Recurrent leishmaniasis in kidney transplant recipients: Report of 2 cases and systematic review of the literature
2011
The characteristics of 8 episodes of leishmaniasis with atypical manifestations in 2 Italian kidney transplant recipients are analyzed and contextualized among those of 52 other episodes of leishmaniasis observed in 19 transplant recipients found through a systematic review of the international literature. In all the patients, the initial episode was visceral leishmaniasis, which was associated with mucocutaneous involvement in 2 cases. With the exception of 1 case of post kala-azar dermal leishmaniasis, 2 episodes of Leishmania endophthalmitis, and 3 episodes of mucocutaneous leishmaniasis, all the recurrences were characterized by visceral involvement. The potential role of polymerase cha…
Executive summary of the 2018 KDIGO Hepatitis C in CKD Guideline: welcoming advances in evaluation and management
2018
Infection with the hepatitis C virus (HCV) has adverse liver, kidney, and cardiovascular consequences in patients with chronic kidney disease (CKD), including those on dialysis therapy and in those with a kidney transplant. Since the publication of the original Kidney Disease: Improving Global Outcomes (KDIGO) HCV Guideline in 2008, major advances in HCV management, particularly with the advent of direct-acting antiviral therapies, have now made the cure of HCV possible in CKD patients. In addition, diagnostic techniques have evolved to enable the noninvasive diagnosis of liver fibrosis. Therefore, the Work Group undertook a comprehensive review and update of the KDIGO HCV in CKD Guideline.…
Clinical, immunological, and molecular analysis in a large cohort of patients with X-linked agammaglobulinemia: an Italian multicenter study
2002
A questionnaire-based retrospective clinical and immunological survey was conducted in 73 males with a definite diagnosis of X-linked agammaglobulinemia based on BTK sequence analysis. Forty-four were sporadic and 29 familial cases. At December 2000, the patients' ages ranged from 2 to 33 years; mean age at diagnosis and mean duration of follow-up were 3.5 and 10 years respectively. After the mid-1980s all but 2 were on intravenous immunoglobulin (IVIG) substitution therapy, with residual IgG >500 mg/dl in 94% of the patients at the time of enrollment. Respiratory infections were the most frequent manifestation both prior to diagnosis and over follow-up. Chronic lung disease (CLD) was prese…
Use of intravenous immunoglobulins in Lyell syndrome: Experience of three cases
1996
We present our experience of treatment of the last three cases of Lyell syndrome we have observed. They are three female children, aged between 16 months and 3 years, who showed many features in common with severely burnt patients (large exuding lesions, severe reduction of circulating plasmatic volume, large denuded body surfaces, severe tendency to infections, ...). Therefore, together with the already known scheme of treatment (corticosteroids, correction of hydroelectrolitic balance, antimicrobials), we decided to use intravenous Immunoglobulins (IVIG), which had been already positively used in severely burnt patients. The favorable evolution of the affection in all three cases and the …
Canakinumab for the Treatment of Autoinflammatory Recurrent Fever Syndromes.
2018
BACKGROUND: Familial Mediterranean fever, mevalonate kinase deficiency (also known as the hyperimmunoglobulinemia D syndrome), and the tumor necrosis factor receptor-associated periodic syndrome (TRAPS) are monogenic autoinflammatory diseases characterized by recurrent fever flares. METHODS: We randomly assigned patients with genetically confirmed colchicine-resistant familial Mediterranean fever, mevalonate kinase deficiency, or TRAPS at the time of a flare to receive 150 mg of canakinumab subcutaneously or placebo every 4 weeks. Patients who did not have a resolution of their flare received an add-on injection of 150 mg of canakinumab. The primary outcome was complete response (resolution…
Autoimmune hepatitis following hepatitis A virus infection.
1995
A 7-year-old patient is reported who suffered from fatigue and jaundice due to chronic hepatitis. He had acquired hepatitis A virus infection in his community and communicated the disease to his German family 4 weeks later. While the other family members recovered from acute viral hepatitis A, the patient presented 10 weeks after the onset of hyperbilirubinemia (12 mg/dl) with the histology of chronic hepatitis, absence of markers for viral persistence, presence of autoantibodies against smooth muscle (1:320) and the asialoglycoprotein receptor (1:600), and marked hypergammaglobulinemia (3700 mg/dl), leading to the diagnosis of autoimmune hepatitis. The patient received immunosuppressive th…
Mutations in the mu heavy-chain gene in patients with agammaglobulinemia.
1996
Most patients with congenital hypogammaglobulinemia and absent B cells are males with X-linked agammaglobulinemia, which is caused by mutations in the gene for Bruton's tyrosine kinase (Btk); however, there are females with a similar disorder who do not have mutations in this gene. We studied two families with autosomal recessive defects in B-cell development and patients with presumed X-linked agammaglobulinemia who did not have mutations in Btk.A series of candidate genes that encode proteins involved in B-cell signal-transduction pathways were analyzed by linkage studies and mutation screening.Four different mutations were identified in the mu heavy-chain gene on chromosome 14. In one fa…
Cryptic Insertions Of The Immunoglobulin Light Chain Enhancer Region Near CCND1 In T(11;14)-Negative Mantle Cell Lymphoma
2019
Cyclin D1+ mantle cell lymphoma (MCL) is molecularly characterized by the t(11;14)(q13;q32) or rearrangements of CCND1 gene with the immunoglobulin (IG) light chains.1,2 Most MCL can be diagnosed based on the characteristic pathologic features and cyclin D1 expression without the need for demonstrating the genetic translocation. However, in cases with atypical morphologic or phenotypic features other B-cell neoplasms that sometimes also have cyclin D1 positivity may be in the differential diagnosis.1 In these situations the detection of the CCND1 rearrangements may assist in the diagnosis since most other lymphomas do not carry translocations of the gene.3-7 A subset of plasma cell myelomas…
Is minor salivary gland biopsy more than a diagnostic tool in primary Sjorgren's syndrome? Association between clinical, histopathological, and molec…
2014
Objectives: Several histological scoring systems, including the focus score, performed in minor salivary glands (MSGs) by hematoxylin-eosin (H&E) staining, have been employed in clinical practice to assess the inflammatory infiltrate and provide the diagnosis of primary Sjorgren's syndrome (pSS). Aims of this study were to integrate different scoring systems and identify potential differences in the molecular profile of lymphoid cytokines related to germinal center (GC) formation and clinical subsets in pSS. Methods: Overall, 104 pSS patients and 40 subjects with sicca non-pSS were retrospectively evaluated. MSG biopsies were evaluated by H&E and immunofluorescence to assess histological pa…
Pathogenesis of Paraneoplastic Follicular Hyperkeratotic Spicules in Multiple Myeloma
1990
• We describe a 62-year-old man with multiple myeloma who developed horny spicules on his face, particularly on his nose. IgG-λ monoclonal gammopathy was detected, and the serum dysprotein was shown to be a cryoglobulin, which forms a cryogel at low temperatures. Light and electron microscopic and immunohistochemical examinations showed an intercellular precipitation and massive accumulation of the IgG dysprotein and cryoglobulin between the keratinocytes of the upper epidermis and the infundibular epithelium. The follicles were dilated and filled with parakeratotic cells, the protein deposits between them and a rudimentary hair thus resulting in the clinically visible symptoms of horny spi…
