World Liver Day...ode to the liver

19th April is celebrated every year as the World Liver Day.

The liver is a vital organ of the body and performs more than 500 known vital functions. On this World Liver Day let us pledge to take good care of our good friend the liver

 Pablo Neruda immortalized the importance of the liver in his'Ode to the liver' in Spanish that has been translated in English below

Modest, organized friend, underground worker, let me give you the wing of my song, the thrust of the air, the soaring of my ode: it is born of your invisible machinery, it flies from your tireless confined mill, delicate powerful entrail, ever alive and dark.
While the heart resounds and attracts the music of the mandolin, there, inside, you filter and apportion, you separate and divide, you multiply and lubricate, you raise and gather the threads and the grams of life, the final distillate, the intimate essences.

Submerged viscus, measurer of the blood, you live full of hands and full of eyes, measuring and transferring in your hidden alchemical chamber.
Yellow is the matrix of your red hydraulic flow, diver of the most perilous depths of man, there forever hidden, everlasting in the factory, noiseless.

And every feeling or impulse grew in your machinery, received some drop of your tireless elaboration, to love you added fire or melancholy, let one tiny cell be in error or one fiber be worn in your labor and the pilot flies into the wrong sky, the tenor collapses in a wheeze, the astronomer loses a planet.
Up above, how the bewitching eyes of the rose and the lips of the matinal carnation sparkle! How the maiden in the river laughs!

And down below, the filter and the balance, the delicate chemistry of the liver, the storehouse of the subtle changes: no one sees or celebrates it, but, when it ages or its mortar wastes away, the eyes of the rose are gone, the teeth of the carnation wilted and the maiden silent in the river.
Austere portion or the whole of myself, grandfather of the heart, generator of energy: I sing to you and I fear you as though you were judge meter, implacable indicator, and if I can not surrender myself in shackles to austerity, if the surfeit of delicacies, or the hereditary wine of my country dared to disturb my health or the equilibrium of my poetry, from you, dark monarch, giver of syrups and of poisons, regulator of salts, from you I hope for justice: I love life: Do not betray me! Work on!

Do not arrest my song.

Organ retrieval to get caught in even more red tape
Organ retrieval is possible under current Indian law only from brain dead individuals. The only thing that can cause brain death in a medico legal case is severe head injury. Declaration of brain death unequivocally mandates that the cause of the brain injury must be clear and the circumstances known. All this gobbledygook about poisoning cases being prospective donors is totally irrelevant in the context of brain death. Injuries can be photographed and highly accurate imaging can reveal all that a forensic scientist needs in most cases to establish a cause of death. Injured organs in any case are unsuitable for transplantation and most centres will not be willing to accept donors who have penetrating chest or abdominal trauma. In such circumstances, in the larger interest of judicial process, a forensic team may be asked to be present. This entire process is so devoid of reason and logic that it would be funny if it did not threaten to endanger he lives of hundreds of patients needing life saving transplants. The rates of organ donation in India are already abysmally low and such mindless caveats are the last thing needed.

Donor derived infections in organ transplantation: vigilance is the only answer

http://gu.com/p/3efnm

Recently a kidney transplant recipient in US died of rabies and it has been believed that he may have contracted the infection from the organ he received from a brain dead donor who had encephalitis from unknown cause. This prompted an alarm across five states in the US prompting screening and vaccination of those potentially exposed to the infection.

The demand supply gap of transplantable organs has lead to a clamour for various methods to increase the donor pool. There is an increasing tendency among surgeons to accept organs that in an earlier era would have been considered unsuitable, to benefit the increasing wait list for organs. Although with modern innovations, immunosuppression and surgical techniques, such marginal organs can be transplanted with comparable graft and patient survival, occasionally significant donor related problems can be transmitted to the patient with disastrous consequences.

Deceased donor organ donation inherently is an emergency where the process of brain death declaration, harvesting of organs and the transplant itself has to be done in a short period of time (often few hours). Although all donors are screened for common transmissible infections like HIV, hepatitis B & C, CMV as well as syphilis, there are many infections that could be potentially be in a latent period or in a window period where, there are no clinical manifestations or serological markers to indicate their presence. The results of some tests like fungal, viral or tubercular cultures may only be available after a few days....not in time to make a decision whether organ harvest should be performed or not.

Donor derived infections can be bacterial, fungal or viral. Even cancer cells can be potentially carried from donor to the recipient through the transplanted organ. Infections or tumors (low grade) of the brain that do not spill into the cerebrospinal fluid are often believed to have no risk of transmission and hence not considered a contraindication for organ harvest. Since the immunity of the recipient is suppressed after transplantation to prevent organ rejection, any infections or cancers (suppressed by intact immunity in the organ donor) can escalate leading to rapid clinical manifestation, deterioration and even death of the patient as in the rabies case.

