Serum Procalcitonin as a Useful Serologic Marker for Differential Diagnosis between Acute Gouty Attack and Bacterial Infection

PURPOSE: Patients with gout are similar to those with bacterial infection in terms of the nature of inflammation. Herein we compared the differences in procalcitonin (PCT) levels between these two inflammatory conditions and evaluated the ability of serum PCT to function as a clinical marker for differential diagnosis between acute gouty attack and bacterial infection. MATERIALS AND METHODS: Serum samples were obtained from 67 patients with acute gouty arthritis and 90 age-matched patients with bacterial infection. Serum PCT levels were measured with an enzyme-linked fluorescent assay. RESULTS: Serum PCT levels in patients with acute gouty arthritis were significantly lower than those in patients with bacterial infection (0.096±0.105 ng/mL vs. 4.94±13.763 ng/mL, p=0.001). However, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels showed no significant differences between the two groups. To assess the ability of PCT to discriminate between acute gouty arthritis and bacterial infection, the areas under the curves (AUCs) of serum PCT, uric acid, and CRP were 0.857 [95% confidence interval (CI), 0.798-0.917, p<0.001], 0.808 (95% CI, 0.738-0.878, p<0.001), and 0.638 (95% CI, 0.544-0.731, p=0.005), respectively. There were no significant differences in ESR and white blood cell counts between these two conditions. With a cut-off value of 0.095 ng/mL, the sums of sensitivity and specificity of PCT were the highest (81.0% and 80.6%, respectively). CONCLUSION: Serum PCT levels were significantly lower in patients with acute gouty attack than in patients with bacterial infection. Thus, serum PCT can be used as a useful serologic marker to differentiate between acute gouty arthritis and bacterial infections.

Guía dietética para pacientes con hiperuricemia y gota agar / Dietary guide for patients with hyperuricaemia and drop agar

Gota proviene del latin Gutta es un término acuñado en el siglo V que significa exceso o derrame de flema por exceso de vino, comida y sexo. Llamada "Rey de las enfermedades yenfermedad de reyes" fue uno de los primeros desordenes reumáticos en ser reconocidos como entidad clínic a. Es la artritis por deposito de microcri s tales más común debida a desequilibrio en el metabolismo de las purinas que conlleva a hiperuricemia y el depósito de cristales de urato monosódico, caracterizada por ser de inicio monoarticular, que a fecta con mayor frecuencia la primera articulación metatarso de pie y que progresa en su forma crónica a poliarticular, asociada a destrucción progresiva y a la formación de tofos, falla renal y enfermedad cardiovascular. Predomina sexo masculino, su pr evalencia se calcula de 0.08% a nivel mundial, aumentando la frecuencia de sus ataques con el alto contenido de carnes, mariscos, cervezas y bebidas espirituosas. El objetivo de la presente revisión bibliográfica es proporcionar una guía dietética para lo s médicos enfatizando y destacando su contenido de purinas en alimentos de uso cotidiano en la población guatemalteca, para obtener un mejor control de la artritis gotosa y disminuir la frecuencia de sus ataques ...(AU)

Gota comes from Latin Gutta is a term coined in the fifth century that means excess or spill of phlegm for excess wine, food and sex. Called "King of diseases and disease of kings" was one of the first rheumatic disorders to be recognized as a clinical entity. Arthritis is the most common microcritical deposit due to imbalance in the metabolism of purines that leads to hyperuricemia and the deposition of monosodium urate crystals, characterized by monoarticular initiation, which most often occurs with the first metatarsal joint. standing up and progressing in its form chronic to polyarticular, associated with progressive destruction and the formation of tophi, renal failure and cardiovascular disease. Male sex predominates, its pr evance is estimated at 0.08% worldwide, increasing the frequency of its attacks with the high content of meats, seafood, beers and spirits. The aim of this bibliographical review is to provide a dietary guide for physicians emphasizing and highlighting their content of purines in foods of daily use in the Guatemalan population, to obtain a better control of gouty arthritis and to reduce the frequency of their attacks. ..

Existe uma relação entre a artrite gotosa e as mutações genéticas da febre familiar do Mediterrâneo? / Is there a relationship between gouty arthritis and Mediterranean fever gene mutations?

