Septic arthritis of the foot is a type of medico-surgical emergency where rapidity in diagnosis and treatment is essential to limit functional and sometimes fatal damage, and where microbiologic diagnosis is essential and imperative.

In patients with acute arthritis, a high suspicion of septic arthritis is mandatory, because the joint can be destroyed if the treatment is postponed for a few days.
Patients with advanced age, immune suppression due to the disease itself or immunosuppressive therapy and abnormal joint structure or joint prosthesis are in an increased risk for joint infection (Table 2).
No universal agreement of classification and diagnostic criteria are available for reactive arthritis, which was originally defined as arthritis developing soon after or during an infection elsewhere in the body, but in which the micro-organism does not enter the joint. Microbes associated with reactive arthritis are Gram-negative lipopolysaccharide-containing bacteria, all intracellular pathogens. Chlamydia trachomatisA is by far the most common cause of genital infection and also the most common triggering infection for reactive arthritis. Genetic factors for the susceptibility can partially explain the fact that only 1-15 % of the infected subjects develop reactive arthritis. The classical bacteria capable to trigger reactive arthritis are gram-negative obligate or facultative intracellular aerobic bacteria with a lipopolysaccharide-containing outer membrane. After invasion via mucosal route, the microbes persist either in the epithelium or within associated lymphoid tissues, liver and spleen.
While HLA-B27 is not required for the development of reactive arthritis, its presence is contributing to the chronicity of the disease.
There is usually a delay of 1-2 weeks from the start of infection to the onset of musculoskeletal symptoms. Patients have typically asymmetric oligoarthritis, often in large joints of lower extremities (Figure 4). Enthesitis or bursitis can occur as well as other extra-articular features, common to other spondyloarthritides. Streptococcal sore throat (caused byA Group A beta-haemolytic streptococci) can be complicated by the development of acute rheumatic fever. Acute rheumatic fever can be suspected in the presence of two major manifestations, or one major and two minor manifestations, if the patient has evidence of preceding streptococcal infection, and other causes of acute arthritis have been ruled out. There are also patients with acute mono- or oligoarthritis preceded by group A streptococcalA pharyngitisA as the only manifestation without other features of rheumatic fever.
Finally, reactive arthritis is attributed in 10% of cases to be due to upper respiratory tract infection withA Chlamydia pneumoniae. Lyme disease (Lyme borreliosis) is a tick-borne infectious disease causing complex clinical symptoms.
TheA clinical features of Lyme diseaseA are usually divided between the duration of the disease (acute vs.
Erythema migrans, the hallmark of the primary infection, is observed in 70% of the patients.
Acute neuroborreliosis develops in about 15% of the patients within weeks-months after the primary infection. Human parvovirus B19 is a small non-enveloped DNA virus, which only replicates in erythrocyte precursors. The arthritis is acute, symmetric, often in metacarpophalangeal and proximal interphalangeal joints of hands.
The clinical picture of systemic lupus erythematosus and parvovirus infection can be very similar; furthermore, parvovirus antibodies can be produced by a patient with established systemic lupus erythematosus . Arthritis and arthralgia are uncommon in children and in adult male subjects, but occur in about 50% of adult females, soon after the onset of the rash. Alphaviruses belong to a group of arboviruses and share the common feature of transmission by arthropod vectors. The Sindbis virus induced diseases in Northern Europe typically occur in late summer or early fall, coincident with walking in the forest during mosquito time.
Patients infected withA HIVA (human immunodeficiency virus) infection have increased frequency of musculoskeletal complaints (14). Septic arthritis due to the usual infectious agents are not increased in HIV patients, but musculoskeletal infections caused by atypical mycobacteria are increased. Previously, HIV infected patients often developed severe psoriasis-like skin disease and also psoriatic arthritis.
The availability of HAART has made a great change in the prognosis of the patients infected with HIV.
Polyarticular arthritis or arthralgia, which affects mainly small joints of the fingers, may occur in about 20% of the patients withA acute hepatitis B virus infection. Gout, an inflammatory response to monosodium urate monohydrate crystals and pseudogout (chondrocalcinosis), an inflammatory response associated with calcium pyrophosphate crystal deposition are the major forms of crystal-related joint inflammation.
