Comparison of the Ivermectin and Lopinavir/Ritonavir Treatment Outcomes among COVID-19 Mild to Moderate Cases in Kaduna State

BACKGROUND

Ivermectin has been a popular anti-parasitic drug since the late 1970s. The promising result of in-vitro studies on the antiviral activity of the drug has led clinicians in many countries to use this drug to treat COVID-19 patients. This study determined and compared the mean number of days at clinical recovery for mild to moderate cases of COVID -19 treated with Lopinavir/Ritonavir (Alluvia) and Ivermectin at the Kaduna State Infectious Disease Control Centres.

METHODS

This was a comparative cross-sectional study conducted among 300 mild to moderate COVID- 19 cases enrolled for the study. The outcome variables were the time required for the resolution of symptoms from the onset and at commencement of the treatment regimens. Data were collected from patient folders using a questionnaire. Data were analysed with the IBM SPSS Version 25.0 and STATA/SE 13. Statistical significance was set at p<0.05.

RESULTS

The mean recovery time (MRT) from symptom onset was significantly lower for Covid-19 patients treated with ivermectin (7.15±4.18 days) compared to lopinavir/ritonavir (9.7±5.3 days), 95%CI=7.37-9.62. Multivariate logistic regression showed that there was no significant relationship between the patients age (AOR=0.36, 95%CI=0.09-1.49), sex (AOR=0.34,95%CI=0.54-5.93), educational status (AOR=1.04, 95%CI=0.3-3.57), marital status (AOR=0.55,95%CI=0.14-2.11) place of treatment (AOR=1.66, 95%CI=0.54-5.11) and MRT. There was also no significant relationship between patients' comorbid chronic illness (AOR=0.83, 95%CI=0.27-2.61) and MRT.

CONCLUSION

The mean recovery time for COVID-19 patients managed with ivermectin was slightly lower than for the lopinavir/ ritonavir regimen.

RECOMMENDATION

Clinical trials to further prove the efficacy of Ivermectin as a supportive therapy in clinical management of mild to moderate cases of COVID-19 in this setting should be carried out.

DETERMINANTS OF CHOICE OF HEALTH FACILITY FOR REPRODUCTIVE MORBIDITY BY FEMALE TRADERS IN A NIGERIAN CITY

BACKGROUND

Reproductive health (RH) services are important to reduce reproductive morbidity and mortality. This is only possible if such services are used. Knowledge of the determinants of choice health facility for reproductive morbidity is useful to design interventions aimed at increasing utilization of RH services.

OBJECTIVE

This study therefore explored the determinants of choice of health facility for reproductive morbidity among female traders within Ibadan metropolis.

METHODS

This was a cross-sectional study using interviewer-administered questionnaire among 410 female traders aged 15-49 years selected by systematic random sampling in Aleshinloye market in the city of Ibadan, Nigeria. Government and private hospitals were classified as orthodox health facilities. Data was analysed using logistic regression at 5% significance level.

RESULTS

Mean age was 34.6 ± 7.8, 78.2% were married and 58.7% had secondary education. Above half (52.9%) used orthodox health facilities. Perceived quality of care influenced the use of orthodox facilities and likelihood of using the same facility in the future. Factors predicting the use of orthodox health services were social economic status (OR 2.77 95%CI 1.06-6.73), delay in attaining conception (OR 2.70 95%CI 1.39-5.22), menstrual problems (OR 2.15 95%CI 1.19-3.90) and complications in previous pregnancy (OR 2.11 95%CI 1.21-3.78).

CONCLUSION

The use of orthodox health facilities was affected by respondents' past experience of reproductive morbidity and socioeconomic status. These factors should be borne in mind in planning interventions for improvement in reproductive health service utilisation.

Plasma Adenosine Deaminase Enzyme Reduces with Treatment of Pulmonary Tuberculosis in Nigerian Patients: Indication for Diagnosis and Treatment Monitoring

Tuberculosis(TB)-specific host biomarkers for diagnosis and monitoring of treatment response have been identified as priorities for TB research. Macrophage and T cell lymphocytes play vital roles in Mycobacterium tuberculosis immune response and their associated biomarkers could form good candidates for diagnosis and treatment monitoring. The enzyme adenosine deaminase (ADA) is produced mainly by monocytes and macrophages and increase in biological fluids in the course of infection with microorganisms infecting macrophages. This study comprised sixty-eight (68) participants; twenty-four (24) multi-drug-resistant TB(MDR-TB) patients, twenty-four (24) drug-sensitive TB patients(DS-TB) and twenty (20) non-TB apparently healthy individuals. Five (5) milliliters of blood was drawn before commencement of chemotherapy and 6 anti-TB therapy. In DSTB and MDR-TB patients before commencement of chemotherapy and 6 months of anti-TB treatment, the mean plasma levels of ADA were significantly increased compared with control. At 6 months of anti-TB chemotherapy of DSTB or MDR TB patients, ADA level was significantly decreased compared with before chemotherapy. Plasma ADA in DSTB patients before and 6 months of chemotherapy were not significantly different compared MDR TB patients. Plasma ADA level is a promising biomarker for the screening and treatment monitoring of pulmonary tuberculosis but not to differentiate MDR TB from DSTB patients.

