Dr Marion Sloan and Dietitian Gillian Goddard discuss IBS and its management in primary care:
Webinar session: Microbiome for Beginners
Webinar session: A fresh talk on Iron deficiency Anaemia in primary care
Top Tips
- If the patient is referred back to GP with advice and guidance, any you need to re-refer – send directly to the hospital. The referral does not need to come back through CASES a second time.
- For iron deficiency anaemia, the critical test is ferritin, iron profile is not needed.
- With any symptoms, if it is cancer, it gets worse. Other causes of diarrhoea for example, can get better. If symptoms are improving then sit tight, review, reconsider.
- Calprotectin
- Unreliable if drinking alcohol, on aspirin, ACEi, NSAIDs and PPIs
- Invalidated in PR bleeding.
- Not suitable for over 65s
- Do not do AFP or CEA as diagnostic tests.
- Reflux: trial a PPI BD 1 hour before food, plus acidex advance and famotidine for 8 weeks. Refer for open access gastroscopy if no improvement.
- NAFLD score: https://www.mdcalc.com/calc/3081/nafld-non-alcoholic-fatty-liver-disease-fibrosis-score
Info required: Age, ALT, AST, platelets, albumin, BMI diabetes status.
If low risk: give lifestyle advice
If indeterminate or high risk: refer hepatology for opinion/fibroscan
- Haemochromatosis family screening: request HFE genotyping (if kids underage and parent do not want testing – test spouse- if negative kids will be carriers, if carrier kids could have 50 % chance of being affected. Generally in Haemochromatosis if ferritin >1000 significant liver damage likely present. Tests FBC, ferritin, iron studies. HFE genotyping (paper form to SCH genetics lab – yellow/gold top)
- Hepatitis C: now 95-98% curable with new drugs, much less toxic than previous regimes. Worth revisiting if patients became disengaged. Screen risk groups: (Ex-IVDU, haemophilia, migrants from high risk areas, babyboomers). Refer hepatology if liver damage otherwise infectious diseases
- Bacterial overgrowth: look out for high folate and low B12
- New onset watery diarrhoea and age > 60, check drugs – common causes – lansoprazole, sertraline
- Food bolus or obstruction/choking episode, refer for open access gastroscopy.
