  • Note(1)Preliminary evidence demonstrates that neuraminidase inhibitor can reduce the duration of viral replication and improve survival among patients with avian influenza. In cases of suspected avian influenza, one of the following 3 neuraminidase inhibitors should be administered as soon possible, preferably within 48 hours of symptom onset.
  • Note(2)The use of corticosteroids is not recommended.
  • Note(3): Physicians may consider increasing either the recommended daily dose and/or the duration of treatment in cases of severe disease.
  • Note(4):The use of amantadine is not recommended as most H5N1 and H7N9 avian influenza viruses are resistant to it.[2]
  • Note(5):Supportive care is also an important cornerstone of the care of patients with avian influenza. Considering the severity of the illness and the possible complications, patients may require fluid resuscitation, vasopressors, intubation and ventilation, paracentesis, hemodialysis or hemofiltration, and parentral nutrition.

Malaraia

  • 1.Treatment of uncomplicated P. falciparum malaria
  • 1.1Treat children and adults with uncomplicated P. falciparum malaria (except pregnant women in their first trimester) with one of the following recommended ACT (artemisinin-based combination therapy)
  • Preferred regimen(1): Artemether 5–24 mg/kg bw PO AND Lumefantrine 29–144 mg/ kg bw PO, Both are given bid for 3 days (total, six doses). The first two doses should, ideally, be given 8 h apart.
  • Dosage regimen based on Body weight (kg)
  • Preferred regimen(2):Artesunate (2–10) mg/kg bw per day AND Amodiaquine(7.5–15) mg/kg bw per day ,both are given once a day for 3 days. A total therapeutic dose range of 6–30 mg/kg bw per day artesunate and 22.5–45 mg/kg bw per dose amodiaquine is recommended
  • Dosage regimen based on Body weight (kg)
  • Preferred regimen(3): Artesunate (2–10) mg/kg bw per dayAND Mefloquine (2–10) mg/kg bw per day both are given once a day for 3 days
  • Dosage regimen based on Body weight (kg)
  • Body weight (kg)-5 to < 9- Artesunate 25 (mg) AND Mefloquine 55 (mg) given bid for 3 days;
  • Body weight (kg)-9to < 18- Artesunate 50 (mg) AND Mefloquine 110 (mg) given bid for 3 days;
  • Body weight (kg)-18 to < 36- Artesunate 100 (mg) AND Mefloquine 220 (mg) given bid for 3 days;
  • Body weight (kg)- ≥ 36 - Artesunate 200 (mg) AND Mefloquine 440 (mg) given bid for 3 days;
  • Preferred regimen(4): Artesunate (2–10) mg/kg bw per day given once a day for 3 days AND Sulfadoxine–Pyrimethamine 1.25 (25–70 / 1.25–3.5) mg/kg bw given as a single dose on day 1
  • Preferred regimen(5):Dihydroartemisinin (2–10) mg/kg bw per day AND Piperaquine(16–27) mg/kg bw per day : A target dose (range) of 4 (2–10) mg/kg bw per day dihydroartemisinin and 18 (16–27) mg/kg bw per day piperaquine given once a day for 3 days for adults and children weighing ≥ 25 kg. The target doses and ranges for children weighing < 25 kg are 4 (2.5–10) mg/kg bw per day dihydroartemisinin and 24 (20–32) mg/kg bw per day piperaquine once a day for 3 days.
  • Dosage regimen based on Body weight (kg)
  • 1.2Reducing the transmissibility of treated P. falciparum infections In low-transmission areas in patients with P. falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Preferred regimen: single dose of 0.25 mg/kg bw Primaquine with ACT
  • 2Recurrent Falciparum Malaria
  • 2.1Failure within 28 days
  • Note:The recommended second-line treatment is an alternative ACT known to be effective in the region. Adherence to 7-day treatment regimens (with artesunate or quinine both of which should be co-administered with + tetracycline, or doxycycline or clindamycin) is likely to be poor if treatment is not directly observed; these regimens are no longer generally recommended.
  • 2.2 Failure after 28 days
  • Note: all presumed treatment failures after 4 weeks of initial treatment should, from an operational standpoint, be considered new infections and be treated with the first-line ACT. However, reuse of mefloquine within 60 days of first treatment is associated with an increased risk for neuropsychiatric reactions, and an alternative ACT should be used
  • Reducing the transmissibility of treated P. falciparum infections In low-transmission areas in patients with P. falciparum malaria (except pregnant women, infants aged < 6 months and women breastfeeding infants aged < 6 months)
  • Note a single dose of 0.25 mg/kg bw Primaquine with ACT
  • 3Treating uncomplicated P. falciparum malaria in special risk groups
  • 3.1Pregnancy
  • First trimester of pregnancy :Quinine AND Clindamycin PO 10mg/kg bw bid for 7 days
  • Second and third trimesters : Mefloquine is considered safe for the treatment of malaria during the second and third

trimesters; however, it should be given only in combination with an artemisinin derivative.

  • Note:Quinine is associated with an increased risk for hypoglycaemia in late pregnancy, and it

should be used (with clindamycin) only if effective alternatives are not available.

