Project description:BACKGROUND:Portopulmonary hypertension (PoPH) is not uncommon in patients waiting for liver transplantation (LT). Severe PoPH has a very high perioperative mortality rate and is still considered a contraindication for LT. Many patients with liver disease require but cannot receive LT due to severe PoPH and eventually died. We report a patient with severe PoPH who underwent successful LT and had near normal pulmonary pressure without drug treatment. CASE SUMMARY:A 39-year-old woman was hospitalized with the chief complaint of jaundice and exertional dyspnea and fatigue. Caroli disease and liver cirrhosis was diagnosed 6 years previously. Her liver disease met the criteria for LT. However, right heart catheterization showed that her mean pulmonary artery pressure was increased at 50 mmHg, pulmonary vascular resistance was 460 dyn?s/cm5 and pulmonary artery wedge pressure was 20 mmHg, which may have been the reasons for her chief complaint. The patient was diagnosed with severe PoPH and was not listed for LT immediately. After 5 mo of pharmacotherapy, her severe PoPH was moderate, and she underwent successful LT. Pulmonary artery pressure steadily decreased according to post-operative echocardiographic monitoring and drugs have been discontinued for a month. CONCLUSION:The safety of LT can be greatly improved by reducing mean pulmonary artery pressure to a low level, and LT may cure PoPH.

Project description:BackgroundPrimary hyperoxaluria (PH) is a rare inherited autosomal recessive disease caused by disturbed glyoxylate metabolism. The disease is characterized by calcium oxalate crystal deposition in various organs, especially in the kidney. Due to the lack of current understanding of PH, nearly all patients are only initially diagnosed with PH when recurrent lithiasis and progressive end-stage renal disease occur. Many cases are not diagnosed in patients until renal allograft insufficiency occurs after renal transplantation. This case report and literature review aim to emphasize the need for careful pre-transplant PH screening of patients with bilateral nephrocalcinosis or nephrolithiasis.Case presentationRenal allograft insufficiency was diagnosed as PH after kidney transplantation. Here, we detail the complete clinical course, including computed tomography images of the original kidney and renal graft, histopathological images of a biopsy of the transplanted kidney, the results of laboratory and molecular genetic tests, and the treatment. In addition, we reviewed the literature from 2000 to 2021 and analyzed 19 reported cases of PH diagnosed after kidney transplantation, and provide a summary of the characteristics, complications, treatment, and prognosis of these cases.ConclusionsBy reviewing and analyzing these cases, we concluded that patients with a history of nephrocalcinosis or nephrolithiasis in both kidneys need preoperative screening for PH and appropriate treatment before kidney transplantation. Delayed graft function caused by PH is easily misdiagnosed as acute rejection, and needle biopsy should be performed at an early stage.

Project description:Homozygous familial hypercholesterolemia (HoFH) is a rare inherited metabolic disorder, frequently leading to an early cardiovascular death if not adequately treated. Since standard medications usually fail to reduce LDL-cholesterol (LDL-C) levels satisfactorily, LDL-apheresis is a mainstay of managing HoFH patients but, at the same time, very burdensome and suboptimally effective. Liver transplantation (LT) has been previously shown to be a promising alternative. We report on a 14 year-long follow-up after LT in a HoFH patient. At the age of 4, the patient was referred to our institution because of the gradually increasing number of xanthomas on the knees, elbows, buttocks, and later the homozygous mutation c.1754T>C (p.Ile585Thr) on the LDL-receptor gene was confirmed. Despite subsequent intensive treatment with the combination of diet, statins, bile acid sequestrant, probucol, and LDL-apheresis, the patient developed valvular aortic stenosis and aortic regurgitation by 12 years. At 16 years, the patient successfully underwent deceased-donor orthotopic LT. Nine years post-LT, we found total regression of the cutaneous xanthomas and atherosclerotic plaques and with normal endothelial function. Fourteen years post-LT, his clinical condition remained stable, but LDL-C levels have progressively risen. In addition, a systematic review of the literature and guidelines on the LT for HoFH patients was performed. Six of the 17 identified guidelines did not take LT as a treatment option in consideration at all. But still the majority of guidelines suggest LT as an exceptional therapeutic option or as the last resort option when all the other treatment options are inadequate or not tolerated. Most of the observed patients had some kind of cardiovascular disease before the LT. In 76% of LT, the cardiovascular burden did not progress after LT. According to our experience and in several other reported cases, the LDL-C levels are slowly increasing over time post LT. Most of the follow-up data were short termed; only a few case reports have followed patients for 10 or more years after LT. LT is a feasible therapeutic option for HoFH patients, reversing atherosclerotic changes uncontrollable by conservative therapy, thus importantly improving the HoFH patient's prognosis and quality of life.