Thankfully donor derived infections are reported in less than 10% organ recipients and in a very small number they can impact graft or patient survival. What is important is to be aware of this problem and screen for problems in the donor as far as possible. If a possible infection is suspected but not confirmed, this information should be passed on to the recipient clearly so that an informed choice regarding the small but present risk of transmission of the infection can be made by the patient and recipient team.

In the rush to accept more and more marginal organs to benefit needy recipients, transplant surgeons should not lose sight of the important doctrine....'first do no harm'.

One hopes that with introduction of rapid microbiological tests like DNA probes and the like, infections will be identifiable within few hours so that such inadvertent mishaps do not accompany what is otherwise an extremely noble exercise.

High Court says NO to donor state NOC

Living donor liver transplant is the only way currently to expand the available donor pool and bridge the ever-expanding gap between need of transplantable organs and availability of organs from deceased donors. The Human organ transplant act of 1994 allows ‘near relatives’ or those who are emotionally related to the recipient to donate their organs out of love and affection. If the donor and the recipient are domiciled in different states, the donor is required to produce a no objection certificate (NOC) from his/her state of domicile that needs to be submitted to the authorization committee of the competent authority under that transplant act in the state where the transplant will be performed.

This certificate does no more than verifies the credentials and particulars of the donor such as donor’s name and address. It does not in anyway confirm or help establish that the donation is out of love and affection and not out of coercion or financial considerations. That is the statutory duty of the authorization committee of the state where the transplant is being performed.

Procurement of this NOC can be an extremely tedious and laborious process requiring multiple trips to the health department officials and district administration. All this imposes a significant cost and is a significantly demotivating factor. Not only that, the time taken can needlessly delay a life saving transplant.

One hopes that this decision by the Bombay High Court (Times of India March 6, 2013) will help clear the decks and avoid this unnecessary hassle that patients and their families are subjected to during their already stressful period.

Early liver transplantation for severe alcoholic hepatitis: cure or lure?

Alcoholic hepatitis is a clinical syndrome characterised by jaundice and liver failure following decades of significantly heavy alcohol consumption ( >100g daily).

Not uncommonly it results following abstinence periods of weeks to few months or following intermittent binge drinking interspersed by short periods of abstinence.

Although the diagnosis of alcoholic hepatitis is mainly clinical ( enlarged tender liver,  fever, ascites, jaundice, muscle wasting accompanied by renal failure and encephalopathy in more severe cases), the following laboratory criteria suggest its presence in absence of other causes

1. Serum bilirubin >5mg/dL
2. AST (SGOT) > 300
3. AST/ALT (SGOT/SGPT) >2
4. INR >1.5
5. White cell count >10000 cmm

Assessment of severity of alcoholic hepatitis is traditionally done using the Maddrey discriminant function ( 4.6* (PT-PTcontrol) + Serum bilirubin). It is believed that patients with a Maddrey Discriminant Function >32 may benefit from steroids and have poor prognosis.

The Lille model uses age, bilirubin (day 0,7) creatinine (day0), Prothrombin time (day 0) and albumin (day 0) to evaluate prognosis in SAH. A score > 0.45 predicted poor survival ( 30%) at 6 months very reliably.

The MELD score has also been found to be useful in patients with SAH where a score >21 significantly predicts high mortality at 90 days (<20 p="">
The Glasgow score for alcoholic hepatitis takes into account age, wbc count, urea, INR and bilirubin. A Glasgow score of >8 n day 1 or day7 of admission predicts poor prognosis.

Treatment for severe alcoholic hepatitis has evolved over the decades but is largely supportive.

Broadly the measures include

1. Alcohol abstinence & Psychotherapy
2. Corticosteroids ( controversial as results are equivocal, improves early survival if DF >32)
3. Pentoxyfylline  ( reduces renal dysfunction)
4. Silymarine (no evidence of benefit)
5. Infliximab /Etanercept (no benefit, may increase infection)
6. Vitamin E/ Parenteral nutrition / Oxandrolone (no survival benefit)

Traditionally severe alcoholic hepatitis (SAH) has been considered a contraindication for liver transplantation
for the following reasons

1. Since patients have been drinking until recently, a period of abstinence will improve their condition
2. Patients with SAH often have infection or liver failure and poor nutritional status and therefore are poor candidates for major surgery.
3. There is a significant chance that these patient not having had enough time to receive psychological assessment and counselling, have a significant chance of returning to alcohol

Most systems therefore have insisted on a six month period of abstinence before being listed for liver transplantation. Studies however have demonstrated that patients of SAH who do not improve significantly within three months of abstinence have reduced survival prompting a rethink of the six month rule.

