The purpose of this study was to determine the characteristics of gouty arthritis in an urban Guatemalan population. We reviewed the medical records of 148 (145 males and 3 females) patients with a diagnosis of acute gouty attack seen at an urban rheumatology clinic in Guatemala City between 1982 and 1993. Mean age at diagnosis was 49 years (range 21-87), mean age of onset was 42 years, mean duration of disease 7.4 years, family history of gout 42 (28%), peak prevalence 5th decade 39 (26%). Seventy-one (48%) had monarticular, 49 (33%) oligoarticular, and 22 (15%) polyarticular attacks, respectively. Podagra was seen in 34 (23%) patients; however, 108 (73%) developed it at any moment of their life. Tophaceous gout was seen in 33 (22%). Mean serum urate concentrations (enzymatic method) were higher than 7.0 mg % in 90 (60%) patients. At follow-up, 44 (30%) patients never returned to our clinic, and a large majority of them [66 (45%)] were seen only during acute attacks. Associated disorders included hypertension (43%), obesity (27%), nephrolithiasis (16%), ischaemic heart disease (7%), renal insufficiency (2%), stroke (0.6%), and diabetes mellitus (0.6%), and two died due to sepsis; high alcoholic intake was found in 58 (39%) patients. In conclusion, our findings indicate that gout is not an unusual disorder in the Guatemalan population. It presents with the same characteristics as those reported in Caucasians, with the possible exception of a lower frequency of diabetes mellitus as an associated disorder.

Gout, although relatively rare in joint replacements, can present as an acute or chronic painful knee or hip arthroplasty. Gout and acute infection of a joint replacement can be difficult to differentiate, with the physical examination and laboratory study results frequently being similar. Both conditions can present with a rapid onset of joint pain, swelling, erythema, and constitutional symptoms, including fevers and malaise. Laboratory findings in both conditions often include an elevated leukocyte count, erythrocyte sedimentation rate, and C-reactive protein level. Negatively birefringent, needle-shaped crystals in the synovial fluid confirm the diagnosis of gout. The mistaken diagnosis of septic arthritis in a joint replacement with crystal-induced synovitis can lead to inappropriate open debridement or component removal. The current study includes a review of the literature and presents two cases of gout after total knee arthroplasty. These cases suggest that in situations of suspected sepsis without synovial fluid crystals, operative intervention is indicated with a presumed diagnosis of septic arthritis. The identification of chalky white or yellow deposits in the synovium or bone is highly suggestive of gout. The definitive diagnosis is made by polarized light histologic evaluation of these tissues. If these deposits are present in the absence of a positive preoperative culture, positive Gram stain for bacteria, or component loosening, component retention is indicated.

Bacterial infections with local inflammation or hematogenous spreading may occur after joint punctures and intra- or periarticular injections. The risk of severe infections increases in patients with diseases accompanied by low immunity, e.g., gout, alcoholism, rheumatoid arthritis, and diabetes mellitus. Cases of septic omarthritis after intra-articular injection with fatal outcome after delayed onset of therapy are known. In our clinic we treated a female patient who previously received an injection in the shoulder region in a different facility. On admission she was suffering from an abscess of the surrounding soft tissues, systemic inflammatory response syndrome (SIRS), and adult respiratory distress syndrome (ARDS). Because the clinical picture was recognized early, we were able to prevent severe progression with organ failure. Another female patient developed a postinjection bacterial acromioclavicular arthritis followed by septic inflammatory response syndrome (SIRS) and eventually multiple organ failure (MOF). With inconspicuous clinical findings in the initial shoulder examination the bacterial arthritis was detected as the cause of sepsis only after intensive investigations.

We report an unusual case of delayed death due to sepsis following closed blunt injury to the neck. The victim was a 71-year-old male with a clinical history of hypertension, diabetes and gout. He was found dead about three weeks after being assaulted. He had not consulted a hospital after the assault. Forensic autopsy demonstrated a large liquefied subcutaneous hematoma on the right side of the neck, peri- and thrombophlebitis of the right internal jugular vein. Otherwise, there was no evidence of trauma. Histological examination showed dermal vesicles in the skin covering the hematoma, accompanied by marked inflammatory cell infiltration phagocytosing gram-positive streptococci, subcutaneous edema, panphlebitis with partially organized thrombi and bacterial colonies, pulmonary edema and multiple pulmonary microthrombi involving bacterial aggregates. Postmortem serum C-reactive protein and neopterin levels were markedly elevated. These findings suggest sepsis as the cause of death, induced by infected internal jugular vein thrombophlebitis following blunt neck injury involving impaired skin barrier.

