[Remission of steroid-resistant Stills disease treated with anakinra, evidenced by FDG-PET/CT examination: case report]. / Remise steroid-rezistentní Stillovy nemoci pri lécbe anakinrou dokumentovaná FDG-PET/CT vysetrením: kazuistika.

After elimination of infectious causes, neoplastic causes and the systemic autoimmune disease of connective tissue, a patient with high fevers over 39 °C was diagnosed with Stills disease. High doses of prednisone led to resolution of symptoms, however after reducing the doses of prednisone to 15 mg, high fevers over 39 °C returned, as well as joint pains. The high doses of prednisone led to decompensation of diabetes mellitus even with 4 daily insulin dosages. Therefore it was proceeded to regular subcutaneous administration of anakinra once a day. Anakinra enabled the reduction of prednisone to as much as the currently administered 2.5 mg a day, but it has not so far allowed for removing glucocorticoids from the treatment completely. Activity of the disease is shown by the findings within the FDG-PET/CT examination. At the time of maximum activity of the disease there was distinct lymphadenopathy with pathological accumulation of FDG visible as well as increased accumulation of FDG in the hematopoietic bone marrow. As the disease activity decreased, the size of nodules regressed and FDG accumulation in both the lymphatic nodes and bone marrow declined. FDG-PET/CT is a suitable method for monitoring the activity of Stills disease.Key words: anakinra - Adult-onset Stills disease.

[Schnitzlers SyndromeDifferential diagnostics, an overview of therapeutic options and description of 5 cases treated with anakinra]. / Schnitzlerové syndromDiferenciální diagnostika, prehled lécebných mozností a popis 5 prípadu lécených anakinrou.

Schnitzlers syndrome is an acquired auto-inflammatory disease of still unclear origin. The Strasbourg criteria were adopted (non-infectious fever, chronic urticaria, changes in the bone structure, leukocytosis and higher values of inflammatory markers - CRP and presence of monoclonal immunoglobulin mostly of type IgM, very rarely of IgG) to establish this diagnosis. The first-choice therapy for this disease is the blocking of interleukin-1 effects. In practice, the interleukin-1 receptor antagonist, anakinra, is the most commonly used. Currently reports also appear of the use of other medicines blocking the effect of interleukin-1, namely canakinumab and rilonacept. We have been treating 5 patients with anakinra (108, 72, 33, 32 and 1 months) on a long-term basis. In all the patients, we commenced administration of anakinra in a dose of 100 mg once a day. As a result of 100 mg being administered once a day, all symptoms went away completely in 4 patients, while they receded by about 75 % in 1 patient, without disappearing completely. This patient needs an increased dose of 2 ampoules per day on the days of spontaneously intensified medical ailments. After one year of treatment it turned out for one of the four patients whose symptoms had completely disappeared when administered the 100mg daily dose, that he only needed the respective dose of anakinra at 48-hour intervals. However this patient does not tolerate further extension of the intervals between dose administrations. We have not recorded any adverse effects of anakinra in the course of the treatment, and no decline in the efficiency of anakinra has been observed: it acts as effectively now as it did at the beginning of the treatment. The text discusses the differential diagnostics of the Schnitzler syndrome.Key words: anakinra - auto-inflammatory diseases - canakinumab - fever of unknown origin - FUO - interleukin 1 - cryopyrin-associated autoinflammatory syndrome (CAPS) - monoclonal gammopathy - rilonacept - Schnitzlers Syndrome - Adult Stills disease.

[Hypercalcemia, symptoms, differential diagnostics and treatment, or importance of calcium investigation]. / Hyperkalcemie, príznaky, diferenciální diagnostika a lécba aneb dulezitost vysetrování kalcia.

