[2022 Update of the Austrian Society for Rheumatology and Rehabilitation nutrition and lifestyle recommendations for patients with gout and hyperuricemia]. / Empfehlungen der Österreichischen Gesellschaft für Rheumatologie und Rehabilitation zu Ernährung und Lebensstil bei Gicht und Hyperurikämie ­ Update 2022.

BACKGROUND: Gout is the most frequent inflammatory joint disease in the western world and has a proven genetic background. Additionally, lifestyle factors, such as increasing life expectation and standard of living, sufficient or excess nutrition and a growing prevalence of obesity in the population as well as e.g. alcohol consumption, contribute to the rising incidence of hyperuricemia and gout. Apart from an adequate medication, medical consultation on nutrition and lifestyle is an essential part of the management of gout patients, who have a high risk of internal comorbidities. OBJECTIVE: In 2015 the Austrian Society for Rheumatology and Rehabilitation (ÖGR) working group for osteoarthritis and crystal arthropathies published nutrition and lifestyle recommendations for patients with gout and hyperuricemia. Since then, a multitude of studies have been published addressing this topic, which necessitated an update. METHODS: First, the authors performed a hierarchical literature search to screen for the literature published since 2015. Considering references given in the first publication, the relevant literature was selected and the recommendations from 2015 were either kept as published, reformulated or recreated. Finally, the evidence level and the level of agreement for each recommendation were added by the authors. RESULTS: Based on this process, 10 recommendations were generated instead of the initial 9. As in the original publication, a graphical presentation with symbols was constructed to complement the written text. CONCLUSION: The ÖGR recommendations on nutrition and lifestyle for patients with gout and hyperuricemia were updated in accordance with the most recent relevant literature. These are supposed to serve as information and education material for patients and updated information for physicians.

[Austrian nutrition and lifestyle recommendations for gout and hyperuricemia]. / Österreichische Ernährungs- und Lebensstilempfehlungen bei Gicht und Hyperurikämie.

BACKGROUND: Gout is the most common inflammatory arthropathy in the Western world. This is mainly due to the high socioeconomic status, sufficient even superfluous nutrition, overweight and alcohol consumption. Despite adequate medication, information and advice on nutrition and lifestyle are one of the cornerstones in the management of these patients. OBJECTIVE: The aim was to provide recommendations on nutrition and lifestyle in cases of gout and hyperuricemia by a group of rheumatologists, based on a review of the most recent literature. MATERIALS AND METHODS: The study group for osteoarthritis and crystal arthropathies of the Austrian Society for Rheumatology and Rehabilitation (ÖGR) carried out a literature search on this topic. The selected papers were listed according to the level of evidence. RESULTS: Based on this literature search nine recommendations were generated and modified via a Delphi approach: four red "don'ts" concerning nutrition and beverages to be avoided, three green "do's" concerning favorable food as well as two blue general lifestyle recommendations. The format of the recommendations is a two-page leaflet with the list of recommendations, level of evidence, strength of recommendation and literature citations on the front page and a colored icon presentation of food and beverages in a circle, matching the colors of the written recommendations, on the reverse. CONCLUSION: For the first time in Austria, nine recommendations on nutrition, beverages and lifestyle for patients with gout and hyperuricemia were defined for everyday practice, as education material for patients and updated information for physicians.

Decreased insulin requirement in relation to GFR in nephropathic Type 1 and insulin-treated Type 2 diabetic patients.

