ABSTRACT

Hepatic infarction is uncommon due to the dual blood supply from the hepatic artery and portal vein. The majority of the cases are caused following liver transplant or hepatobiliary surgery, hepatic artery occlusion, or shock. Hepatic infarction is a rare complication of hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. HELLP is an obstetrical emergency requiring prompt delivery. The presence of elevated liver enzymes, mainly alanine aminotransferase and aspartate aminotransferase in pre-eclampsia, should warrant diagnosis and treatment in the line of HELLP syndrome. Our patient with underlying sickle cell trait presented with features of HELLP syndrome in her third trimester of pregnancy. She underwent cesarean delivery on the same day of the presentation. The liver enzymes continued to rise following delivery and peaked on postoperative day two. Contrast computed tomography scan showed multifocal hepatic infarctions. Pre-eclampsia by itself is a state of impaired oxygenation and can lead to hepatic hypoperfusion, and appeared to be a clear contributor to the hepatic infarction in this case. However, this case also raises the question of whether the underlying sickle cell trait might have potentiated the hepatic infarction. Although sickle cell disease is well known to cause hepatic infarctions, it is unknown whether the sickle cell trait affects the liver to a similar extent as sickle cell disease. In addition, there have been case reports of sickle cell trait causing splenic infarcts and renal papillary necrosis, but it remains unclear if it can be directly associated with hepatic infarction.

ABSTRACT

We present a case of rapidly progressive granulomatous amoebic encephalitis caused by Balamuthia mandrillaris in an individual with diabetes mellitus. Our patient presented with occipital headache, blurry vision, confusion, and gait imbalance of one week's duration. Brain imaging revealed numerous peripheral ring-enhancing lesions concerning malignancy. Brain biopsy was consistent with Balamuthia mandrillaris infection. He passed away 45 days after presentation despite being treated with a five-drug regimen. This case highlights the importance of considering amoebic brain infections, especially with ring-enhancing lesions on imaging. There are opportunities to design modalities for rapid diagnosis and better treatment.

ABSTRACT

BACKGROUND: Heart failure (HF) with preserved ejection fraction (HFpEF) causes significant cardiovascular morbidity and mortality. It is a growing problem in the developed world, especially, in the aging population. There is a paucity of data on the treatment of patients with HFpEF. We aimed to identify pharmacotherapies that improve peak oxygen consumption (peak VO2), cardiovascular mortality, and HF hospitalizations in patients with HFpEF. METHODS: We conducted a systematic literature search for English studies in PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, Scopus, and Google scholar. We searched databases using terms relating to or describing HFpEF, stage C HFpEF, and diastolic HF and included only randomized controlled trials (RCTs). RevMan 5.4 (The Cochrane Collaboration, 2020, London, UK) was used for data analysis, and two independent investigators performed literature retrieval and data-extraction. We used PRISMA guidelines to report the outcomes. We included 14 articles in our systematic review and six studies in meta-analysis. RESULTS: We calculated the pooled mean difference (MD) of peak VO2 between placebo and pharmacotherapies. Our meta-analysis showed that the peak VO2 was comparable between pharmacotherapies and placebo in HFpEF (MD = 0.09, 95% CI: -0.11, 0.30, I2 =28%). Our systematic review highlights that statins and spironolactone use should be further studied in larger RCTs due to their potential beneficial effect on all-cause mortality and hospitalizations, respectively. CONCLUSION: Compared to placebo, none of the pharmacotherapies significantly improved peak VO2 in HFpEF except ivabradine. In our meta-analysis, the pooled improvement in peak VO2 is non-significant. This needs validation with larger studies. We are lacking larger studies on pharmacotherapies that improve peak VO2 in HFpEF. Statin and spironolactone should be further studied in patients with HFpEF as few trials have shown improvement in all-cause mortality and reduction in HF hospitalizations in selected patients, respectively.