UNLABELLED: The concentration of calcium is carefully maintained under physiological conditions with parathormone, calcitonin and 1,25-dihydroxyvitamin D at appropriate levels. There are multiple causes that may bring about increased concentrations of calcium which exceed physiological values. Increased production of parathormone in parathyroid glands is only one of the possible causes. Malignant diseases are a very frequent cause of hypercalcemia, due to their creating mediators which stimulate osteoclasts and thereby osteolysis. A less frequent cause is represented by granulomatous processes, a typical example of which is sarcoidosis, whose cells increasingly (independently of parathormone) hydroxylate 25-hydroxyvitamin D to 1,25-dihydroxyvitamin D. However there are also hereditary forms of hypercalcemia. One of the causes of the hereditary form of hypercalcemia is mutations of the calcium sensing receptor. In order to locate the adenoma of parathyroid glands, essential apart from sonographic imaging is scintigraphy 99mTc-methoxyisobutylisonitrile (MIBI) and even more exact is PET-CT examination with a radio-pharmaceutical 18F-fluorocholine. PET-CT examinations are beneficial with regard to detecting a malignant cause of hypercalcemia in until then undetected malignancy or an undetected granulomatous process. The essential treatment procedures for malignant hypercalcemia include appropriate hydratation of ionic solutions without calcium, administering of bisphosphonates or denosumab. The text describes in detail the symptoms of hypercalcemia and diagnostics of causes of hypercalcemia. KEY WORDS: bisphosphonates - cinacalcet - denosumab - granulomatous diseases - hereditary hypercalcemia - hypercalcemia - hypercalciuria - hyperparathyreosis - calcimimetics - calcitonin - multiple myeloma - malignant hypercalcemia - parathormone - sarcoidosis - 1,25-dihydroxyvitamin D.

[Treatment of 14 cases of Castlemans disease: the experience of one centre and an overview of literature]. / Lécba 14 prípadu Castlemanovy nemoci: zkusenosti jednoho centra a prehled literatury.

Castlemans disease is the term for reactive lymphocytary and plasmocytary proliferation which occurs in the unicentric (localized) form, usually without systemic symptoms, or in the generalized/multicentric form, typically with systemic symptoms (www.vzacne-diagnozy.cz). Over the past 25 years we diagnosed, treated and followed 14 histologically proven cases of Castlemans diseases. Seven patients had the localised form of the disease. In 5 of 7 cases the pathological lesion was located intrathoracically or intraabdominally and in only 2 cases it was on the surface of the body. No clinical symptoms were present in any of the patients with the unicentric form of the disease and surgical treatment led to the total removing of the disease in all of them. As opposed to that, all 7 patients with the multicentric form of Castlemans disease experienced febrile or subfebrile temperatures. Three of the 7 patients complained of severe troubling night sweats. Clinical expressions of vasculitis which was the cause of stroke, were present in 1 of 7 patients. Osteosclerotic changes on the skeleton were detected in 1 patient, who also suffered from fluid retention likely associated with this disease. Polyclonal propagation of immunoglobulins, predominantly immunoglobulin IgG type, was present in 5 of 7 patients with the multicentric form. In one case there was one complete molecule of monoclonal imunoglobuline present and in one case loose light chains κ were increased More than 1 sampling of material for histological examination of enlarged lymph nodes were needed in 6 of 7 patients for diagnosing the multicentric form of the disease. It has turned out beneficial with respect to diagnosing the disease to carry out surgical removal and histological examination of the nodes which accumulated the most fluorodeoxyglucose within PET-CT examination. The text describes experience of the treatment. In recent years the basis for the treatment has been the monoclonal antibody antiCD20 rituximab, or thalidomide and lenalidomide, or possibly their combination. The new medicine for these patients is interleukin-6 antibody called siltuximab (Sylvant), of which we have no own experience so far. Five of our seven patients with the multicentric form received treatment, 1 patient refused treatment and in one patient the signs of the disease activity are not expressed to such extent that would require treatment. The therapy containing rituximab reached complete remission in 2 patients and the therapy containing thalidomide and lenalidomide achieved the complete remission of the disease in 3 patients. In one of the above described cases the disease did not respond to the initial treatment with rituximab and remission was reached by thalidomide and lenalidomide and in one case the disease did not respond to the initial treatment with thalidomide and complete remission was reached with rituximab. Following the treatment, no patient with the multicentric form of Castlemans disease has had a relapse until now.

