NEEDLE BIOPSY OF THE KIDNEY

SiR,-We were delighted with the conservative attitudeof your editorial of Dec. 10. My colleagues and I havedone over 400 renal biopsies in the past few years. No

patient has died as a result of the procedure; the

morbidity has been slight ; and in no patient was surgicalexploration necessary. None the less, we believe that,for the time being at least, the procedure should be donein special centres and only by those who have been trainedin this technique.We were interested in several points raised by you :You state that " several patients have already had as many

as four successive biopsies, giving detailed information of

progressive renal disease which could not have been obtainedby other means. This is not, however, an adequate justifica-tion for a potentially dangerous operation ; and biopsy shouldbe used only when the information it gives will be of directadvantage to the patient, and not merely a rather academicaddition to medical knowledge."

This is a most important statement, for it emphasisesagain that the clinical investigator must be first a

clinician, whose chief consideration is the care of thepatient.2 As we have shown, in selected cases, serial

biopsy of the kidney has provided data which could nothave been obtained in any other way and which was of

great value in the care and management of our patientsand their illnesses. The serially taken biopsies haveincidentally provided new knowledge of the natural

history of diseases which, as John Ryle taught us manyyears ago on the wards of Guy’s Hospital,3 is not " merelya rather academic addition to medical knowledge."

Later you state " that in patients with the nephrotic syn-drome... therapeutic trial [of cortisone or corticotrophin]would give the same information [as renal biopsy] with lessdisturbance to the patient."

Unfortunately this is not true. Without histologicalinformation the response to cortisone or corticotrophinis always unpredictable ; this is hardly surprising if werecognise that " nephrotic syndrome " is but a syndromewith many underlying pathological causes. When thenephrotic patient is first seen the clinician is faced withthe problems of how to treat him, for how long, andwhether to treat a second time. This decision can bemade with far more confidence if the underlying pathologyis known. In our experience, no good has been achievedin patients with severe glomerular lesions who have beentreated with corticotrophin or steroid hormones. Andin some cases at least it is our opinion that their clinicalcondition has deteriorated greatly as a result of treatmentwith these hormones. As far as " disturbance to the

patient " is concerned, our patients who have needed abone-marrow or hepatic biopsy as well as a renal biopsyhave told us they have been least disturbed by the latterprocedure. It has also come as a surprise to us to findthat a number of our female patients were disturbedless by renal biopsy than by catheterisation of theirbladders.

You end by saying : " There are other interesting possi-bilities, but it seems unlikely that renal biopsy will achievethe importance that liver biopsy is now assuming. Many

lives have been saved by liver biopsy in the differentialdiagnosis of prolonged jaundice ; but accurate differentialdiagnosis of renal disease is rarely of such immediate andcrucial importance."We wonder whether this prognostication is based on

personal and comparative experience in the use of needlebiopsy in the care of patients suffering from either hepaticor renal disease.Our experience with hepatic biopsies goes back many

years and is much more extensive than with renal biopsy.To tell the truth, we are embarrassed to admit that wehave saved lives with hepatic biopsies, but even this earlyin the game we will admit having cured some patientswith renal disease as a result of biopsy of the kidney.On the basis of our experience with both types of biopsieswe suspect that biopsy of the kidney will be of greaterpotential value to patients with diseases involving thekidney than hepatic biopsy is to those with jaundiceand other types of hepatic disorder. As a matter offact, we find less use today for hepatic biopsies than wedid a few years ago. This is to be expected because,from hepatic biopsies, we have learned so much of thenatural history of the different diseases which producecirrhosis or result in jaundice that we are now able torecognise them early and clinically.

It is probable that few needle biopsies of the kidneywill be necessary twenty years hence, for by that timeclinical investigators will have sorted out, by renal biopsy,the early and treatable stages of the many diseases whichproduce the end-stage kidney. At present these are

lumped together by physicians under the all-inclusive" chronic glomerulonephritis "-the diagnosis of which isequivalent to a death sentence.

THE FORGOTTEN PATIENT

A. G. DUNCAN.Severalls Hospital,Colchester, Essex.

SiR,-The letter (Dec. 24) from the president andsecretary, Friends of Menston Hospital, states that thefindings of a Daily Express investigation "cannot bedismissed so airily as Dr. Duncan (Nov. 12) would haveus think." I can ignore the rebuke from Mr. Carter andMr. Cripps, but not their inaccuracy. My protest ofNov. 12 neither included nor implied reference to anynewspaper investigation or articles.