RESUMOObjetivoA artrite gostosa e a febre familiar do Mediterrâneo (FFM) compartilham algumas características clínicas e patológicas, como ser classificada como uma doença autoimune inflamatória, ter associação com o inflamassoma, manifestar artrite intermitente de curta duração e boa resposta a tratamentos com colchicina e anti-interleucina-1. Como o gene da febre familiar do Mediterrâneo (MEFV) é o fator causador da FFM, este estudo teve como objetivo investigar a prevalência de mutações do gene MEFV e seu efeito sobre as manifestações da doença em pacientes turcos com artrite gotosa.MétodosForam incluídos no estudo 97 pacientes com diagnóstico de artrite gotosa primária (93 M e 4 F; 54 [37-84] anos) e 100 controles saudáveis (94 M e 6 F; 57 [37-86] anos). Todos os indivíduos foram submetidos à análise do genótipo à procura de variações no MEFV. Também foi registrado o número de crises de gota, o uso de diuréticos e a história de nefrolitíase e presença de tofos.ResultadosA frequência de portadores de mutações no MEFV em pacientes e controles foi de 22,7% (n = 22) e 24% (n = 24), respectivamente. A comparação entre os pacientes e os controles não produziu diferença estatisticamente significativa em termos de frequência de portadores de mutações no MEFV (p = 0,87). As frequências alélicas de mutações no MEFV nos pacientes foram de 11,9% (n = 23) e 14% (n = 28) nos controles (p = 0,55). A presença de variantes do MEFV não mostrou qualquer associação com as características clínicas da artrite gotosa. A análise por subgrupos de pacientes revelou que aqueles com artrite gotosa com mutações tinham frequências semelhantes de tofo, história de nefrolitíase e podogra em comparação com os indivíduos sem mutações (p > 0,05).ConclusõesAs mutações no gene MEFV não exercem um papel relevante em pacientes turcos com artrite gotosa.

ABSTRACTObjectiveGouty arthritis and familial Mediterranean fever share some clinical and pathological features such as being classified as auto-inflammatory disease, association with inflammasome, short-lived intermittent arthritis, and good response to colchicine and anti-interleukin-1 treatments. As Mediterranean fever gene is the causative factor of familial Mediterranean fever, we aimed to investigate the prevalence of Mediterranean fever gene mutations and their effect on disease manifestations in Turkish gouty arthritis patients.MethodsNinety-seven patients diagnosed with primary gouty arthritis (93 M and 4 F, 54 [37–84] years) and 100 healthy controls (94 M and 6 F, 57 [37–86] years) were included in the study. All subjects were genotyped for the Mediterranean fever gene variations. Number of gout attacks, diuretic use, history of nephrolithiasis and presence of tophus were also recorded.ResultsThe carriage rate of Mediterranean fever mutations for patients and controls was 22.7% (n = 22) and 24% (n = 24), respectively. The comparison of the patient and control groups yielded no significant difference in terms of the Mediterranean fever mutations’ carriage rate (p = 0.87). The allelic frequencies of the Mediterranean fever mutations in patients were 11.9% (n = 23) and 14% (n = 28) in controls (p = 0.55). The presence of Mediterranean fever variants did not show any association with clinical features of gouty arthritis. The subgroup analysis of patients revealed that gouty arthritis patients with mutations had similar frequencies of tophus, history of nephrolithiasis and podagra compared to the ones without mutations (p > 0.05).ConclusionsThis study does not provide support for a major role of Mediterranean fever mutations in Turkish gouty arthritis patients.

Application of a Novel Diagnostic Rule in the Differential Diagnosis between Acute Gouty Arthritis and Septic Arthritis

Septic arthritis and gout are major diseases that should be suspected in patients with acute monoarthritis. These two diseases are clinically similar and often indistinguishable without the help of synovial fluid analysis. Recently, a novel diagnostic rule for gout without synovial fluid analysis was developed and showed relevant performances. This study aimed to determine whether this diagnostic rule could perform well in distinguishing gout from septic arthritis. The diagnostic rule comprises 7 clinical and laboratory variables, each of which is given a specified score. The probability of gout is classified into 3 groups according to the sum of the scores: high (> or = 8), intermediate (> 4 to < 8) and low probability (< or = 4). In this retrospective study, we applied this diagnostic rule to 136 patients who presented as acute monoarthritis and were subsequently diagnosed as acute gout (n = 82) and septic arthritis (n = 54) based on synovial fluid analysis. The mean sum of scores of acute gout patients was significantly higher than that of those with septic arthritis (8.6 +/- 0.2 vs. 3.6 +/- 0.32, P < 0.001). Patients with acute gout had significantly more 'high', and less 'low' probabilities compared to those with septic arthritis (Eta[eta]: 0.776). The prevalence of acute gouty arthritis, as confirmed by the presence of monosodium crystal, was 95.5% (61/64), 57.5% (19/33), and 5.1% (2/39) in high, intermediate and low probability group, respectively. The recently introduced diagnostic rule properly discriminates acute gout from septic arthritis. It may help physicians diagnose gout in cases difficult to be differentiated from septic arthritis.

