A case report of monoarthritis in a COVID-19 patient and literature review: Simple actions for complex times

RATIONALE

COVID-19 presentation is multifaceted and up to 44% of patients affected by COVID-19 experience musculoskeletal complaints, mostly in the form of diffuse aspecific arthromyalgias. Nevertheless, only a few cases of arthritis following SARS-CoV2 infection are reported.

PATIENT CONCERNS

A 27-year-old man affected by nail psoriasis presented with monoarthritis 2 weeks after being diagnosed with COVID-19.

DIAGNOSES

Diagnostic work-up and differential diagnosis were made difficult by patient isolation, absence of lab tests, and his visit via telemedicine, even though signs of first metacarpophalangeal joint involvement were clear.

INTERVENTIONS

Due to the inefficacy of acetaminophen and nonsteroidal anti-inflammatory drugs, the patient was prescribed oral steroids with a rapid benefit.

OUTCOMES

The patient's response to oral steroid was prompt and maintained even after therapy tapering. Even so, a formal diagnosis was not possible due to a difficult diagnostic work-up and lack of a long-term follow-up.

LESSONS

Like many other viral diseases, SARS-CoV2 can play as a causative agent or as a trigger for inflammatory arthritis development in predisposed individuals.

[PCR-based detection of pathogens in clinical rheumatology]

In the differential diagnostics of autoimmune-mediated rheumatic diseases, rheumatologists often have to consider infections (e. g. Lyme arthritis) or reactive diseases (e. g. reactive arthritis after urogenital bacterial infections). Furthermore, infections with an atypical presentation or caused by atypical pathogens (opportunistic infections) can complicate the immunosuppressive therapy of autoimmune diseases. For this purpose not only conventional microbiological culture methods but also PCR-based methods are increasingly being applied for the direct detection of pathogens in clinical specimens. The aim of this overview is to present commonly used PCR methods in the clinical practice of rheumatology and to describe their benefits and limitations compared to culture-based detection methods.

Hand-Foot and Mouth Dısease and Reactıve Arthritis: An Unusual Paediatric Case

Reactive arthritis is defined as arthritis that occurs during or after an extraarticular infection. It is mostly difficult to determine the causative agent that causes inflammation in the joints. Initially, salmonella, shigella, chlamydiaand yersinia were considered to be pathogenic agents. But recently, in addition to demonstrated viral and bacterial agents, there are also other cases of reactive arthritis after vaccinations with Rubella and Influenza. Herein a 3-year old boy is reported with reactive arthritis of left knee that developed shortly after hand-foot and mouth disease. This report represents the first detailed description of a paediatric case in literature with reactive arthritis following hand-foot and mouth disease.

[SPECIES COMPOSITION OF INFECTIOUS FACTORS THAT CAUSE THE REACTIVE ARTHRITIS DEVELOPMENT AND THEIR EFFECT ON ARGINASE-NO-SYNTHASE REGULATORY SYSTEM OF PERIPHERAL BLOOD LYMPHOCYTES]

The own observations results of urogenital, gastrointestinal and nasopharyngeal infectious factors that cause the development of reactive arthritis (PeA) are being presented. The greatest contribution to the development of this disease make Chlamidia trachomatis (36%), Streptococcus haemolyticus (pyogenes) (19%) and hepatitis viruses B and C (10%). As a result of the research a number of kinetic parameters of arginase and NO-synthase reactions in peripheral blood lymphocytes of patients with reactive arthritis was identified. The authentic increase of arginase activity in 3.3 times and eNO-synthase activity decrease by 1,9 times in peripheral blood lymphocytes of patients with PeA, compared to practically healthy donors were determined. Increased activity of arginase and iNO-synthase of lymphocytes indicates changes in immune cells functional activity, which may be due to impaired metabolic and regulatory processes in these cells caused by a bacterial or viral infection.

