Hepatitis C virus-associated cryoglobulinemia with membrano-proliferative glomerulonephritis treated with prednisolone and interferon: A case report.

ABSTRACT: Hepatitis C virus (HCV) is a major cause of liver-associated morbidity and has an increasing prevalence worldwide. Hepatitis C virus infection may lead to chronic hepatitis, cirrhosis and liver failure. However, it is also associated with a wide range of extra-hepatic complications, such as cryoglobulinemia, an immune complex disease associated with cryoglobulin leading to multiple organ damage and, while the major symptom is vasculitis. The present study reported on a-58-year-old woman who was diagnosed with HCV-associated cryoglobulinemia with skin, kidney and blood system damage and biopsy-proven cryoglobulinemia membrano-proliferative glomerulonephritis. HCV RNA clearance occurred within a few weeks of interferon treatment and the patient was then treated by prednisolone and sustained interferon. While the therapeutic effect was obvious at first, the disease reappeared in combination with refractory infection and multiple organ failure, and the patient finally died. HCV-associated cryoglobulinemia is uncommon in developing countries such as China, while treatment guidelines remain to be established, particularly if complex complications are present.

A case of proliferative glomerulonephritis with immunoglobulin A1-lambda deposits successfully treated by chemotherapy.

Project description:A 74-year-old man presented with nephrotic syndrome and kidney insufficiency. Laboratory tests revealed monoclonal gammopathy of immunoglobulin A-lambda. Renal biopsy revealed diffuse mesangial proliferation and double-contoured basement membranes. Immunofluorescent analyses showed granular deposition of immunoglobulin A and C3 at the capillary walls and mesangial regions. Immunohistochemistry suggested monoclonal deposition of immunoglobulin A1-lambda. Electron microscopic analyses showed finely granular electron-dense deposits at mesangial and subendothelial areas. These findings suggested immunoglobulin A-type proliferative glomerulonephritis with monoclonal immunoglobulin deposits. Based on the results of bone marrow aspiration, multiple myeloma was diagnosed. Because the renal manifestation was considered to be affected by monoclonal gammopathy, chemotherapy was initiated rather than immunomodulatory therapy. Although bortezomib and dexamethasone proved ineffective, second chemotherapy with elotuzumab, lenalidomide, and dexamethasone was successful, and kidney function recovered. Effective treatments for proliferative glomerulonephritis with monoclonal immunoglobulin deposits have not been established. This represents the first description of a patient successfully treated for proliferative glomerulonephritis with monoclonal immunoglobulin deposits by chemotherapy using elotuzumab.

Efficacy of belimumab for severe childhood-onset systemic lupus erythematosus with diffuse proliferative glomerulonephritis: A case report.

Project description:IntroductionTherapy of childhood-onset systemic lupus erythematosus (cSLE) with drugs is unsatisfactory. Some new drugs such as belimumab and rituximab may improve the course of severe cSLE, although there are few reports on treatment efficiency for these new drugs, especially belimumab.Case presentationHere we report on a 16-year-old girl who was diagnosed with cSLE at the age of 13. After several immunosuppressive treatments, which included high-dose steroids, hydroxychloroquine sulfate, cyclophosphamide, etc for blood system damage, she showed little clinical improvement and developed severe pericarditis. Induction treatment with a combination of intravenous high-dose steroids, methylprednisolone, and cyclophosphamide was started, but, after 55 days, the patient developed lupus encephalopathy, lung infection, and lupus nephritis. After using high-dose steroids, cyclophosphamide, plasma exchange, gamma globulin, and appropriate anti-pulmonary inflammation drugs, treatment with tacrolimus was attempted but poorly tolerated by the patient and withdrawn. Eventually, in December 2019, belimumab was initiated on an off-label basis as a last resource to treat lupus nephritis. Belimumab was well tolerated by the patient and resulted in a rapid and marked improvement in clinical symptoms and reduction in proteinuria, serum complement levels and anti-double strand DNA antibodies titer; of note, the patient developed no infectious complications.ConclusionTreatment with belimumab could result in prompt remission of severe cSLE with multiple organ damage without the pulmonary infection side effects for children deemed intolerant to conventional and second-line induction therapies. Belimumab should be considered as a potentially efficacious treatment in patients in severe childhood-onset systemic lupus erythematosus.

