It is characteristic of CRYOGLOBULINEMIA.Cryoglobulinemia: A condition characterized by the presence of abnormal quantities of CRYOGLOBULINS in the blood. Upon cold exposure, these abnormal proteins precipitate into the microvasculature leading to restricted blood flow in the exposed areas.Paraproteinemias: A group of related diseases characterized by an unbalanced or disproportionate proliferation of immunoglobulin-producing cells, usually from a single clone. These cells frequently secrete a structurally homogeneous immunoglobulin (M-component) and/or an abnormal immunoglobulin.Rheumatoid Factor: Antibodies found in adult RHEUMATOID ARTHRITIS patients that are directed against GAMMA-CHAIN IMMUNOGLOBULINS.Complement Activating Enzymes: Enzymes that activate one or more COMPLEMENT PROTEINS in the complement system leading to the formation of the COMPLEMENT MEMBRANE ATTACK COMPLEX, an important response in host defense. They are enzymes in the various COMPLEMENT ACTIVATION pathways.Antigen-Antibody Complex: The complex formed by the binding of antigen and antibody molecules. The deposition of large antigen-antibody complexes leading to tissue damage causes IMMUNE COMPLEX DISEASES.Vasculitis, Leukocytoclastic, Cutaneous: Disorder characterized by a vasculitic syndrome associated with exposure to an antigen such as a drug, infectious agent, or other foreign or endogenous substance. Its pathophysiology includes immune complex deposition and a wide range of skin lesions. Hypersensitivity or allergy is present in some but not all cases.Immunoglobulin G: The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.Complement C1q: A subcomponent of complement C1, composed of six copies of three polypeptide chains (A, B, and C), each encoded by a separate gene (C1QA; C1QB; C1QC). This complex is arranged in nine subunits (six disulfide-linked dimers of A and B, and three disulfide-linked homodimers of C). C1q has binding sites for antibodies (the heavy chain of IMMUNOGLOBULIN G or IMMUNOGLOBULIN M). The interaction of C1q and immunoglobulin activates the two proenzymes COMPLEMENT C1R and COMPLEMENT C1S, thus initiating the cascade of COMPLEMENT ACTIVATION via the CLASSICAL COMPLEMENT PATHWAY.Complement C3: A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.Complement C4: A glycoprotein that is important in the activation of CLASSICAL COMPLEMENT PATHWAY. C4 is cleaved by the activated COMPLEMENT C1S into COMPLEMENT C4A and COMPLEMENT C4B.Immunoglobulin M: A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT.

Clinical features include ANEMIA; HEMORRHAGES; and hyperviscosity.Nephritis: Inflammation of any part of the KIDNEY.Immunodiffusion: Technique involving the diffusion of antigen or antibody through a semisolid medium, usually agar or agarose gel, with the result being a precipitin reaction.Nephelometry and Turbidimetry: Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam.Lupus Erythematosus, Systemic: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.Antibodies, Antinuclear: Autoantibodies directed against various nuclear antigens including DNA, RNA, histones, acidic nuclear proteins, or complexes of these molecular elements. Antinuclear antibodies are found in systemic autoimmune diseases including systemic lupus erythematosus, Sjogren's syndrome, scleroderma, polymyositis, and mixed connective tissue disease.Complement System Proteins: Serum glycoproteins participating in the host defense mechanism of COMPLEMENT ACTIVATION that creates the COMPLEMENT MEMBRANE ATTACK COMPLEX. Included are glycoproteins in the various pathways of complement activation (CLASSICAL COMPLEMENT PATHWAY; ALTERNATIVE COMPLEMENT PATHWAY; and LECTIN COMPLEMENT PATHWAY).Hepatitis C: INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse.

Complement receptor 1 (CD35) on human reticulocytes: normal expression in systemic lupus erythematosus and HIV-infected patients. (1/235)

The low levels of complement receptor 1 (CR1) on erythrocytes in autoimmune diseases and AIDS may be due to accelerated loss in the circulation, or to a diminished expression of CR1 on the red cell lineage. Therefore, we analyzed the expression of CR1 on reticulocytes (R) vs erythrocytes (E). Healthy subjects had a significant higher CR1 number per cell on R (919 +/- 99 CR1/cell) than on E (279 +/- 30 CR1/cell, n = 23), which corresponded to a 3. 5- +/- 1.3-fold loss of CR1. This intravascular loss was confirmed by FACS analysis, which showed that all R expressed CR1, whereas a large fraction of E was negative. The systemic lupus erythematosus (SLE), HIV-infected, and cold hemolytic Ab disease (CHAD) patients had a CR1 number on R identical to the healthy subjects, contrasting with a lower CR1 on their E. The data indicated a significantly higher loss of CR1 in the three diseases, i.e., 7.0- +/- 3.8-, 6.1- +/- 2.9-, and 9.6- +/- 5.6-fold, respectively. The intravascular loss was best exemplified in a patient with factor I deficiency whose CR1 dropped from 520 CR1/R to 28 CR1/E, i.e., 18.6-fold loss. In one SLE patient and in the factor I-deficient patient, the FACS data were consistent with a loss of CR1 already on some R. In conclusion, CR1 is lost progressively from normal E during in vivo aging so that old E are almost devoid of CR1. The low CR1 of RBC in autoimmune diseases and HIV-infection is due to a loss occurring in the circulation by an active process that remains to be defined.  (+info)

