[more] To describe the evolution of lung function in a cohort of rheumatoid arthritis (RA) patients with interstitial lung disease (ILD) treated according to the medical judgment of attending physicians. Retrospective cohort of RA patients with ILD, defined by a restrictive pattern in lung function tests and evidence of ILD in high resolution computed tomography (HRCT). Patients had an assessment of lung function including spirometry, diffusing capacity for carbon monoxide (DLCO), and HRCT. At a minimum of 4 months of follow up, a second assessment of lung function was done. All patients received a high dose of prednisone (1mg/kg/day) scheme for 6 weeks with a reduction scheme ending with a dose of 10mg/day of prednisone at about 6-8 months of follow up. Methotrexate was used in 18/40 (45%) patients and leflunomide or azathioprine or both were indicated in 22/40 (55%). Forty patients were identified. An indeterminate pattern with diffuse ground glass and reticulation images (50%) was the most prevalent pattern on HRCT scans. At a minimum of 4 months of follow up, an improvement in basal FVC values was observed (median (IQR)) 1.47 Lts. (0.99-1.91) vs 1.66 Lts. (1.37-2.1)), P<0.004. Patients with lower Kazerooni scores for fibrosis (<0.47) had a better improvement in the FVC values. Patients with RA and ILD may have an improvement in the FVC after a treatment with high doses of corticosteroids and disease modifying antirheumatic drugs (DMARDs).

Anti TNF-α agents may have a role in the treatment of Takayasu's arteritis and probably in giant cell arteritis. In Kawasaki's disease, infliximab is an option in subjects with intravenous immunoglobulin-resistant disease. Anti TNF-α cannot be recommended to treat ANCA-associated vasculitis. Anti-T lymphocyte globulin and alemtuzumab could have a role in the treatment of ANCA associated vasculitis, although current information about these two biological treatments comes from conventional resistant treatment cases, so the high incidence of complications and relapses observed with these treatment may be intrinsic to the severity of the disease and not related to the biological agents.

Current smoking status is associated to a non-ACR 50 response in early rheumatoid arthritis. A cohort study.
Clinical rheumatology. 05/2011; 30(12):1589-93.

[more] The purpose of this study is to determine factors associated with a non-ACR 50 response at 6 months of follow-up, in a cohort of patients with early rheumatoid arthritis (RA). Early RA patients (symptom duration <1 year), treated with the same combination treatment (methotrexate and sulfasalazine), were included. Demographic characteristics of the patients including current smoker status (defined as a patient that smokes at least one cigarette per day), years of formal education, a 28-joint count for swelling and tenderness were registered. A basal HAQ questionnaire, visual scales for global assessment, and pain were answered by all patients, and a CDAI basal score was calculated. The ACR 50 response was determined at 6 months follow-up. Multivariable logistic regression analysis was used to calculate adjusted ORs. Two hundred twenty-five patients were evaluated, but only 144 had a complete follow-up, 43% of the latter did not reach an ACR 50 response. The only factor associated with this outcome was current smoking (OR 3.58, P < 0.008, 95% CI 1.23-11.22). Low level of formal education (≤6 years) had a tendency towards a statistical difference (P < 0.08). After controlling with low level of formal education, sex, age in years, and CDAI baseline value with multivariable logistic regression analysis, current smoking status had an adjusted OR of 3.91 (P < 0.009, 95% CI 1.41-10.81). Smoking is associated with a non-ACR 50 response in early rheumatoid arthritis in patients treated with a combination therapy with methotrexate and sulfasalazine.

