ABSTRACT
BACKGROUND: Literature on bioresorbable-polymer-stents (BPS) and second-generation durable-polymer-stents (DPS) in percutaneous coronary intervention (PCI) for all comer CAD is conflicting. METHODS: Randomized controlled studies comparing PCI among BPS and second-generation DPS were identified up until May-2020 from online databases. Primary outcomes included are all-cause myocardial infarction (MI), cardiac-death, target-vessel-revascularization (TVR), target-vessel MI (TVMI), and stent-thrombosis (ST). Random effect method of risk ratio and confidence interval of 95% was used. RESULTS: 25 prospective randomized controlled trials with 31,822 patients (BPS n = 17,065 and DPS n = 14,757) were included in the study. Follow-up ranged between a minimum of 6 months to more than 5 years. Cardiac death (RR 1.02, 95% CI 0.89-1.45, p = 0.16) was comparable in BPS and second-generation DPS. Risk of all-cause MI was similar between BPS and DPS (RR 0.97, 95% CI 0.84-1.11, p = 0.73). TVMI (RR 0.88, 95% CI 0.69-1.11, p = 0.33) and ST rates were also comparable in BPS and DPS groups (RR 1.06, 95% CI 0.80-1.40, p = 1.00). Overall TVR had comparable outcomes between BPS and DPS (RR 0.95, 95% CI 0.79-1.14, p < 0.001); however, higher TVR was seen among BPS group at follow-up of ≥5 years (RR 1.39, 95% CI 1.12-1.14, p = 0.02). Bias was low and heterogeneity was moderate. CONCLUSION: Patients undergoing PCI treated with BPS had comparable outcomes in terms of cardiac death, TVR, ST, TVMI, and all-cause MI to patients treated with second-generation DPS; however, BPS had higher rates of TVR for follow-up of ≥5-years.

Multiple myeloma affects upwards of 30,000 people every year and has significant morbidity and mortality. Common complications of the disease involve lytic bone lesions, hypercalcemia, anemia, and acute renal failure. A rare, yet serious, complication includes acute liver failure secondary to hepatic plasma cell infiltration. While this is reported seldom in living patients, it is found in upwards of 40% of patients incidentally on imaging or during autopsy. Conscientious and meticulous monitoring of liver function tests allows for early detection of liver failure in multiple myeloma; thus, allowing for broader therapeutic options overall.
ABSTRACT
Haemophagocytic lymphohistiocytosis (HLH) is a potentially life-threatening syndrome caused by excessive immune activation. Secondary HLH has been described in autoimmune diseases. We detail the case of a 28-year-old African American woman who developed HLH in the setting of systemic lupus erythematosus with collapsing lupus podocytopathy superimposed on mesangial proliferative lupus nephritis class II. Genotyping for APOL1 risk alleles revealed the presence of double (G1/G2) risk alleles. Our patient achieved a complete renal recovery and resolution of HLH within 1 month of treatment with steroids and mycophenolate mofetil, highlighting the importance of prompt, aggressive therapy.
