Are patients with G6PD Deficiency to avoid eating prawns that have been farmed?
In his very informative editorial (March 4) Geoff Scott says “Chloramphenicol is also used in certain practices in agriculture, such as the farming of prawns” [Reference 1]. Should I, therefore, mention to my Ghanaian patients one in five males (hemizygotes) of whom were born with G6PD Deficiency [References 2-4] that eating prawns that have been farmed could lead to what Geoff Scott calls “dangers of unwanted effects” [Reference 1]?
That would increase my list [See Reference 5] from 20 to 21 of how to recognize effects of Glucose-6 Phosphate Dehydrogenase deficiency in Ghanaian hemizygotes, female heterozygotes, and the homozygotes that constitute 1 in 16 of all females at home in Ghana and in the diaspora [2].

Sickle Cell Disease Patients dying from Opiates: Why no co-operation among doctors?
I am very concerned at what appears to be inadequate cooperation among medical practitioners who I had always assumed worked in harmony to improve the quality of patients' lives and save lives that can be saved.
If I have understood correctly, in the first few years of training, medical practitioners learn that opiates, notably morphine and heroin (Diamorphine) have an effect on the cerebellum and deprive the system of oxygen. It is therefore advised that as there are numerous alternatives available, they should absolutely not be used as a pain killer unless a patient is terminally ill, very near to death and in excruciating pain which no other pain killer can relieve.
Do I understood that those physicians who continue to prescribe these drugs have forgotten what they have been taught or choose to ignore the fact even when reminded? What is happening to the life-saving dictum of the profession where some doctors are concerned?
In November 2008, I went to an emergency room at a clinic in Geneva , Switzerland where I live, with a blasting chest pain. My condition was soon further complicated by excruciating pain in my left hip.
My new lease on life is because medical practitioners did not contest my refusal of a morphine injection to relieve excruciating pain in my chest and hip. The physicians attending to me would have loved to relieve me of the pain with morphine but respected the knowledge, however little, and understanding I had of the way in which opiates affect the brain and therefore the entire system. They deprive the system of oxygen which is desperately vital in my condition, Sickle Cell Disease.
I had double pneumonia and pleurisy. The infection had provoked a sickle cell crisis. Before they had realised the extent of my illness, the fact that I was a sickle cell disease (SC) patient was enough for the physicians attending me NOT to insist on administering morphine. One of them said that my pain had reached the maximum the human body could endure.
Unfortunately, some physicians force patients to have morphine. Whether one is a sickle cell patient or not, opiates in my opinion, are not to be recommended.
I am allergic to aspirin and therefore must avoid no fewer than 34 prescription and over-the-counter medications, including Ketorolac (Toradol) which is very effective in relieving excruciating pain.
There are so many misconceptions about sickle cell disease that I took the book “The Sickle Cell Disease Patient” by F I D Konotey-Ahulu to the clinic and my daughter handed it to the physician attending to me. My three adult children are well informed about my health issues and therefore telephoned Professor Felix Konotey-Ahulu abroad for guidance. My physicians were very happy to consult with him by telephone. He confirmed that I was right to refuse the administration of morphine and together they co-operated in making me comfortable and well again.
I was fortunate enough not to need a blood transfusion (neither total nor partial).
It may help medical practitioners to know that over the 12-days that I was in the clinic in Geneva, medication I was given was Dafalgan, Valium, Tramal, Perfalgan, Rocephine, Klacid, Franxiperine, Nexium and Tavanic and Motilium lingual. I also had Oxygen, NaCl and Glucose. No Morphine or Diamorphine!
On leaving the clinic in Geneva , I went to a convalescence clinic. A physician at the convalescence clinic asked why I had refused morphine. When I explained why, a colleague of his pointed to the back of his head, reminding him of the effect opiates have on the brain.
I am privileged to interact with physicians for whom I have the highest respect, one reason being because they take due consideration of what I, their patient, say and they listen to my children as well. The physicians are humble enough to take hold of a receiver and cooperate with another physician abroad in saving a life. They admit to me that they have been very happy to deepen their knowledge and would be pleased to learn more.
Had I been given the morphine or any other opiate, because of my double pneumonia with sickle cell disease, I would not be writing today, pleading with physicians to have compassion on patients who sometimes suffer very uncomfortable psychological problems (however temporary) as a result of having been given opiates and those who die as a result of having been given opiates.
The physicians who seem not to understand should try putting themselves in the position of families plunged into unbearable grief because of carelessness – a loved one was given opiates unnecessarily.
In spite of myself I begin to wonder whether Professor Felix Konotey- Ahulu's very practical and uncomplicated life-saving advice is being ignored by some medical practitioners because of his African origins. I believe his advice is based on what every medical practitioner learns at medical school.