Serious hazards of transfusion (SHOT) initiative: analysis of the first two annual reports. (2/235)

OBJECTIVE: To receive and collate reports of death or major complications of transfusion of blood or components. DESIGN: Haematologists were invited confidentially to report deaths and major complications after blood transfusion during October 1996 to September 1998. SETTING: Hospitals in United Kingdom and Ireland. SUBJECTS: Patients who died or experienced serious complications, as defined below, associated with transfusion of red cells, platelets, fresh frozen plasma, or cryoprecipitate. MAIN OUTCOME MEASURES: Death, "wrong" blood transfused to patient, acute and delayed transfusion reactions, transfusion related acute lung injury, transfusion associated graft versus host disease, post-transfusion purpura, and infection transmitted by transfusion. Circumstances relating to these cases and relative frequency of complications. RESULTS: Over 24 months, 366 cases were reported, of which 191 (52%) were "wrong blood to patient" episodes. Analysis of these revealed multiple errors of identification, often beginning when blood was collected from the blood bank. There were 22 deaths from all causes, including three from ABO incompatibility. There were 12 infections: four bacterial (one fatal), seven viral, and one fatal case of malaria. During the second 12 months, 164/424 hospitals (39%) submitted a "nil to report" return. CONCLUSIONS: Transfusion is now extremely safe, but vigilance is needed to ensure correct identification of blood and patient. Staff education should include awareness of ABO incompatibility and bacterial contamination as causes of life threatening reactions to blood.  (+info)

Modulation of renal disease in MRL/lpr mice genetically deficient in the alternative complement pathway factor B. (3/235)

In systemic lupus erythematosus, the renal deposition of complement-containing immune complexes initiates an inflammatory cascade resulting in glomerulonephritis. Activation of the classical complement pathway with deposition of C3 is pathogenic in lupus nephritis. Although the alternative complement pathway is activated in lupus nephritis, its role in disease pathogenesis is unknown. To determine the role of the alternative pathway in lupus nephritis, complement factor B-deficient mice were backcrossed to MRL/lpr mice. MRL/lpr mice develop a spontaneous lupus-like disease characterized by immune complex glomerulonephritis. We derived complement factor B wild-type (B+/+), homozygous knockout (B-/-), and heterozygous (B+/-) MRL/lpr mice. Compared with B+/- or B+/+ mice, MRL/lpr B-/- mice developed significantly less proteinuria, less glomerular IgG deposition, and decreased renal scores as well as lower IgG3 cryoglobulin production and vasculitis. Serum C3 levels were normal in the B-/- mice compared with significantly decreased levels in the other two groups. These results suggest that: 1) factor B plays an important role in the pathogenesis of glomerulonephritis and vasculitis in MRL/lpr mice; and 2) activation of the alternative pathway, either by the amplification loop or by IgA immune complexes, has a prominent effect on serum C3 levels in this lupus model.  (+info)

Cytoplasmic inclusions in leukocytes. An unusual manifestation of cryoglobulinemia. (4/235)

Cryoglobulins are circulating immunoglobulins characterized by reversible, cold-induced precipitation. A variety of laboratory abnormalities, including hypocomplementemia, elevated erythrocyte sedimentation rate, rheumatoid factor activity, pseudoleukocytosis, and pseudothrombocytosis, are associated with cryoglobulinemia. Extracellular, faintly basophilic, amorphous deposits of cryoglobulins occasionally have been described in blood smears. In the present study, smears prepared from blood collected at room temperature from 6 patients with cryoglobulinemia exhibited neutrophil and, occasionally, monocyte inclusions containing clear, light pink, or faintly basophilic amorphous material. The inclusions were absent in smears from blood collected and maintained at 37 degrees C. Ultrastructural examination revealed that the material within the leukocyte inclusions was consistent with phagocytosed immunoglobulins. The identification of characteristic cytoplasmic inclusions in leukocytes may be an important clue in the early recognition of cryoglobulinemia.  (+info)

Correlation between tumor induction and the large external transformation sensitive protein on the cell surface. (5/235)

The distribution on the cell surface of the large external LETS protein that is transformation sensitive of normal, transformed and tumorigenic cells was examined by immunofluorescent staining. A correlation was established between the expression of fibril-like LETS protein and the oncogenic capabilities of a series of adenovirus-transformed cell lines. In cells expressing a transformed phenotype in vitro, LETS protein is only detected in cell-cell contact areas, wheras in "untransformed" cells LETS protein is distributed over the cell surface. Transformed cells capable of inducing invasive tumors, and the cells of established tumor lines, have low or undetectable levels of LETS protein, as measured by this method. The results indicate that LETS protein has a role in cell-cell adhesion and that reduced expression of this protein at the cell surface is related to the oncogenic phenotype. This relationship has been established for experimentally induced and spontaneous tumors.  (+info)

