Functional asplenia <strong>in</strong> a patient <strong>with</strong> Rothmann–Makai<br />

syndrome: a pathogenetic relationship?<br />

SIR, A 27-yr-old woman was referred <strong>for</strong> evaluation of mild<br />

anaemia, leucocytosis and thrombocytosis. History revealed a<br />

diagnosis of Rothmann–Makai syndrome (lipogranulomatosis<br />

subcutanea), a rare variant of Weber–Christian disease, at the<br />

age of 13 yr. At that time the patient had presented <strong>with</strong> a m<strong>in</strong>or<br />

fracture of the left ankle, and when the plaster was removed she<br />

was found to have irregular red discoloration on the outer part of<br />

the ankle. This subsequently spread to <strong>in</strong>volve both sh<strong>in</strong>s. A biopsy<br />

specimen was obta<strong>in</strong>ed from one of the erythematous nodules.<br />

In the histopathological sections there was a moderate lymphocytic<br />

<strong>in</strong>filtration <strong>in</strong> the lobules of the panniculus and fibrocytes <strong>in</strong>vad<strong>in</strong>g<br />

the lobules from the fibrous septae. Work-up at that time also<br />

<strong>in</strong>cluded ant<strong>in</strong>uclear antibodies (ANA), rheumatoid factor (RF),<br />

C-reactive prote<strong>in</strong> (CRP), anti-double-stranded DNA, anticardiolip<strong>in</strong>,<br />

anti-Scl-70 and cryoglobul<strong>in</strong>s, which were all negative.<br />

A complete blood count was normal. With these f<strong>in</strong>d<strong>in</strong>gs and<br />

lack of any systemic manifestations, a diagnosis of Rothmann–<br />

Makai syndrome was established. The patient received an 8-month<br />

course of steroids. The erythema resolved and the patient was<br />

left <strong>with</strong> <strong>two</strong> slightly atrophic areas <strong>in</strong> both calves. No relapse has<br />

occurred. History also revealed Hashimoto’s thyroiditis diagnosed<br />

at the age of 14 yr and the onset of alopecia areata at the age<br />

of 20 yr.<br />

The patient has developed progressive <strong>in</strong>crease <strong>in</strong> her leucocyte<br />

count [(8–12) 10 9 /l] <strong>with</strong> a normal distribution and platelet count<br />

[(450–600) 10 9 /l] over the past 8 yr. When seen <strong>in</strong> our cl<strong>in</strong>ic<br />

she was feel<strong>in</strong>g well. Except <strong>for</strong> obesity, the physical exam<strong>in</strong>ation<br />

was unremarkable. Haemoglob<strong>in</strong> was 14 g/dl <strong>with</strong> normal red<br />

cell <strong>in</strong>dices, the platelet count was 668 10 9 /l and the leucocyte<br />

count was 16.2 10 9 /l <strong>with</strong> a normal distribution. A peripheral<br />

blood smear revealed anisopoikilocytosis and numerous<br />

Howell–Jolly bodies, <strong>in</strong>dicat<strong>in</strong>g functional hyposplenism.<br />

Computed tomography revealed a small spleen and no flow signals<br />

could be derived by colour Doppler measurements from the spleen.<br />

Rothmann–Makai syndrome is a rare <strong>for</strong>m of Weber–Christian<br />

disease, usually seen <strong>in</strong> adolescent and middle-aged women [1].<br />

Subcutaneous nodules develop dur<strong>in</strong>g the course of the disease<br />

whereas systemic manifestations are absent. Multiple <strong>pa<strong>in</strong></strong>less<br />

nodules appear throughout the muscle and subcutaneous tissues.<br />

The primary pathological process is lobular panniculitis, which<br />

passes through the same three stages as Weber–Christian disease.<br />

In the first stage, there is acute <strong>in</strong>flammation of the fat lobules <strong>with</strong><br />

fat cell degeneration accompanied by an <strong>in</strong>filtrate of neutrophils,<br />

lymphocytes and macrophages. The second stage is characterized<br />

by many foamy histiocytes, and the <strong>in</strong>filtrate is discretely<br />

localized to the fat lobules. F<strong>in</strong>ally, the foam cells are replaced<br />

by fibroblasts. The first <strong>two</strong> histological stages correspond to<br />

cl<strong>in</strong>ically apparent <strong>in</strong>duration, while <strong>in</strong> the third stage atrophy of<br />

the sk<strong>in</strong> may develop. There are no diagnostic laboratory f<strong>in</strong>d<strong>in</strong>gs.<br />

