Education, employment, absenteeism, and work disability in women with systemic lupus erythematosus.

OBJECTIVES: To study education, employment, absenteeism, and work disability (WD) in women with systemic lupus erythematosus (SLE) compared to population controls. METHOD: The study included 181 women of working age with SLE (mean age 44.0 years, disease duration 12.7 years) and 549 female population controls matched for age living in the same metropolitan area of Helsinki. Data regarding education, employment, absenteeism, and WD in patients and controls were obtained by questionnaire and personal interview. RESULTS: Basic education, vocational, or academic degrees and occupational categories in patients with SLE were similar to those in controls. In total, 62% of the patients were employed, compared to 77% of the controls (p < 0.001). During the preceding 12 months, employed SLE patients had been on sick leave for 25.4 days vs. 10.2 days in controls (p < 0.001). Subjective work ability regarding physical and mental demands of the job were lower in SLE patients than in controls (p < 0.001 and p = 0.036, respectively). The rate of permanent WD, defined as receiving disability benefits, was 34.3% in SLE patients vs. 10.3% in controls (p < 0.001). Cumulative WD due to SLE 5, 10, and 20 years after the clinical diagnosis was 13, 22, and 47%, respectively. CONCLUSIONS: SLE does not seem to affect educational achievements and the employment rate for SLE patients is reasonably high. Absenteeism and work disability are, however, 2-3 times more common than in controls. Less than half of the patients were on permanent disability pension due to SLE 20 years after diagnosis of the disease.

Frequency of and risk factors for symptomatic bone fractures in patients with systemic lupus erythematosus.

OBJECTIVES: To study risk factors for symptomatic bone fractures in patients with systemic lupus erythematosus (SLE) and to compare the frequency of fractures between SLE patients and population controls. METHOD: The study included 222 SLE patients [mean age 47.0 years, disease duration 13.1 years, 204 (92%) women] and 720 population controls living in the metropolitan area of Helsinki. The history of symptomatic bone fractures in SLE patients and controls was recorded by interview, and demographic and clinical data of SLE patients were obtained by interview, clinical examination, and chart review. RESULTS: A history of at least one symptomatic bone fracture was recorded in 93 (42%) of all 222 patients with SLE. The risk of any fracture in 204 women with SLE compared to controls was 1.8 [95% confidence interval (CI) 1.3-2.4] and fractures in the ankle, hip, and vertebral column were more common than in female controls, with odds ratios (ORs) of 2.0 (95% CI 1.1-3.7), 5.1 (95% CI 1.2-21.5), and 4.0 (95% CI 1.8-8.6), respectively. In 18 men with SLE, compared to male controls, no difference in the frequency of fractures was observed (OR 0.7, 95% CI 0.3-2.0). Risk factors for bone fractures in women with SLE were age (p = 0.008), comorbidity (p = 0.050), and the duration of corticosteroid use (p = 0.025). CONCLUSIONS: Symptomatic bone fractures, especially in the ankle, hip, and vertebral column, are common in women with SLE. Special attention should be paid to preventing fractures in elderly female patients with comorbidities and a long duration of corticosteroid use.

The effect of ascorbic acid during biopsy and cryopreservation on viability of bovine embryos produced in vivo.

Multiple ovulation embryo transfer (MOET) is used to make more rapid progress in animal breeding schemes. On dairy farms, where female calves are more desired, embryo sex diagnosis is often performed before embryo transfer. Fresh transfers have been favored after biopsy due to cumulative drop in pregnancy rates following cryopreservation. The aim of this study was to explore whether exposure to ascorbic acid (AC) during biopsy and freezing increases the viability of biopsied embryos after cryopreservation. Data on presumptive pregnancy and calving rates of biopsied and cryopreserved/overnight-cultured embryos were gathered. Results showed differences in presumptive pregnancy rates between the groups: 45% for both biopsied-cryopreserved groups (control and AC), 51% for biopsied-overnight-cultured embryos and 80% for intact-fresh embryos. Differences between the groups were also apparent in calving rates: 22% for biopsied-cryopreserved control embryos, 31% for biopsied-cryopreserved AC-embryos, 23% for biopsied-overnight-cultured embryos and 63% for intact-fresh embryos. It is concluded that manipulated embryos are associated with lower presumptive pregnancy and calving rates compared with intact-fresh embryos. The highest calving rates for groups of manipulated embryos were achieved in the AC-group. Therefore, addition of AC can be recommended if biopsy is combined with freezing before transfer.