The role of the potent proinflammatory cytokine IL-1 in disease could clinically be investigated with the development of the IL-1 blocking agent anakinra (Kineret), a recombinant IL-1 receptor antagonist. It was first tested in patients with sepsis without much benefit but was later FDA approved for the treatment of patients with rheumatoid arthritis. More recently IL-1 blocking therapies are used successfully to treat a new group of immune-mediated inflammatory conditions, autoinflammatory diseases. These conditions include rare hereditary fever syndromes and pediatric and adult conditions of Still's disease. Recently the FDA approved two additional longer acting IL-1 blocking agents, for the treatment of cryopyrin-associated periodic syndromes (CAPS), an IL-1 dependent autoinflammatory syndrome. The study of autoinflammatory diseases revealed mechanisms of IL-1 mediated organ damage and provided concepts to a better understanding of the pathogenesis of more common diseases such as gout and Type 2 diabetes which show initial promising results with IL-1 blocking therapy.

Gout is a common disorder in adults that can lead to severe organ decline, disability and impaired quality of life due to the formation of periarticular tophi. We report a case of massive tophaceous gout in a 78-year-old man with a 16-year-long history of untreated disease. The patient gradually became disabled, his renal function deteriorated, and he finally died of sepsis. Our case demonstrates that chronic gout not only affects the joints, but is also associated with organ function decline and can, even nowadays, lead to death.

Colchicine is an active alkaloid that is commonly used for treatment of multiple diseases including gout, primary biliary cirrhosis and familial Mediterranean fever. Less commonly, it has been implicated in several fatal overdoses. Deaths from colchicine overdoses are usually due to multi-organ failure, whether directly from colchicine toxicity or due to ensuing sepsis. We report an extreme case of colchicine ingestion (1.38 mg/kg), which is the largest reported non-fatal colchicine overdose. The patient was a 47-year-old First Nations woman with a history of depression and no other comorbidities. Ingestion was intentional and initial presentation was within 2 h of ingestion, at which point she had normal clinical and laboratory parameters. Early implementation of a targeted therapeutic strategy directed at the predicted multi-organ failure which included aggressive use of a GI decontamination protocol, timely supportive measures including ventilator support and renal replacement therapy, as well as the utilization of broad-spectrum antibiotics and G-CSF for sepsis and leucopenia management, resulted in successful support and discharge of this patient off dialysis.

An outbreak of Chlamydophila psittaci occurred in an outdoor colony of 63 Magellanic penguins (Spheniscus magellanicus) at the San Francisco Zoo. Affected penguins presented with inappetence, lethargy, and light green urates. Hematologic and serum biochemical findings were consistent with chronic inflammation. Penguins did not respond to initial supportive and antimicrobial therapy, and 3 died. Necropsy results of the 3 birds revealed hepatomegaly and splenomegaly, and histologic lesions included necrotizing hepatitis, splenitis, and vasculitis. Chlamydophila psittaci infection was confirmed by results of Gimenez staining, immunohistochemistry, and tissue polymerase chain reaction assay. As additional birds continued to present with similar clinical signs, the entire colony of penguins was prophylactically treated with a 30-day minimum course of doxycycline, administered orally or intramuscularly or as a combination of both. Despite treatment, 9 additional penguins died during a 3-month period. Pathologic results from these birds revealed renal and visceral gout (n = 4), cardiac insufficiency (n = 2), sepsis from a suspected esophageal perforation (n = 2), and no gross lesions (n = 1). During the outbreak, 4 birds presented with seizures, 5 developed dermatitis, and nearly 90% of birds in the colony showed severe keratoconjunctivitis, believed to be related to drug therapy with doxycycline. We report the clinical and pathologic features of Chlamydophila psittaci infection in an outdoor colony of penguins and the associated challenges of treatment.

Recent studies point to a dual role for galectin-3 as both a circulating damage-associated molecular pattern and a cell membrane-associated pattern recognition receptor. The aim of this study was to assess the potential of circulating galectin-3 for discriminating between infections and non-infectious inflammatory disorders on the one hand, and between fungal and bacterial infections on the other. Galectin-3 and C-reactive protein (CRP) were measured in the plasma of 127 patients with either non-infectious inflammatory disorders (gout, autoinflammatory syndrome or pancreatitis) or an infection (viral lower respiratory tract infection, bacterial sepsis or candidaemia). Circulating galectin-3 concentrations were increased in patients with infections when compared with healthy volunteers or patients with non-infectious inflammatory diseases. At cut-off values with a specificity of 95%, the sensitivity of galectin-3 (>20.6 ng/ml) to discriminate between an infection and non-infectious inflammation was higher than that of CRP (>156 mg/l): 43% [95% confidence interval (CI) 33-53%] versus 27% (95% CI 19-37%), p = 0.03. After exclusion of patients with CRP <156 mg/l, galectin-3 concentration >20.6 ng/ml could identify 41 % (95% CI 29-53%) of the patients with an infection at the cost of one false-positive with non-infectious inflammation. Using this sequential approach, 57% of the patients with an infection could be selected. Galectin-3 concentrations were similar in patients with bacterial and Candida sepsis, while being lower in viral respiratory infections. Although galectin-3 does not discriminate between bacterial and Candida sepsis, the sequential use of CRP and galectin-3 in distinguishing infectious diseases from non-infectious inflammation may be superior to CRP alone.