UK drug related deaths are still rising: So where is NICE?
http://www.bmj.com/cgi/eletters/339/sep01_1/b3536#219836
Susan Mayor, 5 September, has done well to draw attention to 2 reports that reveal “the numbers of people dying because of poisoning from legal and illegal drugs are still increasing” [1] The first report said “Almost a third of the deaths where specific drugs were mentioned on the death certificate were related to heroin or morphine” [1, 2] The second report from St George’s University of London showed a 2.7% rise in the number of drug related deaths confirmed by inquest. Here too “Heroin and morphine accounted for most of these deaths” [3]. And these were the very drugs that the NCEPOD Report [4] found had produced deaths in sickle cell disease patients from overdose, and about which I continued to protest [5- 8].
HOW LONG WILL THIS CONTINUE FOR?
How long this situation is destined to continue is not clear. Writing to the Prime Minister and Health Ministers as I did, produced a response from

In the light of the above I make no apologies to take it upon myself to advise NICE to stop standing on the sidelines, and add to their many pronouncements one that forbids the “legal” use of Heroin (Diamorphine) for sickle cell disease patients. This, at least, was one thing NICE could learn from the

The real answer for now, and the future, as I have been saying for decades is Genetic Counselling and Family Planning [18, 19] warning my fellow Africans that if they did not check themselves for a beta-globin gene variant (an ACHE gene) they might suddenly find themselves with a child born with an ACHEACHE phenotype (ACHE from father and ACHE from mother), like Sickle Cell Disease, and “the genetic burden on the National Health Service will go up and up” [20].

Publications and CV Updated
I have recently updated my list of publications on the website. You can view this on the links below
http://www.konotey-ahulu.com/publications_annual.htm
I have also updated my CV which can be seen here
WARNINGS FROM A QUARTER OF A CENTURY AGO
British Medical Journal 20 April 1985 Volume 290, page 1214
First, presentation. Epistaxis, priapism, enuresis, numbness of the lower lip, sudden aphasia, hemiplegia, blood in the urine, deep jaundice, large tummy, nails white as a sheet, loud precordial murmurs, bruit de diable at the root of the neck, unexplained fever, cough with tachypnoea, fatigability, swollen hands may each and severally be the first indication that the child has sickle cell disease.' Alternatively, a child's condition may have nothing to do with sickle cell disease but may later be worsened by it-for example, within seven days lobar pneumonia can become pneumonia plus infarction plus pulmonary abscess.' Presentations may also differ from those described in the textbooks. (1) Teenagers of 12, 13, 14, or 15 years with SS disease may have spleens which, far from vanishing, are enlarged. (2) The child with genuine SS disease (parents AS, AS) with haemoglobin of 12-3 g/dl should not be treated as having sickle cell trait, because the potential for devastating in vivo sickling is there. (3) Extreme fatigability with “nails as white as a sheet” during an attack of measles indicates an aplastic crisis from the measles virus. Haemoglobin drops to 2-5 g/dl within 48 hours. As little as 100-150 ml of packed cells for a 5 year old child and not more than one unit for a 15 year old given over eight hours is lifesaving, even when the haemoglobin was less than 3 g/dl to start with.
Secondly, clinicians should anticipate disasters in patients with sickle cell disease. For example, if perioperative fluid therapy is not planned for a child about to undergo surgery the child will end up with a stroke. Anaesthetists are now more careful than ever so their success is virtually 100″,,, but fluid management before, during, and after operation often leaves a lot to be desired. The clinician should also be aware that the patient who has been admitted and discharged twice within the past week has come in again to die unless the whole management is overhauled.
Thirdly, there are many dangerous combinations of circumstances that may lead to disaster for the unwary. (1) Personnel: the houseman or GP is away for the weekend; the locum has little clue about what is happening and goes by the packed cell volume or haemoglobin concentration rather than the patient's condition; the casualty department may refuse to admit the patient, quibbling over whether the patient should go under a physician or a haematologist. (2) Clinical: abdominal pain might be due to sickle cell crisis,2 3 or the crisis could also have been precipitated by acute appendicitis.' (3) Genetic: hardly any west African with sickle cell anaemia is without one or more of the other hereditary erythrocytopathies: 86'U/ have concomitant lac or 2ac thalassaemia, and, although this is supposed to ameliorate the SS phenotype, 2OO, of the men and 16″(, of the women also have glucose-6- phosphate dehydrogenase (G6PD) deficiency.4 Contrary to what is claimed from the USA, G6PD deficiency on top of sickle cell disease is an added liability4 (Luzzato L, paper at International Symposium on Sickle Cell Anaemia, Abidjan, Ivory Coast, 1975). Workers in the UK should always identify which of their patients have G6PD deficiency, because several antimicrobial agents and analgesics which are given to help may in fact harm the patient.