Project description:Chronic myeloid leukemia (CML), a clonal myeloproliferative disorder of pluripotent hematopoietic stem cells, results from the Philadelphia chromosome (Ph) chromosome. The Ph is from a translocation, t(9;22)(q34q11), that creates a BCR-ABL fusion gene, which is transcribed into proteins with abnormal tyrosine kinase activity, driving the abnormal proliferation of white blood cells. Multiple myeloma (MM) is a proliferation disorder of plasma cells derived from a single clone, which may lead to uncontrolled growth, kidney injury, destructive bone lesions, hypercalcemia and anemia. It is extremely rare that MM and CML should occur in the same patient either synchronously or metachronously. To date, MM accompanied with CML has only been reported in limited studies, and the the cause behind the occurrence of both malignancies together is not understood. With the advent of novel therapies, the survival time in patients with CML and MM has improved. Therefore, the further investigation of the pathophysiology and clinical characteristics of these cases is valuable. The present study reports the case of a 79-year-old male who had been diagnosed with CML and treated with tyrosine kinase inhibitor, and then developed immunoglobulin G-κ MM after 6 years. This report should provide valid raw data for clinical research.

Project description:Atypical chronic myeloid leukemia (aCML), BCR-ABL1 negative is a rare myelodysplastic syndrome/myeloproliferative neoplasm for which no current standard of care exists. The blood smear of patients with aCML showed prominent immature granulocytosis, and granulocytic dysplasia. We admitted a 58-year-old man with splenomegaly, hyperleukocytosis, anemia, and thrombocytopenia; then cytology, cytogenetic and molecular biology analysis of bone morrow were performed and the diagnosis of aCML was made according to 2016 World Health Organization diagnostic criteria. The patient was initially treated by chemotherapy; the patient achieved an aggravation of anemia. This motivated the change of treatment.

Project description:Mevalonic aciduria (MA) is the most severe clinical subtype of mevalonate kinase deficiency (MKD) caused by an inherited defect in the mevalonate pathway. The treatment of MKD focuses on the suppression of recurrent hyperinflammatory attacks using anti-inflammatory drugs. Recently, allogeneic hematopoietic stem cell transplantation (HCT) was shown to successfully ameliorate autoinflammatory attacks in patients with MKD. Here, we report a case of an infant who showed severe recurrent systemic inflammation and was diagnosed with MA. Although she responded to steroids, her symptoms relapsed after the dose was tapered, and organ deterioration occurred. Therefore, at the age of 11 months, HCT from a matched, unrelated donor was performed for curative treatment. However, at 50 days after transplantation, acute myeloid leukemia was diagnosed, which was chemo-refractory. A second HCT from her haploidentical father was performed to treat the acute myeloid leukemia, but the patient died of sepsis on day 4 after transplantation. This is the first report of malignancy following HCT for MA. Our findings suggest that normalizing the mevalonate pathway after HCT in patients with MKD impacts patients differently depending on the clinical spectrum and severity of disease.