[more] Morphology in chronic HP is characterized by bronchiolocentric mononuclear inflammation, poorly formed granulomas and variable degree of fibrosis. However, recent findings suggest that this disease may present different pathologic patterns. In this study we evaluated the clinical behavior and survival of patients with pigeon breeder's disease according to the pathologic pattern. One-hundred ten biopsies were classified as "typical" (n = 58), non-specific interstitial pneumonia (NSIP)-pattern (n = 22), usual interstitial pneumonia (UIP)-like (n = 10), mixed pattern (n = 9), organizing pneumonia (OP)-pattern (n = 3), airway-centered interstitial fibrosis (ACIF)-pattern (n = 3), and non-classified (n = 5). Clinical features and survival were compared between patients with "typical", NSIP, and UIP patterns. There were no statistical differences between the groups in age, gender, time of symptoms, smoking, clubbing, and PaO(2). By the one-way ANOVA test we found differences in the percent of lymphocytes in bronchoalveolar lavage (BAL; p < 0.002) and in the forced vital capacity (p < 0.05) between the 3 groups. After Bonferroni correction the difference in BAL lymphocytes remained significant among the UIP-like and the typical pattern (36.1 ± 22.9 versus 64.6 ± 20.9, p = 0.001). UIP-like patients exhibited the worst survival rate (HR: 4.19; 95% CI: 1.66-14.47; p < 0.004) while NSIP-like pattern showed the best survival (HR: 0.18; 95% CI: 0.04-0.82; p < 0.03). Multivariate Cox regression analysis revealed that patients with a UIP-like pattern retained a significantly worse survival (HR: 3.4 (IC 95%: 1.15-10.29; p < 0.03), and mortality for the NSIP group was best and approached statistical significance (p = 0.07). These findings demonstrate that a variety of histopathologic and imaging patterns are seen in PBD, and the presence of a UIP-like pattern confers the worst prognosis.

[more] BACKGROUND: In late March 2009, an outbreak of a respiratory illness later proved to be caused by novel swine-origin influenza A (H1N1) virus (S-OIV) was identified in Mexico. We describe the clinical and epidemiologic characteristics of persons hospitalized for pneumonia at the national tertiary hospital for respiratory illnesses in Mexico City who had laboratory-confirmed S-OIV infection, also known as swine flu. METHODS: We used retrospective medical chart reviews to collect data on the hospitalized patients. S-OIV infection was confirmed in specimens with the use of a real-time reverse-transcriptase-polymerase-chain-reaction assay. RESULTS: From March 24 through April 24, 2009, a total of 18 cases of pneumonia and confirmed S-OIV infection were identified among 98 patients hospitalized for acute respiratory illness at the National Institute of Respiratory Diseases in Mexico City. More than half of the 18 case patients were between 13 and 47 years of age, and only 8 had preexisting medical conditions. For 16 of the 18 patients, this was the first hospitalization for their illness; the other 2 patients were referred from other hospitals. All patients had fever, cough, dyspnea or respiratory distress, increased serum lactate dehydrogenase levels, and bilateral patchy pneumonia. Other common findings were an increased creatine kinase level (in 62% of patients) and lymphopenia (in 61%). Twelve patients required mechanical ventilation, and seven died. Within 7 days after contact with the initial case patients, a mild or moderate influenza-like illness developed in 22 health care workers; they were treated with oseltamivir, and none were hospitalized. CONCLUSIONS: S-OIV infection can cause severe illness, the acute respiratory distress syndrome, and death in previously healthy persons who are young to middle-aged. None of the secondary infections among health care workers were severe. Copyright 2009 Massachusetts Medical Society.

[more] The objective of this study is to identify baseline factors associated with rheumatoid arthritis (RA) diagnosis at the end of 1-year follow-up in a cohort of patients with very recent onset arthritis. Incident cases with self-reported arthritis (</=12 weeks) referred by primary care physicians were assessed by a designated rheumatologist who predicted in those with >/=1 swollen joint the diagnosis of RA at the end of follow-up. Patients were regularly seen and diagnosed through follow-up by staff rheumatologists who were blind to diagnostic prediction. Of 119 referrals, 78 (65.5%; age 35.5 +/- 13.5 years; 69 females) were diagnosed at baseline as very recent onset arthritis (median duration 6 weeks (0-12 weeks)); of 75 patients completing 1-year follow-up, 51 (66.5%) were classified as RA; 12 (16%) had self-limited arthritis; and 13 (17.5%) other diagnoses. The characteristics of patients with RA as final diagnosis were polyarthritis, morning stiffness >/=1 h, high counts of swollen joints, and low frequency of systemic symptoms. Rheumatologist prediction of RA and anti-cyclic citrullinated peptide (anti-CCP) antibodies was strongly associated with RA as a final diagnosis in the logistic regression analysis. Sensitivity and specificity of the rheumatologist prediction were 94% and 74%, for anti-CCP antibodies, 56% and 96%; the combination of both variables had a specificity of 100% and a sensitivity of 53%, and a positive predictive value of 98%. The combination of RA as predicted diagnosis by a rheumatologist and anti-CCP antibodies is highly specific for RA diagnosis in patients with very early arthritis.

