Cytomegalovirus (CMV) infection and disease is a condition usually described in immunocompromised patients, but among them, those with connective tissue diseases are poorly represented. Here we present the clinical, laboratory characteristics, management and outcomes of systemic lupus erythematosus (SLE) patients who presented with a CMV infection/disease to a high complexity hospital in southwestern Colombia between 2011 and 2020. 16 SLE patients were found to have a CMV infection. SLE was predominantly characterized by renal involvement (10 patients; 62.50%), and 14 patients (87.5%) were receiving steroids previous to the CMV infection. The entire sample required hospital admission, mainly related to acute kidney injury, and nine patients were admitted to the intensive care unit (ICU). Gastrointestinal organ damage was the most common CMV disease manifestation. All patients received ganciclovir, five of them (31.25%) suffered from septic shock, and seven (43.75%) died. Age ≥38 years and the presence of septic shock at admission were correlated to the mortality outcome. To our knowledge, this is the first publication evaluating SLE patients with CMV infection/disease in a Colombian population., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Pregnant women with SLE have higher probabilities of maternal complications. SLE during pregnancy has alternating patterns of remission and flare-ups; however, most pregnant SLE patients tend to worsen with associated poor obstetric and perinatal outcomes. This study aimed to describe obstetric outcomes in pregnant women with SLE., Methods: This retrospective study was performed between 2011 and 2020 at a highly complex referral health center in Cali, Colombia. Pregnant women with a diagnosis of SLE were included. Demographic, clinical, and laboratory features and obstetric and fetal outcomes, including intensive care unit (ICU) characteristics, were evaluated., Results: Forty-eight pregnant women with SLE were included. The median age was 29 (25-33.7) years. The SLE diagnosis was made before pregnancy in 38 (79.1%) patients, with a median disease duration of 46 (12-84) months. Thirteen (27.1%) patients had lupus nephritis. Preterm labor (34, 70.8%), preeclampsia (25, 52%), and preterm rupture of membranes (10, 20.8%) were the most common obstetric complications. A relationship between a greater systemic lupus erythematosus pregnancy disease activity index (SLEPDAI) and the development of hypertensive disorders during pregnancy was established (preeclampsia = p < 0.0366; eclampsia = p < 0.0153). A relationship was identified between lupus nephritis (LN) and eclampsia ( p < 0.01), preterm labor ( p < 0.045), and placental abruption ( p < 0.01). Seventeen (35.4%) patients required ICU admission; 52.9% of them were due to AID activity, 17.6% for cardiovascular damage, 11.7% for septic shock, and 5.8% for acute kidney failure. Fetal survival was 89.5% ( N = 43/48). Among the live births, two (4.2%) newborns were diagnosed with neonatal lupus, and two (4.2%) were diagnosed with congenital heart block. One maternal death was registered due to preeclampsia and intraventricular hemorrhage., Conclusions: This study is the first to describe SLE during pregnancy in Colombia. SLE was the most prevalent AID in this cohort, and complications included preterm labor, preeclampsia, and postpartum hemorrhage. A higher SLEPDAI and lupus nephritis predicted adverse maternal outcomes.

Background: Nontraumatic acute transverse myelitis (ATM) can occur in response to infectious, inflammatory and vascular triggers; 1% of patients with systemic lupus erythematosus (SLE) develop ATM, but the mechanism remains unknown., Objective: The objective of this case report is to describe a case of intrathecal formation of anticardiolipin antibodies (aCL) during SLE-related ATM., Methods: A single patient analysis was conducted., Results: A 26-year-old housewife was diagnosed with SLE at age 19. Circulating aCL antibodies were positive at diagnosis. At age 21, she developed an episode of severe sepsis. At 23 years of age she developed an episode of ATM that left her paraplegic with a D10 sensory level, from which she recovered partially. Three years later, she developed a clinical relapse of ATM. During that second episode, serum levels of aCL were within normal limits, while cerebrospinal fluid levels were increased, suggesting intrathecal production of aCL., Conclusion: Here, we present a case of a woman who developed relapsing SLE-related longitudinally extensive ATM in whom intrathecal formation of aCL was demonstrated, suggesting that local production and cross-recognition of nervous tissue by those autoantibodies may be myelopathic.

Background and objective Acute transverse myelitis (TM) is an infrequent neurological complication of systemic lupus erythematosus (SLE). Short-term outcome varies widely between cohorts. Little is known about the epidemiology and long-term functional outcome of TM associated to SLE. Methods Patients with SLE and acute TM were identified during hospital admission, visits to the Emergency Room or the Neurology Outpatient Clinic. We evaluated ambispectively those patients with SLE presenting with clinical myelopathy and corroborated with spinal MRI. Cases were divided as partial (non-paralyzing) or complete (paralyzing). We determined long-term functional outcome as well as mortality in those patients with follow-up periods of at least five years. Results We identified 35 patients (partial, n = 15; complete, n = 20) in which complete clinical and imaging data were available (26 with follow-up ≥ 5 years). Patients with complete TM were significantly older than those with partial forms. Positive antiphospholipid antibodies were observed in 80% of patients, suggesting a possible mechanistical role. Surprisingly, functional recovery at one year was in general good; however, we observed a five-year mortality of 31% because of sepsis (in 10 cases) or pulmonary embolism (in one case). Conclusions Short-term outcome of SLE-related TM is generally good, and recurrence rate is low. However, we observed a long-term fatality rate of 31% for reasons unrelated to TM, suggesting that TM is a manifestation of severe immune dysregulation and a predictor of severity and mortality in patients with SLE.

Background/Objective Differentiating systemic lupus erythematosus (SLE) activity from infections in febrile patients is difficult because of similar initial clinical presentation. The aim of this study is to evaluate the usefulness of a number of biomarkers for differentiating infections from activity in SLE patients admitted with systemic inflammatory response (SIRS). Methods Patients with SLE and SIRS admitted to the emergency room were included in this study. Measurements of different markers including procalcitonin, neutrophil CD64 expression and presepsin, were performed. Infection was considered present when positive cultures and/or polymerase chain reaction were obtained. Sensitivity and specificity were calculated for all biomarkers. Results Twenty-seven patients were admitted, 23 women (82.5%), mean age 33.2 years. An infectious disease was confirmed in 12 cases. Markers for SLE activity including anti-DNA titers by IIF ( p = 0.041) and enzyme-linked immunosorbent assay ( p = 0.009) were used for differentiating SLE flares from infection. On the contrary, increased procalcitonin ( p = 0.047), neutrophil CD64 expression by flow cytometry ( p = 0.037) and presepsin ( p = 0.037) levels were observed in infected SLE patients. Conclusions High neutrophil CD64 expression, presepsin and procalcitonin levels are useful to differentiate infections from activity in SLE patients. In most cases, a positive bioscore that includes these three markers demonstrate the presence of an infectious disease.