Project description:A primary liver perivascular epithelioid cell tumor (PEComa) is an extremely rare entity. In this article, we present a case report with a review of the literature on the patients diagnosed with primary liver PEComa and an elaboration of diagnostic and treatment modalities. A systematic literature search was conducted using the terms "perivascular epithelioid cell tumor", "PEComa", "liver", and "hepatic". All articles describing patients diagnosed with primary liver PEComa were included. We identified a total of 224 patients of primary liver PEComa from 75 articles and a case from the present study with a significant preponderance of females (ratio 4:1) and with a mean age of 45.3 ± 12.1 years. Most of the patients (114 out of 224, 50.9%) were asymptomatic. A total of 183 (81.3%) patients underwent surgical hepatic resection at the time of diagnosis, while 19 (8.4%) underwent surveillance. Recurrence and metastases were detected in seven (3.1%) and six (2.7%) patients, respectively. In conclusion, surgical resection remains the cornerstone of therapy; however, the presence of nonspecific imaging features makes it difficult to reach a definite diagnosis preoperatively. Therefore, a multidisciplinary approach should be the gold standard in selecting the treatment modality.

Project description:Background Epstein Barr virus-associated smooth muscle tumors (EBV-SMT) are rare neoplasms that can occur in immunocompromised individuals. The native or transplanted liver is the most commonly involved site in post transplant patients. Systemic therapies have been utilized in EBV-SMT with modest activity. Case Description We describe a 23-year-old female kidney transplant recipient who presented with acute myeloid leukemia (AML) and hepatic myeloid sarcoma (MS). Although it was not recognized initially, her liver biopsy revealing MS at diagnosis was posthumously found to have synchronous EBV-SMT. She underwent anthracycline based induction and achieved a complete remission of her AML by bone marrow biopsy. Due to a persistent hepatic mass, she was given salvage chemotherapy including fludarabine, etoposide, cytarabine, decitabine, and venetoclax for presumed refractory MS. Re-biopsy of the liver revealed the absence of MS and presence of EBV-SMT, which subsequently grew rapidly and precluded her from a liver tumor resection. The patient underwent sirolimus mammalian target of rapamycin (mTOR) therapy with palliative intent, but the patient’s EBV-SMT progressed shortly after. At time of autopsy, the patient remained in complete remission from AML/MS, but was found to have multifocal progressive metastatic EBV-SMT. Conclusions To our knowledge this is the first reported case of synchronous AML/MS and post transplant hepatic EBV-SMT that underwent treatment for AML/MS. Our report suggests that the chemotherapeutic agents utilized for AML/MS may have poor efficacy against EBV-SMT.

Project description:PurposeThis work reports a rare case of spontaneous suprachoroidal hemorrhage (SSCH) and summarizes the literature on its treatment options and outcomes.MethodsA case report and comprehensive literature review are presented on the medical and surgical management of SSCH on PubMed from 1998 to 2021.ResultsThe literature search revealed 58 studies, 33 of which included 52 eyes of 47 patients. Surgical treatment typically consisted of choroidal drainage with posterior sclerotomies combined with pars plana vitrectomy and silicone oil placement. Medical therapy involved intraocular pressure control with laser peripheral iridotomy and topical, oral, and intravenous medication.ConclusionsIn cases of SSCH, conservative management and a prompt workup should be initiated to identify the cause before proceeding with surgery. If the initial workup does not reveal a cause, medical and surgical treatments are both viable and the decision is at the discretion of the treating physician.

Project description:UnlabelledPerivascular epithelioid cell tumors (PEComas) encompass a group of rare mesenchymal neoplasms, which typically have a perivascular location with dual melanocytic and muscular differentiation. They are found in a variety of localizations, though lesions in the liver are exceedingly rare. Because of their rarity, the clinical, radiological and histological features of these tumors have yet to be established. This is why, it seems appropriate to report the observation of this rare hepatic tumor with a literary review including others published cases, assessing through it, clinicopathologic and radiologic features of all reported cases as well as their follow-up whenever possible.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1967094999126169.