Complement fixation by rheumatoid factor. (6/235)

The capacity for fixation and activation of hemolytic complement by polyclonal IgM rheumatoid factors (RF) isolated from sera of patients with rheumatoid arthritis and monoclonal IgM-RF isolated from the cryoprecipitates of patients with IgM-IgG mixed cryoglobulinemia was examined. RF mixed with aggregated, reduced, and alkylated human IgG (Agg-R/A-IgG) in the fluid phase failed to significantly reduce the level of total hemolytic complement, CH50, or of individual complement components, C1, C2, C3, and C5. However, sheep erythrocytes (SRC) coated with Agg-R/A-IgG or with reduced and alkylated rabbit IgG anti-SRC antibody were hemolyzed by complement in the presence of polyclonal IgM-RF. Human and guinea pig complement worked equally well. The degree of hemolysis was in direct proportion to the hemagglutination titer of the RF against the same coated cells. Monoclonal IgM-RF, normal human IgM, and purified Waldenstrom macroglobulins without antiglobulin activity were all inert. Hemolysis of coated SRC by RF and complement was inhibited by prior treatment of the complement source with chelating agents, hydrazine, cobra venom factor, specific antisera to C1q, CR, C5, C6, or C8, or by heating at 56 degrees C for 30 min. Purified radiolabeled C4, C3, and C8 included in the complement source were bound to hemolysed SRC in direct proportion to the degree of hemolysis. These data indicate that polyclonal IgM-RF fix and activate complement via the classic pathway. The system described for assessing complement fixation by isolated RF is readily adaptable to use with whole human serum.  (+info)

Cryofibrinogenaemia: a study of 49 patients. (7/235)

The purpose of this study was to characterize the clinical features and components of 30 patients with isolated cryofibrinogen (CF) versus those of 19 patients with combined CF and cryoglobulins (CG). Secondary forms of cryofibrinogenaemia associated with collagen disorders, infectious or malignant diseases, were significantly more frequent in patients with combined CF and CG than those with isolated CF (79 versus 47%, P = 0.02). Both groups of CF patients presented predominantly cutaneous symptoms (77% in isolated CF; 58% in combined CF + CG), and less frequently venous and/or arterial thrombosis (13% in isolated CF; 3% in combined CF + CG). Patients with idiopathic forms of CF, and particularly those without CG, suffered essentially from recurrent painful skin ulcers, mainly triggered by cold exposure. Patients with isolated CF had higher mean plasma concentrations of CF than those with combined CF + CG (1. 61 +/- 1.26 versus 0.82 +/- 1.18 g/l, respectively; P = 0.004), but there was no correlation between the CF plasma level and either the severity of symptoms or the sensitivity to cold. In patients with isolated CF, fibronectin was suggested (by precipitation analysis) to be a major component of the cryoprecipitate, whereas immunoglobulins were rarely present (in only three out of 30 patients). By contrast, in the majority of patients (78%) with combined CF and CG, the CF consisted mainly of immunoglobulins of the same class as those characterizing the associated CG. Analysis of the CG precipitate revealed the presence of fibronectin but not fibrinogen, alpha1-antitrypsin and alpha2-macroglobulin. In conclusion, isolated and combined cryofibrinogenaemia are associated with different clinical signs requiring different clinical management, but there is no evidence as yet for a causal role of the cryoprecipitates in the differences observed.  (+info)

Specific concentration of polynucleotide immune complexes in the cryoprecipitates of patients with systemic lupus erythematosus. (8/235)

Although the association of cryoglobulinemia with hypocomplementemia and tissue injury in systemic lupus erythematosus is well recognized, composition of cryoprecipitates in terms of circulating antigens and antibodies in this disease is less clear. To clarify this question, cryoprecipitates from patients with SLE were examined with sensitive assay techniques for certain antipolynucleotide antibodies and DNA antigen. DNA antibodies were highly enriched relative to serum levels in the majority of cryoprecipitates. DNA antigen was also demonstrable. Antibody to ribonucleoprotein, although less frequently present, was similarly enriched in certain cryoprecipitates. In contrast, anti-double strand RNA, which was commonly detectable in relatively high titer in serum, was only minimally concentrated in a minority of cryoprecipitates. Absorption experiments using red blood cells heavily coated with polynucleotide antigen indicated that a major proportion of the IgG in certain cryoprecipitates was specific antibody. The data strongly suggest that the cryoprecipitates in systemic lupus erythematosus represent circulating immune complexes that are soluble at 37 degrees C and come out of solution in the cold. The marked concentration of immune complexes in the cryoglobulin offers a simple and direct method for determination of the nature of the complexes. The accumulated evidence obtained in the present study indicates that these complexes closely reflect, in their composition, the circulating immune complexes which are most significant pathogenetically in renal tissue injury.  (+info)

PY - 1977/1/1. Y1 - 1977/1/1. N2 - A purified human monoclonal IgM(κ) (cold agglutinin MKV) has been characterized as both a cold agglutinin and a cryoglobulin. Since its reactivity with human erythrocytes but not with dog erythrocytes is reduced by treatment of the cells with ficin and its reactivity with both is abolished by treatment of the cells with neuraminidase, it has by definition Pr2 specificity [Roelcke, D. (1974) Clin. Immunol. Immunopath. 2, 266-280]. Presumably, the membrane receptors for cold agglutinin MKV are sialic acid-containing glycoproteins in human cells and sialic acid-containing glycolipids in dog cells. Agglutination of erythrocytes is specifically inhibited by II3-N-acetylneuraminosyllactosylceramide (GM3) and N-acetylneuraminosylparagloboside but not by their ...