Reproductive health in women with systemic lupus erythematosus compared to population controls.

OBJECTIVE: To study the reproductive health history in women with systemic lupus erythematosus (SLE) compared to population controls. METHODS: A total of 206 female SLE patients were interviewed regarding demographic and disease data, menstruation, use of contraception and hormone replacement therapy (HRT), infertility, and pregnancies. The control group consisted of 1037 women from the general population of similar age and socioeconomic status living in the same region. RESULTS: In SLE women compared to population controls, mean age at menarche (13.3 vs. 13.2 years) and frequency of infertility (16% vs. 16%) were similar but menopause occurred earlier (44.9 vs. 46.8 years, p = 0.01). Current use of oral contraceptives (OCs) was less common than in controls [18% vs. 28%, odds ratio (OR) 0.55, 95% CI 0.3-1.0] while previous use of progesterone-containing intrauterine devices (IUDs) was more common (13% vs. 5%, OR 3.2, 95% CI 1.9-5.4). Current use of HRT was similar (22% vs. 21%) but SLE patients had started the use earlier (43.2 vs. 47.1 years, p = 0.003). Mean number of pregnancies was lower in SLE patients compared to controls (2.3 vs. 2.5, p = 0.046) and in lupus nephritis patients compared to SLE patients without nephritis (1.9 vs. 2.5, p = 0.01). No difference was found in the occurrence of spontaneous and induced abortions compared to controls, but pregnancy-associated complications were more common in SLE women. CONCLUSION: When compared to population controls women with SLE are normally fertile, use less OCs and more IUDs, have earlier menopause and use HRT as frequently. Family size is reduced, especially in lupus nephritis patients, and pregnancy-associated complications are more common.

Antibodies to amino acid 200-239 (p200) of Ro52 as serological markers for the risk of developing congenital heart block.

Maternal autoantibodies to the p200-epitope of Ro52 have been suggested to correlate with development of congenital heart block. The aim of the present study was to evaluate the clinical relevance and predictive value of p200-antibodies in high-risk pregnancies. Sera from 515 Finnish, Swedish and American women were included in the study. Sera originated from 202 mothers with an infant affected by second- or third-degree atrioventricular block (AVB), 177 mothers with rheumatic disease having infants with normal heart rate and female blood donors (n = 136). A novel serological assay for Ro52 p200-antibodies with intra- and inter-assay variability of 3% and 3.8% respectively was developed. Mothers of children affected by AVB II-III had significantly higher p200-antibody levels than mothers with rheumatic disease having children with normal heart rate (P < 0.001). In the Swedish cohort, a distinction between foetuses with normal conduction, AVB I, AVB II and III was possible. A significant difference in anti-p200 levels between AVB I and AVB II-III groups compared with foetuses with normal conduction (P < 0.05 and P < 0.01) was observed. Using p200-antibodies as a second step analysis in Ro52-positive pregnancies increased the positive predictive value for foetal cardiac involvement (AVB I, II or III) from 0.39 (0.27-0.51) to 0.53 (0.37-0.68). In conclusion, Ro52 p200-antibodies may occur in women with unaffected children, but levels are significantly higher in mothers of children with congenital heart block and are suggested as a relevant marker in evaluating the risk for foetal AV block.

Association of tumour necrosis factor a, b and c microsatellite polymorphisms with clinical disease activity and induction of remission in early rheumatoid arthritis.

