The Jarisch-Herxheimer reaction, which is the response to the body after endotoxins are released by the death of harmful organisms in the human body, starts usually during the first day of antibiotic treatment. The reaction increases the person's body temperature, decreases the overall blood pressure (both systolic and diastolic levels), and results in leukopenia and rigors in the body. This reaction can occur during any treatment of spirochete diseases.

It is important to realize that syphilis can recur. An individual who has had the disease once, even if it has been treated, does not prevent the person from experiencing recurrence of syphilis. Individuals can be re-infected, and because syphilis sores can be hidden, it may not be obvious that the individual is infected with syphilis. In these cases, it is vital to become tested and treated immediately to reduce spread of the infection.

One of the potential side effects of treatment is the Jarisch-Herxheimer reaction. It frequently starts within one hour and lasts for 24 hours, with symptoms of fever, muscle pains, headache, and a fast heart rate. It is caused by cytokines released by the immune system in response to lipoproteins released from rupturing syphilis bacteria.

For neurosyphilis, due to the poor penetration of benzylpenicillin into the central nervous system, those affected are recommended to be given large doses of intravenous penicillin for a minimum of 10 days. If a person is allergic, ceftriaxone may be used or penicillin desensitization attempted. Other late presentations may be treated with once-weekly intramuscular benzylpenicillin for three weeks. If allergic, as in the case of early disease, doxycycline or tetracycline may be used, albeit for a longer duration. Treatment at this stage limits further progression but has only slight effect on damage which has already occurred.

The most popular treatment forms for any type of syphilis uses penicillin, which has been an effective treatment used since the 1940s.

Other forms also include Benzathine penicillin, which is usually used for primary and secondary syphilis (it has no resistance to penicillin however). Benzathine penicillin is used for long acting form, and if conditions worsen, penicillin G is used for late syphilis.

The CDC recommendation for chancroid is a single oral dose (1 gram) of azithromycin, or a single IM dose of ceftriaxone, or oral erythromycin for seven days.

Abscesses are drained.

"H. ducreyi" is resistant to sulfonamides, tetracyclines, penicillins, chloramphenicol, ciprofloxacin, ofloxacin, trimethoprim and aminoglycosides. Recently, several erythromycin resistant isolates have been reported.

Treatment failure is possible with HIV co-infection and extended therapy is sometimes required.

Penicillin is used to treat neurosyphilis; however, early diagnosis and treatment is critical. Two examples of penicillin therapies include:

- Aqueous penicillin G 3–4 million units every four hours for 10 to 14 days.

- One daily intramuscular injection and oral probenecid four times daily, both for 10 to 14 days.

Follow-up blood tests are generally performed at 3, 6, 12, 24, and 36 months to make sure the infection is gone. Lumbar punctures for CSF fluid analysis are generally performed every 6 months.

Neurosyphilis was almost at the point being unheard of in the United States after penicillin therapy was introduced. However, concurrent infection of "T. pallidum" with human immunodeficiency virus (HIV) has been found to affect the course of syphilis. Syphilis can lie dormant for 10 to 20 years before progressing to neurosyphilis, but HIV may accelerate the rate of the progress. Also, infection with HIV has been found to cause penicillin therapy to fail more often. Therefore, neurosyphilis has once again been prevalent in societies with high HIV rates and limited access to penicillin. Blood testing for syphilis was once required in order to obtain a marriage license in most U.S. states, but that requirement has been discontinued by all 50 states over recent years, also contributing to the spread of the disease.

Prognosis is excellent with proper treatment. Treating sexual contacts of affected individual helps break cycle of infection.

Treatment protocol is not well established. Some sources report that approximately half of the patients will fully recover after lengthy (mean time 14.5 months, range 2–24 months) expectant management.

Treatment with steroids is lengthy and usually requires about 6 months. While some source report very good success with steroids most report a considerable risk of recurrence after a treatment with steroids alone. Steroids are known to cause elevation of prolactin levels and increase risk of several conditions such as diabetes, and other endocrinopathies which in turn increase the risk of IGM. Treatment with topical steroids to limit side effects was also reported in one case. For surgical treatment recurrence rates of 5-50% have been reported.

A 1997 literature review article recommended complete resection or corticosteroid therapy, stating also that long-term follow-up was indicated due to a high rate of recurrence.

Treatment with a combination of glucocorticoids and prolactin lowering medications such as bromocriptine or cabergoline was used with good success in Germany. Prolactin lowering medication has also been reported to reduce the risk of recurrence. In cases of drug-induced hyperprolactinemia (such as antipsychotics) prolactin-sparing medication can be tried.