  • Note:Primaquine and tetracyclines should not be used in pregnancy.
  • 3.2 Infants less than 5kg body weight : with an ACT at the same mg/kg bw target dose as for children weighing 5 kg.
  • 3.3Patients co-infected with HIV:
  • Note:avoid Artesunate + SP if they are also receiving Co-trimoxazole, and avoid artesunate + amodiaquine if they are also receiving efavirenz or zidovudine.
  • 3.4Non-immune travellers:
  • Note: Treat travellers with uncomplicated P. falciparum malaria returning to nonendemic settings with an ACT.
  • 3.5Uncomplicated hyperparasitaemia
  • Note People with P. falciparum hyperparasitaemia are at increased risk of treatment failure, severe malaria and death so should be closely monitored, in addition to receiving an ACT
  • 4. Treatment of uncomplicated malaria caused by P.Vivax, P. ovale, P.Malariae Or P. Knowlesi
  • 4.1 Uncomplicated malaria caused by P.Vivax
  • 4.1.1'In areas with chloroquine-sensitive P. vivax
  • Preferred regimen: Chloroquine PO total dose of 25 mg base/kg bw. Chloroquine is given at an initial dose of 10 mg base/kg bw, followed by 10 mg/kg bw on the second day and 5 mg/kg bw on the third day.
  • 4.1.2'In areas with chloroquine-resistant P. vivax
  • Note:ACTs containing piperaquine, mefloquine or lumefantrine are the recommended treatment, although artesunate + amodiaquine may also be effective in some areas. In the systematic review of ACTs for treating P. vivax malaria, dihydroartemisinin + piperaquine provided a longer prophylactic effect than ACTs with shorter half-lives (artemether + lumefantrine, artesunate + amodiaquine), with significantly fewer recurrent parasitaemias during 9 weeks of follow-up.
  • 4.2 Uncomplicated malaria caused by P. ovale, P.Malariae Or P. Knowlesi malaria
  • Note: Resistance of P. ovale, P. malariae and P. knowlesi to antimalarial drugs is not well characterized, and infections caused by these three species are generally considered to be sensitive to chloroquine. In only one study, conducted in Indonesia, was resistance to chloroquine reported in P. malariae. The blood stages of P. ovale, P. malariae and P. knowlesi should therefore be treated with the standard regimen of ACT or chloroquine, as for vivax malaria.
  • 4.3 Mixed malaria infections
  • Note: ACTs are effective against all malaria species and so are the treatment of choice for mixed infections.
  • 4.4Treatment of liver stages( Hypnozoites) of P. Vivax and P.Ovale
  • Note:To prevent relapse, treat P. vivax or P. ovale malaria in children and adults (except pregnant women, infants aged < 6 months, women breastfeeding infants < 6 months, women breastfeeding older infants unless they are known not to be G6PD deficient and people with G6PD deficiency) with a 14-day course of primaquine in all transmission settings. Strong recommendation, high-quality evidence In people with G6PD deficiency, consider preventing relapse by giving primaquine base at 0.75 mg base/kg bw once a week for 8 weeks, with close medical supervision for potential primaquine-induced adverse haematological effects.]
  • 4.5Primaquine for preventive relapse
  • 4.5.1Preferred regimen: Primaquine PO 0.25–0.5 mg/kg bw per day qd for 14 days
  • 4.5.2Primaquine and glucose-6-phosphate dehydrogenase deficiency
  • Preferred regimen:Primaquine PO 0.75 mg base/kg bw once a week for 8 weeks.
  • Note::The decision to give or withhold primaquine should depend on the possibility of giving the treatment under close medical supervision, with ready access to health facilities with blood transfusion services.
  • 4.5.3Prevention of relapse in pregnant or lacating women and infants
  • Note:Primaquine is contraindicated in pregnant women, infants < 6months of age and in lactating women (unless the infant is known not to be G6PD deficient).
  • 5.Treatment of sever malaria
  • 5.1 Adults and children with severe malaria (including infants, pregnant women in all trimesters and lactating women):-
  • Preferred regimen: Artesunate IV/IM for at least 24 h and until they can tolerate oral medication. Once a patient has received at least 24 h of parenteral therapy and can tolerate oraltherapy, complete treatment with 3 days of an ACT (add single dose Primaquine in areas of low transmission).
  • 5.2 Young children weighing < 20 kg
  • Preferred regimen:Artesunate (3 mg/kg bw per dose)
  • Alternatives regimen: use Artemether in preference to quinine

for treating children and adults with severe malaria

  • 5.3Treating cases of suspected severe malaria pending transfer to a higher-level facility (pre-referral treatment)
  • 5.3.1 Adults and children
  • Preferred regimen: Artesunate IM
  • Alternative regimen: Artemether IMOR Quinine IM
  • 5.3.2 Children < 6 years
  • Preferred regimen: Where intramuscular injections of artesunate are not available , treat with a single rectal dose (10 mg/kg bw) of Artesunate, and refer immediately to an appropriate facility for further care.
  • Note: Do not use rectal artesunate in older children and adults.
