Brucellosis in a patient diagnosed with Coronavirus Disease 2019 (COVID-19).

Brucellosis is a common zoonotic infection. Brucellosis typically presents with fever, weakness, night sweats, and arthralgias. Symptoms associated with Coronavirus Disease 2019 (COVID-19) and infection with Brucella spp. are similar to one another, which may lead to delayed diagnosis of the latter condition. There are no previous reports of brucellosis in a patient previously diagnosed with COVID-19. We present here the case of a 20-year-old male who we diagnosed with brucellosis after joint pains and fever that persisted after resolution of COVID-19.

Relationship between the Gut Microbiome and Osteoarthritis Pain: Review of the Literature.

BACKGROUND: Osteoarthritis (OA) is the most common form of chronic pain in Europe (34%), representing a great economic and social cost to society. There are studies that suggest an intestine-brain-articulation axis and hint at the existence of low-grade intestinal inflammation in OA, which would be related to an alteration of the microbiota and to the impairment of the epithelial barrier, with leakage of the microbial components. PURPOSE: The purpose of this study was to review the association between gut microbiome and pain in the OA population through a review of the literature. METHODS: A literature search was conducted to identify all available studies on the association between the gut microbiome and pain in the OA population, with no publication date limit until September 2020 and no language limit, in the MEDLINE, CINAHL, Web of Science and Cochrane Central Register of Controlled Trials databases. RESULTS: Only three of 2084 studies detected and analyzed by performing the proposed searches in the detailed databases, were finally selected for this review, of which one was with and two were without intervention. These studies only weakly support a relationship between the gut microbiome and OA, specifically a correlation between certain taxa or microbial products and the inflammatory landscape and severity of OA symptoms, including knee pain. Conclusions: Despite encouraging results, this review highlights the paucity of high-quality studies addressing the potential role of the gut microbiome in OA-related pain, along with the disparity of the techniques used so far, making it impossible to draw firm conclusions on the topic.

A Rare Case Report of Tuberculous Infection in a Previously Neglected Dysplastic Hip of a Young Woman.

A 14-year-old girl presented with an insidious onset of left hip pain, limp, and intermittent fever for a 3-month duration. Patient had a history of toe walking since childhood which continued into adolescence. On radiographic investigations, she was found to have a dysplastic hip with fluid collection around the hip which was surgically drained. The microbiological investigations proved the presence of Mycobacterium tuberculosis (TB). Accordingly, she was started on anti-TB chemotherapy as per drug sensitivity. TB infection in a previously neglected dysplastic hip is not reported as per our knowledge and poses unique diagnostic and management difficulties.

Intestinal microbiome composition and its relation to joint pain and inflammation.

Macrophage-mediated inflammation is thought to have a causal role in osteoarthritis-related pain and severity, and has been suggested to be triggered by endotoxins produced by the gastrointestinal microbiome. Here we investigate the relationship between joint pain and the gastrointestinal microbiome composition, and osteoarthritis-related knee pain in the Rotterdam Study; a large population based cohort study. We show that abundance of Streptococcus species is associated with increased knee pain, which we validate by absolute quantification of Streptococcus species. In addition, we replicate these results in 867 Caucasian adults of the Lifelines-DEEP study. Finally we show evidence that this association is driven by local inflammation in the knee joint. Our results indicate the microbiome is a possible therapeutic target for osteoarthritis-related knee pain.

[Multi-Faceted Symptoms with Joint Pain, Exanthema and Eye Involvement]. / Facettenreiche Symptomatik mit Gelenkschmerzen, Exanthem und Augenbeteiligung.

HISTORY AND ADMISSION FINDINGS: In this case series, we describe 4 patients who presented to a rheumatologic clinic with very different complains however were ultimately diagnosed with the same underlying disease. The wide spectrum of symptoms included generalized maculopapular exanthema, arthralgia, myalgia and vision problems. One patient received anti-TNF therapy for ankylosing spondylitis and recurrent uveitis. On exam, joint swelling and skin changes were found. INVESTIGATION: All patients were found to have an elevated Treponema pallidum antibody titer and a positive of the rapid plasma reagin test. DIAGNOSIS: Patients were diagnosed with syphilis. TREATMENT AND COURSE: The first three patients received an intramuscular injection of 2.4 million benzabine penicillin G. The fourth patient was treated with penicillin 6 million IV 4 times a day for more than 14 days, due to immunosuppression CONCLUSION: In the presence of non-specific and often rather diffuse symptoms, with which patients in rheumatology often present, a non-primary rheumatological, e. g. infectious genesis, also needs to be considered. Due to the increasing incidence of syphilis in Germany in recent years special attention needs to be paid to this disease in rheumatological care.

Postoperative Lyme Arthritis in the Orthopaedic Patient.

CONTEXT: Lyme disease is the most common tick-borne illness in North America and Europe, and Lyme arthritis is a frequent late-stage manifestation in the United States. However, Lyme arthritis has rarely been reported as a postoperative complication. EVIDENCE ACQUISITION: The PubMed database was queried through June 2018, and restricted to the English language, in search of relevant articles. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 3. RESULTS: A total of 5 cases of Lyme arthritis as a postoperative complication have been reported in the literature. CONCLUSION: These cases highlight the importance for providers practicing in Lyme-endemic regions to keep such an infection in mind when evaluating postoperative joint pain and swelling. We propose herein an algorithm for the workup of potential postoperative Lyme arthritis. STRENGTH OF RECOMMENDATION TAXONOMY (SORT): C.

Comparison of Clinical Course and Treatment Outcome for Patients With Early Disseminated or Early Localized Lyme Borreliosis.