[more] OBJECTIVE: To determine in gout patients, the temporal relationship between the first gout attack and the diagnosis of metabolic syndrome (MS), its components and complications. SUBJECTS AND METHODS: We included consecutive gout patients attending 2 Rheumatology Departments from Spain (Hospital Universitario Reina Sofía) and México (Hospital General de México). Variables included demographic, clinical, and biochemical data: Hypertension, hypertriglyceridemia, low high density lipoproteins (HDL), obesity, hyperglycemia or diabetes, MS (Adult Treatment Pane III criteria), ischemic heart disease (IHD), and chronic renal failure (CRF). Age and date (year) of the diagnosis of first acute gout attack and associated diseases were obtained. RESULTS: Four hundred seven patients were included (96% men); mean age at onset, mean age at inclusion, and mean duration of the disease were 39.7 +/- 13, 52.5 +/- 13, and 13.7 +/- 9.9 years, respectively. In 90%, the first attack of gout preceded the diagnosis of features of MS, MS itself or its complications (CRF and IHD), 9.8% had previous diagnosis of at least 1 associated disease. At the time of the inclusion (mean, 13.7 years after the first attack), 93% had at least 1 associated disease. The most common were hypertriglyceridemia, 63%; obesity, 54%; hypertension, 45.6%; MS, 40%; hyperglycemia, 37%; low HDL, 17%; diabetes, 15%; CRF, 17%; and IHD, 6.6%. Although patients from the 2 Rheumatology Departments had several demographic and clinical differences, in both groups most of the patients (70% Hospital Universitario Reina Sofía and 95% Hospital General de México) had no diagnosis of any associated disease previous to first bouts and at inclusion most of them had the diagnosis of at least 1 associated disease. CONCLUSIONS: First attacks of gout may precede the diagnosis of metabolic abnormalities and associated diseases, and provids a unique opportunity to diagnose, prevent, and/or retard long-term complications in these patients.

[more] Background It has been suggested that the presence of emphysema modify the outcome of patients with idiopathic pulmonary fibrosis (IPF). In this study we compare clinical features, smoking history, pulmonary function, systolic pulmonary artery pressure (eSPAP), and mortality in IPF with emphysema vs IPF without emphysematous changes. Methods A cohort of 110 IPF patients was evaluated. Clinical data were collected from clinical charts. HRCT was examined by an expert blinded to clinical data and patients were classified in 2 groups: IPF with and without emphysema. Kaplan Meier method, Log Rank test and Cox regression model were used for statistical analyses. Results The prevalence of emphysema in the IPF cohort was 28% (31/110). IPF with emphysema was significantly associated with male gender (OR:18, 95% CI:2.7-773.7; p = 0.0003), and smoking (OR:3.8, CI:1.36-11.6; p = 0.04). Patients with IPF and emphysema had higher decrease of oxygen saturation during exercise (|gDSpO2 rest-exercise: (16.3 +/- 6.7 vs 13.5 +/- 4.6, p = 0.04) and higher fibrosis HRCT score (1.75 +/- 0.38 vs 1.55 +/- 0.36, p = 0.015), eSPAP (82 +/- 20 mm Hg vs 57 +/- 15 mm Hg, p < 0.0001), and mortality (median survival time of 25 months vs 34 months, p = 0.01) than IPF without emphysema. The Cox regression model showed that the two most important variables associated with mortality were FVC < 50% of predicted (HR: 2.6, 95% CI: 1.19-5.68, p = 0.016) and eSPAp >/= 75 mm Hg (HR: 2.25, 95% CI: 1.12-4.54, p = 0.022). Conclusions IPF patients with emphysema exhibit higher mortality compared with those with IPF without emphysema. This dire prognosis seems to be at least partially associated with the development of severe pulmonary arterial hypertension.

