[Systemic sclerosis and pregnancy].

PURPOSE: Pregnancy in a patient with systemic sclerosis (SSc) may pose a double problem to the medical team: influence of SSc on pregnancy and consequences of pregnancy to SSc manifestations. CURRENT KNOWLEDGE AND KEY POINTS: Concepts have evolved. SSc was considered for a long time not only as not very propitious for pregnancy but also as a strict contraindication for procreation because risks for the mother and the baby were thought to be major. Currently, fertility is thought to be normal. Miscarriages and small-for-gestation age infants rate do not seem to be higher in SSc. Maternal and perinatal mortality is also not higher in SSc without severe visceral manifestations, i.e. without either pulmonary hypertension, or cardiac or respiratory insufficiency. Conversely, there is a significantly higher frequency of premature infants in SSc. As regards influence of pregnancy on SSc, the greatest fear is the occurrence of renal crisis, which may be life threatening for both mother and child. Each elevation of blood pressure, even if this increase is mild, should be considered as potentially very serious. However, pregnancy itself does not seem to increase the risk of renal crisis. Consequences of pregnancy to SSc manifestations are various but usually mild. FUTURE PROSPECTS AND PROJECTS: SSc is not a strict contraindication for pregnancy only if severe organ involvement, diffuse subset of SSc or recent onset of the disease has been ruled out. Physicians should be aware of specific problems, which SSc is possibly posing during pregnancy. Finally, it has been recently suggested that pregnancies could be involved in the pathogenesis of SSc through persisting microchimerism of fetal origin.

[Cogan syndrome or sarcoidosis?].

INTRODUCTION: The Cogan's syndrome is characterized by the association of vestibulo-auditory dysfunction, non syphilitic interstitial keratitis or another significant inflammatory eye lesion. Some authors consider this disease as a vasculitis, because it is frequently associated with systemic manifestations. Based on Cogan's diagnostic criteria, Cogan's syndrome may be part of other systemic diseases, as polyarteritis nodosa or Wegener's granulomatosis. EXEGESIS: We report the case of a patient who presented with a Cogan's syndrome and developed further sarcoidosis. CONCLUSION: If Cogan's syndrome is characterized as systemic disease because of its association with aortitis or other vasculitis, on the other hand, clinical presentation may be part of many other systemic diseases.

[Psychiatric complications of corticoid therapy in the elderly over 65 years of age treated for Horton disease].

OBJECTIVES: To analyse steroid psychiatric related complications in aged (> 65 years old) with temporal arteritis (TA). METHODS: Retrospective cohort study. PATIENTS: In a cohort of 126 elderly patients with a diagnosis of TA and followed with a mean period of 64 months, clinical and biological presentations, outcome and corticoid adverse effects were recorded throughout the follow-up period. RESULTS: Twenty patients (16%), (mean age: 73 +/- 7.9 years, male n = 6) exhibited corticosteroid related psychiatric complications. Symptoms appear to be dose dependent and generally begin during the first month of treatment. Psychiatric disorders were as follow: mood disturbances (n = 8), depression (n = 6), mania (n = 3), anxiety neurosis (n = 2) and dementia (n = 1). Three patients were hospitalized in psychiatric units and 2 in nursing home. Psychiatric adverse affects appears to be more frequent with prednisone than prednisolone (P < 0.05).

[Wegener's granulomatosis in the elderly patient].

PURPOSE: To determine aged-related variations in clinical and biological presentation and outcome in Wegener's granulomatosis. METHODS: In a retrospective cohort study of 35 patients with a diagnosis of Wegener's granulomatosis, 24 patients (69%) younger than 60 years of age and 11 (31%) aged 60 years or older were compared for clinical and biological characteristics. RESULTS: Clinical presentation was the same in the two groups; lymphopenia was more common in the elderly group (P > 0.05). Despite a similar treatment regime, outcome was significantly worse for the elderly group (> or = 60 years), with a mortality rate of 36% versus 8% in the control group. Mortality was essentially due to delayed infectious complications, raising the problem of a less intensive immunosuppressive treatment after remission.

[DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) syndrome after sulfasalazine and carmazepine: report of two cases].

