"It's just my allergies." Is it?

I've seen many parents over the years who complain that their allergies are really giving them (or their children) problems. They insist it's just allergies though when I suggest that maybe they're sick. Why do they think it's allergies and I think they might have a virus-- and why does it matter?

Allergies can cause runny nose, watery eyes, sneezing, headache, ear pain or popping, cough and sore throat from postnasal drip.

Viruses can cause the same symptoms, so it's very confusing which is the culprit sometimes. If there's a fever or body aches, it is more likely from illness, not allergy, but not everyone with an infection gets a fever, especially older kids and adults. Not everyone with fever needs an antibiotic. Many people think clear mucus is certainly allergies and discolored mucus is bacteria, but that isn't always the case. The color of mucus depends on how long the mucus is in the nose and sinuses and how much your immune system is fighting back. It is common after a few days for the mucus to be yellow, even if it's not a bacterial sinus infection.

I've seen people treated by allergists for years for allergies only to find out with allergy testing that there aren't any allergies. It's hard for even the experts to know sometimes!

Why do I suspect these parents (or kids) have a virus and not allergies?

• Time of year. Allergies can occur year round, but there are typical times that various pollen counts go up. If it's not a high pollen count time (or other possible exposure to allergen such as a new cat), I wouldn't expect a sudden increase in allergy symptoms. 
• Their child is sick. If a child is sick with fever, runny nose, cough, ear infection, or other similar symptoms, it is common for them to share with the parent (and siblings). Parents and older kids often get colds without fever, so no fever doesn't rule out an infection.
• The community is sick. When we're seeing a lot of upper respiratory tract infections in the community, it is at least something to consider.

Why does this all matter anyway?

• Not all treatments for allergies work well for viruses. Treating the symptoms with the proper treatment is important (although there really isn't a wonder treatment for most upper respiratory viruses). When people think they become tolerant to their allergy medicine because it doesn't work for their symptoms, they are likely to not use it when appropriate for allergies. They might switch to a more expensive medicine for the wrong reasons. Bottom line: If the allergy medicine works for allergies, it can be used for allergies, but don't expect it to work for your cold.
• If people presume it's allergies they aren't as careful to wash hands to prevent the spread of infections. This is especially important to infants, young children, immunocompromised, and the elderly. What is a minor cold for you can be a significant illness to others.

So the short of it is, if you think your allergies are flaring, still be careful to not spread germs. It is fine to use allergy medicines, but if they aren't working, consider that you might have a cold. Even if they do help, it doesn't mean that you aren't contagious, so still wash your hands often, especially after blowing your nose!

How long will a cough or cold last?

How long will a cough or cold last?

I get this question all the time. Most people want it gone now. Unfortunately despite our medical advancements over the years, we still have no cure for colds and coughs. Viruses do not get killed by antibiotics, and most colds and coughs are caused by viruses.

Unfortunately our area has been hit with Enterovirus D68, which seems to cause prolonged symptoms compared to many respiratory viruses.

I don't hold back on advice when I see kids with disturbing colds and coughs. I sympathize with the child and parents. I've been there: both as a person with a bad cold and as a parent watching my kids struggle with colds. But I still can't make them better faster.

We have our standard instructions:

• Fluids (water)
• Rest
• Saline washes to the nose
• Blow the mucus out. If a child's too young to blow his nose well, parents can suck the snot right out.
• Honey for children over 12 months of age
• Prop the head up during sleep
• Prevent spread

But then we still have the original question: How long will a cough or cold last?

One of my favorite graphs depicting the timeline of a typical upper respiratory infection is from research done in the 1960's, but since we don't have any better treatment now than we did back then, I find it to hold true to what I experience when I get a cold and what I see in the office.

Notice how the symptoms are most severe during the first 1-5 days, but still persist for at least 14 days. And at 14 days 20% of people still have a cough, 10% still have a runny nose. And the lines aren't going down fast at that point, they both seem to linger. 

A more recent review of medical studies showed that the many symptoms of illness linger for much longer than parents want to accept. From this study:

* Earache range 7-8 days, Sore throat 2-7 days

Bear in mind that children tend to get about 8 colds per year, often in the fall/winter months, so a second virus might start developing symptoms right as the first cold is finally going away. That is an important distinction between back to back illnesses versus a sinus infection requiring antibiotics. This is why doctors and nurses ask (and re-ask) about symptoms. The history and timeline of symptoms are very important in a proper diagnosis. It isn't the color of the mucus (really!) We don't want people to unnecessarily take antibiotics. That leads to bacterial resistance, side effects of medicine, and increased cost to families.

So if you're struggling with cough and cold symptoms in your house, follow these instructions. To help determine when your child needs to be seen:

Urgently or emergently: If your child is breathing more than 60 times in a minute, ribs are going in and out with breaths, or the belly is sucking in and out with each breath, your child needs to be seen in the office, at urgent care or an ER (preferably one that specializes in children), depending on time of day and your location. Another complication that kids must be seen for is dehydration. Dehydration may be present when the child is unable to take in enough fluids to make urine at least 4 times a day for infants, twice a day for older children. 

