[PMID: 34816041 PMCID: PMC8593464 DOI: 10.1016/j.heliyon.2021.e08347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 08/17/2021] [Accepted: 11/05/2021] [Indexed: 11/17/2022] Open
Abstract
Understanding the structure of dog population and the evaluation of the accessibility of dogs to vaccination is essential to succeed in the fight against dog rabies and to adapt the strategy of its control. We studied the characteristics of the unowned and owned dogs using the beck method during a rabies vaccination campaign in randomly selected sectors (urban and rural sites) in the North West of Tunisia. During a door-to-door investigation of households, data on owned dogs were collected to describe the owned population dog. A photographic-recapture method was used to characterize and estimate the size of the unowned dogs. A total of 1432 households accounting for 5403 inhabitants were interviewed during the survey (1298 (90.6%) in the urban site and 134 (9.3%) in the rural site). The dog-owning households were significantly higher in the rural site (76.1% (102/134)) compared to the urban site (17.8% (231/1298)) (P < 0.000000). Of the 17.8% dog-owning households in urban site, 58.4% owned one dog and 9% between 4 and 8 dogs. While, of the 76.1% dog-owning households in rural site, 24.5% owned one dog and 32.3% owned between 4 and 10 dogs. The dog: human ratio was 1:11 in the urban site and 1:1.6 in the rural site. The dog population density was estimated at 16 dogs/km2 and 4 dogs/km2 in the urban and rural sites, respectively. The confinement practices varied significantly among the urban and rural sites (P < 0.000000). The percentage of free-roaming owned dogs was 51.1% in the rural site and 31.4% in the urban site. More than 60.0% of the owned dogs in the urban site were confined. The majority of dogs in the rural site were born in the house, although, a high percentage (56.7%) of owned dogs in the urban site was adopted from neighbours, others sectors, or countries. The vaccination coverage findings indicated that 77.8% and 84.2% of the owned dog were vaccinated in the urban and rural sites, respectively. The estimated size of the free-roaming dogs was 72 dogs in the urban site (Kalaat Senan) and 16 dogs in the rural site (Sod el Khir).

The mutational spectrum of hunter syndrome reveals correlation between biochemical and clinical profiles in Tunisian patients. BMC MEDICAL GENETICS 2020; 21:111. [PMID: 32448126 PMCID: PMC7247178 DOI: 10.1186/s12881-020-01051-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Accepted: 05/14/2020] [Indexed: 11/10/2022]
Abstract
Background Mucopolysaccharidosis type II (MPS II) or Hunter syndrome is an X-linked recessive lysosomal storage disorder resulting from deficient activity of iduronate 2-sulfatase (IDS) and the progressive lysosomal accumulation of sulfated glycosaminoglycans (GAGs). Methods A diagnosis of MPS II or Hunter syndrome was performed based on the following approach after a clinical and paraclinical suspicion. Two biochemical and molecular tests were carried out separately and according to the availability of the biological material. Results All patients in this cohort presented the most common MPS II clinical features. Electrophoresis of GAGs on a cellulose acetate plate in the presence of a high concentration of heparane sulfate showed an abnormal dermatan sulfate band in the patients compared with that in a control case. Furthermore, leukocyte IDS activity ranged from 0.00 to 0.75 nmol/h/mg of leukocyte protein in patients. Five previously reported mutations were identified in this study patients: one splice site mutation, c.240 + 1G > A; two missense mutations, p.R88P and p.G94D; a large deletion of exon 1 to exon 7; and one nonsense mutation, p.Q396*. In addition, two novel alterations were identified in the MPS II patients: one frame shift mutation, p.D450Nfs*95 and one nonsense mutation, p.Q204*. Additionally, five known IDS polymorphisms were identified in the patients: c.419–16 delT, c.641C > T (p.T214M), c.438 C > T (p.T146T), c.709-87G > A, and c.1006 + 38 T > C. Conclusions The high level of urine GAGs and the deficiency of iduronate 2-sulfatase activity was associated with the phenotype expression of Hunter syndrome. Molecular testing was useful for the patients’ phenotypic classification and the detection of carriers.