Importance: Multiple erythema migrans (MEM) has been suggested as a risk factor for unfavorable antibiotic treatment outcome compared with solitary erythema migrans (EM). However, no direct comparison of early Lyme borreliosis manifested as MEM with solitary EM has been undertaken. Objective: To investigate the potential differences in clinical course and treatment outcome between MEM and solitary EM. Design, Setting, and Participants: This prospective cohort study was conducted from June 1, 2010, to October 31, 2015, at the University Medical Center Ljubljana, Slovenia. Data were analyzed from June 1, 2017, to January 3, 2018. Of the 778 consecutive adult patients with early Lyme borreliosis evaluated, 200 patients with MEM and 403 patients with solitary EM were enrolled. Patients were asked to refer a family member or a friend of similar age (±5 years) without a history of Lyme borreliosis to serve as a control participant. Clinical course and posttreatment outcome of MEM were compared with those of solitary EM. Outcome was assessed at 14 days and at 2, 6, and 12 months after enrollment. At each visit, patients completed a written questionnaire about their symptoms; controls completed the same questionnaire. Nonspecific symptoms reported by patients and controls without a history of Lyme borreliosis were compared. Main Outcomes and Measures: The proportion of patients with incomplete response at 12 months after enrollment and the associated 2-sided 95% CI for the difference between MEM and solitary EM were estimated using the normal approximation with continuity correction. Results: A total of 200 patients with MEM and 403 patients with solitary EM were included. Among the 200 patients with MEM, 94 (47.0%) were males and 106 (53.0%) were females, with a median (interquartile range [IQR]) age of 47 (35-58) years. Among the 403 patients with solitary EM, 182 (45.2%) were males and 221 (54.8%) were females, with a median (IQR) age of 55 (42-62) years. Patients with MEM reported Lyme borreliosis-associated constitutional symptoms at enrollment more often than those with solitary EM (93 [46.5%]; 95% CI, 39.4-53.7 vs 96 [23.8%]; 95% CI, 19.7-28.3; P < .001). During the initial 6 months after treatment, the proportion of patients with incomplete response was higher in the MEM group than in the solitary EM group (14 days: 62 of 193 [32.1%] vs 72 of 391 [18.4%]; P < .001; 2 months: 38 of 193 [19.7%] vs 55 of 394 [14.0%]; P = .28; 6 months: 29 of 182 [15.9%] vs 31 of 359 [8.6%]; P = .02). However, at the 12-month visit, the outcome was comparable: 10 of 170 (5.9%) patients with MEM vs 20 of 308 (6.5%) patients with solitary EM showed incomplete response (-0.6; 95% CI, -5.5 to 4.3; P = .95). The frequency of nonspecific symptoms in patients was similar to that in controls. Conclusions and Relevance: The long-term outcome at 12 months after treatment was comparable, regardless of dissemination. Follow-up of at least 12 months after treatment is thus recommended for future studies that investigate post-Lyme borreliosis symptoms.

Usefulness of polymerase chain reaction for diagnosing Whipple's disease in rheumatology.

OBJECTIVES: To determine when Tropheryma whipplei polymerase chain reaction (PCR) is appropriate in patients evaluated for rheumatological symptoms. METHODS: In a retrospective observational study done in rheumatology units of five hospitals, we assessed the clinical and radiological signs that prompted T. whipplei PCR testing between 2010 and 2014, the proportion of patients diagnosed with Whipple's disease, the number of tests performed and the number of diagnoses according to the number of tests, the patterns of Whipple's disease, and the treatments used. Diagnostic ascertainment was based on 1- Presence of at least one suggestive clinical finding; 2- at least one positive PCR test, and 3- a response to antibiotic therapy described by the physician as dramatic, including normalization of C Reactive Protein. RESULTS: At least one PCR test was performed in each of 267 patients. Rheumatic signs were peripheral arthralgia (n = 239, 89%), peripheral arthritis (n = 173, 65%), and inflammatory back pain (n = 85, 32%). Whipple's disease was diagnosed in 13 patients (4.9%). The more frequently positive tests were saliva and stool. In the centres with no diagnoses of Whipple's disease, arthritis was less common and constitutional symptoms more common. The group with Whipple's disease had a higher proportion of males, older age, and greater frequency of arthritis. The annual incidence ranged across centres from 0 to 3.6/100000 inhabitants. CONCLUSION: Males aged 40-75 years with unexplained intermittent seronegative peripheral polyarthritis, including those without constitutional symptoms, should have T. whipplei PCR tests on saliva, stool and, if possible, joint fluid.

Coccidioides immitis septic knee arthritis.

A 78-year-old man developed right knee pain and swelling without other systemic symptoms. He had travelled frequently to the Central Valley of California. He was diagnosed with coccidioidomycosis based on joint fluid culture. Coccidioidal complement fixation antibody titres were extremely elevated. Arthroscopic debridement and fluconazole therapy did not lead to satisfactory improvement. Subsequent open debridement and change to itraconazole was followed by resolution of clinical signs of infection.

Tuberculous osteomyelitis of the wrist presenting as a monoarthritis syndrome.

Osteoarticular tuberculosis is the third most frequent location of tuberculosis after the lung and lymph nodes, accounting for approximately 10%-20% of all cases of extrapulmonary disease. Tuberculosis of the hand and wrist is the rarest osteoarticular location after the shoulder. The authors report the case of a 50-year-old woman without medical history who was diagnosed with isolated tuberculosis of the wrist presenting as monarthritis. The diagnosis was confirmed by histopathological and microbiological examination. Late stages of osteomyelitis are even rarer without any predisposing factors such as immunosuppression. This case underlines the importance of including tuberculosis in the differential diagnosis of monoarthritic syndromes to prevent delayed initiation of therapy and consequent complications and bone damage.