The diagnosis is based upon cl<strong>in</strong>ical and pathological f<strong>in</strong>d<strong>in</strong>gs.<br />

Corticosteroid treatment does not prevent new lesions or seem to<br />

alter the course of the self-limited disease.<br />

Infiltrative, <strong>in</strong>flammatory or thromboembolic processes <strong>in</strong> the<br />

parenchyma of the spleen can cause a functional loss of the organ.<br />

This phenomenon is called functional asplenia and occurs as a<br />

complication, especially <strong>in</strong> sickle cell disease, lupus erythematosus<br />

(SLE) and after bone marrow transplantation [2–4]. Functional<br />

asplenia has complicated the course of autoimmune diseases other<br />

than SLE, such as candidiasis endocr<strong>in</strong>opathy syndrome and<br />

alopecia areata [5].<br />

This is the first report of functional asplenia occurr<strong>in</strong>g <strong>in</strong><br />

the sett<strong>in</strong>g of Rothmann–Makai syndrome. The aetiology and<br />

pathogenesis of Rothmann–Makai syndrome is still unknown.<br />

Christian–Weber disease often occurs <strong>in</strong> <strong>patients</strong> <strong>with</strong> autoimmune<br />

disorders [6–8], as is the case <strong>with</strong> our patient, re<strong>in</strong><strong>for</strong>c<strong>in</strong>g the view<br />

that Rothmann–Makai syndrome, a variant of Christian–Weber,<br />

may also have an autoimmune basis.<br />

The authors have declared no conflict of <strong>in</strong>terest.<br />

<strong>Infliximab</strong> <strong><strong>in</strong>fusions</strong> <strong>for</strong> <strong>persistent</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong><br />

<strong>in</strong> <strong>two</strong> <strong>patients</strong> <strong>with</strong> Schmorl’s nodes<br />

SIR, Schmorl’s nodes (SNs) are herniations of the nucleus<br />

pulposus (NP) material through the vertebral endplates <strong>in</strong>to the<br />

trabecular bone. SNs are the most common non-<strong>in</strong>tervertebral disc<br />

FIG. 1. Post-contrast T1-weighted image of lumbar sp<strong>in</strong>e <strong>in</strong> the<br />

first patient prior to (A) and 6 months after (B) <strong>in</strong>fliximab<br />

<strong><strong>in</strong>fusions</strong>, show<strong>in</strong>g disappearance of enhancement of Schmorl’s<br />

node and of oedema of adjacent vertebral body marrow.<br />

abnormalities <strong>in</strong> magnetic resonance imag<strong>in</strong>g (MRI) <strong>in</strong> persons<br />

<strong>with</strong>out <strong>back</strong> <strong>pa<strong>in</strong></strong> [1]. However, SNs are seldom symptomatic, and<br />

treatment <strong>with</strong> analgesics, non-steroidal anti-<strong>in</strong>flammatory<br />

drugs (NSAIDs) or corticosteroids usually improves <strong>back</strong> <strong>pa<strong>in</strong></strong>.<br />

In contrast to SNs, herniated <strong>in</strong>tervertebral discs (HIDs) are a<br />

common cause of <strong>back</strong> and radicular <strong>pa<strong>in</strong></strong>. TNF- from the NP<br />

does appear to be pathogenic to nerve roots <strong>in</strong> animal models<br />

of sciatica [2]. Furthermore, TNF- blockade is effective <strong>in</strong><br />

prevent<strong>in</strong>g NP-<strong>in</strong>duced functional and structural nerve root <strong>in</strong>jury<br />