Doctors give unbiased, helpful information on indications, contra-indications, benefits, and complications: Dr. Munshower on cryoglobulin serum: It is very important to know why these were drawn in what sounds to be an otherwise healthy 19 year old. Did you expect to find something wrong?
The AASLD-IDSA guidance includes a list of liver-related complications and extrahepatic diseases that qualify patients for high priority treatment. In my practice, we have instituted routine additional screening based on that list to help seek out potentially hidden risk factors for disease complications. For example, we now screen every patient with HCV infection for cryoglobulins. Cyroglobulinemia can have obvious end-organ manifestations such as vasculitis or renal failure. However, patients who have cyroglobulins without immediate symptoms are still at risk for developing complications in the near future. Thus, we seek to document any evidence of cryoglobulins and highlight the associated risk for developing extrahepatic manifestations. In addition, we perform a urinalysis on all patients to look for evidence of proteinuria or microscopic hematuria. Of importance, there are HCV-related renal diseases that are not cryo related, including membranous glomerulonephritis. Performing routine ...

BACKGROUND:Mixed cryoglobulinaemia (MC), a systemic vasculitis associated with hepatitis C virus (HCV) infection in ,90% of cases, is frequently complicated by multiple organ involvement. The prevalence of thyroid disorders in MC has not yet been studied. AIM:To investigate the prevalence and clinical features of thyroid involvement in patients with HCV-associated MC (HCV + MC). DESIGN:Case-control study. METHODS:HCV + MC patients (n = 93, 17 men and 76 women, mean +/- SD age 63 +/- 10 years, mean disease duration 14 +/- 7 years) consecutively referred to the Rheumatology Unit were matched by sex and age (+/- 2 years) to (i) 93 patients with chronic C hepatitis (CH) without MC and (ii) 93 healthy (HCV-negative) controls from the local population. Measurements included prevalence of hypo- or hyperthyroidism, thyroid autoantibodies, thyroid nodules and thyroid cancer. RESULTS:By McNemars chi(2) test, the following thyroid abnormalities were significantly more frequent in HCV + MC patients than in ...
We describe a patient being investigated for anaemia where the lipaemia index on a Beckman Coulter DxC800 analyser was markedly elevated and out of keeping with the visual appearance of the serum. Subsequent investigation revealed a monoclonal IgM kappa immunoglobulin with type I cryoglobulin behaviour. The patient was then diagnosed with a non-Hodgkin B-cell lymphoma. We later identified a second patient with a similar anomalous index with an IgM lambda paraprotein, and a known marginal zone splenic lymphoma but were unable to confirm cryoglobulin behaviour prior to treatment. A review of 50 consecutive IgM paraproteins revealed no other anomalous lipaemia indices. We postulate that it is the properties of the paraprotein that determine its cryoglobulin behaviour that also render it susceptible to precipitation in the index diluent, not the fact of it being an IgM paraprotein per se. This appears to be the first reported case of a paraprotein identified following an anomalous lipaemia ...
The extrahepatic manifestations of hepatitis C were reviewed in the November issue of Cleveland Clinic Journal of Medicine. The review points out that cryoglobulinemia is the most strongly associated manifestation. Most cases of what was formerly called essential mixed cryoglobulinemia are in fact due to hepatitis C. Most patients with circulating cryoglobulins are asymptomatic, with about 10% manifesting the typical features of purpura, arthralgia, renal disease and neuropathy, according to the review ...
In recent years, the search for a substitute to cancellous bone autograft in large bone defects has focused on composite materials. Several parameters such as the nature of the conductive material, differentiation state of implanted cells, and the local supplementation in growth factors have been shown to be crucial in bone repair. Owing to the number of parameters to be tested, their relative importance and interactions still require further basic research. We focused our study on a blood-derived product as an easily available source of clinical-grade growth factors: a platelet glue obtained from cryoprecipitation of apheresis platelet products (PGCAP). We showed that, in vitro, PGCAP enhanced both proliferation and osteoblastic differentiation of bone marrow-derived MSCs. We confirmed these results by demonstrating the ability of PGCAP to improve ectopic bone formation in mice after implantation of MSC-loaded biphasic biomaterials. Interestingly, we showed that this approach was more efficient ...