Mannose binding lectin is required for alphavirus-induced arthritis/myositis

Mosquito-borne alphaviruses such as chikungunya virus and Ross River virus (RRV) are emerging pathogens capable of causing large-scale epidemics of virus-induced arthritis and myositis. The pathology of RRV-induced disease in both humans and mice is associated with induction of the host inflammatory response within the muscle and joints, and prior studies have demonstrated that the host complement system contributes to development of disease. In this study, we have used a mouse model of RRV-induced disease to identify and characterize which complement activation pathways mediate disease progression after infection, and we have identified the mannose binding lectin (MBL) pathway, but not the classical or alternative complement activation pathways, as essential for development of RRV-induced disease. MBL deposition was enhanced in RRV infected muscle tissue from wild type mice and RRV infected MBL deficient mice exhibited reduced disease, tissue damage, and complement deposition compared to wild-type mice. In contrast, mice deficient for key components of the classical or alternative complement activation pathways still developed severe RRV-induced disease. Further characterization of MBL deficient mice demonstrated that similar to C3^−/− mice, viral replication and inflammatory cell recruitment were equivalent to wild type animals, suggesting that RRV-mediated induction of complement dependent immune pathology is largely MBL dependent. Consistent with these findings, human patients diagnosed with RRV disease had elevated serum MBL levels compared to healthy controls, and MBL levels in the serum and synovial fluid correlated with severity of disease. These findings demonstrate a role for MBL in promoting RRV-induced disease in both mice and humans and suggest that the MBL pathway of complement activation may be an effective target for therapeutic intervention for humans suffering from RRV-induced arthritis and myositis.

Arthritogenic alphaviruses such as Ross River virus (RRV) and chikungunya virus are transmitted to humans by mosquitoes and cause epidemics of debilitating infectious arthritis and myositis in various areas around the world. Studies in humans and mice indicate that the host inflammatory response is critical for development of RRV-induced arthritis and myositis, and the host complement system, a component of the host inflammatory response, plays an essential role in the development of RRV-induced disease through activation of complement receptor 3 (CR3)-bearing inflammatory cells. Of the three main complement activation pathways, only the lectin pathway activated by mannose binding lectin (MBL) was essential for RRV-induced complement activation, tissue destruction, and disease. Furthermore, we found that levels of MBL were elevated in human patients suffering from RRV-induced polyarthritis and MBL levels correlated with disease severity. Taken together, our data implicates a role for MBL in mediating RRV-induced disease in both humans and mice, and suggests that therapeutic targeting of MBL may be an effective strategy for disease treatment in humans.

[Lamivudine treatment of a HBs antigen positive man with reactive arthritis]

A 46-year-old man who was HBs antigen positive since childhood had painful talocrural arthritis that was considered re-active to HBs antigen. Lamivudine treatment was started and HBV-DNA disappeared from the blood, and the joint swellings disappeared. HBe antibody disappeared after eight months. After one year and nine months lamivudine was discontinued, resulting in a flare of the hepatitis after 56 days: HBV-DNA rose to 40 million copies per ml and HBe antigen became positive. Lamivudine was reinstituted, resulting in normalization of ALAT and lowering of HBV-DNA under detection level.

Frequency of recent parvovirus infection in patients examined for acute reactive arthritis. A study with combinatorial parvovirus serodiagnostics

OBJECTIVE

To determine the causative role of human parvovirus B19 as a preceding infection in patients examined for acute reactive arthritis (ReA).

METHODS

Sixty adult patients with acute arthritis were screened for evidence of triggering infections. In all patients, cultures of stool specimens and of Chlamydia trachomatis in urethra/cervix, and/or bacterial serology were studied. The timing of primary infection of human parvovirus B19 was determined by measurement in serum of VP2-IgM, VP2-IgG, epitope-type specifity of VP2-IgG, and avidity of VP1-IgG.

RESULTS

Median time from onset of joint symptoms to the rheumatological consultation was five weeks (range 1-62). Of the 60 patients, 35 fulfilled the diagnostic criteria for ReA; in the remaining, the diagnosis was unspecified arthritis (UA). Thirty-six patients had antibodies for the B19 virus. Occurrence of these antibodies did not differ significantly between ReA and UA groups (P = 0.61). Of these 36 patients, 34 had a pre-existing immunity to the B19 virus. Of the two other patients, one had rash and self-limiting polyarthritis with serological evidence of B19 primary infection, and the other had arthritis of the lower extremities with serological evidence of a convalescence period after the B19 primary infection. The latter patient also had antibodies to Yersinia, with a clinical picture typical for ReA.

CONCLUSION

In patients examined for acute ReA, the frequency of recent B19 virus infection was 3.3% (2 out of 60). The diagnostic utility of the presented methodology, by using a single serum sample, was evident.

Infection and musculoskeletal conditions: Rheumatologic complications of HIV infection

The pandemic caused by the human immunodeficiency virus (HIV) has entered its second quarter-century, with 40 million people now affected worldwide - particularly in Africa, where the impact has been most devastating. A complex array of rheumatic disease manifestations has been described, including diseases specific to HIV infection such as HIV-associated arthritis and the diffuse infiltrative lymphocytosis syndrome; other conditions which occur prominently in HIV-positive individuals include vasculitis, reactive and psoriatic arthritis and HIV-associated polymyositis, opportunistic musculoskeletal infections, and finally disorders that were originally ameliorated by HIV infection, such as rheumatoid arthritis and lupus. Effective antiretroviral treatment ameliorates many of these disorders; however, the introduction of highly active antiretroviral treatment (HAART) has introduced a new spectrum of disorders and new challenges confronting the clinician, including osteonecrosis, rhabdomyolysis, and, with immune reconstitution, the appearance de novo of a variety of autoimmune disorders and phenomena.

