(Panel consisted of Dr Saleem A Rana,Dr Mehboob Ashraf,Dr Arshad Javaid Sh,Dr Liaqat Ali Ch.Choice of questions lied with the panel)



How do family physicians manage Acid Peptic Disease?


Job of primary care physicians is always more difficult than other physicians in one aspect.Illness does not manifest fully during initial days.Investigations are yet not there.Lot of diagnostic tools are missing or yet to be used.This is the setting where primary care physicians are working.Taking all these difficulties in account ,one has to say that job is being done pritty nicely.On the whole there are no major complaints about primary care level.


On the Use of H2 Antagonists and PPIs.Are these being overused?


Where ever these are being prescribed ,there is usually some indication.These are not being overused.


Definition of Acid Peptic Disease.


This term is not of technical nature.Upper G.I symptoms,or upper abdominal pain are more descriptive.All complaints in epigastrium or upper abdomen can be grouped together and then analysed.


Main causes of these symptoms can be described as under.


1 Peptic ulceration consisting of


1.Non Ulcer Dysphagia

  1. IBS

  2. Somatic Complaints of Psychological Diseases.

  3. Acute Pancreatitis

  4. Chronic Pancreatitis

  5. Acute or Chronic Cholecystitis

  6. Malignancy in stomach,liver,biliary tract or pancreas or G I T .


There are many other rare causes.AMI or Acute Pancreatitis are severe emergencies and differential diagnosis should not be difficult when investigations like ECG are taken into account.Dr Arshad Javaid Sh pointed out that many young female patients present with epigastric pain rather than UTI symptoms while investigations reveal UTI as diagnosis.Dr Saleem Rana also supported this experience.PID could be causing lot of confusion if it is there according to Prof Arif Siddiqi.Dr Liaqat proposed that use of NSAIDS and other similar drugs might cause these problems when used for symptoms of UTI.


Diagnostic tools are ,as anywhere else,thorough history and proper examination.Pay special attention to


Alarming Symptoms.

There are certain alarming symptoms which should make all physicians alert to the possibility of some serious situation.These are followings.



Incidence of Psycho-Somatic Illness


More than 50 % of patients in the practice of Prof Arif Siddiqi belong to this group.These patients need very careful handling.They need help certainly.Physicians usually pick up the diagnosis quite early during the history taking.We do know that these patients need reassurance more than anything.But real reassurance comes after only and it is effective only when physician



If reassurance is attempted without these 3 basic steps than it may not succeed.



Relation to Meals of pain from upper G I T.


Pain from stomach,duedenum,oesophagus,pancreas,liver and biliary tract is most of the times related to food.So this aspect in the history should not be given much weight.It shall only be interpreted in the light of general impression.



Peptic Ulcerations



GERD/ Heart Burn


Here patient does not use words meaning pain.Rather some word which depicts feeling of burning is used.This is very important.Than it is mostly in the retrosternal area.Patient points to a wide and vague area above epigastrium.This is worsened after meals.Very small percentage of GERD patients have hiatus hernia.Majority has no such thing.Etiology lies in the transient lower oesophageal valve relaxation.During the relaxation of the valve lower oesophagus is exposed to acid,for which it is not made.So this exposure to acidic pH is the main cause.


Duedenal and Gastric Ulcers


Here words depicting pain are used.Burning is not prominent.Feelings of pain and multiple descriptions for painful feelings rather than burning are presenting symptoms.Patient points to (pointing sign) a small area in epigastrium with the finger rather than moving his fist on chest.


Precipitating factors: Careful and detailed history can identify use of NSAIDS,smoking or use of alcohal as contributing or precipitating factors.


Diagnosis


History and examination can make a good provisional diagnosis.Physician can commit his diagnosis on the basis of history and examination.Confirmation can come only with endoscopy.Even endoscopy will pick up cases if H2 Antagonists and PPIs have not been uses for healing.H2 antagonists can heal in 7 days and PPIs can heal in 3-4 days to the degree where endoscopy can not make diagnosis.Barium Meal studies are no more prefered for this purpose.Even under best circumstances where double contrast medias and techniques of follow through have been undertaken with flouroscopy ,sensitivity is only upto 15-20 %.