Methotrexate alone or in combination with steroids has been used with good success. Its principal mechanism of action is immunomodulating activity, with a side effect profile that is more favorable for treating IGM.

Colchicine, azathioprine and NSAIDs have also been used.

PFAPA syndrome typically resolves spontaneously. Treatment options are used to lessen the severity of episodes. Treatment is either medical or surgical.

One treatment often used is a dose of a corticosteroid at the beginning of each fever episode. A single dose usually ends the fever within several hours. However, in some children, they can cause the fever episodes to occur more frequently. Interleukin-1 inhibition appears to be effective in treating this condition.

Surgical removal of the tonsils appears to be beneficial compared to no surgery in symptom resolution and number of future episodes. The evidence to support surgery is; however, of moderate quality.

If a pregnant mother is identified as being infected with syphilis, treatment can effectively prevent congenital syphilis from developing in the fetus, especially if he or she is treated before the sixteenth week of pregnancy. The fetus is at greatest risk of contracting syphilis when the mother is in the early stages of infection, but the disease can be passed at any point during pregnancy, even during delivery (if the child had not already contracted it). A woman in the secondary stage of syphilis decreases her fetus's risk of developing congenital syphilis by 98% if she receives treatment before the last month of pregnancy. An afflicted child can be treated using antibiotics much like an adult; however, any developmental symptoms are likely to be permanent.

Kassowitz’s law is an empirical observation used in context of congenital syphilis stating that the greater the duration between the infection of the mother and conception, the better is the outcome for the infant. Features of a better outcome include less chance of stillbirth and of developing congenital syphilis.

The Centers for Disease Control and Prevention recommends treating symptomatic or babies born to infected mother with unknown treatment status with procaine penicillin G, 50,000 U/kg dose IM a day in a single dose for 10 days. Treatment for these babies can vary on a case by case basis. Treatment cannot reverse any deformities, brain, or permanent tissue damage that has already occurred.

The disease can be treated with penicillin, tetracycline (not to be used in pregnant women), azithromycin or chloramphenicol, and can be prevented through contact tracing by public health officials. A single intramuscular injection of long-acting penicillin is effective against endemic treponematoses including pinta, yaws, and bejel

In the case of rape, the person can be treated prophylacticly with antibiotics.

An option for treating partners of patients (index cases) diagnosed with chlamydia or gonorrhea is patient-delivered partner therapy, which is the clinical practice of treating the sex partners of index cases by providing prescriptions or medications to the patient to take to his/her partner without the health care provider first examining the partner.

Treatment is normally by a single intramuscular injection of penicillin, or by a course of penicillin, erythromycin or tetracycline tablets. A single oral dose of azithromycin was shown to be as effective as intramuscular penicillin. Primary and secondary stage lesions may heal completely, but the destructive changes of tertiary yaws are largely irreversible.

The first-line treatment for arteritis is oral glucocorticoid (steroid) medication, such as prednisone, taken daily for a period of three months. After this initial phase, the medication may be reduced in dose or frequency, e.g. every other day, if possible. If the disease worsens with the new treatment schedule, a cytotoxic medication may be given, in addition to the glucocorticoid. Commonly used cytotoxic agents include azathioprine, methotrexate, or cyclophosphamide. The dose of glucocorticoid medication may be decreased if response to treatment is good. This medication may be reduced gradually once the disease becomes inactive, slowly tapering the dose (to allow the body time to adjust) until the medication may be stopped completely. Conversely, if the disease remains active, the medication will need to be increased. After six months, if the medication cannot be reduced in frequency to alternate days, or if in 12 months the medications cannot be stopped completely, then treatment is deemed to have failed.

Pulsed therapy is an alternative method of administering the medications above, using much higher doses over a short period of time (a pulse), to reduce the inflammation within the arteries. Methylprednisolone, a glucocorticoid, is often used for pulse therapy; cyclophosphamide is an alternative. This method has been shown to be successful for some patients. Immunosuppressive pulse therapy, such as with cyclophosphamide, has also demonstrated relief of symptoms associated with arteritis.

It is treatable with penicillin or other antibiotics, resulting in a complete recovery.

Since each case is different, the following are possible treatments that patients might receive in the management of myelitis.

- Intravenous steroids

High-dose intravenous methyl-prednisolone for 3–5 days is considered as a standard of care for patients suspected to have acute myelitis, unless there are compelling reasons otherwise. The decision to offer continued steroids or add a new treatment is often based on the clinical course and MRI appearance at the end of 5 days of steroids.