OBJECTIVE: To study the associations of tumor necrosis factor (TNF) a, b and c microsatellite markers with 1) the clinical disease activity and 2) the induction of remissions in patients with early rheumatoid arthritis (RA) treated with two treatment strategies. METHODS: In the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial of two years, 195 patients with recent-onset RA were randomly assigned to receive either a combination (COMBI) (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) or a single (SINGLE) (initially sulphasalazine with or without prednisolone) disease modifying antirheumatic drug (DMARD) therapy. TNF a, b and c microsatellite and HLA-DRB1 typings were carried out in 165 (79 COMBI; 86 SINGLE) study completers. RESULTS: At baseline the 28 joint disease activity scores (DAS28) of the patients positive for TNFa2, a13 or b1 microsatellite markers were significantly higher than in the other patients. In the SINGLE patients the DAS28 improved comparably in patients with (n = 31) or without (n = 53) the TNFb1 marker (NS), while the DAS28 of the TNFb1-positive COMBI patients (n = 22) improved significantly more than that of the TNFb1-negative cases (n = 57) (p = 0.014). Respective 31.8% (7/22) and 28.1% (16/57) of the COMBI patients with or without TNFb1 allele achieved remission at one year. The corresponding figure in SINGLE patients were 0% (0/31) and 20.8% (11/53) (p = 0.006). At two years the remission frequencies in the TNFb1+/TNFb1- patients in the COMBI and SINGLE were 50.0%/38.6% and 9.7%/22.6%, respectively. CONCLUSION: Early TNFb1+ RA patients have more active disease but respond more favourably to COMBI treatment than the patients without this microsatellite allele. The finding may be of clinical relevance for the choice of DMARDs in early RA.

Anti-nucleosome antibodies in the diagnosis of systemic lupus erythematosus.

OBJECTIVE: To study the prevalence and diagnostic significance of antibodies against nucleosomes in patients with systemic lupus erythematosus (SLE) as compared to five anti-nuclear antibody (ANA) assays. METHODS: The study included 305 patients with SLE, 125 patients with other autoimmune rheumatic diseases, and 415 healthy controls. Anti-nucleosome antibodies were measured by an enzyme-linked immunosorbent assay (ELISA) and ANA by immunofluorescence (IF) using Hep-2 cells. Anti-double-stranded DNA (anti-dsDNA) antibodies were measured by three commercial ELISAs and by IF using Crithidia luciliae as antigen. RESULTS: Compared to three ELISAs for anti-dsDNA, the anti-nucleosome assay was less sensitive (30% vs. 29-69%) but equally specific (90% vs. 77-95%) for SLE. The most sensitive test was ANA (76%), and the least sensitive was Crithidia (13%). The correlations between the different assays were good (p < 0.001 for all comparisons). CONCLUSION: The anti-nucleosome antibody assay does not offer additional information compared to conventionally used anti-dsDNA tests in the differential diagnosis of SLE.

Serum soluble interleukin-2 receptor predicts early remission in patients with recent-onset rheumatoid arthritis treated with a single disease-modifying antirheumatic drug.

OBJECTIVE: To study the value of baseline serum levels of circulating soluble interleukin-2 receptor (sIL-2R) and soluble E-selectin as predictors of early remission in patients with recent-onset rheumatoid arthritis (RA) receiving a single disease-modifying anti-rheumatic drug (DMARD) (SINGLE) or therapy with a combination of DMARDs (COMBI). METHODS: Baseline (n = 157) serum samples originate from the FIN-RACo (FINnish Rheumatoid Arthritis Combination therapy) trial, in which 195 patients with early and clinically active RA were randomly assigned to receive either SINGLE (initially sulfasalazine) with or without prednisolone, or COMBI therapy (sulfasalazine, methotrexate, hydroxychloroquine, and prednisolone). Of the samples, 76 were from SINGLE patients and 81 from COMBI patients. sIL-2R was measured by automated immunoassay analyzer and sE-selectin by enzyme-linked immunosorbent assay. RESULTS: At six months, 7 (9% [95% CI: 4 to 18]) SINGLE and 19 (23% [95% CI: 15 to 34]) COMBI patients were in remission. In multivariate logistic regression analysis, sIL-2R <442 U/ml and COMBI therapy were the only predictors of remission. The area under receiver operating characteristic curve for sIL-2R level was 0.86 (95% CI: 0.62 to 0.95) in SINGLE and 0.57 (95% CI: 0.42 to 0.71) in COMBI (p = 0.006). In SINGLE, the optimal cut offpoint was 442 U/ml, lower levels predicting remission with sensitivity of 83% (95% CI: 73% to 91%) and specificity of 86% (95% CI: 42% to 100%). Likelihood ratio for positive test was 5.9 (95% CI: 1.6 to 32.8). In multivariate logistic regression analysis, sIL-2R <442 U/ml and COMBI therapy were the only predictors of remission. CONCLUSION: Low baseline serum sIL-2R level predicts early remission of patients with active early RA treated with a single DMARD.