Indications for Endoscopy




Acute Pancreatitis/Peptic Ulcer


Diagnosis can be difficult in between these two conditions.Patient with Ac pancreatitis is usually sitting up in the bed,doubling on his epigastrium with the fist pressed against epigastrium.Response to drugs and progress over next 24-48 hours usually decide the diagnosis.Serum amylase and Serum Lipase help in the diagnosis.



Hiatus Hernia and GERD are not Synonimous.


Hiatus hernia can produce GERD.But most of the times it is asymptomatic.Very small percentage of patients of hiatus hernia have GERD and similary very few cases of GERD have hiatus hernia as the cause.Most of the patients of GERD have no hiatus hernia.Barium meal is here as ineffective to pick up the diagnosis as in peptic ulcer.


Enodscopy can diagnose Hiatus Hernia.These are rarely symptomatic.These can be managed with acid inhibitors.As long as patient remains symptom free no surgical option is justified because it requires major surgery.In situations where herniation is quite large and occupies large space in the chest cavity, surgery is mandatory.



Differential Diagnosis of Cholecystits,acute and chronic pancreatitis,IHD,


Only investigations like USG,ECG,serum amylase,serum lipase,CT Scan or MRI can make the final diagnosis.History and examination may give some idea but confirmation is required by investigations.CT Scan and MRI can only diagnsose chronic pancreatitis.Clinician must seek the help of investigations.



Helicobacter Pylori and Duedenal /Gastric Ulcers.


H pylori infection is not related or associated to GERD in etiological role.It is strongly associated with duedenal and gastric ulcers.More than 80 % of these ulcers are associated with the infection of H pylori.It is one of the three definite known causes of peptic ulcer.Other two are



Mode of Infection: Orofaecal

Reinfection: Common

Infection in contacts High incidence in family members

Confirmation of Infection: Serological testing for antibodies

Breath test.(not available in Pakistan)


(Ig G testing confirms one time exposure.If infection has not been eradicated in the past then eradication shall be tried.)


If endoscopy shows gasteritis then H.pylori must be demonstrated in the biopsy before it can be incremented in the eitiology.



Diet:


In patients of GERD


Frequent Small and Dry

Meals should be used to avoid reflex.Water can be used inbetween meals.No water shall be taken during meals.Large hotty meal should be avoided.


Therapy of Peptic Ulcerations.





H2 blockers,Proton Pump Inhibitors


These are remarkabley safe drugs.Occasional headache with H2 inhibitors and severe acute weakness with PPIs have been noticed in practice.Otherwise no important side effects have been observed.PPIs have been licensed to be used continously for one year.

This safety profile is helpful in managing GERD where therapy is almost lifelong with some periodic discontinuations.


H2 Antagonists are metabolized through cytochrome P 450.So these can interact with all drugs which share this pathway.One has to be careful.Pigmentation or fluid retension have been described but are rarely observed.Allergic rash has been seen both with H2 antagonists and PPIs.


Irritable Bowel Syndrome ( IBS).


This is a condition which surfaces in almost all situations.History usually dates back to months or years.Upper G I Symptoms are usually accompanied with some colonic features in IBS.If lower GIT symptoms are lacking then one should not consider IBS in differential diagnosis.Following are the symptoms of lower GIT or Colon.



Management of IBS: Reassurance as described earlier forms more than 50 % of the management.Spasmolytics ,Isabghol Husk,antidepressents from all groups & benzodiazepines in smaller doses are usually helpful.Each individual needs different combinations.

Medicine.


Is yet not pure science. It is a psychosocial scientific discipline. Patient’s satisfaction is essential, may be by drugs or by lip service.


Etiology of Upper GIT Symptoms.


Systemetic approach should be developed about one of the following causes.


Reflux Oesophagitis.



Duedenal Ulcer.


Please remember it is a disease with periodicity. Episodes don’t last longer than 4-6 weeks. Any complaint lasting longer than this period is not duedenal ulcer. If it has to be duedenal ulcer, than it is complicated DUwhich may be due to


Common Indications for Endoscopy.



On Helicobacter Pylori



ON TREATMENT of H Pylori Infection.