Acute gout develops within hours and is designated by intense pain, swelling and redness of the affected joint (Figure 7), and often by fever ascribed to spill-over of pro-inflammatory cytokines from the inflamed joint into the circulation. Pseudogout also presents in 90% of cases as monoarthritis, but unlike in gout, the knee is the most common affected joint, followed by the wrist, shoulder, ankle and elbow. In sarcoid arthritis, a non-caseating granulomatous inflammation affects the joint tissue, most commonly the ankles and the knee joints and less frequently other larger joints such as shoulders, hips, wrists, elbows or small joints of the hand and feet. Paraneoplastic joint inflammation presents usually as a polyarthritis, often asymmetric arthritis with predilection to joints of the lower limbs. The clinical features may be suggestive for the final diagnosis of a patient who presents with fever and acute arthritis (Figure10).
Patients with gonococcal arthritis can have elevated WBC in the blood, and elevated ESR and CRP.
The diagnosis of reactive arthritis relies, besides to the typical clinical picture, on demonstration of the triggering infection, such as isolation of the microbe or demonstration of elevated antibodies.
In about 60% of the patients with reactive arthritis, evidence of previous infection can be detected either by serology or by cultures from urogenital or stool samples.
Based on hospital series, the occurrence of HLA-B27 has been reported to be as much as 90% but is considerably lower or not elevated at all if patients with mild arthritis is examined.
Culture of the borrelia in skin biopsy and in plasma can be performed, but the culture is rarely successful from the synovial fluid.
The diagnosis of parvovirus infection is made by serology, where the presence of IgM class parvovirus antibodies refer to a recent infection within 3 months. The routineA laboratory diagnostics of rubellaA infection is based on the detection of antirubella antibodies in the serum. The diagnosis is based on demonstration of crystals, sodium urate crystals in gout and calcium pyrophosphate crystals in pseudogout, in synovial fluid samples using polarized microscopy. The diagnosis of acute sarcoid arthritis is based on typical clinical picture (marked periarticular swelling of ankles bilaterally and hilar lymphadenopathy), further supported if erythema nodosum is observed. The acute onset of seronegative asymmetric polyarthritis with markedly elevated inflammatory markers should raise the suspicion of cancer polyarthritis. The treatment includes arthrocenthesis with removal of any purulent material from the joint and institution of systemic antibiotic therapy before the results of the bacterial cultures are available. The drainage of the inflammatory debris is beneficial for the preservation of the joint function and limiting the joint destruction. Lyme borreliosisA is treated with antibiotics, the use of which is tailored to the clinical picture of the disease. Treatment is symptomatic, but acetosalicylic acid is to be avoided if there is a suspicion of a hemorrhagic disease. The treatment is following the lines of that for reactive arthritis in general, starting with NSAIDs.
If there are no contraindications for the use of antiviral therapy, this is logical to start.
The patients with chronic joint disease are at increased risk of developing bacterial arthritis. The primary prevention of acute rheumatic fever is based on adequate (10 days or over) antimicrobial treatment of tonsillopharyngitis caused by group A beta-haemolytic streptococcal infection. While it shares the general characteristics of all forms of septic arthritis [18,19], it also has several features specific to its site and diagnosis, and related to its course and prognosis.

In the absence of tenosynovitis or skin lesion, the clinical features of the gonococcal may mimic those of nongonococcal septic arthritis caused for instance byStaphylococcus aureus.
Later on, the presence of microbial cell wall structures, DNA and even RNA have been demonstrated in the joints of the patients with typical reactive arthritis. The primary focus of infection is through mucosal membrane, usually in the gut or in the urogenital tract (Table 4).
Of the other microbes causing urethritis, there is no consensus whether Neisseria gonorrhoea can trigger reactive arthritis. In hospital-based series, about 60-80% of the patients have HLA-B27, the presence of HLA-B27 is associated with a more severe arthritis and occurrence of extra-articular features, and it predicts a prolonged disease. They are invasive and cause primary infection of gastrointestinal mucosa (enteric pathogens) or urogenital mucosa (A Chlamydia trachomatisA ).