Case report: membranoproliferative glomerulonephritis associated with Q fever causing chronic endocarditis.

Project description:BackgroundMembranoproliferative glomerulonephritis is a rare entity which can be a result from autoimmune diseases, caused by various medications and infections.Case presentationWe herein present the case of a 62-year-old male patient who presented with fatigue and was found to have severe anemia, impaired renal function, and nephrotic syndrome. A renal biopsy revealed membranoproliferative glomerulonephritis (MPGN) of the immune complex type with activation of the classical complement pathway. Further investigations led to the diagnosis of a chronic Coxiella burnetii-infection (Q fever), likely acquired during cycling trips in a region known for intensive sheep farming. Additionally, the patient was found to have a post endocarditic destructive bicuspid aortic valve caused by this pathogen. Treatment with hydroxychloroquine and doxycycline was administered for a duration of 24 months. The aortic valve was replaced successfully and the patient recovered completely.ConclusionsEarly detection and targeted treatment of this life-threatening disease is crucial for complete recovery of the patient.

Case Report Associated with Aspergillosis and Hepatitis E Virus Coinfection in Himalayan Griffons.

Project description:This study involved a death which occurred in four Himalayan griffons housed in Beijing zoo, China. Based on pathogen identification and the pathological changes observed, we did characterize the fungi and Hepatitis E virus (HEV) in four dead Himalayan griffons. Pathological changes were severe. Membranous-like material was observed on the surface of the internal organs. Spleen was necrotic. Focal lymphocyte infiltration in the liver and many sunflower-like fungi nodules were evident in the tissues, especially in the kidney. PCR was used to identify the pathogen. Based on the 18SrRNA genomic sequence of known fungi, the results confirmed that all four dead Himalayan griffons were infected with Aspergillus. At the same time the detection of HEV also showed positive results. To the best of our knowledge, this work appears to be the first report of concurrent presence of Aspergillosis and Hepatitis E virus in rare avian species.

Exacerbation of hepatitis C induced subclinical hypoadrenalism by Interferon-alpha2beta: A case report.

Project description:Adrenal disease is an uncommon manifestation of hepatitis C infection and its related treatment regimen. This is a case of subclinical hypoadrenalism, probably induced by hepatitis C infection and further exacerbated by interferon-alpha2beta and Ribavirin therapy. The adrenal deterioration during the treatment course was observed closely with 24-hour salivary profiles and 250 mug adrenocorticotropin stimulation tests using parallel serum and salivary cortisol concentrations. A number of possible pathogenic mechanisms are discussed, and the controversy over its management is emphasized.

A Rare Case of Adult Autoimmune Neutropenia Successfully Treated with Prednisolone.

Project description:Autoimmune neutropenia (AIN) is a rare disorder that may cause life-threatening infections. In adults, most cases are secondary to other pathological conditions, and primary AIN is extremely rare. We herein report a case involving a 57-year-old woman diagnosed with AIN. A granulocyte immunofluorescence test detected autoantibodies against human neutrophil antigens in her serum, while various examinations revealed no other causes of neutropenia, suggesting her AIN was primary. She was refractory to granulocyte-colony-stimulating factor but responded to prednisolone. Her neutrophil count remained normal after gradual discontinuation of prednisolone. Diagnostic procedures and optimal treatments for this disorder need to be established.

A case of papilledema in Camurati-Engelmann disease treated effectively with prednisolone.