His research shows following results in Pakistan.
~30-35% resistence exists against Clarithromycin.
~10-15 % resistence against Metronidazole is present.
~Combination therapy consisting of

Lansoprazole 30 mgs
Metronidazole 400 mgs
Clarithromycin 500 mgs


~BID/ for oneWeek showed success rate of 65 %.


On use of drugs


His important Messages on

ON Hep C


Please be acutely aware of this possibility. Pick up cases as early as possible. Fat intolerence, mild low grade fever off and on or on mild exertion should raise the possibility.


On Pancreatitis


Sub clinical pancreatitis is more common than Ac Pancreatitis is.

Serum amylase is positive in 80 % of cases of Pancreatitis.If combined with Lipase 97 % cases are positive.


On Gastrobiliary Desease

It is on rise. Many more cases of subclinical Pancreatitis are coming up.

Incidence of CA head of Pancreas and Ampulla is increasing.

Pick up cases as early as possible.


On Management of Emergencies in Melena or Hemetemesis.


Please don’t rush them to Lahore unless vital signs are stable. Many patients die on roads.

Practical tips on Acid Peptic disease

by Capt Dr Liaqat Ali Chaudhry.

(From Feb 99 Issue)



Upper GIT symtoms





Following conditions may be kept in list of D/D.


Anxiety /Depression, Functional GI Syndromes,

The Differential Diagnosis.


These patients usually have following features.



Oesophageal conditions and I H D


Only symtoms and signs may never decide diagnosis between these two conditions. It should not be left to clinical judgement. ECG, Endoscopy and ETT should not be withheld. Sometimes delay in diagnosis may prove costly.

In Oesophagitis there is heartburn and dull retrosternal ache, triggered by food, coffee, alcohal, drugs. Relationship to these factors and duration of symptom should be given importance.

In GERD deeply placed burning pain behind the sternum radiating to throat, indicated by the patient with upward movement of the fingers over the chest. Characterisitically it is brought on by bending and by lifting weigth or straining due to increase in intraabdominal pressure. It may occur on lying down for sleep and relieved by sitting up.

Regurgitaition is symptom of Oesophagitis.It may lead to aspiration pneumonia.

Transient dysphagia replaced by persistent dysphagia may suggest of stricture.

GERD is a symptom of hiatus hernia also.

In Oesophageal malignancy

Dysphagia first to solids and then to liquids, progressing persistently in relentless mannaer, combined with weight loss, cough, and hoarse voice should be strongly suggestive.

Dyspepsia when associated with pathology

Keep in mind following conditions.

CA Stomach

Appearance for the first time in middle age of following symptoms must raise the possibility in our minds

Liver & Gall Bladder

Right upper quadrant, pain radiating to right shoulder, nausea and vomiting, fever, jaundice, Murphy’s sign Leukocytosis, disturbed LFTs are the main parameters in this region. But Actually all severe and mild, vague and well defined symptoms in epigastrium must have liver and Gall bladder in the list of D/D.Ultrasound examination is obviously main investigation.

Pancreatitis


Acute Pancreatitis.

Chronic Pancreatitis.


Acid Peptic Disease.


Contributing factors in Etiology.


Pathogenesis.

Clinical features.

The most important points which we, doctors, miss, for unknown reasons even after theoretical knowledge are following.


Asymtomatic patients



Symptomatic Patients.


  1. Disease is characteristically periodic with relapses and remissions. Episodic,”on again, off again”. Initially with long intervals between episodes, often 1-2 years. Episodes lasting only for 1-3 weeks at a time, later on 3-4 weeks. Between episodes patient feels perfectly well.
    If this periodicity is not there, we should have reservations in making the diagnosis of peptic ulcer. This is the single most important message of this Newsletter.

  2. Pain is typically epigastric, gnawing in character.

  3. Hunger Pain in dudenal ulcer.It is usually brought on by hunger, relieved by food.

  4. In Gastric Ulcers eating usally brings on pain.

  5. Night Pain.Again typically pain of DU awakes patient from sleeping at about 2PM.when stomach is empty. Food or antacids relieve it.