The viable organisms or bacterial antigens are disseminated to the joint, causing local inflammatory response in the joint. The role of HLA-B27 in this process has been discussed, and the favorite hypothesis is a cross-reaction between microbial structures and HLA-B27, or that HLA-B27 itself might be a target of immune response. They include eye symptoms (conjunctivitis,A acute anterior uveitis), various skin symptoms (Figure 6), and occasionally onycholysis in prolonged or chronic cases, resembling those seen in psoriasis. Indeed, migratory polyarthritis is one of the five major manifestations of rheumatic fever (Table 6), whose diagnostic criteria (the Jones criteria) have been updated in 1992 (5).
According to these criteria, a patient with streptococcal infection followed by arthritis as the only major manifestation, should have at least two other minor manifestations for the diagnosis. This so-called post streptococcal reactive arthritis usually develops within 14 days afterstreptococcal pharyngitis; fever and scarlatiniform rash are often present during the acute phase of pharyngitis, but are absent by the time the arthritis appears. The clinical picture is that typical of that of the other reactive arthritides, here usually preceded by upper respiratory tract infection.
About half of the patients develop also signs and symptoms of systemic infection (malaise, fatigue, headache, arthralgia, myalgia, low-grade fever, andA lymphadenopathy). It can manifest in the skin as chronic atrophic changes, occurring in European patients and caused byB. Transmission of infection occurs via respiratory route, through blood products and vertically from mother to fetus.
However, parvovirus infection is a very rare cause of the development or flare-up of systemic lupus erythematosus. Arthritis is usually symmetric polyarthritis, most commonly in the metacarpophalangeal and proximal interphalangeal joints of hands, followed by wrists, knees, ankles and elbows. Alphaviruses are spherical small RNA containing viruses with a potential to induce arthritis, fever, fatigue and rash.
In Northern Europe, milder forms of disease induced by alphaviruses belonging to the Sindbis group has described in several countries. The incubation time is short (2-10 days), after which the onset of arthritis is usually sudden. It is typically oligoarticular, predominantly in the lower extremities, and lat lasts less than 6 weeks. The use of highly active anti-retroviral therapy (HAART) is effective in the treatment of the HIV infection and also the associated psoriasis and arthritis. The presence of the cryoglobulins and the clinical associations speak in favor of the hepatitis C as the background cause of arthritis.
The joint symptoms last 2 to 3 weeks and gradually resolve when the patients starts to turn yellow. Of the initial attacks, about 90% are monoarticular and about 50% affect the first metatarsophalangeal joint.
Like in gout, the onset of the attack is rapid, the affected joint is tender, warm, red and swollen and functionally impaired, and the presence of fever is common. Although the joints are usually affected bilaterally, they may be affected asymmetrically in a consecutive manner.


It can be suspected in an elderly patient with acute asymmetric arthritis and markedly elevated ESR and CRP.
Although not specific for any of the underlying pathomechanisms, they may be helpful, together with patient’s history and family history of rheumatic disorder, in selecting diagnostic laboratory tests, imaging, and selecting initial therapy.
During the acute phase of enteric infections isolation is usually possible from the stools.
IgM and IgG class antibodies can persist in some patients for many years, even after therapy.
Borrelia DNA has been detected by PCR in skin biopsies, cerebrospinal fluid, synovial fluid, blood and urine. As most people have acquired parvovirus infection in the childhood, the presence of IgG class antibodies is common and in the absence of IgM class antibodies is not of diagnostic aid. The diagnoses of infections cause by HIV, hepatitis C virus, or hepatitis B virus are based on serology and PCR techniques.
Hyperuricaemia is a risk factor for the gout, and the risk increases along with the increase in urate levels. They provide useful information of the pre-existing condition of the joints, such as bone erosions associated with rheumatoid arthritis or bone cysts associated with chronic sarcoid arthritis.
