Once in the hospital, the antibiotics of choice are usually IV broad spectrum 3rd generation cephalosporins, e.g., cefotaxime or ceftriaxone. Benzylpenicillin and chloramphenicol are also effective. Supportive measures include IV fluids, oxygen, inotropic support, e.g., dopamine or dobutamine and management of raised intracranial pressure. Steroid therapy may help in some adult patients, but is unlikely to affect long term outcomes.There is some debate on which antibiotic is most effective at treating the illness. A systematic review compared two antibiotics. There was one trial: an open label (not blinded) non-inferiority trial of 510 people comparing two different types of antibiotics; ceftriaxone (in which there were 14 deaths out of 247), and chloramphenicol (12 deaths out of 256). There were no reported side effects. Both antibiotics were considered equally effective. Antibiotic choice should be based on local antibiotic resistance information. Prognosis
Complications
Complications following meningococcal disease can be divided into early and late groups. Early complications include: raised intracranial pressure, disseminated intravascular coagulation, seizures, circulatory collapse and organ failure. Later complications are: deafness, blindness, lasting neurological deficits, reduced IQ, and gangrene leading to amputations. Epidemiology
Africa
The importance of meningitis disease is as significant in Africa as HIV, TB and malaria. Cases of meningococcemia leading to severe meningoencephalitis are common among young children and the elderly. Deaths occurring in less than 24 hours are more likely during the disease epidemic seasons in Africa and Sub-Saharan Africa is hit by meningitis disease outbreaks throughout the epidemic season.
Diagnosis
MTHFR deficiency is diagnosed by genetic testing. Management
In common forms of MTHFR deficiency, elevated plasma homocysteine levels have sometimes been treated with Vitamin B12 and low doses of folic acid. Although this treatment significantly decreases the serum levels of homocysteine, this treatment is not thought to improve health outcomes.Due to the ineffectiveness of these treatments, it was no longer considered clinically useful to test for MTHFR in most cases of thrombophilia or recurrent pregnancy loss. A more recent evaluation from a case series recommends testing for MTHFR in case of long lasting impaired fertility and repeat miscarriages. Treatment with high doses of folic acid (5 mg/day) are deemed unsuitable for MTHFR isoform carriers, who could alternatively be treated with the metabolically active form, 5-methyltetrahydrofolate. 5-MTHF was shown to induce significantly higher plasma folate concentrations compared to folic acid in homozygous MTHFR mutation carriers in this case series.A different study corroborates these results and suggests a physiological dose (800 μg) of 5-methyltetrahydrofolate can bypass MTHFR C677T and A1298C isoforms in couples with fertility problems. This treatment with 5-MTHF also avoids un-metabolized folic acid syndrome, which can occur with folic acid intakes of 5 mg per day. Prognosis
Whether MTHFR deficiency has any effect at all on all-cause mortality is unclear. One Dutch study showed that the MTHFR mutation was more prevalent in younger individuals (36% relative to 30%), and found that elderly men with MTHFR had an elevated mortality rate, attributable to cancer. Among women, however, no difference in life expectancy was seen.