Project description:Camurati-Engelmann disease (CED) causes bone pain, muscle weakness, and cranial nerve symptoms due to abnormal thickening of the long bones of the limbs and the cortex of the skull. The pathophysiology of CED is a gain-of-function variant of transforming growth factor beta 1 (TGFB1). The ophthalmological symptoms of CED are usually caused by increased intracranial pressure and optic canal stenosis. Here, we report the case of a patient in whom prednisolone was effective against papilledema caused by CED. In this case, when papilledema was observed in both fundi, the patient showed increased bone pain, fever, and elevated CRP and ALP levels. Brain magnetic resonance imaging (MRI) revealed a high short tau inversion recovery (STIR) signal in both optic nerves, suggesting edematous changes. Prednisolone ameliorated bone pain, fever, and papilledema, resulting in a slight improvement of the visual function of the right eye. Our results suggest that prednisolone may be effective in treating ophthalmologic symptoms in addition to bone pain in patients with CED.

Role of fluid-phase complement system regulation in the development of hepatitis C virus-associated glomerulonephritis.

Project description:ObjectivesIt is not known why only some hepatitis C virus (HCV) infected patients develop glomerulonephritis (GN). Therefore, we investigated the role of soluble complement regulators in the development of HCV associated GN.MethodsPatients with HCV associated GN who were admitted to our nephrology unit between July 2016 and July 2018 were recruited to the study (group 1). Two other age and sex matched groups were studied as control groups: patients with HCV without GN (group 2) and healthy HCV negative volunteers (group 3). There were 26 participants in each of the three groups at the end of the recruitment period. An assay of serum fluid-phase complement regulators was performed using enzyme linked immunosorbent assay technique. Three complement single nucleotide polymorphisms (SNPs) were analyzed using real time polymerase chain reaction (Taqman; thermo fisher scientific): rs2230199 and rs1047286 for complement 3 (C3) and rs800292 for complement factor H (CFH).ResultsSerum levels of complement 4 binding protein (C4BP) were significantly lower in group 1 (median 70 ng/ml) than in groups 2 (median 88.8 ng/ml) and 3 (median 82.8 ng/ml) with p value of 0.007. The minor allele (allele A) of rs800292 for CFH was significantly higher in group 2 and group 3 (G 54% and A 46%) than in group 1 (G 73% and A 27%), p = 0.04.ConclusionsLow C4BP levels are associated with GN in HCV infected patients. In addition, rs800292 SNP in CFH protects against GN in patients with HCV.

Efficacy and safety of anti-viral therapy for Hepatitis B virus-associated glomerulonephritis: A meta-analysis.

Project description:OBJECTIVES:To assess the potency of anti-viral treatment for hepatitis B virus-associated glomerulonephritis (HBV-GN). Method: We searched for controlled clinical trials on anti-viral therapy for HBV-GN in MEDLINE, Embase, the Cochrane Library, and PubMed from inception to March 11th 2019. Seven trials, including 182 patients met the criteria for evaluating. The primary outcome measures were proteinuria and changes in the estimated glomerular filtration rate, and the secondary outcome measure was hepatitis B e-antigen clearance. A fixed or random effect model was established to analyze the data. Subgroup analyses were performed to explore the effects of clinical trial type, anti-viral drug type, age, and follow-up duration. RESULTS:The total remission rate of proteinuria (OR = 10.48, 95% CI: 4.60-23.89, I2 = 0%), complete remission rate of proteinuria (OR = 11.64, 95% CI: 5.17-26.21, I2 = 23%) and clearance rate of Hepatitis Be Antigen (HBeAg) were significantly higher in the anti-viral treatment group than in the control group (OR = 27.08, 95% CI: 3.71-197.88, I2 = 63%). However, antiviral therapy was not as effective regarding the eGFR (MD = 5.74, 95% CI: -4.24-15.73). In the subgroup analysis, age and drug type had significant impacts on proteinuria remission, and study type and follow-up duration only slightly affected the heterogeneity. CONCLUSION:Antiviral therapy induced remission of proteinuria and increased HBeAg clearance but failed to improve the eGFR. Pediatric patients were more sensitive to antiviral therapy than adults. IFNs seem more effective but are accompanied by more adverse reactions than NAs.
