.1 billion dollars. This figure was calculated by adding the 18 billion dollars spent in hospitals (direct cost) and 14.1 billion dollars spent indirectly (lost productivity/morbidity) due to the diagnosis and/or exacerbations of COPD. Overall, the chronic diseases asthma, diabetes, heart disease, and hypertensive disease cost the United States over 270 billion dollars in combined direct and indirect fees. Asthma cost 5.8 and 5.1 billion dollars in direct and indirect costs, diabetes cost 91.8 and 31.8 billion, heart disease cost 72 and 20.6 billion, and hypertensive disease figures were 5.5 and 7.2 billion in direct and indirect costs, respectively.

2. Studies show that most COPD patients often decrease their activity levels because of:

Answer: Dyspnea
COPD patients decrease their activity as a result of the unpleasant sensation of dyspnea and, as a result, become deconditioned, which leads to further impairment in exercise tolerance because of the high oxygen requirements of deconditioned muscles. As the effects on the lungs progress, dyspnea will become present with minimal effort or even at rest. Ultimately, quality of life will deteriorate to the point at which patients may become oxygen-dependent and finally completely immobilized.

3. At every patient visit, beginning with school-aged children, a __________should be recorded along with vital signs by the office staff.

Answer: Smoking history
At every patient visit, beginning with school-aged children, a smoking history should be recorded along with vital signs by the office staff. This history should include the number of cigarettes smoked per day, duration of smoking habit, exposure to passive smoking, and an estimate of total pack-years of smoking. Expanding the vital signs to include smoking status is a low-cost intervention that has been shown to increase the rate of identifying former or current smokers.

4. The hallmark of COPD is a decline in FEV1 to less than _______ of predicted, with relative preservation of the FVC.

Answer: 80%
The hallmark of COPD is a decline in FEV₁ to less than 80% of predicted, with relative preservation of the FVC. An FEV₁/FVC ratio of less than 70% of predicted identifies obstructive impairment. A normal FEV₁ and a normal FEV₁/FVC ratio usually exclude the diagnosis of COPD. While measurement of FEV₁ can determine the severity and staging of COPD, peak expiratory flow rate (PEF) is a less accurate gauge. A normal PEF does not exclude mild COPD. In general, this measurement underestimates the severity of COPD.

5. Clinical goals for the treatment of COPD include:

Answer: All of the above
The clinical goals in COPD treatment listed in the Workshop Report, Global Strategy for Diagnosis, Management, and Prevention of COPD -- 2005 Update include: symptom relief, increased exercise tolerance, improved health status, preventing and treating exacerbations, decreased mortality and/or prolonged survival, preventing and treating complications, and minimized treatment-adverse effects.

6. A patient who presents with an FEV₁ less than 80% with or without symptoms would be classified under the Global Obstructive Lung Disease (GOLD Initiative as:

Answer: GOLD Stage I: mild COPD
A patient who presents with an FEV₁ less than 80% with or without symptoms would be classified under the GOLD Initiative as GOLD Stage I: mild. The classification criteria are: GOLD Stage 0: at risk for COPD -- Chronic symptoms, exposure to risk factors, normal spirometry; GOLD Stage I: mild COPD - FEV₁ less than 80% with or without symptoms; GOLD Stage II: moderate COPD - FEV₁ 50% to 79%, with or without symptoms; GOLD Stage III: severe COPD - FEV₁ 30% to 49%, with or without symptoms; and GOLD Stage IV: very severe COPD - FEV₁ < 30% or presence of chronic respiratory failure or right heart failure.