[The patient complains of spinal pain or fatigue and weakness. How do I recognize whether their cause is spondylarthrosis, the patients age or multiple myeloma?]. / Pacient si stezuje na bolesti v páteri nebo na únavu a slabost. Jak rozeznám, zda je prícinou spondylartróza, vek nemocného anebo mnohocetný myelom?

Multiple myeloma has varied manifestations which resemble common patient complaints and that is why this disease is typically not diagnosed until it reaches an advanced stage. Spinal pains can be an expression of deformative and discogenous changes, but also a symptom of multiple myeloma. Pains in the long bones may result from the pain radiating from an arthrotic joint, but also from a large myelomatic osteolytic lesion which makes the bone prone to a spontaneous fracture. Pathological weariness may have many causes, multiple myeloma being one of them. Anemia may have a large number of causes and multiple myeloma is one of them. Raised creatinine levels and renal failure can also be due to many causes and again, multiple myeloma is one of them. Weakened immunity and frequent infections can also have many causes, among them multiple myeloma. Confusion and sleepiness may be due to psychiatric diagnosis, but also may result from hypercalcemia associated with multiple myeloma. The following text which is designed for non-hematology physicians therefore describes in detail the symptoms of multiple myeloma and diagnostic steps leading to establishing the diagnosis and it only briefly outlines the treatment related information. You can also visit www.myeloma.cz for details. This text aims to summarize the symptoms of multiple myeloma for physicians not specializing in hematology in order to facilitate earlier diagnosing of the disease.

[Changes in the prognosis and treatment of Waldenström macroglobulinemia. Literature overview and own experience]. / Zmeny v prognóze a v lécbe Waldenströmovy makroglobulinemie: prehled literatury a vlastní zkusenosti.

Waldenström macroglobulinemia is defined by the presence of monoclonal immunoglobulin IgM type (M-IgM) and evidence of lymphoplasmacytic bone marrow infiltration. The disease has an indolent course, the treatment is only initiated when the disease has begun to damage its carrier. The following symptoms are regarded as proven indications for initiating therapy: B symptoms, symptomatic lymphadenopathy, splenomegaly, anemia with hemoglobin below 100 g / l or thrombocytopenia < 100 × 10(9)/l, caused by lymphoplasmacytic bone marrow infiltration. Frequent indications for initiating treatment include clinical evidence of hyperviscosity or cryoglobulinemia. M-IgM tends to have a character of autoantibody reaching up to 50 %, which may harm the organism, and therefore any proven damage to the organism by an autoimmune activity of M-IgM is also an indication for treatment. The text includes an overview of rare and very rare types of damage to the organism by M-IgM autoimmune activity. A combination of rituximab, cyclophosphamide and dexamethasone (RCD) is recommended for the initial treatment, possibly extended to R-CHOP regimen (rituximab, cyclophosphamide, vincristine, doxorubicin and prednisone). In our cohort of 43 patients the therapy involving a combination of R-CHOP achieved 3 (8.1 %) complete remissions and 31 (83.8 %) partial remissions. The remission in 75 % of the patients lasted more than 3 years. In case of recurrence after > 2 years, the same therapy can be used, in case of a relapse within a shorter period of time different treatment schedules are recommended. High-dose chemotherapy with an autologous transplant of stem cells obtained from peripheral blood is only recommended after the first recurrence for people under 65 years of age without contraindications. The text analyses the benefits of the new drugs for the treatment of Waldenström macroglobulinemia (bendamustine, thalidomide, lenalidomide, ibrutinib and high-dose chemotherapy).

[Pomalidomide in the treatment of multiple myeloma - own experience and overview of literature]. / Pomalidomid v lécbe mnohocetného myelomu - vlastní zkusenosti a prehled literatury.

