Advice when GP Calls

I am having a phone call from my GP to discuss my latest blood tests and I think he might try and Fob me off .

I have recently had my B12 loading doses and know that my levels have risen from 185 to 1227 so I know that he will say that is Ok as expected.

What I don't understand is that my folate level after the B12 loading has gone down from 3.1 to 2.3. Is this normal to do that after the B12 loading.

Also my ferritin levels have increased from 17.6 to 21,4. This is the highest it has been for the last 15+ years.

I also have had a rash on the back of my neck and generally feel exhausted after the loading doses of B12

I think he will say that the levels are ok and wait to see my New Gastro Consultant but this might not be for a while. Any Advice please

Hi,I had a lot of problems with my GP.

Consultant said that he thought I was developing pernicious anaemia and as my grandmother had had it, it was quite likely. He advised GP to give me B12 injections.... But GP didn't think my levels were low enough 125....

Anyway long story short, the whole thing was upsetting and stressful.

In the end I requested an Intrinsic factor test which proved I had PA. Now I'm not sure what that test is actually called it may have a technical name and I am sure someone on here will be able to tell you.

I can only say keep on at them, I know it's tiring, but you have to for your own sake!

Best wishes

Anti-Intrinsic factor antibody test ( IFab, IFA ). This test is to look for an antibody that targets the intrinsic factor (IF) required for the body to absorb B12 from food (which is the extrinsic factor).

The BCSH (haematologists) say that if this test proves positive it is 95% certain you have pernicious anaemia. BUT also say that it is only positive in 40-60% of cases -so a negative result cannot rule out pernicious anaemia. So, positive is PA, negative still might be !

Martyn Hooper, who is the founder of the Pernicious Anaemia Society had the test three times before getting a positive result. Someone with only one chance at this might decide that this is not the test for them because a GP might use a negative result to prove that the patient does not have PA- in spite of (or ignorance of) what BCSH have to say !

As long as the doc doesn't try to tell you that you are cured and no longer need injection, but keeps on on regular jabs it should be OK.

Folate does vary quite a bit from day to day. If I were you I would get supermarket folic acid pills (400 mcg) and take one a day.

Hi, it is normal for B12 levels to go up high after loading injections- over 2000 isn’t unusual. Drs shouldn’t check levels again- don’t let them stop future jabs. The B12 needs folate to work properly. I would look at a good B complex- methylated is preferable. If not enough folate in mix (400mcg) then take one separately too.

Your ferritin is still too low. You would appear to not be absorbing nutrients properly. Improving digestion is a start - digestive aid /herbal bitters before every meal.

The whole point of loading dose is to rapidly boost your depleted B12, and then once B12 replete, the maintenance injections are administered at a frequency which will keep you from deteriorating again.

So unless there is a dietary reason for your initial low level, which after loading can then be treated by eating more B12-rich foods or by tablets, there seems no reason to stop the injections -or to measure them again in your bloodstream.

If you have pernicious anaemia, you will always have pernicious anaemia. Even if your B12 level is over the measurable amount (usually 2000 ng/L). There is no cure, and so B12 injections will be required for life. You will usually get injections at a frequency of 2-3 months.

There are some other reasons for a low B12 level, and the symptoms will be exactly the same - those of B12 deficiency - but some causes can be cured. Like small intestine bacterial overgrowth (SIBO) which can be treated with antibiotics, sometimes needing quite a few courses to eradicate.

If your GP does not think you have PA, what does he think is the reason for your B12 deficiency ? How has he ruled out PA as the cause ? If he hasn't, then why would he stop treatment ? These are all fair questions, if it really is his intention to stop your injections.

Do you have any neurological symptoms ? In this case, injections should continue, every other day, until no more improvement can be gained - and only then maintenance injections every 2 months. Nerve damage can take a while to repair, and if left, some damage may remain. If not treated at all, neurological symptoms can worsen.

I had bowel cancer and a right hemicolectomy and have been diagnosed with Bile Acid Malabsorption. I was under a gastroenterologist who was sure he knew it was SIBO but because I could not tolerate the anti biotics he has transferred me to a regional specialist centre for further investigation. Before doing that he sorted the B12 loading and wanted the GP to sort out my Vitamin D levels but I can not tolerate oral medicine so he tried me on Baby Vitamin Drops but I came out in a rash at the back of my neck. Because this was straight after the B12 injections He is unsure and stopping the Vitamin D drops. He is banking on the Gastroenterologist The GP has put the B12 on every 3 months for life

I'm not medically trained but hope some of the info below will be of interest.

I've assumed you're in UK.

Some links below may have details that could be upsetting.

Link about "What to do next" if B12 deficiency suspected or newly diagnosed

b12deficiency.info/what-to-...

Symptoms of B12 Deficiency

Symptoms of Peripheral Neuropathy (damage to peripheral nerves)

nhs.uk/conditions/periphera...

Peripheral neuropathy can be associated with B12 deficiency and sometimes with folate deficiency.

Risk Factors for PA and B12 Deficiency

b12deficiency.info/who-is-a...