AIMS: In the presence of impaired renal function, patients require less insulin mainly because insulin clearance is prolonged. The aim of this study was to evaluate the insulin requirement related to glomerular filtration rate (GFR) in nephropathic Type 1 and Type 2 diabetic patients. METHODS: In a retrospective study we compared insulin requirement in 20 nephropathic Type 1 diabetic patients and 20 insulin-treated Type 2 diabetic patients from the onset of overt nephropathy until the final stage of renal disease. All patients had proteinuria > 0.5 g/24 h and creatinine clearance >/= 80 ml/min per 1.73 m2 at baseline. Creatinine clearance, urinary protein excretion, glycated haemoglobin and the required insulin doses were determined 3- to 6-monthly, basal C-peptide was measured at the beginning and the end of the observation period. The required insulin doses were evaluated at creatinine clearance rates of 80, 60, 40, 20 and 10 ml/min per 1.73 m2 (or at the initiation of dialysis treatment). RESULTS: The insulin requirement of patients with Type 1 diabetes was reduced from 0.72 +/- 0.16 IU/kg per day at a creatinine clearance rate of 80 ml/min, to 0.45 +/- 0.13 IU/kg per day at a creatinine clearance rate of 10 ml/min (decrement of 38%, P < 0.001). The insulin dose required by Type 2 diabetic patients was reduced from 0.68 +/- 0.28 IU/kg per day at a creatinine clearance rate of 80 ml/min to 0.33 +/- 0.19 IU/kg per day at a clearance rate of 10 ml/min (decrement 51%, P < 0.001). The fall in GFR, urinary protein excretion and glycated haemoglobin levels was similar in the two groups. In patients with Type 2 diabetes, C-peptide levels at the beginning and the end of renal function impairment were 2.2 (0.4-7.3) vs. 2.7 (0.1-4.9) ng/ml (NS). The reduction in insulin requirement was approximately the same in patients with an initial C-peptide level < 1.0 and in those >/= 1.0 ng/ml (decrement 57% vs. 46%). CONCLUSIONS: The reduction in insulin requirement in renal insufficiency is similar in Type 1 and insulin-treated Type 2 diabetic patients. In subjects with Type 2 diabetes, the residual insulin secretion has no impact on the reduction in insulin requirement dependent on the GFR.

[Malacoplakia: a possible complication of poorly controlled diabetes mellitus?]. / Malakoplakie--eine mögliche Komplikation bei Diabetes mellitus mit schlechter Stoffwechsellage?

HISTORY AND ADMISSION FINDINGS: A 47-year-old woman with poorly controlled diabetes mellitus (HbA1C 9.2%, fasting blood glucose > 200 mg/dl) had complained of moderately severe stabbing pain in the left abdomen. On admission there were no abnormal findings on abdominal palpation. INVESTIGATIONS: Abdominal ultrasound and computed tomography (CT) revealed a partly solid partly cystic well-circumscribed space-occupying lesion, about 15 cm in diameter, in the left abdomen, extending from the lower third of the kidney into the pelvis. DIAGNOSIS, TREATMENT AND COURSE: Biopsy of the lesion showed chronic granulating inflammation with foamy histiocytes (Hansemann macrophages) as characteristic substrate of extensive malakoplakia. Despite the size of the lesion it was not excised but long-term treatment with ciprofloxacin undertaken. At the same time, the diabetes was carefully controlled with ordinary insulin. Ten months later there was no longer any evidence of the lesion by ultrasound and CT. CONCLUSIONS: Even extensive malakoplakia can be successfully treated with ciprofloxacin. Poorly controlled diabetes together with a weak immune status (CD4/CD8 < or = 1) may have favoured the occurrence of malakoplakia.

[Cerebrolysin in treatment of painful diabetic neuropathy]. / Cerebrolysin in der Behandlung der schmerzhaften diabetischen Neuropathie.

Cerebrolysin is a peptide solution with free amino acids and biologically active peptides showing neurotrophic efficiency. In a placebo-controlled longitudinal study we investigated the effect of that drug for treatment of painful diabetic neuropathy in 20 type-II diabetic patients (9 women, 11 men, mean age 63 +/- 9 years, duration of diabetes 14 +/- 7 years). Patients received daily a cerebrolysin-infusion (20 ml in 500 ml Ringer) over a period of 10 days. In an age- and diabetes-duration matched placebo group of 10 type-II diabetic patients (7 women, 3 men, age 66 +/- 9 years, duration of diabetes 12 +/- 5 years) vitamin B infusion was administered (5 ml vitamin B complex in 500 ml Ringer) during 10 days. We compared a five-item symptom score scale (FIS) for pain, dysesthesia, paresthesia, nightly exacerbation, and sleep disturbances (grade 0 to 3) and a graphic visual analogue rating scale (VAS) for recording the magnitude of the pains (scale 0 to 100 mm) at the beginning and the end of the infusion therapy as well as 6 weeks later. Cerebrolysin was associated with a significant decrease in total FIS score from 8.7 +/- 1.9 at the start of therapy to 5.1 +/- 2.2 after 6 weeks (p < 0.001), and to a reduction of the VAS score from 4.2 +/- 0.8 to 2.8 +/- 0.9 (p < 0.001) during the same period of observation. In contrast in the placebo group the total FIS score decreased only from 7.9 +/- 1.2 at the beginning to 6.6 +/- 1.1 (p < 0.05) 6 weeks later and the VAS score from 4.5 +/- 0.6 to 4.0 +/- 0.5 (NS). Thus cerebrolysin led to a significant subjective improvement of painful diabetic neuropathy in type-II diabetic patients at least for a period of 6 weeks.