CERVICAL VERTIGO

T. J. WILMOT.Tyrone County Hospital,Omagh.

SiR,-I was interested in last week’s article by Dr. Ryanand Dr. Cope.They describe five cases of vertigo associated with

cervical abnormalities and attribute the vertigo in eachcase to interference with the tonic neck reflexes. In

describing each case they state that the aural findingswere negative. What does this mean ? If every eartested was clinically normal and gave normal audio-metric and caloric results, they should state this. If

aticliometry and caloric testing were not done theirobservations on the aetiology of the vertigo are valueless.

Evidence is accumulating rapidly that labyrinthinevertigo is linked closely with the autonomic nerve-

supply to the vessels supplying the inner ear. It would

appear that interference with the cervical sympatheticchain might well have caused the vertigo in all fivecases by causing a temporary alteration in the blood-supply to one or both inner ears.The conception of " cervical vertigo " put forward

by Dr. Ryan and Dr. Cope merely increases the presentconfusion on this subject, and in laying stress on thecervical abnormalities present may tend to preventproper otological investigation of these cases in future.

STREPTOKINASE IN TREATMENT OFINFLAMMATION

SiR,—Professor Dubos, in his account of the Micro-environment of Inflammation, has reviewed a new fieldto which he himself has made many significant contribu-tions.The oedema fluid in inflamed areas contains large

amounts of fibrin. The deposition of fibrin in the tissue-fluids and the formation of thrombi in the arteries,capillaries, veins, and lymphatics help to wall-off thearea of infection by aiding in the formation of a limitingmembrane. This defence curtain has been correctlyregarded as a beneficial structure ; and its preservation,in order to inhibit the spread of infection, has beenconsidered a basic surgical necessity.The advent of streptokinase has produced a change

in thought about the barrier. The chemical nature ofthe limiting membrane might be changed by administra-tion of streptokinase ; for this will indirectly cause lysisof fibrin through activation of plasminogen to plasmin,which is the active lytic agent. Such a change wouldbe beneficial, since the antibacterial drugs, being borneby the blood, cannot pass through the limiting membranefrom without any more than can pathogenic bacteriafrom within. The inefficiency of the antibacterial drugsin the treatment of abscesses, walled-oN cellulitis, andsimilar infections is well recognised.

’ Varidase,’ which contains streptokinase and strepto-dornase, has been used as the source of streptokinase,since a pure preparation of streptokinase has not yetbeen made.2 (The streptodornase content can here bedisregarded.) Varidase was dissolved in physiologicalsaline so that the final concentration of streptokinase was10,000 units per ml. The solution must be stored in a

refrigerator ; and a fresh solution was made daily.5000 units of streptokinase in 0.5 ml. of physiologicalsaline was injected intramuscularly, usually in the glutealarea, twice daily for a total of six doses or more if

necessary. One of the antibacterial drugs must be given,either orally or parenterally, when streptokinase is

injected intramuscularly in the treatment of infection

and/or oedema. A spreading infection may result fromdissolution of the membrane if protection against thecontained bacteria is not provided.In 64 patients with abscess, cellulitis, empyema, epididymitis,

hsemarthrosis, thrombosed haemorrhoids, orchitis secondary tomumps, sinusitis, thrombophlebitis and oedema, 45 excellentand 15 good results were obtained. The 4 poor results werein a patient with paraplegia and extensive decubitus ulcerswhich were resistant to all forms of treatment, in 2 patientswith peripheral arteriosclerotic vascular disease with gangrene,and in a patient with thrombosed haemorrhoids who did notreceive sufficient treatment.

Of patients who were benefited the redness and cedemastarted to decrease in a few after several hours, and in allreceded considerably by the end of two days. In the patientswith granulating wounds, healing was hastened by reductionof the surrounding induration. Delay in healing was notseen in any of the patients. Pain and tenderness at thesite of injection, noted in about 60% of the patients, dis-

appeared about twenty-four to forty-eight hours after theinjections were stopped. The pain and tenderness were

probably due to the streptokinase in varidase, since theywere not encountered in patients given streptodornase alone.A granuloma at the site of injection was not seen in any ofthe patients. A rise in temperature attributable to the

streptokinase was noted in about 10% of the patients.A significant change in the total and differential white-blood-cell counts and in the prothrombin-time was not found;fibrinolysis, determined by the whole-blood technique, wasnot observed ; hsemorrhage, haematomas, and petechiae werenot seen ; and chills, cyanosis, or allergic responses were notnoted. Administration of anti-histamine drugs was not

necessary.