Current “hit and miss” care provision for sickle cell disease patients in the UK
Current “hit and miss” care provision for sickle cell disease patients in the UK
Following her article [1] on NCEPOD [2] Susan Mayor has, again, produced a succinct summary [3] of the recent publication of ‘Standards’ on the care of patients with sickle cell disease (scd) in the UK [4], written by a multidisciplinary working group chaired by Consultant Haematologist Dr Ade Olujohungbe. The public launch of the publication was on 9 July in the House of Commons where the Archbishop of York, Dr John Sentamu, said: “These Standards are another step in providing consistent care” [3].
HIT AND MISS CARE PROVISION
Hitherto, consistent care has not been UK’s strong point. The description by the ‘Standards’ Group’s chairman, Dr Olujohungbe who, in my opinion, has proved to be the most experienced Clinical Haematologist in the UK on the scd patient since Hammersmith Hospital’s Professor Lucio Luzzatto with whom Olujohungbe was closely associated, underlines what Graham Serjeant [5] and I have bemoaned for years. Olujohungbe said “The care provision for sickle cell disease is currently hit and miss, depending on the attitudes and experience of health professionals” [3]. This sad diagnosis by the leading UK haematologist on the scd patient was precisely why “NCEPOD found that many patients died of complications caused by excessive doses of opiods” [1, 2].
RESPONSE OF TEN DOWNING STREET
During the week when UK media (radio, television, & newspapers) were full of news that the Prime Minister was inviting personal phone calls and contacts on people’s concerns I took the opportunity to write to The Right Honorable Mr. Gordon Brown drawing his attention not only to the publication of the NCEPOD Report [2], but also to the international responses that were beginning to pour in [6]. The reply I got, dated 25 June 2008, from Ten Downing Street was encouraging: “Dear Dr Konotey-Ahulu – The Prime Minister has asked me to thank you for your recent letter and enclosures. Mr. Brown has asked that your letter be forwarded to the Department of Health so that they may reply to you on his behalf. (Signed) MR R SMITH”.
RESPONSE OF THE DEPARTMENT OF HEALTH
I looked forward eagerly to answers to the 3 questions I posed in my correspondence, namely (i) With respect to scd patients dying with overdose of opiods (heroin & morphine) in their blood “What kind of supervision led to this?” [6a] (ii) Why should West Indians and West Africans who did without morphine in their countries be put on morphine pumps when they were admitted to UK hospitals? [6a] (iii) To those UK haematologists who say “unbearable pain is unbearable pain, which must be treated with the most potent analgesic drugs known” I posed this third question, how many of them would prescribe diamorphine (heroin) monthly for their teenage daughters whose dysmenorrhoea was simply unbearable? [6a]. The Department of Health wrote back to me Ref; TO00000325139 dated 16 July 2008. Signed by “Shelley Wilson, Customer Service Centre”. All the questions were totally ignored. Would the National Institute of Clinical Excellence (NICE) now provide specific answers to these my 3 questions?
OUR GENETIC FUTURE
Africans, African-Caribbeans, and African Americans must wake up and realize that their genetic future depends on themselves, and not on any Department of Health. We must reduce the genetic disease burden, starting now, otherwise their children will continue to be subjected to “hit and miss” health care provision, ending up on heroin and morphine pumps. “Unless we Africans are involved in genetic counseling” and voluntary family size limitation (GCVFSL), I said not long ago “the genetic burden on the National Health Service will go up and up” [7]. What is more to the point, unless we take this very seriously our children and grand children will suffer greatly from scd [ACHEACHE syndrome], for “one in three West Africans in the UK has a beta-globin variant gene (ie NORMACHE) whose unsuspecting owner needs to be identified and helped with genetic counseling and family size limitation” [7]. Those who do not quite believe the enormity of the NCEPOD Report [2] should, please, start by taking a good look at how the rest of the world regards the “hit and miss” approach to the present care of sickle cell disease patients in the United Kingdom [6a-6j].