Specimen Collection and Handling: Cryoglobulins come out of solution below body temperature. Serum must be obtained from clotted blood maintained at body temperature, from time of withdrawal. If blood is kept at lower temperatures, the cryoprecipitate may centrifuge out with the blood clot. The following procedure must be followed or the specimen is NOT acceptable.. CAUTION: Specimen is not acceptable when drawn on a patient receiving heparin or any other anti-coagulant. When a Dialysis/Apheresis patient has a catheter with heparin, 10 ml or more must be wasted (discarded) before specimen for Cryoglobulin is drawn. Peripheral stick is preferred. (Heparin is anti-Complementary and will therefore breakdown the Cryo immune complexes which contain complement producing a false negative or reduced Cryocrit.) Other anti-coagulants chelate Ca and deplete complement. Prepare transporting chamber: Select a receptacle that will maintain a fairly constant temperature. (Patients styrofoam pitchers with lids ...
Results 661 patients were selected. Group 1 comprised 40/661 (6.1%), group 2 comprised 17/661 (2.6%), group 3 comprised 180/661 (27.2%), and group 4 comprised 424 (64.1%). Anti-La, hypergammaglobulinemia (IgG , 16 g/l), leucopoenia (,3000/mmc), rheumatoid factor, serum monoclonal component, low C3, low C4, and cryoglobulinemia were selected by univariate analyses.

To the editor: In connection with the article by Vogelzang and associates (1) on Raynauds phenomenon and its relation to vinblastine-bleomycin therapy, we wish to describe a new case.. A 41-year-old man with an embryonal carcinoma in the mediastinum developed Raynauds phenomenon with distal necrosis in the third month of treatment with vinblastine, bleomycin, and cisplatin (2). An arteriogram showed multiple arterial occlusions; the findings of a rheumatologic diagnostic study (including cryoglobulins) were negative. He smoked, but had never before had Raynaud manifestations. The severe pain was relieved only with intra-arterial vasodilators.. This case calls attention to vinblastine-bleomycin as a ...

Treatment:. Patients with few clinical symptoms and mild anemia may not require treatment but only avoidance of cold. Keeping the patient warm may be sufficient treatment. Treat any underlying infection e.g. Clarithromycin or Azithromycin for Mycoplasma pneumoniae.. Anemia is generally mild. Only patients who have serious symptoms related to anemia or have a Raynaud-type syndrome that constitutes a threat to life or quality of life require active therapy.. Folic acid supplements for prevention and treatment of folate deficiency should be considered.. The disease is usually refractory to corticosteroids.. Rituximab may be an option for treatment in some cases.. In the presence of underlying lymphoma, chlorambucil or oral cyclophosphamide may be helpful.. Splenectomy is usually ineffective for the treatment of cold agglutinin disease, because the liver is the predominant site of sequestration. However, if the patient has splenomegaly, then the disease may respond to splenectomy. More importantly, ...

Acrocyanosis is the bluish discoloration of the skin that occurs especially in the hands and feet. It can also affect the ears, nose, and nipples.
Waldenströms macroglobulinaemia is an uncommon, low grade, small cell lymphoma with monoclonal IgM production. This protein accounts for the increased plasma viscosity often seen in this disease, and causes some of the most frequent symptoms. Other less common protein complications include cold agglutinin haemolytic anaemia, peripheral neuropathy, amyloidosis, and cryoglobulinaemia.5. The term cryoglobulinaemia refers to the presence in the serum of one or more immunoglobulins that precipitate reversibly at a temperature below 37°C. According to Brouet et al,4 cryoglobulins can be classified on the basis of their immunoglobulin composition as type I, consisting of a monoclonal immunoglobulin alone; type II, as a mixture of monoclonal and polyclonal immunoglobulins; and type III, consisting of polyclonal immunoglobulins. They are found in small quantities in normal serum,6 but in large concentrations in many pathological conditions. Whereas type III cryoglobulinaemia is mainly noted as the ...
肺炎支原體(Mycoplasma pneumoniae、黴漿菌性肺炎)是一種可導致肺炎的支原體細菌,也有機會導致冷凝集素症(cold agglutinin disease)。這種由肺炎支原體引起的肺炎,又稱作黴漿菌性肺炎,盛行於學齡兒童。. 大多數患者只有輕微上呼吸道感染,有咳嗽、發燒、喉嚨痛、頭痛及疲倦等徵狀,有些患者有肺外症狀像是皮膚紅疹,嚴重者則可能患上肺炎,屬於非典型肺炎的一種。. 輕微黴漿菌性肺炎大多是自限性,不需藥物治療。但嚴重住院者,由於黴漿菌性肺炎不能用一般的肺炎藥來醫治,即使兒童感染了黴漿菌性肺炎,也只能用原來用於醫治成人肺炎的強效藥物來醫治,舉例來說,可以使用Macrolides類的抗生素像是Azithromycin。. ...

Hepatitis C virus (HCV) infection is the major cause of mixed cryoglobulinaemia (MC), an immune complex (IC)-mediated systemic vasculitis mainly involving the small blood vessels. The precise mechanism of cryoprotein production is currently unknown. HCV virions and non-enveloped core protein participate in the formation of cold-insoluble ICs. Cryoglobulinaemic patients represent a distinct HCV-infected population, in that significant HCV enrichment of lymphoid cells is accompanied by evidence of productive virus infection and increased frequency of B cells. Liver, the major target organ of HCV, is the site of accumulation of inflammatory infiltrates that shares many architectural features with lymphoid tissue and reflects a distorted homeostatic balance between factors that enhance cellular recruitment, proliferation and retention, and those that decrease cellularity (cell death and emigration). There is now overwhelming evidence of a direct contribution to B-cell growth and survival through ...

