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.

Non-small cell lung cancer (NSCLC) represents 80 % of diseases considering all patients with lung cancer. NSCLC comprises all histological types except for the small cell cancer. The treatment is chosen based on a clinical stage, morphological diagnosis and performance status of patients. In the low clinical stages a surgical solution is indicated. An alternative is radiotherapy. In some cases adjuvant treatment is indicated. In the locally advanced and metastatic stages chemotherapy and biological therapies are available and in recent time also immunotherapy is used. With regard to locally advanced diseases radiotherapy should also be considered.Key words: biological treatment - chemotherapy - immunotherapy - therapy - non-small cell lung cancer.

In the broadest sense, the term immunocompromised individual means a person with any impairment of infection resistance, whether it is deficiency or impairment of innate resistance (by another name impairment of non-specific resistance), or impairment of acquired resistance (impairment of specific immunity). Pneumonia in immunocompromised patients is characterized by a different microbiological spectrum. Apart from common pathogens there are also opportunistic agents involved in this group of patients. Management of pneumonia in immunocompromised patients is often decisive for their future fate. Very rare are innate immune deficiencies. Acquired immune deficiencies are far more common. They are often combined with disorders of non-specific resistance. The most frequent cause of acquired immune deficiency is another illness or a medical treatment. The diagnosing and treatment of pneumonias in immunocompromised patients are usually highly specialized and they unquestionably require a collaboration with microbiologists who are concerned with these problems.Key words: diagnostics - etiology - pneumonia in immunocompromised patients - prophylaxis - treatment.

Nosocomial pneumonia (hospital-acquired pneumonia - HAP) is the form of pneumonia the symptoms of which present after more than 2 days (> 48 hours) of admission to hospital or as late as 14 days of discharge from hospital. The HAP pneumonias represent 13-18 % of all nosocomial infections. Incidence of HAP is the most frequent in mechanically ventilated patients. The type and representation of HAP agents primarily depends on the length of a patients stay in hospital and on their condition and character of treatment. Diagnosing of pneumonia is based on anamnesis, physical and X-ray findings, results of examination of microbiological samples from the respiratory tract, hemoculture, the pleural effusion test, serological, hematological and biochemical tests. Antibiotic treatment is key to the comprehensive treatment of HAP. The HAP treatment always requires the dosing of antibiotics near the upper limit of the possible range. A precondition for successful avoidance of HAP pneumonias is the creation of a preventive programme with active engagement of medical staff.Key words: diagnostics - HAP pneumonia - treatment - ventilator-associated pneumonia.

Common variable immunodeficiency disorder belongs to the most common primary human immunodeficiencies and it is characterized by primary defective immunoglobulin production. Hypogammaglobulinemia manifests in every age, usually in adult people. There is no gender predisposition. The prevalence is 1 : 25 000-1 : 50 000. The ethiopathogenesis of the majority of CVIDs is unknown. The main clinical respiratory symptoms include recurrent respiratory infects, especially bacterial etiology, sinusitis, bronchitis, pneumonia, leading to bronchiectasis and lung fibrosis. Interstitial lung fibrosis and granulomatosis often manifest at diagnosis of CVID and they are negative prognostic factors of the disease.

Sarcoidosis is systematic granulomatous disease of unknown etiology which can affect any organ. Sarcoidosis belongs to diseases called interstitial lung diseases. Our study is a retrospective analysis of 169 patients (100 females and 69 males), whom we diagnosed sarcoidosis at our pulmonary department in years 2005-2010. Aim of the analysis was to find out prognostic factors and to describe the course of disease. Median age of sarcoidosis patients was 48 years (20-79). Females : males ratio was 1.5 : 1. Non smoker : smoker (or former smoker) ratio was 2.2 : 1. Familial occurrence was observed in 4 patients (2.4%). At diagnosis, stage 0 was present in 6 (3.5%) patients, stage I in 58 (34%) patients, stage II in 84 (49.5%) patients, stage III in 18 (11%) patients, and stage IV in 3 (2%) patients. Diagnosis was confirmed by histology in 111 patients. In 76 patients there was extrapulmonary sarcoidosis. The coincidence of sarcoidosis with autoimmune diseases was observed in 10 patients; 6 patients developed trombembolic disease. One patient suffered from sarcoidosis with cystic fibrosis. Spontaneous resolution was seen in 65 (38.5%) patients; 37 (64%) stage I patients, 26 (31%) stage II patients, and 2 (11%) stage III patients. One hundred one patients (60%) received corticosteroids. Adverse events of corticosteroid therapy were observed in 28 (26%) patients. In sarcoidosis patients with spontaneous resolution, no relapse of disease was observed. On the other hand, eleven (11%) patients treated with glucocorticosteroids relapsed. Median time to sarcoidosis relapse was 6 months (2-34). The age under 40 years, the X-ray stage I or II, the high CD4/CD8 ratio in bronchoalveolar fluid, pulmonary involvement, and therapy need for a period shorter than 2 years were assessed as a significant good prognostic factors. Observed lethality of our patient cohort was 1.2% (2 patients; both deaths related to sarcoidosis).

We describe a case of an adult patient, whom sarcoidosis was diagnosed at first and cystic fibrosis was also discovered 2 years later on. Cystic fibrosis and sarcoidosis are uncommon diseases that only rarely occur together. On the other hand, the coincidence of sarcoidosis and cystic fibrosis is possible, and, moreover, one of the diseases can remain undiagnosed long time. Relationship between sarcoidosis and cystic fibrosis seems not to be probable, in accordance with recent medical reports, and the coincidence of both conditions appears as sporadic.
