Previous Traditional Medicine Use for Sore Throat among Children Evaluated for Rheumatic Fever in Northern Uganda.

Timely diagnosis of group A streptococcal (GAS) sore throat coupled with appropriate antibiotic treatment is necessary to prevent serious post-streptococcal complications, including rheumatic fever (RF) and rheumatic heart disease (RHD). Traditional medicine (TM) is a known common adjunct to formal medical care in sub-Saharan Africa. A better understanding of health-seeking behavior for sore throat both within and outside the formal medical system is critical to improving primary prevention efforts of RF and RHD. A prospective mixed-methods study on the use of TM for sore throat was embedded within a larger epidemiological study of RF in Northern Uganda. Children presenting with symptoms of RF were interviewed about recent TM use as well as health services use for sore throat. One hundred children with a median age of 10 years (interquartile range: 6.8-13 years) completed the TM interview with their parent/guardian as part of a research study of RF. Seventeen, or 17%, accessed a TM provider for sore throat as part of the current illness, and 70% accessed TM for sore throat in the past (73% current or past use). Of the 20 parents who witnessed the TM visit, 100% reported use of crude tonsillectomy. Penicillin was the most frequently prescribed medication by TM providers in 52% of participants who were seen by a TM provider. The use of TM among children presenting with symptoms of sore throat in northern Uganda is common and frequently used in tandem with diagnostic services offered through the formal healthcare system. Engagement with TM practitioners may provide an important avenue for designing effective primary prevention and management strategies of RF and reduce the global burden of RHD.

Statistics on the use of cardiac electronic devices and interventional electrophysiological procedures in Africa from 2011 to 2016: report of the Pan African Society of Cardiology (PASCAR) Cardiac Arrhythmias and Pacing Task Forces.

Aims: To provide comprehensive information on the access and use of cardiac implantable electronic devices (CIED) and catheter ablation procedures in Africa. Methods and results: The Pan-African Society of Cardiology (PASCAR) collected data on invasive management of cardiac arrhythmias from 2011 to 2016 from 31 African countries. A specific template was completed by physicians, and additional information obtained from industry. Information on health care systems, demographics, economics, procedure rates, and specific training programs was collected. Considerable heterogeneity in the access to arrhythmia care was observed across Africa. Eight of the 31 countries surveyed (26%) did not perform pacemaker implantations. The median pacemaker implantation rate was 2.66 per million population per country (range: 0.14-233 per million population). Implantable cardioverter-defibrillator and cardiac resynchronization therapy were performed in 12/31 (39%) and 15/31 (48%) countries respectively, mostly by visiting teams. Electrophysiological studies, including complex catheter ablations were performed in all countries from Maghreb, but only one sub-Saharan African country (South Africa). Marked variation in cost (up to 1000-fold) was observed across countries with an inverse correlation between implant rates and the procedure fees standardized to the gross domestic product per capita. Lack of economic resources and facilities, high cost of procedures, deficiency of trained physicians, and non-existent fellowship programs were the main drivers of under-utilization of interventional cardiac arrhythmia care. Conclusion: There is limited access to CIED and ablation procedures in Africa. A quarter of countries did not have pacemaker implantation services, and catheter ablations were only available in one country in sub-Saharan Africa.

Effect of coenzyme Q10 on the incidence of atrial fibrillation in patients with heart failure.

BACKGROUND: There is mounting evidence to support the influence of inflammation and oxidative stress in the pathogenesis of atrial fibrillation (AF) and heart failure (HF). The efficacy of coenzymeQ10 (CoQ10), an antioxidant used as an adjunct treatment in patients with AF and HF, remains less well established. METHODS: Consecutive patients with HF were randomized and divided into 2 groups: the CoQ10 group (combined administration of common drugs and CoQ10) and the control group (administration of common drugs). Ambulatory electrocardiogram Holter monitoring (24 hours), Doppler echocardiography, and evaluation of inflammatory cytokines were performed before treatment and 6 and 12 months after treatment. RESULTS: One hundred two patients (72 male and 30 female patients), with ages ranging from 45 to 82 years (mean age, 62.3 years), were examined. There was significant reduction in the level of malondialdehyde (3.9 ± 0.7 vs 2.5 ± 0.6 ng/mL; 3.9 ± 0.7 vs 2.3 ± 0.5 ng/mL, P < 0.05) in the CoQ10 group, whereas there was no significant difference (3.3 ± 0.8 vs 2.9 ± 0.8 ng/mL; 3.3 ± 0.8 vs 2.9 ± 0.5 ng/mL) in the control group after 6 and 12 months. Three patients (6.3%) in the CoQ10 group and 12 patients (22.2%) in the control group had episodes of AF after 12 months' treatment (P = 0.02). Four patients with AF in the control group went through the third Holter recording. CONCLUSIONS: CoenzymeQ10 as adjuvant treatment in patients with HF may attenuate the incidence of AF. The mechanisms of the effect perhaps have relation with the reduced levels of malondialdehyde.

Combined statin/coenzyme Q10 as adjunctive treatment of chronic heart failure.

Statins and coenzyme Q10 are both used as adjuncts in the treatment of chronic heart failure (CHF) due to their anti-inflammatory and antioxidant effects, respectively. And both have been variously shown to improve cardiac function in patients with CHF. The two agents interact in two ways; statins inhibit coenzyme Q10 synthesis through inhibition of HMG-CoA reductase, the rate limiting step in cholesterol synthesis, also shared by coenzyme Q10. Secondly, they both exhibit their antioxidant effects through activation of the enzyme superoxide dismutase, the rate limiting step in nitric oxide metabolism and main antioxidant mechanism of coenzyme Q10. We hypothesize that the interaction between statins and coenzyme Q10 is more than just a replacement, but a synergistic interaction on superoxide dismutase that could result in better cardiac function, improvement in patient symptoms, shortening of duration of hospital stay and improvement in patient quality of life.