The choice of the antibiotic is primarily empirical and based on the likelihood of the organism involved (Table 10). This can be performed as daily needle aspiration, arthroscopic debridement with lavage, open lavage or arthrotomy with synovectomy. Local glucocorticoid injections can be applied and are usually also of benefit in the patients with mono- or oligoarticular disease, as is usually the case.
In the more severe or prolonged disease, sulphasalazine is the recommended drug, but hydroxychloroquine can also be tried.
The risk factors include the presence of knee or hip prosthesis, rheumatoid arthritis, comorbidity (malignancy, diabetes mellitus) and age of 80 years or over.
At present, no vaccine exist against alphaviruses and prevention is based on using mosquito repellents, bed nets and appropriate clothing at endemic areas. Treatment of acute streptococcal pharyngitis and prevention of rheumatic fever: a statement for health professionals.
Antibiotic prophylaxis for haematogenous bacterial arthritis in patients with joint disease: a cost effectiveness analysis.
The full set of clinical symptoms and signs of acute arthritis comprises swelling representing joint effusion, limited joint motion, tenderness, increased warmth and redness of the skin.
In addition to fever, increased respiratory rate, increased heart rate and abnormalities in peripheral blood white blood cell (WBC) count and differential cell counts all denote the presence of systemic inflammation.
Indeed, infectious etiology should be suspected as long as the cause of acute joint inflammation is not known.
This is probably due to the asymptomatic genitourinary infection, which is more frequent in women and allows spreading of the infection.
Even knowing this, the term reactive arthritis defined as above, is useful to cover the clinical entity. In studies of defined outbreaks or in epidemiological surveys at population level, the picture is different. The invasiveness of the bacteria is not probably contributed by the genetic factors (HLA-B27), but there is abundance of evidence in favour of the hypothesis of an impaired elimination of the microbes in the infected host. A CD4+ T-cell response to the invading micro-organism drives the arthritic process, supported probably also by CD8+ T-cell response. About 30% of the patients have acute inflammatory low back pain, typically worse during night, radiating to buttocks. Contrary to the arthritis of acute rheumatic fever, which is migratory and responds rapidly to acetosalicylic acid, the arthritis in the post streptococcal reactive form is prolonged and running the course of typical reactive arthritis. Borrelia infection can also cause eye inflammation (conjunctivitisA and uveitis, most commonlyposterior uveitis). The most common manifestation of the infection isA rash, preceded about 6 days prior byA lymphadenopathy. The spectrum of clinical symptoms in association with alphavirus infections is wide, from severe haemorrhagic symptoms to paresthesias and glomerulonephritis (Table 9). In Finland, this mosquito-borne viral disease is called Pogosta disease, in Sweden Ockelbo disease, and in Russian Karelia it is called Karelia fever. The arthritis in Pogosta disease is often oligoarticular (ankle, knee, wrist, fingers, especially metacarpophalangeal joints). The musculoskeletal symptoms can be divided in 3 subgroups: those associated directly with the HI virus infection, those occurring more frequently in HIV positive individuals, at least partially associated with increased risk of infection, and those as a result of HIV treatment. The synovial fluid, if obtained for analysis, is non-inflammatory and sterile for bacteria. Mucocutaneous complications (keratodermia blenorrhagica and circinate balanitis) are common.
Diffuse myopathy, muscular pain, elevated muscle enzyme levels, even rhabdomyolysis, and avascular necrosis of bone have been reported with increasing frequency on patients treated with antiviral drugs.
After theA acute phase, 50%-70% of the patients developA chronic infection, which is a risk factor for future development of liver cirrhosis and hepatocellular carcinoma.
The cryoglobulins form immune complexes and could be responsible for arthritis at least in a part of the patients. Most of the attacks develop spontaneously and take slightly longer than gout to resolve, 1 to 3 weeks, if not treated. The affected joints show tenderness with effusions, limitation of movement and often prominent periarticular swellings.
It may precede the diagnosis of the malignancy in the lung or the breast and may resolve after resection of the carcinoma. Joint aspiration is positive in about 50% of the cases; bacterial cultures of the skin lesions are usually negative.