The association of antibodies to cardiolipin, beta 2-glycoprotein I, prothrombin, and oxidized low-density lipoprotein with thrombosis in 292 patients with familial and sporadic systemic lupus erythematosus.

OBJECTIVE: To determine the prevalence of antibodies to phospholipid-binding plasma proteins (aPL) and to oxidized low-density lipoprotein (OX-LDL), and to study the association of these antibodies with thrombosis and coronary heart disease (CHD) in patients with systemic lupus erythematosus (SLE). METHODS: Clinical data and sera from 89 Finnish patients with familial and 203 with sporadic SLE were available for the study. Enzyme-linked immunosorbent assays (ELISA) were used for antibody determination. RESULTS: The occurrence of thrombosis in our SLE patients was 13.7% (40/292) and of clinically diagnosed CHD was 1.4% (4/292). All antibody assays, except IgM-aCL, were significantly associated with thrombosis. IgG-aCL alone or in combination with anti beta 2-GPI or with anti OX-LDL were reasonably sensitive (38%, 48%, and 58%, respectively) and specific (87%, 80% and 72%, respectively) for a history of thrombosis. A high risk of arterial thrombosis (TIA or stroke) was associated with positivity of IgG-aCL, anti beta 2-GPI, and anti-prothrombin. Venous thrombosis was significantly associated with all other assays except IgM-aCL and anti-prothrombin. No test correlated with CHD, but the number of affected patients was small. There were three multiplex SLE families with two patients having a history of thrombosis: no consistent pattern of aPL or anti OX-LDL was found in these patients. CONCLUSION: IgG-aCL alone or in combination with anti beta 2-GPI or anti OX-LDL are sensitive and specific tests for detecting SLE patients at increased risk of thrombosis. The aetiopathogenesis of thrombosis in familial SLE appears to be multifactorial.

Anti-telomere antibodies in systemic lupus erythematosus (SLE): a comparison with five antinuclear antibody assays in 430 patients with SLE and other rheumatic diseases.

OBJECTIVE: To investigate the prevalence and diagnostic significance of antibodies against telomeric DNA in systemic lupus erythematosus (SLE) and other autoimmune rheumatic diseases, and to make comparisons with five conventional anti-DNA or anti-nuclear antibody (ANA) assays. METHODS: Antibodies to telomeres, which are highly repetitive sequences of DNA (TTAGGG/CCCTAA) at the end of eukaryotic chromosomes, were measured by an enzyme linked immunosorbent assay (ELISA) in 305 patients with SLE and 125 patients with other autoimmune rheumatic diseases (78 rheumatoid arthritis, 32 primary Sjögren's syndrome, eight mixed connective tissue disease, seven miscellaneous rheumatic diseases). Other assays used were two commercial ELISA assays for anti-dsDNA using calf thymus as antigen, Crithidialuciliae immunofluorescence, and radioimmunoassay (RIA) for anti-dsDNA and immunofluorescence using Hep-2 cells for ANA. RESULTS: The prevalence of anti-telomere in SLE was 60%, v 5% in rheumatoid arthritis and 18% in other autoimmune rheumatic diseases. Specificity of anti-telomere for SLE was 91%; positive and negative predictive values were 95% and 46%, respectively. For anti-dsDNA by two ELISA assays using calf thymus as antigen, sensitivities were 69% and 29% and specificities 66% and 96%, respectively. Other anti-dsDNA assays had low sensitivities (RIA 43%, Crithidia immunofluorescence 13%). The association of anti-telomere with a history of nephritis in patients with SLE was stronger (p = 0.005) than by any other assay (p = 0.006-0.999). The correlations between the different assays were good (p<0.001 for all comparisons). CONCLUSIONS: The new ELISA for anti-telomere antibodies using standardised human dsDNA as antigen is a sensitive and highly specific test for SLE.

