ABSTRACT
OBJECTIVE: To analyze the effectiveness and safety of intravenous immunoglobulin (IVIG) given in routine care to patients with systemic sclerosis (SSc). METHODS: A retrospective multicenter observational study was conducted in SSc patients treated with IVIG. We collected data on epidemiological parameters and clinical outcomes. Firstly, we assessed changes in organ manifestations during IVIG treatment. Secondly, we analyzed the frequency of adverse effects. The following parameters were collected from baseline to the last follow-up: the patient's weight, modified Rodnan Skin Score (mRSS), modified manual muscle strength scale (MRC), laboratory test(creatine kinase(CK), hemoglobin and protein levels), The University of California Los Angeles Scleroderma Clinical Trials Consortium gastrointestinal tract 2.0 (UCLA GIT 2.0) questionnaire, pulmonary function tests, and echocardiography. RESULTS: Data were collected on 78 patients (82% females; 59% with diffuse SSc). Inflammatory idiopathic myopathy was the most frequent concomitant overlap disease (41%). The time since Raynaud's phenomenon and SSc onset were 8.8 ± 18 and 6.2 ± 6.7 years respectively. The most frequent IVIG indication was myositis (38/78), followed by gastrointestinal (27/78) and cutaneous (17/78) involvement. The median number of cycles given were 5. 54, 53 and 9 patients have been treated previously with glucocorticoids, synthetic disease-modifying antirheumatic drugs and biologic therapies respectively. After IVIG use we found significant improvements in muscular involvement (MRC ≥ 3/5 92% IVIG, p = 0.001 and CK levels from 1149 ± 2026 UI to 217 ± 224 UI, p = 0.02), mRSS (15 ± 12.4 to 13 ± 12.5, p = 0.015) and improvement in total score of UCLA GIT 2.0 (p = 0.05). None Anti-RNA polymerase III patients showed an adequate response in gastrointestinal involvement (0/7) in comparison with other antibodies (0 vs. 25, p = 0,039). Cardiorespiratory involvement remained stable. A total of 12 adverse events were reported with only one withdrawn due to serious adverse effect. CONCLUSIONS: this study suggest that IVIG may improve myositis, gastrointestinal and skin involvement in SSc patients treated in routine care and seems to have a good safety profile.

OBJECTIVE: To present the results of a one-year retrospective study that analyzed the clinical and epidemiological aspects of urological emergencies, which is not a negligible percentage of all hospital emergencies. METHODS: Data on all the urological emergencies of the emergency department of our hospital were collected during a one-year period by filling out a form that included sex, age, whether referred or not, disease, etc. RESULTS: There were 1504 urological emergencies; the urologist was required in 458 of these cases (30.45%). There were more men (837) than women (667). Patient ages ranged from 1-101 years (mean 53 years); a higher incidence was found for those aged 65 years. By age groups, there were more patients aged 61-80 years (575 patients). Most of the patients came to the hospital on their own initiative (1114) and 390 had been referred by their primary care physician. Renal colic (670 cases) was the most common diagnosis in both males and females, followed by cystitis, which was prevalent in the females (67.35%). Other conditions seen were urinary retention, hematuria, etc. CONCLUSIONS: There was a higher prevalence of males that consulted for urological conditions at the emergency department and there was a higher incidence in patients in the 6th and 7th decades of life, which is similar to the findings reported in other studies. Renal colic was the main reason for consultation for both genders and for all age groups, except those younger than 20 who presented more scrotal and penile involvement. Infective conditions involving the lower urinary tract (cystitis) and pyelonephritis were prevalent in the females. The large number of patients that were discharged from the emergency department and who consulted on their own initiative shows their confidence in the emergency services and that they could have been attended to at other health centers and did not have to come and unnecessarily strain the hospital emergency services.

OBJECTIVE: Enterocytozoon bieneusi is the most prevalent microsporidian causing chronic diarrhea in patients with acquired immunodeficiency syndrome. The current methods used for routine diagnosis of infections caused by microsporidia are based on microscopic detection of the microorganism spores in stained smears. We evaluated the usefulness of the polymerase chain reaction (PCR) technique as a tool to diagnose Enterocytozoon bieneusi infections, using the species-specific diagnostic primer pair EBIEF1/EBIER1 on stool samples that were also analyzed by optical microscopy. DESIGN: To perform PCR in such samples, we developed a novel protocol to obtain DNA free of PCR inhibitors. This protocol was based on disruption of spores using glass beads and overnight digestion with proteinase K; final purification was accomplished with the RapidPrep Micro Genomic DNA isolation Kit for Cells and Tissues (Pharmacia Biotech Inc, Piscataway, NJ). We also evaluated this approach on aliquots of a sample fixed in formalin from 1 to 10 days. PATIENTS AND SAMPLES: We evaluated the PCR technique on 64 stool samples obtained from patients with acquired immunodeficiency syndrome who had persistent chronic diarrhea. Patients were from Spain, Brazil, Germany, and the United States. RESULTS: Using this approach, we could confirm the presence of E bieneusi in all 17 positive samples; no false-positive results were observed. We could also amplify E bieneusi DNA in 10 aliquots of one sample fixed up to 10 days in 10% formalin. CONCLUSION: We conclude that PCR technology is very suitable for species identification of microsporidia in stool samples and may have a potential application in prospective studies in formalin-fixed samples.