[more] The main objective of this study is to describe the presence of infections in patients with pulmonary haemorrhage and systemic lupus erythematosus. Patients with systemic lupus erythematosus and pulmonary haemorrhage were thoroughly evaluated in the first 48 hours with imaging plus bronchoscopy and bronchoalveolar fluid analysis. If needed, videoassisted thoracoscopy and lung biopsy were performed too. In all, search for bacterial, mycobacterial and fungal infections proceeded. Appropriate blood, bronchoalveolar fluid and tissue cultures were taken. Patients were treated with antibiotics and corticosteroids in case of infection. Otherwise, they received initial intravenous methylprednsiolone pulses for 3 days as standard therapy for pulmonary haemorrhage in systemic lupus erythematosus. Additional treatment with immunosuppressives was further decided by the treating physicians. Fourteen events in 13 patients were evaluated. In eight events (57%), an infection was demonstrated. Aetiological agents included Pseudomonas sp. and Aspergillus fumigatus. Four patients died, three of them because of the pulmonary infection and one because of cerebral haemorrhage secondary to severe systemic hypertension, 48 hours after methylprednisolone treatment. Patients with systemic lupus erythematosus and pulmonary haemorrhage have a high prevalence of infections. The influence of pulmonary haemorrhage in the setting of systemic lupus erythematosus needs further study to establish adequate treatment and to reduce the high mortality of this complication.

[more] To determine the cumulative incidence of severe organ involvement in Mexican patients with systemic sclerosis (SS) and diffuse scleroderma at 3 years from the onset of SS symptoms, and to compare itwith the cumulative incidence observed in a cohort of white patients with SS. Patients with SS and diffuse scleroderma were evaluated within the first 2 years from the onset of SS symptoms and were included. An estimation of the cumulative incidence of severe involvement to the skin, kidney, heart, lungs, and gastrointestinal track at 3 years from the onset of SS symptoms was carried out. This cumulative incidence was compared with that of white SS patients with diffuse scleroderma, using the one sample test for a binomial proportion. Sixty-three patients were included. The cumulative incidence of severe involvement to the skin was 3.17% (2/63) (95% CI, 0.04%-11); kidney involvement in 4.17% (3/63) (95% CI, 0.99%-13.29%); heart involvement in 1.6% (1/63) (95% CI, 0.04%-8.5%); lung involvement in 11.11% (7/63) (95% IC, 4.5%-21.5%); and gastrointestinal involvement in 4.7% (3/63) (95% IC, 0.99%-13.3%).

[more] To review the differences in the epidemiology, clinical manifestations, and severity of systemic sclerosis in different ethnic groups. This review considers only limited and diffuse forms of systemic sclerosis. The most relevant articles about ethnic differences in systemic sclerosis were selected. The information is presented in three sections: differences in the epidemiology of systemic sclerosis between ethnic groups; differences in clinical manifestations between ethnic group, and factors that may explain these differences. Of the different ethnic groups studied, whites have less incidence and prevalence of systemic sclerosis. Whites also have less frequency of inflammatory manifestations, and have a higher frequency of limited skin disease compared with other ethnic groups. These differences may result in the better survival of whites compared with no whites. The origin of these differences has not been discovered so far. Is probable that genetic and environmental factors may play a role in the expression of disease, producing the differences found among the ethnic groups.

[more] Patients with primary antiphospholipid syndrome (PAPS) may evolve to systemic lupus erythematosus (SLE), even many years later. This makes differentiation between primary and secondary antiphospholipid syndrome a difficult task. Studies in murine models of lupus have shown that the development of antinucleosome (anti-NCS) antibodies may occur from the early stages of life. We therefore hypothesize that anti-NCS antibodies could help predict development of SLE in patients with PAPS. We studied anti-NCS antibodies in 18 PAPS patients (15 female, three male), followed for a mean of 11 years to evaluate the potential development of SLE. When PAPS was diagnosed, nine patients were positive for anti-NCS antibodies. Six of them developed clinical manifestations of SLE. In contrast, none of the patients who were negative to anti-NCS antibodies developed it. These findings suggest that anti-NCS antibodies could help predict which patients with PAPS may eventually develop SLE.