Ligase chain reaction and polymerase chain reaction are available for the detection of nucleic acid sequences specific forN. However, by the time arthritic complications appear, the patient may have already recovered from the gastroenteritis and the microbe is often no longer detectable, and the laboratory diagnosis is often dependent on the serodiagnosis. Positive serology alone without a history of a urogenital tract infection does not suffice to make a definite diagnosis ofChlamydia-induced reactive arthritis. If the clinical picture is not strongly favoring reactive arthritis, the post-test possibility of the use of HLA-B27 in the diagnosis is low. Other rheumatic conditions, such as Lyme arthritis, gout, rheumatoid arthritis, viral arthritides and osteoarthritis, should be excluded on the basis on clinical picture. A highly sensitive ELISA test should be used in screening, and the result confirmed by an immunoblot test. It is not a routine method, but can be used as an aid in the differential diagnosis of synovitis. The patients can be transiently seropositive for rheumatoid factor, anti-neutrophil cytoplasmic antibodies as well as have various auto-antibodies which can make differential diagnosis between parvovirus arthritis and other arthritides very complicated. Recent primary rubella, remote rubella infection, reinfection and persistent rubella IgM reactivity may be differentiated by measuring rubella-specific IgG avidity (4).
Although hyperuricaemia is prerequisite of, it is not sufficient for the development of gout because many hyperuricaemic subjects never develop gout. The laboratory markers of sarcoidosis (elevated serum ACE and lysozyme levels, hypercalcaemia and a€“calciuria) can be positive, but less often than in chronic systemic sarcoidosis. Acute sarcoid arthritis is frequently associated with bilateral hilar lymph node enlargement.
When the culture results are available, the antibiotics can be focused according to the sensitivity results.
There are no randomized studies that could show the superiority of any of these interventions. In the rare case of persistent rubella arthropathy, intravenous immunoglobulin therapy may be effective. SuccessfulA treatmentA of the infection can lead to recovery from the arthritis in the majority of the patients. The used of diuretics can also induce hyperuricaemia and gout, the indications should be reviewed and, if possible, the doses should be reduced of the drug should be changed. In a patient carrying one or more of the risk factors, the use antimicrobial prophylaxis, in terms of bacterial arthritis, seems to be indicated in patients with dermal infections, or infections of the urinary and respiratory tracts (8). In the secondary prevention, the duration of antimicrobial prophylaxis depends on several factors, such as the risk of exposure to streptococcal infections and the age of the patient (3).
Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease of the Council on Cardiovascular Disease in the Young, the American Heart Association. Arthralgia is distinct from arthritis and denotes pain of the joint without the other clinical signs of inflammation. Although joint inflammation is frequently associated with fever, inflammation confined to the joints does not necessarily elicit fever, or elevation of body temperature may be prevented by the use of nonsteroidal anti-inflammatory drugs (NSAIDs), immunosuppressive drugs, such as glucocorticoids and TNF (tumor necrosis factor)-blocking agents, or by age.
Other risk factors for gonococcal arthritis are pregnancy, menses, multiple sexual partners, low socio-economic status, intravenous drug use, complement deficiency, human immunodeficiency virus infection and systemic lupus erythematosus.
Obviously, in some patients the clinical features may progress from a dermatitis-tenosynovitis syndrome to monoarticular joint inflammation. Also bacteria belonging to the normal gut flora, such asA Escherichia coli, have occasionally been connected with reactive arthritis. The disease is usually mild, oligo- or polyarticular, and there is only a slight or no increase in the frequency of the HLA-B27 antigen (10). In patients with reactive arthritis, bacterial antigens seem to disseminate in the body, and chlamydia, yersinia, salmonella andA shigellaA antigens have been detected in the synovial fluid or in synovial tissue.
There is an imbalance in the production of proinflammatory cytokines by peripheral blood mononuclear cells during acute arthritis (low TNF production). The patients are usually young adults, with a mean age of about 30-40 years; in children the disease is uncommon and usually associated with gastroenteritis.