Proposed Spirometry-Based Severity Classification System for COPD

http://www.medscape.com/viewarticle/549962 ( COPD Tx):

Severity Postbronchodilator FEV₁/FVC FEV₁ % Predicted

Mild </= 0.7 >/= 80

Moderate </= 0.7 50-80

Severe </= 0.7 30-50

Very severe </= 0.7 < 30

Table 2. Stepped Therapy of COPD

Stage Characteristics Recommended Therapy

All Avoidance of risk factors
Influenza vaccination

I: Mild COPD FEV₁/FVC < 0.70 and
FEV₁ >/= 80% predicted
with or without symptoms Short-acting bronchodilator when needed
Active reduction of risk factor(s)
Influenza vaccination

II: Moderate COPD FEV₁/FVC < 0.70 and
>/= 50% < FEV₁ < 80% predicted change to FEV₁ (between 50% and 80% predicted) Short-acting bronchodilator when needed
Active reduction of risk factor(s)
Influenza vaccination
Add regular treatment with 1 or more bronchodilators (when needed)
Add rehabilitation

III: Severe COPD FEV₁/FVC < 0.70 and >/= 30%
< FEV₁ < 50% predicted Short-acting bronchodilator when needed
Active reduction of risk factor(s)
Influenza vaccination
Add regular treatment with >/= 1 bronchodilators (when needed)
Add rehabilitation
Add inhaled glucocorticoids if repeated exacerbations

IV: Very Severe FEV₁/FVC < 0.70
FEV₁ < 30% predicted or presence of respiratory or right heart failure Short-acting bronchodilator when needed
Active reduction of risk factor(s)
Influenza vaccination
Add regular treatment with >/= 1 bronchodilators (when needed)
Add rehabilitation
Add long-term oxygen therapy if chronic respiratory failure is present
Consider surgery
Add inhaled glucocorticoids if repeated exacerbations

Using classically established criteria, Figure 2 enumerates current indications for LTOT. It is ideal to confirm these criteria during a time of clinical stability. Reassessment of oxygenation status after an exacerbation is recommended, although the optimal timing remains controversial.^[27]

1. According to DHHS and ISA-USA guidelines, antiretroviral treatment should be started immediately for asymptomatic patients who have:

Answer: CD4 cell counts <200 and any viral load
There are several complications of HIV that may be avoided if therapy is started early for patients with low CD4 cell counts. Currently, the guidelines recommend offering and/or considering treatment for patients in the 2 middle groups and deferring treatment for those with CD4 cell counts >350 and viral loads <100,000 copies/mL.

2. Goals of HIV therapy include:

Answer: All of the above
In terms of HIV, the goals are viral suppression and, concomitantly, restoration or preservation of immune function. For patients, improvement in quality of life is the primary goal, as well as reductions in HIV-related morbidity and mortality.

3. It is advised that drug-resistance testing be performed at the first visit for treatment-naïve patients.

Answer: True
Even if treatment is not being initiated immediately, drug-resistance testing can identify primary or transmitted resistance and help in planning therapy.

4. Advantages of NNRTI-based regimens include:

Answer: Fewer drug interactions than with PIs
Resistance to NNRTIs can be conferred by a single mutation or a limited number of mutations, whereas multiple mutations confer resistance to PIs. Additionally, nevirapine has demonstrated hepatotoxicity. On the other hand, NNRTIs have fewer potential drug interactions than do PIs.

5. Potential disadvantages of PI-based regimens include:

Answer: All of the above
Several PI-based regimens may not be taken once daily; hence, adherence is less likely than with once-daily regimens. Also, PIs have documented adverse side effects, and they inhibit the CYP450 isoenzyme, resulting in a high likelihood of increased drug interactions.

6. The antiretroviral agent with a Category D classification in pregnancy is:

Answer: Efavirenz
Efavirenz has teratogenic properties in humans and is contraindicated for women who are pregnant or who may become pregnant.

7. It is acceptable to continue treatment in the presence of antiretroviral failure in the hope that the treatment will eventually be effective.

Answer: False
Continuing treatment in the presence of antiretroviral failure can result in accumulation of drug-resistance mutations, the development of cross-resistance within multiple drug classes, difficulty reestablishing virologic control with future regimens, and eventual decline in T cell counts and disease progression.