The term cryosupernatant (also called cryo-poor plasma , cryoprecipitate depleted ) refers to plasma from which the cryoprecipitate has been removed. Components The resulting plasma has reduced levels of factor VIII (FVIII), von Willebrand factor (VWF), factor XIII (FXIII), fibronectin and fibrinogen . While the levels of FVIII are greatly reduced, levels of fibrinogen can be as much as 70% of original levels. Uses Cryosupernatant plasma can be used when replacement of FVIII is not required, and is indicated for plasma exchange for patients with thrombotic thrombocytopenic purpura (TTP) as well as for treatment of hemolytic-uremic syndrome (HUS) by plasma exchange, when plasma exchange is indicated.

1 site; and 6) renal disorder. Additional criteria: 1) typical biopsy findings at site(s) of involvement and 2) angiogram evidence of occlusion in one or more small to medium sized arteries. The diagnosis of secondary cryofibrinogenemia also requires evidence for the cited infectious, malignant, premalignant vasculitis, and autoimmune disorders while the diagnosis of primary cryofibriongenemia requires a lack of evidence for 1) the cited associated disorders, 2) other vascular occlusive diseases, and 3) cryoglobulinemia. Studies on the treatment of cryofibrinoginemic disease have involved relatively few patients, are limited primarily to case reports, and differ based on whether the disease is primary or secondary. In all cases of cryofibrinogenemic disease, however, patients should avoid the exposure of afflicted body parts to cold weather or other environmental triggers of symptoms and avoid using cigarettes or other tobacco products. In severe cases, these individuals also risk developing ...
Cold Agglutinin hemolytic anemia due to cold autoantibodies associated with Mycoplasma pneumoniae is rare. Optimal treatment includes antibiotics and maintenance of a constant warm environment for the patient. This treatment, however, may result in a prolonged, costly, and confining hospitalization.. We report the use of an environmental suit for a patient with severe hemolysis due to M. pneumoniae pneumonia. This suit provides a constant temperature and has enabled the patient to journey outside his room, despite winter temperatures, yet avoid further hemolytic episodes. Early discharge was possible and has facilitated the patients return to home and work as well as ...
The diagnostic approach to splinter hemorrhages follows the differential diagnosis that has been outlined above. Sometimes the diagnosis is obvious. But when it is not a thorough investigation for the various potential causes should be undertaken. A common approach includes blood tests and imaging studies. Examples of relevant preliminary blood tests includes a complete blood count, basic metabolic panel, markers of inflammationsuch as erythrocyte sedementation rate, culture bottles to look for endocarditis and a screen for vasculitis such as ANA, complement levels and cryoglobulins. Typical imaging studies often include a trans-thoracic echocardiogram to look for a central thrombus and some imaging of the chest. In the case of splinter hemorrhages in the fingers imaging may include a chest CT angiogram and an arterial duplex ultrasound of the affected arms with thoracic outlet maneuvers.. These studies are just suggestions. Also, further imaging and laboratory tests should obviously stem from ...

A nudivirus (family Nudiviridae) is a large, rod-shaped virus with a circular, double stranded DNA genome of 96-231 kb. The genome encodes 98 to 154 open reading frames. Virions are rod-shaped and when enveloped are up to 382×77 nm. The word "nudivirus" comes from the Latin nudus, which means naked and virus, poison. Naked refers to the fact that, unlike baculoviruses, they are not occluded by cryoproteins. In 2007, the genus Nudivirus was proposed to include viruses similar to the Oryctes rhinoceros virus (Wang et al., 2007b). The nudiviruses were classified as the family Nudiviridae in 2013. All 3 sequenced nudivirus have 33 open reading frames in common. Gene content comparaison and phylogenetic analyses show that Nudivirus share 20 cores genes with baculovirus and form a monophyletic sister group with them. Fossil calibration estimate this association arose 100 million years ago(Mya), while the last common ancestor of BVs, nudivirus, and baculovirus existed approximately 312 Mya. ...

... , also called hypersensitivity vasculitis, describes inflammation of small blood vessels. The term leukocytoclastic refers to the debris of neutrophils (immune cells) within the blood vessel walls. The disease can be confined to the skin (cutaneous) or it can affect many different organs of the body such as the kidneys, central nervous system, heart, gastrointestinal tract, and lungs. An allergic reaction to drugs, food, or food additives supports the theory of the immune system playing the dominant role. Infections, inflammatory bowel disease, rheumatoid arthritis, lupus erythematosus, Sjögren syndrome, and less often malignancy are some of the various conditions associated with the vasculitis. In the skin, damaged blood vessels become leaky and small areas of hemorrhage appear as purple-red, raised lesions known as palpable purpura. Multiple discrete or grouped lesions are commonly found on the legs or other dependent areas of the body. These lesions are usually ...
The role of hepatitis C virus (HCV) infection in the induction of type II mixed cryoglobulinemia (MCII) and the possible establishment of related lymphoproliferative disorders, such as B-cell non-Hodgkin lymphoma (B-NHL), is well ascertained. However, the molecular pathways involved and the factors predisposing to the development of these HCV-related extrahepatic complications deserve further consideration and clarification. To date, several host- and virus-related factors have been implicated in the progression to MCII, such as the virus-induced expansion of selected subsets of B-cell clones expressing discrete immunoglobulin variable (IgV) gene subfamilies, the involvement of complement factors and the specific role of some HCV proteins. In this review, we will analyze the host and viral factors taking part in the development of MCII in order to give a general outlook of the molecular mechanisms implicated.

