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.
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 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)

TY - JOUR. T1 - A Waldenstrom macroglobulin that is both a cold agglutinin and a cryoglobulin because it binds N-acetylneuraminosyl residues. AU - Tsai, C. M.. AU - Zopf, D. A.. AU - Yu, Robert K. 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 ...

In successive checkups in our offices, the patient showed improvement in terms of ischemia but polyarthritis persisted. The result for cryoglobulins was positive. Given the persistence of polyarthritis (although she continued to take MTX and leflunomide) and cryoglobulinemia, it was decided that she begin rituximab. Anticoagulation was maintained with acenocoumarol for a year, until the cryoglobulins were negative, when antiplatelet therapy was begun with ASA. During follow-up, the patient was repeatedly positive for ANA at low titers, with a homogeneous pattern, and was negative for anti-dsDNA. The immunological study was extended and we found antinucleosome antibodies and antibodies against the collagen-like region of C1q. The patient has continued to take rituximab, MTX, HCQ and ASA. She has not had any further ischemic episodes and there is no evidence of involvement of kidneys or of any other organ.. Discussion. We report the case of a patient with polyarthritis, a frequent cause for ...
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 ...

Fulminant gangrene of the fingers, toes and nose developed in a 57-year-old woman with Escherichia coli pneumonia. Cryoglobulinemia was noted, and the cryoglobulin was identified as IgM-IgG with anti-I cold agglutinin activity. The cold agglutinins possessed potent lymphocytotoxic and monocytotoxic activity and weaker granulocytotoxic activity. Treatment with plasmapheresis, steroids and antibiotics led to complete clinical recovery, although amputation of several toes was necessary. The patient died 1 1/2 years later; the main findings at autopsy were chronic and acute pyelonephritis and acute bacterial endocarditis. This seems to be the first case of IgM-IgG cold agglutinemia occurring during the course of E. coli infection and the third case of fulminant gangrene complicating transient cold agglutinemia.. ...
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.

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 ...

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 ...

DelveInsights Cold Agglutinin Disease (CAD) - Epidemiology Forecast 2030 report delivers an in-depth understanding of the disease, historical, and forecasted epidemiology of Cold Agglutinin Disease (CAD) in the United States, EU5 (Germany, France, Italy, Spain, and the United Kingdom), and Japan.
Here are some tips for warming up quickly after being outside in cold weather, or stuck in a chilly room, and you have cold agglutinin disease.
Cold Agglutinin Disease is a rare type of autoimmune hemolytic anemia (AIHA)in which the bodys immune system mistakenly attacks and destroys its own red blood cells. This causes red blood cells to be prematurely destroyed (hemolysis) leading to anemia and other associated signs and symptoms such as extreme fatigue, muscle weakness, trouble breathing, dizziness, rapid heartbeat and pulse, bluish skin and pain, particularly in areas exposed to the cold. CAD patients are more susceptible to blood clots, strokes, and heart issues than the average person ...
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, ...
Read suggestions for keeping warm when its cold out, because cold weather can aggravate or add to CADs symptoms, like triggering Raynauds syndrome.
We retrospectively studied 232 patients with cold agglutinin disease (CAD) at 24 centers in five countries. In Norway and a northern region of Italy, the study was close to being population-based. For the first time, we demonstrate 4-fold differences between cold and warmer climates regarding prevalence (20 versus 5 cases/million) and incidence (1.9 versus 0.48 cases/million/year). Mean baseline hemoglobin level was 9.3 g/dL, but 27% had hemoglobin , 8 g/dL. Identification of typical features of CAD-associated lymphoproliferative disorder in the bone marrow was greatly increased by centralized biopsy assessment. CAD seems to be associated with a slightly increased risk of venous thrombosis. This work included a follow-up study of therapies, focusing on the long-term outcomes of the rituximab plus bendamustine and rituximab plus fludarabine regimens. Rituximab plus bendamustine therapy resulted in responses in 35 (78%) of 45 patients; 24 (53%) achieved complete response. Interestingly, these ...

WALTHAM, Mass.--(BUSINESS WIRE)-- Bioverativ Inc., a Sanofi company dedicated to transforming the lives of people with rare blood disorders, today announced results from a new, population-based retrospective study that found a greater than twofold increased risk of mortality in people with cold agglutinin disease (CAD) within the first five years after diagnosis. The study, which is the first to compare overall survival among people with CAD with that of the general population, also showed that the increased risk of mortality and life-threatening thromboembolic events (TEs) such as stroke and heart attack was evident starting in the first year after diagnosis. These data were presented at the 23rd Annual Congress of the European Hematology Association (EHA). The results of our survival analysis contribute to the growing body of evidence that indicate that CAD is a more severe disease than previously thought, said Sigbjørn Berentsen, MD, PhD, Consultant Hematologist, Department of Research and ...

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 ...

Cold agglutinin disease What every physician needs to know: Cold agglutinin disease (CAD) is a rare (approximately 1:100,000) disorder in which a red cell autoantibody, primarily IgM (immunoglobulin M), fixes complement in vivo. Complement fixation preferentially occurs at temperatures below 37°C, hence the term CAD. This results in mostly extravascular hemolytic anemia, but intravascular hemolysis…. ...
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 following laboratory tests should be conducted to rule out other causes of Raynaud phenomenon and neuropathy: complete blood count, erythrocyte sedimentation rate, and measurement of antinuclear antibody, rheumatoid factor, cryoglobulin, cold agglutinin, random glucose, thyroid-stimulating hormone, vitamin B12, and red blood cell folate levels.16. If HAVS is suspected, patients should be referred to an occupational medicine specialist for further investigations, especially if symptoms are severe or if work-related compensation is sought. Although there is currently no standardized diagnostic test for HAVS,2 additional investigations might be ordered by specialists to objectively measure severity, rule out other causes, and guide management. Objective evidence of the condition might also facilitate compensation claims and the implementation of workplace modifications.. Vascular assessments might include digital plethysmography, which detects differences in finger pulse waveforms before and ...
