Percepção dos portadores de hanseníase acerca do auto cuidado

This study aimed at evaluating the perception of leprosy patients, the disease, with regard to its concept and self-care practice, as well as their knowledge concerning drug therapy. Fifteen patients participated in the study, of whom 11 were classified as multibacillary and 04 as paucibacillary. Semi-structure interviews containing six guiding questions were used for data collection, and the Collective Subject Discourse (CSD) was utilized as a theoretical framework. Analysis was performed based on the Theory of Complexity. It showed that patients suffer pain, a fact that is reflected on the need to change habits and prevent disability. It also showed that patients have doubts and feel insecure about treatment and prognosis, and that they are also the target of social prejudice even thought the term leprosy has been replaced by Hansen‟s disease. As regards self-care, the subjects showed lack of autonomy, limitations and subjection to instructions from health care professionals, who, according to the discourse that emerged, are mostly responsible for transmitting the knowledge concerning self-care practice. This fact can be explained by evidence of self-knowledge deficit by the the subjects. Concerning polychemotherapy treatment, which is recommended by the Ministry of Health, it was observed that the knowledge concerning its action and adverse effects is precarious. This information is provided during consultation; however, CSD showed that the subjects do not apprehend it. Therefore, health care professionals must instruct their clients not only as regards conventional treatment practices, but they must also help them to know themselves and to improve their critical judgment so that they can choose the best form of living after being diagnosed with the disease, thus guiding self-care by taking such choice into account

Autocuidado na percepção de pessoas com hanseníase sob a ótica da complexidade

Objective: This study aimed to understand how patients with Hansen's Disease perceive self-care from the complexity perspective. Methods: Qualitative, descriptive and exploratory study based on the Collective Subject Discourse. Results: Sample composed of 15 subjects, most of whom were married males (66.6%) with a mean age of 52.3 years and were classified in the polarized forms of the disease. The following themes emerged from the DCS synthesis: having Hansen's Disease, drug therapy, self-care and lifestyle. The study provided visibility to the vertical model, which is largely hegemonic in the tradition of public health care policies, showing concern about only treating the disease, disregarding the complex relationships involved. Conclusion: Acknowledging these limitations and setting strategies to change them in favor of the dialogue among interprofessional team members are challenges to further develop self-care practices and to empower patients in relation to treatment and disease.

O paradigma dualista da hanseníase controle ou eliminação: o período crítico de 2000 a 2005

One of the main tendencies of leprosy worldwide is the simultaneous action of non governmental organizations and official agencies operating eventual different strategies. This paper aims to contribute to such question focusing on some outstanding aspects of respective contemporary evolution. METHODS Application of bibliographic review and contents analysis techniques to primary data from a circumstancial set of open circulation specific publications. RESULTS Successive disagreements registered between both parts refer to the objective to be attained by the fight against the disease, if control or elimination. CONCLUSIONS New perspectives of jointed actions are being searched for now when priority on endemics control is more realistically assumed and social determination is been really considered.

WBC count and functional changes induced by co-administration of clofazimine and clarithromycin, in single and multiple doses, in Wistar rats

Clofazimine and clarithromycin are used to treat leprosy and infections caused by Mycobacterium avium complex. Little data on the toxicity of co-administration of these two drugs are available. Here we evaluated the potential adverse effects of polytherapy with these two drugs in male Wistar rats by determining WBCs counts and other blood cell counts, neutrophilic phagocytosis, and burst oxidative, by flow cytometry. We observed an increase in WBCs, in multiple-dose regimens, and in polymorphonuclear cells, in both single- clarithromycin only and multiple dose regimens. We also observed a reduction in mononuclear cell counts in single and multiple doses. The drugs seem to reverse the mononuclear and polymorphonuclear cell ratio. An increase in oxidative burst was observed in animals treated with the drugs administered either individually or combined. In conclusion, clofazimine and clarithromycin change WBCs counts. Our results may contribute for a better understanding of the mechanisms related to the effects of co-administrating the two drugs.

Use of the polymerase chain reaction to detect Mycobacterium leprae in urine

Leprosy is an infectious disease caused by Mycobacterium leprae. The polymerase chain reaction (PCR) has been applied to detect M. leprae in different clinical samples and urine seems to be attractive for this purpose. PCR was used to improve the sensitivity for diagnosing leprosy by amplifying a 151-bp PCR fragment of the M. leprae pra gene (PCR-Pra) in urine samples. Seventy-three leprosy patients (39 males and 34 females, 14 to 78 years old) were selected for leprosy diagnosis at a reference laboratory in Maringa, PR, Brazil. Of these, 36 were under anti-leprosy multidrug therapy with dapsone and rifampicin for tuberculoid (TT) and dapsone, rifampicin and clofazimine for borderline (BB) and lepromatous (LL) forms. The control group contained 50 healthy individuals without any clinical history of leprosy. DNA isolated from leprosy patients' urine samples was successfully amplified by PCR-Pra in 46.6% (34/73) of the cases. The positivity of PCR-Pra for patients with the TT form was 75% for both patients under treatment and non-treated patients (P = 0.1306). In patients with the LL form, PCR-Pra positivity was 52 and 30% for patients under treatment and non-treated patients, respectively (P = 0.2386). PCR-Pra showed a statistically significant difference in detecting M. leprae between the TT and LL forms of leprosy in patients under treatment (P = 0.0033). Although the current study showed that the proposed PCR-Pra has some limitations in the detection of M. leprae, this method has the potential to be a useful tool for leprosy diagnosis mainly in TT leprosy where the AFB slit-skin smear is always negative.

Lower numbers of natural killer T cells in HIV-1 and Mycobacterium leprae co-infected patients

Natural killer T (NKT) cells are a heterogeneous population of lymphocytes that recognize antigens presented by CD1d and have attracted attention because of their potential role linking innate and adaptive immune responses. Peripheral NKT cells display a memory-activated phenotype and can rapidly secrete large amounts of pro-inflammatory cytokines upon antigenic activation. In this study, we evaluated NKT cells in the context of patients co-infected with HIV-1 and Mycobacterium leprae. The volunteers were enrolled into four groups: 22 healthy controls, 23 HIV-1-infected patients, 20 patients with leprosy and 17 patients with leprosy and HIV-1-infection. Flow cytometry and ELISPOT assays were performed on peripheral blood mononuclear cells. We demonstrated that patients co-infected with HIV-1 and M.leprae have significantly lower NKT cell frequencies [median 0.022%, interquartile range (IQR): 0.0070.051] in the peripheral blood when compared with healthy subjects (median 0.077%, IQR: 0.0320.405, P < 0.01) or HIV-1 mono-infected patients (median 0.072%, IQR: 0.0300.160, P < 0.05). Also, more NKT cells from co-infected patients secreted interferon-? after stimulation with DimerX, when compared with leprosy mono-infected patients (P = 0.05). These results suggest that NKT cells are decreased in frequency in HIV-1 and M.leprae co-infected patients compared with HIV-1 mono-infected patients alone, but are at a more activated state. Innate immunity in human subjects is strongly influenced by their spectrum of chronic infections, and in HIV-1-infected subjects, a concurrent mycobacterial infection probably hyper-activates and lowers circulating NKT cell numbers.
