ABSTRACT
OBJECTIVE: This study aimed to identify factors associated with refractory severe hypertension that does not resolve after an initial dose of antihypertensive medication in patients with preeclampsia. STUDY DESIGN: This was a retrospective study of all pregnant and postpartum individuals with a diagnosis of preeclampsia, superimposed preeclampsia, HELLP (hemolysis, elevated liver enzymes, low platelet) syndrome, or eclampsia who delivered at 22 weeks or greater at a single academic institution from 2010 to 2020. Inclusion criteria were patients with preeclampsia who developed severe hypertension (systolic pressure ≥160 mm Hg or diastolic pressure ≥110 mm Hg) and received antihypertensive medications for acute severe hypertension. We defined refractory severe hypertension as a systolic blood pressure of ≥160 mm Hg or a diastolic blood pressure of ≥110 mm Hg that did not improve after receiving the initial treatment. To evaluate for factors associated with refractory severe hypertension, we developed multivariable modified Poisson regression using all variables with p-value <0.1 on bivariable analysis and calculated adjusted relative risks (aRRs) with 95% confidence intervals (95% CIs). RESULTS: Of 850, 386 (45.4%) had refractory severe hypertension and 464 (54.6%) responded to the initial antihypertensive medications. Factors associated with refractory severe hypertension included higher body mass index (BMI), chronic hypertension, and higher systolic pressure. Every 5 kg/m2 increase in BMI was associated with a 7% increased risk of refractory severe hypertension (aRR = 1.07; 95% CI: 1.02-1.12). Every 10 mm Hg increase in systolic blood pressure was associated with a 10% increased risk of refractory severe hypertension (aRR = 1.10; 95% CI: 1.04-1.17). Chronic hypertension was associated with a 25% increased risk of refractory severe hypertension (aRR = 1.25; 95% CI: 1.01-1.56) in the diastolic pressure model. CONCLUSION: Refractory severe hypertension was associated with elevated BMI, chronic hypertension, and higher systolic blood pressure. KEY POINTS: · Risk factors for refractory severe hypertension are not well-known.. · Almost half of the patients had refractory severe hypertension.. · Higher BMI, chronic hypertension, and higher systolic pressure were the risk factors.. · These patients would require closer follow-up and prompt response to vital signs..
ABSTRACT
POEMS syndrome, a rare plasma cell disorder, is challenging both in the diagnostic and therapeutic management. We present real word retrospective analysis of 108 cases analyzing clinical features and therapeutic modes. We compare our results with the available literature. This is the first description with such wide use of proteasome inhibitors in first line treatment. POEMS (Polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes) syndrome is a rare and challenging plasma cell disorder, both in the diagnostic and therapeutic management of the disease. Currently, the literature on POEMS is sparse with most evidence being case reports and small case studies. We present a retrospective real world experience of 108 patients with POEMS. We analyzed the clinical features and therapeutic interventions. Regarding clinical features, our findings demonstrated that skin lesions, thrombocythemia and polycythemia were present less frequently than reported previously. Regarding clinical interventions, this is one of the largest analyses of front line treatment in POEMS and the first one to include frequent utilization of proteasome inhibitors (37%). Bortezomib monotherapy was the most effective therapy achieving complete remission/very good partial remissions (CR/VGPR) in 69% of patients. Thirty percent of patients proceeded to planned autologous stem cell transplant (ASCT) as part of the front-line treatment resulting in statistically superior progression-free (PFS) and overall survival (OS) compared to non-ASCT treated patients (P= .003). In multivariate analysis, anemia, thrombocytopenia, and as age over 60 were associated with a negative impact on patient outcomes.

Combination treatment regimens including a proteasome inhibitor (PI), an immunomodulatory agent (IMiD) and a corticosteroid are standards of care for initial treatment of multiple myeloma (MM). We aimed to evaluate if a sequential treatment program using PI induction followed by IMiD based consolidation and maintenance could achieve similar outcomes with reduced toxicities. This phase 2 study was designed to assess the safety and efficacy of the Car-BiRd regimen: carfilzomib and dexamethasone (Kd) induction until maximum response, followed by lenalidomide, clarithromycin and dexamethasone (BiRd) consolidation until next maximum response, then lenalidomide maintenance in patients with newly diagnosed MM. Seventy-two patients, including both transplant eligible and ineligible patients, were enrolled and evaluated for response. The overall response rate to the Car-BiRd regimen was 94% with 83% of patients achieving a ≥ VGPR and 35% achieving a CR/sCR. The rate of CR/sCR increased from 7% with Kd induction to 21% with BiRd consolidation and 35% with lenalidomide maintenance. These results did not meet the study's target endpoint of a CR rate of 55%. The median PFS using this deferred transplant approach was 37.3 months (95% CI 27.9, 52.7) and median OS was not reached with a median follow-up of 60 months. Toxicities were primarily low grade and manageable. Hematologic toxicities were lower than those expected with a combination PI/IMiD protocol. The sequential Car-BiRd regimen is an effective and safe approach for the upfront treatment of MM including patients unfit for transplant.