(Standard deviation of RBC. volume/mean MCV) X 100. The normal value for RDW is 11.5% to 14.5%. The standard deviation of red cell volume is derived from size histogram data that plot red cell size after a large number of red cells has been analyzed by the instrument. The usefulness of the RDW is that in many cases the RDW will become abnormal earlier in the anemia process than the MCV Because many anemias (like iron deficiency anemias) develop over a period of time, this parameter may provide a sensitive indicator of red blood size change16 before the red cell indices become overtly abnormal..

Membranoproliferative glomerulonephritis (MPGN) is a relatively-rare, immune-mediated glomerular disease. There is no accepted therapy and all current therapies are inadequate. Current therapeutic options include immunosuppression with corticosteroids alone or in combination with alkylating agents, antiplatelet therapy with aspirin and/or dipyridamole and/or warfarin, and angiotensin converting enzyme inhibitors and/or angiotensin receptor blockers. As with other glomerular diseases the amount of protein in the urine correlates well with the long-term prognosis. Thus, this parameter has been used in previous studies, and will be used in this study, as the primary indicator of therapeutic efficacy. We propose a pilot study to test the hypothesis that selective B lymphocyte depletion will result in disappearance of pathogenic antibodies and induce remission of proteinuria in patients with idiopathic membranoproliferative glomerulonephritis. Our population will be 10 adults with MPGN involving ...
This study aimed to delineate the clinical spectrum of CN in a large series of patients diagnosed with clinical criteria. Although nerve biopsy is the gold standard for diagnosis of CN,4 we think that the diagnosis can be determined confidently in most patients using clinical criteria, encompassing the entire spectrum of CN, including the mild forms of neuropathy. The use of nerve biopsy, which is an invasive procedure, should be restricted to patients with severe and/or progressive forms, who may require aggressive treatment.. In our study the clinical features of patients with or without comorbidity were quite similar. This suggests that cryoglobulinaemia usually has a distinct impact on neuropathic manifestations, even in the presence of concurrent diseases. Our data showed that in most of our cases CN was a sensory neuropathy and only rarely a mononeuritis multiplex. It mainly affected women in the sixth and seventh decades, and it was the initial manifestation of mixed cryoglobulinaemia in ...
In a series of 215 patients with WM, Merlini et al.46 reported the clinical presence of peripheral neuropathy in 24% of WM patients, although prevalence rates ranging from 5% to 38% have been reported in other series.47,48 An estimated 6.5 10% of idiopathic neuropathies are associated with a monoclonal gammopathy, with a preponderance of IgM (60%) followed by IgG (30%) and IgA (10%) (reviewed in Nemni et al49 and Ropper and Gorson50). In WM patients, the nerve damage is mediated by diverse pathogenetic mechanisms: IgM antibody activity toward nerve constituents causing demyelinating polyneuropathies; endoneurial granulofibrillar deposits of IgM without antibody activity, associated with axonal polyneuropathy; occasionally by tubular deposits in the endoneurium associated with IgM cryoglobulin and, rarely, by amyloid deposits or by neoplastic cell infiltration of nerve structures.51 Half of the patients with IgM neuropathy have a distinctive clinical syndrome that is associated with antibodies ...

Hepatitis C virus (HCV) is associated with the B-cell lymphoproliferative disorders mixed cryoglobulinemia (MC) and non-Hodgkin lymphoma. We have previously reported that HCV(+)MC(+) patients have clonal expansions of hypermutated, rheumatoid factor-bearing marginal zone-like IgM(+)CD27(+) peripheral B cells using the V(H)1-69 gene. Here we coupled transcriptional profiling with immunophenotypic and functional studies to ascertain these cells role in MC pathogenesis. Despite their fundamental role in MC disease, these B cells have overall transcriptional features of anergy and apoptosis instead of neoplastic transformation. Highly up-regulated genes include SOX5, CD11C, galectin-1, and FGR, similar to a previously described FCRL4(+) memory B-cell subset and to an exhausted, anergic CD21(low) memory B-cell subset in HIV(+) patients. Moreover, HCV(+)MC(+) patients clonal peripheral B cells are enriched with CD21(low), CD11c(+), FCRL4(high), IL-4R(low) memory B cells. In contrast to the functional,