  6. Pain Relief. By antacids, food, milk, and by belching or vomiting. More typical of DU.

  7. Other Symptoms Regurgitation, Water brash, heartburn, Anorexia, Anaemia, Nausea/vomiting, Haemetemisis, melena.

  8. In 30 % of patients history is not characteristic. Out of these 30 % large majority is elderly and especially those on NSAIDS.

  9. DU is predominently in males (most of our patients on antipeptic treatment are females) between 20 –50 years of age.

  10. Gastric Ulcers.Tends to be above 40 years of age. Affects both sexes equally. It runs less remittant course as compared to DU.Pain is usually for longer perionds of time. Heart burn and night pain is less common. Anorexia and Nausea/vomiting are more common.

Signs.


  1. Pointing sign, whenever is present is quite significant.

  2. Epigastric tenderness is common but not invariable.

  3. Anaemia may be obvious.

  4. Succession splash in-patients with gatric outlet obstruction may be present.

Investigations.

Management Protocols.


Long term.


Short term.


Two objectives

1 To relieve symptoms

2 To achieve healing of ulcer. Majority of ulcers heals in 4 –6 weeks.


Agents available

1 Antacids

For symptomatic relief

2 H2 receptor antagonists

Inhibit acid & pepsin secretion.

  1. Prostaglandin analogues

Misoprostol

In low doses cytoprotection, in high doses Inhibition of acid secretion and stimulation of mucous and bicarbonate secretion. It should not be prescribed in women of childbearing age (Abortefacient)

4 Proton Pump Inhibitors. These inhibit secretion of acid at parietal cell level.

5 Colloidal Bismuth .

These precipitate in acidic conditions binding with proteins in the ulcer base to form a coat which protects against further acid pepsin digestion. In addition these have strong antimicrobial action against H Pylori.

6 Sucraflate

A natural occuring basic aluminium salt of sucrose octasulphate, which forms an adherent complex with proteins in the ulcer, slough, protecting it from furthers digestion. It is ideal for use in pregnancy

(From Feb 99 Issue)

Helicobacter Pylori

Characteristics.

Another defense (? Probable mechanism of initiation of Ulcer formation)

Is that body’s natural defenses cannot reach the bacterium in the mucus lining of the stomach. The immune system will respond to infection by sending white cells, killer T cells, and other infection fighting agents. However these potential eradicators can not reach the infecting agent because these can not easily get through stomach lining. They do not go away either, though, and the immune response grows and grows. Polymorphs die, and spill their destructive compounds (superoxide radicals) on the


stomach lining cells. Extra nutrients are sent to reinforce the white cells, and the H pylori can feed on this.

Withen a few days gasteritis and perhaps eventually a peptic ulcer results. It may not be H pylori itself which causes ulcer, but inflammation of the stomach lining, i.e, the response to infection is the initiation of the process.

Transmission

It is believed to be transmitted orally. Many researchers think that it is transmitted by means of fecal matter through the ingestion of waste tainted food or water. In addition, it is possible that H.pylori could be transmitted from the stomach to the mouth through gastroesophageal reflux (in which a small amount of stomach’s content is involuntarily forced up the esophagus) or belching, common symtom of gasteritis. The bacterium could be then transmitted through oral contact.

Diagnosis of H.pylori.

It is imperative that prior to testing (except the blood tests)

  1. No antibiotics or pepto Bismol for one month

  2. No Losec for one week

  3. No Pepsid, Zantac, tagamet for 24 hours.should be used.

The Breath Test Fasting for 6 hours is essential. Principle of this test is very simple. Radioactive C (C 14 or C 13,) containing Urea is ingested. Then air breathed out is collected at intervals, and later analysed for the content of C14 or C13.If H pylori are present in the stomach then this urea will be broken down by these and radioactive carbon will be present in expired air, otherwise urea will pass out unbroken.

Blood Tests

Now physicians in their offices are detecting antibodies to H pylori easily even. The only problem is that antibodies remain present even 3 years after infection has been eradicated.

Biopsy

Through endoscopy biopsy can be obtained of gastric mucosa and then a rapid Urease test and microscopy can detect it. It can be cultured for sensitivity tests. Obviously antibiotics and other agents should be withheld for the recommended periods.
