Post-Lyme disease syndrome.

About 10% of patients with Lyme disease continue to experience musculoskeletal pain and cognitive dysfunction after recommended antibiotic treatment. This condition is called post-Lyme disease syndrome (PLDS) or post-treatment Lyme disease syndrome. These two terms are used interchangeably. The pathogenesis of PLDS has been controversial. The hypothesis that patients with PLDS may harbor hidden reservoirs of Borrelia burgdorferi after their initial antibiotic treatment is difficult to accept. The prospective, double-blind studies contradict this point of view. Also, recently published research applying xenodiagnosis to PLDS supports the opinion that PLDS most likely has an autoimmune background. Lengthy courses of antibiotics are not justified in patients with PLDS because of the lack of benefit, and they are fraught with hazards. Most patients with PLDS recover from persistent symptoms with time. However, it can take months before they feel completely well.

Selected acute phase proteins and interleukin-6 in systemic lupus erythematosus patients treated with low doses of quinagolide.

The relationship between endocrine regulation and immune system has recently become the subject of intense investigations. The objective of this study was to determine the extent of selected serum acute phase proteins (APP), IL-6 and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) involvement in systemic lupus erythematosus (SLE) patients during quinagolide therapy. A further aim of this study was to evaluate the relationships between the above mentioned parameters. In 25 SLE patients treated with a low dose of quinagolide (12.5-50 microg per day) and in 25 healthy persons who constituted the control group, serum concentration of C-creative protein (CRP), alpha-1-antitripsin (AAT), ceruloplasmin (CER), IL-6 and prolactin (PRL) were estimated at entry and in patients after 3 months of treatment. Moreover, SLEDAI score was calculated at entry and after 3 months of therapy with quinagolide. IL-6 and PRL levels were significantly higher in SLE group whereas the concentrations of CRP, AAT and CER were higher than in the controls, but without statistical significance. After 3 month therapy statistically significant decrease of serum level of IL-6 and PRL was revealed. Statistically significant lower serum concentration of CER was also obtained after 3 months of therapy whereas serum CRP and AAT concentration was lower compared with the mean pretreatment level but the results did not reach statistical significance. A raised SLEDAI score at entry was significantly reduced after 3 month therapy and positive correlation with PRL level in examined group of patients with SLE was noted at entry. The decreased serum concentration of IL-6, APP and SLEDAI score observed during applied therapy with small dose of quinagolide confirms the hypothesis that quinagolide may become a valuable and safe drug in the therapy of patients with mild SLE.

Abnormal portal vein waveform as an indicator of constrictive pericarditis - a case report.

We report a case of a 17-year-old patient referred to our outpatient Doppler Department due to clinical suspicion of liver cirrhosis. The patient presented with non-specific symptoms, such as malaise, pain in the right subcostal region, peripheral oedema. Until then, diagnostic imaging, including echocardiography was inconclusive. We performed the Doppler sonography of the portal system, which revealed normal diameter of the portal vein with abnormal, phasic and markedly pulsatile waveform. Hepatic veins distention with pathological reverse flow during systole was reported. Additionally, inferior vena cava was dilated and remained unchanged through the respiratory cycle. Basing on the above image a heart disease, which had not been taken into differential diagnosis before, was suggested. The following echocardiography, together with computed tomography, enabled a diagnosis of constrictive pericarditis. Successful pericardiotomy was performed. Such a complicated diagnostics happened to demonstrate an uncommon example of the use of portal vein waveform in making the proper cardiologic diagnosis.

Ultrasonography of the tongue in macroglossia - a case report.