Burden of cytomegalovirus disease in allogeneic hematopoietic cell transplant recipients: a national, matched cohort study in an inpatient setting. Curr Res Transl Med 2018; 66:95-101. [PMID: 30274738 DOI: 10.1016/j.retram.2018.08.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2018] [Revised: 08/07/2018] [Accepted: 08/21/2018] [Indexed: 11/17/2022]
Abstract
PURPOSE OF THE STUDY No studies have compared the risk of mortality or graft-versus-host disease, in an inpatient setting in France, in allogeneic hematopoietic cell transplant recipients who develop cytomegalovirus disease with those who do not. This study assessed the impact of cytomegalovirus disease on clinical outcomes and healthcare resource utilization in allogeneic hematopoietic cell transplant recipients using the French Programme de Médicalisation des Systèmes d'Information database. PATIENTS AND METHODS Recipients who had undergone allogeneic hematopoietic cell transplant in French hospitals between 2008 and 2011 were included in this retrospective, matched cohort study. Those with cytomegalovirus disease were each matched with two allogeneic hematopoietic cell transplant recipients without cytomegalovirus disease according to demographic and clinical characteristics. Probabilities of in-hospital mortality, graft rejection and/or graft-versus-host disease, and healthcare resource utilization were compared up to 12 months after cytomegalovirus disease diagnosis. RESULTS Overall, 4884 transplant recipients were enrolled, of which 194 had cytomegalovirus disease. Of these, 165 recipients with cytomegalovirus disease were matched to 330 without cytomegalovirus disease (1:2 ratio). The development of cytomegalovirus disease was associated with a significantly higher risk of in-hospital mortality (relative risk = 1.7, p = 0.0005) and higher cumulative number of inpatient days (p < 0.0001), but was not associated with a significantly higher risk of graft rejection and/or graft-versus-host disease or healthcare costs. CONCLUSIONS Due to the increased risk of in-hospital mortality and higher cumulative number of inpatient days in allogeneic hematopoietic cell transplant recipients with cytomegalovirus disease versus those without, new strategies to prevent and manage cytomegalovirus disease are warranted.

Abstract
The study investigated if markers of muscle injury and antioxidant status were affected by a Wingate test performed at 2 different times of day. 15 young male footballers performed 2 tests (randomized) at 07:00-h and 17:00-h. Fasting blood samples were collected before and 3 min after each test for assessment of markers of muscle injury and antioxidant status. Resting oral temperature was recorded during each session. Peak power (10.76 ± 1.05 vs. 11.15 ± 0.83 W.kg( - 1)) and fatigue index (0.41 ± 0.04 vs. 0.49 ± 0.13%) during the Wingate test, and core temperature, were significantly higher (all p<0.05) in the evening. Markers of muscle injury were significantly higher in the evening before and after exercise (e. g., 148.7 ± 67.05 vs. 195 ± 74.6 and 191.6 ± 79.52 vs. 263.6 ± 96.06 IU.L (- 1), respectively, for creatine kinase; both p<0.001). Antioxidant parameters increased after the Wingate test but only resting values were significantly higher in the morning (e. g., 1.33 ± 0.19 vs. 1.19 ± 0.14 µmol.L (- 1) for total antioxidant status; p<0.05). The results indicate that muscle injury and antioxidant activity after the Wingate test were higher in the evening, suggesting a possible link between the biochemical measures and the diurnal fluctuation of anaerobic performance. However, repetition of this study after prescribed rather than self-selected exercise intensity is recommended.