NCEPOD REPORT Reveals Sickle Cell Disease Patients in UK Hospitals Dying from Overdose of Morphine and Heroin (Diamorphine)
Sickle: A Sickle Crisis? (2008) info@ncepod.org
The National Confidential Enquiry into Patient Outcome and Death (NCEPOD)
published a report in May 2008 which showed that within the 2 years January
1 2005 to December 31 2006 “Nine out of the 19 patients with sickle cell
disease who had pain on admission and who then died had been given
excessiove doses of opiods”.
The International response to this revelation was huge – see
http://www.bmj.com/cgi/eletters/336/7654/1152-a#196224 and the subsequent 9
other comments.
Later, on 9 July 2008 in the House of Commons, another report was published
called “The Standards for The Clinical Care of Adults with Sickle Cell
Disease in the UK”. The Chairman of the Group that produced the report
described the present care of patients in the UK as a “hit and miss affair
depending on the attitudes and experience of health professionals”. Dr
Konotey-Ahulu's reaction to this in the British Medical Journal on line is

G6PD Deficiency in Ghanaians: How to recognise it
G6PD Deficiency in Ghanaians: How to recognise it
In their instructive seminar Professors Capellini and Fiorelli put Africa first in the list of areas with the “highest frequencies of G6PD deficiency” (Jan 5, p 64) [1], so what are the Ghanaian associations?
(i) “Dorkita, I’m passing coca cola urine”. Mist alba, septrin, fansidar, chloramphenicol, APC, are the greatest offenders [2].
(ii) Typhoid disease [3 4]
(iii) lobar pneumonia with jaundice [2 4]
(iv) Renal failure [5](v) No enzyme-at-all in 5% G-6-P-D deficient males [6]
(vi) Greater delay in recovery from coma [7]
(vii) Greater representation in Cirrhosis of the liver [7]
(viii) Greater proportion of diabetics [7]
(ix) Sickle cell disease patients fare worse [8 9 10]
(x) Female homozygotes (X-X-) have more severe disease than hemizygotes (X-Y), making me wonder “how that can be reconciled with the Lyon hypothesis of inactivation of one X chromosome” [10, page 105]
(xi) Periodic intravascular haemolysis from interaction between “alpha thalassaemia type 1 equivalent to African homozygous alpha thalassaemia type 2, with G-6PD Total deficiency” [11]. Exercise acts as a trigger. The combination per se does not appear to account for the hyperbilirubinaemia in babies [All cases of ‘march haemoglobinuria’ must be screened for both alpha thalassaemia and G-6PD deficiency].
(xii) The enzyme is found in liver, brain, kidney, adrenals, skin, pancreas, nerve and muscle, hence the extra-erythrocytic manifestations of G6PD deficiency. Bedu-Addo’s description of chloroquine induced bilateral ptosis [12] could have been in one with no enzyme.
(xiii) Hepatomegaly with quick progression to cirrhosis [7]. (xiv) Viral Hepatitis is commoner in G6PD deficient patients, and characterised by intrahepatic cholestasis [13]. (xv) Terminology of A-minus (attributed to Africans) and B-minus (Mediterranean)is meaningless, as in A-minus Ghanaians “absence of enzyme in new red cells” produces cases “similar to the Mediterranean type of total deficiency” [6]
(xvi) There is an inexplicable north-south divide of incidence: 11% of males are deficient in the north [14] while 23% have G6PD deficiency in the south [15].
(xvii) Protection against malaria has not been proved in Ghana for hemizygotes and female homozygotes [7]. Indeed, blackwater fever is often related to G6PDdeficiency
(xviii) “Sabolaa kε Emanbii yi” is a truism in my Krobo tribe: “Onions and M&B disagree” [16]. In the Colonial days some who took sulphonamides (‘M&B’) for infections fell gravely ill on eating onions. Dipropyl disulphide in onions “alters G6PD in the metabolic chain within the erythrocytes, which causes denaturing and precipitation of haemoglobin” [17].
(xix) Genetic Counselling goes beyond haemoglobinopathy to erythrocytopathy. A G6PD deficient sickle cell trait mother (AS) has two healthy daughters with her sickle cell trait (AS) husband, and they seek advice for a third pregnancy hoping to get a boy. She is told that although neither daughter has inherited her deficiency, and both avoided sickle cell anaemia (SS), her next child could be SS with G6PD deficiency (severe if a boy) [18]
(xx) Voluntary family size limitation (VFSL) [19] is the advice I give hemizygotes who (in Africa) have a high male procreative superiority index (MPSI) [20] in that males have more children than females, with consequent greater donation of abnormal genes to the next generation.
