Project description:BackgroundFamilial hypokalemic periodic paralysis (FHPP) is rare, so its management is essential to report.Case presentationA 25-year-old Indonesian woman complained of feeling weak in both hands and legs, but the heaviest in both legs. The patient has several family members with similar complaints. The patient experienced decreased muscle strength in the upper extremity of 4/4 and the lower extremity of 3/3. Laboratory investigation showed potassium of 2.0 mmol/L, and the patient was given KCL of 50 mEq/24 hours, KSR of 3 × 600 mg/24 hours for 3 days, and a high potassium diet. The next few days, potassium levels increased, and the patient was treated as an outpatient.DiscussionEarly diagnosis and management of acute flaccid paralysis (AFP) due to FHPP are very effective in low-resource settings.ConclusionFinding the cause of AFP is essential for better management.

Project description:Alpha-gal syndrome (AGS) is a delayed allergic response to red meat caused by the production of alpha-gal-specific IgE following certain tick bites. We designed this study to characterize the underlying immune response to tick bites associated with AGS. Our results suggest that Amblyomma americanum bites direct mouse immunity toward Th2 following the initial burst of proinflammatory response and facilitate host sensitization to the α-gal antigen.

Project description:The global burden of snakebites is growing, particularly its nonfatal sequelae. Therefore, the World Health Organization reinstated snakebites to its list of Neglected Tropical Diseases. We describe the case of a 4.5-year-old boy who was bitten by a spitting cobra, resulting in considerable local swelling accompanied by a right-sided facial paralysis due to neurotoxicity by cobra venom. Presently, surgical methods to recover facial paralysis include nerve repair, nerve grafting, nerve transfers, static slings, muscle transfers, and functional muscle transplantations. However, mime therapy consisting of neuromuscular retraining resulted in a good functional result with a moderate contour deficiency of the right cheek and a subtle paresis of the zygomatic muscles at 1 year and 9 months follow-up. The natural history of facial paralysis in our case shows that this condition can be transient and may resolve with mime therapy as a conservative measure.

Project description:Rocky Mountain spotted fever (RMSF) and other tick-borne illnesses, a burden predominantly in the summer season, produce symptoms ranging from fever to paralysis. Although often benign, sequela can range from chronic arthritis to neurologic or cardiac illness. Especially in the areas of the North America where tick-borne illnesses are more prevalent, tick-borne illnesses require vigilance on the provider’s part to inquire about recent outdoor activity. Prevention is paramount including the use of protective clothing and tick repellent.

Project description:Tick-borne infectious diseases and allergies are a growing problem worldwide. Tick bite allergy has been associated with the direct effect of immunoglobulin E (IgE) response to tick salivary antigens, or secondary to the induction of allergy to red meat consumption through IgE antibodies against the carbohydrate α-Gal (Gal α 1-3Gal β 1-(3)4GlcNAc-R). However, despite the growing burden of this pathology, the proteins associated with anaphylaxis to tick bite have not been characterized. To address this question, a comparative proteomics approach was used to characterize tick proteins producing an IgE antibody response in a healthy individual with record of tick bites, which had not resulted in any allergic reactions, and two patients with anaphylactic reactions to Rhipicephalus bursa or Hyalomma marginatum tick bites. Both patients and the healthy individual were red meat tolerant. The results supported a patient-specific IgE antibody response to tick species responsible for the anaphylaxis to tick bite. Both patients and the healthy individual serologically recognized tick proteins with and without α-Gal modifications, with proteins differentially recognized by patients but not control sera. These proteins could be used as potential antigens for diagnostics, treatment and prevention of tick bite-induced allergies.

Project description:Ticks are blood-sucking arthropod ectoparasites of vertebrates, which are vectors of many diseases. They cause varied skin manifestations, which occur either due to the attachment of the tick to the host or due to the infections it spreads. Dermoscopy serves as a precise diagnostic tool for tick bites and also helps in ensuring complete removal of the tick. Prompt removal and identification of the tick, along with appropriate antibiotic therapy, are important aspects of the management of this condition. Herein, we present a case series of nine patients with tick bites, by ticks of similar morphology but at different body sites and with varied predisposing factors.

Project description:Ticks are important vectors of pathogens and secreted neurotoxins with approximately 69 out of 692 tick species having the ability to induce severe toxicoses in their hosts. The Australian paralysis tick (Ixodes holocyclus) is known to be one of the most virulent tick species producing a flaccid paralysis and fatalities caused by a family of neurotoxins known as holocyclotoxins (HTs). The paralysis mechanism of these toxins is temperature dependent and is thought to involve inhibition of acetylcholine levels at the neuromuscular junction. However, the target and mechanism of this inhibition remain uncharacterised. Here, we report that three members of the holocyclotoxin family; HT-1 (GenBank AY766147), HT-3 (GenBank KP096303) and HT-12 (GenBank KP963967) induce muscle paralysis by inhibiting the dependence of transmitter release on extracellular calcium. Previous study was conducted using extracts from tick salivary glands, while the present study is the first to use pure toxins from I. holocyclus. Our findings provide greater insight into the mechanisms by which these toxins act to induce paralysis.

Project description:IntroductionTicks are the most important obligate blood-feeding vectors of human pathogens. With the advance of high-throughput sequencing, more and more bacterial community and virome in tick has been reported, which seems to pose a great threat to people.MethodsA total of 14 skin specimens collected from tick-bite patients with mild to severe symptoms were analyzed through meta-transcriptomic sequencings.ResultsFour bacteria genera were both detected in the skins and ticks, including Pseudomonas, Acinetobacter, Corynebacterium and Propionibacterium, and three tick-associated viruses, Jingmen tick virus (JMTV), Bole tick virus 4 (BLTV4) and Deer tick mononegavirales-like virus (DTMV) were identified in the skin samples. Except of known pathogens such as pathogenic rickettsia, Coxiella burnetii and JMTV, we suggest Roseomonas cervicalis and BLTV4 as potential new agents amplified in the skins and then disseminated into the blood. As early as 1 day after a tick-bite, these pathogens can transmit to skins and at most four ones can co-infect in skins.DiscussionAdvances in sequencing technologies have revealed that the diversity of tick microbiome and virome goes far beyond our previous understanding. This report not only identifies three new potential pathogens in humans but also shows that the skin barrier is vital in preventing horizontal transmissions of tick-associated bacteria or virus communities to the host. It is the first research on patients' skin infectome after a tick bite and demonstrates that more attention should be paid to the cutaneous response to prevent tick-borne illness.

Project description:A confirmed case of rickettsiosis acquired in South Africa and recognized in Poland was described. The patient fulfilled clinical criteria highly suggestive of African tick bite fever, such as eschars, regional lymphadenitis, cutaneous rash within 10 days after his return from sub-Saharan Africa. Infection with Rickettsia africae was confirmed by polymerase chain reaction and sequencing.