Acute rheumatic fever is nowadays a rare disease in the developed countries, but is still a major concern in the developing countries. The arthritis is usually mono- or oligoarticular, affecting large joints (knee, ankle, elbows).
These adverse events have been linked with various therapies, especially protease inhibitors. In addition to causing hepatitis, hepatitis C virus is lymphotropic and has been associated with the induction of various autoantibodies and immunologic entities. The more common is polyarthritis, often mimicking rheumatoid arthritis, which involves small joints (metacarpophalangeal joints, wrists, ankles). Thus, the presence of normal liver enzymes in laboratory screening does not rule out the possibility of hepatitis C virus infection. Although gout may affect any joint, in general, the lower limbs are affected more often than the upper limbs. Extra-articular manifestations of sarcoidosis are common and include the presence of erythema nodosum nodules usually in the lower limbs (Figure 8) and bilateral hilarA lymphadenopathyA in chest radiology (Figure 9). Unlike paraneoplastic arthritis, the metastatic joint inflammation is usually monoarticular reaction in large joints, such as the hip and knees.
Laboratory markers of systemic inflammation (increased WBC count, ESR and CRP) have only a limited diagnostic value due to their insensitivity.
Unfortunately there are no international standards for the tests, and the techniques vary greatly (6). The detection of borrelia by PCR is highly specific, but the sensitivity in the synovial fluid is max 85%. Parvoviral B19 DNA has been detected in synovial fluid samples in some patients with early synovitis or with chronic rheumatoid arthritis.
Patients with chronic sarcoid arthritis can also have positive serology for rheumatoid factor. New radiographic bone changes become evident only a couple of weeks after the onset of joint infection (Figure 11,A Figure 12).
The duration of the intravenous therapy can be 10-14 days, often followed by oral antibiotics.
In practice, if a joint is easily accessible by needle arthrocenthesis, this approach can be used provided that the clinical effect is observed. Uncomplicated enteritis preceding reactive arthritis is not an indication for treatment with antimicrobials.


Skin lesions in reactive arthritis and psoriatic arthritis, another form of arthritis observed in HIV infected patients, responds also to etretinate (14). Recurrent gouty arthritis is an indication to therapy with allopurinol; it should be started first after the acute attack is resolved. In the case of HLA-B27-associate reactive arthritis, it is possible, although no controlled studies exist, that early treatment of the triggering infection with antibiotics might prevent the development of arthritis.
Special Writing Group of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease of the Council on Cardiovascular Disease in the Young of the American Heart Association. Infectious arthritis denotes joint inflammation triggered by a microbe capable of multiplying within the joint tissue. Indeed, elderly patients with systemic inflammation associated with sepsis not so infrequently present with normal body temperature.
Gram negative organisms are more common in older patients and immunocompromised patients than in younger patients.
The diagnosis is based on the clinical picture supplemented with an evidence of gonococcal infection.
Yersinia DNA and even RNA as well as chlamydial DNA and RNA have been detected by sensitive techniques in the joints, but also in some asymptomatic control persons. Patients with chlamydia reactive arthritis have also elevated number IL-10- and TGF-I?-secreting cells in the synovial membrane compared with samples from rheumatoid arthritis patients. Male and female patients have similar risk for the development of reactive arthritis induced by gastrointestinal infection, while reactive arthritis triggered byChlamydia trachomatisis more frequently diagnosed in male patients.
During a later follow-up, some of the patients have had signs of chronic rheumatic heart disease, making the diagnosis of the acute phase questionable. The risk of infection is variable in geographically different areas, depending on the density of infected ticks, their feeding habits and annual hosts.
The rash, present in the majority of the patients, appears 3-4 days after the onset of illness, and disappears after a few days. The arthritis is usually self-limiting, and can be treated with non-steroidal anti-inflammatory drugs (NSAIDs). Reactive arthritis is observed in 5-10% and psoriatic arthritis in 1-6% and undifferentiated spondyloarthritis in 3-11 % of the patients. At the same time, there has been a great shift in the diagnoses compared with historical data. Hepatitis C infection has been associated with vasculitis, either associated with cryoglobulinaemia or a polyarteritis nodosa-like vasculitis.