Infection and musculoskeletal conditions: Viral causes of arthritis

Several viruses cause postinfectious arthritis. The disease is a typical manifestation of arthritogenic alphaviruses, rubella virus and human parvovirus B19. In addition, arthritis is not uncommon after infection by HIV, cytomegalovirus, hepatitis B virus, hepatitis C virus, or Epstein-Barr virus (EBV). Also prolonged arthritis may result from viral infections, particularly with alphaviruses and human parvovirus B19. Viruses such as EBV and B19 may have significant roles in initiating chronic arthropathies, which in some cases may be indistinguishable from rheumatoid arthritis.

Human immunodeficiency virus related reactive arthritis in Zambia

OBJECTIVE

To characterize the clinical, radiological, and diagnostic features of reactive arthritis (ReA) in indigenous Black Zambians with human immunodeficiency virus (HIV) infection.

METHODS

Consecutive patients attending an arthritis clinic over a 5-year period were studied prospectively. Those who satisfied diagnostic criteria for ReA were analyzed.

RESULTS

In total, 170 patients satisfied the ESSG criteria for ReA; 71 (45 men, 26 women) had one or more extraarticular manifestations; 30% had enteroreactive and 14% uroreactive disease. Only 59% of patients had the diagnostic features of ReA at presentation. The initial diagnosis was undifferentiated spondyloarthropathy (uSpa) in 20%, other ReA in 14%, and "arthritis alone" in 7%. Of 65 (42 men, 23 women) patients tested, 94% were HIV-positive (91% men, 100% women). In those with HIV, the arthritis was predominantly polyarticular, lower limb-predominant, and progressive; 58% of 33 with persistent disease had erosions of foot and/or hand joints (average disease duration, 24.4 mo); 6 of 10 showed early radiological spine or sacroiliac joint changes (average duration 47.7 mo). Anterior uveitis occurred in 33% of patients, while keratoderma blenorrhagicum and stomatitis occurred in 14.3% and 9.5%, respectively, of patients with enteroreactive ReA. Uroreactive ReA was more common in women. There were no significant differences in the clinical, diagnostic, or radiographic features between men and women or between those with or without a known preceding trigger.

CONCLUSION

HIV associated ReA in Black Zambians frequently follows an accelerated course with a strong tendency to relapse, develop early erosions and joint deformity, and become chronic. The clinical, diagnostic, and radiographic features are indistinguishable from those described in the conventional (HLA-B27 related) disease, although our HIV-positive patients have a high overall frequency of uveitis, keratoderma, and onycholysis.

Infections preceding early arthritis in southern Sweden: a prospective population-based study

OBJECTIVE

To detect evidence of infections preceding early arthritis in Southern Sweden and to compare the clinical outcome of remission during a 6-month followup for patients with and without signs of prior infection.

METHODS

Adult patients with arthritis of less than 3 months' duration were referred from primary health care centers to rheumatologists. All patients were systematically screened for infections caused by Salmonella typhimurium and Salmonella enteritidis, Yersinia enterocolitica, Campylobacter jejuni, Borrelia burgdorferi, Chlamydia trachomatis, Chlamydia pneumoniae, and parvovirus B19.

RESULTS

Seventy-one patients were included in this study. Twenty-seven (38%) patients had reactive arthritis (ReA), 17 (24%) undifferentiated arthritis, 15 (21%) rheumatoid arthritis (RA), 4 (6%) psoriatic arthritis, and the rest (11%) other diagnoses. Of all the patients, 45% had evidence of a recent infection preceding the arthritis, as indicated by laboratory tests and/or disease history. C. jejuni dominated the ReA group. The occurrence of recent C. trachomatis, B. burgdorferi, C. pneumoniae, and parvovirus B19 infections was low. Overall, 58% of the patients went into remission during the 6-month followup. Of the patients with a preceding infection, 69% went into remission as compared to 38% of the patients without a preceding infection (p = 0.011). Thirty-three percent of the patients with RA were in remission after 6 months.