Clinical factors and treatment outcomes associated with failure in the detection of urate crystal in patients with acute gouty arthritis

BACKGROUND/AIMS: To investigate the rate of detection of monosodium urate (MSU) crystals in the synovial fluid (SF) of patients with acute gouty arthritis and factors associated with false-negative results. METHODS: A total of 179 patients with acute gouty arthritis who had undergone SF crystal examination were identified from the data warehouse of two university hospitals. Clinical and laboratory data were obtained from the medical records. RESULTS: The overall rate of detection of MSU crystals was 78.8%. In univariate analyses, the only significant differences between the variables of crystal-negative and crystal-positive patients were a lower C-reactive protein level (p = 0.040) and fewer patients undergoing emergent surgery in the crystal-positive group (p = 4.5 x 10(-6)). In logistic regression analyses, MSU crystal-negative results were significantly associated with the interval from arthritis onset to crystal examination (p = 0.042), and this was the most significant risk factor for arthroscopic surgery (p = 2.1 x 10(-4)). Seventeen patients who underwent arthroscopic surgery had a significantly longer hospital stay (p = 0.007) and a significant delay in gout treatment (p = 8.74 x 10(-5)). The distribution of crystal-negative patients differed significantly between the SF samples that were evaluated by both the laboratory medicine and the rheumatology departments (p = 1.2 x 10(-14)), and the kappa value was 0.108. CONCLUSIONS: Although several clinical features were associated with detection failure, SF MSU crystal identification was critically dependent on the observer. Considering the impact on the treatment outcomes, implementation of a quality control program is essential.

Partial HPRT deficiency (Kelley-Seegmiller syndrome).

Hypoxanthine-guanine phosphoribosyl transferase (HPRT) deficiency is an X-linked defect of purine metabolism. Clinical manifestations are usually related to the degree of enzyme deficiency; complete HPRT deficiency (Lesh-Nyhan Syndrome) presenting with severe neurological or renal symptoms, or partial HPRT deficiency (Kelley-Seegmiller syndrome) manifesting as a gout-urolithiasis syndrome. We report a case of partial HPRT deficiency presenting as chronic tophaceous gout, mental retardation, nephrolithiasis and family history suggestive of X-linked inheritance, for its rarity.

A clinical study of crystal-proven gouty arthritis in a university hospital.

The clinical features of 567 patients with crystal proven gout (489 males, 78 females) seen in a University Hospital in northern Thailand was reviewed. The mean age at onset and mean duration of disease was 60.0 +/- 11.7 years and 5.2 + 4.8 years, respectively. Recurrent attacks accounted for 94 per cent. The knee and ankle were the 2 most common joints affected during the first attack and each one was seen in 55.6 per cent of cases. During a recurrent attack, the ankle, knee and first metatarsophalangeal joint were the 3 most common joints affected and were seen in 94.5 per cent, 81.2 per cent and 80.2 per cent of cases, respectively. Thirty-six per cent of the patients had tophi. Hypertension, hyperlipidemia, diabetes mellitus and ischemic heart disease were commonly associated diseases. Thirty-five per cent had renal calculi, and fifty-four per cent had renal insufficiency. Of 59 patients who tested with normal renal function, twelve per cent were hyperexcretor. The clinical features of gout seen in the university hospital in northern Thailand were similar to those reported in Bangkok, but with a higher incidence of tophaceous gout, renal failure and renal calculi.

Down's syndrome with coexistent gout in 2 patients: Is the association under reported or is the prevalence actually increasing?

This report describes 2 patients diagnosed with Down's syndrome and who developed acute gouty arthritis. While hyperuricemia in gout is a well-known abnormality, association of gout with Down's syndrome has not been widely discussed. With increasing life expectancy in this syndrome, it is likely that more such cases will occur. For early diagnosis and proper management clinicians must be aware of this association