Relationship of maternal autoimmune response to clinical manifestations in children with congenital complete heart block.

OBJECTIVE: To study the autoimmune response in mothers of children with congenital heart block (CHB) diagnosed at different ages and with different clinical manifestations. PATIENTS AND METHODS: Clinical data and sera for the determination of immunological tests were available from 104 mothers of 113 children born between 1950 and 2000 and diagnosed with CHB before the age of 16 y. Prenatal diagnosis was performed in 74 (65%) children of 65 mothers, and 39 (35%) children had postnatal diagnosis of CHB. Maternal antibodies to 52 kd and 60 kd SS-A, and to 48 kd SS-B were determined by time-resolved fluoroimmunoassay (TR-FIA) and to antinuclear antibodies (ANA) by immunoflurescense (IF). RESULTS: Out of the 65 mothers of children with in utero diagnosed CHB, 88% had antibodies to 52 kd SS-A and 83% had ANA. Antibodies to 60 kd SS-A and 48 kd SS-B were less frequently present, in 48% and in 54% of the mothers, respectively. Seven (11%) of the mothers were negative by all immunoassays. Of the 13 mothers of children with in-infancy diagnosed CHB, one mother had high-titer ANA. After 1 y of age, CHB was diagnosed in 26 children; at 1 to 6 y in 16 and after 7 y in 10 children; 1/16 and 1/10 patients had positive antibodies. In all twin pregnancies (n = 4) and in all families with recurring cases of CHB (n = 5), maternal antibodies were positive in at least one assay. The titer of 48 kd anti-SS-B antibodies was significantly higher in children with cutaneous neonatal lupus (98.1 vs 41.0; p = 0.02). All mothers whose children died before the age of 4 y (n = 8) and 85% (11/13) of mothers whose children developed cardiomyopathy had elevated antibody titers in at least one assay. However, we could not find any prognostic value of maternal antibody levels or specificities on the clinical outcome of the children with CHB. CONCLUSIONS: Although rare, late detection or postnatal progression of CHB in antibody-mediated CHB should be taken into consideration. Maternal antibody levels or specificities have prognostic effect neither on the clinical outcome of the child with CHB nor on the risk of reappearance in the same family.

Peptidylarginine deiminase, the arginine to citrulline converting enzyme, is frequently recognized by sera of patients with rheumatoid arthritis, systemic lupus erythematosus and primary Sjögren syndrome.

OBJECTIVE: Antibodies to citrulline-containing epitopes of filaggrin are highly specific for rheumatoid arthritis (RA). We studied whether the enzyme peptidylarginine deiminase (PAD), responsible for the post-translational modification of peptide-bound arginine residues to citrulline, constitutes an antigen for patients with RA. METHODS: IgG antibodies to PAD were measured by enzyme-linked immunosorbent assay (ELISA) in sera from patients with RA, systemic lupus erythematosus (SLE), primary Sjögren syndrome (pSS), multiple sclerosis (MS) and healthy controls. RESULTS: Compared to healthy controls, raised levels of IgG antibodies to PAD were found in 50 of 57 recent-onset RA patients (88%) and in 40 (70%) of the same 57 patients 3 years later (p<0.0001 for both comparisons). Eleven of 51 (22%) patients with RA of long duration, 19/43 (44%) patients with SLE and 16/19 (84%) patients with pSS, but none of 20 patients with MS, had elevated anti-PAD levels. CONCLUSION: The arginine-citrulline converting enzyme PAD was recognized as a new antigen against which patients with inflammatory rheumatic diseases frequently show IgG class antibodies.

Pregnancy and lupus nephritis.