- Plasma exchange (PLEX)

Patients with moderate to aggressive forms of disease who don’t show much improvement after being treated with intravenous and oral steroids will be treated with PLEX. Retrospective studies of patients with TM treated with IV steroids followed by PLEX showed a positive outcome. It also has been shown to be effective with other autoimmune or inflammatory central nervous system disorders. Particular benefit has been shown with patients who are in the acute or subacute stage of the myelitis showing active inflammation on MRI. However, because of the risks implied by the lumbar puncture procedure, this intervention is determined by the treating physician on a case-by-case basis.

- Immunosuppressants/Immunomodulatory agents

Myelitis with no definite cause seldom recurs, but for others, myelitis may be a manifestation of other diseases that are mentioned above. In these cases, ongoing treatment with medications that modulate or suppress the immune system may be necessary. Sometimes there is no specific treatment. Either way, aggressive rehabilitation and long-term symptom management are an integral part of the healthcare plan.

Prophylaxis and treatment with an anti-inflammatory agent may stop progression of the reaction. Oral aspirin or ibuprofen every four hours for a day or 60 mg of prednisone orally or intravenously has been used as an adjunctive treatment . However, steroids are generally of no benefit. Patients must be closely monitored for the potential complications (collapse and shock) and may require IV fluids to maintain adequate blood pressure. If available, meptazinol, an opioid analgesic of the mixed agonist/antagonist type, should be administered to reduce the severity of the reaction. Anti TNF-a may also be effective.

Treatment of atrophic rhinitis can be either medical or surgical.

Medical measures include:

- Nasal irrigation using normal saline

- Nasal irrigation and removal of crusts using alkaline nasal solutions prepared by dissolving a spoonful of powder containing one part sodium bicarbonate, one part sodium biborate and two part sodium chloride.

- 25% glucose in glycerine can be applied to the nasal mucosa to inhibit the growth of proteolytic organisms which produce foul smell.

- Local antibiotics, such as chloromycetine.

- Vitamin D (Kemicetine).

- Estradiol spray for regeneration of seromucinous glands and vascularization of mucosa.

- Systemic streptomycin (1g/day) against Klebsiella organisms.

- Oral potassium iodide for liquefaction of secretion.

- Placental extract injected in the submucosa.

Surgical interventions include:

- Young's operation.

- Modified Young's operation.

- Narrowing of nasal cavities, submucosal injection of Teflon paste, section and medial displacement of the lateral wall of the nose.

- Transposition of parotid duct to maxillary sinus or nasal mucosa.

Some vertically transmitted infections, such as toxoplasmosis and syphilis, can be effectively treated with antibiotics if the mother is diagnosed early in her pregnancy. Many viral vertically transmitted infections have no effective treatment, but some, notably rubella and varicella-zoster, can be prevented by vaccinating the mother prior to pregnancy.

If the mother has active herpes simplex (as may be suggested by a pap test), delivery by Caesarean section can prevent the newborn from contact, and consequent infection, with this virus.

IgG antibody may play crucial role in prevention of intrauterine infections and extensive research is going on for developing IgG-based therapies for treatment and vaccination.

According to present research, PFAPA does not lead to other diseases and spontaneously resolves as the child gets older, with no long term physical effects.

However, PFAPA has been found in adults and may not spontaneously resolve.

A syphilid is any of the cutaneous and mucous membrane lesions characteristic of secondary and tertiary syphilis.

It appears about 10 weeks after infection. Patient may present with prodromal symptoms such as fever, acratia, myalgia athralgia, headache, anorexia. Its eruption pattern is macular, papular, follicular papules, or pustule, symmetrical, generalized and dense, round or oval in shape, and is red copper in color.

Treatment of aortitis depends on the underlying cause. Infectious causes commonly require antibiotic treatment, while those associated with autoimmune vasculitides are generally treated with steroids.

Management includes the following treatment priorities: stop the inflammation, treat complications, prevent and monitor for re-occurrence.

Treatment (which is based on supportive care) is as follows:

Pyrimethamine-based maintenance therapy is often used to treat Toxoplasmic Encephalitis (TE), which is caused by Toxoplasma gondii and can be life-threatening for people with weak immune systems. The use of highly active antiretroviral therapy (HAART), in conjunction with the established pyrimethamine-based maintenance therapy, decreases the chance of relapse in patients with HIV and TE from approximately 18% to 11%. This is a significant difference as relapse may impact the severity and prognosis of disease and result in an increase in healthcare expenditure.

Palmar erythema has no specific treatment. Management is based on the underlying cause. When its cause is treated then patients get relief. If it is attributable to a particular drug then the drug should be withdrawn.

Intravenously administered penicillin is the treatment of choice. Associated pain can be treated with opiates, valproate, or carbamazepine. Those with tabes dorsalis may also require physical therapy to deal with muscle wasting and weakness. Preventive treatment for those who come into sexual contact with an individual with syphilis is important.
