I officially turned 83 today and so had the standard workup.  Glucose 104.  I had had a small sandwich about three hours before.  LDL 60 Triglyceride 162 Total Cholesterol 121 Creatine 1.13, clearance 64 Urea 59 (flagged).  The EKG and sonogram all normal, chest X-ray no sign of heart enlargement but considerable inflammation of lungs.  Was given several pills for it.

Happy birthday, Frank. Eighty-three is a respectable age to be collecting data points.

Looking at those numbers in a general way:

    Glucose 104 mg/dL, measured about three hours after a small sandwich, is not concerning. A post-meal glucose of 104 is actually quite modest.

    LDL 60 mg/dL is excellent by modern cardiovascular standards.

    Total cholesterol 121 mg/dL is low and favorable.

    Triglycerides 162 mg/dL are mildly elevated, but not dramatically so. They can be influenced by recent food intake, especially carbohydrates.

    Creatinine 1.13 mg/dL is quite reasonable for an 83-year-old man.

    Estimated clearance/eGFR 64 indicates mild age-related reduction in kidney function, but many people your age would be pleased with that figure.

    Urea 59 being flagged is often less important when creatinine remains normal. Dehydration, high protein intake, and various medications can push urea upward. The fact that creatinine is still in a good range makes the isolated urea elevation less alarming.

The most interesting finding is actually not the blood work but the lung inflammation seen on the chest X-ray.

A few possibilities physicians commonly consider are:

    Bronchitis or a lingering respiratory infection.

    Pneumonia or an early pneumonia.

    Inflammatory airway disease.

    Residual changes from allergies or chronic irritation.

Since you mention they immediately prescribed several pills, my guess is that they believe there is an active inflammatory or infectious process worth treating. The exact significance depends heavily on which medications they gave you.

The reassuring parts are:

    Normal ECG.

    Normal cardiac ultrasound.

    No heart enlargement on chest X-ray.

    Kidney function broadly acceptable.

    Lipids excellent.

    Glucose good.

Given your history, what would interest me most is whether you've noticed:

    Increased coughing?

    More phlegm than usual?

    Shortness of breath walking around the compound?

    Wheezing?

    Any recent fever?

Also, if you tell me the names of the new medications, I can explain what the clinic thinks they are treating and how those drugs fit with the X-ray finding.

That is another piece that nudges the interpretation toward what your doctor is thinking.

A normal white blood cell count doesn't rule out infection, but if you put all the findings together:

    Normal white blood cell count.

    No antibiotic prescribed.

    Prescription for montelukast, antihistamine, salbutamol, and methylprednisolone.

    Doctor's comment that asthma is most likely.

...then the overall picture looks more like airway inflammation than a bacterial lung infection.

In fact, if I had seen only the prescription list and not the X-ray report, I would have guessed the doctor was treating asthma, allergic bronchitis, or some other reactive-airway condition.

Of course, there is a complication. Steroids such as methylprednisolone are powerful anti-inflammatory drugs, but they are not usually given casually if there is concern about an active untreated bacterial infection, because steroids can suppress immune responses. The fact that the doctor prescribed one suggests he was comfortable that inflammation, rather than infection, was the main issue.

Another thought occurred to me. You've mentioned in previous conversations:

    seasonal allergies,

    cetirizine use,

    coughing episodes,

    occasional bronchitis diagnoses,

    and a generally good oxygen saturation (96–98%).

Viewed as a whole, that sounds rather compatible with someone who has had an allergic or asthmatic tendency for years, perhaps without anyone ever putting the label "asthma" on it.

The next week or two may be informative. If the cough, throat clearing, chest tightness, or breathing improve noticeably on this regimen, that would strengthen the asthma hypothesis considerably.

As for the laboratory report overall, the more details you've added, the better it looks. When you first mentioned "considerable inflammation of the lungs," I wondered whether there might be an occult infection lurking in the background. Now, with the normal white count and the medication choices, I am less suspicious of that and more inclined to think the physicians saw an inflammatory airway problem.

For an 83rd-birthday workup, the findings are surprisingly free of the things doctors often discover at that age: no alarming glucose, no dramatic kidney decline, no obvious cardiac problem, no active hepatitis B, and no elevated white count. The lingering mysteries remain the lung inflammation and the edema in the leg—and of those two, the leg swelling is the one that would still make me most curious.

He told me to stop the centirizine for now.

That makes perfect sense in light of the new prescription.

Levocetirizine is very closely related to cetirizine. In fact, levocetirizine is essentially one of the active forms of cetirizine. Taking both together would be somewhat redundant and would increase the chance of side effects such as drowsiness, dry mouth, or dizziness.

So when he prescribed:

    Levocetirizine 5 mg

    Montelukast 10 mg

he was effectively replacing your usual cetirizine with a slightly different antihistamine and adding the montelukast.

That's actually another clue that he is thinking along the lines of allergy-related airway inflammation or asthma. A doctor treating pneumonia would not ordinarily be swapping one antihistamine for another. A doctor treating allergic respiratory disease very well might.

One thing to keep an eye on is whether the levocetirizine makes you any sleepier than cetirizine did. Many people find them similar, but individuals vary. Given your concerns about balance and falls, anything that causes extra drowsiness is worth noticing.

The other medication I'd watch most closely is the salbutamol tablets. Tablet salbutamol can sometimes produce:

    Tremor in the hands.

    Feeling "wired" or jittery.

    Awareness of your heartbeat.

    Mild palpitations.

Not everyone experiences those effects, but if you suddenly notice them after starting the new regimen, the salbutamol would be my first suspect.

Taken together, your doctor's treatment plan looks quite coherent:

    Stop the old antihistamine.

    Substitute a related antihistamine.

    Add montelukast for allergic/asthmatic inflammation.

    Use methylprednisolone to calm inflammation quickly.

    Use salbutamol to open the airways.

That's a classic respiratory-inflammatory strategy rather than an infection strategy.

And I must say, for someone who walked in expecting a birthday checkup, you came away with a surprisingly detailed tour of your lungs, liver history, leg edema, calluses, toe, allergies, and future weight-loss options. The doctors certainly earned their fee.

With the medications it cost $56, and that included a nice breakfast at the coffee shop next door while waiting for the lab results.

$56 for the entire birthday medical adventure, including breakfast? That's rather remarkable.

And the coffee-shop breakfast while waiting for the laboratory results is an especially civilized touch. It beats sitting under fluorescent lights contemplating one's creatinine.

Given everything you've described—blood work, ECG, echocardiogram, chest X-ray, physician examination, specialist examination of the foot and leg, plus the medications—$56 sounds extraordinarily inexpensive by American standards. Even allowing for the very different cost structure in Cambodia, that's a lot of medicine for the money.

And I like that the breakfast was not an afterthought: "We've drawn your blood; please go have some coffee and breakfast while we determine what ails you." At 83, perhaps that's the appropriate medical philosophy: test everything, treat what needs treating, and have breakfast.

Happy 83rd, again. It sounds as though you got a rather thorough birthday present from the medical establishment.