Family planning and pregnancy are important and usually problematic issues for a young woman with lupus nephritis. Moderate renal insufficiency and previous use of alkylating cytotoxic drugs are associated with decreased fertility. Oral contraceptives containing synthetic estrogens are contraindicated in women with active lupus nephritis, uncontrolled hypertension, history of thromboembolic diseases or high levels of antiphospholipid antibodies. Mild flares of systemic lupus erythematosus (SLE) are common during pregnancy, severe renal flares and permanent impairment of renal function are uncommon. The outlook of pregnancy for women with lupus nephritis is usually favourable if the disease (both renal and nonrenal) has been quiescent for at least 6 months before pregnancy, and if, at conception, serum creatinine is less than 140 micromol/l, proteinuria less than 3 g/24 h and blood pressure controlled. The risk of fetal loss is, however, at least 2-3 times higher than in the normal population and pre-eclampsia, prematurity and fetal growth retardation frequently complicate these pregnancies. Especially poor fetal outcome is associated with antiphospholipid antibodies. Pregnancies in women with lupus nephritis require intense fetal and maternal surveillance.

Familial systemic lupus erythematosus in Finland.

OBJECTIVE: To perform a cross sectional nation-wide clinical study of familial systemic lupus erythematosus (SLE) in Finland. METHODS: We sought to identify all Finnish families in which at least 2 members satisfied the classification criteria for SLE. About 1,200 patients with SLE (80-85% of all patients attending Finnish hospitals) were contacted. Personal and/or phone interviews and examination of medical records were used to verify the diagnoses. A comparison of clinical characteristics was made between familial cases of SLE and matched sporadic controls. RESULTS: We identified 53 multiplex families with 113 SLE patients. Forty-six families had 2 affected members and 7 families had 3 affected members. There were 3 pairs of monozygotic female twins and one pair of dizygotic twins of the opposite sex concordant for SLE. Eleven (9.7%) of the 113 familial cases of SLE were male. No differences were found in the clinical presentation of SLE between familial and sporadic cases (sex, age at onset, major clinical manifestations, and common laboratory tests). The incidence of familial SLE was approximately 4-5%. CONCLUSION: Our study shows that familial and sporadic SLE are not different disease entities; this means that we can extrapolate the results of future genetic analyses in multiplex SLE families to all patients with SLE.

Long-term outcome of mothers of children with isolated heart block in Finland.

OBJECTIVE: To study the long-term outcome of mothers of children with isolated heart block in a defined population. METHODS: We reviewed the Finnish hospital registries for patients born between 1950 and 1999 who had been diagnosed as having isolated heart block before the age of 15 years. We identified 101 children with isolated congenital heart block (CHB) and 55 with isolated heart block detected after the newborn period. Eighty-three (91%) of the 91 mothers of children with CHB and 48 (87%) of the 55 mothers of children with heart block detected after the newborn period were studied according to a protocol defining clinical characteristics (mean 9.9 years, range 0-49 years, and mean 22.9 years, range 4-47 years after the index delivery, respectively). Maternal survival was compared with survival in an age-matched population of normal Finnish women. RESULTS: Before the index delivery, 29 (37%) of the 78 surviving mothers of children with CHB had a self-reported clinical diagnosis of a chronic autoimmune disease, and 55 (71%) had had symptoms, signs, or abnormal laboratory findings suggesting an underlying subclinical disease. Of the 23 mothers who were completely asymptomatic before the index delivery, 10 (13% of the surviving mothers) remained so after a mean followup of 9.6 years (range 0-21 years). In mothers of children with CHB, clinical characteristics different from those of healthy mothers were photosensitivity, fatigue, dry eyes, and dry mouth. Forty-eight (58%) of these 83 mothers developed an autoimmune disease during followup. The most common diagnosis was primary Sjögren's syndrome (22 definite, 11 probable), followed by systemic lupus erythematosus (SLE). The standardized mortality ratio of mothers of children with CHB was 5.1, and 3 of the 5 deaths were associated with SLE. Mothers of children with heart block detected after the newborn period had similar symptoms and signs of autoimmune diseases as the healthy controls, and their standardized mortality ratio was 1.9. CONCLUSION: Primary Sjögren's syndrome, either definite or subclinical, is the predominant autoimmune disorder in mothers of children with CHB. Mothers of children with isolated heart block detected after the newborn period do not, as a group, have clinical features suggestive of autoimmune diseases.