This paper is an attempt to assess the usefulness of ultrasonography in the diagnosis of the enlargement of the tongue (macroglossia). The role of sonography in diagnosing local pathologies of the tongue, such as neoplasms, abscesses or granulomas, has been well-established for 20 years. Rarely is its usefulness considered with respect to diagnosing macroglossia with concomitant systemic diseases. The starting point of these considerations was the presented case of a 59-year-old patient with considerably enlarged tongue. The patient had difficulty speaking and ingesting meals. Moreover, he complained about swelling and pain in the carpal and proximal interphalangeal joints. Tongue ultrasound examination revealed blurred lingual structure with evident, irregular vascular pattern in the color Doppler. The obtained image helped to rule out local pathology of the tongue and directed our diagnostic considerations towards immunoglobulin-related diseases (deposition diseases). We believe that the presented ultrasound image of the tongue was helpful in the diagnostic process. Establishing the final, correct diagnosis was a particularly strenuous process. The suspicion of a deposition disease had been rejected during two previous stays in two hospitals. This was the consequence of a negative diagnostic test of staining tissue deposits with Congo red. An accurate diagnosis occurred to be a rare form of a deposition disease: lambda light chain disease with symptoms of amyloidosis. Such a diagnosis was based on a thorough hematological analysis. A high level of free lambda light chains in the serum was detected and the bone marrow biopsy showed 13% of plasma cells. The patient underwent chemotherapy.

Isolated axillary lymph node tuberculosis in ultrasonography. A case report.

We present a rare case of isolated axillary lymph node tuberculosis. A 66-year-old patient was admitted in order to perform the diagnostics of a painless tumor of the left armpit. Blood biochemistry tests and chest X-ray did not show any abnormalities. In the ultrasound examination a solid structure of the dimensions of 1.8×1 cm of irregular outline with adjacent hypoechogenic lymph nodes was visualized. The diagnosis of tuberculosis was based on histopathologic examination of the excised tumor. In the latter years an increase in extrapulmonary type of tuberculosis has been observed. Extrapulmonary tuberculosis may appear in practically each organ, nevertheless it affects pleura most often. Lymph node tuberculosis is the second, when it comes to the prevalence rate, type of extrapulmonary tuberculosis. In the majority of cases of lymph node tuberculosis it affects superficial lymph nodes. In the ultrasound examination a packet of pathological, enlarged and hypoechogenic lymph nodes is stated. In 1/3 of cases the central part of the nodes is hyperechogenic which indicates its caseation necrosis. Lymph nodes have a tendency to be matted and they have blurred outline. We observed this type of lymph node image in the presented patient. This image may be a diagnostic hint. Nevertheless, in the differentiation diagnostics one should take many other disease entities into consideration, inter alia: sarcoidosis, lymphomas, fungal infections, neoplastic metastases; the latter ones have an image most similar to tuberculosis lymph nodes. Tuberculosis ought to be considered in differential diagnosis of atypical masses.

Anti-inflammatory and monocyte-suppressing effects of simvastatin in patients with impaired fasting glucose.

The aim of our study was to compare the effect of simvastatin on systemic inflammation and monocyte secretory function between individuals with impaired fasting glucose (IFG) and patients with isolated hypercholesterolaemia. The study included 25 patients with IFG and 23 patients with hypercholesterolaemia. The lipid profile, fasting and 2-hr post-glucose load plasma glucose levels, homeostatic model assessment (HOMA) ratio, glycated haemoglobin, plasma high-sensitivity C-reactive protein (hsCRP) levels and monocyte release of TNF-α, interleukin-1ß, interleukin-6 and MCP-1 were assessed at baseline, and after 30 and 90 days of simvastatin treatment (20 mg/daily). Compared to monocytes of the control patients (22 age-, sex- and weight-matched patients without lipid and glucose metabolism abnormalities), monocytes of the patients with hypercholesterolaemia and patients with IFG released greater amounts of all studied cytokines and exhibited higher plasma levels of hsCRP, with no difference between the two groups of patients. Although in both the patients with hypercholesterolaemia and the patients with IFG simvastatin treatment improved lipid profile, it exhibited no effect on glucose metabolism markers. The drug markedly reduced plasma hsCRP and monocyte secretion of TNF-α, interleukin-1ß, interleukin-6 and MCP-1 in a lipid- and glucose-independent manner. Our results indicate that low-grade systemic inflammation and monocyte secretory function are disturbed to a similar degree in the patients with isolated hypercholesterolaemia and in the patients with IFG. They also show that simvastatin is an effective anti-inflammatory drug in patients with isolated early glucose metabolism abnormalities.