Antioxidant status of adult Nigerian asthmatics: implications for prognosis

Serum antioxidant status of 50 (19M, 31F) adult asthmatic patients, aged 40 to 50 yr and attending the medical outpatient clinic of the University College Hospital, Ibadan, has been assessed, by measurement of serum ascorbic acid, copper, zinc, albumin, uric acid and magnesium levels, to determine the relationship between antioxidant status and severity of bronchial asthma. Twenty-five (25) age matched adults (10M, 15F) served as controls. The test subjects were classified into two groups (1&2) based on the degree of respiratory distress. Questionnaires were also used to obtain data on subjects' fruit and vegetable intake. Fruit and vegetable intake was similar in patients and controls, 96% and 100% respectively reporting adequate intake. Copper (Cu) level was not significantly different between patients and control subjects, but was significantly higher in female asthmatics than in males (p < 0.05). Magnesium (Mg) level was also lower in asthmatics than in control subject (p < 0.001). Plasma Zinc level was not different between patients and control (p > 0.05). The levels of the other antioxidants, vitamin C, uric acid and albumin were all lower in asthmatics than in controls (p < 0.05, p < 0.001, p < 0.001) respectively. The magnesium level of group 2 (severe asthmatics) was lower than in controls (p < 0.05) unlike moderate asthmatics (group 1) which do not differ significantly from controls. These findings support the emerging concept that antioxidants are consumed in this inflammatory disease and that a corresponding increase in antioxidant supply may improve prognosis for bronchial asthma.

Prevalence of headache and migrainous headache in Nigerian Africans: a community-based study

In a door-to-door survey in a Nigerian town with stable population of about twenty thousand, 18,594 subjects were screened with a questionnaire, which involved a complete census, administered by non-doctor, including primary health care personnel. Migrainous headache was diagnosed on the basis of combination of responses to the questionnaire shown in a pilot study validated by neurological examination to have 92% sensitivity and 99% specificity. Crude life time prevalence ratio of at least one episode of headache unspecified was 51 percent (50% in males and 52% in females). The crude prevalence ratio of migrainous headache was 5.3 per 100 (5 per 100 in males and 5.6 per 100 in females), with peak age-specific prevalence ratios in the first decade in both males and females. Migrainous headache was three times as common in females as in males in the second and third decades. Prevalence of migrainous headache in Nigerian Africans appears less than in Caucasians. No social status was at special risk to developing migrainous headache.

Prevalence of the epilepsies in Nigerian Africans: a community-based study

A door-to-door survey to detect commonly occurring neurologic diseases was carried out in Igbo-Ora, a large Nigerian town with a population of approximately 20,000. Effective health care facilities have been operating in the community since 1963. Primary health care workers and nondoctor personnel administered a complete census, a screening questionnaire, and a simple screening neurologic examination. The pretested screening questionnaire had been shown in a pilot study to have a sensitivity of 95% for identifying those with epilepsy. Individuals positive on the screening phase of the survey were evaluated by neurologists and neurosurgeons, who used well-defined criteria to make the diagnosis. There were 101 (48 males and 53 females) who suffered from active epilepsy (5.3 cases/1,000) on prevalence day. The highest age-specific prevalence ratios occurred in those below age 20. The most common of the identifiable seizure types was complex partial seizures (52 cases). The prevalence ratio of epilepsy in this Nigerian town (with an effective health care system) is similar to that reported in some developed countries and several times lower than figures derived from studies in developing countries. These data suggest that an improved health care system would probably reduce the prevalence and burden of epilepsy in developing countries.

Neurological disorders in Nigerian Africans: a community-based study

In a Nigerian town with a stable population of 20,000, a door-to-door survey was conducted, using a questionnaire involving a complete census and a simple neurological evaluation which had previously showed a 95% sensitivity and an 80% specificity for detecting neurological disease. Positive responders were evaluated and categorised, using agreed criteria for diagnoses. Nearly 100% cooperation was obtained. Life prevalence ratio for at least one episode of headache was 51/1000. Crude point prevalence ratio for migrainous headache was 5.3/100, and peak age-specific ratio was in the first decade. Prevalence ratio for epilepsy was 533/100,000 and peak age-specific prevalence ratio occurred in the 5-14 years age groups. The prevalence ratio for peripheral nerve disorders was 268/100,000, and age-specific prevalence ratio for tropical neuropathy increased with age. Prevalence ratio for stroke was rather low at 58/100,000, but was probably due to the people's attitude to the disabled elderly and high mortality of stroke which showed annual mortality rate of 70/100,000 which increased with age to 1519/100,000 per year in the eighth decade. Crude prevalence ratios (cases per 100,000) for others are 112 for neurological complications (including sciatica) of spondylosis, 15 each for poliomyelitis, motor neurone disease, development speech disorders, 10 each for syncope, hereditary neuropathies. Parkinson's disease, benign essential tremor, primary cerebellar degeneration, cerebral palsy, mental retardation, organic psychosis (probable intracranial tumor) and 5 each for muscular dystrophy, pyomyositis, spina bifida occulta, alcohol dependence and cerebral malaria. The implications of the findings are important for development of community neurological services in the developing countries.
