RESUMO
BACKGROUND: Patients with vasculitis, a set of rare diseases, encounter delays in obtaining an accurate diagnosis which can lead to substantial morbidity and increased mortality. This study sought to describe the diagnostic journey of patients with vasculitis and identify factors associated with time to diagnosis. METHODS: Patients with vasculitis enrolled in an online registry completed a two-stage study: Stage 1: survey of open-ended questions about patients' diagnostic journeys and perceived factors associated with rapid or delayed diagnosis; Stage 2: survey with specific questions based on data from Stage 1 and additional investigator-identified factors. RESULTS: 375 patients with vasculitis participated in Stage 1; 456 patients participated in Stage 2. 85% of patients were seen by a healthcare provider within 3 months of the onset of symptoms. The median time to diagnosis of vasculitis was 7 months. 313/456 (73%) of patients were misdiagnosed initially. 40% of diagnoses were made in a hospital setting; 2% of diagnoses were made at a specialized vasculitis center. 60% of patients had at least 1 visit to an emergency room prior to diagnosis. Unemployment, time to travel to a medical center > 1 h, initial misdiagnosis, and delays in seeing a specialist were all associated with longer times to diagnosis. 373/456 (82%) of patients reported that a delayed diagnosis had negative consequences on their health. CONCLUSION: Patients with vasculitis encounter substantial delays in achieving an accurate diagnosis and these delays are associated with negative health consequences. Both patient-related factors and healthcare-related factors are associated with diagnostic delays.

The interpretation of positive serologic findings in cancer sera remains controversial. Selected antinuclear antibodies (ANAs), such as anti-double-stranded deoxyribonucleic acid (dsDNA) and anti-Smith, are highly specific for the diagnosis of systemic lupus erythematosus (SLE). On the other hand, the ANA titer is sensitive but not specific for SLE and has been reported in healthy individuals, various infections, other autoimmune diseases and cancer. We report for the first time positive anti-Smith antibody in two patients without lupus in the setting of lung cancer.
RESUMO
Glomerulonephritis (GN) in lupus is generally an immune complex glomerulonephritis from the deposition of immunoglobulin and complements. Pauci-immune GN is the most common cause of rapidly progressive GN and is frequently associated with an anti-nuclear cytoplasmic antibody (ANCA). We report a patient with a history of systemic lupus erythematosus who presented with worsening proteinuria and was subsequently diagnosed with pauci-immune GN on renal biopsy, in the absence of ANCA.

RESUMO
Variability in systemic lupus erythematosus (SLE) disease manifestations is well recognized. Lupus disease activity can range from mild to severe. Fever is a common manifestation of SLE and occurs in 36%-86% of patients. In the Modified Systemic Lupus Erythematosus Disease Activity Index (M-SLEDAI), fever is taken into account as disease activity scoring. Assessment of lupus patients with fever is an important diagnostic challenge, since the initial clinical presentation of a patient with lupus is very similar to the acute febrile phase of an infection. The attribution of fever to SLE holds only after other causes are excluded.
RESUMO
Pulmonary hypertension (PH) is a life-threatening complication of several, different connective tissue diseases, including systemic lupus erythematous (SLE), systemic sclerosis, and rheumatoid arthritis. PH can present early in SLE. The severity does not correlate with other organ disease activity or with disease duration. It is still debatable whether immunosuppressive therapy is useful for PH related to SLE or autoimmune connective tissue disease, as there are no large clinical trials. However, several case reports have shown improvement with cyclophosphamide and prednisone with or without vasodilator therapy. We present a case of SLE-related PH in which a dramatic improvement in mean pulmonary artery pressure and exercise capacity was noted after the institution of treatment with mycophenolate mofetil, resulting in a decrease in corticosteroid dose. Our observations support the potential value of mycophenolate mofetil therapy for PH in SLE.
RESUMO
OBJECTIVE: To determine perceived barriers and facilitators to effective mentoring for early career rheumatology investigators and to develop a framework for an inter-institutional mentoring program. METHODS: Focus groups or interviews with rheumatology fellows, junior faculty, and mentors were conducted, audiorecorded, and transcribed. Content analysis was performed using NVivo software. Themes were grouped into categories (e.g., mentor-mentee relationship, barriers, and facilitators of a productive relationship). Rheumatology fellows and early career investigators were also surveyed nationwide to identify specific needs to be addressed through an inter-institutional mentoring program. RESULTS: Twenty-five individuals participated in focus groups or interviews. Attributes of the ideal mentee-mentor relationship included communication, accessibility, regular meetings, shared interests, aligned goals, and mutual respect. The mentee should be proactive, efficient, engaged, committed, focused, accountable, and respectful of the mentor's time. The mentor should support/promote the mentee, shape the mentee's goals and career plan, address day-to-day questions, provide critical feedback, be available, and have team leadership skills. Barriers included difficulty with career path navigation, gaining independence, internal competition, authorship, time demands, funding, and work-life balance. Facilitators of a successful relationship included having a diverse network of mentors filling different roles, mentor-mentee relationship management, and confidence. Among 187 survey respondents, the primary uses of an inter-institutional mentoring program were career development planning and oversight, goal-setting, and networking. CONCLUSIONS: In this mixed-methods study, tangible factors for optimizing the mentor-mentee relationship were identified and will inform the development of an adult rheumatology inter-institutional mentoring program.

Haptoglobin levels are measured in systematic lupus erythematosus patients as part of the workup for anemia, with low levels indicating hemolysis. Haptoglobin is an acute phase protein. We present 2 lupus patients who were found to have low haptoglobin levels in the absence of other evidence of hemolysis.
