Towards a toolkit for cross-neglected tropical disease morbidity and disability assessment.

BACKGROUND: Neglected tropical diseases (NTDs) are a group of often chronic and disabling infectious conditions, closely related to poverty and inequities. While it is estimated that millions of people are affected, accurate and internationally comparable data about NTD-related morbidity and disability are lacking. Therefore we aimed to develop and pilot a toolkit to assess and monitor morbidity and disability across NTDs. METHODS: A cross-sectional, non-random survey design with a mixed methods approach was used. We conducted a literature review on existing tools to assess and monitor disability, followed by a Delphi study with NTD experts to compile a prototype toolkit. A first-phase validation study was conducted in Northeast Brazil among people with Chagas disease, leishmaniasis, leprosy and schistosomiasis. RESULTS: Instruments included were the clinical profile, WHODAS, P-scale, SRQ, WHOQOL-BREF and WHOQOL-DIS. Most questions in the various instruments were readily understood with the exception of the WHOQOL-BREF, where additional explanations and examples were often needed. The respondents were very appreciative of the instruments and found it valuable to have the opportunity to talk about these aspects of their condition. CONCLUSIONS: Our findings support the acceptability and relevance of five of the six instruments tested and the concept of a cross-NTD toolkit.

Diagnostic utility of bone marrow examination for the assessment of patients with fever of unknown origin: a 10-year single-centre experience.

Bone marrow (BM) examination is included in the diagnostic algorithm of fever of unknown origin (FUO), although its role is not clearly determined. The purpose of this study was to assess the role of BM studies in patients with FUO. We retrospectively reviewed 45 consecutive patients (25% human immunodeficiency virus-positive) with FUO who underwent a BM study in the University Hospital of Salamanca from 2000 to 2010. We analysed the diagnostic role of BM smears, multiparameter flow cytometry analysis, histology and microbiological cultures. Five patients (11%) were finally diagnosed by BM study (three had an infectious disease and two were found to have haematological malignancies), all of whom were immunocompetent patients. Histology was the most useful study (diagnosis was obtained in 4/5 patients), while BM cultures did not establish the final diagnosis in any patient. Flow cytometry established the diagnosis in one patient, although this patient was also diagnosed by histology. In conclusion, BM study is useful for establishing the aetiology of FUO. BM biopsy for histological examination should be always mandatory if a BM examination is performed.

Epidemiology of leishmaniasis in Spain based on hospitalization records (1997-2008).

All the records from the Spanish information system for hospital data of patients diagnosed with leishmaniasis during a 12-year period (1997-2008) were studied. The 2,028 individuals were hospitalized because of leishmaniasis, as indicated by the principal diagnostic code. The average hospitalization rate was 0.41/100,000 inhabitants. One-third of them were co-infected with human immunodeficiency virus (HIV). The incidence of hospitalization in the adult population with leishmaniasis co-infected with HIV increased with age, peaked at 35-39 years of age and subsequently declined. In the pediatric population, all leishmaniasis cases occurred in HIV-negative children. Incidence of hospitalizations was highest in Madrid and in the Mediterranean coast. The cost per inpatient hospital care was $9,601 corresponding to an annual direct cost of more than $1.5 million for inpatient care alone. The economical burden of leishmaniasis is not neglectable and in the 12-year study period it represented more than $19 million.