[more] The objectives were to determine causes of consultation, hospitalization and outcome in a cohort of lupus patients in an emergency unit. Patients with systemic lupus erythematosus (SLE) who visited the emergency department for consultation from 1 September 1996 to 17 May 1997 were included in the study. They were evaluated during the visit by looking at 100 variables such as demographic, socioeconomic, clinical, therapeutical, behavioral, (compliance), emotional (Beck depression inventory), disease activity, (Mex-SLEDAI), disease severity (Lupus SDI), chronic damage (SLICC-ACR), and physician's and patient's global assessments of severity. All causes of consultation, hospitalization and outcome were registered. Descriptive statistics, univariate analysis and multiple logistic regression were used for analysis. Significance was set at the 0.05 level. 180 patients were included. 164 were female, mean age 31.7/11.39 y, mean Mex SLEDAI score 3.8, mean SLICC-ACR 1.3. Fever, poliarthralgia and abdominal pain were the main causes of consultation with 26, 25 and 18 cases each. 49 patients were hospitalized and these were statistically different than non-hospitalized patients in level of formal education (10.2 vs 11.8, P=0.03); compliance (7.6 vs 9, P=0.0001); malar rash (57% vs 82%, OR, 95% CI=0.28, 0.13-0.62, P=0.0008), chloroquine daily dose intake (45 vs 77 mg, P=0.04); disease severity in physician's global assessments (5.6 vs 2.1, P=0.0001) and Beck depression inventory (21 vs 16, P=0.01). Multiple logistic regression identified physician's global assessment, fewer ACR criteria and higher SLICC-ACR scores as the main variables associated with hospitalization. Five patients died; two with community acquired pneumonia, one with pancreatitis, multiple thromboses, and sepsis, one with pulmonary hemorrhage; and one with pulmonary thromboembolism. In conclusion, poor compliance, low level of formal education, severity, depression, lower ACR criteria and higher SLICC-ACR scores were important variables identified with hospitalization. Chloroquine use seemed to have a protective effect. Causes of death were related to infections and antiphospholipid syndrome.

[more] OBJECTIVE: To estimate the prevalence, burden of illness and help seeking behavior of musculoskeletal complaints and provide point prevalence estimates of osteoarthritis, low back pain, fibromyalgia, rheumatoid arthritis and gout among adult population in a suburban community in Mexico city. METHODS: Home survey of adults in a balanced and stratified sample validated against physical exam. Three trained interviewers applied a validated COPCORD core questionnaire. Subjects with pain (in the last seven days or ever) > or = 4 (0-10) and no trauma; or with current or past disability were evaluated preferably the same day by a trained clinician in a structured interview. A diagnosis using ACR criteria when available, recommendation or referral was provided as required. Analysis was based on descriptive statistics of participant characteristics, pain site and distribution, patterns of help seeking behavior. Point prevalence with 95% confidence intervals of most common diseases and associated disability rate. RESULTS: 1169 men and 1331 women were included. Pain in the last 7 days not associated with trauma was reported in 419 (17%) participants. The most common sites of involvement were knee (12.3%); low back (6.3%); ankles (6%) and shoulders (5.3%). The mean/SD pain score was 4.8/2.5. Thirteen percent of the total sample had some treatment. The general practitioner treated 72% of those; 75% perceived good efficacy with medications. Point prevalence estimates and 95% CI were: disability: 1.4% (0.0-1.9); osteoarthritis: 2.3% (1.7-2.9); fibromyalgia: 1.4 (1.0-2.0); low back pain: 6.3% (5.4-7.3); rheumatoid arthritis: 0.3% (0.1-0.6) and gout 0.4% (0.1-0.7). CONCLUSION: Pain in the last 7 days due to musculoskeletal disorders is 17% in this community. Medications were commonly prescribed. Point prevalence estimates of most common diagnoses was similar to other community surveys using COPCORD methodology but very different help seeking behavior.

We identified 17 cases of DAH, with the leading cause being ANCA associated vasculitis (41% of cases), followed by cases secondary to drugs (18%). In 35% of the cases, there was a failure in identifying an etiology. Six patients died (35%), the only factor associated with mortality was male gender 5/6 vs 3/11, p=0.05. The most frequent cause of alveolar hemorrhage was ANCA associated vasculitis. The mortality in DAH is about 35%, males seem to have a worse prognosis.