Abstract
Gaucher disease is one of the most prevalent lysosomal disorders. In this present study, we report a diagnostic strategy of type 1 Gaucher disease. The application of combined methods in molecular biology allowed us to analyse the p.Asn 370 Ser mutation. The affected individual activity is very low. First, we have to used the enzymatic digestion method. Then, we have to identified the mutation by the refractory mutation system technique using specific primers for the p.Asn 370 Ser mutation. These analyses are supplemented by the direct sequencing in order to seek and confirm this mutation. Finally, the absence of the 55 pb deletion in exon 9 among corroborated the presence of the homozygous genotype of this p.Asn 370 Ser in the patient DNA.

Abstract
Our study was carried out at a family from the Sahel (Tunisia). The father (index case) and his two children (son and daughter). The father beta-glucocerebrosidase (GCB) activity showing a deficit. These biochemical analyses are supplemented by molecular studies: enzymatic digestion and the direct sequencing. Two mutations were analysed, the p.Asn 370 Ser and the p.Leu 444 Pro. The DNA sequencing confirmed the presence of the homozygous genotype of this p.Asn 370 Ser in the father DNA and the heterozygous one in the two children DNA. It has no detection of the 55 pb deletion in exon 9 among all the specimens of DNA treated. The mutation p.Asn 370 Ser is associated with Gaucher disease type 1 correlated of a total absence of neurological involvements.

Abstract
UNLABELLED Mucopolysaccharidosis type I (MPS I) is a lysosomal disease due to mutations in the gene encoding alpha-l-iduronidase (IDUA) leading to variable clinical phenotypes with progressive severe organomegaly, bone and neurological involvement in the most severe forms. The aim of our study was to propose in Tunisia a strategy of molecular and prenatal diagnosis of the MPS I. POPULATION AND METHODS Our study was carried out on 8 MPS I patients recruited from different Tunisian regions and issued from 5 unrelated families. All the patients were offspring of consanguineous marriages. RESULTS The clinical and biological study led to diagnose 5 Hurler patients and 3 Hurler-Scheie patients. Three IDUA mutations were identified by molecular analysis within 6 different families: a novel mutation p.F602X and 2 already described mutations p.P533R and p.R628X. DISCUSSION MPS I is a heterogeneous disease characterized by variability of the phenotypes. The missense mutation p.P533R associated with the intermediate phenotype was the most frequent in the Tunisian but also in the Moroccan population. In Tunisia, the incidence of p.P533R mutation seems to be associated with the high frequency of consanguineous marriages. CONCLUSION The identification of known MPS I mutations (p.P533R and p.R628X) and of the novel mutation p.F602X permits reliable genetic counselling of at-risk relatives and molecular prenatal diagnosis.

Abstract
A Tunisian patient affected by mucopolysaccharidosis (MPS) was investigated for a biological analysis (quantitative and qualitative glycosaminoglycans (GAG) screening). We have also done an enzymatic determination of alpha-L-iduronidase activity (IDUA). The most common mutation (p.Gln 70 X, p.Trp 402X and p.Pro 533 Arg) were researched by an enzymatic restriction and sequencing of the IDUA gene. Enzymatic and urinary diagnostics suggested a MPS I phenotype. The patient investigated had the mutation p.Pro 533 Arg in the homozygous status, whereas his parents were heterozygous for this mutation.

Abstract
Mucopolysaccharidosis IVA (MPS IVA; Morquio A disease) is an autosomal recessive lysosomal storage disorder caused by a genetic deficiency of the N-acetylgalactosamine-6-sulfate sulfatase (GALNS; E.C.3.1.6.4). GALNS is required to degrade keratan sulfate (KS) and chondroitine-6-sulfate (C6S). The accumulation of undegraded substrates in lysosomes of the affected tissues leads to a systemic bone dysplasia. Total urine glycosaminoglycans (GAG) in patients with MPS IVA are close to the normal range so it is difficult to distinguish this disease based on urine GAG excretion. Another potential disease marker could be KS levels in urine and plasma. Although the enzymatic diagnosis of affected patients with MPS IVA can be made, the detection of obligate heterozygotes by enzymatic measurement is less reliable because of a marked overlap of GALNS in fibroblasts or leucocytes from affected phenotype and normal controls. The genetic heterozygoty of MPS IVA has been facilitated by the isolation and characterization of the full lengh cDNA encoding human GALNS. Conventional therapy is symptomatic and limited to palliative procedures, which have virtually no impact upon mortality. To date, there is still no general consensus about the effectiveness of bone marrow transplantation. In the future, gene therapy could represent a great therapeutic improvement.