In the Czech Republic, pomalidomide is covered for patients with multiple myeloma (in combination with dexamethasone), in the treatment of patients with relapsed and refractory multiple myeloma, who underwent at least 2 previous treatment schedules including both lenalidomide and bortezomibe, with disease progression despite the last therapy (i.e. during the therapy or within 60 days of its end), for whom the only remaining alternative of treatment (apart from pomalidomide) is that using high-dose dexamethasone, and who are not indicated for myeloablative treatment followed by a transplant of stem cells. At our centre pomalidomide was used in 53 patients at a median age of 66 years based on this indication. Pomalidomide was administered in 1 daily dose over 21 days in 28-day cycles. Considering the risk of thromboembolism occurring in this therapy, all patients were administered a prophylactic dose of low-molecular-weight heparin. No patient achieved complete remission (Czech Republic), 5 patients (9.4 %) achieved very good partial remission (VGPR), partial remission (PR) was achieved by 16 (30.2 %) patients, a minimum therapeutic response (MR) was recorded for 6 (11.3 %) patients. The median number of administered cycles was 4.4 (1-22). 16 (28.5 %) patients received treatment for more than 6 months. The overall survival median cannot be evaluated so far due to a short follow-up period. Nonetheless it was possible to evaluate a median time interval to progression (TTP) for the patients, which amounted to 7.0 (3.8-8.2) months. These results are consistent with large registration studies where therapeutic response (at least PR) is reached by 1/3 of the patients and medians of therapeutic response range between 7-10 months. Pomalidomide is a medicine with very good tolerance which is efficient in patients with a progressing multiple myeloma.Key words: lenalidomide - multiple myeloma - pomalidomide - thalidomide.

[Monoclonal immunoglobulin (M-Ig) and skin diseases from the group of mucinoses--scleredema adultorum Buschke and scleromyxedema. Description of four cases and an overview of therapies]. / Monoklonální imunoglobulin a kozní nemoci ze skupiny mucinóz--scleredema adultorum Buschke a scleromyxedema: popis 4 prípadu a prehled lécebných mozností.

INTRODUCTION: The mucinoses of the type of scleredema and scleromyxedema are diseases marked by excessive production of mucin deposits in the skin and subcutaneous tissue, which causes skin hardening. The skin and subcutaneous deposits hamper the movement of limbs, the thorax as well as mouth. The same mechanism also damages other organs (the heart, lungs, oesophagus). It is probably caused by the stimulation of mucin production in fibroblasts by immunoglobulins, frequently monoclonal immunoglobulin. Therefore these diseases are typically associated with monoclonal gammopathy. CASE REPORTS: We describe a cohort of 4 patients, skin manifestations were twice identified as scleredema and twice as scleromyxedema. All the four patients had type IgG monoclonal immunoglobulin and had clonal plasma cells in the bone marrow proven by histologic examination and flow cytometry. Therefore we commenced chemotherapy in all of them. In one case this chemotherapy was ended by a high-dose chemotherapy with transplanting of autologous red blood cells. This therapy attained the complete disappearance of monoclonal immunoglobulin as well as cutaneous and extracutaneous manifestations of scleredema (obstipation). In one case chemotherapy led to partial hematologic remission and partial improvement of skin manifestations. The other two patients did not respond to standard chemotherapy. The condition of one of them resulted in dermato-neuro syndrome (confusion, somnolence passing into coma and grand mal seizure) and improved following an intensive treatment including also intravenous application of immunoglobulins in a dose of 2 g/per 1 kg weight. This patient has now been under long-term treatment with these immunoglobulins, during which the skin symptoms have significantly diminished, but the concentration of monoclonal immunoglobulin has not changed. The fourth patient not responding to standard chemotherapy was treated with intravenous immunoglobulins also in a dose of 2 g/per 1 kg of weight 1× in a month. After 4 applications the thickening of skin and subcutaneous tissue moderately diminished, so the range of possible movement of the upper limbs and neck became larger and the itchy skin morphs which accompanied the disease disappeared completely. CONCLUSION: It is possible to use chemotherapy and high-dose chemotherapy in the treatment of mucinosis associated with monoclonal gammopathy, as in the treatment of multiple myeloma. If such treatment is not possible or it has not attained disappearance of monoclonal immunoglobulin, improvement can be achieved through repeated application of intravenous immunoglobulins. The treatment with intravenous immunoglobulins in an immunomodulation dose of 2 g/per 1 kg of weight effects the moderation of skin manifestations, but it does not lead to the decrease in monoclonal immunoglobulin.