In more than two thirds of the patients there are risk factors for acquisition of hepatitis C in the history, such as blood transfusion, use of injected drugs, or tattooing.
The hepatitis C virus itself has been found in the synovial fluid cells, taken as an indicator of direct infection. Without treatment, mild attacks resolve within a couple of days, severe attacks usually within a week.
This form of acute sarcoid arthritis, also called LA¶fgren's syndrome, is common in Scandinavian countries.
Cultures are preferred because of the microbial sensitivity pattern can also be determined. Therefore, a high suspicion forChlamydiaat the background is relevant for the diagnosis of reactive arthritis with tests to detect ofChlamydia trachomatisin the urogenital tract. Musculoskeletal radiology of acute sarcoid arthritis is normal, contrary to that in chronic sarcoid arthritis, where in addition to unspecific signs of inflammation (periarticular swelling, less frequently periarticular osteoporosis), cysts in finger and toe bones can be occasionally seen. Magnetic resonance imaging (MRI) reveals changes before radiography, is useful in evaluation of the joint and its bony structures, and is superior to computed tomography in evaluation of soft-tissue changes. The total duration of treatment is depending on the infecting micro-organism, the other diagnosis and therapies, and on the initial response to the treatment. However, if a patient has a past history of reactive arthritis, the option for treatment of also uncomplicated enteritis may be clinically justified. The patient has to be referred to pulmonlogists examination for the extension of lung involvement.
During the ongoing arthritis, however, the introduction of antibiotics does not modify the course of the disease. Bacterial arthritis, called also purulent, suppurative, pyogenic orA septic arthritis, is a rheumatologic emergency.
Poststreptococcal reactive arthritis is not a single entity but a very heterogeneous group of diseases manifesting from acute rheumatic fever to a more like HLA-B27 associated reactive arthritis without other features of acute rheumatic fever. The distribution of clinical features are slightly different if patients from the North America or from Europe are compared (Table 7). It can manifest as chronic encephalitis, encephalomyelitis, peripheral neuropathy, even as cerebral vasculitis. In adults, its manifestations are more protean (Table 8), including symptoms such as aplastic anemia,thrombocytopeniaA and pancytopenia.
Vaccination can also induce similar arthritis in adult females, thought to be due to immune complexes (4).
Other systemic symptoms include fever, muscle pain, malaise, headache, nausea, and retro-orbital pain.
In the more severe arthritis, low-dose glucocorticoids, hydroxychloroquine or sulphasalazine can be used. There are differences in clinical features in the phenotypes of arthritides between African patients with AIDS and the Western patients, those in Western having more typically reactive arthritis. Although most patients have circulating rheumatoid factor, anti-CCP-antibodies are usually negative. Furthermore, the persistence of hepatitis C virus in the peripheral blood mononuclear cells could induce chronic antigenic stimulation, especially in the long-living B-cells, and thus induce imbalance in the immune system leading to chronic B-cell activation and immune-mediated disorders, including arthritis. A patient with acute sarcoid arthritis can also have fever and elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP); rheumatoid factor can also be positive. Radiography of the joint is usually normal, unless there is a chronic rheumatic condition (rheumatoid arthritis, osteoarthritis etc), but it is worth to study to exclude the possibility of underlyingA osteomyelitis.
Search forChlamydiain the first portion of the morning urine by ligase reaction seems to be the test-of-choice. Bone scintigraphy, performed for instance with technetium-99m-labeled diphosphonates, may not distinguish between aseptic arthritis, septic arthritis, and osteomyelitis (13). For spinal pain, drugs with high anti-inflammatory effect and long half life are preferred by the patient. There are single reports of the use of anti-TNF drugs safely without the induction of increased viral load or increases in serum aminotransferase levels.
There is no specific drug to suppress the crystals of calcium pyrophosphate to accumulate in the joints.
Reactive arthritis denotes sterile joint inflammation, which is preceded by an infection elsewhere in the body and is typified by the presence of bacterial structures (lipopolysaccharides, called also endotoxin, DNA), but no multiplying bacteria, within the joint space. It has spread into whole Europe, except for the most warm and dry areas in the south and the most cold areas in the north.