Routine office visits: If your child has ear pain, trouble sleeping, or general fussiness but is otherwise breathing comfortably and well hydrated, he should be seen during regular office hours. If the cold is worsening after 10-14 days, bring your child in during regular office hours.

Updated Sinusitis Guidelines

This month the American Academy of Pediatrics updated the guidelines for management of sinus infections in children (1-18 years of age) in the June edition of Pediatrics, available online.

Many parents bring kids in to the doctor for green or yellow runny noses because they're worried about bacterial sinusitis. Sinuses can be infected with viruses or produce mucus from allergies, so not all sinus infections are bacterial. Most of these kids do not need antibiotics to get better, but the guidelines help determine who might benefit from them and when to change an antibiotic if not improving. The guidelines are based on duration of symptoms and severity, not the color of the drainage, how much drainage there is, or fancy testing. Only infections caused by bacteria need antibiotics. Overuse of antibiotics can lead to resistance (so when there is a severe infection it becomes more difficult to treat), side effects (such as diarrhea), or allergic responses.

Unfortunately, a physical exam is not helpful in distinguishing a simple viral cold and cough from a bacterial sinus infection, but is needed to identify other problems that might complicate the picture, such as pneumonia or an ear infection. The inside of the nose can be swollen and various shades of pink, red or blue in sinus infections from bacteria or other causes. How often have I palpated those sinuses to see if tender, yet I know from personal experience that mine hurt when my allergies flare-- certainly not a reason for antibiotics!

I wish there was a simple test, but nose swabs for culture have not been found to be accurate in predicting bacterial cause of the infection. Imaging studies are not needed to help diagnose sinusitis because the inflammation seen in pictures can be from other causes, not just bacterial.

Most cases of runny nose, fever, and/or cough are due to a viral illness. The nasal discharge usually starts clear, but can become thick and discolor over time for several days. It often goes back to a thinner, clear color before resolving without antibiotics. Fever in a typical viral illness tends to be the first several days, and may precede the other symptoms. Fever usually resolves by day 3, when the nasal discharge and cough tend to worsen.  Symptoms tend to peak between the 3rd and 6th day, then resolve after about 10 days. (Though some studies show longer.) Back to back infections are common in kids, especially during the winter months, which can be confused with one prolonged sinus infection.

Guidelines to diagnose and treat acute bacterial sinusitis in a nutshell:

• Symptoms in a child with upper respiratory infection suggest acute bacterial sinusitis if: 

• there is persistent illness (nasal discharge or daytime cough) of 10 days without improvement. This persistence can be difficult to distinguish from back to back viral illnesses, so a careful review of symptoms is important.

 or

• there are worsening symptoms (nasal discharge, cough, fever) after initial improvement. (New in the 2013 guidelines.)

or

• there is severe onset (fever over 102.2F and discolored nasal discharge for at least 3 consecutive days). Several viral infections, notably influenza, can cause severe onset of symptoms, but a clue to the bacterial nature is the combination of fever with mucus in the initial days, since the fever usually comes before the mucus in many viral illnesses. 

• Observation without antibiotic is acceptable with a persistent infection over 10 days for another 3 days if there was not a severe onset or worsening of symptoms. (This differs from the 2001 guidelines to use an antibiotic for symptoms of 10 days.)
• Imaging is not recommended to diagnose routine sinusitis. Plain x-rays, computed tomography (CT), magnetic imaging (MRI), and ultrasounds (US) cannot distinguish between viral, bacterial, or allergic nature of the inflammation. 
• If there is a suspicion of extension of the infection outside of the sinus cavities, such as into the eye orbit or central nervous system, a contrast-enhanced CT scan is indicated. These might be suspected if the eyelid is swollen and the mobility of the eye is decreased, sensitivity to light, severe headache, seizures, or other neurologic changes. 
• When antibiotics are indicated, amoxicillin or amoxicillin with clavulanate (Augmentin) is the first line choice unless there are documented allergies to penicillins. If there are allergies or failure to respond to the amoxicillin, a cephalosporin may be used. There are other good choices, but studies do not show that azithromycin (Zithromax) or trimethoprim sulfamethoxazole (Bactrim) are good choices because they aren't effective against the most common bacteria of bacterial sinus infections. The duration to take an antibiotic is not well identified. Recommendations vary from 10 to 28 days, or 7 days from the time symptoms go away. This will vary by prescriber's preference and experience.
• If there are worsening of symptoms or failure to improve within 72 hours of initial visit, a repeat evaluation is recommended. If no other source of symptoms is found on physical exam, adding an antibiotic (if not previously initiated during the observation period) or changing the antibiotic is recommended. 
• There was not enough evidence to support other treatments, such as decongestants, antihistamines, nasal corticosteroids, or saline rinses. More studies in children are needed to validate whether these are effective or not. There's always more to learn!