Hormone replacement therapy in women with rheumatic diseases.

Hormone replacement therapy (HRT) for the treatment of menopausal symptoms and for the prevention of osteoporosis and cardiovascular diseases has clearly increased during the last decades. Women with rheumatic diseases, especially when using corticosteroids, are in a high risk of osteoporotic fractures and atherosclerotic disease, which cause significant morbidity and mortality in later life. In this review, the benefits and risks of HRT in postmenopausal women are reviewed in general and, in particular, in women with rheumatic diseases.

Short- and long-term outcome of children with congenital complete heart block diagnosed in utero or as a newborn.

OBJECTIVES: Few data are available in the literature regarding the long-term outcome of newborns with congenital complete heart block (CHB). The aims of this retrospective study were to assess neonatal morbidity and mortality, incidences of dilated cardiomyopathy (DCM), and associated heart defects, and to establish prenatal and postnatal factors that might predict adverse outcome in children with CHB. DESIGN AND SETTING: The cohort includes 91 infants with CHB diagnosed in 5 tertiary centers in Finland between 1950 and 1998. PATIENTS: Maternal connective tissue disease was evident in 89% of the patients. At birth, the median gestational age was 37.1 weeks, and the median weight was 2969 g. Of the 91 infants, 60 (66%) were girls and 7 (8%) were twins. RESULTS: Incidences of perinatal morbidity and mortality were 58% and 7%, respectively. The total mortality of CHB was 16%; 11 of 15 (73%) died during the first 12 months. Cumulative probability of survival at 10 years old was 82%. Pacing as a newborn was indicated in 48 of 90 cases (53%), and 36 received pacemakers at older ages. Cardiac defects not causally related to CHB were found in 38 of 90 patients (42%), of whom 22 were operated on. DCM was found in 21 (23%), of whom 13 died. During the follow-up, among 75 survivors with a median age of 9 years, 54 (72%) are free from symptoms. Poor outcome defined as clinically or pathologically evident congestive DCM was associated with intrauterine hydrops, low fetal and neonatal heart rate, low birth weight, male sex, and neonatal problems attributable to prematurity or neonatal lupus. CONCLUSIONS: Despite early pacing, CHB carries high mortality during the first 12 months of life. High incidences of DCM and associated heart defects indicate close echocardiographic monitoring of all children with CHB.

Comparison of combination therapy with single-drug therapy in early rheumatoid arthritis: a randomised trial. FIN-RACo trial group.

BACKGROUND: The treatment of rheumatoid arthritis should aim at clinical remission. This multicentre, randomised trial with 2-year follow-up sought evidence on the efficacy and tolerability of combination therapy (sulphasalazine, methotrexate, hydroxychloroquine, and prednisolone) compared with treatment with a single disease-modifying antirheumatic drug, with or without prednisolone, in the treatment of early rheumatoid arthritis. METHODS: 199 patients were randomly assigned to two treatment groups. 195 started the treatment (97 received combination and 98 single drug therapy). Single-drug therapy in all patients started with sulphasalazine; in 51 patients methotrexate was later substituted. Oral prednisolone was required by 63 patients. The primary outcome measure was induction of remission. Analyses were intention to treat. FINDINGS: 87 patients in the combination group and 91 in the single-therapy group completed the trial. After a year, remission was achieved in 24 of 97 patients with combination therapy, and 11 of 98 with single-drug therapy (p=0.011). The remission frequencies at 2 years were 36 of 97 and 18 of 98 (p=0.003). Clinical improvement (American College of Rheumatology criteria of 50% clinical response) was achieved after 1 year in 68 (75%) patients with combination therapy, and in 56 (60%) using single-drug therapy (p=0.028), while at the 2-year visit 69 and 57 respectively (71% vs 58%, p=0.058) had clinically improved. The frequencies of adverse events were similar in both treatment groups. INTERPRETATION: Combination therapy was better and not more hazardous than single treatment in induction of remission in early rheumatoid arthritis. The combination strategy as an initial therapy seems to increase the efficacy of the treatment in at least a proportion of patients with early rheumatoid arthritis.