Unhappy with Treatment (UK info)?

Letters to GPs about B12 deficiency

b12deficiency.info/b12-writ...

Point 1 is about being under treated for B12 deficiency with neuro symptoms.

Point 5 is about being symptomatic for B12 deficiency with an in range serum b12 result.

The link has letter templates on a variety of situations linked to B12 deficiency that people can base their own letters on.

Letters avoid face to face confrontation with GP and allow patient time to express their concerns effectively.

Best to keep letters as brief, to the point and polite as possible. It's harder to ignore a letter in my opinion.

CAB NHS Complaints

citizensadvice.org.uk/healt...

Might be worth talking to local MP if struggling to get treatment.

Retention of UK medical records

bma.org.uk/advice-and-suppo...

Don't rely on there being evidence of a past diagnosis of PA (Pernicious Anaemia) or other cause of B12 deficiency in current medical records.

If you get proof of diagnosis eg positive test result/letter from specialist confirming diagnosis etc keep a copy in a safe place. You may need it in the future.

Accessing Health Records (England)

patients-association.org.uk...

bma.org.uk/media/1868/bma-a...

In UK, patients can register to access test results/health records online. Should be details on GP surgery website.

UK B12 documents

BSH Cobalamin and Folate Guidelines

b-s-h.org.uk/guidelines/gui...

Summary of above document

pernicious-anaemia-society....

BMJ B12 article

bmj.com/content/349/bmj.g5226

Emphasises need to treat patients who are symptomatic even if their B12 level is within range.

BNF Cyanocobalamin

bnf.nice.org.uk/drug/cyanoc...

BNF Hydroxycobalamin

bnf.nice.org.uk/drug/hydrox...

See section on "neurological involvement" in above link if you have neuro symptoms.

NICE CKS B12 and Folate Deficiency

cks.nice.org.uk/anaemia-b12...

cks.nice.org.uk/topics/anae...

Local Guidelines

Each CCG/Health Board/NHS Hospital Trust in UK will have its own local guidelines on treatment/diagnosis of B12

I suggest you track down the guidelines on treatment/diagnosis of B12 deficiency for your area of UK and compare them with BSH,NICE CKS and BNF links above .

Some areas of UK have guidelines that can be unhelpful. See blog post below.

b12deficiency.info/blog/202...

PAS can offer support and info on PA.

PAS (Pernicious Anaemia Society)

Based in Wales, UK. Has some members in other countries.

pernicious-anaemia-society....

There is a helpline number that PAS members can ring and an online contact form.

PA tests

Intrinsic Factor Antibody (IFA) test

labtestsonline.org/tests/in...

Parietal Cell Antibody (PCA) test

labtestsonline.org/tests/pa...

PCA is not recommended as a diagnostic test for PA in UK.

It is still possible to have PA with a negative result in IFA or PCA test but sadly some doctors may be unaware that it is possible to have Antibody Negative Pernicious Anaemia.

About 50% of people with PA test negative on IFA test.

About 10% of people with PA test negative on PCA test.

B12 books I found useful

"What You Need to Know About Pernicious Anaemia and B12 Deficiency" by Martyn Hooper

Martyn Hooper is the chair of PAS (Pernicious Anaemia Society). BNF treatment in book is out of date. See BNF link in this reply.

"Living with Pernicious Anaemia and Vitamin B12 Deficiency" by Martyn Hooper

Has several case studies.

"Could it Be B12?: An Epidemic of Misdiagnoses" by Sally Pacholok and JJ. Stuart (US authors)

Very comprehensive with lots of case studies.

"Vitamin B12 deficiency in Clinical Practice" (subtitle "Doctor, you gave me my life back!" by Dr Joseph Alexander "Chandy" Kayyalackakom and Hugo Minney PhD

Copies of above books may be available from local library services.

Vital to get adequate treatment or there is an increased risk of permanent neurological damage including problems with spinal cord.

May be worth drawing doctor's attention to this possibility in any letter or conversation if patient has concerns that they are being under treated.

Neurological Consequences of B12 Deficiency

PAS news item

pernicious-anaemia-society....

PAS article about SACD, sub acute combined degeneration of the spinal cord

pernicious-anaemia-society....

B12 article from Mayo Clinic in US

ncbi.nlm.nih.gov/pmc/articl...

Table 1 in above article is about frequent misconceptions about B12 deficiency.

Testing B12 during treatment

In UK, national guidance suggests that testing B12 levels after treatment has started is irrelevant. See links below.

Referrals

Has your GP/doctor got a list of all of your symptoms especially any neuro symptoms and symptoms affecting your spinal area? See links to symptoms lists up page.

If neuro symptoms present, has your doctor

1) referred you to a neurologist?

2) referred you to a haematologist?

Some UK forum members who cannot get treatment from NHS or whose level of NHS treatment is not enough to keep symptoms at bay, resort to self treatment using B12 ampoules sourced from Europe and some use private GPs.

I've written some very detailed replies with more B12 info eg more B12 articles, b12 websites etc