Abstract
Mucopolysaccharidosis type IV A (MPS IV A) is an autosomal recessive disorder resulting from the deficient activity of the lysosomal enzyme, N-acetylgalactosamine-6-sulfate sulfatase (GALNS) and the progressive lysosomal accumulation of keratane sulfate. Clinically, the MPS IV A differs from the other MPS by the localisation of the keratane sulfate in skelet and in eyes associated to the conservation of a normal intelligence. To date, the characterization and purification of the GALNS gene made a research for pathogenic mutations in patients with MPS IV A easier. These mutations are responsible of severe, intermediate or mild phenotype. The aim for this work was the research of clinical, biologic and molecular characteristics of two Tunisian MPS IV A patients who were offsprings of consanguineous mating. Enzymatic and urinary diagnostics suggested a MPS IV A phenotype. A novel homozygous mutation IVS1+1G-A was identified by direct sequencing in the GALNS gene of the two patients. Identification of GALNS mutations provide genotype/phenotype correlations and permit the precision of anomalies responsible of Morquio A phenotype in concerned families.

Abstract
Mucopolysaccharidosis type IVA (MPS IVA; OMIM #253000) or Morquio A syndrome is an autosomal recessive inborn error resulting from the deficient activity of the lysosomal enzyme, N-acetylgalactosamine-6-sulfatase (GALNS), and the progressive lysosomal accumulation of sulfated glycosaminoglycans. Clinically, the severe form of this lysosomal storage disease is characterized by a characteristic severe bone dysplasia and normal intelligence. To date, a variety of mutations have been associated with the severe MPS IVA phenotype. Here, we report the GALNS mutations in six severe MPS IVA patients from four unrelated Tunisian families. For mutation detection, each of the 14 exons and adjacent intron-exon junctions of the GALNS gene were sequenced after PCR-amplification from genomic DNA. Two novel mutations were identified: a G to A transition in the conserved 5' donor splice site of intron 1 (GACgt-->GACat: designated IVS1(+1g-->a)) and a G to C transversion in codon 66 of exon 2 predicting a glycine to arginine substitution (G66R). The IVS1(+1g-->a) mutation was homozygous in five similarly affected patients from three presumably unrelated families, but haplotype analysis suggested a common ancestor. The affected patient in the fourth family was homozygous for the G66R mutation. These are the first GALNS mutations causing severe MPS IVA disease identified in Tunisia. These molecular findings provide genotype/phenotype correlations, and permit accurate carrier detection, prenatal diagnosis, and counseling for MPS IVA disease in Tunisia where first cousin consanguineous mating remains frequent.

Abstract
Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disease resulting from the defective activity of the enzyme alpha-L-iduronidase (IDUA). The disease has severe and milder phenotypic subtypes. The IDUA mutations in five MPS I patients from three unrelated families from central and southern Tunisia were determined by amplifying and sequencing each of the IDUA exons and intron-exon junctions. Two novel IDUA mutations, c.1805delTinsGAACA in exon 13 and I270S in exon 7, and two previously reported mutations, P533R and R628X, were detected. The two patients in family 1 who had the Hurler phenotype were homoallelic for the novel deletion-insertion mutation. The patient in family 2 who also had the Hurler phenotype was heteroallelic for the novel missense mutation I270S and the previously reported nonsense mutation R628X. The two patients in family 3 who had the Hurler-Scheie phenotype were homoallelic for P533R. In addition, six known IDUA polymorphisms were identified. These are the first Tunisian MPS I patients to be genotyped. The identification of these mutations and their genotype-phenotype correlations should facilitate prenatal diagnosis and counselling for MPS I in Tunisia, where a very high rate of consanguinity exists.