<strong>in</strong> animal models [3]. The efficacy of the TNF- <strong>in</strong>hibitors<br />

<strong>in</strong>fliximab and etanercept <strong>in</strong> leg and <strong>back</strong> <strong>pa<strong>in</strong></strong> has recently been<br />

shown <strong>in</strong> <strong>patients</strong> <strong>with</strong> HID-<strong>in</strong>duced sciatica [4, 5]. These results<br />

of TNF- blockade prompted us to test <strong>in</strong>fliximab <strong><strong>in</strong>fusions</strong><br />

<strong>for</strong> refractory symptoms to conventional conservative treatment <strong>in</strong><br />

<strong>two</strong> <strong>patients</strong> <strong>with</strong> <strong>pa<strong>in</strong></strong>ful SN.<br />

Two women aged 52 and 49 yr <strong>with</strong> SNs received <strong>in</strong>fliximab<br />

because of severe, long-stand<strong>in</strong>g <strong>back</strong> <strong>pa<strong>in</strong></strong> (duration of <strong>pa<strong>in</strong></strong> 24<br />

and 18 months, respectively) <strong>with</strong>out radicular symptoms. There<br />

was a partial response of <strong>pa<strong>in</strong></strong> to treatment <strong>with</strong> NSAIDs and<br />

corticosteroids <strong>in</strong> both <strong>patients</strong>, but severe sp<strong>in</strong>al <strong>pa<strong>in</strong></strong> recurred<br />

after discont<strong>in</strong>uation of the above agents. SNs of the L3 and L5<br />

vertebrae <strong>in</strong> the first patient and of the T12, L1 and L2 vertebrae<br />

<strong>in</strong> the second patient were depicted by MRI. There were MRI<br />

f<strong>in</strong>d<strong>in</strong>gs of active SN (oedema of adjacent bone marrow and<br />

contrast enhancement of SN) <strong>in</strong> the L5 vertebra <strong>for</strong> the first patient<br />

and <strong>in</strong> the L2 vertebra <strong>for</strong> the second patient. After obta<strong>in</strong><strong>in</strong>g<br />

ethics committee approval and written consent from the <strong>patients</strong>,<br />

the <strong>patients</strong> scheduled to receive <strong>in</strong>fliximab <strong><strong>in</strong>fusions</strong> at a dose<br />

of 3 mg/kg at weeks 0, 2, 6 and 14. Response was evaluated<br />

us<strong>in</strong>g a 0–100 mm visual analogue scale (VAS) <strong>for</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong>.<br />

Furthermore, the first patient was evaluated <strong>for</strong> radiological<br />

progression of the lesions by sequential MRI exam<strong>in</strong>ation.<br />

Prior to <strong>in</strong>fliximab treatment, the VAS score <strong>for</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong> <strong>for</strong><br />

the <strong>two</strong> <strong>patients</strong> was 90 and 85, respectively. The first patient<br />

responded promptly to <strong>in</strong>fliximab <strong>with</strong> a decrease <strong>in</strong> VAS <strong>for</strong> <strong>back</strong><br />

<strong>pa<strong>in</strong></strong> to 7, and <strong>back</strong> <strong>pa<strong>in</strong></strong> completely resolved after the second<br />

<strong>in</strong>fusion. Due to a severe allergic reaction just after the second<br />

<strong>in</strong>fusion, she discont<strong>in</strong>ued the <strong>in</strong>fliximab regimen. Six months<br />

later, MRI exam<strong>in</strong>ation revealed disappearance of contrast<br />

enhancement of SN of the L5 vertebra and of bone marrow<br />

oedema (Fig. 1). She has rema<strong>in</strong>ed asymptomatic <strong>for</strong> 30 months.<br />

