Introduction: Lopinavir/ritonavir-based antiretroviral therapy (ART) is recommended for all HIV-infected children less than three years. However, little is known about its field implementation and effectiveness in West Africa. We assessed the 12-month response to lopinavir/ritonavir-based antiretroviral therapy in a cohort of West African children treated before the age of two years.Methods: HIV-1-infected, ART-naive except for a prevention of mother-to-child transmission (PMTCT), tuberculosis-free, and less than two years of age children with parent’s consent were enrolled in a 12-month prospective therapeutic cohort with lopinavir/ritonavir ART and cotrimoxazole prophylaxis in Ouagadougou and Abidjan. Virological suppression (VS) at 12 months (viral load [VL] <500 copies/mL) and its correlates were assessed.Results: Between May 2011 and January 2013, 156 children initiated ART at a median age of 13.9 months (interquartile range: 7.8–18.4); 63% were from Abidjan; 53% were girls; 37% were not exposed to any PMTCT intervention or maternal ART; mother was the main caregiver in 81%; 61% were classified World Health Organization Stage 3 to 4. After 12 months on ART, 11 children had died (7%), 5 were lost-to-follow-up/withdrew (3%), and VS was achieved in 109: 70% of children enrolled and 78% of those followed-up. When adjusting for country and gender, the access to tap water at home versus none (adjusted odds ratio (aOR): 2.75, 95% confidence interval (CI): 1.09–6.94), the mother as the main caregiver versus the father (aOR: 2.82, 95% CI: 1.03–7.71), and the increase of CD4 percentage greater than 10% between inclusion and 6 months versus <10% (aOR: 2.55, 95% CI: 1.05–6.18) were significantly associated with a higher rate of VS. At 12 months, 28 out of 29 children with VL ≥1000 copies/mL had a resistance genotype test: 21 (75%) had ≥1 antiretroviral (ARV) resistance (61% to lamivudine, 29% to efavirenz, and 4% to zidovudine and lopinavir/ritonavir), of which 11 (52%) existed before ART initiation.Conclusions: Twelve-month VS rate on lopinavir/ritonavir-based ART was high, comparable to those in Africa or high-income countries. The father as the main child caregiver and lack of access to tap water are risk factors for viral failure and justify a special caution to improve adherence in these easy-to-identify situations before ART initiation. Public health challenges remain to optimize outcomes in children with earlier ART initiation in West Africa.
La COVID-19 est due au virus SARS-CoV-2 génétiquement semblable au virus du syndrome respiratoire aigu sévère (SARS). En pédiatrie, les formes cliniques ont un caractère bénin. En Guinée, suite à la pandémie du COVID-19 dont l´épicentre était Conakry, des cas pédiatriques ont été observés au CTEPI de Donka. L´objectif de cette étude était de déterminer leur profil épidémiologique. Etude transversale de type descriptif de 04 mois chez les enfants de 0 à 16 ans admis au CTEPI Donka. Sur 7308 patients provenant principalement des 5 communes de Conakry hospitalisés au CTEPI, 189 étaient âgés de 0 à 16 ans, soit 2, 59%. La tranche de 0-4 ans était plus représentée (38,62%) avec un sex-ratio (F/M) de 1,52; 62,96% étaient des élèves, 70% des enfants résidaient à Conakry, 28,57% des mères étaient des marchandes et personnes contactes dans 39,68%; 37,57% des pères étaient des fonctionnaires, 2,65% des enfants avaient des antécédents de drépanocytose et 1,59% de rhinite allergique. Les cas asymptomatiques représentaient 52,38% et les cas confirmés 74, 6%; les symptômes étaient: fièvre, rhinorrhée, céphalées, toux, douleurs abdominales, éternuement, diarrhée, asthénie physique. La proportion des cas pédiatriques infectés au COVID-19 au CTEPI de Donka est faible. Les enfants de 5 ans et plus sont plus concernés et près de 50% était asymptomatique. Les symptômes dominants sont: fièvre, céphalées, rhinorrhée, toux, douleurs abdominales, éternuement, diarrhée, asthénie physique.
Objective: To compare the frequency of replication-competent virologic rebound with and without nirmatrelvir-ritonavir treatment for acute COVID-19. Secondary aims were to estimate the validity of symptoms to detect rebound and the incidence of emergent nirmatrelvir-resistance mutations after rebound. Design: Observational cohort study. Setting: Multicenter healthcare system in Boston, Massachusetts. Participants: We enrolled ambulatory adults with a positive COVID-19 test and/or a prescription for nirmatrelvir-ritonavir. Exposures: Receipt of 5 days of nirmatrelvir-ritonavir treatment versus no COVID-19 therapy. Main Outcome and Measures: The primary outcome was COVID-19 virologic rebound, defined as either (1) a positive SARS-CoV-2 viral culture following a prior negative culture or (2) two consecutive viral loads ≥4.0 log10 copies/milliliter after a prior reduction in viral load to <4.0 log10 copies/milliliter. Results: Compared with untreated individuals (n=55), those taking nirmatrelvir-ritonavir (n=72) were older, received more COVID-19 vaccinations, and were more commonly immunosuppressed. Fifteen individuals (20.8%) taking nirmatrelvir-ritonavir experienced virologic rebound versus one (1.8%) of the untreated (absolute difference 19.0% [95%CI 9.0-29.0%], P=0.001). In multivariable models, only N-R was associated with VR (AOR 10.02, 95%CI 1.13-88.74). VR occurred more commonly among those with earlier nirmatrelvir-ritonavir initiation (29.0%, 16.7% and 0% when initiated days 0, 1, and ≥2 after diagnosis, respectively, P=0.089). Among participants on N-R, those experiencing rebound had prolonged shedding of replication-competent virus compared to those that did not rebound (median: 14 vs 3 days). Only 8/16 with virologic rebound reported worsening symptoms (50%, 95%CI 25%-75%); 2 were completely asymptomatic. We detected no post-rebound nirmatrelvir-resistance mutations in the NSP5 protease gene. Conclusions and Relevance: Virologic rebound occurred in approximately one in five people taking nirmatrelvir-ritonavir and often occurred without worsening symptoms. Because it is associated with replication-competent viral shedding, close monitoring and potential isolation of those who rebound should be considered.
Objectives Sjögren’s syndrome is rare in children and most often secondary. It frequently affects girls and is characterized by dry eye syndrome, mouth and sometimes systemic involvement. Its diagnosis is difficult to establish in children. We report a series of 15 cases of Sjögren’s syndrome in order to clarify the peculiarities of this condition in children. Patients and methods This retrospective study was carried out over a 2-year period focused on children under 16 years of age who had been followed for Sjögren’s syndrome in the rheumatology and pediatric departments. Patient data were collected and then analyzed by STATA/SE version 11.2 software. Anonymity and respect for ethical rules were the norm. There was no connection between the patients and the researchers. Description of cases The mean age of the patients was 11 years with extremes of 5–15 years. History reveals that a dry mouth was found in more than half of the cases, or in 10 (66.7%) patients. Clinical examination found oral ulceration and periodontitis in equal proportions, 6 (40%). The immunological workup and the biopsy of the accessory salivary glands served as diagnostic evidence in the 15 patients according to the US–European criteria of 2002. Conclusion Sjögren’s syndrome is a rare entity in pediatrics. Its diagnosis is difficult to establish in pediatrics and its severity is linked to the occurrence of late visceral and lymphomatous sicca syndrome. Rapid diagnosis and initiation of a synthetic antimalarial (hydroxychloroquine) increases the hope of a cure.