CONCLUSION

In this population-based cohort, 45% of the patients presenting with a new-onset arthritis had had a prior infection. Campylobacter ReA dominated the ReA group. There were only a few cases preceded by infections by C. trachomatis, B. burgdorferi, C. pneumoniae, and parvovirus B19 infections. Remission during the first 6 months was especially frequent in the group of patients with a prior infection, but the remission rate was relatively high even for arthritis without prior infection.

Infliximab in the treatment of an HIV positive patient with Reiter's syndrome

Reiter's syndrome is an acute inflammatory arthritis with no standard treatment options for patients unresponsive to nonsteroidal antiinflammatory drugs (NSAID). In patients positive for human immunodeficiency virus (HIV), HIV-RNA levels have been correlated with elevated tumor necrosis factor-alpha (TNF-alpha) levels. We investigated the safety and activity of infliximab, an anti-TNF-alpha chimeric monoclonal antibody, in the treatment of an HIV positive patient with Reiter's refractory to NSAID therapy. A 41-year-old HIV positive man with Reiter's syndrome was treated with infliximab 300 mg intravenously at Weeks 0, 2, and 6 and then every 6 to 7 weeks thereafter. He presented with severe fatigue, pain, muscle wasting, synovitis of the elbows, wrists and knees, a scaly rash in the groin area, burning during urination, and severe onycholysis on all digits. Laboratory assessment revealed hemoglobin 7.8 g/dl, erythrocyte sedimentation rate (ESR) 152 mm/h, white blood cell count 5700 cells/mm3, and C-reactive protein (CRP) 65.7 mg/dl. HIV viral load on presentation was 1600 quantitative:ultrasensitive (Qn:US) copies/ml, decreased from a maximum of 428,000 Qn:US copies/ml at the start of antiretroviral therapy. After 6 months taking infliximab, all complaints resolved, nails regrew, and the rash cleared. CRP decreased to 0.8 mg/dl and ESR to 22 mm/h. During this 6 month period antiretroviral therapy remained unchanged, and the viral titer remained below 400 Qn:US copies/ml.

Unusual localisation of chronic arthropathy in lumbar facet joints after parvovirus B19 infection

Human parvovirus B19 infection may be responsible for acute and chronic arthropathy. We present the case of a woman, who developed a severe chronic parvovirus B19 infection with persistence of DNA parvovirus B19, which was detected in the serum by polymerase chain reaction (PCR). After intravenous immunoglobulin administration she noted a disappearance of the general symptoms and the virus became undetectable by PCR in the serum. However, 1 month later back pain appeared. Magnetic resonance imaging showed bilateral effusions of the apophyseal joints of the lumbar spine (L4-L5). Spine involvement is rarely described during acute or chronic parvovirus B19 infection. In this case it was not possible to determine whether the facet joint arthropathy was reactive or due to persistent articular infection, or induced by immunoglobulin therapy.

Human immunodeficiency virus associated spondyloarthropathy: pathogenic insights based on imaging findings and response to highly active antiretroviral treatment

The pathogenesis of human immunodeficiency virus (HIV) associated spondyloarthropathy (SpA) is poorly understood. In this case report a patient is described with severe HIV associated reactive arthritis, who on magnetic resonance imaging and sonographic imaging of inflamed knees had extensive polyenthesitis and adjacent osteitis. The arthritis deteriorated despite conventional antirheumatic treatment, but improved dramatically after highly active antiretroviral treatment, which was accompanied by a significant rise in CD4 T lymphocyte counts. The implications of the localisation of pathology and effect of treatment for pathogenic models of SpA and rheumatoid arthritis in the setting of HIV infection are discussed.

Rheumatic manifestations of HIV-AIDS

Infection by human immunodeficiency virus is characterized by a myriad of clinical manifestations affecting almost every organ system in the body. If untreated, it follows an inexorable course, leading to a profound state of immunosuppression and eventually death from opportunistic infection and/or development of lymphoproliferative malignancy and Kaposi's sarcoma. Rheumatic manifestations may develop at any time of the clinical spectrum, but usually are more often seen in late stages. A variety of disorders may be seen, particularly Reiter's syndrome and undifferentiated spondyloarthropathy. Most patients do well with conventional anti-inflammatory therapy, but some will require the use of immunosuppressive-cytotoxic therapy.

Pogosta disease: clinical observations during an outbreak in the province of North Karelia, Finland

OBJECTIVE

To characterize the clinical picture of Pogosta disease.

METHOD

The data of 73 patients who had had Pogosta disease in 1981 and who then had been seen by a local physician in North Karelia were analysed.