INTRODUCTION: To better individualize drug hypersensitivity reaction, Bocquet et al. have recently called this adverse drug reaction DRESS (Drug Rash with Eosinophilia and Systemic Symptoms). EXEGESIS: We report two cases of DRESS and highlight the main characteristics of this syndrome. Two patients presented severe febrile skin eruption following drug intake (carbamazepine or sulfazalazine), with hypereosinophilia and hepatitis. All symptoms resolved after drug withdrawal and corticosteroid therapy. DRESS syndrome is an idiosyncratic reaction characterised by febrile eruption, occurring 2 to 6 weeks after the beginning of the treatment, accompanied by systemic symptoms and biological abnormalities (hypereosinophilia, hepatitis). Some complications can occur. This syndrome can be fatal. Numerous drugs can be responsible for this reaction to medication. The physiopathology has not yet been elucidated, and the treatment is not codified, but the triggering agent must immediately be stopped. Corticotherapy is sometimes used. CONCLUSION: It is important to recognize this entity recently named DRESS syndrome because it can mimic other pathologies, is potentially serious, and because withdrawal of the incriminating drug is imperative.

[Pulmonary hypertension screening in systemic scleroderma: a cohort study of 67 patients].

PURPOSE: Pulmonary hypertension is a severe complication of systemic sclerosis and has emerged as a major cause of morbidity and mortality in this condition. Treatment is all the more efficient as pulmonary hypertension is early diagnosed. A good knowledge of the clinical, biological and functional features of pulmonary hypertension in systemic sclerosis is therefore necessary to suspect and to diagnose pulmonary hypertension as early as possible. METHODS: Sixty seven patients with systemic sclerosis were retrospectively studied. We compared clinical, immunological, functional (spirometry) and morphological (pulmonary fibrosis) features according to the presence (n = 25) and the characteristic of pulmonary hypertension (isolated or secondary) or the absence (n = 42) of pulmonary hypertension, assessed by Doppler echocardiography. RESULTS: CREST syndrome (calcinosis, Raynaud's phenomenon, oesophageal involvement, sclerodactyly and telangiectasia) was more frequent in patients with isolated pulmonary hypertension than in patients without PH (72.7% vs 28.5%, P < 0.05; odds-ratio [OR] = 6.6) and dyspnea was more severe (P < 0.001; OR = 11.4). The age at time of pulmonary hypertension diagnosis was higher in patients with secondary pulmonary hypertension than in patients with isolated from (median: 62.5 years (range: 32-35) vs 53 years (range: 37-85), P < 0.05). Patients with isolated pulmonary hypertension had anticardiolipin antibodies more frequently than patients without pulmonary hypertension (72.7% vs 35.7%, P < 0.05). Isolated reduction of diffusing capacity was preferentially observed among patients with isolated pulmonary hypertension than among those without pulmonary hypertension. A linear relation between systolic pulmonary artery pressure values and diffusing capacity values (r = 0.72, P < 0.01) was found. Isolated reduction of diffusing capacity was more frequent in patients with isolated pulmonary hypertension than in patients without pulmonary hypertension (63.6% vs 14.3%, P < 0.001; OR = 10.5). CONCLUSION: The severity of pulmonary hypertension in systemic sclerosis justifies a systematic screening by Doppler echocardiography and diffusing capacity measurement. Our results allow us to better define the characteristics of sclerodermic patients with isolated or secondary pulmonary hypertension. The search for pulmonary hypertension should be repeated with time and clinicians should be particularly vigilant in the case of a patient presenting these characteristics.

Scleromyxedema (lichen myxedematosus) associated with dermatomyositis.

A 41-year-old white man is described with papules of the lower and upper back, the neck and the upper chest, a marked deposition of mucin in the upper reticular dermis, and an IgG lambda monoclonal gammopathy strongly evocative of scleromyxedema (lichen myxedematosus). Additionally, he developed intense myalgia, muscle weakness and rhabdomyolysis, which were associated with heliotrope erythema, photosensitivity and an erythematous rash of the dorsum of the hands with Gottron's papules. Muscle biopsy revealed an inflammatory myositis, and dermatomyositis was diagnosed. The association of dermatomyositis and secondary mucinosis, or muscle involvement in primary papular mucinosis are not rare. However, the association between scleromyxedema and dermatomyositis has only exceptionally been reported.

Cannabis arteritis revisited--ten new case reports.