Clinical suspicion is strengthened by the history of preceding rash, which, however, can be absent. Symptoms common to all alphavirus infections include rhinorrhoea, sore throat, marked lethargy and backache. These induce systemic infection, and frequently infection of several joints or skeletal sites.A Cutaneous lesionsA (nodules, ulcers, draining sinus tracts) occur frequently. Infective joint complications are also frequently observed in the African AIDS patients, while AIDS is the leading cause of aseptic arthritis (60% of the cases). In the pathogenesis of arthritides, both direct spreading of the HI-virus to the joints, immune response of the host to the infection, and infection of the host with pathogens known to be capable to trigger reactive arthritis especially in HLA-B27 positive subjects (Chlamydia, salmonella, yersinia,A shigella, campylobacter) contribute to the development of arthritis. In addition, malignant complications (non-Hodgkin lymphoma and Kaposi’s sarcoma) have been more frequently observed, while reactive arthritis and psoriatic arthritis have been decreasing. Both the Th1 and Th2 cytokines are elevated in the sera of the patients, which can further propagate the inflammatory aberration and autoimmune phenomena. Particularly in the elderly, polyarthritic gout with low degree inflammatory reaction to urate crystals may be regarded as a type of osteoarthritis. Finally, imaging with leukocytes labeled with indium-111 (Figure 13) or technetium-99m do not reliably separate infectious arthritis from non-infectious arthritides, such as rheumatoid arthritis, gouty arthritis, and pseudogout. In the case of severe arthritis of large joints with progressive symptoms, the use of disease modifying antirheumatic drugs used in rheumatoid arthritis, can be considered. Causes of chondrocalcinosis should be searched (hyperparathyroidism, haemochromatosis) and treated accordingly.
Immune response to infection, such as hepatitis B virus infection, elicits circulating, complement-binding immune complexes, which may enter the joint and trigger immune complex arthritis. As to autoinflammatory syndromes, including Still’s disease, and prosthetic-joint-associated infections, we refer to recent comprehensive reviews (2,A 17). If no such history can be obtained, parvovirus antibodies are not indicated in the search for triggering infection e.g.
The arthritis is usually transient with migratory arthralgia in the small joints of hands, feet, wrists and ankles, often accompanied by generalized myalgia. These infections occur late in the course of HIV infection, as also fungal infections, which also can cause septic arthritis. Compared with rheumatoid arthritis, the arthritis in patients with hepatitis C virus infection, despite often being seropositive for rheumatoid factor, is more benign, not erosive, with fluctuating activity. The gout attacks can be precipitated by a variety of factors such as drugs which alter the circulating urate levels, dietary factors (wines, beer, fish skin, meat) and trauma including surgery.
If leucocyte labeled scan is positive, a three-phase bone scan with technetium-99m labeled diphosphonates can be used in the confirmation of osteomyelitis, where focal hyperperfusion, focal hyperemia, and focal bone uptake is observed (13) (Figure 14).
Sulphasalazine, when started during the first 3 months, can induce clinical remission more rapidly compared with placebo.
Masson, Paris, pp 128–1337.David-Chausse J, Dehais J, Boyer M, Darde M, Imbert Y (1981) Les infections articulaires chez l’adulte. The inflammatory reaction may be confined to the joint compartment, or it may be part of a systemic (generalized) inflammatory reaction going on in the body.
In about half of the patients the recovery from the arthritis can take more than 1 month, even for more than 12 months, but a complete recovery is the rule (9).
The arthritis is symmetrical and nonerosive, with predilection to large joints in the lower extremities. The less common form of arthritis is mono- or oligoarthritis, usually in larger joints (wrists, shoulders, ankles, knees) but without features of spondyloarthropathy. Finally, urate crystals may be considered as foreign bodies which render the joint susceptible to bacterial infections. Systemic inflammation derives from the activation of the innate immune mechanisms in the circulation and thereby throughout the body.