Abstract
BACKGROUND Lipid and glycemic imbalances are frequent disorders found in diabetes type 2. These disorders are influenced by dietary means. AIM to investigate saturated fatty acids (SFA), polyunsaturated fatty acids (PUFS) and oleic acid of cholesterol ester fraction in non-insulin dependant diabetes mellitus without cardiovascular complications (NIDDM), non-insulin dependant diabetes mellitus with cardiovascular complications (NIDDMc) and healthy controls. METHODS The composition of cholesterol ester fatty acids in 35 NIDDM, 33 NIDDMc and 32 controls were measured by gas-chromatography. Glycaemia and lipid profile were measured using commercial kits. RESULTS Compared to NIDDM and to controls, NIDDMc showed a significant increase of different SFA (C12:0, C14:0, C16:0, C18:0). Oleic acid (C18:1) was significantly decreased in NIDDMc and NIDDM compared to controls (15,88 +/- 2,34 and 22,66 +/- 4,14 vs 28,18 +/- 2,90). Linoleic acid (C18:2) was significantly increased in NIDDMc compared to NIDDM and controls (52,59 +/- 5,50 vs 49,29 +/- 8,58 and 39,26 +/- 10,46). Linolenic acid (C18:3) and arachidonic acid (C20:4) were significantly decreased in NIDDMc compared to NIDDM and to controls. Linoleic acid (C18:2) / linolenic acid (C18:3) ratio was increased in NIDDMc. CONCLUSION Linoleic (C18:2) acid excess intake found in our NIDDMc could emphasize arachidonic synthesis which is directly transformed while an inflammatory syndrome observed in coronary pathologies.

Abstract
PURPOSE The frequency of chronic illness and the expenditure of medications increase with the older age. If drug-prescribing is very often beneficial for the patients, elderly subjects are particularly exposed to the side-effects of medications, and to their consequences. Although the age in itself do not generally forbid a medication, it can modify some of the objectives and the modality of the treatment. CURRENT KNOWLEDGE AND KEY POINTS Four main factors explain the growing frequency of the iatrogenic pathology in the old age: polymedication, pharmacological modifications that occur with the ageing process, lack of coordination between different prescribers, and physical and psycho-social deficiencies which are the keys for identifying the "frail elderlies". FUTURE PROSPECTS AND PROJECTS In regard to the frequent polypathological conditions of the oldest patients, one does not have to consider a sum of sicknesses, but a global situation, and one needs to replace a condition in a general context, and to establish priorities in the goals of the treatment. Appropriate drug-prescribing also needs to take account of the latest medical recommendations concerning numbers of medications, and a more frequent involving of elderly subjects in clinical trials.

Abstract
At present, the application of combined methods in molecular biology allows us to carry out the prenatal diagnosis in a more rapid and less onerous manner especially when the family presents an index case. In this study, we have analyzed a family with one case of intermediate beta-thalassemia. First, we have used the denaturing gradient gel electrophoresis (DGGE). Then, we have identified the mutations by the refractory mutation system technique (ARMS PCR) using specific primers for the most frequent mutations in the Tunisian population (codon 39 (C --> T) and IVS-I-2 (T--> G) for beta0 thalassemias and IVS-I-110 (G --> A) for beta+ thalassemias). The analyzed family has shown the IVS-I-110 (G --> A) mutation in the heterozygous state in the mother and the index case. Subsequently, sequencing in the gene revealed a frameshift 8 (-AA) mutation in the father and his daughter. This patient is thus a compound heterozygote Codon 8 (-AA)/IVS-I-110. DGGE and ARMS PCR analysis of foetal DNA extracted from trophoblast culture didn't show any of the two mutations found in the family.