The purpose of this paper was to revisit the old concept of cannabis arteritis first described in the 1960s and report 10 new cases. Ten male patients, with a median age of 23.7 years developed subacute distal ischemia of lower or upper limbs, leading to necrosis in the toes and/or fingers and sometimes to distal limb gangrene. Two of the patients also presented with venous thrombosis and three patients were suffering from a recent Raynaud's phenomenon. Biological test results did not show evidence of the classical vascular risk factors for thrombosis. Arteriographic evaluation in all cases revealed distal abnormalities in the arteries of feet, legs, forearms, and hands resembling those of Buerger's disease. A collateral circulation sometimes with opacification of the vasa nervorum was noted. In some cases, arterial proximal atherosclerotic lesions and venous thrombosis were observed. All patients were moderate tobacco smokers and regular cannabis users. Despite treatment with ilomedine and heparin in all cases, five amputations were necessary in four patients. The vasoconstrictor effect of cannabis on the vascular system has been known for a long time. It has been shown that delta-8- and delta-9-tetrahydrocanabinols may induce peripheral vasoconstrictor activity. Cannabis arteritis resembles Buerger's disease, but patients were moderate tobacco smokers and regular cannabis users. These cases show that prolonged use of cannabis could be an additive risk factor for juvenile and young adult arteritis. Cannabis arteritis is a forgotten and severe occlusive vascular disease occurring in young adults. Search for cannabis use may be an important tool for a better knowledge of arteritis in young smokers.

Relationship between parity and clinical and biological features in patients with systemic sclerosis.

OBJECTIVE: To assess the influence of parity on the clinical and biological features of systemic sclerosis (SSc). METHODS: We recorded the following clinical and biological data of 100 consecutive women with SSc: age, disease duration before diagnosis, cutaneous extension of sclerosis according to LeRoy's classification, pulmonary involvement, and antinuclear antibodies. We compared these features to the number and sex of children who were born before SSc onset. Date of birth of the first children was systematically recorded. RESULTS: Patients with limited SSc had more children before SSc onset than patients with diffuse SSc (2.4 +/- 1.8 vs 1.7 +/- 1.5; p < 0.05). The interval between first birth and SSc onset was shorter for patients with limited SSc than for patients with diffuse SSc (11.0 +/- 9.9 vs 23.5 +/- 14.5 yrs; p < 0.01). Patients with pulmonary fibrosis had more children than patients without pulmonary fibrosis (2.5 +/- 1.9 vs 2.0 +/- 1.6; p < 0.05). Age at first birth was significantly higher when the child was a girl than a boy (26.8 +/- 7.5 vs 22.9 +/- 5.3 yrs; p < 0.05). The interval between the first birth and SSc onset was shorter when the child was a girl than a boy (16.2 +/- 9.6 vs 25.4 +/- 13.4 yrs; p < 0.05). CONCLUSION: Pregnancy related microchimerism could be preferentially associated with limited SSc and pulmonary fibrosis. Microchimerism may be facilitated in cases in which the fetus is female.

Polymyositis and dermatomyositis: short term and longterm outcome, and predictive factors of prognosis.

OBJECTIVE: To assess short term and longterm outcome of polymyositis (PM) and dermatomyositis (DM), and predictive variables of PM/DM course. METHODS: The medical records of 77 consecutive patients with PM/DM were reviewed. The criteria for PM/DM diagnosis were based upon Bohan and Peter criteria. RESULTS: Thirty-one patients (40%) achieved remission of PM/DM, whereas 33 (43%) improved and 13 (17%) worsened their clinical status. Short term recurrences of PM/DM (during tapering of therapy) occurred in 36 patients and longterm recurrences (after discontinuation of therapy) in 9 patients. PM/DM were associated with both decreased functional status and quality of life at longterm followup: (1) only 52% of patients considered to be in remission experienced a return to previous normal activities; and (2) 45% of the other patients with nonremitting PM/DM still had a marked reduction of activities (as shown by the disability scale of the Health Assessment Questionnaire). Overall mortality was as high as 22%, and the main causes of death were cancer and lung complications. Factors associated with PM/DM remission were younger age and shorter duration of clinical manifestations prior to therapy initiation. Variables associated with poor outcome of PM/DM were older age, pulmonary and esophageal involvement, and cancer. CONCLUSION: Our series shows both high morbidity and mortality related to PM/DM, emphasizing that management of PM/DM patients at an early stage is required. Lung complications (i.e., aspiration pneumonia due to PM/DM related esophageal dysfunction and ventilatory insufficiency) were one of the main causes of death in our series, indicating that investigating for subclinical esophageal and lung impairment should become an integral part of initial PM/DM evaluation. The presence of poor prognostic factors should prompt both close followup and aggressive therapy in patients with PM/DM.