Letters to the Editor 1589<br />

The second patient completed four <strong>in</strong>fliximab <strong><strong>in</strong>fusions</strong>. She<br />

also responded promptly to treatment. VAS <strong>for</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong> ranged<br />

from 15 to 20 at weeks 2, 6 and 14. She was missed 5 months<br />

after the last <strong>in</strong>fliximab <strong>in</strong>fusion, and had VAS <strong>for</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong> 20<br />

over the follow-up period.<br />

MRI is useful <strong>in</strong> differentiat<strong>in</strong>g between symptomatic and<br />

asymptomatic SNs. In an analysis of MRI f<strong>in</strong>d<strong>in</strong>gs of SNs [6],<br />

the vertebral body marrow surround<strong>in</strong>g the SN was seen as low<br />

signal <strong>in</strong>tensity on T1-weighted images and as high signal <strong>in</strong>tensity<br />

on T2-weighted images <strong>in</strong> all symptomatic cases. These MRI<br />

f<strong>in</strong>d<strong>in</strong>gs were not seen <strong>in</strong> asymptomatic <strong>in</strong>dividuals. Histological<br />

exam<strong>in</strong>ation of <strong>two</strong> symptomatic cases demonstrated bone<br />

marrow oedema and <strong>in</strong>flammatory cell <strong>in</strong>filtration <strong>in</strong> the affected<br />

vertebral body. In a small number of cases of acute SNs [7], there<br />

had been improvement <strong>in</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong> by the time the follow-up<br />

MRI (between 6 weeks and 7 months after the <strong>in</strong>itial MRI)<br />

showed reduction <strong>in</strong> bone marrow oedema. Furthermore, there<br />

was resolution of oedema <strong>with</strong> fatty marrow change <strong>in</strong> <strong>two</strong><br />

cases <strong>with</strong> longer follow-up at MRI (10 and 18 months after<br />

the <strong>in</strong>itial MRI, respectively). In addition to surround<strong>in</strong>g bone<br />

marrow oedema, MRI can reveal vascularized tissue <strong>in</strong> SNs<br />

after the <strong>in</strong>travenous adm<strong>in</strong>istration of contrast material [8].<br />

Contrast-enhanc<strong>in</strong>g SNs are larger and more frequently associated<br />

<strong>with</strong> bone marrow oedema <strong>in</strong> <strong>patients</strong> <strong>with</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong> than <strong>in</strong><br />

asymptomatic <strong>patients</strong>.<br />

Our <strong>patients</strong> had not only severe <strong>back</strong> <strong>pa<strong>in</strong></strong>, which was <strong>in</strong>duced<br />

by active SNs (L5 vertebra <strong>in</strong> the first patient and L2 vertebra <strong>in</strong><br />

the second patient), but also long-stand<strong>in</strong>g symptoms, which<br />

could be expla<strong>in</strong>ed by previous active SNs that were <strong>in</strong> the heal<strong>in</strong>g<br />

stage at the time of MRI exam<strong>in</strong>ation (L3 vertebra <strong>in</strong> the first<br />

patient and T12 and L1 vertebra <strong>in</strong> the second patient). A s<strong>in</strong>gle<br />

<strong>in</strong>fliximab <strong>in</strong>fusion <strong>for</strong> HID-<strong>in</strong>duced sciatica produced not only a<br />

susta<strong>in</strong>ed but also an immediate improvement (<strong>with</strong><strong>in</strong> hours) [4].<br />

The first <strong>in</strong>fliximab <strong>in</strong>fusion led to prompt and significant<br />

improvement <strong>in</strong> <strong>back</strong> <strong>pa<strong>in</strong></strong> <strong>in</strong> our <strong>patients</strong> <strong>with</strong><strong>in</strong> the first 24 h.<br />

There was a complete response to the second <strong>in</strong>fliximab <strong>in</strong>fusion<br />

<strong>in</strong> the first patient, but the second patient did not have a<br />

complete improvement of <strong>back</strong> <strong>pa<strong>in</strong></strong> <strong>with</strong> the four-dose <strong>in</strong>fliximab<br />

regimen. A pilot study is required to validate the results of our <strong>two</strong><br />

case reports.<br />