8. The criteria for defining treatment failure in antiretroviral-experienced patients include:

Answer: All of the above
Suboptimal viral suppression is a sign, along with virologic rebound after viral suppression, of virologic failure; decreasing CD4 cell counts indicate immunologic failure; and new, recurrent, or worsening AIDS-related opportunistic infections, along with other symptoms, are hallmarks of clinical failure and disease progression.

9. Phenotypic resistance testing can detect changes as small as _________-fold.

Answer: 1½

10. In patients with HIV and hepatitis coinfection, most elevations in aminotransferase levels are severe and permanent.

Answer: False

http://www.medscape.com/viewprogram/6288

1. Which of the following is/are characteristic of PIs but not of NNRTIs?

Answer: High genetic barrier to resistance
Among PI-naive patients treated with boosted PIs, the emergence of resistance is rare, and if it does occur, it typically takes a long time to emerge. In contrast, the risk of dyslipidemia is high with PIs and low with NNRTIs.

2. Data on once-daily treatment of treatment-naive patients can be extrapolated directly to treatment-experienced patients.

Answer: False
With once-daily treatment, trough levels may be lower than with twice-daily treatment. Because treatment-experienced patients may harbor resistance mutations, they may need the consistently higher drug levels seen with twice-daily treatment to maintain viral suppression.

3. The only PI approved for once-daily therapy in a nonboosted regimen is:

Answer: Atazanavir
Currently, fosamprenavir 1400 mg and lopinavir 800 mg are approved for once-daily dosing, but only when boosted with ritonavir 200 mg. Atazanavir 400 mg is approved for once-daily nonboosted administration, and boosted saquinavir (2000/100) is under evaluation for once-daily dosing.

4. If atazanavir is given with tenofovir, it must be boosted.

Answer: True
Tenofovir has been shown to reduce atazanavir levels significantly; therefore, nonboosted atazanavir should not be coadministered with tenofovir to treatment-experienced patients.

5. Factors that can increase pharmacokinetic variability of a drug include:

Answer: All of the above
In addition to the factors listed here, interpatient genetic differences, pregnancy, adherence rates, and drug-drug interactions may increase the pharmacokinetic variability of a drug.

6. The PIs that are least affected by acid-reducing agents are:

Answer: Lopinavir, fosamprenavir, darunavir, and saquinavir
Atazanavir and indinavir require stomach acid for maximal dissolution and absorption, and acid-reducing agents, particularly proton pump inhibitors, produce gastric pH levels above those needed for optimal levels of these PIs. In contrast, the dissolution and absorption of lopinavir, fosamprenavir, darunavir, and saquinavir are minimally affected by acid reduction. The effects of acid-reducing agents on tipranavir and nelfinavir are not fully known.

7. The statin safest to use with PIs is:

Answer: Pravastatin
Pravastatin levels decrease in the presence of PIs, whereas those of atorvastatin, lovastatin, and simvastatin are increased, raising the risk of rhabdomyolysis. Even pravastatin levels are increased by some PIs, notably darunavir; thus, pravastatin and, in some cases, atorvastatin, may be coadministered with PIs, but it is prudent to start with low doses and titrate up gradually.

8. Rifampin can lower PI levels as much as:

Answer: 98%
Rifampin, a very potent cytochrome P450 inducer, has been observed to lower levels of PIs, particularly atazanavir, by as much as 98%. Thus, rifampin should not be used with PIs. Rifabutin, at lower-than-typical doses, may be safe to use with PIs.

9. According to DHHS guidelines, the first thing to do for a treatment-naive patient with chronic HIV is:

Answer: Perform a drug-resistance genotype test
The DHHS recommends resistance testing before therapy is initiated, because increasing numbers of individuals are receiving resistant virus initially, and selection of appropriate therapy is facilitated by the awareness of the presence and type of resistance.

10. The most common reason for increasing viral load in a patient on ART is:

Answer: Poor adherence
Although drug interactions may attenuate the effect of PI therapy, the most common reason for lack of efficacy is patient nonadherence. Only if this is ruled out are other causes likely.