Transplant physicians involved in the care of patients of SAH who continue to deteriorate despite abstinence and best supportive care, are often faced with an unenviable dilemma whether to transplant early or choose masterly inactivity till the patient has been abstinent for the period of at least three months. Since a deceased donor organ is a gift to society, waiting is probably just because early transplant diverts the scarce resource to a high risk patient who may waste the gift by early return to alcohol. Living donor organ however is a private gift and therefore using a living donor organ for early transplant conceptually does not deprive another potential recipient and is hence socially justifiable. The ethical foundation of living donor transplant is double equipoise ie the risk (however small) to the donor is justified only if the benefit to recipient is great. In this context recipient benefit cannot be equated to early survival alone but should also encompass recidivism and later issues. Despite this pleas and emotional pressures from a family of a deteriorating patient to perform an early living donor transplant can be unnerving.

Until recently a volume of scientific literature attested to the fact that early liver transplant in severe alcholic hepatitis was associated with either poorer early survival ( mean 55% vs 75% without SAH) or higher rates of recidivism (>33% vs 20%). Recent improvements in post-transplant management and critical care have led to improvement in survival of survival of critically ill transplant candidates including those with SAH and pre-transplant abstinence has been found not to be an unequivocal predictor of recidivism rates after transplant. Both these developments have prompted a re-evaluation of policies regarding liver transplant for SAH.

A recent multi-centre study from Europe (New England Journal of Medicine) suggested that early (deceased donor) liver transplantation performed for  patients with first episode of SAH and who were steroid non-responders was associated with good survival (77% at 6 months) as compared to 23% in controls without liver transplant. The recidivism rate was 11% and no recidivism was seen in first 6 months. There was no significant diversion of organs to these cases as strict criteria and multidisciplinary consensus was mandatory for performing transplant.

Some centres in India have been conveniently using this study to justify early liver transplant in patients with SAH. Even the success of early living donor transplant for acute liver failure has been used to justify early living donor transplant in this totally uncomparable situation. The authors of the European study themselves have clarified that living donor transplant for the same situation is not justifiable and deceased donor transplant is justifiable only if deceased donor organs are not scarce. In India where deceased donation is rare, it is tempting (economically) to perform early transplant using a living donor since it does not deprive society of an organ and the distressed family often sees it as the only light at the end of the tunnel. Early transplant is even used as a lure to transfer such desperate patients from other centres that do not subscribe to this ethos.

Unfortunately the results of this exercise have been poor with unflattering survival and significantly higher recidivism among survivors, yet it continues to be offered as a last hope in an otherwise deteriorating situation either capitulating to pressure of family of for less honourable economic reasons.

This is one desperate situation that should not be dealt with by desperate measures.

Liver Transplant Surgery: if you choose to travel the distance there is a price to pay

Liver transplantation is a complex procedure and the transplant operation is just one event in the journey that a patient and his caregivers have to embark on. In any long process, well begun is half done and therefore this event ie the operation, if performed and tolerated well, increases the chances of patient survival and eventual well-being. However it must be remembered that this in itself does not ensure a smooth course.

Nearly 10-20% liver transplant patients will need to have an intervention ( either radiological, endoscopic or surgical) during the same admission as their transplant procedure. Often these interventions if not performed emergently and by experienced personnel, can lead to loss of graft and indeed loss of life. It therefore follows that the transplant team should be available round the clock to anticipate, detect early and intervene in time to salvage the graft and the life of the patient.

In the first three months following discharge, at least 10% transplant recipients may need hospital admission under the care of the transplant team for problems related to infection, rejection or surgical complications. If these are not managed well, they can lead to graft as well as patient loss.

There is a tendency among Indian patients to jump on the bandwagon and travel great distances to few transplant centers for their surgery (often at an exploitatively elevated cost) or have transplants performed by commercially-motivated visiting teams attracted by real or exaggerated claims of success, aggressive marketing or through inducement of their referring physicians. While there is no doubt that the right to choose lies with the patient, there is often no consideration given to the availability of continuous surveillance once the patient returns to his community. Patients are lulled into a (false) sense of complacency by the promise of periodic visits by members of the transplant team or placement of inadequately trained minions in the community to look after them for which a 'follow up fee' is charged upfront.

I have recently come across several cases of these 'transplant orphans' who having undergone 'successful' surgery at centers far away from their communities, have suffered due to the lack of direct surveillance and landed up in graft damage or even graft loss. Travelling the distance for managing the complication, imposes an even greater financial burden and moreover patient status may not even allow safe travel in time even if one were to disregard the economics. These patients are frustrated and left to fend for themselves or cared inadequately by inexperienced personnel through telephonic or email directions from the transplant centre. They then have no alternative to running from pillar to post to get proper care from nearby transplant physicians who may not necessarily be willing to takeover the case.

I think anybody traveling to a distant center for a complex procedure like liver transplantation should really consider the availability of longterm experienced followup in his community and ensure that adequate provisions are made for this before the surgery (whenever possible).

There is often a price to pay for going the distance and sometimes the price can be just too high!