In the skin, damaged blood vessels become leaky and small areas of hemorrhage appear as purple-red, raised lesions known as palpable purpura. Multiple discrete or grouped lesions are commonly found on the legs or other dependent areas of the body. These lesions are usually asymptomatic but can be itchy or painful. Large, painful, ulcerated blisters are indicative of more severe vessel inflammation. Lesions are present for 1 to 4 weeks on average before healing (often with some residual scarring). Signs of systemic involvement include fever, muscle aches, joint pain, blood in the urine or stool, abdominal pain, vomiting, cough, numbness, and weakness.. A physician can usually make the diagnosis based on the characteristic clinical presentation. A punch biopsy from one of the lesions can confirm the diagnosis. Additional tests are necessary to rule out associated systemic diseases. Tests to consider include a complete blood count, urinalysis, serum chemistry panel, rheumatoid factor, hepatitis ...
A 73-year-old man with Hashimotos thyroiditis (HT) suffered from purpura on the lower legs. He was diagnosed with IgG4-related disease (IgG4-RD) with serum IgG4 elevation and dacryo-sialadenitis confirmed histologically. Serum Th2 and Treg cytokines, interleukin 7 (IL7), IL8 and Th2 chemokine levels were elevated, while skewed Th1 balance was seen in fluorescence-activated cell sorting (FACS). Therefore, preferential Th1 balance in HT appeared to be followed by IgG4-RD characterized with Th2 and Treg polarization. The commencement of steroid therapy dramatically exacerbated clinical manifestations including IgG4-RD-associated HT. The measurement of cytokine and chemokine levels as well as FACS analysis in the development of IgG4-RD seemed to be beneficial. In conclusion, an innovative association of HT, IgG4-RD and vasculitis was observed. This report also offers novel diagnostic and therapeutic approaches for IgG4-RD. ...

The results of Richards biopsy are in. He has Leukocytoclastic Vasculitis, or LCV. We already pretty much knew he had vasculitis, but needed the diagnosis before they can proceed with more tests to see whats causing it. Basically, there is a 50% chance its caused by an autoimmune disorder or medication or something hes eating, and theres a 50% chance theyll never know whats causing it. It could be caused by Lupus, Rheumatoid Arthritis, or Hepatitis C, or it could be due to his thyroid medication (the doctor doesnt think so), or….maybe my cooking? Okay, humor does help in times like these. Honestly, were praying its nothing serious and that well never know what causes it.

TY - JOUR. T1 - Fatal cerebral hemorrhage in a patient with CD19-positive Igm-producing aggressive plasma cell myeloma, hyperviscosity syndrome and cryoglobulinemia. AU - Alatoom, Adnan. AU - Elsabrouty, Rania. AU - Willis, Jason. AU - Boils, Christie. AU - Sarode, Ravindra. AU - Hashim, Ibrahim. AU - Wang, Huan You. PY - 2009. Y1 - 2009. N2 - IgM plasma cell myeloma (PCM) is a rare entity, and CD19 positivity is found in only 1-4% of PCM. Here we report a unique case of IgM PCM, in which the plasma cells are positive for CD19. Clinically, the patient presented with hyperviscosity syndrome, mimicking the clinical manifestation of Waldenstroms macroglobulinemia. In addition, the IgM para-protein from the patient behaved like cryoglobulins, which interfered with some of the laboratory measurements and resulted in erroneous platelet count, mean platelet volume, and serum IgM level. Despite chemotherapy, the PCM persisted and progressed to plasma cell leukemia, and the patient died of a left ...
Erythrophagocytosis by monocytes or macrophages is occasionally seen in hematologic malignancy, autoimmune hemolytic anemia, and hemophagocytic lymphohistiocytosis [12]. However, erythrophagocytosis by neutrophils on the peripheral blood smear is an unusual morphological phenomenon. Erythrophagocytosis by neutrophils has been reported in patients with some hemolytic anemias, particularly paroxysmal cold hemoglobinuria (PCH), and other conditions including poisoning with potassium chlorate, sickle cell disease, and incompatible transfusion [3456]. Cases of erythrophagocytosis by neutrophils have rarely been observed in cold agglutinin disease (CAD) [789]. We report a female patient with CAD and the presence of erythrophagocytosis by neutrophils on the peripheral blood smear.. An 80-year-old woman was referred to our hospital because of dizziness. A few days prior to referral, she had cold symptoms, with a cough and rhinorrhea. She had a history of hypertension. Physical examination revealed ...

In Europe, patients who are bleeding out receive fibrinogen concentrate, a dried and purified form of the protein that is dissolved in water before being infused into the patient. Here in North America, patients with low levels of the clotting factor receive cryoprecipitate, a frozen blood product derived from donated plasma. Unlike fibrinogen concentrate, the golden honey-coloured cryoprecipitate contains a mixture of fibrinogen and other clotting factors. More concerning, however, is that cryoprecipitate is not treated to kill any viruses that might be present in the original donor plasma.. "European governments decided that cryoprecipitate was not safe because its not virally inactivated," says Callum, who is also an assistant professor in the department of laboratory medicine and pathobiology at U of T. "That obviously makes physicians in North America, the U.K. and Australia uncomfortable, because were still using cryoprecipitate when other countries have switched to blood products that ...