RESULTS

The main manifestations were fever (23%), rash (88%) and joint symptoms (93%). The joint symptoms in some patients lasted for several months and were severe enough to cause immobilization. The clinical picture was identical in those patients who had a definite serological diagnosis and those who did not have a detectable antibody response.

CONCLUSION

The symptoms of Sindbis virus-induced Pogosta discase consist of fever, rash and joint symptoms, whic may be severe and prolonged.

HIV infection-associated inflammatory musculoskeletal disorders

Inflammatory musculoskeletal complaints are relatively common during the course of HIV infection, although they tend to be more frequent during late stages. The clinical spectrum is varied, ranging from arthralgias to distinct rheumatic disorders, such as Reiter's syndrome and psoriatic arthritis. The therapeutic management often poses a challenge, although most patients respond to conventional first- and second-line anti-inflammatory medications.

Arthritis associated with HIV infection in Zimbabwe

OBJECTIVE

To document the clinical and immunogenetic features of arthritis associated with heterosexually acquired human immunodeficiency virus (HIV) infection.

METHODS

All patients were assessed by a rheumatologist and standard laboratory tests were performed.

RESULTS

There were 3 common clinical presentations. (1) Oligo/polyarticular arthritis (22 men, 4 women). HIV infection had not previously been diagnosed in 24 of these patients but persistent generalized lymphadenopathy (85%) and weight loss (42%) were present. Joints commonly involved were ankles (65%) and knees (54%), often with associated enthesitis (31%) and dactylitis (23%). Followup data in 18 patients showed that arthritis resolved completely in 9 patients (one subsequently recurred), improved by >50% in 5 patients, was unremitting in 3 patients, and recurred frequently in one patient. None of 7 patients tested were HLA-B27 or B7 positive. (2) Reiter's syndrome (RS) (21 men, 3 women; incomplete RS 18 patients,complete RS 6 patients). Lymphadenopathy was present in 19 patients (79%) and 4 patients were previously known to have HIV infection. Involvement of knees (80%) and ankles (58%) was common, as were enthesitis (29%) and dactylitis (13%). Followup data in 21 patients showed that 14 resolved (5 with recurrences), 2 improved by >50%, and 5 had continued arthritis. HLA-B27 was not found in 13 patients tested but a cross reacting antigen was found in 6 patients. (3) Symmetrical polyarthritis (4 men, 4 women). Symmetrical arthritis of the wrists (8 patients) and peripheral interphalangeal (PIP) and metacarpophalangeal (MCP) joints (7), as well as lymphadenopathy (5), nodules (4), rheumatoid factor (3), and erosive radiographic changes (one patient) were seen. (4) Miscellaneous. Other types of arthritis included 3 patients with psoriasis and arthritis and one patient each with Behcet's disease, Salmonella septic arthritis, and secondary syphilis.

CONCLUSION

Arthritis associated with HIV in this population is most commonly characterized by oligoarticular, asymmetrical, large joint arthritis, with or without features of Reiter's syndrome, and is not associated with HLA-B27.

Persistence of parvovirus B19 in synovial fluid and bone marrow

OBJECTIVES

To determine whether parvovirus B19 (B19) persists in rheumatoid arthritis (RA).

METHODS

Polymerase chain reaction (PCR) was used to detect parvovirus B19 genome in the synovial fluid cells or peripheral blood mononuclear cells from 61 patients with early RA; bone marrow from one patient was also studied. The synovium or synovial fluid cells from 28 patients with advanced RA, and synovial fluid cell samples from 18 patients with reactive arthritis (as controls) were studied. Two separate sets of primers and probe were used.

RESULTS

Parvovirus B19 specific gene sequences were detected in two patients with early arthritis fulfilling the criteria for RA.

CONCLUSION

Parvovirus B19 does not play a significant role in the aetiopathogenesis of RA. However, a few cases of a disease indistinguishable from RA may be triggered by parvovirus B19 infection.

Arthritis after mumps and measles vaccination

Measles, mumps, and rubella vaccine carries a risk of joint symptoms particularly in children under 5 years. A boy who presented with an inflamed knee after measles and mumps vaccination is reported; synovial fluid aspirated from the joint contained 4.3 x 10(9)/l leucocytes. It is thought that the mumps component is the aetiological cause of acute monoarthritis.

Infection and arthritis

Reactive arthritis is caused by an infection, and components of the triggering agent can be demonstrated at the site of inflammation. This fact has opened new views in studies regarding other rheumatic diseases, such as rheumatoid arthritis and ankylosing spondylitis. The possible role of infectious agents in their etiology and pathogenesis is being re-evaluated.
