Leishmania RNA virus 2 (LRV2) exacerbates dermal lesions caused by Leishmania major and comparatively unresponsive to meglumine antimoniate treatment.

PURPOSE: The present study investigated the possible role of Leishmania RNA virus 2 (LRV2) in the severity of dermal lesions and treatment failure due to Leishmania major. METHODS: The drug susceptibility of 14 clinical isolates of L.major, including resistant (n = 7) and sensitive (n = 7) isolates, was checked in the J774A.1 macrophage cell line. The presence of LRV2 among isolates was investigated by the RdRp gene and semi-nested PCR. Moreover, 1 × 106 sensitive L. major LRV2+ and LRV2- promastigotes were inoculated subcutaneously into the base tails of the 40 BALB/c mice divided into 4 groups (n = 10 in each group), including clinical LRV2+, clinical LRV2-, positive control LRV2+ and negative control LRV2-. The groups were infected with a unique isolate. The lesion size and parasite burden were evaluated. RESULTS: Sensitive and resistant isolates were determined by the drug susceptibility method. A higher presence of LRV2 was observed among MA-resistant isolates (6/7) compared with susceptible isolates (4/7), which was not statistically significant (P = 0.237). On the other hand, a comparison of the lesion sizes between the LRV2+ and LRV2- BALB/c mice groups revealed that the mean size of the lesion in the LRV2+ groups was significantly higher than the LRV2- (P = 0.034). In the same direction, there was an increased parasite burden in mice inoculated with LRV2+ groups compared with the LRV2- BALB/c mice groups (P = 0.002). CONCLUSIONS: Our findings showed that the presence of LRV2 could be one of the factors contributing to exacerbating CL. Although we found a higher presence of LRV2 in the resistant isolates, it seems that further investigations are recommended to determine the detailed association between lesions' aggravation and being comparatively unresponsive to treatment.

How mothers of a child with type 1 diabetes cope with the burden of care: a qualitative study.

INTRODUCTION: Caregiver burden is a complex construct that depends heavily on the context and culture of the community in which care takes place. This study aimed to explore the lived experience of being mothers of a child with type 1 diabetes aged 6 to 18 years. MATERIALS AND METHODS: We used a qualitative methodology utilizing conventional content analysis. We conducted 24 interviews with 20 mothers who had a child with type 1 diabetes aged 6 to 17 years. RESULTS: The mean age of mothers and children were 36.3 and 12.3 years, respectively. The mean of years with the disease was 4.3 years. Thirteen children were girls. The essential theme was coping with the burden of care through personalized coping and active acquisition of social support. The main theme consists of four sub-themes including Crisis in the family and burden of care, Losing the family equilibrium, Personalized coping strategies, and Active acquisition of social support. Mothers used personalized strategies and every support they could get to reach their aim. CONCLUSIONS: Families of children with type 1 diabetes need extensive and personalized care plans.
