[Implementation of the International Health Regulations in Cuba: evaluation of basic capacities of the health sector in selected provinces]. / Implementación del Reglamento Sanitario Internacional en Cuba: evaluación de capacidades básicas del sector salud en provincias seleccionadas.

OBJECTIVE: Obtain baseline information on the status of the basic capacities of the health sector at the local, municipal, and provincial levels in order to facilitate identification of priorities and guide public policies that aim to comply with the requirements and capacities established in Annex 1A of the International Health Regulations 2005 (IHR-2005). METHODS: A descriptive cross-sectional study was conducted by application of an instrument of evaluation of basic capacities referring to legal and institutional autonomy, the surveillance and research process, and the response to health emergencies in 36 entities involved in international sanitary control at the local, municipal, and provincial levels in the provinces of Havana, Cienfuegos, and Santiago de Cuba. RESULTS: The polyclinics and provincial centers of health and epidemiology in the three provinces had more than 75% of the basic capacities required. Twelve out of 36 units had implemented 50% of the legal and institutional framework. There was variable availability of routine surveillance and research, whereas the entities in Havana had more than 40% of the basic capacities in the area of events response. CONCLUSIONS: The provinces evaluated have integrated the basic capacities that will allow implementation of IHR-2005 within the period established by the World Health Organization. It is necessary to develop and establish effective action plans to consolidate surveillance as an essential activity of national and international security in terms of public health.

Low prevalence of Helicobacter pylori among symptomatic children from a hospital in Havana, Cuba.

The aims of this study were to assess the prevalence of Helicobacter pylori infection and to introduce a new algorithm to improve its diagnosis in Cuban symptomatic children. One hundred and thirty-three consecutive children with upper gastrointestinal symptoms were studied. Patients were endoscoped and antral biopsies were obtained for rapid urease test (RUT), culture and histology. Prevalence of H. pylori infection was 30.8%. No statistical differences were found concerning demographic, socio-economic factors or chief clinical complaints, between H. pylori-positive and negative children, except for haematemesis, which was significantly higher in infected children (p = 0.003). Histologically, there was statistical association between moderate chronic gastritis in infected children (p = 0.04). Culture and RUT had the highest specificity and sensitivity, respectively. The prevalence of H. pylori infection in Cuban symptomatic children is similar to the one observed in developed countries. Culture and RUT is a useful combination to diagnose H. pylori infection in paediatric patients.

Kaposi's sarcoma-associated herpesvirus load in asymptomatic contacts of Cuban epidemic KS patients.

To evaluate the pathogenic mechanisms and transmission routes involved in KSHV infection in 22 Cuban individuals who maintained close contact with epidemic KS patients, real-time PCR was used to quantify KSHV-DNA in clinical samples of plasma, saliva and peripheral blood mononuclear cells (PBMC). KSHV-DNA was detected in 72.7% (16/22) of the contacts. The highest levels of KSHV load were detected in saliva, followed by PBMC (average log copies/100 ng DNA = 1.28 and 1.12), while significantly lower levels were detected in plasma (average log copies/ml = 0.37). Two of three intra-domiciliary and two serodiscordant sexual contacts of AIDS-KS patients were infected with KSHV. The rate of KSHV-DNA detection in saliva and PBMC samples in men who have sex with men (MSM) was significantly higher than in heterosexuals (HT) (p = 0.014). MSM were more likely to harbor KSHV-DNA in saliva when compared with HT individuals (OR 4.33; 95% CI 1.117-16.8). These results emphasize that, in Cuba, KSHV horizontal transmission through saliva may occur, although homosexual behavior may predispose an individual to KSHV acquisition. Even in the absence of disease, KSHV could cause an asymptomatic systemic infection in individuals who maintain close contact with AIDS-KS patients.

Phenotypic and genetic characterization of antimicrobial profiles of Helicobacter pylori strains in Cuba.

The study evaluated the antibiotic resistance patterns of Helicobacter pylori strains against metronidazole and clarithromycin in a hospital in Havana, Cuba. Eighty-five percent, 22.5%, and 10% of 40 H. pylori strains investigated were resistant to metronidazole, ciprofloxacin, and clarithromycin respectively but all were susceptible to amoxicillin and tetracycline. RdxA truncation was found only in metronidazole-resistant strains. In such strains, reported are eight and two novel mutations in the rdxA and frxA genes respectively. Two-point mutations in the 23S rRNA genes of clarithromycin-resistant strains were detected. A high prevalence of metronidazole resistance was found in Cuban H. pylori strains. Mutations in the rdxA gene may contribute more significantly than frxA gene to the high level of resistance to metronidazole. This study supports the need to continue monitoring the antibiotic susceptibility in H. pylori in Cuba to guide the treatment of such infection.

Simultaneous quantification of human herpesvirus 8 DNA by real time PCR in different tissues of HIV infected cuban patients with Kaposi's sarcoma.

In Cuba, previous reports have shown an increase of epidemic KS, reaching a total of 120 cases by the end of 2007, despite the use of HAART. To evaluate and compare the role of human herpes virus 8 (HHV-8) viral loads in different compartments of AIDS-related Kaposi's sarcoma (AIDS-KS) patients real-time polymerase chain reaction (RT-PCR) was used to determine the genome copy number of HHV-8 in plasma, saliva, tissue and peripheral blood mononuclear cells (PBMC) of 49 AIDS-KS patients. Overall, 98% of AIDS-KS patients harbored detectable HHV-8. HHV-8 could be detected in 91.6% of KS tissue lesions showing the highest viral load (median log = 3.14 copies/100 ng DNA) followed by saliva and PBMC which were positive in 78%, and 69.2%; respectively. In contrast, HHV-8 was detected in only 37% of plasma samples, which also showed lower viral loads. Men who had sex with men (MSM) were more likely to have three-times higher HHV-8 genome copies in KS lesions when compared with tissues from heterosexuals individuals (OR 3; 95% CI 1.1 to 12.5). These results emphasize the systemic nature of HHV-8-infection and demonstrate the possible role of saliva in HHV-8 transmission among MSM.

[Response capacity for epidemic emergencies: recommendations for country self-evaluation]. / Capacidad de respuesta a emergencias epidémicas: recomendaciones para la autoevaluación nacional.

Communicable diseases that have appeared or reappeared in recent years have demonstrated their great potential for spreading and their capacity to overwhelm a country's resources, causing major emergencies. The recent SARS epidemic showed that only health systems that have been strengthened and that have the response capacity for events of this kind will be able to handle future contingencies. Governments have recognized the need to support initiatives to strengthen their countries' capacities in surveillance, prevention, and the control of emergencies caused by epidemics. This piece identifies essential components that will make it possible to guide the efforts of governments, with the support of the Pan American Health Organization and other international organizations, toward achieving a common goal: establishing for countries warning and epidemic-emergency response systems that are appropriate and effective.
