These studies did reinforce the evidence that patients reporting PTLDS symptoms have a severe impairment in overall physical health and quality of life. However, prolonged antibiotic therapy showed no benefit when compared with groups who received placebo. In another study, published in , researchers examined the effect of 28 days of intravenous antibiotic compared with placebo in 55 patients reporting persistent, severe fatigue at least six months following treatment for laboratory-diagnosed Lyme disease.
In that study, people receiving antibiotics did report a greater improvement in fatigue than those on placebo. However, no benefit to cognitive function was observed. In addition, six of the study participants had serious adverse events associated with intravenous antibiotic use, and four patients required hospitalization. Overall, the study authors concluded that additional antibiotic therapy for PTLDS was not supported by the evidence.
Researchers studied 37 individuals with well-documented Lyme disease, at least three weeks of prior intravenous antibiotics, a current positive Lyme test IgG Western blot , and self-reported memory impairment. However, healthcare practitioners should become familiar with the clinical manifestations of tick-borne diseases eg, Lyme disease, especially those practicing in endemic areas and maintain a high index of suspicion during warmer months.
Ticks can be placed in a sealed container with alcohol if they need to be transported and identified. To remove a tick, use fine-tipped forceps and wear gloves. Grasp the tick as close to the skin surface as possible, including the mouth parts, and pull upward with steady, even traction.
Do not twist or jerk the tick because this may cause the mouth parts to break off and remain in the skin; however, note that the mouth parts themselves are not infectious. When removing, wear gloves to avoid possible infection. This patient's erythema migrans rash demonstrates several key features of the rash, including size, location, and presence of a central punctum, which can be seen right at the lateral margin of the inferior gluteal fold.
Note that the color is uniform; this pattern probably is more common than the classic pattern of central clearing. On history, this patient was found to live in an endemic area for ticks and to pull ticks off her dog daily.
Erythema migrans, the characteristic rash of early Lyme disease. The thorax and torso are typical locations for erythema migrans. The lesion is slightly darker in the center, a common variation. In addition, this patient worked outdoors in a highly endemic area. Physical examination also revealed a right axillary lymph node. Photo of the left side of the neck of a patient who had pulled a tick from this region 7 days previously.
Note the raised vesicular center, which is a variant of erythema migrans. The patient had a Jarisch-Herxheimer reaction approximately 18 hours after the first dose of doxycycline. Classic target lesion with concentric rings of erythema, which often show central clearing. This pattern is more common in Europe. Typical appearance of erythema migrans, the bull's-eye rash of Lyme disease.

The size and location are typical of erythema migrans, as is the history of the patient vacationing on Fire Island, NY, in the month of August. No tick bite had been noted at this location. Courtesy of Dr John Hanrahan. He then presented to the emergency department with the rashes seen in this photo. The patient had no fever and only mild systemic symptoms.
He was treated with a 3-week course of oral antibiotics. The rash on the ankle seen in this photo is consistent with both cellulitis deep red hue, acral location, mild tenderness and erythema migrans presentation in July, in an area highly endemic for Lyme disease. In this situation, treatment with a drug that covers both diseases eg, cefuroxime or amoxicillin-clavulanate is an effective strategy.
Borrelial lymphocytoma of the earlobe, which shows a bluish red discoloration. The location is typical in children, as opposed to the nipple in adults. This manifestation of Lyme disease is uncommon and occurs only in Europe. A rarely reported noninfectious complication for tick bites is alopecia.
It can begin within a week of tick removal and typically occurs in a 3- to 4-cm circle around a tick bite on the scalp. A moth-eaten alopecia of the scalp caused by bites of Dermacentor variabilis the American dog tick has also been described. No particular species appears more likely to cause alopecia. Hair regrowth typically occurs within months, although permanent alopecia has been observed. Acrodermatitis chronica atrophicans is found almost exclusively in European patients and comprises an early inflammatory phase and a later atrophic phase.
As the term suggests, the lesion occurs acrally and ultimately results in skin described as being like cigarette paper. The ideal antibiotics, route of administration and duration of treatment for persistent Lyme disease are not established. No single antibiotic or combination of antibiotics appears to be capable of completely eradicating the infection, and treatment failures or relapses are reported with all current regimens, although they are less common with early aggressive treatment. All medical treatments have risks associated with them.
While the safety profile of antibiotics is generally quite good, only the patient in consultation with his or her physician can determine whether the risks outweigh the potential benefits of any medical treatment. An ILADS doctor may consider the possibility of tick-borne coinfections, particularly if a patient does not respond to treatment or relapses when treatment is terminated. Other factors to consider are immune dysfunction caused by Lyme; silent, opportunistic infections enabled by the immune dysfunction; hormonal imbalance caused by Lyme; and other complications.
Considerations while on treatment Antibiotics can wipe out beneficial intestinal flora, leading to a wide variety of additional health problems.
Other antibiotics that have activity against borrelia include the penicillin-like antibiotic amoxicillin and the cephalosporin Ceftin. In children under the age of 12, amoxicillin is used because of the possible side effects of doxycycline in small children.
The mainstay of treatment is with oral pill antibiotics, but intravenous antibiotics are sometimes indicated for more difficult to treat cases such as meningitis, late Lyme arthritis, or neurologic-Lyme disease. Why are antibiotics the first line of treatment for Lyme disease? The use of antibiotics is critical for treating Lyme disease. Without antibiotic treatment, the Lyme bacteria can evade the host immune system and persist in the body for long periods of time.
Antibiotics go into the bacteria preferentially and either stop the multiplication of the bacteria doxycycline or disrupt the cell wall of the bacteria and kill the bacteria penicillins. By stopping the growth or killing the bacteria the host immune response is given a leg up to eradicate the residual infection.
Without antibiotics, the infection in Lyme disease can more readily persist and disseminate. What are the side effects of Lyme disease treatments? Antibiotics, like all medications, have the potential for side effects.
Role of psychiatric comorbidity in treating Lyme disease. These patients effective show no evidence of active infection and may be diagnosed with post-treatment Lyme disease syndrome PTLDS. The soft-bodied tick of the genus Ornithodoros transmits various Borrelia species that cause relapsing fever. Duration of antibiotic therapy for amoxicillin Lyme disease. Image courtesy of Dirk M. Smith R, Takkinen J. This manifestation of Lyme disease is uncommon and occurs only in Europe. Late or Chronic Lyme Experts agree that the earlier you are treated the lyme, since early disease is often successful. December 1, ; Accessed:
